Abstract
Gene doping is prohibited in horseracing. In a previous study, we developed a method for non-targeted transgene detection using DELLY, which is based on split-read (SR) and paired-end (PE) algorithms to detect structural variants, on WGS data. In this study, we validated the detection sensitivity of DELLY using artificially generated sequence data of 12 target genes. With DELLY, at least one intron was detected as a deletion in eight targeted genes using the 150 bp PE read WGS data, whereas all targeted genes were detected by DELLY using the 100 bp PE read data. The detection sensitivity was higher in 100 bp PE reads than in 150 bp PE reads, despite a lower total sequence coverage, probably because of mismatch tolerance between the mapped reads and reference genome. In addition, it was observed that the average intron size detected by SR alone was 293 bp and that that detected by both SR and PE was 8924 bp. Thus, we showed that transgenes with various intron-exon structures could be detected using DELLY, suggesting its application in gene-doping control in horses.

Abstract
Objective To examine the age in months at which infants visited outpatient clinics or emergency rooms for the first time for nonfatal injuries and to identify risk factors for the occurrence of these injuries. Study design Retrospective cohort study. Methods We used a health insurance claims database in Japan. Infants born between April 2012 and December 2014 were identified and followed until 12 months of age. We identified their first visit to outpatient clinics or emergency rooms because of nonfatal injuries (wounds/fractures, foreign bodies, and burns). Cox regression analysis was used to examine the association of nonfatal injuries with infants’ sex, birth order, and parental age. Results We identified 46,431 eligible infants. Of these, 7606 (16.4%) were brought to an outpatient clinic or emergency room for nonfatal injuries within 12 months of birth. Of the 7,606, 21.7% were aged ≤4 months and 44.7% ≤ 7 months. First-born infants were more likely to have wounds/fractures and burns. Conclusion One-fifth of first nonfatal infant injuries occurred within 4 months of age. Healthcare providers should provide early education about injury prevention, especially to caregivers of first-born infants. Nonfatal injuries within first year of birth occurred in 16% of infants. 22% of first injuries occurred within 4 months of birth. First-born infants were more likely to have wounds/fractures and burns.

Abstract
Fractures are medical conditions that compromise the athletic potential of horses and/or the safety of jockeys. Therefore, the reduction of fracture risk is an important horse and human welfare issue. The present study used molecular genetic approaches to determine the effect of genetic risk for fracture at four candidate SNPs spanning the myostatin (MSTN) gene on horse chromosome 18. Among the 3706 Japanese Thoroughbred racehorses, 1089 (29.4%) had experienced fractures in their athletic life, indicating the common occurrence of this injury in Thoroughbreds. In the case/control association study, fractures of the carpus (carpal bones and distal radius) were statistically associated with g.65809482T/C (P = 1.17 x 10-8 ), g.65868604G/T (P = 2.66 x 10-9 ), and g.66493737C/T (P = 6.41 x 10-8 ). In the retrospective cohort study using 1710 racehorses born in 2000, the relative risk (RR) was highest for male horses at g.65868604G/T, based on the dominant allele risk model (RR = 2.251, 95% confidence interval 1.407-3.604, P = 0.00041), and for female horses at g.65868604G/T, based on the recessive allele risk model (RR = 2.313, 95% confidence interval 1.380-3.877, P = 0.00163). Considering the association of these SNPs with racing performance traits such as speed, these genotypes may affect the occurrence of carpus fractures in Japanese Thoroughbred racehorses as a consequence of the non-genetic influence of the genotype on the distance and/or intensity of racing and training. The genetic information presented here may contribute to the development of strategic training programs and racing plans for racehorses that improve their health and welfare.

Abstract
Eight horse breeds-Hokkaido, Kiso, Misaki, Noma, Taishu, Tokara, Miyako and Yonaguni-are native to Japan. Although Japanese native breeds are believed to have originated from ancient Mongolian horses imported from the Korean Peninsula, the phylogenetic relationships among these breeds are not well elucidated. In the present study, we compared genetic diversity among 32 international horse breeds previously evaluated by the Equine Genetic Diversity Consortium, the eight Japanese native breeds and Japanese Thoroughbreds using genome-wide SNP genotype data. The proportion of polymorphic loci and expected heterozygosity showed that the native Japanese breeds, with the exception of the Hokkaido, have relatively low diversity compared to the other breeds sampled. Phylogenetic and cluster analyses demonstrated relationships among the breeds that largely reflect their geographic distribution in Japan. Based on these data, we suggest that Japanese horses originated from Mongolian horses migrating through the Korean Peninsula. The Japanese Thoroughbreds were distinct from the native breeds, and although they maintain similar overall diversity as Thoroughbreds from outside Japan, they also show evidence of uniqueness relative to the other Thoroughbred samples. This is the first study to place the eight native Japanese breeds and Japanese Thoroughbred in context with an international sample of diverse breeds.

Abstract
BACKGROUND Repeated topical application of indomethacin is common in Japanese racehorses, despite the lack of pharmacokinetic data. OBJECTIVES To determine the concentrations of indomethacin and its metabolite, desmethylindomethacin, in plasma and urine of Thoroughbreds topically treated repeatedly with indomethacin. STUDY DESIGN In vivo experimental. METHODS Seven female Thoroughbreds were topically treated with 50 g of 1% indomethacin cream per horse to the back and hips (500 mg of indomethacin/head/2400 cm2 , 0.21 g/cm2 ) for 3 consecutive days. Samples were pretreated by protein precipitation for plasma and liquid-liquid extraction with ethyl acetate after hydrolysis with hydrochloric acid for urine. The concentrations of indomethacin and desmethylindomethacin in plasma and urine were measured by liquid chromatography-mass spectrometry. RESULTS Indomethacin was quantifiable in plasma up to 48-72 h and in urine up to 96 h after the final application. Desmethylindomethacin was quantifiable in plasma up to 48 h and in urine up to 72-96 h after the final application. MAIN LIMITATIONS The relationship between the local and systemic indomethacin concentrations after the topical application was not clarified. CONCLUSIONS Pharmacokinetic data were acquired for repeated topical administration of 1% indomethacin cream to Thoroughbreds. Hydrolysing urine samples with hydrochloric acid was effective for the analysis of indomethacin and its metabolite, and indomethacin may be an excellent marker analyte for doping tests. The estimated withdrawal time based on the limit of detection was 342 h.

Abstract
There are few data regarding the role of probiotics as a dietary intervention in the management of obesity in children. An open prospective examination was conducted to clarify the effects of Lactobacillus casei strain Shirota (LcS)-containing beverages in obese children. We compared the intestinal microbiota and organic acid levels between 12 obese (average age, 10.8 years; body mass index (BMI) Z score, 2.7±1.7) and 22 control children(average age, 8.5 years; BMI Z score, 0.1±0.7), and pre- and post-intervention in the obese children. The obese group underwent diet and exercise therapy for 6 months and then were given an LcS beverage daily for another 6 months and the body weight and serological markers were monitored. Significant reductions in the faecal concentrations of Bifidobacterium (obese group, 7.9±1.5 vs non-obese group, 9.8±0.5 Log10cells/g; P<0.01) along with a significant decline in the Bacteroides fragilis group, Atopobium cluster and Lactobacillus gasseri subgroup, and acetic acid (obese group, 45.1±16.9 vs non-obese group, 57.9±17.6 μmol/g; P<0.05) were observed in the obese group at baseline. A significant decline in body weight (-2.9±4.6%; P<0.05) and an elevation in the high density lipoprotein cholesterol level (+11.1±17.6%; P<0.05) were observed 6 months after ingestion of the LcS beverage compared to baseline. Furthermore, a significant increase in the faecal concentration of Bifidobacterium (7.0±1.2 before ingestion vs 9.1±1.2 Log10cells/g after ingestion; P<0.01) and an apparent increase in the acetic acid concentration (7.0±1.2 before ingestion vs 9.1±1.2 Log10cells/g after ingestion; P<0.01) were observed 6 months after ingestion. LcS contributed to weight loss while also improving the lipid metabolism in obese children via a significant increase in the faecal Bifidobacterium numbers and the acetic acid concentration.

Abstract
Herein we investigated the intestinal carriage of α-toxigenic and enterotoxigenic Clostridium perfringens during infancy, focusing on its association with other gut microbes and mode of delivery and feeding. Faecal samples from 89 healthy term infants were collected at age 7 days, 1 month, 3 months, 6 months and 3 years. C. perfringens was quantified by qPCR; other gut bacteria were quantified by reverse-transcription-qPCR. Alpha-toxigenic C. perfringens was detected in 3.4% infants at day 7 but was present in 35-40% infants at subsequent time-points, with counts ranging from 103-107 cells/g faeces. Enterotoxigenic C. perfringens remained undetected at day 7 but was detected in 1.1, 4.5, 10.1 and 4.5% infants at 1 month, 3 months, 6 months and 3 years, respectively. Intriguingly, infants carrying α-toxigenic C. perfringens had lower levels of Bacteroides fragilis group, bifidobacteria, lactobacilli and organic acids as compared to non-carriers. Further analyses revealed that, compared to vaginally-born infants, caesarean-born infants had higher carriage of C. perfringens and lower levels of B. fragilis group, bifidobacteria, lactobacilli and faecal organic acids during first 6 months. Compared to formula-fed infants, breast-fed infants were slightly less often colonised with C. perfringens; and within caesarean-born infants, breast-fed infants had slightly lower levels of C. perfringens and higher levels of B. fragilis group, bifidobacteria, and lactobacilli than formula-fed infants. This study demonstrates the quantitative dynamics of toxigenic C. perfringens colonisation in infants during the early years of life. Caesarean-born infants acquire a somewhat perturbed microbiota, and breast-feeding might be helpful in ameliorating this dysbiosis. Higher carriage of toxigenic C. perfringens in healthy infants is intriguing and warrants further investigation of its sources and clinical significance in infants, particularly the caesarean-born who may represent a potential reservoir of this opportunistic pathogen and might be more prone to associated illnesses.

Abstract
OBJECTIVE Prevention of frail skin is important in older people because frail skin is associated with a risk of injury in this population. In this study, we investigated the association of nutritional status and habitual dietary intake with skin conditions in community-dwelling older people. DESIGN Cross-sectional study. SETTING Three community settings in Japan from autumn to winter. PARTICIPANTS Older people aged ≥65 years without care-need certification (n=118). MEASUREMENTS Malnutrition and obesity were evaluated to assess the nutritional status. Nutrient and food group intakes per 1000 kcal were evaluated using a brief self-administered diet history questionnaire. Dietary patterns based on food groups were evaluated by principal component analysis. Skin condition parameters, including stratum corneum hydration, appearance of xerosis (specific symptom sum score [SRRC score]), and dermal intensity by high-frequency ultrasonography, were measured on a lower leg. Multiple linear regression analysis was performed with adjustment for confounders. RESULTS The mean (standard deviation) age was 74.1 (4.8) years, and 83.1% of participants were female. A higher intake of plant fat (p=0.018) was associated with a lower SRRC score. Higher intakes of α-tocopherol (p=0.050) and vitamin C (p=0.017) were associated with increased dermal intensity. A body mass index ≥25 (p=0.016) was associated with decreased dermal intensity. A dietary pattern characterized by higher vegetable and fruit intake was associated with a better skin condition. CONCLUSION Plant fat, antioxidant vitamins, and a dietary pattern characterized by vegetables and fruits showed positive and obesity showed negative associations for frail skin in community-dwelling older people.

Abstract
Phosphatidylserine (PtdSer) is a phospholipid that is abundant in eukaryotic plasma membranes. An ATP-dependent enzyme called flippase normally keeps PtdSer inside the cell, but PtdSer is exposed by the action of scramblase on the cell's surface in biological processes such as apoptosis and platelet activation. Once exposed to the cell surface, PtdSer acts as an 'eat me' signal on dead cells, and creates a scaffold for blood-clotting factors on activated platelets. The molecular identities of the flippase and scramblase that work at plasma membranes have long eluded researchers. Indeed, their identity as well as the mechanism of the PtdSer exposure to the cell surface has only recently been revealed. Here, we describe how PtdSer is exposed in apoptotic cells and in activated platelets, and discuss PtdSer exposure in other biological processes.

Abstract
Procaterol (PCR) is a beta-2-adrenergic bronchodilator widely used in Japanese racehorses for treating lower respiratory disease. The pharmacokinetics of PCR following single intravenous (0.5 μg/kg) and oral (2.0 μg/kg) administrations were investigated in six thoroughbred horses. Plasma and urine concentrations of PCR were measured using liquid chromatography-mass spectrometry. Plasma PCR concentration following intravenous administration showed a biphasic elimination pattern. The systemic clearance was 0.47 ± 0.16 L/h/kg, the steady-state volume of the distribution was 1.21 ± 0.23 L/kg, and the elimination half-life was 2.85 ± 1.35 h. Heart rate rapidly increased after intravenous administration and gradually decreased thereafter. A strong correlation between heart rate and plasma concentration of PCR was observed. Plasma concentrations of PCR after oral administration were not quantifiable in all horses. Urine concentrations of PCR following intravenous and oral administrations were quantified in all horses until 32 h after administration. Urine PCR concentrations were not significantly different on and after 24 h between intravenous and oral administrations. These results suggest that the bioavailability of orally administrated PCR in horses is very poor, and the drug was eliminated from the body slowly based on urinary concentrations. This report is the first study to demonstrate the pharmacokinetic character of PCR in thoroughbred horses.

Abstract
OBJECTIVE There are several inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) combinations currently used to treat asthmatic patients, but the differences in the clinical effects of these ICS/LABAs are currently unknown. We herein evaluated the effects of two currently available ICS/LABA combinations in a real-world setting. METHODS A fluticasone propionate/salmeterol combined Discus inhaler (FP/SM; 250/50 μg bid) was switched to a budesonide/formoterol Turbuhaler inhaler (BUD/FM; 160/4.5 μg two inhalations bid) and FP/SM (500/50 μg bid) was also switched to BUD/FM (160/4.5 μg four inhalations bid) in symptomatic asthmatic patients treated with FP/SM over 20 years of age. RESULTS Sixty patients were enrolled in this study, and the scores of the asthma control test (ACT) and asthma control questionnaire-5 item version (ACQ5) were significantly improved 4 and 8 weeks after the switch to ICS/LABA treatments, and well-controlled asthma (ACQ5 score <0.75) and good control (ACT score >20) was achieved in 54 (90%) and 40 (66.7%) patients, respectively, at 8 weeks. The spirometric analysis revealed significant improvements of the values of the peak expiratory flow (PEF) and forced expiratory volume in one second (FEV1) after switching from FP/SM to BUD/FM, and significantly improved small airway impairments ([Formula: see text]50 and [Formula: see text]25) were observed in patients treated with high-dose ICS/LABA. These subjective and objective improvements were also seen in patients aged over 65 years old. CONCLUSION These data demonstrated that changing the combined ICS/LABA inhaler from FP/SM to BUD/FM can lead to more effective management of symptomatic patients with asthma, especially in patients treated with high-dose ICS/LABA.

Abstract
We herein describe a discrepancy between the clinical image and pathological findings in a non-small cell lung cancer patient with an epidermal growth factor receptor (EGFR) mutation who underwent surgical resection after gefitinib treatment. The patient was a 66-year-old female with c-stage IIIA lung adenocarcinoma harboring an EGFR gene mutation; she was surgically treated after receiving gefitinib. The pathological examination revealed adenocarcinoma, and the pathologically therapeutic effect was considered to be slight or of no response. EGFR T790M mutation and MET amplification were not present. The pathologically therapeutic effect is generally well correlated with the response rate after induction therapy. In this case, there was a discrepancy between the clinical image and pathological findings. Our findings, therefore, raise questions about the role of surgery after EGFR-tyrosine kinase inhibitor treatment.

Abstract
In the present study, we evaluated the antiemetic effect of aprepitant in combination with 5-hydroxytryptophan(5-HT3) receptor antagonist and dexamethasone for chemotherapy-induced emesis and nausea in lung cancer patients treated with carboplatin-based systemic chemotherapy using the Functional Living Index-Emesis, an emesis- and nausea-specific quality of life(QOL)questionnaire. Patients experiencing emesis and/or nausea during and/or after previous courses of carboplatin-based chemotherapy received aprepitant in the following treatment cycle with the same anti-cancer agent. Emesis- and nausea-specific QOL aspects were significantly improved with the addition of aprepitant to the existing regimen containing dexamethasone and 5-HT3 receptor antagonist. Our result suggests that combined antiemetic treatment with aprepitant, dexamethasone, and 5-HT3 receptor antagonist is more effective in lung cancer patients receiving carboplatin-based systemic chemotherapy than dexamethasone and 5-HT3 receptor antagonist alone.

Abstract
Objective Impaired clearance of apoptotic cells is a potential trigger of systemic lupus erythematosus (SLE). Milk fat globule epidermal growth factor 8 (MFG-E8) plays an important role in the clearance of dying cells. Previously, we reported serum MFG-E8 was elevated in some SLE patients. Here we further investigated the prevalence of MFG-E8 in active SLE and other autoimmune diseases and also tried to clarify the characteristics of MFG-E8-positive and -negative SLE. Methods Serum MFG-E8 was measured in 40 active non-treated SLE patients, 104 disease controls and 104 healthy controls by ELISA. Clinical characteristics and serum cytokine profiles were compared between MFG-E8-positive and MFG-E8-negative SLE patients. Results Prevalence of MFG-E8 was significantly higher in SLE patients (40%) than in various controls ( p < 0.05). MFG-E8 level became negative after treatment, and increased again upon relapse. When compared, MFG-E8-positive SLE patients showed higher immune complex ( p = 0.021) and lower complement ( p = 0.004 for CH50). In contrast, MFG-E8-negative SLE patients tended to show higher CRP ( p = 0.094). There was a positive correlation between MFG-E8 level and immune complex level ( rs = 0.49, p = 0.049). TNF-α ( p = 0.019), IFN-γ ( p = 0.031) and IL-10 ( p = 0.013) were significantly higher in MFG-E8-positive SLE. Conclusion MFG-E8-positive SLE and -negative SLE may have different clinical features, the one with stronger immunological response and the other with stronger inflammatory response, and those two groups may be two distinct subtypes of SLE driven by different mechanisms. Further, MFG-E8 could be used as a biomarker for diagnosis and monitoring of disease activity in certain SLE patients.

Abstract
In order to create Fe2O3 and Fe2O3·H2O nanoparticles, various polymers were used as dispersing agents, and the resulting effects on the dispersibility and nanoparticulation of the iron oxides were evaluated. It was revealed that not only the solution viscosity but also the molecular length of the polymers and the surface tension of the particles affected the dispersibility of Fe2O3 and Fe2O3·H2O particles. Using the dispersing agents 7.5% hydroxypropylcellulose-SSL, 6.0% Pharmacoat 603, 5.0% and 6.5% Pharmacoat 904 and 7.0% Metolose SM-4, Fe2O3 nanoparticles were successfully fabricated by wet milling using Ultra Apex Mill. Fe2O3·H2O nanoparticles could also be produced using 5.0% hydroxypropylcellulose-SSL and 4.0 and 7.0% Pharmacoat 904. The index for dispersibility developed in this study appears to be an effective indicator of success in fabricating nanoparticles of iron oxides by wet milling using Ultra Apex Mill.

Abstract
The bacterial species in the Streptococcus anginosus group (S. constellatus, S. anginosus, S. intermedius) are important causative pathogens of bacterial pneumonia, pulmonary abscesses and empyema. However, the bacteria in this group are primarily oral resident bacteria and unable to grow significantly on ordinary aerobic culture media. We experienced a case of pneumonia and empyema caused by Streptococcus intermedius detected using a 16S rRNA gene sequencing analysis of bronchoalveolar lavage fluid and pleural effusion, but not sputum. Even when applying the molecular method, sputum samples are occasionally unsuitable for identifying the causative pathogens of lower respiratory tract infections.

Abstract
Moxifloxacin (MFLX) is a respiratory quinolone, and is effective against not only Gram-positive and negative bacteria but also anaerobes. There has been no prospective studies evaluating the efficacy and safety of MFLX in patients with nursing and healthcare-associated pneumonia (NHCAP). Therefore, we assessed the efficacy and safety of MFLX in patients with NHCAP. NHCAP patients with mild and moderate severity assessed by the A-DROP system in community-acquired pneumonia guideline proposed by Japan Respiratory Society visited our hospitals from April 2011 to March 2012. Clinical symptoms, chest X-ray films and/or computed tomography, peripheral white and red blood cell and platelet counts, serum CRP, AST, ALT, BUN, creatinine were evaluated. Forty patients were eventually evaluated, and average age was 74.1 years old, male/female were 21/19, 92.5% (37/40) of them had one or more comorbidities. Median duration of MFLX administration was 7.1 days (4-15 days). The efficacy of MFLX in all patients was 87.5% (35/40). The efficacies in each age group were 87.9% (aged over 65 years old), 85.7% (aged under 64 years old), and in each pneumonia severity group by the A-DROP system were 91.7% (mild), 85.7% (moderate). Diarrhea and swelling of the breast were observed in one patient (2.5%) after starting MFLX administration. Mild elevated transaminases were observed in three patients (7.5%), and mild renal dysfunction was observed in two patients (5.0%). All abnormally increased levels of transaminases and serum creatinine were recovered after a cessation of MFLX. MFLX is effective and safe in patients with NHCAP.

Abstract
AIM The aim of this study was to compare the growth of Japanese infants that were exclusively breastfed to those of national references and World Health Organization (WHO) standards. METHODS Mothers, who delivered a normal term baby and had been exclusively breastfeeding for at least 4 months, were enrolled. The lengths, body weights and head circumferences of 647 children, aged 0-24 months, were obtained and compared to national references and WHO standards. RESULTS Comparisons of the national references for both length and body weight indicated that breastfed infants were significantly shorter and lighter almost throughout the first 24 months. Conversely, head circumferences of breastfed infants were significantly larger at 1 and 6 months of age in boys and 6 months in girls. Compared to WHO standards, similar trends to the comparisons with national references were found. CONCLUSION There were significant differences identified between the growth of breastfed infants and existing national references and WHO standards.

Abstract
BACKGROUND Molecular biological modalities with better detection rates have been applied to identify the bacteria causing infectious diseases. Approximately 10-48% of bacterial pathogens causing community-acquired pneumonia are not identified using conventional cultivation methods. This study evaluated the bacteriological causes of community-acquired pneumonia using a cultivation-independent clone library analysis of the 16S ribosomal RNA gene of bronchoalveolar lavage specimens, and compared the results with those of conventional cultivation methods. METHODS Patients with community-acquired pneumonia were enrolled based on their clinical and radiological findings. Bronchoalveolar lavage specimens were collected from pulmonary pathological lesions using bronchoscopy and evaluated by both a culture-independent molecular method and conventional cultivation methods. For the culture-independent molecular method, approximately 600 base pairs of 16S ribosomal RNA genes were amplified using polymerase chain reaction with universal primers, followed by the construction of clone libraries. The nucleotide sequences of 96 clones randomly chosen for each specimen were determined, and bacterial homology was searched. Conventional cultivation methods, including anaerobic cultures, were also performed using the same specimens. RESULTS In addition to known common pathogens of community-acquired pneumonia [Streptococcus pneumoniae (18.8%), Haemophilus influenzae (18.8%), Mycoplasma pneumoniae (17.2%)], molecular analysis of specimens from 64 patients with community-acquired pneumonia showed relatively higher rates of anaerobes (15.6%) and oral bacteria (15.6%) than previous reports. CONCLUSION Our findings suggest that anaerobes and oral bacteria are more frequently detected in patients with community-acquired pneumonia than previously believed. It is possible that these bacteria may play more important roles in community-acquired pneumonia.

Abstract
OBJECTIVE Erlotinib has been reported to be useful for treatment of non-small-cell lung cancer harboring mutation of the epidermal growth factor receptor gene EGFR-mt. However, no prospective trial has yet assessed the utility of erlotinib in Japanese patients. METHODS Patients with EGFR-mt (exon 19/21) non-small-cell lung cancer who had previously received one to two chemotherapy regimens were enrolled in this trial. Erlotinib was initially administered at a dose of 150 mg/day orally until disease progression or unacceptable toxicities occurred. The primary endpoint was the objective response rate. RESULTS Twenty-six patients were enrolled between February 2009 and January 2011. Objective response was observed in 14 patients (53.8%, 95% confidence interval: 33.4-73.4%), and the disease control rate reached 80.8% (95% confidence interval: 60.7-93.5%). After a median follow-up time of 17.3 months (range: 5.8-29.5 months), the median progression-free survival was 9.3 months (95% confidence interval: 7.6-11.6 months). The median survival time is yet to be determined. Major toxicities were skin disorder and liver dysfunction; most episodes were grade 2 or less, and all were tolerable. Only one patient with grade 3 skin rash discontinued the study. No patients developed interstitial lung disease, and there were no treatment-related deaths. CONCLUSIONS This prospective study is the first to have investigated the usefulness of erlotinib in Japanese patients with previously treated EGFR-mt non-small-cell lung cancer. Although this trial could not meet the primary endpoint, erlotinib was well tolerated and showed clinical benefit such as promising disease control rate or progression-free survival in this population, similar to gefitinib.

Abstract
Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-neoplastic disease that is characterized by a proliferation of histiocytes mostly in lymph nodes. However, the etiological mechanism of RDD still remains unclear. Intrathoracic manifestations of RDD are only observed in 2% of patients with RDD. Spontaneous remission was reported in about 20% of patients with RDD; however, there are no reports of an intrathoracic manifestation of RDD that showed a spontaneous remission within a short period of time. A 64-year-old Japanese female with dry cough and left chest pain was introduced to our hospital, and computed tomography revealed a pulmonary nodular lesion and enlarged mediastinal lymph nodes. The bronchial specimen obtained from the abnormal mucosal lesion showed massive infiltration of histiocytes underneath the bronchial epithelium and emperipolesis, a typical pathological finding in RDD, which is characterized by the presence of histiocyte-like cells engulfing intact lymphocytes. These histiocytes were positive for S-100 (one of the known positive markers of RDD) and for CD68 (a marker for various cells of the macrophage lineage). All these findings are consistent with the diagnosis of RDD. These radiological and endoscopic findings spontaneously resolved within four months without any treatment. In conclusion, clinicians should be aware of this disease as one of differential diagnoses of pulmonary nodules in combination with mediastinal lymph node enlargements, especially in order to differentiate it from primary lung cancer.

Abstract
We herein report a rare case of pulmonary mucosa-associated lymphoid tissue (p-MALT) lymphoma with multiple cystic lesions. A previously healthy 58-year-old Japanese woman visited our hospital for an evaluation of abnormal chest computed tomography (CT) findings. Chest CT revealed multiple cystic lesions in both lungs, and she was diagnosed as having p-MALT lymphoma based on the pathological findings. The patient had no underlying autoimmune diseases. She has not received any chemotherapy and has been stable for two years. This case suggests that, although rare, the possibility of p-MALT lymphoma should be considered in patients with multiple cystic lung diseases.

Abstract
Two major apoptosis pathways, the mitochondrial and death receptor pathways, are well recognized. Here we established cell lines from the fetal thymus of Apaf-1-, Caspase-9-, or Bax/Bak-deficient mice. These cell lines were resistant to apoptosis induced by DNA-damaging agents, RNA or protein synthesis inhibitors, or stress in the endoplasmic reticulum. However, they underwent efficient apoptosis when treated with kinase inhibitors such as staurosporine and H-89, indicating that these inhibitors induce a caspase-dependent apoptosis that is different from the mitochondrial pathway. CrmA, a Caspase-8 inhibitor, did not prevent staurosporine-induced apoptosis of fetal thymic cell lines, suggesting that the death receptor pathway was also not involved in this process. The staurosporine-induced cell death was inhibited by okadaic acid, a serine/threonine phosphatase inhibitor, suggesting that dephosphorylation of a proapoptotic molecule triggered the death process, or that phosphorylation of an antiapoptotic molecule could block the process. Cells of various types (fetal thymocytes, bone marrows, thymocytes, and splenocytes), but not embryonic fibroblasts, were sensitive to the noncanonical staurosporine-induced apoptosis, suggesting that the noncanonical apoptosis pathway is tissue specific.
