Abstract
Corynebacterium ulcerans is a closely related bacterium to the diphtheria bacterium C. diphtheriae, and some C. ulcerans strains produce toxins that are similar to diphtheria toxin. C. ulcerans is widely distributed in the environment and is considered one of the most harmful pathogens to livestock and wildlife. Infection with C. ulcerans can cause respiratory or nonrespiratory symptoms in patients. Recently, the microorganism has been increasingly recognized as an emerging zoonotic agent of diphtheria-like illness in Japan. To clarify the overall clinical characteristics, treatment-related factors, and outcomes of C. ulcerans infection, we analyzed 34 cases of C. ulcerans that occurred in Japan during 2001-2020. During 2010-2020, the incidence rate of C. ulcerans infection increased markedly, and the overall mortality rate was 5.9%. It is recommended that adults be vaccinated with diphtheria toxoid vaccine to prevent the spread of this infection.

Abstract
BACKGROUND Some patients with sarcoidosis experience worsening of pulmonary lesions. However, no biomarker has been identified that reflects pulmonary disease status in sarcoidosis. We investigated the usefulness of potential markers of pulmonary fibrosis in patients with sarcoidosis. METHODS Plasma matrix metalloproteinase 7 (MMP-7), CC-chemokine ligand 18 (CCL-18), and periostin levels were evaluated in 60 patients with sarcoidosis and 30 healthy controls; bronchoalveolar lavage fluid levels were analyzed in 22 patients with sarcoidosis. To determine the usefulness of these markers, we explored potential correlations between these markers and sarcoidosis clinical characteristics. RESULTS Plasma MMP-7, CCL-18, and periostin concentrations were significantly higher in patients with sarcoidosis than those in healthy controls. MMP-7 concentrations in plasma and bronchoalveolar lavage fluid were higher in patients with sarcoidosis with parenchymal infiltration than in those without lung lesions. Moreover, MMP-7 concentration was negatively correlated with pulmonary function. CONCLUSION Among these novel biomarkers, MMP-7 most precisely reflected pulmonary sarcoidosis disease status and thus, might be useful for diagnosing and evaluating sarcoidosis, particularly in patients with pulmonary parenchymal lesions.

Abstract
Although numerous recent studies have reported the development of sarcoidosis in patients treated with tumor necrosis factor alpha (TNF-α) inhibitors, it is unclear whether the pathogenesis of drug-induced sarcoidosis is identical to that of spontaneous sarcoidosis. We herein present the case of a patient who developed sarcoidosis 6 months after the introduction of etanercept as treatment for rheumatoid arthritis. Typical clinical symptoms with noncaseating epithelioid granulomas detected in a mediastinal lymph node specimen were consistent with the diagnosis of sarcoidosis. Immunohistochemistry revealed Propionibacterium acnes in the noncaseating granulomas. The present findings suggest that Propionibacterium acnes is a cause of sarcoidosis, even when the disease is induced by TNF-α inhibitors.

Changes in the expression of α-tocopherol-related genes in liver and mammary gland biopsy specimens of peripartum dairy cows. J Dairy Sci 2018; 101:5277-5293.

Abstract
Blood α-tocopherol (α-Toc) concentrations decline gradually throughout the prepartum period, reaching the nadir after calving in dairy cows. The 6 α-Toc-related molecules [α-Toc transfer protein (TTPA); afamin; scavenger receptor class B, Type I; ATP-binding cassette transporter A1; tocopherol-associated protein (SEC14L2); and cytochrome P450 family 4, subfamily F, polypeptide 2 (CYP4F2)] are expressed in liver and other peripheral tissues. These molecules could regulate α-Toc transport, blood concentrations, and metabolism of α-Toc. Therefore, the aim of this study was to evaluate the changes in the expression of α-Toc-related genes in liver and mammary gland tissues of dairy cows around calving, which have remained elusive until now. In experiment (Exp.) 1, 28 multiparous Holstein cows were used (from -5 to 6 wk relative to parturition) to monitor the changes in dietary α-Toc intake, blood concentrations of α-Toc, and lipoproteins; in Exp. 2, 7 peripartum Holstein cows were used (from -4 to 4 wk relative to parturition) for liver tissue biopsy; and in Exp. 3, 10 peripartum Holstein cows were used (from -8 to 6 wk relative to parturition) to carry out the mammary gland tissue biopsy and milk sampling. In Exp. 1, the serum α-Toc concentrations declined gradually with decreasing amount of α-Toc intake and plasma high-density lipoprotein concentrations toward calving time. However, in the early lactation period after calving, serum α-Toc concentrations remained at a lower concentration despite the recovery of α-Toc intake and plasma high-density lipoprotein concentrations. In Exp. 2, just after calving, the TTPA, SEC14L2, afamin, and albumin mRNA expression levels in the liver were temporarily downregulated, and the hepatic mRNA levels of endoplasmic reticulum stress-induced unfolded protein response markers and acute-phase response marker increased at calving. In Exp. 3, the concentrations of α-Toc in colostrum were greater than those in precolostrum (samples were collected at wk -1 relative to parturition) and mature milk. The expression of TTPA, SEC14L2, and CYP4F2 mRNA in bovine mammary gland tissue was detected. However, TTPA and SEC14L2 mRNA expressions showed the opposite trends: the expression levels of TTPA mRNA peaked whereas SEC14L2 mRNA reached a nadir at calving. These results indicate that the expression of α-Toc-related genes involved in specific α-Toc transfer and metabolism in the liver and mammary gland are altered during calving. Moreover, these changes might be associated with the maintenance of lower serum α-Toc concentrations after calving.

Abstract
Invasive pulmonary aspergillosis (IPA) usually occurs in patients with severe immunodeficiencies involving neutropenia. Underlying lung disease is a well-known risk factor of IPA; however, interstitial lung disease has not been recognized as a risk factor of IPA. We herein report a patient with fibrotic nonspecific interstitial pneumonia who experienced IPA without neutropenia. His IPA was fatal and showed unusually slow disease progression over one month. The computed tomography findings showed only nonspecific consolidation and no typical lesions suggestive of IPA. Finally, the autoptic findings revealed numerous Aspergillus fungi, neutrophilic pulmonary necrosis, and vessels invaded by Aspergillus fungi.

Abstract
Cancer initiation and progression are defined by the behavior of cancer cells per se and the development of tumor tissues, both of which are modulated by crosstalk between cancer cells and the surrounding microenvironment. Advances in cancer research have highlighted the significance of constant evolution of the tumor microenvironment, leading to tumor formation, metastasis and refractoriness to therapy. MicroRNAs (miRNAs) are small non-coding RNAs that function as major players of posttranscriptional gene regulation in diverse biological processes. They function as both tumor suppressors and promoters in many aspects of the autonomous behavior of cancer cells. Theoretically, dysfunction in the gene regulatory networks of cancer cells is one of the major driving forces for alterations of ostensibly normal surrounding cells. In this context, the core targets of miRNAs, termed miRNA regulons, are currently being expanded to include various modulators of the tumor microenvironment. Recent advances have highlighted two important roles played by miRNAs in the evolution of tumor microenvironments: miRNAs in tumor cells transform the microenvironment via non-cell-autonomous mechanisms, and miRNAs in neighboring cells stabilize cancer hallmark traits. These observations epitomize the distal and proximal functions of miRNAs in tumor microenvironments, respectively. Such regulation by miRNAs affects tumor angiogenesis, immune invasion and tumor-stromal interactions. This review summarizes recent findings on the mechanisms of miRNA-mediated regulation of tumor microenvironments, with a perspective on the design of therapeutic interventions.

Abstract
UNLABELLED This study investigated differences in prevalence of the androgen-regulated transmembrane protease serine 2 (TMPRSS2) and ETS transcription factor family member, v-ets erythroblastosis virus E26 oncogene homolog (ERG) fusion gene (TMPRSS2-ERG fusions) in clinically localized prostate cancer Japanese and German patients. A total of 105 specimens, including 69 Japanese and 36 German patients, were collected. The status of TMPRSS2-ERG fusion was determined by fluorescence in situ hybridization, and correlations of the TMPRSS2-ERG fusion with clinicopathological characteristics and immunohistochemistry were studied. Gene fusions were identified in 20% (14/69) of Japanese and 53% (19/36) of German patients (P < 0.001). The difference in the type of gene fusion between the two ethnic groups was statistically significant (P=0.024). Overexpression of ERG protein was significantly associated with gene fusion. Biochemical recurrence was significantly higher in patients with ERG overexpression than in those without, and not related to TMPRSS2-ERG fusion status. Interestingly, two types of gene fusions (deletion and increase of copy number) were significantly associated with increased p53 expression (P = 0.005). Association of specific gene fusions harboring higher genomic alterations with p53 expression levels suggests that p53 mutation might drive more aggressive arrangements of TMPRSS2-ERG fusion in prostate cancer. KEYWORDS ERG, p53, prostate cancer, TMPRSS2-ERG fusion.

Abstract
BACKGROUND The roles of M2 and M3 muscarinic receptor subtypes in the regulation of gut motor activity were investigated. METHODS We simultaneously recorded changes in the intraluminal pressure (IP) and longitudinal tension (LT) in small intestinal segments from M2 or M3 receptor knockout (KO) and wild-type (WT) mice. KEY RESULTS In the WT preparations, luminal distension induced a continuous rhythmic contractile activity that was characterized by synchronous rises in IP and LT, occurring periodically at a constant interval. Tetrodotoxin completely abolished the response, whereas atropine either abolished or attenuated it. In the majority of the M2 KO preparations, however, no rhythmic activity was observed in response to the luminal distention, even though networks of enteric neurons and interstitial cells of Cajal (ICC) seemed to be intact. Where rhythmic activity did occur in M2 KO preparations, it was atropine resistant. In the M3 KO preparations, the IP and LT were synchronously changed by the luminal distention, but the changes occurred at irregular intervals. The W/W(v) mutant preparations, which lack ICC in the myenteric plexus (ICC-MY), showed results similar to those of the M3 KO preparations. In some of the M2 /M3 double-KO preparations, rhythmic activity was not observed, but in the others, an atropine-resistant rhythmicity appeared. CONCLUSIONS & INFERENCES These results suggest that M2 and M3 muscarinic receptors differentially regulate the intestinal motor activity: M2 receptors play an essential role in the generation of rhythmic motor activity, and M3 receptors have a modulatory role in controlling the periodicity of the rhythmic activity together with the ICC-MY.

Abstract
BACKGROUND Scant evidence has been reported on the evaluation of quality-of-life (QOL) in patients who had undergone surgical treatment due to pelvic floor prolapse including cystocele. The aim of this study is to evaluate the impact of surgical intervention on patients' QOL before and after surgery. METHODS Between 1997 and 2007, 135 patients (median age: 66.6 years) with pelvic floor prolapse including cystocele underwent bladder neck suspension with anterior/posterior colporrhaphy. The follow-up period was 39.6 months. Seventy-two patients (53 %) had urinary incontinence. The cystocele was graded as mild (grade 2), moderate (grade 3), and severe (grade 4) in 35, 60, and 40, respectively, according to the Baden-Walker classification. A urodynamic study was performed in 69 patients (51 %) who had obstructive symptoms with 100 ml or more of postvoid residual urine. Postoperative QOL was longitudinally assessed in 114 patients by scoring three disease-specific items (sensation of vaginal bulging, obstructive symptoms, urinary incontinence), and one overall health-related QOL (HR-QOL), and compared with corresponding baseline scores. RESULTS A longitudinal study demonstrated that a significant improvement in these symptoms was sustained at a median follow-up of 62.2 months. HR-QOL was significantly associated with vitality assessed by SF 36 (p = 0.036). Multivariate analysis revealed that update urinary incontinence, pre-operative HR-QOL was independent prognostic factors for predicting postoperative patient's satisfaction. CONCLUSIONS Although surgical repair of pelvic floor prolapse can achieve acceptable results with intermediate-term durability as well as improving the QOL, preoperative patients' HR-QOL may be considered in the decision making process for treatment.

Abstract
BACKGROUND Ras association domain family 1A (RASSF1A) is a tumor suppressor that regulates the cell cycle, apoptosis, and microtubule stability. The association between the methylation levels of RASSF1A and the prognosis of clear-cell renal cell carcinoma (CCRCC) remains unclear. Therefore, we investigated this relationship to determine the prognostic value of RASSF1A methylation levels for CCRCC. PATIENTS AND METHODS The study comprised 179 Japanese patients who underwent radical or partial nephrectomy for CCRCC. The methylation level of 5' CpG islands in the RASSF1A was evaluated using combined bisulfite restriction analysis and bisulfite sequencing. RESULTS High levels of methylation in the RASSF1A promoter were significantly more frequent in grade 3 compared with grade 1 or 2 tumors (P = 0.028) and in patients with stage III or IV compared with patients with stage I or II (P = 0.043). Patients with high methylation levels had a significantly less favorable prognosis compared with those with low methylation levels (P = 0.040). Higher methylation levels were independently associated with a poor prognosis following multivariate analysis (P = 0.0053). CONCLUSION These results indicate that quantitative promoter methylation levels of the RASSF1A gene may be a useful marker to predict the prognosis of CCRCC.

Abstract
BACKGROUND AND PURPOSE The functional roles of M(2) and M(3) muscarinic receptors in neurogenic cholinergic contractions in gastrointestinal tracts remain to be elucidated. To address this issue, we studied cholinergic nerve-induced contractions in the ileum using mutant mice lacking M(2) or M(3) receptor subtypes. EXPERIMENTAL APPROACH Contractile responses to transmural electrical (TE) stimulation were isometrically recorded in ileal segments from M(2)-knockout (KO), M(3)-KO, M(2)/M(3)-double KO, and wild-type mice. KEY RESULTS TE stimulation at 2-50 Hz frequency-dependently evoked a fast, brief contraction followed by a slower, longer one in wild-type, M(2)-KO or M(3)-KO mouse preparations. Tetrodotoxin blocked both the initial and later contractions, while atropine only inhibited the initial contractions. The initial cholinergic contractions were significantly greater in wild-type than M(2)-KO or M(3)-KO mice; the respective mean amplitudes at 50 Hz were 91, 74 and 68 % of 70mM K(+)-induced contraction. Pretreatment with pertussis toxin blocked the cholinergic contractions in M(3)-KO but not in M(2)-KO mice. Cholinergic contractions also remained in wild-type preparations, but their sizes were reduced by 20-30 % at 10-50 Hz. In M(2)/M(3)-double KO mice, TE stimulation evoked only slow, noncholinergic contractions, which were significantly greater in sizes than in any of the other three mouse strains. CONCLUSION AND IMPLICATIONS These results demonstrate that M(2) and M(3) receptors participate in mediating cholinergic contractions in mouse ileum with the latter receptors assuming a greater role. Our data also suggest that the lack of both M(2) and M(3) receptors causes upregulation of noncholinergic excitatory innervation of the gut smooth muscle.

Abstract
DNA repair enzymes repair DNA damaged by platinum agents and ionising radiation. Single nucleotide polymorphisms (SNPs) in DNA repair genes modulate the repair capacity and might affect response and prognosis following platinum-based chemoradiotherapy (CRT). We investigated associations between the functional SNPs in DNA repair genes and response and survival in muscle-invasive bladder cancer patients treated with CRT to determine the predictive value of the SNPs in patient selection for bladder conservation therapy. The study group comprised 78 patients who underwent CRT for transitional cell carcinoma of the bladder. Single nucleotide polymorphisms in xeroderma pigmentosum complementation groups C (Lys939Gln, A/C), D (XPD; Lys751Gln, A/C), and G (Asp1104His, G/C), and X-ray repair cross-complementing groups 1 (XRCC1; Arg399Gln, G/A) and 3 (Thr241Met, T/C) genes were genotyped. Combined genotypes with at least one variant allele in XPD or XRCC1 were significantly associated with improved cancer-specific survival compared with remaining groups (P=0.009). In multivariate analysis, only the combined XPD and XRCC1 genotypes were independently associated with cancer-specific survival (P=0.04). The association was stronger in stage T3/T4 patients (P=0.0008). These results suggest that combined XPD and XRCC1 genotypes might be prognostic factors in muscle-invasive bladder cancer patients treated with CRT.

Abstract
1 The muscarinic receptor plays a key role in the parasympathetic nervous control of various peripheral tissues including gastrointestinal tract. The neurotransmitter acetylcholine, via activating muscarinic receptors that exist in smooth muscle, produces its contraction. 2 There is the opening of cationic channels as an underlying mechanism. The opening of cationic channels results in influxes of Ca2+ via the channels into the cell and also via voltage-dependent Ca2+ channels which secondarily opened in response to the depolarization, providing an amount of Ca2+ for activation of the contractile proteins. 3 Electrophysiological and pharmacological studies have shown that the cationic channels as well as muscarinic receptors exist in many visceral smooth muscle cells. However, the activation mechanisms of the cationic channels are still unclear. 4 In this article, we summarize the current knowledge of the muscarinic receptor-operated cationic channels, focusing on the receptor subtype, G protein and other signalling molecules that are involved in activation of these channels and on the molecular characteristics of the channel. This will improve strategies aimed at developing new selective pharmacological agents and understanding the activation mechanism and functions of these channels in physiological systems.

Abstract
4579 Background: The combination chemotherapy of paclitaxel, ifosfamide, and nedaplatin (PIN regimen) has been shown to be effective in patients with advanced urothelial cancer. The aim of this presentation is to evaluate long-term followup outcomes in patients who had treated with standard cisplatin-based chemotherapy. Methods: The PIN regimen consisted of paclitaxel 175 mg/m2 on day 1, ifosfamide 4.5 g/m2 divided over days 1, 2 and 3, and nedaplatin 70 mg/m2 on day 1; PIN was given every 28 days. The doses of nedaplatin and ifosfamide were reduced according to the impairment of renal function (24h CCr) just before starting each cycle of PIN therapy Results: Thirty two patients who had previously undergone cisplatin-based chemotherapy were entered onto the study (median age, 66 years; median performance status, 1, median 24h CCr, 62ml/min [29–119ml/min] ). Metastatic sites at study entry included the lymph nodes (24), lung (6), bone (5), primary (5), soft tissue (3), and liver (2). Among the 32 assessable patients, there were 5 CRs (16%) and 19 PRs (59%) for an overall RR of 75 % (95% confidence interval [CI], 59–91 %). The median time to progression was 8 months (range, 0–50+ months) and the median survival was 22 months (range, 4–52+ months). Twelve patients received the full dose of PIN combination (median 5 cycles) and 20 patients required dose reduction (median 3 cycles). Nine of 12 (75%) patients who were treated with the full-dose PIN combination obtained a CR or PR, as did 15 of 20 (75%) patients who required dose reduction. Grades 3 and 4 neutropenia occurred in all patients. Febrile neutropenia occurred in 8 (25%) patients. Grades 3 and 4 thrombocytopenia occurred in 8 (25%) patients. Grades 3 and 4 anemia was observed in 6 (19%) patients. Grade 3 neuropathy occurred in 1 (3%) patient, who could not continue to receive additional cycles of PIN combination after 3 cycles. No patient experienced renal failure. There were no treatment-related deaths. Conclusions: The PIN combination was highly active and tolerable in patients who had previously treated with cisplatin-based chemotherapy, and might be suitable for those with mild to moderate renal insufficiency. No significant financial relationships to disclose.

Macrophage-derived cytokine and nitric oxide profiles in type I and type II diabetes mellitus: effect of thymoquinone. Acta Diabetol 2005; 42:23-30.

Abstract
Comparing macrophage-derived cytokine and nitric oxide (NO) profiles in type I and type II diabetes mellitus (DM); and determining whether thymoquinone (TQ) has any modulatory effect were the main objectives of the present study. Peritoneal macrophages have been collected from Otsuka Long-Evans Tokushima Fatty (OLETF) as a model for type II DM and its control Long-Evans Tokushima Otsuka (LETO) rats, as well as from streptozotocin (STZ)-injected LETO ones as a model for type I DM. The cells were cultured and incubated with or without TQ (10 microM) in the absence or presence of lipopolysaccharide (LPS; 1 microg/ml). The same parameters have been also assessed in sera of the used animals with or without TQ treatment (3 mg/kg) under both LPS-stimulated (10 mg/kg) and unstimulated conditions. Nitrite, IL-1beta and TNF-alpha were significantly higher in macrophage supernatants and sera of the acutely affected STZ-LETO rats either with or without LPS stimulation compared to corresponding controls. On the other hand, chronically diabetic OLETF rats' macrophage supernatants showed significant decreases of IL-1beta and TNF-alpha levels upon LPS stimulation or even without stimulation (IL-1beta); and insignificant increase in nitrite concentration, which turned significant upon LPS stimulation. Sera of these animals, however, showed significant increase in TNF-alpha level. TQ normalised the elevated nitrite and cytokine profiles both in vitro and in vivo, yet had no significant effect on the already decreased parameters in chronically affected OLETF rats. These data suggest that there is a tendency for macrophage inflammatory products to increase in acute type I and to decrease in chronic type II DM; and that TQ has the potential to normalise the elevated levels of these macrophage-derived inflammatory mediators.
