New findings suggest how stress may trigger gray hair

The team first hypothesized that stress causes an immune attack on pigment-producing cells. However, when mice lacking immune cells still showed hair graying, researchers turned to the hormone cortisol. Once again, they found a dead end. Infographic depicting how stem cells are depleted in response to stress, causing hair to turn gray in mice.

A cardiac calcium score is simply a number that represents how much calcium (and thus cholesterol deposit) has accumulated in the coronary arteries (the blood vessels that supply the heart). ... After the questions, we proceed to the imaging machine table (a CT scanner). This is the part that takes only a few seconds. Once patients are on the ...

Calcium intake and risk of fracture: systematic review | The BMJ

Introduction. Older men and women are recommended to take at least 1000-1200 mg/day of calcium for bone health and prevention of fractures.1 The average intake in the diet in Western countries is 700-900 mg/day, and lower in Asia and Africa, meaning that most older people would need to take calcium supplements to meet these recommendations. These guidelines for calcium intake have been widely ...

Graying hair 'could be used as a predictor for coronary artery disease'. The study found that patients with coronary heart disease had a greater hair whitening score and increased levels of ...

The Auckland calcium study: 5-year post-trial follow-up

Calcium supplements are advocated for the treatment and prevention of osteoporotic fractures. However, studies of their effects on bone mineral density (BMD) and fracture incidence have shown only small benefits [1, 2].In the Auckland calcium study, a 5 year randomised, placebo-controlled trial of calcium supplements, we observed no effect of calcium on total, forearm or vertebral fracture ...

Intravascular Ultrasound Validation of Contemporary Angiographic Scores ...

Purpose: To validate 3 angiographic scoring systems for peripheral artery calcification using intravascular ultrasound (IVUS) as the gold standard. Methods: The study employed preprocedure angiography and IVUS data from 47 patients (median age 72 years; 34 men) in the 55-patient JetStream G3 Calcium Study ( ClinicalTrials.gov identifier NCT01273623) to validate the 3 angiographic scoring ...

CorCal Study - Intermountain Healthcare

This study is evaluating the effectiveness of combining normal cholesterol testing with a CT scan of your heart. A CT is a machine that takes an image of any calcium build up that may be in the arteries of your heart. Calcium build up means that plaque is present which can lead to a heart attack or stroke.
