QUES: In 1911 arsphenamine, the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of the Institute of Experimental Therapy in Berlin. The drug was given the commercial name Salvarsan. Ehrlich, noting both the general toxicity of arsenic and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]

QUES: Phonology is a branch of linguistics concerned with the systematic organization of sounds in languages. It has traditionally focused largely on the study of the systems of phonemes in particular languages (and therefore used to be also called phonemics, or phonematics), but it may also cover any linguistic analysis either at a level beneath the word (including syllable, onset and rime, articulatory gestures, articulatory features, mora, etc.) or at all levels of language where sound is considered to be structured for conveying linguistic meaning. Phonology also includes the study of equivalent organizational systems in sign languages.

QUES: In 2012, the Pan American Health Organization (the North and South American branch of the World Health Organization) released a statement cautioning against services that purport to "cure" people with non-heterosexual sexual orientations as they lack medical justification and represent a serious threat to the health and well-being of affected people, and noted that the global scientific and professional consensus is that homosexuality is a normal and natural variation of human sexuality and cannot be regarded as a pathological condition. The Pan American Health Organization further called on governments, academic institutions, professional associations and the media to expose these practices and to promote respect for diversity. The World Health Organization affiliate further noted that gay minors have sometimes been forced to attend these "therapies" involuntarily, being deprived of their liberty and sometimes kept in isolation for several months, and that these findings were reported by several United Nations bodies. Additionally, the Pan American Health Organization recommended that such malpractices be denounced and subject to sanctions and penalties under national legislation, as they constitute a violation of the ethical principles of health care and violate human rights that are protected by international and regional agreements.
