Attention, memory and verbal learning and their relation to schizotypal traits in unaffected parents of schizophrenic patients

The main objective of this ex post facto study is to compare the differencesin cognitive functions and their relation to schizotypal personality traits between agroup of unaffected parents of schizophrenic patients and a control group. A total of 52unaffected biological parents of schizophrenic patients and 52 unaffected parents ofunaffected subjects were assessed in measures of attention (Continuous PerformanceTest- Identical Pairs Version, CPT-IP), memory and verbal learning (California VerbalLearning Test, CVLT) as well as schizotypal personality traits (Oxford-Liverpool Inventoryof Feelings and Experiences, O-LIFE). The parents of the patients with schizophreniadiffer from the parents of the control group in omission errors on the ContinuousPerformance Test- Identical Pairs, on a measure of recall and on two contrast measuresof the California Verbal Learning Test. The associations between neuropsychologicalvariables and schizotpyal traits are of a low magnitude. There is no defined pattern ofthe relationship between cognitive measures and schizotypal traits

Functional complementation of Leishmania (Leishmania) amazonensis AP endonuclease gene (lamap) in Escherichia coli mutant strains challenged with DNA damage agents

During its life cycle Leishmania spp. face several stress conditions that can cause DNA damages. Base Excision Repair plays an important role in DNA maintenance and it is one of the most conserved mechanisms in all living organisms. DNA repair in trypanosomatids has been reported only for Old World Leishmania species. Here the AP endonuclease from Leishmania (L.) amazonensis was cloned, expressed in Escherichia coli mutants defective on the DNA repair machinery, that were submitted to different stress conditions, showing ability to survive in comparison to the triple null mutant parental strain BW535. Phylogenetic and multiple sequence analyses also confirmed that LAMAP belongs to the AP endonuclease class of proteins.

Influências do comportamento comunicativo não-verbal do docente em sala de aula: visão dos docentes de enfermagem

Na interação professor-aluno, o professor tem um importante papel e seu bom desempenho depende da consciência e habilidade que tenha na comunicação. Este trabalho teve como objetivo verificar junto aos docentes de Enfermagem, o conhecimento e a importância atribuída aos sinais não-verbais na sua interação em sala de aula. É um estudo exploratório, na linha qualitativa e foram entrevistados 25 docentes da EEUSP, de outubro a dezembro de 1999. Dentre os achados, pudemos verificar que são considerados facilitadores da interação: algumas características do professor, características do aluno, a regularidade de contato, o tipo de conteúdo exposto e a própria comunicação.

A auto-estima e o não-verbal dos pacientes com queimaduras

Esta pesquisa teve como objetivos identificar o grau de auto-estima dos pacientes do Ambulatório de Seqüelas de Queimaduras do HC-FMUSP e identificar os sinais não-verbais emitidos pelos pacientes, quando questionados sobre sua auto-estima. Realizado com 80 pacientes (54 mulheres e 26 homens) atendidos na unidade durante o mês de fevereiro de 2002, o projeto foi aprovado pelas Comissões de Ética em Pesquisa da EEUSP e do HC-FMUSP e as entrevistas individuais com os pacientes baseadas em uma escala para avaliação de auto-estima validada no Brasil e na classificação de sinais não-verbais proposta por Silva. Dentre os resultados, verificamos que 18,75% pacientes apresentam baixa auto-estima, 32,50% média auto-estima e 48,75% pacientes alta auto-estima. O complemento foi a função dos sinais não-verbais mais freqüente entre os pacientes.

Choice of an adequate promoter for efficient complementation in Saccharomyces cerevisiae: a case study.

Conservation of the function of open reading frames recently identified in fungal genome projects can be assessed by complementation of deletion mutants of putative Saccharomyces cerevisiae orthologs. A parallel complementation assay expressing the homologous wild type S. cerevisiae gene is generally performed as a positive control. However, we and others have found that failure of complementation can occur in this case. We investigated the specific cases of S. cerevisiae TBF1 and TIM54 essential genes. Heterologous complementation with Candida glabrata TBF1 or TIM54 gene was successful using the constitutive promoters TDH3 and TEF. In contrast, homologous complementation with S. cerevisiae TBF1 or TIM54 genes failed using these promoters, and was successful only using the natural promoters of these genes. The reduced growth rate of S. cerevisiae complemented with C. glabrata TBF1 or TIM54 suggested a diminished functionality of the heterologous proteins compared to the homologous proteins. The requirement of the homologous gene for the natural promoter was alleviated for TBF1 when complementation was assayed in the absence of sporulation and germination, and for TIM54 when two regions of the protein presumably responsible for a unique translocation pathway of the TIM54 protein into the mitochondrial membrane were deleted. Our results demonstrate that the use of different promoters may prove necessary to obtain successful complementation, with use of the natural promoter being the best approach for homologous complementation.

A comunicação não-verbal enquanto fator iatrogênico

O estudo teve como objetivo verificar se os enfermeiros identificam situações nas quais os aspectos não-verbais da comunicação interpessoal entre profissionais de saúde e pacientes constituem fator iatrogênico. Os dados foram coletados por meio de entrevista semi-estruturada com oito enfermeiros e analisados segundo a metodologia de análise de conteúdo. Do discurso dos profissionais emergiram três categorias, que evidenciam a percepção da iatrogenia, suas conseqüências e características e a interrelação entre a linguagem não-verbal e o cuidado.

Definitional verbal patterns for semantic relation extraction

In this paper we present a description of the role of definitional verbal patterns for the extraction of semantic relations. Several studies show that semantic relations can be extracted from analytic definitions contained in machine-readable dictionaries (MRDs). In addition, definitions found in specialised texts are a good starting point to search for different types of definitions where other semantic relations occur. The extraction of definitional knowledge from specialised corpora represents another interesting approach for the extraction of semantic relations. Here, we present a descriptive analysis of definitional verbal patterns in Spanish and the first steps towards the development of a system for the automatic extraction of definitional knowledge.
