To investigate the association of single nucleotide polymorphism 260 and 386 (SNP260 and SNP386) gene with male infertility, an electronic search was performed to identify case-control studies evaluating the relationship of SNP260 or SNP386 of deleted in azoospermia-like (DAZL) and male infertility. Review Manager 5 was used to process the meta-analysis and other statistical analysis. A total o...

Merkel Cell Polyomavirus (MCPyV) genomes are clonally integrated in tumor tissues of approximately 85% of all Merkel cell carcinoma (MCC) cases, a highly aggressive tumor of the skin which predominantly afflicts elderly and immunosuppressed patients. All integrated viral genomes recovered from MCC tissue or MCC cell lines harbor signature mutations in the early gene transcript encoding for the ...

The cytotoxicity of 193 and 248 nm excimer laser radiation was compared to that produced by a germicidal lamp (predominantly 254 nm) using Chinese hamster ovary cells (CHO), and a human diploid fibroblast line, AG-1522A. Excimer laser radiation at 248 nm (3.5 X 10(2) w/m2) and germicidal radiation (5.3 X 10(-5) w/m2) caused toxicity in both cell lines, with the AG-1522A cells (D37 = 7-8 J/m2) b...

A detailed investigation of the functionality of inverted organic photovoltaics (OPVs) using bare Ag contacts as the top electrode is presented. The inverted OPVs without a hole-transporting layer (HTL) exhibit a significant gain in hole-carrier selectivity and power-conversion efficiency (PCE) after exposure in ambient conditions. Inverted OPVs comprised of ITO-ZnO-poly(3-hexylthiophene-2,5-di...

Sera from 600 male homosexual patients were tested for hepatitis B antigen (HBs Ag) and its antibody (HBs Ab). Thirty-one men (5-2%) were positive for HBs Ag. Testing for HBs Ab by immuno-osmoelectrophoresis 33 men (5-5%) were positive. However, sera of 85 patients negative for HBs Ab by routine methods were examined for HBs Ab by radioimmune assay. Thirty (35%) sera were found to be positive. ...

This paper focuses on the structural, electronic, and vibrational features of amorphous graphite [R. Thapa et al, Phys. Rev. Lett., 2022, 128, 236402]. The structural order in is discussed compared with carbon. electronic density states localization these phases were analyzed. Spatial projection charge densities π bands showed a high concentration participating atoms connecting hexagons. A was ...

In this paper, the microstructure of Ag nano paste joint was investigated in pressure-less sintering conditions, and influence on joint’s reliability studied. Firstly, silver nanoparticles (Ag NPs) were synthesized using redox reaction method. To tightly stack NPs paste, with sizes 30~50 nm submicron-sized particles mixed. It found that increasing temperature or time can reduce porosity bonding...
