A web service differs from a web site in that a web service provides information consumable by software rather than humans. As a result, we are usually talking about exposed JSON, XML, or SOAP services. Web services are a key component in mashups.
Neutropenia is an abnormally low number of neutrophils (a type of white blood cell) in the blood. Neutropenia, if severe, significantly increases the risk of life-threatening infection. Neutropenia is often a side effect of the treatment of cancer with chemotherapy or radiation therapy.
Infections may cause a temporary decrease in white blood cell count, a condition known as leukopenia. In a severe bacterial infection, white blood cells that normally circulate in the bloodstream migrate to the site of the infection in large numbers, leading to a low white blood cell count in the blood.
