Impairments in expression of devaluation in a Pavlovian goal-tracking task, but not a free operant devaluation task, after fentanyl exposure in female rats.

In laboratory animals, there are numerous demonstrations that past exposure to drugs of abuse can lead to devaluation impairments weeks after the final drug exposure, with the majority of these demonstrations examining effects of exposure to psychostimulants. There has been minimal investigation into whether prior exposure to opiates can lead to devaluation impairments. Here, we first trained female rats that two separate cuelights predicted two different foods and measured Pavlovian goal-tracking responses (Experiment 1) or trained female rats to press two levers to earn two different foods and measured this operant response (Experiment 2).

[Learning about the caregiving relationship in the internship].

Nursing students are confronted with the mysteries of the patient encounter during their internship in psychiatry. From this discovery, questions and enigmas remain to be solved. This ephemeral primary relationship, in a time span of a few weeks, is a source of frustration for them.

[The meeting, a lever towards the exercise of nursing care in psychiatry].

Nursing training is provided in nursing training institutes by a multidisciplinary teaching team. During this course, the nursing student will forge his or her professional identity. However, psychiatry is a field that is not very popular with students.

[To experience one's physicality through the "bizarre" experience of touching oneself].

The touch of oneself is essential in the construction of a conscious self. It contributes to the feeling of ownership of the body. Feeling touched and touching reveals the subject in a being-self inscribed in its environment.

Response of Three × Cultivars to Toxic Elements Stress: Part 2, Comparison between Two Growing Seasons.

The positive impact on restoring soil functionality, decreasing toxic elements (TE) bioaccessibility, and enhancing soil physicochemical and biological parameters established a consensus on considering a × convenient species for phytomanaging wide TE contaminated areas. Nevertheless, information about the plant's mode of reaction to elevated soil multi-TE concentrations is still scarce. For the sake of investigating the miscanthus response to stressful TE concentrations, an ex-situ pot experiment was initiated for 18 months, with three miscanthus cultivars referred to as B, U, and A planted in soils with gradient Cd, Pb, and Zn concentrations.

Interactive effects of metals and carbon nanotubes in a microcosm agrosystem.

Agricultural soils are exposed to multiple contaminants through the use of agrochemicals or sewage sludge, introducing metals, nanomaterials and others. Among nanomaterials, carbon nanotubes (CNTs) are known for their large surface area and adsorption capabilities, possibly modifying other element behavior. However, to date, very little is known about the impacts of such interactions in agrosystems.

Response of Three Cultivars to Toxic Elements Stress: Part 1, Plant Defence Mechanisms.

demonstrated good phytostabilization potentials in toxic element (TE) contaminated soils. However, information about its tolerance to elevated concentrations is still scarce. Therefore, an ex-situ pot experiment was launched using three cultivars (termed B, U, and A) grown in soils with a gradient Cd, Pb and Zn concentrations.

Developing Drugs for Prevention of Chemotherapy-Induced Nausea and Vomiting: Draft Guidance from the FDA.

The administration of preventative therapy for chemotherapy-induced nausea and vomiting (CINV) is an essential component of the treatment plan for many patients with cancer. In May 2021, the FDA issued a draft guidance for industry to facilitate the clinical development of drugs for the prevention of CINV in adults. FDA guidance has a vital role in the regulatory dialogue between the Agency and external stakeholders.

Comparative study of response of four crop species exposed to carbon nanotube contamination in soil.

Crop plants are exposed to a variety of contaminants through sewage sludge spreading but very little is known about the impact of emerging contaminants such as nanomaterials. To date their impact on plants is still very controversial with many works claiming negative impacts while some authors suggest their use as plant growth regulator in agriculture. In this study, aiming to better understand where these discrepancies may come from, we investigated the influence of plant species (tomato, rapeseed, cucumber and maize) on plant response to a carbon nanotube contamination in soil condition.

[Not Available].

Introduction : The COVID-19 pandemic has warranted the implementation of barrier actions and the wearing of personal protective equipment (PPE). These behavioral adaptations counteract spontaneous self-touching reflex gestures. I propose to explore the mind-body experience generated by these gesture changes in this health context.

Miscanthus x giganteus culture on soils highly contaminated by metals: Modelling leaf decomposition impact on metal mobility and bioavailability in the soil-plant system.

Miscanthus x giganteus is suggested as a good candidate for phytostabilization of metal-polluted soils. Its late harvest in winter generates large amounts of leaf litter on the soil surface. However, little is known about the mobility and the bioavailability of metals following leaf decomposition and the consequences on the succeeding culture.

Genotypes of the aquatic plant Myriophyllum spicatum with different growth strategies show contrasting sensitivities to copper contamination.

Genotypic variability has been considered for years as a key attribute in species adaptation to new environments. It has been extensively studied in a context of chemical resistance, but remains poorly studied in response to chemical exposure in a context of global change. As aquatic ecosystems are particularly affected by environmental changes, we aimed to study how genotypic variability could inflect the sensitivity of aquatic plants to chemicals.

Leaf mineral content govern microbial community structure in the phyllosphere of spinach (Spinacia oleracea) and rocket (Diplotaxis tenuifolia).

The plant microbiome is an important factor for plant health and productivity. While the impact of nitrogen (N) availability for plant growth and development is well established, its influence on the microbial phyllosphere community structure is unknown. We hypothesize that nitrogen impacts the growth and abundance of several microorganisms on the leaf surface.

Assessing the impacts of sewage sludge amendment containing nano-TiO on tomato plants: A life cycle study.

Increasing evidence indicates the presence of engineered nanoparticles (ENPs) in sewage sludge derived from wastewater treatment. Land application of sewage sludge is, therefore, considered as an important pathway for ENP transfer to the environment. The aim of this work was to understand the effects of sewage sludge containing nano-TiO on plants (tomato) when used as an amendment in agricultural soil.

Transfer and Ecotoxicity of Titanium Dioxide Nanoparticles in Terrestrial and Aquatic Ecosystems: A Microcosm Study.

With the advancement in nanotechnology, particularly the use of TiO nanoparticles (NPs), there is a need to study their release into the environment and assess the related risk in an environmentally relevant contamination scenario. In the present study, the transfer and toxicity of TiO NPs in microcosms mimicking terrestrial and aquatic ecosystems were evaluated. The contaminated soil was prepared by spiking natural soils, with these then used as the basis for all exposure systems including preparation of soil leachates for amphibian exposure.

Can zinc pollution promote adaptive evolution in plants? Insights from a one-generation selection experiment.

Human activities generate environmental stresses that can lead plant populations to become extinct. Population survival would require the evolution of adaptive responses that increase tolerance to these stresses. Thus, in pseudometallophyte species that have colonized anthropogenic metalliferous habitats, the evolution of increased metal tolerance is expected in metallicolous populations.

[My stomach, the monster under my bed].

Care for patients with eating disorders is complex and plurimodal. Care plans need to be adapted in order to take into account the body in crisis. A series of hospital admissions combined with specific psychomotor approaches, can contribute to the patient being reappropriated with their own body.

A qualitative exploration of the work of embodiment in adolescent girls with obesity.

Social representations generally associate obesity, especially in adolescent girls, with sedentariness, lack of self-control and laziness. These girls thus have substantial problems of self-esteem. Dietary, lifestyle and behavioural approaches alone cannot address this issue, for they do not apprehend all of the complexity of obesity.

Prophylactic Sacral Dressing for Pressure Ulcer Prevention in High-Risk Patients.

Background: Patients in intensive care units are likely to have limited mobility owing to hemodynamic instability and activity orders for bed rest. Bed rest is indicated because of the severity of the disease process, which often involves intubation, sedation, paralysis, surgical procedures, poor nutrition, low flow states, and poor circulation. These patients are predisposed to the development and/or the progression of pressure ulcers not only because of their underlying diseases, but also because of limited mobility and deconditioned states of health.
