Dysfunctional beliefs about health and illness: a family study

2019

espanolLos modelos cognitivos sobre la hipocondria postulan que las experiencias tempranas con la enfermedad promueven el desarrollo de creencias disfuncionales sobre la enfermedad. Estas creencias pueden permanecer latentes y activarse ante un incidente critico. Los estudios publicados aportan datos que avalan de manera indirecta estos planteamientos. Teniendo en cuenta que en el nucleo familiar primario se comparten experiencias sobre la enfermedad, examinamos la relacion entre las creencias disfuncionales que los progenitores y sus descendientes mantienen sobre la enfermedad y los pensamientos, tales como la intolerancia a la incertidumbre y la sobreestimacion de la amenaza, y las relaci…

Association of parental communication deviance with offspring's psychiatric and thought disorders. A systematic review and meta-analysis.

2013

AbstractElevated number of parental Communication Deviance (CD) has been connected with psychiatric and thought disorders in their offspring. However, no earlier systematic efforts have been made to review this issue. The aim of this study was to survey the existing literature systematically and perform a meta-analysis of this association. A literature search for published and unpublished observational studies on the association of parental Communication Deviance with psychopathology in the offspring was conducted. Multiple electronic databases were searched (from 1960 to 2012) and the reference lists of the resulting publications were scanned. The findings were pooled using random effect m…

Objectives: Emerging evidence suggests that maternal obesity (MO) predisposes offspring to obesity and the recently described non-alcoholic fatty pancreas disease (NAFPD) but involved mechanisms remain unclear. Using a pathophysiologically relevant murine model, we here investigated a role for the biological clock--molecular core circadian genes (CCG) in the generation of NAFPD. Design: Female C57BL6 mice were fed an obesogenic diet (OD) or standard chow (SC) for 6 weeks, prior to pregnancy and throughout gestation and lactation: resulting offspring were subsequently weaned onto either OD (Ob_Ob and Con_Ob) or standard chow (Ob_Con and Con_Con) for 6 months. Biochemical, pro-inflammatory an…

Essential omega-3 fatty acids tune microglial phagocytosis of synaptic elements in the developing brain

2019

SUMMARYOmega-3 fatty acids (n-3 polyunsaturated fatty acids; n-3 PUFAs) are essential for the functional maturation of the brain. Westernization of dietary habits in both developed and developing countries is accompanied by a progressive reduction in dietary intake of n-3 PUFAs. Low maternal intake of n-3 PUFAs has been linked to neurodevelopmental diseases in epidemiological studies, but the mechanisms by which a n-3 PUFA dietary imbalance affects CNS development are poorly understood. Active microglial engulfment of synaptic elements is an important process for normal brain development and altered synapse refinement is a hallmark of several neurodevelopmental disorders. Here, we identify …

Contribution of Asian emissions to upper tropospheric CO over the remote Pacific

2021

Abstract. Upon analysing the global distribution of the highest 2 % of daily CO mixing ratios at 400 hPa derived from the MOPITT satellite instrument for 20 years (2000–2019), we very regularly detect regions with very high CO values (i.e. mixing ratios belonging to the globally highest 2 %) over the remote Northern Hemispheric (NH) Pacific. Such events of elevated CO over the upper tropospheric NH Pacific occur throughout the year with surprisingly high regularity and frequency (70 % of all days during winter, 80 % of all days during spring). During winter, most of these pollution events are detected over the north-eastern and central NH Pacific, during spring over the central NH Pacific, …

Thermomineral waters of Greece: geochemical characterization

Regarding TDS concentrations collected waters can be subdivided into low salinity (up to 1.5 g/L) brackish (up to 20 g/L) and saline (up to 43 g/L). The medium high salinities can be justified by mixing with sea water and/or strong waterrock interaction processes. Isotope composition of O and H ranges from 12.7 to +2.7 ‰ SMOW and from 91 to +12 ‰ SMOW respectively and is generally comprised between the Global Meteoric Water Line and the East Mediterranean Meteoric Water Line. Only few water samples show a positive shift for δ18O possibly related to high temperature waterrock interaction processes.

Moreover the majority of them is found along the coast as well as in islands of the Aegean Sea and thus thermal water is often brackish to saline due to marine intrusion into costal aquifer. In the present study almost 300 thermal and cold mineral water samples were collected along the Hellenic territory with their physicochemical parameters (temperature pH electrical conductivity and Eh) and the amount of bicarbonates (titration with 0.1N HCl) being determined in situ. Additionally gases found either in free or dissolved phase were sampled. Both water and gas samples were analysed at the INGVPa laboratories for major ions (Ion Chromatography) silica (Inductively Coupled Plasma Optical Emission Spectrometry) chemical composition of free and dissolved gases (Gas Chromatography) water isotopes (O and H) and carbon and helium isotopes of free and dissolved gases (Mass Spectrometry). The temperature of the investigated waters ranges from 6.5 to 98°C pH from 1.96 to 11.98 whilst Total Dissolved Solids (TDS) from 0.06 to 43 g/L. Based on the temperature parameter waters can be divided into four groups: i) cold (&lt0.5 913000 μmol/mol) are the prevailing gas species found in the studied sites.

Lideratge prosocial i acció col·lectiva: anàlisi sumari de l'experiència spring

2016

espanolLas revisiones mas recientes sobre liderazgo no convencional ponen de relieve la importancia de la prosocialidad, como rasgo que contribuye a innovar la concepcion del papel y la relacion que promueve el lider y como estructura que fundamenta la orientacion y la profundidad que toma la dinamica de la accion de los grupos, en terminos de empoderamiento e influencia. El analisis que presentamos sobre la modelizacion del liderazgo prosocial a traves de la propuesta teorica y formativa del Laboratorio de Investigacion Prosocial Aplicada –LIPA-NET– se ha llevado a termino en el contexto del Proyecto Alfa III SPRING. Los resultados son alentadores en cuanto ponen de manifiesto que la funci…

In this paper mathematical modeling of a vehicle crash test based on a single-mass is studied. The model under consideration consists of a single-mass coupled with a spring and/or a damper. The parameters for the spring and damper are obtained by analyzing the measured acceleration in the center of gravity of the vehicle during a crash. A model with a nonlinear spring and damper is also proposed and the parameters will be optimized with different damper and spring characteristics and optimization algorithms. The optimization algorithms used are interior-point and firefly algorithm. The objective of this paper is to compare different methods used to establish a simple model of a car crash an…

Optimal Damping Constant Investigation on a Quarter-Car

2013

This paper shows an investigation on optimal damping constant performed in the frequency domain. The optimal damping constant is meant as that value that minimizes the acceleration of all connected bodies characterizing a two degree of freedom system sketching a quarter car. The connected bodies are sprung and unsprung mass respectively for quarter of chassis and tire, this last keeps the contact with the ground and it is connected with the sprung mass through a shock absorber characterized by spring and fluid damper. Optimal damping constant was determined by imposing analytical conditions on the expression of acceleration of two masses. Afterwards, the variation of acceleration and positi…
