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.

FDA grants Mylan tentative approval for Atorvastatin Calcium ANDA

Mylan Inc. today announced that its subsidiary Mylan Laboratories Limited has received tentative approval from the U.S. Food and Drug Administration for its Abbreviated New Drug Application (ANDA) for Atorvastatin Calcium Tablets, 10 mg, 20 mg, 40 mg and 80 mg.

Heart burn drugs and hip fractures in postmenopausal women smokers: Study establishes link

A new study shows that postmenopausal women with a history of smoking who take heartburn drugs called proton pump inhibitors (PPIs) for two years or longer may be more likely to sustain a hip fracture. The risk rises with longer use say researchers. But the risk does disappear after women stop taking these drugs for two years. Further women who never smoked were not at increased risk for hip fracture even if they took PPIs regularly, the study showed. The new findings appear in the journal BMJ.

Researchers identify mechanism that leads to ischemia-reperfusion damage

For patients with incurable pulmonary conditions, a lung transplantation is the only available treatment option. However, suitable donor organs are scarce, and even getting them to prospective recipients is not easy. As Professor Alexander Dietrich of the Walther Straub Institute of Pharmacology and Toxicology at LMU explains, "An isolated lung which is no longer perfused with blood can become so severely damaged that it is no longer functional. This so-called ischemia-reperfusion injury is one of the major problems in the field of lung transplantation."

Pannexin1 protein may play an important role in mechanics of tumors

By studying tumor cell behavior in a novel "scaffold-free" 3-D system, researchers have determined that the protein Pannexin1 may play an important biomechanical role in binding tissues together, an effect that is lost in cancerous cells.

Researchers identify dual role of key player in human immune system

Northwestern University Feinberg School of Medicine researchers have identified a new and unusual role for a key player in the human immune system. A protein initially believed to regulate one routine function within the cell has proven vital for another critical step in the activation of the immune system.

AICAR might protect against heat stress in MH-susceptible individuals

Malignant hyperthermia (MH) is a life-threatening genetic muscle disorder, most commonly triggered in those at risk by certain types of drugs used during anesthesia. Heat stroke, on the other hand, most commonly occurs in individuals in response to physical exertion in hot/humid environments. While their common triggers may differ, the signs associated with MH and heat stroke are remarkably similar - uncontrolled muscle contractions, dangerous increases in body temperature, and muscle breakdown leading to the release of toxins in the blood which may cause cardiac arrhythmias and death. Immediate treatment for these conditions is crucial.

Consuming adequate quantities of dietary fiber can improve health

We should all be eating more dietary fiber to improve our health - that's the message from a health review by scientists in India. The team has looked at research conducted into dietary fiber during the last few decades across the globe and now suggests that to avoid initial problems, such as intestinal gas and loose stool, it is best to increase intake gradually and to spread high-fiber foods out throughout the day, at meals and snacks.

Experts recommend vitamin D supplementation for menopausal women

A group of experts has prepared a report on vitamin D supplementation for menopausal women after it was revealed that Europeans have suffered an alarming decrease in their levels of this vitamin. In their opinion, the ideal would be to maintain blood levels above 30 ng/ml. Vitamin D is essential to the immune system and processes such as calcium absorption.

AICAR therapy may combat heat stroke

We've all seen the story in the news before. Whether it's the death of a physically fit high school athlete at football training camp in August, or of an elderly woman gardening in the middle of the day in July, heat stroke is a serious, life-threatening condition for which there is no treatment beyond submersion in ice water or the application of ice packs to cool the body to a normal temperature.
