monozygotic twins are genetically identical individuals who can also be mirror image twins and the differences between them result from environmental factors. current study, monozygotic twins were analyzed in different dentitions of primary, mixed and permanent. as a conclusion, although genetic factors are naturally potent, environmental factors’ role can be increased and weaken the genetic fa...

flow river forecasting plays an important role in designing, management, and utilization of water resources. the main object of the research is to study the possibility of forecasting and monitoring the northern karon rivers (armand and bazfat) discharge by using modern simulation methods. in this research, armand and bazoft discharge variations was investigated. in this regard, monthly data of...

Diabetic retinopathy (DR), a microvascular complication of diabetes in the retina, is one of the leading causes of adult blindness worldwide. Complex interplay of environmental and genetic factors has been known to contribute to its pathology. Variations in several genes have been found to be associated with risk for developing DR in different populations worldwide, which is discussed in this a...

It is generally accepted that autoimmune diseases like multiple sclerosis (MS) arise from complex interactions between genetic susceptibility and environmental factors. Genetic variants confer predisposition to develop MS, but cannot be therapeutically modified. On the other hand, several studies have shown that different lifestyle and environmental factors influence disease development, as wel...
