an experiment was conducted in algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. serum ca, mg and na levels were significantly high at birth and decreases as the age advanced. the season had a significant effect on the decreased levels of ca, mg and k and inversely on the increased levels of n...

The primary aim of this study was to assay the influence of dietary Ca sources and levels on performance, egg quality indices, and selected blood variables of laying hens. A total of 192 Bovanz commercial layers were distributed to 6 dietary treatment groups with 4 replicates and 8 birds in each replicate. The experimental diets were iso-caloric and iso-nitrogenous, but they were different in t...

Twenty eight term small for gestational age (SGA) infants and 18 term appropriate for gestational age (AGA) infants were studied prospectively to assess bone mineral density and cord serum zinc concentrations. Growth and nutritional status were evaluated, and bone mineral density was measured by dual energy x ray densitometry of the lumbar spine. Cord serum zinc, parathyroid hormone, osteocalci...

Rat osteosarcoma cells respond to 1,25-dihydroxyvitamin D3 with a 6- to 10-fold increase in the secretion of citric acid. The time required to attain a half-maximal response is 12 h, a time course which is consistent with the postulated steroidal hormone action of this vitamin D metabolite. The citrate response is achieved by physiological concentrations of 1,25-dihydroxyvitamin D3, with half o...

Rat osteosarcoma cells respond to 1,25-dihydroxyvitamin D3 with a 6to lo-fold increase in the secretion of citric acid. The time required to attain a half-maximal response is 12 h, a time course which is consistent with the postulated steroidal hormone action of this vitamin D metabolite. The citrate response is achieved by physiological concentrations of 1,25-dihydroxyvitamin Ds, with half of ...

The hybrid Pseudomonas cepacia strain JHR22 was tested for its ability to degrade Aroclor 1221 in soil. The influence of supplements--mineral salts and trace elements--on the degradation was investigated. Disappearance of Aroclor 1221 congeners, occurrence of metabolites, and release of chloride were measured under different conditions. After 45 days the hybrid organism, strain JHR22, was still...

background: leukoplakia is a common, potentially premalignant lesion with malignant transformation rate from 1 to 17% with highest transformation rate for the lesions on the floor of the mouth, soft palate and tongue. one of the main etiological factors is consuming areca nut and its commercial preparations which generate high levels of reactive oxygen species during their metabolism. so the ai...

Ceratocystis coerulescens RWD 451 (Ascomycetes) was cultivated on defined synthetic culture medium containing glucose (3.0% ), asparagine (0.1% ), mineral salts and thiamine. 6 weeks oid cultures produced methyl heptenyl compounds, citronellol. citronellyl acetate, dihydro-farnesol and a hitherto unknown monoterpene alcohol. By GC/MS, 'H and l3C NMR spectroscopy, this alcohol could be identifie...

5-Androstene-3β,7β,17β-triol (β-AET), an active metabolite of dehydroepiandrosterone (DHEA), reversed glucocorticoid (GC)-induced suppression of IL-6, IL-8 and osteoprotegerin production by human osteoblast-like MG-63 cells and promoted osteoblast differentiation of human mesenchymal stem cells (MSCs). In a murine thermal injury model that includes glucocorticoid-induced osteopenia, β-AET signi...
