A study has unveiled a previously unrecognized role for an essential nutrient in shaping the cellular landscape for one of the body's first lines of defense against infection, immune cells called macrophages. The findings identifying a role for the nutrient choline under normal conditions and in response to an intestinal worm infection in mice could potentially have significant implications for other models of human infection, perhaps even cancer immunity. Dr. Morgan Fullerton explains that by blocking a specific part of metabolism the research team saw an unexpected defect emerge in macrophages—sentinel cells that are one of the immune system's star...

Choline, an essential nutrient found in foods including eggs, broccoli, beans, meat and poultry, is a vital ingredient for human health. A study explores how a deficiency of dietary choline adversely affects the body and may be a missing piece in the puzzle of Alzheimer's disease. It's estimated that more than 90% of Americans are not meeting the recommended daily intake of choline. The current research suggests dietary choline deficiency can have profound negative effects on the heart, liver and other organs. Lack of adequate choline is also linked with profound changes in the brain associated with Alzheimer's disease. These...

At that stage, production was heavily reliant on the import of precursor chemicals from foreign suppliers. In 1982, early in the Iran-Iraq War, the Iraqis used riot control agents to repel Iranian attacks. They progressed to the use of CW agents in mid-1983 with mustard, and in March 1984 with tabun (the first use ever of a nerve...
