Abstract
BACKGROUND We aimed to compare clinical outcomes between immediate and staged complete revascularization in primary percutaneous coronary intervention (PCI) for treating ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD). METHODS A total of 248 patients were enrolled in a prospective, randomized, and multicenter registry. Immediate revascularization was defined as one-time PCI of culprit and non-culprit lesions at the initial procedure. Staged revascularization was defined as PCI of non-culprit lesions at a later date (mean, 4.4 days; interquartile range, 1-11.4), following initial culprit revascularization. The end points were major adverse cardiovascular events (MACE; composite of total death, recurrent myocardial infarction, and revascularization), any individual components of MACE, cardiac death, stent thrombosis, and stroke at 12 months. RESULTS During a follow-up of 1 year, MACE occurred in 12 patients (11.6%) in the immediate revascularization group and in 8 patients (7.5%) in staged revascularization group (hazard ratio [HR] 1.60, 95% confidence interval [CI] 0.65-3.91). The incidence of total death was numerically higher in the immediate group than in the staged group (9.7% vs 2.8%, HR 3.53, 95% CI 0.97-12.84); There were no significant differences between the 2 groups in risks of any individual component of MACE, cardiac death, stroke, and in-hospital complications, such as need for transfusion, bleeding, acute renal failure, and acute heart failure. This study was prematurely terminated due to halt of production of everolimus-eluting stents (manufactured as PROMUS Element by Boston Scientific, Natick, Massachusetts). CONCLUSIONS Due to its limited power, no definite conclusion can be drawn regarding complete revascularization strategy from the present study. Further large randomized clinical trials would be warranted to confirm optimal timing of complete revascularization for patients with STEMI and MVD.

Abstract
Chronic allograft nephropathy (CAN) includes pathologic changes of interstitial fibrosis, tubular atrophy, and fibrous intimal thickening. Transforming growth factor (TGF)-beta1 is a fibrogenic cytokine involved in renal allograft fibrosis. Hypoxia-inducible factor (HIF)-1alpha is induced as an adaptive response to hypoxia triggering the production of fibrogenic cytokines such as TGF-beta1. Between January 1995 and February 2005, we performed 71 renal allograft biopsies in 61 recipients. Immunohistochemical studies were performed with an immunoperoxidase technique using as the primary antibody either a rabbit anti-human TGF-beta1 polyclonal or a mouse anti-human HIF-1alpha monoclonal reagent. The glomerular TGF-beta1 expression in recipients diagnosed with glomerulonephritis was significantly greater than other pathologic groups (P < .05), and the glomerular TGF-beta1 expression in the heavy proteinuria group (> or =2.5 g/d) was significantly greater than the low proteinuria group (<1.0 g/d; P < .05). The tubular and interstitial TGF-beta1 and HIF-1alpha expressions in CAN were greater than in other groups (P < .05). The tubular TGF-beta1 expression among the graft loss group was significantly greater than the graft function group (P < .05).

Abstract
OBJECTIVE In dealing with cases of oedematous brain, relaxation during the transsylvian approach to supratentorial aneurysms has been accomplished by ventricular drainage by using the anatomic point defined by Dr. Paine. However, we have experienced patient complications when using this point. We propose a novel anatomic point to reduce catheter-related complications and facilitate adequate ventricular puncture during ruptured aneurysm operations. METHODS Ten patients underwent aneurysmal neck clipping for ruptured aneurysm by means of the transsylvian approach. The use of a novel anatomic point for intraoperative drainage was examined using a neuronavigation system. RESULTS Using the novel point of entry for ventricular cannulation proved to be reliable for puncture and reduced chance of malpositioning. CONCLUSION Secure intraoperative ventricular cannulation is reliably achieved by pointing the catheter approximately 2 cm beyond a line extending from the anterior limb of the triangle described by Paine. This technique reduces injury to the deep brain and enhances preciseness and safety of ventricular cannulation.

Abstract
We have monitored mitogen-stimulated mouse splenocyte proliferation as a biological end point of radiation damages to access adaptive response to ionizing radiation. When cells were pre-exposed to an adapting dose of 0. 01 Gy of low dose gamma-ray 4, 7, and 20 hours prior to an acute challenging dose of 2 Gy, most significant enhancement in splenocyte proliferation was induced at 4 hour interval. When the challenging high dose was varied, an adaptive response was observed at up to 4 Gy of high dose gamma-ray challenge. Gamma-ray-irradiated mouse splenocyte showed characteristic morphology of apoptotic cells. The extent of DNA fragmentation, another characteristic of apoptotic cells, was also reduced in low dose gamma-ray-adapted cells. The addition of protein or RNA synthesis inhibitor, cycloheximide or 5,6-dichloro-1-beta-d-ribofuranosylbenzimidazol (DRFB), respectively during adaptation period, the period between low and high dose irradiations, were able to inhibit the induction of adaptive response. These data suggest that to induce adaptive response to ionizing radiation in mouse splenocytes, both protein and RNA synthesis are required.
