Umbilical cord stem cells show promise as heart failure treatment

A heart failure treatment using umbilical cord-derived stem cells may lead to notable improvements in heart muscle function and quality of life, according to a new study.

"We are encouraged by our findings because they could pave the way to a non-invasive, promising new therapy for a group of patients who face grim odds," said study corresponding author Fernando Figueroa, M.D., professor of medicine.

In this trial, 30 patients, ages 18 to 75, with stable heart failure receiving optimal drug therapy underwent intravenous infusions with either umbilical cord-derived stem cells or placebo.

Neurologists say you need magnesium supplements

These days, there is a supplement for everything. 

In brain-care, the latest must-have is a magnesium supplement, designed to reduce your levels of cortisol, the stress hormone. 

However, a new study warns pill-poppers that it's not as simple. 

People with both high and low levels of magnesium in their blood may be at a greater risk of developing dementia, according to new research.

Scientists say that if the results are confirmed, blood tests to measure magnesium levels could be used to screen for people at risk of dementia - and also to help people understand whether or not they should take a supplement.

The study involved more than 9,500 people with an average age of 65 who didn't have dementia whose blood was tested for magnesium levels.

Alarm as 'super malaria' spreads in South East Asia

The rapid spread of "super malaria" in South East Asia is an alarming global threat, scientists are warning.

This dangerous form of the malaria parasite cannot be killed with the main anti-malaria drugs, according to BBC.

It emerged in Cambodia but has since spread through parts of Thailand, Laos and has arrived in southern Vietnam.

The team at the Oxford Tropical Medicine Research Unit in Bangkok said there was a real danger of malaria becoming untreatable.

Mechanism that underlies age-associated bone loss

A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Often this is accompanied by an increase in fat cells in the bone marrow.

Researchers have now detailed an underlying mechanism leading to that osteoporosis. When this mechanism malfunctions, progenitor cells stop creating bone-producing cells, and instead create fat cells. Knowledge of this mechanism can provide targets in the search for novel bone-loss therapeutics to treat human osteoporosis with minimal side effects according to Science Daily.

The researchers found that a protein called Cbf-beta plays a critical role in maintaining the bone-producing cells. Furthermore, examination of aged mice showed dramatically reduced levels of Cbf-beta in bone marrow cells, as compared to younger mice.

Beetroot, the superfood that boosts your muscles

If you are looking for a new post-gym snack, beetroot may be the answer.

Among all the superfood’s claimed benefits for body and brain, it has now been found to help muscles recover after intense exercise according to Daily mail.

Scientists asked 30 men aged between 18 and 28, who work out at least twice a week, to do 100 intensive jump exercises.

The intense exercise caused muscle damage in their legs.
