introduction and aims: do h. pylori isolates from normal and dyspeptic patients have similar genetic profiles? since genotype variation occurs within h. pylori population with high frequency, it is tempting to exploit techniques such as rapd-pcr to examine the possible correlation between specific h. pylori genotypes and different peptic diseases. in this study, h. pylori isolates from differen...

age-related macular degeneration (amd) is the leading cause of blindness in old subjects. it is a multifactorial disease with both environmental and genetic factors playing some role in its pathogenesis. similar to many other genetic diseases, the inheritance pattern of amd does not fit into simple mendelian rules. these diseases are caused by the presence of multiple genetic factors and are ca...

in general, both common illnesses and rare diseases can develop in people and their relatives in families. therefore, taking family history is an effective screening tool to detect such diseases and patients should be aware of its importance in families’ health with updating information in regular visiting. for more information on identifying the genetic pattern of diseases, in this article, we...

complex inherited diseases affected by an interaction between collective effects of the genotype at one or multiple loci either to increase or to lower susceptibility to disease, combined with a variety of environmental exposures that may trigger, accelerate, exacerbate, or protect against the disease process. the new aspects of genetic techniques have been opened for diagnosis and analysis of ...

compelling evidence suggests that the oxidative stress plays a key role in the pathophysiology of cardiovascular disease (cvd). superoxide dismutase (sod) enzymes play a major role in detoxification of reactive oxygen species and protection against oxidative stress. we examined the possible association between a 50-bp insertion/deletion in the sod1 promoter 1684-bp upstream of the sod1 atg with...
