Stereodivergent, Kinetically Controlled Isomerization of Terminal Alkenes via Nickel Catalysis

Angewandte Chemie, Volume 136, Issue 21, May 21, 2024.
The nickel‐catalyzed kinetic alkene mono‐transposition generates E‐ or Z‐olefins depending on the steric properties and denticity of the ligand employed. Mechanistic studies reveal that the aryl iodide additive acts as a redox buffer for nickel in the Z‐selective reaction, generating the most‐selective NiII–H that outcompetes a less Z‐selective NiI–H ...

Acute Respiratory Distress following Intravenous Injection of an Oil‐Steroid Solution

Canadian Respiratory Journal, Volume 18, Issue 4, Page e59-e61, 2011., 2011
A case of acute respiratory distress and hypoxemia following accidental intravenous injection of an oil‐steroid solution in a body builder is presented. Chest roentography at the time of presentation showed diffuse bilateral opacities, and computed tomography revealed predominantly peripheral ground‐glass opacifications.

Nandrolone decanoate–induced hypogonadism in male rats: Dose‐ and time‐dependent effects on pituitary and testicular hormonal functions

Physiological Reports, Volume 12, Issue 19, October 2024.
Impacts of nandrolone decanoate (ND) were studied on pituitary‐testis axis in male rats, and compared with testosterone enanthate (TE). Results show ND‐ or TE‐induced hypogonadism coincided with inhibition of T biosynthesis, and suggest disruption of T negative feedback on pituitary. The testes showed histopathological defects in both ND and TE treated
