Evaluación morfológica y morfométrica de neuroimágenes retinianas y cerebrales como factor pronóstico de la función visual en pacientes con esclerosi…
2013
El propósito de esta tesis doctoral es estudiar la proporción de pérdida neurológica en el tiempo a nivel cerebral y retiniano en relación con la deficiencia sensorial y motora en pacientes diagnosticados de esclerosis múltiple. La muestra está constituida por 35 pacientes clasificados en tres grupos en función del subtipo de enfermedad (síndromes clínicos aislados, formas remitentes-recurrentes y formas progresivas) diagnosticados de esclerosis múltiple según los criterios de McDonald, aunque a efectos del análisis estadístico, las unidades de observación fueron los 70 ojos correspondientes. Se recopiló información mediante la anamnesis y revisión de la historia clínica de los pacientes re…

Into the wild of long non-coding RNA in gastrointestinal stromal tumors (GISTs) to explore new prognostic/predictive biomarkers
2015
Background: Long Non-coding RNAs (lncRNA) are emerging as essential regulators of genetic and epigenetic networks, and their deregulation may underlie complex diseases, such as carcinogenesis. Several studies have described lncRNAs alterations in patients with solid tumors. In particular, in Gastrointestinal Stromal Tumors (GIST), upregulation of HOTAIR has been associated with aggressiveness, metastasis, and poor patients’ survival. In order to gain more detailed insight on the molecular role of lncRNAs in GIST, we analyzed in vivo the expression levels of lncRNAs H19 and MALAT1 in surgically resected patients. Material and Methods: The expression of the lnc-RNAs H19 and MALAT1 was evaluat…
Intestinal conversion of linoleic acid to arachidonic acid in the rat
1993
Abstract The arachidonic acid (C20:4, n-6) appearing in intestinal lymph during linoleic acid (C18:2, n-6) absorption may originate from enterocyte synthesis or from the liver either after secretion in biliary phospholipids at the same time dietary linoleic acid absorption occurs or via plasma. The radioactivity measured in the total bile collected during the 6 hours of linoleic acid absorption is too small to explain hepatic origin of the C20:4 detected by high performance liquid chromatography analysis of labeled fatty acids recovered in the lymph, in the intestinal mucosa, and the intestinal wall at the peak of linoleic acid intestinal absorption. This study confirms the probability that…
Intestinal Trematode Infections
2014
Intestinal trematodes are among the most common types of parasitic worms. About 76 species belonging to 14 families have been recorded infecting humans. Infection commonly occurs when humans eat raw or undercooked foods that contain the infective metacercariae. These parasites are diverse in regard to their morphology, geographical distribution and life cycle, which make it difficult to study the parasitic diseases that they cause. Many of these intestinal trematodes have been considered as endemic parasites in the past. However, the geographical limits and the population at risk are currently expanding and changing in relation to factors such as growing international markets, improved tran…
Integrated analytical methodologies for the study of corrosion processes in archaeological bronzes
2011
Abstract The investigations on structure and micro-chemical composition of archaeological metal alloys are needed in archaeometry. The aim of this study is devoted both to acquire information about their provenance and production technology, and to improve our understanding about the corrosion processes. In this paper we present the study of the corrosion phenomena of bronze samples, laboratory-made according to binary, ternary and quaternary alloys typical of Roman archaeometallurgical production through an integrated methodology based on the use of non or micro invasive physical techniques. Among the analysed samples, two were artificially aged through burial in the archaeological site of…
In vitro fusion of phagosomes with different endocytic organelles from J774 macrophages.
1998
We describe novel biochemical and electron microscopy assays to investigate in vitro fusion of latex bead phagosomes with three different endocytic organelle fractions from J774 macrophages. After formation, early phagosomes fuse avidly with early and late endosomes and for a longer period of time with lysosomes, but they subsequently become fusion-incompetent. The fusion of early, but not late, phagosomes with all three endocytic fractions could be significantly stimulated by Rab5. In contrast to other cell types investigated, this Rab is uniquely enriched on both early and late endosomes in J774 macrophages. Moreover, exogenous Rab5 stimulates homotypic fusion between both sets of organel…
Biowaiver Monographs for Immediate-Release Solid Oral Dosage Forms: Enalapril
2018
Literature data relevant to the decision to allow a waiver of in vivo bioequivalence testing for the marketing authorization of immediate-release, solid oral dosage forms containing enalapril maleate are reviewed. Enalapril, a prodrug, is hydrolyzed by carboxylesterases to the active angiotensin-converting enzyme inhibitor enalaprilat. Enalapril as the maleate salt is shown to be highly soluble, but only 60%-70% of an orally administered dose of enalapril is absorbed from the gastrointestinal tract into the enterocytes. Consequently, enalapril maleate is a Biopharmaceutics Classification System class III substance. Because in situ conversion of the maleate salt to the sodium salt is sometim…
