Filter by:The purpose of the study is to study the potential anti-inflammatory- and metabolic effects of polyphenols and dietary fibres in a product based on a mixture of several Swedish berries and vegetables that is known to have high amounts of polyphenols and other anit-oxidants. In addition the purpose is to investigate the effects on cognitive functions of the berry product.
The purpose of this study was to identify the effects and the efficiency of an adapted physical activity program as regards the physical condition of older Brazilian women.
It has well known that diets rich in fruits, vegetables and cocoa products are associated with positive health benefits and these positive effects have been shown to be due to compounds they contain called flavanols. Flavanols have been shown to exert their positive effects by indirectly increasing nitric oxide (NO) bioavailability. NO is a potent vasodilator that is believed to play a role in increasing blood flow to active muscle during exercise. This regulatory process is impaired with healthy aging. The underlying premise to this study is that if NO bioavailability can be increased following flavanol ingestion, will there be a restoration of blood flow during exercise in older individuals? Accordingly, the first part of this research project will compare the acute vascular effects of flavanol ingestion between a young and old group. The investigators have hypothesized that both groups will show an improvement in blood flow to active muscle during exercise, though the magnitude of the change will be greater in the older group. The second part of this project will look at the effects of 4 weeks of daily flavanol ingestion in the old group. The investigators hypothesize that subjects will demonstrate an improvement in blood flow to active muscle during exercise after the 4 week intervention and that the magnitude of the change will be greater than the acute effects. Findings from this proposal will provide evidence for the efficacy of flavanols to be used (as a simple and safe lifestyle intervention) to reverse or combat impaired blood flow regulation in older individuals.
Millions of diverse Veterans live with severe and chronic illness for which they will face complex, ongoing decisions. Although the VHA has been at the forefront of patient-centered chronic care, interventions to prepare Veterans for complex decision-making over the course of chronic illness are lacking. This proposal addresses this gap by testing the efficacy of a novel preparation guide designed to prepare Veterans to communicate with their surrogates and to work with clinicians to make complex, ongoing decisions. The multi-media guide teaches communication and preparation skill behaviors (e.g., how to choose a surrogate and ask clinicians questions) in a culturally appropriate, easy-to-use format (targeted to a 5th grade reading level). This study aims to provide an impetus for changing the paradigm of advance care planning policies within the VA by moving beyond documentation of end-of-life wishes to the activation of Veterans to participate in ongoing communication of their values and goals - a process that is essential to fully realize patient-centered care.
The purpose of this study is to test if an 8-week mindfulness meditation training (vs a wait-list control condition) program reduces neurobehavioral reactivity and improves affect regulation in a sample of older adults, as measured by functional magnetic resonance imaging. Additionally, we will examine if mindfulness meditation training reduces loneliness and markers of chronic inflammation.
The aim of this study is to assess subjects' satisfaction linked to the pan facial management of rejuvenation with injections of Azzalure® and Restylane® fillers. This will be an open, multi-centre study.
Accumulation of damaged proteins is thought to underlie many degenerative conditions, including aging, diabetes, Alzheimer's disease, cataracts, and others. Over time, proteins can be irreversibly damaged by a variety of factors, such as reactive oxygen species, and without timely degradation they can accumulate and aggregate. We believe this can contribute to the development of chronic degenerative disorders. The purpose of this study is to develop a novel methodology for measuring protein accumulation and test it in two groups of people: young (18-30 years) and old (≥65 years). This methodology will require that people drink a solution of essential amino acids that includes isotopically labeled L[ring-13C6]phenylalanine. We will then collect blood and muscle samples, to isolate plasma and skeletal muscle proteins. Participants will return to the study center four more times on a weekly interval. We hypothesize that older proteins, which persisted in circulation and accumulated over time, will have a higher degree of post-translational oxidative damage than newly synthesized proteins.
The goal of this project is to understand the effect of regular practice of long distance running on the posture and movement control of older adults. For such, the investigators will conduct an experiment with longitudinal design where sedentary elderly individuals will be trained in long distance running for about 4 months.
The investigators propose to test the hypothesis that a six-month intervention of combined fitness and cognitive training in the form of dancing will have a significant positive effect on a variety of executive control and memory processes as well as brain structure and function as compared to a non-aerobic strength and balance control/comparison group. Additionally, these two groups will be compared to walking groups in which one of the walking groups will also be provided with a daily, liquid, milk-based nutritional supplement.
Patients presenting to the clinic for treatment of moderate to severe Nasolabial folds will be recruited to receive either ELAPR002b or ELAPR002d for the treatment of one Nasolabial fold and Juvéderm® Ultra Plus for the treatment of the second, opposite Nasolabial fold.
