$Why do black South Africans have a low hip fracture rate despite low calcium intake?$

Why do black South Africans have a low hip fracture rate despite low calcium intake?

After Nelson Mandela was released from prison February 11, 1990, all children born in the great Johannesburg area were enrolled in a 20-year longitudinal study. Officially known as “Birth to Twenty,” the study and its 3,273 youth, are colloquially referred to as “Mandela’s Children.” It’s the largest and longest running study of child and adolescent health and development in Africa, and one of the few large-scale longitudinal studies in the world.

Being a couch potatoe may run in family

So, you don’t like to exercise? Maybe you could blame it on your great-great-grandparents. Similarly, if you’re a practiced and proud couch potato who suddenly woke up to the fact that you’re a “natural” athlete, the credit could also belong to your genes.

Estrogen, SERMS reduce asthma impact by halting constriction

For years, anecdotal evidence suggested that ovulating or pregnant women or post-menopausal women taking estrogen supplements, experienced fewer asthma attacks and less severe asthma symptoms, strongly suggesting that perhaps estrogen affects airway smooth muscle function by preventing the hyperresponsiveness characteristic of asthma and other chronic lung diseases.

Airway inflammation boosts infarction damage

Epidemiological studies show that the incidence of cardiovascular disease (CVD) complications are increased in long standing cases of asthma. Historically, the complications are often attributed to the chronic drug therapy used to treat asthma.

Pediatric burn victims’ recovery, diabetes aided by Fenofibrate

One of the immediate serious results of sudden extreme trauma or stress, including burns and even surgery, is insulin resistance, or diabetes. As a result, healing is delayed, especially in the case of severe burns, and since the body is unable to fully use blood sugar for energy, muscle tissue is broken down as the body scavenges for other possible energy sources.

Adding growth factor to baby formula could reduce necrotizing enterocolitis

Could it be that the most widespread and devastating gastrointestinal disease affecting premature babies could be conquered simply by adding a common polypeptide, epidermal growth factor (EGF), to infant formula? And if so, exactly how does it work, and why?

SERPINE2 identified as novel candidate gene for COPD susceptibility

Using a combination of genetic linkage, microarray gene expression and genetic association studies, a group of Brigham and Women’s Hospital/ Harvard Medical School researchers have identified a serine protease inhibitor clade E, member 2, or SERPINE2, “as a novel candidate susceptibility gene for COPD,” according to Sorachai Srisuma

Moderate aerobic exercise improves cardiovascular and nervous system function in HIV+ subjects

Researchers from Teachers College, Columbia University, and Coler Goldwater Specialty Hospital and Nursing Facility report that moderate aerobic exercise for 10 weeks, three times a week for 45 minutes each session significantly improved function of the nervous system and circulation in those with HIV disease.

Study of Anoxia could yield better anesthetics, stroke/heart attack recovery

For a human, mere minutes without oxygen (called anoxia) resulting from cardiac arrest, cerebral stroke or being trapped under water can lead to profound tissue damage and even death. However a Western painted turtle can survive anoxia for months without apparent tissue damage. Why, and how?

Could NAADP/cholecystokinin-combo attack fat from inside and out?

One traditional approach to pharmaceutical design uses so-called “first messengers” – hormones, other natural facilitators or synthetic products – to initiate various cellular cascades for the desired physiological effect. To date, despite concerted efforts at all levels of research, this approach has failed to develop a truly successful obesity drug to address this major global health problem.

Statins, other cholesterol-depleting agents, may disrupt hypertension from developing

Cholesterol-lowering agents, such as the widely-prescribed statin drugs, and cholesterol-blocking agents may prove to be “novel therapeutic agents to modify cellular calcium that contributes to the development of pulmonary hypertension,” according Hemal H. Patel who lead a multidisciplinary team of researchers at the University of California, San Diego (UCSD).

Cranberry juice may help protect against heart disease

Protection against a wide variety of diseases is among the many benefits of a diet high in whole fruits and vegetables. Cranberries over the years have been identified with preventing or ameliorating urinary tract infections and playing a positive role gum disease, ulcers and even cancer.

Children with autism have a severely abnormal metabolic profile

Chronic biochemical imbalance is often a primary factor in the development of many complex diseases but a possible metabolic basis for autism has not been well explored. Now Arkansas Children's Hospital Research Institute researchers report for the first time that children with autism have a severely abnormal metabolic profile indicating increased vulnerability to oxidative stress.

Asthma patients' immune systems respond differently with allergies

Researchers from the University of Chihuahua in Mexico report that immune systems of patients with asthma responded differently to a common laboratory challenge, depending on whether their white blood cells had been obtained during a time when they were suffering from common season allergic rhinitis or when they were free of such allergic symptoms.

Garlic protects against severe chronic pulmonary hypertension

Small daily doses of allicin, the active metabolic in garlic, proved effective in preventing a severe form of pulmonary hypertension in rats

Sea floor may yield disease cures

On Monday, the Harbor Branch drug discovery group will begin a 2-week expedition to explore the Straits of Florida in search of organisms that produce chemicals with the potential to cure diseases such as cancer and Alzheimer's.

Novel protein marker for early diagnosis of kidney failure

Researchers have found a novel protein marker that can give a rapid and early diagnosis of kidney failure in children undergoing heart surgery, reporting their results in this week’s issue of The Lancet.

Public morally obliged to take part in scientific research

John Harris, Professor of Bioethics at the Institute of Medicine, Law and Bioethics at the University of Manchester, and a leading ethicist, in an article in the Journal of Medical Ethics says the public has a moral obligation to support and take part in scientific research.

Late developers more at risk from sexually transmitted disease

Researchers at the Academic Unit of Obstetrics and Gynaecology, St Mary's Hospital, Manchester, UK, have found that late developers may run a higher risk of infection than sexually mature younger teens.

Winning triggers violence in sport

Research reported in Injury Prevention on rugby in the Welsh capital city Cardiff, have found that it is winning, not losing, that triggers violence at sports events. Their findings are based on the numbers of people requiring emergency medical treatment for assault at the time of international rugby and football matches in one capital city.
