Abstract
BACKGROUND Combination therapy with docetaxel (DTX) and ramucirumab (RAM) has been used as a second-line treatment for advanced or recurrent lung cancer. However, there is insufficient evidence regarding the safety of angiogenesis inhibitors in older patients. OBJECTIVE This multicenter retrospective study aimed to investigate the efficacy and safety of second-line treatment regimens in older patients with advanced or recurrent non-small cell lung cancer (NSCLC). PATIENTS AND METHODS We retrospectively analyzed 145 patients aged ≥ 70 years with advanced or recurrent NSCLC treated with second-line chemotherapy after platinum-based therapy between April 1, 2016, and March 31, 2021. Patients were subdivided into the DTX + RAM (n = 38) and single-agent (n = 107) groups. RESULTS The median time to treatment failure was 6.3 months (95% confidence interval [CI] 3.6-9.6) in the DTX + RAM group and 2.3 months (95% CI 1.7-3.0) in the single-agent group (p < 0.01). The median overall survival was 15.9 months (95% CI 12.3-Not Achieved) in the DTX + RAM group and 9.4 months (95% CI 6.9-15.1) in the single-agent group (p = 0.01). Grade ≥ 3 adverse events frequency was not significantly different between the two groups, except for edema. Patients in the DTX + RAM group who did not discontinue treatment owing to adverse events exhibited the most favorable prognosis. CONCLUSIONS These findings suggest that the DTX + RAM combination is an effective second-line therapy for older patients with advanced or recurrent NSCLC, offering favorable efficacy without treatment discontinuation owing to adverse events.

Abstract
BACKGROUND Programmed death-ligand 1 (PD-L1) inhibitor plus platinum-etoposide chemotherapy is used as a first-line treatment for extensive-stage small cell lung cancer (ES-SCLC), regardless of age. OBJECTIVE We examined the role of the Geriatric 8 (G8) screening tool for evaluating treatment outcomes in patients with ES-SCLC treated with PD-L1 inhibitor plus platinum-etoposide chemotherapy as first-line therapy. PATIENTS AND METHODS Between September 2019 and October 2021, we prospectively evaluated patients with ES-SCLC treated with immunochemotherapy at ten institutions in Japan. The G8 score was assessed before treatment initiation. RESULTS We evaluated 44 patients with ES-SCLC. Patients with G8 score > 11 had longer overall survival (OS) than those with G8 score ≤ 11 (not reached versus 8.3 months; log-rank test, p = 0.005). In univariate and multivariate analyses, G8 score > 11 [hazard ratio (HR) 0.34; 95% confidence interval (CI) 0.15-0.75; p = 0.008 and HR 0.34; 95% CI 0.14-0.82; p = 0.02, respectively) and performance status (PS) of 2 (HR 5.42; 95% CI 2.08-14.2; p < 0.001 and HR 6.94; 95% CI 2.25-21.4; p < 0.001, respectively) were independent prognostic factors for OS. Among patients with good PS (0 or 1), the OS in patients with G8 score > 11 was significantly longer than that in patients with G8 score ≤ 11 (not reached versus 12.3 months; log-rank test, p = 0.02). CONCLUSIONS G8 score evaluation before treatment initiation was useful as a prognostic factor for ES-SCLC patients who received PD-L1 inhibitors and platinum-etoposide chemotherapy, even with good PS.

Abstract
BACKGROUND Lung cancer patients face a high risk of thromboembolism (TE), which is considered to be a poor prognostic factor. However, the impact of symptomatic cerebral infarction (CI) and pulmonary embolism (PE) on the prognosis of advanced non-small cell lung cancer (NSCLC) patients is not fully understood. METHODS We retrospectively identified 46 patients with advanced NSCLC who developed symptomatic CI or PE at five hospitals in Japan between January 2010 and December 2019. Prognosis and biomarker levels after incident CI and PE were investigated. RESULTS Of the 46 patients, 36 developed symptomatic CI, and 10 developed symptomatic PE. The median follow-up duration after incident CI and PE was 18.2 months. Although the proportion of Common Terminology Criteria for Adverse Events grade 4 tended to be higher in patients with PE than in those with CI (30% vs. 11%, p = 0.16), the overall survival (OS) after incident TE tended to be worse in patients with CI than in those with PE (median 2.3 months vs. 9.1 months, log-rank test p = 0.17). Multivariate analysis showed that OS after CI was worse in patients with high D-dimer (DD) levels than in those with low DD levels at the time of incident CI (median 1.3 months vs. 8.3 months, log-rank p < 0.001). CONCLUSIONS This retrospective study demonstrated that the prognosis of patients tended to be poorer after CI than after PE. The DD levels at the time of incident CI might be a promising predictor of clinical outcomes in advanced NSCLC patients who develop CI.

Abstract
Abstract
Study question
This study was to investigate effect of SERa on the fertilization rate, embryonic development after ICSI, and clinical and perinatal outcomes after single blastocyst transfer.
Summary answer
SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.
What is known already
Based on findings that the risk of congenital abnormalities in the newborn is higher in ovum with SERa in the cytoplasm, the Istanbul consensus workshop at the 2011 meeting of the ESHRE recommended against fertilizing ovum with SERa due to these risks. However, there have been several reports of healthy infants born from embryos derived from SERa, suggesting that, while more long-term follow-up is necessary, healthy births are possible from such embryos. In 2017, the 2011 recommendations were reviewed in the Alpha/ESHRE consensus (Vienna), which said the approach should be determined on a case-by-case basis.
Study design, size, duration
We retrospectively investigated 23,007 oocytes which was retrieved between January 2016 and March 2020. Of these, 1,038 oocytes (4.5%) with visible SERa comprised SERa (+), while 21,969 oocytes (95.5%) without SERa comprised SERa (-).
Participants/materials, setting, methods
SERa were observed under the microscopy after denudation. The rate of fertilization, good-quality day-3 embryos, good-quality day-5 blastocysts, and day-5, 6 or 7 blastocysts were evaluated for both groups. We also compared the rate of clinical pregnancy, live birth, miscarriage, and birth defects in single blastocyst transfer between SERa (+) derived 114 blastocysts and SERa (-) derived 6,290 blastocysts from January 2016 and December 2018.
Main results and the role of chance
The results are shown. 2PN fertilization rate outcomes after ICSI (SERa(-) eggs vs. SERa(+)eggs),81.4%(17,873/21,969) vs.79.4% (823/1,038),and good-quality day3 rate was 61.1%(10,927/17,873)vs.60.9% (501/823) which was not significantly different. Good-quality day5 blastocyst rate was 46.5% (7,876/16,955) vs. 39.8%(304/763), and day 5 blastocyst success rate was 60.8% (10,317/16,955) vs.54.3% (414/763), which were both significantly lower with SERa(+). (P < 0.001) The day 6 blastocyst success rate was 69.9% (11,849/16,955) vs. 65.5% (500/763) (P = 0.01), and the day 7 blastocyst success rate was 70.9% (12,024/16,955) vs. 67.5% (515/763) (P = 0.04), which were all significantly lower with SERa(+).The clinical pregnancy rate was 39.4% (2,481/6,290) vs. 35.1% (40/114), the live birth rate was 27.7% (1,745/6,290) vs. 26.3% (30/114), and the miscarriage rate was 27.5% (683/2,481) vs. 20.0% (8/40) and the congenital abnormality rate was 1.6% (29/1,757) vs. 0% (0/30) for SERa(-) embryos and SERa(+) embryos, respectively, which were not significantly different. Blastocyst derived from oocytes with SERa has similar clinical and perinatal outcomes with those of oocytes without SERa. Significant differences were examined using the chi-squared test, with p < 0.05, indicating a significant difference.
Limitations, reasons for caution
Embryos derived SERa (+) were transferred when the patient did not want any more oocytes retrievals, no embryos derived SERa (-) were available, and only if the couple desired embryo transfer after the problems associated with SERa (+) embryos were fully explained.
Wider implications of the findings
To the best of our knowledge, this study is the largest number of live births investigating the outcome of SERa (+) derived embryos. SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.

Abstract
The preceding propagation of turbulence pulses has been observed for the first time in heat avalanche events during the collapse of the electron internal transport barrier (e-ITB) in the Large Helical Device. The turbulence and heat pulses are generated near the foot of the e-ITB and propagate to the peripheral region within a much shorter time than the diffusion timescale. The propagation speed of the turbulence pulse is approximately 10 km/s, which is faster than that of the heat pulse propagating at a speed of 1.5 km/s. The heat pulse propagates at approximately the same speed as that in the theoretical prediction, whereas the turbulence pulse propagates one order of magnitude faster than that in the prediction, thereby providing important insights into the physics of non-local transport.

Abstract
Turbulence spreading into the edge stochastic magnetic layer induced by magnetic fluctuation is observed at the sharp boundary region in the large helical device. The density fluctuation excited at the sharp boundary region with a large pressure gradient does not propagate into the boundary region due to the blocking of turbulence spreading by the large second derivative of the pressure gradient. Once the magnetic fluctuation appears at the boundary, the density fluctuation begins to penetrate the edge stochastic layer and the second derivative of the pressure gradient also decreases. The increase of density fluctuation in this layer results in the broadening and reduction of the peak divertor heat load. It is demonstrated that magnetic fluctuation plays a key role in controlling the turbulence spreading at the boundary of plasma which contributes to the reduction of divertor heat load.

Abstract
In high-frequency pulsed magnets, such as kickers in particle accelerators, it is essential to reduce eddy currents that could be induced in the magnet core during excitation not to distort and attenuate the magnetic field pulse. A novel iron lamination scheme with additional interlaminar insulation is proposed for the magnet core of such pulsed magnets. A laminated steel sheet core is formed by alternately stacking thin steel and insulation sheets. For application to matched kicker magnets for accelerators, test magnets with the new and conventional iron lamination were designed, assembled, and extensively evaluated. The pulsed magnetic field waveforms of two test magnets with the new lamination successfully matched to below 0.1% over the entire pulse duration, which was significantly better than those with the conventional lamination. Among the applications of the developed high-frequency pulsed magnets, beam injection kickers for the coming next generation light sources and future colliders, where suppression of the transient stored-beam oscillation during beam injection is crucial, are considered to be promising.

Abstract
The standard treatment regimen has not yet been established for advanced pulmonary large cell neuroendocrine carcinoma (LCNEC) because of its rarity. LCNEC can be subdivided into 2 mutually exclusive molecular subgroups: STK11/KEAP1 and TP53 mutated with high neuroendocrine expression and transcriptional profile of ASCL1high/DLL3high/NOTCHlow (non-small cell lung carcinoma, NSCLC-like) or RB1 and TP53 mutated with reduced neuroendocrine markers and transcriptional pattern of ASCL1low/DLL3low/NOTCHhigh (small cell lung cancer, SCLC-like). Model-based clustering shows that SCLC has subdivided into 2 major proteomic subsets defined by either TTF-1high/c-MYClow or TTF-1low/c-MYChigh, which may correspond to 2 mutually exclusive molecular subgroups: NSCLC-like or SCLC-like, respectively. We herein investigated whether TTF-1 and c-MYC could be applied to LCNEC to identify distinct subsets immunohistochemically and assessed DLL3 expression in these subsets. The protein expression profile may be useful to select patients for potential efficacy of targeted therapies including aurora kinase inhibitors for MYC alterations or anti-DLL3 antibody-drug conjugates. TTF-1 and c-MYC expression was mutually exclusive in 25 of 27 (93%) cases; TTF-1+/c-MYC- in 10, TTF-1-/c-MYC+ in 15, and TTF-1+/c-MYC+ in 2. DLL3 expression was seen in 15 of 27 cases (56%). All 12 TTF-1+ LCNEC cases were positive for DLL3. Three of 15 (20%) TTF-1-/c-MYC+ cases showed DLL3 positivity. LCNEC could be separated into 2 subsets proteomically defined by TTF-1 and c-MYC expression, which may be suitable to guide treatment selection including aurora kinase inhibitors for c-MYC+ cases. TTF-1 positivity can serve as a surrogate marker for DLL3, but caution is necessary as 20% of TTF-1- cases showed DLL3 positivity.

Abstract
Transbronchial diagnosis of unexposed lung tumours is challenging in clinical practice. Although modified transbronchial needle aspiration (TBNA) is used for this purpose, the diagnostic yield is unsatisfactory. In such cases, conventional endobronchial ultrasonography with a guide sheath and transbronchial biopsy (TBB) is also ineffective. We found TBB was feasible by placing a guide sheath with a thin transbronchial needle into the tumours. We report two cases of unexposed tumours diagnosed successfully with this technique. Case 1 presents a typical carcinoid in the peripheral lung. Case 2 presents a squamous cell carcinoma at the third bifurcation of the right lung. TBB samples obtained this way were larger than TBNA samples. Moreover, multiple TBBs were possible once the guide sheath was inserted intratumourally. In the modern era of precision medicine, larger amounts of tissues are required for multiple downstream analyses. This novel technique will make a significant contribution towards diagnosing unexposed lung tumours.

Abstract
A 49-year-old woman with an abnormal shadow on her chest X-ray visited our hospital. Chest computed tomography revealed a 13-mm diameter nodule in S9 on the right and a 47-mm diameter mass in segment (S) 1 + 2 on the left. She underwent transbronchial biopsy, which revealed that both tumours had the same histology of papillary adenocarcinoma. The indications of radical surgery differ between metastatic and multiple primary cancers; however, the epidermal growth factor receptor mutation screenings turned out to be discordant, with exon 19 deletion in the right and exon 21 L858R mutation in the left tumour. This is the first case report of a pre-operative diagnosis of multiple primary adenocarcinomas eligible for radical surgery. Thorough assessment is recommended in cases wherein the differential diagnosis is considered to be a factor for surgical indication. Genetic screening provides additional diagnostic information despite the presence of tumours manifesting the same histological type.

Abstract
Lessons Learned. In terms of efficacy and safety, good results were obtained with S‐1 and paclitaxel (PTX) combination therapy. The findings suggest that S‐1 and PTX combination therapy is a feasible treatment option in patients with previously treated non‐small cell lung cancer.
Background. Although monotherapy with cytotoxic agents, including docetaxel and pemetrexed, is recommended for patients with previously treated advanced non‐small cell lung cancer (NSCLC), its outcomes are unsatisfactory. S‐1 is an oral fluoropyrimidine agent that consists of tegafur, 5‐ chloro‐2, 4‐dihydroxypyridine, and potassium oxonate. S‐1 is approved for patients with gastric cancer in 7 Asian countries and 15 European countries. It is also approved for patients with eight type of cancers, including NSCLC, in Japan. We evaluated the efficacy and toxicity of S‐1 and paclitaxel (PTX) combination therapy in patients with previously treated NSCLC. Methods. Oral S‐1 was administered thrice weekly on days 1–14 at 80, 100, and 120 mg/day in patients with body surface areas of <1.25, 1.25–1.5, and >1.5 m2, respectively. PTX was administered at 80 mg/m2 on days 1 and 8. Primary endpoint was response rate, and secondary endpoints were progression‐free survival (PFS), overall survival (OS), and safety. Results. Forty patients were enrolled, with response and disease control rates of 27.5% and 75.0%, respectively (Fig. 1). Median PFS and OS were 6.5 and 20.7 months, respectively. Grade 3/4 anemia and thrombocytopenia were seen in five (12%) and one (2%) patients, respectively. Febrile neutropenia occurred in three patients (7%). Common grade 3/4 nonhematological toxicities were stomatitis (5% of patients), diarrhea (7% of patients), and interstitial lung disease (one patient). No treatment‐related deaths were observed. Conclusion. This S‐1 and PTX cotherapy dose and schedule showed satisfactory efficacy, with mild toxicities, in patients with previously treated advanced NSCLC.

Lessons Learned. Coadministration of S‐1 and paclitaxel in elderly patients with advanced non‐small cell lung cancer showed favorable efficacy. Coadministration of S‐1 and paclitaxel in elderly patients with advanced non‐small lung cancer showed tolerable toxicity.
Background. Although monotherapy with cytotoxic agents including docetaxel or vinorelbine are recommended for elderly patients with advanced non‐small cell lung cancer (NSCLC), the outcome is not satisfactory. We evaluated the efficacy and safety of S‐1 and paclitaxel (PTX) as a first‐line cotreatment in elderly patients with advanced NSCLC. Methods. Oral S‐1 was administered on days 1–14 every 3 weeks at 80, 100, and 120 mg per day for patients with body surface area < 1.25 m2, 1.25–1.5 m2, and > 1.5 m2, respectively. PTX was administered at 80 mg/m2 on days 1 and 8. The primary endpoint was response rate, and secondary endpoints were progression‐free survival (PFS), overall survival (OS), and safety. Results. Seventeen patients were enrolled with response and disease control rates of 47.1% and 88.2%, respectively. Median PFS and OS were 5.6 and 35.0 months, respectively. Hematological grade 3 or 4 toxicities included leukopenia (55.8%), neutropenia (52.9%), febrile neutropenia (11.8%), and anemia (11.8%). Nonhematological grade 3 toxicities included stomatitis (23.5%), diarrhea (5.9%), and interstitial lung disease (5.9%), and grade 5 toxicities included interstitial lung disease (5.9%). Conclusion. This S‐1 and PTX cotherapy dose and schedule showed satisfactory efficacy with mild toxicities in elderly patients with advanced NSCLC.

Abstract
This phase I study was aimed at determining the maximum tolerated dose (MTD) and recommended dose (RD) for oral S-1 plus paclitaxel combination therapy in elderly patients with non-small cell lung cancer (NSCLC). Chemotherapy-naïve patients (age, >70 years) with stage III/IV NSCLC were treated with paclitaxel intravenously at four dose levels (DLs), 60, 70, 80, and 90 mg/m2, on day 1 and 8, and with S-1 (80 mg/m2) orally on days 1-14 every 3 weeks. MTD was defined as the dose at which two of the initial three patients experienced dose-limiting toxicities (DLTs). Three patients were added when the initial three patients experienced DLTs. The dose administered in three of the six patients with DLTs met the definition of MTD. The RD was defined as a dose 1 DL below the MTD. Fifteen patients including six on DL 1 and three each on DLs 2, 3, and 4 were enrolled. One patient experienced a DLT (febrile neutropenia) at DL 1. The remaining DLTs were noted at DL 4 (in one patient each): febrile neutropenia, grade (G) 3 skin rash, G3 diarrhea, G3 stomatitis, and G3 international normalized ratio (INR) elevation. The MTD of paclitaxel was 90 mg/m2. The RD for both S-1 and paclitaxel was 80 mg/m2 (DL 3). The response rate was 45.5% (8 of 15 patients achieved a partial response). In conclusion, the RD of both S-1 and paclitaxel was 80 mg/m2 in the combination therapy for chemotherapy-naïve patients with advanced NSCLC.

Abstract
BACKGROUND/AIM The purpose of this trial was to evaluate the feasibility and efficacy of alternating platinum-based doublet chemotherapy with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with EGFR-mutant non-small cell lung cancer (NSCLC). PATIENTS AND METHODS Chemotherapy-naive patients with advanced NSCLC harboring an EGFR mutation were enrolled. All patients underwent induction chemotherapy by sequentially alternating pemetrexed/cisplatin/bevacizumab and EGFR-TKIs followed by maintenance therapy with pemetrexed/bevacizumab and EGFR-TKIs. The primary outcome was the completion rate of the induction therapy. RESULTS Eighteen eligible patients were enrolled between May 2011 and March 2016. The completion rate of induction therapy was 72.2% (13/18). Unfortunately, one patient developed grade 4 acute renal injury, but no other serious complications concerning this protocol were observed. Furthermore, diarrhea, rashes, and hematological adverse effects were mild. CONCLUSION The completion rate of induction therapy was promising. Alternating chemotherapy and EGFR-TKIs should be further investigated regarding feasibility and efficacy.

Abstract
A 73-year-old male who underwent splenectomy was diagnosed with splenic non-caseating granuloma in May 201X, and sarcoidosis was disregarded from the differential diagnosis. Owing to the persisting inflammation, the patient was carefully followed up with no treatment. Four months post splenectomy, the patient was hospitalized due to progressive dyspnea. Chest computed tomography revealed an encapsulated pleural effusion and lymphocytic infiltration in the left lower lung, with subclavian and mediastinal lymphadenopathy. Although the patient was treated with antibiotics, his condition showed no improvement; therefore, prednisolone 40 mg was administered, resulting in lung lesion improvement. A re-examination of the tissue obtained from the previously removed spleen revealed splenic marginal zone lymphoma (SMZL), a specific low-grade, small B-cell lymphoma. As a result, the patient was treated with rituximab combined with chemotherapy. During the fifth course of the chemotherapy, a subcutaneous abscess appeared in the cervical region, and Mycobacterium shigaense was isolated from the pus discharge, suggesting that the splenic granulomatous lesion formed due to M.shigaense, and dissemination of the Mycobacterium infection occurred following splenectomy and chemotherapy, when the patient was immunosuppressed. Overall, we consider that SMZL developed because of chronic inflammation resulting from a nontuberculous mycobacterial infection.

Abstract
The resistive interchange mode destabilized by the resonant interaction with the trapped energetic ions is fully suppressed when the injected power of electron cyclotron heating exceeds a certain threshold. It is shown for the first time that the complete stabilization of the energetic-particle-driven mode without relaxing the energetic particle (EP) pressure gradient is possible by reducing the radial width of the eigenmodes δ_{w}, especially when δ_{w} narrows to a small enough value relative to the finite orbit width of EP.

Abstract
Combined treatment strategies based on magnetic nanoparticles (MNPs) with near infrared ray (NIR) biophotonic possess tremendous potential for non-invasive therapeutic approach. Nonetheless, investigations in this direction have been limited to peripheral body region and little is known about the potential biomedical application of this approach for brain. Here we report that transient NIR exposure is dissipation-free and has no adverse effect on the viability and plasticity of major brain cells in the presence or absence superparamagnetic nanoparticles. The 808 nm NIR laser module with thermocouple was employed for functional studies upon NIR exposure to brain cells. Magnetic nanoparticles were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), dynamic laser scattering (DLS), and vibrating sample magnetometer (VSM). Brain cells viability and plasticity were analyzed using electric cell-substrate impedance sensing system, cytotoxicity evaluation, and confocal microscopy. When efficacious non-invasive photobiomodulation and neuro-therapeutical targeting and monitoring to brain remain a formidable task, the discovery of this dissipation-free, transient NIR photonic approach for brain cells possesses remarkable potential to add new dimension.

Abstract
SETTING Lusaka, Zambia. OBJECTIVE To assess the actual treatment outcomes of 'transfer out' (TO) cases at a diagnostic centre in Lusaka, in the third and fourth quarters of 2012, and to see the impact of this cross-check in treatment success rates (TSR) in 2013 and early 2014. DESIGN AND METHOD In this retrospective cohort study, treatment outcomes for new bacteriologically positive tuberculosis (TB) cases referred from the diagnostic centre were reviewed and compared with those at the receiving treatment units. RESULTS Of 49 (58%) cases referred to three treatment units, the treatment outcomes of nine had to be updated at the diagnostic centre, which reduced the proportion of TO cases from 17.6% to 11.8% and increased the TSR to 70.6% from 64.7%. CONCLUSION The review and cross-checking of the TB registers at the diagnostic and treatment units led to a significant reduction in non-assessed cases, suggesting that the TB registers in the diagnostic and treatment units should be cross-checked regularly. There is also need for a complementary intervention to reduce the proportion of TOs associated with high loss to follow-up and non-evaluated TO rates.

Abstract
Aims This retrospective cohort study compared the results of vascularised and non-vascularised anterior sliding tibial grafts for the treatment of osteoarthritis (OA)of the ankle secondary to osteonecrosis of the talus. Patients and Methods We reviewed the clinical and radiological outcomes of 27 patients who underwent arthrodesis with either vascularised or non-vascularised (conventional) grafts, comparing the outcomes (clinical scores, proportion with successful union and time to union) between the two groups. The clinical outcome was assessed using the Mazur and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores. The mean follow-up was 35 months (24 to 68). Results The mean outcome scores increased significantly in both groups. In the vascularised graft group, the mean Mazur score improved from 36.9 to 74.6 and the mean AOFAS scale improved from 49.6 to 80.1. In the conventional arthrodesis group, the mean Mazur score improved from 35.5 to 65 and the mean AOFAS scale from 49.2 to 67.6. Complete fusion was achieved in 13 patients (76%) in the vascularised group, but only four (40%) in the conventional group. The clinical outcomes and proportion achieving union were significantly better in the vascularised group compared with the conventional arthrodesis group, although time to union was similar in the two groups. Take home message: Vascularised sliding tibial grafts may be used to achieve arthrodesis in patients with OA of the ankle secondary to osteonecrosis of the talus.

Abstract
A new method of vascularised tibial grafting has been developed for the treatment of avascular necrosis (AVN) of the talus and secondary osteoarthritis (OA) of the ankle. We used 40 cadavers to identify the vascular anatomy of the distal tibia in order to establish how to elevate a vascularised tibial graft safely. Between 2008 and 2012, eight patients (three male, five female, mean age 50 years; 26 to 68) with isolated AVN of the talus and 12 patients (four male, eight female, mean age 58 years; 23 to 76) with secondary OA underwent vascularised bone grafting from the distal tibia either to revascularise the talus or for arthrodesis. The radiological and clinical outcomes were evaluated at a mean follow-up of 31 months (24 to 62). The peri-malleolar arterial arch was confirmed in the cadaveric study. A vascularised bone graft could be elevated safely using the peri-malleolar pedicle. The clinical outcomes for the group with AVN of the talus assessed with the mean Mazur ankle grading scores, improved significantly from 39 points (21 to 48) pre-operatively to 81 points (73 to 90) at the final follow-up (p = 0.01). In all eight revascularisations, bone healing was obtained without progression to talar collapse, and union was established in 11 of 12 vascularised arthrodeses at a mean follow-up of 34 months (24 to 58). MRI showed revascularisation of the talus in all patients. We conclude that a vascularised tibial graft can be used both for revascularisation of the talus and for the arthrodesis of the ankle in patients with OA secondary to AVN of the talus.

Abstract
A fast two-dimensional soft X-ray camera using silicon photo diode array is being developed in order to investigate high frequency MHD instability with high mode number. The advantage of the adopted diode is a large sensor area of 10 mm × 10 mm and small diode capacitance which enable us to measure signals with the short response time. The characteristic of the prototype is summarized as follows: Channel number is 6 × 8 = 48, detection range 1∼10 keV, the spatial resolution 128 mm at the plasma location, and frequency range DC∼100 kHz. Synthetic image of the prototype in the Large Helical Device is estimated by using perturbation model of MHD mode.

Abstract
We and others have shown that epithelial Na(+) channels (ENaC) in alveolar type 2 (AT2) cells are activated by β2 agonists, steroid hormones, elevated oxygen tension, and by dopamine. Although acetylcholine receptors (AChRs) have been previously described in the lung, there are few reports of whether cholinergic agonists alter sodium transport in the alveolar epithelium. Therefore, we investigated how cholinergic receptors regulate ENaC activity in primary cultures of rat AT2 cells using cell-attached patch-clamp recordings to assess ENaC activity. We found that the muscarinic agonists, carbachol (CCh) and oxotremorine, activated ENaC in a dose-dependent manner but that nicotine did not. CCh-induced activation of ENaC was blocked by atropine. Western blotting and immunohistochemistry suggested that muscarinic M2 and M3 receptors (mAChRs) but not nicotinic receptors were present in AT2 cells. Endogenous RhoA and GTP-RhoA increased in response to CCh and the increase was reduced by pretreatment with atropine. We showed that Y-27632, an inhibitor of Rho-associated protein kinase (ROCK), abolished endogenous ENaC activity and inhibited the activation of ENaC by CCh. We also showed that ROCK signaling was necessary for ENaC stability in 2F3 cells, a model for AT2 cells. Our results showed that muscarinic agonists activated ENaC in rat AT2 cells through M2 and/or M3 mAChRs probably via a RhoA/ROCK signaling pathway.

Abstract
The beating cilia play a key role in lung mucociliary transport. The ciliary beating frequency (CBF) and ciliary bend amplitude (CBA) of isolated mouse bronchiolar ciliary cells were measured using a light microscope equipped with a high-speed camera (500 Hz). Procaterol (aβ(2)-agonist) increased CBA and CBF in a dose dependent manner via cAMP. The time course of CBA increase is distinct from that of CBF increase: procaterol at 10 nM first increased CBA and then CBF. Moreover, 10 pM procaterol increased CBA, not CBF, whereas 10 nM procaterol increased both CBA and CBF. Concentration-response studies of procaterol demonstrated that the CBA curve was shifted to a lower concentration than the CBF curve, which suggests that CBA regulation is different from CBF regulation. Measurements of microbead movements on the bronchiole of lung slices revealed that 10 pM procaterol increased the rate of ciliary transport by 37% and 10 nM procaterol increased it by 70%. In conclusion, we have shown that increased CBA is of particular importance for increasing the bronchiolar ciliary transport rate, although CBF also plays a role in increasing it.

Abstract
ABSTRACTRecent advances in understanding the ALE (atomic layer epitaxy) growth of ZnSe, ZnS and ZnTe are reviewed. The Ideal ALE growth is obtained in the substrate temperature range of 250–350°C for ZnSe. In the ALE growth of ZnSe and ZnTe, a unique self-limiting mechanism is observed, in which the deposition rate saturates at 0.5 monolayer per cycle. Furthermore, applications of ALE of II–VI compounds to the growth of strained layer superlattices are also reviewed.

Abstract
We examine whether alveolar cells can control release of O(2)(-) through regulated NADPH oxidase (NOX) 2 (NOX2) activity to maintain lung fluid homeostasis. Using FACS to purify alveolar epithelial cells, we show that type 1 cells robustly express each of the critical NOX components that catalyze the production of O(2)(-) (NOX2 or gp91(phox), p22(phox), p67(phox), p47(phox), and p40(phox) subunits) as well as Rac1 at substantially higher levels than type 2 cells. Immunohistochemical labeling of lung tissue shows that Rac1 expression is cytoplasmic and resides near the apical surface of type 1 cells, whereas NOX2 coimmunoprecipitates with epithelial sodium channel (ENaC). Since Rac1 is a known regulator of NOX2, and hence O(2)(-) release, we tested whether inhibition or activation of Rac1 influenced ENaC activity. Indeed, 1 microM NSC23766 inhibition of Rac1 decreased O(2)(-) output in lung cells and significantly decreased ENaC activity from 0.87 +/- 0.16 to 0.52 +/- 0.16 [mean number of channels (N) and single-channel open probability (P(o)) (NP(o)) +/- SE, n = 6; P < 0.05] in type 2 cells. NSC23766 (10 microM) decreased ENaC NP(o) from 1.16 +/- 0.27 to 0.38 +/- 0.10 (n = 6 in type 1 cells). Conversely, 10 ng/ml EGF (a known stimulator of both Rac1 and O(2)(-) release) increased ENaC NP(o) values in both type 1 and 2 cells. NP(o) values increased from 0.48 +/- 0.21 to 0.91 +/- 0.28 in type 2 cells (P < 0.05; n = 10). In type 1 cells, ENaC activity also significantly increased from 0.40 +/- 0.15 to 0.60 +/- 0.23 following EGF treatment (n = 7). Sequestering O(2)(-) using 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) compound prevented EGF activation of ENaC in both type 1 and 2 cells. In conclusion, we report that Rac1-mediated NOX2 activity is an important component in O(2)(-) regulation of ENaC.

Abstract
UNLABELLED We performed an intravenous glucose tolerance test (IVGTT) after the administration of triphenyltin chloride (TPTCl-Ad) in hamsters in order to confirm the presence of glucose intolerance and to clarify the pathogenesis of TPTCl-induced glucose intolerance. On the 1st, 2nd, 3rd, 4th and 7th days after TPTCl-Ad or the administration of sesame oil alone as a control, glucose was injected at a dose of 0.05 g glucose/100 g B.W., and then PG, IRI and TG were measured on 0, 1, 2, 3, 5 and 10 min after IVGTT. The TPT concentration in the pancreas was measured by gaschromatography and the morphological findings with a transmission electron microscope were compared between the TPTCl-Ad and the control hamsters. FPG on the 1st and the 2nd days after TPTCl-Ad were significantly higher than those in control, but those on the 4th and the 7th day recovered up to the control level. In contrast, basal IRI levels showed reciprocal results compared to the FPG levels. delta IRI/ delta PG on the 1st day after TPTCl-Ad was significantly reduced compared to the control. Fasting TG on the 1st day after TPTCl-Ad was much higher than the control. TPT-concentration on the 1st day after TPTCl-Ad showed peak values and its concentration gradually decreased. Electron microscopic findings in the pancreas after TPTCl-Ad indicated neither destruction nor lymphocyte infiltration of the pancreas. CONCLUSIONS The present data suggest that the administration of TPTCl in hamsters induces a functional transient damage on islet cells but not a morphological disorder, which shows an essentially different nature from the change in the pancreas induced by viral infection or by a large amount of streptozotocin.

Abstract
Apoptosis plays an important role in acute lung injury (ALI), and alveolar macrophages (AMs) are known to secrete proinflammatory cytokines and promote alveolar inflammation. The authors have previously reported that AMs can be depleted by inhalation of 1 mM 2-chloroadenosine (2-CA). In this study, the authors evaluated the effect of AM depletion by 2-CA inhalation on apoptosis in Candida-induced ALI. The results of in situ terminal deoxynucleotidyl transferase-mediated dUTP biotin nick end-labeling (TUNEL) and immunohistochemical studies and measurement of cytokine levels and caspase 3 activities in lung homogenates indicated that the Fas-FasL system and apoptosis of alveolar epithelial cells are suppressed by depletion of AMs by 2-CA inhalation.

Abstract
We report the effects of new N-acylated ambroxol derivatives (TEI-588a, TEI-588b, TEI-589a, TEI-589b, TEI-602a and TEI-602b: a, aromatic amine-acylated derivative; b, aliphatic amine-acylated derivative) induced from ambroxol (a mucolytic agent to treat human lung diseases) on Cl(-) secretion in human submucosal serous Calu-3 cells under a Na(+)/K(+)/2Cl(-) cotransporter-1 (NKCC1)-mediated hyper-secreting condition. TEI-589a, TEI-589b and TEI-602a diminished hyper-secretion of Cl(-) by diminishing the activity of NKCC1 without blockade of apical Cl(-) channel (TEI-589a>TEI-602a>TEI-589b), while any other tested compounds including ambroxol had no effects on Cl(-) secretion. These indicate that the inhibitory action of an aromatic amine-acylated derivative on Cl(-) secretion is stronger that that of an aliphatic amine-acylated derivative, and that 3-(2,5-dimethyl)furoyl group has a strong action in inhibition of Cl(-) secretion than cyclopropanoyl group. We here indicate that TEI-589a, TEI-589b and TEI-602a reduce hyper-secretion to an appropriate level in the airway, providing a possibility that the compound can be an effective drug in airway obstructive diseases including COPD by reducing the airway resistance under a hyper-secreting condition.

Abstract
Aspirin exerts anti-thrombotic action by acetylating and inactivating cyclooxygenase-1, preventing the production of thromboxane A2 in platelets. Through this inhibition of platelet function, aspirin is considered as a preventative of ischemic diseases such as coronary and cerebral infarction. However, many studies have revealed that aspirin has other beneficial actions in addition to its anti-platelet activity. For example, aspirin may confer some benefit against colorectal cancer. Here, we discuss the involvement of inflammation in atherosclerosis and how aspirin exerts its beneficial actions in atherosclerotic diseases and cancer.

Abstract
Ageing leads to immune system dysfunction and the accumulation of autoantibodies. Because the rapid phagocytic clearance of apoptotic cells is required to prevent the development of autoimmunity, we examined the relative clearance of apoptotic material in young and aged mice using two independent assays. First, 2-year-old mice were found to be impaired in their ability to clear apoptotic keratinocytes following ultraviolet irradiation of the skin. Secondly, peritoneal macrophages exposed to apoptotic Jurkat T cells in vivo displayed diminished phagocytic activity in aged mice compared with 8-week-old mice. Consistent with these findings, aged mice exhibited signs of autoimmunity with the appearance of anti-nuclear antibodies and increased kidney glomerular size as well as complement deposits within the glomeruli. In vitro assays revealed that the pretreatment of macrophages with the serum from aged mice led to a reduction in their ability to phagocytose apoptotic bodies compared with macrophages treated with serum from young mice. These data show that the ageing process is accompanied by a diminished ability to clear apoptotic debris. This accumulation of apoptotic debris could contribute to immune system dysfunction that occurs in aged organisms.

Abstract
Adiponectin is an adipocyte-derived collectin that acts on a wide range of tissues including liver, brain, heart, and vascular endothelium. To date, little is known about the actions of adiponectin in the lung. Herein, we demonstrate that adiponectin is present in lung lining fluid and that adiponectin deficiency leads to increases in proinflammatory mediators and an emphysema-like phenotype in the mouse lung. Alveolar macrophages from adiponectin-deficient mice spontaneously display increased production of tumor necrosis factor-alpha (TNF-alpha) and matrix metalloproteinase (MMP-12) activity. Consistent with these observations, we found that pretreatment of alveolar macrophages with adiponectin leads to TNF-alpha and MMP-12 suppression. Together, our findings show that adiponectin leads to macrophage suppression in the lung and suggest that adiponectin-deficient states may contribute to the pathogenesis of inflammatory lung conditions such as emphysema.

Abstract
Excessive nitric oxide (NO) generated by inducible nitric oxide synthase (iNOS) aggravates acute lung injury (ALI) by producing peroxynitrite. We previously showed by immunostaining that the expression of iNOS was suppressed by inhalation of N(G)-nitro-L-arginine methyl ester in mice with Candida-induced ALI. This study tested the hypothesis that a novel iNOS inhibitor suppresses not only iNOS expression, but also iNOS messenger RNA (mRNA) production by interrupting a positive feedback loop at the time of NO production in Candida-induced ALI. Mice were pretreated by inhalation of saline or ONO-1714, a selective iNOS inhibitor, and were given an intravenous injection of Candida albicans to induce ALI. After inhalation of 1 mM aerosolized ONO-1714, the nitrite-nitrate concentration in bronchoalveolar lavage fluid (BALF) at 24 h was significantly lower than that after inhalation of saline. Tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) levels and neutrophils in BALF were decreased by inhalation of ONO-1714. Inhalation of ONO-1714 markedly suppressed nitrotyrosine production and inhibited the expression of iNOS mRNA as well as proteins in the lung. Survival was prolonged by inhalation of ONO-1714. We conclude that pretreatment with inhaled ONO-1714 suppresses the production of peroxinitrite and decreases oxidative stress associated with peroxinitrite in Candida-induced ALI.
