Positive affectivity and health
2011
RESUMEN Clásicamente se ha relacionado la afectividad positiva con la salud, y se intuye que hay una conexión directa entre ambas. De hecho, se cree que el desarrollo de sentimientos y emociones positivas ejerce un papel preventivo respecto a la enfermedad; o lo que es lo mismo, actúa como factor protector de la salud. En este texto se pretende explorar la relación entre ambos conceptos a través de diversos postulados teóricos de la Psicología de las emociones. Como resultados principales destaca la confirmación de la hipótesis que apunta a una íntima relación entre estos dos aspectos. Muchos autores consideran que en la actitud o forma de reaccionar ante los estímulos que nos rodean, está …

Long-term effect of arsenic exposure: Results from an occupational cohort study
2018
Background In 1976 in Manfredonia (Italy), arsenic was released into the atmosphere due to an accident in a petrochemical plant. We aimed to analyze the mortality of workers involved in the factory for the site cleaning activities. Methods The cohort consisted of 1467 workers grouped into contract, fertilizer, and plastic workers. The outcome of interest was mortality for specific causes. Standardized mortality ratios (SMR) and 95% confidence intervals (95%CI) were computed. Results For all workers and all causes of death combined, the SMR was less than 1.0. Mortality ratios were increased for malignant neoplasms of the pleura, bone and melanoma of the skin. Contract workers, the group most…
Ontologia dell’accidente. Saggio sulla plasticità distruttrice
2019
In conseguenza di gravi traumi, talvolta per un nonnulla, la storia di ognuno di noi può subire un radicale cambiamento: la vita che avevamo progettato per anni è costretta a una deviazione improvvisa e irreversibile. Dal trauma sorge una personalità nuova, senza precedenti. Una personalità nata da un incidente, nata per accidente. Il fortuito diviene così sostanziale e l’inaspettato s’inscrive nel nucleo più profondo del nostro essere. Affrontando con delicatezza il tema dell’impatto che i traumi psicofisici possono avere sulla nostra vita, Catherine Malabou intraprende un’avventura filosofica e letteraria in cui Spinoza, Deleuze e Freud incrociano Ovidio, Kafka, Proust e Duras, disegnando…

Exposure to environmental radionuclides associates with tissue-specific impacts on telomerase expression and telomere length
2019
International audience; Telomeres, the protective structures at the ends of chromosomes, can be shortened when individuals are exposed to stress. In some species, the enzyme telomerase is expressed in adult somatic tissues, and potentially protects or lengthens telomeres. Telomeres can be damaged by ionizing radiation and oxidative stress, although the effect of chronic exposure to elevated levels of radiation on telomere maintenance is unknown for natural populations. We quantified telomerase expression and telomere length (TL) in different tissues of the bank vole Myodes glareolus, collected from the Chernobyl Exclusion Zone, an environment heterogeneously contaminated with radionuclides,…
Fitness costs of increased cataract frequency and cumulative radiation dose in natural mammalian populations from Chernobyl
2015
AbstractA cataract is a clouding of the lens that reduces light transmission to the retina and it decreases the visual acuity of the bearer. The prevalence of cataracts in natural populations of mammals and their potential ecological significance, is poorly known. Cataracts have been reported to arise from high levels of oxidative stress and a major cause of oxidative stress is ionizing radiation. We investigated whether elevated frequencies of cataracts are found in eyes of bank voles Myodes glareolus collected from natural populations in areas with varying levels of background radiation in Chernobyl. We found high frequencies of cataracts in voles collected from different areas in Chernob…
Fibroblasts from bank voles inhabiting Chernobyl have increased resistance against oxidative and DNA stresses
2018
Background Elevated levels of environmental ionizing radiation can be a selective pressure for wildlife by producing reactive oxygen species and DNA damage. However, the underlying molecular mechanisms that are affected are not known. Results We isolated skin fibroblasts from bank voles (Myodes glareolus) inhabiting the Chernobyl nuclear power plant accident site where background radiation levels are about 100 times greater than in uncontaminated areas. After a 10 Gy dose of gamma radiation fibroblasts from Chernobyl animals recovered faster than fibroblasts isolated from bank voles living in uncontaminated control area. The Chernobyl fibroblasts were able to sustain significantly higher do…
Frequency of dicentrics and contamination levels in Ukrainian children and adolescents from areas near Chernobyl 20 years after the nuclear plant acc…
2013
International audience; Purpose To survey the possible presence of chromosomal damage and internal contamination in a group of Ukrainian children and adolescents, 20 years after the Chernobyl accident at the Nuclear Power Plant. Materials and methods Cytogenetical procedures were performed according to dicentric assay in 55 Ukrainian children and adolescents (29 boys and 26 girls), living near Chernobyl. In addition, a whole body detector and urinalysis were used to detect internal contamination. Results 36 dicentrics were found in a total of 53,477 metaphases scored in these children, which reflected a frequency of dicentrics below the background level. On the other hand, internal contamin…
Association between food insecurity and fall-related injury among adults aged ≥65 years in low- and middle-income countries: The role of mental healt…
2021
Purpose:\ud \ud We investigated the association between food insecurity and fall-related injury among older adults from six low- and middle-income countries (LMICs), and the extent to which this association is mediated by mental health.\ud \ud Methods:\ud \ud Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. Past 12-month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Fall-related injury referred to those that occurred in the past 12 months. Multivariable logistic regression analysis and mediation analysis were conducted to assess association…
