Desempenho de genótipos de soja-hortaliça de ciclo precoce [Glycine max (L.) Merril] em diferentes densidades

Objetivando-se avaliar o desempenho de dois genótipos de soja-hortaliça de ciclo precoce [Glycine max (L.) Merril], em diferentes densidades, foi instalado um ensaio, em área experimental do Setor de Olericultura e Plantas Aromático-Medicinais, pertencente ao Departamento de Produção Vegetal, nas dependências da Faculdade de Ciências Agrárias e Veterinárias (FCAV-UNESP), Campus de Jaboticabal-SP. O delineamento experimental foi o de parcelas subdivididas, adotando-se nas parcelas os genótipos e nas subparcelas as densidades, com quatro repetições por tratamento. Cada parcela experimental foi constituída por quatro linhas de 4,5m de plantio, com densidades de 20, 10 e 7 plantas por metro e 0,60m nas entrelinhas, sendo consideradas para avaliação 20 plantas por parcela, das duas linhas centrais. As sementes foram semeadas em bandejas de poliestireno expandido de 128 células, contendo substrato Plantmax Hortaliças®. O transplantio ocorreu dez dias após a semeadura, em solo devidamente preparado, conforme recomendações para a cultura. A colheita foi realizada quando os legumes estavam em estádio reprodutivo R6. Avaliaram-se os genótipos JLM010 e CNPSOI quanto às características: número médio de legumes por planta, número médio de sementes por legume, massa fresca de 100 sementes e produtividade estimada de grãos imaturos. Com base nos resultados obtidos concluiu-se que o genótipo JLM010 é o mais recomendado e deve ser plantado na densidade de 7 plantas por metro.

Desempenho em leitura e escrita de escolares com transtorno fonológico

O transtorno fonológico ocorre quando há dificuldade quanto à aquisição e uso dos sons da fala. O objetivo deste estudo foi caracterizar o desempenho em leitura e escrita de escolares com transtorno fonológico. Participaram do estudo 28 escolares na faixa etária de 7 a 9 anos de idade com trocas na fala. A amostra foi composta de 70% do sexo masculino e 30% do feminino. Os resultados revelaram que entre 57% e 85% dos escolares da 1 a à 3 a séries apresentaram transtorno fonológico presente na oralidade e na escrita, enquanto que 100% dos escolares da 4 a série apresentaram transtorno fonológico evidenciado apenas na leitura e na escrita. Os achados deste estudo demonstraram que a linguagem oral está intrinsecamente relacionada com o desenvolvimento da leitura e da escrita e que alterações no processamento fonológico da criança podem desencadear alterações no desenvolvimento da leitura e escrita.

A comunicação midiática da tecnociência: uma leitura a partir do enfoque cts

This paper has two basic aims. The first one is to propose a discussion about the journalistic potential of information regarding patents, trying to identify using some experiences, the characteristics of this techno-scientific product that, somehow, draws the attention of the media. The second one is to understand the relationship between media and patents from the perspective of the studies on Science, Technology and Society (STS). The following assumption is made: the media treatment of patents is still strongly marked by economic bias and follows the logic of the supply-linear model, under which, among other important ideas, basic research is followed by applied research and, then, by technological developments that allow the launch of a new product bringing benefits for society. The paper presents results from case studies of science communication involving patents of the Federal University of Silo Carlos (UFSCar), Brazil, indicating that they are an important source of news for the media, and emphasizing the importance of the media in the national and international discussions about the protection of intellectual work.

Modelos lineares generalizados mistos na avaliação genética da prenhez precoce na raça Nelore

This study aimed to use the generalized linear models with probit and logit link function to evaluate early pregnancy, and to observe the effects on genetic variability and on sire selection when different ages are adopted in the definition of this trait. Early pregnancy was studied at 15 (EP15), and 21 (EP21) months. The analysis was done in R software. Pearson correlations (PC), between genetic predicted values and percentage of bulls in common considering only 10% of bulls with higher genetic values (TOP 10), between classification by logit and probit models and in each model among EP15 and EP21, were calculated. The heritability for EP15 and EP21 were close between models, except for EP15 using probit link function. PC and TOP10 among models were high. The Akaike and Bayesian criteria reported was similar between models. TOP10, considering the same model, among EP15-EP21 were moderated between EP15-EP21.

Utilização do metabolismo protéico ( 15N-glicina) na detecção precoce de agravamento da atividade da doença em pacientes portadores de retocolite ulcerativa inespecífica

Disease activity was assessed in 10 (five males and five females) ulcerative colitis patients through the following parameters: clinical, laboratory, sigmoidoscopic and histological. Protein metabolism was also assessed with 15N-glycine and urinary ammonia as end product. Only one patient had exacerbation of the disease two months after the study started. This patient presented in the beginning of the study protein synthesis and breakdown of 4.51 and 3.47 g protein/kg/day, respectively, values higher than all other patients, showing an hypermetabolic state, suggesting an increase of the disease activity. However, this increase was not detected by others indicators and indexes utilised. These data allow to suggest the hypothesis that protein metabolism predicts precociously the exacerbation of disease activity in ulcerative colitis patients.

Desempenho de escolares com distúrbio específico de leitura em programa de remediação.

BACKGROUND: Specific reading disability is caused by disruptions in the language abilities. AIM: To characterize the neurological, cognitive and phonological performances of scholars with specific reading disabilities pre and post a remediation program. METHOD: Group I consisted of ten scholars with specific reading disability who did not undergo the remediation program. Group II consisted of ten scholars with specific reading disabilities who took part in the proposed program. Neurological, psychological and phonological evaluations were made, as well as a test of scholastic performance and of reading and writing before and after the program. RESULTS: The scholars who underwent the remediation program demonstrated improvements in their neurological and cognitive performances and also in the processing of phonological information. CONCLUSION: Favoring of the emergence of phonological and syntactic awareness after the remediation program.

A administração precoce de hormônio de crescimento resulta em efeitos deletérios na remodelação ventricular após o infarto agudo do miocárdio

Objective: To assess the effect of growth hormone (GH) on myocardial remodeling in infarcted rats. Methods: This study comprised 24 Wistar rats divided into 3 groups as follows: 1) AMI-GH group - comprising 8 rats that underwent infarction and were treated with GH; 2) AMI group - comprising 8 rats that underwent infarction and received only the diluent of the GH solution; and 3) control group (C group) - comprising 8 rats that underwent simulated infarction. After 30 days, the animals underwent functional study through echocardiography, and the changes in myocardial contractility of the isolated left ventricular (LV) papillary muscle were studied. Results: The echocardiography identified an increase in the diastolic (C=7.32±0.49; AMI=8.50±0.73; AMI-GH=9.34±0.73; P<0.05) and systolic (C=3.38±0.47, AMI=5.16±1.24; AMI-GH=5.96±1.54; P<0.05) diameters (mm) in the LV of the infarcted animals. The AMI-GH group animals had a lower ejection fraction (%) (C=0.9±0.03; AMI=0.76±0.12; AMI-GH=0.72± 0.14; P<0.05 for C vs AMI-GH) compared with those in controls. The study of the isolated left ventricular papillary muscle showed that the AMI-GH group had changes (C=1.50±0.59; AMI= 1.28±0.38; AMI-GH=1.98±0.41; P<0.05 for C vs AMI-GH) only in the tension at rest (TR - g/mm2) and in the time delta for a 50% decrease in the tension developed (TR50, ms) after stimulation with calcium (C=23.75±9.16; AMI=-16.56±14.82; AMI-GH=-4.69±8.39; P<0.05 for C vs AMI-GH) and in the delta of tension developed (TD, g/mm2) after stimulation with isoproterenol (C=0.99±0.17; AMI=0.54±0.62; AMI-GH=0.08±0.75; P<0.05 for C vs AMI-GH) compared with those in control animals. Conclusion: The early administration of GH in the experimental infarction model in rats may result in adverse effects on the process of ventricular remodeling.

Uma leitura de 26 poetas hoje

This reading presents a sample from this anthology and tries to identify in it the faces of resistence indicated by Alfredo Bosi in his essay: Poesia Resistência. ln the several manners the poets of different generations chose for their personal cry of alert we find a poetry wich is spontaneous, authentic and, above all, resistent. This is due mainly to the renewal of the poetical expression, impregnated with affectiveness and intimism, which included colloquial language and the devices used by all great Brazilian poetry since the Modernism of 1922.

Determinação precoce do sexo fetal pela análise do DNA no plasma materno

Purpose: to verify the viability of early diagnosis of fetal gender in maternal plasma by the real-time polymerase chain reaction (real-time PCR) starting at the 5th week of pregnancy. Methods: peripheral blood was collected from pregnant women with single fetus starting at the 5th week of gestation. After centrifugation, 0.4 mL plasma was separated for fetal DNA extraction. The DNA was analyzed in duplicate by real-time PCR for two genomic regions, one of the Y chromosome and the other common to both sexes, through the TaqMan® method, which uses a pair of primers and a fluorescent probe. Patients who aborted were excluded. Results: a total of 79 determinations of fetal DNA in maternal plasma were performed in 52 pregnant women. The results of the determinations were compared to fetal gender after delivery. Accuracy according to gestational age was 92.6% (25 of 27 cases) at 5 weeks with 87% sensitivity, and 95.6% (22 of 23 cases) at 6 weeks with 92% sensitivity. Starting at the 7th week of pregnancy, accuracy was 100% (29 of 29 cases). Specificity was 100% regardless of gestational age. Conclusion: real-time PCR for the detection of fetal gender in maternal plasma starting at the 5th week of gestation has good sensitivity and excellent specificity. There was agreement of the results in 100% of the cases in which male gender was diagnosed, regardless of gestational age, and from the 7th week of gestation for female gender diagnosis.

Desempenho em consciência fonológica, memória operacional, leitura e escrita na dislexia familial

Background: familial dyslexia. Aim: to characterize and compare the phonological awareness, working memory, reading and writing abilities of individuals whose family members are also affected. Method: in this study 10 familial nuclei of natural family relationship of individuals with dyslexia were analyzed. Families of natural individuals living in the west region of the state of São Paulo were selected. Inclusion criteria were: to be a native speaker of the Brazilian Portuguese language, to have 8 years of age or more, to present positive familial history for learning disabilities, That is, to present at least one relative with difficulties in learning. Exclusion criteria were: to present any neurological disorder genetically caused or not, in any of the family members, such as dystonia, extra pyramidal diseases, mental disorder, epilepsy, attention deficit and hyperactivity disorder (ADHA); psychiatric symptoms or conditions; or any other pertinent conditions that could cause errors in the diagnosis. As for the diagnosis of developmental dyslexia, information about the familial history of the adolescents and children was gathered with the parents, so that a detailed pedigree could be delineated. Neurological, psychological, speech-language, and school performance evaluations were made with the individuals and their families. Results: the results of this study suggest that the dyslexic individuals and their respective relatives, also with dyslexia, presented lower performances than the control group in terms of rapid automatic naming, reading, writing and phonological awareness. Conclusion: deficits in phonological awareness, working memory, reading and writing seem to have genetic susceptibility that possibly determine, when in interaction with the environment, the manifestation of dyslexia.

Música como aia da vontade: ensaio sobre a leitura wagneriana de Schopenhauer

In the year 1851, Richard Wagner had his first contact with the philosophy of Schopenhauer, a fact that was followed soon by his proclaimed and somewhat surprising conversion to schopenhauerianism. Tweny years later, his debt to Schopenhauer is reaffirmed in Beethoven, a comemorative writing in which are to be found the outlines of a philosophy of music - claimed by the composer to be based on Schopenhauer's aesthetics - that had great influence in Nietzsche's theoretical elaboration of the dionysiac, as it appears in The birth of Tragedy. My work aims primarily at investigating to what extent the musical aesthetics outlined in Beethoven is actually compatible with that presented in The world as Will and representation. The pointing out of remarkable differences between the two aesthetic conceptions gives then rise to some reflexions concerning the character of the relations between Wagner, Schopenhauer and the young Nietzsche.
