A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

New technique boosts success rates with artificial insemination

In future a new method could help some couples who are childless against their will. The microscopic procedure significantly improves the success rate of 'ICSI' (intracytoplasmic sperm injection).

Early detection of pediatric thyroid cancer critical

Efforts to treat pediatric papillary thyroid cancer are greatly improved by detecting the disease as early as possible, making the patient's age the most important factor in determining a prognosis, according to new research published in the February 2008 issue of the journal Otolaryngology Head and Neck Surgery.

Novel drug romiplostim significantly improves treatment of dangerous blood disorder

Two clinical trials of the novel drug romiplostim (Nplate) show that it significantly improved platelet levels in patients with chronic immune thrombocytopenic purpura (ITP), a hematologic disorder that can cause uncontrolled bleeding.

New discoveries on what does and doesn't affect immune system

Scientists know that a number of factors can affect the body's immune system: poor diet, certain steroids, chronic stress. Now researchers at Michigan State University have discovered that an appetite-controlling hormone also affects the immune system, while natural versions of certain steroids do not.

Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.
