13. SobrevivÃncia e crescimento larval do camarÃo marinho Litopenaeus vannamei alimentado com o copÃpodo bentÃnico Tisbe biminiensis
The production of Artemia cysts not always reaches the increasing demand of aquaculture. Thus, alternative diets need to be tested. The first objective was to investigate the effect of different concentration of Tisbe biminiensis copepod offspring in the ingestion rate of Litopenaeus vannamei larvae and to estimate the best concentration to feed them. The se

14. Análise de sistemas de secagem de café utilizando-se bomba de calor e gás liqüefeito de petróleo - GLP / Analysis of systems of coffee drying being used heat pump and liquefied gas of petroleum - LGP
Objetivou-se com este trabalho analisar a secagem de café cereja descascado e desmucilado em secador de café em lotes intermitentes de fluxos concorrentes, utilizando uma bomba de calor para condicionar o ar de secagem. Na avaliação da viabilidade técnica e do custo operacional deste sistema, fez-se um estudo comparativo com o sistema de secagem para ca

15. In vitro study of the fit of cast post and core, obtained from different acrylic resin patterns / Estudo in vitro da adaptação de retentores intra-radiculares fundidos, modelados com diferentes resinas acrílicas autopolimerizáveis
Endodontically treated teeth are often mutilated by caries and access requirements. The remaining structure requires special treatment to prevent further destruction. When a large portion of the clinical crown has been lost, it is often impossible to achieve sufficient anchorage of a restoration in the remaining dentin. In such situations, a root-canal-retai

16. High affinity nucleic acid aptamers for streptavidin incorporated into bi-specific capture ligands
We have isolated 2′-Fluoro-substituted RNA aptamers that bind to streptavidin (SA) with an affinity around 7 ± 1.8 nM, comparable with that of recently described peptide aptamers. Binding to SA was not prevented by prior saturation with biotin, enabling nucleic acid aptamers to form useful ternary complexes. Mutagenesis, secondary structure analysis, ribo

17. Human immune response against outer membrane proteins of Moraxella (Branhamella) catarrhalis determined by immunoblotting and enzyme immunoassay.
The role of Moraxella (Branhamella) catarrhalis as a respiratory tract pathogen is increasingly recognized. We looked at the human immune response against individual outer membrane proteins of M. catarrhalis and against the 81-kDa CopB protein, which has previously been shown to be a target for protective antibodies. Paired serum samples from six elderly pat

18. Etioplast differentiation in arabidopsis: both PORA and PORB restore the prolamellar body and photoactive protochlorophyllide-F655 to the cop1 photomorphogenic mutant.
The etioplast plastid type of dark-grown angiosperms is defined by the accumulation of the chlorophyll (Chl) precursor protochlorophyllide (Pchlide) and the presence of the paracrystalline prolamellar body (PLB) membrane. Both features correlate with the presence of NADPH:Pchlide oxidoreductase (POR), a light-dependent enzyme that reduces photoactive Pchlide

19. Lack of effect of peritubular protein on passive NaCl transport in the rabbit proximal tubule.
The effect of peritubular protein removal on passive NaCl transport was examined in the isolated rabbit proximal convoluted tubule (PCT). Three modes of passive NaCl transport were tested: (a) paracellular backflux of NaCl, (b) convective flow of NaCl through junctional complexes, and (c) anion gradient-dependent NaCl transport. The effect of peritubular pro
