Dysregulation of C-X-C motif ligand 10 during aging and association with cognitive performance

2017

International audience; Chronic low-grade inflammation during aging (inflammaging) is associated with cognitive decline and neurodegeneration; however, the mechanisms underlying inflammaging are unclear. We studied a population (n = 361) of healthy young and old adults from the MyoAge cohort. Peripheral levels of C-X-C motif chemokine ligand 10 (CXCL10) was found to be higher in older adults, compared with young, and negatively associated with working memory performance. This coincided with an age-related reduction in blood DNA methylation at specific CpGs within the CXCL10 gene promoter. In vitro analysis supported the role of DNA methylation in regulating CXCL10 transcription. A polymorph…

Factors influencing serum 25-hydroxivitamin D levels and other bone metabolism parameters in healthy older women

2016

Objective: Older women have frequently low serum 25-hydroxivitamin D (25[OH]D) concentrations, high parathormone (PTH) levels and low bone mineral density (BMD) values. Endogenous synthesis, dietary habits, sunlight exposure and fat-mass-mediated storage may influence 25(OH)D levels and bone metabolism, but the relevance of these factors in the elderly has yet to be fully elucidated. We aimed to investigate the influence of dietary vitamin D intake and fat mass on serum 25(OH)D levels and bone metabolism in older women. Design: Cross-sectional. Setting: Community. Participants: 218 fit older women attending a biweekly mild fitness program. Measurements: Dietary habits was investigated throu…

Olaratumab: PDGFR-α inhibition as a novel tool in the treatment of advanced soft tissue sarcomas

2017

Advanced soft tissue sarcomas are aggressive cancers with limited therapeutic options. Recently, inhibition of platelet-derived growth factor receptor (PDGFR)-α by the monoclonal antibody olaratumab showed promising clinical activity. If confirmed, this would be one of the first examples of targeted therapy effective in advanced soft tissue sarcomas therapy independently of the histologic subtype. Here, we reviewed the biology of the PDGF/PDGFR axis, particularly focusing on its role in cancer, and then we discussed on the effects of PDGFR-α inhibition in the therapy of advanced soft tissue sarcomas.

INFORMACIÓN Y EXPOSICIÓN INDIRECTA PARA REDUCIR ESTEREOTIPOS HACIA EL ENVEJECIMIENTO

2016

Abstract.Purpose: The Image that society has about older people has been built on a base of stereotypes, far away from reality. This social image will have a determinant influence on attitudes and behaviors from all those people related with them, including health care professionals. It should be mandatory to eradicate negative stereotypes against aging during university formation, and in this practice get sensitive professionals who will attend people in their final state of life. Method: the treatment “Information plus indirect experience” was set throw the viewing of the short film “Como un Rolling” (Castilla, 2013). This film exposes the concept of active aging, and had the purpose to b…

Identité narrative, déprise et vécu du vieillissement

2018

Cet article se propose d’envisager le rapport entre deprise et recit de soi comme source de continuite identitaire dans une perspective philosophique, en reference a la notion d’identite narrative de Paul Ricœur. Si le recit de soi permet de mettre en forme le temps que l’on vit sans supposer un noyau non changeant de l’identite, ce recit devrait favoriser le processus de deprise. Mais cette mise en forme du temps par le recit se heurte a plusieurs obstacles : l’invisibilite de notre propre vieillissement qui ne nous laisse pas l’elaborer, sauf a souscrire aux regards exterieurs qui nous objectivent ; la difficulte d’articuler ce recit avec nos valeurs fondamentales dans la duree du temps d…

Âge, perception chimiosensorielle et préférences alimentaires

2010

 Revue non indexée dans le JCR.; National audience; Le vieillissement s’accompagne d’un déclin des sensibilités olfactives et gustatives (sensibilités chimiosensorielles). Or, lorsque nous mangeons, la saveur et l’odeur d’un aliment contribuent largement au plaisir associé à son ingestion. Plusieurs auteurs ont fait l’hypothèse que le déclin des capacités chimiosensorielles observé chez les seniors conduirait à des modifications des préférences alimentaires, celles-ci entraînant à leur tour des changements de l’appétit et de la prise alimentaire. Effectivement, lorsque les préférences sont mesurées à un instant t, les seniors tendent à préférer des aliments ayant une flaveur plus intense. C…
