Medical Science Strides-No Guarantee For Pre-Mature Babies

...ikely to be girls than boys, and they are all born small for gestational age, often because their mothers had pregnancy-associated high blood pressure. A normal-size fetus at just 20 weeks' gestation weighs 11 ounces, at which point the organs would be too immature for survival outside the womb. Another ...

Advancement in Gene Associated With Colon Cancer

... having simultaneously found their way to the same small area of chromosome 8, called 8q24, in the search for colon cancer genetic links. The fact that these studies were performed among other populations around the world suggests that this one genetic marker is highly influential across ethnic groups. T...

Folicacid Fortification Very Beneficial

... transformation of benign growths into cancers, or small cancers into larger ones, he says. Second, the fact that a synthetic form of folate is used for fortification may be important, suggests Mason. As the total amount of folic acid ingested increases, the mechanism that converts folic acid to methylte...

Reduction in Drug Costs

...r the rule was introduced than before, though this small difference may have been due to chance. The fact that three-quarters of patients were still not getting thiazides indicates how hard it is to change what doctors prescribe.

Indian Luxury Hotel Boss Calls for Major City Clean-up

...the five million people who travel annually to the small Gulf Emirate of Dubai. The reason, he said, was because too many potential tourists are put off by the country's shabby airports, pot-holed roads, frequent power cuts and rubbish-filled cities. "In most cities, people can't get anywhere on time a...

Contamination of the Environment by Antibiotics Fed to Livestock

...e adverse impacts of consuming plants that contain small quantities of antibiotics are largely unknown. Consumption of antibiotics in plants may cause allergic reactions in sensitive populations, such as young children. There is also concern that consuming antibiotics may lead to the development of antimic...

Stem Cells Research in Parkinsons Disease

... (PNAS). That NIH-funded study showed that only a small number of stem cells turned into dopamine-producing cells not enough to improve the primates function by replacing missing neurons. Instead, some stem cells turned into astrocytes, a supportive brain cell that produces neuron-nourishing chemicals. ...

WBC Selective About Sugar

... the surface of fungi. This sugar comprises just a small fraction of the fungal cell wall, much less than another sugar with a slightly different chemical conformation called beta-1,3-glucan. Because the scarce form of the sugar elicits a much stronger reaction from immune cells than the abundant one, it a...

Researchers Develop First Mouse Model of Lung Transplantation

...on using a nonphysiological mouse model in which a small section of trachea from one mouse was transplanted under the skin of another. Although it was simple to create, the model did not accurately mimic lung transplantation. It was a very artificial model that had little to do with reality. We think th...

Kaposi Sarcoma Arise from Multiple Cells

Kaposi sarcoma, which is often associated with AIDS, primarily affects the skin. But as the disease progresses, it can move to the lymph nodes and internal organ...

Cell Toxin Inhibits Survival Protein in Cancer Cells

...and colleagues set up screening assays to look for small molecules or compounds that are selectively toxic to cells that over express Bcl-2 proteins. Higher expression of the target protein made cells more sensitive to the 2-Methoxy antimycin inhibitor. This is called a gain of function mechanism and is ...

As a part of the study the researchers analysed the preference for morning or evening activities among a group of 111 boys and girls aged 8 to 13. They then collecte...

Neoprene Sleeve in Anterior Cruciate Ligament Surgery

He notes that the study was not designed to test whether using a neoprene sleeve was better than using nothi...
