With-no-lysine kinase 4 (WNK4) and kidney-Specific (KS)-WNK1 regulate ROMK (Kir1.1) channels in a variety of cell models. We now explore the role of WNK4 and KS-WNK1 in regulating ROMK in the native distal convoluted tubule (DCT)/connecting tubule (CNT) by measuring TPNQ (ROMK inhibitor)-sensitive K+ currents with whole-cell recording. TPNQ-sensitive K+ currents in DCT2/CNT of KS-WNK1-/- and WNK4-/- mice were significantly smaller than that of WT mice. In contrast, the basolateral K+ channels (a Kir4.1/5.1 heterotetramer) in the DCT were not inhibited...

PREMISE OF THE STUDY: Diatoms are one of the most species-rich lineages of microbial eukaryotes. Similarities in clade age, species richness, and primary productivity motivate comparisons to angiosperms, whose genomes have been inordinately shaped by whole-genome duplication (WGD). WGDs have been linked to speciation, increased rates of lineage diversification, and identified as a principal driver of angiosperm evolution. We synthesized a large but scattered body of evidence that suggests polyploidy may be common in diatoms as well...

BACKGROUND: Therapeutic variability not explained by patient clinical characteristics is a potential source of avoidable morbidity and mortality. We aimed to explore regional variability in the management and mortality of patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS). METHODS AND RESULTS: 11,931 NSTE-ACS hospital survivors enrolled in two prospective registries: EPICOR [5625 patients, 555 hospitals, 20 countries in Europe (E) and Latin America (LA), September 2010-March 2011] and EPICOR Asia (6306 patients, 218 hospitals, 8 countries, June 2011-May 2012) were compared among eight pre-defined regions: Northern E (NE), Southern E (SE), Eastern E (EE); Latin America (LA); China (CN), India (IN), South-East Asia (SA), and South Korea, Hong Kong and Singapore (KS)...

We report a general strategy for obtaining high-quality, large-area metal-chalcogenide semiconductor films from precursors combining chelated metal salts with chalcoureas or chalcoamides. Using conventional organic solvents, such precursors enable the expeditious formation of chalco-gels, which are easily transformed into the corresponding high-performance metal-chalcogenide thin films with large, uniform areas. Diverse metal chalcogenides and their alloys (MQ x : M = Zn, Cd, In, Sb, Pb; Q = S, Se, Te) are successfully synthesized at relatively low processing temperatures (<400°C)...

As an important glycosaminoglycan, keratan sulfate (KS) mainly exists in corneal and cartilage, possessing various biological activities. In this study, we purified KS from blue shark ( Prionace glauca ) cartilage and prepared KS oligosaccharides (KSO) through keratanase II-catalyzed hydrolysis. The structures of KS and KSO were characterized using multi-dimensional nuclear magnetic resonance (NMR) spectra and liquid chromatography-mass spectrometry (LC-MS). Shark cartilage KS was highly sulfated and modified with ~2...

BACKGROUND: Serum protein acidic and rich in cysteine (SPARC) is a matricellular glycoprotein, which regulates cell proliferation and facilitates intracellular transport of albumin bound particles including chemotherapeutic agents such as Nab-paclitaxel/ABI-007. Therefore the presence of SPARC may achieve higher intra-tumoral drug concentration with lower dosage and thus reduce systemic side-effects. Several trials of ABI-007, in melanoma, show promising clinical activity. DESIGN: Fifty-four cases of dermal based neoplasms were retrieved including 24 angiosarcomas (AS), 10 hemangiomas, 9 nodular melanomas, 4 Kaposi sarcomas (KS), 3 leiomyosarcomas (LMS), 3 atypical fibroxanthomas (AFX) and 1 spindle cell squamous cell carcinoma (SSCC)...

Ancylostoma ceylanicum may inhabit the small intestine of canids, felids and humans, can pose a potential risk to public health. This study is the first time to amplify complete mitochondrial genome sequence of A. ceylanicum from dog and to compare it with Ancylostoma tubaeforme, Ancylostoma duodenale and Ancylostoma caninum. The results showed that the complete mitochondrial genome of A. ceylanicum was 13,660 bp in length, including 12 protein-coding genes, 2 rRNA genes and 22 tRNA genes and 3 non-coding regions (AT-rich region, SNCR and LNCR)...

Ka Un Lao, John M Herbert
We report an implementation of extended symmetry-adapted perturbation theory (XSAPT) in the atomic orbital basis, extending this method to systems where the monomers are large. In our "XSAPT(KS)" approach, monomers are described using range-separated Kohn-Sham (KS) density functionals whose asymptotic behavior is set by tuning the range-separation parameter, ω, in a monomer-specific way. This is accomplished either by conventional ionization potential (IP)-based tuning, in which ω is adjusted to satisfy the condition εHOMO (ω) = -IP(ω), or else using a so-called "global density-dependent" (GDD) condition, in which ω is fixed based on the size of the exchange hole...

Melatonin is a pleiotropic molecule with various important physiological roles in vertebrates. l-aromatic amino acid decarboxylase (AAAD) is the second enzyme for melatonin synthesis. By far, a clear-cut gene function of AAAD in the biosynthesis of melatonin has been unclear in vertebrates. Here, we provide novel insights into the evolution of AAAD based on 77 vertebrate genomes. According to our genome-wide alignments, we extracted a total of 151 aaad nucleotide sequences. A phylogenetic tree was constructed on the basis of these sequences and corresponding protein alignments, indicating that tetrapods and diploid bony fish genomes contained one aaad gene and a new aaad -like gene, which formed a novel AAAD family...

Hyperbaric oxygen therapy is widely accepted as life-saving treatment for decompression illness. Yet its use in acute carbon monoxide poisoning has remained controversial because of inconsistent findings in clinical trials. Hyperbaric oxygen therapy has an adjunctive role in managing gas gangrene, necrotising soft-tissue infection, and crush injury, as supported by case series. Several cases have been reported in the literature detailing the use of hyperbaric oxygen therapy in patients with severe anaemia in whom blood transfusion is not possible...

Kallmann syndrome (KS) is a rare clinical and genetic heterogeneity disease, which is familial or sporadic. KS is known to have three patterns of inheritance: X linked recessive inheritance, autosomal dominant inheritance and rare autosomal recessive inheritance. Here, we report a sibling pedigree with autosomal dominant inheritance of KS, and we identified a novel heterozygous frameshift mutation c.299_300insCCGCAGACTCCGGCCTCTATGC (p.C101Rfs*17) in FGFR1 gene using whole-exome sequencing (WES). The mutation and affection status were cosegregated...

Although the relationship between Kaposi's sarcoma (KS) and renal transplant has been well described, there are rare cases of KS concurrent with membranous glomerulonephritis or other glomerular diseases. In this report, a patient with membranous glomerulonephritis that accepted long-term prednisolone and cyclosporine immunosuppressive therapy developed skin KS. Withdrawal of immunosuppressive treatment resulted in the disappearance of KS.

Weaning may be associated with negative energy balance and body weight loss when calves are still immunologically immature, predisposing them to infectious diseases. The aim of the present experiment was to investigate the effects of treatment of preweaning dairy calves with recombinant bovine somatotropin (rbST) on the somatotropic axis, selected immune parameters, and hematology of calves around weaning. Thirty-six Holstein female calves were randomly assigned to receive 1.5 to 1.8 mg of rbST (Posilac, Elanco Animal Health, Greenfield, IN) per kilogram of body weight or to receive injections of saline (saline solution 0...

Chiral pesticides are often degraded enantioselectively in soils, leading to disparity among enantiomers that may display different toxicity levels. Monitoring pesticide degradation extents and processes remains out of reach in the field using conventional bulk and enantiomer concentration analyses. Enantioselective stable carbon isotope analysis (ESIA) combines compound specific isotope analysis (CSIA) and enantioselective analysis, and bears potential to distinguish enantiomer degradation from non-destructive dissipation...

Saperda populnea is a serious pest of poplar and willow trees in the Palaearctic region, causing extensive damage to forests and the lumber industry. Until recently, there is no safe and effective chemical method to control this pest due to the lack of sufficient knowledge on the molecular basis of its olfactory genes, moreover, the evolutionary history of the olfactory gene family in subfamily Lamiinae is still fully unknown. Our RNA sequencing of the antennae of S. populnea identified 43 odorant binding proteins (OBPs), 15 chemosensory proteins (CSPs), 56 odorant receptors (ORs) and 24 inotropic receptors (IRs) in S...

Purpose: Synthesis of keratan sulfate (KS) relies on coordinated action of multiple enzymes, including the N-acetylglucosamine-transferring enzyme, β-1,3-N-acetylglucosaminyltransferase-7 (β3GnT7). A mouse model deficient in β3GnT7 was developed to explore structural changes in KS and the extracellular matrix (ECM; i.e., the corneal stroma), elucidate the KS biosynthesis mechanism, and understand its role in corneal organization. Methods: A knockout vector for the β3GnT7-encoding gene, B3gnt7, was created to develop heterozygous- (htz) and homozygous-null (null) knockouts...

Self-interaction error (SIE) is considered to be one of the major sources of error in most approximate exchange-correlation functionals for Kohn-Sham density-functional theory (KS-DFT), and it is large with all local exchange-correlation functionals and with some hybrid functionals. In this work, we demonstrate that by using multiconfiguration pair-density functional theory (MC-PDFT), the SIE of a translated local density-functional approximation is significantly reduced (by a factor of 3) when using an MCSCF density and on-top density, as compared to using KS-DFT with the parent functional; and the SIE in MC-PDFT with local on-top functionals is even lower than in some popular KS-DFT hybrid functionals...

Reactive oxygen species (ROS) are versatile signaling molecules in sensing stresses and play critical roles in signaling and development. Plasma membrane NADPH oxidases (NOXs) are key producers of ROS, and play important roles in the regulation of plant-pathogen interactions. Here, we performed a comprehensive analysis of the NOX gene family in the soybean genome (Glycine max) and 17 NOX (GmNOX) genes were identified. Structural analysis revealed that the GmNOX proteins in soybean were as conserved as those in other plants...
