A disease is an abnormal condition of the body or mind that causes discomfort, dysfunction, or distress to the person afflicted or those in contact with the person. Sometimes the term is used broadly to include injuries, disabilities, syndromes, infections, symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts these may be considered distinguishable categories.

Pathology is the study of diseases. The subject of systematic classification of diseases is referred to as nosology. The broader body of knowledge about human diseases and their treatments is medicine. Many similar (and a few of the same) conditions or processes can affect animals (wild or domestic). The study of diseases affecting animals is veterinary medicine. Plants as well can suffer from a variety of processes such as infection, nutrient deficiency, or deleterious mutation. The study of diseases affecting plants is termed plant pathology.

Schizophrenia and Bipolar Disorder Share Genetic Roots
Wed, 01 Jul 2009 15:45:00 -0400
A trio of genome-wide studies -- collectively the largest to date -- have pinpointed a vast array of genetic variation that cumulatively may account for at least one third of the genetic risk for schizophrenia. One of the studies traced schizophrenia and bipolar disorder, in part, to the same chromosomal neighborhoods.
Imaging Technique Allows Researchers to Monitor Protein Changes in Mouse Tumors
Wed, 01 Jul 2009 12:05:00 -0400
A new imaging technique can monitor, in living mice, the HER2 protein found in above-normal amounts in many cases of breast cancer as well as some ovarian, prostate and lung cancers. This new approach, once validated in mice and pending further experiments, could provide a real-time noninvasive method for identifying tumors in humans who express HER2 and who would be candidates for targeted therapy directed against this protein. It may also provide real-time information that will help clinicians optimize treatment for individual patients. The study, published in the July 2009 issue of The Journal of Nuclear Medicine, was conducted by researchers at the National Cancer Institute (NCI) and the National Institute of Biomedical Imaging and Bioengineering, both parts of the National Institutes of Health.
Dynasty: Influenza Virus in 1918 and Today
Tue, 30 Jun 2009 09:10:00 -0400
The influenza virus that wreaked worldwide havoc in 1918-1919 founded a viral dynasty that persists to this day, according to scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. In an article published online on June 29 by the New England Journal of Medicine, authors Anthony S. Fauci, M.D., Jeffery K. Taubenberger, M.D., Ph.D., and David M. Morens, M.D., argue that we have lived in an influenza pandemic era since 1918, and they describe how the novel 2009 H1N1 virus now circling the globe is yet another manifestation of this enduring viral family.
