Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.

Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbonyl functional group. =O: Simple representatives of these two bond types are the OH in alcohols such as the ethanol in beverages and fuels and the C=O in ketones (as well as many other related carbonyl compounds).

In this sense of the word, antihistamines are subclassified according to the histamine receptor that they act upon. The two largest classes of antihistamines are H-antihistamines and H-antihistamines. Antihistamines that target the histamine H-receptor are used to treat allergic reactions in the nose (e.g., itching, runny nose, and sneezing) as well as for insomnia. They are sometimes also used to treat motion sickness or vertigo caused by problems with the inner ear. Antihistamines that target the histamine H-receptor are used to treat gastric acid conditions (e.g., peptic ulcers and acid reflux). H-antihistamines work by binding to histamine H receptors in mast cells, smooth muscle, and endothelium in the body as well as in the tuberomammillary nucleus in the brain; H-antihistamines bind to histamine H receptors in the upper gastrointestinal tract, primarily in the stomach.
