The widespread utilization of antibiotic growth promoters (AGPs) boosts the growth rate of food animals and enhances human living standards. Nevertheless, it is accompanied by escalating antibiotic resistance. Consequently, there is an urgent demand to develop novel alternatives to growth promoters.

Tobacco smoke has numerous adverse effects on both human and animal health, including impaired reproductive function. Recent research has explored environmental exposure in dogs, investigating various biological matrices. However, no data are currently available on the presence of cotinine, a nicotine metabolite, in the canine ejaculate.

Peroxynitrite (ONOO) plays an important role in many physiological and pathological processes. Excessive ONOO in cells leads to oxidative stress and inflammation. However, precise monitoring of ONOO levels in specific organelles (e.

Choline is an important molecule in monitoring food safety and infant nutrition. Here, we report Ce nanogels synthesized by atom transfer radical polymerization (ATRP) employing Ce-coordinated acryloyl-lysine polymer brushes (Ce@SiO NGs) as highly efficient cascade nanozymes for colorimetric detection of choline. The synthesized Ce@SiO NGs demonstrated remarkable peroxidase-like activity with a porous exterior, which are essential to entrap choline oxidase (COx) to yield COx@Ce@SiO NGs and construct a cascade reaction system to detect choline.

Social learning, learning from other individuals, has been demonstrated in many animals, including insects, but its detailed neural mechanisms remain virtually unknown. We showed that crickets (Gryllus bimaculatus) exhibit aversive social learning with a dead conspecific. When a learner cricket was trained to observe a dead cricket on a drinking apparatus, the learner avoided the odor of that apparatus thereafter.
