Abstract
It is unclear whether molnupiravir has a beneficial effect on vaccinated patients infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We here evaluated the efficacy of molnupiravir in patients with mild-to-moderate coronavirus disease 2019 (COVID-19) during the Omicron variant surge in Fukushima Prefecture, Japan. We enrolled patients with mild-to-moderate COVID-19 who were admitted to hospitals between January and April, 2022. Clinical deterioration after admission was compared between molnupiravir users (n = 230) and non-users (n = 690) after 1:3 propensity score matching. Additionally, we performed forward stepwise multivariate logistic regression analysis to evaluate the association between clinical deterioration after admission and molnupiravir treatment in the 1:3 propensity score-matched subjects. The characteristics of participants in both groups were balanced as indicated by covariates with a standardized mean difference of < 0.1. Regarding comorbidities, there was no imbalance between the two groups, except for the presence of hypertension, dyslipidemia, diabetes mellitus, and cardiac disease. The clinical deterioration rate was significantly lower in the molnupiravir users compared to the non-users (3.90% vs 8.40%; P = 0.034). Multivariate logistic regression analysis demonstrated that receiving molnupiravir was a factor for preventing deterioration (odds ratio 0.448; 95% confidence interval 0.206-0.973; P = 0.042), independent of other covariates. This real-world study demonstrates that molnupiravir contributes to the prevention of deterioration in COVID-19 patients after hospitalization during the Omicron variant phase.

Abstract
BACKGROUND During the fifth wave of the coronavirus disease 2019 (COVID-19) pandemic in Japan, which took place between June and September 2021, a significant number of COVID-19 cases with deterioration occurred in unvaccinated individuals < 65 years old. However, the risk factors for COVID-19 deterioration in this specific population have not yet been determined. This study developed a prediction method to identify COVID-19 patients < 65 years old who are at a high risk of deterioration. METHODS This retrospective study analyzed data from 1,675 patients < 65 years old who were admitted to acute care institutions in Fukushima with mild-to-moderate-1 COVID-19 based on the Japanese disease severity criteria prior to the fifth wave. For validation, 324 similar patients were enrolled from 3 hospitals in Yamagata. Logistic regression analyses using cluster-robust variance estimation were used to determine predictors of disease deterioration, followed by creation of risk prediction scores. Disease deterioration was defined as the initiation of medication for COVID-19, oxygen inhalation, or mechanical ventilation starting one day or later after admission. RESULTS The patients whose condition deteriorated (8.6%) tended to be older, male, have histories of smoking, and have high body temperatures, low oxygen saturation values, and comorbidities, such as diabetes/obesity and hypertension. Stepwise variable selection using logistic regression to predict COVID-19 deterioration retained comorbidities of diabetes/obesity (DO), age (A), body temperature (T), and oxygen saturation (S). Two predictive scores were created based on the optimism-corrected regression coefficients: the DOATS score, including all of the above risk factors, and the DOAT score, which was the DOATS score without oxygen saturation. In the original cohort, the areas under the receiver operating characteristic curve (AUROCs) of the DOATS and DOAT scores were 0.81 (95% confidence interval [CI] 0.77-0.85) and 0.80 (95% CI 0.76-0.84), respectively. In the validation cohort, the AUROCs for each score were both 0.76 (95% CI 0.69-0.83), and the calibration slopes were both 0.80. A decision curve analysis confirmed the clinical practicability of both scores in the validation cohort. CONCLUSIONS We established two prediction scores that can quickly evaluate the risk of COVID-19 deterioration in mild/moderate patients < 65 years old.

Abstract
Background: Mutations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may reduce the efficacy of neutralizing monoclonal antibody therapy against coronavirus disease 2019 (COVID-19). We here evaluated the efficacy of casirivimab-imdevimab in patients with mild-to-moderate COVID-19 during the Delta variant surge in Fukushima Prefecture, Japan. Methods: We enrolled 949 patients with mild-to-moderate COVID-19 who were admitted to hospital between July 24, 2021 and September 30, 2021. Clinical deterioration after admission was compared between casirivimab-imdevimab users (n = 314) and non-users (n = 635). Results: The casirivimab-imdevimab users were older (P < 0.0001), had higher body temperature (≥ 38°C) (P < 0.0001) and greater rates of history of cigarette smoking (P = 0.0068), hypertension (P = 0.0004), obesity (P < 0.0001), and dyslipidemia (P < 0.0001) than the non-users. Multivariate logistic regression analysis demonstrated that receiving casirivimab-imdevimab was an independent factor for preventing deterioration (odds ratio 0.448; 95% confidence interval 0.263-0.763; P = 0.0023). Furthermore, in 222 patients who were selected from each group after matching on the propensity score, deterioration was significantly lower among those receiving casirivimab-imdevimab compared to those not receiving casirivimab-imdevimab (7.66% vs 14.0%; p = 0.021). Conclusion: This real-world study demonstrates that casirivimab-imdevimab contributes to the prevention of deterioration in COVID-19 patients after hospitalization during a Delta variant surge.

Abstract
OBJECTIVES Delta-like 1 homolog (DLK1) is a non-canonical Notch ligand known to be expressed in several cancers but whose role in lung cancer is not yet fully understood. We sought to confirm DLK1 expression in small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC), and to examine DLK1's clinical significance. Furthermore, we examined the possible utility of DLK1 as a novel target in radioimmunotherapy (RIT). METHODS We retrospectively assessed the correlation between clinical features and DLK1 expression by immunohistochemistry in resected specimens from 112 patients with SCLC and 101 patients with NSCLC. Moreover, we performed cell and animal experiments, and examined the possibility of RIT targeting DLK1 in SCLC using iodine-125 (125I) -labeled anti-DLK1 antibody, knowing that 125I can be replaced with the alpha-particle-emitter astatine-211 (211At). RESULTS In SCLC and NSCLC, 20.5 % (23/112) and 16.8 % (17/101) of patients (respectively) had DLK1-positive tumors. In NSCLC, DLK1 expression was associated with recurrence-free survival (P < 0.01) but not with overall survival. In SCLC, there was no association between DLK1 expression and survival. In addition, 125I-labeled anti-DLK1 antibody specifically targeted DLK1 on human SCLC tumor cell lines. Furthermore, 125I-labeled anti-DLK1 antibody was incorporated into tumor tissue in a mouse model. CONCLUSION A proportion of SCLC and NSCLC exhibits DLK1 expression. As a clinical feature, DLK1 expression could be a promising prognostic factor for recurrence in patients with resected NSCLC. In addition, DLK1 could serve as a new therapeutic target, including RIT, as suggested by our pilot study using a radiolabeled anti-DLK1 antibody in SCLC.

Abstract
BACKGROUND Thymoma is known to cause autoimmune neuromuscular disease. However, anti-glutamate receptor antibody limbic encephalitis (LE) with thymoma is relatively rare. CASE PRESENTATION A 68-year-old woman was admitted with progressive memory impairment and personality change. Brain magnetic resonance imaging (MRI) revealed high intensity in the bilateral limbic areas on T2-weighted fluid-attenuation inversion recovery (FLAIR) images. Chest computed tomography revealed a mass in the anterior mediastinum. Surgical resection of the tumor, which was consistent with a type B3 thymoma, resulted in clinical improvement. After surgery, the cerebrospinal fluid (CSF) was found to be positive for anti-N-methyl-D-aspartate (NMDA) type glutamate receptor antibodies. These findings led to the diagnosis of paraneoplastic LE (PLE) associated with thymoma. CONCLUSION When a patient presents with neurologic symptoms of unknown origin, the possibility of LE accompanied by thymoma should be considered. Rapid treatment is desirable before the symptoms become irreversible.

Abstract
The present retrospective multi-center study aimed to evaluate the efficacy and feasibility of nanoparticle albumin-bound (nab)-paclitaxel plus carboplatin as a second or late-phase chemotherapy in patients with non-small cell lung cancer (NSCLC). A total of 25 patients with recurrent or advanced NSCLC who had received previous chemotherapy were treated with nab-paclitaxel (70-100 mg/m2, intravenously) on days 1, 8 and 15 every 28 days with a carboplatin area under the concentration-time curve of 4-6 on day 1. The overall response rate, disease control rate, progression-free survival (PFS), overall survival (OS) and toxicities were statistically evaluated. Of the 25 patients, there were 9 cases of recurrent disease following surgery, 16 cases of advanced disease, 13 cases of adenocarcinoma, 11 cases of squamous cell carcinoma and 1 case of large cell carcinoma. A total of 13 patients received second-line chemotherapy and 12 received fourth-line or later chemotherapy. One patient exhibited a complete response, 7 had a partial response, 10 exhibited stable disease and 7 had progressive disease. The overall response rate was 32.0% and the disease control rate was 72.0%. The median PFS and median OS following nab-paclitaxel treatment were 4.0 and 14.0 months, respectively. Frequent treatment-associated adverse events were myelosuppression, peripheral neuropathy, gastrointestinal symptoms and baldness, the majority of which were grade 1-2. Grade 3-4 neutropenia, thrombocytopenia and anemia occurred in 7 (28.0%), 3 (12.0%) and 2 (8.0%) patients, respectively. No patients experienced grade 3-4 sensory neuropathy and no grade 5 adverse effects were observed. Nab-paclitaxel plus carboplatin as second-phase or later chemotherapy provided a small but significant survival benefit for patients with recurrent or advanced NSCLC, with tolerable adverse effects. To the best of our knowledge, the results of the present study demonstrated for the first time that nab-paclitaxel plus carboplatin is a promising and feasible late-phase chemotherapeutic agent for NSCLC.

Abstract
Intrapulmonary solitary fibrous tumor (SFT) of the pleura; the so-called inverted pattern, which appears to grow into the lung parenchyma, is extremely rare. We experienced a 66-year-old woman with an intrapulmonary SFT that recurred locally with malignant transformation 2 years after wedge resection of the left upper lobe for the primary tumor. Subsequently, she underwent a lobectomy of the residual left upper lobe. Six years after the second operation she was well, without rerecurrence. Complete excision and long-term follow-up of intrapulmonary SFTs of the pleura are important, even when the primary tumor displays benign histopathologic features.

Abstract
Background Video-assisted thoracic surgery (VATS) lobectomy is a standard treatment for lung cancer. This study retrospectively compared long-term outcomes after VATS lobectomy versus lobectomy via open thoracotomy for clinical stage IA non-small cell lung cancer (NSCLC). Methods From July 2002 to June 2012, 160 patients were diagnosed with clinical stage IA NSCLC and underwent lobectomy. Of these, 114 underwent VATS lobectomy and 46 underwent lobectomy via open thoracotomy. Results The 5-year disease-free survival (DFS) rate was 88.0% in the VATS group and 77.1% in the thoracotomy group for clinical stage IA NSCLC (p = 0.1504), and 91.5% in the VATS group and 93.8% in the thoracotomy group for pathological stage IA NSCLC (p = 0.2662). The 5-year overall survival (OS) rate was 94.1% in the VATS group and 81.8% in the thoracotomy group for clinical stage IA NSCLC (p = 0.0268), and 94.8% in the VATS group and 96.2% in the thoracotomy group for pathological stage IA NSCLC (p = 0.5545). The rate of accurate preoperative staging was 71.9% in the VATS group and 56.5% in the thoracotomy group (p = 0.2611). Inconsistencies between the clinical and pathological stages were mainly related to tumor size, nodal status, and pleural invasion. Local recurrence occurred for one lesion in the VATS group and six lesions (five patients) in the thoracotomy group (p = 0.0495). Conclusions The DFS and OS were not inferior after VATS compared with thoracotomy. Local control was significantly better after VATS than after thoracotomy. Preoperative staging lacked sufficient accuracy.

Abstract
A 40-year-old female patient underwent surgery at our hospital for recurrent pneumothorax. A defect on the right diaphragm was diagnosed as ectopic endometriosis. However, air leakage continued 2 days after surgery. Chest computed tomography identified a 5-mm ground glass opacity in the right S3 field, suggestive of lung cancer. Ten days after the initial surgery, she underwent curative surgery for both pneumothorax and the lung tumor. The tumor was diagnosed as bronchioloalveolar carcinoma, but no other endometriosis was identified. The patient has remained well with no recurrence of lung cancer or pneumothorax since the second surgery.

Abstract
The conditions in which degradation processes at the positive electrode/electrolyte interface occur are still incompletely understood and traditional surface analytical techniques struggle to characterize and depict accurately interfacial films. In the present work, information on the growth and evolution of the interphases upon storage and cycling as well as their electrochemical consequences are gathered in the case of LiNi(1/2)Mn(1/2)O(2) with commonly used LiPF(6) (1M in EC/DMC) electrolyte. The use of (7)Li, (19)F and (31)P MAS NMR, made quantitative through the implementation of empirical calibration, is combined with transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) to probe the elements involved in surface species and to unravel the inhomogenous architecture of the interphase. At room temperature, contact with the electrolyte leads to a covering of the oxide surface first by LiF and lithiated organic species are found on the outer part of the interphase. At 55°C, not only the interphase proceeds in further covering of the surface but also thickens resulting in an increase of 240% of lithiated species and the presence of -POF(2) fluorophosphates. The composition gradient within the interphase depth is also strongly affected by the temperature. In agreement with the electrochemical performance, quantitative NMR surface analyses show that the use of LiBOB-modified electrolyte results in a Li-enriched interphase, intrinsically less resistive than the standard LiPF(6)-based interphase, comprised of a mixture of resistive LiF with non lithiated species.

Abstract
Neoclassical toroidal viscosities (NTVs) in tokamaks are investigated using a δf Monte Carlo simulation, and are successfully verified with a combined analytic theory over a wide range of collisionality. A Monte Carlo simulation has been required in the study of NTV since the complexities in guiding-center orbits of particles and their collisions cannot be fully investigated by any means of analytic theories alone. Results yielded the details of the complex NTV dependency on particle precessions and collisions, which were predicted roughly in a combined analytic theory. Both numerical and analytic methods can be utilized and extended based on these successful verifications.

Abstract
Secretoglobin (SCGB) 3A2 is a downstream target gene for the thyroid transcription factor-1 (TITF1). SCGB3A2 plays a role as an anti-inflammatory agent, however, its role in primary pulmonary carcinomas has not been examined. We assessed immunohistochemical expression of SCGB3A2 in primary pulmonary carcinomas and evaluated the correlation between the expression and histopathological phenotypes and prognosis. One hundred and fifty-six primary lung cancers undergone for surgical resection were examined. The percentages of SCGB3A2 positive cells were scored and tumors had immunoreactivity in more than 10% of tumor cells were considered positive for SCGB3A2. Overall reactivity for SCGB3A2 was observed in 116 (74.4%) of 156 primary lung cancers. SCGB3A2 was predominantly expressed in adenocarcinomas (86.5%), compared with squamous cell carcinomas (50.0%) and small cell carcinomas (42.9%). The expression in papillary adenocarcinomas was seen at higher frequency than that in tubular adenocarcinomas. There was no significant relationship between SCGB3A2 expression and tumor differentiation, and pathological stage. Positive expression of SCGB3A2 was not associated with better survival rate. SCGB3A2 expression in primary pulmonary carcinomas is high, especially in adenocarcinomas. Our results indicate that SCGB3A2 has a potential to be a specific and useful marker for primary pulmonary adenocarcinomas.

Abstract
Inferior laryngeal nerve (ILN), which usually arises from vagus nerve, runs recurrent course and is called recurrent ILN (RILN). Intimate knowledge of normal and anatomic variants of the ILN reduces the risk of nerve injury and vocal cord paralysis in thyroid and parathyroid surgery. The nonrecurrent ILN (NRILN) is a rare nerve anomaly that is associated with a right aberrant subclavian artery. We encountered 2 patients with NRILN during thyroid surgery. Patient 1, a 57-year-old woman, had mediastinal thyroid tumor without vascular anomaly. Patient 2, a 47-year-old woman with a history of esophageal foreign body (fish bone), was suspected to have NRILN with vascular anomaly before surgery, as judged by preoperative enhanced CT. In the patient 1, we verified laryngeal mobility function of the NRILN by nerve stimulation, and confirmed the absence of RILN in usual recurrent course. The findings in the patient 1 indicate that NRILN without subclavian artery anomaly is a genuine entity. In both patients we performed thyroid surgery safely and fast by expectation and identification of NRILN by use of nerve stimulator. In conclusion, we confirm the existence of NRILN without vascular anomaly and show effectiveness of preoperative enhanced CT and valuable use of nerve stimulator for nerve preservation in the patients with NRILN.

Abstract
UNLABELLED Bone marrow (BM) cells are considered the source of stem cells for various organs. However, how quickly BM cells can penetrate and constitute lymphoid organs remains elusive. In the present study, we addressed this issue in a model using genetically-labeled syngeneic BM transplantation (BMT). METHODS Donor BM cells were obtained from "green mice", transgenic mice with enhanced GFP. Lethally irradiated C57BL/6 mice were infused with 1 x 10(6) BM cells from the green mice through the tail vein. BM chimerism was analyzed by FACS and the presence of donor BM cells in thoracoabdominal organs was assessed by fluorescence microscopy. The commitment of BM cells was examined by immunohistochemical staining using epithelium-, macrophage-, B and T-lymphocyte, and endothelium-specific antibodies. RESULTS BM chimerism reached 40+/- 18.5%, 82.6 +/- 23.4%, and 72 +/- 18% (mean +/- SD) at 1, 4, and 12 wks after BMT, respectively. GFP-positive cells were detected in all organs in the course of chimeric formation. Most GFP-positive cells were T and B lymphocytes in lymphoid systems including spleen, thymus, mesenteric lymph nodes and microvilli, and some were positive for macrophage and endothelial cell markers. CONCLUSIONS Our results indicate that BM-derived cells migrate rapidly into various thoracoabdominal organs after BMT, and that lymphoid tissues are predominantly replaced with infused BM in lethally-irradiated mice. This confirmed the previous finding by others and suggests high interest of this model for further studies to characterize kinetics and roles of infused cells.

Abstract
AIMS/HYPOTHESIS Ectopic activation of hedgehog (HH) signalling in pancreas induces various abnormal morphogenetic events in the pancreas. This study analysed the dose-dependent requirement of patched homologue 1 (PTCH1), a negative regulator of HH signalling on pancreatic development. METHODS We used a recessive spontaneous mutant mouse denoted as mes which carries a mutated Ptch1 resulting in deletion of the most carboxy-terminal cytoplasmic domain of the PTCH1 protein. In this study, we analysed pancreatic morphology in Ptch1 ( +/+ ), Ptch1 ( +/mes ), Ptch1 (+/-), Ptch1 ( mes/me ) (s) and Ptch1 (-/mes ) mouse embryos, as well as the islet mass in adult Ptch1 (+/+), Ptch1 (+/mes ) and Ptch1 (+/-) mice. RESULTS Until embryonic day (E) 12.5, no obvious abnormality of pancreas was observed in any of the Ptch1 mutants. The levels of PDX1 and glucagon were also not evidently different among the mice genotypes studied. Thereafter, morphological abnormalities appeared in the Ptch1 mutant mice. The beta, alpha and exocrine cell masses decreased at E18.5 in parallel with increased HH signalling, with beta cell mass showing the highest sensitivity to HH signalling with a significant decrease even in Ptch1 (+/mes ) mice. Adult Ptch1 (+/-) mice also showed a significant decrease in beta cell mass compared with wild-type mice. CONCLUSIONS/INTERPRETATION Our findings indicate that the carboxy-terminal domain of Ptch1 is essential for pancreatic development. In addition, the loss of Ptch1 function decreases both the endocrine and exocrine cell mass in a dose-dependent manner, with beta cells particularly sensitive to changes in HH signalling.

Abstract
Carbohydrates antigens in cancer cells are considered to be important molecules, which may play a critical role for metastasis. To elucidate the prognostic relevance of the expression of peanut agglutinin (PNA) binding carbohydrates in patients with lung adenocarcinoma, we investigated the PNA binding carbohydrates immunohistochemically in both of primary tumors and involving nodal lesions. A total of 62 patients with node-positive primary lung adenocarcinoma, who had undergone complete resection and regional nodes dissection were subjected to this study. There were no significant correlations between PNA staining rates and clinicopathological variables. The survival rate of patients who had positive PNA staining in both of primary tumor and nodal lesion was significantly higher than those of patients in the other groups. Furthermore, the loss of the staining rate of PNA was an independent prognostic factor beside the lymphatic vessel invasion using multivariate analysis. The expression of PNA binding carbohydrates in tumor tissue and nodal lesion would be a novel significant prognostic factor for patients with node-positive lung adenocarcinomas.

Abstract
PURPOSE Peanut agglutinin (PNA) recognizes tumor-associated carbohydrates. In this study, we aimed to identify the core protein harboring PNA-binding sugars in the human lung and to explore the relationship with the pathology of primary non-small cell lung cancers (NSCLC). EXPERIMENTAL DESIGN PNA lectin blotting was used to detect PNA-binding proteins in the microsomal fraction of lung tissue from 24 patients with NSCLC. The 55- to 65-kDa core peptide PNA-binding protein was characterized by enzymatic treatment and identified by immunoprecipitation and affinity chromatography. The expression level and increase in size of the 55- to 65-kDa PNA-binding protein/decay-accelerating factor (DAF) were compared between normal and tumor regions of the tumor tissue by Western blotting and quantitative PCR. RESULTS The 55- to 65-kDa PNA-binding protein was observed in human lung. This was a glycosylphosphatidylinositol-anchored membrane protein carrying O-linked carbohydrates. This core protein was identified as DAF, one of the complementary regulatory proteins. DAF was enlarged to 65 to 75 kDa in NSCLC tumor lesions due to sialylation in the sugar moiety. At the transcription level, DAF levels were significantly lower in tumor regions, suggesting its down-regulation in NSCLC cells. CONCLUSIONS DAF was identified as a new PNA-binding protein in the human lung. The down-regulation and heavy sialylation of DAF was associated with pathology in NSCLC, and these alterations make this protein a potential marker for NSCLC.

Abstract
Decay-accelerating factor (DAF) is one of the complement regulatory proteins. Two isoforms of DAF have been identified in humans. In this study, we isolated novel cDNAs encoding five isoforms of DAF from the human lung, which were generated by insertion of new exonic sequences. RT-PCR revealed that all isoforms were expressed in almost all tissues tested, although the expression patterns and levels differed among the tissues. Transfection of isoform vDAF1, 2, and 3 cDNAs into CHO cells showed that these molecules are soluble forms secreted after glycosylation. Isoform vDAF4 and vDAF5 cDNAs included a part of and the entire intron 7 sequence, respectively, and the transfection of vDAF4 cDNA produced a large, glycosylated, membrane-bound form. These results suggest that more than seven isoforms of human DAF are involved in the regulation of complement activation under physiological conditions through their specific structures and localization.

Abstract
Prognostic value of p53 protein expression in node-negative lung adenocarcinoma is still controversy. The expression of p53 protein was examined immunohistochemically in lung adenocarcinoma using monoclonal antibody BP53-12. A total 131 cases of primary lung adenocarcinoma were examined. Relationship between expression of p53 protein and clinicopathologic factors were studied. Overexpression of p53 protein was found in 19 patients (14.5%). Univariate and multivariate analysis showed that overexpression of p53 protein was an independent prognostic factor in node-negative lung adenocarcinoma. p53 alteration could be a valuable predictor for prognosis in node-negative lung adenocarcinoma.

Abstract
Dimensionality is one of the most important parameters of physical phenomena. Only two things determine the universality class of a phase transition: the dimensionality of a given system and the symmetry of the order parameter. In most cases, the dimensionality of a substance is predetermined by its crystal structure. Examples in which the effective dimensionality is reduced are quite rare. Here we show that the three-dimensional cubic system of Tl(2)Ru(2)O(7) most probably evolves into a one-dimensional spin-one Haldane system with a spin gap below 120 K, accompanied by anomalies in the structure, resistivity and susceptibility. We argue that these anomalies are due to an orbital ordering of Ru 4d electrons, with a strong coupling among three degrees of freedom: orbital, spin and lattice. Our work provides a unique example of the spontaneous formation of Haldane system with an insight into the intriguing interplay of different degrees of freedom.

Abstract
OBJECTIVE A key enzyme of fatty acid synthesis, fatty acid synthase (FAS), is expressed in human cancers, including squamous-cell carcinoma of the lung, and long-chain fatty acids are intracellularly transported and/or taken up from blood by fatty-acid-binding proteins (FABPs). Since the liver-type (L-) FABP, a member of the FABPs, is detected in a subset of gastric adenocarcinomas, the expression of FAS, L-FABP and vascular endothelial growth factor (VEGF) was investigated in human lung carcinomas to elucidate the mechanisms of production and transportation of fatty acid(s) in cancer. METHODS Expression of L-FABP, FAS and VEGF in 199 surgically resected lung carcinomas was examined immunohistochemically. Possible associations of the expression of each protein with major clinicopathological factors were analyzed. RESULTS L-FABP was detected in 60% (120 of 199) of the lung carcinoma cases; detection was increased in large-cell carcinoma (80%) and adenosquamous carcinoma (83%), but low in squamous-cell carcinoma (47%) and in small-cell carcinoma (57%). Overall expression of FAS was 67.3% (134 of 199 cases) and that of VEGF was 86.8% (158 of 199 cases), respectively. Expression of L-FABP was not correlated with the FAS status, but there was a tendency to co-expression of L-FABP and VEGF. There was no association between L-FABP, FAS or VEGF expression and clinicopathological data. CONCLUSIONS L-FABP, FAS and VEGF are highly expressed in human lung cancer, and expression of L-FABP is associated with that of VEGF but not that of FAS, suggesting that L-FABP might be involved in the uptake of fatty acid(s) from the bloodstream.

Abstract
The present study was designed to determine the extent of lymph node dissection for clinical T1 non-small cell lung cancer without negatively influencing curability. The study included 192 cases with clinical T1 non-small cell lung cancers who underwent lobectomy with mediastinal lymphadenectomy. Among 69 cases with right upper lobe tumors, metastasis was found in subcarinal lymph node in one case only. No metastasis was found in subcarinal node in cases free of metastasis in hilar and/or superior mediastinal nodes. Among 33 cases with right lower lobe tumors, metastasis was detected in the superior mediastinal node only in cases with metastasis in hilar and/or subcarinal nodes. Among 51 cases with left upper lobe tumors, no metastasis was found in the subcarinal node. Among 22 cases with left lower lobe tumors, metastasis was found in the superior mediastinal nodes only in cases with metastasis in hilar and/or subcarinal nodes. We propose the following scheme for the extent of mediastinal node dissection. Dissection of mediastinal node for clinical T1 non-small cell lung cancer cannot be omitted. But, 1) for upper lobe tumors, subcarinal lymphadenectomy could be omitted if no metastasis is found in hilar and superior mediastinal nodes based on gross and microscopic examination of frozen sections. 2) Similarly, for lower lobe tumors, superior mediastinal lymphadenectomy could be omitted if no metastasis is detected in the hilar and subcarinal nodes.

Abstract
A 36-year-old woman complained of cough and high fever. Computed tomographic scans demonstrated a mediastinal mass. A couple of months later, she developed dryness in her eyes and mouth. Biopsy of the lip confirmed the diagnosis of Sjögren's syndrome. She underwent thymo-thymomectomy. Pathological findings of the mass revealed thymoma. At two months after surgery, she developed ptosis and dysphagia that were compatible with myasthenia gravis. The clinical symptoms were adequately controlled with prednisolone. At eleven months after surgery, she presented with severe anemia, which led to the diagnosis of pure red cell aplasia. The following treatment with cyclosporin caused hemoglobin concentration to rise. However, she continues to suffer from dryness of her eyes and mouth. The case is the first to be reported with Sjögren's syndrome and the triad of thymoma, myasthenia gravis and pure red cell aplasia, and is compared with previously reported cases of the three conditions.

Abstract
OBJECTIVE A prospective randomized trial was performed to investigate the prognostic advantage of postoperative adjuvant chemotherapy in patients with resected stage I-II non-small cell lung cancer (NSCLC). PATIENTS AND METHODS From March 1992 to December 1994, 221 patients with completely resected stage I-II primary NSCLC were enrolled and randomly assigned to two groups, as follows: 2-year oral administration of Uracil plus Tegafur (UFT) (adjuvant group, 109 patients), and surgical treatment alone (control group, 110 patients). RESULTS The overall 5-year survival rates were 79% for the adjuvant group and 75% for the control group, and there was no statistical significance. The 5-year disease-free survival rates were 78% for the adjuvant group and 71% for the control group, and there was also no statistical significance. There have been seen no severe complications in the adjuvant group. The mean total dosages of UFT were about 75% of maximum basic amount. CONCLUSIONS The UFT regimen was feasible. However, we have not observed any survival benefit in the adjuvant group. Larger trials are needed to confirm the effect of UFT to patients with resected NSCLC.

Abstract
OBJECTIVE We evaluated preoperative pulmonary function as a predictor of respiratory complications and mortality in patients undergoing lung cancer resection to confirm the guideline of the British Thoracic Society: lung cancer surgery in patients with predictive postoperative FEV(1.0) (%FEV(1.0)ppo) > 40% and predictive postoperative diffusion capacity for carbon monoxide (%DL(co)ppo) > 40% can be carried out with average risk. METHODS We retrospectively studied 356 consecutive patients who underwent pulmonary resection at our Department from January 1992 to December 2001. Preoperative pulmonary function tests included vital capacity (VC), %VC, forced expiratory volume in one second (FEV(1.0)), FEV(1.0)%, diffusion capacity for carbon monoxide (DL(co)), predictive postoperative FEV(1.0) (FEV(1.0)ppo), postoperative respiratory function expressed as a percentage of the predicted normal value (%FEV(1.0) ppo, %DL(co)ppo). Postoperative complications were divided into 2 groups: respiratory complications (pneumonia, atelectasis, etc) and other complications (bronchopleural fistula, prolonged air leak, arrhythmia, etc). RESULTS Postoperative deaths occurred in 14 (3.9%) patients. Postoperative respiratory complications developed in 27 (7.6%) patients. Pneumonectomy (p < 0.001), preoperative chemotherapy (p < 0.01) and advanced stage (p < 0.05) were identified as risk factors of postoperative deaths. Patients undergoing lobectomy with FEV(1.0) > or = 1,500 ml did not die of respiratory complications. Patients undergoing pneumonectomy with FEV(1.0)ppo > or = 800ml/m2 did not die of respiratory complications. Patients undergoing pneumonectomy with %FEV(1.0)ppo < 40% and %DL(co)ppo < 40% did not survive. Five of the 7 patients who died of respiratory complications were treated with preoperative chemotherapy. The values of their %DL(co)ppo were all less than 40%. By multivariate analysis, %FEV(1.0)ppo was significant independent factor associated postoperative death. CONCLUSIONS We conclude that the guideline is useful for the selection for surgery of lung cancer patients. If preoperative chemotherapy is performed, the measurement of %DL(co) is recommended before surgery.

Abstract
The expression of 15 kinds of lectin-binding carbohydrates was examined histochemically in lung adenocarcinoma. The relation between expression of lectin binding carbohydrates and clinicopathologic factors was studied. The expression of peanut agglutinin (PNA) binding carbohydrates showed a high lymph node metastatic rate. Relation between PNA-binding carbohydrate expression and lymphatic vessel invasion was also recognized. Multivariate analysis showed that PNA-binding carbohydrate expression was an independent predictive factor of lymph node metastasis (odds ratio: 2.8) and of lymphatic vessel invasion (odds ratio: 5.2). The expression of PNA-binding carbohydrates would be a significant predictive factor for lymph node metastasis of lung adenocarcinomas.

Abstract
We report a 15-year-old boy with bilateral chylothorax complicating Gorham's syndrome. Thoracic duct ligation failed to prevent fluid reaccumulation. The patient died of lymphocytopenia. Autopsy revealed vascular proliferation in the parietal and visceral pleura as well as in the ribs, which seemed to cause persistent chylothorax responsible for the poor prognosis of this patient. We reviewed treatments provided to 22 patients reported in the literature with Gorham's syndrome and chylothorax.

Abstract
We report two cases of a bronchopleural fistula with, and without, empyema treated by endoscopic submucosal injection of polidocanol (sclerotherapy) and application of cyanoacrylate. Case 1: A 60-year-old man underwent left pleuropneumonectomy for lung cancer. He developed bronchopleural fistula with empyema at 32 days after the operation. We performed sclerotherapy around the fistula. The air leakage stopped at 2 weeks after the sclerotherapy, and the fistula was closed. He was eventually cured of the empyema by pleural drainage. Case 2: A 61-year-old man underwent left pneumonectomy for lung cancer. He developed bronchopleural fistula without empyema at 50 days after the operation. We performed sclerotherapy and application of cyanoacrylate. After this therapy, the air leakage stopped immediately, and the bronchopleural fistula was closed. The sclerotherapy and application of cyanoacrylate are not only technically easy, but also very effective for treatment of bronchopleural fistula. Sclerotherapy and cyanoacrylate may be advocated as a first therapeutic step.

Abstract
Musashi1 is an RNA-binding protein abundantly expressed in the developing mouse central nervous system. Its restricted expression in neural precursor cells suggests that it is involved in the regulation of asymmetric cell division. Musashi1 contains two ribonucleoprotein (RNP)-type RNA-binding domains (RBDs), RBD1 and RBD2. Our previous studies showed that RBD1 alone binds to RNA, while the binding of RBD2 is not detected under the same conditions. Joining of RBD2 to RBD1, however, increases the affinity to greater than that of RBD1 alone, indicating that RBD2 contributes to RNA-binding. We have determined the three-dimensional solution structure of the C-terminal RBD (RBD2) of Musashi1 by NMR. It folds into a compact alpha beta structure comprising a four-stranded antiparallel beta-sheet packed against two alpha-helices, which is characteristic of RNP-type RBDs. Special structural features of RBD2 include a beta-bulge in beta2 and a shallow twist of the beta-sheet. The smaller 1H-15N nuclear Overhauser enhancement values for the residues of loop 3 between beta2 and beta3 suggest that this loop is flexible in the time-scale of nano- to picosecond order. The smaller 15N T2 values for the residues around the border between alpha2 and the following loop (loop 5) suggest this region undergoes conformational exchange in the milli- to microsecond time-scale. Chemical shift perturbation analysis indicated that RBD2 binds to an RNA oligomer obtained by in vitro selection under the conditions for NMR measurements, and thus the nature of the weak RNA-binding of RBD2 was successfully characterized by NMR, which is otherwise difficult to assess. Mainly the residues of the surface composed of the four-stranded beta-sheet, loops and C-terminal region are involved in the interaction. The appearance of side-chain NH proton resonances of arginine residues of loop 3 and imino proton resonances of RNA bases upon complex formation suggests the formation of intermolecular hydrogen bonds. The structural arrangement of the rings of the conserved aromatic residues of beta2 and beta3 is suitable for stacking interaction with RNA bases, known to be one of the major protein-RNA interactions, but a survey of the perturbation data suggested that the stacking interaction is not ideally achieved in the complex, which may be related to the weaker RNA-binding of RBD2.

Abstract
mel-18 is a mammalian Polycomb group gene encoding a transcriptional repressor with tumor suppressive activity. Overexpression of mel-18 in mice results in cell cycle arrest of B cells upon B cell receptor stimulation with downregulation of c-myc. This phenotype is rescued in mel-18/c-myc double-transgenic mice, suggesting that c-myc locates downstream of mel-18. In mel-18 transgenic mice, the downregulation of cyclins D2 and E; CDK4, -6, and -7; and CDC25A causes the impairment in the activities of cyclin-dependent kinases, resulting in hypophosphorylation of the retinoblastoma protein. In contrast, the upregulation of c-Myc, CDC25, and CDC2/CDK2 kinase activities results in the augmentation of B cell proliferation in mel-18-deficient mice. We therefore propose that mel-18 negatively regulates the cell cycle through a c-myc/cdc25 cascade.

Abstract
Polycomb group (PcG) genes were initially described in Drosophila melanogaster as regulators of the homeobox gene. Four mammalian homologues, mel-18, bmi-1, M33 and rae-28, are analyzed in this study. They not only regulate mammalian homeotic genes by analogy with their Drosophila counterparts, but also have some influence on the growth and differentiation of B lymphocytes. Here we report that these four mammalian PcG genes are rapidly induced after antigen-receptor cross-linking in B cells. Thus we would like to propose that mammalian PcG genes can be categorized as a new type of immediate early gene.

Abstract
We attempted to construct the contour of recurrence in primary lung adenocarcinoma with clinicopathologic variables based on data of 131 patients with completely resected primary lung adenocarcinoma. In univariate analysis, tumor size (more or less 3 cm in diameter), p-T, p-N, pathological stage, differentiation, ly factor and v factor were chosen for prognostic predictors. In multivariate analysis, v factor and p-N were independent variables of local recurrence and metastatic recurrence, respectively. The examination of significant correlation among clinicopathologic variables in terms of 5-year survival rates of patients showed that tumor size, p-T, ly factor and v factor were profoundly related to local recurrence, whereas ly factor, differentiation and p-N were linked to distant metastasis. We therefore examined an additive effect of tumor size, differentiation and vascular invasion on recurrence. The results demonstrated that neither local nor metastatic recurrences were found in patients with well differentiated adenocarcinoma less than 3 cm in diameter if vascular invasion was negative. We conclude that vascular (ly factor and v factor) is central to lung adenocarcinoma recurrence. The vascular invasion is a powerful predictor of recurrence in less than 3 cm diameter, well differentiated adenocarcinoma of the lung.

Abstract
In order to confirm the linearization of permanent eruption, Masuyama's linearization method was applied to the data of Kitamura's study. At first, we considered the eruption age t alpha i of permanent teeth T alpha, where alpha corresponds a tooth of every description, and examined the linear regression of Y alpha i = log10 t alpha i on m(y) alpha (the mean of Y alpha i with respect to i), but the result was not good. For the correlation coefficient r between two variables in linear regression, the percentage of subjects with r > or = 0.970 was only 10.3% in males and 28.8% in females in Kitamura's study. Next we took notice of the eruption age u beta i of each tooth, which is the beta-th in order of eruption. The fitness of the linear regression of Z beta i = log10 u beta i on mz beta (the mean of Z beta i) was very good. The percentage of subjects with r > or = 0.970 increased to 80.0% in males and 86.0% in females. Then we used m(y) (beta) (rearranged m(y) alpha in order of increasing size) instead of mz beta as an independent variable in the linear regression. The degree of the linearization was slightly inferior to that using mz beta. In every linearization, a quasi-fixed point with coordinates (C, C) existed on the linearized dentition plot, where the value of C was almost equal in each way, i.e., C = 10.23 (years) for males and C = 8.91 (years) for females in Kitamura's data. This linearized dentition plot will be useful in detecting certain growth disturbances. The existence of a quasi-fixed point may be useful in forecasting the age of the eruption of subsequent teeth, once the first eruption is observed.

Abstract
A 55-year-old male with multiple endocrine neoplasia syndrome accompanied by hyperparathyroidism and hypergastrinemia was admitted because of local recurrence of thymic carcinoid tumor and a parathyroid adenoma. The recurrent thymic carcinoid tumor replaced anterior mediastinum, invaded brachiocephalic vein and superior vena cava, a disseminated nodule was found at pericardium. After induction chemotherapy using carboplatin and etoposide the operation was performed. The parathyroid tumor and recurrent thymic carcinoid tumor were removed completely together with brachiocephalic vein, superior vena cava, pericardium and anterior chest wall. Superior vena cava was replaced with synthetic graft and chest wall was reconstructed. The patient is alive and well 22 months after surgery without recurrence. Immunohistochemistry of removed specimens revealed parathormone and gastrin secreted from the parathyroid adenoma but not from the carcinoid tumor. Careful survey of systemic endocrine organs is necessary in case of thymic carcinoid tumor. Aggressive surgery in locally recurrent thymic carcinoid without distant metastasis must be considered.

Abstract
The majority of T lymphocytes start to develop at around day 15 of gestation (d15)-d17 in the thymus and comprise the peripheral repertoire characterized by the expression of polymorphic T-cell antigen receptors (TCRs). Contrary to these conventional T cells, a subset of T cells, called natural killer (NK) T cells (most of them expressing an invariant TCR encoded by the Valpha14Jalpha281 gene with a 1-nt N-region), preferentially differentiates extrathymically and dominates the peripheral T-cell population at a high frequency (5% in splenic T cells and 40% in bone marrow T cells). Here, we investigated the development of NK T cells and found that the invariant Valpha14+ TCR transcripts and the circular DNA created by Valpha14 and Jalpha281 gene rearrangements can be detected in the embryo body at d9.5 of gestation and in the yolk sac and the fetal liver at d11.5-d13.5 of gestation, but not in the thymus, whereas T cells with Valpha1+ TCR expression, a major population in the thymus, were not observed at these early stages of gestation. Fluorescence-activated cell sorter analysis also demonstrated that there exist CD3+ alpha beta+ T cells, almost all of which are Valpha14/Vbeta8+ NK+ T cells, during early embryogenesis. To our knowledge, this demonstrates for the first time that a T lymphocyte subset develops in extrathymic tissues during the early stages of embryogenesis.

Abstract
We previously isolated the mel-18 gene, a mammalian Polycomb group (PcG)-related gene with homology to bmi-1 oncogene. We show in this paper the existence of a new gene, mel-13, which overlapped with the mel-18 anti-oncogene. We discuss the relationships between mel-13 and the mel-18, bup, and Su(z)2 genes.
