A glucuronoarabinoxylan (CNAL) was extracted with 1% aq. KOH (25 °C) from Cocos nucifera gum exudate. It had a homogeneous profile on HPSEC-MALLS-RI (Mw 4.6 × 104 g/mol) and composed of Fuc, Ara, Xyl, GlcpA (and 4-O-GlcpA) in 7:28:62:3 molar ratio. Methylation data showed branched structure 39% non-reducing end units, 3-O-substituted Araf (8%), 3,4-di-O- (15%), 2,4-di-O- (5%) 2,3,4-tri-O-substituted Xylp units (17%). The anomeric region CNAL 13C NMR spectrum contained 9 signals, indicating...
Native polysaccharide from pineapple gum (PANP) was obtained following alkaline extraction of and fractionation with cetylpyridinium chloride. It characterized as a glucuronoarabinoxylan using NMR, methylation data, controlled Smith degradation, carboxy-reduction, ESI-MS oligosaccharides produced on mild acid hydrolysis PANP. HSPEC-MALLS-RI carboxy-reduced fraction showed homogeneous profile (Mw 1.943×10(5) g/mol). PANP composed Ara, Xyl, Gal, GlcpA (40:23:7:30 molar ratio). Its main chain...
This work sought to determine the two psychotropic drugs most commonly released by Psychosocial Care Centers (CAPS) into urban river waters (Belém sub-basin, Curitiba, PR, Brazil). A simple analytical method using SPE followed a HPLC–DAD was developed and validated. Strata-X® cartridges were used extract (carbamazepine) CZ diazepam (DZ) from water conditions optimized 23 factorial design. The validated specific for target compounds; correlation coefficients above 0.9998, recovery between...
Hot aqueous extraction of conidia Scedosporium prolificans gave a heterogeneous glycoprotein (RMP-Sp-Coni) with 41% protein and 2MeRha, Rha, Ara, Man, Gal, Glc, GlcNH2 in 2:18:3:47:9:15:6 M ratio, the first report 2-O-methylrhamnose fungi. Methylation analysis showed nonreducing end- (10%), 2-O- (11%), 3-O-substituted Rhap (7%), (8%), (12%), 3-O- (16%), 2,6-di-O-substituted Manp (9%), (4%), 4-O-substituted Glcp end-units Galp (9%). Mild reductive β-elimination RMP-Sp-Coni cleaved O-linked...
The increasing concern about the environment and population health leads to further research on water quality monitoring in Brazil, mainly terms of presence pharmaceutical chemicals compounds residues. Objective: To extensile review literature studies that quantifies micro emerging pollutants Brazilian waters order gather evidences provide information country. Methods: A systematic was conducted electronic databases PubMed, Science Direct, Scopus SciELO, along with manual search identify...
O uso de cabelo e pelo como amostras biológicas tem ganhado cada vez mais destaque na detecção drogas. Suas vantagens facilidade transporte, coleta não invasiva larga janela tornam essa matriz biológica perfeita para o nos exames toxicológicos. transporte rodoviário é predominante no Brasil, dentro disso, estão as extensas jornadas trabalho quais os motoristas sujeitos. Com isso, caminhoneiros começaram a exigir melhores condições trabalho, este fim foi criada em 2015, Lei nº 13.103/15,...
Spontaneous tumor regression is still one of the most puzzling events in human cancer. A cell culture model malignant transformation designed to permit study this phenomenon vitro was applied examine reversion and re-expression transformed phenotype two X-ray mouse 10T1/2 clones. By alternating passages at low high seeding density, expression contact inhibition tumorigenic capacity were both reverted restored. Growth non-transformed wild-type cells not affected by density. This associated...
Recently scientific community has turned its attention to the organic micropollutants such as pharmaceuticals and hormones, because ecotoxicological effects of chronic exposure are uncertain. These substances neither completely degraded nor monitored in sewage treatment, which makes aquatic environment main disseminant, due usual discharge domestic industrial sewage. Therefore, current work aims develop quantitative method using HPLC-UV-DAD-FLD detection order determine psychoactive drugs...
