Calcium News and Research RSS Feed - Calcium News and Research

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.

Stem cell research opens doors to potential new treatments for bipolar disorder

Stem cell research opens doors to potential new treatments for bipolar disorder

What makes a person bipolar, prone to manic highs and deep, depressed lows? Why does bipolar disorder run so strongly in families, even though no single gene is to blame? And why is it so hard to find new treatments for a condition that affects 200 million people worldwide? [More]

Researchers create statistical model to predict whether heart scans are useful in prescribing statins

Researchers create statistical model to predict whether heart scans are useful in prescribing statins

As long as inexpensive statins, which lower cholesterol, are readily available and patients don't mind taking them, it doesn't make sense to do a heart scan to measure how much plaque has built up in a patient's coronary arteries before prescribing the pills, according to a new study by researchers at UC San Francisco.

Some "junk foods" can help child's oral health

If there's one thing that all dentists have in common, it's that they regularly see young patients with tooth decay. Roughly 41 percent of children age 2-11 have had decay in their primary teeth, while approximately 32 percent of children ages 9-11 have decay in their permanent teeth. [More]

Study links association between eating red, processed meat and risk of developing cancer in gut

​Recent reports warn about a link between eating red and processed meat and the risk of developing cancer in the gut. These reports have resulted in new nutritional recommendations that advise people to limit their intake of red and processed meats. [More]

New bioinspired gel material could help repair damaged teeth and bone

A bit of pressure from a new shrinking, sponge-like gel is all it takes to turn transplanted unspecialized cells into cells that lay down minerals and begin to form teeth. [More]
Calcium and vitamin D supplements can improve cholesterol profiles in postmenopausal women

Calcium and vitamin D supplements can improve cholesterol profiles in postmenopausal women

Calcium and vitamin D supplements after menopause can improve women's cholesterol profiles. And much of that effect is tied to raising vitamin D levels, finds a new study from the Women's Health Initiative just published online in Menopause, the journal of The North American Menopause Society.

When Elizabeth "Beth" Johnson stood up from working at her computer Oct. 28, she noticed "a kind of funny feeling" in the back of her neck. By Nov. 2, the sensation had become an excruciating headache that came on whenever she tried to stand or sit upright. [More]

Researchers examine whether vitamin D deficiency occurs during early stage of type 1 diabetes

Low levels of vitamin D are commonly found in people with type 1 diabetes. But even children who have multiple positive islet autoantibodies without manifest type 1 diabetes have lower levels of vitamin D in their blood. [More]

Scales of zebrafish suitable for identifying new drugs for treating bone diseases

The scales of the zebrafish are very suitable for identifying potential new drugs for treating bone diseases. This is good news because it means fewer mice and rats will be needed for that work. [More]
