Allergic airway disease is a term used to describe conditions such as allergic rhinitis and asthma. Among other causative agents, air pollutants and diesel exhaust in particular, have been shown to create and also worsen existing allergic airway disease. These inhaled pollution particles have oxidative properties that drive inflammation-related effects through specific metabolic-associated processes. These processes are not adequately suppressed by current therapeutics. The pur...
Adult participants will apply a broccoli sprout extract-jojoba oil compound to one arm every night under occlusion for 1 week. Jojoba oil alone will be applied to the other arm. At the end of 1 week, a 6mm punch biopsy will be taken from both arms and analyzed via polymerase chain reaction (PCR) and immunohistochemistry for differences in various skin proteins.
The investigators proposed to identify the biological effects of a high-sulforaphane broccoli sprout extract in normal prostate tissue. The investigators hypothesize that consumption of high-sulforaphane broccoli sprout extract every other day will inhibit growth of prostate cancer cells.
The purpose of this research is to examine the effect of a broccoli sprout preparation on specific factors in breast tissue that are related to breast cancer risk and to assess whether sulforaphane a key component of broccoli sprouts increases the levels of protective enzymes in breast tissue. In addition, the investigators will also examine how acceptable the broccoli sprouts preparation is to the study participants.
In Korea, the first-line therapy to treat Helicobacter pylori (Hp) consists of a proton pump inhibitor (PPI) and two antibiotics for one week. But, eradication has become less successful due to low compliance and high resistance to the antibiotics. Therefore, it is necessary to develop new treatment strategies that increase the eradication rate and reduce adverse effects. In vitro study, we previously reported that a broccoli sprout extract containing sulforaphane may prevent l...
Do daily high (4 tablets) or intermediate (2 tablets) administration of the broccoli-based dietary supplement Avmacol® have improved bioavailability over a broccoli sprout beverage rich in sulforaphane and its biogenic precursor, glucoraphanin? The beverage formulation has been used successfully in the investigators' previous intervention studies in regions of China with high levels of air pollution to reduce the body burden of carcinogenic and toxic pollutants. The investigat...
This study is being done to see whether Avmacol®, a dietary supplement made from broccoli sprout and seed extract powder, induces changes in inner cheek cells that may be protective against environmental toxins such as tobacco. There are three main goals of the study: 1. To learn whether the dietary supplement, Avmacol®, can stimulate cheek cells to repair damage from environmental toxins; 2. to learn how the body metabolizes Avmacol®, by measuring its bypr...
The investigators plan to investigate the protective effects of topical sulforaphane-containing broccoli-sprout extracts (BSE) on radiation-induced dermatitis in women undergoing external-beam radiation therapy for breast cancer. Topical sulforaphane induces phase 2 enzymes that are protective against oxidants, electrophiles, and inflammation (Talalay and Fahey, 2001) - all of which are generated by both ultraviolet and ionizing radiation. Previous work from the investigators...
This study will test whether oral intake of a dietary supplement called BroccoMax®, which is a special blend of broccoli extract containing a chemical called sulforaphane (hereafter abbreviated as SFN), may result in changes in chemicals that feed prostate cancer. BroccoMax® is available over the counter.
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 t...
The objectives of the study are 1) to characterize plasma and urinary metabolites that originate from glucobrassicin, 1-methoxyglucobrassicin, 4-methoxyglucobrassicin, and 4-hydroxyglucobrassicin, which are the major indole glucosinolates found in broccoli, and 2) to identify novel plasma and urinary metabolites following broccoli consumption that may have roles in reducing the risk of cancer.
The study hypothesis tested is that broccoli sprouts are effective at altering the urinary levels of metabolites of the hepatocarcinogen aflatoxin B1 and of the air-borne pollutant phenanthrene in residents of Qidong, PRC, where exposures are unavoidable and high. The study will evaluate which of two formulations of broccoli sprouts beverage, glucoraphanin-rich or sulforaphane-rich, exhibits the best bioavailability and is most effective at modulating the biomarkers.
Avmacol is an over-the-counter dietary supplement containing broccoli seed and sprout extracts in tablet form, hypothesized to activate protective cellular pathways including detoxication.
