Abstract
BACKGROUND AND OBJECTIVE The identification of factors associated with long-term prognosis after community-onset pneumonia in elderly patients should be considered when initiating advance care planning (ACP). We aimed to identify these factors and develop a prediction score model. METHODS Patients aged 65 years and older, who were hospitalized for pneumonia at nine collaborating institutions, were included. The prognosis of patients 180 days after the completion of antimicrobial treatment for pneumonia was prospectively collected. RESULTS The total number of analysable cases was 399, excluding 7 outliers and 42 cases with missing data or unknown prognosis. These cases were randomly divided in an 8:2 ratio for score development and testing. The median age was 82 years, and there were 68 (17%) deaths. A multivariate analysis showed that significant factors were performance status (PS) ≥2 (Odds ratio [OR], 11.78), hypoalbuminemia ≤2.5 g/dL (OR, 5.28) and dementia (OR, 3.15), while age and detection of antimicrobial-resistant bacteria were not associated with prognosis. A scoring model was then developed with PS ≥2, Alb ≤2.5, and dementia providing scores of 2, 1 and 1 each, respectively, for a total of 4. The area under the curve was 0.8504, and the sensitivity and specificity were 94.6% and 61.7% at the cutoff of 2, respectively. In the test cases, the sensitivity and specificity were 91.7% and 63.1%, respectively, at a cutoff value of 2. CONCLUSION Patients meeting this score should be considered near the end of life, and the initiation of ACP practices should be considered.

Abstract
BACKGROUND Current microbiological tests fail to identify the causative microorganism in more than half of all pneumonia cases. We explored biomarkers that could be used for differentiating between bacterial and viral pneumonia in patients with community-acquired pneumonia (CAP). METHODS In this prospective cohort study conducted in Japan, data obtained from adult patients with bacterial pneumonia, including bacterial and viral coinfections (bacterial pneumonia [BP] group), and purely viral pneumonia (VP group) at diagnosis were analyzed using multivariate logistic regression analysis to identify predictors of bacterial pneumonia. Furthermore, a decision tree was developed using the predictors. RESULTS A total of 210 patients were analyzed. The BP and VP groups comprised 108 and 18 patients, respectively. The other 84 patients had no identified causative microorganism. The two groups shared similar characteristics, including disease severity; however, a significant difference (p < 0.05) was observed between the two groups regarding sputum type; sputum volume score; neutrophil counts; and serum levels of interleukin (IL)-8, IL-10, and α1-antitrypsin (AAT). Sputum volume score (p < 0.001), IL-10 (p < 0.001), and AAT (p = 0.008) were ultimately identified as predictors of BP. The area under the curve for these three variables on the receiver operating characteristic (ROC) curve was 0.927 (95% confidence interval [CI]: 0.881-0.974). The ROC curve for sputum volume score and an AAT/IL-10 ratio showed a diagnostic cutoff of 1 + and 65, respectively. Logistic regression analysis using dichotomized variables at the cutoff values showed that the odds ratios for the diagnosis of BP were 10.4 (95% CI: 2.2-50.2) for sputum volume score (absence vs. presence) and 19.8 (95% CI: 4.7-83.2) for AAT/IL-10 ratio (< 65 vs. ≥ 65). CONCLUSIONS Considering that obtaining a definitive etiologic diagnosis with the current testing methods is difficult and time consuming, a decision tree with two predictors, namely sputum volume and the AAT/IL-10 ratio, can be useful in predicting BP among patients diagnosed with CAP and facilitating the appropriate use of antibiotics.

Abstract
BACKGROUND We conducted a multicenter study to evaluate the performance of a novel fully automated molecular point-of-care test using transcription-reverse transcription concerted reaction that can detect influenza A and B within 15 min in nasopharyngeal swabs and gargle samples (TRCsatFLU). METHODS Patients who visited or were hospitalized at eight clinics and hospitals with influenza-like illnesses between December 2019 and March 2020 participated in this study. We collected nasopharyngeal swabs from all patients and gargle samples from patients whom the physician judged fit to perform gargling. The result of TRCsatFLU was compared to a conventional reverse transcription-polymerase chain reaction (RT-PCR). If the results of TRCsatFLU and conventional RT-PCR were different, the samples were analyzed by sequencing. RESULTS We evaluated 233 nasopharyngeal swabs and 213 gargle samples from 244 patients. The average age of the patients was 39.3 ± 21.2. Of the patients, 68.9% visited a hospital within 24 h of symptom onset. The most common symptoms were fever (93.0%), fatigue (79.5%), and nasal discharge (64.8%). All patients in whom the gargle sample was not collected were children. Influenza A or B was detected in 98 and 99 patients in nasopharyngeal swabs and gargle samples using TRCsatFLU, respectively. Four and five patients in nasopharyngeal swabs and gargle samples, respectively, with different TRCsatFLU and conventional RT-PCR results. Influenza A or B was detected using sequencing in all samples with different results. Based on the combined conventional RT-PCR and sequencing results, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TRCsatFLU for influenza detection in nasopharyngeal swabs were 0.990, 1.000, 1.000, and 0.993, respectively. In the gargle samples, the sensitivity, specificity, PPV, and NPV of the TRCsatFLU for detecting influenza were 0.971, 1.000, 1.000, and 0.974, respectively. CONCLUSIONS The TRCsatFLU showed great sensitivity and specificity for the detection of influenza in nasopharyngeal swabs and gargle samples.

Abstract
AIMS Japanese cedar pollinosis (JCP) is a form of seasonal allergic rhinitis that affects 38.8% of the Japanese population. Particularly severe and most severe symptoms among JCP patients can lead to impairments of paid work productivity and unpaid work activities. Indeed, the current standard of care (SoC) is not always able to relieve these symptoms. Omalizumab, a novel JCP treatment recently approved in Japan, provides an effective add-on therapy to the SoC. This study estimates the effect of omalizumab on paid and unpaid work activities (i.e. its social impact) in patients with severe and most severe JCP symptoms in Japan. METHODS The impact of omalizumab was estimated through a one-year static cohort model using the Work Productivity and Activity Impairment Allergy Specific (WPAI-AS) questionnaire derived from a clinical trial on omalizumab enrolling patients with severe and most severe JCP symptoms, which had been conducted in Japan. This effect was quantified using Japanese official statistics on employment and time use. The human capital approach and the proxy good approach were employed to monetize paid and unpaid work activities, respectively. A sensitivity analysis was implemented to account for modeling structural uncertainties. RESULTS Our results show that the use of omalizumab might reduce the paid and unpaid work productivity losses due to severe and most severe JCP by nearly one-third. In the severe symptom period of three weeks, 36.6 million hours of lost paid and unpaid work hours could be avoided, which sums up to a monetized productivity loss of 728.3 million USD. CONCLUSIONS Omalizumab could provide substantial benefits in terms of paid and unpaid work activities in patients with severe and most severe JCP. Our results also highlight the importance of considering unpaid work in estimating productivity costs due to poor health.

Abstract
We evaluated a novel transcription-reverse transcription concerted reaction (TRC) assay that can detect influenza A and B within 15 min using nasopharyngeal swab and gargle samples obtained from patients with influenza-like illness, between January and March 2018 and between January and March 2019. Based on the combined RT-PCR and sequencing results, in the nasal swabs, the sensitivity and specificity of TRC for detecting influenza were calculated as 1.000 and 1.000, respectively. In the gargle samples, the sensitivity and specificity of TRC were 0.946 and 1.000, respectively. The TRC assay showed comparable performance to RT-PCR in the detection of influenza viruses.

Abstract
OBJECTIVES Emotion regulation processes, such as mindfulness, self-compassion, and acceptance, have been discussed as modifiable psychological factors related to middle-aged women's psychological distress and adjustment. Although these emotion regulation factors have been discussed separately, the question remains of which factors reflect the most variance in middle-aged women's health. Therefore, this study aimed to reveal the most relevant explanatory variable for middle-aged women's health: mindfulness, self-compassion, or acceptance. METHOD A total of 200 middle-aged women completed self-reported measures of depressive symptoms, menopausal symptoms, physical quality of life, mental quality of life, and well-being. RESULTS Correlation analysis showed that mindfulness, self-compassion, and acceptance were significantly associated with all variables of psychological distress and adjustment. Hierarchical multiple regression analysis revealed that acceptance significantly explained the most variance of depressive symptoms, menopausal symptoms, and mental quality of life. On the other hand, self-compassion significantly explained the greatest variance in well-being. CONCLUSIONS These findings suggest that, for middle-aged women, 'acceptance' is an important explanatory variable of psychological distress and 'self-compassion' is an important variable of psychological adjustment.

Abstract
Oral antibiotic therapy for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) usually involves an aminopenicillin with clavulanic acid, a macrolide, or a quinolone. To date, however, the clinical efficacy and safety of the oral cephalosporin cefditoren pivoxil has not been evaluated in Japanese patients with acute exacerbations of COPD. We conducted a prospective, multicenter, single arm, interventional study from January 2013 to March 2017 to determine the efficacy and safety of oral administration of 200 mg cefditoren pivoxil three times daily for 7 days in a cohort of 29 eligible patients from 15 hospitals. The mean age (SD) of participants was 73.1 (8.1) years and 28 had a smoking history (the mean [SD] of smoking index, 1426.7 [931.7]). The primary efficacy endpoint was clinical response (cure rate) at test of cure, which was set at 5-10 days after treatment ceased. Of the 23 patients finally analyzed, cure was achieved in 15 (65.2%), while 8 (34.8%) remained uncured. Previous experience of acute exacerbations significantly affected the cure rate: none of the three patients who had at least two prior exacerbations were cured, while 15 of the 20 patients with one or fewer prior exacerbations were cured (p = 0.032). The microbiological eradication rate was 88.9% at test of cure. During treatment, mild pneumonia was reported as an adverse event in one patient (3.4%) but resolved within 10 days of onset. We conclude that cefditoren pivoxil represents a viable alternative for antibiotic therapy in patients with few prior exacerbations.

Abstract
Although viruses are the major pathogen that causes upper respiratory tract infection (URTI) and acute bronchitis, antibiotics have been prescribed. This was a prospective observational study in influenza epidemics that enrolled adult outpatients who visited a hospital with respiratory tract infection symptoms. In this study, we evaluated the usefulness of FilmArray respiratory panel (RP). Fifty patients were enrolled. FilmArray RP detected the pathogens in 28 patients. The common pathogens were influenza virus (n = 14), respiratory syncytial virus (n = 6), and human rhinovirus (n = 6). Of the 14 patients with influenza virus, 6 were negative for the antigen test. The physicians diagnosed and treated the patients without the result of FilmArray in this study. Of the patients with positive FilmArray RP, 9 were treated with antibiotics; however, bacteria were detected in only 3 patients. By implementing FilmArray RP, URTI and acute bronchitis would be precisely diagnosed, and inappropriate use of antibiotics can be reduced.

Abstract
Background Prostaglandin D2 (PGD2) is primarily produced by mast cells and is contributing to the nasal symptoms including nasal obstruction and rhinorrhea. Objective This study aimed to evaluate the efficacy and safety of a novel PGD2 receptor 1 (DP1) antagonist, ONO‐4053, in patients with seasonal allergic rhinitis (SAR). Methods This study was a multicenter, randomized, double‐blind, parallel‐group study of patients with SAR. Following a one‐week period of placebo run‐in, patients who met the study criteria were randomized to either the ONO‐4053, leukotriene receptor antagonist pranlukast, or placebo group for a two‐week treatment period. A total of 200 patients were planned to be randomly assigned to receive ONO‐4053, pranlukast, or placebo in a 2:2:1 ratio. Nasal and eye symptoms were evaluated. Results Both ONO‐4053 and pranlukast had higher efficacy than placebo on all nasal and eye symptoms. ONO‐4053 outperformed pranlukast in a total of three nasal symptom scores (T3NSS) as well as in individual scores for sneezing, rhinorrhea, and nasal itching. For T3NSS, the Bayesian posterior probabilities that pranlukast was better than placebo and ONO‐4053 was better than pranlukast were 70.0% and 81.6%, respectively, suggesting that ONO‐4053 has a higher efficacy compared with pranlukast. There was no safety‐related issue in this study. Conclusions We demonstrated that the efficacy of ONO‐4053 was greater than that of pranlukast with a similar safety profile. This study indicates the potential of ONO‐4053 for use as a treatment for SAR (JapicCTI‐142706).

Abstract
A 62-year-old female patient with renal dysfunction and pulmonary adenocarcinoma developed postoperative recurrence and received carboplatin/pemetrexed and maintenance pemetrexed. As an anaplastic lymphoma kinase (ALK) gene translocation was identified, the therapy was changed to crizotinib. However, the patient’s blood creatinine level increased, and her physical status worsened. Alectinib also induced exacerbation of renal dysfunction but was controlled by dose reduction of 140 mg twice daily for 2 weeks treatment and 2 weeks break were repeated, and exhibited a partial response for 16 months. Here, we describe the case in which alectinib treatment had beneficial clinical effects on ALK-positive lung adenocarcinoma, which controlled the adverse renal effects by dose reduction and drug breaks.

Abstract
Background Various polymorphisms have been detected in the UDP‐glucuronosyltransferase 1A (UGT1A) gene, and UGT1A1*28 and UGT1A1*6 have important effects on the pharmacokinetics of irinotecan and the risk of severe toxicities during irinotecan therapy. This study was conducted to determine the maximum tolerated dose (MTD) of irinotecan chemotherapy according to the UGT1A1 genotype in previously treated lung cancer patients with the UGT1A1*28 or UGT1A1*6 polymorphism. Methods The eligibility criteria were as follows: lung cancer patients that had previously been treated with anticancer agents other than irinotecan, possessed the UGT1A1*28 or UGT1A1*6 polymorphism (group A included *28/*28, *6/*6, and *28/*6, and group B included *28/− and *6/−), were aged ≤75 years old, had a performance score of 0–1, and exhibited adequate bone marrow function. The patients were scheduled to receive irinotecan on days 1, 8, 15, 22, 29, and 36. Results Four patients were enrolled in this trial. Two patients were determined to be ineligible. The remaining two patients, who belonged to group B, received an initial irinotecan dose of 60 mg/m2, but did not complete the planned treatment because of diarrhea and leukopenia. Thus, in group B patients, 60 mg/m2 was considered to be the MTD of irinotecan. The study was terminated in group A because of poor case recruitment. Conclusions The MTD of irinotecan for previously treated lung cancer patients that are heterozygous for the UGT1A1*28 or UGT1A1*6 gene polymorphism is 60 mg/m2.

Abstract
Background Uridine 5′‐diphospho‐glucuronosyltransferase 1A1 (UGT1A1*27) is known to impair the effect of UGT in basic research; however, little clinical investigation has been conducted. To evaluate the effect of the UGT1A1*27 polymorphism in irinotecan therapy, we conducted a prospective study. Methods Eligibility criteria included: lung cancer patients; scheduled irinotecan therapy doses of single ≥ 80, combination ≥ 50, radiation with single ≥ 50, or radiation with combination ≥ 40 mg/m2; age ≥ 20; and Eastern Cooperative Oncology Group performance score (PS) 0–2. Patients were examined for UGT1A1*28 and *6 polymorphisms and received irinotecan. When the UGT1A1*28 polymorphism was detected, a search for UGT1A1*27 was conducted. Fifty patients were enrolled, with 48 patients determined eligible. Results UGT1A1 polymorphisms *28/*28, *6/*6, *28/*6, *28/−, *6/−, −/− observed 0 (0%), 1 (2%), 1 (2%), 7 (15%), 17 (35%) and 22 (46%), respectively. UGT1A1*27 were examined in nine patients including one ineligible patient; however, no polymorphisms were found. The study ceased after interim analysis. In an evaluation of the side effects of irinotecan, patients with UGT1A1*28 and UGT1A1*6 polymorphisms had a higher tendency to experience febrile neutropenia than wild type (25% and 32% vs. 14%). Incidences of grade 3/4 leukopenia and neutropenia were significantly higher in patients with UGT1A1*28 polymorphisms compared with wild type (75% vs. 32%, P = 0.049; 75% vs. 36%, P = 0.039, respectively). Conclusion Our prospective study did not locate the UGT1A1*27 polymorphism, suggesting that UGT1A1*27 does not significantly predict severe irinotecan toxicity in cancer patients.

Abstract
Primary mediastinal large B-cell lymphoma (PMLBCL) is one of the subtypes of diffuse large B-cell lymphoma. We experienced a rare case of PMLBCL that exhibited endobronchial involvement. A 33-year-old Japanese female with the chief complaints of epigastralgia, back pain, and nausea visited a primary care hospital. Computed tomography of the chest and abdomen demonstrated a bulky mass in the left anterior mediastinum, multiple pulmonary nodules, axillary lymph node swelling, and a pancreatic tumor. Fiberoptic bronchoscopy showed a white-tinged irregularly shaped endobronchial tumor accompanied by capillary vessel dilation in the left upper lobar bronchus. Taken together, these findings resulted in a diagnosis of PMLBCL.

Abstract
BACKGROUND AND OBJECTIVES Recent reports indicate that the incidence of nontuberculous mycobacterial-lung disease (NTM-LD) is increasing. This study aimed to investigate the epidemiology and clinical features of NTM-LD patients in Nagasaki prefecture, Japan to identify the negative prognostic factors for NTM-LD in Japan. METHODS The medical records of patients newly diagnosed with NTM-LD in eleven hospitals in Nagasaki prefecture between January 2001 and February 2010 were reviewed. Data regarding the annual population of each region and the incidence of all forms of tuberculosis were collected to assess geographic variations in NTM-LD incidence, isolates, and radiological features. RESULTS A total 975 patients were diagnosed with NTM-LD. The incidence increased over the study period and reached 11.0 and 10.1 per 100,000 population in 2008 and 2009, respectively. M. intracellulare was the most common pathogen in the southern region, and M. avium most common in other regions. The most common radiographic pattern was the nodular-bronchiectatic pattern. Age >60 years, body mass index <18.5 kg/m2, underlying lung disease, and cavitary pattern were the negative prognostic factors at the 1-year follow-up. CONCLUSIONS The incidence of NTM-LD has been increasing in Nagasaki prefecture. The isolates and radiographic features of patients vary markedly by region.

Abstract
Strontium chloride 89 (89Sr) is used as a systemic radiopharmaceutical therapy for the palliation of pain in patients with metastatic bone cancer. A 64-year-old man had previously undergone an operation to resect his right upper lobe of lung and sixth rib. He was diagnosed with lung cancer (large cell carcinoma, pT3N0M0, stage IIB). Three months later, he was treated with chemoradiotherapy for local recurrence. Ten months later, he could not sit up due to severe pain of the left ilium, although he had been treated with opiate analgesics. Fourteen months later, his hospital stay was prolonged and he was treated with 89Sr. One week after injection, the pain was almost completed relieved. Two weeks after injection, morphine infusion was stopped and a reduced dose of a fentanyl patch was used. He was also able to eat meals. Three weeks after injection, he started rehabilitation. Two months after the injection of 89Sr, he could return home from the hospital. Adverse events included grade 2 leukopenia, neutropenia and thrombocytopenia. These peaked 2 months after injection.

Abstract
Healthcare-associated pneumonia (HCAP) is a newly identified condition, and epidemiologic studies in Japan are still limited. We retrospectively observed patients with HCAP and community-acquired pneumonia (CAP) who were hospitalized between December 2004 and March 2005, and compared their disease characteristics. A total of 34 patients (14 with HCAP and 20 with CAP) were evaluated. Of the patients with HCAP, seven (50%) were hospitalized for at least 2 days in the preceding 90 days and five (35.7%) resided in a nursing home or extended care facility. Compared with patients with CAP, patients with HCAP were older, had more complications, including central nerve diseases, had greater disease severity, but lower serum albumin level. More methicillin-resistant Staphylococcus aureus, Pseudomonas spp., and anaerobes were isolated from patients with HCAP than from those with CAP. Conversely, more Streptococcus pneumoniae was detected and more penicillin was used in patients with CAP. This study provides additional evidence that HCAP should be distinguished from CAP and suggests the pathogenesis and therapeutic strategy for HCAP may be similar to those for hospital-acquired pneumonia.

Abstract
A 74-year-old man with poorly controlled diabetes mellitus was admitted to our hospital because of severe respiratory disturbance, fever, and sputum. We found massive consolidation of the right lung and nodular shadows on the left lung on chest X-ray, and detected influenza virus and Streptococcus pneumoniae antigen from a nasopharyngeal swab and urine sample, respectively. Co-infection with influenza virus and bacteria was suspected, and oseltamivir and biapenem were prescribed. Laboratory data improved after the addition of sivelestat sodium hydrate, an inhibitor of neutrophil-derived elastase; however, chest X-ray findings became worse on Day 8, and we administered 1 g methylprednisolone intravenously for two days. On Day 12, we detected Mycobacterium tuberculosis in the sputum, even though we did not previously detect any acid-fast bacilli, and started anti-tuberculosis drugs, such as isoniazid, rifampicin, ethambutol hydrochloride, and pyrazinamide; however, the patient died 12 days later. Severe influenza-related bacterial pneumonia with Streptococcus pneumoniae and subsequently secondary tuberculosis infection were finally suspected in this case. This was a very rare case in which additional tuberculosis infection was found in a patient with fulminant pneumonia due to co-infection of influenza virus and bacteria. It is necessary to observe patients with influenza carefully, especially when steroids are used, even if antibiotics are also administered.

Abstract
OBJECTIVE AND DESIGN Since rebamipide is effective for the treatment of ulcerative colitis (UC), we examined the involvement of hepatocyte growth factor (HGF) in the action of rebamipide. MATERIALS Fifty-five and forty female Balb/c mice, respectively, were used in Exp. 1 and 2. TREATMENT 50 mg/kg/day rebamipide (Exp. 1) and 1 x 10(7) pfu pAxCAHGF (the CAG promoter-driving HGF gene in adenovirus vector) (Exp. 2) were intrarectally introduced after induction of colitis by 4 % dextran sulfate sodium (DSS). METHODS Therapeutic effects were assessed by cell proliferation and apoptosis. RESULTS Rebamipide caused proliferation of epithelial cells at 10 days after treatment, and decreased apoptosis at 10, 14 and 21 days, compared with controls. Expression of HGF was greatly increased in rebamipide-treated mice. pAxCAHGF caused cell proliferation and apoptosis, which showed the same pattern as with rebamipide treatment. CONCLUSIONS Rectal administration of rebamipide is effective for DSS-induced colitis in association with induction of HGF.

Abstract
To evaluate the usefulness of computerized brain-surface dynamic voltage topography (DVT) of ictal electrocorticographic (ECoG) discharges to localize and identify epileptogenic areas, 3 patients with intractable frontal lobe epilepsy who underwent epilepsy surgery after chronic subdural electrode recording were assessed. Cortical surfaces and subdural electrodes were photographed during initial surgery to create an electrode map that could be superimposed onto a picture of the brain surface. DVT was performed by calculating sequential amplitudes of ictal ECoG discharges, which were then superimposed onto the cortical and electrode maps. In all cases, DVT clearly identified the ictal onset zone and the early propagation area on the operative field. DVT allowed recognition of spatial relationships between the epileptogenic area and structural abnormalities, functional cortex, and cortical veins; and was useful to decide on the resection area.

Abstract
Mitochondrial DNA (mtDNA) contains high levels of oxidative damage relative to nuclear DNA. A full, functional DNA base excision repair (BER) pathway is present in mitochondria, to repair oxidative DNA lesions. However, little is known about the organization of this pathway within mitochondria. Here, we provide evidence that the mitochondrial BER proteins are not freely soluble, but strongly associated with an inner membrane-containing particulate fraction. Uracil DNA glycosylase, oxoguanine DNA glycosylase and DNA polymerase γ activities all co-sedimented with this particulate fraction and were not dissociated from it by detergent (0.1% or 1.0% NP40) treatment. The particulate associations of these activities were not due to their binding mtDNA, which is itself associated with the inner membrane, as they also localized to the particulate fraction of mitochondria from 143B (TK−) ρ0 cells, which lack mtDNA. However, all of the BER activities were at least partially solubilized from the particulate fraction by treatment with 150–300 mM NaCl, suggesting that electrostatic interactions are involved in the association. The biological implications of the apparent immobilization of BER proteins are discussed.

Abstract
A 15-year-old girl developed intractable epilepsy following a right transcallosal resection of the intraventricular teratoma. Magnetic resonance (MR) imaging showed a T (2)-prolonged subcortical lesion in the right frontal lobe as well as a residual intraventricular tumor. The integration of the voltage topography of ictal onset activities of the scalp-recorded electroencephalogram (EEG) and a surface anatomy scan of MR images clearly revealed the epileptogenic area on the cortex above the subcortical lesion, with the propagation pattern towards the frontopolar area. Excision of the epileptogenic cortex and underlying gliosis resulted in a successful cessation of the epilepsy. This non-invasive EEG technique provided useful information that accurately localized the epileptogenic area on a large structural abnormality without invasive intracranial electrocorticographic monitoring.

Abstract
The human Ogg1 glycosylase is responsible for repairing 8-oxo-7,8-dihydroguanine (8-oxoG) in both nuclear and mitochondrial DNA. Two distinct Ogg1 isoforms are present; alpha-Ogg1, which mainly localizes to the nucleus and beta-Ogg1, which localizes only to mitochondria. We recently showed that mitochondria from rho(0) cells, which lack mitochondrial DNA, have similar 8-oxoG DNA glycosylase activity to that of wild-type cells. Here, we show that beta-Ogg1 protein levels are approximately 80% reduced in rho(0) cells, suggesting beta-Ogg1 is not responsible for 8-oxoG incision in mitochondria. Thus, we characterized the biochemical properties of recombinant beta-Ogg1. Surprisingly, recombinant beta-Ogg1 did not show any significant 8-oxoG DNA glycosylase activity in vitro. Since beta-Ogg1 lacks the C-terminal alphaO helix present in alpha-Ogg1, we generated mutant proteins with various amino acid substitutions in this domain. Of the seven amino acid positions substituted (317-323), we identified Val-317 as a novel critical residue for 8-oxoG binding and incision. Our results suggest that the alphaO helix is absolutely necessary for 8-oxoG DNA glycosylase activity, and thus its absence may explain why beta-Ogg1 does not catalyze 8-oxoG incision in vitro. Western blot analysis revealed the presence of significant amounts of alpha-Ogg1 in human mitochondria. Together with previous localization studies in vivo, this suggests that alpha-Ogg1 protein may provide the 8-oxoG DNA glycosylase activity for the repair of these lesions in human mitochondrial DNA. beta-Ogg1 may play a novel role in human mitochondria.

Abstract
Mitochondrial DNA (mtDNA) contains higher steady-state levels of oxidative damage and mutates at rates significantly greater than nuclear DNA. Oxidative lesions in mtDNA are removed by a base excision repair (BER) pathway. All mtDNA repair proteins are nuclear encoded and imported. Most mtDNA repair proteins so far discovered are either identical to nuclear DNA repair proteins or isoforms of nuclear proteins arising from differential splicing. Regulation of mitochondrial BER is therefore not expected to be independent of nuclear BER, though the extent to which mitochondrial BER is regulated with respect to mtDNA amount or damage is largely unknown. Here we have measured DNA BER activities in lysates of mitochondria isolated from human 143B TK(-) osteosarcoma cells that had been depleted of mtDNA (rho(0)) or not (wt). Despite the total absence of mtDNA in the rho(0) cells, a complete mitochondrial BER pathway was present, as demonstrated using an in vitro assay with synthetic oligonucleotides. Measurement of individual BER protein activities in mitochondrial lysates indicated that some BER activities are insensitive to the lack of mtDNA. Uracil and 8-oxoguanine DNA glycosylase activities were relatively insensitive to the absence of mtDNA, only about 25% reduced in rho(0) relative to wt cells. Apurinic/apyrimidinic (AP) endonuclease and polymerase gamma activities were more affected, 65 and 45% lower, respectively, in rho(0) mitochondria. Overall BER activity in lysates was also about 65% reduced in rho(0) mitochondria. To identify the limiting deficiencies in BER of rho(0) mitochondria we supplemented the BER assay of mitochondrial lysates with pure uracil DNA glycosylase, AP endonuclease and/or the catalytic subunit of polymerase gamma. BER activity was stimulated by addition of uracil DNA glycosylase and polymerase gamma. However, no addition or combination of additions stimulated BER activity to wt levels. This suggests that an unknown activity, factor or interaction important in BER is deficient in rho(0) mitochondria. While nuclear BER protein levels and activities were generally not altered in rho(0) cells, AP endonuclease activity was substantially reduced in nuclear and in whole cell extracts. This appeared to be due to reduced endogenous reactive oxygen species (ROS) production in rho(0) cells, and not a general dysfunction of rho(0) cells, as exposure of cells to ROS rapidly stimulated increases in AP endonuclease activities and APE1 protein levels.

Abstract
PURPOSE 5-Formyluracil (5-foU) is a potentially mutagenic lesion of thymine produced in DNA by ionizing radiation and various chemical oxidants. The present authors reported previously that MutM, Nth and Nei in Escherichia coli removed 5-foU from DNA. The present study identified 5-foU DNA glycosylases in Saccharomyces cerevisiae in order to clarify the repair mechanisms of 5-foU in eukaryotic cells. MATERIALS AND METHODS The borohydride-trapping assay and DNA-nicking assay were carried out to detect and characterize the repair activities for 5-foU in extracts from S. cerevisiae with oligonucleotides containing 5-foU at specific sites. RESULTS Two proteins in crude extracts from S. cerevisiae formed covalent complexes with oligonucleotides containing site-specific 5-foU in the presence of NaBH4. Extracts from S. cerevisiae strains defective in either the NTG1 or the NTG2 gene lacked either one or the other of these two proteins. Purified Ntg1 and Ntg2 were trapped in such complexes by the 5-foU-containing oligonucleotides in the presence of NaBH4. Furthermore, purified Ntg1 and Ntg2 efficiently cleaved the oligonucleotide at the 5-foU site. CONCLUSIONS The results indicate that both Ntg1 and Ntg2 are involved in the repair of 5-foU in DNA, and thereby serve to reduce mutations in S. cerevisiae.

Abstract
Alpha-tocopherol transfer protein (alpha-TTP), a 30 kDa cytosolic protein first described to be present in the liver and important for alpha-tocopherol trafficking, plays a major role in maintaining alpha-tocopherol levels in plasma, while alpha-tocopherol is known as the major lipid-soluble antioxidant. Expression of alpha-TTP has not only been described in animal model liver, but also in diverse other tissues such as rat brain or pregnant mouse uterus, the latter finding stressing the importance of alpha-TTP for embryogenesis and foetal development. In this study, we report the identification of alpha-TTP in human liver by anti-human alpha-TTP monoclonal antibodies made in rat and the cellular localization of alpha-TTP in term human placenta. By immunohistochemistry, intense staining of alpha-TTP was seen in syncytiotrophoblast as well as in villous and invading extravillous cytotrophoblast, while basal decidual cells showed slighter, but present staining of alpha-TTP. Foetal vessel endothelium remained unstained. It is therefore suggested that alpha-TTP may play a major role in supplying alpha-tocopherol to the foetus prior to delivery and is likely involved in maintaining adequate alpha-tocopherol levels in the foetus.

Abstract
PURPOSE 2-Hydroxyadenine (2-ohA) is an oxidation product of adenine generated in DNA by ionizing radiation and various chemical oxidants. 2-ohA has mutational potential comparable to that of 8-oxoguanine in bacteria and mammalian cells. Recent studies have shown that 2-ohA is removed from DNA by a human MutY homolog, MYH protein, in vitro. On the other hand, the repair mechanisms for 2-ohA in Escherichia coli are not yet understood. MATERIALS AND METHODS Gel shift assays were used to assess the binding activity of E. coli full-length MutY protein and its N-terminal (residues 1-226) domain (M25) to 2-ohA/G-, 2-ohA/A-, 2-ohA/C- and 2-ohA/T-containing 24-mer oligonucleotides. Furthermore, whether these proteins specifically cleave 2-ohA-containing duplex oligonucleotides was examined. RESULTS The purified MutY and M25 proteins had similar binding affinities to 2-ohA/G-, 2-ohA/A- and 2-ohA/C-containing oligonucleotides. MutY protein removed 2-ohA preferentially from 2-ohA/G mispairs. M25 protein showed the reduced catalytic activity for 2-ohA/G-containing oligonucleotides. CONCLUSIONS E. coli MutY protein has a DNA glycosylase activity that removes 2-ohA from 2-ohA/G mispairs in DNA. The C-terminal domain is required for the removal of 2-ohA from DNA, but is not crucial for binding to 2-ohA-containing oligonucleotides.

Abstract
We encountered 16 cases of venous thromboembolism (VTE) in women during pregnancy and/or puerperium over the past 15 years at our perinatal center, representing 0.14% of all patients who delivered babies. The present study was undertaken to analyze the risk factors, clinical course and outcomes in these 16 cases. The ages of the patients varied from 29 to 39 years. Four women had pulmonary embolism (PE), 3 of which after caesarean section (C/S) at 35 to 40 weeks, and one case after ovarian cystectomy at 13 weeks of gestation. Twelve cases had deep venous thrombosis (DVT), 4 of which during pregnancy, and the remaining 8 cases after C/S. Four patients who had DVT during a normal course of pregnancy had severe thrombophilia: antiphospholipid antibody syndrome, a history of thrombosis and antithrombin (AT) deficiency. They were treated with heparin with or without AT and had healthy babies via successful vaginal deliveries. The common risk factors in 3 cases of PE with C/S was prolonged bed rest due to threatened premature delivery with total placenta previa, uterine myoma and Ehlers-Danlos syndrome. Other risk factors were massive bleeding, and positive lupus anticoagulant. However, the case of the ovarian cystectomy had only one risk factor, which was obesity. This patient died but the remaining patients recovered with treatment. Because of the low incidence of thrombosis in the Japanese population, prophylactic anticoagulant therapy has not routinely been given to patients undergoing obstetrical operations. However, proper management including prophylactic anticoagulant therapy might be considered for risk patients, depending on the risk factors.

Abstract
Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome can occur at any time in the course of pregnancy and is associated with many complications including fatal stroke. A 37-year-old female presented with HELLP syndrome causing an intracerebral hematoma, which was treated by evacuation and mild hypothermia. Unexpected diffuse cerebral swelling occurred on the 15th day of the initially favorable postoperative course. Considerable impairment of consciousness persisted despite conservative therapy. Serial computed tomographic findings indicated delayed cerebral vasospasm as the cause of the swelling. Particularly careful management is required even beyond the first 2 weeks for patients with stroke as a complication of HELLP syndrome.

Abstract
The purpose of this study was to investigate the ultrastructure of saiga-antelope (Saiga tatarica) horn for proposing the mechanism of the initial mineralization. Horn is derived from horny tooth of Cyclostomata. The minerals in saiga horn were identified crystallographically using electron microscopy and X-ray diffraction techniques. Soft X-ray photographs revealed the degree of the mineralization pattern. However, the number of rings did not indicate the age of saiga. Mineral deposites were observed among well banded keratin fibers and composed of powder like crystals. This deposited crystals were found by the X-ray diffraction method to be octacalcium phospate (OCP) by comparing these periodic lattice fringes to JCPDS card data. The chemical formula of OCP is Ca8H2(PO4)6.5H2O. Evidences for the presence of OCP in mature hard tissues have never been obtained. This phenomenon described here may be characteristic of saiga horn because we have found no reports on this type of OCP mineralization in any other animal species. It is possible that OCP is the precursor in the initial mineralization step, indicating in a nucleation of mineral on the keratin fibers.

Abstract
A 49-year-old male had experienced diplopia for half a year. The intracranial pressure was markedly elevated (450 mmH2O). Neuroimaging revealed a tumor incompletely occluding the torcular herophili and the bilateral transverse sinuses without cerebral or cerebellar compression by the tumor. Both cortical veins and cervical veins were enlarged, and the Sylvian vein and Rabbe's vein and the tentorial sinus were collateral vessels. Biopsy was performed and histologic examination proved hemangiopericytoma. The patient underwent Gamma-knife treatment and the tumor decreased in size 3 months after the treatment.

Abstract
The pathways leading to G:C-->C:G transversions and their repair mechanisms remain uncertain. C/C and G/G mismatches arising during DNA replication are a potential source of G:C-->C:G transversions. The Escherichia coli mutHLS mismatch repair pathway efficiently corrects G/G mismatches, whereas C/C mismatches are a poor substrate. Escherichia coli must have a more specific repair pathway to correct C/C mismatches. In this study, we performed gel-shift assays to identify C/C mismatch-binding proteins in cell extracts of E. COLI: By testing heteroduplex DNA (34mers) containing C/C mismatches, two specific band shifts were generated in the gels. The band shifts were due to mismatch-specific binding of proteins present in the extracts. Cell extracts of a mutant strain defective in MutM protein did not produce a low-mobility complex. Purified MutM protein bound efficiently to the C/C mismatch-containing heteroduplex to produce the low-mobility complex. The second protein, which produced a high-mobility complex with the C/C mismatches, was purified to homogeneity, and the amino acid sequence revealed that this protein was the FabA protein of E.COLI: The high-mobility complex was not formed in cell extracts of a fabA mutant. From these results it is possible that MutM and FabA proteins are components of repair pathways for C/C mismatches in E.COLI: Furthermore, we found that Saccharomyces cerevisiae OGG1 protein, a functional homolog of E.COLI: MutM protein, could specifically bind to the C/C mismatches in DNA.

Abstract
To know the nature and mechanisms of spontaneous mutations in mitochondrial DNA (mtDNA), we determined, by direct cycle sequencing, the nucleotide sequence of the 3' terminal region of the mitochondrial 16S rRNA gene from chloramphenicol-resistant (CAP-R) mutants isolated in Chinese hamster V79 cells. Four different base substitutions were identified in common for the six CAP-R mutants. All mutations were heteroplasmic. One A to G transition was mapped at a site within the putative peptidyl transferase domain, the target region for chloramphenicol, and one G to A transition and two T to G transversions were located within the two different segments which form the stems of the hairpin loop structures attached to this key domain in the predicted secondary structure of 16S rRNA. The mutations detected in this study do not map to the same sites where CAP-R mutations were found previously in mammalian cells. Allele specific-PCR analyses revealed that all four mutations occurred on a single mutant-DNA molecule, but not on several ones independently. Together with the other previous reports, our data suggest that spontaneous mtDNA mutations may not be caused exclusively by oxidative DNA damage at least in 16S rRNA gene.

Abstract
Spectra of human dental enamel was recorded in the 200-400 nm UV region. It showed the weak band at 280 nm which were present in enamel protein. Excimer laser are gas lasers which emit light with photochemical decomposition. The wavelength depends on the 248 nm with krypton-fluoride. The enamel surfaces of extracted human teeth were exposed to KrF excimer laser by an energy density range from 29.6 to 3200 J/cm2. The purpose of this study was to investigate the changes with photo chemical reaction in enamel by light microscopy, SEM and X ray diffraction method. Results of analyses suggested that the observed changes of enamel exposed to this laser were the alpha and beta-tricalcium phosphate (TCP) phase in small amounts. No histological changes were observed in grain boundaries of cross sectioned lased enamel under light microscopy. The SEM examination revealed a roughened surface with bubble formation at 800-3200 J/cm2. SEM of etched enamel surface with 0.1 N HCl after laser irradiation at 400-800 J/cm2 showed the extension along the length of the rods. At 1600-3200 J/cm2, there appeared to be a melting of prism structures, because of conversion of photon energy into thermal energy. These results showed the KrF excimer laser irradiation to dental enamel might be a new type of treatment modality and diagnosis in preventive dentistry.

Abstract
Aspergillus DNA was detected by PCR in the serum sample of a 78-year-old man and galactomannan antigen of Aspergillus by sandwich ELISA was found. However, the infiltrative hyphae were not detected by the histopathologic examination of the lung. He developed hemoptysis, which required embolization of bronchial arteries. Aspergillus fumigatus was isolated from blood samples after embolization by the lysis centrifugation method. To our knowledge, this is probably the first case in which Aspergillus spp. has been isolated from the systemic circulatory blood in a patient with pulmonary aspergilloma after embolization.

Abstract
OBJECTIVE The detection of circulating Aspergillus galactomannan antigen is a useful tool for serodiagnosis of aspergillosis. However, the latex agglutination test for the detection of galactomannan is not completely reliable due to it's low sensitivity. The sandwich ELISA was developed to achieve high sensitivity. MATERIALS The sandwich immunocapture ELISA was evaluated by testing 56 sero-positive and 56 sero-negative samples of circulating galactomannan detected by LA test retrospectively. RESULTS Sixty of the samples were positive for galactomannan as measured by sandwich ELISA. Fifteen samples out of 56 samples negative by LA test were positive by ELISA and 4 samples out of 56 samples positive by LA test were negative by ELISA. Among 47 serum samples positive for anti-Aspergillus antibody, 14 samples were positive by ELISA. CONCLUSION In conclusion, galactomannan may be detected in more samples of by the new sandwich ELISA than by LA test.

Abstract
We measured the plasma concentration of itraconazole (ITCZ) in 18 patients who received ITCZ for the treatment of pulmonary aspergilloma. Abnormal laboratory values were observed in 4 out of 10 patients who received 200 mg/day, 1 out of 3 patients who received 300 mg/day, and 2 out of 5 patients who received 400 mg/day. Four patients discontinued ITCZ therapy because of adverse effects following the administration of 200 mg/day or 400 mg/day. The mean plasma ITCZ concentration was 622 ng/ml in patients treated with less than 4 mg/kg, and 1,352 ng/ml in patients treated with more than 4 mg/kg of ITCZ. The sensitivity of Aspergillus species to ITCZ was measured with the NCCLS microdilution method, using alamar blue indicator. The MIC50 of ITCZ was 0.5 microg/ ml for 25 strains of A. fumigatus, 4 microg/ml for 15 strains of A. niger, and 0.25 microg/ml for 10 strains of A. flavus. In conclusion, this study underscored the necessity of monitoring the plasma concentration of ITCZ for effective treatment of patients with pulmonary aspergilloma.

Abstract
An L-isoleucine-overproducing recombinant strain of E. coli, TVD5, was also found to overproduce L-valine. The L-isoleucine productivity of TVD5 was markedly decreased by addition of L-lysine to the medium. Introduction of a gene encoding feedback-resistant aspartokinase III increased L-isoleucine productivity and decreased L-valine by-production. The resulting strain accumulated 12 g/l L-isoleucine from 40 g/l glucose, and suppression of L-isoleucine productivity by L-lysine was relieved.

Abstract
Coffin-Lowry syndrome (CLS) is characterized by mental retardation, a peculiar face and deformities of the thorax and spine. A 33-year-old female with Coffin-Lowry syndrome (CLS), further complicated with atrial septal defect and ventricular tachycardia, underwent elective surgery for anterior cervical cyst. As difficult intubation had been anticipated, anesthesia was induced with continuous administration of propofol. After confirming that she could be ventilated by mask, vecuronium bromide, midazolam and fentanyl were given. The operation and anesthesia were conducted uneventfully. No complications occurred postoperatively. The use of propofol for slow induction of anesthesia was advantageous for hemodynamic stability in this case.

Abstract
We compared the usefulness of a polymerase chain reaction (PCR) assay for the early diagnosis of invasive pulmonary aspergillosis with the serodiagnosis of sufficient concentrations of galactomannan using the same serum samples. A patient was treated with prednisolone for the management of hepatitis. Computed tomography (CT) scan of the chest showed the nodular shadow with a cavity containing a clear fungus ball. DNA of Aspergillus spp. from a serum sample was detected and using the same serum sample, both latex agglutination and sandwich enzyme-linked immunosorbent assay (ELISA) of galactomannan were negative. PCR assay provides an early diagnosis of invasive pulmonary aspergillosis compared with ELISA of galactomannan.

Abstract
The influence of gatifloxacin, a new quinolone antibacterial, on the pharmacokinetics of theophylline (TP) was studied in five healthy adult male volunteers. After 200 mg of TP in sustained-release preparation was administered twice daily for 4 consecutive days, the same dose of TP and 200 mg of gatifloxacin were administered concurrently to the subjects twice daily for 5 consecutive days. Comparison of the pharmacokinetic parameters on day 4 of TP alone, and days 3 and 5 of co-administration revealed no significant differences in the maximum concentrations (Cmax), areas under the serum concentration-time curve (AUC0-12), total body clearances, and the amounts and proportions of TP and its metabolites in urine. One subject, however, showed 55% and 44% increases in Cmax and AUC0-12, respectively, on day 5 of co-administration relative to values on day 4 of TP alone. Thus, co-administration of gatifloxacin seemed to have little effect on the pharmacokinetics of TP. Further studies will be necessary to clarify the pharmacokinetic interaction between quinolones and TP, and it is recommended that, when both gatifloxacin and TP are administered, the background of the patients, such as their age, liver and cardiac functions, and other concomitant medications, be considered.
