In precision farming, weed detection is required for precise weedicide application, and the of tobacco crops necessary pesticide application on leaves. Automated accurate weeds through aerial visual cues holds promise. Precise in crop field imagery can be treated as a semantic segmentation problem. Many image processing, classical machine learning, deep learning-based approaches have been devis...

background rheumatic diseases are chronic diseases, which may be associated with severe and debilitating pain. objectives the purpose of this study was to examine the prevalence of tobacco and opioid use among rheumatic patients. patients and methods in this cross-sectional study, 1042 patients referred to a major rheumatology clinic of kerman city, in south east of iran, were interviewed. pati...

background: transient and stable transformation of host plants are the common techniques to produce transgenic plants. however, the main drawback of stable transformation is the fact that it takes quite a long time to produce a transgenic line. while, transient gene expression is a quick method to produce recombinant proteins in plants.  objective: the main goal of the present study was to eval...

results based on the results obtained by the applied technique, the presence of carcinogenic compounds, n-nitrosomethyl-vinylamine (162 µg/g), n-nitrosonornicotine (6.3 µg/g), and acetaldehyde (117 µg/g) was confirmed in the sample. objectives the current study aimed to chemically analyze, separate and measure the existing substances in a type of chewing tobacco. materials and methods in the cu...

tobacco smoke contains numerous compounds, many ‎of which are oxidants and capable of producing free radical and enhancing ‎the oxidative stress. the aim of this study was to investigate the effect of cigarette smoking on the erythrocyte antioxidative enzyme activities and the plasma ‎concentration of their cofactors. ‎sixty eight healthy men were enrolled, 32 of whom had never smoked and 36 ha...

context the aim of this review was to examine evidences for the association between smoking and periodontal disease, to discuss possible biological mechanisms whereby smoking may adversely affect the periodontium, and to consider the effect of smoking on periodontal treatment. evidence acquisition a web-based search in pubmed and google scholar was performed to identify publications regarding t...

This cross sectional study was conducted to identify prevalence of different disease symptoms, nutritional and socioeconomic status in women workers working in tobacco processing plants. The survey was done on a sample of 240 (Two hundred and forty) female tobacco workers. The study was done by direct participatory observation method. The target persons were interviewed on the basis of prepared...

To test the hypothesis that caspase-like proteases exist and are critically involved in the implementation of programmed cell death (PCD) in plants, a search was undertaken for plant caspases activated during the N gene-mediated hypersensitive response (HR; a form of pathogen-induced PCD in plants) in tobacco plants infected with Tobacco mosaic virus (TMV). For detection, characterization, and ...

Background: Tobacco is one of the most important causes of morbidity and mortality. Tobacco toll in India has one-fifth of all worldwide death attributed to tobacco. There are 700000 deaths per year due to smoking and 800000-900000 per year to all forms of tobacco use of exposure in India.
