A combined electrophysiological and morphological examination of episodic memory decline in amnestic mild cognitive impairment.

2013

Early stages of Alzheimer’s disease (AD) are characterized by neuropathological changes within the medial temporal lobe cortex (MTLC), which lead to characteristic impairments in episodic memory, i.e., amnestic mild cognitive impairment (aMCI). Here, we tested the neural correlates of this memory impairment using event-related potentials (ERPs) and voxel-based morphometry. Twenty-four participants were instructed to encode lists of words and were tested in a yes/no recognition memory task. The dual-process model of recognition memory dissociates between acontextual familiarity and recollection of contextual details. The early frontal ERP old/new-effect, which is thought to represent a neura…

Can the effects of gender, menopause and ageing on lipid levels be differentiated?

2016

The menopause, as well as ageing in both genders, can influence cardiovascular disease (CVD) risk1. An atherogenic lipoprotein profile, including small dense low density lipoprotein (sdLDL) particles, can be present even in normolipidaemic healthy young individuals (about 6%)2. If confirmed by larger studies, it will be necessary to consider different risk stratifications for those with atherogenic normolipidaemia and those with non-atherogenic hypercholesterolaemia. Furthermore, other changes associated with the menopause (increase in lipoprotein (a) [Lp(a)] levels, central obesity, endothelial dysfunction and systemic inflammation) may contribute to pro-atherogenic changes, while ethnicit…

Body Fat and Mobility Are Explained by Common Genetic and Environmental Influences in Older Women

2008

In older adults, mobility limitations often coexist with overweight or obesity, suggesting that similar factors may underlie both traits. This study examined the extent to which genetic and environmental influences explain the association between adiposity and mobility in older women. Body fat percentage (bioimpedance test), walking speed over 10 m, and distance walked in a 6-min test were evaluated in 92 monozygotic (MZ) and 104 dizygotic (DZ) pairs of twin sisters reared together, aged 63-76 years. Genetic and environmental influences on each trait were estimated using age-adjusted multivariate genetic modeling. The analyses showed that the means (and s.d.) for body fat percentage, walkin…

Physical activity is associated with better global cognition and frontal function in overweight/obese older adults with metabolic syndrome

2019

Background There is epidemiological evidence of an association between the metabolic syndrome (MetS), a cluster of cardiovascular risk factors related to central adiposity and insulin resistance, and cognitive impairment and dementia. On the other hand, there is evidence for a beneficial effect of physical activity on cognitive outcomes in older adult populations. In a cross-sectional study, we evaluated the relationship between aerobic physical activity and cognition in a cohort of overweight/obese older adults with MetS at risk for dementia. Cognitive function was assessed in a subsample of 82 subjects (men 55–75 y; women 60–75 y), with MetS and a BMI ≥27 to < 40 kg/m2 enrolled in the PRE…

Manejo de la hiperglucemia con fármacos no insulínicos en pacientes adultos con diabetes tipo 2

2019

Resumen: El adecuado tratamiento de la diabetes mellitus tipo 2 (DM2) incluye la alimentación saludable y el ejercicio (150 min/semana) como pilares básicos. Para el tratamiento farmacológico, la metformina es el fármaco de elección inicial, salvo contraindicación o intolerancia; en caso de mal control, se dispone de 8 familias terapéuticas (6 orales y 2 inyectables) como posibles combinaciones. Se presenta un algoritmo y unas recomendaciones para el tratamiento de la DM2. En prevención secundaria cardiovascular se recomienda asociar un inhibidor del cotransportador sodio-glucosa tipo 2 (iSGLT2) o un agonista del receptor de glucagon-like peptide-1 (arGLP1) en pacientes con obesidad. En pre…

Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests

2019

Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness i…

Arbuscular mycorrhizal fungi positively affect growth of Ailanthus altissima (Mill.) Swingle seedlings and show a strong association with this invasi…

2015

Arbuscular mycorrhizal fungi (AMF) may promote plant invasion by enhancing plant performance and competitiveness. However, only a small number of studies have considered the interactions between local soil microbial communities and invasive plants, and even fewer have focused on alien trees. Ailanthus altissima is a serious problem in the Mediterranean Basin, where it has invaded many habitats. We investigated the symbiosis between A. altissima and indigenous AMF in two invaded, ecologically different Mediterranean woodlands. Mycorrhizal infection was high at both sites (> 60% of the root fragments were mycorrhizal), indicating that A. altissima roots may be infected by AMF under different …

Les dynamiques du périurbain dijonnais entre 1990 et 1999

2009

Un étalement urbain accompagne désormais la croissance des villes, notamment les plus grandes. Principalement expliqué par un desserrement résidentiel, il est aussi la résultante des dynamiques de centralisation de l’emploi et de spécialisation des zones d’activité à l’intérieur des aires urbaines. L’exemple dijonnais met bien en lumière ce double mouvement qui affecte les communes de sa périphérie et contribue à accroître les mobilités. Urban sprawl arises from the growth of cities, especially of the biggest cities. This urban sprawl is accounted for mainly by residential clearing. It results also from the dynamics of centralization of employment and from specialization of activity zones i…
