Tobacco serine/threonine protein kinase gene NrSTK enhances black shank resistance

Y. - L. Gao, Wang, B. - W., Xu, Z. - L., Li, M. - Y., Song, Z. - B., Li, W. - Z., and Li, Y. - P., Tobacco serine/threonine protein kinase gene NrSTK enhances black shank resistance, vol. 14, pp. 16415-16424, 2015.

A serine/threonine protein kinase gene (NrSTK) was cloned from Nicotiana repanda based on the sequence of a previously isolated resistance gene analog (RGA). Expression of RGA was induced by challenge with the pathogen black shank. The NrSTK gene was predicted to encode a protein kinase that contained an ATP binding site at residues 41-69 and a serine/threonine protein kinase activation sequence spanning the region 161-173.

Assessment of genotoxicity of waterpipe smoking using 8-OHdG biomarker

M. Azab, Khabour, O. F., Alzoubi, K. H., Mahmoud, S. A. H., Anabtawi, M., and Quttina, M., Assessment of genotoxicity of waterpipe smoking using 8-OHdG biomarker, vol. 14, pp. 9555-9561, 2015.

Waterpipe tobacco smoking is increasing in popularity, particularly among young adults. This popularity is related to the lack knowledge regarding the health effects of waterpipe smoking. In this study, we examined the genotoxicity of waterpipe smoking using an 8-hydroxy deoxyguanosine (8-OHdG) assay. Genotoxicity was evaluated in the saliva, urine, and serum of 66 waterpipe adult smokers and 46 healthy nonsmokers. The level of addiction to waterpipe smoking was evaluated using the Lebanon Waterpipe Dependence Scale-11.
