in this research, (carboxy-3-oxopropylamino)-3-propylsilylcellulose (copapsc) as an organocatalyst, has been synthesized by grafting of succinic anhydride on the nh2-modified cellulose (cellulose functionalized with 3- aminopropyltriethoxysilane). the –co2h group-functionalized cellulose (copapsc) is used as a catalyst for the synthesis of coumarin derivatives from the reaction of phenolic subs...

micrornas (mirnas) are a class of small non coding regulatory rnas that have key functions in multiple cell processes. deregulation of these tiny mirnas are involved in various human diseases. mir-155 is one of the multifunctional mirna that its over-expression has been found to be associated with different kinds of cancer such as leukemia, breast and colon cancers. it is thought that deregulat...

objective(s): this study focused on determining cytotoxic effects of copper oxide nanoparticles (cuo nps) on chronic myeloid leukemia (cml) k562 cell line in a cell-specific manner and its possible mechanism of cell death. we investigated the cytotoxicity of cuo nps against k562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). materials and methods: the toxicity w...

phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...

3-(2-furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula r3snl (r=me, et, n-bu, ph and cy) and r2snl2 (r=me and n-bu). these complexes have been characterized by elemental analyses, ir, 1h-nmr, mass and mössbaure spectroscopy.

purpose: to review on outcomes of phosphorus-32 ( 32 p) intracavitary irradiation for craniopharyngiomas. methods: a literature review of all full publications in english biomedical journals (1981-2014) was performed. the search strategy included a combination of key words “phosphorus-32”, “craniopharyngioma”, “intracystic treatment”, “brain”, “cyst”, “tumor”, “brachytherapy”, “intracavitary ir...

aim : this study evaluated the association between serum endothelin- 1 level and symptoms, clinical examination, laboratory and cardio-respiratory parameters, in patients with cirrhosis compared to controls. background : cirrhosis is associated with significant portal, pulmonary and systemic vascular abnormities. recent studies have suggested that endothelin -1 may have a significant role in th...

cognitive models of obsessive-compulsive disorder (ocd) posit that specific kinds of dysfunctional beliefs underlie the development of this disorder. the aim of present study was to determine whether these beliefs are endorsed more strongly by ocd patients than by those with other anxiety disorders and by community samples. a battery of questionnaires, including the obq-44, moci, bdi-ii, bai, s...
