Abstract
We present results of specific heat measurements on a Ce3Pd20Si6 single crystal and construct the magnetic phase diagram for the three cubic principal directions [100], [110] and [111]. The highly anisotropic phase diagram is discussed and can be qualitatively explained by the Zeeman splitting at the 8c-site. For B ‖ [100], the present study found two different quadrupolar ordered phases, which meet the paramagnetic phase at a tri-critical point and establish the new phase boundaries.

Abstract
BACKGROUND AND PURPOSE The analgesic action of 5-HT and noradrenaline reuptake inhibitors (SNRIs) on nociceptive synaptic transmission in the spinal cord is poorly understood. We investigated the effects of milnacipran, an SNRI, on C-fibre-evoked field potentials (FPs) in spinal long-term potentiation (LTP), a proposed synaptic mechanism of hypersensitivity, and on the FPs in a neuropathic pain model. EXPERIMENTAL APPROACH C-fibre-evoked FPs by electrical stimulation of the sciatic nerve fibres were recorded in the spinal dorsal horn of anaesthetized adult rats, and LTP was induced by high-frequency stimulation of the sciatic nerve fibres. A rat model of neuropathic pain was produced by L5 spinal nerve ligation and transection. KEY RESULTS Milnacipran produced prolonged inhibition of C-fibre-evoked FPs when applied spinally after the establishment of LTP of C-fibre-evoked FPs in naïve animals. In the neuropathic pain model, spinal administration of milnacipran clearly reduced the basal C-fibre-evoked FPs. These inhibitory effects of milnacipran were blocked by spinal administration of methysergide, a 5-HT½ receptor antagonist, and yohimbine or idazoxan, α₂-adrenoceptor antagonists. However, spinal administration of milnacipran in naïve animals did not affect the basal C-fibre-evoked FPs and the induction of spinal LTP. CONCLUSION AND IMPLICATIONS Milnacipran inhibited C-fibre-mediated nociceptive synaptic transmission in the spinal dorsal horn after the establishment of spinal LTP and in the neuropathic pain model, by activating both spinal 5-hydroxytryptaminergic and noradrenergic systems. The condition-dependent inhibition of the C-fibre-mediated transmission by milnacipran could provide novel evidence regarding the analgesic mechanisms of SNRIs in chronic pain.

Abstract
Synthetic 4-methylsulfinylhexyl isothiocyanate (MITC)(a potent inducer of phase 2 detoxification enzymes from broccoli) and 6-MITC(a potent anti-proliferative principal from wasabi) slightly inhibited the induction of mouse skin tumor in a two-stage process of carcinogenesis (initiator, 9,10-dimethyl-1,2-benzanthracene; promotor,12-o-tetradecanoylphorbol-13-acetate), but the effect was not significant. Both compounds, however, significantly inhibited the mutation of skin resulting from topical applications of the carcinogens. When a murine hepatoma cell line, Hepa 1c1c7, was treated with 2-,4-,6- and 8-MITCs, they augmented the induction of its quinone reductase, one of the phase 2 detoxification enzymes in a concentration dependent manner, and the 4- and 6-MITCs were much more potent on the reduction of the enzyme than the 2- and 8-MITCs. All 2-, 4-, 6- and 8-MITCs suppressed the growth of murine tumor cells, their suppressive activities being proportional to the length of their methyl residue. They were also cytotoxic to mouse peritoneal exudate macrophages which were not proliferating in vitro, indicating that the cellular targets of isothiocyanate may not be dependent upon the cell cycle. In addition, all the 2-, 4-, 6- and 8-MITCs inhibited the production of nitric oxide (a potent radical carcinogen) by peritoneal macrophages.

Abstract
BACKGROUND AND STUDY AIMS Little information exists regarding the optimal treatment of early gastric cancer (EGC) in a remnant stomach or gastric tube. The aim of this study was to assess the feasibility and clinical outcomes of endoscopic submucosal dissection (ESD) for EGC in a remnant stomach and gastric tube. PATIENTS AND METHODS Between September 2002 and December 2009, ESD was performed in 62 lesions in 59 patients with EGC in a remnant stomach (48 lesions) or gastric tube (14 lesions). Clinicopathological data were retrieved retrospectively to assess the en bloc resection rate, complications, and outcomes. Treatment results were assessed according to the indications for endoscopic resection, and were compared with those of ESD performed in a whole stomach during the same study period. RESULTS The en bloc resection rates for lesions within the standard and expanded indication were 100 % and 93 %, respectively. Postoperative bleeding occurred in five patients (8 %). The perforation rate was significantly higher (18 %, 11 /62) than that of ESD in a whole stomach (5 %, 69 /1479). Among the perforation cases, eight lesions involved the anastomotic site or stump line, and ulcerative changes were observed in five lesions. The 3-year overall survival rate was 85 %, with eight deaths due to other causes and no deaths from gastric cancer. CONCLUSION A high en bloc resection rate was achieved by ESD for EGC in a remnant stomach or gastric tube; however, this procedure is still technically demanding due to the high complication rate of perforation.

Abstract
Purpose. Histogenesis of synovial sarcoma remains controversial and reliable molecular markers for diagnosis are necessary. Expression of basic calponin, a smooth muscle differentiation-specific actin-binding protein, was studied in synovial sarcoma.Subjects and Methods. The basic calponin gene and the gene product were analyzed by reverse transcription PCR analysis (RT-PCR) and immunohistochemistry in 14 synovial sarcomas and a human synovial sarcoma cell line (HS-SY-II).Results and Discussion. Immunoreactivity for basic calponin was detected in the cytoplasm of 6 synovial sarcomas (43% positive). In the basic calponin-positive tumors and the HS-SY-II cells, expression for smooth muscle-specific genes, including basic calponin and SM22alpha , was detected by RT-PCR, suggesting a lineage relationship between synovial sarcoma cells and smooth muscle-like mesenchymal cells.Conclusions. A subset of synovial sarcomas expressing the basic calponin gene and the gene product were identified. The basic calponin may have potential utility as a novel molecular marker identifying certain synovial sarcomas.

Abstract
The relationship between human diseases caused by infection with Shiga toxin (Stx)-producing Escherichia coli (STEC) O157 strains and O157 strains isolated from cattle was investigated in an area where stockbreeding is prolific. For this purpose, the stx genotypes, the molecular epidemiological characteristics of 268 STEC O157 strains including 211 human-origin strains and 57 cattle-origin strains, and clinical manifestations of 210 STEC-infected people were analyzed. Of 211 human-origin strains, 92 strains (44%) were of the stx1/stx2 genotype, and 74 strains (35%) were of the stx2c genotype. Most of the people infected with stx2c genotype strains presented no symptoms or mild symptoms such as slight diarrhea, except for 3 patients with bloody diarrhea. Of the 57 cattle-origin strains, 27 strains (47%) were of the stx2c genotype and 17 strains (30%) were of the stx1/stx2 genotype. Pulsed-field gel electrophoresis (PFGE) and insertion sequence (IS) analysis demonstrated that 11 isolates (41%) of the 27 cattle isolates of the stx2c genotype had high homology (>95% identity) with human isolates. These results suggest that some genetic patterns of the stx2c genotype strains might be preserved in cattle or their surrounding environment for several years, and during these periods, they might have opportunities to infect people through various routes. Because of the mild virulence of the stx2c genotype strains, they seemed to be transmitted asymptomatically from cattle to humans and then spread from person to person. It may be a public health concern. Further, they occasionally cause severe symptoms in humans; therefore, caution is warranted for infections by stx2c genotype O157 strains, in addition to stx2-possessing genotype O157 strains.

Abstract
It has been reported previously that artificial gastric ulcers caused by endoscopic submucosal dissection (ESD) would heal within 8 weeks, irrespective of their size and location. The aim of this retrospective study was to describe long-term outcomes of gastric ESD ulcers. Check-up of ulcers was performed by periodic endoscopy. The rate of ESD ulcer recurrence and clinicopathological factors that may relate to recurrence were assessed. During the median observation period of 33 months, a benign ulcer recurrence occurred in 10 lesions in 10 patients (2.1%). Univariate analysis showed that Helicobacter pylori infection and presence of pathological ulcer findings within the ESD specimen were significantly related to the risk of ESD ulcer recurrence. Although the frequency is low, there is a possibility of ESD ulcer recurrence in patients with H. pylori infection and in patients who undergo ESD for a lesion with ulceration.

Abstract
ABSTRACTThe oxygen-containing silicon (Si) ultrafine particles have been deposited onto Si and SiO2 substrates by evaporation of Si powder in an oxygen-containing argon atmosphere. The asdeposited Si ultrafine particles exposed to the ultraviolet light emit blue light, which is strong enough to be seen with the naked eye. The blue light emission is associated with a broad photoluminescence (PL) peak at 2.7 eV, which is attributed to radiative recombination via a radiative recombination center. The proposed model with one radiative and two nonradiative recombination centers well explains the temperature-dependent PL peak intensity.

Abstract
Most previous studies have examined the effects of antihypertensive drugs in hypertensive animals for only a few months, and little information has been provided as to the protective effects of lifetime antihypertensive medication against cardiovascular organ injury. In this study, spontaneously hypertensive rats (SHR) were treated for 1 year with an angiotensin-II receptor antagonist (ARB) and the development of hypertensive organ injury was evaluated. Male 15-week-old SHR (n = 9) were given 25 mg/L candesartan (CS) in their drinking water for 1 year. Twelve SHR and 9 normotensive Wistar-Kyoto rats (WKY) were given normal tap water. Tail-cuff blood pressure was almost normalized by CS throughout 1 year (at 12-months: WKY 132 ± 3, SHR 229 ± 3, CS 137 ± 4 mmHg). After 1 year, cardiac ventricular weight (SHR +33%, CS -2% versus WKY) and aortic thickness (SHR +34%, CS +4% versus WKY) in the CS-treated SHR rats were not different than those of WKY. Echocardiographic midwall fractional shortening (SHR -18%, CS -1% versus WKY) and left ventricular hydroxyproline content (SHR +47%, CS +11% versus WKY) were also improved by CS to the WKY level. With respect to kidney function, GFR (SHR -24%, CS +9% versus WKY) was preserved, proteinuria (SHR +312%, CS +12% versus WKY) was reduced, and the histological glomerular injury rate (SHR +186%, CS +6% versus WKY) was reduced by CS. These results suggest that long-term antihypertensive therapy with CS can completely prevent hypertensive cardiovascular and renal injuries in SHR.

Abstract
Peristomal infection is a common complication following percutaneous endoscopic gastrostomy (PEG) placement. This study investigated the effect of gastric acidity on peristomal infection, including type of bacteria and the relationship between bacteria cultured from the oropharynx and PEG tube site. Sixty-seven patients with dysphagia underwent PEG placement at Otaki Hospital between 1998 and 2001. Gastric acidity was evaluated by 24h pH monitoring. Patients were observed for peristomal infection for two weeks after PEG placement, with specimens collected from the oropharynx and PEG tube site. Twenty-one (31.3%) of the patients who had undergone PEG insertion developed peristomal infections. Of 52 patients who were not colonised with meticillin-resistant Staphylococcus aureus (MRSA) in the oropharynx, 11 cases (21.2%) developed peristomal infection. The median gastric pH of infected patients (11 cases) was 5.05+/-2.55 (mean+/-SD) and in patients without infection (41 cases) it was 3.06+/-1.83 (P=0.019). Peristomal infection developed in 66.7% (10/15) of patients carrying MRSA compared with only 21.2% (11/52) of patients who were not colonised by MRSA (P<0.001). The incidence of peristomal infection was affected by gastric acidity and the presence of MRSA in the oropharynx.

Abstract
Low back pain and subsequent disabilities are common. A lumbar spinal fusion procedure is an effective treatment with autologous bone grafts, but harvesting the bone from the iliac crest is associated with risks of complications. New treatments using stem cells together with osteoconductive and otesoinductive materials have made the procedure safer, but the inconsistency of the amount of stem cells harvested from bone marrow aspirate still remains to be solved. This study reports that the bone dusts, usually discarded as surgical wastes during transforaminal lumbar interbody fusion procedure (TLIF procedure), yielded cells which had the characteristics of mesenchymal stem cells (MSCs) in vitro. The cells were positive for the MSC markers and were able to differentiate in osteogenic and adipogenic directions. The cells grew robustly in an osteoconductive material, Bolheal (serum glue), and also proliferated well in culture medium supplemented with autologous serum. Therefore, the bone dust is a good candidate for the alternative source of stem cells other than bone marrow aspirate to increase the safety of the TLIF procedure.

Abstract
We present here two cases wherein we performed radiolunate fusion using vascularized radius graft with the vascular pedicle of the fourth extensor compartment artery (fourth ECA) for the treatment of Bain's grade 2A Kienböck disease with incongruity of the radiolunate joint. The dorsodistal radius graft was levered out and mobilized on the pedicle of the fourth ECA; then the vascularized dorsodistal radius was shifted 1 cm distally and bridges were created between the radius and the lunate. The radiolunate joint was completely fused in both cases at three months after surgery. The capitolunate joint maintained congruity after surgery. The Mayo wrist score was 75 points, and the DASH (JSSH version) score for the two cases was 2.5 and 4.2 points, respectively. Radiolunate fusion using the vascularized radius bridging procedure is one of the satisfactory methods for treating advanced Kienböck disease, especially in Bain's grade 2A cases.

Abstract
Paraplegia associated with acute aortic dissection is one of the most serious complications. We experienced a case of Stanford type A acute aortic dissection with paraplegia and cardiac tamponade because the dissection was already thrombosed, conservative therapy was chosen. After drainage of pericardial effusion, a spinal drainage tube was inserted. Eleven days later, pulmonary embolism and re-dissection occurred, and an emergency operation was performed. Although the operation was successful, paraplegia did not improve. Even if type A acute aortic dissection is complicated with paraplegia, early surgical repair of aortic dissection should be considered, when paraplegia does not improve rapidly in spite of treatment.
