[Ab] Resumo:The most specific method of the recording of the rate offree radical reactions is the method of electron paramagnetic resonance (EPR) spectroscopy, but it is rarely used in applied biology due to expensive equipment and complexity of the execution of measurements. However chemists have found a number of colored organic radicals which lose the coloring under transition into diamagnetic form. In the given paper there are presented results of our studies on the development of methods for the assessment of oxidant equilibrium in biological media with a use of stable radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and cation-radicals of N,N-diethyl-p-phenylenediamine (DEPPD). We have developed the new modification of DPPH test, replacing methanol-based incubation medium by non-ionic detergent solution, compatible with native blood serum. Modified DPPH test conserved typical biphasic kinetics of the origin variant, had the similar sensitivity to model antioxidants (IC values 49, 38 and 13 mkMfor ascorbate, a-tocopherol and quercetine, correspondingly) and was applied in experiments on laboratory animals treated with nano- and ionic silver, carbon nanotubes, microfine coal and electrolytic dust. We have tried also the assay of serum lipid hydroperoxides based on Fe-initiated DEPPD oxidation (Alberti et al., 2000). The comparison of kinetics of DEPPD oxidation in model (HO/Fe) and biologic (rat serum/Fe) systems, before and after Fe addition, seems to be an evidence that ceruloplasmin (CP) was involved in the resulting process, but failed to determine its polynomial kinetics, at least for the rat serum and DEPPD excess. The use of CP monoclonal antibodies seems to be the best way for the clarification of the mechanism of this reaction.

[Ti] Título:Effect of CRABP2 on the proliferation and odontoblastic differentiation of hDPSCs.

[Ab] Resumo:Cellular retinoic acid-binding protein 2 (CRABP2) has been detected in several organs during embryonic development. Recent studies have demonstrated that CRABP2 plays important roles in the retinoic acid, ß-catenin and Notch signaling pathways, as well as in the interaction between epithelial and mesenchymal cells, which are important for human dental pulp stem cells (hDPSCs) and tooth development. In the present study, the expression of CRABP2 during mouse molar development and the role of CRABP2 in hDPSC odontoblastic differentiation were evaluated. CRABP2 was gradually decreased during the development of the first maxillary molar, which exhibited the same trend as the expression of CRABP2 during the odontoblastic induction of hDPSCs. CRABP2 knockdown inhibited the proliferative ability of hDPSCs, while it enhanced odontoblastic differentiation via promoting mineralization nodule formation and upregulating the activity of alkaline phosphatase and the expression of mineralization-related genes. The present study uncovered a novel function of CRABP2 in hDPSCs. Our data suggest that CRABP2 may act as a regulator during the proliferation and differentiation of hDPSCs.

[Ab] Resumo:The aim of this study was to select optimal conditions (C and N sources, initial pH and temperature) for biodecolorization of 0.03% anthraquinone dye Alizarin Blue Black B (ABBB) by microscopic fungi: Haematonectria haematococca BwIII43, K37 and Trichoderma harzianum BsIII33. The phenolic compounds, phytotoxicity (Lepidium sativum L.), biotoxicity (Microtox), cytotoxicity and yeast viability assay were performed to determine the extent of ABBB detoxification. Biodecolorization and detoxification of 0.03% ABBB in H. haematococca BwIII43 and T. harzianum BsIII33 cultures was correlated with extracellular oxidoreductases activity. In turn, secondary products, toxic to human fibroblasts and respiring sod1 Saccharomyces cerevisiae cells, were formed in H. haematococca K37 strain cultures, despite efficient decolorization.

[Ab] Resumo:In this study, graphene oxide - cellulose nanowhiskers nanocomposite hydrogel was easily synthesized through covalent functionalization of cellulose nanowhiskers with graphene oxide via a facile approach. The nitrene chemistry applied for covalent functionalization of graphene oxide sheets. The surface morphology and chemical structure of the nanocomposite hydrogel were characterized by FTIR, TGA, Raman, XRD, elemental analysis and SEM. The UV/Visible absorption spectrum revealed that the obtained porous nanocomposite hydrogel can efficiently remove cationic dyes such as methylene blue (MB) and Rhodamine B (RhB) from wastewater with high absorption power. The adsorption process showed that 100% of MB and 90% of RhB have been removed and the equilibrium state has been reached in 15min for low concentration solutions in accordance with the pseudo-second-order model. Moreover, the sample exhibited stable performance after being used several times. High adsorption capacity and easy recovery are the efficient factors making these materials as good adsorbent for water pollutants and wastewater treatment.

[Ab] Resumo:This study analysed the use of sophora flower bud extract for dyeing and the resulting colour character and fastness of dyed silk fabric. The pigment composition on the silk fabric and recycling of this extract were also studied. The results indicated that the dyed silk fabric possessed good washing, rubbing and perspiration fastness, and the pigment composition on the silk fabric was mainly rutin and quercetin. The average recovery rate of the dye was 55.00%. These results demonstrate that the sophora flower bud extract is an effective natural dye.

[Ab] Resumo:Degradation of commercial grade Reactive Black 5 (RB5) azo dye by chemical and electrochemical treatment was examined using a dimensionally stable anode and stainless steel cathodes as electrode materials, with NaCl as supporting electrolyte. The electrochemical treatment was compared to the chemical treatment with hypochlorite generated by electrolysis. The compounds present in the commercial grade RB5 azo dye and the products of its electrochemical degradation were separated using ion-pairing high performance liquid chromatography on reversed phase. The separated species were detected by diode array detector and electrospray ionization mass spectrometry. A suitable ion-pairing reversed phase HPLC-MS method with electrospray ionization for the separation and identification of the components was developed. The accurate mass of the parent and fragment ions were used in the determination of the empirical formulas of the components using the first-order mass spectra. Structural formulas of degradation products were proposed using these information and principles of organic chemistry and electrochemistry.

[Ab] Resumo:Brassica oleracea L. var. capitata f. rubra (Red Cabbage) dye is composed mainly of natural pigment called anthocyanins used as a natural colourant. Wool and silk fibres were dyed with the aqueous extract obtained from red cabbage. The dyeing process was investigated and the combined effects of dyeing conditions on the colour yield parameter (K/S) were studied. Resulted fastness to wash, rubbing and light of the dyed fabrics were evaluated. Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD of the residual effluent were measured. Best dyeing conditions were found to be: 50 g/100 mL, pH 2, 60 min and 100 °C, respectively, for the red cabbage weight, pH, dyeing duration and temperature. Good fastnesses properties were found in both cases: for wool and silk fabrics. It was found also that the calculated biodegradability ratio (COD/BOD ) of the residual bath of dyeing wool and silk with red cabbage extract are lower than 1.5 which means that these baths are biodegradable.

[Ab] Resumo:OBJECTIVE: To retrospectively evaluate the feasibility of CT fluoroscopy-guided percutaneous marking using a 25-gauge needle and indigo carmine before video-assisted thoracoscopic surgery (VATS) for small lung lesions. METHODS: 21 patients, 14 males and 7 females, with a median age of 69 years (range, 40-79), underwent CT fluoroscopy-guided percutaneous VATS marking using a 25-gauge, 70-mm needle and 1.5-ml indigo carmine. The mean diameter of the lung lesions was 14 mm (range, 6-27). We evaluated the technical success rate, surgical success rate and complications related to this procedure by reviewing medical records and images. Technical success was defined as completion of this procedure. Surgical success was defined as resection of the target lesion with negative margins on pathological examination after VATS. Complications that required advanced levels of care were classified as major complications, and the remaining complications were considered minor. RESULTS: The technical success rate was 100%. In all cases, VATS was successfully performed as planned, and the target lesion was resected with negative margins on pathological examination after VATS. Thus, the surgical success rate was 100%. Mild pneumothorax was found in two cases, but further treatment was not required. The minor complication rate was 9.5% (2/21), and major complication rate was 0%. Only two patients (9.5%) complained of slight pain upon puncture, but local anaesthesia was not required. CONCLUSION: Percutaneous CT fluoroscopy-guided VATS marking using a 25-gauge needle without local anaesthesia appears feasible and safe. Advances in knowledge: This technique expands a possibility of the CT-guided marking.

[Ab] Resumo:A study was carried out to investigate the degradation of organic contaminants (Congo red and Reactive yellow - 105) using cellulose acetate - polystyrene (CA-PS) membrane with and without ZnO impregnation. Scanning electron microscope (SEM), electron dispersive analysis of X-rays (EDAX), Fourier transform infrared spectrometer (FTIR), atomic force microscope (AFM) and thermogravimeric analysis (TG-DTA) analysis were carried out to characterize bare and ZnO impregnated CA-PS membranes. Membrane efficiency was also tested for pure water flux and antifouling performance. The modified membrane showed almost 85% water flux recovery. Blending of ZnO nanoparticles to CA-PS matrix could decrease membrane fouling and increase permeation quality of the membrane with above 90% of photocatalytic degradation efficiency for dyes. The rate of degradation of dyes was observed using UV-Vis spectrometer. Reusability of CA-PS-ZnO membrane was studied and no significant change was noted in the degradation efficiency until fourth cycle. Langmuir-Hinshelwood kinetic model well describes the photo degradation capacity and the degradation of dyes CR and RY - 105 exhibited pseudo-first order kinetics. The regression coefficient (R) of CR and RY - 105 found to be 0.99. The novelty of the prepared CA-PS-ZnO membrane is that it has better efficiency and high thermal stability than our previously reported material. Therefore, ZnO impregnated CA-PS membrane had proved to be an innovative alternative for the degradation of CR and RY - 105 dyes.

[Ab] Resumo:In the present study, Curcuma longa (turmeric plant) was used as an adsorbent to remove Basic Green 1 (BG) dye. Batch study was carried out to evaluate the adsorption potential of C. longa and influencing factors such as pH (4-10), adsorbent dose (0.2-5 g l-1), initial dye concentration (50-250 mg l-1) and temperature (30-50°C) on dye removal were analysed. The characterisation of adsorbent was carried out using fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and Brunauer, Emmett and Teller (BET) method. Isotherm models that included Langmuir, Freundlich, Tempkin and Dubinin-Radushkevich, and kinetic models such as pseudo first order, pseudo second-order, Elovich and intraparticle diffusion models were studied. A maximum removal percentage (82.76%) of BG dye from aqueous solution was obtained with optimum conditions of pH 7, 1g l-1 adsorbent dose and 30°C temperature, for 100 mg l-1 initial dye concentration. The equilibrium and kinetic study revealed that the experimental data fitted suitably the Freundlich isotherm and Pseudo second order kinetic model. Thermodynamic analysis proved that adsorption system in this study was spontaneous, feasible and endothermic in nature.
