A search for the relic neutrinos from all past core-collapse supernovae was conducted using 1496 days of data from the Super-Kamiokande detector. This analysis looked for electron-type antineutrinos ...that had produced a positron with an energy greater than 18 MeV. In the absence of a signal, 90% C.L. upper limits on the total flux were set for several theoretical models; these limits ranged from 20 to 130 macro nu(e) cm(-2) s(-1). Additionally, an upper bound of 1.2 macro nu(e) cm(-2) s(-1) was set for the supernova relic neutrino flux in the energy region E(nu)>19.3 MeV.
Abstract Objectives The aim of this study was to assess the relationship between the pericardial fat volume (PFV) and the characteristics of coronary plaques in patients with ischemic heart disease ...(IHD). Background It has been suggested that pericardial adipose tissue promotes plaque development in coronary artery disease (CAD). Methods We analyzed the cardiac computed tomography scans in consecutive patients suspected of CAD. PFV was quantified using validated software and indexed to body surface area, and the severity of coronary stenosis was evaluated in the patients who underwent coronary angiography. A total of 105 subjects (mean age, 68 ± 10 years) with IHD were categorized into tertiles of body surface area-indexed PFV values (PFVi, cm3 /m2 ): low-tertile, PFVi < 81.2 cm3 /m2 ; mid-tertile, 81.2 cm3 /m2 ≤ PFVi ≤ 114 cm3 /m2 ; high-tertile, PFVi > 114 cm3 /m2 . Their body mass index (BMI), waist circumference, Gensini score (GS), and coronary plaque component were evaluated. Results The GS was significantly different between the high-tertile and the low-tertile groups, indicating a stepwise decrease in GS from high-tertile to mid-tertile and to low-tertile. PFVi had a significant positive correlation with BMI ( p = 0.0001) and GS ( p < 0.0001). However, no significant association was found between GS and BMI. On the multivariate analysis, high PFVi remained an independent predictor for the coronary artery disease severity ( p < 0.001), while BMI and waist circumference were not independent predictors. Conclusions Obese patients were found to have more PFVi, and the characteristics of their coronary lesions were more severe. Pericardial adipose tissue as unique ectopic fat might be more highly associated with IHD progression.

Aortic dissection is an infrequent but important cause of acute ischemic stroke (AIS), and must not be overlooked because of a possible worse outcome, especially with the use of an intravenous ...recombinant tissue plasminogen activator. We report a case of left carotid artery dissection and AIS originating from localized aortic arch dissection, pathologically caused by cystic medial necrosis in the tunica media.
