Filter by:Recent work in the investigators laboratory has examined the ability of a non-invasive 13CO2 breath-test to assess differences in amino acid oxidation rates and net balance in young healthy males following protein feeding and resistance exercise. The investigators aim to test the efficacy of this non-invasive 13CO2 breath-test to assess for differences in anabolic sensitivity between young and older adults following an acute period of habitual and reduced physical activity.
Normal aging is associated with a progressive decline in cognitive functions, especially memory. This decline in cognitive function can negatively impact the quality of life of older adults. Although there are currently few possibilities to prevent and/or slow the signs of cognitive decline, both those associated with age and neurodegenerative pathologies, one of the non-invasive brain stimulation techniques that has gained attention in recent years is Transcranial Direct Current Stimulation (tDCS). tDCS is a technique based on the application of a low-intensity (< 2 mA) direct electrical current between two large-area electrodes placed on various surface areas of the head. Moreover, according to safety-related meta-analyses it is a very safe technique, without any major side effects, provided that internationally established safety protocols are taken into account in its application. This technique has recently been investigated as a potential treatment for both healthy elderly people and people with mild cognitive impairment and Alzheimer's disease in several cognitive variables, having shown encouraging results in working memory learning curves, modulation of plasticity and recognition tasks. This project aims to implement an intervention using transcranial direct current stimulation in healthy older adults, MCI and AD. The main objective is to test if there is an improvement in cognitive efficiency and if the changes are maintained over time (1 month). For this purpose, the effect of the technique will be studied on participants assigned to treatment and control groups, analyzing the possible modifications in the following cognitive variables: cognitive plasticity and learning potential, recognition and familiarity and false alarms.
This study will focus on improving brain health through dietary modification of added sugars in middle aged adults (50- 64 years old). Participants will be fed two 10-day diets (one diet containing 5% of total energy from added sugars and one diet containing 25% of total energy from added sugars) and examine blood vessel function, hippocampus structure using a MRI, and memory performance.
The investigators will assess feasibility and acceptability of the Tele-Tai Chi (TC) intervention; explore changes in clinically relevant outcome measures including: physical activity, self-efficacy, quality of life, cognitive function, balance, gait, and evaluate changes in TC proficiency. To achieve this, the investigators are running a single-arm study for older adults that involves a 12-week home-based Tai Chi intervention. Study participation includes four remote and/or in-person (at Spaulding Rehabilitation Hospital) visits to evaluate study participants (mobility tests and questionnaires).
The study was designed as a randomized, placebo-controlled trial with follow-up at 3 months. The study is in accordance with the Declaration of Helsinki and was approved by the Institutional Bioethical Committee of the National Hellenic Research Foundation. All the study participants received informative material, filled a questionnaire regarding the self-assessment of their health status and nutritional habits, and signed their written informed consent. In total, excluding the participants that did not return for the follow-up (dropouts), 122 apparently healthy volunteers of age 29-85 were followed, with 43 of them being randomly assigned in the placebo subgroup and 79 receiving the composition of the present invention.
GERAS DANcing for Cognition and Exercise (DANCE) is a therapeutic mind-body program for older adults (aged 60+) developed with rehabilitation and geriatric medicine expertise at the GERAS Centre for Aging Research at Hamilton Health Sciences and McMaster University. This study will examine if a virtual dance program is feasible for older adults and if dancing at home can benefit mind-body health, self-confidence, and mood.
The primary purpose of the present study is to evaluate the effects of MelaGene on anti-aging and anti-oxidant.
The complexities of the immune system make measuring the impact of dietary interventions upon its function challenging. The immune system is highly responsive to environmental influences, including the diet. An individual's diet provides the energy required to mount a strong and protective immune response, the building blocks required for synthesis of immune mediators such as antibodies and cytokines, and can also indirectly affect immune function via changes in the gut microbiome. Immune function varies across the lifecourse, with a well understood decline in immune function with age, resulting in impaired vaccination responses and an increased risk of infections and of severe complications and mortality arising from common communicable diseases such as influenza. This impaired immunity with ageing is known as immunosenescence and this affects both innate and acquired arms of the immune system.
To fill up the research gaps and build up a healthcare service model for geriatric trauma patients, this two-stage study aims to (a) develop geriatric trauma Artificial Intelligence (AI) prediction models by comparing the outcomes from clinical assessment and AI joint images; and (b) examine the long-term effects of an innovative health service program in geriatric trauma patients.
