Immunotherapy : A broad category of anti-cancer therapies

Immunotherapy, also called biologic therapy, is a type of cancer treatment designed to boost the body's natural defenses to fight the cancer. It uses materials either made by the body or in a laboratory to improve, target, or restore immune system function.

The immune system helps your body fight infections and other diseases. It is made up of white blood cells and organs and tissues of the lymph system.

Sex During Pregnancy

During the first trimester, many women report no great desire for sex because they feel tired and nauseous, but during the second trimester, “they are feeling better, there is more lubrication, and they have engorgement in the genital area,” says Monica Foreman, MD, an obstetrician at Montefiore Medical Center in the Bronx, N.Y.

This makes sex more appealing and potentially more satisfying. What’s more, most women are still fairly comfortable during second trimester because their stomach is not overly rounded yet. This is not quite true during third trimester. As the stomach grows and fatigue returns with a vengeance, sex may seem less attractive -- not to mention physically difficult during the final weeks of pregnancy.

The Importance of Medicinal Plants

Plants form the main ingredients of medicines in traditional systems of healing and have been the source of inspiration for several major pharmaceutical drugs. Roughly 50,000 species of higher plants (about 1 in 6 of all species) have been used medicinally. This represents by far the biggest use of the natural world in terms of number of species.

Most species are used only in folk medicine, traditional systems of formal medicine using relatively few (e.g. 500-600 commonly in Traditionally Chinese Medicine). Around 100 plant species have contributed significantly to modern drugs. The use of medicinal plants is increasing worldwide, related to the persistence and sometimes expansion of traditional medicine and a growing interest in herbal treatments.

FDA Approves Experimental Zika Test for Blood Donations

An experimental test to check blood donations for the Zika virus has been approved by the U.S. Food and Drug Administration.

The decision to allow use of the test in areas with active mosquito-borne transmission of the virus means that collections of whole blood and blood component donations will be able to resume in Puerto Rico, agency officials said.

"The availability of an investigational test to screen donated blood for Zika virus is an important step forward in maintaining the safety of the nation's blood supply, especially for those U.S. territories already experiencing active transmission," Dr. Peter Marks, director of the FDA's Center for Biologics Evaluation and Research, said Wednesday, March 30, 2016.
