This systematic review aims to determine how social media contributes to feelings of social isolation or connectedness among college students at the University of California, Berkeley.</p><p>We conducted a university-wide survey to determine how college students feel about using social media. Using cluster analysis and the data analysis program R, we determined that most college students feel socially connected while using social media. While some past research articles support this theory, most do not discuss the ways in which college students generally tend to feel socially connected on social media platforms. Our paper explores specific factors contributing to college students’ social connectedness... https://escholarship.org/uc/item/8z10r7v1 Sun, 27 Oct 2024 00:00:00 +0000 Nanda, Heer Gharabi, Ameneh Wang, Elizabeth Kolhatkar, Kayhan Choi, Seo Jin Le, Trang Chaisomboonpan, Yanisa https://escholarship.org/uc/item/8x88972w The goal of this literature review is to analyze different herbal medicine treatment options for Glioblastoma, a highly malignant cancer that starts as a growth of cells in the brain or spinal cord. The four different herbal medicine treatments that are studied in the paper are Curcumin, Flavonoids, Quercetin, and Terpenoids. Curcumin is used as a key inhibitor in various pathways in the cell proliferation and apoptosis of GBM cells. Flavonoids regulate tumor cell glucose metabolism by preventing cancer cells from uptaking glucose and cannot harness energy in the form of ATP. Quercetin is targeted at glioma cancer growth without negatively impacting normal CNS cells. Terpenoids are used to inhibit the transfer of P-glycoprotein, which can inhibit glioblastoma formation. All four herbal treatments have been shown to slow the progression of Glioblastoma by inhibiting the proliferation of Glioblastoma cells. This can be seen through the decrease in the tumor size of Glioblastoma patients. https://escholarship.org/uc/item/8x88972w Sun, 27 Oct 2024 00:00:00 +0000 Pham, Hieu Garimella, Mallika Yu, Tiffany Cho, Rachel Fukushima, Yasmin Chen, Jeffrey https://escholarship.org/uc/item/8n45n0rx Climate change poses a significant challenge to global human health, particularly impacting vulnerable populations such as infants, children, and youths. Despite growing awareness of its environmental effects, the relationship between climate change and human health remains underexplored. This study aims to address this gap by conducting an observational analysis of the association between climate change, characterized by the total greenhouse gas emissions from the Worldbank database, and stillbirths, neonatal, under-5 and child and youth (ages 5 – 24) mortality rates from the UNICEF database. By stratifying the analysis based on UNICEF regions, this study seeks to explore the spatial and temporal patterns to provide insights for policymakers, non- governmental organization, and the public to target interventions effectively. The results reveal complex relationships with varying mortality rates across UNICEF regions despite the differing levels of greenhouse gas emissions. Across... https://escholarship.org/uc/item/8n45n0rx Sun, 27 Oct 2024 00:00:00 +0000 Subijanto, Caitlin Kelley, Hannah Cho, Jamie Sainarayanan, Anusha https://escholarship.org/uc/item/70649783 California has the largest homeless population in the nation, with a significant gap between the demand and supply of affordable housing. This disparity not only undermines the quality of life and educational opportunities for residents but also poses grave health risks. This study investigates the nexus between social policies and homelessness in California. By analyzing systemic factors such as exorbitant housing costs and inadequate social safety nets, we uncover the root causes of housing instability. Our examination extends to exploring the multifaceted health disparities experienced by homeless individuals, particularly older adults, and elucidating the complex interplay of mental health struggles within this demographic. Findings reveal that prevailing social policies significantly contribute to homelessness, exacerbating health inequities among vulnerable populations. Our analysis stresses the urgent need for evidence-based policy reforms and holistic, community-based... https://escholarship.org/uc/item/70649783 Sun, 27 Oct 2024 00:00:00 +0000 Hsiao, Paula Wahab, Asim Hwang, Jay Bindra, Melina https://escholarship.org/uc/item/6mg3r54p Cannabis, derived from the Cannabis sativa plant, has historically been utilized for its medicinal properties, notably for pain management and symptom relief in various health conditions. Recent research has expanded its potential therapeutic applications, particularly in cancer treatment and chronic pain management. This paper explores the role of two primary cannabinoids, Delta9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in addressing cancer-related symptoms and chronic pain. THC and CBD have demonstrated significant anti-tumor and anti-inflammatory activities, which are mediated through interactions with the endocannabinoid system (ECS). THC primarily targets CB1 receptors to modulate pain and neuroinflammation, while CBD exerts effects through a more complex mechanism involving various receptors, including CB2, TRPV1, and 5-HT1A. The paper reviews clinical and preclinical studies to elucidate the efficacy of these cannabinoids in alleviating symptoms such as pain, anxiety,... https://escholarship.org/uc/item/6mg3r54p Sun, 27 Oct 2024 00:00:00 +0000 Ansari, Haya Huang, Yujing Lizarraga, Alyssa Tu, Tiffany https://escholarship.org/uc/item/5ns029bd Our study focuses on the impact of the pesticide DDT on maternal and child health, specifically in relation to obesity and breast cancer. The objective is to investigate the interdependence of obesity and breast cancer resulting from DDT exposure on a hormonal level, particularly estrogen, and to understand the association between DDT exposure and maternal and child health. The methodology employs a meta-analysis approach, analyzing independent studies on DDT's impacts on obesity and breast cancer, and examining the correlation between maternal DDT exposure and obesity, as well as the impact of obesity on breast cancer gene mutations. The study population primarily consists of mothers and their newborn children from the United States, with a focus on the persistence of DDT in regions such as South America, Africa, and Asia. Additionally, rodent studies were analyzed to see the impacts of DDT on generational development and reproduction. The data analysis is drawn from primary... https://escholarship.org/uc/item/5ns029bd Sun, 27 Oct 2024 00:00:00 +0000 Neravetla, Arushi Sengupta, Trisha Sulivar-Monis, Raylene A Son, Emily Ravichandran, Meghaa https://escholarship.org/uc/item/5j55830n This research paper explores the multifaceted impact of COVID-19 on minority groups, focusing on two key aspects: vaccination rates and public trust in the government. Through a comprehensive literature review, the vaccination rates within various minority groups are examined, revealing disparities particularly prevalent among African Americans and refugees. Factors contributing to these disparities, including districts in the government, are identified and analyzed. Additionally, the paper investigates the influence of public health policies on political trust both domestically and internationally. By studying different policies implemented during the pandemic, the research aims to assess their effectiveness in fostering public trust and enhancing the overall welfare of the population. This research contributes to a deeper understanding of the complex interplay between COVID-19, minority communities, vaccination rates, public trust, and governmental policies, offering valuable... https://escholarship.org/uc/item/5j55830n Sun, 27 Oct 2024 00:00:00 +0000 Mao, Mo Giron, Stephanie Chang, Austin Subramanian, Subha https://escholarship.org/uc/item/4mk34356 Probiotics are known for providing health benefits, calling for clinical result testing on subjects. We focus on the biological effects of the following probiotics to find their potential to help neurological disorders: Lactobacillus brevis, Enterococcus, and Bifidobacterium longum. We delve into how probiotics work with the gut-brain axis—the communication center between the central and the enteric nervous system—and its effect on different neurological disorders through an extensive literature review. We found that Lactobacillus brevis helps the immune system with the potential to help with stress and anxiety disorders. Bifidobacterium longum has been shown to help age-associated disorders like Alzheimer’s and reduce severe stress levels. Enterococcus has been shown to help neuroinflammation-based diseases like Parkinson’s. Enterococcus is also shown to be more present in people with depression than without. These results bring attention to specific probiotic potential in helping... https://escholarship.org/uc/item/4mk34356 Sun, 27 Oct 2024 00:00:00 +0000 Lee, Vivian Chan, Morgan Moon, Patricia Ruiz, Nailah Chavez, Ariana Jain, Ananya Khandaqji, Faris https://escholarship.org/uc/item/4hz556qg This study investigates the connection between antimicrobial resistance (AMR) and climate change across diverse global regions. The study focuses on Mexico, Southeast Asia, and Canada. By analyzing how regional climatic conditions such as temperature, humidity, and seasonal weather patterns influence AMR dynamics, the research can address the critical question of how to tackle AMR. Based on the global escalation of AMR and its profound implications for public health, our study is vital in highlighting the necessity for integrated climate change mitigation strategies within AMR management. The findings emphasize the urgency of surveillance, targeted research, and enforcing strict antimicrobial stewardship to counteract the rising threat of AMR, thereby informing more effective global health responses and policy-making in an era of significant environmental change. https://escholarship.org/uc/item/4hz556qg Sun, 27 Oct 2024 00:00:00 +0000 Raxwal, Tejas Liang, Ashley Lindo, Ava Hernandez, Brisa https://escholarship.org/uc/item/21r27140 There exists a notably high level of dissatisfaction among lower-limb amputee patients fitted with their affiliated prosthetics. Approximately 40%-60% of amputee patients have been surveyed as dissatisfied with their prostheses. Fifty-seven percent are dissatisfied with the comfort of their prostheses, and over 50% report pain while using their prostheses. Rejection of the prosthesis can be seen as the ultimate expression of dissatisfaction with the prosthesis and occurs in up to 31% of cases of prostheses prescribed to armed forces service members with lower limb amputations, mainly as a result of technical problems (e.g., “too much fuss” during use and the prosthesis being “too heavy”). As a solution to this significant surveyed dissatisfaction, our study attempts to utilize a unique model known as the ‘BirdBot Model’–a lower limb prosthetic model inspired by the biomechanics of emu and ostrich (flightless birds) leg limbs– to explore how the model’s design, movement capabilities,... https://escholarship.org/uc/item/21r27140 Sun, 27 Oct 2024 00:00:00 +0000 Rahai, Tara Singh, Sukriti Kim, Jiho Yu, Jennifer Villaroman, Alinna https://escholarship.org/uc/item/1c51b35p Several studies indicate the lack of a comprehensive understanding of climate change among the youth populations. However, perspectives regarding the socio-ecological factors influencing climate anxiety in young people have yet to be accomplished. We were able to report this in terms of a survey that collected data regarding participants’ levels of climate anxiety, demographic information, and perceptions of various socio-ecological factors. Although the sample size was limited, with this method, we gathered insight and opinions regarding effective strategies to address and alleviate anxiety surrounding the global climate change issue, specifically regarding the students in the University of California, Berkeley from varying demographic backgrounds. Such exposure to a range of perspectives contributed to varying levels of concern and engagement with climate change issues. The importance of individual and collective action to address climate change and its psychological impacts... https://escholarship.org/uc/item/1c51b35p Sun, 27 Oct 2024 00:00:00 +0000 Barua, Snigdha Lin, Melody Evonne Pattar, Navreet Kaur Ta, Aileen Tam Stephenson, Lena Marra Wong, Clarissa https://escholarship.org/uc/item/0v99m295 Breast Cancer remains a significant health issue, with roughly around 42,000 maternal deaths occurring each year. The relationship between exercise and breast cancer has been widely studied with substantial evidence suggesting that higher exercise can lower breast cancer proliferation. The meta analysis aimed to investigate the relationship between exercise activating the hormones and receptors of dopamine, insulin, and estrogen and breast cancer across different populations. We conducted a comprehensive search of electronic databases and included studies that reported the association between exercise and the hormones and their impact on breast cancer. Through this analysis, we were able to generate novel mechanisms for the hormones and were able to link exercise and breast cancer. Our findings suggest that an increase in exercise increased the levels of dopamine while lowering insulin and estrogen levels. These effects have a strong relationship with lowering breast cancer proliferation.... https://escholarship.org/uc/item/0v99m295 Sun, 27 Oct 2024 00:00:00 +0000 Chaudhary, Zaim Singh, Jaideep Singh, Kavi Daniel Fanaei, Mahsa Gadiparthy, Megan Ma, Michelle Yingen Nallagatla, Tanvi https://escholarship.org/uc/item/0bb5b93z Dysregulated sleep is often a typical companion of Alzheimer’s disease and other forms of dementia, but the exact relationship between the two remains complex. Beta-amyloid (Aβ) is a protein related to the onset of dementia, with high levels of Aβ plaque buildup being positively correlated with Alzheimer’s disease, but it is unclear by which mechanism Aβ causes dementia. Recent studies have suggested a bidirectional relationship between sleep disturbances and Alzheimer's pathology, wherein disrupted sleep may prevent the clearing of Aβ plaque from the extracellular space, thus exacerbating Aβ accumulation and vice versa, creating a cycle that accelerates cognitive decline. Continuously activated microglia may play a role in the development of neurodegenerative diseases. Microglia are the main sources of brain inflammation, and thus, research indicates that excessively activated microglia can generate elevated levels of proinflammatory cytokines and chemokines, which are neuroimmune... https://escholarship.org/uc/item/0bb5b93z Sun, 27 Oct 2024 00:00:00 +0000 Touserkani, Nicholette Lassalle, Isabella Yang, Aris Jones, Sarah Mach, Amber Gilbride, Kaitlyn Kim, Stephanie Dao, Anton https://escholarship.org/uc/item/01x2z8r4 The RAS protein family functions as binary switch proteins toggling between active (GTP-bound) and inactive (GDP-bound) states, regulating pivotal cellular pathways like PI3K, MAPK, and Ral-GEF. Dysregulation of Ras signaling, often via mutations, leads to constitutive activation of downstream pathways, driving uncontrolled cell proliferation, a hallmark of cancer. Targeting aberrant Ras signaling pathways with small molecular inhibitors represents a promising therapeutic strategy in cancer treatment. This review examines three main approaches: Farnesyltransferase inhibitors (FTIs), upstream regulation of KRAS, and kinase inhibitors targeting RAS effector pathways. FTIs: inhibiting Ras activation, exhibit cytostatic effects on cancer cells, with clinical trials demonstrating promising activity in various cancer types. Sotorasib: a KRAS p.G12C inhibitor, shows efficacy in KRAS p.G12C-mutated cancers, including pancreatic and non-small cell lung cancers, highlighting its potential... https://escholarship.org/uc/item/01x2z8r4 Sun, 27 Oct 2024 00:00:00 +0000 Lee, Celina Nambiar, Nandika Soriano, Lianna Ha, Brandon Mariano, Ralph Vo, Viet https://escholarship.org/uc/item/5p27r08q Replicating and Extending Upon “Hindsight Bias in Depression” https://escholarship.org/uc/item/5p27r08q Mon, 20 May 2024 00:00:00 +0000 Bhardwaj,, Ayushi Eloy Couto Correia, Luiza Kaur Dharni, Noor Jeong, Hannah Kermani, Aaron https://escholarship.org/uc/item/8zd3v64r The Effects of Mindfulness on False Memory Production and the Depression-Focused Attention Link: A Replication and Extension Study https://escholarship.org/uc/item/8zd3v64r Mon, 13 May 2024 00:00:00 +0000 Bol, Kiely Fan, Layla Manwaring, Jeremy Wahab, Asim Reineck, Eva Chikara, Tia Lin, Henry https://escholarship.org/uc/item/6k67s0nk Mood Induction Techniques and Mind-body Practices on Mind-Wandering &amp; Well-being: A Replication and Extension Study https://escholarship.org/uc/item/6k67s0nk Mon, 13 May 2024 00:00:00 +0000 Chang, Fang Hsi Ercingoz, Mira Gonzalez, Daniel Jain, Aman Sidhu, Daleen Spears, Christinie https://escholarship.org/uc/item/62s9z257 The Social Brain Network: Dynamics Of Social Connectivity and Isolation: A Replication and Extension Study https://escholarship.org/uc/item/62s9z257 Mon, 29 Apr 2024 00:00:00 +0000 Brogle, Nicholas Dai, Andrew Edara, Anika Kudriavtsev, Katherine Linares, Adrian Nguyen, Mary Shui, Hong Zhao, Marina Cervera, Megan https://escholarship.org/uc/item/1mb3k613 Comparative Morphological Processing in Adult Chinese-English Bilinguals: Insights from ERP and Electrophysiological Responses https://escholarship.org/uc/item/1mb3k613 Sat, 27 Apr 2024 00:00:00 +0000 Chowdhury, Yeemmin Jajj, Sanjam Ong, Sandra Tahir, Myra Vora, Shreya Liu, Eileen Zhang, Nick https://escholarship.org/uc/item/9114m1xw Replication and Extension of the Comparison of Wrist Actigraphy and Sleep Diaries in Measuring Sleep in Healthy Adults https://escholarship.org/uc/item/9114m1xw Tue, 23 Apr 2024 00:00:00 +0000 Asatryan, Sona Azarmi-Por, Ryan Contreras, Eli Lin, Henry Melwani, Devan Judge, Grace Vuong, Sharon https://escholarship.org/uc/item/9r0155c7 This paper details a theoretical research proposal to explore the efficacy of theevent-related potential (ERP) component P300 as a potential biomarker in the early detection of Alzheimer’s disease. To determine P300’s efficacy as a biomarker, an electroencephalogram test, which monitors and generates data on the electrical activity of the brain via scalp electrodes, and an auditory oddball test, which aims to assess the cognitive functioning of participants, were performed. The auditory oddball test involved playing a series of tones of two different frequencies (one is the standard tone, and the other is the target tone) for participants and having participants press a button whenever they heard a target tone. Accuracy and reaction time were recorded. The aforementioned two tests depicted a strong association between P300 and the cognitive decline of patients with Alzheimer’s Disease (AD), suggesting that this ERP component may be used for the early detection of AD, which may... https://escholarship.org/uc/item/9r0155c7 Tue, 19 Mar 2024 00:00:00 +0000 Lee, Jane Lee, Jean Shah, Avisha Ye, Jean ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/6s28350w Antibody Dependent Enhancement (ADE) is a phenomenon in which viral particles bind to virus-specific antibodies, enhancing their uptake by host cells and resulting in increased viral replication and infection. First discovered while studying dengue virus (DENV) in primates, ADE can be explained by two general mechanisms, depending on the type of virus involved. In DENV infection, ADE manifests as largely different reactivity upon secondary infection with a cross-reactive serotype and this information provides a large implication to the authorization of DENGVAXIA vaccine use. Looking into the need of vaccines considering the current SARS-CoV-2 pandemic, authors are providing a review of current knowledge correlating SARS-CoV-2 and ADE phenomenon. Using SARS-CoV-1 as a model, we can hypothesize the possible ADE pathway in SAR- CoV-2. The S protein binds to the ACE2 receptor on the host cell and triggers different immune responses depending on the titer of antibodies present.

This article aims to analyze the factors most impactful in determining human health, which was done by performing correlational analysis on a myriad of environmental factors. Each of these factors were evaluated by looking at counties or states as a whole and analyzing the strength of correlation between life expectancy in a county/state to a specific metric measuring environmental health, whether that be natural disasters, air quality, average temperature, exercise rate, water quality, walk score, or food security. The strength of correlation is in the form of an r-squared value, which is a metric that gives a measure of how much of a particular independent variable impacts the dependent variable, which here is life expectancy. The results show that lifestyle factors like food and exercise have a larger impact than expected, while factors such as air and water quality have a less... https://escholarship.org/uc/item/6245b8fm Tue, 19 Mar 2024 00:00:00 +0000 Ding, Yifan Tran, Catherine Valdovinos, Ashton Carbonell, Pauline Kantamneni, Namrata ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/6127k4d5 <p>Prokaryotes, such as bacteria, have evolved defense mechanisms that protect them from foreign bodies invading and harming them.1 One of these mechanisms is the clustered regularly interspaced short palindromic repeats (CRISPR), alongside their accompanying CRISPR-associated (Cas) proteins.1 This system functions as an immune response that protects prokaryotes from viruses (and other harmful bodies) by detecting foreign genetic material invading them and disabling their functionality and ability to spread.2 Understanding the underlying mechanism of this immune response allowed scientists around the world to develop CRISPR and adapt it to various uses in gene editing, agriculture, and most recently, diagnosis of infectious and noninfectious diseases.2 &nbsp;The discovery of CRISPR as a biomedical disease detection tool has revolutionized modern day medicine and its accessibility.&nbsp;</p><p>Infectious diseases are those that are caused by microorganisms and easily passed from... https://escholarship.org/uc/item/6127k4d5 Tue, 19 Mar 2024 00:00:00 +0000 Alqahtani, Khaled Dhillon, Sukhdeep Sequeira, Rohin Yang, Amy Aydin, Damla ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/5kn6x4hh An Epidemiological Comparison of COVID-19 Waves in Malaysia https://escholarship.org/uc/item/5kn6x4hh Tue, 19 Mar 2024 00:00:00 +0000 Feinberg, Alyssa Loyola, Alondra Sima, Meti Tom, Chris Yang, Kevin ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/2zw8k5mx Several studies have introduced CRISPR-Cas9 as a prominent genome-editing technology. CRISPR was first established as a bacterial immune system and was later founded as a new genome-editing technology by Jennifer Doudna and colleagues around the turn of the decade. CRISPR is preceded by zinc-finger nucleases (ZFN) and transcription activator-like effector nucleases (TALENs); however, it improves upon these previous genome-editing designs by using RNA as its binding domain and by already containing nucleases—reducing the need to intentionally engineer these domains into the technology. Complementarity between the different RNAs (tracrRNA and crRNA) and protein aspects (Cas systems) of CRISPR act in conjunction to both efficiently assemble and confer its intended purpose. After extensive use in mammalian cell cultures and various model organisms, the CRISPR-Cas system has subsequently been used to mediate several genetic diseases such as sickle cell anemia and some cancers in humans.... https://escholarship.org/uc/item/2zw8k5mx Tue, 19 Mar 2024 00:00:00 +0000 Barsdale, Zach Park, Rebecca Tumelty, Connor ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/1960184v Implications of ACE-I and ARBs on COVID-19 Prognosis in Hypertensive Patients https://escholarship.org/uc/item/1960184v Tue, 19 Mar 2024 00:00:00 +0000 Avalos, Krystina Liu, Grace Yung, Angela Sharma, Ambika ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/0p704840 This is a literature review on the effects of spike mutations in the B1.1.7 SARS-CoV-2 variant and its effect on vaccine efficacy.

This paper explores the impacts of COVID-19 on maternal, neonatal, and childhood health, shedding light on both short-term and potential long-term consequences. The transmission of the virus from mother to child, though relatively low compared to other vertically transmitted diseases, remains a subject of ongoing study. Maternal COVID-19 infection during pregnancy is linked to adverse outcomes such as preterm delivery, cesarean section, preeclampsia, and gestational diabetes. Additionally, COVID-19 infection appears to influence placental pathology, raising concerns about fetal development and health in the long term. The pandemic has exacerbated maternal mental health challenges, including an increased prevalence of postpartum depression.

Breast cancer is known to affect 1 in 8 women and is the second leading cause of cancer deaths in women as well. Treatments are currently being administered mostly in surgical procedures, chemotherapy, and hormone therapy, but current research indicates that there are potential remedies that could alter the metastasis of breast cancer on the DNA level. The usage of CRISPR(Clustered Regularly Interspaced Palindromic Repeats)/Cas9 within breast cancer treatments has grown in popularity immensely in the last decade.

What originally began as a way to decrease an embryo's risk of genetic diseases has now become a way to alter its appearance; this paper aims to challenge the risks of genetic engineering. To dive deeper into our research question, we were able to examine sources on a global level to determine the perspectives of genetic engineering in different parts of the world. As the current field of genetic engineering is under speculation by many providers, evaluating the pros and cons of each scenario can determine the efficacy of genetic engineering. Employing clinical technology and socially ethical framework were two main criterias which were used in determining the parameters in understanding if genetic engineering is a viable treatment option.

Huntington’s disease is caused by an abnormality in the huntingtin (HTT) gene, which leads to the encoding of the mutant huntingtin protein (mHTT). The accumulation of mHTT protein in neurons has been found to cause oxidative stress and inflammatory pathways. Additionally, the abnormality in the HTT gene has been attributed to the abnormal expansion of a CAG trinucleotide repeat sequence. Therefore, some studies used CRISPR/Cas9 to target the mHTT gene, along with genes that play a role in redox regulation, including Nrf2 and SOD2. The results of this study showed a decrease in oxidative stress and greater mitochondrial function. A second study builds on these findings in recognizing the dangers involved with removing the CAG repeat in the gene.

Recent studies have honed in on expectant mothers and their developing fetuses as a large, at-risk population for these exposures. Ambient air pollutant exposure is linked with negative physical, mental, and behavioral health outcomes in both child and mother. Expectant mothers subjected to contaminants (PM2.5 , PM10 , NO2 , O3) over an extended period of time have an increased risk of their child being born prematurely with low birth weight and size, neurological delays, impaired motor and cognitive function, and development of lung related diseases such as cancer and asthma. In their early stages of life, children whose mothers were exposed to air pollutants during pregnancy also had detrimental mental and behavioral health outcomes.

Four drugs being studied in the paper include Donepezil, Memantine, Lecanemab, and Rivastigmine. Donepezil is an acetylcholinesterase inhibitor that is used for patients with mild or moderate AD. Memantine is used to block the overflow of glutamate through NMDA receptors and to treat patients with moderate to severe AD. It can be used in combination therapy with Donepezil and Galantamine. Lecanemab is used to target amyloid-beta plaques and to reduce aggregates. Rivastigmine is a carbamate cholinesterase inhibitor that can be used to inhibit both acetylcholinesterase and butyrylcholinesterase for mild to moderate cases of AD. All four drugs have been shown to slow down the progression of AD by increasing cognitive performance and to improve the quality of life for patients and their caregivers https://escholarship.org/uc/item/4n71x4w8 Sat, 21 Oct 2023 00:00:00 +0000 Ballapuram, Aishwarya Wu, Jenny Oberdorfer, Jack Pham, Hieu Shankar, Sitara Sureshbabu, Srutika https://escholarship.org/uc/item/2g05t3w5 General anesthesia (GA) is a widely used medical intervention, given to patients to eliminate pain during invasive procedures and surgeries, effectively revolutionizing the field of medicine. GA induces a reversible unconscious state by potentiating inhibitory receptors like GABA (γ-aminobutyric acid) receptors. Despite the practical uses of GA, recent studies have raised concerns about the potential risks associated with anesthesia exposure on the brain and cognitive function. In recent studies, these adverse effects, like neuronal death, can cause neurotoxicity despite the reversible and transitory nature of most GAs. In this paper, we discuss the neurological and behavioral outcomes after GA in developing and post-developed brains. These findings highlight serious concern on how GA impacts neurocognition and brain activity in both immature and mature brains and the potential harmful long term effects of GA.

Understanding how the virus spreads is crucial in implementing non-pharmaceutical measures. Previous studies have focused on the effects of urban socio-political measures on the contagion rate, but the fine-grained geographic urban spreading pattern remains an open question. To address this, we analyzed the trajectory data of 197,808 smartphone users (including 17,808 anonymous confirmed cases) in nine cities in China. Our analysis revealed that the spatial distribution of confirmed cases in all cities followed a power-law-like model and the spreading centroid human mobility remained constant over time. We also found that long average traveling distance resulted in a high growth rate of spreading radius and wide spatial diffusion of confirmed cases in the fine-grained geographic model.

The relationship between socioeconomic status (SES) and maternal mortality rates (MMR) has been widely studied, with a growing body of evidence suggesting that lower SES is associated with higher MMR. This meta-analysis aimed to investigate the relationship between SES and MMR across different countries. We conducted a comprehensive search of electronic databases and included studies that reported the association between SES and MMR. We used a random-effects model to estimate the overall effect size and explored potential sources of heterogeneity using subgroup analyses. Our findings suggest that there is a significant inverse association between SES and MMR, with higher SES being associated with lower MMR.

The psychiatric disorders we chose to study are Bipolar Disorder, Schizophrenia, Anxiety, Major Depression, and Parkinson’s Disease. We performed a literature review on 30 articles, with at least 6 studies per illness. We hypothesized that pain perception is altered by psychiatric disorders. Whether pain perception was increased or decreased depended on the type of mental illness. We reviewed research articles that induced pain in healthy controls and patients and recorded the difference in pain tolerance and threshold. The pain stimulus varied from electrical, emotional (photo), thermal, and ischemic. Our findings showed that for schizophrenia and bipolar depression there is a very strong case for a decreased pain sensitivity on account of the disorder.

The ongoing pandemic fueled researchers to study new COVID-19 detection methods that are more efficient and accurate alongside new mutations that are coming to light. COVID-19 testing has been heavily dominated by the utilization of polymerase chain reactions (PCR). However, PCR testing often takes an extended period of time before individuals receive their results and requires the precision of skilled personnel to handle scientific equipment and conduct readings. PCR testing requires a large number of resources to conduct, making it difficult for individuals within the general community to conveniently and quickly get tested in the case of close exposure.

Research on Castleman Disease is, at the moment, very elementary due to the lack of patient population size and previous research. Currently, the only research on Castleman disease covers understanding classifications of the disorder, possible causes ranging from immune deficiencies to cytokines, and genetics (Jiang et al., 2020). Because of the disease’s rarity, scientists have not conducted much research; thus, there is still no cure for this disease, and its cause is largely unknown. We analyzed research publications from sources such as PubMed, Google Scholar, and NIH.

Existing therapeutics are inadequate for the ongoing epidemic of drug resistance TB. The evolutionary push of mutations created is destabilizing global TB control, thereby needing new novel therapies for treatment and screening purposes. In this paper, we propose two potential pathways that target TB through IFN-I signaling and the AhR pathway which allows for more accurate and efficient early screening of TB. Targeting these pathways impacts TB outcome by increasing treatment efficacy and strengthening host defense. IFN-I signaling and the AHR pathway can be seen as potential targets for host directed therapies. https://escholarship.org/uc/item/2m5634t7 Fri, 4 Nov 2022 00:00:00 +0000 Sima, Jessica Lee, Jean Wijaya, Lila Choi, Karissa Coutlakis, Anastasia https://escholarship.org/uc/item/13p5r3wk Although music has been called the universal language, its unifying effects aside, music seems to be universal in a particular biological phenomenon: plasticity. Music experience (defined as either playing, listening to, or creating music) has garnered responsibility for a broad range of processes that can ultimately be unified under the broad umbrella of ‘plasticity’ (Strait, 2012). Plasticity can take many forms and can be developed through numerous avenues. Music is able to play a part in many of those avenues. From the molecular to the individual level, and from the clinical to the basic-science realms, the effects of music on plasticity are intriguing, and its implication in numerous medical settings or neurological functions cannot be understated. https://escholarship.org/uc/item/13p5r3wk Fri, 4 Nov 2022 00:00:00 +0000 Barsdale, Zachary Mao, Mo https://escholarship.org/uc/item/0z62945j This paper analyzes the difference between Acute Lymphoblastic Leukemia (ALL) in adults and children.

Of the many forms of metaperception, this paper aims to further explore the overblown implications effect (OIE), which is a prevalent metaperception error where one overestimates how much other people think of their successes or failures. We conducted a mixed ANOVA analysis and found further support for the statistically significant discrepancy between actors’ metaperception ratings and observers’ social perception ratings. For the extension, we continue to explore whether a longer rating duration for the actors would result in more accurate predictions of observers’ ratings compared to observers’ actual ratings by running a mixed ANOVA analysis. We hypothesized that increasing the rating duration would decrease the difference between the actors’ metaperception ratings and the observers’ social perception... https://escholarship.org/uc/item/8fw3f6nj Thu, 26 May 2022 00:00:00 +0000 He, Cady Wang, Katharine Liu, Jessica Ercingöz, Deniz Balagula, Karena Lee, Jane https://escholarship.org/uc/item/6sw5v0t5 Declining cognition, physical health, and mental health are common yet major publichealth challenges.

This study focuses on the mental model theory to explore the effect of working memory on reasoning, how mental models are represented internally, and how these features of reasoning vary across developmental stages. We referred to Demiddele et al.’s (2019) methods as the foundation of our analysis of the mental model theory in schoolchildren. The main finding of this study was that when note-taking is available, participants spontaneously draw iconic representations of the information consistent with MMT. Their performances varied with and without notes, with participants generally scoring more points when they took notes.

The personality traits of both the artist and fan can be measured using the Big Five personality traits. Developed in the 1980s to group together personality traits, these traits include openness, conscientiousness, extroversion, agreeableness, and neuroticism. Openness describes an individual’s curiosity, conscientiousness describes being organized or dependable, extraversion describes a person’s inclination to seek stimulation from the outside world, agreeableness describes a person’s tendency to put others’ needs ahead of their own, and neuroticism describes being anxious or irritable. A 2021 study ran a series of three tests that measured the kind of musical preference, demographics, and perception the participants attained (Greenberg et al.). They concluded that there is statistical significance between the personality of an artist and those who self-identified... https://escholarship.org/uc/item/34c0z5bt Thu, 26 May 2022 00:00:00 +0000 Adami, Sean Feng, Ruth Kuo, Allison Noru, Sahana Sanchez, Kellan Shafaeen, Sarah https://escholarship.org/uc/item/0t09k7dh To analyze the development and nature of essentialist beliefs about race in earlychildhood, we replicated Mandalaywala and colleagues’ original study on the topic, in which a “switched-at-birth” task was used to test participants’ beliefs about the heritability of skin color and behavioral/psychological traits. We accessed their data through OSF and implemented quasibinomial and linear regression models using RStudio. As an extension to the original study, models were modified to incorporate participant sex as a variable. Overall, children judged skin color to be more heritable when the race of the birth mother was white but neither participant race nor sex was a strong predictor of general beliefs about the heritability of skin color. As expected, greater outgroup exposure was associated with a decrease in racial essentialism. Additionally, we found that Black participants exhibited higher levels of racial essentialism, and both Black participants and female participants displayed... https://escholarship.org/uc/item/0t09k7dh Thu, 26 May 2022 00:00:00 +0000 Abramsky-Sze, Sofia Mon Kyaw, Yee Maroufkhani, Sherien-Isabelle Rasheed, Maia Shah, Molisha Lee, Erin https://escholarship.org/uc/item/0667f7dg Analogical transfer, or the ability to use similar solutions to solve seemingly dissimilar problems, has been studied in children using tasks that require the support of long-term memory. However, the transfer of solutions that require the use of tools, or objects with certain functional parts, has not been studied in great depth. This paper replicates and extends upon data collected from a novel study that investigated the role of age and memory on analogical transfer across children who attend public preschools in southern Sweden (Bobrowicz et al., 2020). The purpose of this study was to integrate analogical transfer with functional tool-dependent problem solving and study how both skills develop in toddlerhood. The replication yielded similar results to the original experiment in all five hypotheses tested, with the main finding being that age is not a significant predictor of being able to display analogical transfer from task to task.

Research has yet to examine cognitive mechanisms and the information considered whendeciding between protecting or reporting the offender. We replicated Experiment 2a of Berg Kitayama, &amp; Kross (2021), which investigated how closeness to the offender and crime severity influence the willingness to protect the offender, as well as the attentional mechanisms informing that decision. Using Berg &amp; colleagues’ (2021) data, we also explored whether familial vs. non-familial and romantic vs. non-romantic close relationships with the transgressorinfluenced the willingness to protect them. The findings from our replication of Experiment 2a revealed that people were (1) more likely to protect emotionally close transgressors than distant transgressors; (2) more likely to protect the transgressor... https://escholarship.org/uc/item/6zc3h9tf Tue, 24 May 2022 00:00:00 +0000 Liu, Andie Rahardjo, Alexa Roelofs, Ashley Sreya, Alvi Su, Isabella Zhou, Katie Qu, Deborah https://escholarship.org/uc/item/0dt471ds Previous research has documented that infants as young as six months have intuitions about affiliations regarding shared preferences as well as an understanding of homophily. Homophily ultimately influences friendships, marriages, hiring decisions — the interactions of everyday life. Moreover, understanding shared preferences is relevant to predicting human behavior, as well as guiding child development and socialization.The present study aims to (1) replicate earlier work proving the infants’ understanding of homophily and (2) extend our understanding of infant homophily in regards to characterizing the differences in homophily by sex. Both the replication and extension support the original study by proving the original theory that infants can recognize homophilic attractions. The extension, however, explores the roles that sex and test trial type play in homophily, which the original researchers did not observe. Ultimately, the extension provides preliminary evidence that there... https://escholarship.org/uc/item/0dt471ds Tue, 24 May 2022 00:00:00 +0000 Cho, YeSeul Depew, Isabella Lee, Marissa Sarmiento, Solei Kapoor, Tarunika Weerakoon, Nimangie https://escholarship.org/uc/item/0t34s5b8 <p>Alzheimer’s disease is a neurological condition resulting from the death of neural cells that causes a deprivation in cognitive functionality, communication, and motor skills in patients.

Such disparities explored in this work include the accumulation of alpha-synuclein in the form of Lewy Bodies along with significant changes in the bacterial populations of Akkermansia, Streptococcaceae, Prevotella, and Lactococcus. Specifically, these distinct markers are examined in the context of the enteric system as a means of synthesizing connections between nuanced changes within the gut and the progression of PD. Essentially, this study supports an alternative attempt of better understanding the disease beyond a sole, isolated focus on the brain and central nervous system. Further confounding variables that have been linked to PD are also examined in a similar context; for instance for the variable age, it was indeed found that one of the potential reasons why age is a risk factor for PD can be tied back to the gut through an... https://escholarship.org/uc/item/75n1v8fv Wed, 26 Jan 2022 00:00:00 +0000 Chiok, Kaitlyn Kolanjian, Arsine Lee, Yeji Singh, Tanirika ULAB PHHS Chana, Angikaar S https://escholarship.org/uc/item/9n2618c3 Positive affect, which is known to evoke pleasurable enegagement with one's environment, has well-established potential to reduce the negative effects of stress (Fredrickson, 1998). Although there are various facets of postive affect, we principally examined the alleviating effect of laughter--a common operational defintion of positive affect--on mental and physiological stress responses (Herring et al., 2011). We did so by conducting a replication and extension of a study published by Zander-Schellenberg et al. (2020), who affiirmed the stress-buffering effect of laughter frequency in daily life. In our replication, we attempted to reproduce the findings of the original study, conducted a residual analysis of the statistical models used, and assessed laughter-stress interplay across individual participants. In our extension, we assessed the&nbsp;<em>cumulative</em> stress-buffering effect of laughter frequency in daily life by determining whether the original findings apply to... https://escholarship.org/uc/item/9n2618c3 Thu, 16 Sep 2021 00:00:00 +0000 Raza, Aida Bhatt, Anar Chuang, Joelle Jin, Jing Le, Van Zhang, Miranda https://escholarship.org/uc/item/8cj8s8sw From the moment they are born, infants begin to build an internal model of their physical world. This understanding of physical laws, commonly referred to as intuitive physics, develops over time, enabling individuals to successfully explore and interact with their surroundings. However, the cognitive mechanisms through which humans acquire this understanding of physical quantities, such as mass, are unknown. This paper discusses current understanding of a distinct but foundational part of the intuitive physics engine, mass representation. Current research has localized mass representation to dorsal frontoparietal, ventral-temporal, and dorsal premotor areas of the cortex. However, upon thorough literary analysis, the regions primarily responsible in this process have been narrowed down to the frontal and parietal regions. The extent to which these brain regions are responsible seems to be task dependent, opening avenues for further research to investigate the regions activated... https://escholarship.org/uc/item/8cj8s8sw Thu, 16 Sep 2021 00:00:00 +0000 Shaik, Alisha Catrambone, Hailey Min, Enoch Peter, Kevin Swander, Louie Wong, Stephanie https://escholarship.org/uc/item/81r4m8k3 fMRI has the potential of being able to differentiate between false memory and deception, but to apply this ability to real life situations, such as court cases or in neurodegenerative studies involving the brain's ability to recognize memory, it is vital that fMRI can detect the differences between general memory1 and deception, as false memory is often mixed in with true memory during recollection. To determine whether fMRI can do this, the prior study, “Can fMRI discriminate between deception and false memory? A meta-analytic comparison between deception and false memory studies” (Yu et al., 2019) [18] was extended. Yu et al., 2019 found that true memory and false memory, independently, could be distinguished from deception. This extension aims to determine if brain activity resulting from deception can be distinguished from activity caused by general memory as opposed to false memory. Given the broader scope of general memory compared to false memory, the prediction is put... https://escholarship.org/uc/item/81r4m8k3 Thu, 16 Sep 2021 00:00:00 +0000 Ayat, Noor Candeloza, Louise Davis, Annabel Jaikumar, Adithi Patel, Parth Rocha, Salma Thakur, Aman https://escholarship.org/uc/item/7jh2h32g A core paradox within cognitive science is the emergence of cultural functions, such as writing systems and arithmetic, that develop across time spans far too short for our neural systems to evolve to support them. Previous work has addressed this question with the neural recycling hypothesis, proposing that these newer functions are mapped onto pre-existing interconnected regions of the brain, called neural circuits. We replicated results from a study exploring the specific functions that have been recycled to allow for symbolic subtraction and multiplication. Original findings suggested that numerosity circuitry, typically responsible for comparing the size or quantity of two groups, is employed for subtraction and verbal processing circuitry for multiplication. We reviewed the collected fMRI data to construct a model of the brain with the region responsible for numerosity localized. We confirmed that the region localized by the numerosity task corresponded to the right intraparietal... https://escholarship.org/uc/item/7jh2h32g Thu, 16 Sep 2021 00:00:00 +0000 Kapoor, Tarunika Agulnick, Aaron Muttath, Sheryl Kung, Elly https://escholarship.org/uc/item/65d8n640 The trail-making test (TMT) is a neuropsychological test that is often used to identify cognitive impairment and dementia. This paper replicates a study that utilized the TMT and an fMRI to determine differences in brain activity across 36 healthy participants between the ages of 52 and 85 years old. Two TMTs were given, three trials of TMT-A and three trials of TMT-B, and data was collected on the speed and accuracy of which the participants completed each of the six trials. The replication is focused specifically on determining if there are neuroanatomical regions of the brain that show significantly different activity during the TMT-A and TMT-B, as well as if there was positive or negative activation in those areas. Significant group-level activation in brain regions during the TMT-A versus TMT-B was found using Python, and activation in those significant clusters during both tests was compared using a t-test. The replication yielded different t-statistics compared to the original... https://escholarship.org/uc/item/65d8n640 Thu, 16 Sep 2021 00:00:00 +0000 Vedagarbha, Namrata Chatterjee, Aadrita Medhat, Yasmeen Wong, Katrina Wraich, Rejvir https://escholarship.org/uc/item/5g81c2nm It has been well researched that social hierarchies can determine the developmental outcomes of young children, but little has been studied about the timing of when children develop an understanding of social hierarchies in their respective communities. It was hypothesized that children believe social status co-varies with gender and is unaffected by in-group bias, and that these beliefs are modulated by the child’s own identity. Using multiple tasks that will be discussed in the methods, the hypotheses were tested on children ages 3.5-6.9 years. Results suggest that children use gender as a social cue for status, and boys show in-group bias whereas girls do not. In today’s social climate, it is important to understand children’s development of beliefs in the context of social hierarchies, such as gender, in order to understand the impact of these concepts on self-image, success, and equity. https://escholarship.org/uc/item/5g81c2nm Thu, 16 Sep 2021 00:00:00 +0000 Ghai, Jasleen Fozi, Cameron Ma, Hannah https://escholarship.org/uc/item/4xc6n2bj While there have been previous studies linking beta-amyloid accumulation in the positive range and cognitive decline, there has yet to be substantial research focusing on the significance of beta-amyloid accumulation in the negative range. The present study aims to replicate the findings of the original paper by Landau et al. 2018 which investigated potential associations between subthreshold levels of beta-amyloid accumulation and decreased executive or memory function. Utilizing data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI), longitudinal beta-amyloid accumulation from florbetapir-18 PET scan measurements in cognitively normal individuals and mild cognitively impaired was compared with longitudinal executive and memory function measurements. These findings will provide implications as to whether beta-amyloid accumulation in healthy, cognitively normal individuals may be an earlier indicator of cognitive decline. https://escholarship.org/uc/item/4xc6n2bj Thu, 16 Sep 2021 00:00:00 +0000 Le, Austin Baghai, Mina Juang, Samantha Lam, Jessica Lee, Erin Zhou, Jiayu https://escholarship.org/uc/item/427638w7 In this paper, we detail a theoretical research proposal to investigate the emergence of genderrelated gay males’ and lesbians’ stereotypes using a model called COAT measures which was used in gender stereotypes studies (Liben et al, 2012). Our idea is based on people’s tendency to attribute sexual orientation stereotypes with the opposite gender (Blashill &amp; Powlishta, 2002). Extending on past literature on the early development of gender stereotypes on brilliance in children aged five to seven, we explored whether children in that age range start to perceive and associate gay males and lesbians with gender stereotypes of the opposite gender (Bian et al., 2019). Without carrying out the experiments, we have completed designing the framework of the study and corresponding analysis as well as addressing future ideas to enhance our understanding on the development of gay/lesbian stereotypes.

In this study, our objective is to examine whether sensitivity to fairness develops before infants explicitly show fairness preferences. To further understand this, we replicated Lucca and Pospisil’s (2018) research to test whether infants (13- and 17- month-old infants) prefer to engage with individuals that exhibit fair or unfair behavior. In their study, infants were presented with a novel experimental paradigm in conjunction with video stimuli. Their results suggest that after infants witnessed an individual distribute goods to third parties equally and unequally, infants, both 13 month olds and 17 month olds,&nbsp; actively chose to engage with individuals who distributed goods equally. Given their data, we completed statistical analyses and data manipulation techniques to identify any patterns about inclination towards fair or unfair actors.

Mrvka et al. 2019 set out to demonstrate that voluntary attention given to stimuli intensifies the emotion associated with it. In this paper, we report the results from a replication of the first experiment reported in Mrkva et al. (2019), in which participants’ attention was directed toward a target image. In the original experiment, participants were asked to rate the emotional intensity of the target objects. The perceived distinctiveness and the degree to which participants liked each image were also examined to find out whether either parameter mediates the relationship between emotion and attention. In our replication, participants perceived target images as more emotionally intense than control images, corroborating the results of the original experiment and aligning with our expectations.

The present study utilized longitudinal data from a community-based, nationwide study (n = 2023) to replicate a previous study on how negative affect that persists after a stressor has occurred is related to future health (Leger et al., Psychological science, 29(B), 1283-1290, 2018). Preliminary findings indicated that while certain values (e.g. means, standard deviation) were different from Leger’s due to inconsistencies in the number of participants (n = 1155) included in the original paper, participants who graduated from high school and above experienced more stressors, and tended to be younger. https://escholarship.org/uc/item/2gv9b1px Thu, 16 Sep 2021 00:00:00 +0000 Lee, Ophelia Shenthan, Vasheeigaran Gan, Rachel Lin, Kaleigh Murali, Ashwini https://escholarship.org/uc/item/1d85q1sx Extant research has continually indicated that emotion moderates attention such that attention can be caught, maintained, and/or intensified towards a given emotional object (Mrkva, Westfall, &amp; Van Boven, 2019). However, sparse research has investigated the reverse— whether attention can intensify emotion. To examine the bidirectionality of the relationship between emotional intensity and voluntary attention, we conducted a replication of the Mrkva et al. study on visual attention and emotional intensity. We hypothesized that participants would perceive target images as more emotionally intense than control images, and that their post-search ratings of emotional intensity for each target image would be higher than their pre-search ratings. Each participant was instructed to search for a specific image in a randomized sequence with varying emotional valence in separate trials per participant (Mrkva et al., 2019).
