A simple spit test could predict cancers

In future scientists say, a test as simple as spitting into a collection tube or cup might be a screening test for breast cancer and the early detection of other tumours.

Alarming trends in sexually transmitted diseases (STDs) among America's young people

A study by ASHA, sponsored by Roche Diagnostics of Indianapolis, Indiana is being released in conjunction with April's STD Awareness Month and demonstrates that the incident rate of STDS in youth (ages 15-24) have increased dramatically in recent years.

CDC experts sent to Angola to help with Marburg epidemic

In an effort to control the Marburg virus outbreak in Angola, Health officials from the Centers for Disease Control and Prevention in Atlanta will assist the World Health Organization by going to Angola to help with outbreak investigation, infection control and laboratory diagnosis of the disease.

DNA sequencing made portable and faster by "colour-blind" technology

Researchers at Baylor College of Medicine (BCM) and Rice University have developed a"colour-blind" method of fluorescence detection which could open new doors that would take DNA sequencing to the patient's bedside, the doctor's office and even the scene of a crime or a battlefield.

Test that will prevent the needless loss of the thyroid gland in people with the noncancerous condition

New research suggests that physicians can distinguish between a type of thyroid cancer and an identical-looking, non-cancerous thyroid condition by simply determining the activity of three genes.

DNA weak links may provide clues to cancer biology

The chromosomes of mammals, including humans, contain regions that are particularly prone to breaking under conditions of stress and in cancer. Now, new research by geneticists at Duke University Medical Center finds that yeast cells also contain such weak links in DNA and begins to reveal the molecular characteristics of these links that might help to explain them.

Finding may open new horizons for understanding the initiation of chemically induced cancers

A team from the chemistry and biology departments of New York University, in collaboration with Memorial Sloan Kettering Cancer Center (MSKCC), has uncovered a conformational switch - a change in shape in a carcinogen-damaged DNA site - in tumor suppressor genes altered by a known cancer-causing chemical found in cigarette smoke.

New findings on the regulation of cellular growth

A greatly increased synthesis of new proteins is one of the first and most important events that occur in both normal and tumour cells upon growth stimulation.

Ebola virus outbreaks linked to infected wild animal carcasses

All recent Ebola virus outbreaks in humans in forests between Gabon and the Republic of Congo were the result of handling infected wild animal carcasses, according to a study by the Wildlife Conservation Society (WCS) and its regional partners

New technique can greatly facilitate the development of vaccines against infectious diseases such as smallpox, malaria and tuberculosis

Because the new technique can synthesize a large number of proteins very quickly, it has potential to accelerate vaccine development, particularly crucial in the fight against bioterrorism.

Sequencing of human genetic code promises to usher in a new era of genetic medicine

The ability of molecular biologists to sequence the human genetic code promises to usher in a new era of genetic medicine, but that doesn’t mean science can accurately read personal genetic codes.

Prevalence of occult HBV in hemodialysis patients is 4 to 5 times higher than standard HBsAg testing would suggest

Some kidney dialysis patients contract hepatitis B virus (HBV) during the course of their treatment, possibly from other members of the dialysis population with occult HBV.

New approaches for the treatment of chronic hepatitis C

Data from two ongoing studies testing new approaches for the treatment of chronic hepatitis C was presented at the annual meeting of the American Association for the Study of Liver Diseases (AASLD) this afternoon.

New rapid gonorrhea test that does not require collection

Potential antimicrobial resistance in the bacteria that cause gonorrhea can be detected without culturing the organism, thanks to a rapid test developed by researchers at Johns Hopkins.

Grant to develop high speed DNA sequence reader

Sequencing of the human genome is one of the major scientific advances of our time. But with 3 billion base pairs, initial sequencing of the human genome took 11 years and cost $1 billion to complete in 2002. Today, it costs up to $50 million to sequence 3 billion base pairs.

New role for a key protein involved in muscle contraction

Overturning a scientific stereotype, researchers at the University of Illinois at Chicago have discovered a new role for a key protein involved in muscle contraction and shown it is present not just in the cytoplasm of cells but in the nucleus as well.

Tabletop DNA test laboratory cuts disease diagnosis down to 30 minutes

British scientists have developed a tabletop DNA test laboratory that can cut the diagnosis of disease and infection from hours to 30 minutes. This new test laboratory will soon begin trials in UK hospitals.

Molecule that helps DNA replicate may make good target for cancer therapy

In order to divide, cells must first replicate their chromosomes. Cells use an array of proteins to accomplish the job, including a large enzyme complex that synthesizes new strands of DNA.
