Playing football or running for at least three hours a week could help teenagers counteract the potential damage to their bone health caused by prolonged spells of sitting.

An international team, including an expert from the University of Exeter, has found evidence that adolescents who spend long periods engaged in certain sedentary activities are more likely to have low bone mineral content in parts of the body where it can be an indicator of the risk of developing osteoporosis.

The team found that studying put girls at particular risk, while for boys leisure internet use posed the greatest threat. Scientists found that participating in at least three hours of certain sports could significantly reduce the threat in girls. The study found evidence of the benefits of high-intensity sports where the participant is on their feet, such as football, basketball, netball or running. (more…)

New Noninvasive Tool Helps Target Parkinson’s Disease

EAST LANSING, Mich. — Health professionals may soon have a new method of diagnosing Parkinson’s disease, one that is noninvasive and inexpensive, and, in early testing, has proved to be effective more than 90 percent of the time.

In addition, this new method has the potential to track the progression of Parkinson’s, as well as measure the effectiveness of treatments for the disorder, said Rahul Shrivastav, professor and chairperson of Michigan State University’s Department of Communicative Sciences and Disorders and a member of the team developing the new method.

It involves monitoring a patient’s speech patterns – specifically, movement patterns of the tongue and jaw. (more…)

Scientists have discovered a rare genetic mutation that increases the risk of Alzheimer’s disease.

The international team, led by researchers at the UCL Institute of Neurology, studied data from more than 25,000 people and found a link between a rare variant of the TREM2 gene – which is known to play a role in the immune system – and a higher risk of Alzheimer’s. (more…)

Molecular ‘tweezers’ break up toxic aggregations of proteins in mouse model

Last March, researchers at UCLA reported the development of a molecular compound called CLR01 that prevented toxic proteins associated with Parkinson’s disease from binding together and killing the brain’s neurons.

Building on those findings, they have now turned their attention to Alzheimer’s disease, which is thought to be caused by a similar toxic aggregation or clumping, but with different proteins, especially amyloid-beta and tau. (more…)

UCLA infectious diseases doctor played key role in finance strategy for therapy

A new international program, conceived in part by a UCLA physician, has rapidly transformed access to lifesaving anti-malarial drugs by providing cheap, subsidized artemisinin-based combination therapies in seven African countries that account for a quarter of the world’s malaria cases.

The first independent evaluation of the Affordable Medicines Facility–malaria (AMFm) program was recently published in the journal The Lancet. The program is based at the Global Fund in Geneva, an international financing institution dedicated to disbursing funds to prevent and treat infectious diseases. The evaluation shows that the program improved access to key artemisinin combination therapies, or ACTs, which offer broader protection and less antibiotic resistance than anti-malaria medications currently available in those African nations.

A Tale of Turkey Tail: The Part of the Bird Best Left Uneaten

ANN ARBOR — While most Americans look forward to eating turkey on Thanksgiving, Pacific Islanders in the U.S. and on the islands are most likely to eat a part of the bird few other Americans are familiar with: its tail.

“Turkey tail is marketed selectively to Pacific Island communities throughout the U.S. and in Pacific Island territories, as well as independent nations,” said University of Michigan researcher Sela Panapasa. “Actually it’s not the tail but a gland that attaches the tail to the turkey’s body. It’s filled with oil that the turkey uses to preen its feathers.” (more…)

Sperm Length Variation is not a Good Sign

A new study published online in the journal Human Reproduction finds that the greater the inconsistency in the length of sperm, particularly in the tail (flagellum), the lower the concentration of sperm that can swim well. The finding offers fertility clinicians a potential new marker for fertility trouble that might trace back to how a patient’s sperm are being made.

PROVIDENCE, R.I. [Brown University] — Perhaps variety is the very spice of life, but as a matter of producing human life, it could be the bane of existence. That’s the indication of a new study in the journal Human Reproduction that found men with wider variation in sperm length, particularly in the flagellum, had lower concentrations of sperm that could swim well. Those with more consistently made sperm seemed to have more capable ones. (more…)
