Review on fetal pain creates controversy

A review of medical evidence, which has apparently found that fetuses don't feel pain until the final months of pregnancy, has created controversy and has presented a powerful challenge to abortion opponents.

First human gene mutation that causes extreme farsightedness

Working with an Amish-Mennonite family tree, Johns Hopkins researchers at the Wilmer Eye Institute have discovered what appears to be the first human gene mutation that causes extreme farsightedness.

Hundreds of identified genes involved in the pathophysiology of ulcerative colitis and Crohn disease

In a paper published in PLoS Medicine researchers from the German Genome Research Network have analysed the expression of thousands of genes from patients with inflammatory bowel disease (ulcerative colitis and Crohn disease) using a genome wide approach to produce a comprehensive picture of which genes are activated in these conditions.

Mouse model of Rett Syndrome displays reduced cortical activity

Sacha Nelson of Brandeis University in Waltham, MA and Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA and their colleagues report online in the Proceedings of the National Academy of Sciences Early Edition that spontaneous neuronal activity is reduced in the cortex of a knockout mouse model for the childhood neurodevelopmental disorder, Rett Syndrome.

A preoperative testing strategy may help determine stage of lung cancer more accurately

A preoperative testing strategy combining two procedures may help improve the accuracy of determining the stage of lung cancer, according to an article in the August 24/31 issue of JAMA: The Journal of the American Medical Association.

Use of general anesthesia for heroin detoxification offers no benefit when compared to two other methods

The use of general anesthesia for heroin detoxification offers no benefit when compared to two other methods, and is associated with several potentially life-threatening adverse events, according to an article in the August 24/31 issue of JAMA: The Journal of the American Medical Association.

Benefits of MAO-B inhibitors are small but may be worthwhile in some patients with early Parkinson's disease

A class of drugs known as MAO-B inhibitors may be effective in improving motor symptoms in people with early Parkinson's disease and may delay the need for treatment with other drugs, according to a new systematic review of current evidence.

Coronavirus HCoV-NL63 associated with croup

A forthcoming paper in the international, open-access journal PLoS Medicine makes the strongest association yet between a newly identified virus and the pediatric respiratory disease commonly known as croup.

Sentinel node biopsy, when performed before chemotherapy to shrink the tumor, is very reliable

New breast cancer research shows for the first time that even women with large breast tumors can benefit from a less invasive biopsy method that has been reserved until now for women with small breast cancers.

Wild ducks may be key to development of flu vaccine

According to Dutch and Swedish researchers wild ducks carry more than a half-dozen different types of avian flu virus.

Newly discovered virus linked to childhood respiratory infections

A team of Swedish researchers say they have identified a previously unknown virus that may cause many cases of serious respiratory infections in children.

MRI helps map smallest deformations inside hearts

Using magnetic resonance imaging technology, or MRI, to tag the work of millions of individual strands of heart muscle fibers, researchers at Johns Hopkins have successfully mapped the smallest deformations inside the beating hearts of 441 middle-aged and elderly men and women who have either silently developed heart disease or remained healthy.

Novel mechanism, called recursive splicing reveals how cells process large genes

Important messages require accurate transmission. Big genes are especially challenging because they combine many coding segments (exons) that lie between long stretches of non-coding elements (introns).

New technique for creating human embryonic stem cells

Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells. The fusion causes the adult cells to undergo genetic reprogramming, which results in cells that have the developmental characteristics of human embryonic stem cells.

Gene therapy advance shows potential for developing improved treatment for hemophilia

A virus that typically infects insects could help with the development of gene therapy treatment for Hemophilia A, a condition in which even a bump on the knee can cause serious internal bleeding in people.

Protein thought to promote lymphoma by merely preventing cancer cells from dying appears to actively promote cancer cell growth

A protein previously thought to merely hinder the activity of a key cellular protein linked to cancer cell death, now appears to mimic the cellular signaling of that protein; potentially leading to the development of lymphoma.

Discovery of a potential oncogene in ovarian cancer

Researchers at The University of Texas M. D. Anderson Cancer Center report they have discovered a potential oncogene in ovarian cancer, which is the leading cause of gynecological cancer death in U.S. women.

Malfunctioning bone marrow cells cause neuropathy in many people with diabetes

Malfunctioning bone marrow cells that produce insulin appear to cause a dangerous nerve condition called neuropathy that disables many people with diabetes, said a research team led by Baylor College of Medicine (BCM) in Houston.

Scientists step closer to understanding the genetic pathway involved in the development of hearing

New research findings, published online in the journal Nature Genetics, detail how sensory hair cells in the ear - the cells largely responsible for hearing - develop unique shapes that enable the perception of sound.

Young breast cancer sufferers need more fertility advice before treatment

According to new research led by the University of New South Wales (UNSW), Australia, 25% of young breast cancer sufferers say that there was no discussion of fertility issues at the time of diagnosis, despite the possibility of infertility after treatment.
