Cell injury by oxidative stress is an important mechanism for renal epithelial cell destruction. This study observed the protective effect of turmeric and its constituents on H2O2-induced injury. Turmeric consists of a water soluble turmerin and lipid soluble curcumin with potent antioxidant properties. Confluent LLC-PK1 cells were labelled with(More)
Cyclosporin A (CsA) is a cyclic undecapeptide that has been used extensively as an immunosuppressive drug in transplantation medicine and is known to interact with L-arginine dependent pathways. We studied the in vitro and in vivo effects of CsA on nitric oxide synthase (NOS) activity in the rat kidney. CsA in concentrations of 44-2200 nM in vitro, and 12.5(More)
Genes encoding proteins that contain the universal stress protein (USP) domain are known to provide bacteria, archaea, fungi, protozoa, and plants with the ability to respond to a plethora of environmental stresses. Specifically in plants, drought tolerance is a desirable phenotype. However, limited focused and organized functional genomic datasets exist on(More)
We present an epidemiologic study of the cases of cleft lip and cleft palate in Mississippi from 1980 through 1989. Cases were stratified by race (white and nonwhite) but not by association with a major malformation. During this period, a total of 457 new patients with cleft lip or cleft palate were identified from a population of approximately 439,354 live(More)
Arsenic is a toxic metalloid that causes skin cancer and binds to cysteine residues-a property that could be used to infer arsenic responsiveness of a target protein. Non-synonymous Single Nucleotide Polymorphisms (nsSNPs) result in amino acid substitutions and may alter arsenic binding with cysteine residues. Thus, the objective of this investigation was(More)
The overall objective of this study was to determine the role fructose 1,6-diphosphate (FDP), a naturally occurring glycolytic intermediate, plays in activated T-lymphocytes. The hypothesis is twofold. First, we propose that FDP inhibits T cell proliferation to a greater extent than fructose-1-phosphate (F1P), fructose-6-phosphate (F6P) and(More)
BACKGROUND Fructose-1,6-diphosphate (FDP) reduces postischemic reperfusion injury and is used alone and in combination with cyclosporine A (CsA) as an immunosuppressant. METHODS Wistar-Furth rat hearts were grafted to Lewis rats. Activated T-cell proliferation, viability, and interleukin-2 expression were determined. RESULTS Mean survival in days were:(More)
Fructose-1,6-diphosphate (FDP) has a salutary effect on hemorrhagic, traumatic and endotoxic shock. The role of FDP on compound 48/80-induced shock was therefore investigated. Sprague Dawley aged male rats (448+/-7.4 gm body weight) were randomly assigned into three groups and treated intraperitoneally with diphenhydramine (DPHM) 15 mg/kg (n=11), 12.5 ml of(More)
Arsenical keratosis and skin cancer are among the most common health effects associated with acute and chronic exposures to arsenic. This study examines the acute and chronic dose-responses of arsenic in established human cell lines using keratinocytes (HaCaT), melanocytes (CRL1675) and dendritic cells (THP-1 + A23187). Chronic conditions were established(More)
Heterotopic bone formation (HBF), an ill-defined phenomenon, refers to the formation of bone in tissue that normally does not ossify. Two existing theories to explain HBF are that two cellular entities, one from the bone and the other from the muscle or fascia (two cell types) are involved, and that stem cell responds to a factor induced by trauma (one cell(More)
