Personalized Medicine Approach Provides More Benefit for Patients with High Cholesterol than Current Guidelines

by Walter Jessen in Highlight HEALTH

A recent study in the Annals of Internal Medicine found that a simple tailored treatment for high cholesterol provides more benefit per person treated and prevented significantly more coronary artery disease morbidity and death than the currently recommended treat-to-target approaches....

Mother’s Love

by Moselio Schaechter in Small Things Considered

by Elio Binary fission is a most impressive invention. In one fell swoop, it ensures that progeny cells are born alike and endowed with the same potential for growth and survival. Simple as it sounds, it must have taken considerable evolutionary contortions to make it function so well throughout the living world. But there are cells that have adopted an...... Read more »

The Body Does Work to Break Down Damaging Aggregates

by Reason in Fight Aging!

One of the causes of age-related degeneration and disease is the buildup of amyloid clumps and other forms of aggregated metabolic byproducts. A brief outline: As we get older, many different types of errant and unwanted proteins, the chemical byproducts of metabolism, build up and accumulate between our cells. Collectively these are known as forms of amyloid, a term that might be familiar to you in connection with Alzheimer's disease, but there are many other types of amyloid beyond that implic........

Escape! Crop-Specific Gene Flow to Wild Relatives

by Cody Cobb in Biofortified

As a molecular biologist, most of my work is done on a bench at or below room temperature. I can count on one hand the number of times I’ve been to a research field because I have more than two fingers. I’ve never taken a course in ecology, and I’ve rarely dealt with full, intact [...]...

Physical Actvity and Mental Health

by PhD Blogger in Exercise Psychology

Babyak (2000) examined the use of physical activity as a treatment for depression. Participants classified as clinically depressed were given, aerobic exercise, drugs or both as treatment. The exercise only group recovered as well as the other groups but had a lower relapse rate, perhaps caused by the participants feeling that they had a more active role in their treatment. The exercise group also a side effect of the participants getting fitter! There are many other studies associating par........ Read more »

World’s Longest Lasting Tomato

by Akshat Rathi in Contemplation

Researchers in Delhi at the National Institute of Plant Genome Research have developed a tomato that has a shelf-life of 45 days. A. Datta and S. Chakraborty with co-workers report in the paper published in the Proceedings of the National Academy of Sciences that they identified the ripening-specifics enzymes and silenced those genes through RNA interference.

Lexical effects in speech perception

by Greg Hickok in Talking Brains

The influence of the motor system on speech perception has been getting tons of high profile attention lately and "sensorimotor theories" of speech perception are gaining popularity. For an interesting example of the such a theory, check out Jean-Luc Schwartz et al.'s, The Perception-for-Action-Control Theory (PACT): A perceptuo-motor theory of speech perception. It is all well-and-good to understand the contribution of motor information to speech perception, but let's not forget that there is........ Read more »

Should we entrust children to the care of the devoutly religious?

by Tom Rees in Epiphenom

The Catholic Church is in the news again - this time in Germany - as a result paedophile priests being outed after years of cover-ups. Traditionally, we have entrusted vulnerable children to the care of the devoutly religious, on the grounds that, of all people, they can be relied upon not to abuse those in their care. Does that assumption hold up? We can't extrapolate too wildly from the particular problems of the Catholic Church, but there are other data out there.So I took a look at the evide........

How close are we to a cure for HIV / AIDS?

by Dave in The Daily Monthly

When I began work on this month’s project, I contacted a clinician, a case manager, and a scientist to get their perspectives on how we’re making progress fighting HIV and AIDS. I’ve introduced you to the clinician and the case manager, but not the scientist.

A conflict between exercise and longevity control?

by ouroboros in Ouroboros: Research in the biology of aging

We know that exercise is good for us, and increasingly we’re understanding how it works at the molecular and cellular level: Physical activity boosts levels of heat shock proteins, which help cells resist stress; it also improves mitochondrial function in a manner reminiscent of calorie restriction (CR). Our knowledge is sophisticated enough that we can [...]... Read more »

Platelet rich plasma

by PalMD in White Coat Underground

Several months ago, Dr. Val Jones wrote about a growing fad in the treatment of musculoskeletal disorders. The therapy, called platelet rich plasma (PRP) injection, involves taking a small amount of blood from a patient, spinning it down in a centrifuge, and then injecting the plasma component into...somewhere. This treatment is becoming increasingly popular, and can be very lucrative for doctors. But does it work?

Blood platelets are very biologically active particles and plasma is not a bl........ Read more »

The Russian Fox Study

Low back pain: unfit? just not doing much? or something else

by Bronwyn Thompson in Healthskills: Skills for Healthy Living

For as long as I’ve been working in pain management (and probably well before), I’ve heard patients being described as ‘deconditioned’. From what we know about the effects of staying in bed because of illness or injury, it makes sense to think that if a person does very little they will become unfit. [...]... Read more »

Meat on a String: A Possible Limit to Corvid Intelligence?

by John Beetham in A DC Birding Blog

Common Raven / USFWS Photo Corvids – crows, ravens, jays, and magpies – are well known to be among the most intelligent of birds. Along with parrots, corvids have been a frequent subject of avian intelligence studies. Experiments have documented problem-solving and tool use, both in the lab and in the wild. Many of the recent experiments have tested intelligence in New Caledonian Crows (Corvus moneduloides), but tests of Ravens (Corvus corax) and Rooks (Corvus frugilegus) have also found pro........
