The research investigation was carried out in the experimental area of Sher-e-Bangla Agricultural university, Sher-e-Bangla Nagar, Dhaka-1207, during the late Rabi season Mid December to May 2018 to study the genetic diversity with cluster analysis for the 35 maize genotypes as experimental materials that were laid out in Randomized Complete Block Design (RCBD) with three replica-tions. The research work was oriented to calculate and estimate the yield fac-tor through analyzing genetic diversity involving the yield contributing characters. The maximum yield per plant (117.51 g) was estimated in the genotype G12 (Pacific) and the minimum yield per plant (51.89 g) was recorded in the genotype G17 (Dekalb Super). Due to the crossing among the 35 maize genotypes, a wide range of divergence was observed in this experiment. The highest genotypes were included in cluster number V with 12 genotypes: BHM-5, PAC-60, Pacific-98, HP-222, Khai Bhutta, AS-999, Pioneer, Duranta, Kaveri 218, Chamak-07 and Golden-984. Here, the intra cluster distance was observed in cluster I (1.23), II (0.00), III (0.76), IV (2.08) and V (1.89) respectively. The highest intra cluster was recorded in cluster IV (2.08) and the lowest in

Background: Nanotechnology symbolizes a broad discipline with enormous potential in cancer treatment bridging one of the bottlenecks of traditional approaches in cancer therapy which is an inability to deliver adequate quanti-ties of anti-cancer drugs to the tumor area. Studies on nanoparticles indicate their importance in cancer angiogenesis and metastasis. Aim: The present study assessed anti-angiogenesis and anti-metastatic effects of biogenic silver nanoparticles (AgNPs) synthesized from neem plant (Azadirachta indica). Methods: Chicken chorioallantoic membrane (CAM) and two-dimensional (2D) wound healing assays were used to study anti-angiogenic and an-ti-metastatic effects of the AgNPs respectively. Twenty-four fertilized eggs were divided into four groups: two biogenic AgNPs treatments at 100 µg/ml and 200 µg/ml; negative control (1% DMSO) and positive control (cyclo-phosphamide). 2D wound healing assay, DU145 human prostate cells were grown in Dulbecco’s Modified Eagle’s Medium supplemented with 10% Fetal Bovine Serum. Results: Biogenic AgNPs demonstrated anti-angiogenic effects in a dose-dependent manner in the parameters generated from the CAM images. Also, qRT-PCR revealed down-regulation of iNOS and VEGF genes. The 2-dimensional wound healing assay showed inhibition of migration and motility of the DU145 cells for the 72-hours of assessment. Conclusion: The present study postulates that the biogenic AgNPs can prevent angiogenesis by inactivation of VEGF-NO and VEGF/VEGF-R pathways while inhibiting cell migration and metastasis.
