NONEQUILIBRIUM PHENOMENA AND METASTABILITY IN MESOSCOPIC AND QUANTUM SYSTEMS
2020
Here we summarize some relevant results related to nonequilibrium phenomena in mesoscopic and quantum systems. A common phenomenon in the dynamics of out-of-equilibrium systems is the metastability, and the problem of the lifetime of metastable states involves fundamental aspects of nonequilibrium statistical mechanics. Metastability (see Fig. 1) is a signature of a first order phase transition, often characterized by a long-living metastable state. In particular, the stability of a metastable state can be enhanced by Gaussian and non-Gaussian noise sources. This counterintuitive effect has been found in different physical areas, ranging from spintronics, aggregation kinetics of Brownian pa…
Consequences of analgesics use in early pregnancy: Results of tests on mice.
2019
International audience; Self-medication during pregnancy continues to be an issue in developing countries due topoor medical education. The most commonly used drugs are analgesics, mainlyacetaminophen (paracetamol, APAP) and, to a lesser extent, ketoprofen (KPF). The aim of thestudy was to establish whether there are consequences of accidental use of these two drugsduring early embryogenesis. The experimental study was performed on 30 pregnant whitemice, divided into three groups: a first group to which APAP was administered, a secondgroup to which KPF was administered, and group 3 as a control group. At delivery, the babymice were examined, and after their first parturition, they were take…
Particle models for kinetic equations: an introduction and some rigorous results
2011
We shall give an introduction to the validity problem for kinetic equations and we shall review some convergence theorems concerning the derivation from a microscopic dynamics of systems of partial differential equations describing, at the mesoscopic scale, collections of particles interacting through various (collisions and mean field) type of interaction.
Nuevos desafíos en el análisis de la composición mineral de los alimentos
2017
El ser humano resulta expuesto a numerosas sustancias químicas que se incorporan a la cadena alimentaria, constituyendo la ingesta a través de la dieta una de las principales vías de entrada en el organismo. Entre estas sustancias, destaca el interés del estudio de elementos altamente tóxicos como por ejemplo arsénico (As), berilio (Be), cadmio (Cd), cromo (Cr VI) plomo (Pb), mercurio (Hg) y níquel (Ni); elementos de menor toxicidad como antimonio (Sb), bario (Ba), cesio (Cs), germanio (Ge), paladio (Pd), teluro (Te), talio (Tl); estaño (Sn), titanio (Ti), y vanadio (V) o elementales esenciales como cobalto (Co), cobre (Cu), hierro (Fe), magnesio (Mg), molibdeno (Mo), selenio (Se), cromo (C…

Oral contraceptives in the prevention of endometrioma recurrence: does the different progestins used make a difference?
2013
""The primary aim of the study was to analyze the endometrioma recurrence rate in patients who underwent laparoscopic excision followed by postoperative long-term regimen of oral contraceptives (OCs).. . MATERIALS AND METHODS: 168 patients who underwent a conservative laparoscopic surgery for endometrioma, during the period between September 2009 and August 2010 in three university hospitals were studied. A long-term OCs therapy was offered to all women following surgery. Patients were randomly divided into three groups according to different progestins used (desogestrel, gestodene, dienogest). Women who refused a postoperative hormonal therapy served as control. Follow-up visits and transv…
Motivation for participation in rehab therapy and stress-coping styles in alcohol dependent women and men = Motywacja do udziału w terapii i style ra…
2020
Wprowadzenie: Przedstawiono przegląd literatury z zakresu stylów radzenia sobie ze stresem i motywacji do uczestnictwa w terapii w grupie kobiet i mężczyzn uzależnionych od alkoholu. Wywnioskowano, że dotychczasowe dane empirycznie pozwalają na zaobserwowanie zróżnicowania ze względu na płeć, ale nie umożliwiają stworzenia jednoznacznych modeli w zakresie motywacji i radzenia sobie ze stresem przez kobiety i mężczyzn. Materiał i metody: W badaniu wzięło udział 90 ochotników (33 K i 57 M) w wieku od 22 do 70 lat (M = 43,70; SD = 11,26), uczęszczających na terapię uzależnień (M = 7,97 miesięcy; SD = 5,76) do ośrodka leczenia uzależnień na Górnym Śląsku. Respondenci wypełnili metryczkę, Kwesti…
‘Cos I’m a Survivor’ : Narratives of coping and resilience in recollections of difficult childhood in post-war Finland
2018
In post-war Finland thousands of children experienced poor upbringing, neglect and abuse, and had to deal with their experiences without social support from adults. In this article we study how difficult and bitter experiences related to childhood crises are remembered, reinterpreted and reframed in later life and in contemporary Finland. As research material we use both oral and written reminiscences of childhood in the post-war years collected in the period 2014–2016. We argue that in the recollections of difficult childhood coping and resilience emerge as major narrative themes. Although informants in their childhood were forced to suffer in silence, they remember themselves as being res…
Psychological variables and temporomandibular disorders: distress, coping, and personality.
2004
Abstract Objective This study analyzes the psychological variables of distress, personality, and coping that are related to the diagnosis based on the Research Diagnostic Criteria for temporomandibular disorder. Study design An age and sex-matched controlled study conducted with a convenience sample (n = 89) in a tertiary care facility. Results The MANCOVA between the muscular (n = 47), articular (n = 42), and control groups (n = 100) showed that the muscular group differed from the control group, obtaining higher levels of distress, anxiety, and depression, and minor use of positive reinterpretation and humor as coping strategies; the articular group also showed higher distress, less posit…
Condromatosis sinovial de la articulación temporomandibular: Estudio clínico, radiológico e histológico
2005
La condromatosis sinovial (CS) es una metaplasia cartilaginosa de los remanentes mesenquimales del tejido sinovial de las articulaciones. Se caracteriza por la formación de nódulos cartilaginosos en la sinovial y en la cavidad articular (cuerpos libres). La CS afecta sobre todo a grandes articulaciones sinoviales como la rodilla o el codo, siendo rara su aparición en la ATM, en donde tan solo 75 casos han sido publicados. Los síntomas predominantes son dolor, inflamación, limitación de los movimientos mandibulares y crepitación. Los métodos diagnósticos incluyen la ortopantomografía (OPG), la TC, la RM y la artroscopia de ATM. Presentamos un nuevo caso de CS unilateral de ATM, incluyendo la…
