Controls are adults with no pancreatic cancer (excluded by a 6 months old computed
The World Health Organization (W.H.O). defines oral potentially malignant disorders (OPMDs) as "A histologically proven lesion that is associated with a significantly increased risk of malignant transformation."Oral leukoplakia is the most commonly occurring oral potentially malignant disorder.
Eligible subjects will provide a baseline 24 hour urine sample. Study cigarettes spiked with labeled NNK will be provided to the subjects to smoke over a 7 day period. During this time, 24 hour urine samples will be collected over days 5, 6 and 7 on study cigarettes. Blood will be drawn on days 6
Thirdhand cigarette smoke is the smoke chemicals that persist in the environment after smoking. Indoors, they can be found both on surfaces and in the air. Thirdhand smoke derives from secondhand smoke and contains the chemicals that stick to surfaces, are re-emitted into the air and that form by
Determine whether nutritional supplement sulforaphane (SFN) is safe to administer to breast cancer patients undergoing doxorubicin (DOX) chemotherapy. The investigators have identified biomarkers for presymptomatic detection of DOX cardiotoxicity in breast cancer patients and reported that SFN
This innovative research project will assess the acceptability among committed smokers of switching to unfiltered cigarettes from filtered cigarettes and compare the measurement of exposure to nicotine and carcinogens after such a switch from filtered to unfiltered cigarettes. Such research will
Extracellular vesicles (EVs) include a variety of nanoscale membranous vesicles (exosomes, microvesicles, microparticles). EVs are released into the interstitial fluid from a wide variety of normal or diseased cells.
Analysis of EVs and their content maybe useful as disease biomarkers as they
Tobacco smoking is the leading cause of head and neck cancer in the United States and a significant portion of head/neck cancer survivors continue to smoke even though smoking negatively impacts their clinical outcomes and increases chance of recurrence. Two tobacco chemicals, NNK and nicotine, are
Among the Gulf Countries Collaboration Council (GCCC) states, HNC account for 11.5 per 100,000 population. The incidence of HNC in Kuwait is 3.8 per 100,000 population. This, as an example, accounts for about 12.7% of all cancer cases during the period from 1993 to 1999.

In addition to examining characteristics of pregnant e-cig users as well as patterns of their product use, this study is innovative in several ways. First, it is the first known study to examine toxicant exposure to cigarettes and e-cigs in a sample of pregnant smokers who are using these products.
The 2014 Surgeon General's Report on the Health Consequences of Smoking concludes that changes in the physical design of cigarettes have caused an increased risk of developing lung cancer. One prominent cigarette design feature is filter ventilation, which has become increasingly common since the
