2. Floral Scent and Nectar Sugar Composition of Temnadenia odorifera (Apocynoideae, Apocynaceae)
Temnadenia odorifera is an endemic species from the Brazilian Atlantic Forest. This study was developed in order to identify the volatile compounds emitted by the living flowers and nectar, to evaluate the temporal pattern of scent emission, and the sugars composition of its nectar. Analyses of the flower scent by dynamic headspace in vivo, of nectar sugar c

4. Characterization of lyophilized liposomes produced with non-purified soy lecithin: a case study of casein hydrolysate microencapsulation
A commercial casein hydrolysate was microencapsulated in liposomes produced with non-purified soy lecithin, cryoprotected with two different disaccharides and lyophilized. The encapsulation efficiency of casein hydrolysate ranged from 30 to 40%. The powders were analyzed by differential scanning calorimetry (DSC), scanning electron micrography (SEM), infrare

5. Síntese e relação estrutura-toxicidade de derivados aminoglicosídeos como potenciais protótipos na busca de um fármaco seguro para o tratamento da Doença de Ménière / Synthesis and structure-toxicity relationship of aminoglycosides derivatives as a lead in the search for a selective drug for the treatment of Méniere disease.
Os aminoglicosídeos são antibióticos utilizados para o tratamento de muitas infecções bacterianas graves. A maioria é produzida por microorganismos (gêneros Streptomyces e Actinomyces), mas a semi-síntese resultam na descoberta de notáveis aminoglicosídeos. Apesar de seu mecanismo de ação seletivo, os aminoglicosídeos são extremamente tóxicos.

6. Análise de glicosaminoglicanos e proteoglicanos em linhagens tumorais de próstata / Analysis of glycosaminoglycans and proteoglycans in prostate cancer cell lines
Proteoglycans (PG) are cell surface, extracellular matrix and citoplasmatic granule macromolecules, that play an important role in cellcell and cell-matrix interactions. Several studies indicated that significant changes in PG content occur in the tumor stroma of epithelial neoplasms and that these alterations influence tumor growth and invasion. In this stu

7. Desenvolvimento e avaliaÃÃo da tecnologia de produÃÃo de Ãsteres homogÃneos de sacarÃdeos por acetilaÃÃo catalÃtica
As part of the systematic study of the process of acetylation of saccharides aiming to obtain products of industrial interests, we did tests with monosaccharides (glucose and fructose), disaccharides (sucrose). The sucrose composing abundant raw material deserves special attention as reagent acetylation of departure for a homogeneous environment. In the pres
