the dispersibility of graphene is modeled as a mathematical function of the molecular structure of solvent represented by simplified molecular input-line entry systems (smiles) together with the graph of atomic orbitals (gao). the gao is molecular graph where atomic orbitals e.g. 1s1, 2p4, 3d7 etc., are vertexes of the graph instead of the chemical elements used as the graph vertexes in the tra...
This study concerns the genetic diversity and taxonomic status of Marrubium species from central and south-west of Zagros region, Iran. It is investigated by Inter-Simple Sequence Repeat analysis. A total of 68 accessions from five Marrubium species were collected from their natural habitats. Molecular analysis was approved with 17 primers, of which 12 were carried out in the reaction mixture. ...
The Coffin-Lowry syndrome (CLS) is a rare X linked disorder in which affected males show severe mental retardation with characteristic dysmorphism, most notably affecting the face and hands. The typical facial features consist of a prominent forehead, hypertelorism, a flat nasal bridge, downward sloping palpebral fissures, and a wide mouth with full lips. Mild progression in facial coarsening o...
Objective: The aim of the study was to analyze a series of Brazilian patients suffering from MELAS. Method: Ten patients with MELAS were studied with correlation between clinical findings, laboratorial data, electrophysiology, histochemical and molecular features. Results: Blood lactate was increased in eight patients. Brain image studies revealed a stroke-like pattern in all patients. Muscle b...
Malignant transformation of B cells can occur at various steps of lymphocyte development, starting from early B-cell progenitors up to mature B cells, which reflects the heterogeneity of B-cell malignancies with regard to their biologic and clinical behavior. The genetic characterization of B-cell neoplasms during the past two decades has elucidated the mechanisms underlying B-cell lymphomagene...
In mammals, pluripotent stem cells can give rise to every cell type of embryonic lineage, and hold great potential in regenerative medicine and disease modeling. Guided by the mechanism underlying pluripotency, pluripotent stem cells have been successfully induced through manipulating the transcriptional and epigenetic networks of various differentiated cell types. However, the factors that con...
In his book The Sleepwalkers, Arthur Koestler commented on how scientific progress has evolved along much more irregular paths than generally realized. During the past 100 years, deciphering the pathogenic effects of microorganisms and discovering the many important bacterial toxins represent another case Koestler might have drawn. Some of the most important achievements in the loo-year story o...
microRNAs (miRNAs) are small noncoding endogenously produced RNAs that play key roles in controlling the expression of many cellular proteins. Once they are recruited and incorporated into a ribonucleoprotein complex miRISC, they can target specific mRNAs in a miRNA sequence-dependent process and interfere in the translation into proteins of the targeted mRNAs via several mechanisms. Consequent...
