Could NAPQI Contribute to Paracetamol Analgesia? Redox Modulation of Kv7 Ion Channels

Pharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT Paracetamol (acetaminophen, APAP) is one of the most widely used analgesic and antipyretic drugs worldwide, yet its mechanism of action remains incompletely understood. While several pathways have been proposed, including cyclooxygenase inhibition and endocannabinoid modulation via AM404, none fully account for its pharmacological profile. The

First‐Time Demonstration of a Two‐Step Mechanism for Azo Dye Removal by Bacillus proteolyticus Using Molecular Docking and FT‐IR

Water Environment Research, Volume 98, Issue 8, August 2026.
Bacillus proteolyticus OA7, isolated from textile wastewater, efficiently removed Acid Red 88 (69.74%) and Acid Blue 193 (41.01%) through substrate‐dependent mechanisms. Acid Red 88 removal involved both biosorption and biodegradation, whereas Acid Blue 193 was mainly biosorbed. FT‐IR revealed functional group changes associated with EPS, proteins, and

A case of canine urothelial carcinoma of the urinary bladder with skull and skeletal metastases

Australian Veterinary Journal, Volume 104, Issue 8, Page 509-514, August 2026.
Canine urinary bladder neoplasia is uncommon, representing less than 1% of canine neoplasms. Amongst cases of urinary bladder neoplasia in dogs, primary urothelial carcinoma is the most frequent. Urothelial carcinomas are malignant invasive tumours which tend to be slow growing and metastasise late.

Natural variation in OsMYB305 downregulating cytokinin‐mediated inhibition of leaf senescence contributes to regional adaptation in rice

New Phytologist, Volume 251, Issue 4, Page 1873-1888, August 2026.
Proposed regulatory model of OsMYB305 in leaf senescence. Summary Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown.

Deep Eutectic Solvent‐Type Mixture as a Green Catalyst in the Solvent‐Free Cycloaddition of CO2 and Epoxides

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
A green, metal‐free catalytic system based on a deep eutectic solvent‐type mixture of tetrabutylammonium iodide and levulinic acid enables the solvent‐free cycloaddition of carbon dioxide (CO2) to epoxides. Cooperative acid–nucleophile activation affords cyclic carbonates in up to 95% yield at atmospheric pressure using only 1.4 mol% of catalyst.

NOVOS HÍBRIDOS BASEADOS EM OXIHIDRÓXIDO DE FERRO(III) E NANOPARTÍCULAS DE OURO (AuNPs/FeOOH) COMO CATALISADORES PARA A REDUÇÃO DE POLUENTES ORGÂNICOS AMBIENTAIS

Química Nova
A new δ-FeOOH supported nano-Au catalyst was prepared by a facile method using HAuCl4 as the gold source and NaBH4 as the reducing agent. The samples (denoted as AuNPs/FeOOH) were characterized by means of X-ray diffraction (XRD), UV-vis and infrared ...
