Can the tonsils influence oral HIV transmission?
Current research demonstrates that the tonsils may possess the necessary factors to act as a transmission site for the spread of HIV.   view more (2007-07-26)

Free radical scavenging is defective in periodontal (tooth loosening) disease
The capacity to mop up harmful oxygen free radicals seems to be reduced in people with periodontal disease, finds research in Molecular Pathology. Periodontal disease affects between 10 and 15% of people worldwide. A leading cause of tooth loss, it develops as a result of bacterial infection from a... view more (2002-11-22)

UCSD Research May Lead to Targeted Treatment for Asthma Sufferers
The bronchial tubes of a patient with severe asthma can become scarred due to repeated episodes of allergic inflammation in the airways. The scarring results in blocked airways, excessive production of mucus, and shortness of breath.   view more (2005-11-29)

Scripps Research Scientists Discover New Key to Pulmonary Edema in Respiratory Distress Syndrome
Physiology is sometimes a crossroads where many different paths converge. Such is the case with acute respiratory distress syndrome, a severe and often fatal condition also known as adult respiratory distress syndrome or simply "shock lung."   view more (2005-06-30)

New study finds how cells with damaged DNA alert the immune system
Research led by biologists at the University of California, Berkeley, has found that damage to a cell's DNA sets off a chain reaction that leads to the increased expression of a marker recognized by the body's immune system.   view more (2005-07-05)

Peptide discovered in scorpion venom may hold key to secretory diseases
Researchers have discovered a peptide in scorpion venom that may hold the key to understanding and controlling cystic fibrosis and other secretory diseases.   view more (2008-02-15)

UGA researchers one step closer to cancer vaccine
When cells become cancerous, the sugars on their surfaces undergo distinct changes that set them apart from healthy cells. For decades, scientists have tried to exploit these differences by training the immune system to attack cancerous cells before they can spread and ravage the body.   view more (2007-10-30)

Signal protein shows promise for blocking tumor promoters in skin cells
A protein with the ironic name "Srcasm" can counteract the effects of tumor-promoting molecules in skin cells, according to new research by investigators at the University of Pennsylvania School of Medicine.   view more (2006-11-06)

Links between DNA damage and breast cancer studied
Researchers from the Pacific Northwest Research Institute (PNRI) and the National Institute of Standards and Technology (NIST) have uncovered a pattern of DNA damage in connective tissues in the human breast that could shed light on the early stages of breast cancer and possibly serve as an early... view more (2006-08-07)

Neuronal regulators offer potential targets for cancer
Being too brainy can be a bad thing in a junior high cafeteria, where the social hierarchy favors other traits. "Braininess" also causes problems for cells.   view more (2008-03-20)

Cystic fibrosis research could benefit from multi-functional sensing tool
Researchers are using an innovative, multi-functional sensing tool to investigate adenosine triposphate (ATP) release and its role in cystic fibrosis.   view more (2006-03-27)

M.D. Anderson-led team reports possible key to autoimmune disease
A human peptide that acts as a natural antibiotic against invading microbes can also bind to the body's own DNA and trigger an immune response in the absence of an infection, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in an early online... view more (2007-09-17)

Carbon monoxide protects lung cells against oxygen-induced damage
Researchers at the University of Pittsburgh have demonstrated that low-dose carbon monoxide administered in conjunction with oxygen therapy markedly inhibits oxygen-induced damage to lung cells.   view more (2007-01-19)

Double binding sites on tumor target may provide future combination therapy
Researchers from the University of Pennsylvania School of Medicine and colleagues at Merck Serono Research in Germany have found that two drugs bind to receptor sites on some tumors in different places at the same time, suggesting the possibility of a new combination therapy for certain types of... view more (2008-04-09)

Experimental Technique at GUMC Offers Real-Time Analysis of Breast Cancer Biopsies
A sophisticated microscope that offers a "real-time" 3-D analysis of tissue samples might, in the future, reduce the number of needle biopsies traditionally needed from women suspected of having breast cancer, according to recent research published at Georgetown University Medical... view more (2007-11-14)

Gold nanoparticles show potential for noninvasive cancer treatment
Researchers from the University of California, San Francisco and Georgia Institute of Technology have found a new way to kill cancer cells. Building on their previous work that used gold nanoparticles to detect cancer, they now are heating the particles and using them as agents to destroy malignant... view more (2005-10-10)

From sow’s ear to new skin – new treatments for old wounds
Sterilised, cell-free pigskin* is just one of the products being developed by scientists to help the body recover from injury or disease without scarring or forming chronic, non-healing wounds. The material helps the natural healing process by acting as a matrix over which skin cells are encouraged... view more (2001-08-30)

True cancer-causing genes revealed by new technique, say Stanford researchers
Often cancer research goes like this: study cancerous cells in a lab dish, find mutations that appear in many of the samples, develop drugs to target proteins made by the mutated genes, and voila, new chemotherapy drugs are born. Or at least that's the hope.   view more (2005-06-13)

Stomach stem cell discovery could bring cancer insights
Scientists have identified and described stem cells specific to several tissues and organs of the body - key master cells that give rise to the specialized cell types characteristic of that organ.   view more (2007-10-04)

Unexpected role: EGFR protects cancer cells from starving
A growth factor receptor found abundantly on the surface of cancer cells and long known to fuel cancer growth also protects tumor cells from starvation by a newly identified mechanism.   view more (2008-05-06)

Could skin cells become brain cells? (p 172)
Results of an experimental study in this week's issue of THE LANCET highlight how adult skin cells can be made into precursor nerve cells, with potential implications for the future treatment of neurodegenerative disorders such as Parkinson's disease. Ethical and practical considerations limit the... view more (2004-07-07)

Researchers develop new method to test for lung cancer
Researchers from Boston University School of Medicine have developed a new "clinicogenomic model" to accurately test for lung cancer.   view more (2008-04-02)

Scientists take next step in understanding potential target for Ovarian cancer treatment
A traffic cop protein in the cell may have an even more important role: transporting a messenger protein that tells components in the nucleus to stop cell growth. The discovery of this additional role may lead to diagnostic tools and earlier treatments for ovarian cancer.   view more (2007-07-17)

Subtle changes in normal genes implicated in breast cancer
Using a super-efficient method they invented to search for a type of cancer-related change in all genes of a cell, Dana-Farber Cancer Institute researchers have discovered new evidence about how the "microenvironment" of breast cancers helps drive the cancers' growth and migration.   view more (2005-07-14)

First comprehensive genomic study of common cold reveals new treatment targets
Today, scientists from Procter & Gamble (P&G), the University of Calgary and the University of Virginia announced results from the first study to examine the entire human genome's response to the most common cold virus, human rhinovirus.   view more (2008-10-27)
