13. Determination of disulfide bridges of two spider toxins: hainantoxin-III and hainantoxin-IV
Peptide toxins are usually highly bridged proteins with multipairs of intrachain disulfide bonds. Analysis of disulfide connectivity is an important facet of protein structure determination. In this paper, we successfully assigned the disulfide linkage of two novel peptide toxins, called HNTX-III and HNTX-IV, isolated from the venom of Ornithoctonus hainana

14. PurificaÃÃo, caracterizaÃÃo de uma lectina e compostos fenÃlicos da entrecasca de Sebastiania jacobinensis (Muill. Arg.): efeito de radiaÃÃo gama sobre estrutura-atividade protÃica e proteÃÃo de flavonÃides isolados
A lectin from Sebastiania jacobinensis bark (SejaBL) was isolated using a combination of acetone precipitation, fractionation by ammonium sulphate, ion exchange and gel filtration chromatographies. The molecular mass of SejaBL was determined as approximately 52.0kDa by SDS-PAGE and 50.0kDa by gel filtration. The lectin is a glycoprotein with a neutral carboh

15. Characterization of chromosome rearrangements in patients with multiple congenital malformation and/or mental retardation (MCM/MR) / Caracterização de rearranjos cromossômicos em pacientes com malformações congênitas múltiplas e/ou retardamento mental (MCA/MR)
Two apparently "de novo" balanced translocations and one duplication of the short arm of chromosome 20 were studied. Our aim was to determine the breakpoints by chromosomal analysis through fluorescentin situ hybridization (FISH) and identify candidate genes and how they were involved with the clinical phenotypes of the patients. Patient 1 carried a duplicat

16. Controle alternativo da antracnose no maracujá-amerelo na pós-colheita / Controle alternativo da antracnose no maracujá-amerelo na pós-colheita
Vários fungos causam doenças no maracujá-amarelo na fase de pós-colheita, principalmente Colletotrichum gloeosporioides que provoca lesões nas frutas, prejudicando a comercialização. Entre os métodos alternativos de controle de doenças pós-colheita a indução de resistência sistêmica com elicitores bióticos e abióticos é uma alternativa promi

17. Strutural characterization of hypothetical proteins complex - XACb0032/XACb0033 from Xanthomonas axonopodis pv. citri / Caracterização estrutural do complexo de proteinas hipoteticas - XACb0032/XACb0033 da bacteria Xanthomonas axonopodis pv. citri
Xanthomonas axonopodis pv. citri (Xac) is the causative agent of citrus canker, a disease of significant economic importance worldwide. The molecular bases of the virulence mechanism are still unknown, but is believed that transfer of bacterial virulence proteins directly into the host cell cytoplasm is mediated by protein secretion systems, mainly type III

18. 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

19. Estudo da síntese convergente de peptídeos em fase sólida: abordagem clássica e uso de temperatura alta / Study of the convergent solid phase peptide synthesis: classical approach and use of high temperature
Stepwise solid-phase peptide synthesis (SSPPS) has been applied successfully for the preparation of most peptides containing up to 30 residues. However, it presents problems and limitations. Convergent soIid-phase peptide synthesis (CSPPS) can overcome part of them. This methodology is based on the synthesis of peptide segments by SSPPS followed by their con

20. Pupil size following dark adaptation in patients with retinitis pigmentosa
According to the equivalent light hypothesis, molecular defects in the photoreceptor lead to a continuous activation of the photoreceptor cascade in a manner equivalent to real light. The consequences in diseases such as retinitis pigmentosa (RP) are as disruptive to the cells as real light. Two forms of the equivalent light hypothesis can be distinguished:

21. Characterization of constitutive and putative differentially expressed mRNAs by means of expressed sequence tags, differential display reverse transcriptase-PCR and randomly amplified polymorphic DNA-PCR from the sand fly vector Lutzomyia longipalpis
Molecular studies of insect disease vectors are of paramount importance for understanding parasite-vector relationship. Advances in this area have led to important findings regarding changes in vectors' physiology upon blood feeding and parasite infection. Mechanisms for interfering with the vectorial capacity of insects responsible for the transmission of d

22. Miotoxinas PLA2 "like" de Bothrops pirajai : caracterização molecular e funcional
The genus Bothrops comprises severaI species, which are widely distributed in South and North America. Among the bioactive proteins from Bothrops venoms, the phospholipase A2(PLA2,E.C.3.1.14) and PLA2-likemyotoxin are outstanding as their major components. Phospholipase A2Sare calcium-dependent enzymes which hydrolyze the 2 ester bonds of 1,2 diacyl-3sn phos

23. Celulas esplenicas secretoras de imunoglobulinas e anticorpos sericos em camundongos Swiss livres de patogenos especificos inoculados com Yersinia enterocolitica O:3 ou derivados
A infecção por Yersinia enterocolitica O:3 é uma dentre várias patologias humanas causadas por bactérias gram-negativas, que pode resultar em um quadro de doenças autoimunes, entre elas a artrite reativa. A ativação policIonal de células B tem sido um dos mecanismos propostos que levaria a um aumento de produção de imunoglobulinas autoreativas e p

24. Importins fulfil a dual function as nuclear import receptors and cytoplasmic chaperones for exposed basic domains
Many nuclear transport pathways are mediated by importin β-related transport receptors. Here, we identify human importin (Imp) 4b as well as mouse Imp4a, Imp9a and Imp9b as novel family members. Imp4a mediates import of the ribosomal protein (rp) S3a, while Imp9a and Imp9b import rpS7, rpL18a and apparently numerous other substrates. Ribosomal proteins, his
