Abstract
OBJECTIVE The human adrenal cortex comprises three functionally and structurally distinct layers that produce layer-specific steroid hormones. With aging, the human adrenal cortex undergoes functional and structural alteration or "adrenal aging", leading to the unbalanced production of steroid hormones. Given the marked species differences in adrenal biology, the underlying mechanisms of human adrenal aging have not been sufficiently studied. This study was designed to elucidate the mechanisms linking the functional and structural alterations of the human adrenal cortex. METHODS We conducted single-cell RNA sequencing and spatial transcriptomics analysis of the aged human adrenal cortex. RESULTS The data of this study suggest that the layer-specific alterations of multiple signaling pathways underlie the abnormal layered structure and layer-specific changes in steroidogenic cells. We also highlighted that macrophages mediate age-related adrenocortical cell inflammation and senescence. CONCLUSIONS This study is the first detailed analysis of the aged human adrenal cortex at single-cell resolution and helps to elucidate the mechanism of human adrenal aging, thereby leading to a better understanding of the pathophysiology of age-related disorders associated with adrenal aging.

Abstract
BACKGROUND The human adrenal cortex consists of three functionally and structurally distinct layers; zona glomerulosa, zona fasciculata (zF), and zona reticularis (zR), and produces adrenal steroid hormones in a layer-specific manner; aldosterone, cortisol, and adrenal androgens, respectively. Cortisol-producing adenomas (CPAs) occur mostly as a result of somatic mutations associated with the protein kinase A pathway. However, how CPAs develop after adrenocortical cells acquire genetic mutations, remains poorly understood. METHODS We conducted integrated approaches combining the detailed histopathologic studies with genetic, RNA-sequencing, and spatially resolved transcriptome (SRT) analyses for the adrenal cortices adjacent to human adrenocortical tumours. FINDINGS Histopathological analysis revealed an adrenocortical nodular structure that exhibits the two-layered zF- and zR-like structure. The nodular structures harbour GNAS somatic mutations, known as a driver mutation of CPAs, and confer cell proliferative and autonomous steroidogenic capacities, which we termed steroids-producing nodules (SPNs). RNA-sequencing coupled with SRT analysis suggests that the expansion of the zF-like structure contributes to the formation of CPAs, whereas the zR-like structure is characterised by a macrophage-mediated immune response. INTERPRETATION We postulate that CPAs arise from a precursor lesion, SPNs, where two distinct cell populations might contribute differently to adrenocortical tumorigenesis. Our data also provide clues to the molecular mechanisms underlying the layered structures of human adrenocortical tissues.

Abstract
Pancreatic islet inflammation plays a crucial role in the etiology of type 2 diabetes (T2D). Macrophages residing in pancreatic islets have emerged as key players in islet inflammation. Macrophages express a plethora of innate immune receptors that bind to environmental and metabolic cues and integrate these signals to trigger an inflammatory response that contributes to the development of islet inflammation. One such receptor, Dectin-2, has been identified within pancreatic islets; however, its role in glucose metabolism remains largely unknown. Here we have demonstrated that mice lacking Dectin-2 exhibit local inflammation within islets, along with impaired insulin secretion and β-cell dysfunction. Our findings indicate that these effects are mediated by proinflammatory cytokines, such as interleukin (IL)-1α and IL-6, which are secreted by macrophages that have acquired an inflammatory phenotype because of the loss of Dectin-2. This study provides novel insights into the mechanisms underlying the role of Dectin-2 in the development of islet inflammation.

Abstract
The present study investigated the role of heat shock protein 90 (HSP90) in the proliferation and survival of Babesia gibsoni in vitro. To detect the effect on the entry of B. gibsoni into host erythrocytes, the parasite was incubated with an antibody against B. gibsoni HSP90 (BgHSP90) for 24 hr. The results of this experiment demonstrated that both the incorporation of [3H]hypoxanthine into the nucleic acids of B. gibsoni and the number of parasites were not altered, indicating that an anti-BgHSP90 antibody did not directly inhibit the entry of the parasite into erythrocytes. Moreover, two HSP90 inhibitors, geldanamycin (GA) and tanespimycin (17-AAG), were used to evaluate the function of BgHSP90. GA and 17-AAG decreased both the incorporation of [3H]hypoxanthine and the number of infected erythrocytes, suggesting that BgHSP90 plays important roles in DNA synthesis and the proliferation of B. gibsoni. The effect of 17-AAG on the parasites was weaker than that of GA. Additionally, the effect of GA on the survival and superoxide generation of canine neutrophils was assessed. The survival of canine neutrophils was not affected. The superoxide generation was strongly suppressed by GA. This result indicated that GA inhibited the function of canine neutrophils. Additional studies are necessary to elucidate the role of BgHSP90 in the proliferation of the parasite.

Abstract
Atovaquone (ATV) has a growth inhibitory effect against Babesia gibsoni. The target site is considered mitochondria, as in the case of Plasmodium spp.; ATV would collapse the mitochondrial membrane potential. B. gibsoni has also reported that single nucleotide polymorphisms in cytochrome b of mitochondria are involved in ATV susceptibility. However, the details are still unknown. The study aim was to measure the mitochondrial membrane potential of B. gibsoni and evaluate the effect of ATV alone and combined with proguanil (PG) on the mitochondrial membrane potential. As a result of exposure of wild-type B. gibsoni to ATV alone, the number of cells with decreased mitochondrial membrane potential increased. When wild-type B. gibsoni was exposed to the ATV + PG combination, the peak value of mitochondrial membrane potential was larger than that when exposed to ATV alone. It was suggested that ATV alone affects the mitochondrial membrane potential of B. gibsoni, and the effect is enhanced by the combination of ATV and PG. The effect of ATV was weakened for B. gibsoni having reduced sensitivity to ATV (B. gibsoni with M121I), and the effect was not enhanced by the combination of ATV and PG. Although we still need to elucidate the mechanism of ATV and PG for B. gibsoni, these results strongly suggests that the target of ATV for B. gibsoni is also cytochrome b of mitochondria.

Abstract
Abstract
Study question
In the management of male infertility, we investigated whether urological consultation could improve the live birth rate, and who should visit urologists in the setting of IVF clinic.
Summary answer
Urologic consultation resulted in improvement of semen quality and live birth rate with more IVF use in those with adverse semen parameters.
What is known already
Male factor infertility exists in about a half of infertility couples. This accounts for about 8% in male reproductive age. Therefore, ideally every male partner of infertility couples attempting conception should have a urological evaluation. However, it is not very easy to access urologists who specialized in reproductive medicine in Japan because we have very few of such urologists. One the other hand, a certain number of couples are wasting their time during IVF failure without urological evaluation.
Study design, size, duration
This is a single-institution retrospective study. We enrolled male partners of infertility couples who visited Kameda IVF clinic Makuhari, Chiba, Japan, between May 2016 and December 2020 and followed at least one year. Live birth rate and the frequency of IVF use were investigated according to semen quality and urological consultation status. Chi-square tests and T tests were used to compare the results between groups.
Participants/materials, setting, methods
Among 2225 couples who visited Kameda IVF clinic Makuhari, 803 male partners (Group A, 36.0%) were evaluated by urologists who were specialized in male reproductive medicine. Remaining 1422 patients did not (Group B, 64.0%). Lifestyle evaluation, physical examination, semen analyses, scrotal ultrasonography, blood test including sexual hormones and zinc concentration were performed in Group A. Semen analyses and lifestyle evaluation were performed in Group B. Urological treatments were done according to factors of male infertility.
Main results and the role of chance
Semen quality was worse in Group A as compared to Group B (sperm motility, 28.5±16.9% vs. 46.0±17.0%; total sperm count, 105±108 million/mL vs. 176±155; total motile sperm count, 34±49 vs.87±98; mean±S.D.; p = 0.0001, 0.0001, 0.0001, A vs. B, respectively). After urologic consultation and managements, sperm motility was improved to 34±18% (p = 0.001). Live birth rate in groups A and B were similar (56.0% vs. 57.2%), however couples who obtained a child in Group A used IVF more often than those in Group B (70% vs. 49.9%, p < 0.001). Among those with adverse semen quality (total motile sperm count less than 15.6 million/mL, n = 472), 350 visited urologists (Group 1, 74.2%) and remaining 122 did not (Group 2, 25.8%). Live birth rate in Group 1 was significantly better than in Group 2 (65.3% vs. 54.1%, p = 0.0359). Use of IVF was significantly more frequent in Group 1 than Group 2 (79.3% vs. 63.6%, p = 0.0359) among who obtained a child. In those with better semen quality (motile sperm count >50 million, n = 900), 119 visited urologist (31.1%, Group 3) and 781 did not (Group 4). Live birth rate and the use of IVF were not different between Groups 3 and 4 (51.1% vs.60.9%; 50.4% vs. 62.9%).
Limitations, reasons for caution
This study is a single-institution, retrospective study in the setting of IVF clinic. There may be a selection bias since men first visit gynecologists. These could affect the study results.
Wider implications of the findings
In the setting of IVF clinic, urologic consultation resulted in improved semen quality and better live birth rate with the use of IVF, especially in those who have adverse semen parameters. The results of this study encourage patients to see urologists and physicians to introduce urologist to patients.

Abstract
Abstract
Study question
Does the area of oocyte perivitelline space have an effect on fertilization and embryo development following intracytoplasmic sperm injection?
Summary answer
The area of oocyte perivitelline space has not an effect on the fertilization but the embryo development following intracytoplasmic sperm injection.
What is known already
Oocyte perivitelline space has a lot of variation at intracytoplasmic sperm injection (ICSI). Some researchers reported that the characteristics of perivitelline space (large or small) affect embryo development, pregnancy, and implantation. However, these studies did not accurately calculate the area of perivitelline space. Therefore, little information is available on the effect of the area of oocyte perivitelline space on fertilization and embryo development following ICSI. The purpose of this study was to calculate and classify the area of oocyte perivitelline space and investigate the effect of the area of perivitelline space on fertilization and embryo development following ICSI.
Study design, size, duration
1. We retrospectively investigated 634 mature oocytes that were conducted ICSI between January 2021 and December 2021. The area of each oocyte perivitelline space was defined from between the area of circle calculated from the inner layer of zona pellucida and cytoplasm and divided into 3 groups (-9%, 10-19%, 20%-).
2. We retrospectively calculated the diameter of an inner layer of zona pellucida and cytoplasm and compared it with the 3 groups (-9%, 10-19%, 20%-).
Participants/materials, setting, methods
1. The fertilization, survival, good quality day-3 embryo, blastocyst, good quality blastocyst rates following ICSI were compared with the 3 groups (-9%, 10-19%, 20%-).
2. The average diameter of an inner layer of zona pellucida and cytoplasm of each oocyte for the 3 groups (-9%, 10-19%, 20%-) were compared.
The data were analyzed by Fisher’s exact test, residual analysis, one-way ANOVA test, with Bonferroni correction as appropriate to determine the statistical differences among groups.
Main results and the role of chance
1. The survival rates of perivitelline space -9%, 10-19%, 20%- groups were 100% (109/109), 96% (363/378), 94% (138/147), the fertilization rates were 89% (97/109), 88% (331/378), 86% (127/147), the good quality day-3 embryo rates were 56% (54/97), 70% (232/331), 70% (89/127) respectively. No significant difference was observed between these comparison items. The blastocyst rates of perivitelline space -9%, 10-19%, 20%- groups were 51% (47/92), 69% (222/321), 82% (93/114), the good quality blastocyst rates were 22% (20/92), 40% (129/321), 52% (59/114) respectively. The blastocyst and good quality blastocyst rates of perivitelline space -9% group showed significantly lower results. On the other hand, the blastocyst and good quality blastocyst rates of perivitelline space 20%- group showed significantly higher results.
2. The average diameter of an inner layer of zona pellucida of perivitelline space -9%, 10-19%, 20%- groups were 125 ± 4 µm, 129 ± 5 µm, 136 ± 6 µm, the average diameter of the cytoplasm of perivitelline space were 121 ± 4 µm, 119 ± 4 µm, 118 ± 4 µm respectively. Significant differences were observed in all pairs of groups of the average diameter of an inner layer of zona pellucida and cytoplasm.
Limitations, reasons for caution
The area of oocyte perivitelline space was calculated at only one plane.
Wider implications of the findings
Oocytes with narrow perivitelline space might have a wide region of adhesive between the cytoplasm surface and an inner layer of the zona pellucida which resulted in a smaller diameter of the zona pellucida and lower blastocyst rate by forming cytoplasmic fragments (Yumoto K et al. JARG. 2020 ;37(6):1349-1354.).

Abstract
Whole transcriptome profiling is a promising technique in adrenal studies; however, whole transcriptome profiling of adrenal disease using formalin-fixed paraffin-embedded (FFPE) samples has to be further explored. The aim of this study was to evaluate the utility of transcriptome data from FFPE samples of adrenocortical tumors. We performed whole transcriptome profiling of FFPE and fresh frozen samples of adrenocortical carcinoma (ACC, n = 3), aldosterone-producing adenoma (APA, n = 3), and cortisol-producing adenoma (CPA, n = 3), and examined the similarity between the transcriptome data. We further examined whether the transcriptome data of FFPE samples could be used to distinguish tumor types and detect marker genes. The number of read counts was smaller in FFPE samples than in fresh frozen samples (P < 0.01), while the number of genes detected was similar (P = 0.39). The gene expression profiles of FFPE and fresh frozen samples were highly correlated (r = 0.93, P < 0.01). Tumor types could be distinguished by consensus clustering and principal component analysis using transcriptome data from FFPE samples. In the differential expression analysis between ACC and APA-CPA, known marker genes of ACC (e.g., CCNB2, TOP2A, and MAD2L1) were detected in FFPE samples of ACC. In the differential expression analysis between APA and CPA, known marker genes of APA (e.g., CYP11B2, VSNL1, and KCNJ5) were detected in the APA of FFPE samples. The results suggest that FFPE samples may be a reliable alternative to fresh frozen samples for whole transcriptome profiling of adrenocortical tumors.

Abstract
The vascular endothelial growth factor (VEGF)/VEGF receptor 2 (VEGFR2) signaling pathway plays an important role in tumor angiogenesis. VEGFR2 is expressed not only in vascular endothelial
cells but also in tumor cells; however, the relationship of VEGF/VEGFR2 expression and tumor proliferation has yet to be elucidated. In addition, since several studies have reported that
VEGFR2 inhibitors are more effective against epithelial tumors than mesenchymal tumors, there may be a difference in VEGF/VEGFR2 expression between epithelial and mesenchymal tumors. The
purpose of this study was to elucidate differences in VEGF/VEGFR2 expression between epithelial and mesenchymal tumors and the relationship of VEGF/VEGFR2 expression and proliferation in
canine tumor cells. We assessed 29 epithelial and 21 mesenchymal canine tumors for microvessel density (MVD), mRNA transcription levels of von Willebrand Factor
(vWF) and endoglin, expression of VEGF, VEGFR2, and phosphorylated VEGFR2 (pVEGFR2), and proliferation index (PI) using real-time reverse transcription
polymerase chain reaction and immunohistochemistry. VEGFR2 expression on vascular endothelial cells, MVD, and mRNA transcription levels of vWF and endoglin
were not significantly different between the two groups. However, expression of VEGF, VEGFR2, and pVEGFR2 was higher in epithelial tumors (P<0.01). Moreover, PI
correlated with pVEGFR2 expression in only epithelial tumors (P<0.01, Rs=0.543). These results suggest that the activity of VEGF/VEGFR2 signaling in tumor cells is raised
in epithelial tumors, and that this signaling pathway may be related to tumor cell proliferation in epithelial tumors.

Abstract
Objectives Gout, caused by chronic elevation of serum uric acid levels, is the commonest form of inflammatory arthritis. The causative effect of common and rare variants of ATP-binding cassette transporter G2 (ABCG2/BCRP) on gout risk has been studied, but little attention has been paid to the effect of common (rs121907892, p.W258X) and rare variants of urate transporter 1 (URAT1/SLC22A12) on gout, despite dysfunctional variants of URAT1 having been identified as pathophysiological causes of renal hypouricaemia. Methods To address this important but overlooked issue, we investigated the effects of these URAT1 variants on gout susceptibility, using targeted exon sequencing on 480 clinically defined gout cases and 480 controls of Japanese males in combination with a series of functional analyses of newly identified URAT1 variants. Results Our results show that both common and rare dysfunctional variants of URAT1 markedly decrease the risk of gout (OR 0.0338, reciprocal OR 29.6, P = 7.66 × 10−8). Interestingly, we also found that the URAT1-related protective effect on gout eclipsed the ABCG2-related causative effect (OR 2.30–3.32). Our findings reveal only one dysfunctional variant of URAT1 to have a substantial anti-gout effect, even in the presence of causative variants of ABCG2, a ‘gout gene’. Conclusion Our findings provide a better understanding of gout/hyperuricaemia and its aetiology that is highly relevant to personalized health care. The substantial anti-gout effect of common and rare variants of URAT1 identified in the present study support the genetic concept of a ‘Common Disease, Multiple Common and Rare Variant’ model.

Abstract
A 50-year-old woman presented with coma and hemorrhagic shock. A rapid influenza antigen test revealed influenza A infection; other laboratory examinations ruled out any other suspected infections. She was diagnosed with hemorrhagic shock and encephalopathy syndrome (HSES) induced by influenza A. She was administered methylprednisolone pulse therapy and peramivir. Subsequently, she was discharged without any sequelae. Only a few cases of influenza-induced HSES have been reported, and the clinical outcomes were very poor. We herein report a successfully treated adult case of influenza-induced HSES and review this rare syndrome.

Abstract
Anti-angiogenic therapy is a cancer treatment strategy targeting new blood vessel formation. Microvessel density (MVD) is a histopathological method for evaluating angiogenesis and endoglin is used as an activated endothelial marker in human medicine. The assessment of the treatment effect using MVD is difficult because it is a non-repeatable method. To develop a repeatable method for evaluating angiogenesis, we investigated correlations among MVD, mRNA transcription levels of endothelial markers and angiogenesis factors, and confirmed the agreement of mRNA transcription levels between tissue samples and small samples obtained by fine needle aspiration (FNA). The various types of spontaneous tumours were collected from 51 dogs. MVD was assessed by immunostaining for von Willebrand factor (vWF). mRNA transcription levels of vWF, endoglin, vascular endothelial growth factor (VEGF) and VEGF receptor-2 (VEGFR2) were analysed using real-time reverse transcription polymerase chain reaction (real-time RT-PCR). There were significant correlations between MVD and mRNA transcription levels of vWF, endoglin and VEGFR2. VEGFR2 was more strongly correlated with endoglin (P <.01, Rs = 0.649) than vWF (P <.01, Rs = 0.512), indicating that angiogenesis can be evaluated more accurately by the measurement of mRNA transcription levels of endoglin. The mRNA transcription levels in tissue and FNA samples were strongly correlated, suggesting that evaluating angiogenesis using FNA samples is possible. In conclusion, we developed a repeatable and objective method for angiogenesis evaluation using mRNA transcription levels of endothelial markers by FNA sampling.

Abstract
Investigating slow earthquake activity in subduction zones provides insight into the slip behavior of megathrusts, which can provide important clues about the rupture extent of future great earthquakes. Using the S-net ocean-bottom seismograph network along the Japan Trench, we mapped a detailed distribution of tectonic tremors, which coincided with very-low-frequency earthquakes and a slow slip event. Compiling these and other related observations, including repeating earthquakes and earthquake swarms, we found that the slow earthquake distribution is complementary to the Tohoku-Oki earthquake rupture. We used our observations to divide the megathrust in the Japan Trench into three along-strike segments characterized by different slip behaviors. We found that the rupture of the Tohoku-Oki earthquake, which nucleated in the central segment, was terminated by the two adjacent segments.

Abstract
Disseminated nontuberculous mycobacterial (NTM) infections usually occur in severely immunosuppressed patients. These infections may also occur in previously immunocompetent patients with acquired anti-interferon-gamma antibodies (anti-IFN-γ Abs). A previously healthy 33-year-old man presented with a 3-week history of cough and fever. Chest computed tomography showed air-space consolidation in the middle lobe of the right lung and enlargement of the supraclavicular, mediastinal, and hilar lymph nodes. Tissue samples obtained via mediastinoscopy showed granuloma formation with acid-fast bacteria; cultures from the tissue revealed Mycobacterium kansasii. Accordingly, a diagnosis of disseminated M. kansasii disease was made. The positive control tested negative in the QuantiFERON-TB Gold In-tube test, suggesting the presence of anti-IFN-γ Abs. The ELISA test for anti-IFN-γ Abs demonstrated an increased titer. Antimycobacterial drug treatments were initiated after diagnosis. His symptoms improved over 2 months, and he remains well on outpatient management. Disseminated M. kansasii disease is a very rare condition suggestive of immunosuppression. Testing for anti-IFN-γ antibodies might be important in all cases of disseminated M. kansasii disease.

Abstract
Babesia rossi infection has been reported to be associated with the high prevalence of pancreatitis in dogs. In this study, we retrospectively investigated whether
pancreatitis occurs in B. gibsoni-infected dogs. The clinical manifestations, and hematological and serum biochemical examination results, including canine
pancreatic-specific lipase (cPL), in 20 B. gibsoni-infected dogs were analyzed. The cPL concentration exceeded 400 µg/l in only 2 dogs, and
they were suspected of having pancreatitis. Although the cPL concentration did not correlate with the degree of anemia or the level of parasitemia, it correlated with the band neutrophil
count, platelet count, and blood urea nitrogen (BUN) level. Our study suggested that the prevalence of pancreatitis is lower among B. gibsoni-infected dogs than B.
rossi-infected dogs.

Abstract
Feline polycystic kidney disease (PKD), an inherited autosomal dominant disease, has been reported to occur mostly in Persian or Persian related cats, and to be associated with a mutation
from C to A at position 10063 in exon 29 of the feline PKD1 gene (PKD1 mutation). Many clinical cases have been recognized in Japan, but the mutation rate
in cats has not been reported. The objective of this study was to determine epidemiological characteristics and clinical features in cats with the PKD1 mutation. Referring
veterinarians sent blood samples of 377 cats for the PKD1 gene evaluation. The blood samples were from 159 cats with renal cysts confirmed by ultrasonography, 60 cats
without renal cysts, and 158 cats that did not undergo ultrasonography. In total, 150 cats carried the PKD1 mutation and the signalment, site and number of renal cysts, and
results of blood test were evaluated in cats with the PKD1 mutation. The breeds with the highest rate of the PKD1 mutation were Persian (46%), Scottish Fold
(54%) and American Shorthair cats (47%). However, mixed breed cats also showed high rates of the PKD1 mutation. Of cats with the mutation, the incidence of high plasma
creatinine (≥1.6 mg/dl) was greater in cats ≥3 years old, although a few cats ≥9 years of age had low plasma creatinine (<1.6 mg/dl). The coincidence of
renal and hepatic cysts was 12.6%, with the high prevalence in Persian cats (31%).

Abstract
Thymic carcinomas is rare and highly aggressive carcinoma. Most patients with them are diagnosed as being at surgically unresectable stages due to it. There are several reports which showed the effect of chemotherapy, however, it is controversial. Recently, immune checkpoint inhibitors have changed conventional chemotherapy due to their effect against various types of cancers. We administered nivolumab, anti-Programmed Cell Death (PD)-1 antibody, to four patients with unresectable thymic carcinomas who had previously undergone conventional chemotherapy. A histopathology on tumors from these patients revealed the presence of squamous cell carcinoma and PD-L1 high expression. After treatment with nivolumab, it seemed to be beneficial to all patients; The best clinical responses of 3 patients were partial response and that of the other one was stable disease. None of them experienced severe immune-related adverse events. Our results suggest the potential benefits of using these inhibitors to treat thymic carcinomas in real world clinical setting as is the cases in recent clinical trials for the evaluation of immune checkpoint inhibitors for the treatment of thymic carcinoma.

Abstract
In the treatment of immunotherapy with immune checkpoint inhibitors, we often experience immune-related adverse event which manifest most frequently as a skin disorder, and very rarely as a renal disorder. In our manuscript, we report the case of a 71-year-old man with nivolumab-induced severe acute kidney injury (AKI) in which the time from treatment initiation to the onset of AKI was the longest among the previously reported cases (377 days). Prolonged follow-up is therefore warranted to detect late-onset AKI.

Abstract
The existence of a lung cavity on chest radiographs suggests the presence of lung disease, including benign or malignant disease. Lung cancer, tuberculosis, and fungal infection are all known for developing lung cavity. In addition, there are some characteristic findings in the differential diagnosis of cavitary disease, although these cavitary diseases often coexist. Here, we report two cases that presented cavitary lung cancer with concomitant chronic infectious disease. One patient showed pulmonary aspergillosis and lung adenocarcinoma, the other patient showed Mycobacterium avium complex lung disease and lung adenocarcinoma. These chronic infectious diseases develop slowly, and clinicians often follow up over several months. To reduce the delay in diagnosis of malignancy, clinicians should aggressively collect the specimens from cavitary lesions and make a correct diagnosis when encountering lung cavity in diagnostic clinical imaging.

Abstract
Complete pressure unloading of the ventricles can preserve ischemically damaged myocardium. Most clinical left heart assist device (LVAD) systems used after ischemic injury of the heart apply atrial cannulation which does not ensure pressure unloading. In order to assess the effect of the implantation of an intracorporeal LVAD on the function of the natural heart, we determined the ejection fraction (EF) in four male Holstein calves (90–105 kg) before and after insertion of a Cleveland Clinic pneumatic LVAD. A gated blood pool scan was obtained with a gamma camera after injection of 40 mCi Tc-labelled albumin. The animals were restrained in a sling to avoid movement artifacts. All animals showed a drop of 65 ± 12% to 42 ± 14% EF in the first postoperative (p.o.) week. Left ventricular output did not maintain sufficient blood pressure as assessed by pump-off tests. Systolic blood pressure dropped from 122 ±6.5 mm Hg to 81 ± 6 mm Hg without pump support on the morning of the first p.o. day. Apical coring and possible restrained heart movement by the implanted LVAD may lead to impaired myocardial function that renders the individual LVAD dependent until adaptative corrections take place.

Abstract
In order to analyze the hemodynamic parameters in prosthetic circulation as an entity and not as decomposed parts, non linear mathematical analyzing techniques, including the fractal dimension analyzing theory, were utilized. Two pneumatically actuated ventricular assist devices were implanted, as biventricular bypasses (BVB), in chronic animal experiments, using four healthy adult goats. For the comparison between the natural and prosthetic circulation in the same animals, the BVB type complete prosthetic circulation model with ventricular fibrillation, was adopted. All hemodynamic parameters with natural and prosthetic circulation were recorded under awake conditions, and calculated with a personal computer system. Using the non-linear mathematical technique, the arterial blood pressure waveform was embedded into the return map as the beat-to-beat time series data and fractal dimension analysis were performed to analyze the reconstructed attractor. By the use of the Box counting method, fractal dimension analysis of the hemodynamics was performed. Return map of the hemodynamics during natural and artificial circulation showed fractal characteristics, and fractal dimension analysis of the arterial blood pressure revealed the fact that lower dimensional fractal dynamics were evident during prosthetic circulation. Fractal time series data is suggested to have robustness and error resistance, thus our results suggest that the circulatory regulatory system with an artificial heart may have these desired characteristics.

Abstract
A 65‐year‐old man with chronic progressive pulmonary aspergillosis (CPPA) was admitted for the treatment of lung adenocarcinoma while receiving an immune checkpoint inhibitor, nivolumab. The tumour responded well to the therapy, but the cavity of CPPA became large in contrast to the tumour after 20 courses of therapy. He was diagnosed as having exacerbation of CPPA and successfully and concurrently treated with an antifungal agent and nivolumab. Since there was absence of obvious immunosuppression and the presence of a drastic effect on tumour remission during nivolumab therapy, this phenomenon suggested that the trigger of CPPA progression was dependent not on immunosuppression but on a hyperreaction to microorganisms, which was similar to the immune reconstitution inflammatory syndrome caused by nivolumab. This was a thought‐provoking case in which the immune checkpoint inhibitor had a paradoxical effect for the tumour and infection.

Abstract
The mechanism of the development of diminazene aceturate (DA) resistance in Babesia gibsoni is still unknown even though DA-resistant B. gibsoni isolate was previously developed in vitro. To clarify the mechanisms of DA-resistance in B. gibsoni, we initially examined the intracellular DA content in the DA-resistant isolate using high-performance liquid chromatography, and compared it with that in the wild-type. As a result, the intracellular DA content in the DA-resistant isolate was significantly lower than that in the wild-type, suggesting that the decreased DA content may contribute to DA-resistance. Additionally, the glucose consumption of the DA-resistant isolate was significantly higher than that of the wild-type, indicating that a large amount of glucose is utilized to maintain DA-resistance. It is possible that a large amount of energy is utilized to maintain the mechanisms of DA-resistance. It was reported that as the structure of DA is similar with that of adenosine, DA may be taken up by the P2 transporter, which contributes to the uptake of adenosine, in Trypanosoma brucei brucei, and that the uptake of adenosine is decreased in DA-resistant T. brucei brucei. In the present study, the adenosine incorporation in the DA-resistant B. gibsoni isolate was higher than in the wild-type. Moreover, the adenosine incorporation in the wild-type was not inhibited by the presence of DA. These results suggest that adenosine transport in B. gibsoni is not affected by DA and may not mediate DA-resistance. To clarify the mechanism of the development of DA resistance in B. gibsoni, we should investigate the cause of the decreased DA content in the DA-resistant isolate in the future.

Abstract
HLA 1-locus-mismatched unrelated donors (1MMUD) have been used in allogeneic hematopoietic stem cell transplantation (allo-HCT) for patients who lack an HLA-matched donor. We retrospectively analyzed 3313 patients with acute leukemia or myelodysplastic syndrome who underwent bone marrow transplantation from an HLA allele-matched unrelated donor (MUD) or 1MMUD between 2009 and 2014. We compared the outcomes of MUD (n=2089) and 1MMUD with antithymocyte globulin (ATG) (1MM-ATG(+); n=109) with those of 1MMUD without ATG (1MM-ATG(-); n=1115). The median total dose of ATG (thymoglobulin) was 2.5 mg/kg (range 1.0-11.0 mg/kg) in the 1MM-ATG(+) group. The rates of grade III-IV acute GvHD, non-relapse mortality (NRM) and overall mortality were significantly lower in the MUD group than in the 1MM-ATG(-) group (hazard ratio (HR) 0.77, P=0.016; HR 0.74; P<0.001; and HR 0.87, P=0.020, respectively). Likewise, the rates of grade III-IV acute GVHD, NRM and overall mortality were significantly lower in the 1MM-ATG(+) group than in the 1MM-ATG(-) group (HR 0.42, P=0.035; HR 0.35, P<0.001; and HR 0.71, P=0.042, respectively). The outcome of allo-HCT from 1MM-ATG(-) was inferior to that of allo-HCT from MUD even in the recent cohort. However, the negative impact of 1MMUD disappeared with the use of low-dose ATG without increasing the risk of relapse.

Abstract
A nationwide retrospective study for the clinical outcomes of 99 patients who had received thymoglobulin at a median total dose of 2.5 mg/kg (range, 0.5-18.5 mg/kg) as a second-line treatment for steroid-resistant acute GvHD was conducted. Of the 92 evaluable patients, improvement (complete or partial response) was observed in 55 patients (60%). Multivariate analysis demonstrated that male sex and grade III and IV acute GvHD were associated with a lower improvement rate, whereas thymoglobulin dose (<2.0, 2.0-3.9 and ⩾4.0 mg/kg) was NS. Factors associated with significantly higher nonrelapse mortality included higher patient age (⩾50 years), grade IV acute GvHD, no improvement of GvHD and higher dose of thymoglobulin (hazard ratio, 2.55; 95% confidence interval, 1.34-4.85; P=0.004 for 2.0-3.9 mg/kg group and 1.79; 0.91-3.55; P=0.093 for ⩾4.0 mg/kg group). Higher dose of thymoglobulin was associated with a higher incidence of bacterial infections, CMV antigenemia and any additional infection. Taken together, low-dose thymoglobulin at a median total dose of 2.5 mg/kg provides a comparable response rate to standard-dose thymoglobulin reported previously, and <2.0 mg/kg thymoglobulin is recommended in terms of the balance between efficacy and adverse effects.

Abstract
Propofol (2,6-diisopropylphenol), being used as an intravenous sedative and anesthetic
agent, influences not only upon nervous system but also for host inflammatory response
through modulating neutrophil functions. This study is designed to evaluate the modulating
effects of propofol and its lipid carrier administration at clinically relevant rate on
canine neutrophil functions. Clinically healthy beagle dogs were received propofol (8.8
mg/kg) from cephalic vein and maintained with propofol dropping infusion (26.4 mg/kg/hr).
Blood samples were collected from the dogs before infusion and 30 min after the start of
propofol administration, and neutrophil functions were evaluated. The dogs were also
administered lipid carrier, and neutrophil functions were evaluated in the same manner as
propofol administration. Peripheral white blood cell and neutrophil counts decreased after
the propofol or lipid carrier administration. The administration of propofol or lipid
carrier significantly reduced neutrophil adherence ability. The superoxide production of
neutrophils was measured by luminol-dependent chemiluminescence response using with
opsonized zymosan. Peak height of neutrophil chemiluminescence curve was reduced by
propofol and lipid carrier administration, on the contrary, peak time of neutrophil
chemiluminescence curve was delayed. Administration of propofol or lipid carrier also
reduced neutrophil adherence ability to nylon fibers. In the present study, we showed the
modulating effects of propofol and its lipid carrier on canine neutrophil functions.
However, there was no significant difference in the modulating effects between propofol
group and lipid carrier group. Therefore, the modulating effects observed here were deeply
concerned in lipid carrier administration.

Abstract
BACKGROUND The efficacy of tapentadol extended release (ER) for managing chronic pain has been demonstrated in large-scale, randomized, controlled, phase 3 studies (N=318-1,030) in patients with chronic osteoarthritis (OA) pain, low back pain (LBP), and pain related to diabetic peripheral neuropathy (DPN), which led to registration in many regions, including the United States and Europe. 2 pilot 12-week, randomized, double-blind, placebo-controlled phase 2 studies of tapentadol ER for chronic pain (OA knee pain or LBP, n=91; DPN or peripheral herpetic neuralgia [PHN] pain; n=91) were conducted in Japan. These small exploratory studies were substantially underpowered compared with the registration trials. METHODS Patients in both studies were randomized (2:1) to tapentadol ER (25-250 mg) or placebo for 12 weeks (≤6-week titration plus maintenance periods). RESULTS For the primary efficacy endpoint (change in pain intensity from baseline to last week of treatment; last observation carried forward), both studies failed to differentiate between tapentadol ER and placebo; least-squares mean differences (95% confidence intervals) for tapentadol ER vs. placebo were -0.1 (-1.04, 0.80) in the OA/LBP study and -0.1 (-1.10, 0.99) in the DPN/PHN study. More than 80% of patients took concomitant analgesics during these studies. Tapentadol was well tolerated. CONCLUSIONS Both studies were associated with methodological issues, including populations with different disease entities, small sample sizes, use of concomitant analgesics, and possible placebo effect that may have led to the failure to differentiate between tapentadol ER and placebo.

Abstract
The Babesia gibsoni heat shock protein 90 (BgHSP90)
gene was cloned and sequenced. The length of the gene was 2,610 bp with two introns. This
gene was amplified from cDNA corresponding to full length coding sequence (CDS) with an
open reading frame of 2,148 bp. A phylogenetic analysis of the CDS of
HSP90 gene showed that B. gibsoni was most closely
related to B. bovis and Babesia sp. BQ1/Lintan and lies
within a phylogenetic cluster of protozoa. Moreover, mRNA transcription profile for
BgHSP90 exposed to high temperature were examined by quantitative
real-time reverse transcription-polymerase chain reaction. BgHSP90 levels
were elevated when the parasites were incubated at 43°C for 1 hr.

A new structural design is proposed for wrinkling to improve mechanical durability by exploiting a porous polymer film embedded on the surface of an elastomer, which acts as a hard layer, buckles into wrinkles and effectively suppresses fatal failures such as delamination and cracking.

Abstract
Brominated flame retardants (BFRs) have been detected in indoor dust in many studies, at concentrations spanning several orders of magnitude. Limited information is available on the pathways via which BFRs migrate from treated products into dust, yet the different mechanisms hypothesized to date may provide an explanation for the range of reported concentrations. In particular, transfer of BFRs to dust via abrasion of particles or fibers from treated products may explain elevated concentrations (up to 210 mg g(-1)) of low volatility BFRs like decabromodiphenyl ether (BDE-209). In this study, an indoor dust sample containing a low concentration of hexabromocyclododecane, or HBCD, (110 ng g(-1) ΣHBCDs) was placed on the floor of an in-house test chamber. A fabric curtain treated with HBCDs was placed on a mesh shelf 3 cm above the chamber floor and abrasion induced using a stirrer bar. This induced abrasion generated fibers of the curtain, which contaminated the dust, and ΣHBCD concentrations in the dust increased to between 4020 and 52 500 ng g(-1) for four different abrasion experiment times. The highly contaminated dust (ΣHBCD at 52 500 ng g(-1)) together with three archived dust samples from various UK microenvironments, were investigated with forensic microscopy techniques. These techniques included Micro X-ray fluorescent spectroscopy, scanning emission microscopy coupled with an energy dispersive X-ray spectrometer, Fourier transform infrared spectroscopy with further BFR analysis on LC-MS/MS. Using these techniques, fibers or particles abraded from a product treated with BFRs were identified in all dust samples, thereby accounting for the elevated concentrations detected in the original dust (3500 to 88 800 ng g(-1) ΣHBCD and 24 000 to 1,438 000 ng g(-1) for BDE-209). This study shows how test chamber experiments alongside forensic microscopy techniques, can provide valuable insights into the pathways via which BFRs contaminate indoor dust.

Abstract
BACKGROUND Clostridium difficile is a major cause of nosocomial diarrhea. The incidence and prognosis of C. difficile-associated diarrhea (CDAD) has not yet been assessed in adult patients after unrelated cord blood transplantation (uCBT). METHODS The medical records of 135 adult unrelated cord blood transplant recipients were reviewed retrospectively to investigate the clinical features of CDAD after uCBT. These data were compared to medical records of 39 unrelated bone marrow transplant recipients and 27 related peripheral blood stem cell transplant recipients as controls. RESULTS A total of 17 recipients developed CDAD, with onset occurring at a median of 22 days (range, 0-56 days) after transplantation. Among the unrelated cord blood transplant recipients, 11 (9%) developed CDAD. These results were comparable with those of CDAD after unrelated bone marrow transplantation (uBMT) (2/39, 6%) and related peripheral blood stem cell transplantation (rPBSCT) (4/27, 16%) (P=0.37). Fifteen of the infected recipients were successfully treated with oral metronidazole, vancomycin, or cessation of antibiotics. The remaining 2 recipients who developed CDAD after uCBT died of other causes. The development of CDAD did not negatively affect overall survival after uCBT. CONCLUSIONS These data indicate that the incidence and prognosis of CDAD after uCBT are comparable with those after uBMT and rPBSCT.

Abstract
It has been reported that losartan, an angiotensin II receptor blocker, alters the circadian rhythm of melatonin secretion and significantly reduces melatonin production. However, this finding has been confirmed at the animal experiment level only, and there are no reports of studies in humans. Therefore, we performed this study to confirm the reproducibility of the aforementioned findings of animal experiments in humans. Ten male subjects who were in good general health and free from any medical condition were recruited for this study. After a preliminary observation period of 7 days, the subjects received oral losartan treatment, 50 mg daily for 7 days. Blood samplings for measurement of the plasma melatonin concentrations were performed on day 7 of the preliminary observation period and day 7 of the losartan treatment period. The circadian rhythm of melatonin secretion after the 7-day treatment with losartan showed no significant difference from that recorded before the losartan administration. The significant decrease of the home blood pressure was observed on the afternoons. The blood samples showed significant decrease of the serum sodium and uric acid levels, along with a significant increase of the serum potassium level. The pharmacological actions of losartan at the ordinarily used clinical dose level were confirmed in humans, however, no significant inhibitory effect of the drug on melatonin secretion could be confirmed. These results are expected to be useful for guiding the proper use of angiotensin II receptor blockers.

Abstract
A six-year-old, neutered, female golden retriever was presented with generalised, dark purple to black cutaneous nodules and gastrointestinal haemorrhage. Histopathologically, all cutaneous nodules were diagnosed as benign cavernous haemangiomas. Endoscopic analysis revealed similar nodules in the oesophagus, stomach and duodenum. At laparotomy, similar nodules were seen on the visceral peritoneal lining of abdominal organs. Metastatic haemangiosarcoma was ruled out based on histological features and lack of primary tumour in spleen, liver or heart ultrasonographically. Blood loss associated with gastrointestinal haemorrhage was managed with blood transfusion. To the authors' knowledge, this is the first canine case of multi-system progressive angiomatosis resembling blue rubber bleb nevus syndrome in humans.
