Naturally occurring long-chain β-hydroxyketones

open access: yesJournal of Lipid Research, 1971
A fraction comprising about 0.7% of the extractable surface lipids of cabbage (Brassica oleracea) leaves was isolated and identified as a mixture of isomeric βhydroxyketones consisting mainly of 14-keto-16-hydroxynonacosane and 15-keto-13 ...

Secondary fatty alcohols of Mycobacterium xenopi [PDF]

open access: yesJournal of General Microbiology, 1992
Secondary alcohols of Mycobacterium xenopi were studied by gas chromatography and gas chromatography-mass spectrometry. Mycobacterial cells were hydrolysed and the liberated alcohols separated by extraction and analysed both underivatized and as trimethylsilyl, methyl ether- and pentafluorobenzoyl derivatives.

Takotsubo cardiomyopathy secondary to alcohol withdrawal

open access: yesGlobal 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.
