Objective To determine whether perceived age correlates with survival and important age related phenotypes. Design Follow-up study, with survival of twins determined up to January 2008, by which time 675 (37%) had died. Setting Population based twin cohort in Denmark. Participants 20 nurses, 10 young men, and 11 older women (assessors); 1826 twins aged ≥70. Main outcome measures Assessors: perc...

Polymers of intrinsic microporosity (PIMs) are a group of polymers with molecular sieve behaviour due to their rigid, contorted macromolecular backbones. They show great potential in organophilic pervaporation, solvent-resistant nanofiltration and gas and vapour separations. However, they are susceptible to physical ageing, leading to a reduction in permeability over time. An improvement in mem...

Ageing is a complex process and a broad spectrum of physical, psychological, and social changes over time. Accompanying diseases and disabilities, which can interfere with cancer treatment and recovery, occur in old ages. MicroRNAs (miRNAs) are a set of small non-coding RNAs, which have considerable roles in post-transcriptional regulation at gene expression level. In this review, we attempted ...

BACKGROUND The exact impact of ageing on skeletal muscle phenotype and mitochondrial and lipid content remains controversial, probably because physical activity, which greatly influences muscle physiology, is rarely accounted for. The present study was therefore designed to investigate the effects of ageing, physical activity, and pre-frailty on skeletal muscle phenotype, and mitochondrial and ...

INTRODUCTION Given the biological complexity of the ageing process, there is no single, simple and reliable measure of how healthily someone is ageing. Intervention studies need a panel of measures which capture key features of healthy ageing. To help guide our research in this area, we have adopted the concept of the "Healthy Ageing Phenotype" (HAP) and this study aimed to (i) identify the mos...

BACKGROUND The number of people of advanced age (85 years and older) is increasing and health systems may be challenged by increasing health-related needs. Recent overseas evidence suggests relatively high levels of wellbeing in this group, however little is known about people of advanced age, particularly the indigenous Māori, in Aotearoa, New Zealand. This paper outlines the methods of the st...

This paper proposes SiC MOSFET gate ageing-laws under repetitive short-circuit stress. Based on analytical studies, physical forms and preconditioning data, numerical fitting based stress variables ΔTj, TPulse Gate Damage % Esc is proposed. Accuracy prediction capabilities of have been evaluated compared. Resulting in suggesting a new ageing-law ΔTAl_Top metal-source. one gives the best accurac...

INTRODUCTION The 12-item Expectations Regarding Aging (ERA-12) instrument measures expectations that individuals have about how their health and cognitive function will be when they age. To date, primarily assessed among older adults in Western settings, expectations regarding ageing have been associated with physical activity and healthcare seeking behaviour. It has been suggested that it may ...

Objective: While life expectancy is improving for persons with spinal muscular atrophy, new physical complaints may arise. To investigate this, we studied persons with a long duration and severe course (high functional limitations) of the disease. Design: Cross-sectional descriptive study. Subjects/Patients: Persons with spinal muscular atrophy. Methods: Questionnaires and structured interviews...

Gelatinised wheat starch, freeze dried and equilibrated at different RH, was aged at different temperatures and for different times. The Tool-Narayanaswamy-Moynihan (TNM) model was used to describe the ageing for all samples under all conditions. Three TNM parameters: x, Δh* and A were determined experimentally using, respectively, the peak shift method (x) and the dependency of T'(f) (the limi...
