Impact of Nutritional Status on Body-Contouring Surgery

by Arya M. Sharma in Dr. Sharma's Obesity Notes

One of the unwanted complications of gaining a lot of weight and then losing it, is the sometimes grotesque amounts of unwanted skin that patients are left with. This excess skin can be both aethetically distressing but also cause functional and dermatological problems.
With the advent of bariatric surgery, a parallel discipline of plastic surgery specialising [...]... Read more »

An umbrella against the mutational showers

by Razib Khan in Gene Expression

Mutations are as you know a double-edged sword. On the one hand mutations are the stuff of evolution; neutral changes on the molecular or phenotypic level are the result of from mutations, as are changes which enhance fitness and so are driven to fixation by positive selection. On the other hand mutations also tend to [...]... Read more »

“Huge leap” forward is just a small step for cancer vaccine research

by Cancer Research UK in Cancer Research UK - Science Update

This weekend, newspaper headlines announced that “Cancer Scientists hail ‘huge’ leap towards jab that targets tumours” and “’Holy Grail’ cancer vaccine that blasts tumours in weeks hailed as huge leap in fighting disease”. Not only are these headlines overhyped and misleading, but the stories themselves are slightly confusing, combining the launch of a clinical trial [...]... Read more »

Improving the communication of science in conservation

by Rob Goldstein in Conservation Maven

The incorporation of current scientific research and understanding into on the ground conservation projects not only increases the effectiveness of those conservation efforts, it also builds support for their implementation. A new case study serves as an example of the benefits that come from outreach work that includes creative methods for communicating science to diverse audiences...... Read more »

Atlatls to Bows: A Very Strange Atlatl from California

by teofilo in Gambler's House

In November of 1793 a British naval expedition commanded by Captain George Vancouver arrived at the small Spanish settlement of Santa Barbara on the coast of California.  Vancouver’s primary mission was to explore and map the poorly understood northwest coast of North America, building on the more preliminary information provided earlier by Captain James Cook.  [...]...

Prehospital use of analgesia for suspected extremity fractures

by Rogue Medic in Rogue Medic

Also posted over at Paramedicine 101 and at Research Blogging. Go check out the rest of the excellent material at both sites.This is an older study that puts the prehospital pain management problem into a bit of perspective. While prehospital pain management has improved a lot in some places, other places may still be handling pain as described in this study. This is only ten years old. Attitudes are not changed so easily. The authors looked at what is probably the least controversial type of pa........ Read more »

The neural basis of déjà vu

by NeuroKüz in NeuroKüz

Reading a book for the second time can be an enlightening experience. At the same time, aspects of this experience can be confusing. During a second visit to a work previously read I suspect that to a degree everyone plays a game that involves trying to determine which parts of the story you remember well and which parts you completely forgot. But there are also parts that lie somewhere in the middle; it is these parts that boggle our minds by leaving us uncertain of whether or not the details a........ Read more »

Mobile phones and cancer: Study says ‘no’, news reports say ‘yes’…

by Michael Slezak in Good, Bad, and Bogus


-
Ahead of a landmark study, newspapers all around the world have carried news reports warning of the terrible risk faced by mobile phone users.
The story behind the story is worth a few words. Firstly, the study seems to says opposite to what all these reports claim. Secondly, the study was under embargo until the [...]... Read more »

Act-ing Well, Living Well iii : Acceptance & Willingness

ADHD and Maturation "Catch-up"

by William Yates, M.D. in Brain Posts

Child development produces marked changes in attention, impulsivity and activity levels. Preschool children present a significant challenge for the diagnosis of ADHD because of their typical activity and attention levels. It is possible that the diagnosis of ADHD in some young children might be incorrect due to delayed maturation.Swedish researchers looked at this issue in a study of children examined in grades one and two and then re-studied in eighth grade. A child who was hyperactive/inatte........ Read more »

Scientists discover the gene responsible for head regrowth: Smed-βcatenin-1

by A. Goldstein in WiSci

Although the hydra may only be known as a Greek myth, head regrowth is actually not as fantastical as it may seem.
According Greek mythology, the hydra was a nine-headed serpent slain by Hercules. What made the feat challenging was that every time Hercules cut off one of the serpent’s heads, two new heads replaced [...]... Read more »

The circadian prison

by Michelle Dawson in The Autism Crisis

I had no idea my sleep-wake cycle was pathological until I saw a presentation a few years ago by the geneticist Thomas Bourgeron. One of his interests is clock genes in autism. In fact only by speaking with him did it dawn on me that I lack a circadian rhythm.As it turns out, autistics are considered to have circadian clocks "gone bad." Two reviews (Bourgeron, 2007; Glickman, 2010) cover the evidence with respect to autism and circadian rhythms, most of it in the direction of comprehensive atypi........ Read more »

Take Two of These… And You Still Might Have Pain

by Shaheen Lakhan in Brain Blogger

Migraines are severe, often debilitating, headaches that may be accompanied by visual symptoms, as well as nausea and vomiting. Migraines may last up to 24 hours. The exact cause of migraine is unknown, and most treatment focuses on acute pain relief once the migraine begins. For many migraine sufferers, acute pain relief is often ineffective [...]...

Coffee and Cigarettes: Good for Your Brain?

by Laura E. Mariani in Neurotypical?

A recent paper by Kien Trinh et al. in the Journal of Neuroscience suggests that coffee and tobacco have a protective effect in two fruit fly models of Parkinson's disease. Surprisingly, these effects do not depend on the obvious "active ingredients" of these substances (i.e., caffeine and nicotine), but occur through some alternative mechanism.The connection between coffee consumption and lower risk of Parkinson's disease has been known for a while.
