Serum 25-hydroxyvitamin D levels in thalassaemia. [PDF]

Archives of Disease in Childhood, 1978
Serum 25-hydroxyvitamin D levels were measured in 36 thalassaemic children and 27 controls aged 5-15 years. Blood specimens were collected from the beginning of April until the end of October 1976. We considered as the winter period the first 3 months and the summer period the last 4 months.

25-Hydroxyvitamin D and Severity of Parkinson’s Disease [PDF]

International Journal of Endocrinology, 2013
Introduction. A role for vitamin D deficiency in Parkinson’s disease (PD) has recently been proposed. Given the growing body of evidence for the association of vitamin D with several neurodegenerative disorders and unavailability of any published study in the Middle East, the present study is aimed to determine the associations of circulating 25 ...

Association Between Genetically Predicted 25-Hydroxyvitamin D and Type 2 Diabetes Risk in South Asians: An Exploratory Two-Sample Mendelian Randomization Study. [PDF]

Endocrinol Diabetes Metab
Using two‐sample Mendelian randomization, we found no statistically significant association between genetically predicted 25‐hydroxyvitamin D and Type 2 diabetes risk in South Asians. However, the limited exposure GWAS, three‐instrument set, exploratory instrument threshold, and possible sample overlap warrant cautious interpretation and larger South ...

Vitamin D receptor ChIP-seq in primary CD4+ cells: relationship to serum 25-hydroxyvitamin D levels and autoimmune disease. [PDF]

, 2013
BACKGROUND: Vitamin D insufficiency has been implicated in autoimmunity. ChIP-seq experiments using immune cell lines have shown that vitamin D receptor (VDR) binding sites are enriched near regions of the genome associated with autoimmune diseases.

25-Hydroxyvitamin D in Plasma of Cattle

Journal of Dairy Science, 1979
Blood samples from 12 Shorthorn heifers, fed a grass silage ration and housed indoors or outdoors, were assayed for 25-hydroxyvitamin D during 9 mo. There was more in plasma during the summer from the outdoor group, reflecting a greater exposure to ultraviolet light and dermal synthesis of vitamin D, the precursor of 25-hydroxyvitamin D.

25-Hydroxyvitamin D: A Difficult Analyte [PDF]

Clinical Chemistry, 2012
In their article in the current issue of Clinical Chemistry , Farrell et al. (1) describe the latest in a number of studies (2, 3) highlighting the method-related variability in serum 25-hydroxyvitamin D (25-OHD)2 results. There is common agreement that 25-OHD is a “difficult” analyte.
