Burkitt lymphoma is a rare malignancy arising from B cells. Current chemotherapeutic regimens achieve excellent overall survival rates in children, but less impressive rates in adults. There are cases with poor outcome caused by toxic effects of the therapy, tumor lysis syndrome, or metastatic spread of lymphomas to the central nervous system. Modulators of reactive oxygen species are currently...
This study reports the capacities and mechanisms of live biomass of an ascomycetes strain, Aspergillus niger HM11 biomass preparations in removing a textile dye Reactive blue 140 from aqueous solution was investigated with different parameters, such as adsorbent dosage, pH, initial dye concentrations and equilibrium time. pH study and desorption profile proved that adsorption process was suppor...
immobilization of catalysts on the surface of some inert supports makes therecovering step easier. because of the specific physicochemical properties, zeolites are good candidate as catalyst supports. in this study, zeolite x was synthesized by natural kaolin and tio2 was incorporated into zeolite phase by impregnation method. degradation of safranin orange, methylene blue and 2,4–dinitroanilin...
Developing reusable, sustainable and long term storable bioremoval technologies is essential for removal of heavy metals reactive dyes in industrial wastewater. <i>Clavibacter michiganensis</i> (<i>C. michiganensis</i>) having bioremediation property was selected attachment, polysulfone (PSU) as the polymer matrices electrospinning nanofibrous webs. For this approach, na...
Yeast hexokinase, a homodimer (100 kDa), is an important enzyme in the glycolytic pathway. Although Cibacron Blue 3G-A (Reactive Blue 2) has been previously shown to inactivate yeast hexokinase, no comprehensive study exists concerning the nature of interaction(s) between hexokinase and the blue dye. A comparison of the computer-generated three-dimensional (3D) representations showed considerab...
Electrospun materials, due to the possibility of design their properties, are suitable as supports for enzyme immobilization. Produced biocatalytic systems might be then apply in various reactions, including conversion pollutants. In our study, electrospun fibers made from nylon 6 was produced, modified and applied a support laccase immobilization by adsorption covalent binding. The with immobi...
Zinc hydroxide chloride nanostructure was successfully synthesized through a simple method at low temperature by sonochemical process. The morphology and crystalline of the products were analyzed by XRD, FESEM and TEM. The effect of independent variables including contact time, solution pH, adsorbent dosage and the concentration of dyes on response performance with response to surface methodolo...
We examined bovine aortic endothelial cells (BAECs) for the functional expression of P2X receptors, the ATP-gated cation channels. We identified the P2X subtypes present in BAECs using RT-PCR. mRNA was present for only three of seven family members: P2X4, P2X5, and P2X7. We then characterized agonist-activated currents in whole cell and outside-out patch recordings using 2-methyl-thio-ATP (MeSA...
Studies were carried out on the photodynamic inactivation of Bacillus subtilis cells by He-Ne laser irradiation in presence of methylene blue and toluidine blue. Electron paramagnetic resonance (EPR) measurements show decrease in the cell membrane nuidity due to photodynamic damage of the lipophilic compartments. Study of cell damage in presence of sodium azide, 0 20 and glutathione as well as ...
PURPOSE To localize tubby-like protein 1 (TULP1) in developing and adult human retinas. METHODS TULP1 was localized by immunofluorescence microscopy in human retinas, aged 8.4 fetal weeks to adult. TULP1-positive cells were identified by double labeling with antibodies specific for cones, rods, and astrocytes. RESULTS In adult retinas, anti-TULP1 labels cone and rod inner segments, somata, ...
