Abstract: the clonicity detection in the lymphoproliferative syndromes by studying the rearrangement of the immunoglobulin genes and of the t-receptor cells is used to make clear if a proliferation or infiltrate of lymphocytes is malignant or not. this type of study is particularly useful in the presence of cutaneous lesions whose lymphoid or dermatological origin is difficult to define. by the pcr-heteroduplex technique, the genes of the immunoglobulin heavy chain and of the t-cell receptor chain were studied in 10 patients that presented dermatological manifestations attributable to some kind of cutaneous lymphoma. clonal rearrangement was observed in 7 patients, which allowed to confirm the diagnosis of mycosis fungoides and other types of cutaneous lymphomas. it was not possible to confirm a lymphoid process of malignant character by this technique in 3 patients who did not show clonal rearrangement. the usefulness of the study was proved when in the presence of a skin affection, it was difficult to differentiate a dermatological process from a proliferative syndrome with cutaneous manifestations.
Diagnóstico de linfomas cutáneos mediante detección de clonalidad por PCR-heterodúplex Diagnosis of cutaneous lymphomas by clonicity detection through PCR-heteroduplex technique

Abstract: La detección de clonalidad en los síndromes linfoproliferativos mediante el estudio del reordenamiento de los genes de las inmuglobulinas y del receptor de células T, es utilizada para esclarecer si una proliferación o infiltrado de linfocitos es maligno o no. Este tipo de estudio es de particular utilidad en presencia de lesiones cutáneas cuyo origen linfoide o dermatológico resulta difícil de definir. Mediante la técnica de PCR-heterodúplex se estudiaron los genes de la cadena pesada de las inmunoglobulinas y de la cadena gamma del receptor de las células T, en 10 pacientes que presentaban manifestaciones dermatológicas atribuibles a algún tipo de linfoma cutáneo. Se observó reordenamiento clonal en 7 pacientes, lo cual permitió confirmar el diagnóstico de micosis fungoide y otros tipos de linfomas cutáneos. En 3 pacientes que no mostraron reordenamiento clonal, no fue posible confirmar por esta técnica un proceso linfoide de carácter maligno. Se demostró la utilidad del estudio cuando en presencia de una afección en la piel, es difícil diferenciar un proceso dermatológico de un síndrome linfoproliferativo con manifestaciones en piel.

Abstract: the aim of this study was to examine the effects of pre-exercise carbohydrate ingestion on performance and glycemic response during a strength training session. eight male volunteers performed 2 strength exercise sessions with the ingestion of a carbohydrate (maltodextrin) or placebo drink 15 minutes before each session (7 exercises with 3 sets at 70% of 1 maximum repetition). the trials were performed 7 days apart from each other and their order was randomized. glycemia was measured at 4 times: before the drink ingestion, 15 minutes after the drink ingestion, halfway through the training and at the end of the exercise session. the total performance was affected by variation on achieved repetitions in the different days, which were inserted in the total load rate analysis performed in the respective sessions (repetitions · sets · load). heart rate was continuously monitored and lactate concentration was measured at the end of session. glycemia increased only at 15 minutes after the carbohydrate drink ingestion (from 98.25 ± 17.77mg/dl to 133.12±22.76 mg/dl, p= 0.015) , while on the placebo drink day no significant changes were observed (from 98.25 ± 13.69 mg/dl to 94.38 ± 12.21 mg/dl, p=1.000). the total load rate, heart rate and final lactate concentration were not different in the two strength exercise sessions. although pre-exercise glycemia was increased after the carbohydrate drink ingestion, the results do not indicate that carbohydrate ingestion before strength exercise session can be an efficient supplementation in order to improve physical performance.

Abstract: the aim of this study was to compare two self-etching and a total-etch adhesive systems by assessing their shear bond strength to bovine enamel and the microleakage on class v composite restorations prepared on bovine enamel. bovine teeth selected and allocated in three groups: group 1: scothbond multi-purpose; group 2: clearfil liner bond 2v; group 3: etch & prime 3.0. for the microleakage test, each group was composed of ten class v restorations on the buccal surface. two examiners attributed scores ranging from 0 (without leakage) to 3 (maximum leakage) to determine silver nitrate penetration at enamel-composite interface. microleakage data were analyzed statistically by kruskal-wallis and mann-whitney tests at 5% significance level. for the bond strength test, ten teeth of each group were included, had their buccal surfaces flattened in order to obtain a 3-mm-diameter area to which a resin cylinder was bonded. after one week, the specimens were tested in shear strength at a crosshead speed of 0.5 mm/min. bond strength data were treated by anova and lsd tests at 5% significance level. the debonded interfaces were examined under scanning electron microscopy. no leakage was observed along enamel margins. means (± sd) in mpa were: 18.75 (±5.83), 22.17 (±4.95) and 14.93 (±6.7) for groups 1, 2, and 3, respectively. according to the results of this study, the self-etching primer systems presented statistically similar behavior (p>0.05) to that of the total-etch adhesive system (used as a control), not only regarding marginal leakage at bovine enamel-composite resin interface, but also regarding the shear bond strength of the bovine enamel. however, the self-etching primer systems differed significantly (p>0.05) to each other, with better results for clearfil liner bond 2v. in conclusion, the self-etching primer systems had a performance comparable to that of the total-etch adhesive system.

Abstract: The feasibility of using constructed wetlands (CWs) for the mitigation of pesticide runoff has been studied in the last decade. However, a lack of related data was verified when subsurface flow constructed wetlands (SSF CWs) are considered for this purpose. In the present work, SSF CWs were submitted to continuous ametryn addition and evaluated during an 11-week period, with the aim of determining the feasibility of these systems for mitigation of contaminated water. Ametryn was not added to one CW cell in order to provide a control for the experiments. Monitoring of treatment performance was executed by standard water quality parameters, ametryn chromatography quantification and macrophyte (Typha latifolia L.) nutritional and agronomic property analysis. Results indicated that 39% of the total initially added amount of ametryn was removed, transferred or transformed. Herbicide metabolism and mineralisation were carried out by chemical and biological mechanisms. No statistic differences were observed in nutritional contents found in the T. latifolia crops of the CWs after the experimental period. Moreover, the biomass production (one valuable source of renewable energy) was equal to 3.3 t·ha-1 (dry matter) in wetland cells. It was concluded that constructed wetland systems are capable of mitigating water contaminated with ametryn, acting as buffer filters between the emission sources and the downstream superficial water bodies.

Coproantígenos de Fasciola hepatica de posible utilidad en el diagnóstico de la fascioliasis
Espino,Ana M.; Borges,Amarilys; Duménigo,Blanca E.;
Revista Panamericana de Salud Pública , 2000, DOI: 10.1590/S1020-49892000000400003
Abstract: this study describes which antigens of fasciola hepatica are present in the feces of patients with chronic fascioliasis and in the feces of rats infected experimentally with f. hepatica metacercariae. using a western blot assay technique with hyperimmune serum obtained from excretory-secretory antigens of adult f. hepatica, we found in the patients' feces antigens of possible diagnostic interest, with molecular weights of 14, 19, 20, 23, 25, 32, 46, 51, and 62 kilodaltons (kda). in addition, we showed that the peptides of 14, 20, 23, and 51 kda are also recognized by the majority of the sera from chronic patients. we used affinity chromatography to purify the antigens present in the feces of rats that had been infected for 6 to 12 weeks, using es78 monoclonal antibody bound to cnbr-activated sepharose 4b. through that approach, we identified six polypeptides, of 11, 14, 26, 32, 47, and 51 kda; three more polypeptides, of 17, 24, and 66 kda, could only be identified in the feces of rats that had been infected for 10 to 12 weeks. our results suggest that these polypeptides could be antigens common to both parasitic stages. this is particularly true for the polypeptides of 14, 24, 26, and 51 kda, because they reacted with the immune sera, the human sera, and the es78 monoclonal antibody. these polypeptides could be important markers for acute and chronic fascioliasis.

Abstract: national and international research points to the magnitude of domestic violence, even underestimated, and some studies have identified the mother as the main aggressor of their children. we aimed in this study to identify the reasons why women who live in contexts of alcohol, drugs, and violence are aggressive with their children. the approach is qualitative, and data was collected using interviews and topical life histories. through thematic content analysis, three central themes were inferred from the words of those interviewed: living with loss: "... i was left to the world"; living with alcoholism, poverty, and violence in families; and living with affection and the lack of affection. we identified that the family and social context in which the women lived during their process of socialization in their original family home unites factors that contribute to manifest acts of violence against their children.

Abstract: Investigaciones nacionales e internacionales muestran la magnitud de la violencia doméstica, aunque es subestimada, y algunos de esos estudios han identificado a la madre como el principal agresor de sus hijos. Se busca en este estudio identificar las razones por las que mujeres que viven en contextos de alcohol, drogas y violencia agreden a sus hijos. El enfoque es cualitativo. Para la recolección de los datos se utilizó la entrevista y la historia de vida tópica. A través del análisis de contenido temático se deduce de las palabras de los entrevistados tres temas centrales: Viviendo con la pérdida: "... Llegué al mundo", Viviendo con alcoholismo, pobreza y violencia en familia; Viviendo con afecto y desafecto. Se identificó que el contexto familiar y social en que vivían las mujeres durante su proceso de socialización en el hogar familiar reúne factores que contribuyen a los actos manifiestos de violencia contra sus hijos.
