A humoral factor has been implicated in Dahl salt-sensitive genetically hypertensive rats. The goal of this study was to evaluate the pressor role of vasopressin (AVP) in Dahl rats. Salt-sensitive (S) and resistant (R) rats were fed either high (8%) or low (.04%) NaCl diets for 6 to 8 weeks. Blood pressure was elevated in S rats fed high salt diets (p less than 0.05). Plasma AVP increased with ...

iranian farmers are faced with many challenges. they must be economically efficient, produce enough food for the growing population and must be sensitive to environmental concerns. however, there is a growing concern related to the aftermath and side-effect of some agricultural activities on environment. these concerns made researches to consider agricultural activities with profound care in or...

Aberrant crypt foci (ACF) are putative preneoplastic lesions of colon cancer which are being utilized currently as a biological end point to evaluate the induction and modulation of colon carcinogenesis. In several previous short-term studies, the unexpected reduction of ACF by the reported colonic tumor promoter cholic acid (CHA) emphasized the need for a systematic evaluation of the growth of...

Sarcocystis sporocysts were found in intestinal scrapings from 24 (54.5%) of 44 opossums (Didelphis virginiana). The number of sporocysts varied from a few (< 10,000) to 245 million. Sporocysts from 23 of 24 opossums were fed to captive budgerigars (Melopsittacus undulatas), and the inocula from 21 opossums were infective, indicating the presence of Sarcocystis falcatula. Sporocysts from 24 opo...

PURPOSE To investigate the differential expression of the glycoprotein clusterin/apoJ (CLU) in normal and Fuchs' endothelial dystrophy (FED) corneal endothelium and to compare the expression of various forms of CLU in normal and FED tissue. METHODS FED and pseudophakic bullous keratopathy (PBK) corneal buttons were removed during transplantation, and normal corneas were obtained from tissue b...

The objective of this study was to test whether the gastrointestinal tolerance of a new infant formula equalled or exceeded the tolerance of other milk-based infant formulas, and to compare the tolerance of the new formula to that of human milk. This prospective, observational, multicenter, open-label study was conducted in Taiwan. Healthy, full-term infants aged 28-98 days were enrolled on the...

insulin resistance syndrome, also referred to as the metabolic syndrome or syndrome x, refers to a constellation of common metabolic and cardiovascular disorders (e.g. obesity, type 2 diabetes mellitus, hypertension, and dyslipidemia), which are all cardiovascular risk factors. insulin resistance can be induced by fructose-rich diet in rats. we investigated the effect of vanadyl sulfate (0.2 mg...

Between 6% and 11% of the world's population suffers from malnutrition or undernutrition associated with poverty, aging or long-term hospitalization. The present work examined the effect of different types of proteins on the mechanistic target of rapamycin (mTORC1)-signaling pathway in: (1) healthy; and (2) protein restricted rats. (1) In total, 200 rats were divided into eight groups and fed o...
