Gastric Cancer Associated with Helicobacter Pylori

In spite of a decline in incidence and mortality of gastric cancer over the last decades, it is still the fourth most common cancer and the second most common cause of cancer death in the world. The differences in prevalence of gastric cancer have been explained as a multifactorial process with an interaction involving both infection with Helicobacter pylori as a triggering factor and host genetic susceptibility as an important explanation for interindividual variation in gastric cancer risk. At present, there is no definitive host genetic risk marker, and evidence suggests that each proposed host risk factor should be evaluated in specific ethnic populations to define its importance. In this review, we discuss the most relevant up to date data on genetic polymorphisms that have been associated with an increased risk for the development of gastric cancer, its potential role in the development of this neoplasia, and its interplay with the virulence factors of the bacteria

How Does the Thyroid Function Affect the Sport?

Some authors have speculated that the symptomatic chain of the thyroid function was linked to the alteration of basal metabolism that occurs during the Dysthyroidism. Other researchers, though, suggest that changes of the cardiovascular apparatus ought to be put in relation to a direct action of thyroid hormones on the heart. However, it can be stated that in the determination of the heart phenomenology, during the thyroid disease, are implicated both direct and indirect effects.Keywords: thyroid function, cardiovascular apparatus, thyroid hormones, symptomatic/symptomatic patients, etc.

Teratogenesis

The world today is experiencing a period of rapid technological versatile. Unfortunately, this development has its negative consequences. Dumping in an atmosphere of chemical waste, except to other effects, not pass without consequences on human health and in particular in the period in which it is being formed and developed a future individual, i.e. during pregnancy. It is known that the first quarter of this period is sensitive because it is precisely this period in which take originated all the structures of the developing organism. Fall into contact with substances assigned in this period, resulting in serious consequences in the future of the individual to be born. In some cases turns out that the substances are considered as medications may have teratogenic effects. Some are known and are removed from use, some are under study, but may have also some widely used and that can be such.Keywords: teratogenic problems, malformations, toxicology, growth delay, cell death, etc.
