Structure‐Guided Surface Engineering of an Artificial Metallolyase for Highly Enantioselective Michael Addition

open access: yesChemCatChem, Volume 18, Issue 11, 15 June 2026.
X‐ray visualization of copper‐binding modes revealed nonspecific surface metal sites that compromise stereoselectivity. Structure‐guided mutations suppressed background reactivity and enabled precise enantioselective control in the Michael addition, delivering up to 99% ee.

Selective Rh(II)‐Catalyzed Intermolecular Oxyamidation and Acid‐Promoted Nucleophilic Cyclization Cascade of Enamides

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
A structurally diverse series of 1‐amino‐izidine scaffolds was accessed through a cascade process combining rhodium‐catalyzed nitrene‐transfer oxyamidation with subsequent nucleophilic cyclization under acidic conditions, proceeding via an in situ generated iminium intermediate.

Mu Opioid Receptor mRNA and Protein Localization Across the Rat and Mouse Habenula

open access: yesJournal of Comparative Neurology, Volume 534, Issue 6, June 2026.
Mu opioid receptor (MOR) mRNA was detected with RNAscope in situ hybridization for Oprm1 and protein was detected with immunocytochemistry to map the distributions across the anterior‐posterior extent of the rat and mouse habenula. Expression distribution was also characterized in a transgenic reporter mouse line (Oprm1‐Venus/Venus) as an additional ...

FDA Approval of Donanemab‐azbt: A New Dawn in Alzheimer's Disease Treatment

open access: yesHealth Science Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Background Alzheimer's disease (AD) is a neurodegenerative condition marked by the accumulation of beta‐amyloid plaques and neurofibrillary tangles, leading to neuronal death and cognitive decline. Acetylcholinesterase inhibitors (AChEIs) such as donepezil, galantamine, and rivastigmine are commonly used to enhance cognitive function by ...

Ivermectin Toxicity in Humans and Animals: Clinical Spectrum, Mechanisms, and Management

open access: yesJournal of Applied Toxicology, Volume 46, Issue 6, Page 1856-1870, June 2026.
ABSTRACT Ivermectin is a widely used macrocyclic lactone with established efficacy against a broad range of parasitic infections in humans and animals and a long‐standing reputation for clinical safety. However, increasing evidence indicates that ivermectin can produce clinically relevant toxicity under specific conditions, particularly involving the ...

Engineered Pericyte‐Targeted Extracellular Vesicles Protect Against Hypoperfusion‐Induced Cognitive Impairment and Vascular Demyelination

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
Schematic illustration on a therapeutic strategy wherein engineered extracellular vesicles (EVs) are delivered intranasally and specifically target pericytes. In a model of chronic cerebral hypoperfusion (BCAS), this targeted approach preserves cerebral blood flow, reinforces blood‐brain barrier (BBB) integrity, stabilizes the neurovascular unit (NVU),

Pain‐Related Smoking Expectancies Across Tobacco Product Use Patterns, Including Heated Tobacco Products: Psychometric Validation of the Japanese Pain and Smoking Inventory

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
The newly validated Japanese Pain and Smoking Inventory (PSI) demonstrates that higher pain‐related smoking expectancies predict greater pain intensity and disability. Among tobacco use patterns, dual users exhibit the highest expectancies, while switchers show the lowest scores.

Adolescent Exposure to Nicotine and Ethanol Attenuates Adult Nicotine Reward Sensitivity in Rats

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
We investigated how chronic exposure to nicotine, ethanol, or their combination during adolescence influences adult conditioned place preference (CPP) for nicotine. No significant CPP was observed in any of the drug‐exposed groups, suggesting adolescent exposure to addictive substances does not uniformly increase vulnerability to nicotine reward ...

Combined Inhibition of TRPM4/NMDA Receptor Complex and Extrasynaptic NMDA Receptors Is Candidate Therapeutic Target for Suppression of Epileptic Seizures and Improvement of Cognitive Impairments

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Cognitive impairments are important therapeutic targets in epilepsy medication; however, effective pharmacological treatments for epilepsy patients with comorbid cognitive impairment have not been established. Effects of chronic administration of MK‐801 (noncompetitive NMDA receptor inhibitor), memantine (low‐affinity extrasynaptic‐NMDA ...
