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.
A low white blood cell count may also indicate the presence of a serious bacterial, viral, or fungal infection that attacks the immune system, such as the human immunodeficiency virus . Some congenital disorders, including lupus and myelofibrosis, cause the body to attack its own defense system, depleting bone marrow and white blood cells.
