Gene clue to antibiotics

...sis. So this research may reveal insights into the biology of this important disease, which still poses a major threat to humanity....

Comprehension of taste receptor

...said Professor Laing. Recent advances in molecular biology have allowed researchers to work with larger amounts of cloned receptors, rather than with the small numbers available in the tongue.The lumps on the tongue that are often called 'taste buds' are actually papillae. These have several pores in them, w...

Defeating colon cancer

...pplement. The study may also shed new light on the biology of colon cancer, stimulating further research....

Fossil teeth and human development

... author Alan Walker, professor of anthropology and biology at Penn State University, said in a news release. "Teeth grow in an incremental manner like trees or shells, preserving a record of their growth with daily marks along the prisms that make up the enamel." By making thin sections of modern and fossil...

A question on study of Adult Stem Cell

..., professor and chairman of developmental and cell biology at the University of California, Irvine, told UPI.... systems to see whether is it relevant to (animal) biology or a tissue culture phenomenon," Mark Sussman of the Division of Molecular Cardiovascular Biology at...

Elevating Manganese Levels hold back HIV

...e. According to Jef Boeke, professor of molecular biology at Hopkins University, if drugs could be grown that increase manganese levels, it would be a innovative approach to treating HIV. Boeke said his team currently is looking for drugs that do just that. The higher levels of manganese in yeast were cause...

Survival rates in breast cancer patients improved with "Dose Dense Chemotherapy"

... dense chemotherapy could advance knowledge of the biology of breast cancer and how best to treat it. He also added that further confirmed studies would affect the care of thousands of patients throughout the world with breast cancer and perhaps, eventually, other diseases. Researchers also hypothesize that...

Genetic mutation to the 'fountain of youth' discovered

.... Guiseppe Attardi, Caltech professor of molecular biology and an author of the study said that this key mutation shifts the site at which mitochondrial DNA starts to replicate, and perhaps that may accelerate its replication, allowing the individual to replace damaged molecules faster....

Germs to blame for bad breath

...erature. Dr Israel Kleinberg, chairman of the oral biology and pathology department at the State University of New York at Stony Brook's dental school suggested that environmental differences could also be the reason for the different types of bacteria in the mouth. Paster suggested that halitosis can be red...

Wearable Body Monitoring

...ealth care what the compound microscope was to the biology of disease." Unobtrusive wearable body monitoring,is a simple device worn on the body, such as a band around the arm, which measures a number of physiological levels.This includes time spent lying down or sleeping, time spent doing physical activity,...

Common Plant Triggers Asthma

...s say this type of time lag is consistent with the biology of allergens. They also say this surge of respiratory problems was not associated with the amount of air pollutants. Study authors conclude there is a marked relationship with two popular plant pollens and their implication in the high levels of ast...

Better Diet Even Late in Life May Prolong It

...tridge, a professorial fellow in the department of biology at University College London. Partridge says it's impossible to know from this study if cutting back on calories could extend life in humans. However, she adds, "lifestyle interventions started as late as middle or old age may be beneficial." For t...

Even mid-life diet change can extend life

...y of California, Davis, researcher who studies the biology of aging, said the Partridge study is "important to the field," but does not provide final answers about the true effects of restricted diets. He said that fruit flies and other animals on restricted diets tend to stop reproducing. In mammals, for...

How a man's mind really works

...les. Culture plays a part, but Gurian argues that biology matters much more than previously realized."The science has been crucial. Wherever I go, I start by showing PET scans and people can see for themselves the differences between the male and female brain. I think that alters life and marriages," said G...

Rat Genetic Code Mapped

...yed a valuable role in efforts to understand human biology and to develop new and better drugs. Now, armed with this sequencing data, a new generation of researchers will be able to greatly improve the utility of rat models and thereby improve human health. Researcher say that as they build upon the founda...

Mutations in NOTCH1 cause an early developmental defect in the aortic valve

...g, assistant professor of pediatrics and molecular biology and lead author of the study. Children’s with aortic valve defects develop early calcification of their aortic valves which leads to severe heart disease in their adulthood. Aortic valve disease is the third most common cause of heart disease in ad...

Gene-Nanoparticle Gene Transfer Is Better Than Viral Vector Transfer System

... experimental, non-viral techniques to study brain biology and new therapies to address some of the most debilitating human diseases." Viral vectors for gene therapy always carry with them the potential to revert back to wild-type, and some human trials have even resulted in fatalities. Viral vectors can be...

Revolution in Genetics to Open Avenues for Treating Cancer

...unting women. Our improved understanding of cancer biology and genetic basis of cancer have made the finding possible. It is not only an exciting advance towards understanding how breast cancer develops, but also opens up new vistas that could lead to discovery of genes linked to the disease. Thanks to the...
