objectives in this study, we reported the identification of a cdna sequence encoding cysteine-free antimicrobial peptides isolated from venomous glands of this species. materials and methods total rna was extracted from the iranian mesobuthus eupeus venom glands, and cdna was synthesized by using the modified oligo (dt). the cdna was used as the template for applying semi-nested rt- pcr techniq...

mcm-41 is one of the groups of mesoporous materials that have wide applications as adsorbents, ion exchangers and catalyst supports. in this work spherical and rod-like mcm-41s were synthesized in homogeneous and heterogeneous reaction media, respectively. for synthesis of these materials the cationic surfactant cetyltrimethylammonium bromide (ctmabr) was used as template and tetraethylorthosil...

introduction: evidence suggests that neuronal apoptosis in neurodegenerative diseases is correlated with inflammatory reactions. the beneficial or detrimental role of apoptosis in neuroinflammation is unclear. elucidating this question may be helpful in management of neurodegenerative diseases. since tnf-α is able to induce apoptosis as well as increased viability of the cells by activation of ...

in this study, removal of acid blue 62 from aqueous solution by mesoporous silicate mcm-41 modified by aminopropyltriethoxysilane (aptes) composite was studied. properties of synthesized composite were analyzed and confirmed by sem, edx and ftir. results show that langmuir adsorption isotherm has the best compatibility with the results of experiments. kinetic analysis using pseudo-first-order m...

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

ethanol known as ethyl alcohol is being widely used around the world. many serious diseases are related with its consumption.  alcohol posses many divers effects on human body including risk of cirrhosis and/or hepatocellular carcinoma. therefore, analysis of this component is prominent. fibroblast cells were cultured in various dosages of ethanol. the effective dosage was then investigated by ...

in this work, zeolite nay was prepared by hydrothermal method. then, silver ions were replaced in the zeolite nay with silver nitrate (agno3) solution via using ion exchange (ie) method. the manganese dioxide (mno2) nanoparticles (9.3 and 15.8 wt %) for guest were deposited in the zeolite agy(host) structure with mn(no3)2 aqueous and kmno4 solutions by confined space synthesis (css) method. syn...
