In this research, we investigated the cytotoxic mechanisms of Cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.This micro algae is responsible for a severe and widespread harmful algal bloom in the Persian Gulf and Gulf of Oman (2008-2009). Isolated hepatocytes were obtained by collagenase perfusion of Sprague-Dawley rat liver.According to our results, incubation of algal...

We seek to understand patterns that form due to acute inflammation in the skin in the absence of specific pathogenic stimuli. By incorporating inhibition (represented by an anti-inflammatory cytokine) into a classical Keller–Segel chemotaxis model, we create a novel model that produces a variety of spatial patterns. We find that the dynamical instability in both homogeneous and nonhomogeneous s...

A heat-stable protein has been detected in Saccharomyces cerevisiae which inhibits mitochondrial ATPase activity. The protein inhibitor has been isolated from extracts prepared by brief heat treatment of unbroken cell suspensions. The isolated inhibitor is a small basic protein (molecular weight close to 7000, isoelectric proint 9.05) devoid of tryptophan, tyrosine, and cysteine as well as prol...

α-galycoceramide (α-galcer) or the common name of krn7000 is an α-gelasphin derivative. the α-galcer structure consists of a galactose combined with a ceramide in an α-configuration. social isolation (si) has been linked with enhanced inflammation, through modifications in transcriptional pathways linked with glucocorticoid, to stress. our hypothesis is to investigate mediatory role of glucocor...

A new D-glucose-6-phosphate phosphohydrolase (G6Pase) inhibitor, CJ-21,164 (1) was isolated from the fermentation broth of the fungus Chloridium sp. CL48903. The structure was elucidated to be a novel tetramer of the salicylic acid derivatives by spectroscopic analyses. Compound I inhibited G6Pase in rat liver microsomes with an IC50 of 1.6 microM. Glucose output from hepatocytes isolated from ...

Objective(s): Reperfusion of ischaemic myocardium results in reduced nitric oxide (NO) biosynthesis by endothelial nitric oxide synthase (eNOS) leading to endothelial dysfunction and subsequent tissue damage. Impaired NO biosynthesis may be partly due to increased levels of asymmetrical dimethylarginine (ADMA), an endogenous inhibitor of eNOS. As dimethylarginine dimet...

A 42-year-old woman presents with abdominal pain after taking her first dose of lisinopril. Visceral angioedema was diagnosed based on clinical suspicion and abdominal computed tomography (CT). Awareness of this rare side effect of a common medication is key to avoid delays in diagnosis and unnecessary procedures.

Abstract Systems of activator–inhibitor reaction–diffusion equations posed on an infinite line are studied using a variety analytical and numerical methods. A canonical form is considered, which contains all known models with simple cubic autocatalytic nonlinearity arbitrary constant linear kinetics. Restricting attention to that have unique homogeneous equilibrium, this class includes the clas...

nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. the mild steels were pretreated electrochemically to modify the mild steel surface. the modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...

abstract nowadays, bypassing agents such as recombinant activated factor vii (rfviia) and activated prothrombin complex concentrates (apcc) are used to treat bleeding episodes in the hemophilia patients with inhibitors. aryoseven® is an iranian biogeneric rfviia with homogeneity of efficacy and the nature to novoseven in a comparative trial. the current clinical trial aimed to evaluate the cost...
