In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...

The diversity of fruit color in sweet cherry (Prunus avium L.) has been attributed to the presence either anthocyanin or carotenoid. We profiled and carotenoid metabolites investigate different pigments underlying regulatory mechanisms differential expression genes (DEGs) between red yellow fruits cherry. two cultivars, ‘Jiangnanhong’(JNH, fruits) ‘Chaoyang’(CY, establish their by LC-MS/MS tran...

Red-fleshed grapes are important breeding resources, and study of the content composition phenolic compounds in red-fleshed is lacking. In this study, profiles whole berry, flesh, peel thirteen grape (Vitis) accessions were determined for two consecutive years. The total ranged from 4.795 to 29.875 mg g−1 FW (fresh weight) 1.960 12.593 17.067 60.182 peel. As expected, anthocyanins main compound...

The utilization of natural extracts as an ingredient in cosmetic products becomes a better choice for customers. Rice berry has been defined potential source anti-free radical properties which is able to be formulated products. Therefore, the objectives this study are 1) investigate antioxidant by ABTS and assays, total compounds phenolic flavonoids cell viability fibroblast NIH3T3 (IC80) ethan...

Because of the recent global crises and lifestyle trends, anthocyanin-rich fruits are receiving more attention due to their medicinal qualities. Many studies have concluded that higher anthocyanin consumption tends correlate with health benefits. Furthermore, research has shown great promise for application in treating fever neurodegenerative processes. Once industrial difficulties solved, anth...

BACKGROUND Measuring genome size by flow cytometry assumes direct proportionality between nuclear DNA staining and DNA amount. By 1997 it was recognized that secondary metabolites may affect DNA staining, thereby causing inaccuracy. Here experiments are reported with poinsettia (Euphorbia pulcherrima) with green leaves and red bracts rich in phenolics. METHODS DNA content was estimated as flu...
