The Use of 25-hydroxy Vitamin D3 for Meat Poultry
Over a period of time, two vitamin D parent compounds were elucidated. Ergocalciferol (D2) is synthesized from ergosterol in many plants, whereas cholecalciferol (D3) is derived from 7-dehydrocholesterol in the skin of animals. Ultraviolet light transforms these compounds into 1, 25-diOH vitamin D3, the vitamin D metabolite generally considered the most active. Approximately 40 times more D2 is...
متن کاملCorrelation among 25-hydroxy-vitamin D assays.
CONTEXT Measurement of circulating 25-hydroxy-vitamin D [25(OH)D]) is the accepted clinical indicator of vitamin D status. However, between-laboratory differences in measurement of this analyte exist, which may confound clinical care. OBJECTIVES We investigated the current agreement of 25(OH)D measurement in clinical laboratories and explored the possibility that simple calibration would impr...
متن کاملNapping on the night shift among nursing staff: potential benefits for workers' health
Objective: To characterize naps during night shifts in terms of duration, allocation, quality, and sleep efficiency among nursing professionals. Cross-sectional study conducted in 2009. Professionals working the night shift for more than one year and reporting no sleep complaints answered a questionnaire, wore an actigraph (device to monitor human sleep-wake cycle) and completed an activity pro...
متن کاملSerum concentrations of 25-hydroxy vitamin D in Europeans and Asians after oral vitamin D3.
Serum concentrations of 25-hydroxy vitamin D (25-OHD3) were measured in seven Asians of Indian extraction and eight Europeans before and at intervals after taking 1 mg vitamin D3 by mouth. In all subjects the concentrations rose in the 24 hours after ingestion. There was little change over the next nine days in the concentrations in the Europeans but those in the Asians continued to rise until ...
متن کاملIn vitro cellular muscle calcium metabolism. Characterization of effects of 1,25-dihydroxy-vitamin D3 and 25-hydroxy-vitamin D3.
Cultures of vitamin D-deficient chick soleus muscle and 12 day-old chick embryo myoblasts were used to characterize the effects of 1,25-dihydroxy-vitamin D3 and 25-hydroxy-vitamin D3 on muscle cell Ca metabolism. Physiological amounts of both sterols increased the rate and extent of 45Ca uptake by cultures. However, 1,25(OH)2D3 was significantly more effective than 25 OHD3. The greater potency ...
