Rising, falling, stalling: complex biodiversity trajectories in English rivers

Ecography, EarlyView.
Freshwater ecosystems face intense anthropogenic pressures. Yet in parts of Europe, including the UK, studies have documented widespread increases in macroinvertebrate diversity following investments to improve water quality. More recent analyses, however, suggest that these gains have slowed, plateaued, or even reversed. Despite increasing recognition

Synthesis of S‐Linked Glycoconjugates of Monosaccharides and Levoglucosenone Derivatives Through Photoinduced Thiol–Ene Reaction Mediated by 4CzIPN and Its Water Soluble Analog

European Journal of Organic Chemistry, EarlyView.
Visible‐light thiol–ene reaction mediated by 4CzIPN enables access to hydrolytically stable S‐linked glycoconjugates from levoglucosenone‐derived thiols (Y = 91% to quant. d.r. = up to >95:5) and conventional thio‐sugars (Y = 80% to quant. d.r. = up to >95:5).

Effects of flow‐controlled expiration on oxygenation and early recovery in horses undergoing general anaesthesia

Equine Veterinary Journal, EarlyView.
Abstract Background FLow‐controlled EXpiration (FLEX) has been shown to significantly enhance oxygenation in horses under clinical and experimental conditions. Objectives To compare pulmonary gas exchange during early recovery following general anaesthesia in horses ventilated with FLEX compared with conventional intermittent positive pressure ...

Warmed intravenous fluid administration attenuated a reduction in body temperature in anaesthetised horses

Equine Veterinary Journal, EarlyView.
Abstract Background Peri‐anaesthetic hypothermia is a well‐documented complication of general anaesthesia and is associated with prolonged recovery, impaired wound healing, and delayed coagulation. Fluid warmers can be used to mitigate heat loss, but there is little evidence supporting their effectiveness in equine anaesthesia.

Food Contamination and Safety in Nigeria: A Systematic Synthesis of Heavy Metals, Microbial Pathogens, and Health Risk Metrics

Food Safety and Health, EarlyView.
This is an infographic driver of food contaminants and health effects. ABSTRACT Food safety remains a critical challenge in Nigeria due to rapid urbanization and weak regulatory enforcement. This systematic review synthesizes empirical evidence from 2015 to 2025 to characterize food contaminant profiles and associated human health risks in Nigeria ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of
