background: viscerotropic leishmaniasis caused by leishmania tropica poses a significant prob­lem in the diagnosis and treatment management. since differential gene expression is more im­portant in outcome of the infection, we employed proteomic approach to identify potential pro­teins involved in visceralization of l. tropica . methods: the proteomes profiling of l. tropica isolated from cutan...

{sl let $[n]={1,dots, n}$ be colored in $k$ colors. a rainbow ap$(k)$ in $[n]$ is a $k$ term arithmetic progression whose elements have different colors. conlon, jungi'{c} and radoiv{c}i'{c} cite{conlon} prove that there exists an equinumerous 4-coloring of $[4n]$ which is rainbow ap(4) free, when $n$ is even. based on their construction, we show that such a coloring of ...

normal 0 false false false en-us x-none ar-sa background: exposure to some environmental agent such as different nutrition and contact with allergens may have a role in developing multiple sclerosis (ms). the present study was aimed to evaluate the cow’s milk allergy (cma) in ms patients compared to healthy controls. materials and methods: between march 2012 and july 2012, 48 ms patients were s...

in the present work, b-zsm-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. the tio2- bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. the uniform membrane intermediate layers with low permeation resistance were prepared o...

normal 0 false false false en-us x-none ar-sa background: alzheimer's disease (ad) is a progressive neurodegenerative disease in which endothelial cell (ec) can be affected. in brain, functional changes in ecs contribute to reductions in resting blood flow. furthermore, angiotensin-converting enzyme inhibitors (ace-i) have beneficial effects on endothelial dysfunction. this is the first study t...

the oxidation of low-density lipoproteins and cell membrane lipids is believed to play an integral role in the development of fatty streak lesions, an initial step in coronary artery disease (cad). paraoxonase-1 (pon1) is an enzyme associated with the high-density lipoprotein (hdl) particle. pon1 protects ldl from oxidative modification by hydrolyzing lipid peroxides, suggestive of a role for p...

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...

conclusions this study revealed that the administration of 600 μg of intravenous se immediately before induction of anesthesia was safe, but when compared to a placebo, no predominant clinical effects or modifications in the systemic inflammatory response induced by on-pump cabg were observed. results data from a total of 81 patients were analyzed: group s (n = 41) and group c (n = 40). there w...
