TL;DR: In addition to the normal complement of plant cell enzymes, tea leaf contains an active polyphenol oxidase which catalyzes the aerobic oxidation of the catechins when the leaf cell structure is disrupted during black tea manufacture as mentioned in this paper.

TL;DR: The results suggest that Factors influencing adoption are different for men and women, and there may be different factors influencing adoption versus maintenance of vigorous physical activity.

TL;DR: The results showed that both yields of polyphenol extract and antioxidant activities varied with different tea processing methods, and it was found that (-)-epigallocatechin gallate, (--epig allocatechin, and (-)-epsic acid inhibited soybean lipoxygenase at the IC50 values ranging from 10 to 20 microM.

TL;DR: The mortality rate was higher (not statistically significant) among persons drinking no tea or less than one cup compared with persons drinking one or more cups/day, and this applies to men and women and to coronary heart disease and all-cause mortality.

TL;DR: It was concluded that behavior change strategies to prevent malignant melanoma of the skin are warranted.

TL;DR: Smoking is a detriment to physical fitness even among relatively young, fit individuals, and study findings suggest that smokers will have lower physical endurance than nonsmoker, even after differences in the average exercise levels of smokers and nonsmokers are taken into account.

TL;DR: The higher NK cell activity among individuals reporting good lifestyle practices may reflect an increase in the cytolytic potential ofNK cell activity within the CD16+, CD57- subset.

TL;DR: It is suggested that tea components possess antimutagenic and anticarcinogenic effects, and that they could protect humans against the risk of cancer by environmental agents.

TL;DR: Serum cholesterol levels were inversely associated with traditional Japanese dietary habits and positively associated with Westernized habits, and additional adjustment for these dietary variables did not alter the inverse relation between green tea and total cholesterol.

TL;DR: The main constituent of Japanese green tea, EGCG, is a practical cancer chemopreventive agent available in everyday life and is believed to be a nontoxic compound.

TL;DR: Findings are used to highlight the critical importance of physician behavior in the secondary prevention of breast cancer in older women and to identify types of patients whose needs for screening are most likely to be overlooked by physicians.

TL;DR: Housing tenure in Scotland is found to be the most discriminatory measure of social status in relation to coronary heart disease, using a cross-sectional sample of 10,359 men and women.

TL;DR: Observations indicate a relationship between behavior change and physiologic changes achieved in a total school health promotion to reduce cardiovascular risk.

TL;DR: Results indicate that this legislative initiative was insufficient to reduce adolescent tobacco use statewide during the 5-year study period, and suggest that even more intensive efforts may be required to effect widespread reductions in adolescent Tobacco use.

TL;DR: The mechanism of inhibition may not have resulted from direct interaction between E GCG and the mutagens, but rather from indirect interception of mutagen action by EGCG.

TL;DR: The results show that minors can purchase cigarettes in all types of businesses, even those characterized as "adult" locations, and support stringent and universal controls over the sale of cigarettes as an essential part of any tobacco use prevention strategy.

TL;DR: The results suggest that blacks living in the South, particularly black women, have lower levels of leisure time physical activity compared with their white counterparts after control for several important confounders.

TL;DR: Rural women were found to have the same basic knowledge of breast cancer or perceptions of barriers to mammography, but had more negative attitudes about breast cancer itself and particular program delivery strategies when planning for provision of breast screening information and service to the large subgroup of rural women.

TL;DR: It is indicated that while physicians support exercise for health promotion and rehabilitation, greater emphasis needs to be placed on physician involvement in promoting and/or prescribing exercise.

TL;DR: Predictors of higher levels of motivation to quit smoking included higher socio-economic status, maleness, lower levels of self-reported nicotine dependence, and stronger perceptions that smoking was against the social norms of the workplace.

TL;DR: The results suggest that feelings of deprivation should be avoided, perhaps by use of low-fat substitutes, by those attempting to lower their dietary fat and that more research is needed on the development of a distaste for fat among individuals who adopt low-Fat diets.

TL;DR: Male urban civil servants appeared to have a risk for hypertension similar to that of U.S. black males, and age, body mass index, alcohol drinking, and other unidentified factors related to higher socioeconomic status were strong determinants of hypertension in this population.

TL;DR: Oral administration of a green tea infusion as the sole source of liquid sustenance to SKH-1 mice inhibited ultraviolet B light (UVB)-induced sunburn lesions, UVB-induced initiation of skin tumors, and nitrosodiethylamine-induced forestomach and lung tumors in A/J mice.

TL;DR: It is concluded that more targeted education in the domain of knowledge would benefit males and those over the age of 59.

TL;DR: These studies suggest that the previous reported anticarcinogenic activity of green tea may be related to its effect on the tumor promotion stage of the cancer process.

TL;DR: The effects of Chinese tea on the occurrence of esophageal tumors induced by N-nitrosomethylbenzylamine (NMBzA) in rats showed the same protective effects of tea treatment, and a significant reduction of O6-methylguanine (MeG) and the ratio of N7-MeG was observed in rats treated with oolong tea and jasmine tea.

TL;DR: Results indicate that the simultaneous intake of teas with food products that are being nitrosated within the stomach of human subjects should exert a protective, beneficial effect.

TL;DR: It is indicated that serum very-low-density lipoprotein (VLDL) levels are directly and independently related to obesity.

TL;DR: It is illustrated that persons from all educational levels can modify their risk for CVD and are of particular importance because of the higher prevalence of CVD risk factors among those with less education.
