Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is commonly seen in malaria endemic areas as it is known to confer a selective advantage against malaria. Recently, we reported a high proportion of asymptomatic reservoir of Plasmodium vivax in Botswana, that calls for intervention with primaquine to achieve radical cure of vivax malaria. Considering that individuals with this enzyme deficiency are at risk of haemolysis following primaquine treatment, assessment of the population for the relative frequency of G6PD deficiency is imperative...

Shayan Falasiri, Tasnif Rahman, Yaping N Tu, Timothy J Fawcett, George Blanck
BACKGROUND: Human mutagenesis has a large stochastic component. Thus, large coding regions, especially cytoskeletal and extra-cellular matrix protein (CECMP) coding regions are particularly vulnerable to mutations. Recent results have verified a high level of somatic mutations in the CECMP coding regions in the cancer genome atlas (TCGA), and a relatively common occurrence of germline, deleterious mutations in the TCGA breast cancer dataset. METHODS: The objective of this study was to determine the correlations of CECMP coding region, germline nucleotide variations with both overall survival (OS) and disease-free survival (DFS)...

REVIEW
Alexander S Kuczmarski, Andrew P Harris, Joseph A Gil, Arnold-Peter C Weiss
Diabetics have a much greater prevalence of trigger finger than nondiabetics and are more likely to have severe symptoms. Diabetic trigger finger may be more accurately described on a spectrum of diabetic hand pathology alongside carpal tunnel syndrome and cheiroarthropathy. Recent publications have called into question the current treatment algorithm for diabetic trigger finger. Although some evidence supports the use of corticosteroid injections, a recent cost analysis reported that immediate surgical release of the A1 pulley in the clinic is the most cost-effective management of diabetic trigger finger...

Because national data on proton pump inbibitors (PPIs) consumption in France are scarce and because there is a growing literature on potential adverse drug reaction induced by this pharmacological class, we would like to more describe the main evolution of PPI use and the main characteristics of its users in France. We used a 1/97th representative sample of beneficiaries of the French health insurance called "échantillon généraliste des bénéficiaires" (EGB) to describe PPIs' use over time (duration of use by year) from 2006 to 2016...

Child protection workers (CPWs) are frequently exposed to client violence, both psychological and physical, in their line of work whether they operate in the community or in residential settings. Despite this known vulnerability, research on the subject has lagged. The current study sought to analyze CPWs' experiences with client violence, their interpretation of it, its perceived consequences and their coping strategies. Specifically, 30 CPWs working both in the community and in residential settings, took part in an in-depth, semi-structured interview...

The overexpression of EGFR often occurs in TNBC, and the anti-EGFR receptor antibody cetuximab is used widely to treat metastatic cancer in the clinic. However, EGFR-targeted therapies have been developed for TNBC without clinical success. In this study, we show that impaired EGFR degradation is crucial for resistance to cetuximab, which depends on the cell surface molecule CD44. To further investigate the role of CD44 in EGFR signaling and its treatment potential, we developed a targeting fusion protein composed of an anti-EGFR scFv generated from cetuximab and truncated protamine, called Ce-tP...

The main intricacy in the human proteome is that it is tremendously complex and composed from diverse and heterogeneous gene products. These products are called protein species or proteoforms and are the smallest units of the proteome. In pursuit of the comprehensive profiling of the human proteome, significant advances in the technology of so called "Top-Down" mass spectrometry based proteomics, have been made. However, the scale of performance of this approach is still far behind the "Bottom-Up", peptide-centric techniques...

Functional connectivity analysis of functional MRI (fMRI) can represent brain networks and reveal insights into interactions amongst different brain regions. However, most connectivity analysis approaches adopted in practice are linear and non-directional. In this paper, we demonstrate the advantage of a data-driven, directed connectivity analysis approach called Mutual Connectivity Analysis using Local Models (MCA-LM) that approximates connectivity by modeling nonlinear dependencies of signal interaction, over more conventionally used approaches, such as Pearson's and partial correlation, Patel's conditional dependence measures, etcetera...

From the early days of cell biological research, the eye-especially the retina-has evoked broad interest among scientists. The retina has since been thoroughly investigated and numerous models have been exploited to shed light on its development, morphology, and function. Apart from various animal models and human clinical and anatomical research, stem cell-based models of animal and human cells of origin have entered the field, especially during the last decade. Despite the observation that the retina of different species comprises endogenous stem cells, most stem cell-related research in the human retina is now based on pluripotent stem cell models...

Microalgae are photosynthetic microorganisms widely used for the production of highly valued compounds, and recently they have been shown to be promising as a system for the heterologous expression of proteins. Several transformation methods have been successfully developed, from which the Agrobacterium tumefaciens-mediated method remains the most promising. However, microalgae transformation efficiency by A. tumefaciens is shown to vary depending on several transformation conditions. The present study aimed to establish an efficient genetic transformation system in the green microalgae Dunaliella tertiolecta using the A...

Donors, practitioners and scholars are increasingly interested in harnessing the potential of social norms theory to improve adolescents' sexual and reproductive health outcomes. However, social norms theory is multifaceted, and its application in field interventions is complex. An introduction to social norms that will be beneficial for those who intend to integrate a social norms perspective in their work to improve adolescents' sexual health in Africa is presented. First three main schools of thought on social norms, looking at the theoretical standpoint of each, are discussed...

Cities are natural laboratories for studying vegetation responses to global environmental changes because of their climate, atmospheric, and biogeochemical conditions. However, few holistic studies have been conducted on the impact of urbanization on vegetation growth. We decomposed the overall impacts of urbanization on vegetation growth into direct (replacement of original land surfaces by impervious built-up) and indirect (urban environments) components, using a conceptual framework and remotely-sensed data for 377 metropolitan statistical areas (MSAs) in the conterminous United States (CONUS) in 2001, 2006, and 2011...

Chemical signals are one means by which many insect species communicate. Differences in the combination of surface chemicals called cuticular hydrocarbons (CHCs) can influence mating behavior and affect reproductive isolation between species. Genes influencing three CHC compounds have been identified in Drosophila melanogaster. However, the genetic basis of other CHC compounds, whether these genes affect species differences in CHCs, and the genes' resulting effect on interspecies mating, remains unknown. We used fine-scale deficiency mapping of the third chromosome to identify 43 genomic regions that influence production of CHCs in both D...

A global outbreak of infections due to Mycobacterium chimaera has been linked to the LivaNova (formerly Sorin) 3 T heater-cooler units (HCUs). We performed a study to investigate M. chimaera from HCUs in China. Water samples were collected from all 3 T HCUs (n = 5) at our hospital in May 2017. Mycobacteria isolates were subjected to genome sequencing using the HiSeq X10 Sequencer. Species were identified based on average nucleotide identity with M. chimaera type strain DSM 44623T . Paired-end reads of all M...

Telomerases are ribonucleoprotein (RNP) enzymes that are related to reverse transcriptases. While they maintain genome stability, their composition varies significantly between species. Yeast telomerase RNPs contain an RNA that is comparatively large and its overall folding shows long helical segments with distal functional parts. Here we investigated the essential stem IVc module of the budding yeast telomerase RNA, called Tlc1. The distal part of stem IVc includes a conserved sequence element CS2a and structurally conserved features to which bind the Pop1/Pop6/Pop7 proteins and which together function analogously to the P3 domains of the RNase P/MRP RNPs...
