osteoporosis/proline

Bone is accrued and maintained primarily through the coupled actions of bone-forming osteoblasts and bone-resorbing osteoclasts. Cumulative in vitro studies indicated that proline-rich tyrosine kinase 2 (PYK2) is a positive mediator of osteoclast function and activity. However, our investigation of

In a 2-year study, we examined bone mass and calcium metabolism in 36 elderly women with moderate osteoporosis. The study period comprised 1 year of observation, during which the women received no treatment affecting calcium metabolism, and 1 year of treatment, during which all participants received

Context: Despite considerable progress in elucidating the molecular basis of various progeroid syndromes, some rare patients remain unexplained. Objective: To elucidate

With advancing age both sexes have an increased incidence of osteoporotic fractures, although fractures are more common in women than in men. Whereas in women several potential risk factors have been identified, less is known about osteoporosis in men. A total of 27 Austrian men (mean age: 65 +/- 2

Lithium carbonate is a widely used drug for affective disorders. It may effect calcium metabolism and alter parathyroid physiology by causing hypersecretion of parathyroid hormone. Patients treated with this medication might therefore be predisposed to osteoporosis. The purpose of this study was to

The activity of dipeptidyl peptidase IV (EC 3.4.14.5) in human sera from normal controls and osteoporotic patients was assayed with Gly-Pro-4-methylcoumaryl-7-amide (Gly-Pro-MCA) as substrate, at pH 8.7. The mean normal value for the activity in serum of 120 healthy subjects (ages 20-86 y) was 54.0

Rapid detection of the exact changes in bone remodelling is exceptionally important. In this paper, the latest bone remodelling biochemical markers are reviewed. Some of them have already been used for a long time, and their utility has been widely demonstrated. The newest ones, in experimental

<p>This study examined the ameliorative effect of D-3-O-methyl-chiroinositol, isolated from the stem bark of Piliostigma thonningii, on cadmium chloride-induced osteoporosis in male Wistar rats.p><p>Thirty-six rats were assigned to three

Experimental osteoporosis was induced in the rat by a combination of ovariectomy and immobilization by hemicordotomy. (Asu1,7)-eel calcitonin (CT) was administered at doses of 0.1, 0.5, 1.0, 2.5, and 5.0 MRC unit/kg, and its preventive effect on bone loss was examined. Significant bone loss was

There are few published data on the relationship between loss of bone mass due to osteoporosis and poor tooth quality. This study analyzed the effects of osteoporosis on incisor teeth and femoral bones using optical techniques in rats. Twenty female Wistar rats aged 6 months (n = 20) were randomized

Among solute carrier proteins, the organic anion transporters (OATs) play an important role for the elimination or reabsorption of endogenous and exogenous negatively charged anionic compounds. Among OATs, SLC22A9 (hOAT7) transports estrone sulfate with high affinity. The net decrease of estrogen,

Transforming growth factor beta (TGF-beta) is an important regulator of bone metabolism, its effects being intertwined with those of estrogen and vitamin D. A T-->C polymorphism in exon 1 of the TGF-beta1 gene, which results in the substitution of proline for leucine, is associated with bone mineral

Serum proline iminopeptidase and (where possible) urinary hydroxyproline were determined in 214 subjects: normal subjects, subjects with chronic kidney disease, subjects with chronic liver disease, subjects with osteitis deformans, subjects with rheumatoid arthritis, and subjects with osteoporosis.
