TL;DR: Overall, IRT appears to be a superb method for epidemiological and taxonomic studies of Leishmania, being sensitive, rapid and quantitative while simultaneously revealing considerable molecular diversity.

TL;DR: Endoplasmic reticulum protein folding, correct glycosylation, vesicular transport to the plasma membrane, gene dosage, secretion signal sequences, and secretome studies are important considerations for improved recombinant protein production.
Abstract: Yeast expression systems have been successfully used for over 20 years for the production of recombinant proteins. With the growing interest in recombinant protein expression for various uses, yeast expression systems, such as the popular Pichia pastoris, are becoming increasingly important. Although P. pastoris has been successfully used in the production of many secreted and intracellular recombinant proteins, there is still room for improvement of this expression system. In particular, secretion of recombinant proteins is still one of the main reasons for using P. pastoris. Therefore, endoplasmic reticulum protein folding, correct glycosylation, vesicular transport to the plasma membrane, gene dosage, secretion signal sequences, and secretome studies are important considerations for improved recombinant protein production.

TL;DR: The reasons underlying the increasing trend in distribution of vector-borne helminths in Europe are investigated, the diagnostic and control strategies currently available are discussed and the authors’ opinion on some topics related to VBH are provided.
Abstract: Presently, 45% of the total human population of Europe, as well as their domestic and companion animals, are exposed to the risk of vector-borne helminths (VBH) causing diseases. A plethora of intrinsic biological and extrinsic factors affect the relationship among helminths, vectors and animal hosts, in a constantly changing environment. Although canine dirofilarioses by Dirofilaria immitis and Dirofilaria repens are key examples of the success of VBH spreading into non-endemic areas, another example is represented by Thelazia callipaeda eyeworm, an emergent pathogen of dogs, cats and humans in several regions of Europe. The recent finding of Onchocerca lupi causing canine and human infestation in Europe and overseas renders the picture of VBH even more complicated. Similarly, tick-transmitted filarioids of the genus Cercopithifilaria infesting the skin of dogs were recently shown to be widespread in Europe. Although for most of the VBH above there is an increasing accumulation of research data on their distribution at national level, the overall impact of the diseases they cause in dogs and humans is not fully recognised in many aspects. This review investigates the reasons underlying the increasing trend in distribution of VBH in Europe and discusses the diagnostic and control strategies currently available. In addition, this article provides the authors’ opinion on some topics related to VBH that would deserve further scientific investigation.

TL;DR: A genome-wide association study of multi- and extensively drug-resistant tuberculosis uses 6,465 Mycobacterium tuberculosis clinical isolates to identify novel mutations associated with resistance and suggest the involvement of efflux pumps in the emergence of resistance.
Abstract: To characterize the genetic determinants of resistance to antituberculosis drugs, we performed a genome-wide association study (GWAS) of 6,465 Mycobacterium tuberculosis clinical isolates from more than 30 countries. A GWAS approach within a mixed-regression framework was followed by a phylogenetics-based test for independent mutations. In addition to mutations in established and recently described resistance-associated genes, novel mutations were discovered for resistance to cycloserine, ethionamide and para-aminosalicylic acid. The capacity to detect mutations associated with resistance to ethionamide, pyrazinamide, capreomycin, cycloserine and para-aminosalicylic acid was enhanced by inclusion of insertions and deletions. Odds ratios for mutations within candidate genes were found to reflect levels of resistance. New epistatic relationships between candidate drug-resistance-associated genes were identified. Findings also suggest the involvement of efflux pumps (drrA and Rv2688c) in the emergence of resistance. This study will inform the design of new diagnostic tests and expedite the investigation of resistance and compensatory epistatic mechanisms.

TL;DR: Although all the BRICS countries have devoted increased resources to health, the biggest increase has been in China, which was probably facilitated by China's rapid economic growth, and India, the second highest economic growth country, has had the least improvement in public funding for health.
