Constructing Cu defect band within TiO and supporting NiO nanoparticles for efficient CO photoreduction.

Effectively harnessing solar energy for the conversion of CO into valuable chemical energy presents a viable solution to address energy scarcity and climate change concerns. Nonetheless, the limited light absorption and sluggish charge kinetics significantly hinder the photoreduction of CO. In this study, we employed a facile sol-gel method combined with wetness impregnation to synthesize Cu-doped TiO coated with NiO nanoparticles.

Fabrication of a ternary NiS/ZnInS/g-CN photocatalyst with dual charge transfer channels towards efficient H evolution.

As a renewable green energy, hydrogen has received widespread attention due to its huge potential in solving energy shortages and environment pollution. In this paper, a one-step solvothermal method was applied to grow ultra-thin g-CN (UCN) nanosheets and NiS nanoparticles on the surface of ZnInS (ZIS). A ternary NiS/ZnInS/ultra-thin-g-CN composite material with dual high-speed charge transfer channels was constructed for the advancement of the photocatalytic H generation.

Z-Scheme MoS/g-CN heterojunction for efficient visible light photocatalytic CO reduction.

Z-Scheme MoS2/g-C3N4 heterojunction photocatalysts were fabricated using a hydrothermal deposition procedure together with a calcination route, and then applied for CO2 photoreduction. Experimental results indicated that the 10% MoS2/g-C3N4 heterojunction displayed the best photocatalytic performance. Furthermore, the maximum CO yields of 58.

[Vascular endothelial growth factor gene polymorphisms and the risk of endometriosis: a systematic review].

Objective: To analyze the potential association between the single nucleotide polymorphisms (SNP) of the vascular endothelial growth factor (VEGF) gene with the risk of endometriosis by meta-analysis.

Methods: Published case-control studies about the influence of VEGF polymorphisms on endometriosis were searched and screened in Medline, the Cochrane library, China National Knowledge Internet (CNKI), Chinese Biological Medicine Disk (CBM), data base of Wanfang and Foreign Medical Journal Full-Text Service (FMJS). RevMan 5.

[Ca(2+) is an important mediator of nanosecond steep pulse-induced apoptosis in human ovarian cancer SKOV3 cells].

Objective: To explore the role of Ca(2+) in nanosecond steep pulse (NSP)-induced apoptosis of human ovarian carcinoma cell line SKOV3 in vitro.

Methods: The early apoptotic rate of SKOV3 cells treated with NSP was detected by Annexin V/PI double staining and flow cytometry. MTT assay was used to detect the viability of the cells pretreated with BAPTA-AM (0, 25, 50 and 100 µmol/L) chelation for 1 h to increase the intracellular free Ca(2+) prior to NSP exposure, and the cell morphological changes and caspase 12 expression were detected using Hoechst 33342 staining and Western blotting, respectively.

Response of early stage bulky cervical squamous carcinoma to preoperative adjuvant chemotherapy.

Objective: To investigate the potential role of preoperative adjuvant chemotherapy on early stage cervical squamous carcinoma with bulky tumor.

Methods: One hundred and forty-five patients with cervical squamous cancer stages Ib-IIa were investigated, among which 17 patients with bulky tumors (> or = 4 cm) were managed by cisplatin-based chemotherapy for 1-2 courses followed by radical hysterectomy and pelvic lymphadenectomy (BC group). The change of tumor size, pelvic lymph nodes metastasis, cervical wall invasion, the involvement of surgical specimen margin, and the blood loss during operation were assessed after operation and compared with those in 51 patients with bulky tumors (BN group) and 77 patients with small local tumors (S group) who underwent surgery directly.
