Twenty-five million Americans suffer from ulcers. An ulcer is a sore or hole in the lining of the stomach or duodenum (the first part of the small intestine). People of any age can get an ulcer and women are affected just as often as men.
Helicobacter pylori (H. pylori) is a bacterium that lives on the lining of the stomach. Although we used to think that spicy food, acid, and stress were the major causes of ulcers, we now know that nine out of ten ulcers are caused by H. pylori. Medicines that reduce stomach acid may make you feel better, but your ulcer may come back. Here's the good news: Since most ulcers are caused by this bacterial infection, they can be cured with the right antibiotics.
A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. The realization that pathogens can produce slowly progressive chronic diseases has opened new lines of research into Alzheimer's disease.
Researchers at Georgia Tech have developed a narrowband filter mosaic that will expand the uses and functionality of multispectral imaging-a technology that enables subsurface characterization.
The death toll in China from enterovirus 71 (EV71) has risen to 39 with the deaths of five more children; EV71 belongs to the same family as the polio virus and is a strain of hand, foot and mouth disease (HFMD).
Vegetables that are rich in nitrates protect the stomach from damage. This takes place through conversion of nitrates into nitrites by the bacteria in the oral cavity and subsequent transformation into biologically active nitric oxide in the stomach. The Swedish researcher Joel Petersson has described the process, which also means that antibacterial mouthwashes can be harmful for the stomach.
Health care in the United States is expensive, but its funding is crucial because it also is a major contributor to the economy and can better lives, according to an essay appearing in the June 2008 issue of the Journal of the American Society Nephrology (JASN). Because of the cost of health care, this is not time to shrink the budget at the National Institutes of Health, which funds medical research that leads to potentially curative therapy.
A large study by scientists in the U.S. has revealed that the long-term use of ibuprofen may reduce the risk of a person developing Alzheimer's disease.
As the number of people in China affected by a deadly intestinal virus continues to rise, Chinese authorities have been accused of trying conceal the outbreak
Based on research using a new mouse model of gastritis and stomach cancer, researchers from the Massachusetts Institute of Technology (MIT) say that prompt treatment of Helicobacter pylori (H. pylori) infections reverses damage to the lining of the stomach that can lead to cancer.
Scientists in the U.S. say an aspirin a day may afford women some protection against the most common type of breast cancer, estrogen receptor or ER-positive breast cancer.
A virus in China has which has killed 20 children and made 1,179 others ill is causing alarm.
The overall amputation rate in northern Illinois is declining due to improved care for diabetes and peripheral vascular disease, new research shows.
The U.S. Food and Drug Administration (FDA) approved a new once-a-month dose (150 mg) of Actonel (risedronate sodium) tablets for the treatment and prevention of postmenopausal osteoporosis. Actonel is approved to reduce the risk of fractures in postmenopausal women with osteoporosis.
Duke University Medical Center researchers have recently discovered that a crucial communications pathway in cells not only stops cells from making proteins, it also makes them go. The team was able to define the way in which proteins called beta arrestins (for their role in stopping signals) also turn on pathways that ultimately lead to the production of new proteins in virtually all tissues in the body.
Anticholinergic drugs, such as medicines for stomach cramps, ulcers, motion sickness, and urinary incontinence, may cause older people to experience greater decline in their thinking skills than people not taking the drugs, according to research that will be presented at the American Academy of Neurology 60th Anniversary Annual Meeting in Chicago, April 12–19, 2008.
Australia's National Drugs and Poisons Scheduling Committee (NDPSC) is apparently considering making one of the most commonly used over-the-counter (OTC) drugs available only with a prescription.
Scientists in Arizona report that minerals from clay could form the basis of a new generation of inexpensive, highly-effective antimicrobials for fighting MRSA infections that are moving out of health care settings and into the community.
Despite their reputation for deadly attacks on humans and pets, alligators are wiggling their way toward a new role as potential lifesavers in medicine, biochemists in Louisiana reported today at the 235th national meeting of the American Chemical Society.
Biochemists from Louisiana in the U.S. say blood from alligators could help fight deadly 'superbugs' and other infections.
A child spikes a high fever, sometimes as high as 104 or 105 degrees, and sometimes causing seizures.
An international team of 17 researchers from four countries has for the first time isolated from the environment and fully characterized the organism that causes Buruli ulcer.
