Shanghai Fever: Not Only an Asian Disease
2022
Objectives: To describe a case of Shanghai fever disease and to analyze other published reports in non-Asiatic countries, defining clinical characteristics and highlighting that this is not only an Asian disease. Study design: A computerized search without language restriction was conducted using PubMed and Scopus; all references listed were hand-searched to identify any other relevant literature. An article was considered eligible for inclusion in the systematic review if it reported cases with Shanghai fever described in non-Asiatic countries. Our case was also included in the analysis. Results: Ten articles reporting 10 cases of Shanghai fever disease were considered. Fever, diarrhea and…
El embargo preventivo en Bolivia. En especial, frente a los derechos sucesorios y gananciales
2020
La tesis doctoral tiene como objeto de estudio al embargo preventivo. La importancia de su estudio radica en que trata de la medida cautelar por excelencia, por cuanto constituye el fundamento para la existencia de otras medidas cautelares más intensas como el secuestro judicial, la prohibición de innovar, la inhibición de bienes, entre otras. Asimismo, el embargo preventivo destaca por su carácter versátil pues no solo tutela derechos personales o de crédito, sino también aquellos de naturaleza real en la que el interés de los justiciables recae en bienes determinados sobre los cuales alegan la existencia de un derecho cierto. En la primera parte de la tesis doctoral se analizan los elemen…
Locust neuropeptides stimulating sex pheromone production in female European corn borer moth, Ostrinia nubilalis
1990
Abstract The presence of a pheromonotropically active hormone (PBAN-like substance) from locust organs, ( Locusta migratoria ) has been demonstrated. Extracts of brain, corpora cardiaca, corpora allata, suboesophageal ganglia and thoracic ganglia of L. migratoria caused highly pheromonotropic responses in decapitated females of the European corn borer moth ( Ostrinia nubilalis ). The highest activity per unit weight of tissue was found in the corpora cardiaca and corpora allata of the locust followed by the brain plus suboesophageal ganglion of O. nubilalis . Following 8 days of disconnection, separating the corpora allata from the corpora cardiaca and suboesophageal ganglion, the pheromono…
Trigeminal innervation of the mammalian pineal gland.
1999
There is evidence that the trigeminal (Gasserian) ganglia innervate the mamma- lian pineal gland and serve in its regulation in addition to the sympathetic and cholinergic as well as further influences. By means of immunohistochemical methods, previous studies demonstrated fibers containing calcitonin gene-related peptide (CGRP-LI) or substance P (SP) in the superficial pineal of various mammalian species. In addition, SP and the related tachykinin, neurokinin A, were detected by radioimmunoassay and HPLC, respectively, in the rat and human pineal gland. In the present study, retrograde neuronal tracing upon injection of a tracer substance into the superfical pineal gland of rats was used i…
Memory for time intervals is impaired in left hemi-Parkinson patients.
2004
The basal ganglia have been proposed as one of the neural correlates of timekeeping functions. Both encoding and memory retrieval components for time perception are impaired in Parkinson's disease (PD). The aim of our study was to investigate in hemi-Parkinsonian patients the existence of a specific alteration in memory for time depending on the affected side, to better understand the contribution of the left or right basal ganglia circuits in different components of time perception. Right and left hemi-PD patients performed a time reproduction task in which they were required to reproduce in the same session short (5 s) and long (15 s) time intervals, in off- and on-therapy condition. Whil…
Análisis cuantitativa, mediante OCT y Angio-OCT, del grosor coroideo y flujo vascular retiniano y su relación con la capa de fibras nerviosas y célul…
2021
El objetivo principal fue evaluar si existen cambios vasculares, en el grosor coroideo o en la densidad vascular macular, en pacientes con esclerosis múltiple (EM) respecto a controles sanos. Los objetivos secundarios fueron: determinar si existen diferencias vasculares basales según el grado de discapacidad; estudiar si los cambios vasculares se correlacionan con las diferencias de espesor de las capas de fibras nerviosas peripapilares (RNFLno), maculares (RNFLmac) y células ganglionares (GCL);analizar si a lo largo de un año existen cambios vasculares así como cambios anatómicos en los pacientes con EM;comparar el grosor coroideo y la densidad vascular entre pacientes con o sin presencia …
Par reducētajiem Rikarta gredzeniem
2016
Šī darba mērķis ir pētīt reducēto Rikarta gredzenu aksiomātiku, struktūru un dabisko (jeb Eibiena) sakārtojumu tajos. Rakstā [2] Rikarta gredzenos tika ieviestas fokālās operācijas. Pierādīju, ka fokāli Rikarta gredzeni, tas ir, Rikarta gredzeni, kuru signatūrā ietilpst fokālas operācijas, veido varietāti. Arī reducēto fokālo gredzenu klase izrādās varietāte. Pētīju arī greizo gandrīzrežģi, ko iegūst no reducēta Rikarta gredzena, definējot tajā greizo šķelšanas operāciju no [3]. Eibiena sakartojums sakrīt ar šī greizā gandrīzrežģa dabisko sakārtojumu. Aplūkoju stingro pusgrupu pusrežģi, ko var šādā gredzenā konstruēt, un pierādīju, ka katrs reducēts Rikarta gredzens kā greizs gandrīzrežģis …

24S-hydroxycholesterol and cholesterol-24S-hydroxylase (CYP46A1) in the retina: from cholesterol homeostasis to pathophysiology of glaucoma.
2011
http://www.sciencedirect.com/; International audience; Free cholesterol is the predominant form of cholesterol in the neural retina. The vertebrate neural retina exhibits its own capacity to synthesize cholesterol and meets its demand also by taking it from the circulation. Defects in cholesterol synthesis and trafficking in the neural retina has detrimental consequences on its structure and function, highlighting the crucial importance of maintaining cholesterol homeostasis in the retina. Our purpose was to give a review on the functioning of the retina, the role of cholesterol and cholesterol metabolism therein, with special emphasis on cholesterol-24S-hydroxylase (CYP46A1). Similar to th…
In vivo consequences of cholesterol-24s-hydroxylase (CYP46A1) inhibition by voriconazole on cholesterol homeostasis and function in the rat retina
2011
Cholesterol 24S-hydroxylase (CYP46A1) converts cholesterol into 24S-hydroxycholesterol in neurons and participates in cholesterol homeostasis in the central nervous system, including the retina. We aimed to evaluate the consequences of CYP46A1 inhibition by voriconazole on cholesterol homeostasis and function in the retina. Rats received daily intraperitoneal injections of voriconazole (60mg/kg), minocycline (22mg/kg), voriconazole plus minocycline, or vehicle during five consecutive days. The rats were submitted to electroretinography to monitor retinal functionality. Cholesterol and 24S-hydroxycholesterol were measured in plasma, brain and retina by gas chromatography-mass spectrometry. T…
