More pain means real gain for CRPS treatment

Los Angeles, London, New Delhi, Singapore and Washington DC (November 12, 2009) –The saying "more pain, more gain" may be true for those already in terrible pain due to a chronic and debilitating condition, contrary to received wisdom. For those with Type I Complex Regional Pain Syndrome (CRPS), working through the pain of an aggressive physiotherapy program often leads to far better results than a more cautious pain-free approach. That was the result of a new study in Clinical Rehabilitation, published this week by SAGE.

Shape of things to come: structure of HIV coat could lead to new drugs

PITTSBURGH, Nov. 12 – Structural biologists at the University of Pittsburgh School of Medicine have described the architecture of the complex of protein units that make up the coat surrounding the HIV genome and identified in it a "seam" of functional importance that previously went unrecognized. Those findings, reported today in Cell, could point the way to new treatments for blocking HIV infection.

Surgeon 'gluing' the breastbone together after open-heart surgery

An innovative method is being used to repair the breastbone after it is intentionally broken to provide access to the heart during open-heart surgery. The technique uses a state-of-the-art adhesive that rapidly bonds to bone and accelerates the recovery process.

Use of stem cells in regenerative medicine may have deleterious effects, research finds

The use of stem cells in regenerative medicine is not always beneficial for human health, it may even be harmful according to a work done by the University of Granada and University of León. Scientists have demonstrated that transplantation of human mononuclear cells isolated from umbilical cord blood exerted a deleterious effect in rats with liver cirrhosis.

Mechanical ventilation for patients with lung damage don't always work as planned

TORONTO, Ont., November 12, 2009 — As more Canadians are diagnosed with H1N1 influenza infection, some will be admitted to hospital. The most severely affected may be treated in the intensive care unit (ICU) and placed on a mechanical ventilator to help them breathe while they recover from the infection.

While mechanical ventilation clearly saves the lives of many people felled by serious illness, in some cases, this supportive measure has been known to damage the lungs, says Dr. Arthur S. Slutsky, a scientist at St. Michael's Hospital in Toronto.

Monogamous relationships mean healthier babies, study finds

Faculty of 1000 reviewers examine a study from New Zealand on whether prolonged exposure to the father's semen protects new mothers against pre-eclampsia and having an undersized baby

In this study by Kho and colleagues at the University of Auckland, published in the Journal of Reproductive Immunology, 2507 first-time pregnant women were interviewed about the length of their relationship with the baby's biological father.

Hoping for a fluorescent basket case

Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. Much has been learned about HIV-1, the virus that causes the disease. However, basic aspects of person-to-person transmission and of the progressive intercellular infection that depletes the immune system of its vital T cells remain imperfectly understood.

Fertility preservation need not delay breast cancer treatment for younger women

CHICAGO (November 12, 2009) – A new study published in the November issue of the Journal of the American College of Surgeons shows that breast cancer patients under 40 years old who undergo fertility preservation do not face a significant delay in the treatment of their disease when their care is coordinated in a timely fashion.

Genetic no-entry zones may help develop new treatments for AIDS

The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for developing new, specific AIDS drugs.

Narrow line between love and jealousy defined by oxytocin

A new study carried out at the University of Haifa has found that the hormone oxytocin, the "love hormone", which affects behaviors such as trust, empathy and generosity, also affects opposite behaviors, such as jealousy and gloating. "Subsequent to these findings, we assume that the hormone is an overall trigger for social sentiments: when the person's association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone increases negative sentiments," explains Simone Shamay-Tsoory who carried out the research.

Sweet as can be: how E. coli evolved to survive in the human gut

Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut.

New explanation for nature's hardiest life form--bacterial spores

Got food poisoning? The cause might be bacterial spores, en extremely hardy survival form of bacteria, a nightmare for health care and the food industry and an enigma for scientists. Spore-forming bacteria, present almost everywhere in our environment, can also cause serious infectious diseases, such as tetanus, anthrax, and botulism. Now researchers from Lund University and the U.S. have made a breakthrough in our understanding of the molecular characteristics of spores that in the long term may lead to new methods for sterilizing food and medical equipment.

Too much selenium can increase your cholesterol

A new study from the University of Warwick has discovered taking too much of the essential mineral selenium in your diet can increase your cholesterol by almost 10%.

Selenium is a trace essential mineral with anti-oxidant properties. The body naturally absorbs selenium from foods such as vegetables, meat and seafood. However, when the balance is altered and the body absorbs too much selenium, such as through taking selenium supplements, it can have adverse affects.

Bipolar disorder explained by faulty circadian clock genes

Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder.
