1. Previous spatial learning is required for the development of place preference in rats following chronic administration of and withdrawal from morphine
The positive reinforcing properties of addictive drugs have a primary role in the development of drug dependence. In the field of opiates, great attention has been given to this phenomenon, as well as to the negative properties eliciting craving and inducing relapse during withdrawal. This study was designed to evaluate whether elevated plus-maze (EPM) exper

2. Mapeamento e construÃÃo de um processo de aprendizagem baseado em competÃncias conversacionais para a realizaÃÃo da elicitaÃÃo de requisitos
The main problem observed by researches and reports with softwareâs engineering is the inadequate approach that the developers and users have been used during the project. This process frequently happen in the beginning of the construction of requirement eliciting, consequence of the conversations. Because conversations is the more natural and common activi

3. A pratica de desenvolvimento de software e a arbordagem da semiotica organizacional
We have experienced, in the enterprise world, an evolution in the forms of software development, demanding for shorter cycles, and new methods and technologies are appearing continuously. The user of information systems, each time more involved with informatics, imposes requirements relating to the quality and the reduction of the software development cyc1e.

4. Abscisic Acid Structure-Activity Relationships in Barley Aleurone Layers and Protoplasts (Biological Activity of Optically Active, Oxygenated Abscisic Acid Analogs).
Optically active forms of abscisic acid (ABA) and their oxygenated metabolites were tested for their biological activity by examining the effects of the compounds on the reversal of gibberellic acid-induced [alpha]-amylase activity in barley (Hordeum vulgare cv Himalaya) aleurone layers and the induction of gene expression in barley aleurone protoplasts tran

5. Selective expansion of high- or low-avidity cytotoxic T lymphocytes and efficacy for adoptive immunotherapy.
The conventional approach to cytotoxic T-lymphocyte (CTL) induction uses maximal antigen concentration with the intent of eliciting more CTL. However, the efficacy of this approach has not been systematically explored with regard to the quality of the CTLs elicited or their in vivo functionality. Here, we show that a diametrically opposite approach elicits C

6. Involvement of Mouse Rev3 in Tolerance of Endogenous and Exogenous DNA Damage
The Rev3 gene of Saccharomyces cerevisiae encodes the catalytic subunit of DNA polymerase ζ that is implicated in mutagenic translesion synthesis of damaged DNA. To investigate the function of its mouse homologue, we have generated mouse embryonic stem cells and mice carrying a targeted disruption of Rev3. Although some strain-dependent variation was observ

7. Purification of a Trypanosoma cruzi membrane glycoprotein which elicits lytic antibodies.
Recent studies on the humoral immune response to Trypanosoma cruzi have shown that antibodies which are able to bind living parasites and lyse them in conjunction with complement are associated with host protection. Antibodies which support complement-mediated lysis (CML) of trypomastigotes are elicited as a result of an active infection and not after immuni

8. Cooperative interactions in the induction of long-term potentiation and depression of synaptic excitation between hippocampal CA3-CA1 cell pairs in vitro.
The requirement for cooperative interactions between multiple synaptic inputs in the induction of long-term potentiation (LTP) and long-term depression (LTD) has been tested at Schaffer collateral synapses with paired recordings from monosynaptically coupled CA3-CA1 cell pairs in rat hippocampal slice cultures. Tetanization of single presynaptic neurons at 5

9. Control of Dimorphism in Mucor by Hexoses: Inhibition of Hyphal Morphogenesis
In anaerobic cultures of Mucor rouxii, morphogenesis was strongly dependent on hexose concentration as well as pCO2. At low levels of hexose or CO2, or both, hyphal development occurred; at high levels, the fungus developed as yeast cells. Other dimorphic strains of Mucor responded similarly to hexose and CO2 but differred in their relative sensitivity to th

10. Moderate immunodeficiency does not increase susceptibility to Salmonella typhimurium aroA live vaccines in mice.
Salmonellae carrying appropriate mutations in genes of the aromatic biosynthesis pathway are effective as live vaccines in animals, and they are candidate typhoid vaccines for human use. They are also very effective as carriers of recombinant antigens from other pathogens to the immune system, eliciting circulatory, secretory, and cell-mediated immunity to f
