Inflammatory molecules released by pollen trigger allergies

How do pollen particles provoke allergic reactions? A new study in the February 21 issue of The Journal of Experimental Medicine puts some of the blame on bioactive molecules that are released from pollen. These molecules bind to immune cells and cause them to launch a typical allergy-promoting immune response. Pollen from plants exposed to air pollutants produce more of these allergy-provoking c...

Although new HIV treatments have drastically reduced the incidence of Kaposi's sarcoma in developed countries, it remains a health threat in many developing countries. Now, researchers have discovered one way that Kaposi's sarcoma ?a cancer-like viral disease traditionally associated with AIDS ?triggers severe inflammation. Don Ganem, a Howard Hughes Medical Institute (HHMI) investigator,...

FDA Announces Series of Changes to the Class of Marketed Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

The Food and Drug Administration (FDA) today announced a series of important changes pertaining to the marketing of the non-steroidal anti-inflammatory class of drugs, including COX-2 selective and prescription and non-prescription (over-the-counter (OTC)) non-selective NSAID medications. A list of these products is available on the Internet at http://www.fda.gov/cder/drug/infopage/cox2/default.h...

Researchers report new pro-inflammatory role for anti-inflammatory enzyme

Part of the immune system's pro-inflammatory response to bacterial invasion is to increase nitric oxide levels with an enzyme called inducible nitric oxide synthase. In a study published in the Journal of Biological Chemistry, scientists report that the predominantly anti-inflammatory enzyme, endothelial nitric oxide synthase, is also involved in nitric oxide production in response to infection....

B cells are required for development of epithelial cancer associated with chronic inflammation

Chronic inflammation is linked to the development of certain types of cancer, but mechanisms mediating inflammation during premalignancy are not well understood. A new research study published in the May issue of Cancer Cell identifies B lymphocytes as important regulators of premalignancy associated with chronic inflammation. The results suggest that drugs targeted against B lymphocytes or recru...

Relieve hot flashes

According to experts from the Mayo Clinic in Rochester, Minnesota Vitamin E is one of the remedy in the treatment of sufferers with hot flashes. Estrogen relieves hot flashes in most women, but concerns remain over its use in breast cancer survivors because the hormone may stimulate breast cancer growth.// The herb black cohosh seems to alleviate hot flashes and other symptoms of m...

Flaxseed fights cancer risk

A new study suggests that flaxseed lowers female hormone levels and may thereby reduce breast cancer risk.The flax plant has been used for thousands of years - the fibres to make linen and the ground seeds in bread and cereal.The seeds are rich in lignans, which resemble the female hormone oestrogen.// High levels of oestrogen are linked to breast cancer and lignans may lower levels b...

Sniff out flatulence

Scientists think they have discovered the Holy Grail of bad smells - a product that could wipe out the lingering effects of flatulence. American researchers believe the answer to the age-old embarrassment could be charcoal.

Control of inflammation

Particular cell surface molecules sense runaway inflammation and tissue damage, say researchers, Michail Sitkovsky, and his coworkers at the National Institute of Allergy and infectious Diseases (NIAID).The finding appeared in Nature.// Inflammation, tissue swelling is accompanied by pain and heat, is the body’s response to a host of insults: invasion by bacteria or viruses, injury, or re...

Safeguarding anti-inflammatory users from ulcers

Not only do these drugs relieve the symptoms of arthritis, they also protect against heart attack, stroke and maybe even Alzheimer's disease. But the NSAIDs h...
