Mechanical stretch and oxidative stress have been shown to prolong action potential duration (APD) and produce early afterdepolarizations (EADs). Here, we developed a simulation model to study the role of stretch-activated channel (SAC) currents in triggering EADs in ventricular myocytes under oxidative stress. We adapted our coupling clamp circuit so that a model ionic current representing the...

The application of carbonaceous adsorbents in medicine has old traditions. Still antique doctors used charcoal for treatment of wounds. To the beginning of ?? century the therapeutic use range of active carbons (? C) essentially has extended as an outside means (treatment of purulent wounds and ulcers, disinfecting in surgical and dental surgery practice), and internal adsorption preparation (e...

S-allylcysteine (SAC) is an organosulfur-containing compound derived from garlic. Studies have shown that garlic is beneficial in the treatment of cardiovascular diseases. This study aims to elucidate if SAC is responsible for this cardioprotection using acute myocardial infarction (AMI) rat models. In addition, we hypothesized that SAC may mediate cardioprotection via a hydrogen sulfide (H(2)S...

INTRODUCTION Dirofilariasis is a rare parasitic infestation in humans. CASE A 33-year-old female from the coastal area presented with a swelling over the right lacrimal sac area. It was clinically diagnosed as a lacrimal abscess and was incised under local anaesthesia. A live coiled worm was found and removed along with the cyst. OBSERVATIONS The worm looked like a thin white thread measuri...

PURPOSE The purpose of this study was to investigate the prevalence of a common canalicular entrance in the lacrimal sac and to investigate the anatomy of the canalicular/lacrimal sac junction with direct visualization using a novel cadaveric dissection technique. METHODS Preserved cadavers were dissected to allow direct visualization of the canalicular entrance(s) to the lumen of the lacrima...

conclusions the results of the present investigation suggest that sac could be used as a food supplement in the treatment of diabetes characterized by provoked antioxidant status, altered blood glucose, and hormones level. results the levels of glucose, cyp2e1 activity, thiobarbituric acid reactive substances (tbars), hydroperoxide, and ceruloplasmin were increased significantly; whereas, the l...

S-allyl cysteine (SAC) is the most abundant compound in aged garlic extracts (AGEs). AGE has been reported to ameliorate the oxidative damage implicated in a variety of diseases. However, the effects of SAC have not been established in liver cirrhosis. The aim of this study was to examine the effect of therapeutic administration of SAC in liver cirrhosis by chronic carbon tetrachloride (CCl4) a...

The murine yolk sac, being the first site of embryonic blood cell production, has long been theorized to contain the migrating hematopoietic stem cells (HSC) that seed the liver and initiate hematopoiesis on day 10.0 postcoitus (pc). However, it remains controversial whether yolk sac cells isolated before day 11.0 pc possess any long-term repopulating HSC activity upon transplantation into adul...
