oxalic/necrosis

Reported similarities in the acute toxic effects of 1,2-dibromo-3-chloropropane (DBCP), 3-chloro-1,2-propaneoxide (epichlorohydrin, ECH), 3-chloro-1,2-propanediol (alphachlorohydrin, ACH), and oxalic acid (OA) have been suggested as presumptive evidence that the metabolism of DBCP to OA, via ECH and

Amphibians in the family Ranidae (true frogs) seem highly susceptible to oxalosis, particularly when fed a diet high in oxalic acid during the premetamorphic (tadpole) stage. The authors describe the mortality of 150 captive-raised wood frogs (Rana sylvatica or Lithobates sylvaticus) from oxalate

American chestnut (Castanea dentata) was transformed with a wheat oxalate oxidase (oxo) gene in an effort to degrade the oxalic acid (OA) secreted by the fungus Cryphonectria parasitica, thus decreasing its virulence. Expression of OxO was examined under two promoters: a strong constitutive

OBJECTIVE To evaluate the efficacy of the OrthoPAT (Haemonetics) system for blood salvage and for removing chemical or cellular debris, by experimental models simulating intra- and postoperative conditions. METHODS Blood samples (20%-25% packed red cells) were prepared for the intraoperative model

Infectious bursal disease in 35-day-old specific-pathogen-free (SPF) chickens was characterized clinically by its acute onset and brief duration. Clinical signs included depression, anorexia, diarrhea, and polyuria. A detectable precipitin antibody response occurred between 3 and 5 days

The biochemical diagnosis of myocardial infarction is based mainly on the enzyme levels of glutamino-oxalic transaminase (SGOT), lactic dehydrogenase (LDH), and creatine-phosphokinase (CPK). The authors have compared the level of phospho-hexo-isomerase (PHI) with the levels of the three other

Acute kidney injury (AKI) is prevalent and is associated with high morbidity and mortality globally. The epidemiology differs remarkably between developing and developed economies. Infections, diarrheal illnesses, obstetric causes and nephrotoxins are very rampant in the tropics. Even though the

Hepatic histologic changes and induction of mixed function oxidases were examined and compared after administration to the chick embryo of four highly purified polychlorinated biphenyl (PCB) congeners: 3,4,3',4'-tetrachlorobiphenyl (TCB) and 3,4,5,3',4',5'-, 2,4,5,2',4',5'-, and

Tomato grey mould has been one of the destructive fungal diseases during tomato production. Ten mM of menadione sodium bisulfite (MSB) was applied to tomato plants for eco-friendly control of the grey mould. MSB-reduced tomato grey mould in the 3rd true leaves was prolonged at least 7 days prior to

Botrytis cinerea is a necrotrophic pathogen that attacks more than 200 plant species. Here, the nonpathogenic mutant A336, obtained via insertional mutagenesis, was characterized. Mutant A336 was nonpathogenic on leaves and fruits, on intact and wounded tissue, while still able to penetrate the host

The star fruit (Averrhoa carambola) is consumed in high amounts in Asia and Central/South America. It contains oxalic acid and caramboxin. In some individuals, its ingestion may lead to nephrotoxicity and neurotoxicity. The nephrotoxic effect is due to oxalate deposition in renal tubules resulting

Ethylene glycol poisoning can produce acute renal failure, requiring long-term hemodialysis to restore function. The mechanism of the renal failure is unknown, but is associated with tubular cell necrosis and ethylene glycol metabolism. The end metabolite of ethylene glycol is oxalic acid, the

High oxalic acid and calcium oxalate (CaOx)-induced renal tubular epithelial cell (TEC) injury plays a key role in nephrolithiasis. However, the mechanism remains unknown. Gene array analysis of the mice nephrolithiasis model indicated significant downregulation of sirtuin 3 (Sirt3) and activation

T2 ribonucleases (RNases) are RNA-degrading enzymes that function in various cellular processes, mostly via RNA metabolism. T2 RNase-encoding genes have been identified in various organisms, from bacteria to mammals, and are most diverse in plants. The existence of T2 RNase genes in almost every
