Isoenzymatic expression of Na, K-ATPase in Langerhans islets of glucose intoler...
Costa, Ana R; Capela e Silva, Fernando; Antunes, Célia M; Cruz Morais, Júlio MNa,K-ATPase is ubiquitously expressed in all eukaryotic cells where it acts as a regulator of Na+ and K+ homeostasis. The Na,K-ATPase pump consists of (αβ)22. The α-subunit contains the catalytic and ligand binding sites. The β-subunit is a glycosylated protein, and its role in Na,K-ATPase enzyme function remains somewhat obscure. Four α- and three β-isoforms have been described in mammals. The isoenzymatic exp...
Avaliação dos efeitos da acetilação nas propriedades das fibras de caroá
Lopes,Fernanda F. M.; Araújo,Gilmar T. de; Nascimento,José W. B. do; Vasconcelos,Robelsa F.; Dantas,Júlio M. E.As fibras de vegetais são altamente higroscópicas, característica que se apresenta como um dos principais problemas em sua aplicabilidade na produção de fibrocimentos, induzindo a variações dimensionais sob a influência da umidade, deposição dos produtos da matriz em seus poros e a degradação. Visando encontrar alternativas para minimizar os impasses gerados nos compósitos cimentíceos com relação às fibras de c...
A methodology for optimising the removal of cyanobacteria cells from a brazilia...
De Julio,M.; Fioravante,D. A.; De Julio,T. S.; Oroski,F. I.; Graham,N. J. D.This work is concerned with optimizing the performance of the coagulation process in terms of the removal of intact cyanobacteria cells and saxitoxins (STX). The evaluation has been carried out through bench-scale jar tests to construct coagulation diagrams for aluminium sulphate, polyaluminium chloride (PACl) and ferric chloride. The test water was taken from a eutrophic surface source, collected at the inlet ...
Composição química e atividade biológica de extrato oleoso de própolis: uma alt...
Buriol,Lilian; Finger,Daiane; Schmidt,Eduardo Morgado; Santos,Julio M. T. dos; Rosa,Marcos Roberto da; Quináia,Sueli Pércio; Torres,Yohandra ReyesPropolis is mostly used as hydroalcoholic extract. Recently there has been a growing number of patents dealing with new solvents for preparing propolis extracts. This study aimed to prepare edible oil propolis extracts and compare their chemical composition and biological activity with ethanolic propolis extracts. ESI-MS and spectrophotometric methods were used for qualitative and quantitative analyses, respect...
A straightforward multiallelic significance test for the Hardy-Weinberg equilib...
Lauretto,Marcelo S.; Nakano,Fabio; Faria Jr,Silvio R.; Pereira,Carlos A.B.; Stern,Julio M.Much forensic inference based upon DNA evidence is made assuming Hardy-Weinberg Equilibrium (HWE) for the genetic loci being used. Several statistical tests to detect and measure deviation from HWE have been devised, and their limitations become more obvious when testing for deviation within multiallelic DNA loci. The most popular methods-Chi-square and Likelihood-ratio tests-are based on asymptotic results and...
The effects of seasonal climate changes in the caatinga on tannin levels in Myr...
Monteiro,Júlio M.; Albuquerque,Ulysses P.; Lins Neto,Ernani M.F.; Araújo,Elcida L.; Albuquerque,Miracy M.; Amorim,Elba L.C.The influence of seasonal climatic changes on tannin concentrations was examined in two caatinga (semi-arid) plant species (Myracrodruon urundeuva (Engl.) Fr. All. and Anadenanthera colubrina (Vell.) Brenan). The Folin-Ciocalteau method was used to quantify total phenols, and the casein precipitation method was used for tannins. In general, there is a close relationship between tannin levels and rainfall, altho...
Kondo and Fano effect in side attached double quantum-dot molecule
Lara,Gustavo A.; Orellana,Pedro A.; Yáñez,Julio M.; Anda,Enrique V.Electron tunneling through a double quantum dot molecule side attached to a quantum wire, in the Kondo regime, is studied. The mean-field finite-U slave-boson formalism is used to obtain the solution of the problem. We investigate the many body molecular Kondo state and its interplay with the inter-dot antiferromagnetic correlation as a function of the parameters of the system.
Evolução ecocardiográfica de recém-nascidos com persistência do canal arterial
Afiune,Jorge Yussef; Singer,Julio M.; Leone,Cléa RodriguesOBJETIVO: Analisar características ecocardiográficas e manifestações clínicas na evolução de recém-nascidos pré-termo com persistência do canal arterial e identificar indicadores mais confiáveis do fechamento espontâneo deste. MÉTODOS: Sessenta e um recém-nascidos pré-termo com idade gestacional de 30±2 semanas (26-34 semanas) peso de 1,2±0,2 kg (0,7-1,7 kg) foram avaliados semanalmente desde o te...
Biodiversidade de moscas-das-frutas do gênero Anastrepha (Diptera, Tephritidae)...
Uramoto,Keiko; Walder,Julio M. M.; Zucchi,Roberto A.Este trabalho foi conduzido na área abrangida pelo campus da Escola Superior de Agricultura Luiz de Queiroz da Universidade de São Paulo, no município de Piracicaba, Estado de São Paulo. Teve como objetivos, determinar a composição do gênero Anastrepha Schiner e verificar a associação das espécies de plantas hospedeiras, estabelecidas na área, com as espécies de Anastrepha. Foram examinadas 23.277 fêmeas de Ana...
Fatal evolution of systemic lupus erythematosus associated with Crohn's disease
CHEBLI,Júlio M. Fonseca; GABURRI,Pedro Duarte; SOUZA,Aécio Flávio Meirelles de; DIAS,Kátia Valéria Bastos; CIMINO,Karla OliveiraThe authors describe the case of a young Brazilian woman who was treated of ileocolonic Crohn's disease sparing rectum, as confirmed by colonoscopy and histopathological examination. After a 4-year course of sulfasalazine treatment, she presented with skin facial lesions in vespertilio, fever, arthralgias and high titers of anti-ANA and LE cells. A sulfasalazine-induced lupus syndrome was diagnosed, because aft...
