Cardiac arrhythmias, which occur in a wide variety of conditions where intracellular calcium is increased, have been attributed to the activation of a transient inward current (Iti). Iti is the result of three different [Ca]i-sensitive currents: the Na(+)-Ca2+ exchange current, a Ca(2+)-activated chloride current and a Ca(2+)-activated non-selective(More)
INTRODUCTION Among a range of chloride channels, outwardly rectifying Cl- channels have been reported in the heart of various species. Although the anionic current carried by this channel has been subjected to intense electrophysiological investigations, paradoxically no examination of single-channel currents has been reported for human cardiomyocytes.

PURPOSE Stearoyl-CoA desaturase 1 (SCD1) is a novel therapeutic target in various malignancies, including breast cancer. The present study was designed to investigate the effect of the pharmacologic inhibition of SCD1 on fatty acid composition in tissue explant cultures of human breast cancer and to compare these effects with those in adjacent nonneoplastic(More)
BACKGROUND Aortic valve replacement (AVR) can be performed through a partial upper sternotomy. In this study we compared the early postoperative outcome in two groups of patients who underwent AVR with a minimally invasive procedure (n = 30) or with a conventional approach (n = 70). The predicted operative mortality (Parsonnet Index) was slightly higher in(More)
BACKGROUND Up-regulation of hsp90 gene expression occurs in numerous cancers such as lung cancer. D,L-lactic-co-glycolic acid-poly ethylene glycol-17-dimethylaminoethylamino-17-demethoxy geldanamycin (PLGA-PEG-17DMAG) complexes and free 17-DMAG may inhibit the expression. The purpose of this study was to examine whether nanocapsulating 17DMAG improves the(More)
Introduction : Nowadays, using drug delivery is an essential method to improve cancer therapy through decreasing drug toxicity and increasing efficiency of treatment. Silibinin (C25H22O10), a polyphenolic flavonoid which is isolated from the milk thistle plant, has various applications in cancer therapy but it has hydrophobic structure with low water(More)
Although the deregulated expression of p53R2, a p53-inducible protein and homologue of the R2 subunit of ribonucleotide reductase, has been detected in several human cancers, p53R2 roles in cancer progression and malignancy still remains controversial. In this article, we present a viable hypothesis about the roles of p53R2 in cancer progression and therapy(More)
BACKGROUND HSP90 may be overexpressed in cancer cells which are greatly dependent on Hsp90 function. Geldanamycin derivative 17 allylamino-17-demethoxygeldanamycin (17-AAG) inhibits the function and expression of HSP90. 17-AAG has poor water-solubility which is a potential problem for clinical practice. In this study for improving the stability and(More)
INTRODUCTION Central nervous system (CNS) infections are life-threatening diseases caused by viral, bacterial, parasitic and fungal microorganisms. The aim of this study was to determine the accuracy of universal polymerase chain reaction (PCR) for the detection of bacterial meningitis among patients who were referred to Koodakan Hospital in Bandar Abbas(More)
