BACKGROUND Ursolic acid (UA), a pentacyclic triterpenoid carboxylic acid, is the major component of many plants including apples, basil, cranberries, peppermint, rosemary, oregano and prunes and has been reported to possess antioxidant and anti-tumor properties. These properties of UA have been attributed to its ability to suppress NF-κB (nuclear factor(More)
Stem cells are primitive cells that can differentiate and regenerate organs in different parts of the body such as heart, bones, muscles and nervous system. This has been a field of great clinical interest with immense possibilities of using the stem cells in regeneration of human organ those are damaged due to disease, developmental defects and accident.(More)
BACKGROUND Atherosclerosis is a progressive disease characterized by the accumulation of lipids and fibrous elements in the large arteries which now has become the pre-eminent health problem worldwide. OBJECTIVES To investigate the effect and mechanism of Losartan intervention on atherosclerosis in rabbits fed with high-cholesterol diet. MATERIALS AND(More)
The microbial community structure of a stable pilot-scale thermophilic continuous stirred tank reactor digester stabilized on poultry litter was investigated. This 40-m3 digester produced biogas with 57 % methane, and chemical oxygen demand removal of 54 %. Bacterial and archaeal diversity were examined using both cloning and pyrosequencing that targeted(More)
Genome-wide association studies have revealed that many low-penetrance breast cancer susceptibility loci are located in non-protein coding genomic regions; however, few have been characterized. In a comparative genetics approach to model such loci in a rat breast cancer model, we previously identified the mammary carcinoma susceptibility locus Mcs1a. We now(More)
Prolonged oxidative stress favors tumorigenic environment and inflammation. Oxidative stress may trigger redox adaptation mechanism(s) in tumor cells but not normal cells. This may increase levels of intracellular antioxidants and establish a new redox homeostasis. Nrf-2, a master regulator of battery of antioxidant genes is constitutively activated in many(More)
The objectives of the present investigation are (1) to screen the liquid and solid polyethylene glycol (PEG) molecules able to produce microparticles by cold or hot dispersion method either with or without other excipients, and (2) to evaluate the in vitro activities [like thermodegradation at three different storage conditions, dissolution using a(More)
Rat mammary carcinogenesis models have been used extensively to study breast cancer initiation, progression, prevention, and intervention. Nevertheless, quantitative molecular data on epithelial cell differentiation in mammary glands of untreated and carcinogen-exposed rats is limited. Here, we describe the characterization of rat mammary epithelial cells(More)
OBJECTIVE This study was performed to determine the occurrence of hypoxic hepatitis in full-term neonates after perinatal asphyxia and to correlate between the rise in enzymes and severity of asphyxia with Apgar score and hypoxic ischemic encephalopathy (HIE) grading of the neonates. METHOD AND MATERIAL This prospective case-controlled study was conducted(More)
The ectodermal dysplasias (EDs) are a large and complex group of diseases. More than 170 different clinical conditions have been recognized and defined as ectodermal dysplasias. Commonly involved ectodermal-derived structures are hair, teeth, nails, and sweat glands. In some conditions, it may be associated with mental retardation. We report a case of(More)
