New technique for creating authentic embryonic stem cells from rats

Stem Cell Sciences plc has announced that pioneering research describing a technique for creating authentic embryonic stem (ES) cells from rats has been published in the prestigious peer-reviewed journal, Cell.

Scientists isolate genes that made 1918 flu lethal

By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.

Baby girl due soon will be minus breast cancer causing gene

A baby girl about to be born in Britain will be the first to have been screened for a breast cancer causing gene.

Vulnerability to post-traumatic stress runs in families

Earthquakes have aftershocks - not just the geological kind but the mental kind as well. Just like veterans of war, earthquake survivors can experience post-traumatic stress disorder, depression and anxiety.

Physicians perform rare surgery to restore hearing to a deaf patient

Marisela Leon, 44, has neurofibromatosis type 2 -- a rare genetic condition that causes tumors to grow on nerves in the brain or spinal cord, but most commonly on the auditory nerve. Leon lost her hearing more than four years ago when surgery to remove a tumor damaged her auditory nerve.

Patient-derived induced stem cells retain disease traits

The dying cells - the same type lost in patients with the devastating neurological disease spinal muscular atrophy - confirmed that the University of Wisconsin-Madison stem cell biologist had recreated the hallmarks of a genetic disorder in the lab, using stem cells derived from a patient.

Hexokinase-1 gene variation associated with widely used marker of blood glucose concentration

Scientists have found that genetic variation at the hexokinase-1 gene is linked to variation in the blood concentration of glycated hemoglobin, an index of long-term blood glucose concentration widely used in the follow-up of diabetes patients.

Drinkers with the ADH1C gene at greater risk of colorectal cancer

Chronic drinking is a risk factor for colorectal cancer, possibly through the effects of acetaldehyde, which is created by the alcohol dehydrogenase (ADH) enzyme.

Ancient African exodus mostly involved men

Modern humans left Africa over 60,000 years ago in a migration that many believe was responsible for nearly all of the human population that exist outside Africa today.

Researchers identify gene linked to inherited form of fatal lung disease

Researchers at UT Southwestern Medical Center have determined that a mutation in a gene known for its role in defending the lungs against invading pathogens is responsible for some inherited cases of a lethal lung disease affecting older adults. The same mutation may also be associated with lung cancer, the researchers said.

Scientists develop method for generating novel stem cells

The study, which appears in the December 18 online version of Cell Stem Cell and the January 2009 print edition of the journal, provides proof of principle that alternative sources of stem cells can be created.

New understanding of ion channels in the body

A discovery by Canada-U.S. biophysicists will improve the understanding of ion channels, akin to little 'nano-machines' or 'nano-valves' in our body, which when they malfunction can cause genetic illnesses that attack muscles, the central nervous system and the heart.

Smoking during the first trimester of pregnancy linked to oral clefts

Smoking during the first trimester of pregnancy is clearly linked with an increased risk of cleft lip in newborns.

Levels of two proteins impact survival in ovarian cancer

Levels of two proteins in a woman's ovarian cancer are strongly associated with her likelihood of survival, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Dec. 18 issue of the New England Journal of Medicine.

80% public support for genetic research and testing

The 2008 Virginia Commonwealth University Life Sciences survey shows that eight in 10 adults nationwide favor making genetic testing easily available to all who want it, and 54 percent say that the benefits of conducting genetic research outweigh the risks.

Women mostly satisfied with egg donation; some claim problems

Two-thirds of women who donated eggs to fertility clinics reported satisfaction with the process, but 16 percent complained of subsequent physical symptoms and 20 percent reported lasting psychological effects, according to the first study to examine the long-term effects of donation.

Research looks at link between normal and cancer stem cells

Scientists at St. Jude Children's Research Hospital have answered a central question in cancer biology: whether normal stem cells can give rise to tumors.

Dieting may help reduce the risk of gum disease, mostly in men

For men, especially older men, dieting may help reduce the risk of gum disease more than for women, according to a new study by researchers at the University of Maryland, Baltimore and other institutions.
