Neuronal receptive endings, such as dendritic spines and sensory protrusions, are structurally remodeled by experience. How receptive endings acquire their remodeled shapes is not well understood. In response to environmental stressors, the nematode Caenorhabditis elegans enters a diapause state, termed dauer, which is accompanied by remodeling of sensory neuron receptive endings. Here, we demo...

Soil properties, under the major influence of agricultural practices in cultivated fields, distribution and quality water vary greatly space time. In conservation agriculture (CA), combination implemented can modify retention circulation. this study, fields managed CA adjacent with regular ploughing (CONV) were used to characterize functioning soils Adour-Garonne basin south-western France. Hyd...

Abstract Introduction There is an association between surgeon volume and outcomes in hernia surgery, yet little evidence regarding impact of the experience performing abdominal wall closure (AWC) on IH rate. Our aim was to assess rates at 1 year following surgery Registrar Consultant surgeons patients undergoing elective colorectal surgery. Methods Patients for cancer 2014-2018 were identified ...

While most sensory neurons will adapt to prolonged stimulation by down-regulating their responsiveness to the signal, it is not clear which events initiate long-lasting sensory adaptation. Likewise, we are just beginning to understand how the physiology of the adapted cell is altered. Caenorhabditis elegans is inherently attracted to specific odors that are sensed by the paired AWC olfactory se...

In the present study, we used the African Wildcat (Felis silvestris lybica) as a somatic cell donor to evaluate the in vivo developmental competence, after transfer into domestic cat recipients, of cloned embryos produced by the fusion of African Wildcat (AWC) fibroblast cell nuclei with domestic cat cytoplasts. Cloned embryos were produced by fusion of a single AWC somatic cell to in vivo or i...

European beech (Fagus sylvatica L.) trees are becoming vulnerable to drought, with a warming climate. Existing studies disagree on how radial growth varies in response droughts. We aimed find the impact of multiple droughts trees’ annual at their ecological drought limit created by soil water availability forest. Besides, we quantified influence competition and canopy openness mean basal area t...

Prolonged stimulation leads to specific and stable changes in an animal's behavior. In interneurons, this plasticity requires spatial and temporal control of neuronal protein synthesis. Whether such translational control occurs in sensory neurons is not known. Adaptation of the AWC olfactory sensory neurons of C. elegans requires the cGMP-dependent protein kinase EGL-4. Here, we show that the R...

RasGRPs, which load GTP onto Ras and Rap1, are expressed in vertebrate and invertebrate neurons. The functions, regulation, and mechanisms of action of neuronal RasGRPs are unknown. Here, we show how C. elegans RGEF-1b, a prototypical neuronal RasGRP, regulates a critical behavior. Chemotaxis to volatile odorants was disrupted in RGEF-1b-deficient (rgef-1⁻/⁻) animals and wild-type animals expre...
