El presente estudio tiene como objetivo determinar las principales patologías que afectan a los caninos atendidos en las Veterinarias de Managua (Soza I y II) ubicadas en el barrio la Fuente y la Colonia 10 de junio, en el periodo de enero 2014 a marzo 2015. La investigación es descriptiva, identificando cada caso mediante análisis del historial clínico, examen clínico y el empleo de exámenes complementarios de laboratorio realizado a los pacientes atendidos durante la fase de campo más los expedientes clínicos de un año en ambas Veterinarias, trabajando con un total de 153 expedientes. Los datos se analizaron a través del llenado de dos listas de cotejo para la identificación de la concurrencia y recurrencia de las patologías presentes en caninos; y los factores que predisponen la presencia de las mismas. Las variables a evaluar fueron: Principales patologías caninas, de lo cual se obtuvo: 31 casos de Anemia Nutricional, 31 casos de Dermatomicosis y 22 casos de Babesiosis. Proporción por patología, obteniendo: Anemia nutricional con un 20%, Dermatomicosis 20%, B abesiosis 15%, Obstrucción intestinal 9%, G astroenteritis 8%, Insuficiencia renal aguda 6%, Sarna 5%, Hepatitis infecciosa 5%, Neumonías 5%, Insuficiencia renal crónica 3%, Parvovirus 2%, Piometra 1% y Rabia 1%. Los Factores que predisponen la presencia de patologías son: Extrínsecos: 1. Clima, obteniendo para las Anemias mayor cantidad de casos para los meses de febrero y septiembre y ausencia en enero; Dermatomicosis: mayor en octubre y ausente en mayo; B abesiosis: mayor noviembre y ausente en enero marzo abril y junio. 2. Manejo: Anemia nutricional (desbalance nutricional, capacidad económica) , Dermatomicosis (mala Higiene del animal y del entorno), Babesiosis (deficiente control ectoparasitario ) ; Intrínseco: 1.Sexo, Anemia nutricional afecto más a machos, Dermatomicosis más hembras positivas y Babesiosis más machos afectados, 2.Edad, Anemia nutricional y Dermatomicosis resultaron más casos positivos en cachorros y babesiosis se atendieron más casos en adultos , 3. Raza, Anemia nutricional afecto más a caninos criollos, Dermatomicosis y Babesiosis se diagnosticaron más casos en caninos con pedigrí. Se concluye que las principales patología que afectan a los caninos son las Anemias nutricionales, Dermatomicosis y Babesiosis; las cuales presentaron una proporción de un 20% para los casos de anemia nutricional y dermatomicosis, y un 15% para babesiosis. Los factores que más influyeron en la presencia de estas patologías fue el mal manejo de la mascota y del entorno, la falta de un buen control zoosanitario, poder adquisitivo del dueño.

[EN] The aims of this work were (i) to evaluate the potential of nanostructured lipid carriers (NLCs) as a tool to 24 enhance the oral bioavailability of poorly soluble compounds using saquinavir (SQV), a BCS class IV drug 25 and P-gp substrate as a model drug, and (ii) to study NLC transport mechanisms across the intestinal barrier. 26 Three different NLC formulations were evaluated. SQV transport across Caco-2 monolayers was enhanced up 27 to 3.5-fold by NLCs compared to SQV suspension. M cells did not enhance the transport of NLCs loaded with 28 SQV. The size and amount of surfactant in the NLCs influenced SQV's permeability, the transcytosis pathway 29 and the efflux of SQV by P-gp. An NLC of size 247 nm and 1.5% (w/v) surfactant content circumvented P-gp 30 efflux and used both caveolae- and clathrin-mediated transcytosis, in contrast to the other NLC formulations, 31 which used only caveolae-mediated transcytosis. By modifying critical physicochemical parameters of the 32 NLC formulation, we were thus able to overcome the P-gp drug efflux and alter the transcytosis mechanism 33 of the nanoparticles. These findings support the use of NLCs approaches for oral delivery of poorly 34 water-soluble P-gp substrates.

Carbohydrates, protein, lipid and crude fibre were found to reduce in amount from the anterior to posterior regions along the gut of Sarotherodon galilaeus collected from Lake Kainji. Different regions of the gut exhibited different absorptive powers and all the compounds were differently absorbed in amount. Different sizes of fish showed different absorptive capacity

Background: The diagnosis of invasive candidiasis is difficult because there are no specific clinical manifestations of the disease and colonization and infection are difficult to distinguish. In the last decade, much effort has been made to develop reliable tests for rapid diagnosis of invasive candidiasis, but none of them have found widespread clinical use. Results: Antibodies against a recombinant N-terminal fragment of the Candida albicans germ tube-specific antigen hyphal wall protein 1 (Hwp1) generated in Escherichia coli were detected by both immunoblotting and ELISA tests in a group of 36 hematological or Intensive Care Unit patients with invasive candidiasis and in a group of 45 control patients at high risk for the mycosis who did not have clinical or microbiological data to document invasive candidiasis. Results were compared with an immunofluorescence test to detect antibodies to C. albicans germ tubes (CAGT). The sensitivity, specificity, positive and negative predictive values of a diagnostic test based on the detection of antibodies against the N-terminal fragment of Hwp1 by immunoblotting were 27.8 %, 95.6 %, 83.3 % and 62.3 %, respectively. Detection of antibodies to the N-terminal fragment of Hwp1 by ELISA increased the sensitivity (88.9 %) and the negative predictive value (90.2 %) but slightly decreased the specificity (82.6 %) and positive predictive values (80 %). The kinetics of antibody response to the N-terminal fragment of Hwp1 by ELISA was very similar to that observed by detecting antibodies to CAGT. Conclusion: An ELISA test to detect antibodies against a recombinant N-terminal fragment of the C. albicans germ tube cell wall antigen Hwp1 allows the diagnosis of invasive candidiasis with similar results to those obtained by detecting antibodies to CAGT but without the need of treating the sera to adsorb the antibodies against the cell wall surface of the blastospore.
