input: Malachite green

Numerous niche applications exploit the intense color of MG. It is used as a biological stain for microscopic analysis of cell biology and tissue samples. In the Gimenez staining method, basic fuchsin stains bacteria red or magenta, and malachite green is used as a blue-green counterstain. Malachite green is also used in endospore staining, since it can directly stain endospores within bacterial cells; here a safranin counterstain is often used. Malachite green can also be used as a saturable absorber in dye lasers, or as a pH indicator between pH 0.2--1.8. However, this use is relatively rare. Leuco-malachite green (LMG) is used as a detection method for latent blood in forensic science. Hemoglobin catalyzes the reaction between LMG and hydrogen peroxide, converting the colorless LMG into malachite green. Therefore, the appearance of a green color indicates the presence of blood.

input: Huntington's disease

Huntington's disease (HD), also known as Huntington's chorea, is an inherited disorder that results in death of brain cells. The earliest symptoms are often subtle problems with mood or mental abilities. A general lack of coordination and an unsteady gait often follow. As the disease advances, uncoordinated, jerky body movements become more apparent. Physical abilities gradually worsen until coordinated movement becomes difficult and the person is unable to talk. Mental abilities generally decline into dementia. The specific symptoms vary somewhat between people. Symptoms usually begin between 30 and 50 years of age, but can start at any age. The disease may develop earlier in life in each successive generation. About eight percent of cases start before the age of 20 years and typically present with symptoms more similar to Parkinson's disease. People with HD often underestimate the degree of their problems.

input: Juris Doctor

The Juris Doctor degree (J.D. or JD), also known as the Doctor of Jurisprudence degree (J.D., JD, D.Jur. or DJur), is a graduate-entry professional degree in law and one of several Doctor of Law degrees. It is earned by completing law school in Australia, Canada and the United States, and some other common law countries. It has the academic standing of a professional doctorate in the United States, a master's degree in Australia, and a second-entry, baccalaureate degree in Canada, (in all three jurisdictions the same as other professional degrees such as M.D. or D.D.S., the degrees required to be a practicing physician or dentist, respectively).
