The swaying and postural instability frequently seen in elderly subjects had not been analyzed quantitatively in detail until the introduction of computerized posturography. In order to assess the changes of body sway with aging, we performed computerized posturography in 144 subjects (51 men and 93 women, between the ages of 22 and 88 years) without(More)
We conducted a randomized, double-blind trial to assess the effect of 28.2 μg teriparatide versus placebo (1.4 μg teriparatide) on reduction of the incidence of vertebral fractures. Individuals enrolled in this study included patients with primary osteoporosis with one to five vertebral fractures and capable of self-supported walking. Attention was focused(More)
Adenylate cyclase responses to pituitary hormones including adrenocorticotropic hormone (ACTH), biogenetic amines, pros-taglandin E, (PGE,), angiotensin II, and glucagon were evalu ated in adrenocortical tumors and hyperplastic adrenal tissues, obtained from patients with Cushing's syndrome at surgery, and in normal adrenals. The adenylate cyclase of two(More)
With the use of stable isotopes, this study aimed to compare the bioavailability of active absorbable algal calcium (AAACa), obtained from oyster shell powder heated to a high temperature, with an additional heated seaweed component (Heated Algal Ingredient, HAI), with that of calcium carbonate. In 10 postmenopausal women volunteers aged 59 to 77 years(More)
INTRODUCTION Osteoporosis and tooth loss have been linked with advancing age, but no clear relationship between these conditions has been proven. Several studies of bone mineral density measurements of the jaw and spine have shown similarities in their rate of age-related deterioration. Thus, measurements of jawbone density may predict lumbar vertebral bone(More)
To identify the possible role of calcium ions in cell differentia tion, we studied the extracellular Ca2+requirement and the effect of Ca2+/phospholipid-dependent protein kinase (protein kinase C) inhibitor on proliferation and differentiation of human promye-locytic leukemic HL-60 cells. HL-60 cells grew equally well in 0.1 and 1.0 mw Ca2+ media. The(More)
