Filter by:This randomized pilot clinical trial studies nicotine delivery from novel non-tobacco electronic system (ENDS) in smokers. Studying the levels of nicotine delivered by various types and brands of ENDS to the bloodstream, and comparing this to the levels delivered from conventional cigarettes (the participant's own brand) may help provide information about the use of nicotine-containing products that may help inform/reform current tobacco policy, practice, and harm reduction approaches.
This randomized pilot research trial studies how well Eat, Move, Live (EML) works in reducing chronic disease risk in medically vulnerable communities. Obesity, unhealthy diet, and physical inactivity are linked to increased cancer risk, especially hormone-related cancer (example, breast cancer). Improving healthy lifestyle practices, namely increasing physical activity and encouraging healthy eating behaviors may reduce the risk of getting cancer and chronic disease.
This randomized clinical trial studies the effects of black raspberry compounds (phytochemicals) on the bacteria in the mouth (oral microbiome) of current smokers and non-smokers. The oral microbiome protects the body from pathogenic bacteria. Smoking alters the oral microbiome and may increase the susceptibility to cancer by modulating normal host-bacteria interactions. Black raspberry phytochemicals may protect the oral microbiome of smokers and may lower their risk of developing oral cancer.
This randomized phase II trial studies how well carrageenan-containing gel (vaginal gel) works in reducing the rate of human papilloma virus (HPV) infection in healthy participants. Carrageenans, which are naturally derived from seaweed, are enhancements to natural lubrication and may be effective in blocking HPV infection.
The purpose of this study is to compare three lipidic forms of DHA in their metabolic pathway in human by using 13C labeled molecules. The circulating form of DHA plays a major role in his cerebral incorporation. The aim of this research is to confirm that some lipidic forms are best carriers for the cerebral incorporation in studying 13C-DHA distribution in plasma lipids and blood cells.
A pilot study has been designed to determine (primary objective) if three brief interventions with three oral BSE regimens will alter mRNA biomarkers of Nrf2 pathway signaling, including NQO1, GSTs and AKRs, in the oral mucosa of healthy subjects. Quantitative distribution data and preliminary effect size for specific Nrf2 targets, as measured in serial buccal cell scrapings, will be determined during the course of 3-day exposures to three BSE regimens. These data will inform the design of a randomized, phase II chemoprevention trial in patients with HPV-negative HNSCC. Ten healthy volunteers will be recruited for this pilot study, Age ≥ 18 years, both male and female: 1) The non-cancer population presenting to the University of Pittsburgh Eye and Ear Institute or the Hillman Cancer Center. This may include patients with benign disease or their friends/family members, or friends/family members of patients with cancer; 2) Professionals, staff, or students at the University of Pittsburgh.
This randomized phase I trial studies the side effects and best dose of retinoid 9cUAB30 in preventing cancer in healthy volunteers. The use of retinoid 9cUAB30 may keep cancer from forming in healthy volunteers.
This randomized pilot clinical trial studies the use of physical activity in promoting the discontinuation of the habit of smoking (smoking cessation) in African Americans. Participating in physical activity during an actual smoking quit attempt may work better in helping African Americans stop smoking.
The aim of the present study is to determine the extend to which osteopathic manipulative treatment (OMT) is effective on a sample of healthy subjects in changing high frequency (HF) parameters.
A database (Snapfish) has been generated at Sensimed compiling all data acquired up to now on healthy volunteers and patients with glaucoma. However, healthy subjects were much younger than glaucoma patients. Additionally, the number of glaucoma patients in Snapfish database was almost twice higher than the number of healthy subjects. As it is generally accepted that intra ocular pressure (IOP) in the aging population is higher than IOP in young adults it is of interest to evaluate the 24-hour IOP pattern of older healthy subjects. Furthermore, improving our knowledge of the "healthy" 24-hour IOP pattern in comparison to glaucoma profiles would be beneficial for management of glaucoma.
