Optimisation des techniques de chimiothérapie intracavitaire
2013
Introduction. In order to achieve a good effect, chemotherapy drugs need to penetrate into the peritoneal (HIPEC) or pleural tissue. Hyperthermia and high-pressure may enhance this penetration. The aim of this study was to evaluate their peritoneal effect and to establish the best technique to it. A feasibility study of an intrapleural high-pressure was an essential step to export these effects to the thoracic space. Methods. Four groups of pigs underwent an open HIPEC with a constant concentration (150 mg/l) of oxaliplatin during 30 minutes either in normothermia, or in hyperthermia (42-43°C); and either with atmospheric pressure or with high-pressure (25 cmH2O). Two more groups underwent …
Genomic characterization of mosaic cutaneous pigmentary disorders
2019
Ntroduction: Mosaic cutaneous dyschromia is strongly evocative of an underlying genetic mosaicism. These post-zygotic events are challenging for conventional diagnostic tools. Thus, genetic basis of mosaic cutaneous dyschromia still remained poorly understood. Materials and Methods: The M.U.S.T.A.R.D. cohort gathers DNA from skin biopsies of patients with mosaic cutaneous dyschromia. After a specialised phenotype analysis, they are referred to either trio exome sequencing (ES) at 200X, or targeted ultra-deep sequencing (60,000X) of candidate genes. Data are analysed with a tailored pipeline, allowing detection of both low-rate nucleotidic variations or chromosomal events. Results: From 2013…
Ritual function of hypnosis in the follow-up of persistent grief disorders
2017
Hypnotic processes are the subject of transdisciplinary studies that attest to a specific state and involve relational and contextual dimensions (Rainville, 2004; Bioy, 2017). This research is carried out in the context of Persistent Grief Disorders (P.G.D.., Prigerson, 2009, Zech, 2006, Fasse, 2013). A pharmacological approach improves the depressive component without affecting the specific symptoms of PGD, questioning the place of psychotherapeutic interventions (Hensley, 2006). This exploratory research questions the meaning that hypnotic experience can take in a PGD context and describes a phenomenology. The ritual dimension of the hypnotic device could underlie the phenomena of "immedi…
'Immunogenetics of Aging': report on the activities of the 15th International HLA and Immunogenetics Working Group and 15th International HLA and Imm…
2011
'Immunogenetics of Aging' is a component that was first included in the 14th International HLA and Immunogenetics Workshop (IHIWS) and developed further within the 15th Workshop. The aim of this component was to assess the impact of human leukocyte antigen (HLA) genes, cytokine genes, and some innate immunity genes such as killer-cell immunoglobulin-like receptors (KIRs) and mannose-binding lectin 2 (MBL2) in successful aging and their contribution to the better understanding of immune dysfunction in old age. Within the 15th IHIWS new populations were included in the analysis. Additional cytokine gene polymorphisms were assessed and innate immunity genes were analyzed for possible relevance…
Ambient Air Pollution Increases the Risk of Cerebrovascular and Neuropsychiatric Disorders through Induction of Inflammation and Oxidative Stress
2020
Exposure to ambient air pollution is a well-established determinant of health and disease. The Lancet Commission on pollution and health concludes that air pollution is the leading environmental cause of global disease and premature death. Indeed, there is a growing body of evidence that links air pollution not only to adverse cardiorespiratory effects but also to increased risk of cerebrovascular and neuropsychiatric disorders. Despite being a relatively new area of investigation, overall, there is mounting recent evidence showing that exposure to multiple air pollutants, in particular to fine particles, may affect the central nervous system (CNS) and brain health, thereby contributing to …
Reacciones de CO2 con nucleófilos carbonado y nitrogenados: aplicaciones en síntesis
2015
Las reacciones de carboxilación de nucleófilos carbonados y nitrogenados, así como de descarboxilación de los productos presentan una notable complejidad mecanística que sigue siendo objeto de discusión actualmente. El objetivo general del presente estudio plantea la exploración de estas reacciones y su eventual aplicación en síntesis. En el primer capítulo se describen las reacciones de carboxilación de aniones enolato y la química de los β-cetocarboxilatos alcalinos correspondientes en el contexto de su aplicación en reacciones de alquilación monoselectiva. Los resultados muestran el impacto de la agregación y los equilibrios ácido-base sobre la evolución de los intermedios de reacción, y…
The influence of yeast glycosylated proteins on tannins aggregation in model solution
2004
<p style="text-align: justify;">The incidence of glycosylated yeast proteins on tannins aggregation in model solution was investigated using the spectrophotometric method (absorbance 700 nm). Glycosylated proteins released by two commercial <em>Saccharomyces cerevisiae</em> strains (RC212 and BM 45) during alcoholic fermentation in synthetic media, glycosylated proteins extracted by Peat’s method and industrial glycosylated proteins purified and separated by chromatography on Sepharose Concanavalin A were used to visualize effects on tannins aggregation. Results showed that tannins aggregation was limited by the glycosylated proteins according to their origin and their mod…

Me, Myself, and My Thoughts: The Influence of Brooding and Reflective Rumination on Depressive Symptoms in Athletes in the United Kingdom
2020
Individual differences in vulnerability to depression are still underexplored in athletes. We tested the influence of different brooding and reflective rumination profiles (i.e., repetitive thought processes in response to low/depressed mood) on the odds of experiencing clinically relevant depressive symptoms in competitive athletes (N = 286). The Patient Health Questionnaire–9 and the Ruminative Responses Scale–short form were utilized to measure depression and rumination, respectively. Compared to athletes with a low brooding/reflection profile, athletes with a high brooding/reflection profile had significantly higher odds of experiencing clinical levels of depressive symptoms (OR = 13.40…
Boat traffic in Lampedusa waters (Strait of Sicily, Mediterranean Sea) and its relation to the coastal distribution of common bottlenose dolphin (Tur…
2010
The volume of boat traffic and its potential connection to the coastal distribution of the common bottlenose dolphin (Tursiops truncatus) was evaluated off Lampedusa Island (Strait of Sicily). From July to September 2006 daily surveys were carried out at eight sites along the coast, three times a day, to assess the number, type, and size of boats moving, fishing, or stationed in Lampedusa waters. The study area was divided into four geographic areas: northwest, northeast, southwest, and southeast. Data were analyzed to determine the difference in the number of boats among the areas, sampling months, and times of day. The presence of dolphins was monitored by standardized land-based observat…
