Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

...cardiac myocytes to replace the damaged cells. To address this problem, Dr. Lough looked at the way cardiac myocytes develop in the embryo itself. In research conducted on chick embryos since 1992, his team discovered that a group of very young embryonic cells called “precardiac endoderm?sends strong signal...

HIV vaccine trial breaks ground for future research

... Group, and Peter B. Gilbert and colleagues, which address the vaccine efficacy results and the immunologic responses of the study participants. The vaccine, produced by VaxGen, was a recombinant construct of the HIV envelope glycoprotein, similar to the type of vaccine used to develop a vaccine for hepatit...

Researchers develop rapid diagnostic tool for pathogen identification

... forensic microbiology, and biodefense.?/p> To address the need for highly sensitive diagnostics, researchers built on an established method known as polymerase chain reaction that allows amplification of genetic sequences and on a technology previously used for DNA sequencing and detection of genetic po...

Bone Density Recovers After Teens Stop Injected Contraceptive

...nsity and NICHD is currently supporting a study to address this issue. The researchers measured the participants?bone mineral densities when the study began, and every six months thereafter for the next two to three years. During the course of the study, 61 women stopped using the contraceptive. The resear...

Scientists find fossil proof of Egypt's ancient climate

...uses classic earth science methods and concepts to address questions of archaeological interest. "In this particular study, we're interested in building a history of climate change through time to understand how people would have responded to dramatic shifts in climate," said Smith. "This is a major theme o...

...IB), kicked off day one (4 March) with his keynote address called ‘Predictive medicine and health research in the post-genomic era? Later on day one, Ayoade Oduola of the World Health Organisation, asked “How can we tackle the ‘genomic divide?between the developed and developing nations??Following up on thi...

Influenza vaccine uses insect cells to speed development

...ok vaccines can be developed quickly and safely to address late appearing influenza viruses and to reduce the impact of a potential flu pandemic." ...

Alcohol's effects on gene expression in the central nervous system

...f Alcoholism: Clinical & Experimental Research address the effects of alcohol on what is called "gene expression" in the CNS regions of animal models. "All of our cells have exactly the same deoxyribonucleic acid (DNA), which means they all have the same genes," explained William J. McBride, symposium o...

A comprehensive response to HIV could prevent 10 million AIDS deaths in Africa by 2020

...ical trials.Lachman believes that the vaccine will address two additional safetyconsiderations “because it is built of RNA that cannot insert itselfinto the genome, and the possibility of autoimmunity to it appears tobe low, because normal cells express very small amounts of the HER2/neugrowth protein.?...

...ate of something else, a controversial proposal to address the threat of global warming. The National Science Foundation and the U.S. Department of Energy are providing financial support. Field work got underway in July, 2004, when Wells served as chief scientist on the Kilo Moana, a research ship that left...

Spleen may be source of versatile stem cells

...Faustman's team found that a treatment designed to address theautoimmune reaction underlying type 1 diabetes actually cured thedisease in diabetic mice. Late in 2003 they reported the mechanismbehind the earlier discovery: cells from the spleens of donor mice -intended to train the diabetic animals' immune s...
