Peaks of in situ N2O emissions are influenced by N2O producing and reducing microbial communities across arable soils
2018
International audience; Introduction Agriculture is the main source of terrestrial N2O emissions, a potent greenhouse gas and the main cause of ozone depletion ((Hu et al., 2015). The reduction of N2O into N2 by microorganisms carrying the nitrous oxide reductase gene (nosZ) is the only known biological process eliminating this greenhouse gas. Recent studies showed that a previously unknown clade of N2O-reducers (nosZII) was related to the potential capacity of the soil to act as a N2O sink (see Hallin et al., 2017 and references therein). However little is known about how this group responds to different agricultural practices. Here, we investigated how N2O-producers and N2O-reducers were …
Changes in Serine Racemase-Dependent Modulation of NMDA Receptor: Impact on Physiological and Pathological Brain Aging
2018
International audience; The N-methyl-D-Aspartate glutamate receptors (NMDARs) are pivotal for the functional and morphological plasticity that are required in neuronal networks for efficient brain activities and notably for cognitive-related abilities. Because NMDARs are heterogeneous in subunit composition and associated with multiple functional regulatory sites, their efficacy is under the tonic influence of numerous allosteric modulations, whose dysfunction generally represents the first step generating pathological states. Among the enzymatic candidates, serine racemase (SR) has recently gathered an increasing interest considering that it tightly regulates the production of D-serine, an…
Junctional adhesion molecules JAM-B and JAM-C promote autoimmune-mediated liver fibrosis in mice
2018
Fibrosis remains a serious health concern in patients with chronic liver disease. We recently reported that chemically induced chronic murine liver injury triggers increased expression of junctional adhesion molecules (JAMs) JAM-B and JAM-C by endothelial cells and de novo synthesis of JAM-C by hepatic stellate cells (HSCs). Here, we demonstrate that biopsies of patients suffering from primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) or autoimmune hepatitis (AIH) display elevated levels of JAM-C on portal fibroblasts (PFs), HSCs, endothelial cells and cholangiocytes, whereas smooth muscle cells expressed JAM-C constitutively. Therefore, localization and function of JA…
Culinary choices: A sociopsychological perspective based on the concept of distance to the object
2015
Culinary choices are a dynamic process that involves many considerations, including individual, contextual, cultural, and social factors. This study provides a better understanding of how culinary socialization along with food neophobia, culinary decisions and culinary habits, underlie culinary choices, measured by the concept of Distance to the Object (DO). This concept is useful in exploring the role of some psychosocial factors: knowledge (real and perceived), involvement (importance, personal identification, perceived ability), and level of practices (behaviors) associated with the social object under study, here, cooking. In this study, the DO concept measures the relationships of an i…
About human taeniasis and Taenia saginata diagnosis by endoscopy
2016
La carta al editor se refiere al articulo de Canaval-Zuleta et al. aceptado para publicacion, titulado "Endoscopy as an alternative diagnostic and therapeutic technique for Taenia saginata". El trabajo presenta una serie de incorrecciones que deben ser aclaradas, o al menos parte de ellas en solo 300 palabras. La informacion sobre las vias de infeccion en taeniasis, asi como la patogenia y tecnicas de diagnostico, no se ajustan a la realidad. Asimismo, ya esta publicado que el diagnostico por endoscopia es una tecnica muy sensible pero nada especifica, pues no permite distinguir entre las 3 especies humanas del genero Taenia.
The role of extracellular calcium in bone metastasis
2016
AbstractThis review summarizes the role of extracellular calcium, as found present in the bone tissue, in the process of bone metastasis.
Music style not only modulates the auditory cortex, but also motor related areas
2021
The neuroscience of music has recently attracted significant attention, but the effect of music style on the activation of auditory-motor regions has not been explored. The aim of the present study is to analyze the differences in brain activity during passive listening to non-vocal excerpts of four different music genres (classical, reggaeton, electronic and folk). A functional magnetic resonance imaging (fMRI) experiment was performed. Twenty-eight participants with no musical training were included in the study. They had to passively listen to music excerpts of the above genres during fMRI acquisition. Imaging analysis was performed at the whole-brain-level and in auditory-motor regions …

Mitochondrial DNA Haplogroup JT is Related to Impaired Glycaemic Control and Renal Function in Type 2 Diabetic Patients
2018
The association between mitochondrial DNA (mtDNA) haplogroup and risk of type 2 diabetes (T2D) is undetermined and controversial. This study aims to evaluate the impact of the main mtDNA haplogroups on glycaemic control and renal function in a Spanish population of 303 T2D patients and 153 healthy controls. Anthropometrical and metabolic parameters were assessed and mtDNA haplogroup was determined in each individual. Distribution of the different haplogroups was similar in diabetic and healthy populations and, as expected, T2D patients showed poorer glycaemic control and renal function than controls. T2D patients belonging to the JT haplogroup (polymorphism m.4216T>
