Vanadium-modified (SiO2/MgO/MgCl2)•TiClx Ziegler-Natta catalysts were prepared through co-impregnation of water-soluble magnesium and vanadium salts under different pH values. Several key factors such as pH value of co-impregnation solution during catalyst preparation, catalyst performances including catalytic activity, ethylene/1-hexene copolymerization and hydrogen response were investigated....
Allergic Bronchopulmonary Aspergillosis (ABPA) is a hypersensitivity response to Aspergillus antigens in patients with asthma or cystic fibrosis (CF). The inhalation of spores from the environment is followed by growth of hyphae in the mucus of the bronchial tree and stimulates an immune response involving Th2 CD4+ T cells and IgE and IgG antibodies. Although diagnostic procedure for ABPA is a ...
Chronic Myeloid Leukemia (CML) is a hematopoietic malignancy characterized by the presence ofPhiladelphia (Ph1) chromosome that results from balanced reciprocal translocation between chromosomes9 and 22 leading in the formation of bcr/abl fusion gene. The present study was conducted to evaluate cytogenetic and molecular abnormalities in CML patients at presentation and during the co...
Background: Clinical evidence points to the effective role of genetic factors and intracellular signaling pathways in physiological cardiac hypertrophy. This study aimed to assess the response of PI3K/mTORc1 signaling pathway in cardiac tissue to resistance training in obese diabetic rats. Materials and Methods: For this purpose, 21 male wistar rats (220±20 g) were obese by 6 weeks high fat di...
Achievement of complete molecular response in patients with chronic phase chronic myeloid leukemia has been recognized as an important milestone in therapy cessation and treatment-free remission; the identification of predictors of complete molecular response in these patients is, therefore, important. This study evaluated complete molecular response rates in imatinib-treated chronic phase chro...
Before the advent of tyrosine kinase inhibitor (TKI) therapy, the evaluation of hematologic and cytogenetic responses was sufficient to gauge treatment efficacy in patients with chronic myeloid leukemia. However, with more potent TKI therapies, the majority of patients achieve complete cytogenetic response. Furthermore, deeper molecular responses are now commonly achieved, necessitating a relia...
Environmental stresses are ubiquitous and unavoidable to all living things. Organisms respond and adapt to stresses through defined regulatory mechanisms that drive changes in gene expression, organismal morphology, or physiology. Immune responses illustrate adaptation to bacterial and viral biotic stresses in animals. Dysregulation of the genotoxic stress response system is frequently associat...
We discuss several proposed explanations for the switching and negative differential resistance (NDR) behavior seen in some molecular junctions. Several theoretical models are discussed, and we present results of electronic structure calculations on a series of substituted oligo(phenylene ethynylene) molecules. It is shown that a previously proposed polaron model is successful in predicting NDR...
