Abstract
Recent reports have shown that Staphylococcus aureus infection increases the expression of cytokines and cell adhesion molecules in endothelial cells and enhances leucocyte migration, thereby resulting in bacterial elimination. In this study, we analysed the production of the chemokine interleukin (IL)-8 in human umbilical vein endothelial cells (HUVEC) infected with several S. aureus strains by using reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay. We found that the avirulent strains (00-51 and 00-62) increased IL-8 production but the virulent strains (A17 and A151) decreased it at both the mRNA and protein levels. We considered that the inhibition of IL-8 production depended on certain inhibitory factor(s) secreted by bacteria. This was because S. aureus also abolished IL-8 expression in HUVEC treated with cytochalasin D, and the addition of culture supernatants of strains A17 and A151 decreased IL-8 production in HUVEC. This factor(s) in the bacterial culture supernatant inhibited both basal and tumour necrosis factor (TNF)-alpha-induced IL-8 production. In contrast, no inhibitory effect was observed on monocyte chemotactic protein-1 (MCP-1) production. These results indicate that S. aureus can down-regulate IL-8 release in endothelial cells through the secretion of inhibitory factor(s), and this may result in decreased neutrophil recruitment, thus interfering with the host immune response to bacterial infection.

Abstract
The JC virus (JCV) infects a large proportion of the population world wide and can cause progressive multifocal leucoencephalopathy in the context of immunodeficiency. Recent reports provide evidence that it may also be oncogenic. Here, JCV was examined by targeting its T-antigen in lung carcinomas (n=103) and normal lung tissues (n=18) by nested-PCR followed by Southern blot, real-time PCR, immunohistochemistry, in situ hybridization and in situ PCR. Additionally, expression of Ki-67, caspase-3, beta-catenin, p53, and Rb was analysed by immunohistochemistry on tissue microarrays of lung carcinomas. Copy numbers of JCV were compared with clinicopathological features. Normal lung tissue was positive significantly less frequently, and contained a lower copy number of JCV than lung carcinomas (p<0.05), and copies were lower in lung adenocarcinomas than in squamous, small or large cell carcinomas (p<0.05). In situ PCR and immunolabelling revealed JCV positivity in the nuclei of lung carcinoma cells. The JCV copy number correlated closely with sex, and expression of Ki-67 and membrane beta-catenin (p<0.05), but not with age, tumour size, pleural invasion, lymph node metastasis, expression of caspase-3, cytoplasmic beta-catenin, p53 or Rb, prognosis, smoking or cancer family history (p>0.05). Age and UICC staging were independent prognostic factors for lung carcinoma patients. These data suggest that JCV may be involved in lung carcinogenesis, especially in tumour types other than adenocarcinoma. Lung carcinomas with higher JCV copy numbers display high proliferation and down-regulation of cell adhesion mediated by membrane beta-catenin.

Abstract
OBJECTIVE Aberrant expression of maspin protein related to DNA hypomethylation in the promoter region is frequently observed in gallbladder carcinomas, whereas the non-tumorous gallbladder epithelium is maspin negative. We investigated maspin expression in non-tumorous gallbladder epithelium in patients with cholelithiasis. METHODS An immunohistochemical study of maspin expression was performed in 69 patients with cholelithiasis and 30 patients with gastric cancer without cholelithiasis. RESULTS Immunoreactivity for maspin was observed in focal and patchy regions of the gallbladder epithelium. Positive immunoreactivity for maspin was significantly associated with the presence of intestinal metaplasia in patients with cholelithiasis (p<0.05). CONCLUSION The high incidence of aberrant maspin expression in both intestinal metaplasia and carcinoma of the gallbladder supports the assumption that intestinal metaplasia of the gallbladder may predispose to gallbladder carcinoma.

Abstract
AIMS Secretory phospholipase A2 is associated with ischaemic injury in the human heart, but the distribution of type V secretory phospholipase A2 (sPLA2-V) remains unknown. The significance of sPLA2-V in myocardial infarction was investigated histopathologically. METHODS Sequential changes in the localization of sPLA2-V and its mRNA in myocardial tissues obtained from 30 autopsied hearts were examined by immunohistochemistry and in situ hybridization and compared with those of fibronectin, vascular endothelial growth factor (VEGF), interleukin (IL)-1beta, tumour necrosis factor (TNF)-alpha, and cyclooxygenase-2 (COX-2). RESULTS No expression of sPLA2-V was observed in normal heart, but it was promptly expressed in wavy myofibres positive for fibronectin just after the onset of infarction. sPLA2-V was subsequently expressed in ischaemic cardiomyocytes around the lesion. The expression decreased at the granulation tissue and disappeared at the chronic stage with scar formation. The distribution of the signal for sPLA2-V mRNA paralleled that of the protein. Ischaemic myocytes around the lesion expressed VEGF, IL-1beta, TNF-alpha and COX-2 at all stages. CONCLUSIONS sPLA2-V production in myocardium is limited to the acute phase of infarction. sPLA2-V may play a dual role, acting both to remove degraded cell-membrane through cooperative activity with COX-2 in necrotic areas and to attack ischaemic myocytes around the lesion via degradation of membrane phospholipids.

Abstract
Sixty-two cases of peripheral lung adenocarcinoma 2 cm or less in diameter were diagnosed as type A, B, or C according to Noguchi classifications by intraoperative frozen section diagnosis. Four of 19 type A were changed finally to type B by postoperative pathologic examination. Likewise 10 of 34 type B were changed finally to 1 type A, 8 type C, and 1 type D. Three of 9 type C were changed finally to 2 type B and 1 type D. Frozen section diagnosis for small peripheral lung adenocarcinoma has some special problems and limitations. Only cases of type A diagnosed by frozen section diagnosis should be permitted to undergo limited surgical resection.

Abstract
The rotational isomerism of 1,2-dichloroethane (DCE, CH2ClCH2Cl) adsorbed on Pt(111) was studied in the temperature range of 35-100 K using high-resolution electron energy loss spectroscopy and metastable atom electron spectroscopy. In the coverage below monolayer the physisorbed and chemisorbed species coexist at 35 K in the gauche and slightly distorted trans form, respectively. Owing to the direct Pt-Cl interactions, the nonbonding Cl 3p states of the chemisorbed DCE are split off, giving rise to degradation in symmetry from the pure trans form (C2h). The physisorbed gauche conformers are arranged with the C2 axis parallel (or heavily tilted) to the substrate and converted irreversibly to the pseudo-trans form by heating at 70 K. In the multilayer, the trans and gauche conformers exist at 35 K, where the former population is increased with increasing layer thickness. Upon annealing the bilayer at 80 K, the irreversible conversion takes place to yield a higher population of the gauche conformer in the topmost layer. The conformational stabilities and mutual changes of DCE adsorbed on a metal surface are discussed in terms of intramolecular rotational potential.

Abstract
We study experimentally the interaction of the shortest at present (23-fs) , relativistically intense (20-TW), tightly focused laser pulses with underdense plasma. MeV electrons constitute a two-temperature distribution due to different plasma wave-breaking processes at a plasma density of 10(20) cm(-3). These two groups of electrons are shown numerically to constitute bunches with very distinctive time durations.

Abstract
A 56-year-old man, who visited our hospital due to chest pain, was pointed out a large tumor, 60 mm in diameter, on the left superior mediastinum on the chest computed tomography (CT) scan. He was diagnosed as having mediastinal lymph nodes metastasis of adenocarcinoma through video-assisted thoracoscopic surgery (VATS) biopsy. He received induction chemoradiotherapy: cisplatin and paclitaxel were administered once per week for 2 weeks, and radiotherapy was simultaneously performed. No serious adverse reactions were noted. The ipsilateral mediastinal lymph nodes dissection was performed. Intraoperative frozen section analysis showed a small nodule in the left upper lobe, 5 mm in diameter, was adenocarcinoma. He was finally diagnosed as having mediastinal lymph nodes metastasis from the small adenocarcinoma of the lung, and left upper lobectomy was performed. Histopathological examination of the mediastinal lymph nodes showed no evidence of viable maligmant cell. Induction chemoradiotherapy with cisplatin and paclitaxel might be effective treatment for locally advanced non-small cell lung cancer.

Abstract
A 79-year-old male patient complicated with aortobronchial fistula after replacement of descending thoracic aorta with ringed graft. He underwent replacement of the aortic arch using a four branched vascular graft and open stent grafting to replace the descending thoracic aorta after removing the ringed-graft through median sternotomy. This procedure is useful for patients as the left thoracotomy is risky and the distal anastomotic site of the descending thoracic aorta is too far to anastomose.

Accidental exposure to acute high-dose total body neutron radiation is rare. We report a 35-year-old man exposed to a total body dose of 5.4 Gy neutron- and 8.5-13 Gy gamma-radiation in a radiation criticality accident. He received a blood stem cell transplant from his HLA-identical sister. There was bone marrow recovery with complete donor chimerism. Random chromatid breaks were observed in donor cells suggesting a bystander effect of neutron exposure. The subject died 82 days after the accident (75 days post transplant) from multi-organ failure.

Abstract
BACKGROUND/AIMS To ascertain the reliability of a newly developed office-based urine test, the RAPIRUN test, used for detection of H. pylori infection. METHODOLOGY Urine specimens from 142 consecutive patients undergoing gastroendoscopy (77 men, 65 women; mean 52.0 years) were tested with RAPIRUN at the same time. The total reaction time for the urine test is 20 min. None of the patients had received any H. pylori eradicating treatment. The H. pylori status was evaluated based on 5 different tests: culture, histology, biopsy urease test, 13C-urea breath test, and the RAPIRUN test. A commercial office-based kit using an immunochromatographic technique was used to examine urine samples for H. pylori antibody. H. pylori status was defined as positive when the culture was positive or if 2 of the other 3 tests (histology, biopsy urease test, and 13C-urea breath test were positive. RESULTS Of 93 patients with H. pylori infection, 88 were tested as positive by RAPIRUN (sensitivity 94.6%). Of 48 patients without infection, 43 were found to be negative by RAPIRUN (specificity 89.6%). One case with an invalid urine test was excluded. CONCLUSIONS This urine test is a rapid, inexpensive, reliable and easy-to-use tool for the diagnosis of H. pylori infection in untreated patients. It can be used for mass screening of patients' H. pylori status, particularly in children, postgastrectomy patients, uncooperative patients, and patients undergoing bismuth or proton pump inhibitor treatment.

Abstract
The forward and backward swimming speeds and periods of a Vibrio alginolyticus strain that has a single polar flagellum were measured. The backward swimming speeds were 1.5 times greater than the forward ones on average and the average period of backward swimming was shorter than forward swimming. However, the swimming speed and period were not correlated. Similar results were obtained for a mutant that has a 1.6 times longer flagellum on average.
