tetrahydrobenzo[b]pyran derivatives 1 were utilized for the synthesis of several new pyrano[2,3-d]pyrimidine derivatives 2. compound 2 was obtained in the presence of ac2o/h2so4 (as a catalyst) and was confirmed by spectroscopic data such as ir, 1h nmr and 13c nmr. ab initio calculation was carried out to study geometric optimization, thermodynamic parameters, aromaticity and dynamic process of...

A knowledge-based approach to retrieve medical images by feature and content with spatial and temporal constructsk developed. Selected objects of interest in a medical image (e.g., x-ray, MR image) are segmented, and contours are generated from these objects. Features (e.g., shape, size, texture) and content (e.g., spatial relationships among objects) are extracted and stored in a feature and c...

evidences indicate that angiogenesis  is an important process in the development of destructive synovial tissue in rheumatoid  arthritis (ra). recently, it has been shown that the polymorphism of the integrin-αv subunit encoded by the itgav gene plays a role in angiogenesis and is considered  as ra susceptibility loci. this study investigated association of four single nucleotide polymorphisms ...

recently, it has been shown that a number of hydroxypyridinones such as 1,2-dimethyl-3-hydroxypyridin-4-one (l1) are useful for the treatment of iron overload in place of desferrioxamine in thalassaemic patients. in this study, the intestinal absorption (i.a.) of l1 and one of its analogues namely 2-methy-3-hydroxypyridin-4-one (l2), which possesses a higher partition coefficient (kpart) than l...

materials and methods: 32 new zealand rabbits were randomly divided into three groups: control group, high-cholesterol group and losartan group. the level of weights, serum lipid levels and inflammatory factors, such as il-6 and hs c-reactive protein were detected before the losartan intervention and two months after the losartan intervention respectively. the content of angii was detected on l...

background: rheumatoid arthritis (ra) is a chronic multisystem autoimmune disease common in all races and ethnics. cytokines and cytokines receptors play an important role in ra pathogenesis and clinical presentation. objective: to investigate the serum levels of tnf-α, tnf-α ri, tnf-α rii and il-12 in ra patients and healthy control group. methods: in this study 43 patients fulfilling the revi...

shortage of irrigation water, being a crucial problem in arid and semiarid regions, makes it necessary to use treated wastewater in agriculture. a field experiment was conducted to investigate the effect of treated municipal wastewater (tmw) on the yield and fiber quality of cotton (gossypium hirsutum l.) (mehr variety). treated municipal wastewater was supplied from shahrake ghods sewage treat...
