The purpose of the present review is to provide an update about the most common risk factors or medical conditions associated with renal stone formation, the current methods available for metabolic investigation, dietary recommendations and medical treatment. Laboratory investigation of hypercalciuria, hyperuricosuria, hyperoxaluria, cystinuria, hypocitraturia, renal tubular acidosis, urinary t...

background: revealing data on the role of vitamin d and calcium supplementation in bone health has led some to suggest that vitamin d and calcium treatment could also play a role in protecting bone against microgravity-induced mineral loss. objectives: the aim of the present study was to investigate the effects of vitamin d and calcium administration on microscopic and densitometric changes of ...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

Lumbar spine bone mineral density in a cross sectional study of healthy subjects increased by 0.012 and 0.016 g/cm2/year in boys and girls respectively between 5 and 11 years of age. These rates increased five-fold in girls and threefold in boys between the ages of 11 and 13 years as a result of the bone mineral content increasing more rapidly than the coronal area at this age. By the age of 11...

Pseudomonas chlororaphis strain L19, isolated from stone coal soil, has the ability to perform bioleaching to release vanadium ions from mineral ore. Here, we report the draft genome sequence and annotation of the vanadium-leaching bacterium Pseudomonas chlororaphis L19. These data provide information for understanding the genomic properties and mineral bioleaching mechanisms of strain L19.

background: we compared bone mineral density (bmd) in patients with relapsing-remitting multiple sclerosis (rrms) on interferon with that of patients with relapsing-remitting multiple sclerosis (rrms) who were not receiving interferon and healthy age- and sex-matched controls. methods: overall, 30 patients with rrms on interferon (treated patients), 30 patients with rrms but not receiving inter...

background: multiple sclerosis (ms) is a demyelinating disease which can cause many disabilities for the patient. recent data suggests that ms patients have higher risk for osteoporosis. this study was performed to investigate if the osteoporosis prevalence is higher in ms patients and to determine the possible factors affecting bone mineral density (bmd). methods: 51 definite relapsing-remitti...

investigations regarding the relationship between bone mineral density (bmd) and thyroid function tests even in the normal range are limited. therefore, the present study was conducted to investigate the relationship between bmd with thyroid function tests in elderly people. this study is a part of a prospective study about health status of the elderly people in amirkola city (ahap) which is on...

the objective of this study was to evaluate the effect of accell connexus(®) on the quality and rate of healing in experimental defects of rabbit calvarium compared to bio-oss®.twelve 2.5-3.5 kg weighing new zealand white rabbits were used. three defects (3×6 mm) were created in the cranium of the animals subsequently filled with accell connexus(®), bio-oss® or served as controls. the animals w...
