This article reports on an investigation into the ability of minced banana peel to extract lead and copper ions from water parameters involved in this process. The kinetics uptake reached equilibrium 10 min extraction metals was favorable above pH 3. medium characterized by FTIR, which showed absorption bands carboxylic amine groups at 1730 889 cm1, respectively. adsorption isotherm fitted Langmuir's model maximum capacities 0.33 0.20 mmol g−1 (or 20.97 41.44 mg g−1) for Cu(II) Pb(II),...
Bioactive peptides can provide health benefits due to different mechanisms. The aims of the present study are produce bioactive from bovine and goat milk subjected proteolytic activity Aspergillus oryzae flavipes enzymes, as well assess their putative antimicrobial antioxidant activity. were successfully generated proteases fungi cultivated in solid-state fermentation. effective against all tested bacteria fungi. There was activity, up 92.5% DPPH reduction ORAC stabilization at 52.5 μmol...
Abstract Understanding the effect of pesticides on survival honeybee colonies is important because these pollinators are reportedly declining globally. In present study, we examined changes in head proteome nurse honeybees exposed to individual and combined (the fungicide pyraclostrobin insecticide fipronil) at field-relevant doses (850 2.5 ppb, respectively). The proteomes bees were compared with those that not exposed, proteins differences expression identified by mass spectrometry....
In the present study, a simple, rapid and sensitive method was developed for determination of mercury concentrations in muscle tissue fish from Brazilian Amazon using graphite furnace atomic absorption spectrometry (GFAAS) following acid mineralization samples an ultrasonic cold water bath. Using copper nitrate as chemical modifier solution sodium tungstate permanent modifier, we were able to attain thermal stabilization up atomisation temperature 1600 °C GFAAS assay. The calculated limits...
This paper describes the synthesis and characterization of p-aminobenzoic modified cellulose (Cell-PAB), as well separation preconcentration Cd(II), Cu(II), Ni(II), Pb(II) Zn(II) ions from an aqueous medium using a Cell-PAB bath column technique. The quantity groups attached to surface, i.e., 1.81±0.04 mmol/g, was determined by elemental analysis. FT-IR spectra revealed characteristic bands groups, indicating desired functionalization surface. adsorptive capacities for metals (Ns) Cd, Cu,...
Abstract It is important to understand the cellular and molecular events that occur at cell–material interface of implants used for bone repair. The mechanisms involved in initial stages osteoblast interactions with surface implant material must be decisive cell fating surrounding them. In order address this issue, we decided investigate if conditioned medium dental was able modulate murine pre‐osteoblast metabolism. First, determined concentration titanium (Ti)‐containing found it 2‐fold...
Pequi oil (PO) is a natural feed additive rich in bioactive compounds, which can modulate antioxidant and immunological systems. Thus, the aim of this study was to evaluate proteomic profile laying hens supplemented with PO under heat stress conditions. Ninety-six 26-week-old Lohmann White were housed completely randomized design 2 × factorial arrangement, two climate chambers (cyclic thermoneutral) diets (control 0.6% PO). At 38 weeks old, liver samples collected for protein extraction...
ABSTRACT 5-amino-1,3,4-thiadiazole-2-thiol groups attached on a silica gel surface have been used for adsorption of Cd(II), Co(II), Cu(II), Fe(III), Ni(II), Pb(II) and Zn(II) from aqueous solutions. The capacities each metal ion were (in mmol.g−1): Cd(II)= 0.35, Co(II)= 0.10, Cu(II)= 0.15, Fe(III)= 0.20, Hg(II)= 0.46, Ni(II)= 0.16, Pb(II)= 0.13 Zn(II)= 0.15. modified was applied in the preconcentration quantification trace level ions present water samples (river, bog water). Keywords::...
Oxigênio dissolvido (OD), demanda bioquímica do oxigênio (DBO) e química (DQO) foram utilizados como parâmetros para se avaliar o grau capacidade de autodepuração ribeirão Lavapés, que atravessa a cidade Botucatu - SP. Avaliou-se perfil poluição orgânica identificadas as zonas autodepuração, pontualmente foi realizado uma coleta 24 horas, hora em hora, onde possível correlacionar com atividades domésticas. A DQO mostrou-se melhor técnica orgânica, identificar depuração, neste curso d’água....
A 90-day feeding experiment was conducted with sex reversed Nile tilapia (Oreochromis niloticus) fingerlings fed purified or practical diets supplemented different zinc sources to evaluate fish growth performance and iron retention in bones, fillets, liver, skin eyes. The relative bioavailability value (RBV) of the supplemental tested also calculated. Fish were isonitrogenous isoenergetic 150 mg Zn kg−1, as sulphate monohydrate (ZnSO4), oxide (ZnO) amino acid complex (Zn-AA). trial 30, 50 L...
Subcutaneous fat deposition measured as backfat thickness (BFT) increases protection for the bovine carcass during cooling, conferring to BFT an important characteristic meat industry. To study influence of on quality traits Nellore bulls (Bos indicus), data from 1652 animals aged 20–24 months in feedlot finishing were used. The principal component analysis (PCA) was performed characterise variables longissimus thoracis muscle. Measurements comprised rib eye area, BFT, marbling, shear force,...
