Emotional expressiveness of 5–6 month-old infants born very premature versus full-term at initial exposure to weaning foods
2016
International audience; Facial expressions of 5-6 month-old infants born preterm and at term were compared while tasting for the first time solid foods (two fruit and two vegetable purees) given by the mother. Videotapes of facial reactions to these foods were objectively coded during the first six successive spoons of each test food using Baby FACS and subjectively rated by naive judges. Infant temperament was also assessed by the parents using the Infant Behaviour Questionnaire. Contrary to our expectations, infants born preterm expressed fewer negative emotions than infants born full-term. Naive judges rated infants born preterm as displaying more liking than their full-term counterparts…
Mutual Antagonism between Circadian Protein Period 2 and Hepatitis C Virus Replication in Hepatocytes
2013
BackgroundHepatitis C virus (HCV) infects approximately 3% of the world population and is the leading cause of liver disease, impacting hepatocyte metabolism, depending on virus genotype. Hepatic metabolic functions show rhythmic fluctuations with 24-h periodicity (circadian), driven by molecular clockworks ticking through translational-transcriptional feedback loops, operated by a set of genes, called clock genes, encoding circadian proteins. Disruption of biologic clocks is implicated in a variety of disorders including fatty liver disease, obesity and diabetes. The relation between HCV replication and the circadian clock is unknown.MethodsWe investigated the relationship between HCV core…
''Effect of stroke on arginase expression and localization in the rat brain''
2013
Quirie, Aurore | Demougeot, C. Eline | Bertrand, Nathalie | Mossiat, Claude | Garnier, Philippe | Marie, Christine | Prigent-Tessier, Anne; International audience; ''Because arginase and nitric oxide (NO) synthases (NOS) compete to degrade l-arginine, arginase plays a crucial role in the modulation of NO production. Moreover, the arginase 1 isoform is a marker of M2 phenotype macrophages that play a key role in tissue remodeling and resolution of inflammation. While NO has been extensively investigated in ischemic stroke, the effect of stroke on the arginase pathway is unknown. The present study focuses on arginase expression/activity and localization before and after (1, 8, 15 and 30days) …
Targets and dimensions of social comparison among people with spinal cord injury and other health problems
2006
The present research examined comparison targets and comparison dimensions among two Spanish samples of individuals facing serious illnesses and diseases. In Study 1, 90 older patients (mean age 66.36) with various age-related diseases, particularly cardiovascular diseases and diabetes, indicated that they compared themselves most often with others with the same disease, next with others with another disease and least with people without health problems. They compared themselves more often on their mental state, symptoms and physical activities than on their social activities. Social comparison orientation (SCO) as an individual difference characteristic was associated with more frequent co…
Sex differences in the psychophysiological response to an intergroup conflict.
2018
Abstract Conflict induces psychophysiological responses, but less is known about responses to intergroup conflict. Intergroup relationships activate social processes, adding complexity to people’s physiological responses. This study analyzes the psychophysiological responses to intergroup conflict considering sex differences. Thus, 150 young people were distributed in 50 groups in two conditions (conflict vs. non-conflict). Conflict was created in the interaction between two groups (three people each) in the laboratory. Their responses were compared to a control group. Mood, heart rate variability, cortisol, and testosterone were measured. Results showed that intergroup conflict induced a l…
Effects of an eccentric training personalized by a low rate of perceived exertion on the maximal capacities in chronic heart failure: a randomized co…
2016
International audience; BACKGROUND: The eccentric (ECC) training, in spite of its potential interest (slightest request of the cardiorespiratory system) compared with the concentric (CON) training, is not applied during the rehabilitation of the chronic heart failure (CHF). The main reasons are the difficulty personalizing the ECC exercises by avoiding the muscle complications and the lack of information concerning the specific effects on the maximal capacities in CHF patients.AIM: To compare — following a prior study on the feasibility and on the functional impacts — the effects on maximal capacities and tolerance in CHF of ECC training tailored by a low rate of perceived exertion (RPE) an…
Abnormal functioning of the left temporal lobe in language-impaired children
2014
Specific language impairment is associated with enduring problems in language-related functions. We followed the spatiotemporal course of cortical activation in SLI using magnetoencephalography. In the experiment, children with normal and impaired language development heard spoken real words and pseudowords presented only once or two times in a row. In typically developing children, the activation in the bilateral superior temporal cortices was attenuated to the second presentation of the same word. In SLI children, this repetition effect was nearly nonexistent in the left hemisphere. Furthermore, the activation was equally strong to words and pseudowords in SLI children whereas in the typi…
Aquatic cycling-What do we know? A scoping review on head-out aquatic cycling
2017
Over the past few years, aquatic cycling has become a trending fitness activity. However, the literature has not been reviewed exhaustively. Therefore, using scoping review methodology, the aim of this review was to explore the current state of the literature concerning aquatic cycling. This study specifically focused on study designs, populations and outcomes. A comprehensive search of seven databases (PubMed, MEDLINE, Cinahl, Embase, PEDro, Web of Science, WorldCat) was conducted up to 30th September 2016. GoogleScholar, World Cat, ResearchGate, specific aquatic therapy websites and aquatic therapy journals were searched to identify additional literature. Full-text publications in English…
Bout duration and number of players of soccer small-sided games affect perceived enjoyment, physiological responses, and technical-tactical performan…
2021
To compare perceived enjoyment (PE), % of heart rate peak (%HRpeak), blood lactate (La), rating of perceived exertion (RPE), and technical-tactical performance of soccer players after four-a-side (4vs4) and three-a-side (3vs3) small-sided games (SSGs) with goalkeepers.Sixteen males (20.7 ± 0.7 years; experience: 6.9 ± 1.2 years) completed and were measured after six sessions of SSGs (one twelve-minute bout (1x12), two six-minute bouts (2x6), and three four-minute bouts (3x4), both 3vs3 and 4vs4). Repeated measurements ANOVA evaluated significant differences (There was higher PE for 1 × 12 compared to 2 × 6 (effect sizes [ES] = 1.53 [3vs3 and 4vs4]) and 3 × 4 (ES = 3.13 [4vs4] and 4.16 [3vs3…
Being moved by listening to unfamiliar sad music induces reward‐related hormonal changes in empathic listeners
2021
Many people enjoy sad music, and the appeal for tragedy is widespread among the consumers of film and literature. The underlying mechanisms of such aesthetic experiences are not well understood. We tested whether pleasure induced by sad, unfamiliar instrumental music is explained with a homeostatic or a reward theory, each of which is associated with opposite patterns of changes in the key hormones. Sixty-two women listened to sad music (or nothing) while serum was collected for subsequent measurement of prolactin (PRL) and oxytocin (OT) and stress marker (cortisol and adrenocorticotropic hormone) concentrations. Two groups of participants were recruited on the basis of low and high trait e…
