--Advances in molecular biology over the past decades have contributed to a profound understanding of the function of genes in the development of diseases. The environment and nutritional factors interact with the genetic background of subject results in development of various diseases including cancer, cardiovascular disease and degenerative nervous disorders. However, the exact mechanisms o...

We show that, in the presence of uncontrolled environmental confounding, joint tests for the presence of a main genetic effect and gene-environment interaction will be biased if the genetic and environmental factors are correlated, even if there is no effect of either the genetic factor or the environmental factor on the disease. When environmental confounding is ignored, such tests will in fac...

Endometriosis is a chronic disease that affects 10-15% of women in their childbearing years and peaks between the ages of 25 and 35. In this disease, the endometrial tissue of the uterus is formed and grows outside of it. Family studies and investigation of twins show that endometriosis is more common in the relatives of the infected individuals. Studies on the role of genetics and the environm...

The main objective of facilities location and service system design is covering of potential customers’ demand. Many location models are extended with the covering objective and considered constraints, details of problem and its different aspects. In this paper the maximal covering location-allocation model for congested system is extended in the competitive environment. In the proposed model, ...

background: the traditional methods of studying the gene-environment interactions need a control group. however, the selection of an appropriate control group has been associated with problems. therefore, new methods, such as case-only design, have been created to study such interactions. the objective of this study was to compare the case-only and case-control designs using data from patients ...
