Abstract
BACKGROUND Various malignant tumors of the body show high signal intensity on diffusion-weighted magnetic resonance imaging (DWI). In the genitourinary region, DWI is expected to have a role in detecting urinary epithelial cancer noninvasively. PURPOSE To demonstrate the feasibility of DWI for the diagnosis of urinary epithelial cancer with upper urinary tract obstruction. MATERIAL AND METHODS Twenty upper urinary tract cancers in 16 patients were evaluated by high-b-value DWI (b=800 s/mm(2)). The signal intensity was visually evaluated, and the apparent diffusion coefficients (ADCs) were measured. RESULTS All urinary epithelial cancers showed high signal intensity on DWI. The ADC in cancerous lesions was 1.31+/-0.27 x 10(-3) mm(2)/s, which was significantly lower than that of the lumens of the ureter or renal pelvis (3.32+/-0.44 x 10(-3) mm(2)/s; P<0.001). Maximum intensity projection images of DWI in combination with static-fluid MR urography provided three-dimensional entire urinary tract imaging with the extension of tumors. CONCLUSION DWI is useful in the tumor detection and in evaluating the tumor extension of urinary epithelial cancer in patients with upper urinary tract obstruction.

Abstract
This study investigated the differences in apnoea-hypopnoea index (AHI) during rapid eye movement (REM) sleep (AHI-REM) and AHI during non-REM (NREM) sleep (AHI-NREM) in patients with obstructive sleep apnoea (OSA). Nocturnal polysomnography was performed in 102 Japanese OSA patients and their AHI along with a variety of other factors were retrospectively evaluated. Regardless of the severity of AHI, mean apnoea duration was longer and patients' lowest recorded oxygen saturation measured by pulse oximetry was lower during REM sleep than during NREM sleep. Approximately half of the patients ( n = 50) had a higher AHI-NREM than AHI-REM. In subjects with AHI ≤ 60 events/h, AHI-NREM was significantly higher than AHI-REM. On multivariate logistic regression, severe AHI ≤ 30 events/h was the only predictor of a higher AHI-NREM than AHI-REM. This may indicate that important, but unknown, factors related to the mechanism responsible for the severity of OSA are operative during NREM sleep.

Abstract
The authors report a case of a combined endovascular and open repair (hybrid procedure) for a mycotic thoracoabdominal aneurysm (TAAA) including its 6-year result. A 72-year-old man with diabetes mellitus, old brain infarction and moderate aortic stenosis was transferred to the hospital because of obstinate fever and back pain, The initial computed tomography (CT) scan revealed giant (TAAA), and from the laboratory findings, the white blood cell and C-reactive protein (CRP) were significantly elevated 12,400/mm3 and 23.9 mg/dL respectively. Based on the CT and laboratory findings, a mycotic TAAA was highly suspected. After the remission of inflammation, graft replacement with reconstruction of celiac trunk (CA) and superior mesenteric artery (SMA) was performed via spiral incision under extracorporeal circulation. two months after the first operation, the patient complained about his back pain again. CT showed a pseudoaneurysm which formed at the distal anastomotic site. A hybrid procedure was deemed to be the most appropriate for such patient who needs a second operation. First bilateral renal artery bypass (ilio-renal artery bypass) were done using the saphenous vein grafts (SVGs). Following bypass grafting to renal arteries, endovascular aneurysm repair was performed with handmade stent-graft which was fabricated using a self-expanding "Z" stent and woven Dacron graft. The postoperative course was uneventful, and follow-up CT showed the aneurysm to have shrunk with no endoleaks. At six months after hybrid procedure, the shrinkage of the aneurysm sac and the patency of the graft to renal arteries were confirmed by a CT scan. A hybrid procedure is considered to be useful and feasible for the poor surgical candidate with severe comorbidities, hostile abdomen and a complex anatomy. The long-term results of this hybrid procedure is considered to be promising.

Abstract
BACKGROUND Mass-forming chronic pancreatitis may mimic a pancreatic cancer on dynamic computed tomography (CT) and magnetic resonance (MR) imaging, and preoperative differential diagnosis is often difficult. Recently, the usefulness of diffusion-weighted MR imaging (DWI) in the diagnosis of pancreatic cancer has been reported in several studies. PURPOSE To determine whether high-b-value DWI can distinguish pancreatic cancer from benign mass-forming chronic pancreatitis. MATERIAL AND METHODS Twenty pancreatic cancers and four cases of mass-forming chronic pancreatitis were evaluated by high-b-value DWI (b=800 s/mm(2)). The signal intensity on DWI was visually evaluated, and the isotropic apparent diffusion coefficients (ADCs) were measured. RESULTS All twenty pancreatic cancers showed high signal intensity (18 showed very high, two showed slightly high) on DWI. None of the mass-forming chronic pancreatitis cases showed very high intensity (three showed iso to low, one showed slightly high) on DWI. The ADCs in the pancreatic cancer and mass-forming chronic pancreatitis were 1.38 +/- 0.32 x 10(-3) mm(2)/s and 1.00 +/- 0.18 x 10(-3) mm(2)/s, respectively (P < 0.05). CONCLUSION On high-b-value DWI, most pancreatic cancers showed very high signal intensity, and may hence be distinguished from benign mass-forming chronic pancreatitis based on our preliminary results.

Abstract
A 65-year-old man underwent a prosthetic graft replacement for a rupture of the saccular descending thoracic aneurysm in the lung. Chest computed tomography (CT) performed on the day of admission was suggestive of a thrombosed localized aortic dissection. However, sagittal plane CT performed on the following day indicated the rupture of a penetrating atherosclerotic ulcer. The operation was performed approximately 36h after the onset of the symptom since diagnosis was difficult due to the following reasons. First, the size of the saccular aortic aneurysm was not sufficiently large, i.e., it was 4.5 cm diameter and 3.0 cm in length. Second, the aneurysm was completely filled with thrombus: therefore, it could not be enhanced on CT scanning. Third, since the aneurysm was present on the side of the greater curvature of the descending aorta, the protrusion of the aneurysm was very indistinct. Fourth, the amount of bleeding was not significant because the rupture was extremely small, approximately 2 mm in width. Fifth, only an interlobar hematoma was observed due to the tight adhesion of the lung with the aorta.

Abstract
We report a case of emergent coronary artery bypass grafting (CABG) in a survivor of an out-of-hospital cardiac arrest. A 64-year-old male driver lost consciousness and collapsed in a rice paddy field. A bystander placed him in a car and immediately started cardiopulmonary resuscitation after confirming the presence of pulselessness and apnea. Emergency medical service providers performed a defibrillation of ventricular fibrillation by using an automated external defibrillator (AED), and the patient was transferred to the critical care center in our hospital. Coronary angiography revealed a thrombus in the left main trunk (LMT), total occlusion of the left anterior descending artery (LAD) and the right coronary artery (RCA), and 90% stenosis of the left circumflex artery (Cx). Since the patient recovered consciousness 1 hour after admission and did not undergo any critical trauma, an on-pump CABG was performed for 3 vessels. He was discharged on the postoperative day 23, and he resumed a normal life.

Abstract
139La- and 55Mn-NMR spectra demonstrate that the ground state of the A-site-ordered perovskite manganite LaBaMn2O6 is a spatial mixture of the ferromagnetic and antiferromagnetic regions, which are assigned to the metallic and the insulating charge ordered state, respectively. This exotic coexisting state appears below 200 K via a first-order-like formation of the antiferromagnetic charge ordered state inside the ferromagnetic metal one. The Mn spin-spin relaxation rate indicates that the ferromagnetic region coexisting with the antiferromagnetic one in LaBaMn2O6 is identical to the bulk ferromagnetic metal phase of the disordered form La0.5Ba0.5MnO3 in spite of the absence of A-site disorder. This suggests a mesoscopic rather than nanoscopic nature of the ferromagnetic region in LaBaMn2O6.

Abstract
In the present work we report cross sections for electron collisions with the isomers propene (C3H6) and cyclopropane (c-C3H6). Electron-scattering differential cross sections (DCS) are reported for measurements carried out for energies 1.5-100 eV and the angular range of 20 degrees-120 degrees. Elastic integral cross sections (ECS), DCS, and momentum-transfer cross sections (MTCS) are reported for calculations carried out using the Schwinger multichannel method with pseudopotentials for the energy range of 2.0-40 eV and angular range of 0 degrees-180 degrees. The resemblance of the pi* shape resonance in the cross sections, observed at 1.5-2.0 eV for propene, to those in C2H4 and C2F4 clearly points to the effect of the double bond in the molecular structures for these molecules. Below 60 eV, we observed clear differences in peak positions and magnitudes between the DCS, ECS, and MTCS for C3H6 and c-C3H6, which we view as the isomer effect.

Abstract
BACKGROUND Although liver transplantation has become a standard therapy for diseases such as fulminant hepatitis and cirrhosis, the lack of donor organs remains a major problem. One solution is the development of transplantable hepatocytes. The metabolic characteristics as well as function and adaptation of hepatocytes (R-EES-hep cell) derived from rat early embryonic stem cells were examined after transplantation into rats with surgically induced liver failure. METHODS Rat hepatocyte cell lines were established from early embryonic stem cells cultured in the presence of embryotrophic factors by colony cloning methods. The cell lines were established from two cell embryos taken from spontaneous dwarf rats using the novel method of Ishiwata et al. Morphologic differentiation as well as albumin and bilirubin production were observed by immunostaining. R-EES-hep cells were transplanted into the spleens of 90% hepatectomized, surgically induced liver failure rats to analyze survival rates. RESULTS When cultured in type I collagen gel the cells formed cordlike structures resembling the liver. Both albumin and bilirubin production were observed when transplanted; the spleen was converted into a liver-like structure with prolonged survival of the 90% hepatectomized rats for up to 3 months up to the time of killing. CONCLUSIONS R-EES-hep cells showed many of the distinctive metabolic characteristics of the liver. These cells may be efficient for further research and application for hepatic cell transplantation to treat liver insufficiency patients and as biologic artificial organs.

Abstract
BACKGROUND Tissue repair often occurs in organs damaged by various inflammatory diseases including pneumonia. Inflammatory stimuli induce a rapid and massive release of inflammatory cells from the bone marrow. Recent studies have suggested that bone marrow cells have the potential to differentiate into a variety of cell types. It has been shown that administration of lipopolysaccharide (LPS) to murine lungs induces a rapid release of endothelial progenitor cells (EPCs) into the circulation, and that bone marrow derived progenitor cells including EPCs contribute to lung repair after lung injury in mice. This study was undertaken to investigate the mobilisation of EPCs in humans following acute pneumonia. METHODS Peripheral blood mononuclear cells (PBMCs) were isolated from venous blood taken from 23 patients with pneumonia during both the acute and convalescent phase. 1x10(6) PBMCs were plated on fibronectin coated culture slides and cultured in culture medium for endothelium. The numbers of EPCs were counted 8 days after plating. RESULTS The number of circulating EPCs significantly increased in patients with pneumonia (p<0.0001). Patients with low EPC counts tended to have persistent fibrotic changes in their lungs even after their recovery from pneumonia. CONCLUSIONS Inflammatory stimuli induce a rapid release of EPCs into the circulation in humans. A sufficient number of EPCs is necessary for proper lung repair following bacterial pneumonia.

Abstract
We report on two Japanese brothers with hereditary deficiency in gamma-glutamyl transpeptidase. The propositus was 48 years old when he first visited our medical center and had a 51-year-old brother. The brothers were both tall and slender and had long limbs; the younger was diagnosed as having Marfan syndrome. Both patients both showed a tendency to retarded mental development. gamma-Glutamyltranspeptidase activity was below the detection limit of 1 IU/L in both patients. Glutathionaemia and glutathionuria were evident in both brothers. The analyses of sulphydryl compounds in the plasma (and serum for certain test items) and urine indicated high concentrations of glutathione, gamma-glutamylcysteine, cysteine and cysteinylglycine. Urine amino acid analysis on an automatic analyser showed a slightly increased excretion of cystine and a large peak in the citrulline position due, at least in part, to thio-compounds.
