Derechos y deberes. El horizonte de la responsabilidad
2013
El artículo recorre aquellos acontecimientos y textos del siglo XX más reveladores a la hora de abordar la relación entre derechos y deberes, proponiendo una lectura renovada de la noción de responsabilidad humana. La reflexión sobre las carencias del individualismo y del estatalismo, latentes en la cultura jurídicopolítica contemporánea, no pretende relativizar el papel de los derechos sino tratar de reforzarlo a través de un discurso permeable a otras formulaciones de las exigencias de justicia y a otras concepciones del mundo, con el objetivo de fortalecer la conciencia cívica, el tejido social relacional, la asunción responsable de las propias obligaciones y una idea de universalidad má…
Confidence Interval or P-Value?: Part 4 of a Series on Evaluation of Scientific Publications
2009
An understanding of p-values and confidence intervals is necessary for the evaluation of scientific articles. This article will inform the reader of the meaning and interpretation of these two statistical concepts.The uses of these two statistical concepts and the differences between them are discussed on the basis of a selective literature search concerning the methods employed in scientific articles.P-values in scientific studies are used to determine whether a null hypothesis formulated before the performance of the study is to be accepted or rejected. In exploratory studies, p-values enable the recognition of any statistically noteworthy findings. Confidence intervals provide informatio…
Predicting who fails to meet the physical activity guideline in pregnancy: a prospective study of objectively recorded physical activity in a populat…
2016
Background A low physical activity (PA) level in pregnancy is associated with several adverse health outcomes. Early identification of pregnant women at risk of physical inactivity could inform strategies to promote PA, but no studies so far have presented attempts to develop prognostic models for low PA in pregnancy. Based on moderate-to-vigorous intensity PA (MVPA) objectively recorded in mid/late pregnancy, our objectives were to describe MVPA levels and compliance with the PA guideline (≥150 MVPA minutes/week), and to develop a prognostic model for non-compliance with the PA guideline. Methods From a multi-ethnic population-based cohort, we analysed data from 555 women with MVPA recorde…

El Mal como problema político : el “paradigma Dostoievski” y el nacimiento de la distopía
2016
Fil: Del Percio, Daniel. Pontificia Universidad Católica Argentina; Argentina Fil: Del Percio, Daniel. Universidad de Palermo. Facultad de Ciencias Sociales. Centro de Investigación en Ciencias Sociales; Argentina Fil: Del Percio, Daniel. Universidad del Salvador; Argentina Resumen: Quizás uno de los aspectos más inquietantes del mal, visto desde la metafísica, es que posee un sorprendente paralelo con el nihilismo. Sobre ambos podemos decir que son problemas que no tienen solución, pero sí historia. Desde esta perspectiva, la literatura nos ofrece una extensísima lista de ejemplos que ilustran esa doble historia, tan complementaria entre sí, al punto de que cada una permite abrir un horizo…

Magnetic resonance imaging of the cirrhotic liver in the era of gadoxetic acid.
2015
Gadoxetic acid improves detection and characterization of focal liver lesions in cirrhotic patients and can estimate liver function in patients undergoing liver resection. The purpose of this article is to describe the optimal gadoxetic acid study protocol for the liver, the unique characteristics of gadoxetic acid, the differences between gadoxetic acid and extra-cellular gadolium chelates, and the differences in phases of enhancement between cirrhotic and normal liver using gadoxetic acid. We also discuss how to obtain and recognize an adequate hepatobiliary phase.
[Role of visual analysis of first-pass contrast-enhanced MRI in reperfused myocardial infarction].
2006
The aim of this work is to evaluate the relationship between improvement of regional myocardial function and visual analysis of contrast-enhanced (CE) MRI in patients after acute myocardial infarction. MRI was performed on 19 patients 1 and 11 weeks after a reperfused acute myocardial infarction. Perfusion data (first-pass images [FPI] and delayed CE images) were acquired after an intravenous bolus of gadolinium-DTPA and visually analyzed using a 17 segment model. Each segment was then classified in 3 groups, according to the presence or absence of FPI and CE patterns at baseline study: group 0: normal-appearing segments; group 1: segments with delayed hyper-enhancement but no early hypo-en…
Litorāles mikrobiotopu ietekme uz Pierīgas brūnūdens ezeru makrozoobentosa sabiedrībām
2019
Maģistra darba “Litorāles mikrobiotopu ietekme uz Pierīgas brūnūdens ezeru makrozoobentosa sabiedrībām” izstrāde un materiālu ievākšana notika (no 17.07.17. līdz 25.05.18.) četros Garkalnes novada ezeros – Līņezerā, Piekūnītī, Maku ezerā un Lielajā Jūgezerā. Analizējot iegūtos rezultātus var secināt, ka zoobentosa organismi visvairāk piesaistīti mikrobiotopiem ar ūdensaugiem un dūņainu grunti. Pārējos mikrobiotopos zoobentosa indivīdu un sugu skaits ir ievērojami mazāks apstiprinot izvirzīto hipotēzi. Ezeru paraugos tika konstatēti 14 dažādi makrozoobentosa taksoni. Visbiežāk pārstāvētās kārtas - vaboles un blaktis. Visi pētāmie ezeri pieskaitāmi brūnūdens ezeru tipam, augu sugu, grunts vei…
The role of red yeast rice (RYR) supplementation in plasma cholesterol control: A review and expert opinion.
2019
1. Preamble : Hypercholesterolemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD) [1]. Increased levels of low density lipoprotein cholesterol (LDL-C) are associated with an increased risk of coronary heart disease (CHD) and many clinical trials have shown that reducing LDL-C levels significantly reduced the CHD and CVD risk [[2], [3], [4], [5]]. Thus LDL-C-lowering is the main approach for the management of cardiovascular disease. Current guidelines suggest LDL-C levels targets based on the individual CV risk; such targets can be achieved by several means, which include both lifestyle changes and pharmacological approaches [6], with statins being the cornerstone …
