Glycolysis-related gene signatures and the functional role of P4HA1 in osteosarcoma prognosis.

Osteosarcoma, a primary malignant bone tumor predominantly affecting children and adolescents, is characterized by aerobic glycolysis, which is intricately linked to tumor progression and metastasis, yet its prognostic implications remain underexplored. This study aimed to develop a prognostic model utilizing glycolysis-related genes and to elucidate the functional role of P4HA1, a key gene within this model, in osteosarcoma prognosis and immune cell infiltration. We collected clinical and transcriptomic data from osteosarcoma patients in the UCSC Xena and GEO databases.

More sensitive microbial responses to the interactive effects of warming and altered precipitation in subsoil than topsoil of an alpine grassland ecosystem.

Subsoil is a large organic carbon reservoir, storing more than half of the total soil organic carbon (SOC) globally. Conventionally, subsoil is assumed to not be susceptible to climate change, but recent studies document that climate change could significantly alter subsoil carbon cycling. However, little is known about subsoil microbial responses to the interactive effects of climate warming and altered precipitation.

Applying Electrospun Gelatin/Poly(lactic acid-co-glycolic acid) Bilayered Nanofibers to Fabrication of Meniscal Tissue Engineering Scaffold.

The menisci are fibrocartilaginous tissues composed primarily of an interlacing network of collagen fibers with nanoscale diameter. Electrospinning is a suitable process of producing nanoscale fibers that mimic collagen fibers. In this study, a bilayered scaffold (group B), which consists of a gelatin nanofiber mesh and a PLGA nanofiber mesh, has been fabricated through an electrospinning method.
