O impacto do Método Mãe Canguru no processo de aprendizagem de prematuros de baixo peso: Revisão da literatura

Technology advances and scientific studies in Neonatal Intensive Care Units (NICU) have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB). However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC) were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011), that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL), a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

Exposição neonatal a drogas ototóxicas e possíveis alterações auditivas

Introduction: Scientific evidence indicates that neonatal exposure to ototoxic drugs cause hearing loss in newborns. Objective: To characterize the use of ototoxic antibiotics in newborns (NB), treated in the Neonatal Intensive Care Unit (NICU) and evaluate possible hearing modifications. Methods: A descriptive cross-sectional quantitative approach, using data from medical records of infants who were at some time in the NICU and used antibiotics, including ototoxic, from January to June 2004 as much as 2010, and the data were compared and analyzed. Parents/guardians of infants born in 2004 were contacted and applied a questionnaire containing questions about the children’s hearing. These children were submitted to audiological evaluation. Results: There was significant reduction in the time of use, the amount of antibiotics prescribed to newborns and Vancomycin prescription in 2010 compared to 2004. The hearing tests of 13 born in 2004 showed: sensorineural hearing loss in only 2 (one with moderate hearing loss and descending configuration in pure tone audiometry and the other with bilateral cochlear impairment); audiometric thresholds within the normal range in 11 patients, and the presence of otoacoustic emissions in 9. In Evoked Auditory Brainstem Response (ABR) no changes were observed. Conclusion: The reduction in the time of use, the amount and types of antibiotics observed may be related to the adoption of a Protocol in 2008, by the service. In contrast, auditory alterations may be related to a neonatal exposure to antibiotics in 2004.

Busca de parceiros físicos das proteínas ADAM23 e MX1, utilizando o sistema de duplo híbrido em Saccharomyces cerevisae

A metilação de ilhas CpG em regiões regulatórias de vários genes tem sido descrita como um processo importante no silenciamento de genes supressores de tumor e diretamente envolvida no processo de carcinogênese de uma série de tumores. O estudo desses genes afetados pela metilação em tumores visa identificar possíveis marcadores moleculares para o diagnóstico, prognóstico e tratamento de tumores, além de possibilitar a descoberta de fatores importantes no processo biológico do câncer. Os genes MX1 e ADAM23 foram identificados como diferencialmente metilados em linhagens celulares provenientes de carcinoma de cabeça e pescoço. Neste sentido, ao estudar o perfil diferencial de metilação de genes em carcinomas de células escamosas de cabeça e pescoço, o gene MX1 foi identificado como diferencialmente expresso. Dessa forma, para elucidar a função destes genes no controle da carcinogênese, o presente estudo buscou identificar ligantes celulares das proteínas MX1 e ADAM23 por meio de rastreamentos de duplo-híbrido, usando bibliotecas de cDNA de cérebro fetal humano. Os rastreamentos com a proteína ADAM23 não geraram resultados positivos por isso não são aqui discutidos. Foi realizado rastreamento com a proteína MX1, que resultou em aproximadamente 1,0x106 transformantes, dos quais 74 foram confirmados pelo ensaio de duplo-híbrido e codificam para 9 ligantes já conhecidos e 21novos ligantes prováveis de MX1. Entre esses novos ligantes prováveis estão proteínas que já haviam sido descritas como ligantes de MX1, incluindo a própria proteína MX1, o que valida os resultados obtidos com este rastreamento. Além disso, grande parte dos ligantes identificados são fatores envolvidos no processo de SUMOilação de proteínas, na formação de corpúsculos nucleares denominados PML-NB e uma série de proteínas relacionadas ao controle da transcrição e apoptose...

Obtenção de constantes elásticas da madeira de duas espécies de Pinus sp

There are many studies about longitudinal modulus of elasticity of wood, but you can´t say the same of transverse modulus, especially for conifers. The study aimed to characterize and compare the species Pinus elliottii var. elliottii and Pinus elliottii var. elliottii x Pinus cariabeae hondurensis (hybrid), and the longitudinal modulus of elasticity (E) and lateral (G) in bending, to analyze the modulus of elasticity in different spaces and to verify the species studied the ideal range is equal to 21 times the height of the specimen, as prescribed in the normative document NBR 7190/1997, as well as analyzing the relationship G = E/20 defined in the normative document NBR 7190/1997. The wood came from the farm located in Paranapanema, split at the mill São José and the rest of the work was conducted at the Experimental Itapeva Campus - UNESP. Were removed fourteen specimens of each species. The average values of the modulus of elasticity and cross were, respectively, 5828 MPa and 452 MPa for Pinus elliottii var. elliottii and 6407 MPa and 320 MPa for the species of Pinus elliottii var. elliottii x Pinus cariabeae hondurensis (hybrid). The trend lines for the plotted graphs showed an exponential behavior to near linear 21he will equal the constant after this value. We have found the relationship G = E/13, for Pinus elliottii var. elliottii and G = E/20 for hybrid. The results of the modulus and strength for Pinus elliottii var. elliottii and the hybrid were lower than those reported in the literature, showing that this batch inferior quality to apply to structures

Síntese e caracterização dielétrica de filmes finos de Bi3NbO7 obtidos pelo método dos precursores poliméricos

Bi3NbO7 thin films were prepared by the polymeric precursor method. The precursor solutions were prepared with excess of bismuth ranging from 0% to 10% and the pH was controlled to be maintained between 8 and 9. This control was done by adding to the solution niobium and ethylene glycol. The final solution was clear and free of precipitation. After obtaining the precursor solution, has begun the process of characterization of powders with thermogravimetry (TG), differential thermal analysis and X-ray analysis (XRD). The films were obtained by the polymeric precursors, the method is advantageous because it is simple, and low cost involves steps and controlled stoichiometry. The films were annealed and characterized by XRD and SEM and also characterized according to their dialectics properties. We observed that the best results were obtained when the film is thermally at 800 ° C for two hours and 860 ° C for two hour. Under these conditions we obtain Bi3NbO7 thin films with good homogeneity, uniform distribution of the grains, but with the formation of secondary phase, which does not occur in treatments with lower temperature. The dielectric characterization showed that the produced film showed good characteristics with high dielectric constant and low loss
