BACKGROUND: Black and Latino minorities have traditionally had poorer access to primary care than non-Latino Whites, but these patterns could change with the Affordable Care Act (ACA). To guide post-ACA efforts to address mental health service disparities, we used a nationally representative sample to characterize baseline race-, ethnicity-, and nativity-associated differences in mental health services in the context of primary care. METHODS: Data were obtained from the Medical Expenditures Panel Survey (MEPS), a two-year panel study of healthcare use, satisfaction with care, and costs of services in the United States (US)...

The indole alkaloid antibiotic chuangxinmycin, from Actinobacteria Actinoplanes tsinanensis, containing a unique thiopyrano[4,3,2- cd]indole scaffold, is a potent and selective inhibitor of bacterial tryptophanyl-tRNA synthetase. The chuangxinmycin biosynthetic gene cluster was identified by in silico analysis of the genome sequence, then verified by heterologous expression. Systemic gene inactivation and intermediate identification determined the minimum set of genes for unique thiopyrano[4,3,2- cd]indole formation and the concerted action of a radical S-adenosylmethionine protein plus an unknown protein for addition of the 3-methyl group...

Nigerian medicinal plants have been demonstrated to be veritable source of lead compounds for drug discovery efforts. One such example is mangiferin. Mangiferin was originally isolated from the Nigerian plant Ceiba pentandra (Mombacaceae), after which its structure was elucidated with the aid of spectroscopy. Mangiferin, a xanthone glycoside, has also been reported in certain other plant families including Gentianaceae and Anacardiaceae. In certain other climes and different parts of the world, folkloric and traditional medicine has extensively employed Mangifera indica (another source of mangiferin) in treating different diseases...

Oral factor Xa inhibitors are increasingly used for anticoagulation, but there is no approved reversal agent. Prothrombin complex concentrate (PCC) for the management of Xa-inhibitor-associated bleeding has been described in small case series and one cohort study. Patients on apixaban or rivaroxaban, suffering a major bleed, were treated at nine Canadian hospitals as per existing hospital protocol with a fixed dose of PCC 2,000 units and subsequently recruited for a 30-day follow-up. The treating physician evaluated the haemostatic effectiveness as observed during the first day as good, moderate or poor/none, using an assessment guide...

Percutaneous approaches for pelvic bone procedures (bone biopsies, tumour ablation and cementoplasty) are multiple and less well systematised than for the spine or extremities. Among the different imaging techniques that can be used for guidance, computed tomography (CT) scan is the modality of choice because of the complex pelvic anatomy. In specific cases, such as cementoplasty where real-time evaluation is a determinant, a combination of CT and fluoroscopy is highly recommended. The objective of this article is to propose a systematic approach for image-guided pelvic bone procedures, as well as to provide some technical tips...

Over the years, the study of gene function during development involved the implementation of sophisticated transgenic strategies to visualize how organisms change during their lifetime. These strategies are diverse and extremely useful and allowed the discovery of some of the fundamental mechanisms governing organism's development. Such strategies can be time-consuming, in some cases expensive, and require complex infrastructure. With the advent of the genome editing CRISPR-Cas9 RNA-guided DNA endonuclease system a tremendous progress has been achieved in manipulating diverse organisms and cell types...
