The corticotrophin-releasing factor/urocortin system regulates white fat browning in mice through paracrine mechanisms.
2015
Objectives:\ud The corticotrophin-releasing factor (CRF)/urocortin system is expressed in the adipose tissue of mammals, but its functional role in this tissue remains unknown.\ud \ud Methods:\ud Pharmacological manipulation of the activity of CRF receptors, CRF1 and CRF2, was performed in 3T3L1 white pre-adipocytes and T37i brown pre-adipocytes during in vitro differentiation. The expression of genes of the CRF/urocortin system and of markers of white and brown adipocytes was evaluated along with mitochondrial biogenesis and cellular oxygen consumption. Metabolic evaluation of corticosterone-deficient or supplemented Crhr1-null (Crhr1−/−) mice and their wild-type controls was performed alo…

The odour of human milk: Its chemical variability and detection by newborns
2019
International audience; Human milk odour has for long elicited research interest with regard to its function in breastfeeding initiation. The present review aims to provide an overview of the behavioural effects of human milk odour in the human neonate, considering different types of response measures in a feeding or non-feeding context. Further, an overview of the current knowledge of odorant composition and factors influencing milk odour is provided by summarizing results from analytical studies using olfactometry, and addressing changes in milk odour due to storage, lactational stage, and maternal dietary intake of odorous substances. We finally highlight some issues for future research.
Could emotional processing influence pain perception and quality of life in chronic kidney disease and hemodialyzed patients?
2017
Background and Objectives: The incidence of chronic pain is 11-24% in general population, whereas it affects 50% of hemodialyzed subjects and is often secondary to comorbidities, CKD-related complications and certain clinical procedures. Consequently, a better approach in evaluating pain as a “symptom” and in managing it adequately is required for these patients. Methods: 33% of the 300 patients enrolled properly consigned the questionnaires. The mean age of dialyzed patients was 52.2±11.2 years, whereas 54.9±10.7 years was the mean age for CKD patients. Moreover, 53 healthy subjects, ages 20-65, have been included in the study as control group. Specific psycho-diagnostic tests were adminis…
De participació local. Una proposta metodològica desde la investigació-acció-participativa
2018
Citizen participation is an increasingly prevalent term in our society. In the process of deployment in the municipal area, progressively local corporations make efforts to innovate practices and develop experiences of citizen participation in defining policies and public affairs, and allocating budgets. While innovation has been advanced with regard to the tools and mechanisms to be used to promote participation, many of the initiatives and experiences have focused more on the implementation of the vote than in the different social processes inherent in the participation. Moreover, we are faced with the absence of a methodological guide that allows approaching a project or strategic plan o…
Volatile compounds released by disturbed and undisturbed adults of Anchomenus dorsalis (Coleoptera, Carabidae, Platynini) and structure of the pygidi…
2011
Volatile compounds produced by adults of Anchomenus dorsalis under undisturbed and disturbed conditions were investigated with an all-glass aeration apparatus. GC-MS analysis of the crude extracts from undisturbed and disturbed adults highlighted four major volatile compounds, undecane, heneicosane, Z-9 tricosene and tricosane, of which significantly more undecane was released by disturbed adults compared to undisturbed beetles. The pygidial glands of adults of A. dorsalis were investigated using light and Transmission Electron Microscopy (TEM). Each gland showed dense aggregates of secretory cells organized into visually distinct lobes; a long collecting canal that drains the secretion tow…
Centrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity in Pb-Pb Collisions at √sNN = 5.02 TeV
2016
The pseudorapidity density of charged particles, dNch=dη, at midrapidity in Pb-Pb collisions has been measured at a center-of-mass energy per nucleon pair of √sNN=5.02 TeV. For the 5% most central collisions, we measure a value of 1943±54. The rise in dNch=dη as a function of √sNN is steeper than that observed in proton-proton collisions and follows the trend established by measurements at lower energy. The increase of dNch=dη as a function of the average number of participant nucleons, hNparti, calculated in a Glauber model, is compared with the previous measurement at √sNN=2.76 TeV. A constant factor of about 1.2 describes the increase in dNch=dη from √sNN=2,76 to 5.02 TeV for all central…
Oblicza przemocy w dyskursie nauki, publicystyki oraz w doświadczeniach ofiar
2019
W artykule przedstawiam jeden rodzaj przemocy – przemoc w rodzinie i jej konsekwencje. Proponuję spojrzenie na ten problem z dwóch różnych, wzajemnie uzupełniających się perspektyw. Z perspektywy teorii nauk społecznych, oraz z perspektywy towarzyszącego im dyskursu publicznego. Opisuję także doświadczenia ofiar przemocy. Zastosowane metody analizy to krytyczna analiza tekstów naukowych, krytyczna analiza publicystyki, wywiad skoncentrowany na problemie oraz krytyczna analiza wypowiedzi dorosłych, którzy na podstawie retrospekcji udostępnili swoje doświadczenia związane z przemocą w rodzinie. Kontekstem zaprezentowanych analiz jest krytycznie zrekonstruowany dyskurs dotyczący przeobrażeń ws…

Longitudinal associations between teacher-child interactions and academic skills in elementary school
2017
This study examined the extent to which the quality of teacher-child interactions assessed in kindergarten (6-year-olds) is associated with children's reading and math development across the elementary school years. The sample consisted of 515 Finnish children (271 boys, 244 girls). Teacher-child interactions were observed in 49 kindergarten classrooms. The findings from the latent growth curve models showed that high-quality teacher–child interactions in kindergarten were positively associated with the initial levels of reading and math skills. Furthermore, the results indicated that high-quality teacher-child interactions in kindergarten were positively associated with children's academic…
