Demerol is Not Bad, It Treats Shivering.

by Christian Sinclair, MD in Pallimed: a Hospice & Palliative Medicine Blog

Image via WikipediaIf you have spent anytime with a palliative care team in a hospital you will know of their efforts to essentially blacklist Demerol (meperidine) from use in the hospital.  Some hospitals have removed it or restricted it from the formulary all together.  In medical culture, demerol has been a go to opioid peri-OR and mostly favored by surgeons.  The drug has been purported to be less likely to cause billiary spasm, but this seems to be impacted more by cultural i........

Friday Weird Science: Doing your Kegels to Improve your Orgasms

by Evil Monkey in Neurotopia

Many of you may have heard from your doctor that doing Kegels is a good thing. It's certainly good for keeping your pelvic floor strong, to prevent problems like uterine prolapse following birth. It's also very good for keeping your bladder good and functional later in life. So do your Kegels, ladies.

However, Sci has always heard through the grapevine that Kegels were also good for...other things.

Well, are they?

Nucleotide diversity - what two new African genomes mean

by David in The Atavism

If you wanted evidence that we live in a post-genomic age you would need to look no further than the headlines in the science section of the newspaper last week. A man dubbed Inuk who lived and died in Greenland 4 000 years ago had dry earwax and might have gone bald if he lived long enough, Tutankhamun was inbred and had a cleft palate and Desmond Tutu has had his whole genome sequenced. What about the science behind the hook? Ed Yong has the the story of Inuk (whose genes tell us about migrat........ Read more »

XMRV not detected in Dutch chronic fatigue patients

by Vincent Racaniello in virology blog

The suggestion that the retrovirus XMRV is the etiologic agent of chronic fatigue syndrome (CFS) arose from a study in which the virus was found in 68 of 101 US patients. The virus was not detected in two independent studies of 186 and 170 CFS patients in the United Kingdom. A new Dutch study has also [...]... Read more »

Prion diseases: protein is enough

by Michael Clarkson in Conformational Flux

Spongiform encephalopathies are transmissible diseases that can have a major economic impact on agricultural exports, and pose a significant challenge for surveillance of the food supply. Scientists generally believe that these diseases are transmitted via a self-propagating, aberrant conformation of the prion protein (PrP). This prion hypothesis suggests that PrP alone should be sufficient to cause symptoms or death. If this hypothesis is true, then it should be possible to reproduce the diseas........ Read more »

Echoes of the Past

by teofilo in Gambler's House

There’s a spot near the west end of the Pueblo Bonito parking lot, close to the spot where guided tours begin, where you can yell something in the direction of the canyon wall and hear a very clear echo back.  Some of the tour guides at Chaco regularly demonstrate this impressive effect when beginning their [...]...

Is the Clinical Significance Criterion Significant?

by Neuropsych15 in The MacGuffin

The draft version of DSM-V: Revenge of the Fallen has been online for a few weeks (1) and much has already been written about it (1, 2, 3, 4). Much focus has been on what is "new" and what is "gone." One feature that is shared by the majority of DSM diagnoses, the "clinical significance" criterion, might be on its way out. Typically this criterion reads "The symptoms cause clinically significant distress or impairment in social, occupational, or other........

A personal god boosts the placebo effect

by Tom Rees in Epiphenom

The placebo effect is that spooky phenomenon that can cure people simply by convincing them they're getting real medicine (whereas they in fact are just taking a sugar pill). Although it's been reported in all sorts of areas of medicine, it's particularly potent for treating things like irritable bowel syndrome, pain, and depression.In fact, a recent analysis found that most of the effect of antidepressant medicine in people with depression was in fact due to the placebo effect (but the effect........

Social Cognition in Dogs, or How did Fido get so smart?

Figure 1: Dogs are pretty intelligent.
Domesticated dogs seem to have an uncanny ability to understand human communicative gestures.

The power of prediction reduces activation in the primary visual cortex

by William Lu in The Quantum Lobe Chronicles

Prediction is an invaluable skill for navigating through complex environments. Somehow the brain generates predictions about perceptual inputs it's likely to receive using contextual information from recent memory. Statistical regularities are learned (e.g. movement and attack patterns of Mega Man bosses) and lead to less activation in corresponding brain areas. The brain is truly a miserly organ. "Why put in more work than I have to when I know what's gonna happen next", says the brain. Alink a........ Read more »

Research demonstrates that marine protected areas aid coral reefs

by Katie Kline in EcoTone

Research has shown that marine protected areas (MPAs)—areas where fishing and other potentially destructive activities are regulated—are benefitting, not just the fish habitats they are known to aid, but nearby coral reefs as well. MPAs may benefit corals by restoring reef-based food webs and protecting damage from anchors and nutrient runoff.... Read more »

It's What You Learn, Not What You Think

by Cole Bitting in Fable

Some symptoms of OCD might be describable as pathological doubt, for instance, that one’s hands are clean or that the doors are locked. A review of OCD treatments states, “pathological doubt is one of the central manifestations of this illness. The person goes to the door, shuts it, locks it, feels that it is locked, knows that it is locked, turns around, and walks away. All of a sudden, he or she feels that it is absolutely necessary to go back and check. It appears clinically that the m........ Read more »

Invasive species runs out of evolutionary "steam" as it invades

by Jeremy Yoder in Denim and Tweed

For invasive plants, flowering time is a trait that may often be under selection during colonization—when a plant flowers determines its climatic tolerances, its vulnerability to herbivores, and its compatibility with the local pollinator community. In a study just released online at Proceedings of the Royal Society B, Colautti and coauthors examined the evolution of this trait in a plant that has swept across eastern North America since its introduction from Europe: purple loosestrife, and fo........

Can biomanipulation of the sea rescue a collapsed fishery?

by Rob Goldstein in Conservation Maven

The cod stock in the Baltic Sea collapsed in the 1990s because of overfishing and climate change, and this once-valuable fishery has not yet recovered. Could intensified harvesting of sprat—a small fish that eats cod eggs and competes with young cod for planktonic food—be the solution to restore cod, as some people suggest?  ... Read more »

How Your Brain Groups Words
