1. Radiation Induced Synthesis of In2O3Nanoparticles - Part II: Synthesis of In2O3 Nanoparticles by Thermal Decomposition of Un-irradiated and γ-irradiated Indium Acetylacetonate
AbstractPure cubic phase, In2O3 nanoparticles with porous structure were synthesized by solid state thermal oxidation of un-irradiated and γ-irradiated indium acetyl acetonate in presence and absence of sodium dodecyl sulphate as surfactant. The as- synthesized In2O3nanoparticles were characterized by X-ray diffraction (XRD), fourier transformation infrared

3. Chemical modification of Aspergillus nigerβ-glucosidase and its catalytic properties
Aspergillus niger β-glucosidase was modified by covalent coupling to periodate activated polysaccharides (glycosylation). The conjugated enzyme to activated starch showed the highest specific activity (128.5 U/mg protein). Compared to the native enzyme, the conjugated form exhibited: a higher optimal reaction temperature, a lower Ea (activation energy), a h

4. Mycoremediation of Congo red dye by filamentous fungi
Azo, anthroquinone and triphenylmethane dyes are the major classes of synthetic colourants, which are difficult to degrade and have received considerable attention. Congo red, a diazo dye, is considered as a xenobiotic compound, and is recalcitrant to biodegradative processes. Nevertheless, during the last few years it has been demonstrated that several fung

5. Efeitos da atrazina e do duodecil sulfato de sódio sobre a estabilidade de eritrócitos humanos
CHAPTER II: This work evaluated the in vitro influence of albumin on the stability of human erythrocytes against the herbicide atrazine present in a commercially available preparation. The sigmoidally shaped curves, observed for the dependence between absorbance at 540 nm and the atrazine concentration in 9 g/L NaCl solution, were characterized by the midpoi

6. Experimental infection of commercial layers using a Salmonella enterica serovar Gallinarum strain: Leukogram and serum acute-phase protein concentrations
The aim of the present study was to evaluate white blood cell counts and serum protein profiles of commercial layers experimentally infected with Salmonella Gallinarum (SG) in order to better understand the pathophysiology of the disease caused by this bacterium. 180 five-day-old commercial layers were divided into 3 groups (G); G1 and G2 received 0.2 mL of

7. Proteinograma sérico de veados-catingueiro (Mazama gouazoubira) criados em cativeiro obtido por eletroforese em gel de agarose e de poliacrilamida (SDS PAGE)
The serum protein concentrations of brown brocket deer (Mazama gouazoubira) obtained by agarosis gel and sodium dodecyl sulphate-polyacrylamide (SDS-PAGE) gel were determined from blood samples of ten adult healthy animals (six females and four males), monthly collected in the morning, during 12 months. The animals, maintained in individual stable and protec

9. Proteinograma sérico de bezerros recém-nascidos da raça Holandesa obtido por eletroforese em gel de poliacrilamida
The serum protein concentration of newborn Holstein calves determined by means of sodium dodecyl sulphate-polyacrylamide (SDS-PAGE) was studied. Blood samples from 40 healthy newborn calves were obtained 48 hours after birth. Calves had been given 3 liters of colostrum within 2 hours after birth, following by dose corresponding by 15% of animal weight each 2

10. Efeitos da irradiação na composição e propriedades funcionais da soja. / Effects of irradiation on the composition and functional properties of soyben.
The aim of this work was to study the effects of both irradiation and storage on the chemical composition of soybean grains and on the physicochemical and functional properties of their protein isolates. The soy grains were divided into four lots, two of them were irradiated with of 60Cobalt source in doses of 2.0 or 5.0 kGy, a third one was irradiated with

11. Use of the paired samples (cerebrospinal fluid and serum) in immunodiagnostic of active and inactive human neurocysticercosis
Paired samples of cerebrospinal fluid (CSF) and serum of 30 patients - 10 with active, 10 with inactive neurocysticercosis (NCC), and 10 control subjects - were evaluated by enzyme-linked immunosorbent assay (ELISA) using two Taenia crassiceps metacestode extracts as antigen in order to detect IgG antibodies. In active NCC, high levels of IgG were detected (

12. Characterization of Sm14 related components in different helminths by sodium dodecyl sulphate-polyacrylamide gel electrophoresis and Western blotting analysis
Sm14 was the first fatty acid-binding protein homologue identified in helminths. Thereafter, members of the same family were identified in several helminth species, with high aminoacid sequence homology between them. In addition, immune crossprotection was also reported against Fasciola hepatica infection, in animals previously immunized with the Schistosoma
