pyruvic acid/necrosis

Values of various alpha-keto acids in whole blood were determined from cases of cerebrocortical necrosis (CCN), a thiamine deficiency disease, and were compared with those from normal animals. Thiamine pyrophosphate is an essential cofactor in the decarboxylation of many alpha-keto acids and this

Cerebrocortical necrosis was induced through the oral application of amprolium to calves (0.250 g/kg to 1.00 g/kg) and weaned lambs and goats (1.25 g/kg) in the course of 25 to 35 days. In order to shed light on the etiology of the disease an experiment was carried out with a ration rich in

Background: Non-invasive tumor characterization and monitoring are among the key goals of medical imaging. Using hyperpolarized 13C-labelled metabolic probes fast metabolic pathways can be probed in real-time, providing new opportunities for tumor characterization. In this in vitro study, we

Effect of a herbicide, paraquat (1,1'-dimethyl-4,4'-bipyridilium-dichloride), the fungicide copper sulphate, and zinc chloride was studied on the histological structure of liver, kidney and gill of three fish species with different feeding habits, viz.: a herbivorous, silver carp (Hypophthalmichthys

Ethyl pyruvate (EP), a simple aliphatic ester derived from pyruvic acid, improves survival and ameliorates organ system dysfunction in mice with peritonitis induced by caecal ligation and perforation, even when treatment is started as late as 12-24 hours after the onset of sepsis. In studies using

The first instance of familial oculopharyngeal muscular dystrophy (OPMD) affecting a Japanese family is reported. Three patients (a 62-year-old female, her sisters 66-year-old and 53-year-old) were described with suspicious other 2 cases. A 62-year-old woman (case 1) developed bilateral

Acetaminophen, a common analgesic/antipyretic, is a frequent cause of acute liver failure in Western countries. The development of an effective cure against acetaminophen hepatotoxicity is crucial. Ethyl pyruvate, an ethyl ester derivative of pyruvic acid, has been identified as a possible candidate

Ethyl pyruvate (EP) is a simple aliphatic ester derived from the endogenous metabolite, pyruvic acid. EP has been shown to decrease the expression of various pro-inflammatory mediators, including nitric oxide (NO*), tumor necrosis factor (TNF), cyclooxygenase-2, and interleukin (IL)-6, in a variety

BACKGROUND Inflammation response and oxidative stress promote the occurrence and development of multiple-organ dysfunction syndrome (MODS). METHODS Eighty MODS rats with third-degree burns were divided randomly into 4 groups: insulin, ethyl pyruvate (EP), insulin combined with EP, and control. Blood

The repeated intake of a great amount of ethanol is followed by functional and organic changes in the body. The intestinal absorption of alcohol is accompanied by an increased absorption of Gram negative bacteria endotoxins in the portal blood. In the liver, endotoxins stimulate CD14 receptors on

Pyruvic acid, an intermediate metabolite of glucose, an effective scavenger of reactive oxygen species (ROS), inhibits tumor necrosis factor-alpha production and NF-kappaB signaling pathways, reduces circulating levels of HMGB1 (high mobility group B1), decreases COX-2 (cyclo-oxygenase-2), iNOS

Pyruvic acid is an effective scavenger of reactive oxygen species. Ethyl pyruvate has demonstrated anti-inflammatory actions and improved hyperpermeability and bacterial translocation due to endotoxemia and is of benefit in animal models of sepsis and septic shock. Ethyl pyruvate specifically

BACKGROUND Ethyl pyruvate (EP) is a derivative of pyruvic acid that has been demonstrated to be a potential scavenger of reactive oxygen species as well as an anti-inflammatory agent. In this study, we investigated the protective effects of EP and its role in regulating the energy metabolism in the

Heart failure is a disease predominantly caused by an energy metabolic disorder in cardiomyocytes. The present study investigated the inhibitory effects of fenofibrate (FF) on isoproterenol (ISO)‑induced hear failure in rats, and examined the underlying mechanisms. The rats were divided into CON,

Methods for the simultaneous polarization of multiple 13C-enriched metabolites were developed to probe several enzymatic pathways and other physiologic properties in vivo, using a single intravenous bolus. A new method for polarization of 13C sodium bicarbonate suitable for use in patients was
