Extracellular Histones as Exosome Membrane Proteins Regulated by Cell Stress.

Histones are conserved nuclear proteins that function as part of the nucleosome in the regulation of chromatin structure and gene expression. Interestingly, extracellular histones populate biofluids from healthy individuals, and when elevated, may contribute to various acute and chronic diseases. It is generally assumed that most extracellular histones exist as nucleosomes, as components of extracellular chromatin.

Incidence and Performance of Spinouts and Incumbent New Establishments: Role of Selection and Redeployability within Parent Firms.

Research Summary: Using matched employer-employee data from 30 U.S. states covering a wide range of industries, we compare spinouts with new establishments formed by incumbents (INEs).

A Randomized Controlled Trial Comparing the Effect of Phenylephrine by Intramuscular Route With Intravenous Infusion in Maintaining Haemodynamic Stability During Elective Lower Segment Caesarean Section Under Spinal Anaesthesia.

Background Hypotension is a commonly encountered side effect in patients undergoing spinal anaesthesia, particularly in patients undergoing caesarean section. Phenylephrine is a widely used drug to treat spinal-induced hypotension and to maintain hemodynamic stability. Our aim is to evaluate the effectiveness of phenylephrine given through two different routes prophylactically in prevention of post-spinal hypotension in patients undergoing caesarean section.

Patient Comfort During Postop Period in Breast Cancer Surgeries: A Randomized Controlled Trial Comparing Opioid and Opioid-Free Anesthesia.

Background: Anesthetic management practices have advanced to opioid-free anesthesia (OFA) often replacing opioids in oncologic surgeries. The study was conducted to find the quality of recovery (QoR) of patients undergoing breast cancer surgeries receiving OFA.

Methods: A double-blinded, randomized controlled study was conducted with 60 patients randomized to group OFA and group OA (opioid anesthesia).

Enhanced Photocatalytic Activity of CuO Cabbage/RGO Nanocomposites under Visible Light Irradiation.

Towards the utilization of CuO nanomaterial for the degradation of industrial dye pollutants such as methylene blue and methyl orange, the graphene-incorporated CuO nanocomposites (GCC) were developed via a precipitation method. Using Hummers method, the grapheme oxide (GO) was initially synthesized. The varying weight percentages (1-4 wt %) of GO was incorporated along with the precipitation of CuO catalyst.

ENPL-1, the homolog of GRP94, promotes insulin secretion via regulation of proinsulin processing and maturation.

Insulin/IGF signaling in is crucial for proper development of the dauer larva and growth control. Mutants disturbing insulin processing, secretion and downstream signaling perturb this process and have helped identify genes that affect progression of type 2 diabetes. Insulin maturation is required for its proper secretion by pancreatic β cells.

Depletion of the ER chaperone ENPL-1 sensitizes C. elegans to the anticancer drug cisplatin.

Cisplatin is an essential chemotherapeutic drug in the treatment of many cancers. Its use, however, is limited by the development of resistance in many tumors. The ability to re-sensitize resistant tumors could significantly strengthen cisplatin therapy in patients.

Macroeconomic environment during infancy as a possible risk factor for adolescent behavioral problems.

CONTEXT Economic difficulties at the individual level can lead to a number of behavioral problems, including substance abuse and delinquent behaviors. OBJECTIVE To examine the influence of a nationwide adverse economic environment during infancy, specifically, the high unemployment rates during and after the 1980 and 1981-1982 recessions, on rates of subsequent adolescent substance use and delinquent behaviors. DESIGN We used data from the National Longitudinal Survey of Youth 1997 and estimated logit regressions to examine the effect of changes in unemployment rates during infancy on the incidence of adolescent behavioral problems, controlling for known youth, family, and environmental risk factors.

A directed RNAi screen based on larval growth arrest reveals new modifiers of C. elegans insulin signaling.

Genes regulating Caenorhabditis elegans insulin/IGF signaling (IIS) have largely been identified on the basis of their involvement in dauer development or longevity. A third IIS phenotype is the first larval stage (L1) diapause, which is also influenced by asna-1, a regulator of DAF-28/insulin secretion. We reasoned that new regulators of IIS strength might be identified in screens based on the L1 diapause and the asna-1 phenotype.

Utilisation of Agriculture Weed for the Removal of Cr(VI) from Aqueous Solution.

The present study investigates the potential use of activated carbon prepared from Cassia tora by sulphuric acid treatment for the removal of Chromium(VI) from aqueous solution. The effects of pH, initial concentration, contact time, and carbon concentration were studied for the sorption of Cr(VI) in batch mode. The optimum pH value for Cr(VI) adsorption was determined as 2.

Isolation of a single-stranded DNA-binding protein from the methylotrophic yeast, Pichia pastoris and its identification as zeta crystallin.

A single-stranded DNA (ssDNA)-binding protein (SSB) that binds to specific upstream sequences of alcohol oxidase (AOX1) promoter of the methylotrophic yeast Pichia pastoris has been isolated and identified as zeta crystallin (ZTA1). The cDNA encoding P.pastoris ZTA1 (PpZTA1) was cloned into an Escherichia coli expression vector, the recombinant PpZTA1 was expressed and purified from E.

Differential developmental regulation of rat liver canalicular membrane transporters Bsep and Mrp2.

Bile formation depends on the active secretion of bile salts and other biliary constituents by specific transporters. Recently two major transporters that contribute to bile formation, the bile salt export pump (Bsep) and multidrug resistance protein-2 (Mrp2), have been cloned. The goal of the present study was to define the expression of Bsep and Mrp2 during rat liver development.
