Atazanavir atazanavir is a structural analog of the transition state during which the bond between a phenylalanine and proline is broken. Humans do not have any enzymes that break bonds between phenylalanine and proline, so this drug will not target human enzymes. Atazanavir is available as a 150 mg capsule, 200 mg capsule, 300 mg capsule, and 50 mg oral powder packet. The 300 mg capsule should reduce pill burden, as one 300 mg capsule may replace two 150 mg capsules. Atazanavir Atazanavir, sold under the trade name Reyataz among others, is an antiretroviral medication used to treat and prevent HIV/AIDS.
Knaster's condition Knaster's condition In mathematics, a partially ordered set "P" is said to have Knaster's condition upwards (sometimes property (K)) if any uncountable subset "A" of "P" has an upwards-linked uncountable subset. An analogous definition applies to Knaster's condition downwards. The property is named after Polish mathematician Bronisław Knaster. Knaster's condition implies the countable chain condition (ccc), and it is sometimes used in conjunction with a weaker form of Martin's axiom, where the ccc requirement is replaced with Knaster's condition. Not unlike ccc, Knaster's condition is also sometimes used as a property of a topological space, in which case it means
