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.

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.

Electroacupuncture relieves neuropathic pain and anxiety by activating specific brain circuit

Neuropathic pain affects nearly 10% of the global population, and up to 60% of those individuals also struggle with anxiety or other mood disorders.

Advanced chip-based sensor identifies traumatic brain injury markers

Researchers have developed a chip-based metasurface biosensor that can detect traumatic brain injury (TBI) biomarkers at extremely low levels.

Elite athletes with higher vitamin D show healthier lipid profiles

Higher serum 25-hydroxyvitamin D levels were independently associated with lower LDL-C, triglycerides, and lipoprotein(a) in 773 male professional athletes. The cross-sectional study cannot establish causality, but it suggests that vitamin D status may be linked to cardiovascular risk-related lipid markers, even in elite athletic populations.

New miniature microscope stably images brain cells during movement

Researchers at Peking University have developed DUET, a breakthrough dual-color miniature two-photon microscope that overcomes two persistent barriers in neuroscience imaging: motion-induced signal instability and fluorescence channel crosstalk.

Study discovers epigenetic mechanism protecting tooth progenitor cells from stress

An epigenetic "mechanostat" has been discovered that protects tooth-forming progenitor cells from mechanical stress and supports lifelong tissue renewal.

Lysosomal protein stabilizes mitochondria to prevent severe heart failure

A new study published in Engineering has uncovered a regulatory mechanism linking lysosomal function to mitochondrial stability in pathological cardiac hypertrophy, identifying transient receptor potential mucolipin 1 (TRPML1) as a key protective factor against the progression to heart failure.

New gel coating delivers anti-inflammatory antibodies directly to the esophagus

There are few treatment options available for people with disorders of the esophagus. Delivering drugs directly to this part of the body is difficult, so patients are usually treated with systemic drugs, which can have unwanted side effects.

Trial finds prunes do not outperform calcium and vitamin D for male bone density

A one-year randomized trial found that daily prune supplementation did not improve total or lumbar spine bone mineral density in older men susceptible to, or with, osteopenia. Although some bone turnover biomarkers differed between prune and control groups, these changes did not translate into measurable bone density benefits beyond calcium and vitamin D3 supplementation.

Brain histamine neurons control moment-to-moment memory accessibility

The same memory can feel vivid and accessible one moment, yet stubbornly out of reach the next - even when the memory itself remains intact.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.

Realistic cellular conditions revive previously dismissed drug candidates

A drug once dismissed as ineffective suddenly worked - when scientists tested it under more realistic conditions that mimic the human body.

Moderate air pollution associated with advanced coronary artery disease

In one of the largest studies to date, researchers examined the relationship between long-term air pollution exposure and coronary atherosclerosis and found that even at moderate levels, long-term exposure to air pollution is associated with more advanced coronary artery disease.

Improved non-invasive brain stimulation targets deep-seated neurological disorders

Brain stimulation techniques can correct abnormal activity in the neural circuits involved in conditions such as Parkinson's disease and depression. However, current transcranial stimulation methods delivered through the scalp reach only the brain's surface, limiting their effectiveness.

Bee-derived propolis shows potent antiviral activity against varicella-zoster virus

Announcing a new article publication for Zoonoses journal. Varicella-zoster virus (VZV) is a clinically important human neurotropic herpesvirus that causes varicella (chickenpox) as primary infection, typically in children.

Common hypertension drugs tied to worse kidney outcomes in T2D patients

New research presented at the 63rd ERA Congress suggests that a widely used class of blood pressure medications may be associated with poorer kidney outcomes in people with type 2 diabetes (T2D), even among patients already receiving modern kidney-protective treatments.
