Diversity and cross-species transmission of viruses in a remote island ecosystem: implications for wildlife conservation.

The ability of viruses to emerge in new species is influenced by aspects of host biology and ecology, with some taxa harbouring a high diversity and abundance of viruses. However, how these factors shape virus diversity at the ecosystem scale is often unclear. To better understand the pattern and determinants of viral diversity within an ecosystem, and to describe the novel avian viruses infecting an individual avian community, we performed a metagenomic snapshot of the virome from the entire avian community on remote Pukenui/Anchor Island in Aotearoa New Zealand.

Lessons Learned from the Implementation of the Wake County, North Carolina EMS Medication for Opioid Use Disorder Program.

Objectives: Buprenorphine has recently emerged as a prehospital treatment for opioid use disorder. Limited data exist regarding the implementation of prehospital buprenorphine programs. Our objective was to describe the development, deployment, lessons learned, and ongoing evolution of the Wake County EMS buprenorphine program using data from the first year following implementation.

Exploration of Cytokines and Microbiome Among Males and Females with Diarrhea-Predominant Irritable Bowel Syndrome.

Background: Whether pathophysiological factors differ between males and females with irritable bowel syndrome-diarrhea (IBS-D) remains to be tested. To better understand potential sex differences, males with IBS-D were compared to naturally cycling females and to females with IBS-D taking hormonal contraception on plasma levels of cytokines and gut microbiome characteristics.

Methods: Males and females with Rome III IBS-D completed questionnaires and kept a daily symptom diary for 28 days.

Expression and purification of Mycobacterium tuberculosis F-dependent glucose-6-phosphate dehydrogenase enzyme using Escherichia coli.

Since their discovery in Mycobacterium tuberculosis (Mtb), F-dependent enzymes have been identified as both important drug targets and potential industrial biocatalysts, including for bioremediation of otherwise recalcitrant substrates. Mtb-FGD1, utilizes glucose 6-phosphate (G6P) as an electron donor for the reduction of F. Current expression systems for Mtb-FGD1 use Mycobacterium smegmatis as host, because of the tendency for it to form inclusion bodies in E.

Adapting Public Health and Health Services Interventions in Diverse, Real-World Settings: Documentation and Iterative Guidance of Adaptations.

When complex public health and health services interventions are implemented in real-world settings, adaptations should be expected, embraced, and studied rather than suppressed and ignored. A substantial amount of recent research has been conducted on the assessment of some types of adaptations, and interest in guiding adaptations to both interventions and implementation strategies is growing. However, there is still a need to investigate the optimal ways to systematically and pragmatically document, analyze, and iteratively guide adaptations as well as to measure the impact of those adaptations on implementation and effectiveness outcomes.
