Technique may help stem cells generate solid organs, Stanford study shows

STANFORD, Calif. — Stem cells can thrive in segments of well-vascularized tissue temporarily removed from laboratory animals, say researchers at the Stanford University School of Medicine. Once the cells have nestled into the tissue's nooks and crannies, the so-called "bioscaffold" can then be seamlessly reconnected to the animal's circulatory system.

The new technique neatly sidesteps a fundamental stumbling block in tissue engineering: the inability to generate solid organs from stem cells in the absence of a reliable supply of blood to the interior of the developing structure.

Doctors endorse vegan and vegetarian diets for healthy pregnancies

WASHINGTON--Well-planned vegetarian and vegan diets are healthful choices for pregnant women and their children, and vitamin B12 needs can be easily met with fortified foods or any common multivitamin, say doctors and dietitians with the Physicians Committee for Responsible Medicine (PCRM). PCRM nutrition experts are available for comment in response to a new Pediatrics study showing that low levels of vitamin B12 may increase the risk for neural tube defects.

New potential therapeutic target discovered for genetic disorder -- Barth syndrome

Researchers at NYU Langone Medical Center may have discovered a new targeted intervention for Barth Syndrome (BTHS). BTHS, a sometimes fatal disease, is a serious genetic disorder occurring predominantly in males that leads to infection or heart failure in childhood.

Chantix side effects no worse with depression history

People with a likely history of depression who take varenicline (Chantix®) do not report more severe mood symptoms, medication side effects, or less success quitting smoking compared to people with no history of depression taking this drug.

Optical techniques show continued promise in detecting pancreatic cancer

EVANSTON, Ill. --- Optical technology developed by a Northwestern University professor of biomedical engineering has been shown to be effective in detecting the presence of pancreatic cancer through analysis of neighboring tissue in the duodenum, according to clinical trial results published in the journal Disease Markers.

Anti-immigrant sentiment greater in California than Texas

Los Angeles, London, New Delhi, Singapore and Washington DC (March 2, 2009) California and Texas have the largest populations of Mexican immigrants in all of the United States. A recent study, published by SAGE in the January/February issue of the Hispanic Journal of Behavioral Sciences explored what life and jobs are like for those immigrants and whether one state has higher levels of anti-immigrant sentiment than the other.

U-M researchers ID gene involved in pancreatic cancer

ANN ARBOR, Mich. — Researchers from the University of Michigan Comprehensive Cancer Center have identified a gene that is overexpressed in 90 percent of pancreatic cancers, the most deadly type of cancer.

Expression of the gene, Ataxia Telangiectasia Group D Complementing gene, called ATDC, is on average 20 times higher in pancreatic cancer cells than in cells from a normal pancreas. What's more, the gene appears to make pancreatic cancer cells resistant to current therapies.

Engineering bouncing babies, 1 at a time

As hopeful moms-to-be learn, there are important considerations to the successful implantation of a fertilized human egg. A calm environment, regular hormonal injections and the timing of the implantation can all affect the outcome of an in-vitro procedure.

Broccoli may help protect against respiratory conditions like asthma

Here's another reason to eat your broccoli: UCLA researchers report that a naturally occurring compound found in broccoli and other cruciferous vegetables may help protect against respiratory inflammation that causes conditions like asthma, allergic rhinitis and chronic obstructive pulmonary disease.

Study documents increasing prevalence of influenza A resistance to drug oseltamivir

Influenza A viruses (H1N1 subtype) that are resistant to the drug oseltamivir circulated widely in the U.S. during the 2007-2008 influenza season, with an even higher prevalence of drug resistance during the current 2008-2009 influenza season, according to a study to be published in the March 11 issue of JAMA, and being released early online because of its public health importance.

Drug-resistant influenza A virus potentially serious to high-risk patients

A mutation of the influenza A(H1N1) virus that is resistant to the drug oseltamivir may pose a serious health threat to hospitalized patients who have a weakened immune system, according to a study to be published in the March 11 issue of JAMA, and being released early online because of its public health importance.

Doubling a gene in corn results in giant biomass

University of Illinois plant geneticist Stephen Moose has developed a corn plant with enormous potential for biomass, literally. It yields corn that would make good silage, Moose said, due to a greater number of leaves and larger stalk, which could also make it a good energy crop.

Doctors call for change in how non-active TB in immigrant children treated

INDIANAPOLIS – New guidelines proposed in the March 2009 issue of the journal Pediatrics by researchers from the Indiana University School of Medicine and Riley Hospital for Children may have a major impact on how U.S. pediatricians and family physicians treat non-active tuberculosis (TB) in children who are immigrants, internationally adopted or refugees. The researchers say the strategy should improve the health of this growing number of children and save healthcare dollars.

The 2 worlds of kids' morals

Children's moral behavior and attitudes in the real world largely carry over to the virtual world of computers, the Internet, video games and cell phones. Interestingly, there are marked gender and race differences in the way children rate morally questionable virtual behaviors, according to Professor Linda Jackson and her team from Michigan State University in the US. Their research (1) is the first systematic investigation of the effects of gender and race on children's beliefs about moral behavior, both in the virtual world and the real world, and the relationship between the two.

Modern life-making women 'ignorant and ill-equipped' to cope with motherhood

The growing trend to move miles away from hometowns and family for work is leaving many women feeling 'ignorant and ill-equipped' to cope with pregnancy and childbirth.

According to a University of Warwick study of motherhood, many women do not have the support and advice they need when they have a baby because they live too far from close family.

The study also suggests the modern practice of encouraging new mothers to give birth in hospital means women often have no experience of childbirth until they have their own children.
