Abstract Vitamin D deficiency and hypocalcemia are associated with gestational hypertension. Therefore, we hypothesized that umbilical cord [Ca(2+)] and [vitamin D] are correlated with perinatal blood pressures. Mothers and newborns comprised vitamin D sufficient (vitamin D ≥50 nM, range 52-111 nM, n = 14), and vitamin D deficient groups (vitamin D <50 nM, range 13-49 nM, n = 29). Cord ...

One theory within chiropractics proposes that vertebral subluxation in the upper cervical region induces spinal cord compression sufficient to alter spinal cord efferent output. We report on the feasibility of three different experimental approaches to test this theory. A high threshold electrical-evoked somatosympathetic reflex was recorded in adrenal or renal ...
