The Bioavailability of Polyacetylenes From Carrots Study

2016-03-04 01:53:32 | BioPortfolio


Polyacetylenes, compounds found naturally in carrots, have shown promising anti-cancer and anti-inflammatory actions in vitro but have not been tested in vivo. To determine whether the polyacetylenes could have an effect in vivo, this study aims to determine whether they are detectible in human biofluids after the consumption of a portion of carrots and whether a difference is seen between a large and small portion.


Volunteers will collect urine samples 24 hours prior to the 'test' day and a stool sample either the night before or the morning of the test session. They will have fasted blood taken before eating a portion of carrots with bread and butter. Further blood samples will be taken at 0.5, 1, 2, 3, 4, 6, 8 and 24 hours. All urine and all stool samples (after 4 hours) will be collected up to 48 hours after the carrot dose. They volunteers will attend two test sessions and will be randomised to receive high and low doses of carrot. At least a week will separate testing sessions.

Medical and Biotech [MESH] Definitions

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.

Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.

Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.

Process of evaluating the health of a patient and determining if they are healthy enough for surgery.

Dietary patterns which have been found to be important in reducing disease risk.
