Abstract: explaining codon evolution in the standard genetic code is a remarkable subject in molecular biology. there are many works which try to develop a model to represent this evolution, sometimes using a certain amount of mathematical tools. the present work has as its main objective to explain one possible dynamical evolution model, which is based in the algebraic approach proposed in 1993 by hornos and hornos. this model made an analogy between the evolution of elementary particles and evolution of codons. as a result, the symmetry group that better adjusts degeneracy of the genetic code is the simplectic group sp(6). the dynamical model present here is based in the 3 dimensional weight space of sp(6), called codon space. this space is invariant under the action of the octahedral group. a map, a3 ? a3, was constructed using an equivariance principle and its action in the codon space was observed. the results were based in the analysis of the attractors and their preserved symmetries. the dynamical system action reproduces the main aspects of the labeling proposed in the algebraic approach. moreover, the map separates the codons in distinguished sets, coupling codons from the same aminoacid in the same attractor. these dynamical results indicate that the algebraic model proposed in 1993 may be an important contribution to explain codon evolution, both in the algebraic and in the dynamical aspects.

Abstract: Explaining codon evolution in the standard genetic code is a remarkable subject in Molecular Biology. There are many works which try to develop a model to represent this evolution, sometimes using a certain amount of mathematical tools. The present work has as its main objective to explain one possible dynamical evolution model, which is based in the algebraic approach proposed in 1993 by Hornos and Hornos. This model made an analogy between the evolution of elementary particles and evolution of codons. As a result, the symmetry group that better adjusts degeneracy of the genetic code is the simplectic group Sp(6). The dynamical model present here is based in the 3 dimensional weight space of Sp(6), called Codon Space. This space is invariant under the action of the Octahedral Group. A map, 3 -> 3, was constructed using an equivariance principle and its action in the Codon Space was observed. The results were based in the analysis of the attractors and their preserved symmetries. The dynamical system action reproduces the main aspects of the labeling proposed in the algebraic approach. Moreover, the map separates the codons in distinguished sets, coupling codons from the same aminoacid in the same attractor. These dynamical results indicate that the algebraic model proposed in 1993 may be an important contribution to explain codon evolution, both in the algebraic and in the dynamical aspects.

Abstract: a field experiment was carried out in order to study the effect of two kinds of parcially protected environments: greenhouse cover with transparent polyethylene of low density and plastic screan windbreaks, to grow rubber-tree rootstocks, during the winter season in campinas, sp, brazil. diameter, height, leaf area, and dry weight of young rubber plants were mensured, and results showed that protected plants by windbreaks did not present significant differences during the initial growing stage, in relation to the non protected ones. the use of greenhouse, however, caused increments in diameter (60%), height (108%), leaf area (266%), and dry weight (286%) of the rootstocks. atfer six months, considering that a minimum diameter of 8 mm is needed to perform green budding, 60% of rootstocks conducted inside the greenhouse were in condition to be budded, while in the two other treatments, the plants did not reach the minimum diameter.

Revista da Associa??o Médica Brasileira , 1998,
Abstract: Após a confirma o clínica e laboratorial de hiperinsulinismo, o principal problema consiste na localiza o precisa da les o no parênquima pancreático, propiciando tratamento cirúrgico adequado. OBJETIVO: Analisar os métodos utilizados para o diagnóstico e localiza o pré e intra-operatório dos insulinomas, bem como as técnicas e os resultados do tratamento cirúrgico. MéTODOS: Foram estudados 59 casos consecutivos de insulinoma submetidos a interven o cirúrgica. Cada um dos métodos utilizados para a localiza o pré-operatória dessas les es foi avaliado quanto à sua eficiência em confronto com os achados intra-operatórios. A palpa o do pancreas, isoladamente ou associada à ultra-sonografia intra-operatória, como métodos de localiza o dos insulinomas, foi também estudada. Os tipos de interven o cirúrgica foram analisados quanto aos seus resultados imediatos e tardios. RESULTADOS: Dos 59 insulinomas, 55 eram benignos e quatro, malignos. Dos métodos utilizados para a localiza o pré-operatória, a ultra-sonografia foi eficiente em 28,1% dos casos, a tomografia computadorizada em 25%, a ultra-sonografia endoscópica em 27,2%, a arteriografia seletiva em 54,1% e a colheita de amostras de sangue portal para dosagem de insulina em 94,4% dos casos. A palpa o bidigital, durante a interven o cirúrgica, localizou as les es em 54/55 casos (98,2%). A ultra-sonografia intra-operatória foi decisiva em apenas um caso. Cinco doentes apresentavam neoplasia endócrina múltipla tipo I e em todos as les es pancreáticas eram múltiplas. Foram efetuadas 29 enuclea es e 32 ressec es pancreáticas nos doentes com les es benignas. Os doentes com les es malignas foram submetidos a ressec es pancreáticas e quimioterapia. N o houve mortalidade, porém observaram-se complica es (fístulas) em 29/59 casos. Os resultados foram bons em 98,1% dos doentes com les es benignas. Apenas um dos doentes com les es malignas sobreviveu cinco anos. Três doentes portadores de les es benignas e submetidos a ressec es pancreáticas evoluíram com diabetes tardiamente. CONCLUS ES: A localiza o pré-operatória n o é absolutamente necessária desde que a palpa o bidigital associada a ultra-sonografia intra-operatória permite a localiza o de todas as les es. As enuclea es devem ser utilizadas, quando possível, de preferência às ressec es pancreáticas nas les es benignas.

Abstract: this paper describes the rainfall pattern during the day along the different months of the year, calculated on an hourly basis for three sites: campinas, pindorama and ubatuba, sp, brazil, utilizing data series from 1957 to 1976. results indicate that there is significative difference in the total of the hourly rainfall in the months of november to march in campinas; october to april in pindorama, and october to june in ubatuba. results of the hourly frequencies of rainfall are similar to those of total rainfall for campinas and pindorama. for ubatuba, the hourly frequence of rainfall shows significant differences for all months of the year. during the mouths that show significant differences, the morning period is the most appropriate to realize agricultural practices, in which rainfall probability is reduced. during the months that do not show significant differences, the probability of rainfall occurrence is very reduced, less than 10%, in average, in all hours of the day, being possible to program agricultural practices during the whole period.

Abstract: A 12-month study was conducted in 4 communal grazing areas in the Bushbuckridge region, Limpopo Province, South Africa. The main objective was to investigate the impact of reduced acaricide application on endemic stability to bovine babesiosis (Babesia bigemina and Babesia bovis) and anaplasmosis (Anaplasma marginale) in the local cattle population. To this end 60 cattle in each communal grazing area were bled at the beginning and the conclusion of the experimental period and their sera were assayed for B. bovis, B. bigemina and Anaplasma antibodies. Cattle in the intensively dipped group were dipped 26 times and maintained on a 14-day dipping interval throughout the study, whereas cattle in the strategically dipped group were dipped only 13 times. Three cattle, from which adult ticks were collected, were selected from each village, while immature ticks were collected by drag-sampling the surrounding vegetation. During the dipping process, a questionnaire aimed at assessing the prevalence of clinical cases of tick-borne disease, abscesses and mortalities was completed by an Animal Health Technician at each diptank. An increase in seroprevalence to B. bovis and B. bigemina and a decrease in seroprevalence to Anaplasma was detected in the strategically dipped group while in the intensively dipped group the converse was true. Amblyomma hebraeum was the most numerous tick species on the cattle, and Rhipicephalus (Boophilus) microplus was more plentiful than Rhipicephalus (Boophilus) decoloratus. Drag samples yielded more immature stages of A. hebraeum than of Rhipicephalus (Boophilus) spp. The incidence of clinical cases of tick-borne disease and of abscesses increased in the strategically dipped group at the start of the survey.

Abstract: after establishing the diagnosis of an insulinoma the next step is its localization in order to perform the most suitable management approach. purpose: to evaluate the methods used for the diagnosis of insulinoma and the localization of its site as well as the results of the surgical treatment. methods: fifty nine consecutive patients with pancreatic insulinomas were studied. the discriminative power of the preoperative investigations in the localization of insulinomas was analysed. special attention was focused to the intra operative methods of tumor localizations. the early and late results of the surgical treatment were also investigated. results: there were 55 benign cases and 4 malignant tumors. preoperative localization was attempted by using ultrasonography (positive in 28.1%) ct imaging (positive in 25%), selective arteriography (positive in 54.1%), endoscopic ultrasonography (positive in 27.2%) and assay of portal plasma insulin levels (positive in 94.4%). in 54/55 cases (98.2%) the tumors were identified intraoperatively by palpation. by addition of intraoperative ultrasonography all lesions were identified and successfully removed without mortality. five patients had multiple endocrine neoplasias all with multiple lesions in the pancreas. in patients with benign lesions 29 enucleations and 32 resections were performed. pancreatic fistulas were the most common complication (29/59). excluding the patients with malignant lesions the recovery rate was 98.1%. three patients who underwent corporo caudal pancreactectomy developed diabetes. conclusions: the preoperative localization is not necessary, since a combination of palpation and intraoperative ultrasonography can deal with most cases. enucleation when possible is the best choice for benign lesions.
