Critical behavioral traits foster peer engagement in Online Mental Health Communities.

Online Mental Health Communities (OMHCs), such as Reddit, have witnessed a surge in popularity as go-to platforms for seeking information and support in managing mental health needs. Platforms like Reddit offer immediate interactions with peers, granting users a vital space for seeking mental health assistance. However, the largely unregulated nature of these platforms introduces intricate challenges for both users and society at large.

Risk assessment of food additives including dietary exposure.

Lately, the entire society's focus has turned towards consuming more natural food products and the production of chemicals obtained utilising green technologies. The use of chemicals as food additives is a concern for consumers. For this reason, the search for natural and more sustainable additives is a key step to control food risks while meeting consumers' requirements.

Plasma membrane remodeling determines adipocyte expansion and mechanical adaptability.

Adipocytes expand massively to accommodate excess energy stores and protect the organism from lipotoxicity. Adipose tissue expandability is at the center of disorders such as obesity and lipodystrophy; however, little is known about the relevance of adipocyte biomechanics on the etiology of these conditions. Here, we show in male mice in vivo that the adipocyte plasma membrane undergoes caveolar domain reorganization upon lipid droplet expansion.

Crystallographic Dependence of Field Evaporation Energy Barrier in Metals Using Field Evaporation Energy Loss Spectroscopy Mapping.

Atom probe tomography data are composed of a list of coordinates of the reconstructed atoms in the probed volume. The elemental identity of each atom is derived from time-of-flight mass spectrometry, with no local chemical information readily available. In this study, we use a data processing technique referred to as field evaporation energy loss spectroscopy (FEELS), which analyzes the tails of mass peaks.

From tyrosine to hydroxytyrosol: a pathway involving biologically active compounds and their determination in wines by ultra performance liquid chromatography with mass spectrometry.

Background: Hydroxytyrosol (HT) is a bioactive compound present in a limited number of foods such as wines, olives, and olive oils. During alcoholic fermentation, yeast converts aromatic amino acids into higher alcohols such as tyrosol, which can undergo hydroxylation into HT. The aim of this study was to validate an analytical method using ultra performance liquid chromatography coupled with mass spectrometry (UPLC/MS-MS) to quantify HT and its precursors (tyrosine, hydroxyphenylpyruvic acid, hydroxyphenylacetaldehyde, 4-hydroxyphenylacetic acid, and tyrosol) in wines.

Commercial wine yeast nitrogen requirement influences the production of secondary metabolites (aroma, hydroxytyrosol, melatonin and other bioactives) during alcoholic fermentation.

During alcoholic fermentation, Saccharomyces cerevisiae synthesizes different compounds, which are crucial for product quality: volatile compounds with sensory impact, and bioactive compounds such as melatonin (MEL) and hydroxytyrosol (HT), linked to health benefits. As many of these compounds are related with yeast's nitrogen metabolism, their production have been studied in four different commercial strains with different nitrogen requirement (Red Fruit, Uvaferm VRB, Lalvin Rhone 2323 and Lalvin QA23) being, Uvaferm UVR the higher nitrogen demander strain. All strains produced the secondary metabolites, notably Uvaferm UVR produced the highest HT concentration, despite its low growth.

The COVID-19 global pandemic has created severe, long-lasting challenges to college students in the United States (US). In the present study, we assessed mental health symptomatology (depression, anxiety, life stress), academic challenges, and economic stress during the first wave of the Coronavirus pandemic. A total sample of 361 college students ( = 22.

Refining an ecological momentary assessment study of binge eating among sexual minority and heterosexual young women: a mixed methods pilot study.

Background: Ecological momentary assessment (EMA) is used to capture daily lived experiences, states, and environments. Although EMA is commonly used in behavioral health research, there remains a dearth of literature on how researchers account for design considerations of EMA techniques when designing studies. The goal of this formative mixed methods study was to elicit feedback on EMA study procedures and materials from the target populations for a larger study about binge eating among sexual minority and heterosexual young women, in which data are collected entirely remotely.

COVID-19 Concerns, Coping and Perceived Peer Norms: Correlates of Increased Alcohol and Marijuana Use Among Sexual Minority Women.

This study explored the impact of COVID-related concerns and other characteristics on alcohol and marijuana use among sexual minority women (SMW). Survey data from a racially/ethnically diverse sample of 338 SMW participants in the Chicago Health and Life Experiences of Women (CHLEW) study were used to examine correlates of three substance use outcomes: frequent intoxication (once a month or more), perceived increase in alcohol use, and perceived increase in marijuana use. Coping motives for alcohol use was positively associated with each of the substance use outcomes.

Evaluating artificial intelligence for comparative radiography.

Introduction: Comparative radiography is a forensic identification and shortlisting technique based on the comparison of skeletal structures in ante-mortem and post-mortem images. The images (e.g.

Righting the historical record: Highlighting the significant contributions of Black psychologists in American schools.

The field of educational psychology, while closely aligned with several adjacent branches of psychology, focuses on teaching and learning processes in support of the development of students within K-16 environments and beyond. Similar to other fields, educational psychology has been historically dominated by theories and empirical studies developed and carried out by White scholars who presented racially and culturally biased ideologies that lacked Black perspectives. Couched within an Afrocentric and Critical Race Theory framework, the present article sets out to right the historical record by uplifting the voices of four prominent Black psychologists who played an important role in American schools and who have been largely ignored in the field of educational psychology.

Climate-driven variation in dispersal ability predicts responses to forest fragmentation in birds.

Species sensitivity to forest fragmentation varies latitudinally, peaking in the tropics. A prominent explanation for this pattern is that historical landscape disturbance at higher latitudes has removed fragmentation-sensitive species or promoted the evolution of more resilient survivors. However, it is unclear whether this so-called extinction filter is the dominant driver of geographic variation in fragmentation sensitivity, particularly because climatic factors may also cause latitudinal gradients in dispersal ability, a key trait mediating sensitivity to habitat fragmentation.

Examining COVID-19 pandemic-related economic and household stress and its association with mental health, alcohol, and substance use in a national sample of Latinx sexual minority and heterosexual adults.

Objective: Sexual minority adults of Latinx descent faced compounded intersectional stressors during the COVID-19 pandemic across socioeconomic and health domains. Latinx people have experienced some of the highest COVID-19 infection, hospitalization, and mortality rates in the United States in addition to significant economic challenges. Yet, current data have not observed the unique pandemic-related experiences of sexual minority Latinx (SML) adults.

Alcohol misuse during the COVID-19 pandemic: Stressors and intersectionality among Latinx women.

Objectives: The COVID-19 pandemic has exacerbated previously existing disparities and introduced new challenges for individuals living at the intersection of marginalized identities, such as Latinx women. For instance, increases in alcohol use have been noted during the COVID-19 pandemic, yet it is unclear which circumstances experienced are more likely to predict alcohol use among Latinx women.

Method: The present study sought to identify the profile of intersectional factors, namely immigrant status, socioeconomic standing, and age, and COVID-19 stressors that predicted high or hazardous alcohol use among 1,227 Latinx women living in the United States.

COVID-19 Economic and Academic Stress on Mexican American Adolescents' Psychological Distress: Parents as Essential Workers.

Objectives: In a sample of Mexican American adolescents ( = 398; 51% females; aged 13-17), we examined the associations between psychological distress, COVID-19 household economic stress, COVID-19 academic stress, and whether these associations varied by adolescents' gender and by parents/caregivers' essential worker status.

Method: First, linear regression models assessed the main effects of household economic and academic stress on psychological distress. Second, the moderating effects of gender and parents/caregivers' essential worker status on the association between household economic and academic stress, and psychological distress were examined.

Geographic mobility and its impact on sexual health and ongoing HIV transmission among migrant latinx men who have sex with men.

An understudied social process that may determine variable HIV risk, testing, and linkage to care is geographic mobility, including immigration as well as short-term mobility, especially among sexual minority populations. We aimed to assess how geographic mobility over the lifecourse between Latin America and the U.S.

Hydroxytyrosol and dopamine metabolites: Anti-aggregative effect and neuroprotective activity against α-synuclein-induced toxicity.

The abnormal aggregation of the α-synuclein (αsyn) protein is involved in the formation of Lewy bodies in the brain of patients suffering from Parkinson disease (PD). Hydroxytyrosol (HT), a polyphenolic compound present in olives, olive oil, and wine, has been shown to inhibit aggregation and destabilise the αsyn aggregates, preventing neuronal cell death. However, very limited data have been published on the study of its metabolites.

Trauma and latinx sexual- and gender-minority immigrants in the U.S.

Due to their multiple minoritized identities, Latinx sexual- and gender-minority immigrants risk exposure to various forms of traumatic stressors at home and abroad that can result in post-traumatic stress disorder and other comorbid problems like depression. A much-needed review and synthesis of the latest research highlights important factors for practitioners and scholars to consider relevant to this vulnerable and under researched population. A data-driven conceptualization helps identify risk factors across different points in time such as violence and discrimination from communal and institutional sources as well as acculturative and minority stressors.

Examining the differential protective effects of women's spirituality and religiosity on alcohol and marijuana use by sexual identity.

The current study explored how religiosity and spirituality may differentially influence substance use by sexual identity based on a sample of adult sexual minority women (SMW; n = 437 lesbian; n = 323 bisexual) relative to a heterosexual comparison sample (n = 636). We examined three questions: (1) whether was differentially associated with alcohol and marijuana use by sexual identity; (2) whether was differentially associated with alcohol and marijuana use by sexual identity; (3) whether observed differences between spirituality or religiosity and substance use by sexual identity persisted after adjusting for religious environment. Measures included spirituality (importance of spirituality), religiosity (importance of religion, attending religious services), and past year substance use (alcohol use disorder [AUD], any marijuana use, and regular marijuana use).

Hydroxytyrosol in Foods: Analysis, Food Sources, EU Dietary Intake, and Potential Uses.

Hydroxytyrosol (HT) is a phenolic compound with proven biological properties present in a limited number of foods such as table olives, virgin olive oil (VOO) and wines. The present work aims to evaluate the dietary intake of HT in the European (EU) population by compiling scattered literature data on its concentration in foods. The consumption of the involved foods was estimated based on the EFSA Comprehensive European Food Consumption Database.

Mitochondrial RNA methyltransferase TRMT61B is a new, potential biomarker and therapeutic target for highly aneuploid cancers.

Despite being frequently observed in cancer cells, chromosomal instability (CIN) and its immediate consequence, aneuploidy, trigger adverse effects on cellular homeostasis that need to be overcome by anti-stress mechanisms. As such, these safeguard responses represent a tumor-specific Achilles heel, since CIN and aneuploidy are rarely observed in normal cells. Recent data have revealed that epitranscriptomic marks catalyzed by RNA-modifying enzymes change under various stress insults.

SAlBi educa (Tailored Nutrition App for Improving Dietary Habits): Initial Evaluation of Usability.

In recent years, the use of applications to improve dietary habits has increased. Although numerous nutrition apps are available on the market, only few have been developed by health and nutrition professionals based on scientific evidence and subsequently tested to prove their usability. The main objective of this study was to design, develop, and evaluate the usability of a tailored nutrition application to be used to promote healthy eating habits.

The citizenship shield: Mediated and moderated links between immigration status, discrimination, food insecurity, and negative health outcomes for latinx immigrants during the COVID-19 pandemic.

A framework termed "the citizenship shield" is introduced to conceptualize how legal protections buffer against negative health outcomes among Latinx immigrants in the United States. In this study, we tested the citizenship shield framework in the context of the disproportionate impact of the COVID-19 pandemic on Latinx immigrants. We investigated the connection between immigration status, discrimination, food insecurity, and negative health outcomes.
