New database about a group of genes associated with multidrug resistance in cancerous tumors

Scientists at the National Cancer Institute, have created a database of information about a group of genes associated with multidrug resistance in cancerous tumors.

Organ transplant recipients infected with West Nile virus develop more severe neurological illness

West Nile virus is an infection which in the last three years has had a significant impact in the United States. The virus is spread from birds to humans via mosquito bites. Symptoms include headache, fever and disorientation, and the disease can cause serious illness in a small percentage of infected people.

Scientists visualise protein complex responsible for looking after out of shape proteins

The structure of the chaperonin complex of the bacteria Thermus thermophilus reveals clues about how the important molecule may do its job of folding new or damaged proteins within cells.

The prion appears to function as an evolutionary stepping stone

“This prion,” explains Lindquist, “has a capacity to hide and release genetic information throughout the entire genome that can contribute to new traits in a complex way.”

Strep throat, scarlet fever and other disorders appears to use a single wasplike "stinger" to spread infection

The bacterium responsible for strep throat, scarlet fever and other disorders appears to use a single wasplike "stinger" to spread infection, according to surprised microbiologists at Washington University School of Medicine in St. Louis.

Study to determine how people with rheumatoid arthritis evaluate improvements in disease symptoms

The study will examine how much of an improvement in pain, stiffness, function and other symptoms is needed before patients consider the change important.

Lack of a gene called LBP-1a in the embryo prevents normal growth of blood vessels in the placenta

The lack of a gene called LBP-1a in the mouse embryo prevents normal growth of blood vessels in the placenta. This finding suggests that a similar defect in humans could play a role in fetal growth retardation, infant mortality and spontaneous abortion.

New gene-silencing technique

A new gene-silencing technique that takes place in the nucleus of human cells, has been demonstrated by researchers at the University of California, San Diego (UCSD) School of Medicine and the VA San Diego Healthcare System.

New clinical study to determine how people with rheumatoid arthritis evaluate improvements in disease symptoms

A new clinical study to determine how people with rheumatoid arthritis (RA) evaluate improvements in disease symptoms will be carried out by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the Department of Health and Human Services' National Institutes of Health.

Hormone previously identified in the venom of the green mamba snake may play role in stroke research

A Mayo Clinic research team is focusing on a hormone previously identified in the venom of the green mamba snake for the role it may play in a dangerous blood vessel narrowing in stroke patients that can lead to a second stroke, reduced blood flow and brain damage.

Epilepsy, new therapeutic possibilities

To date epilepsy research has mainly concentrated on the transmission of the nerve cell signals to what are known as the synapses.

Chemotherapy aimed at both cancer cells and their genetically normal cellular 'microenvironment' might improve the success of breast cancer treatment

In the first comprehensive survey of gene activity in each cell type composing normal and malignant breast tissue, scientists at Dana-Farber Cancer Institute have identified genes in non-cancerous supporting cells that can spur the growth of breast cancer cells.

Russian scientists incorporate HIV antigen into a tomato

Russian scientists are currently creating a pleasant and harmless vaccine, and edible one at that. So far, they managed to incorporate the protein gene – HIV antigen in tomatoes. The research is supported by International Science and Technology Center.

Targeted therapeutics capable of preventing or limiting the metastasis of skin cancer

An international team of scientists has identified an important molecular link involved in the spread – or metastasis – of melanoma to other organs such as the lungs.

Research into hay fever and temperature of the nose rises helps determine how reliable and effective anti-allergic agents are

In an attack of hay fever, the temperature of the nose rises. Effective medication prevents this too. An infrared camera provides non-contact images of the changes. Researchers can use these images to determine how reliable and effective anti-allergic agents are.

New minimally invasive surgery - flexible transgastric peritoneoscopy, or FTP

Surgeries performed with specialized medical devices requiring only small incisions, called laparoscopic surgery, have many advantages over traditional open surgery, including less pain, fewer complications and quicker recoveries.

Protein controls acid in cells by direct detection of volume changes

A protein responsible for regulating acid levels within cells - and pumping out acid accumulated in cardiac cells after a heart attack - activates in direct response to changes in a cell's volume, according to a new study by researchers at UT Southwestern Medical Center at Dallas.
