Abstract
OBJECTIVE To elucidate the relationship between frailty and lower urinary tract symptoms (LUTS). METHODS We longitudinally evaluated the temporal changes and the relationships between frailty and LUTS in 247 community-dwelling adults (45 years or older) at baseline and at a 5-year follow-up. We used the Fried phenotype (phenotype-based frailty), 5-item modified frailty index (5i-mFI; comorbidity-based frailty), and frailty discriminant score (comprehensive frailty assessment) to evaluate frailty. LUTS were evaluated using the international prostate symptom score (IPSS) and overactive bladder symptom score (OABSS). RESULTS We analyzed 247 participants with a median age of 60 years. The median IPSS and OABSS were significantly increased over the 5 years. The proportion of frail individuals did not increase significantly over the 5 years. Of the three frailty assessment tools, the 5i-mFI score significantly increased between 2014 and 2019. Multiple linear regression analyses showed that the 5i-mFI score was significantly associated with the severity of LUTS in 2014 to 5i-mFI in 2019 but not with 5i-mFI in 2014 to the severity of LUTS in 2019. CONCLUSION The effect of LUTS on frailty might be greater than the effect of frailty on LUTS. Further large-scale studies are needed to elucidate the relationship between LUTS and frailty.

Abstract
Background Testicular germ cell tumors (GCTs) are the most common type of cancer in adolescent boys and young adult men, but the age at onset has been increasing. However, little is known regarding the incidence and age of patients with testicular GCTs in Japan because the incidence there is low. Methods We retrospectively reviewed the medical records of patients with GCTs in seven hospitals between 2001 and 2021. We compared the incidences of testicular GCTs, ages at onset, pathological types (seminoma or nonseminoma), and clinical stages in patients with GCTs between the periods 2001-2010 and 2011-2021. Results We identified 193 adults (≥20 years of age) with testicular GCTs; their median age was 37 years [interquartile range (IQR), 29-47 years]. Of these patients, 87 (45.1%) were ≥40 years of age at diagnosis. The proportion of patients aged ≥40 years was significantly higher in the period 2011-2021 (54.8%) than in 2001-2010 (30.8%; P=0.001). The incidence of seminoma was significantly higher in the period 2011-2021, but clinical stage did not differ significantly between the two periods. The population-adjusted incidence among patients in their 40s was 3.4-fold higher in 2011-2021 than in 2001-2010. Conclusions The number of patients with GCTs aged ≥40 years was significantly higher in 2011-2021, even in a population-adjusted analysis. Treatment strategies need to be adapted to older testicular germ cell tumor patients.

Abstract
PURPOSE We compared the real-world efficacy and medical costs for treatment with upfront docetaxel (DOC) and abiraterone acetate (ABI) up to progression-free survival 2 (PFS2) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). METHODS This multicenter retrospective study included 340 patients with mHSPC treated with either upfront DOC or upfront ABI between October 2015 and December 2021. We compared PFS2 and medical costs between the two treatment groups. PFS2 was defined as the time from first-line therapy to progression on second-line therapy. Medical costs were estimated using the National Health Insurance drug prices in 2022 in Japan. RESULTS The upfront DOC and ABI groups included 107 and 233 patients, respectively. The incidence of metastatic castration-resistant PC progression was significantly higher in the upfront DOC group compared with the incidence in the upfront ABI group. However, no significant differences in PFS2 were observed between the two treatment groups. Monthly medical costs per patient were significantly higher in the upfront ABI group ($3453) compared with the costs in the upfront DOC group ($1239, P < 0.001). The cost differences were significantly influenced by differences in the length of androgen deprivation therapy monotherapy (DOC group, 13.4 months vs. ABI group, 0.0 months). CONCLUSIONS We observed a significant cost benefit in the upfront DOC group in Japanese real-world practice, while the PFS2 rates were similar between the groups. Upfront DOC was a more cost-effective option for men with mHSPC who were eligible for toxic chemotherapy.

Abstract
PURPOSE To assess the influence of gut microbiome on overactive bladder (OAB) symptoms progression. METHODS This was a 3-year longitudinal study, Hirosaki in Japan. We assessed OAB symptoms and reviewed the medication records of each subject in 2016. We extracted 16S rRNA genes from fecal samples and analyzed gut microbiomes via next-generation sequencing. We evaluated the changes in urinary urgency (UU) and/or urgent urinary incontinence (UUI) from 2016 to 2019. We defined UU/UUI-progression as exacerbation of UU and/or UUI. We compared the clinical backgrounds and microbiota structure between UU/UUI-progression subjects and non-progression (controls). We assessed the impact of gut microbiome on the UU/UUI-progression via multivariate logistic regression analyses. RESULTS Of 669 subjects, 126 were UU/UUI-progression subjects. These subjects had a higher age and prevalence of proton pump inhibitor (PPI) use (14% vs. 5.4%, P = 0.003), irritable bowel syndrome, sleep disturbance, and metabolic syndrome than those without. We found the different microbiota structures between subjects with UU/UUI-progression and those without. A higher relative abundance of genus Streptococcus (harmful bacterial genus for human health) appeared in UU/UUI-progression subjects (3.8% vs. 2.3%, P < 0.001). Multivariate analysis revealed that age ≥ 65 years, current smoking, sleep disturbance, metabolic syndrome, and genus Streptococcus (Odds ratio: 1.05, P = 0.029) were independent risk factors for UU/UUI-progression. PPI use turned to be a significant risk factor on a multivariate analysis without including genus Streptococcus. CONCLUSIONS Gut microbiome might be associated with a risk for OAB symptoms progression. PPI use might cause gut dysbiosis and increase this risk.

Abstract
The OPERA experiment was designed to discover the vτ appearance in a vμ beam, due to neutrino oscillations. The detector, located in the underground Gran Sasso Laboratory, consisted of a nuclear photographic emulsion/lead target with a mass of about 1.25 kt, complemented by electronic detectors. It was exposed from 2008 to 2012 to the CNGS beam: an almost pure vμ beam with a baseline of 730 km, collecting a total of 1.8·1020 protons on target. The OPERA Collaboration eventually assessed the discovery of vμ→vτ oscillations with a statistical significance of 6.1 σ by observing ten vτ CC interaction candidates. These events have been published on the Open Data Portal at CERN. This paper provides a detailed description of the vτ data sample to make it usable by the whole community.

Abstract
Abstract
Cellular senescence entails an irreversible growth arrest and a pro-inflammatory secretory phenotype, which contributes to aging-associated disorders such as atherosclerosis and diabetes, however, underlying mechanisms are largely unknown. In this study, we identified a novel protein, senescence-associated glycoprotein (SAGP), as a biomarker of cellular senescence and we also found that elimination of senescent cells targeting SAGP attenuated aging-associated disorders such as atherosclerosis, diabetes and frailty.
First, we identified that SAGP as a senescent marker by microarray analysis of senescent human endothelial cells compared with young endothelial cells. The expression of SAGP was significantly increased in the aorta of chronological aging mice and ApoE-knockout mice. Then we measured SAGP expression in the patients registered in our hospital and found that mean SAGP expression was significantly higher in patients with atherosclerotic diseases compared to patients without atherosclerotic diseases. These data suggest that SAGP would become the novel marker of cellular senescence and/or aging-associated disorders.
We found SAGP co-localized with lysosome and bound to V-ATPase, proton pump in the acid organelles such as lysosome. The electron microscopy analysis revealed that the dysfunctional lysosomes were accumulated in SAGP knockdown endothelial cell. The genetic deletion of SAGP resulted in the increase of lysosomal pH and the suppression of mitochondrial autophagy, mitophagy. And this associated with the high level of mitochondrial reactive oxygen species (ROS) and promoted premature senescence in human endothelial cells. These data suggest that SAGP was induced by the lysosomal stress in the senescent cells to protects senescent cells by maintaining the lysosomal homeostasis.
Recently, it is reported that elimination of senescent cells (senolysis) reversibly improved pathological aging phenotypes and also extended the lifespan. We established senolytic therapy targeting SAGP. We generated SAGP-DTR (diphtheria toxin receptor) transgenic mice, in which we could eliminate the SAGP- positive senescent cells using DT (diphtheria toxin). We found elimination of SAGP positive senescent cells significantly reduced the atherosclerotic plaque burden in the aorta of ApoE-KO mice and improved the glucose metabolism of dietary obese mice, indicating that SAGP could be a useful target for senolytic therapy. For clinical implication, we then developed a cytotoxic vaccine targeting SAGP. Treatment with SAGP vaccine successfully eliminated SAGP positive senescent cells and attenuated atherosclerosis and metabolic dysfunction. Surprisingly, administration of SAGP vaccine to Zmpste24-KO mice, premature aging mice, extended the lifespan. These data indicate that targeting SAGP-positive cells could be a novel strategy for senolytic therapy.

Abstract
Abstract
Background/Introduction
Mitochondria are dynamic regulators of cellular metabolism and homeostasis. The dysfunction of mitochondria has long been considered a major contributor to aging and age-related diseases. The prognosis of severe heart failure is still unacceptably poor and it is urgent to establish new therapies for this critical condition. Some patients with heart failure do not respond to established multidisciplinary treatment and they are classified as “non-responders”. The outcome is especially poor for non-responders, and underlying mechanisms are largely unknown.
Purpose
Studies indicate mitochondrial dysfunction has causal roles for metabolic remodeling in the failing heart, but underlying mechanisms remain to be explored. This study tried to elucidate the role of Mitofusin-1 in a failing heart.
Methods
We examined twenty-two heart failure patients who underwent endomyocardial biopsy of intraventricular septum. Patients were classified as non-responders when their left-ventricular (LV) ejection fraction did not show more than 10% improvement at remote phase after biopsy. Fourteen patients were classified as responders, and eight as non-responders. Electron microscopy, quantitative PCR, and immunofluorescence studies were performed to explore the biological processes or molecules involved in failure to respond. In addition to studies with cardiac tissue specific knockout mice, we also conducted functional in-vitro studies with neonatal rat ventricular myocytes.
Results
Twenty-two patients with IDCM who underwent endomyocardial biopsy were enrolled in this study, including 14 responders and 8 non-responders. Transmission electron microscopy (EM) showed a significant reduction in mitochondrial size in cardiomyocytes of non-responders compared to responders. Quantitative PCR revealed that transcript of mitochondrial fusion protein, Mitofusin-1, was significantly reduced in non-responders. Studies with neonatal rat ventricular myocytes (NRVMs) indicated that the beta-1 adrenergic receptor-mediated signaling pathway negatively regulates Mitofusin-1 expression. Suppression of Mitofusin-1 resulted in a significant reduction in mitochondrial respiration of NRVMs. We generated left ventricular pressure overload model with thoracic aortic constriction (TAC) in cardiac specific Mitofusin-1 knockout model (c-Mfn1 KO). Systolic function was reduced in c-Mfn1 KO mice, and EM study showed an increase in dysfunctional mitochondria in the KO group subjected to TAC.
Conclusions
Mitofusin-1 becomes a biomarker for non-responders with heart failure. In addition, our results suggest that therapies targeting mitochondrial dynamics and homeostasis would become next generation therapy for severe heart failure patients.

Abstract
We describe the clinical and histological characteristics of stromal-type nephroblastomas that developed in two hedgehogs (Atelerix albiventris). In case 1, the tumour was composed of a proliferation of anaplastic stromal cells with ductal structures resembling the epithelium of nephroblastoma. In case 2, spindle-shaped cells that were somewhat larger than nephroblasts were frequently seen surrounding the cell cluster, and there was proliferation of stromal cells with collagen fibres at the periphery. Immunohistochemically, the tumour cells labelled weakly to strongly for the nephroblast marker Wilms' tumour-1 and were positive for Ki67 with rates of 5% and 10% for cases 1 and 2, respectively. Based on the above, the diagnosis was of stromal-type nephroblastoma with anaplasia in case 1 and without anaplasia in case 2. Our findings suggest that stromal-type nephroblastomas arise in adult hedgehogs and are clinically benign, and that histological anaplasia does not affect the prognosis.

Abstract
We describe a black-tailed prairie dog (Cynomys ludovicianus) with a benign biphasic nodular tumour that recurred as a malignant biphasic tumour at the same site 2 years after resection. Both tumours were biphasic with regard to the glandular epithelium and basal cells and contained little of the mucus, cartilage or fibrous tissue that characterize pleomorphic adenoma and carcinoma ex-pleomorphic adenoma. Both the first and second tumours exhibited histopathological features similar to those exhibited by human basal cell adenoma and adenocarcinoma, respectively. Both were resected and the animal was alive with no recurrence or metastasis at the time of writing, 9 months after the second surgery.

Abstract
The OPERA experiment was designed to study ν_{μ}→ν_{τ} oscillations in the appearance mode in the CERN to Gran Sasso Neutrino beam (CNGS). In this Letter, we report the final analysis of the full data sample collected between 2008 and 2012, corresponding to 17.97×10^{19} protons on target. Selection criteria looser than in previous analyses have produced ten ν_{τ} candidate events, thus reducing the statistical uncertainty in the measurement of the oscillation parameters and of ν_{τ} properties. A multivariate approach for event identification has been applied to the candidate events and the discovery of ν_{τ} appearance is confirmed with an improved significance level of 6.1σ. |Δm_{32}^{2}| has been measured, in appearance mode, with an accuracy of 20%. The measurement of the ν_{τ} charged-current cross section, for the first time with a negligible contamination from ν[over ¯]_{τ}, and the first direct evidence for the ν_{τ} lepton number are also reported.

Abstract
The reported prevalence of sarcopenia has shown a wide range, crucially based on the diagnostic criteria and setting. This cross-sectional study evaluated the prevalence of sarcopenia and sought to identify factors associated with sarcopenia on admission in a specialized geriatric rehabilitation setting based on the newly developed the Asian Working Group for Sarcopenia algorithm. Among 87 participants (mean age, 76.05 ± 7.57 years), 35 (40.2%) were classified as showing sarcopenia on admission. Prevalence was high, particularly among participants ≥80 years old, with tendencies toward lower body mass index, smoking habit, lower cognitive function, and greater functional impairment compared with the non-sarcopenic group. Identification of sarcopenia in elderly patients before rehabilitation and consideration of risk factors may prove helpful in achieving rehabilitation outcomes.

Abstract
Aggressive periodontitis (AgP) is characterized by rapid alveolar bone destruction and tooth loss early in life, and its etiology remains unclear. To explore the genetic risk factors of AgP, we performed genome-wide single-nucleotide polymorphism genotyping for identity-by-descent mapping and identified 32 distinct candidate loci, followed by whole exome sequencing with 2 pedigrees of AgP consisting of 3 cases and 1 control in 1 family and 2 sibling cases in the other. After variant filtering procedures and validation by targeted Sanger sequencing, we identified 2 missense mutations at 16q12 in NOD2 (p.Ala110Thr and p.Arg311Trp), which encodes nucleotide-binding oligomerization domain protein 2. We further examined 94 genetically unrelated AgP patients by targeted sequencing of NOD2 and found that 2 patients among them also carried the p.Arg311Trp variant. Furthermore, we found 3 additional missense mutations in this gene (p.His370Tyr, p.Arg459Cys, and p.Ala868Thr). These mutations either had not been previously observed or are extremely rare (frequency <0.001) in Asian populations. NOD2 plays a crucial role in innate immunity as an intracellular receptor initiating nuclear factor κB-dependent and mitogen-activated protein kinase-dependent gene transcription. These results demonstrated NOD2 as a novel gene involved in AgP.

Abstract
OBJECTIVE Halitosis is caused by volatile sulphur compounds including methyl mercaptan (CH3 SH) in the oral cavity and is a serious problem that limits interpersonal social communication. The aim of study was to evaluate the effects of reuterin-related compounds (RRCs) on halitosis-related periodontopathic bacteria in vitro. MATERIALS AND METHODS RRC-01, RRC-02 and RRC-03 (32 and 64 μg ml-1 ) in culture media containing Fusobacterium nucleatum JCM8523 and Porphyromonas gingivalis ATCC33277 were used. The effects of RRCs on CH3 SH production and detectable odour by F. nucleatum and P. gingivalis were examined by CH3 SH production assay and organoleptic test, respectively. The number of bacterial cells was also measured using an ATP assay. In P. gingivalis treated with RRCs, the expression of mgl gene, which is responsible for CH3 SH production, was examined by qRT-PCR. RESULTS CH3 SH production and the score of detectable odour from F. nucleatum and P. gingivalis culture media containing RRCs were significantly lower than that without RRCs (P < 0.05). The expression of mgl gene in P. gingivalis was significantly downregulated by RRC-01 (P < 0.01), but not by RRC-02 or RRC-03. CONCLUSIONS RRCs are potent oral care products for preventing halitosis via reducing CH3 SH production.

Abstract
L10 MnAl, which is a nonequilibrium ferromagnetic phase, is fabricated successfully with various compositions via high-pressure synthesis. The L10 phase is observed at pressures higher than 5 GPa, indicating that the volume effect is crucial for the stabilization of this phase. The employed synthesis route does not require a Mn-rich ε-phase, which has conventionally been used as the precursor compound. This allows for the synthesis of the L10 phase with a near-stoichiometric composition. In addition to variations in the composition in terms of the Mn/Al ratio, the axial ratio (c/a) as well as the ordering parameter (S) are modified systematically, with the maximum c/a and S values corresponding to the stoichiometric composition. With this structural change, the highest coercive force is also observed at the stoichiometric composition.

Abstract
Cell entry of herpes simplex virus type 2 (HSV-2) requires the interaction of viral glycoprotein D (gD) with the receptor nectin-1 and herpesvirus entry mediator (HVEM). In addition, it is known that nectin-2 is also functional as a receptor for HSV-2, although the binding to the gD is weak. To examine an antiviral potential of a soluble form of human nectin-2 (hNectin-2Ig), transfected Vero cells expressing the entire ectodomain of nectin-2 fused to the Fc portion of human IgG were established. Specific binding of hNectin-2Ig to HSV-2 gD was confirmed by ELISA. Competitive ELISA demonstrated that accumulation of hNectin-2Ig in transfected cells increased significantly in a cell culture time dependent manner. Viral growth of several HSV-2 strains was significantly inhibited in the transfected cells that were cultured for 72 hr compared with control Vero cells, but not in cells that were cultured for 24 hr. These results indicate that accumulation of a soluble form of nectin-2 is required for exerting the resistance against HSV-2 infection.

Abstract
Among the intestinal tumors of hematopoietic cell origin, lymphoma is the most common in the dog. Herein, we characterized the clinical and pathologic features of 11 dogs (average age, 10.6 ± 2.5 years) with T-cell lymphoma of the intestinal tract with eosinophil infiltrates. No sex predominance was apparent. All had localized tumor masses in the small intestine. Grossly, the intestinal wall was thickened, and the lumen of the affected intestine was usually narrowed. Microscopically, we observed transmural diffuse invasion of round to pleomorphic tumor cells. Tumor cells showed varying morphology, from scanty to abundant cytoplasm, and round to ovoid nuclei with scattered to dense chromatin. In seven of the dogs, tumor cells had infiltrated into the epithelium. All showed infiltration of eosinophils and all 11 tumors had a T-cell phenotype (CD3+,CD79-). Only one tumor stained positive for the mast cell marker c-kit and none was positive for mast cell tryptase. We did not observe ultrastructurally apparent granules in any of the tumor cells. These results suggest that, in dogs, T-cell lymphomas of intestinal origin resemble mast cell tumors of intestinal origin with respect to cell structure and eosinophil infiltration. Therefore, in the absence of epitheliotropism, it is difficult to confirm the differential diagnosis without immunostaining for mast cell and lymphocyte markers, including mast cell tryptase, c-kit, CD3, and CD79.

Abstract
Mast cell tumors (MCTs) of gastrointestinal origin that had been surgically removed from 39 dogs were examined to evaluate their pathologic features. Miniature breeds, especially Maltese, were most frequently affected. The average age of affected dogs was 9.7 ± 2.6 years. No sex difference was apparent. The most frequently affected sites were in the upper digestive tract, and the prognosis was very poor. Grossly, the gastrointestinal wall was prominently thickened, and the lumen of the affected gut was usually narrowed. Microscopically, there was diffuse transmural invasion of round to pleomorphic tumor cells. Tumor cells had moderate to abundant cytoplasm, round to ovoid nuclei with scattered chromatin, and mitotic figures. Fibrous stroma was observed in about half of the tumors. There was variable infiltration of eosinophils. In all tumors, cytoplasmic granules showed weak metachromasia, but the number of granules was very small. Immunohistochemical staining for c-kit and mast cell tryptase was positive in 77% and 62% of tumors, respectively. All tumors were positive for at least two of these markers. Immunohistochemical staining for p53 was positive in 13% of the tumors. Reactivity for staining markers and p53 was unrelated to cell pleomorphism, vessel invasion, or survival time. Gastrointestinal MCTs have histologic and immunohistochemical features completely different from those of other primary or metastatic gastrointestinal tumors. The combination of immunostaining for mast cell tryptase and c-kit and histochemical staining for metachromasia appears to be a powerful tool for the diagnosis of gastrointestinal MCTs.

Abstract
OBJECTIVE/BACKGROUND Recently, the indications for thoracic endovascular aortic repair (TEVAR) have been expanding, and the applicability of TEVAR for acute type B aortic dissection (TBAD) is proposed with regard to the high mortality of open surgery for chronic TBAD. TEVAR in the acute phase may lead to remodeling of the false lumen (FL), but it is controversial whether it completely resolves the aortic expansion in the chronic phase. In this study, operative results and the relationship between FL status and the time before surgical intervention were retrospectively analyzed. METHODS From January 2008 to September 2013, 234 patients underwent open surgery for chronic TBAD. Most patients were on left heart bypass. By considering Japanese aortic disease treatment guidelines and the smaller physique of Japanese patients, operative indications were aneurysm >50 mm in diameter or rapid aneurysm enlargement of >5 mm in a 6 month period. RESULTS In 180 cases, the FL was patent. The mean interval between onset of TBAD and operation was 61 ± 54 months. There was no significant difference between patients in the patent FL group and those in the thrombosed FL group (p = .44). Mean ratio of FL diameter to maximum aortic diameter (FL/AD) was 0.64 ± 0.21. There was no correlation between FL and AD before the operation (r = .12). Descending thoracic aortic replacement (DTAR) was performed in 127 cases and thoracic ascending aortic replacement (TAAR) in 107 cases (Crawford type I, n = 9; Crawford type II, n = 65; Crawford type III and IV, n = 22, respectively; Safi type V, n = 11). The overall operative mortality was 6.8%: 3.9% (5/127) for DTAR and 10.3% (11/107) for TAAR. The three year survival was 86.7, and the freedom from re-intervention rate was 97.0%. CONCLUSION Enlargement of uncomplicated TBAD in the chronic phase was poorly related to FL status and the results of open repair have improved. However, further prospective study is necessary.

Abstract
The OPERA experiment was designed to search for ν_{μ}→ν_{τ} oscillations in appearance mode, i.e., by detecting the τ leptons produced in charged current ν_{τ} interactions. The experiment took data from 2008 to 2012 in the CERN Neutrinos to Gran Sasso beam. The observation of the ν_{μ}→ν_{τ} appearance, achieved with four candidate events in a subsample of the data, was previously reported. In this Letter, a fifth ν_{τ} candidate event, found in an enlarged data sample, is described. Together with a further reduction of the expected background, the candidate events detected so far allow us to assess the discovery of ν_{μ}→ν_{τ} oscillations in appearance mode with a significance larger than 5σ.

Abstract
The gene for an alkaline endoglucanase from the alkalophilic Bacillus sp. KSM-64 was cloned into the HindIII site of pBR322 and expressed in Escherichia coli HB101. The nucleotide sequence of a 4.1-kb region of the HindIII insert had two open reading frames, ORF-1 and ORF-2. The protein deduced from ORF-1 was composed of 244 amino acids with an M(r) of 27,865. Subcloning analysis proved that the alkaline endoglucanase was encoded by ORF-2 (822 amino acids with an M(r) of 91,040). Upstream from ORF-2, there were three consensus like sequences of the sigma A-type promoter of Bacillus subtilis, a putative Shine-Dalgarno sequence (AGGAGGT), and a catabolite repression operator-like sequence (TGTAAGCGGTTAACC). The HindIII insert was subcloned into a shuttle vector, pHY300PLK, and the encoded alkaline endoglucanase gene was highly expressed both in E. coli and B. subtilis. One of the three promoter-like sequences in ORF-2 could be suitable for high levels of enzyme expression in both host organisms.

Abstract
Catalytic lectins (leczymes) of frog eggs are sialic acid-binding lectins that have intrinsic RNase activity. They inhibit tumor cell proliferation in vitro and in vivo, although their cytotoxic mechanism remains unclear. RNase A has no tumoricidal activity. It is hypothesized that leczymes bind to cell surface sialoglycoconjugate receptors, enter the cell, and subsequently degrade RNA. In order to investigate the cytotoxic mechanism of cSBL, a leczyme from Rana catesbeiana eggs, we established cSBL-resistant clone RC-150 from mouse leukemia P388 cells. cSBL-treated P388 cells showed extensive RNA degradation over the course of 1 h, whereas cSBL-treated RC-150 cells showed no RNA degradation even over the course of 24 h. Treatment of P388 cells with cSBL led to decreased concentration of intracellular Ca2+, decreased protein kinase A activity, and increased protein kinase G activity. Incubation with cSBL decreased glutathione levels and enhanced glutathione-S-transferase (GST) activity in P388 cells, but had no effect on RC-150 cells. We conclude that cSBL-specific degradation of RNA occurs in cSBL-sensitive tumor cells, that cSBL leads to alteration of signal transduction and an intracellular protein kinase cascade reaction, and that internalized cSBL is detoxified by GST or thioltransferase. Our findings support a bifunctional model in which a leczyme is both an adhesive protein (binding to sialoglycoconjugates) and an enzyme (displaying RNnase activity).

Abstract
BACKGROUND Eltrombopag is an oral, non-peptide thrombopoietin receptor agonist that has shown efficacy and safety in chronic immune thrombocytopenia (ITP). However, ethnic differences in eltrombopag exposure have been reported: area under the curve exposure to eltrombopag was 87% greater among ITP patients of East Asian descent than among ITP patients of non-East Asian ITP descent. OBJECTIVES To evaluate the efficacy and safety of eltrombopag by using, in Japanese ITP patients, lower starting (12.5 mg) and maximum (50 mg) doses of eltrombopag than the standard starting (50 mg) and maximum (75 mg) doses approved in the USA and Europe. PATIENTS We examined 23 Japanese patients with previously treated chronic ITP with a platelet count of < 30,000 μL(-1) in a multicenter study comprising a randomized, double-blind, placebo-controlled phase for 6-week evaluation (15 eltrombopag, and eight placebo) and an open-label phase for 6-month evaluation (23 eltrombopag). RESULTS AND CONCLUSIONS The response rate (platelet count of ≥ 50,000 μL(-1) ) at week 6 of the 6-week double-blind phase was 60% in eltrombopag-treated patients and 0% in placebo-treated patients. Ten of 23 patients (43.5%) responded for ≥ 75% of predefined assessment visits during the 6-month open-label phase. Notably, 22% (5/23) of patients responded to 12.5 mg of eltrombopag, which was administered within the first 3 weeks of eltrombopag treatment. Bleeding decreased with eltrombopag treatment as compared with baseline. Eltrombopag was generally well tolerated; one patient experienced a transient ischemic attack on day 9. Eltrombopag (12.5-50 mg) is effective for the management of Japanese patients with chronic ITP (NCT00540423).

Abstract
Although mesenchymal stem cells (MSCs) play pivotal supportive roles in hematopoiesis, how they interact with hematopoietic stem cells (HSCs) is not well understood. We investigated the interaction between HSCs and surrogate MSCs (C3H10T1/2 stromal cells), focusing on the molecular events induced by cell contact of these bipartite populations. C3H10T1/2 is a mesenchymal stromal cell line that can be induced to differentiate into preadipocytes (A54) and myoblasts (M1601). The stromal cell derivatives were cocultured with murine HSCs (Lineage(-)Sca1(+)), and gene expression profiles in stromal cells and HSCs were compared before and after the coculture. HSCs gave rise to cobblestone areas only on A54 cells, with ninefold more progenitors than on M1601 or undifferentiated C3H10T1/2 cells. Microarray-based screening and a quantitative reverse transcriptase directed-polymerase chain reaction showed that the levels of Notch ligands (Jagged1 and Delta-like 3) were increased in A54 cells upon interaction with HSCs. On the other hand, the expression of Notch1 and Hes1 was upregulated in the HSCs cocultured with A54 cells. A transwell assay revealed that the reciprocal upregulation was dependent on cell-to-cell contact. The result suggested that in the hematopoietic niche, HSCs help MSCs to produce Notch ligands, and in turn, MSCs help HSCs to express Notch receptor. Such a reciprocal upregulation would reinforce the downstream signaling to determine the fate of hematopoietic cell lineage. Clarification of the initiating events on cell contact should lead to the identification of specific molecular targets to facilitate HSC engraftment in transplantation therapy.

Abstract
Hepatoblastomas are neoplasms that originate from putative pluripotential stem cells of the liver. A hepatic mass from an 8-year-old Abyssinian cat was composed of cords and sheets of neoplastic cells, with scattered rosettes and small ductal structures. Most neoplastic cells had a pale eosinophilic cytoplasm and a round to ovoid nucleus. The tumor also had short spindle cells with an oval nucleus. Immunohistochemically, neoplastic cells were weakly positive for embryonic hepatocellular markers, such as alpha-fetoprotein and cytokeratin (CK) 8/18, but negative for the hepatocellular marker Hepatocyte Paraffin 1. The cells were also positive for CD56/neural cell adhesion molecule and for the biliary epithelial markers CK 7, CK 8/18, CK CAM5.2, and vimentin, but negative for CK 20. Some neoplastic cells expressed neuroectodermal or neuroendocrine markers, such as protein gene product 9.5 and synaptophysin, but were negative for chromogranin A and not argyrophilic by the Grimelius technique. The cat died soon after the biopsy without clinical improvement.
