Background : Some studies have shown that the serum concentration of 25- hydroxy vitamin D which is represent the status of body vitamin D, has a diverse relationship with obesity status, and the risk of obesity decreases in people with high level of 25- hydroxy vitamin D. The aim of this study is to investigate the correlation between the serum level of 25- hydroxy vitamin D and anthropometric...

For the first time an azo functionality was covalently introduced into a MOF by post-synthetic modification. The reaction of Cr-MIL-101-NH(2) with p-phenylazobenzoylchloride (1) and 4-(phenylazo)phenylisocyanate (2) as the reactants led to the compounds Cr-MIL-101_amide and Cr-MIL-101_urea, with the azo groups protruding into the mesoporous cages. XRPD and N(2) sorption measurements confirm the...

BACKGROUND The modest clothing that Orthodox Jewish women wear exposes very little of their skin to sunlight. Under these conditions they may develop vitamin D deficiency, even in sunny Israel. OBJECTIVES To determine and compare the vitamin D nutritional status in Jewish orthodox mothers to that of non-orthodox mothers who live in the same metropolitan area in Israel. METHODS 25-Hydroxyvit...

We examined the association of vitamin D deficiency to risk of cesarean delivery using prospective data in a cohort of 1153 low income and minority gravidae. Circulating maternal 25-hydroxyvitamin D and intact parathyroid hormone were measured at entry to care 13.73 ± 5.6 weeks (mean ± SD). Intake of vitamin D and calcium was assessed at three time points during pregnancy. Using recent Institut...

In the 1995 National Swine Study of the United States National Animal Health Monitoring System, producers identified respiratory problems as the leading cause of death in pigs during the grower/finisher phase of production. Over a six-month period, 61.7 +/- 4.1% (mean +/- SEM) of operations reported at least one death attributed to respiratory problems among finisher pigs (based on 388 operatio...

BACKGROUND: The degree to which the amount of aningested nutrient is absorbed and available to the body is calledbioavailability. OBJECTIVES: Relative effectiveness of herbalmethionine (H-Met®) compared to DL-methionine (DL-Met)was investigated in this experiment. METHODS: Exponentialregression analysis was used to determine bioefficacy of H-Met®based on body weight gain, feed intake and feed c...

There is a high prevalence of vitamin D deficiency worldwide, but how to define vitamin D deficiency is controversial. Currently, the plasma concentration of total 25-hydroxyvitamin D [25(OH)D] is considered an indicator of vitamin D status. The free hormone hypothesis states that protein-bound hormones are inactive while unbound hormones are free to exert biological activity. The majority of c...
