Evolutionary constraint for insertions and deletions (indels) is not necessarily equal to constraint for nucleotide substitutions for any given region of a genome. Knowing the variation in indel-specific evolutionary rates across the sequence will aid our understanding of evolutionary constraints on indels, and help us infer how indels have contributed to the evolution of the sequence. However, unlike for nucleotide substitutions, there has been no phylogenetic method that can statistically infer significantly different rates of indels across the sequence space independent of substitution rates...

OBJECTIVE: To investigate the antihyperlipidemic, antioxidant, and cytotoxic effect of aqueous and methanol extract of leaves of Polygonum minus. MATERIALS AND METHODS: Acute antihyperlipidemic effect was studied on chemically induced hyperlipidemic rat model. Treated groups received aqueous and methanol extract of leaves of P. minus respectively (1000 mg/kg; oral) whereas standard treated group received atorvastatin (60 mg/kg; oral) for 3 consecutive days. Blood samples were collected at fixed intervals for lipid profile analysis...

BACKGROUND AND AIMS: Lactate levels predict outcomes after hepatectomy. We compared metabolic effects of lactated versus lactate free solutions in living donor hepatectomy. METHODS: Consecutive right lobe donors (n = 53) were alternatively allotted to lactated Ringer's solution and normal saline (Group L-control) or acetated crystalloid (Sterofundin B Braun(®) Group S -study group) in an observational prospective randomised study. The primary outcome measure was lactate level, and secondary outcomes were base excess, bicarbonate, glucose and chloride intra- and post-operatively...

AIM: To compare the composition of the salivary microbiota in caries-affected vs. caries-free mutans streptococci (MS)- positive children with mixed dentition. MATERIALS AND METHODS: Twenty eight healthy, 11-12-year-old schoolchildren with high MS counts (>10⊃5 CFU/mL) were included in this study. The children were screened with the Dentocult SM Strip Mutans test (Orion Diagnostica, Espoo, Finland) and examined using the International Caries Detection and Assessment System (ICDAS)...

At the First WHO Ministerial Conference on Global Action Against Dementia in March, 2015, 160 delegates, including representatives from 80 WHO Member States and four UN agencies, agreed on a call for action to reduce the global burden of dementia by fostering a collective effort to advance research. To drive this effort, we completed a globally representative research prioritisation exercise using an adapted version of the Child Health and Nutrition Research Initiative method. We elicited 863 research questions from 201 participants and consolidated these questions into 59 thematic research avenues, which were scored anonymously by 162 researchers and stakeholders from 39 countries according to five criteria...

Balloon mitral valvotomy (BMV) performed by the conventional transfemoral approach can be difficult or even impossible in the presence of structural impediments such as severe kyphoscoliosis, gross cardiac anatomic distortion and inferior vena caval anomalies. A 25-year-old woman with severe thoracolumbar kyphoscoliosis due to poliomyelitis presented with symptomatic rheumatic mitral valve stenosis. After the failure of transfemoral BMV, the procedure was attempted from the right jugular access, using a modified septal puncture technique...

Identification of new biomarkers for breast cancer remains critical in order to enhance early detection of the disease and improve its prognosis. Towards this end, we performed an untargeted metabolomic analysis of breast ductal fluid using an ultra-performance liquid chromatography coupled with a quadrupole time-of-light (UPLC-QTOF) mass spectrometer. We investigated the metabolomic profiles of breast tumors using ductal fluid samples collected by ductal lavage (DL). We studied fluid from both the affected breasts and the unaffected contralateral breasts (as controls) from 43 women with confirmed unilateral breast cancer...

BACKGROUND: Endovascular treatment of aortoiliac occlusive disease entails the use of multiple stents to reconstruct the aortic bifurcation. Different configurations have been applied and geometric variations exist, as quantified in previous work. Other studies concluded that specific stent geometry seems to affect patency. These variations may affect local flow patterns, resulting in different wall shear stress (WSS) and oscillating shear index (OSI). The aim of this study was to compare the effect of different stent configurations on flow perturbations (recirculation and fluid stasis), WSS, and OSI in an in vitro setup...

The Integrated Microbial Genomes with Microbiome Samples (IMG/M: system contains annotated DNA and RNA sequence data of (i) archaeal, bacterial, eukaryotic and viral genomes from cultured organisms, (ii) single cell genomes (SCG) and genomes from metagenomes (GFM) from uncultured archaea, bacteria and viruses and (iii) metagenomes from environmental, host associated and engineered microbiome samples. Sequence data are generated by DOE's Joint Genome Institute (JGI), submitted by individual scientists, or collected from public sequence data archives...

Chikungunya virus (CHIKV, genus Alphavirus) is the causative agent of chikungunya fever. CHIKV replication can be inhibited by some broad-spectrum antiviral compounds; in contrast there is very little information about compounds specifically inhibiting the enzymatic activities of CHIKV replication proteins. These proteins are translated in the form of a nonstructural (ns) P1234 polyprotein precursor from the CHIKV positive-strand RNA genome. Active forms of replicase enzymes are generated using the autoproteolytic activity of nsP2...

High-affinity, highly specific binding proteins are a key class of molecules used in the development of new affinity chromatography methods. Traditionally, antibody-based methods have relied on the use of immunoglobulins purified from immune animal sera, from egg yolks, or from murine monoclonal hybridoma supernatants. To accelerate and refine the reagent antibody generation process, we have developed optimized methods that allow the rapid assembly of scFv libraries from chickens immunized with pools of immunogens...

Eosinophilic pustular folliculitis or Ofuji's disease is a non-infectious eosinophilic infiltration of hair follicles, which usually presents with itchy papules and pustules in a circinate configuration. We report this case of an immunocompetent patient with erythematous papules and plaques without macropustules diagnosed as eosinophilic pustular folliculitis-a rarely reported entity outside Japan. He was successfully treated with oral dapsone.

Inflammation and angiogenesis play major roles in carotid plaque vulnerability. The purpose of this study was to determine whether gray-scale features of carotid plaques are associated with histologic markers for inflammation. Thirty-eight individuals completed a dedicated research carotid ultrasound exam before carotid endarterectomy. Gray-scale analysis was performed on plaque images to measure plaque echogenicity (gray-scale median [GSM] pixel brightness), plaque area, presence of discrete white areas (DWAs) and the percent of black area near the lumen on any one component of the plaque...
