1. Copolímeros anfifílicos constituídos de metacrilato de sacarose e monômeros acrílicos / Amphiphilic copolymers consisting of sucrose methacrylate and acrylic monomers
Neste trabalho foram sintetizados copolímeros anfifílicos constituídos de 1¿-O-metacrilato de sacarose (SMA) com os monômeros comerciais metacrilato de metila (MMA) ou N-isopropilacrilamida (NIPAAm), em diferentes composições molares. Catálise enzimática foi empregada para obtenção do monômero regioseletivamente monofuncional 1¿-O-metacrilato de

2. 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

3. Sucrose Compartmentation in the Palisade Parenchyma of Vicia faba L 1
Intracellular sucrose compartmentation in the palisade parenchyma of Vicia faba L. leaflets was investigated by comparing the specific radioactivity of photosynthetically labeled [14C]sucrose in samples enriched in vacuole to that in samples enriched in cytoplasm. Brief centrifugation of leaflet punches was used to sediment most of the palisade parenchyma cy

4. Artifacts in the Embedment of Water-soluble Compounds for Light Microscopy 12
The relative effectiveness of freeze-drying and freeze-substitution in accurately preserving the distribution of water-soluble compounds in plants tissues was evaluated. Specimens with a known distribution of water-soluble materials (sucrose-infiltrated pith blocks and red beet tissue) were freeze-dried or freeze-substituted and embedded in paraffin, Epon, o

5. Compartmentation in Vicia faba Leaves: I. Kinetics of 14C in the Tissues following Pulse Labeling 12
Leaflets of Vicia faba were pulse-labeled with 14CO2 to follow the subsequent movement of photosynthate between leaf tissues. Samples were taken during a 12CO2 chase, quick frozen, freeze-substituted, and embedded in methacrylate. Paradermal sections provided tissue samples consisting only of upper epidermis, palisade parenchyma, spongy parenchyma and veins,

6. Contact-dependent regulation of vinculin expression in cultured fibroblasts: a study with vinculin-specific cDNA probes.
Vinculin specific cDNA clones were isolated from chicken embryo fibroblast (CEF) cDNA library in lambda gt11. The clones, ranging in size from 2.8 to 5.0 kb, were initially selected by rabbit antibodies to vinculin. Their identity was further confirmed by their specific reactivities with a battery of different vinculin-specific monoclonal antibodies. Souther
