Sintering Ag Nanoclusters on TiO Nanoparticles as an Efficient Catalyst for Nitroarene Reduction.

Polydispersed Ag species-modified TiO samples with abundant oxygen vacancies were successfully prepared through the calcination of atomically precise Ag nanocluster-loaded TiO at an optimal temperature under a nitrogen atmosphere. The ligands of the Ag nanoclusters are removed by extracting lattice oxygen from TiO during the calcination, leading to the formation of CO, SO, and HO vapor. This process simultaneously induces Ag species sintering on the surface of TiO.

Association between pre-stroke frailty and post-discharge destination in acute stroke among Chinese older adults.

Aims: To investigate the association between pre-stroke frailty and discharge destination in hospitalized older adults in China.

Methods: We conducted this prospective cohort study in a tertiary care hospital in China. We enrolled patients aged 60 years and older admitted to the hospital for acute stroke from January 2022 to May 2022.

Corrigendum: Bibliometric analysis of research on digestive system tumors and depression.

The molecular mechanism of gemcitabine in inhibiting the HIF-1α/VEGFB/FGF2/FGFR1 signaling pathway for ovarian cancer treatment.

Ovarian cancer is a common malignant tumor in women, exhibiting a certain sensitivity to chemotherapy drugs like gemcitabine (GEM). This study, through the analysis of ovarian cancer single-cell RNA sequencing (scRNA-seq) data and transcriptome data post-GEM treatment, identifies the pivotal role of hypoxia-inducible factor 1 alpha (HIF-1α) in regulating the treatment process. The results reveal that HIF-1α modulates the expression of VEGF-B, thereby inhibiting the fibroblast growth factor 2 (FGF2)/FGFR1 signaling pathway and impacting tumor formation.
