Coexistencia de variantes HIV-1 com insercao dipeptidica no gene da transcriptase reversa

O objetivo desta comunicação foi descrever a detecção de coexistência de variantes HIV-1 com inserções de dois aminoácidos entre os códons 69 e 70 da transcriptase reversa. Tais variantes foram isoladas de paciente do sexo masculino, 16 anos de idade, em tratamento no interior do estado de São Paulo. Após confirmação de falha terapêutica, foi realizado teste de resistência a antirretrovirais, a partir do qual foram detectadas duas variantes contendo inserções dos aminoácidos Ser-Gly/Ser-Ala no códon 69 da transcriptase reversa, além da mutação T69S. Tais inserções possuem baixa prevalência, não foram relatadas em caráter de coexistência no Brasil e estão relacionadas com a resistência a múltiplas drogas, tornando o achado relevante do ponto de vista epidemiológico.

Emprego e trabalho no início do século XXI: revisitando Keynes e Marx

The nature of labor in advanced economies has presented a significant change lately. The technological process has resulted in the reduction of labor without content and the expansion of labor with higher qualification or schooling, a phenomenon that can be discussed by turning to Keynes and Marx. As far as Keynes is concerned, his foresight was that technological progress would generate a huge reduction of labor time and the expansion of leisure time. Since this did not occur, the failure may be attributed to the fact of having worked with opposition between labor without content and leisure. Thus, it was not possible to capture the historical changes in labor and man's relationship with it. Marx's viewpoint is completely different, because his opposition takes place between labor without content and activity labor, the latter impregnated with content and essential to the development of individualities. Therefore, present reality has a greater identification with Marx and presents major challenges to capitalism and its critique.

Achados timpanométricos em um grupo de escolares

PURPOSE: to characterize and compare the tympanometric findings in a group of preschoolers. METHOD: 112 preschoolers were evaluated, both genders, aged from four years old to five years and eleven months old who attended a Municipal School of Early Childhood Education in the suburbs of Marilia city- SP. Tympanometry was used as triage procedure. It was considered that the child PASSED in the triage when it presented an A type tympanometric curve, bilaterally, being reevaluated in case of failure. RESULTS: it was observed a high failure index (63.4%) in the studied population. The older female preschoolers presented a higher index of A type tympanograms, in both ears. There was a higher incidence of failure in male preschoolers aged from four years to four years and eleven months. CONCLUSION: in this sample, there was a high index of tympanometric alteration. There was a tendency among younger male students to present a higher index of tympanometric alteration when compared to older female preschoolers, this difference was not statistically significant.

Molecular characterization of accessions of crabgrass (Digitaria nuda) and response to ametryn

Digitaria species are sugar cane crop weeds in Brazil and are being controlled with herbicides, although there are some reports of control failure, notably to the triazine group. Molecular techniques are recommended to analyze the genetic variability in weeds. RAPD (Random Amplified Polymorphic DNA), PCR-RFLP (Polymerase Chain Reaction - Restriction Fragment Length Polymorphism) and, in combination with sequencing, allow the localization of resistance genes, as well as possible mutations related to the onset of resistant individuals in some species. Thus, the objective of this work was to characterize ten accessions of Digitaria spp. by RAPD and PCR-RFLP markers, to sequence a conserved region of the psbA gene and evaluate the accessions response to ametryn. As showed by molecular analysis there was high genetic similarity among the accessions, all of them presented similar genetics profiles and were susceptible to ametryn.

Desempenho de escolares com dislexia e transtorno do déficit de atenção e hiperatividade nos processos de leitura

This study aimed to characterize and to compare the performance of students with an interdisciplinary diagnosis of dyslexia and attention deficit hyperactivity disorder (ADHD) in students with good academic performance on the reading processes. Sixty students from both genders, from 2nd to 4th grades of municipal public schools in Marília - SP participated in this study, they were distributed as follows: GI, 20 students with interdisciplinary diagnosis of dyslexia; GII, 20 students with ADHD and GIII, 20 students with good academic performance, paired according to gender, age and grade level with GI and GII. The students were submitted to the application of the assessment of reading processes (PROLEC) composed by four processes: letters identification, lexical, syntactical and semantic. The results highlighted that the students of GIII showed superior performance comparing with GI and GII. There was difference between GI and GII only in low frequency word reading and non words reading of the lexical process. The inferior performance from GI and GII in the PROLEC tests can be justified by the difficulty on the coding and decoding abilities. In ADHD students this difficulty was due to impaired interaction between the visual, linguistic, attention and auditory processing and in the dyslexic students was due to failure at the phonological mediation process, which depends on the knowledge of rules of grapheme - phoneme conversion to the acquisition of word reading. These changes affect the reading achievement and the comprehension of the read text.
