BACKGROUND The attempt to understand the kinetic behavior of nicotine in tobacco will provide a basis for unraveling its energetics in tobacco burning and the formation of free radicals considered harmful to the cigarette smoking community. To the best of our knowledge, the high temperature destruction kinetic characteristics of nicotine have not been investigated before; hence this study is ne...

A 355 cauliflower mosaic virus promoter and a tapetum-specific promoter were used to direct the synthesis in tobacco of preproactinidin and a derivative that lacked a C-terminal extension. Preproactinidin was processed into a form that migrated identically on protein gels with mature actinidin extracted from kiwifruit. This protein was proteolytically active in vitro, and high-level accumulatio...

This study was undertaken to assess the pulmonary and respiratory problems of workers in a zarda factory. A total of 70 permanent zarda workers (50 manufacturing workers and 20 office ones) were studied in a factory in Baguihati, Kolkata, India. The study included (a) completion of a questionnaire (on pulmonary and respiratory problems), (b) measurement of physical parameters, (c) spirometry an...

Subjects and Method: The exposed group consisted of 20 subjects with mena age of 43.4 years. The average duration of their occupational exposure was 19.95 years. The control group consist...

3 Introduction The food processing industry is increasingly becoming an important sector in developing countries for its role in generating employment and attracting foreign investment. During the period 1980-91, the food industry (including tobacco and beverages) grew at a rate of 87% in developing nations (doubling in many Asian countries) compared to only 20% in developed countries. Moreover...

background: training medical students in tobacco prevention and cessation skills is critical to have competent physicians who are prepared to address the grave levels of morbidity and mortality associated with tobacco use. medical students should possess adequate knowledge of the risks of tobacco use and acquire appropriate skills for helping their patients in smoking prevention and cessation. ...

in order to study the effect of methanol on growth and yield of virginia tobacco varieties cocker 347, an experiment was carried out through a factorial experiment in randomized complete block design with 4 replications and 18 treatments. first treatment was spraying time which includes 3 levels, sprayed in the morning (8-10 hours) and noon (12-14 hours) and evening (17-19 hours) and the second...
