In the context of discovering and quantifying terminal alkyne-based natural products, here we report the combination of CuAAC click chemistry with LC-MS for the detection of polyether toxins (prymnesins) associated with harmful algal blooms. The added-value of the CuAAC-based approach is evident from our ability to detect novel prymnesin-like compounds in algal species with previously uncharacterised toxins.

Genetic screens have been crucial for deciphering many important biological processes, including meiosis. In Arabidopsis thaliana , previous forward screens have likely identified almost all the meiotic genes that when mutated lead to a pronounced decrease in fertility. However, the increasing number of genes identified in reverse genetics studies that play crucial roles in meiosis, but do not exhibit strong phenotypes when mutated, suggests that there are still many genes with meiotic function waiting to be discovered...

Stroke is one of the leading causes of death worldwide and therapies are limited. According to the mechanisms underlying stroke, direct cell demise, destruction of organelles, blood-brain barrier disruption, neuroinflammation are potential therapeutic targets. Gasdermin (GSDM) family is a series of recently discovered proteins, which acts as the executor of pyroptosis and protagonist of membrane pore formation. It can be cleaved by inflammatory caspases that are activated by multi-protein complexes, named as inflammasomes, and divided into two domains...

The neurobiology of sexual preference is often discussed in terms of cerebral sex dimorphism. Yet, our knowledge about possible cerebral differences between homosexual men (HoM), heterosexual men (HeM) and heterosexual women (HeW) are extremely limited. In the present MRI study, we addressed this issue investigating measures of cerebral anatomy and function, which were previously reported to show sex difference. Specifically, we asked whether there were any signs of sex atypical cerebral dimorphism among HoM, if these were widely distributed (providing substrate for more general 'female' behavioral characteristics among HoM), or restricted to networks involved in self-referential sexual arousal...

Objective Behavioral health services frequently delivered by primary care providers include care for mental health and substance abuse disorders and assistance with behavioral risk factor reduction. Internal medicine residencies in the United States lack formal expectations regarding training in behavioral health for residents. This qualitative study aimed to determine learners' and teachers' perceptions about appropriate behavioral health curricular components for internal medicine residents. Method Focus groups and interviews were conducted with the following individuals from the Duke Outpatient Clinic: residents with continuity practice (n = 27), advanced practice providers (n = 2), internal medicine attending physicians (n = 4), internal medicine/psychiatry attending physicians (n = 2), and behavioral health clinicians (n = 4)...

BACKGROUND: Helicopter Emergency Medical Services (HEMS) are a scarce resource that can provide advanced emergency medical care to unwell or injured patients. Accurate tasking of HEMS is required to incidents where advanced pre-hospital clinical care is needed. We sought to evaluate any association between non-clinically trained dispatchers, following a bespoke algorithm, compared with HEMS paramedic dispatchers with respect to incidents requiring a critical HEMS intervention. METHODS: Retrospective analysis of prospectively collected data from two 12-month periods was performed (Period one: 1st April 2014 - 1st April 2015; Period two: 1st April 2016 - 1st April 2017)...

OBJECTIVE: Metformin use is restricted in patients with renal impairment due to potential excess systemic accumulation. This study evaluated the glycemic effects and safety of metformin delayed-release (Metformin DR), which targets metformin delivery to the ileum to leverage its gut-based mechanisms of action while minimizing systemic exposure. RESEARCH DESIGNS AND METHODS: Participants (T2DM [HbA1c 7-10.5%], eGFR ≥60 mL/min/1.73m2, not taking metformin for ≥2 months) were randomized to QD placebo (PBO); QD Metformin DR 600, 900, 1200, or 1500 mg; or to single-blind BID Metformin immediate-release (IR) 1000 mg...
