Abstract: the present work evaluated 36 arabic coffee (coffea arabica l.) f3 progenies, originated from crosses among cultivars catuaí vermelho iac 46 and catuaí vermelho iac 81 and access iac 1110 (ba-10). this last cultivar came from india and exhibits sh2 and sh3 rust resistance genes. the experiment was installed in 1988 at the experimental center of the agronomic institute (iac/apta), in campinas, using random blocks design with six repetitions and two plants per plot. field evaluations included yield (average of seven annual harvests), vegetative vigor, resistance to leaf rust, plant size, color of young leaves and complete fruit maturation period. based on these evaluations, plants exhibiting high yield, good vegetative vigor, low height, and resistance to the leaf rust agent hemileia vastatrix were selected. fruit yield of selected plants was calculated and seeds were characterized according to type (flat, peaberry and elephant), outturn and grain size. a total of 11 optimal f3 progenies were identified as rust resistant. by further classifications, 39 plants out from these progenies were selected, along with 15 plants from other 25 evaluated progenies. laboratory analyses lead to a final selection of 18 coffee trees, all exhibiting leaf rust resistance, high yield and low height. also, f4 progenies of selected plants had been evaluated regarding height and leaf rust resistance, at seedling stage, in greenhouse conditions. eighteen plants were selected for further analysis and move forward from f3 to f4 generation in the coffee breeding program developed by iac.

Abstract: this study investigates the frequency of different stages of spermatogenic cycle in synthetic bulls, being 12 from braford and 8 from brangus-ibagé breed with normal and altered semen quality, classified as sound (group a) and unsound (group b) animals by andrological examination. the staging criteria includes the proliferative (stage i), meiotic (stage ii) and the maturation (stage iii) periods of the spermatogenesis. the braford bulls present different frequencies between groups within stages ii and iii. among brangus-ibagé bulls there are different frequencies between groups just for stage ii. the results indicate that spermatogenesis progress adequately in the stage i on synthetic bulls with different semen quality. during the period in which meiotic divisions (stage ii) and spermatid maturation (stage iii) occur there are disturbs in the spermatogenesis of the unsound bulls. the present proposition to cluster the stages of the spermatogenic cycle, forgives a practical method to evaluate the dynamic of germinative epithelium in bulls with different breeding soundness classification.

Abstract: background: the objective was to determine the feasibility of using vital blue dye to map sentinel lymph nodes (sln) in gastric cancer using a minimally invasive technique. methods: sentinel lymph node biopsy was performed on 12 patients with gastric adenocarcinoma that did not have metastatic lymph nodes during clinical staging. vital blue dye was injected around four quadrants of the tumor, 0.5 ml in each quadrant. the lymph nodes that stained blue 5 minutes after dye injection were classified as sln. histopathological analysis of the sentinel lymph nodes was done according to routine evaluation of other lymph nodes, with hematoxylin and eosin (he) staining. if the sln was negative for malignancy by means of he, it was further examined by immunohistochemistry. results: sentinel lymph node biopsies in gastric cancer patients were performed from july 2002 to december 2004. twelve patients were enrolled at the study, being 8 women, with a mean age of 64.5 years (range, 48 to 87). a mean of 3.25 slns (range, 2 to 6) were identified in each patient. the feasibility of the procedure was 100%, and its accuracy was 91.6%. in 11 of 12 patients, it was possible to predict the regional lymph nodes status by concordance of the histopathological analysis of sln and non-sentinel lymph nodes (nsln). conclusion: the sentinel lymph node biopsy in gastric cancer technique has demonstrated to be feasible, with the use of vital blue dye. the procedure is promising as a minimally invasive technique of gastric tumors staging, in our series.

Abstract: Se ofrece un inventario para evaluar el grado desatisfacción sentido por mujeres hacia el apoyo socialrecibido durante su embarazo. Se presenta el sistemade variables empleado para la construcción del mismo ylos resultados obtenidos al aplicarlo a 271 gestantes,residenciadas en el área Metropolitana de Caracas,Venezuela, con edades entre los 14 y 42 a os. Losresultados revelaron variaciones importantes en elporcentaje de embarazadas que presentaron síntomasdepresivos en función a la ausencia de la pareja, a lainsatisfacción sentida por la gestante hacia el apoyosocial recibido y al estrato social al cual pertenecía. Laseveridad de los síntomas se asoció de formasignificativa con la ausencia de la pareja y lainsatisfacción con el apoyo recibido. Se concluyó que elinventario permitió obtener información sobre algunasnecesidades surgidas durante el embarazo, conocer siéstas fueron atendidas o no, conocer el grado desatisfacción que se experimentó hacia el apoyo socialrecibido e identificar las personas más significativas dela red social.

Abstract: Se presentan los resultados obtenidos al estudiar lasinteligencias cristalizada y fluida de una muestraconformada por 736 ni os y ni as de 7 a os de edad.Evaluación hecha en el marco del estudio Condicionesde Vida de la Población del Eje Llanero, zonas Oriental(Estados Anzoátegui, Monagas, Sur de Aragua y Estede Guárico) y, Occidental (Estados Táchira, Barinas yOeste de Portuguesa), en Venezuela. Se empleó el TestBreve de Inteligencia de Kaufman K-BIT (1997),subpruebas Vocabulario Expresivo y Matrices. Secomparó el desempe o según sexo, estrato social yentre subpruebas. Se encontraron diferenciassignificativas a favor del sexo masculino tanto en larealización de tareas referidas a la inteligenciacristalizada como a la fluida. En ambos tipos de tareaslos ni os y ni as ubicados en los estratos sociales conmejores condiciones socioeconómicas (I+II+III)mostraron tener más ventajas en comparación con lasmuestras de los estratos IV y V, dichas diferenciasalcanzaron significación estadística. Por otra parte, losresultados también evidenciaron un mejor rendimientoen la subprueba de Vocabulario Expresivo encomparación con la subprueba de Matrices, por lo quese concluyó que la inteligencia cristalizada, encomparación con la inteligencia fluida, ha sido másestimulada en este grupo de ni os y ni as de 7 a os deedad, indistintamente del sexo y el estrato social.

Abstract: Racional - A doen a hepática alcoólica é enfermidade grave e freqüente e o seu diagnóstico nem sempre é fácil. Objetivo - Avaliar a contribui o de depósitos de imunoglobulina A (IgA) nos sinusóides hepáticos para o diagnóstico da hepatopatia alcoólica. Casuística e Método - Foi estudada a presen a de imunoglobulina A por imunofluorescência direta em 59 pacientes submetidos a pun o biopsia hepática, indicada por altera es clínicas ou laboratoriais sugestivas de hepatopatia cr nica. Resultados - Constatou-se deposi o significativa de imunoglobulina A hepática em alcoolistas, em compara o com os n o-alcoolistas, com sensibilidade de 76% (IC95%: 54,5-89,8) e especificidade de 73,5% (IC95%: 55,3-86,5). Em indivíduos que apresentavam só o álcool como agente etiológico da hepatopatia, comparados com o grupo de portadores dos vírus B e C, os resultados foram ainda mais significativos, com sensibilidade de 85,7% (IC95%: 56,2-97,5) e especificidade de 89,5% (IC95%: 65,5%-98,2%). Conclus o - A deposi o de imunoglobulina A nos sinusóides hepáticos apresenta sensibilidade e especificidade para o diagnóstico da les o hepática induzida pelo álcool. Esse recurso pode ser particularmente útil quando a histologia convencional n o consegue definir a causa específica da altera o encontrada.
