Queerphobia is defined as society's negative attitude towards LGBTQIA + people, translating into structures that marginalise LGBTQIA + people and contribute to health inequities that cause real harm and can be understood as structural violence. The purpose of this article is to explore what historically marginalised youth in a youth participatory action research (YPAR) project characterise as the big picture issues affecting the lives of LGBTQIA + youth. We used participatory arts-based methods to conduct community and identity building, define research questions and photo prompts, conduct data collection, engage in group thematic analysis, and make recommendations at the state policy level.

Positive outcomes from undergraduate research experiences (UREs) have resulted in calls to broaden and diversify participation in research. However, we have little understanding of what demographics are reported and considered in the analyses of student outcomes from UREs. Without this information, it is impossible to assess whether participation in UREs has been diversified and how outcomes may vary by participant identity.

Article Synopsis
  • Bacteria found in bats produce valuable secondary metabolites and show significant genomic diversity based on the species of bat and cave location they inhabit.
  • A study analyzed the genomes of 132 bacterial isolates from 11 species of insectivorous bats across six cave sites in Arizona and New Mexico, revealing that bacterial isolates from the same bat species or cave had higher genomic similarity.
  • Despite the ecological influence on genomic similarity, the distribution of biosynthetic gene clusters (BGCs) was not limited to specific bat species or sites, highlighting the rich diversity of BGCs present across various bat species which could inform future natural product research.

Despite great strides in the development of contraceptive technologies, the United States has one of the highest teen pregnancy rates in the world. Religion and associated values may shape the sexual health behaviors of college students, as prior studies have aimed to determine how social factors may influence the use of contraception amongst college students. Thus, we sought to examine the differences in current contraceptive methods and the age of first contraceptive usage among sexually active female college students with different religious affiliations and strengths of religiosity.

Structural inequities influence young parents' access to health care, housing, transportation, social support, education, and income. The current study adds to the extant literature by providing data directly obtained in collaboration with young parents to understand how structural violence affects the health and well-being of their families, ultimately resulting in community-driven policy recommendations developed in collaboration with the state health department. We engaged a diverse sample of young people-considered as community researchers in the project-including Black, Latinx, and/or LGBTQ+ pregnant and parenting young parents in a participatory action research (PAR) project in the spring of 2022 to explore their health and material needs while living in Springfield, Massachusetts.

Background: Adolescent substance use is a significant issue which occurs during a critical period of life of youth. Perceived stress is a risk factor for adolescent substance use, and life events such as low family support, and community and familial turmoil often lead to ongoing feelings of stress and uncertainty. Similarly, structural factors such as poverty, local neighborhood disinvestment and disrepair, and exposure to racism and discrimination are linked to feelings of stress.

Purpose: Task-based assessment of image quality in undersampled magnetic resonance imaging provides a way of evaluating the impact of regularization on task performance. In this work, we evaluated the effect of total variation (TV) and wavelet regularization on human detection of signals with a varying background and validated a model observer in predicting human performance.

Approach: Human observer studies used two-alternative forced choice (2-AFC) trials with a small signal known exactly task but with varying backgrounds for fluid-attenuated inversion recovery images reconstructed from undersampled multi-coil data.

This community-based participatory research study explores the influence of structural racism on sexual and reproductive health (SRH) inequities among immigrant, including refugee, youth. We conducted interviews with emerging youth and youth service providers living in two communities in Massachusetts. Our results detail three major themes illustrating how structural racism influences SRH inequities among immigrant youth: (1) lack of culture-centered SRH supports for recently immigrated youth; (2) immigration enforcement and fear impacting access to adolescent SRH (ASRH) education and services; and (3) perceived ineligibility related to tenuous legal status as a barrier to accessing ASRH services.

Background: It is challenging to develop health promotion interventions created in collaboration with communities affected by inequities that focus beyond individual behavior change. One potential solution is interventions that use digital stories (DS). Digital storytelling (DST) is an opportunity for reflection, connection with others, and the elevation of voices often absent from daily discourse.

Background: Intermittent fasting (IF), consisting of either a one-day (IF1) or two consecutive days (IF2) per week, is commonly used for optimal body weight loss. Our laboratory has previously shown an IF1 diet combined with 6d/week of protein pacing (P; 4-5 meals/day evenly spaced, ~ 30% protein/day) significantly enhances weight loss, body composition, and cardiometabolic health in obese men and women. Whether an IF1-P or IF2-P, matched for weekly energy intake (EI) and expenditure (EE), is superior for weight loss, body composition, and cardiometabolic health is unknown.

Polyketide synthases (PKSs) are multidomain enzymes in microorganisms that synthesize complex, bioactive molecules. PKS II systems are iterative, containing only a single representative of each domain: ketosynthase alpha (KS[Formula: see text]), ketosynthase beta and the acyl carrier protein. Any gene encoding for one of these domains is representative of an entire PKS II biosynthetic gene cluster (BGC).

Introduction: When it is offered, sexuality education in the USA is far from standardized. While studies have explored differences in delivery and type of sexuality education across the USA, sexual and reproductive health inequities persist among historically marginalized groups (Latino/a/x, Black, African American, LGBTQ +). There is a critical need to better understand the systemic barriers to receiving effective sexuality education in these communities.

Comparative study of haloperidol (HPD), biperiden (BPD) and clonazepam (CNZ) interactions with human and bovine serum albumin was performed based on fluorescence quenching analysis. We used mathematical modeling comparing spectrofluorimetric data to obtain information on the possibility of competition among three drugs by sites binding. Results showed that the three drugs studied have high affinity for albumin and suggest the existence of two site classes in HSA for HPD and only one class for BPD and CNZ, in the range of concentrations tested for each drug.

The 2017 revitalization of the controversial Security Communities program, which requires local law enforcement to cooperate with federal immigration officials in the United States, has made it urgent to better understand such enforcement programs' effects on the well-being of Latinas/os, especially the foreign-born. Social isolation from increased immigration enforcement can have significant impacts on economic, social, and health outcomes among Latina/o immigrants and non-immigrants. This article analyzes the gendered impacts of different levels of increased local involvement in immigration enforcement on social isolation, using a survey of over 2000 Latinas/os in four large US cities, all considered to be traditional destinations.
