چکیده
Oral cancer incidence rates rose dramatically during the twentieth century in the United States and Europe, especially among individuals under the age of 60 years. Although influenced by age, sex, and country of origin, incidence trends were most strongly affected by elevated risk among individuals born after approximately 1915. This cohort effect was indicative of strong behavioral influences on oral cancer risk. In this article, associations between oral cancer risk and established behavioral risk factors including alcohol and tobacco use are reviewed. Additionally, possible associations between oral cancer risk and oral hygiene, diet, nutritional status, and sexual behavior as well as the influence of genetic factors on oral cancer risk are considered. Special emphasis is placed on evaluating possible risk differences in individuals above and below the age of 45 and in users and nonusers of alcohol and tobacco. VC 2007 Wiley Periodicals, Inc.

متن کاملReview Paper: A Review on Brain Stimulation Using Low Intensity Focused Ultrasound
Brain stimulation techniques are important in both basic and clinical studies. Majority of well-known brain stimulating techniques have low spatial resolution or entail invasive processes. Low intensity focused ultrasound (LIFU) seems to be a proper candidate for dealing with such deficiencies. This review recapitulates studies which explored the effects of LIFU on brain str...
متن کاملCommon Statistical Pitfalls in Basic Science Research
T he analysis of clinical samples, population samples, and controlled trials is typically subjected to rigorous statistical review. This fact is understandable, given that the results of clinical investigation will often be used to inform patient care or clinical decision making. One would not want to predicate patient advice on research findings that are not correctly interpreted or valid. For...
متن کاملApoptotic and Autophagic modulation by nicotine
Cigarette smoking is growing and nicotine is considered as the most adverse agent in the cigarette smoking. Nicotine is an alkaloid and forms 90% of alkaloids of cigarette. Nicotine is accountable for creating disorders and cancers such as lung cancer, heart disease and chronic lung disease.

متن کاملThe essential role of basic science in medical education: the perspective from psychology.
Probably ever since the Flexner report endowed basic scientists with a central role in the education of doctors, the same basic scientists have been engaged in active, but circular, debates about why basic science really is essential to medical education. The arguments are generally at the theological level and can easily be dismissed by critics as self-serving. There is little evidence in the ...
