The Dietary Approaches to Stop Hypertension Diet, Cognitive Function, and Cognitive Decline in American Older Women

JAMDA | 01-06-2017 |   Abstract Objectives: To examine the association between long-term adherence to the Dietary Approaches to Stop Hypertension (DASH) diet with cognitive function and decline in older American women. Design: Prospective cohort study. Setting: The Nurses’ Health Study, a cohort of registered nurses residing in 11 US states. Participants: A total of 16,144 women from the Nurses’ Health Study, aged _70 years, who underwent cognitive testing a total of 4 [...]

Dose response effects of supplementation with calcifediol on serum 25-hydroxyvitamin D status and its metabolites: A randomized controlled trial in older adults

Clinical Nutrition | 26-03-2017 | Abstract Background & aims: Oral supplementation with vitamin D is recommended for older adults to maintain a sufficient 25-hydroxyvitamin D (25(OH)D) status throughout the year. While supplementation with vitamin D2 or D3 is most common, alternative treatment regimens exist which require further investigation with respect to increasing 25(OH)D concentration. We investigated the doseeresponse effects of supplementation with calcifediol compared to vitamin D3 and assessed the dose which results [...]

Activation-Induced Autophagy Is Preserved in CD4+ T-Cells in Familial Longevity

The Journal of Gerontology  | 09-05-2017 | Abstract As with many other tissues and organs, the immune system is also affected by age. Immunosenescence is characterized by a decreased ability of immune cells to mount a productive response upon exposure to new antigens. Several studies have reported that members of families with exceptional longevity show improved immune function, which might contribute to the increased life- and health-span observed in those families. Autophagy is [...]

Cellular senescence drives age-dependent hepatic steatosis

Nature Communications | 13-06-2017 | Abstract: The incidence of non-alcoholic fatty liver disease (NAFLD) increases with age. Cellular senescence refers to a state of irreversible cell-cycle arrest combined with the secretion of proinflammatory cytokines and mitochondrial dysfunction. Senescent cells contribute to age-related tissue degeneration. Here we show that the accumulation of senescent cells promotes hepatic fat accumulation and steatosis. We report a close correlation between hepatic fat accumulation and markers of hepatocyte senescence. The [...]

Later-life mortality and longevity in late-18th and 19th-century cohort: Where are we now, and where are we heading

European Historical Population Samples Network  | 31-01-2017 | Abstract The limits to human lifespan are a widely discussed topic. Yet, later-life mortality and longevity are generally studied from a genetic perspective, while the social dimension has received less attention. This paper gives a systematic overview of trends in later-life mortality and longevity for cohorts that were born in the late 18th and 19th century, and shows that the average population and the top survivors [...]

Targeted Apoptosis of Senescent Cells Restores Tissue Homeostasis in Response to Chemotoxicity and Aging

Cell  | March 2017 | Abstract The accumulation of irreparable cellular damage restricts healthspan after acute stress or natural aging. Senescent cells are thought to impair tissue function and their genetic clearance can delay features of aging. Identifying how senescent cells avoid apoptosis allows for the prospective design of anti-senescence compounds to address whether homeostasis can also be restored. Here, we identify FOXO4 as a pivot in senescent cell viability. We designed a FOXO4 peptide [...]

Employing biomarkers of healthy ageing for leveraging genetic studies into human longevity

Experimental Gerontology  | 29-06-2016 | Abstract: Genetic studies have thus far identified a limited number of loci associated with human longevity by applying age at death or survival up to advanced ages as phenotype. As an alternative approach, one could first try to identify biomarkers of healthy ageing and the genetic variants associated with these traits and subsequently determine the association of these variants with human longevity. In the present study, we used this [...]

Resistance Training Increases Skeletal Muscle Capillarization in Healthy Older Men

Medicine and science in sports and exercise  | November 2016 |  Abstract: PURPOSE: Skeletal muscle capillarization plays a key role in oxygen and nutrient delivery to muscle. The loss of muscle mass with aging and the concept of anabolic resistance have been, at least partly, attributed to changes in skeletal muscle capillary structure and function. We aimed to compare skeletal muscle capillarization between young and older men and evaluate whether resistance-type exercise training increases [...]

Expression of protocadherin gamma in skeletal muscle tissue is associated with age and muscle weakness

J Cachexia Sarcopenia Muscle  |  December 2016 |  Abstract BACKGROUND: The skeletal muscle system plays an important role in the independence of older adults. In this study we examine differences in the skeletal muscle transcriptome between healthy young and older subjects and (pre-)frail older adults. Additionally, we examine the effect of resistance-type exercise training on the muscle transcriptome in healthy older subjects and (pre-)frail older adults. METHODS: Baseline transcriptome profiles were measured in muscle [...]

Extensive Type II Muscle Fiber Atrophy in Elderly Female Hip Fracture Patients

 J Gerontol A Biol Sci Med Science  | November 2016 |  Abstract: Background: Sarcopenia, or the loss of muscle mass and strength, is known to increase the risk for falls and (hip) fractures in older people. The objective of this study was to assess the skeletal muscle fiber characteristics in elderly female hip fracture patients. Method:Percutaneous needle biopsies were collected from the vastus lateralis muscle in 15 healthy young women (20 ± 0.4 years), [...]
