Search Results For Atomic Hearts


It has been demonstrated that exposure to atomic bomb radiation appears to be associated with an increased risk of ischemic heart disease (IHD). In addition, atomic bomb radiation dose is associated with many of the IHD risk factors such as high blood pressure, hypertension, high cholesterol level, inflammatory markers, and aortic arch calcification. Because visceral fat accumulation or metabolic syndrome clusters many of the IHD risk factors such as obesity, insulin resistance, dyslipidemia, glucose intolerance, hypertension, and inflammatory markers, and predicts IHD, results observed in atomic bomb survivors led us to hypothesize that visceral fat accumulation or metabolic syndrome may explain the association between atomic bomb radiation and IHD. Therefore, to examine this possibility, we used fatty liver, which is a surrogate marker of visceral fat accumulation or metabolic syndrome, and examined whether fatty liver: (1) clusters the IHD risk factors; (2) is related to radiation dose; and (3) predicts IHD in atomic bomb survivors. We defined that fatty liver: (1) is associated with obesity (P P P P P P P = 0.02); and (3) predicts IHD (P = 0.04). These results suggest that visceral fat accumulation or metabolic syndrome might be involved in the basic mechanism(s) explaining the association between atomic bomb radiation and IHD.

The regular periodontal practice of scaling and root planing producesa smear layer on the root surface that is detrimental to the readhesion oftissues during subsequent regeneration therapy. Although it has beendemonstrated that gels containing the chelating agentethylenediaminetetraacetic acid (EDTA) can assist in the removal of thiscontaminating layer, no quantitative method is yet available by which toevaluate the efficiency of the treatment. In this article, the power ofatomic force microscopy (AFM) as a technique for monitoring and mappingthe surfaces of dentinal roots is demonstrated. Roughness parameters ofteeth that had been scaled and root planed were determined from AFM imagesacquired both before and after treatment with EDTA. The results confirmedthat EDTA is an efficient cleaning agent and that dentinal samples freefrom a smear layer are significantly rougher than the same samples coveredby a contaminating layer. AFM analysis is superior to alternative methodsinvolving scanning electron microscopy because the same sample section canbe analyzed many times, thus permitting it to be used as both the controland the treatment surface. 041b061a72
