Components of the mediterranean-type food pattern and serum inflammatory markers among patients at high risk for cardiovascular disease
2007
Components of the Mediterranean-type food pattern and serum inflammatory markers among patients at high risk for cardiovascular disease. OBJECTIVE: To evaluate associations between components of the Mediterranean diet and circulating markers of inflammation in a large cohort of asymptomatic subjects at high risk for cardiovascular disease. SUBJECTS/METHODS: A total of 339 men and 433 women aged between 55 and 80 years at high cardiovascular risk because of presence of diabetes or at least three classical cardiovascular risk factors, food consumption was determined by a semi-quantitative food frequency questionnaire. Serum concentrations of high-sensitivity C-reactive protein (CRP) were meas…
Polymorphisms cyclooxygenase-2 -765G>C and interleukin-6 -174G>C are associated with serum inflammation markers in a high cardiovascular risk populat…
2009
Inflammation is involved in cardiovascular diseases. Some studies have found that the Mediterranean diet (MD) can reduce serum concentrations of inflammation markers. However, none of these studies have analyzed the influence of genetic variability in such a response. Our objective was to study the effect of the -765G>C polymorphism in the cyclooxygenase-2 (COX-2) gene and the -174G>C polymorphism in the interleukin-6 (IL-6) gene on serum concentrations of IL-6, C-reactive protein, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule-1 as well as their influence on the response to a nutritional intervention with MD. An intervention study in a high cardiovascular ri…
Vitamin D Deficiency: The Missing Etiological Factor in the Development of Juvenile Osteochondrosis Dissecans?
2016
BACKGROUND Vitamin D deficiency can result in rickets and hypocalcemia during infant and childhood growth. There is an increasing interest in the role of vitamin D with regards to childhood bone health. Osteochondrosis dissecans (OD) is a common disease affecting different joints. To date, the exact etiology of OD still remains unclear. The aim of this study was to evaluate a possible association of vitamin D deficiency and juvenile OD. METHODS A retrospective chart review of the years 2010 to 2015 of all orthopaedic patients with an initial diagnosis of juvenile OD admitted to undergo operative treatment of the OD was performed. Patient demographics, medical history, information on sports …
The convergence of the perturbed Newton method and its application for ill-conditioned problems
2011
Abstract Iterative methods, such as Newton’s, behave poorly when solving ill-conditioned problems: they become slow (first order), and decrease their accuracy. In this paper we analyze deeply and widely the convergence of a modified Newton method, which we call perturbed Newton, in order to overcome the usual disadvantages Newton’s one presents. The basic point of this method is the dependence of a parameter affording a degree of freedom that introduces regularization. Choices for that parameter are proposed. The theoretical analysis will be illustrated through examples.
Shining castles and humans of metal/floral appearance ? metaphorical language in the Palaiologan romances Kallimachos and Velthandros
2019
About eight centuries after Heliodorus, the Greek novel resurfaced in the twelfth century, in Komnenian Byzantium, and again two centuries later under the Palaiologan dynasty. This latter literary revival was due to the political stability of the imperial Byzantine government, which promoted cultural production, rhetorical education, and patronage networks. Kallimachos and Velthandros, two Palaiologan romances presented as court literature, combine ancient and medieval tropes with rhetorical artistry to blur the boundaries between the artificial and the natural. Castles and objects made of precious metals thus resemble living, natural spaces, and human characters are portrayed in metallurgi…
Drying kinetics of thyme
2012
Los objetivos del trabajo fueran estudiar la cinética del secado de tomillo con posterior ajuste de diferentes modelos matemáticos a los datos experimentales y determinar los valores de la difusividad efectiva y energía de activación. Para el desarrollo del experimento de secado fueran utilizadas las temperaturas 30, 40, 50, 60 y 70 oC. El diseño experimental fue de bloques completamente aleatorizados, con tres repeticiones. Para el ajuste de los modelos matemáticos a los datos experimentales fue realizado el análisis de regresión no lineal, por el método Simplex-Quasi-Newton. Los resultados mostraron que el modelo matemático de Page obtuve un mejor ajuste a los datos experimentales, los va…
Teorie implicite sull’intelligenza e motivazione intrinseca
2016
In questo articolo si mette a fuoco come per stimolare l’apprendimento e sviluppare l’autonomia degli alunni sia fondamentale, fin dalla scuola primaria, riconoscere l’importanza delle teorie implicite sull’intelligenza e il ruolo essenziale che ricoprono nello sviluppo della motivazione intrinseca. Un fattore che influenza la motivazione e, di conseguenza, il successo scolastico è il tipo di concezione dell’intelligenza posseduto dagli alunni che sviluppano approcci differenti all’apprendimento in relazione ad essa. Il possesso da parte di un alunno di teorie implicite entitarie o incrementali è cruciale nell’adeguata o nella mancata elaborazione di successi e fallimenti, nonché predittivo…
A Hybrid AHP Approach and GIS-Based Methods as Fundamental Tools in the SECAP’s Decision-Making Process
2023
Adapting to climate change and mitigating its impacts are the main challenges for cities today. One objective that the European Commission has set in recent decades is reducing climate change inaction, and several political actions have been implemented. Among these actions, the Covenant of Mayors led to the development and adoption of Sustainable Energy and Climate Action Plans (SECAPs) by many cities worldwide. A challenge that local authorities must face during the development of a SECAP is the identification of the policies to be included in the plan. This paper presents a case study to show the validity of using a hybrid analytic hierarchy process (AHP) approach and various geographic …
Del Sistema Europeo Común de Asilo al nuevo “Pacto sobre Migración y Asilo”: ¿Una nueva política de protección internacional es posible?
2021
Si bien la norma madre en materia de asilo es la Convención de Ginebra de 1951 y seguidamente el Protocolo de New York de 1967, éstos instrumentos internacionales necesitan de la voluntad política y una norma nacional para que sean efectivizados a nivel interno. Hasta la fecha, más de 145 países los han ratificado y seguidamente promulgaron sus propias leyes nacionales de asilo. Sin embargo, la práctica muestra que según el Estado del que se trate, el asilo, tendrá en él un tratamiento más proteccionista o restrictivo, pero nunca uniforme. En ese sentido, dentro del contexto de la Unión Europea (UE), desde 1999 se ha intentado atender el espíritu de la Convención de Ginebra a través de un S…
Nātrija un kālija sāļu salīdzinošā ietekme uz dažādu sugu augu augšanu un jonu uzkrāšanos
2019
Sāļums ir viens no abiotiskajiem faktoriem, kam ir būtiska ietekme uz jūras piekrastes, sāls mitrāju, pasaules sauso reģionu augu augšanu un attīstību. Augu sugām, kas dabiski izplatījušās biotopos ar augstu vides sāļumu, raksturīga ievērojami lielāka sāls izturība nekā sugām, kas izplatījušās biotopos ar zemu sāļu koncentrāciju, tai skaitā kultūraugiem. NaCl ir izplatītākais sāļu veids, tāpēc tā ietekme uz augiem tiek visvairāk pētīta. Par citu sāļu veidu ietekmi un to salīdzinājumu ar NaCl ir samērā neliels skaits pētījumu. Uzskata, ka Na+ izraisītais osmotiskais stress, jonu toksiskums un jonu disbalanss izraisa dažādu fizioloģisko procesu neoptimālu norisi augā, kā rezultātā novēro sāļu…
