It is well-established that chronic hyperglycemia progressively destroys the heart structure, weakening function and leading to diabetic cardiomyopathy (DCM). Extracellular vesicles derived from adipose-derived stem cell (ADSC-EVs) have been reported to have anti-inflammatory and immune-modulating effects, but their role in DCM is still poorly understood. Therefore, this study investigated the impact of ADSC-EVs on DCM and potential mechanisms.

The phylogenetic relationships and species diversity for Sylvirana and allied genera remain unresolved and controversial due to insufficient data and incomplete taxon sampling. Using a combined dataset of mitochondrial genes (16S and COI) and 101 nuclear genes obtained through the amplicon sequence capture approach, we generated the most comprehensive phylogenetic analysis for the genus Sylvirana to date, inferring diversity, phylogenetic relationships, and historical biogeography with unprecedented levels of taxon and geographic sampling.

Identifying and protecting hotspots of endemism and species richness is crucial for mitigating the global biodiversity crisis. However, our understanding of spatial diversity patterns is far from complete, which severely limits our ability to conserve biodiversity hotspots. Here, we report a comprehensive analysis of amphibian species diversity in China, one of the most species-rich countries on Earth.

However, the relationship between SHR and coronary artery disease (CAD) severity has hitherto not been reported. This study sought to clarify the relationship between the SHR and CAD severity of individuals with different glucose metabolic statuses.

However, several research studies have determined that the level of amphibian diversity in the country has been significantly underestimated. The megophryid genus Smith, 1925 is currently known to include 89 species that are primarily distributed throughout southern China and Southeast Asia; however, only seven species have been found in Thailand.

Most of the species distribution has been recorded in China; however, a few incidences of identification have occurred in the eastern part of Indochina. To date, only one species () of has been recorded from Chanthaburi and Trat Provinces in south-eastern Thailand.

The Himalayan region is a relatively small area but with exceptional diversity and endemism. One common hypothesis to explain the rich montane diversity is uplift-driven diversification-that orogeny creates conditions favoring rapid speciation of resident lineages.
