Aims: Today, the prevalence of tobacco smoking among students is increasing. Therefore, the purpose of the present study was to determine the factors related with tobacco smoking among students using extended theory of planned behavior. Instrument & Methods: This cross-sectional descriptive-analytical study was conducted on 360 students of Universities of Malayer city who were selected by stra...
Ascorbate oxidase (AO) plays an important role in cell growth through the modulation of reduction/oxidation (redox) control of the apoplast. Here, a cotton (Gossypium hirsutum) apoplastic ascorbate oxidase gene (GhAO1) was obtained from fast elongating fiber tissues. GhAO1 belongs to the multicopper oxidase (MCO) family and includes a signal peptide and several transmembrane regions. Analyses o...
In present study IRAP and REMAP markers were used to assess genetic diversity levels in 45 genotypes of different types of tobacco germplasm, including burley, flue-cured and oriental tobacco that out of 20 composition primers, 5 IRAP primersand 9 REMAP primers produced scorable and polymorphic banding patterns. Totally from 188 amplified loci, 153 loci were polymorph. RTR-10 and RTR-1 with 22 ...
Background and purpose: Tobacco use has an increasing trend. This study aimed at comparing the processes of motivation theory in the prediction of tobacco use in male high school students in Noshahr, Iran. Materials and methods: This cross sectional study was carried out in 440 high school students in Noshahr. The subjects were chosen through stratified random sampling. Data was collected us...
Transported l-[(35)S]cysteine was rapidly metabolized by cultured tobacco cells when supplied to the cells at 0.02 millimolar or 0.5 millimolar. The internal cysteine pool was expandable to approximately 2400 nmoles per gram fresh weight.The (35)S label derived from cysteine was found in several metabolites. The amount of label in glutathione and sulfate was directly proportional to the interna...
An endopolygalacturonic acid trans-eliminase (EC 4.2.2.2), released by osmotic shock of Erwinia rubrifaciens cells, has been purified to near homogeneity (3, 100-fold) by column chromatography on diethylaminoethyl-cellulose, phosphocellulose, and hydroxyapatite-cellulose followed by isoelectric focusing. It has a molecular weight of 41,000, s20,w of 3.09S, an isoelectric point of pH 6.25, pH op...
The Tobacco Convention was adopted by the World Health Organization (WHO) in 2003. Nikogosian and Kickbusch examine the five potential impacts of the Tobacco Convention and its Protocol on public health. These include the adoption of the Convention would seem to unlock the treaty-making powers of WHO; the impact of the Convention in the global health architecture has been phenomenal globally; t...
This research was done aimed to investigation the effective factors on production skills of tobacco growers in Mazandaran province. This is an applied study based on descriptive-correlation method. Statistical population of this research consisted of 1500 tobacco growers of Mazandaran province, and 306 people were selected based on Morgan table. Content validity of the questionnaire was determ...
Introduction: Environmental tobacco smoke (ETS) exposure is a threat for health worldwide. The aim of this study was to determine the environmental tobacco smoke (ETS) exposure in people over 15 years old in Bandar Abbas, Iran. Methods: In this cross-sectional study a total of 387 subjects were selected by cluster sampling method. Data were collected by a questionnaire including demograph...
We have characterized the biochemical nature and the function of PsbZ, the protein product of a ubiquitous open reading frame, which is known as ycf9 in Chlamydomonas and ORF 62 in tobacco, that is present in chloroplast and cyanobacterial genomes. After raising specific antibodies to PsbZ from Chlamydomonas and tobacco, we demonstrated that it is a bona fide photosystem II (PSII) subunit. PsbZ...
