Abstract: La enfermedad articular degenerativa, también conocida como osteoartrosis, afecta al 10 % de los adultos mayores de 60 a os de edad. Se caracteriza principalmente por dolor de la articulación afectada, crepitación, rigidez matinal y limitación progresiva de los movimientos de esa articulación. Todo esto conduce a un desgaste parcial o completo del cartílago articular. El tratamiento de la osteoartrosis de la rodilla constituye un gran desafío. Los avances recientes en el uso de la medicina regenerativa sugieren que las células madre adultas pudieran representar una alternativa promisoria en el tratamiento de esta enfermedad. En una paciente femenina de 61 a os de edad con osteoartrosis de la rodilla, se realizó el implante percutáneo de células mononucleares autólogas movilizadas a la sangre periférica mediante el factor estimulante de colonias granulocíticas, y se logró una rápida mejoría clínica y radiológica. Este resultado sugiere que el proceder empleado es un método factible, simple, seguro y menos costoso, para el tratamiento de las lesiones degenerativas articulares. The degenerative joint disease, also known as osteoarthrosis affects to 10% of elderlies aged 60. It is mainly characterized by pain in the involved joint, crepitation, morning stiff and a progressive limitation of movement of that joint leading to a partial or total wear of articular cartilage. The treatment of the knee osteoarthrosis is a great challenge. The recent advances in use of regenerative medicine suggest that adult stem cells could represent a promisor alternative in the treatment of this entity. In a female patient aged 61 presenting with knee osteoarthrosis authors placed a percutaneous implant of autologous mononuclear cells mobilized to peripheral blood by granulocyte colony-stimulating factor achieving a fast clinical and radiological improvement. This result suggests that the procedure used is a feasible, simple, safe and less expensive method for treatment of articular degenerative lesions.

A Geometric Morphometrics Study of Stigma-Anther Polymorphism in the Tropical Distylous Palicourea padifolia (Rubiaceae)  [PDF]
Angélica María Hernández-Ramírez, José A. Aké-Castillo
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.510160
Abstract:

Distyly is a floral polymorphism with long-styled flowers and short-styled flowers. Traditionally, floral traits in distylous species have been studied as a variable composed of several linear measurements. We proposed the use of a geometric morphometric approach to studying flower shape and entire flower design variation (including stigma-anther polymorphism) between morphs in Palicourea padifolia. The geometric morphometric approach allowed us to preserve the integrity of the floral form and to project the floral features on the same scale. Moreover, the visualization of a grid deformation allows us to describe shape differences between morphs as well as to estimate the variance-covariance matrix among floral traits. In this study, we demonstrated that flower shape and entire flower design differed between morphs. Intra- and inter-morph variations in the flower size were observed. The flower size has an effect on the anther position between morphs and among individuals. An association between flower shape and flower size was observed in both morphs. A pattern of floral features co-variation between the morphs was demonstrated in the species. In P. padifolia both morphs seemed to be internally coherent with respect to the developmental processes that produce flower shape variation. Changes in floral traits associated with flower size seemed to be more complex than those in the simple uniform expansion of the floral trait positions analogous between morphs. The observed pattern of co-variation of floral features between morphs suggested that flower base shape would be an additionally ancillary trait linked to the stigma-anther polymorphism in the species.

Abstract: las investigaciones básicas y clínicas realizadas en los últimos a?os sobre las células madre y sus posibilidades terapéuticas, son en la actualidad uno de los temas más excitantes de la medicina contemporánea. ya se han obtenido importantes avances en el estudio y aplicación de las células madre adultas que muestran notables ventajas sobre las embrionarias, pues su manipulación resulta más simple, económica y se pueden obtener del propio individuo que va a ser tratado. para la introducción en cuba de la terapia celular regenerativa, en el instituto de hematología e inmunología se seleccionaron como fuentes celulares las células madre adultas derivadas de la médula ósea y las movilizadas a la sangre periférica. para facilitar la extensión del tratamiento a otros centros hospitalarios, se estandarizó una técnica para la movilización de las células madre hematopoyéticas a la sangre periférica, mediante un factor estimulador de colonias de granulocitos (filgrastim, de producción nacional) y se desarrolló un método simple, económico y también más tolerable para los enfermos. de esta forma, se ha extendido la terapia celular a 6 provincias cubanas y hasta abril del a?o 2009 se habían tratado 563 casos con trasplante de células madre adultas autólogas, de los cuales el 81,7 % corresponde a pacientes con enfermedades angiológicas, en los que se ha logrado disminuir significativamente la indicación de amputaciones mayores. también los resultados han sido muy prometedores en las lesiones óseas y procesos periodontales, entre otras enfermedades tratadas. los resultados obtenidos hasta el momento se pueden considerar como un nuevo logro de la ciencia revolucionaria y de nuestros sistemas nacionales de salud y de ciencia y técnica. el método empleado es un proceder económico y factible para instituciones con recursos limitados.
El desconocimiento de la doctrina constitucional frente al principio de legalidad que opera en derecho disciplinario
María Lourdes Ramírez Torrado,Nelson Hernández Meza
Revista Opinión Jurídica , 2011,
Abstract: El valor que ostenta la doctrina constitucional dentro del sistema de fuentes, en el derecho colombiano es incuestionable. No obstante, el hecho de considerar su desconocimiento como falta disciplinaria vuelve indispensable el análisis de esta posición a la luz del principio de legalidad que rige en materia sancionadora administrativa. Así, la finalidad de la investigación es la determinar la legalidad, o no, de la sanción disciplinaria impuesta por el desconocimiento de la doctrina constitucional, para, de este modo, ofrecer una posible respuesta a la realidad jurídica que se nos impone.

Abstract: Four “cuajada” type fresh cheeses were evaluated by two trained panels in different regions from Oaxaca in Mexico (Instituto Tecnológico de Comitancillo (ITC) and Universidad del Mar (UMAR)). Each panel was integrated by six judges. Analysis of variance (ANOVA) in conjunction with principal component analysis (PCA) and the Rv coefficient were used to identify similarities and consensus among trained judges and panels. The ANOVA results revealed that the judges from ITC performed significantly better (P < 0.05) in discrimination and repetitivity, while both panels showed a similar effect in discrimination. The PCA determined some similarities in the position of cheeses in the sensory space, while Rv revealed that judges and panels were consensual. In conclusion, statistical resources determined that both panels were discriminating and that similarities in the positioning of cheeses in the sensory space were found.

Abstract: Visceral leishmaniasis (VL) in Latin America and particularly in Venezuela, is a protozoan infection that in recent decades has shown changes in the epidemiological pattern, initially rural to activating urban foci, resulting in the emergence of a public health problem in the periphery of large cities. In the Parasitology Department, Carabobo University, in 2005, was diagnosed a case of human visceral leishmaniasis in a 2-year old child, resident of Barrio Los Próceres, located in the Municipality Naguanagua, Carabobo State. This was the first reported case of VL in this community. From this finding we carried out a seroepidemiological study in human and canine population of this community in an attempt to characterize it as an urban focus of VL. An epidemiological survey was conducted and blood samples were taken from the human and canine population living in an area of 200 m. of the index case, in order to detect anti-leishmania antibodies using the ELISA-rK39 test. The seroprevalence obtained for human was 5.96% (9 / 151), and for dogs 24.24% (8 / 33). 55.55% of seropositive humans were between 0-13 years old. No evidence of association between seropositivity and assessed epidemiological variables such as educational level, occupation, length of residence in the town of origin, from other communities and the presence of dogs. Most of the seropositive dogs were over 2 years of age and in an asymptomatic condition. Results suggest the presence of a new recent focus of urban LV of in the studied area
