OBJECTIVE The internal thoracic artery (ITA) is the most important graft in coronary artery bypass grafting. Its distal region is, however, prone to vasospasm. We studied the effects of nitroglycerin (NTG) and isosorbide-dinitrate (DSDN) on distal segments of left versus right ITA. METHODS Rings of distal segments (6 to 9 mm proximal to bifurcation) of the human left and right ITA were studie...

Since December 2009, after breast-conserving surgery for Stage 0-I cancer of the left breast, 21 women with relatively pendulous breasts underwent computed tomography prone and supine simulations. The adjuvant radiotherapy was 50 Gy in 25 fractions to the left breast alone. Four plans--conventional wedged tangents and forward intensity-modulated radiotherapy (fIMRT) in supine and prone position...

To explore the influence of health psychology characteristics bus driver on probability traffic accidents, such as severity unhealthy and negative impulsive personality. Combined with demographic questionnaire, SCL-90 scale, Y-G psychological factors drivers causing accidents were evaluated. The key selected by binary logistic regression analysis are used node variables, Bayesian network struct...

OBJECTIVE The left internal thoracic artery (LITA) is the most important graft for coronary artery bypass grafting (CABG). Its distal region is, however, prone to vasospasm. The effect of nitroglycerin (NTG) and isosorbide-dinitrate (ISDN) on different segments of this region was studied. METHODS Rings of three segments of the LITA were studied: 6-9 mm proximal to the bifurcation (part A); 1-...

The history of research into individual liability to accidents is long and troubled (Iverson and Erwin1997). Some researchers studied the distribution and risk of accidents, and concluded that various groups of individuals displayed differences in susceptibility to accidents (Peters1989; Bhattacherjee1991). Other investigators sought to characterize the accident-prone individuals either by comp...

Safety analysis according to the spatial distribution characteristics of maritime traffic accidents is critical safety management. An accident framework based on geographic information system (GIS) proposed characterize occurring in Fujian sea area 2007–2020 by employing kernel density estimation and autocorrelation techniques. The divided into various grids, each grid, mapping relationships be...
