To determine whether the major human malaria parasite Plasmodium falciparum exhibits fragmented population structure or local adaptation at the northern limit of its African distribution where the dry Sahel zone meets the Sahara, samples were collected from diverse locations within Mauritania over a range of ~ 1000 kilometres. Microsatellite genotypes were obtained for 203 clinical infection samples from eight locations, and Illumina paired-end sequences were obtained to yield high coverage genome-wide single nucleotide polymorphism (SNP) data for 65 clinical infection samples from four locations...

Mayaro virus (MAYV) is an arthropod-borne virus and a member of the family Togaviridae, genus Alphavirus. Its infection leads to an acute illness accompanied by long-lasting arthralgia. To date, there are no antiviral drugs or vaccines against infection with MAYV and resources for the prevention or treatment of other alphaviruses are very limited. MAYV has served as a model to study the antiviral potential of several substances on alphavirus replication. In this work we evaluated the antiviral effect of seven new derivatives of thieno[2,3-b]pyridine against MAYV replication in a mammalian cell line...

REVIEW
John E Kehoe, Matthew S Christman
PURPOSE OF REVIEW: Testicular remnants or nubbins are commonly found in the evaluation and treatment of cryptorchidism. While much debate focuses on the management of the nubbin itself, there is also great uncertainty and variation in the management of the contralateral descended testis. Herein, we review the relevant literature informing the decision to perform a contralateral orchiopexy. RECENT FINDINGS: Although there is very little recent literature directly addressing the question, some studies have better characterized differences in practice, the risk of intravaginal torsion in the contralateral testis and potential consequences in the selection of technique...

The state of Assam in north-east India gained popularity in Asia because of discovery of oil. Pollution due to petroleum and gas exploration is a serious problem in Assam. Oil and gas exploration by various agencies in Assam resulted in soil pollution due to hydrocarbons (HCs) and heavy metals (HMs). Bioremediation gained considerable significance in addressing petroleum hydrocarbon polluted sites in various parts of the world. In this investigation, we have observed 15 species of plants belonging to grass growing on the contaminated soils...

BACKGROUND: Digital health social networks (DHSNs) are widespread, and the consensus is that they contribute to wellness by offering social support and knowledge sharing. The success of a DHSN is based on the number of participants and their consistent creation of externalities through the generation of new content. To promote network growth, it would be helpful to identify characteristics of superusers or actors who create value by generating positive network externalities. OBJECTIVE: The aim of the study was to investigate the feasibility of developing predictive models that identify potential superusers in real time...

To assure water safety and protect human health, precise and simple analytical approaches are highly desired to determine low concentrations of microcystin-leucine-arginine (MC-LR), a toxin, in both water and serum samples. Herein, a simple, rapid and accurate aptamer-based fluorescent sensor was used for selective recognition of MC-LR, based on single-walled carbon nanotubes (SWNTs) as immobilizers, dapoxyl as a fluorescent dye, DAP-10 as a specific aptamer for dapoxyl and unmodified MC-LR aptamer (Apt) as a sensing ligand...

Boronic acid modified materials have been widely used to adsorb nucleosides, but their adsorption capacities require further improvement. Most cis-diol containing biomolecules are in very low abundance along with interfering components in real samples, and need to be enriched specially. In this study, we synthesize a kind of silica absorbent modified with boronic acid derivative, using amorphous silica as raw material and obtaining high adsorption capacity for adenosine. In addition, the adsorption equilibrium can be completed within 10s and 1min for the desorption...

REVIEW
Kai P Law, Hua Zhang
Gestational diabetes mellitus (GDM) is a form of diabetes that is first recognised during pregnancy, with no evidence of pre-existing type 1 or type 2 diabetes. The prevalence of GDM has been rising steadily over the past few decades, coinciding with the ongoing epidemic of obesity and type 2 diabetes. Although GDM normally disappears after delivery, women who have been previously diagnosed with GDM are at a greater risk of developing gestational diabetes in subsequent pregnancies, and type 2 diabetes later in life...

Current antiepileptic drugs have limited efficacy and provide little or no benefits in 30% of the patients. Given that a role for brain inflammation in epilepsy has been repeatedly reported in recent years, the potential of anti-inflammatory drugs should be explored in depth, as they may provide new therapeutical approaches in preventing or reducing epileptogenesis. Here, we review preclinical (both in vivo and in vitro) and clinical epilepsy studies in which nonsteroidal antiinflammatory drugs (NSAIDs), i...

The RNA helicase DEAD-box protein Sub2 (yeast)/UAP56 (mammals) is conserved across eukaryotes and is essential for mRNA export in trypanosomes. Despite the high conservation of Sub2 in lower eukaryotes such as Trypanosoma cruzi, the low conservation of other mRNA export factors raises questions regarding whether the mode of action of TcSub2 is similar to that of orthologs from other eukaryotes. Mutation of the conserved K87 residue of TcSub2 abolishes ATPase activity, showing that its ATPase domain is functional...

BACKGROUND: A method is outlined for the use of an individual-based stochastic model of parasite transmission dynamics to assess different designs for a cluster randomized trial in which mass drug administration (MDA) is employed in attempts to eliminate the transmission of soil-transmitted helminths (STH) in defined geographic locations. The hypothesis to be tested is: Can MDA alone interrupt the transmission of STH species in defined settings? Clustering is at a village level and the choice of clusters of villages is stratified by transmission intensity (low, medium and high) and parasite species mix (either Ascaris, Trichuris or hookworm dominant)...

Active cellular transporters of harmful agents-multidrug resistance (mdr) proteins-are present in tumor, stem and endothelial cells, among others. While mdr proteins are broadly studied in tumor cells, their role in non-tumor cells and the significance of their action not connected with removal of harmful xenobiotics is less extensively documented. Proper assessment of mdr proteins expression is difficult. Mdr mRNA presence is most often evaluated but that does not necessarily correlate with the protein level...

T97A is an HIV-1 integrase polymorphism associated with integrase strand transfer inhibitor (INSTI) resistance. Using pooled data from 16 clinical studies, we investigated the prevalence of T97A (pre-existing and emergent) and its impact on INSTI susceptibility and treatment response in INSTI-naive patients who enrolled on elvitegravir (EVG)- or raltegravir (RAL)-based regimens. Prior to INSTI-based therapy, primary INSTI resistance-associated mutations (RAMs) were absent and T97A pre-existed infrequently (1...
