Variations in the concentration of calcium in the haemolymph and of total body calcium in Austropotamobius pallipes have been investigated. Haemolymph calcium concentration was independent of both body size and sex. During premoult the calcium concentration of the haemolymph rose from 11-8 ITIM/1 to 15-0 HIM/I. After the moult the calcium concentration remained high during stages A and B but de...

Intraand interindividual components of variation in ionized calcium among normal individuals have been estimated. The basic data were means of duplicate analyses of total serum calcium, total serum protein, and serum albumin from 68 normal subjects, 10-12 weekly samples per person. The McLean-Hastings equation was used to estimate ICa2i. Use of observed albumin/globulin ratios, instead of an as...

conclusions: in the current study, quality of life was correlated with serum calcium level, calcium-phosphate product, and serum pth level, while hospitalization was correlated only with serum phosphorus level. however, quality of life was inversely correlated with hospitalization. background: significant impairment in health-related quality of life (hrqol) among dialysis patients could be part...

BACKGROUND High calcium intake has been associated with both high bone mineral density (BMD) and high urinary estrogen metabolites. However, the role of dietary calcium and calcium supplements on estrogen metabolism and BMD remains unknown. OBJECTIVE The objective was to investigate the importance of the source of calcium intake on estrogen metabolism and BMD. DESIGN The average total daily...

A a Abstract. Aberrations in calcium homeostasis are common observed in patients with chronic renal failure. Measure of total calcium does not reflect the real variation of the calcium status. The proper method to evaluate this issue in hemodialysis patients has not been completely defined. This study aimed to compare the corrected serum calcium levels to ionized calcium levels in hemodialysis ...

Background: Nephrolithiasis is a global health problem that is growing exponentially in the developed and developing countries. This study aimed to determine the dietary diversity score (DDS) and its association with nutrient adequacy in patients with calcium oxalate kidney stone. Methods: The present cross-sectional study was conducted on 276 male patients with calcium oxalate kidney stone. Th...
