Extracellular Vesicles Derived Ectonucleoside Triphosphate Diphosphohydrolase 3 Alleviates Mitochondrial Dysfunction of Osteoarthritis Chondrocytes via Ectonucleotide Pyrophosphatase/Phosphodiesterase 1-Induced Suppression of the AKT/Notch2 Pathway.

Osteoarthritis (OA) is the most common joint disease that usually starts from joint cartilage injury. Notch2, a versatile signaling in human development and diseases, was recently uncovered to be an important regulator in chondrocyte damage. However, in OA chondrocytes, how Notch2 activation is dysregulated is largely unknown.

Complex Metal Oxides as Emerging Inorganic Hole-Transporting Materials for Perovskite Solar Cells.

Iodide/triiodide redox shuttle-based additives for high-performance perovskite solar cells by simultaneously passivating the cation and anion defects.

Halide perovskite solar cells (PSCs) have received remarkably increasing interests due to their facile fabrication procedures, use of cost-effective raw materials, and high power conversion efficiencies (PCEs) during the past 10 years. Nevertheless, the state-of-the-art organic-inorganic PSCs suffer from high defect concentration and inferior humid/thermal stability, significantly restricting the widespread applications of PSCs. More specifically, point defects including metallic lead (Pb) and halide iodine (I) are easily generated in Pb/I-based PSCs during fabrication processes and operational conditions due to the inferior interaction between the anions and cations in halide perovskites and promote detrimental carrier recombination and ion migration, leading to inferior PCEs and durability of the PSCs.

Overexpression of gastrin and c-met protein involved in human gastric carcinomas and intestinal metaplasia.

Many studies have investigated the expression of c-met and c-erbB2 protein in human gastric adenocarcinomas, but the expression of gastrin protein in human gastric cancer and the relationship between gastrin and c-met are unknown. We have constructed a tissue microarray containing 408 formalin-fixed and paraffin-embedded human tissue blocks, including tissues containing intestinal metaplasia (IM, n=72) and primary tumors (n=232), as well as normal gastric mucosa (n=104) from patients with gastric cancer. Immunohistochemistry (IHC) was used for detecting gastrin, c-met and c-erbB2 proteins.
