A Case Report of Acute Renal Failure due to Amlodipine Overdose and Alcohol Consumption

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Amlodipine intoxication is clinically common yet life‐threatening, usually resulting in severe cardiovascular collapse and end‐organ hypoperfusion. Here, we report a case of a 46‐year‐old male with amlodipine (420 mg) and ethanol intoxication who unexpectedly presented without severe hypotension or shock.

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

The Brain‐Gut Axis in Parkinson's Disease Pathology

open access: yesComprehensive Physiology, Volume 16, Issue 2, April 2026.
Exposure to environmental toxins induces gut dysbiosis, increases intestinal epithelial barrier permeability, immune activation, and oxidative stress, promoting α‐syn misfolding and propagation. Brainstem DMV neurons exhibit α‐syn pathology, dysregulating neuronal excitability and vagal control of GI functions.
