Improving first responders' perceptions of overdose events and survivors through tailored occupational health-focused training co-facilitated by overdose survivors.

Background: First responders (law enforcement officers, emergency medical services, and firefighters) frequently interact with people who use drugs (PWUD). Based on the nature and outcomes of such encounters, these interactions have the potential either to reduce harm, or perpetuate it. Given increased funding and attention for first responder-led interventions involving PWUD, we must identify the most critical training for improving negative beliefs about these interventions and populations.

The Causes and Consequences of Stigma among Individuals Involved in the Criminal Legal System: A Systematic Review.

The purpose of this study was to systematically review the types of stigmatized attributes that have been assessed and the causes and consequences of stigma for individuals involved in the criminal legal system. PubMed, GoogleScholar, and PsycInfo databases were searched to identify studies for inclusion through March 2021. Eligible studies were peer-reviewed, quantitative, and assessed stigma from the perspective of the person involved in the criminal legal system.

The tale of two Badakhshans: Determinants of access and utilization of HIV preventive services along the Afghan-Tajik border.

Background: Injection of opioids has contributed to growing HIV epidemics in Tajikistan and Afghanistan. This qualitative study explored determinants of access to primary prevention and screening for HIV among people who inject drugs (PWID) residing in border communities of Gorno-Badakhshan, Tajikistan and Badakhshan, Afghanistan.

Methods: Semi-structured interviews were conducted with PWID, community leaders, and healthcare workers.

De novo transcriptome assembly of a lipoxygenase knock-down strain in the diatom Pseudo-nitzschia arenysensis.

Diatoms are microalgae that live in marine and freshwater environments and are responsible for about 20% of the world's carbon fixation. Population dynamics of these cells is finely regulated by intricate signal transduction systems, in which oxylipins are thought to play a relevant role. These are oxygenated fatty acids whose biosynthesis is initiated by a lipoxygenase enzyme (LOX) and are widely distributed in all phyla, including diatoms.
