Deoxygenative Borylation of Secondary and Tertiary Alcohols [PDF]
Angewandte Chemie - International Edition, 2019 AbstractTwo different approaches for the deoxygenative radical borylation of secondary and tertiary alcohols are presented. These transformations either proceed through a metal‐free silyl‐radical‐mediated pathway or utilize visible‐light photoredox catalysis. Readily available xanthates or methyl oxalates are used as radical precursors.

Takotsubo cardiomyopathy secondary to alcohol withdrawal
Global Cardiology Science and Practice, 2022 Physical, mental, and emotional stressors have been well known to adversely affect cardiac function. A rare complication of such stressors is stress cardiomyopathy, otherwise known as takotsubo cardiomyopathy. First identified in Japan in the 1990s, takotsubo cardiomyopathy classically presents with systolic dysfunction and apical ballooning.
