Herbicide exposure poses a higher risk to reptiles due to their frequent contact with soil. Besides, food restriction is also a common environmental pressure that can seriously affect the survival of reptiles. The adaptive strategies of reptiles in the face of emerging herbicide pollution and food shortage challenges are not yet known.

Copper II oxide nanoparticles (CuO NPs), a kind of widely used nanomaterial, have been detected in food and the environment, which has aroused widespread public concern. Recently, increasing data have suggested that intestinal microecology is closely related to immune homeostasis. However, the intestinal immunotoxicity induced by CuO NPs through intestinal microbiota is still unknown.

The synergistic effects of ultrafine grinding and enzymolysis (cellulase and Laccase hydrolysis) alone or combined with carboxymethylation or acetylation on the hypoglycemic and antioxidant activities of oil palm kernel fibre (OPKEF) were studied for the first time. After these synergistic modifications, the microstructure of OPKEF became more porous, and its soluble fibre and total polyphenols contents, and surface area were all improved (P < 0.05).

Atmospheric ammonia has great environmental implications due to its important role in ecosystem and nitrogen cycle, as well as contribution to formation of secondary particles. China is recognized as a hotspot of NH pollution owing to agricultural and livestock intensification. In the quest to achieve a comprehensive understanding of atmospheric ammonia load and to quantify its environmental impacts in China, relying solely either on existing measurements or on model simulations falls short.

β-Carbolines norharman and harman, belonging to the class of heterocyclic aromatic amines (HAAs), are typical hazardous substances produced during the thermal processing of food. Compared to other HAAs, there have been limited reports on the toxicity of β-carbolines. Nevertheless, the current studies are concerned with the neurotoxic effects of norharman and harman at high doses.

The effects of acetylation, hydroxypropylation, cellulase hydrolysis and crosslinking on adsorption capacities and in vitro hypoglycemic activities of millet bran dietary fibre (MBDF) were studied. The results demonstrated that both acetylation and hydroxypropylation improved water swelling ability of MBDF, and adsorption capacities of cholesterol, cholate and copper ion on MBDF. Acetylation and hydroxypropylation also enhanced α-glucosidase and α-amylase inhibition activities, glucose-binding ability and glucose diffusion retardation index (GDRI) of MBDF.
