Sexual Racism and Queer Asian American Men's Depression and Hazardous Drinking.

J Homosex

January 2025

Department of Psychology, Bryn Mawr College, Bryn Mawr, Pennsylvania, USA.

While research suggests that sexual racism is prevalent within the gay community, studies have neglected to examine how this specific manifestation of racism influences queer Asian American men's mental health. Queer Asian American men's health outcomes are often overlooked as racism-related studies tend to homogenize queer Asian American men with queer men of color broadly. Thus, the present study examined the association between sexual racism and queer Asian American men's depressive symptomatology and hazardous drinking, as well as the moderating role of collective racial self-esteem.

Unlabelled: During infection, bacterial pathogens rely on secreted virulence factors to manipulate the host cell. However, in gram-positive bacteria, the molecular mechanisms underlying the folding and activity of these virulence factors after membrane translocation are not clear. Here, we solved the protein structures of two secreted parvulin and two secreted cyclophilin-like peptidyl-prolyl isomerase (PPIase) ATP-independent chaperones found in gram-positive streptococcal species.

The nuclear pore complex (NPC) is the proteinous nanopore that solely regulates molecular transport between the nucleus and cytoplasm of a eukaryotic cell. Hypothetically, the NPC utilizes the hydrophobic barriers based on the repeats of phenylalanine-glycine (FG) units to selectively and efficiently transport macromolecules. Herein, we quantitatively assess the hydrophobicity of transport barriers confined in the nanopore by applying scanning electrochemical microscopy (SECM).

Introduction: Recovery community centers (RCCs) offer various support services to people in addiction recovery, such as hosting mutual help meetings and sober social activities and providing employment support and recovery coaching. To date, very little is known about RCCs and their relationship with recovery outcomes, as well as how RCCs may vary in helpfulness from visit to visit. This study used a daily diary approach to assess the intraindividual variation of daily RCC helpfulness, and whether RCC helpfulness predicted the holistic recovery indices of daily meaningfulness and recovery identity.

Neurodevelopmental impairments associated with congenital heart disease (CHD) may arise from perturbations in brain developmental pathways, including the formation of sulcal patterns. While genetic factors contribute to sulcal features, the association of noncoding variants (ncDNVs) with sulcal patterns in people with CHD remains poorly understood. Leveraging deep learning models, we examined the predicted impact of ncDNVs on gene regulatory signals.
