Elite Soccer Players Have High Rates of Osteoarthritis
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: Elite soccer athletes may be at an increased risk for knee and ankle osteoarthritis compared with the general population. This group should be identified as high risk and preventative measures should be taken.
While participation in elite-level sports is often viewed as a good thing, there is an established increased risk of short-term injuries (e.g., sprains, strains). This increased injury risk may leave athletes at an increased risk for long-term disability (e.g., oste........ Read more »

RDoC and the cross-roads of psychiatry
by Paul Whiteley in Questioning Answers
The Irish poet Brendan Behan is, I think, credited with the phrase: "There's no bad publicity except an obituary". One wonders how appropriate this phrase might be to the 'diagnostic Bible' (except that it isn't) which is DSM-V which is poised to make its entrance into the World in the coming days.The real Homer @ Wikipedia Indeed, the story of DSM-V even before it hits the diagnostic shelves of all good psychiatric bookshops, has the makings of an epic piece of poetry or literature, o........

Alligator stem cell study paves the way for tooth regeneration in humans
by beredim in Stem Cells Freak
Unlike most vertebrates which can replace lost teeth through their entire lives, humans come with only two sets, baby teeth and adult teeth, then they simply lose the ability for tooth renewal.. However, a new study on alligators by researchers at the Keck School of Medicine, University of Southern California (USC) may someday allow doctors to stimulate tooth regeneration in humans as well.Read More...

Sneaking viruses into the brain: cancer treatment
by Rebecca Nesbit in The Society of Biology blog
This week, 13th-19th May, a campaign is being launched to highlight the hidden aspects of brain injury and help with the correct diagnosis of these potentially terminal conditions. The campaign is part of Action for Brain Injury (ABI) week, organised by Headway.
Brain injury is an umbrella-term for a number of conditions, including brain trauma, stroke and brain tumours. These conditions can often go unnoticed externally, yet are extremely damaging internally. It is therefore vital that GPs c........ Read more »

Serotonin is crucial for exercise-induced neurogenesis
by beredim in Stem Cells Freak
It's a well known fact that exercise induces stem cells in the hippocampus, a important brain area, to become neurons, a process known as neurogenesis However, up until now little was known about the deeper mechanisms involved in this process. Now, a new study on mice by researchers at the Max Delbrück Centre (MDC), Berlin-Buch reveals that serotonin plays a direct role in exercise-induced neurogenesis.Read More... Read more »

How to Convince People WiFi Is Making Them Sick
by Elizabeth Preston in Inkfish
All it takes is an antenna on a headband. If you've got a breathless video report on the dangers of wireless internet connections, that will help your case. It doesn't take much, though, to turn an ominous hint into a real headache.
Some people consider themselves sensitive to electromagnetic fields. They report symptoms such as burning skin, tingling, nausea, dizziness, or chest pain, and they blame their malaise on nearby power lines, cell phones, or WiFi networks. A recent Slate arti........ Read more »

Bingeing and Purging: Keeping the “Positives” and Eliminating The Negatives?
by Liz in Science of Eating Disorders
I have been fascinated and perplexed by reports of the seemingly invigorating and anxiety reducing effects of bingeing and purging (purging by self-induced vomiting). Personally, I cringe at the idea of self-induced vomiting and have always wanted to avoid vomiting at all costs, including during food poisoning. The insight from recent blog entries and the subsequent comments has made an impact on me. I see that the motivation to engage in bingeing/purging (b/p-ing) behavior ........ Read more »

High-Tech Tools Do Not Always Create a Better Test
by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: The balance error scoring system (BESS) test is more effective in assessing high school age students’ concussions compared to the Balance Accelerometer Measure (BAM) assessment. The tandem leg stances on firm and foam surface of the BESS test are the most sensitive and specific positions for the detection of a concussion.

An interesting case report on autism and diet
by Paul Whiteley in Questioning Answers
Nodding syndrome.Ever heard of it? Well, up until a few days ago I hadn't. That is before coming across articles on the topic by Richard Idro and colleagues* (open-access) and Angelina Kakooza-Mwesige and colleagues** (open-access). Whilst not specifically my line of expertise or interest, I was intrigued to read about how nodding and other symptoms of the epileptic variety, at least in some cases, seemed to be precipitated by food and showed a potential nutritional angle.Curving spacetime&........

Cellular Alchemy: Converting Fibroblasts Into Heart Cells
by Jalees Rehman in The Next Regeneration
Medieval alchemists devoted their lives to the pursuit of the infamous Philosopher's Stone, an elusive substance that was thought to convert base metals into valuable gold. Needless to say, nobody ever discovered the Philosopher’s Stone. Well, perhaps some alchemist did get lucky but was wise enough to keep the discovery secret. Instead of publishing the discovery and receiving the Nobel Prize for Alchemy, the lucky alchemist probably just walked around in junkyards, surreptitiously c........ Read more »

Depression or antidepressant use linked to C.diff infection?

"There's no mystical energy field that controls my destiny". So said a very sceptical Han Solo.Regular readers might know that I'm a bit of fan of the whole gut-brain axis; indeed other kinds of axes too.

Wii Balance Boards for Testing Postural Control During Single-Leg Stance Tests
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: The Wii Balance Board is an acceptable substitute for measuring the center of pressure during single leg stance balance tests.
While a laboratory grade force plate is the gold standard for both testing and training balance, these force plates are limited to research laboratories. Due to the importance of balance testing and training during the rehabilitation process, a cost effective, widely available and portable force plate is desirable. Therefore, Huurnink and colleagues........ Read more »
