Revista Colombiana de Ciencias Pecuarias , 2010,
Abstract: La colecistitis es una patología inflamatoria de la vesícula biliar (VB) y la obstrucción e infección biliar serían las causas principales de su presentación. El diagnóstico es difícil, porque tanto los signos clínicos como las anormalidades clínico-patológicas son poco específicas, por lo que la ecografía resulta una modalidad diagnóstica importante, ya que la visualización ecográfica de espesamiento de la pared de la VB o de bilis hiperecogénica induce a la sospecha de colecistitis. El cultivo y antibiograma biliar permiten definir el tratamiento antibiótico específico. Se describe un caso clínico donde se destaca la importancia de la ecografía en el diagnóstico de la colecistitis canina. A colecistite é uma patologia inflamatória da vesícula biliar e a obstru o e infec o seriam as causas principais de sua apresenta o. O diagnostico é difícil, porque os signos clínicos e as anormalidades clínico-patológicas s o específicas, pelo que o ultra-som resulta em uma modalidade diagnóstica importante, porque a visualiza o no ultra-som do espacejamento da parede da vesícula biliar ou do bílis hiperecogénica induz à suspeita de colecistite. O cultivo e antibiograma biliar permitiram definir o tratamento antibiótico específico. Descreve-se um caso clínico onde destaca-se a importancia do ultra-som no diagnóstico da colecistite canina.

Abstract: Se estudiaron 71 pacientes de los dos sexos, con edades comprendidas entre los 60 y 75 a os, a quienes se les diagnosticó da o carotídeo extracraneal, pero se mantenían asintomáticos desde el punto de vista neurológico y cardiovascular. A todos se les realizó ecodoppler carotídeo a color de alta resolución y quedaron agrupados en 2 categorías, según da o vascular: 30 pacientes con engrosamiento íntima media > 1,1 mm y 41 con estenosis, además, un grupo control de 30 sujetos con factores de riesgo vascular sin lesión carotídea. A todos se les realizó electrocardiograma y prueba ergométrica para definir diagnóstico de cardiopatía isquémica silente. En relación con este medio diagnóstico, se realizaron modificaciones propias para el anciano, incluyendo recomendaciones de acondicionamiento y medidas preventivas para cualquier complicación. Además, se establecieron contraindicaciones específicas, criterios clínicos y electrocardiográficos de positividad y severidad. Las variables se codificaron en una base de datos computarizada, se realizaron tablas de contingencia (de doble entrada); para las variables cualitativas se empleó el test Chi2 para evaluar asociación entre las variables de interés, y para las cuantitativas, el t Student para comparar los promedios en las variables analizadas. Los resultados se consideraron significativos cuando la probabilidad de asociación de los tests fue < 0,05. De los 101 pacientes que constituyeron la muestra, la distribución por sexo fue de 73 femeninos y 28 masculinos. El tiempo de acción de los factores de riesgo vascular mostró íntima relación con el da o carotídeo, fundamentalmente el hábito de fumar (38,2 a os como promedio), seguido por la hipertensión arterial (13,8 a os) y por la diabetes mellitus (10,5 a os). En ese mismo orden de frecuencia, se evidenció el comportamiento de la acción de los factores de riesgo sobre las arterias coronarias por medio de la prueba ergométrica. Se demostró la relación coincidente entre el da o carotídeo y coronario; los ancianos con estenosis carotídea fueron los de mayor porcentaje de pruebas ergométricas positivas (57,7 %), le siguió el engrosamiento íntima media (38,5 %), y para el grupo control solo un 3,8 %. 71 patients of both sexes aged 60-75 who were diagnosed extracranial carotid damage, but were asymptomatic from the neurological and cardiovascualr point of view, were studied.

Abstract: INTRODUCCIóN: la leptina tiene un importante papel en la patogenia de la obesidad, al informar al hipotálamo del contenido de grasa corporal y regular la ingesta alimentaria, no obstante, esta hormona constituye un elemental mediador de varias funciones fisiológicas en nuestro organismo. MéTODOS: se realizó una revisión bibliográfica que incluyó un total de 32 documentos de la especialidad de Endocrinología, a fin de describir el mecanismo fisiológico de la leptina y su relación con diversos trastornos neuroendocrinos. RESULTADOS: las concentraciones de leptina son inferiores en el sexo masculino, lo que está en relación con el incremento de testosterona, que ejerce un efecto inhibitorio en su producción. Entre otros de sus efectos fisiológicos, interviene también en la regulación del inicio de la pubertad y participa en la respuesta inflamatoria. CONCLUSIONES: actualmente las posibilidades de tratamiento de la obesidad y otros trastornos de fertilidad con el uso de leptina recombinante están abiertas.

Journal of Veterinary Medicine , 2013, DOI: 10.1155/2013/495975
Abstract: The Dogo Argentino (DA) is the first and only breed from Argentina recognized worldwide. Although its morphologic features have been well established, its normal reproductive parameters are not clearly known. The aim of this study was to determine the main DA bitch reproductive parameters. One hundred and forty-nine surveys were obtained from breeders from Córdoba province, Argentina: one for each intact DA bitch from 1 to 14 years old. The DA bitch reached puberty at an average of 8.93 months. The mean duration of vulval bleeding found in this study was 11.11 days. The clinical signs characteristic for proestrous-estrous were vulval edema (89.93%), bleeding during the time of mating (32.21%), holding the tail to the side (95.30%), and docility during mating (85.91%). DA bitches had a whelping rate of 84%. Out of 299 pregnancies, 89.30% exhibited a normal parturition, 6.69% presented dystocia, 2.68% needed Cesarean section, and 1.34% aborted. In conclusion, the reproductive parameters of the DA bitch are similar to those identified for other large breeds. DA often showed a prolonged vulval bleeding longer than proestrus. Its high whelping rate, its low incidence of dystocia, and its good maternal ability define the DA as a good reproductive breed with normal reproductive functions. 1. Introduction The Dogo Argentino (DA) is so far the only breed from Argentina recognized by the Fédération Cynologique Internationale (1973). Even though it is known as a big-game hunting dog, it is now also used as companion and guard dog. Its morphologic features have been very well established; however, its normal reproductive parameters are not clearly known. This knowledge is essential to achieve a proper reproductive management, to determine the ideal time of mating or artificial insemination, to avoid unwanted pregnancies, to estimate whelping date, and to diagnose many pathologies. Domestic dogs are monoestrous and typically nonseasonal breeders, with large individual and breed-specific variations [1]. They reach puberty variably at 6 to 14 months of age, with means positively correlated with breed size [2]. The average of the interestrous interval is 6 months, it ranges from 4 to 12 months depending on breed, age, and individual [3]. The proestrous duration is highly variable, from 6 to 11 days, with an average of 9 days [4]. This stage is characterized by male attraction, nonreceptive bitches, and vulval bleeding. Pseudopregnancy is a physiological syndrome which may occur during diestrous. Its signs are very similar to those typical of pregnant bitches, such as
Growth of Four Varieties of Barley (Hordeum vulgare L.) in Soils Contaminated with Heavy Metals and Their Effects on Some Physiological Traits  [PDF]
águeda González, M. Carmen Lobo
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.49221
Abstract:

To evaluate the effect of zinc (Zn), cadmium (Cd), and chromium (Cr) on growth and selected physiological traits in barley, a greenhouse trial was performed using four barley varieties that were exposed to different concentration of these metals. The parameters quantified were growth, chlorophyll content, and chlorophyll fluorescence during three phenological stages: flag leaf, anthesis, and grain filling. The metal concentrations in both the plant and soil were also quantified. We determined that the varieties studied were more tolerant to Zn and Cd than to Cr. Treatment with Zn did not negatively affect growth, and only high concentrations of Cd decreased growth by approximately 4% to 8%. Plants treated with the highest Cr concentration stopped growing at the flag leaf stage. The amount of metal that accumulated in the plant increased with increasing metal concentration, and the highest amount of accumulated metal was recorded in the root and shoot. Both the plant height and dry weight were higher in the CB502 variety plants, followed by the Reinette, Pedrezuela, and Plaisant varieties. The same trend was observed for the chlorophyll content and fluorescence, with a significant correlation between the growth parameters and chlorophyll content (p < 0.001). Thus, we determined that barley has variability in the studied traits.

Abstract: En la clarificación del agua potable se utiliza sulfato de aluminio para remover materia coloidal y sustancias orgánicas, mejorando la calidad del agua. Elevadas concentraciones de aluminio residual en el agua potable tienen implicaciones en la salud humana, siendo necesario el desarrollo de coagulantes alternativos, ambientalmente aceptables para reemplazar los productos químicos. En esta investigación se estudió el exudado gomoso de Samanea saman como coagulante natural, estableciendo su dosis óptima mediante la prueba de jarro y determinando los parámetros: turbidez, color, pH, alcalinidad total, número más probable y conteo de heterótrofos, usando agua turbia sintética inoculada con un cultivo puro de Escherichia coli y solución de coagulante en dosis de 10-500 mg/L, con valores de turbidez inicial entre 10-100 NTU. La dosis óptima del coagulante resultó entre 10-25 mg/L, obteniendo disminuciones significativas en los valores de turbidez (1NTU) y color (5 UC), los valores de pH y alcalinidad total no presentaron variaciones significativas, los coliformes fecales y totales tuvieron remociones significativas (99,7% y 99,8% respectivamente) y el conteo de heterótrofos de observó con 0 UFC. Los parámetros evaluados cumplen con los estándares establecidos para garantizar la calidad del agua para consumo humano, usando el exudado gomoso de Samanea saman, demostrando la eficiencia de este coagulante natural. For the clarification of drinking water aluminium sulphate is used to remove colloids and organic substances to improve the water quality. High concentrations of residual aluminium in the drinkable water can have implications on human health, thus, it is necessary to develop alternative environmentally acceptable coagulants. The exudates gums from Samanea saman were studied as natural coagulants, establishing optimum dose according to the jar test and determining parameters such as: turbidity, colour, pH, total, alkalinity, MPN and heterotrophic count; using synthetic turbid water inoculated with pure culture of E. Coli and coagulant solution on the volume range of 50 to 500 mg/L. The initial turbidity used was between 10 to 100 NTU. The optimum coagulant dose was found to be between 10 to 25 mg/L, with significant reduction of turbidity and colour, i, e,: 1 NTU for turbidity and 5 U for colour. The pH and total alkalinity did not present significant variations. On the other hand, for fecal coliforms a significant removal of 99.7%, and for total coliforms (99.8%) was found. And finally, the heterotrophic count was observed with 0 UFC. The parameters ev
