Abstract
BACKGROUND Lymphangioleiomyomatosis (LAM) is a rare disease caused by dysregulated activation of the mammalian target of rapamycin (mTOR). Sirolimus, an inhibitor of mTOR, has been reported to decrease the size of angiomyolipomas and stabilize pulmonary function in patients with LAM. However, the optimal dose for the treatment of LAM remains unclear. METHODS We conducted a retrospective, observational study of 15 patients with LAM who underwent sirolimus therapy for more than 6 months. The efficacy was evaluated by reviewing the patients' clinical courses, pulmonary function and chest radiologic findings before and after the initiation of sirolimus treatment. RESULTS All patients had blood trough levels of sirolimus lower than 5ng/mL. Sirolimus treatment improved the annual rates of change in FVC and FEV1 in the 9 patients who were free from chylous effusion (FVC, -101.0 vs. +190.0mL/y, p=0.046 and FEV1, -115.4 vs. +127.8mL/y, p=0.015). The remaining 7 patients had chylous effusion at the start of sirolimus treatment; the chylothorax resolved completely within 1-5 months of treatment in 6 of these cases. These results resembled those of previous studies in which blood trough levels of sirolimus ranged from 5 to 15ng/mL. CONCLUSIONS Low-dose sirolimus (trough level, 5ng/mL or less) performed as well as the higher doses used previously for improving pulmonary function and decreasing chylous effusion in patients with LAM.

Abstract
Thoracic endometriosis is a rare disease responsible for catamenial pneumothorax. The immunohistochemical features of thoracic endometriosis are not well understood. An immunohistochemical examination of 84 diaphragmatic specimens of catamenial pneumothorax using antibodies against estrogen receptor (ER), progesterone receptor (PgR), CD10 and smooth muscle actin (SMA) was conducted. The endometrial tissue was small, and focally located around the chasm of the tendon on the side of the thoracic cavity. Endometrial stroma were detected in 84/84 (100%) of the specimens, endometrial glands were detected in 21/84 (25%) and smooth muscle was detected in 1/84 (1.2%). The endometrial stroma exhibited positive staining for ER in 74/84 (88.1%) of the specimens, PgR in 84/84 (100%), CD10 in 74/84 (88.1%) and SMA in 46/84 (54.8%). Because thoracic endometriosis is small in size, and only 25% of the resected tissue specimens were accompanied with the endometrial gland, an immunohistochemical analysis can be useful for their detection. The fact that over half of the thoracic endometrial stroma showed positive staining for SMA, and the existence of thoracic endometriosis accompanied by smooth muscle, indicated that some part of the thoracic endometriosis may have the ability to differentiate into smooth muscle, although further studies are needed to confirm this hypothesis.

Abstract
We have revealed the fundamental mechanism of specific Cs(+) adsorption into Prussian blue (PB) in order to develop high-performance PB-based Cs(+) adsorbents in the wake of the Fukushima nuclear accident. We compared two types of PB nanoparticles with formulae of Fe(III)4[Fe(II)(CN)6]3·xH2O (x = 10-15) (PB-1) and (NH4)0.70Fe(III)1.10[Fe(II)(CN)6]·1.7H2O (PB-2) with respect to the Cs(+) adsorption ability. The synthesised PB-1, by a common stoichiometric aqueous reaction between 4Fe(3+) and 3[Fe(II)(CN)6](4-), showed much more efficient Cs(+) adsorption ability than did the commercially available PB-2. A high value of the number of waters of crystallization, x, of PB-1 was caused by a lot of defect sites (vacant sites) of [Fe(II)(CN)6](4-) moieties that were filled with coordination and crystallization water molecules. Hydrated Cs(+) ions were preferably adsorbed via the hydrophilic defect sites and accompanied by proton-elimination from the coordination water. The low number of hydrophilic sites of PB-2 was responsible for its insufficient Cs(+) adsorption ability.

Abstract
BACKGROUND The role of melanoma inhibitory activity 2 (MIA2) was examined in human oral squamous cell carcinoma (OSCC). METHODS MIA2 role was examined by immunohistochemistry of human OSCCs and knockdown studies using human 3 OSCC cell lines with MIA2 expression. RESULTS MIA2 expression was observed in 62 (66.7%) of 93 OSCCs and was associated with tumour expansion and nodal metastasis. Melanoma inhibitory activity 2 expression was inversely correlated with intratumoral infiltration of lymphocytes. Invasion and anti-apoptotic survival were reduced by MIA2 knockdown in HSC3 cells. MOLT-3 lymphocytes infiltrating the HSC3 cell layer was enhanced by MIA2 knockdown or MIA2 depletion with the antibody. In HSC3 cells, MIA2 knockdown decreased the expressions of vascular endothelial growth factor (VEGF), VEGF-C, and VEGF-D. The downregulation of VEGF-C and -D was caused by inhibition of p38 and extracellular signal-regulated kinase (ERK)1/2, respectively. Melanoma inhibitory activity 2 was co-precipitated with integrin α4 andα5 in HSC3 cells. Integrin α4 knockdown decreased p38 phosphorylation and increased apoptosis, whereas integrin α5 knockdown decreased c-Jun N-terminal kinase (JNK) phosphorylation and apoptosis. Inhibition of JNK decreased apoptosis in the HSC3 cells. CONCLUSION These findings suggest that the roles of MIA2 might be based on the variety of the integrins and the subtypes of mitogen-activated protein kinase.

Abstract
OBJECTIVE Prolonged air leaks in patients with spontaneous pneumothorax are not infrequent. The aim of this study was to assess the duration of air leaks and define the clinical variables associated with the therapeutic success of chest tube drainage for spontaneous pneumothorax. METHODS A total of 441 patients with spontaneous pneumothorax treated with chest tube drainage between 2008 and 2012 were retrospectively evaluated. The clinical differences between the patients successfully treated with drainage and those who required more invasive procedures were analyzed. RESULTS Invasive procedures, such as video-assisted thoracic surgery (n=121), fibrin glue administration through a chest tube (n=8) and pleurodesis with OK-432 (n=21), were performed in 34% (150/441) of the patients. The treatment rate of chest drainage alone was higher in the patients with initial pneumothorax (72%; 124/170) than in those with recurrent pneumothorax (62%; 167/271) (p=0.015). In addition, this rate was higher in the patients with moderate lung collapse (70%; 167/237) than in those with severe lung collapse (61%; 124/204) (p=0.032). CONCLUSION Patients with recurrent pneumothorax or severe lung collapse associated with prolonged air leakage are more likely to receive invasive procedures.

Abstract
The optimal dose of cisplatin (CDDP) for combination chemotherapy for the treatment of inoperable, advanced gastric cancer has yet to be established. We therefore performed a randomized study to compare the therapeutic usefulness of two dose levels of cisplatin. 5'-deoxy-5-fluorouridine (5'-DFUR 1,400 mg/m(2)/d) was given orally on days 1 to 4 and 15 to 18. Mitomycin C (MMC, 5.75 mg/m(2)/d) was injected intravenously on day 5. In addition, 80 mg/m2/d of CDDP (regimen A) or 60 mg/m(2)/d of CDDP (regimen B) was given by 2-h intravenous drip infusion on day 5. This treatment cycle was repeated every four weeks. Fifty-six patients were enrolled. Clinical response was evaluated in 32 patients (regimen A, 16 patients; regimen B? 16 patients) with measurable lesions. The response rate was significantly higher with regimen A (9 PR/16, 56.3%) than with regimen B (3 PR/16, 18.9%) (p=0.028, chi(2) test). Median survival was slightly but not significantly longer with regimen A (7.4 months) than with regimen B (6.3 months). Drug toxicity included myelosuppression and gastrointestinal symptoms, but there were no serious adverse reactions or differences in safety between the treatment regimens. Regimen A was associated with a high response rate and low toxicity. The optimal dose of CDDP in combination with 5'-DFUR and MMC for the treatment of advanced gastric cancer is regarded to be 80 mg/m(2).

Abstract
Surgical teleconferences using advanced academic networks are becoming common; however, reports regarding Internet teleconferencing using free software packages such as Skype, USTREAM, and Dropbox are very rare. Teleconferences concerning mainly surgical techniques were held five times between Fukuoka University Hospital and other institutions from April to September 2010. These teleconferences used Skype and USTREAM as videophones to establish communication. Both PowerPoint presentations and surgical videos were made. These presentation files were previously sent to all stations via mail, e-mail, or Dropbox, and shared. A slide-show was simultaneously performed following the presenter's cue in each station. All teleconferences were successfully completed, even though there were minor instances of the Skype link being broken for unknown reasons during the telecommunication. Internet surgical teleconferences using ordinary software are therefore considered to be sufficiently feasible. This method will become more convenient and common as the Internet environments advance.

Abstract
Intractable pneumothorax with interstitial pneumonia (IP) is famous for the disease finally to lead to death in case of persistent air leakage. It is because severe infection, respiratory insufficiency and tissue healing insufficiency by treatments with steroid hormones and immune-suppressants on IP. Pleurodesis is generally performed although the effect of it is questionable. It is important to stop immune-suppressants and reduce steroid hormones before the treatments to succeed in thoracoscopic surgery and thoracographic fibrin glue sealing method (TGF) if possible. Less invasive interventional treatments like TGF are recommendable because intractable pneumothorax with IP is in the high risk group to need to avoid surgery. Hand suturing, looping, covering and putting TachoComb on the air leak point instead of end-stapling should be performed in order to stop air leakage when forced to choose thoracoscopic surgery.

Abstract
578 Background: BV is widely used for treatment of metastatic colorectal cancer (mCRC) patients. Although BV was often administrated to mCRC patients in combination with oxaliplatin, optimal schedule remains unclear. Many mCRC patients cannot continue to use oxalipatin because of cumulative neurotoxity, which decreases patient's QOL and motivation.We postulated that modification of oxaliplatin schedule would improve TTF in intermittent oxaliplatin usage. Therefore, we planned to use BV with original OPTIMOX1 adiministration schedule; modified oxaliplatin dose (85 mg/m3). Methods: Patients were enrolled with the criteria excluding neuropathy, PS ≥ 1, or no previous usage of oxaliplatin and BV, and then were received modified FOLFOX6 regimen (L-OHP 85 mg/m2, l-LV 200 mg/m2, 5-FU 400 mg/m2 bolus, 5-FU 2,400 mg/m2 46h continuous infusion) plus BV (5 mg/kg) q2wks x 6 cycles, followed sLV5FU2 (omit L-OHP) plus BV x 12 cycles regimen. After that, oxaliplatin reintroduction was done and mFOLFOX6 plus BV regimen was continued until PD. The evaluation of antitumor effect was done according to RECIST Criteria. Results: 40 patients accrued this trial. Median age was 65 years old. PS0: 89.5%, male: 75%, female: 25%, colon: 65.8%, rectal: 31.6%,colon + rectal: 2.6%. During initial 6 cycles of chemotherapy, 90% patients could continue chemotherapy. Response rate was 50%, and clinical benefit (including SD) was 92.1%. During Intial 6 cycles, G3 neuropathy occurred 2.6%, and G2 were 5%. Most frequent toxicity (≥G3) was neutropenia (30.8%) and anorexia (5.3%). One patient could complete the scheduled regimen. This patient continued mFOLFOX6+BV for 12 cycles after reintroduction keeping with PS 0, and was received FOLFIRI+BV regimen as second-line chemotherapy. Further information are under examination. Conclusions: This administration schedule was well tolerated and could continue chemotherapy longer than usual method. sLV5FU2+BV regimen was not affected reintroduction rate and progression free survival. BV with mOPTIMOX1 regimen can be expected to become a good treatment options for mCRC patients. No significant financial relationships to disclose.

Abstract
BACKGROUND Birt-Hogg-Dubé syndrome (BHDS) is an inherited autosomal genodermatosis characterised by fibrofolliculomas of the skin, renal tumours and multiple lung cysts. Genetic studies have disclosed that the clinical picture as well as responsible germline FLCN mutations are diverse. OBJECTIVES BHDS may be caused by a germline deletion which cannot be detected by a conventional genetic approach. Real-time quantitative polymerase chain reaction (qPCR) may be able to identify such a mutation and thus provide us with a more accurate clinical picture of BHDS. METHODS This study analysed 36 patients with multiple lung cysts of undetermined causes. Denaturing high performance liquid chromatography (DHPLC) was applied for mutation screening. If no abnormality was detected by DHPLC, the amount of each FLCN exon in genome was quantified by qPCR. RESULTS An FLCN germline mutation was found in 23 (63.9%) of the 36 patients by DHPLC and direct sequencing (13 unique small nucleotide alterations which included 11 novel mutations). A large genomic deletion was identified in two of the remaining 13 patients by qPCR (one patient with exon 14 deletion and one patient with a deletion encompassing exons 9 to 14). Mutations including genomic deletions were most frequently identified in the 3'-end of the FLCN gene including exons 12 and 13 (13/25=52.0%). The BHDS patients whose multiple cysts prompted the diagnosis in this study showed a very low incidence of skin and renal involvement. CONCLUSIONS BHDS is due to large deletions as well as small nucleotide alterations. Racial differences may occur between Japanese and patients of European decent in terms of FLCN mutations and clinical manifestations.

Abstract
Six plant sources of hydrolyzable tannins (HT) or HT and condensed tannins (CT; designated as HT1, HT2, HT3, HT + CT1, HT + CT2, and HT + CT3) were evaluated to determine their effects in vitro on CH(4) production and on ruminal archaeal and protozoa populations, and to assess potential differences in biological activities between sources containing HT only or HT and CT. Samples HT1, HT2, and HT3 contained only HT, whereas samples HT + CT1, HT + CT2, and HT + CT3 contained HT and CT. In experiment 1, in vitro incubations with samples containing HT or HT + CT resulted in a decrease in CH(4) production of 0.6 and 5.5%, respectively, compared with that produced by incubations containing the added tannin binder polyethylene glycol-6000. Tannin also suppressed the population of methanogenic archaea in all incubations except those with HT2, with an average decrease of 11.6% in HT incubations (15.8, 7.09, and 12.0 in HT1, HT2, and HT3) and 28.6% in incubations containing HT + CT (35.0, 40.1, and 10.8 in HT + CT1, HT + CT2, and HT + CT3) when compared with incubations containing added polyethylene glycol-6000. The mean decrease in protozoal counts was 12.3% in HT and 36.2% in HT + CT incubations. Tannins increased in vitro pH, reduced total VFA concentrations, increased propionate concentrations, and decreased concentrations of iso-acids. In experiment 2, when a basal diet was incubated with graded levels of HT + CT1, HT + CT2, and HT + CT3, the total gas and CH4 production and archaeal and protozoal populations decreased as the concentration of tannins increased. Our results confirm that tannins suppress methanogenesis by reducing methanogenic populations in the rumen either directly or by reducing the protozoal population, thereby reducing methanogens symbiotically associated with the protozoal population. In addition, tannin sources containing both HT and CT were more potent in suppressing methanogenesis than those containing only HT.

Abstract
Reverse osmosis (RO) membrane is one of the most powerful tools for solving the global water crisis, and is used in a variety of water treatment scenes such as drinking water purification, waste-water treatment, boiler feed water production, ultra pure water production for semiconductor industry, etc. The desired performance of RO membrane varies according to quality of feed water being treated, and Toray has been developing RO membranes with suitable characteristic for each operating condition. RO membranes for seawater desalination and wastewater reclamation are especially regarded as most promising targets. Recently, high boron removal and energy saving RO membrane for seawater desalination and low fouling RO membrane for wastewater reclamation have been developed. In this paper, the prospect of attaining these renovative RO membrane, and furthermore, job references will be discussed.

Abstract
PURPOSE To describe in detail the characteristic chest computed tomography (CT) findings of Birt-Hogg-Dubé (BHD) syndrome. MATERIALS AND METHODS Thin-section chest CT scans of consecutive 12 patients with genetically diagnosed BHD syndrome were retrospectively evaluated by two observers, especially about the characteristics (distribution, number, size, shape and relation to pleura) of pulmonary cysts. Interobserver agreement in the identification of abnormalities on the CT images was achieved using the κ statistic, and the degree of interobserver correlation for the characterization of pulmonary cysts was assessed using the Spearman rank correlation coefficient. RESULTS Multiple pulmonary cysts were seen in all patients. The number of cysts in each patient was various (range, 29-407), and cysts of various sizes (from a few mm to 2 cm or more) were seen in all patient. 76.6% (mean) of cysts were irregular-shaped, and 40.5% (mean) of cysts were located along the pleura. The mean extent score of cysts was 13% of the whole lung, and the distribution of cysts was predominantly in the lower medial zone. Finally, cysts abutting or including the proximal portions of lower pulmonary arteries or veins were also seen in all patients. CONCLUSION Multiple, irregular-shaped cysts of various sizes with lower medial lung zone predominance are characteristic CT findings of BHD syndrome. Cysts abutting or including the proximal portions of lower pulmonary arteries or veins may also exist in this syndrome in a high probability.
