Marit Bjørgen was a world-class athlete at the top of her career -- and then she decided to have a baby. How did that change her ability to train -- and her performance afterwards?
In a landmark study published this week in the BMJ, Finnish researchers show that one of the most common surgical procedures in the Western world is probably unnecessary. Keyhole surgeries of the shoulder are useless for patients with 'shoulder impingement', the most common diagnosis in patients with shoulder pain.
Scientists from the New York Stem Cell Foundation (NYSCF) Research Institute have developed a new bone engineering technique called Segmental Additive Tissue Engineering (SATE). The technique, described in a paper published online today in Scientific Reports, allows researchers to combine segments of bone engineered from stem cells to create large scale, personalized grafts that will enhance treatment for those suffering from bone disease or injury through regenerative medicine.
In a new study published in the journal Peer J this week, researchers at UniSA's Body in Mind Research Group have found people suffering osteoarthritis in the knees reported reduced pain when exposed to visual illusions that altered the size of their knees.
The Pediatric NEXUS Head Computed Tomography (CT) Decision Instrument (DI) reliably identifies blunt trauma patients who require head CT imaging and could significantly reduce the use of CT imaging.
Androgen deprivation therapy for the treatment of prostate cancer can lead to loss of muscle and bone mass. In a recent Scandinavian Journal of Medicine & Science in Sport study of elderly patients undergoing the treatment, playing football -- or what's known as soccer in the United States -- over a 5-year period was linked with preserved bone mineral density (BMD) in the neck of the leg's femur.
Supplementing a single protein found in the spinal cord could help prevent symptoms of Lou Gehrig's disease, according to a new study out of Case Western Reserve University School of Medicine. Researchers found high levels of the protein -- called mitofusion 2 or Mfn2 -- prevented nerve degeneration, muscle atrophy, and paralysis in a mouse model of the disease. Since Mfn2 is often depleted during Lou Gehrig's, the new study suggests supplementing it could be a novel therapeutic approach for the disease.
The muscles of people in intensive care are less able to use fats for energy, contributing to extensive loss of muscle mass, finds a new study co-led by UCL, King's College London and Guy's and St. Thomas' NHS Foundation Trust.
UCLA researchers have found that the PGC-1α gene, previously known to control human metabolism, also controls the equilibrium of bone and fat in bone marrow and also how an adult stem cell expresses its final cell type. The findings could lead to a better understanding of the disruption of bone-to-fat ratio in bone marrow and its health consequences, and point to the gene as a therapeutic target in the treatment of osteoporosis and skeletal aging.
HIV-positive children in South Africa are more likely to have developmental disabilities compared to children who are HIV negative. HIV-positive children ages 4 to 6 had nearly four times the odds of delays in sitting, standing, walking, and speaking, and more than twice the odds of a hearing disability and cognitive delay compared to HIV-negative children.
