Health effects of passive somking studied in first-of-a-kind clinical study

Until bans on in-flight smoking took effect, beginning in 1988, flight attendants were regularly exposed to secondhand smoke.

UK scientists reverse symptoms of mad cow disease

The researchers at University College, London, believe they have found a way to treat the disease in humans as long as it is detected before it has done harm to a large number of brain cells.

Different treatments may be needed for chronic asthma, depending on whether it results from allergies or lung infections

Researchers have now identified a particular gene that influences how severe a M. pneumoniae infection may be, which in turn suggests that a different strategy might be needed for treating asthma resulting from this and similar lung infections rather than allergies.

Natural fibre may help overweight achieve a healthy body weight

It sounds almost too good to be true, but Dr. Raylene Reimer, a researcher at the University of Calgary, Faculty of Kinesiology, believes she may have found an important weapon in the war against obesity.

Scientists test technique for identifying newly recognized DNA variations that may influence disease risk

Rather than focus on errors and alterations in DNA sequence, the new technique highlights variations in the number of copies of a particular gene.

Effects of nanotechnology on health and environment

University of Florida engineering student Maria Palazuelos is working on nanotechnology, but she's not seeking a better sunscreen, tougher golf club or other product - the focus of many engineers in the field.

Gene produces springy protein keeping nerve cells flexible

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

Nanocarrier stimuli-activated gene delivery

One approach to developing tumor-specific drug delivery agents is to create nanomaterials that release a therapeutic payload only after reaching their intended target.

FoxOs shown to be potential new targets for cancer drugs

In an elegant, multiple-gene knockout experiment, a team of Boston scientists has discovered that a trio of molecules, called FoxOs, are fundamentally critical in preventing some cancers, maintaining blood vessel stability, and in keeping blood-forming stem cells healthy.

SH2B1 protein plays a key role in controlling body weight, response to insulin and leptin

A single protein in brain cells may act as a linchpin in the body's weight-regulating system, playing a key role in the flurry of signals that govern fat storage, sugar use, energy balance and weight, University of Michigan Medical School researchers report.

RNA used to turn on genes to alleviate disease

A new technique that employs RNA, a tiny chemical cousin of DNA, to turn on genes could lead to therapeutics for conditions in which nudging a gene awake would help alleviate disease, researchers at UT Southwestern Medical Center say.

Small molecule targets weak mRNA

A new strategy for fighting cancer aims to make its genes get lost in translation, according to a report in the January 26, 2007, issue of the journal Cell.

Micro molecules can distinguish pancreatic cancer from normal and benign pancreatic tissue

The study examined human pancreatic tumor tissue and compared it to nearby normal tissue and control tissue for levels of microRNA (miRNA).

Minor mistake in protein production at the cellular level may lead to serious neurological diseases

But exactly how the cell avoids such mistakes has remained unclear until now. Researchers at Ohio State University found the mechanism that prevents such errors, and explain their findings in the Proceedings of the National Academy of Sciences.

50% of Americans have gene that affects how body burns sugar

A recent study by a Saint Louis University researcher confirms findings that about half of the U.S. population has a version of a gene that causes them to metabolize food differently, putting them at greater risk of developing diabetes.

Scientists find surprising way of switching off a gene involved in cell division

Scientists at the University of Oxford have identified a surprising way of switching off a gene involved in cell division.

Simple diagnostic test detects genetic signs of lung cancer in sputum

DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers.

Nanoparticles yield delivery tools for therapeutic nucleic acids

Cancer researchers hold great hope that nucleic acid-based therapeutics, such as anticancer genes, antisense oligonucleotides, and small interfering RNA (siRNA) molecules, will prove to be powerful antitumor agents.

Variations in SORL1 gene may factor in development of Alzheimer's disease

Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, and was supported in part by the National Institutes of Health (NIH).

Stem cell research discovery could mean 'big things' for cancer

A new discovery in stem cell research may mean big things for cancer patients in the future. Gary Van Zant, Ph.D., and a research team at the University of Kentucky published their findings in Nature Genetics.
