Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

open access: yesThe Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Metabolic Adaptations to Weight Loss in Obese Senior Dogs: Effects on Energy Expenditure, Protein Turnover, and Voluntary Physical Activity

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Implications of obesity and weight loss (WL) for energy and protein metabolism are not fully understood, particularly in senior dogs. This study evaluated changes in body composition, energy expenditure (EE), protein turnover (PT), and voluntary physical activity (VPA) in senior dogs in maintenance and after 10% and 20% WL.

Phosphatidylcholine acyl turnover facilitates thylakoid lipid remodeling and promotes plant survival under heat stress

open access: yesNew Phytologist, EarlyView.
Coordinated galactolipid–TAG conversion during heat stress–induced thylakoid lipid remodeling. Summary Heat stress destabilizes chloroplast membranes, requiring rapid lipid remodeling to maintain photosynthetic function. Although thylakoid lipid remodeling and triacylglycerol (TAG) accumulation are established heat responses, the role of ...

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...

Lipidomics of orchid seeds: from development to storage

open access: yesPlant Biology, EarlyView.
The study tracked lipid changes from pollination to storage in two orchid species. Although both were desiccation‐tolerant and storable, differences in saturated and unsaturated fatty acid proportions during development led to different moisture contents and germination capacities.
