background and objective: due to a high prevalence of osteoporosis and its costs and regarding different ways of treatment for this disease and lack of knowledge about their efficacy in fracture rate in iran, this study was designed in zanjan to determine fracture rate in hypogonadal osteoporotic women who were on different types of anti-osteoporotic treatments. materials and methods: in this h...
INTRODUCTION The choice of ideal treatment for a given lithiasis is a crucial factor for its success, minimizing the number of interventions and complications. Previous determination of stone composition and its fragility is desirable, to predict its behavior during extracorporeal shock wave lithotripsy and for evaluation of its appropriateness, or to set the indication for other techniques. ...
The purpose of this study was to assess the interactive effects of habitual physical activity (total and vigorous intensity) and calcium intake on bone mineral content (BMC) in prepubertal boys and girls. Seventy-six children, aged 8-11 yr, wore accelerometers for up to 7 days to assess activity. Calcium intake was estimated by a 4-day weighted food diary. BMC and areal density (bone mineral de...
BACKGROUND Several studies have focused on the effects of calcium intake on serum lipid concentrations in postmenopausal women. However, many premenopausal women are taking calcium supplements in China. To our knowledge, no studies have assessed whether the effects of calcium supplementation on blood lipids are similar between premenopausal and postmenopausal women. OBJECTIVE We assessed the ...
The beta subunits of voltage-dependent calcium channels are known to modify calcium channel currents through pore-forming alpha1 subunits. Of the four beta subunits reported to date, the beta3 subunit is highly expressed in smooth muscle cells and is thought to consist of L-type calcium channels. To determine the role of the beta3 subunit in the voltage-dependent calcium channels of the cardiov...
Ionically crosslinked alginate hydrogels are attractive scaffolds because of their biocompatibility and mild gelation reaction that allows for gentle cell incorporation. However, the instability of ionically crosslinked hydrogels in an aqueous environment is a challenge that limits their application. This report presents a novel method to control the dimensions and mechanical properties of ioni...
PURPOSE OF REVIEW Both dietary calcium and vitamin D are undoubtedly beneficial to skeletal health. In contrast, despite intense investigation, the impact of dietary protein on calcium metabolism and bone balance remains controversial. A widely held view is that high intakes of animal protein result in increased bone resorption, reduced bone mineral density, and increased fractures because of i...
Inadequate calcium intake can lead to decreased bone mineral density, which can increase the risk of bone fractures. Supplemental calcium promotes bone mineral density and strength and can prevent osteoporosis. Recent scientific evidence, however, suggests that elevated consumption of calcium supplements may raise the risk for heart disease and can be connected with accelerated deposit of calci...
Background: The aim of this study was to assess the association of serum adiponectin and a set of traditional cardiovascular risk factors with carotid artery intimal-medial thickness (CIMT) and coronary artery calcium score (CACS), as markers of subclinical atherosclerosis in subjects with early type 2 diabetes mellitus. Methods: Carotid artery intima- media thickness (measured by B-mode ultrso...
