Serum 25-Hydroxyvitamin D Is Unaffected by Multiple Freeze-Thaw Cycles

Serum 25-hydroxyvitamin D is unaffected by multiple freeze-thaw cycles.

Optimal serum 25-hydroxyvitamin D levels for multiple health outcomes.

Recent evidence suggests that higher vitamin D intakes beyond current recommendations may be associated with better health outcomes. In this chapter, evidence is summarized from different studies that evaluate threshold levels for serum 25(OH)D levels in relation to bone mineral density (BMD), lower extremity function, dental health, risk of falls, admission to nursing home, fractures, cancer p...

Serum 25-hydroxyvitamin D levels and risk of multiple sclerosis.

CONTEXT Epidemiological and experimental evidence suggests that high levels of vitamin D, a potent immunomodulator, may decrease the risk of multiple sclerosis. There are no prospective studies addressing this hypothesis. OBJECTIVE To examine whether levels of 25-hydroxyvitamin D are associated with risk of multiple sclerosis. DESIGN, SETTING, AND PARTICIPANTS Prospective, nested case-contr...

Serum 25-hydroxyvitamin D (25-OH-D) in obese adolescents.

BACKGROUND There is increasing evidence that vitamin D deficiency is common and has been associated with several non-bone related outcomes, including insulin resistance, type 2 diabetes and cardiovascular disease. The influences of gender, puberty, and adiposity on serum hydroxyvitamin D (25-OH-D) levels and the relationship between 25-OH-D and insulin resistance in obese children were studied....

serum 25-hydroxyvitamin d in patients with major depressive disorder.

we investigated the association between serum 25(oh) d levels and depressive symptoms in patients with major depressive disorder (mdd).eighty-five adults, 44 drug free patients with mdd and 41 apparently healthy controls, participated in the study. the hamilton depression rating scale was used to assess severity of major depression. mental health of the controls was assessed according to dsm-iv...
