in this report, synthesis, characterization and application of silica perchloric acid nanosphere as a novel and heterogeneous catalyst is described. these nanospheres have been characterized by xrd, ft-ir, bet and tga spectra and also by sem and tem images. the results show that it has a spherical shape and the particles size are between 75 and 100 nm. the catalytic activity has been investigat...

background: periodontitis is a multifactorial chronic inflammatory disease characterized by destruction of tooth-supporting tissues. environmental and genetic factors as well as the immune system participate in this process. recent studies have attempted to elucidate the role of cytokine networks involved in periodontal diseases. objective: to assess and compare the levels of il-4, il-6 and il-...

a new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. the synthesised compounds have been screened in vitro for their antimicrobial acti...

the composition of the essential oils of nepeta crispa willd. and n. menthoides boiss. and buhse (lamiaceae) was investigated by means of gas chromatography (gc) and gc- mass spectrometery (ms). 1, 8-cineole was the most abundant component in oils: nepeta crispa (71%) and n. menthoides (41.1%). in the oil of n. crispa, b-pinene (5%) and d-terpineol (4.1%) were found to be the major constituents...

hiv-1 integrase (in) enzyme, one of the three main enzymes of hiv-1, catalyzed the insertion of the viral dna into the genome of host cells. because of the lack of its homologue in human cells and its essential role in hiv-1 replication, in inhibition represents an attractive therapeutic target for hiv-1 treatment. since identification of in as a promising therapeutic target, a major progress h...

In Greece gold searchers and lost treasures, are very common because there are too many gold deposits, too many lost gold coins, from the World War II, and generally too many lost treasures dating from the Byzantine period, the Ottoman Empire as well as treasures regarding pirates, Venetians etc. Gold searchers, despite the strenuous efforts they make to detect some of the lost treasures, very ...

beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. according to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (beta-2 adrenocep...

our study performed upon an extended series of 28 compounds of 1,2,4-triazole derivativesthat demonstrate substantial in vitro antimicrobial activities by serial plate dilution method,using quantitative structure-activity relationship (qsar) methods that imply analysis ofcorrelations and multiple linear regression (mlr); a significant collection of moleculardescriptors was used e.g., edge adjac...
