The molecular structure of any system may be unambiguously described by its adjacency matrix, A, in which bonds are assigned entry a(ij) = 1 and non-bonded pairs of atoms entry a(ij) = 0. For π-electron-containing conjugated hydrocarbons, this matrix may be modified in order to represent one of the possible Kekulé structures by assigning entry 1 to double bonds and entry 0 to single bonds, lead...

objective(s): the aim of this study was to investigate the methylation status and mrna expression levels of p15, death-associated protein kinase (dapk), and suppressor of cytokine signaling-1 (socs1) genes in multiple myeloma (mm). materials and methods: the bone marrow samples of 54 mm patients were collected and the methylation status of the p15, dapk, and socs1 gene promoter regions was dete...

conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...

La obtención de bioetanol es uno los retos más importantes en la generación biocombustibles amigables con el medio ambiente, búsqueda matrices que produzcan niveles altos este combustible representa un área estudio innovación tecnológica, donde desperdicio agroindustrial puede considerarse una alternativa para producción segunda a corto plazo evita incremento desperdicios vertederos y proporcio...

La nochebuena (Euphorbia pulcherrima Willd. ex Klotsch) crece de manera silvestre en los bosques tropicales mexicanos forma arbustiva y con brácteas rojas llamativas menor frecuencia presenta blancas. El uso principal la nativa es el ornamental, poco se ha estudiado acerca las propiedades nutrimentales o nutracéuticas planta. objetivo del presente estudio fue determinar perfil flavonoides ácido...

Using a simple but powerful geometrical/topological notion of aromaticity based on the shell model (Zdetsis, A. D. J. Phys. Chem. C 2018, 122, 17526–17536) and bipartite topology, we uncover, top geometrical virtual “equivalence” fundamental Hückel Clar rules aromaticity, significance empty peripheral rings, which are shown to be linked zigzag edge states. Such rings can thought as “inversion s...

in view of the fundamental role of genetics in development of obesity, the present study aimed to investigate the single nucleotide polymorphism of some obesity-related genes among a subset of obese women living in tabriz, iran. for this purpose, 70 eligible obese women (aged 18-45 years) were genotyped for the uncoupling protein-1 (ucp-1) -3826a>g, ß3-adrenergic receptor (ß3adr) trp64arg, lept...
