[Research progress in the regulation of functional homeostasis of adipose tissue by exosomal miRNA].

Adipose tissue holds a pivotal position in maintaining systemic energy homeostasis. Brown adipose tissue (BAT) expresses uncoupling protein 1 (UCP1), which is specialized in dissipating chemical energy as heat to maintain euthermia, a process called non-shivering thermogenesis. Conversely, white adipocyte (WAT) predominantly serves as the primary reservoir for energy storage, while also exhibiting endocrine activity by secreting various adipokines, thereby modulating systemic metabolism.

[Stable isotope ratio characteristics and origin tracing of ].

A method for geographical discrimination of was explored to provide technical support for the protection of geographical indication products and for tracing the origin of seafood. were collected from three major production areas, including the Yellow Sea, the Bohai Sea, and the East China Sea. The variations of carbon and nitrogen stable isotope values of origins and the correlation of stable isotope ratios in different tissues were analyzed.

Clinical features and management strategy of symptomatic spontaneous isolated celiac artery dissection.

Objectives: The aim of this study was to evaluate the clinical features and management strategy for patients with symptomatic spontaneous isolated celiac artery dissection (SICAD).

Methods: In this retrospective study, consecutive patients with symptomatic SICAD from two institutions were included. The demographics, clinical manifestations, comorbidities, imaging findings and treatment strategy selection were obtained from the medical records.

Simultaneous determination of malachite green, crystal violet, methylene blue and the metabolite residues in aquatic products by ultra-performance liquid chromatography with electrospray ionization tandem mass spectrometry.

This work describes solid-phase extraction-ultra-performance liquid chromatography with electrospray ionization tandem spectrometry for determination of malachite green and metabolite leucomalachite green, crystal violet and metabolite leucocrystal violet, methylene blue and metabolites including azure A, azure B and azure C in aquatic products. Samples were extracted with acetonitrile and ammonium acetate buffer and purified by liquid extraction with dichloromethane, and then on MCAX solid-phase extraction cartridges. Then the extract was evaporated at 45°C by nitrogen blow.
