The fabrication of single phase monoclinic CuO was confirmed by XRD. SEM images showed the leaf like morphology for CuO which appeared rough and densely packed in CuO/NCQDs composites. TEM images of CuO/NCQDs shows slightly distorted nano-leaves with NCQDs dispersed on them. HRTEM of CuO/NCQDs shows fringes with characteristic planes confirming that the addition of NCQDs has not distorted the crystal structure of CuO. SAED of CuO/NCQDs further confirms the crystalline nature of the as synthesized composite photo catalyst by exhibiting bright diffraction rings. These results further supported the XRD data. EDS spectra of NCQDs and CuO/NCQDs confirm the formation of pure nitrogen doped carbon quantum dots and Cu, N, C and O atoms confirming that NCQDs are well incorporated on CuO Nano leaves. UV–Vis spectra showed a slight increase of band gap energies due to quantum confinement effects. PL spectra exhibited decreased photoluminescence intensity indicating suppression of recombination rate. The developed photocatalyst was applied for the degradation of harmful dye methyl orange. The composite catalyst s...

Hence, health insurance coverage could affect financial risk-taking by offsetting health-related background risk. We use a regression discontinuity design to examine whether Medicare eligibility at age 65 increases stockholding in the US and find that it does so for those with college educa...
In this study, serum IL6 was measured by ELISA, and the HSD11B1rs12086634(T/G) polymorphism was analyzed using a TaqMan allelic discrimination assay technique. There were statistically significant differences between the two studied groups concerning the serum IL-6 level and HSD11B1rs12086634(T/G) genotype distribution, with increased serum IL6 and increased frequencies of the GG and TG genotypes in patients with PCO. The GG genotype of HSD11B1 rs12086634(T/G) and its associated high level of serum IL-6 may represent genetic risk factors for PCOS.

ConclusionThe CFQL-2 is a brief, reliable scale that effectively measures psychosocial aspects of QoL and is sensitive to changes in QoL in families of children with ASD or related neurodevelopmental disorders. Child externalizing behavior is strongly associated with reductions in multiple aspects of child and family psychosocial QoL.
ConclusionThis meta-analysis suggested a significant association between MTHFR gene polymorphism (C677T and A1298C) and ASD risk.
ConclusionGiven that obtaining negative margins is important in reducing the risk of recurrence, the method of surgical resection utilized is based on the amount of future functional residual hepatic parenchyma.
ConclusionsTattooing of axillary LNs is safe and easily performed. Tattooing was helpful in identifying the marked LN in the majority of cases. This technique helps to ensure that metastatic LNs are identified and removed at surgery after NAT.
