Instituições universitárias e produção do conhecimento

A produção do conhecimento em universidades é analisada como resultante da experiência individual em contexto histórico e sociocultural. Há fatores determinantes, de base epistemológica, e outros, condicionantes, na produção do conhecimento. Esta passa a adquirir significado estratégico para o país, inserido em uma economia globalizada. A aquisição de competitividade pelas nossas universidades dependerá de formas inovadoras de gestão de talentos.

Prevalência de Cryptosporidium sp. em cães de instituições da cidade de São Paulo

Objective Dogs play an important role as infection source of human cryptosporidiosis. The objective of the study was to determine the prevalence of Cryptosporidium sp. in dogs as well as to compare two techniques of fecal analysis.Methods Four-hundred and fifty canine fecal samples from the city of São Paulo were analyzed between 2003 and 2004. Fecal samples were randomly selected from dogs housed in a university veterinary hospital (group 1, n=200) and private kennels (group 2, n=250). The detection of Cryptosporidium was performed using modified Ziehl-Neelsen staining and Polymerase Chain Reaction (PCR) technique. Statistical analysis was performed using the two-tailed test of significance at 5% confidence interval (z critical=+/- 1.645).Results Only Cryptosporidium parvum oocysts were found the prevalences found by light microscopy examination and PCR techniques were 8.8% and 9.5%, respectively. Young animals showed a lower frequency (5.5%) compared to adults (10.1%). There was no statistically significant difference in Cryptosporidium prevalence between males and females.Conclusions the prevalence of C. parvum in the canine population studied was similar to that one found in the literature and affects equally males and females. The use of PCR allowed the detection of more positive cases than light microscopy.

Respostas do sorgo sacarino a N, P e K. II. Características tecnológicas

Foram conduzidos ensaios de campo utilizando-se duas cultivares de sorgo sacarino (Brandes e Rio) cultivadas em dois solos (Latossolo Roxo e Latossolo Vermelho-Escuro textura média), para estudo dos efeitos da aplicação de N, P e K sobre a produção de açúcar e de álcool. Foram avaliados os efeitos das adubações nos teores de sacarose, açúcares redutores, brix, fibra, e produção de álcool do sorgo sacarino. Os ensaios foram conduzidos no município de Barra Bonita, Estado de São Paulo. Com relação à produção de álcool por hectare, a cultivar Brandes respondeu positivamente ao N no LR e ao N e K no LEm, ao passo que a cultivar Rio não apresentou respostas significativas às adubações. As produções de álcool foram explicadas principalmente pelas produções de colmos, o que demonstra ser a produção de álcool por área uma função principalmente da quantidade de caldo produzido, desde que a cultivar apresente características tecnológicas dentro de um limite razoável. Considerando-se os locais e cultivares diferentes, os efeitos das adubações sobre os teores de sacarose, açúcares redutores e brix foram inconsistentes.

Características agronômicas e tecnológicas de genótipos de feijão do grupo comercial Carioca

Cultivars with high yield, adaptability and desirable technological characteristics are a must. The objective of this work was to evaluate agronomic and technologic characters of common bean genotypes from carioca commercial group. Genotypes were cultivated in water growing season, in 2001 and 2002. The experimental design was by randomized blocks with 29 genotypes and four replications. The IAC-Carioca, FT-Bonito, Rudá, Porto Real, CNFC 8008, CNFC 8011, CNFC 8012, CNFC 8013 and CNFC 8156 genotypes yielded above the average. The genotypes IAC-Carioca, CNFC 8012 and CNFC 8156 presented the best results with 3,000 kg ha-1 and 20 minutes cooking time.

Epidemiologia das dermatofitoses em instituições públicas da região de Araraquara - SP

Dermatophytosis on skin, hair and nails are the most common infectious process in the world. A total of 94 individuals from Public Institutions from the city of Araraquara - Sao Paulo/Brazil, with suspected of dermatophytic lesions were examined in order to determine the incidence and etiology of dermatophytosis. 105 specimens were collected from August to December of 2001 in the Mycology Laboratory of the Faculdade de Ciências Farmacêuticas. It was observed that 47 samples were positive for dermatophytes. Trichophyton rubrum was the prevalent specie (59.6%), followed by Microsporum canis (17%), T. tonsurans (10.6%), T. mentagrophytes (8.5%) and Epidermophyton floccosum (4.3%). T. rubrum was the most frequent in interdigital lesions (81.5%) and M. canis was the main dermatophyte involved in scalp lesions (58.3%). Therefore, it was observed a predominance of antropophilic and zoophilic species, respectively. These results are in agreement with statistical data from South and Southeast regions of Brazil, as well as from other parts of the world in which these fungi were the most frequently isolates from tinea pedis and tinea capitis. In this study, it was also observed a high percentage of T. tonsurans (41.7%) in tinea capitis and this result was different from the statistical data collected until now in our region.

Caracterização e análise do estado mental e funcional de idosos institucionalizados em instituições públicas de longa permanência

Background: This study had as objective to characterize the institutionalized elderly residents in three long-term care facilities, about their functional capacity and mental state, and to evaluate if there is a correlation between both. Methods: To do so, three instruments were used: an identification form, the Mini-Mental State Examination (MMSE) and Barthel's Index. For statistical analysis the Person's Correlation and ANOVA Test were used. Results: The population studied consisted of 115 elders with ages between 62 and 104 years old, 40.66% females and 59.13% males. 49.56% are literate and 50.43% illiterate. Regarding the marital status, singles (46.65%) and widows (21.8%) were predominant. About the mental and functional state, there was a high rate of elders showing cognitive decline (76.72%) and functionally independent (75.65%). Conclusions: According to the results, one can notice that there is a mild degree of correlation between the Barthel's Index and MMSE (r = 0.441; p < 0.000), and the variables of gender and age are not influenced in the results of these instruments. There is a significant statistical relation (p < 0.0001) between education and mental and/or functional state of the individual.

Propagandas de medicamentos psicoativos: Análise das informações científicas

Objective: According to the World Health Organization, medicinal drug promotion should be reliable, accurate, truthful, informative, balanced, up-to-date and capable of substantiation. The objective of the present study was to review psychoactive drug advertisements to physicians as for information consistency with the related references and accessibility of the cited references. Methods: Data was collected in the city of Araraquara, Southeastern Brazil, in 2005. There were collected and reviewed 152 drug advertisements, a total of 304 references. References were requested directly from pharmaceutical companies' customer services and searched in UNESP (Ibict, Athenas) and BIREME (SciELO, PubMed, free-access indexed journals) library network and CAPES journals. Advertisement statements were checked against references using content analysis. Results: Of all references cited in the advertisements studied, 66.7% were accessed. Of 639 promotional statements identified, 346 (54%) were analyzed. The analysis showed that 67.7% of promotional statements in the advertisements were consistent with their references, while the remaining was either partially consistent or inconsistent. Of the material analyzed, an average 2.5 (1-28) references was cited per advertisement. In the text body, there were identified 639 pieces of information clearly associated with at least one cited reference (average 3.5 pieces of information per advertisement). Conclusion: The study results evidenced difficult access to the references. Messages on efficacy, safety and cost, among others, are not always supported by scientific studies. There is a need for regulation changes and effective monitoring of drug promotional materials.
