INTRODUÇÃO: As síndromes linfoproliferativas formam um grupo heterogêneo de neoplasias malignas com diferentes comportamentos clínicos, fatores patológicos e características epidemiológicas e podem ter seu diagnóstico geral com base na morfologia das células linfoides observadas no sangue periférico. OBJETIVO: Testar a factibilidade diagnóstica do método de imunofenotipagem por citometria de fluxo para síndromes linfoproliferativas a partir da definição de um painel mínimo de anticorpos. MATERIAL E MÉTODOS: Participaram 47 pacientes para diagnóstico diferencial dos subtipos de síndromes infoproliferativas por citometria de fluxo, no período de julho de 2008 a julho de 2010, atendidos na Fundação HEMOPA. RESULTADOS: A mediana de idade dos pacientes foi de 68 anos, não houve diferença estatística entre os sexos e o subtipo de síndromes linfoproliferativas mais frequente foi a leucemia linfoide crônica/linfoma linfocítico de pequenas células B. CONCLUSÃO: O método de imunofenotipagem por citometria de fluxo, ao lado da morfologia, de amostras de sangue periférico mostrou-se uma metodologia auxiliar, segura, rápida, factível e não invasiva para o diagnóstico de síndromes linfoproliferativas crônicas a partir do painel de anticorpos sugerido.

This experiment aimed to evaluate the effect of increasing clomazone (sprayed alone or in mixture with ametryn) drift simulation on quantitative and qualitative aspects of orange production when applied at two developmental plant stages: flowering and initial fruit development (fruits 2 cm diameter or smaller). Increasing drifts of clomazone, in two formulations, and clomazone in mixtures with ametryn were tested. Fruit morphological features, fruit color, flower and fruit abortion and leaf chlorophyll content were evaluated. Simulated drift similar to the recommended dose of clomazone and clomazone plus ametryn caused fruit abortion in citrus at the stage of fruits 2 cm diameter or smaller. Lower drift doses did not result in fruit abortion. Fruit diameter reduction was observed with drift off above 25% of clomazone alone recommended rate and 50% when in mixture with ametryn or in microcapsule formulation. Clomazone drift at 50% of the recommended rate (alone or in mixture with ametryn ) caused clorotic and necrotic spots in the fruit peel. Drift did not affect juice quality in any of the treatments tested.

Costus stenophyllus or bamboo costus, despite its high ornamental potential, is still little known in the cut flower and ornamental plant market. The bamboo costus is a spiral ginger admired for its beautiful stems that are lined with brown colored alternating bands. This costus has rather straight and upright stems. Conical red inflorescences, which resemble the head of a snake, emerge from the base of the plants. The flowers are light yellow and emerge between the red scales on the rather long-lasting, attractive inflorescences. This study was carried out to evaluate the possibility of using these species as a garden plant, cut flower and cut stem. Thus, the characterization was made based on 28 characters of the plant, the leaves, the flower stem, the flowers, as well as season blooming characteristics and flower postharvest longevity.

The aim of this study was to perform a physicochemical and morphological characterization and compare the mechanical behavior of an experimental Ti-Mo alloy to the analogous metallic Ti-based fixation system, for mandibular angle fractures. Twenty-eight polyurethane mandibles were uniformly sectioned on the left angle. These were divided into 4 groups: group Eng 1P, one 2.0-mm plate and 4 screws 6 mm long; group Eng 2P, two 2.0-mm plates, the first fixed with 4 screws 6 mm long and the second with 4 screws 12 mm long. The same groups were created for the Ti-15Mo alloy. Each group was subjected to linear vertical loading at the first molar on the plated side in a mechanical testing unit. Means and standard deviations were compared with respect to statistical significance using ANOVA. The chemical composition of the Ti-15Mo alloy was close to the nominal value. The mapping of Mo and Ti showed a homogeneous distribution. SEM of the screw revealed machining debris. For the plates, only the cpTi plate undergoes a surface treatment. The metallographic analysis reveals granular microstructure, from the thermomechanical trials. A statistically significant difference was found (P < 0.05) when the comparison between both internal fixation techniques was performed. The 2P technique showed better mechanical behavior than 1P.
