Racial Disparity in Colon Cancer Survival Not Easily Explained

For colon and other cancers, African-Americans have lower survival rates than whites. There was a belief that racial disparity in survival following surgery for colon cancer was related to a high BMI and co-morbidity. A new study in Cancer shows how that explanation is flawed.

Researchers Track Down Protein Responsible for Chronic Rhinosinusitis with Polyps

A protein known to stimulate blood vessel growth has now been found to be responsible for the cell overgrowth in the development of polyps that characterize one of the most severe forms of sinusitis, a study by Johns Hopkins researchers suggests. The finding gives scientists a new target for developing novel therapies to treat this form of the disease, which typically resists all current treatments.

Day Care May Double TV Time For Young Children

In a new study, the amount of television viewed by many young children in child care settings doubles the previous estimates of early childhood screen time, with those in home-based settings watching significantly more on average than those in center-based daycares.

Exposure to Traffic Pollution and Indoor Allergens Multiplies Risk of Asthma in High-Risk Kids

Children who are exposed to high levels of traffic-related pollution and high levels of indoor endotoxin early in life have six times the risk of developing persistent wheezing by age three than children exposed to low levels of traffic and indoor-related pollutants, according to new research from the University of Cincinnati College of Medicine.

Fuel Oil and Traffic Pollution May Increase Risk of Respiratory Problems in Inner-City Children

Exposure shortly after birth to ambient metals from fuel oil combustion and particles from diesel emissions is associated with respiratory symptoms in young inner-city children, according to a new study by researchers at the Columbia Center for Children’s Environmental Health (CCCEH) at Columbia University’s Mailman School of Public Health.

Is Global Warming Unstoppable?

A University of Utah scientist argues that rising carbon dioxide emissions – the major cause of global warming – cannot be stabilized unless the world’s economy collapses or society builds the equivalent of one new nuclear power plant each day.

Measuring and Modeling Blood Flow in Malaria

When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells. Inside the blood cells, the parasites replicate and also begin to expose adhesive proteins on the cell surface that change the physical nature of the cells in the bloodstream.

New Cancer Target for Non-Hodgkin's Lymphoma

Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer that affects lymphocytes, or white blood cells. By exploiting this mechanism, researchers have been able to powerfully suppress tumor formation in lab testing and in animal models.
