Aronia berries are a native North American berry with high naturally occurring anthocyanins among other polyphenols. Based on their polyphenol composition, there is growing interest in the potential for Aronia berries to elicit health promoting cardio-metabolic effects. Specifically, Aronia berry extracts, which provide a concentrated source of polyphenols, may improve blood vessel function. Thus, the primary focus of this project is to evaluate the effects of Aronia berry ...
The primary objective of this study is to determine which components of berries improve glucose metabolism and increase fat oxidation in humans.
There is an increasing interest in the effects of various food derived polyphenols on vascular function. Arguably the most well-established vascular benefits are attributed to flavanols from cocoa beans and this has been supported by a successful health claim through the European Food Safely Authority in 2012. Berry fruits are another rich source of polyphenols that have vasoactive properties, and there is a growing body of research exploring these effects in various berries (b...
The aim of the present study is to describe the bioavailability for the proprietary standardized maqui berry extracts Delphinol® and MaquiBright® enriched in anthocyanins and in particular delphinidins. The analyses are based on two selected key substances namely delphinidin-3-glucoside and cyanidin-3-sambubioside and their metabolism to phenolic acids. The bioavailability of anthocyanins specific for Delphinol®/MaquiBright® was analyzed in plasma sample kinetics (at 0h, 0...
The purpose of this clinical study is to evaluate acute effects of plant-based nutritional extracts on adult stem cells, using a randomized double-blinded placebo-controlled cross-over study design.
The main objective of this study is to investigate the effect of a 4-weeks intake of berry peel powder on fasting and postprandial glucose metabolism and inflammatory markers. The berry peel product will be compared with a placebo in a single-blind, cross-over design. Furthermore, inflammation-related peripheral blood mononuclear cells (PBMCs) genes expression, appetite and cognitive performance will be included as a pilot study. Investigators hypothesize that long-term consump...
To determine whether there were differences in the prevalence and extent of atherosclerotic lesions in the coronaries and aortas between Alaskan natives and non-natives, and whether the extent of the lesions was related to omega-3 fatty acids in blood and tissues.
This study examines the impact of a culturally tailored version of contingency management treatment on alcohol in 400 alcohol dependent American Indians and Alaskan Natives. Participants will be recruited from addiction treatment agencies and throughout the community. Those who complete a 4 week induction period will be randomized to receive 12 weeks of contingency management or a non-contingent control condition. Individuals will then be followed for an additional 3-months to...
The purpose of this study is to advance upper limb RMTR for patients recovering from stroke by empowering them through active science participation. By varying the tasks' features and affordances of a platform that combines a low-cost haptic device on one hand, and an online citizen science platform on the other, investigators will evaluate different strategies for social telerehabilitation. the two fundamental modes of social interaction — competition and cooperation — in ...
While low-income midlife and older adults are disproportionately affected by chronic diseases that can be alleviated by regular physical activity, few physical activity programs have been developed specifically with their needs in mind. Those programs that are available typically do not address the recognized local environmental factors that can impact physical activity. This research aims to evaluate the added effects on two-year physical activity levels of a novel citizen sci...
Malnutrition or its risk is common among older people, especially among those receiving home care services. It impairs the quality of life of the older people and results in significant costs to society. To maintain adequate nutrition, increased meal frequency is important. In addition to main meals, regular consumption of tasty, convenient, nutrient- and energy-dense snacks is recommended. The purpose of this study is to investigate the effects of dairy- and berry-based snack ...
Helicobacter pylori (HP) is the major risk factors of gastritis, gastric ulcers, duodenal ulcers, mucosa associated lymphoid tissue lymphoma and gastric cancer. Helicobacter pylori are found in 70-90% of the population in developing countries and in 25-50% of developed countries.
This study will explore scientists opinions and practices regarding the use of population descriptors (e.g., race, ethnicity, ancestry, geography and nationality) to describe a research study population. It will collect genetic researchers opinions, understandings and experiences studying human genetics and genetic variation. Scientists who are a principal investigator or co-principal investigator n a human genetic or genomic study of a common disease with at least preli...
Berries have been shown to improve postprandial glucose and insulin responses to sucrose. During processing and storage of berry products, sucrose is inverted to glucose and fructose. The effects of berries on the glycemic response induced by inverted sugar are not known. The purpose of this study is to determine whether berries are effective in lowering the postprandial glucose and insulin responses induced by inverted sugar.
The Mexican American population in the U.S. is rapidly growing and aging. This project seeks to determine the prevalence and outcomes of cognitive impairment and dementia in Mexican Americans. It also seeks solutions to help patients with cognitive impairment and dementia and their caregivers get the resources they need.
The purpose of this study is to help scientists understand how the gut senses ingested nutrients and what kind of processes take place for their absorption in order to establish the association with diabetes and other metabolic diseases Scientists need human specimens to study.
Heifer Project International is a globally active NGO with more than 400 projects in over 30 countries. The organization uses the introduction of livestock and related training in the development of social capital as tools for poverty alleviation, citizen empowerment, and community development. In a pilot project conducted in 2009-2012, these activities were found to promote some improvement in child health and nutritional status. However, robust enhancement of these important ...
In response to large numbers of senior center clients who suffer untreated depression and the dearth of geriatric mental health providers, the investigators have simplified a Behavioral Activation intervention to match the skill set of age-matched lay volunteers available to senior centers (Volunteer BA). This R34 proposes developmental work on delivering Volunteer BA in senior centers, so as to arrive to a sustainable intervention with standardized procedures. The investigator...
"Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity" (World Health Organization, 1948). Diseases such as HIV/AIDS and Hepatitis-C (HCV) thrive in conditions of poverty and marginalization. Research on the quality of life of people living with HIV/AIDS reveals that unemployed individuals report more depression, anxiety, social isolation, and low self-esteem than employed individuals. Moreover, unemployment is ...
The Blue Sky Project, a 5-year study funded by the Canadian Institutes of Health Research, seeks to examine how genetics and early life experiences work together to cause a person's very first onset of depression by increasing sensitivity to stress.
The proposed project seeks to develop an online self-directed learning (SDL) intervention program that seeks to improve caregiving and self-care skills among ethnic Chinese dementia caregivers. The benefits of such a product may include improved psychological health in caregivers and a reduction in behavioral disturbances among elderly care recipients with dementia.
Rates of suicide among young Alaska Native males are over ten-fold higher than among a similar age cohort in the rest of the United States. A high proportion of these deaths are associated with firearms. Firearms are an important part of the subsistence lifestyle of this population, however restriction of access to guns by youth may be a promising strategy to reduce the risk of suicides in this population. Previous research conducted in the first phase of this project has demo...
