Medical history

The medical history or (medical) case history (also called anamnesis, especially historically) (often abbreviated hx or Hx) of a patient is information gained by a physician by asking specific questions, either of the patient or of other people who know the person and can give suitable information (in this case, it is sometimes called heteroanamnesis), with the aim of obtaining information useful in formulating a diagnosis and providing medical care to the patient. The medically relevant complaints reported by the patient or others familiar with the patient are referred to as symptoms, in contrast with clinical signs, which are ascertained by direct examination on the part of medical personnel. Most health encounters will result in some form of history being taken. Medical histories vary in their depth and focus. For example, an ambulance paramedic would typically limit their history to important details, such as name, history of presenting complaint, allergies, etc. In contrast, a psychiatric history is frequently lengthy and in depth, as many details about the patient's life are relevant to formulating a management plan for a psychiatric illness.

Oxybenzone

Oxybenzone or benzophenone-3 (trade names Milestab 9, Eusolex 4360, Escalol 567, KAHSCREEN BZ-3) is an organic compound. It is a white solid that is readily soluble in most organic solvents. Oxybenzone belongs to the class of aromatic ketones known as benzophenones. It is a component of many sunscreen lotions.

Structure and electronic structure

Being a conjugated molecule, oxybenzone absorbs at lower energies than many aromatic molecules. As in related compounds, the hydroxyl group is hydrogen bonded to the ketone. This interaction contributes to oxybenzone's light-absorption properties. At low temperatures, however, it is possible to observe both the phosphorescence and the triplet-triplet absorption spectrum. At 175 K the triplet lifetime is 24 ns. The short lifetime has been attributed to a fast intramolecular hydrogen transfer between the oxygen of the C=O and the OH.

Production

Oxybenzone is produced by Friedel-Crafts reaction of benzoyl chloride with 3-methoxyphenol(3-hydroxyanisole).

HORSE

H.O.R.S.E. is a form of poker commonly played at the high-stakes tables of casinos. It consists of rounds of play cycling among:

Rules

H.O.R.S.E. is a limit game, including hold 'em. However, in some tournament situations (such as the 2006 World Series of Poker event), the final table is no-limit hold 'em.

C.H.O.R.S.E adds Chowaha or Crazy Pineapple to the mix. This is convenient at such team events as BARGE, when it helps to have as many flop games as stud games. C.H.O.R.S.E.L adds lowball.

T.H.O.R.S.E.H.A. is another 8-Game Mix which includes more games than most other mixed poker games.PokerStars started offering this game in 2008. It consists of limit 2-7 Triple Draw, limit Texas hold 'em, limit Omaha Hi-Lo, limit Razz, limit Seven-card Stud, limit Seven card Stud Hi-Lo, no limit Texas hold 'em and pot limit Omaha.

10-Game, the latest variation on the mixed poker games, overtook T.H.O.R.S.E.H.A. in the extent of its game inclusion. Launched by Full Tilt Poker in November 2010, 10-Game includes Limit Hold 'em, Limit Stud Hi/Lo, Pot Limit Omaha Hi, Limit 2-7 Triple Draw, Limit Razz, No Limit Hold ‘em, Limit Omaha Hi/Lo, Limit Stud Hi, No Limit 2-7 Single Draw and Limit Badugi. Full Tilt Poker also offers the 9-Game, which includes all poker variants from the 10-Game with the exception of Badugi.
