ABSTRACT
Background: Meat is an important source of nutrients. However, in recent years their consumption is associated with chronic-degenerative diseases giving it the perception of "unhealthy food" Given that meat is an affordable source of quality protein; its improvement entails a huge challenge for the industry and science. Methods: The search and structured review of the literature in the last ten years in the scientific databases of articles related to the elaboration of restructured meat products with functional ingredients derived from plants. Objective: This work presents a general overview, as well as the most representative studies on the elaboration of restructured meat with ingredients from plants considered functional. Conclusions: The present review is intended to emphasize the use of plant natural ingredients in the elaboration of functional restructured meat products as an alternative for consumers allowing the inclusion of functional compounds beneficial to human health in their daily diet
Antecedentes: La carne es una fuente importante de nutrientes. Sin embargo, en los últimos años su consumo se asocia a enfermedades crónico-degenerativas dando la percepción de alimento poco saludable. Dado a que es una fuente accesible de proteína de calidad, su mejoramiento implica un enorme desafío para la industria y la ciencia de la carne. Método: La revisión estructurada de diversos artículos de investigación encontrados en bases de datos científicas, durante los últimos 10 años, relacionados a la elaboración de reestructurados cárnicos con derivados de plantas considerados funcionales. Objetivo: Este trabajo presenta una revisión general, de los estudios más representativos sobre la elaboración reestructurados cárnicos elaborados con derivados de plantas considerados como funcionales. Conclusión: La elaboración de productos reestructurados cárnicos funcionales con la utilización de derivados vegetales, puede considerarse una alternativa para los consumidores a fin de incluir compuestos funcionales beneficiosos para la salud humana en la dieta diaria

El presente artículo tiene como objetivo actualizar los conocimientos sobre las alteraciones morfológicas sobre las alteraciones morfológicas de las células epiteliales de la mucosa bucal de pacientes con diabetes tipo II, detectables con microscopía óptica y citología exfoliativa, con la finalidad de aportar datos que podrían ser útiles para el médico u odontólogo, junto a los análisis clínicos, para el diagnóstico precoz de esta enfermedad. Para una mejor comprensión y por la importancia de esta patología sistémica, se abordan los siguientes ítems: 1- diabetes mellitus tipo II y su impacto social, 2- diabetes mellitus tipo II y sus manifestaciones bucales, 3- citología bucal como método auxiliar del diagnóstico clínico. Los investigadores coinciden en que la diabetes causa alteraciones estructurales, morfológicas y morfométricas en las células bucales, fácilmente detectables por citología exfoliativa, por lo que esta técnica es viable para complementar el diagnóstico clínico y seguir la evolución de esta enfermedad.

A atividade larvicida de quatro saponinas monodesmosídicas (1-4) isoladas de Pentaclethra macroloba e de uma saponina bidesmosídica (5) isolada de Cordia piauhiensis foi avaliada sobre larvas de estágio 3 de Aedes aegypti. As larvas foram expostas a várias concentrações (500, 250, 100, 50, 25 e 12,5 mg/mL) das saponinas por um período de 24 h. Os resultados indicam que somente as saponinas 1-3 mostraram alta atividade larvicida, com CL50 variando de 18,6 a 27,9 mg/mL. Estes resultados ressaltam as potencialidades destas saponinas como possíveis agentes larvicidas naturais.
The larvicidal activity of the four monodesmoside saponins (1-4) isolated from Pentaclethra macroloba and one bidesmoside saponin (5) from Cordia piauhiensis was evaluated on 3rd instar larvae of Aedes aegypti. The larvae were exposed to serial concentrations (500, 250, 100, 50, 25 and 12.5 mg/mL) saponins for a period of 24 h. The results indicate that, only the saponins 1-3 showed high larvicidal activity, with LC50 ranging of 18,6-27,9 mg/mL. These results suggest that these can be used as natural larvicidal agents.
ABSTRACT
In the present study we investigated tissue changes in palatine (PG) and labial (LG) minor salivary glands from individuals who had died of alcoholic hepatic cirrhosis, to characterize histopathological parameters of alcoholic sialosis, that may be used for differential diagnosis. Samples obtained from autopsies were processed using cytochemical techniques for mucosubstances and immunocytochemical labelling for cytokeratines, PS 100 and T-cells. Both PG and LG showed dilated excretory ducts with atrophic epithelium, which contained PAS+ metachromatic material and detached cells. Intra and interlobular ductal hyperplasia was present in some areas, mainly in PG. CK expression was heterogeneous in ductal cells, and negative in acinar cells. Most of the acinar cell nuclei were normal, but some of them were atypical in shape and distribution. Myoepithelial cells, serous demilunes and the basal region of the cells of the striated ducts expressed PS 100. In PG, 85
of the mononuclear infiltrates expressed T-cell markers, whereas in LG only 40
of these cells were T-cells. These findings, in addition to other histopathological parameters seen in previous studies, may be used as indicators for differential diagnosis with other gland pathologies.
ABSTRACT
Samples from parotid, submaxillary, and von Ebner salivary glands of six chronic alcoholic individuals who had died of alcoholic hepatic cirrhosis were analyzed by topographic and histochemical routine stains and marked for cytokeratins; two normal adult individuals were used as control. Modifications in the acinar cells were found, but the most evident changes were observed in the ductal system: enlargement of major ducts, heterogeneous expression of cytokeratins and athrophy in epithelial cells, desquamated cells and stasis of content, and ductal hyperplasia in von Ebner glands. The lymphoplasmocytic infiltration does not represent the typical lymphocytic focus on Sj÷grens syndrome or other connective tissue pathologies. Our findings indicate that functional and structural variations are produced both in serous acini and ducts parotid, submaxilar and von Ebner glands affected by alcoholic sialosis.
ABSTRACT
Os autores apresentam caso de crianca de 5 meses, com desnutricao grave e quadro de frequente pneumonia de repeticao, submetida a intensa antibioticoterapia. A autopsia revelou endocardite por Candida sp., formando trombo de grandes proporcoes, ocluindo totalmente a cavidade ventricular direita. O fungo foi identificado por tecnicas de anticorpos fluorescentes, aliadas a hemoculturas e cultura de LCR positivas para Candida sp. Histologicamente formava graos semelhantes ao dos micetomas. Este comportamento tecidual nao e usual na candidiase e, segundo a literatura, por nos consultada, trata-se de caso unico que assim se apresenta
