Ergogenic and Sympathomimetic Effects of Yohimbine: A Review.

The purpose of this review is to compile and discuss available evidence in humans on the efficacy of YHM supplementation on performance in different exercise modalities. Yohimbine (YHM) is a naturally occurring alkaloid that induces increases in sympathetic nervous system (SNS) activation effectively initiating "fight or flight" responses. In supplement form, YHM is commonly sold as an isolated product or combined into multi-ingredient exercise supplements and is widely consumed in fitness settings despite the lack of empirical support until recently.

Multidisciplinary Management of Chronic Limb Threatening Ischemia.

Patients with chronic limb threatening ischemia are at high risk for cardiovascular events, mortality, and adverse limb events. A 62-year-old man with diabetes and peripheral artery disease presented with a new foot ulcer with suspicion of infection. Leveraging evidence-based practices, a multidisciplinary team conducted a prompt and thorough evaluation.

Genomic Islands of Divergence Between Drosophila yakuba Subspecies are Predominantly Driven by Chromosomal Inversions and the Recombination Landscape.

During the early stages of local adaptation and speciation, genetic differences tend to accumulate at certain regions of the genome leading to the formation of genomic islands of divergence (GIDs). This pattern may be due to selection and/or difference in the rate of recombination. Here, we investigate the possible causes of GIDs in Drosophila yakuba mayottensis, and reconfirm using field collection its association with toxic noni (Morinda citrifolia) fruits on the Mayotte island.

Is Kraft Pulping the Future of Biorefineries? A Perspective on the Sustainability of Lignocellulosic Product Development.

By reflecting on the history and environmental impact of conventional biorefining, such as kraft pulping, we aim to explore important questions about how natural polymers can be more sustainably sourced to develop bio-products and reduce reliance on plastics. Since the Industrial Revolution, chemical pulping processes have enabled the mass production of cellulosic products from woody biomass. Kraft pulping, which dominates within modern pulp and paper mills, has significantly contributed to environmental pollution and carbon emissions due to sulfurous byproducts and its high water and energy consumption.

The SurVey of barriers for Vaginal access surgerY (SaVVY) Study: The SaVVY Study.

Study Objective: The primary objective of this study was to describe vaginal hysterectomy practice patterns as well as facilitators and inhibitors to performing vaginal hysterectomy among gynecologic surgeons. Secondary objectives were to describe facilitators and inhibitors to the teaching and training of vaginal hysterectomy.

Design: Quantitative analysis of an online survey and qualitative analyses of the one-on-one interviews on gynecologic surgeons was conducted.
