Applications of Immersive Virtual Reality for Illicit Substance Use: A Systematic Review.

Objective: This study aims to review applications of immersive, head-mounted display (HMD)-delivered virtual reality (VR) technology for the assessment and modification of clinically relevant factors (e.g., craving, electrophysiological reactions, brain activation) present in illicit substance use.

Opioid Literacy Among Individuals Living in Rural Alabama: The Role of Social Determinants of Health.

Using the social determinants of health (SDOH) framework, the current study aimed to examine opioid literacy and the role of SDOH on opioid literacy. This study used a cross-sectional survey design to collect self-reported data from people living in four rural Alabama counties affected by the opioid crisis. Participants reported moderate levels of opioid knowledge.

Racial and ethnic differences in retrospective end-of-Life outcomes: A systematic review.

The purpose of this systematic review was to provide a comprehensive account of racial and ethnic differences in retrospective end-of-life outcomes. Studies were searched from the following databases: Abstracts in Social Gerontology, Academic Search Premier, CINAHL Plus with Full Text, ERIC, MEDLINE, PsycINFO, PubMED, and SocIndex. Studies were included if they were published in English, included people from groups who have been minoritized, included adults aged 18 and older, used retrospective data, and examined end-of-life outcomes.

The association between social determinants of health and psychological distress during the COVID-19 pandemic: a secondary analysis among four racial/ethnic groups.

Background: Racial disparities in psychological distress associated with COVID-19 remain unclear in the U.S. This study aims to investigate the associations between social determinants of health and COVID-19-related psychological distress across different racial/ethnic groups in the US (i.

Impact of COVID-19 among people who use drugs: A qualitative study with harm reduction workers and people who use drugs.

Background: Fatal drug overdoses in the USA hit historical records during the COVID-19 pandemic. Throughout the pandemic, people who used drugs had greater odds of contracting COVID-19, increased drug use due to COVID-related stress, and heightened levels of anxiety and depression. This qualitative study examined the specific ways the pandemic negatively impacted people who use drugs.

Deficiency in RCAT-1 Function Causes Dopamine Metabolism Related Behavioral Disorders in .

When animals are faced with food depletion, food search-associated locomotion is crucial for their survival. Although food search-associated locomotion is known to be regulated by dopamine, it has yet to investigate the potential molecular mechanisms governing the regulation of genes involved in dopamine metabolism (e.g.

Impact of COVID-19 Among People Who Use Drugs: A Qualitative Study With Harm Reduction Workers and People Who Use Drugs.

Fatal drug overdoses in the United States hit historical records during the COVID-19 pandemic. Throughout the pandemic, people who used drugs had greater odds of contracting COVID-19, increased drug use due to COVID-related stress, and heightened levels of anxiety and depression. This exploratory qualitative study examined the specific ways the pandemic negatively impacted people who use drugs.

MGL-1 on AIY neurons translates starvation to reproductive plasticity via neuropeptide signaling in Caenorhabditis elegans.

Reproductive plasticity is the ability of an animal to modulate its reproductive functions in response to environmental changes. For example, Caenorhabditis elegans, a free-living nematode, can adjust the onsets of oogenesis and embryogenesis under harsh environmental conditions, including starvation. However, the molecular mechanisms used to perceive and translate environmental signals into reproductive functional adjustments remain largely uncharacterized.

A conserved neuronal DAF-16/FoxO plays an important role in conveying pheromone signals to elicit repulsion behavior in Caenorhabditis elegans.

Animals use pheromones as a conspecific chemical language to respond appropriately to environmental changes. The soil nematode Caenorhabditis elegans secretes ascaroside pheromones throughout the lifecycle, which influences entry into dauer phase in early larvae, in addition to sexual attraction and aggregation. In adult hermaphrodites, pheromone sensory signals perceived by worms usually elicit repulsion as an initial behavioral signature.
