ABSTRACT We report 26 complete genomes of Zika virus (ZIKV) isolated after passaging the Zika virus strain FLR in mosquito (C6/36) and mammalian (Vero) cell lines. The consensus ZIKV genomes we recovered show greater than 99% nucleotide identify with each other and with the FLR strain used as input.

Eupatorium odoratum (EO)contains many biologically active compounds, the anticancer effects of which are not well documented. This study evaluates the cytotoxic effects and mechanism of action ofEOextracts on MCF-7 and Vero cell lines. Evaluation of the cytotoxic activity using MTT assay, morphological alterations, and apoptosis were carried out. Autophagy was evaluated by LC3-A protein expression. Cytotoxic activity, membrane blebbing and ballooning at 24 hours, replacement by mass vacuolation, and double membrane vesicles mimicking autophagy and cell death were observed in the cancer cells. No apoptosis was observed by DNA fragmentation assay. Overexpression of LC3-A protein indicated autophagic cell death. Cell cycle analysis showed G0 and G2/M arrest. The Vero cells did not show significant cell death at concentrations <100 μg/mL. These results thus suggest that acetone and ethyl acetate extracts ofEOinduce cell death through induction of autophagy and hold potential for development as potential anticancer drugs.

Abstract Using the ultrasonic approach, we produced a morphology involving cerium oxide/ Zinc oxide/graphene oxide (CeO2/ZnO/GO) nanocomposite-based system. The developed nanocomposite was examined using X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy (FESEM). The average crystallite size was found to be 11.44 nm, as determined by XRD. FTIR analysis was used to confirm the existence of functional groups. FESEM was used to verify the morphological properties of CeO2/ZnO/GO. The micromorphology of CeO2/ZnO/GO nanocomposite reveals a smoother sheet-like structure. In addition, using an antiproliferative assay test, the developed nanosystem was evaluated for its scavenging anti-cancer capability against HeLa cell lines at various doses and incubation intervals. In our investigation, the effective IC50 concentration was reported to be 62.5 µg/ml at 72 h. Further, the developed nanosystem was evaluated for its killing efficacy against normal cell line. To identify apoptosis-associated alterations of cell membranes throughout the apoptosis process, a dual acridine orange/ethidium bromide (AO/EB) fluorescent staining was done using CeO2/ZnO/GO nanocomposite at three specific concentrations. The quantitative analysis was carried out using flow cytometry (FACS study) to determine the cell cycle during which the greatest number of HeLa cells were destroyed. According to the results of the FACS investigation, maximum cell cycle has taken place in P2, P4.As a result, the newly designed CeO2/ZnO/GO hybrid has demonstrated improved anti-cancer efficacy against the HeLa cell line, making it a better therapeutic agent for cervical cancer detection.
