Paradiplozoon iraqensis n. sp. (Monogenea: Diplozoinae) from Cyprinion macrostomum (Cyprinidae) in the Tigris River, Iraq
2015
A new species of monogenean diplozoid, Paradiplozoon iraqensis n. sp., from the gills of Cyprinion macrostomum Heckel from the Tigris River in Tikrit, Iraq is described. P. iraqensis n. sp. is distinguished from other species of the genus by the size of plicae on the fore- and hind body, the number of the branches of the intestinal caecum in fore body, intestinal caecum not extending to haptor, the size of the clamps and the morphology of the clamp sclerites, and by the length of the central hooks. Details of the shape and size of eggs, and of the reproductive system and prohaptoral region are provided. The present study raises the number of species of Paradiplozoon recorded in Iraq to 15.
Diagnostic accuracy of the light microscope method to detect the eggs of Cardicola spp. in the gill filaments of the bluefin tuna.
2017
Trematode blood flukes of the genus Cardicola are potentially lethal in bluefin tuna cultures. The present study proposed a new method to detect aporocotylid eggs in tuna gills. Aporocotylid eggs were detected by analysing a pair of gill filaments of five transversal areas of the eight holobranches of one hundred Atlantic bluefin tuna and observed with glycerol and a stereomicroscope with an oblique brightfield. Data were gathered according to holobranches, transversal areas and their combination. Eggs were uniformly distributed among the holobranches, but they had the highest prevalence in the second and fifth transversal areas, which is controversial with respect to previous studies of eg…
A New Species of Ligophorus (Monogenea: Dactylogyridae) from the gills of the Flathead Mullet Mugil cephalus (Teleostei: Mugilidae) from Mexico
2015
AbstractA new monogenean species, Ligophorus yucatanensis n. sp. from the gills of the flathead mullet Mugil cephalus from the Yucatan Peninsula, Mexico, is described. The new species can be differentiated from all other species of Ligophorus by the morphology of the accessory piece of the copulatory organ. Its main lobe is cylindrical, tunnelled expanded distally, slightly bowed with a characteristic membranous opening at level of medial bifurcation of the accessory piece, forming a thick-walled bulbshaped expansion that ends in a round labium. The secondary lobe is spatulate, straight, and shorter than the main lobe. In addition, the new species can be distinguished from other species by …
REDESCRIPTION OF ALLENCOTYLA MCINTOSHI PRICE, 1962 (MONOGENEA), WITH AN EMENDED DIAGNOSIS OF ALLENCOTYLA PRICE, 1962
2003
The original description of the type species of Allencotyla, A. mcintoshi Price, 1962, was based on 5 specimens collected from 1 amberjack Seriola lalandi in Florida. In this study, A. mcintoshi is redescribed based on new specimens collected from juvenile greater amberjacks S. dumerili captured off the Spanish Mediterranean coast and maintained in experimental culture tanks. Except for a slightly smaller size, individuals of S. dumerili were morphologically similar to the type specimens. However, reexamination of the type material and examination of the new specimens revealed the following discrepancies with respect to the original description: (1) the vaginal pore is unarmed and covered w…

High-performance liquid chromatographic study of the regulation of phospholipid metabolism in cultured adrenocortical cells
1994
Abstract A rapid high-performance liquid chromatographic (HPLC) method for the separation of phospholipids was developed for minute samples of total lipids (ca. 200 μg). The method was applied to the study of the phospholipid metabolism in adrenocortical cell cultures. A complete separation of the different cellular phospholipid classes was achieved in 40 min. Good resolution of the phospholipid peaks was obtained, which allowed the collection of each individual class of phospholipids for further analysis of radioactivity and fatty acid composition by gas chromatography. When cells were incubated with [U-14C]glycerol or [U-14C]palmitate the bulk of the radioactivity was found in cellular ph…
Differential expression and glycosylation of proteins in the rat ileal epithelium in response to Echinostoma caproni infection.
2013
Echinostoma caproni (Trematoda: Echinostomatidae) is an intestinal trematode that has been used as experimental model to investigate the factors determining the expulsion of intestinal helminths. We analyze the changes in the protein expression and glycosylation induced by E. caproni in Wistar rat, a host of low compatibility in which the parasites are rapidly rejected. To determine the changes in protein expression, two-dimensional difference gel electrophoresis was employed using protein extracts from the intestine of naïve and infected rats. The patterns of glycosylation were analyzed by lectin blotting. Those spots showing differential expression or glycosylation were analyzed by mass s…
Parasitismo intestinal en población infantil de los departamentos del Pacífico Nicaragüense
2014
Formando parte de los estudios encaminados al conocimiento del parasitismo intestinal en la población infantil nicaragüense, la presente Tesis Doctoral tiene como objetivo básico abordar el parasitismo intestinal en los diferentes Departamentos que conforman la Región Pacífico, excepción hecha del Departamento de Managua. Para ello se ha estudiado coproparasitológicamente un total de 1881 sujetos (939 niños y 942 niñas), de edades comprendidas entre 0 y 15 años, procedentes de los Departamentos de Chinandega, León, Masaya, Carazo, Granada y Rivas. El espectro enteroparasitario ha quedado conformado por un mínimo de 20 especies (13 de protozoos y 7 especies de helmintos). Desde el punto de v…
Estudio ONTARGET. Diseño y objetivos. Sus resultados. ¿Qué cuestiones pendientes resolverán?
2008
En los ultimos anos, el sistema renina-angiotensina-aldosterona (SRAA) ha centrado gran parte de la investigacion en la fisiopatologia cardiovascular. Se han alcanzado profundos conocimientos sobre su regulacion, su papel en la homeostasis de los sistemas cardiovascular y renal y su participacion en gran parte de los procesos patologicos que acontecen en el sistema cardiovascular y en el rinon. La utilizacion de inhibidores de la enzima de conversion de angiotensina (IECA) y de bloquedores selectivos del receptor AT1 de la angiotensina II (ARA-II) reduce la morbilidad y la mortalidad cardiovasculares mas alla de su impacto en los valores de presion arterial. Pese a ello, la morbilidad y la …
