Heterocyclic amines in cooked meats

Research has shown that cooking certain meats at high temperatures creates chemicals that are not present in uncooked meats. A few of these chemicals may increase cancer risk. For example, heterocyclic amines (HCAs) are the carcinogenic chemicals formed from the cooking of muscle meats such as beef, pork, fowl, and fish. HCAs form when amino acids (the building blocks of proteins) and creatine (a chemical found in muscles) react at high cooking temperatures. Researchers have identified 17 different HCAs resulting from the cooking of muscle meats that may pose human cancer risk. more  

Cancer and the environment

This booklet was created by scientists at the National Cancer Institute (NCI) and the National Institute of Environmental Health Sciences (NIEHS) in response to many public requests for information. The content has been guided by responses from a series of focus groups* that were conducted prior to producing the booklet. People from local communities throughout the country participated in these groups. more

Putting science to service - The study of hypertension

Why do some people with hypertension have a stroke and some don't? Why kidney failure for some and not others? Gary H. Gibbons, M.D., a cardiologist who directs NIH-funded research at the Morehouse School of Medicine in Atlanta, aims to find out. He has the tools to answer those questions and help African Americans and other minority groups whose hypertension is more likely to lead to stroke and kidney failure. more  

CDC recommends meningococcal vaccine for adolescents and college freshmen

The Centers for Disease Control and Prevention (CDC) now recommends routine vaccination of children 11-12 years old, previously unvaccinated adolescents at high school entry, and college freshmen living in dormitories with the newly licensed meningococcal conjugate vaccine (MCV4). The new recommendation is designed to help achieve vaccination among those at highest risk for meningococcal disease. As the vaccine supply increases, CDC hopes, within three years, to recommend routine vaccination all adolescents beginning at 11 years of age. more

Information for patients: What is meningitis?  

Meningitis is an infection of the fluid of a person's spinal cord and the fluid that surrounds the brain. People sometimes refer to it as spinal meningitis. Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment differ. Viral meningitis is generally less severe and resolves without specific treatment, while bacterial meningitis can be quite severe and may result in brain damage, hearing loss, or learning disability. For bacterial meningitis, it is also important to know which type of bacteria is causing the meningitis because antibiotics can prevent some types from spreading and infecting other people. Before the 1990s, Haemophilus influenzae type b (Hib) was the leading cause of bacterial meningitis, but new vaccines being given to all children as part of their routine immunizations have reduced the occurrence of invasive disease due to H. influenzae. Today, Streptococcus pneumoniae and Neisseria meningitidis are the leading causes of bacterial meningitis. more
