PAIN: Pain changes how pain works: what we know about central sensitization so far

by Paul Ingraham in SaveYourself

This is a direct jargon-to-English translation of an important scientific paper by Clifford Woolf, a distinguished pain researcher, published in Pain in Oct 2010. Everyone — and I do mean everyone — needs to know this. It’s owners manual stuff.

Pain itself often modifies the way the central nervous system works, so that a patient actually becomes more sensitive and gets more pain with less provocation. That sensitization is called “central sensitization” because it involves change........ Read more »

LOW BACK PAIN: Does low back increase as you age? Has it increased for humanity over the decades?

by Paul Ingraham in SaveYourself

Nearly everyone assumes that back pain increases with age because backs hurt as they start to “degenerate.” In fact, studies of low back pain have contradicted this over and over again. Although certain types of back pain are relatively absent in the young and become increasingly common with age, it doesn’t affect the overall trend: most back pain occurs in middle age, and then either declines or levels off in the last third of life — exactly the opposite of what you’d expect if b........

Presenteeism in the workplace, reviewed

by Rebecca Quereshi in Occ Psy Dot Com

Absenteeism, i. e. not showing up for work, has been the subject of much research to date. In contrast, presenteeism (defined as showing up for work when one is ill), has only received interest in recent years, with research suggesting that it might cause more aggregate productivity loss than absenteeism. Consequences of chronic presenteeism or absenteeism may include effects on downstream health status, job attendance dynamics, and organizational membership.... Read more »

Japanese Men Drink, Eat Fatty Food, Have Fun and Die

by Ultimo167 in Strong Silent Types

If you have ever had the pleasure of being in a boisterous Tokyo bar at night, eating and drinking amongst a din that would sear the armour off a tank,you get the feeling that this is what pure, hedonistic joy must be like. And, according to this article by Ikeda et al. (2011), Japanese men love it as well. The downer seems to be that while all that upbeat male bonding is good for lowering stress, the accompanying fat and alcohol brings on health effects of a less favourable kind.... Read more »

Was Steven Pinker right after all?

by Henkjan Honing in Music Matters

At the end of the 1990s, cognitive psychologist Steven Pinker infamously characterized music as “auditory cheesecake”: a delightful dessert but, from an evolutionary perspective, no more than a by-product of language. But Pinker was probably right when he wrote: “I suspect music is auditory cheesecake, an exquisite confection crafted to tickle the sensitive spots of...our mental faculties.” Or, to express his idea less graphically: music affects our brains at specific places, thereby sti........

Satellites and Sea Turtles: Can We Save the Last Member of the Genus Dermochelys?

by Kelly Grooms in Promega Connections

Let me start out by saying: I love sea turtles.  I can’t explain why, but they fascinate me. I have sweatshirts, bags and artwork with sea turtles on them. I even make jewelry with sea turtle themes. Ask anyone who knows me; I have a thing for sea turtles. So when I came across the [...]... Read more »

Did the ancient Egyptians know of pygmy mammoths? Well, there is that tomb painting.

by Darren Naish in Tetrapod Zoology

One of the things that came up in the many comments appended to the article on Bob's painting of extinct Maltese animals was the famous Egyptian tomb painting of the 'pygmy mammoth'. You're likely already familiar with this (now well known) case: here's the image, as it appears on the beautifully decorated tomb wall of Rekhmire, 'Governor of the Town' of Thebes, and vizier of Egypt during the reigns of Tuthmose III and Amenhotep II (c. 1479 to 1401 BCE) during the XVIII dynasty...

Does Mandatory Menu Labeling Change Behaviour?

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

One of the proposed strategies to nudge consumers to eat fewer calories is the mandatory labeling of menus. While this makes intuitive sense, the actual impact of this strategy is not clear.
This issue was now addressed by Eric Finkelstein and colleagues from Duke-National University of Singapore, in a study just published in the American Journal [...]... Read more »

Supply Chain Disruptions and Shareholder Wealth

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

In last weeks article (Hendricks and Singhal, 2005) I described the effects of supply chain glitches on supply chain performance. This week should be viewed an update to that.

Already in 2003 Hendricks and Singhal showed in an article the devastating effects supply chain glitches can have on the shareholder value. Up to that time a strong correlation between excellence in supply chain management and shareholder value has always been presumed. Many have alluded to the compelling bottom-line........ Read more »

Martin Luther King, Jr. & Eliot Spitzer: On letting people off the hook [Part II]:

Tricks of the Trade: Nursemaid elbow reduction

by Michelle Lin in Academic Life In Emergency Medicine

We've all seen it before while working in the ED. A parent brings in their child because they pulled on their arm, and now the child is not using it. Parents are thoroughly convinced that the child's arm is either broken or dislocated. We all recognize this as radial head subluxation or "nursemaid's elbow" and immediately attempt to reduce it. The provider takes the injured arm, supinates at the wrist and flexes at the elbow. Does the child scream? Does the parent scream and threaten to sue? Wha........ Read more »

The rise of genetic architecture

by Razib Khan in Gene Expression

In science, like most things, one prefers simple over complex whenever possible. You keep adding variables until the explanatory juice starts hitting diminishing marginal returns. So cystic fibrosis is due to a mutation at one gene, and the disease expresses recessively at that locus. The reality is that one mutation accounts for ~65-70% of cystic [...]... Read more »

How is autobiographical memory divided into chapters?

by BPS Research Digest in BPS Research Digest

How does the mind file life's episodes?
Autobiographical or 'episodic' memory describes our ability to recall past experiences and is distinct from semantic memory, which is our factual knowledge about the world. So far so good, but according to Youssef Ezzyat and Lila Davachi, psychology has so far largely neglected to investigate exactly how the brain organises the continuity of lived experience into a filing system of discrete episodes.

Ezzyat and Davachi have made a start. They had 23 par........ Read more »

New Thoughts on How Plasmodium Changes its Spots

by Lorax in Angry by Choice

Plasmodium falciparum is the leading cause of malaria in people, although there are Plasmodium species, spp., that infect virtually all the tetrapods (mammals, birds, reptiles, amphibians). As most people know, malaria is acquired from mosquito bites (Anopheles mosquitoes to be specific), because Plasmodium spp. have complex life cycles that require both an insect (mosquito) and a tetrapod host. Importantly, there is essentially no overlap between the Plasmodium spp. that cause fr........ Read more »

Speciation and reticulation

by zacharoo in Lawn Chair Anthropology

Hey, "all you lovers out there," which is how Marvin Berry introduced "Earth Angel" at the Enchantment Under the Sea dance back in good-olde 1955. And by "lovers" I mean "geneticists."
Poring over the recent Neandertal nuclear genome paper (Green et al. 2010) for seminars, we're struck by two contradictory ideas. On the one hand, the authors demonstrate pretty convincingly that Neandertals and the more 'anatomically modern' humans of Europe and Asia interbred. This doesn't come from genetic com........

Z-RNA–binding domain Zα as ribosomal inhibitor: fishing for ribosomes

by Vasili Hauryliuk in stringent response

Feng at al. in NSMB show that Z-RNA (or DNA) binding domain Zα inhibits ribosomal function. Binds to the ribosome and inhibits it! Basically does what ribosome-binding antibiotics do - they bind, freeze the ribosome in some particular conformation and thus inhibit it. Viomycin can be a gerat example of that.Better still, Zα seems to bind ribosomes nondiscriminantly (both bacterial and mammalian), so using a column with immobilized Zα you could purify ribosomes from whatever cel........
