Article Abstract
In the present study, assay of the serum leptin concentration of the Japanese black bear (Ursus thibetanus japonicus) was attempted using a canine-leptin-specific sandwich enzyme-linked immunosorbent assay (ELISA). The dose-response curve of the bear serum was linear and parallel to the canine leptin standard curve. In mated and unmated bears, the serum leptin concentration was stable at low levels from May to August or September, gradually increased from September or October, and then remarkably increased in late November. We conclude that this method may be useful for measuring bear serum leptin concentration and that the serum leptin concentration changes annually with a peak in late November.

Obesogenic feeding can affect systemic metabolism and impact bone health and microarchitecture, but the findings of published studies often appear contradictory. This study aimed to compare the effects of a medium-fat/high-sugar (MF/HS) and a high-fat/high-fructose (HF/Fr) diet on the femora of weanling male Wistar rats, examining bone mineral content and density (BMC, BMD), cortical and cancellous bone microarchitecture and the cell populations within bone. Furthermore, we explored the correlations between circulating bone-targeting factors (in particular leptin, adiponectin and insulin) and bone parameters.
Bangia fusco-purpurea polysaccharide (UBFP) with ultra-high pressure assisted extraction has good in vitro hypolipidemic activity. To be explored as a natural hypolipidemic agent, the alleviation effect of UBFP on in vivo dyslipidemia in high-fat diet (HFD) induced mice was further investigated. Compared with native polysaccharide (BFP), UBFP was better to reduce weight gain, fat accumulation, serum and hepatic lipid abnormalities for HFD induced mice.
Obesity is a worldwide health issue. Effective and safe methods for obesity management are highly desirable. In the current study, hyperbaric oxygen (HBO) treatment was investigated as a potential treatment against obesity-associated hyperphagia and hyperenergy intake.

Cadmium (Cd) is among the top seven most hazardous environmental contaminants. Minimal risk levels for daily exposure have been established, such as no observable adverse effect level (NOAEL) and lowest observable adverse effect level (LOAEL). Chronic exposure to Cd, at both NOAEL and LOAEL doses, causes toxicity in diverse tissues.
Aims: This study aimed to explore the correlation between radiomics features of pericoronary adipose tissue (PCAT) and gene expression in patients with coronary artery disease (CAD), with the goal of identifying novel imaging biomarkers for evaluating CAD.
Methods: Between November 2021 and May 2022, data were collected from 60 patients diagnosed with CAD who underwent coronary artery bypass grafting (CABG) and coronary computed tomography angiography (CCTA). Samples of PCAT, three additional adipose tissue types, and peripheral venous blood were analysed.
