This study was conducted to evaluate the calcium (Ca) absorption efficacy of king oyster mushroom (Pleurotus eryngii) grown on sawdust medium supplemented with Ca-sources, including oyster shell powder, and to determine the efficacy of oyster shell powder as a calcium supplement on growth, yield, spawn run and primordial formation of P. eryngii. Optimum calcination of oyster shell powder was ac...
A series of 103 early postmenopausal women completed a questionnaire about their dietary calcium intake and were then divided into three groups: those with an intake below 550 mg/day, those with an intake between 550 and 1150 mg/day, and those with an intake above 1150 mg/day. Thereafter they were given a daily supplement of 500 mg calcium for two years and had their bone mineral content measur...
Levothyroxine (L-T) is one of the most commonly prescribed medications. It is given as either physiologic replacement therapy in patients with hypothyroidism or as interventional therapy to suppress thyroid-stimulating hormone (TSH) secretion in patients with nodular thyroid disease or thyroid cancer. Patients treated with L-T4 suppressive therapy (a state known as exogenous subclinical hyperth...
This is a case of Milk-AlKali syndrome in a patient who presented with the classical triad of hypercalcemia, metabolic alkalosis and renal impairment. The source of calcium was over-the-counter calcium-containing antacid (Tums®). Milk-alkali syndrome was first recognized secondary to treatment of peptic ulcer disease with milk and absorbable alkali. Its incidence fell after the introduction of ...
BACKGROUND Calcium is an essential mineral often taken as a daily, long-term nutritional supplement. Data suggests that once-daily dosing is important with regard to long-term compliance of both drugs and nutritional supplements. OBJECTIVE This study was undertaken to compare the bioavailability of a single serving of two calcium supplements in healthy, premenopausal women. DESIGN A two-per...
The purpose of this study is twofold: to examine macro (calcium, magnesium, and phosphorus) and trace mineral (iron) concentration in oriental supplements (OS), and to define OS prevalence in elite athletes. Participants of this study were 928 varsity athletes (male: 680, female: 248) with 23 sports types. Recent 3-month dietary supplements (DS) and OS practice was surveyed during training peri...
This study investigated the effects of a combination of calcium and magnesium carbonate intestinal phosphate binders, associated with natural reno-protectant substances (the uraemic toxin binder chitosan, vasoactive peptides and an extract of Astragalus membranaceus) (Pronefra®, Virbac, France) on blood parameters and mineral balance in cats. Ten cats, 2 to 5 years old at day 0, were given the ...
Epidemiologic evidence supports a role for vitamin D in colorectal cancer (CRC) risk. Variants in vitamin D-related genes might modify the association between vitamin D levels and CRC risk. In this analysis, we did a comprehensive evaluation of common variants in the vitamin D receptor (VDR) and the vitamin D-binding protein (GC; group-specific component) genes using a population-based case-una...
BACKGROUND Gastric bypass operation has become a very common procedure for treatment of obesity. Changes in calcium absorption can result in changes in total body calcium, parathyroid hormone (PTH), and vitamin D levels. There is little known about the longterm effects of Roux-en-Y gastric bypass on calcium metabolism and bone homeostasis. STUDY DESIGN Between January 2000 and January 2006, 5...
