Warfarin should not be given to people with heparin-induced thrombocytopenia until platelet count has improved or normalised. [39] Warfarin is usually best avoided in people with protein C or protein S deficiency, as these thrombophilic conditions increase the risk of skin necrosis, which is a rare but serious side effect associated with ...
There are three common naming conventions for specifying one of the two enantiomers (the absolute configuration) of a given chiral molecule: the R/S system is based on the geometry of the molecule; the (+)- and (−)- system (also written using the obsolete equivalents d- and l-) is based on its optical rotation properties; and the D/L system is based on the molecule's relationship to ...
Diane Arbus photograph, Identical Twins, Roselle, New Jersey, 1967. Identical Twins, Roselle, New Jersey, 1967 is a noted photograph by photographer Diane Arbus from the United States. Since its debut Identical twins, Roselle, N. J., has become the image most closely associated with her large body of work. The photograph was chosen as the cover ...
Identical twins of the ‘Ask Reddit’ community recently shared what are the main differences between them and their sibling, showing that the dissimilarities can range from a unique mole to one ...
If molecules have a greater affinity for the opposite enantiomer than for the same enantiomer, the substance forms a single crystalline phase in which the two enantiomers are present in an ordered 1:1 ratio in the elementary cell. Adding a small amount of one enantiomer to the racemic compound decreases the melting point.
The study was subsequently the subject of Identical Strangers, a 2007 memoir by separated identical twins Elyse Schein and Paula Bernstein [11] (who appear in the film), as well as the 2017 documentary The Twinning Reaction [12] and a 2018 episode of the American TV news program 20/20 titled "Secret Siblings".

This term has become very popular and commonly used in practice. But the appropriate expression is "enantioselective chromatography". [34] Chiral chromatography has advanced to turn into the most preferred technique for the determination of enantiomeric purity as well as separation of pure enantiomers both on analytical and preparative scale.
