Background: Patients with ulcerative colitis (UC) exhibit abnormal amino acid (AA) metabolism. Taste receptors play a crucial role in the detection of intestinal AAs. Nevertheless, it remains unclear whether UC patients exhibit abnormal expression of these receptors in the colon.

Currently, internationally recognized general sacrifice methods for commonly used laboratory animals have been established, but there remains significant controversy over the sacrifice methods for turtles. To explore the effectiveness of various immobilization methods and their impact on stress-related indicators in turtles, this study used red-eared sliders (Trachemys scripta elegans) as subjects.

The aim of this study was to comprehensively assess the relationship between metabolic abnormalities, liver enzymes, and gallstone risk through a cross-sectional study and Mendelian randomization analysis.
Methods: Firstly, a cross-sectional study was conducted involving 555,31 subjects who underwent physical examinations at the Second Affiliated Hospital of Xi'an Jiaotong University between January 2021 and December 2021.
The content and composition of intramuscular fat (IMF) affect the cooked meat palatability such as tenderness and juiciness. Thus, elucidation of lipid deposition and its composition in goat IMF is necessary. Here, Jianzhou big-ear goats with higher IMF content is associated with lower mRNA level of LKB1 gene, compared with those of Chuannan black goats.

Although the central requirement of Smad4 as a common mediator is emphasized in regulating TGFβ signaling, it is not obligatory for all responses. The role of Smad2/3 independently of Smad4 remains understudied.

Conservation has improved by increasing the number of protected species. However, a notable shortcoming undermines the effectiveness of protection for as many as 87 species, as the regulation applies only to wild and not to captive individuals (Figure 1 and Table S1).

This study aimed to explore the effects of 3 concentrations of dietary AFB (0, 50, and 500 μg/kg) on hepatic injury and metabolism in Saanen goats via histological examination, Western blot analysis, as well as integrated multi-omics techniques. Eighteen Saanen goats were assigned to 1 of 3 treatments and the AFB challenge lasted for 14 d.

Artificial breeding is a recovery strategy, yet it risks introducing antibiotic resistance genes (ARGs) to wild populations and ecosystems. This study employed metagenomic techniques to compare the distribution characteristics of ARGs in the guts of wild and artificially bred green turtles (Chelonia mydas).

However, its effects on turtles are largely unexplored. Our study aimed to investigate the toxic effects of Cr(VI) on the Reeves' turtles () primary hepatocytes.

However, generalizing this association is controversial. Research on sexually dimorphic hearing sensitivity contributes to an understanding of auditory sense functions, adaptations, and evolution among species.

Yet the impact and response mechanism of compound fertilization rates on carbon sinks in agroforestry systems remain ambiguous. This study aims to elucidate the impact of different compound fertilizer rates on soil greenhouse gas (GHG) emissions, vegetation and soil organic carbon (SOC) sinks, and to illustrate the differences in agroforestry systems' carbon sinks through a one-year positioning test across 12 plots, applying different compound fertilizer application rates (0 (CK), 400 (A1), 800 (A2), and 1600 (A3) kg ha).

The gut microbiota plays a crucial role in the host's response and adaptation to new environments. In this study, we investigated the changes in microbial communities in Red-eared slider () under acidic conditions to reveal the ecological impacts of acidification on freshwater turtles.

However, there is a lack of experimental evidence to show that animals actively choose objects that match these body parameters. To explore how the Hainan four-eyed turtle, , masquerades using suitable stones, we used indoor video surveillance technology to study the preferences of juvenile for stones of different sizes, shapes, and colors.
