Association between physical activity and the utilization of general practitioners in different age groups.

Background: Physical activity (PA) is an important tool in health promotion, prevention, curation, and rehabilitation and should be part of general practitioners (GP) consultations. For tailoring GP's service it is important to know the PA habits of the clients.

Methods: Data from the Austrian Health Interview Survey 2014 with 15,770 subjects were analyzed.

Primary vitamin D receptor target genes as biomarkers for the vitamin D3 status in the hematopoietic system.

Vitamin D(3) belongs to the few nutritional compounds that has, via the binding of its metabolite 1α,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) to the transcription factor vitamin D receptor (VDR), a direct effect on gene regulation. The relation of thousands of genomic VDR-binding sites to a few hundred primary 1,25(OH)(2)D(3) target genes is still largely unresolved. We studied chromatin domains containing genes for the adhesion molecules CD97 and LRRC8A, the glucose transporter SLC37A2 and the coactivator NRIP1.
