Calcium News and Research

RSS

Calcium, the most abundant mineral in the body, is found in some foods, added to others, available as a dietary supplement, and present in some medicines (such as antacids). Calcium is required for muscle contraction, blood vessel expansion and contraction, secretion of hormones and enzymes, and transmitting impulses throughout the nervous system. The body strives to maintain constant concentrations of calcium in blood, muscle, and intercellular fluids, though less than <1% of total body calcium is needed to support these functions.

The remaining 99% of the body's calcium supply is stored in the bones and teeth where it supports their structure. Bone itself undergoes continuous remodeling, with constant resorption and deposition of calcium into new bone. The balance between bone resorption and deposition changes with age. Bone formation exceeds resorption in growing children, whereas in early and middle adulthood both processes are relatively equal. In aging adults, particularly among postmenopausal women, bone breakdown exceeds formation, resulting in bone loss that increases the risk of osteoporosis over time.

Cinacalet helps control overactive thyroids, a major complication of advanced kidney disease

A new drug can help control an overactive thyroid, a major complication of advanced kidney disease, by playing a trick on the gland, a new study finds. The drug, cinacalet, is much more effective at keeping the parathyroid gland working normally than a placebo, according to the study. It may be a good alternative to standard therapy, researchers said.

Effects of lead in petrol are well-known however a recent additive to petrol manganese may be just as toxic

The disastrous environmental and health effects of lead in petrol are well-known, and western countries have been phasing it out for many years now. However, a recent additive to petrol - manganese - may be just as toxic. A Macquarie University study aims to find out.

Fluorescent molecule used to examine real time chemical reactions that result in smooth-muscle contraction

Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks in when the first pathway is limited.

Research team has found a new way to streamline gene isolation to determine their functions

A single strand of plant or animal DNA may contain tens of thousands of genes, each programmed to produce a specific protein essential for the growth or survival of the organism. The challenge for geneticists is to isolate individual genes and determine their function -- a painstaking process often requiring years of laboratory trial and error.

First large-scale clinical trial of chelation therapy, a controversial treatment for heart disease

NYU Medical Center has begun enrolling patients in the first large-scale clinical trial of chelation therapy, a controversial treatment for heart disease widely practiced by complementary and alternative medicine physicians. The new, government-funded nationwide study will determine whether the therapy benefits people with coronary artery disease, the leading cause of death for both men and women in the United States.

Discovery of molecule that is part of the machinery that mediates the sense of hearing

A group of scientists at The Scripps Research Institute, at the University of California in San Diego, and at the Oregon Hearing Research Center and Vollum Institute at Oregon Health & Science University have discovered a key molecule that is part of the machinery that mediates the sense of hearing.

Anti-ageing formula recalled due to excessive vitamin D3

Aloe Commodities International, Inc., Carrollton, Texas, is recalling 1600 bottles of Solutions IE Ageless Formula II, Lot numbers P2207 and P2221 because they contain a significantly higher-than-labeled level of vitamin D3. (Approximately 188,640 International Units (IU) are present in each serving size of 6 capsules instead of the intended level of 400 IU). The product is distributed by Solutions International, Inc., Orem, UT.

Approval for FOSRENOL (lanthanum carbonate), which controls phosphate levels in renal dialysis patients

Sweden's MPA has today granted the first regulatory approval in the world for FOSRENOL (lanthanum carbonate), a non-calcium, non-aluminium phosphate binding medicine developed to control phosphate levels in renal dialysis patients. Sweden will now become the Reference Member State in the EU Mutual Recognition Procedure for FOSRENOL, and this is the first step in securing marketing approval throughout Europe. A submission has also been made by Shire to gain marketing approval for FOSRENOL in the United States.

Fruits and vegetables promote stronger bones in girls

Although calcium usually gets top billing when it comes to bone health, fruits and vegetables may also promote stronger bones in girls, new study findings suggest.

New Computer-Aided Approach Helps Doctors Tailor The Dosage of Abciximab

A computer-aided approach -- based on software-that-learns, promises to provide a new tool that helps doctors tailor the dosage of abciximab, a medicine frequently used before angioplasty to lessen the chance of heart attack.

New Theory About Alzheimer's Disease

A group of scientists at The Scripps Research Institute has proposed a new theory about the cause of Alzheimer's disease, the progressive neurodegenerative disorder that currently afflicts some 4.5 million Americans. According to the hypothesis, the disease arises as a consequence of inflammation, which creates abnormal metabolites out of normal brain molecules.
