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.

The association between vitamin D status and infections, hospitalization, and mortality due to COVID-19

Researchers explored the associations between vitamin D levels and SARS-CoV-2 infections, hospitalizations, and deaths in England.

Cofilin could be a potential target for mitigating atherosclerosis at early stage, finds study

A joint research team at LKS Faculty of Medicine, The University of Hong Kong (HKUMed) and Queen Mary University of London (QMUL) has discovered the molecular mechanisms of how pathological condition-mimicking mechanical stimuli lead to the early progression of atherosclerosis, a leading cause of vascular disease worldwide.

Researchers examine link between long-term use of blood pressure drugs and breast cancer risk

Curtin University researchers will examine if the long-term use of a popular blood pressure medication increased the risk of breast cancer in almost 200,000 women as part of a new project supported by the Federal Government.

Prenatal choline supplementation makes essential nutrient available for fetal development

The nutrient choline – shown to have long-term benefits for children whose mothers consume it during pregnancy – also helps the body more efficiently use an omega 3 fatty acid that is essential for fetal brain, cognition and vision development, a new study finds.

Fluorescence-based sensing could be a useful tool for monitoring lactate levels in living organisms

Lactate is generated in the body as a byproduct, during normal metabolism and exercise. While considered a useless waste product for a long time, recent studies have shown that lactate can be an indicator for cancer and various other diseases.

Women with obesity and overweight found to be more susceptible to fractures

New research being presented at the European Congress on Obesity (ECO) in Maastricht, the Netherlands (4-7 May), has found that women with obesity and overweight, particularly women with high waist circumference, are more susceptible to fractures than those with normal weight.

Researchers unravel why neuropsychiatric symptoms appear in Alzheimer's patients before memory loss

Researchers from Indiana University School of Medicine are studying why neuropsychiatric symptoms, such as apathy and irritability, appear in most Alzheimer's disease patients before the onset of memory loss.

New insights into the link between EMFs, calcium and Alzheimer’s disease

For almost a quarter of a century, researchers have been studying and publishing on the effect of calcium on Alzheimer's Disease. Research has led to the development of the calcium hypothesis of Alzheimer's disease, which argues that Alzheimer's is caused by excessive intracellular calcium.
