1. Quantificação de NBA?s provenientes da digestão ácida de materiais biológicos assistida por radiação micro-ondas.
O emprego de ácidos diluídos é uma alternativa viável para solubilização de materiais biológicos utilizando digestão assistida por radiação micro-ondas para a análise elementar por técnicas espectroanalíticas1. Como produtos de decomposição, vários compostos orgânicos foram descritos na literatura, sendo que os isômeros do ácido nitrobenz�

2. Genetic diversity of carotenoid-rich bananas evaluated by Diversity Arrays Technology (DArT)
The aim of this work was to evaluate the carotenoid content and genetic variability of banana accessions from the Musa germplasm collection held at Embrapa Cassava and Tropical Fruits, Brazil. Forty-two samples were analyzed, including 21 diploids, 19 triploids and two tetraploids. The carotenoid content was analyzed spectrophotometrically and genetic variab

3. "Identificação de produtos de reação presentes em soluções resultantes de digestões ácidas de amostras agronômicas" / Identification of reaction products in solutions produced by acid digestions in agronomic samples
Entre as diferentes formas empregadas para o preparo de amostras orgânicas visando a determinação de elementos inorgânicos, uma alternativa que foi avaliada neste trabalho foi a digestão assistida por radiação microondas empregando ácidos diluídos. Estudos recentes demonstram ser essa uma alternativa eficiente no tocante à solubilização de elemen

4. The inactivating K+ current in GH3 pituitary cells and its modification by chemical reagents.
1. Whole-cell and single-channel recording techniques were applied to the study of the permeability and gating of inactivating K+ channels from clonal pituitary cells. 2. The cation selectivity sequence (measured from reversal potentials) for the channels underlying the inactivating K+ current was Tl+ greater than K+ greater than Rb+ greater than NH4+. The c

5. Inactivation of the cloned potassium channel mouse Kv1.1 by the human Kv3.4 'ball' peptide and its chemical modification.
1. This study used the whole-cell patch clamp technique to investigate the action of a 28-mer 'inactivation peptide' based on part of the N-terminal sequence of the human Kv3.4 K+ channel (hKv3.4 peptide) on the cloned mouse brain K+ channel mKv1.1 expressed in Chinese hamster ovary (CHO) cells, and compared this with the inactivation produced by Shaker B in

6. Dynamics of strychnine block of single sodium channels in bovine chromaffin cells.
The kinetics of strychnine block of single Na channels in bovine chromaffin cells were studied using the gigohm seal, patch-clamp technique, under the condition in which the Na current inactivation had been eliminated by treatment with N-bromoacetamide (NBA). Strychnine, applied to the cytoplasmic face of Na channels at concentrations ranging from 25 to 100
