Autoscopia: um procedimento de pesquisa e de formação

This article considers a procedure for data collection called autoscopy. Autoscopy entails the video recording of a practice with the purpose of allowing analysis and self-evaluation by one of the protagonists of that practice. The objective of the video recording is that of apprehending the actions of the agent (or agents), the scenario, and the plot that make up a situation. The recorded material is subjected to sessions of analysis after the action that aim at the understanding of the reflective process of the agent (or agents) through their verbalizations during the analysis of video recorded scenes. The present text introduces a theoretical basis for the procedure of autoscopy, deals with advantages and limitations of its use, as well as with aspects that deserve attention and, finally, describes the authors' experiences in two studies in which the procedure was employed. Starting from these two experiences, differences and similarities are pointed out between the studies, especially regarding the participants, object, and the time distribution of the video recordings. The authors draw considerations about the formative-reflective potential of the procedure, both for research situations and for the learning and training of various professionals, considering it to be an excellent educational instrument. It is, however, vital to keep in mind the need to recognize and return to the teacher, as an autoscopic participant, his condition as subject of his own profession, thereby promoting, besides the self-evaluation, also the autonomy of his thinking and doing.

Politetrafluoroetileno e esclera humana no tratamento cirúrgico de perfuração escleral em coelhos

Purpose: An experimental study to evaluate the behavior of polytetrafluoroethylene (Gore-Tex®) compared with human sclera, in scleral perforations induced in rabbits eyes was performed. Methods: Twenty-two eyes of rabbits were submitted to scleral perforation followed by Gore-Tex® graft in the left eye and human sclera graft in the right eye respectively. During one month the postoperative evolution was analyzed every day: intensity of hyperemia, presence of infection, secretion, rejection and tonicity of the eyes. Results: No cases of secretion, infection or rejection were observed. The histological sections showed fibrosis in the eyes with Gore-Tex®, good adhesion and epithelization. Conclusion: The Gore-Tex® showed to be a plausible material to be used as graft in scleral defects with some advantages such as easy obtention, good handling and durability.

Tratamento clínico da epilepsia resistente

The authors analysed 34 cases of resistant epilepsy (20 males and 14 females, mean age 23 years), treated clinically between February/1984 and May/1986. The patients underwent neurological, neuropsychological, psychological, psychiatric, cerebrospinal fluid, electroencephalographic, tomographic and/or angiographic examination. Most of the patients had complex partial seizures. The etiology was unknown in 19 patients (55.8%), probable neurocysticercosis in 6, perinatal hypoxia in 5, delivery trauma in 3 and probable sequelae of encephalitis in 2 patients. There was a clear past history of infantile febrile convulsion in 2 patients. Most patients received carbamazepine (mean dose 24.5 mg/kg/day), phenytoin (5 mg/kg and valproic acid (28 mg/kg) as monotherapy or in association. Twenty-two patients (64.7%) had more than 80% decrease of the seizure frequency. Nine resistant epilepsy-cases (24.5%) were evaluated as candidates for surgical therapy. The authors concluded that the resistant epilepsy is best managed by a specialised, multidisciplinary team, and pointed out the need of a correct diagnosis of the seizure type, an adequate drug therapy and a good engagement of the patient and his family in the treatment.

Quality and sensorial characteristics of osmotically dehydrated mango with syrups of inverted sugar and sucrose

Osmotic dehydration is becoming more popular as a complementary treatment in the processing of dehydrated foods, since it presents some advantages such as minimising heat damage to the colour and flavour, inhibiting enzymatic browning and thus dispensing the addition of sulphite and, mainly, reducing energy costs. The objective of the present study was to evaluate the effect of using inverted sugar and sucrose syrups as osmotic agents in the dehydration of mango. The conditions used in the dehydration process were: syrup/fruit ratio of 3:1 (v/w); temperature of 45ºC and constant stirring. The in natura and osmo-dehydrated fruits were evaluated in relation to pH, moisture content, water activity (a w) and soluble solids (ºBrix). Solids incorporation and loss in mass after the dehydration process were also determined. The sensory acceptance of the in natura and osmo-dehydrated fruits was determined for the attributes of aroma, flavour, texture and overall acceptance using a hedonic scale. Osmotic dehydration resulted in a reduction in moisture content and water activity, an increase in Brix and maintenance of the pH. The treatment with inverted sugar syrup resulted in more significant alterations in moisture content, a w, Brix, solids incorporation and loss in mass than the treatment with sucrose syrup. Mangos osmo-dehydrated with inverted sugar (55.3% inversion rate) syrup obtained acceptance similar to in natura mangos, this treatment being considered the most adequate for dehydration purposes.

Nanochromics: old materials, new structures and architectures for high performance devices

Due to the development of nanoscience, the interest in electrochromism has increased and new assemblies of electrochromic materials at nanoscale leading to higher efficiencies and chromatic contrasts, low switching times and the possibility of color tuning have been developed. These advantages are reached due to the extensive surface area found in nanomaterials and the large amount of organic electrochromic molecules that can be easily attached onto inorganic nanoparticles, as TiO2 or SiO2. Moreover, the direct contact between electrolyte and nanomaterials produces high ionic transfer rates, leading to fast charge compensation, which is essential for high performance electrochromic electrodes. Recently, the layer-by-layer technique was presented as an interesting way to produce different architectures by the combination of both electrochromic nanoparticles and polymers. The present paper shows some of the newest insights into nanochromic science.

Discrepancies among ecological, household, and individual data on fruits and vegetables consumption in Brazil

Information on fruits and vegetables consumption in Brazil in the three levels of dietary data was analyzed and compared. Data about national supply came from Food Balance Sheets compiled by the FAO; household availability information was obtained from the Brazilian National Household Budget Survey (HBS); and actual intake information came from a large individual dietary intake survey that was representative of the adult population of São Paulo city. All sources of information were collected between 2002 and 2003. A subset of the HBS, representative of São Paulo city, was used in our analysis in order to improve the quality of the comparison with actual intake data. The ratio of national supply to household availability of fruits and vegetables was 2.6 while the ratio of national supply to actual intake was 4.0. The discrepancy ratio in the comparison between household availability and actual intake was smaller, 1.6. While the use of supply and availability data has advantages, as lower cost, must be taken into account that these sources tend to overestimate actual intake of fruits and vegetables.

Efeito da fotoperiodicidade na taxa de prenhez em ratos isogênicos (F344)

O uso de animais isogênicos apresenta grandes vantagens experimentais, como uniformidade fenotípica e genotípica (reduzindo o número de animais em experimentos) e histocompatibilidade, permitindo, assim, o acúmulo de informações e a repetibilidade dos experimentos. A linhagem isogênica de Rattus norvegicus Fischer 344 existe há 90 anos, entretanto pouco se sabe sobre as razões de seu baixo índice reprodutivo. O presente estudo demonstrou que ratos Fischer F344 são fotorresponsivos quanto à reprodução, tendo seus índices de prenhezes acrescidos com o aumento do fotoperíodo. Os melhores índices são obtidos quando os machos são submetidos a 14 horas de luz e fêmeas a 16 horas de luz, indicando dimorfismo sexual na fotorresponsividade.

Controle de vetores utilizando mosquitos geneticamente modificados

Formas químicas de controle de mosquitos vetores são ineficazes, levando ao desenvolvimento de novas estratégias. Assim, foi realizada revisão das estratégias de controle genético de populações de mosquitos vetores baseada na técnica do inseto estéril. Uma delas consiste na liberação de machos esterilizados por radiação, a outra, na integração de um gene letal dominante associado a um promotor específico de fêmeas imaturas. Entre as vantagens sobre outras técnicas biológicas e químicas de controle de vetores estão: alta especificidade, não prejudicial ao meio ambiente, baixo custo de produção e alta eficácia. O uso desta técnica de modificação genética pode vir a ser uma importante ferramenta do manejo integrado de vetores
