Preimplantation genetic diagnosis (PGD) represents an alternative to prenatal diagnosis and allows selection of unaffected IVF embryos for establishing pregnancies in couples at risk for transmitting a genetic disorder.

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...

Multiple regression of genetic evaluations for milk yields of first lactations of 159 Holstein bulls on sire, dam, and maternal grandsire evaluations indicates that the weight for estimated transmitting ability of the dam calculated from the first record of the dam and first records of her herdmates is about as theoretically expected and is markedly superior both to estimated transmitting abili...

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...

Plant disease vectors play a critical role in agricultural productivity and ecosystem health. This comprehensive review explores the intricate nature of these their transmitting major plant diseases, including those viral, bacterial, fungal origins. It delves into mechanisms underlying transmission, significant factors that influence vector efficiency. The socioeconomic ecological impacts are h...

kind. I refer to cancer or diseases of the circulation such as strokes, heart attacks, atherosclerosis or pulmonary embolisms. Let me remind you of the 'genetic component' of these commoner diseases. It is now abundantly clear that somatic mutations in specific oncogenes correlate with particular cancers. They are clearly one important factor in the cause of malignancy. And, turning to the circ...
