Olfactory cues and the value of information : Voles interpret cues differently based on recent predator encounters

2018

Prey strategically respond to the risk of predation by varying their behavior while balancing the tradeoffs of food and safety. We present here an experiment that tests the way the same indirect cues of predation risk are interpreted by bank voles, Myodes glareolus, as the game changes through exposure to a caged weasel. Using optimal patch use, we asked wild-caught voles to rank the risk they perceived. We measured their response to olfactory cues in the form of weasel bedding, a sham control in the form of rabbit bedding, and an odor-free control. We repeated the interviews in a chronological order to test the change in response, i.e., the changes in the value of the information. We found…

Safety and potential interaction of immunosuppressive drugs for the treatment of inflammatory bowel disease in elderly patients

2021

Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, are chronic diseases associated with increased morbidity and reduced quality of life. Age may represent a risk factor for adverse events, due to the multimorbidity and polypharmacy, common in elderly patients. Elderly are often not included in clinical trials evaluating efficacy and safety of study drugs for the treatment of inflammatory bowel diseases. Several drugs, such as aminosalicylates, systemic corticosteroids, immunosuppressant drugs, biological drugs and Janus Kinase inhibitors, are available for the management of inflammatory bowel diseases. With the increasing spectrum of therapeutic options, it is th…

Tenapanor for the treatment of irritable bowel syndrome with constipation.

2020

Introduction: Irritable bowel syndrome with constipation is associated with higher rates of functional impairment, as compared to other subtypes of the syndrome. Conventional laxative-based pharmacologic therapy of IBS-C, which is mostly symptom-based, is often unsatisfactory. Tenapanor represents a first-in-class orally available inhibitor of NHE3, which is minimally absorbed in the GI tract, what constitutes a significant therapeutic benefit, as it may act on the drug target. Areas covered: Aim of this article is to sum up the evidences about pharmacodynamics and pharmacokinetics of tenapanor, focusing on animal models and in vitro studies, but also discuss clinical trials on tenapanor's …

Les déterminants personnels du bien-être de l’écolier, de ses satisfactions en classe et de sa performance scolaire

2017

This work focuses on the study of personal determinants of pupils' achievement and reactions toward class (well-being; satisfaction with teacher, learning and class). A theoretical model is tested by commonality analysis and refined by causal paths analysis. The results show that external and cognitive prior characteristics (age, gender, socio-occupational background, academic record) have direct effects on criteria variables, and indirectly via the attitudes toward school (negative feelings; scholastic interest; aspirations for future studies; "scholastic anxiety, worry and stress"; fun school). Using two structural models, we explained 39 % of the variance in academic achievement, and fro…

Towards a framework for assessment and management of cumulative human impacts on marine food webs

2015

Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…

Testing refined shell-model interactions in the sd shell: Coulomb excitation of 26Na

2015

Background: Shell-model calculations crucially depend on the residual interaction used to approximate the nucleon-nucleon interaction. Recent improvements to the empirical universal sd interaction (USD) describing nuclei within the sd shell yielded two new interactions—USDA and USDB—causing changes in the theoretical description of these nuclei. Purpose: Transitionmatrix elements between excited states provide an excellent probe to examine the underlying shell structure. These observables provide a stringent test for the newly derived interactions. The nucleus 26Na with 7 valence neutrons and 3 valence protons outside the doubly-magic 16O core is used as a test case. Method: A radioactive b…

Dual action of phosphonate herbicides in plants affected by herbivore—Model study on black bean aphid Aphis fabae rearing on broad bean Vicia faba pl…

2008

Abstract The interactions between plants, herbicides and herbivore insects were studied as an aspect of possible side effect of the using of phosphonate herbicides. The experimental system was composed of phosphonate herbicides, broad bean Vicia faba (L.) plants and black bean aphid Aphis fabae (Scopoli). Two means of herbicide application, namely standard spraying and direct introduction of the herbicide into stem via glass capillary, were examined. The results obtained for N-2-piridylaminomethylene bisphosphonic acid and its derivatives show 10 times higher inhibition of the plant growth if glass capillary mode was used. When plants were infested by aphids 24 h after the use of herbicide,…

Research data supporting "Social learning within and across predator species reduces attacks on novel aposematic prey"

2019

This data is from the experiment that investigated how wild-caught blue tits and great tits use conspecific and heterospecific information about unpalatable prey, published at the Journal of Animal Ecology (2020). The experiment was conducted at the Konnevesi Research Station from October to December 2017. Sheet 1 (“Main experiment”) contains data from the main avoidance learning experiment. Sheets 2 (“Symbol preference blue tits”) and 3 ("Symbol visibility blue tits") contain data of blue tits' symbol choices in initial preference and visibility tests.

Shell-model computed cross sections for charged-current scattering of astrophysical neutrinos off 40Ar

2018

Charged-current (anti)neutrino-$^{40}\mathrm{Ar}$ cross sections for astrophysical neutrinos have been calculated. The initial and final nuclear states were calculated using the nuclear shell model. The folded solar-neutrino scattering cross section was found to be $1.78(23)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}42}\phantom{\rule{4pt}{0ex}}{\mathrm{cm}}^{2}$, which is higher than what the previous papers have reported. The contributions from the ${1}^{\ensuremath{-}}$ and ${2}^{\ensuremath{-}}$ multipoles were found to be significant at supernova-neutrino energies, confirming the random-phase approximation (RPA) result of a previous study. The effects of neutrino flavor conve…
