INTRODUCTION Drug overuse is a serious problem for health care, and one of the biggest problems for the socio-economic well-being of different communities. The elderly tend to use more drugs due to changes in their cognitive and physiological factors. One of the best ways to evaluate the health level of elderly people is to evaluate their self-medication. This study was conducted to investigate...

We investigated whether development of resistance to a Bt crop in the presence of a natural enemy would be slower than without the natural enemy and whether biological control, in conjunction with a Bt crop, could effectively suppress the pest population. Additionally, we investigated whether insecticide-sprayed refuges of non-Bt crops would delay or accelerate resistance to the Bt crop. We use...

The study of latitudinal gradients can yield important insights into adaptation to temperature stress. Two strategies are available: resistance by limiting damage, or tolerance by reducing the fitness consequences of damage. Here we studied latitudinal variation in resistance and tolerance to frost and heat and tested the prediction of a trade-off between the two strategies and their costliness...

Fusarium wilt caused by Fusarium oxysporum f.sp. Lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. In order to increase the tolerance to this disease, a triple structure containing PR1, chitinase and glucanase genes controlled by 35S promoter was transferred to tomato. Eight days after planting on pre-culture me...

Introduced plants often face new environmental conditions in their non-native ranges. To become invasive, they need to overcome several biotic and abiotic filters that may trigger adaptive changes in life-history traits, like post-germination processes. Such early life cycle traits may play a crucial role in the colonization and establishment success of invasive plants. As a previous study reve...

The increasing use of nanofertilizers in modern agriculture and their impact on crop yield pest management require further research. In this study, the effects nano-Fe, -Zn, -Cu (which are synthesized based nanochelating technology), urea (N) fertilizers antioxidant activities wheat plants (cv. Chamran), green aphid Schizaphis graminum (Rondani) investigated. authors observed highest levels phe...

When the grief around poet and writer is fragile when life filled with sorrow bitterness, then tyranny oppression become ordinary profession of people in several cases; creator, literary artistic works as a conscious connected stratum society do not became only spectators, instead help transcendent thoughts creative minds, they create valuable creation to be mirror dreams desire people. On othe...

ABSTRACT- The increasing population and the pastures inability to meet food needs in livestock have led to the increase of cultivates forage plants. In order to evaluate the effect of plant growth promoting rhizobacteria (PGPR) and alfalfa (Medicago sativa) extract on the growth and concentration of macronutrient and micronutrient contents of  forage sorghum (Sorghum vulgare), an experiment was...
