A Dual Role for Hyperbaric Oxygen in Stroke Neuroprotection: Preconditioning of the Brain and Stem Cells
2018
Stroke continues to be an extremely prevalent disease and poses a great challenge in developing safe and effective therapeutic options. Hyperbaric oxygen therapy (HBOT) has demonstrated significant pre-clinical effectiveness for the treatment of acute ischemic stroke, and limited potential in treating chronic neurological deficits. Reported benefits include reductions in oxidative stress, inflammation, neural apoptosis, and improved physiological metrics such as edema and oxygen perfusion, all of which contribute to improved functional recovery. This pre-clinical evidence has failed to translate into an effective evidence-based therapy, however, due in large part to significant inconsistenc…
Data from: The oxidative cost of reproduction depends on early development oxidative stress and sex in a bird species
2016
In the early 2000’s, a new component of the cost of reproduction was proposed: oxidative stress. Since then the oxidative cost of reproduction hypothesis has, however, received mixed support. Different arguments have been provided to explain this. Among them, the lack of a life history perspective on most experimental tests was suggested. We manipulated the levels of a key intracellular antioxidant (glutathione) in captive zebra finches (Taeniopygia guttata) during a short period of early life and subsequently tested the oxidative cost of reproduction. Birds were allowed to mate freely in an outdoor aviary during several months. We repeatedly enlarged or reduced their broods to increase or …

Environmental Accounting in Colombia from the Perspective of Sustainable Development
2019
Resumen: A partir del interés por identificar los problemas y las perspectivas por las que la academia contable colombiana ha transitado en el campo de la contabilidad ambiental, el presente trabajo pro -pone realizar una revisión literaria conducente a una reflexión sobre las vertientes con las cuales se ha trabajado el tema en Colombia. Para tal efecto, se analizaron 56 textos identificados en 10 revistas colombianas de investigación contable, que fueron publicados en el periodo de 1996 a 2015. Esta revisión se erige a la luz de algunas consideraciones sobre el medio ambiente, la crisis ambiental y el desarrollo sostenible -en sus vertientes fuerte y débil-, que sirven para comprender el …
Project DyAdd : Nonlinguistic theories of dyslexia predict intelligence
2020
Two themes have puzzled the research on developmental and learning disorders for decades. First, some of the risk and protective factors behind developmental challenges are suggested to be shared and some to be specific for a given condition. Second, language-based learning difficulties like dyslexia are suggested to result from or correlate with also nonlinguistic aspects of information processing. In the current study, we investigated how adults with developmental dyslexia and ADHD as well as healthy controls cluster across various dimensions designed to tap the prominent nonlinguistic theories of dyslexia. Participants were 18–55-year-old adults with dyslexia (n = 36), ADHD (n = 22), and…
Crecimiento económico y productividad en Latinoamérica. El proyecto LA-KLEMS
2017
Antecedentes: El objetivo de este artículo es analizar el crecimiento económico, la productividad y sus determinantes en cinco países de América Latina (Argentina, Brasil, Chile, Colombia y México) durante el periodo 1990-2010. Este análisis se aplica tanto a la economía agregada como a nueve sectores de actividad económica. Metodología: Se utiliza una nueva base de datos, LA-KLEMS, que servirá como herramienta fundamental para la investigación empírica y teórica en el área de crecimiento económico y productividad para América Latina. Las variables se organizan en torno a la metodología de contabilidad del crecimiento, que proporciona un marco conceptual claro para el análisis coherente de …

Propolis as a Cariostatic Agent in Lozenges and Impact of Storage Conditions on the Stability of Propolis
2023
Propolis is known as a source of compounds with strong antibacterial activity. Due to the antibacterial effect against streptococci of the oral cavity, it seems to be a useful agent in decreasing the accumulation of dental plaque. It is rich in polyphenols which are responsible for a beneficial impact on the oral microbiota and antibacterial effect. The aim of the study was to evaluate the antibacterial effect of Polish propolis against cariogenic bacteria. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined on cariogenic streptococci related to the occurrence of dental caries. Lozenges based on xylitol, glycerin, gelatin, water, and ethan…
Existence of positive solutions for nonlinear Dirichlet problems with gradient dependence and arbitrary growth
2018
We consider a nonlinear elliptic problem driven by the Dirichlet $p$-Laplacian and a reaction term which depends also on the gradient (convection). No growth condition is imposed on the reaction term $f(z, \cdot,y)$. Using topological tools and the asymptotic analysis of a family of perturbed problems, we prove the existence of a positive smooth solution.
Multidimensional instruments with an integral approach to identify frailty in community-dwelling people: protocol for a systematic psychometric review
2019
IntroductionAn increasing number of investigations highlight the complex nature of frailty; therefore, the use of multidimensional assessment instruments could be useful in clinical decision-making. Frail people are found mainly in the community setting which is why this is the ideal environment for early screening and intervention. For this purpose, it is necessary to have valid, time-effective and easy-to-use frailty assessment instruments. The aim of this review is to critically appraise, compare and summarise the quality of the measurement properties of all multidimensional instruments with an integral approach to identify frailty in community-dwelling people.Methods and analysisMedline…
