Identification and Quantification of Volatile Organic Compounds and Bioaerosols in the Conservation Processes of Guanche Mummies

open access: yesArchaeometry, EarlyView.
ABSTRACT The Guanche mummies, ancient inhabitants of the Canary Islands, represent a significant part of the historical heritage preserved at the Museum of Nature and Archaeology (MUNA) in Tenerife, Spain. These mummies, subjected to artificial conservation practices, are of great interest to conservators seeking to understand their mummification ...

Photoredox/Ti dual-catalyzed dehydroxylative ring-opening Giese reaction of cyclobutanone oximes

open access: yesGreen Synthesis and Catalysis
A dehydroxylative ring-opening Giese reaction of cyclobutanone oximes enabled by photoredox/Ti dual catalysis has been reported in this work. This protocol avoids the prefunctionalization of oximes and the use of stoichiometric triarylphosphine reagents.

Functional Characterization of the Cat and Dog Wild‐Type and Mutant MDR1 Carrier Proteins and Frequency of the MDR1 Gene Mutation in 800 Cats From Germany

open access: yesJournal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT The ATP‐binding cassette transporter MDR1 P‐glycoprotein (syn. ABCB1) is an efflux carrier at the cell membrane that regulates drug absorption, distribution, and elimination. At the blood–brain barrier, MDR1 restricts brain entry of potentially neurotoxic drugs, such as ivermectin. In dogs and cats, MDR1 (syn.

Dual Co/Photoredox‐Catalyzed Regio‐ and Stereoselective Synthesis of Highly Functional 1,3‐Dienes

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
A generic regio‐ and stereoselective protocol for the synthesis of functionalized 1,3‐dienes is presented that is facilitated via a dual Co/photoredox catalyst system while using modular 1,3‐enynes and unsaturated carbonyl derivatives as substrates. Key to the success of this transformation is the generation of a Co(III)H species that adds to the 1,3 ...
