Abstract
Experimental investigations of transactinoide elements provide benchmark results for chemical theory and probe the predictive power of trends in the periodic table. So far, in gas-phase chemical reactions, simple inorganic compounds with the transactinoide in its highest oxidation state have been synthesized. Single-atom production rates, short half-lives, and harsh experimental conditions limited the number of experimentally accessible compounds. We applied a gas-phase carbonylation technique previously tested on short-lived molybdenum (Mo) and tungsten (W) isotopes to the preparation of a carbonyl complex of seaborgium, the 106th element. The volatile seaborgium complex showed the same volatility and reactivity with a silicon dioxide surface as those of the hexacarbonyl complexes of the lighter homologs Mo and W. Comparison of the product's adsorption enthalpy with theoretical predictions and data for the lighter congeners supported a Sg(CO)6 formulation.

Abstract
Autoimmune neutropenia (AIN), resulting from granulocyte-specific autoantibodies, is much less frequent than other autoimmune hematologic disorders including autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). These autoimmune disorders may precede, synchronize, or follow collagen disorders, viral infections, and lymphoid neoplasms. Herein we present the first case of AIN in association with Helicobacter pylori-negative mucosa-associated lymphoid tissue (MALT) lymphoma with nodal dissemination. In our case, AIN, accompanied by ITP, occurred prior to the clinical manifestation of lymphoma. AIN and ITP were well managed afterwards, but they relapsed in accordance with the recurrence of lymphoma. The administration of prednisolone at 0.5 mg/kg daily alleviated the cytopenias within a week. In general, combination chemotherapy is performed for the treatment of lymphoma-associated autoimmune hematologic disorders and indeed seems to be effective. Our case indicates that corticosteroid monotherapy may be effective for lymphoma-associated AIN especially when AIN precedes the onset of lymphoma.

Abstract
OBJECTIVES We conducted an acute experimental study to test the feasibility of dynamic cardiomyoplasty in a setting of modified Fontan procedure for univentricular heart with pulmonary hypertension to obtain a possible proxy for high-risk Fontan candidates. METHODS After electrical preconditioning of the left latissimuss dorsi for 6 weeks in 8 dogs, the right ventricular cavity was totally obliterated with concomittent closure of the tricuspid valve and right pulmonary artery. Modified Fontan circulation was established with the aortic homograft anastomosed between the right atrium and pulmonary trunk, incorporated with a pericardial pouch as a compression chamber (neoright ventricle) fixed onto the epicardial surface of the ventricle. After cardiopulmonary bypass termination, a latissimus dorsi was applied to wrap the pericardial pouch and ventricle clockwise and stimulated with a trained-pulse (25 Hz) at 1:1 synchronization ratio with cardiac beats. RESULTS Profound right heart failure was noted during Fontan circulation in increased pulmonary vascular resistance (11 +/- 3.2 Wood units), whereas graft pacing showed significant augmentation of systolic pulmonary pressure by 54 +/- 12%, the mean pulmonary flow by 68 +/- 23%, and aortic pressure by 23 +/- 5% at a physiological range of central venous pressure (13.2 +/- 0.7 mmHg). Right heart function curve analysis confirmed marked augmentation of right heart performance, restoring almost normal pulmonary circulation. These functional benefits were sustained up to 4 hours in 4 animals until experiments were terminated. CONCLUSIONS Dynamic cardiomyoplasty in a modified Fontan procedure is a viable surgical option for univentricular heart, not a Fontan candidate.

Abstract
Waldenström macroglobulinemia is a lymphoplasmacytic lymphoma characterized by production of the immunoglobulin M (IgM) monoclonal protein. Commonly involved sites are the bone marrow, lymph nodes, and spleen. Lymphoplasmacytic infiltration of the central nervous system (CNS), in contrast, is referred to as Bing-Neel syndrome, and is an extremely rare phenomenon. Here, we present a unique case of Waldenström macroglobulinemia with optic neuritis accompanied by monoclonal expansion of T cells, which recovered after administration of CNS-targeting chemotherapy. Although the underlying causal relationships in this case remain obscure, aberrantly expanded T cells may have contributed to the development of optic neuritis, and we should be reminded that some types of cranial neuropathy in Waldenström macroglobulinemia may be reversible.

Abstract
Rats were subjected to 90min of focal ischemia by occluding the left middle cerebral and both common carotid arteries. The dynamic changes in the formation of brain ischemic areas were analyzed by measuring the direct current (DC) potential and reduced nicotinamide adenine dinucleotide (NADH) fluorescence with ultraviolet irradiation. In the lidocaine group (n=10), 30min before ischemia, an intravenous bolus (1.5mg/kg) of lidocaine was administered, followed by a continuous infusion (2mg/kg/h) for 150min. In the control group (n=10), an equivalent amount of saline was administered. Following the initiation of ischemia, an area of high-intensity NADH fluorescence rapidly developed in the middle cerebral artery territory in both groups and the DC potential in this area showed ischemic depolarization. An increase in NADH fluorescence closely correlated with the DC depolarization. The blood flow in the marginal zone of both groups showed a similar decrease. Five minutes after the onset of ischemia, the area of high-intensity NADH fluorescence was significantly smaller in the lidocaine group (67% of the control; P=0.01). This was likely due to the suppression of ischemic depolarization by blockage of voltage-dependent sodium channels with lidocaine. Although lidocaine administration did not attenuate the number of peri-infarct depolarizations during ischemia, the high-intensity area and infarct volume were significantly smaller in the lidocaine group both at the end of ischemia (78% of the control; P=0.046) and 24h later (P=0.02). A logistic regression analysis demonstrated a relationship between the duration of ischemic depolarization and histologic damage and revealed that lidocaine administration did not attenuate neuronal damage when the duration of depolarization was identical. These findings indicate that the mechanism by which lidocaine decreases infarct volume is primarily through a reduction of the brain area undergoing NADH fluorescence increases which closely correlates with depolarization.

Abstract
BACKGROUND Spontaneous rupture risk of a renal artery aneurysm (RAA) is extremely low. Indications for surgical repair of RAA remain uncertain. OBJECTIVE Long-term outcomes of conservative therapy and surgical repair were evaluated. PATIENTS The study included 58 patients (17 males, 41 females) who were diagnosed with RAA during the last 21 years. Median age at the time of diagnosis was 62 (19-85) years, and the median follow-up 69 months (range 3-216). METHODS The patients were divided into two groups, conservative group (n = 30) who had been followed with blood pressure control, and treatment group (n = 29), who underwent an intervention. RESULTS Multiple efferent aneurysmal branches were observed in seven conservative and 16 treatment cases (P = .002). The median maximum diameter of the aneurysm was lower in the conservative than the treatment group (15 versus 25 mm, P = .005). Two conservative group cases showed increases in aneurysm size during follow-up. The hypertensive state showed essentially no change in either group during the follow-up. Renal function decreased with age similarly both in conservative and treatment groups. CONCLUSIONS Our conservative management criteria for RAA are justifiable and even too strict.

Abstract
Early intervention for psychosis in Japan has lagged behind that in western countries, but has rapidly begun to attract attention in recent years. As part of a worldwide trend, a multi-dimensional treatment centre for early psychosis consisting of a Youth Clinic, which specialises in young individuals with an at-risk mental state for psychosis, and Il Bosco, a special day-care service for individuals with early psychosis, was initiated at the Toho University Omori Medical Center in Japan in 2007. The treatment centre aims to provide early intervention to prevent the development of full-blown psychosis in patients with an at-risk mental state and intensive rehabilitation to enable first-episode schizophrenia patients to return to the community. We presently provide the same programmes for both groups at Il Bosco. However, different approaches may need to be considered for patients with an at-risk mental state and for those with first-episode schizophrenia. More phase-specific and need-specific services will be indispensable for early psychiatric interventions in the future.

Abstract
PURPOSE Successful kidney transplantation (KTx) can ameliorate bodily damage caused by end-stage renal disease (ESRD). Arterial stiffness (AS) is one of the critical factors that shorten the survival of patients due to cardiovascular events. KTx may reduce AS as well; however, this has not been investigated well. We therefore conducted a retrospective study using noninvasive pulse wave velocity (PWV), which is a useful index of aortic damage. PATIENTS AND METHODS Fifty-eight consecutive kidney recipients (34 men, 24 women) were enrolled in this study. Mean age at transplantation was 40.5 ± 12.3 years and the dialysis period was 73.1 ± 95.8 months. The brachial-ankle PWV was measured preoperatively and 6 months postoperatively. First, we investigated the relationship between the PWV and the other parameters related to AS. Second, we studied the pre- to posttransplant change in PWV to evaluate the amelioration of AS after successful KTx. RESULTS PWV showed significant positive correlations with age, systolic blood pressure (BP), diastolic BP, and abdominal aortic calcification index. After successful KTx, PWV significantly decreased (P < .01). In addition, systolic and diastolic BP significantly decreased (P < .01 and P < .05, respectively). CONCLUSION Successful KTx ameliorates AS in ESRD patients. This might explain the improved cardiovascular prognosis of ESRD patients who undergo KTx.

Abstract
Human T cell leukemia virus type 1 (HTLV-1) is an endemic retrovirus in southwestern Japan, which causes adult T cell leukemia (ATL) or HTLV-1 associated myelopathy in a minority of carriers. Here, we investigated the impact of HTLV-1 status in living donor liver transplantation (LDLT). Twenty-six of 329 (7.9%) HTLV-1 carriers underwent primary LDLT. One recipient negative for HTLV-1 before LDLT received a graft from an HTLV-1 positive donor. Eight donors were HTLV-1 positive. Twenty-seven recipients (13 male and 14 female; mean age 52.5 years) were reviewed retrospectively. ATL developed in four recipients who ultimately died. The intervals between LDLT and ATL development ranged from 181 to 1315 days. Of the four ATL recipients, two received grafts from HTLV-1 positive donors and two from negative donors. The 1-, 3- and 5-year HTLV-1 carrier survival rates were 91.3%, 78.3% and 66.3%, respectively. Fulminant hepatic failure as a pretransplant diagnosis and a pretransplant MELD score ≥ 15 was identified as risk factors for ATL development in this study (p = 0.001 and p = 0.041, respectively). In conclusion, LDLT can be performed for HTLV-1 positive recipients. However, when fulminant hepatic failure is diagnosed, LDLT should not be performed until further studies have revealed the mechanisms of ATL development.

BACKGROUND AND PURPOSE Although 3D FLAIR imaging visualizes detailed structures of the brain stem, it has not been used to evaluate its normal anatomy. The purpose of this study was to evaluate whether 3D FLAIR images can provide more detailed anatomic information of the brain stem than 2D FLAIR and 2D T2WI. MATERIALS AND METHODS We prospectively evaluated MR images in 10 healthy volunteers. 3D and 2D FLAIR images, 2D T2WI, and DTI were obtained on a 3T MR imaging scanner. A VISTA technique was used for 3D FLAIR imaging. White matter tracts and nuclei of the brain stem were determined on 3D and 2D FLAIR images and 2D T2WI by referring to anatomic atlases and DTI color maps. The subjective assessment of the visibility by using a 4-point grading system and the contrast ratio of the structures on 3D and 2D FLAIR images and 2D T2WI were evaluated. RESULTS The visibility of the SCP and MCP, DSCP, CST, and CTT was higher on 3D FLAIR images than on 2D T2WI and 2D FLAIR images. The contrast ratio for the CST, SCP, MCP, DSCP, and CTT was significantly different on 3D FLAIR images and 2D T2WI and on 3D FLAIR and 2D FLAIR images; there was no significant difference in contrast ratio for the SCP at the pons on 3D FLAIR and 2D T2WI. CONCLUSIONS 3D FLAIR images provide detailed anatomic information of the brain stem that cannot be obtained on 2D T2WI and 2D FLAIR images.
