Abstract
Although glomerular damage caused by diabetic nephropathy was thought to be irre-versible, in recent years, there have been reports on improvement in glomerular damage with strict glycemic control. However, few reports are available on the pathologic course after renal transplantation of donor-derived grafts with findings of diabetic nephropathy. A 53-year-old woman underwent an ABO blood-type compatible living-donor renal transplant. The recipient had no history of diabetes, and fasting blood glucose and hemo-globin A1c (HbA1c) levels were both normal. The donor was a 57-year-old male who had received treatment for type 2 diabetes mellitus for 10 years. Transplant renal biopsy performed 1 h after revascularization showed mesangial matrix expansion and arterial hyalinosis due to diabetic nephropathy. The blood glucose level was within the normal range after transplantation. Mesangial matrix expansion and arterial hyalinosis disap-peared in allograft biopsy samples 7 years after transplantation. We observed significant improvement in the pathological findings of donor-derived diabetic nephropathy after renal transplantation in the subsequent follow-ups.

Abstract
A 52-year-old male had pain in the right back and right hypochondrium, and an abdominal CT scan revealed a 49-mm tumor in the right upper perirenal space. Additional MRI and PET-CT suggested that the tumor may be a primary adrenal carcinoma and could invade the liver and diaphragmatic leg. The tumor was completely removed by laparotomy and histopathologically diagnosed as retroperitoneal primary undifferentiated pleomorphic sarcoma. The patient has remained recurrence-free for 1.5 years after the surgery.

Abstract
We present a case of a 68-year-old male patient who underwent ABO-incompatible living kidney transplantation from his wife because of immunoglobulin A nephropathy 13 years ago. Over time, the patient showed a gradual decline in graft function and required reinitiation of hemodialysis because of fluid overload, which led to his admission to our hospital. An arteriovenous fistula was created, and subsequently, hemodialysis therapy was started. Because he had chronic cytomegalovirus retinopathy and thrombotic microangiopathy due to immunosuppressive therapy at admission, mycophenolate mofetil and tacrolimus were discontinued during hemodialysis initiation. Only low-dose prednisolone was continued. One week later, the patient had a fever, and chest computed tomography revealed bilateral pneumonia, which was not improved by antibiotics. The patient was diagnosed with organized pneumonia. After ruling out opportunistic infection, including pneumocystis pneumonia, increased doses of prednisolone resulted in the remission of organizing pneumonia.

Abstract
Introduction Since the approval of immune checkpoint inhibitors for renal cell carcinoma treatment, therapeutic efficacy has been enhanced. However, although autoimmune-related side effects may occur, rheumatoid immune-related adverse events seldom develop. Case presentation A 78-year-old Japanese man with renal cell carcinoma developed pancreatic and liver metastases after bilateral partial nephrectomy and was treated with ipilimumab and nivolumab. After 22 months, he developed arthralgia in limbs and knee joints, accompanied by limb swelling. The diagnosis was seronegative rheumatoid arthritis. Nivolumab was discontinued, and prednisolone was initiated, quickly improving symptoms. Although nivolumab was resumed after 2 months, arthritis did not recur. Conclusion Immune checkpoint inhibitors may cause a wide variety of immune-related adverse events. When arthritis is encountered during immune checkpoint inhibitor administration, seronegative rheumatoid arthritis should be differentiated from other types of arthritis, despite being less frequent.

Abstract
Ischemia-reperfusion injury (IRI) causes massive tissue damage. Renal IRI is the most common type of acute renal injury, and the defects caused by it may progress to chronic kidney disease (CKD). Rodent models of renal IRI, with various patterns, have been used to study the treatment of human kidney injury. A rat model of bilateral IRI, in which the bilateral kidney blood vessels are clamped for 60 min, is widely used, inducing both acute and chronic kidney disease. However, the molecular mechanisms underlying the effects of bilateral IRI on kidney cells have not yet been fully elucidated. This study aimed to perform a whole-transcriptome analysis of the IRI kidney using single-cell RNA sequencing. We found renal parenchymal cells, including those from the proximal tubule, the loop of Henle, and distal tubules, to be damaged by IRI. In addition, we observed significant changes in macrophage population. Our study delineated the detailed cellular and molecular changes that occur in the rat model of bilateral IRI. Collectively, our data and analyses provided a foundation for understanding IRI-related kidney diseases in rat models.

Abstract
Introduction The coronavirus disease 2019 pandemic emerged in December 2019. Renal transplant recipients receiving chronic immunosuppression are considered to be at a high risk of infection. Aside from upper respiratory tract symptoms, coronavirus disease 2019 has also been reported to cause acute kidney injury in 20-50% of infected cases. Case presentation A 62-year-old male renal transplant recipient presented with high fever, diarrhea, and cough, concurrent with rapid deterioration of graft function. The patient tested positive for coronavirus disease 2019. The pathological findings of the graft biopsy revealed diffuse flattening of tubular epithelial cells and extensive loss of the brush border in proximal tubular cells. Mycophenolate mofetil was discontinued and sotrovimab, remdesivir, intravenous immunoglobulin, and intravenous methylprednisolone were administered, resulting in gradual improvements in clinical symptoms and renal function. Conclusion We describe a case of a coronavirus disease 2019-infected kidney transplant recipient who developed severe acute kidney injury caused by severe acute tubular necrosis.

Abstract
OBJECTIVES Post-transplant lymphoproliferative disorder is a potentially life-threatening complication that has a greater risk of occurrence in the setting of immunosuppression and oncogenic viral infections after transplant surgery. Few studies have reported the cumulative incidence, histological subtypes and clinical outcomes of this disorder in kidney transplant recipients. METHODS We retrospectively investigated 34 post-transplant lymphoproliferative disorder patients diagnosed out of the 1210 kidney transplant recipients who had undergone the surgery at the two largest centers in Japan between January 1983 and December 2017. RESULTS A total of 32 patients (94.1%) developed late-onset post-transplant lymphoproliferative disorder (diagnosed 1 year after transplantation). The cumulative incidence rates were 0.76% and 1.59% at 5 and 10 years post-transplantation, respectively. The central nervous system was the most common site (35.3%, 12/34). Overall survival was similar between patients with and without central nervous system lesions (P = 0.676). Of all of the cases, 23.5% (8/34) were detected through cancer screening. Importantly, patients with screening-detected post-transplant lymphoproliferative disorder had better overall survival than those with the disorder who had been symptom detected (P = 0.0215). Overall survival was significantly reduced in patients who developed the disorder compared with those who did not (P = 0.0001). CONCLUSIONS Post-transplant lymphoproliferative disorder was more likely to occur in the late post-transplantation period, which showed that long-term medical examination for transplant recipients is required. Based on our findings, we propose vigilant, long-term, cancer screening in kidney transplant recipients.

Abstract
A 72-year-old male underwent an abdominal CT scan, which revealed a 17-mm nodular incidentaloma in fat tissue in the left perirenal space. Retroperitoneoscopic surgery was performed to remove the tumor and histopathological results revealed a PSA-positive adenocarcinoma, which was diagnosed as a metastatic lesion associated with prostate cancer. PSA was high at 30.083 ng/ml and MRI findings showed extracapsular extension of prostate cancer in the left peripheral zone of the prostate gland. Biopsy results with a Gleason score of 4 + 4 confirmed the diagnosis of prostate cancer. The case was diagnosed as prostate cancer metastasis in perirenal fat tissue.

Abstract
Kidney transplantation is the most promising treatment to improve mortality and life quality in end‐stage kidney disease; however, cancer remains a leading cause of death. Several factors including immunosuppressants might be associated with a gradual increase in cumulative cancer incidence after kidney transplantation. Risk factors for cancer and overall and cancer‐specific survival were analyzed in 1973 kidney transplant recipients from three study institutions in Japan. The 5‐, 10‐, 20‐, and 30‐year overall and cancer‐specific survival rates were 93.3%, 88.4%, 78.0%, and 63.6% and 99.4%, 98.0%, 95.3%, and 91.7%, respectively. The overall survival rate was significantly higher and the graft survival rate was significantly lower in recipients without cancer than in those with cancer. Older recipient age, longer dialysis duration before kidney transplantation, and history of transfusion were significant predictors of cancer. Dialysis duration before kidney transplantation was a prognostic factor of overall survival rate. Regarding cancer‐specific survival rates, older recipient age and dialysis duration before kidney transplantation were prognostic factors of worse cancer‐specific survival rates. The type of immunosuppressant was not associated with an increased cancer rate. Aggressiveness of immunosuppressant regimens or potent immunosuppressants might improve graft survival rate while inducing de novo cancer after kidney transplantation. Older age and longer dialysis duration before kidney transplantation were risk factors of cancer‐specific survival rate.

Abstract
We report a rare case of prostate cancer that apparently metastasized to the bladder and formed a pedunculated mass that caused a ball valve-like obstruction in urination. A 57-year-old man with metastatic prostate cancer was referred to the emergency department for acute urinary retention. Cystoscopy and magnetic resonance imaging revealed a pedunculated mass measuring approximately 2 cm in size in the bladder neck that appeared to cause urinary obstruction in a ball valve-like manner. Transurethral resection of the bladder tumor was performed that resolved his symptom, and histopathological findings confirmed a diagnosis of poorly differentiated prostate adenocarcinoma.

Abstract
Background:The development of rapid and accurate methods of diagnosing giant cell arteritis (GCA) is critical to prevent blindness and stroke, which may develop rapidly in patients with GCA. In 2018, EULAR published recommendations that the first imaging modality for GCA should be vascular ultrasonography without biopsy. However, many institutions still consider biopsy to make an important contribution to the diagnosis of GCA.Objectives:Our purpose is to eliminate blindness and stroke among GCA patients by optimizing diagnostic imaging and method to diagnose GCA employed by vascular ultrasonography (V-US), CT Angiography (CTA), MRI/A, and PET/CT without biopsy.Methods:We evaluated the clinical and serological characteristics of 20 patients who were diagnosed with GCA at our hospital from 2012 to 2018, and compared the image and biopsy findings of these patients. We then evaluated the effect of optimizing diagnostic imaging and methods for patients with suspected GCA who visited our hospital during 2019. Vascular mapping was carried out using V-US for 3DCTA and other imaging methods as references.Results:Table 1 shows the clinical characteristics of the study population. The sensitivity of CTA for GCA was 85.7% (12 of 14 patients), which was the highest of the studied imaging methods. All biopsy-positive cases were diagnosed as GCA, and we compared these cases with cases with positive imaging findings. This revealed that CTA findings were correct (i.e., positive) in 66.7% (four of six patients), MRI/A findings were correct in in 33.3% (three of nine), V-US findings were correct in 50.0% (three of six). Therefore, CTA exhibited the highest sensitivity for positive findings. Comparison of biopsy-positive cases with cases in which imaging findings were negative revealed that CTA findings were correct (negative) in 33.3% (two of six patients), MRI/A findings were correct in 55.6% (five of nine), V-US was correct in 50.0% (three of six). Thus, CTA had the lowest sensitivity for negative findings. Comparison of CTA findings of positive cases with other imaging modalities which reported positive findings revealed MRI/A findings to be correct in 44.4% (four of nine patients), PET/CT findings to be correct in 50.0% (one of two), V-US to be correct in 63.3% (five of eight). Thus, V-US had the highest agreement with CTA. We carried out vascular mapping by V-US using 3DCTA and other imaging methods and produced references to improve the accuracy of diagnosis. Using these references, we diagnosed five cases of GCA among the 20 patients; the positive predictive value of V-US was 80% (four of five patients) and negative predictive value was 86.7% (13 of 15 patients).Table 1.Baseline characteristics of the study sample The number of biopsies performed decreased from 50% (10 of 20 patients) from 2012 to 2018 to 15% (3 of 20 patients) in 2019. Two cases in the present study had positive findings in both biopsy and V-US; in one case, biopsy, CTA, and MRI/A were negative while V-US revealed positive findings. No patients with GCA developed blindness or stroke during 2019.Conclusion:We propose that V-US should be performed as the first examination for the diagnosis of GCA by the creation of vascular mappings when GCA is suspected in order to prevent blindness and stroke.References:[1]Christian Dejaco et al.EULAR recommendations for the use of imaging in large vasculitis in clinical practice.Annals of the Rheumatic Diseases,2018 May;77(5):636-643[2]Kawamoto T et al.Diagnosis of giant cell arthritis by head-contrast three-dimensional computed tomography angiography.Journal of Medical Case Reports2019 Sep 11;13(1):285.Figure 1.Left side is before, right side is after thrapy.

Abstract
Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown etiology that affects mostly young women. Multiorgan complications and prolonged treatment significantly cause physical and mental stress in patients. Improving patients’ quality of life (QOL) in SLE treatment is essential. We examined the treatment effects on disease activity and QOL of SLE patients.Objectives:In recent years, lupus low disease activity state (LLDAS) has been proposed as a treatment target for SLE. Patients who achieve LLDAS have a low recurrence rate for lupus and a low risk of serious complications (1). The aim of this study is to investigate whether achieving LLDAS reduces not only recurrence rate and complications of SLE but also improves patients’ QOL.Methods:A total of 104 SLE patients were enrolled in our prospective SLE registry study (Juntendo, Multi-center, Prospective cohort for investigation of clinical course and outcome in SLE: JUMP) conducted at our institution. SLE was diagnosed using the American College of Rheumatology (ACR) 1982 criteria (revised in 1997). QOL was evaluated using the standard version of the 36-item short form health survey version 2 (SF36v2). Participants were divided into the LLDAS achievement and non-achievement groups, and the characteristics of each group including results of SF36v2 were examined.Results:This study included 104 SLE patients, 94 female and 10 male, and the average age and disease duration were 46.4±13.8 and 14.5±11.3 years, respectively. The average corticosteroid dose was 8.0±17.4 mg/day in terms of prednisolone, and anti-dsDNA antibody titer was 16.8±38.5 IU/ml. Of the 104 patients, 57 achieved LLDAS. The subscale’s standard scoring using SF36v2 for role physical (RP) was 78.9±24.0 and 64.6±27.6 (P<0.01), general health (GH) was 50.0±17.0 and 42.0±19.3 (P<0.05), vitality (VT) was 55.8±15.8 and 38.0±24.1 (P<0.01), social functioning (SF) was 82.0±20.7 and 66.5±26.3 (P<0.01), role emotional (RE) was 89.0±16.1 and 73.4±28.1 (P<0.01), and mental health (MH) was 72.4±15.9 and 58.3±21.8 (P<0.01) in the LLDAS achievement and non-achievement groups, respectively. Furthermore, scoring based on the national standard value in the LLDAS achievement group showed that two categories were >50. However, in the LLDAS non-achievement group, all categories were <50. In particular, RP, GH, VT, SF, RE, and MH of the LLDAS achievement group had significantly higher scores than the LLDAS non-achievement group (RP and GH: p<0.05 and VT, SF, RE and MH: p<0.01).Conclusion:Results of examining the association between LLDAS and QOL using SF36v2 in SLE patients showed that patients who achieved LLDAS had significantly better standard statistical scores in many subscale categories. Thus, LLDAS achievement as a treatment target for SLE patients greatly contributes to improving patients’ QOL.References:[1]Franklyn K, et al.

Abstract
Angiosarcoma arising in the retroperitoneal space is rare. We report a case of perirenal angiosarcoma presenting preoperative diagnostic difficulties. A 49-year-old man was referred to our department with left kidney mass. Specimens of CT-guided percutaneous needle biopsy of the mass did not contain any atypical cells suggestive of malignancy. A CT scan 6 months after embolization of the tumor revealed growth of the mass and two space-occupying lesions appearing in the liver. Laparoscopic resection of the left kidney with perirenal mass and one of the liver lesions was performed. Histopathological findings confirmed a diagnosis of perirenal angiosarcoma with hepatic metastases.

Abstract
The developmental competence of oocytes after cryopreservation is compromised by the physical injury due to the ice crystallisation. Recent studies have reported that polysaccharide (xylomannan) derived from the mycelium and fruit body of the basidiomycete Flammulina velutipes inhibits the ice recrystallisation in the cryopreserved Chinese hamster ovary cells. In this study, we aimed to clarify the effect of xylomannan from Flammulina velutipes on the developmental competence of bovine vitrified oocytes. Bovine ovaries were obtained from a local abattoir, and cumulus-oocyte complexes (COCs) were aspirated from follicles (2-6mm in diameter) using a 19-gauge needle attached to a syringe. The COCs were matured for 22h in tissue culture medium-199 supplemented with 5% fetal bovine serum (FBS), 0.02IUmL−1 FSH, and 10μgmL−1 gentamycin. After maturation, COCs were incubated in base solution (BS: 10% FBS-tissue culture medium-199, control group; n=149) or BS supplemented with 100μgmL−1 xylomannan (xylomannan group; n=175) for 1h before vitrification. All vitrification procedures were performed at room temperature. The COCs were equilibrated in BS with 3% ethylene glycol for 12min and then in vitrification solution (BS with 30% ethylene glycol, 1.0M sucrose) for 1min. The COCs were loaded on a Cryotop (Kitazato) and transferred into liquid nitrogen. The warming procedure was performed on a warm plate (42°C). The COCs were placed into BS supplemented with 0.5, 0.25, 0.125, and 0M sucrose for 5min each. After washing with IVF100 solution (Research Institute for the Functional Peptide), COCs were applied for IVF. The viability of putative zygotes was morphologically evaluated following IVF, and ones that survived were cultured in CR1aa supplemented with 5% FBS. The cleavage pattern was evaluated at 28h after IVF as follows: embryos with blastomeres of the same size without fragmentation were classified as normal cleavage; embryos with 2 blastomeres and several small fragments, direct cleavage from the 1-cell stage to 3 or 4 blastomeres, or 2 blastomeres of different size were classified as abnormal cleavage. The rates of cleavage and blastocyst formation were calculated on 2 and 8 days after culture, respectively. Total cell number and apoptosis of blastocysts were measured by terminal deoxynucleotidyl transferase dUTP nick end labelling assay. All data were obtained from more than four replicates. Viability and invitro development data were analysed using the chi-squared test. Total cell number and apoptosis data were analysed by a Student's t-test. Although no significant differences in viability, cleavage pattern, and cleavage rate (85.8 vs. 80.3%, 17.2 vs. 14.8%, and 35.4 vs. 36.7%, respectively) were observed, the developmental rate to blastocysts in the xylomannan group was significantly higher than that in the control group (68.6 vs. 42.2%; P<0.01). The present results suggest that co-incubation with xylomannan before vitrification is an effective method to improve the vitrification outcome in bovine oocytes.

Abstract
Abstract
Background
Atrial fibrillation (AF) is the most common cardiac arrhythmia, and those afflicted have reduced quality of life, functional status, and cardiac performance. The patients with AF have a high risk of coronary heart disease and cardiovascular disease. Although the prevalence of AF is increasing, cognitive disorders are also on the rise in tandem with the aging of the population. The patients with dementia have also experienced lower the quality of life and have increased mortality. Technetium 99m ECD brain perfusion single photon emission computed tomography (99mTc-ECD brain perfusion SPECT) is a useful modality for diagnosing dementia and identifying high risk patients with mild cognitive impairment. However, there are few reports about the relationship between the value of Z score calculated by 99mTc-ECD brain perfusion SPECT and prognosis of patients with AF and dementia.
Purpose
The aim of this study was to evaluate the prognostic values of brain perfusion using 99mTc-ECD SPECT in patients with AF and dementia.
Methods
Among 405 consecutive patients who were diagnosed as AF in cardiac outpatients and subsequently diagnosed as dementia using Mini-Mental State Examination by neurologists or psychiatrists, we identified 170 patients (81 ± 10 years) who underwent 99mTc-ECD brain perfusion SPECT for the current study. Of those, 73, 73, and 24 were diagnosed as Alzheimer’s dementia (AD), vascular dementia (VD), and non-specified dementia respectively. Multivariate Cox model was used to assess if higher Z score by 99mTc-ECD brain perfusion SPECT and clinical parameters were associated with major adverse cardiovascular events (MACE) including cardiac death, myocardial infarction, hospitalization for heart failure, and stroke. Sub-analyses of multivariate Cox models by AD or VD were also assessed. The cut-off values of Z score were determined using area under the curve by a receiver operating characteristic analysis based on MACE occurrences.
Results
During a mean follow-up of 1258 ± 1044 days, 62 MACE occurred. There was not significant difference of MACE between AD and VD (33%, vs. 44%, p = 0.153). By multivariable Cox model, the higher Z score of temporal-occipital-pariental lobe was associated with increased MACE compared to the lower group (HR 2.521, 95% CI 1.465–4.337, p < 0.001). In a sub-analysis of patients with AD, Z score was the most significant prognostic factor for MACE (HR 3.969, 95% CI 1.374–11.468, p = 0.011). The similar trend was observed in those with VD (HR 2.247, 95% CI 1.028–4.913, p = 0.043). Conclusion: This study demonstrated that the Z score of temporal-occipital-pariental lobe by 99mTc-ECD brain perfusion SPECT could be a potential prognostic value among patients with AF and dementia, regardless of type of dementia.

BACKGROUND Long-term efficacy and safety of ixekizumab [160 mg at week 0, then 80 mg every 2 weeks (Q2W) for 12 weeks, followed by every 4 weeks (Q4W) thereafter (i.e. Q2W/Q4W), which is the labelled psoriasis dosing where approved, except in Japan] have been established for the treatment of adults with moderate-to-severe plaque psoriasis. However, some patients may benefit from remaining on Q2W dosing beyond 12 weeks. METHODS Among patients who had static Physician's Global Assessment (sPGA) > 1 at week 12, efficacy through week 52 of continuous Q2W dosing in the IXORA-P study was compared indirectly with Q2W/Q4W in the integrated data from the UNCOVER-1, UNCOVER-2 and UNCOVER-3 studies. The continuous Q4W dose group, which had comparable results across studies, was used as the common comparator. RESULTS In the IXORA-P study, among patients with sPGA > 1 at week 12, 64% of patients in the continuous Q2W group achieved sPGA ≤ 1 at week 52, which was statistically significantly higher than the 36% of patients with sPGA > 1 in the Q2W/Q4W group based on the integrated data from the UNCOVER studies (P = 0·0007). There were no clinically meaningful differences in frequencies of safety events between patients with sPGA ≤ 1 and patients with sPGA > 1 at week 12 in the IXORA-P study. CONCLUSIONS Among patients who did not have clear or almost clear skin at week 12, nearly 30% more patients who were treated continuously with ixekizumab Q2W in IXORA-P had clear or almost clear skin at week 52 when compared indirectly with those who were treated using the labelled psoriasis dosing in integrated UNCOVER studies. What's already known about this topic? Most patients with moderate-to-severe psoriasis who were given the labelled psoriasis dosing of ixekizumab [160-mg loading dose at week 0, 80 mg every 2 weeks (Q2W) through week 12, and 80 mg every 4 weeks (QW4) thereafter] respond quickly with a high percentage of skin clearance. Additionally, patients who achieve static Physician's Global Assessment (sPGA) ≤ 1 by week 12 tend to maintain this response, even after switching to Q4W. What does this study add? Here, we assessed whether patients with sPGA > 1 at week 12 benefited from receiving more frequent dosing beyond the first 12 weeks. The results showed that Q2W dosing beyond 12 weeks resulted in more patients achieving sPGA ≤ 1 by week 52 than the labelled psoriasis dosing among patients with sPGA > 1 at week 12.

Abstract
Background The incidence of ocular candidiasis (OC) in patients with candidemia varies across different reports, and the issue of whether routine ophthalmoscopy improves outcomes has been raised. This study investigated the incidence of OC and evaluate whether the extent of OC impacts the clinical outcomes. Methods This retrospective study included non-neutropenic patients with candidemia who underwent treatment at one of 15 medical centers between 2010 and 2016. Chorioretinitis without other possible causes for the ocular lesions and endophthalmitis was classified as a probable OC. If signs of chorioretinitis were observed in patients with a systemic disease that causes similar ocular lesions, they were classified as a possible OC. Results In total, 781 of 1089 patients with candidemia underwent an ophthalmic examination. The prevalence of OC was 19.5%. The time from the collection of a positive blood culture to the initial ophthalmic examination was 5.0 ± 3.9 days in patients with OC. The leading isolate was Candida albicans (77.9%). Possible OC was associated with unsuccessful treatments (resolution of ocular findings) (odds ratio: 0.354, 95% confidence interval: 0.141–0.887), indicating an overdiagnosis in patients with a possible OC. If these patients were excluded, the incidence fell to 12.8%. Endophthalmitis and/or macular involvement, both of which require aggressive therapy, were detected in 43.1% of patients; a significantly higher incidence of visual symptoms was observed in these patients. Conclusion Even when early routine ophthalmic examinations were performed, a high incidence of advanced ocular lesions was observed. These results suggest that routine ophthalmic examinations are still warranted in patients with candidemia.

Abstract
AIM Caveolin-1 (CAV-1) is a molecule associated with endothelial cell dysfunction in chronic antibody-mediated rejection (CAMR) and considered to be a novel biomarker of CAMR. For immunohistochemical staining to reveal CAV-1 expression, most studies have used immunofluorescent stained frozen specimens, whereas formalin-fixed tissues have not been utilized. In the present study, we examined CAV-1 expression in specimens from CAMR patients using an immunoenzymatic technique with formalin-fixed tissues. METHODS Eleven patients diagnosed with CAMR based on findings of transplanted renal biopsy samples were enrolled. Those biopsy specimens were formalin fixed and stained with CAV-1 using an immunoenzymatic method. Dye extent was evaluated by classifying that in peritubular capillaries (PTC) and glomerular capillaries (GBM) in 3 steps. We then compared the Banff scores for peritubular capillaritis (ptc), glomerulopathy (cg), and C4d using those results. RESULTS CAV-1 expression was confirmed in vascular endothelium (PTC, GBM), while it was poor in epithelial cells. A Banff score for ptc and cg of 3 points was seen in 3 and 4 cases, of 2 points was seen in 1 and 4 cases, of 1 point was seen in 7 and 3 cases, and of 0 points was seen in 0 and 0 cases, respectively. In PTC, C4d and CAV-1 scores of 3 points were seen in 0 and 9 cases, of 2 points were seen in 2 and 2 cases, of 1 point was seen in 5 and 0 cases, and of 0 points were seen in 4 and 0 cases, respectively. As for GBM, C4d and CAV-1 scores of 3 points were seen in 8 and 7 cases, of 2 points were seen in 2 and 4 cases, of 1 point was seen in 0 and 0 cases, and of 0 points were seen 1 and 0 cases, respectively. CONCLUSION CAV-1 expression in PTC had a score ≥2 in all cases, indicating that an adequate level of staining of formalin-fixed tissue was attained with the present immunoenzymatic technique. These results suggest that CAV-1 expression examined by the present method may be useful for identifying endothelial dysfunction.

Abstract
This study investigates the influence of a rapid heat treatment followed by water-quenching on the mechanical properties of Ti6Al4V ELI alloy to improve its strength for use in implants. Prior to the experiment, a dilatometry test was performed to understand the progressive α-to β-phase transformation taking place during heating. The results were then used to carry out heat treatments. Microstructure was analysed using SEM, EBSD, EDX and XRD techniques. Vickers micro-hardness, tensile and high cycle rotating bending tests were used to analyse the influence of the $\alpha'$-phase fraction on the strength of the studied alloy. Results show that this process can provide a Ti6Al4V ELI alloy with a better Yield Strength (YS)/uniform deformation (εu) ratio and improved high cycle fatigue strength than those observed in the current microstructure used in medical implants. Lastly, cytotoxicity tests were performed on two types of human cells, namely MG63 osteoblast-like cells and fibroblasts. The results reveal the non-toxicity of the heat-treated Ti6Al4V ELI alloy.

Abstract
In this study, we examined whether in vivo matured oocytes collected by ovum pickup (OPU) from superstimulated Japanese black cows can improve the productivity and quality of in vitro-produced embryos. Cows in the stimulated group received an intravaginal progesterone-releasing device (Day 0), administration of 100μg of GnRH on Day 5, a single administration of 30 Armour units of FSH on the evening of Day 8 and prostaglandin F2α on the evening of Day 10. The progesterone device was removed on the morning of Day11, and then 100μg of GnRH was administered on the morning of Day 12 (0 h). The OPU and IVF were conducted at 25~26 and 30h, respectively. Cows in the control group received no treatment before OPU, and collected oocytes were subjected to in vitro maturation followed by IVF. The cortical granules distribution of oocytes at metaphase II stage, the cleavage pattern of embryos at the first cell cycle, the developmental rate, and the quality of blastocysts were compared between the stimulated and control groups. Oocytes with cortical granules distributing cortical cytoplasm were classified as normal distribution. The cleavage pattern was evaluated at 28h after IVF as follows: embryos with blastomeres of the same size without fragmentation were classified as normal cleavage; embryos with 2 blastomeres and several small fragments, direct cleavage from the one-cell stage to 3 or 4 blastomeres, or 2 blastomeres of different size were classified as abnormal cleavage. The developmental rate to blastocyst stage was measured on Day 9 of culture. The morphological quality of blastocysts was evaluated based on the IETS manual. All data were obtained from more than 3 replicates. In vitro development and cortical granules distribution data were analysed using chi-squared test. Other data were analysed using Student’s t-test. Normal cortical granules distribution rate in the stimulated group was higher than that in the control group (90.3v. 23.1%; P<0.01). Although no differences in the developmental rate to blastocyst stage (51.5v. 58.6%) was observed, the normal cleavage rate (73.4v. 51.2%) and the transferable embryo rate (98.3v. 88.0%) in the stimulated group were significantly higher (P<0.01) than those in the control group. The ratio of embryos from normal cleavage among the transferable embryos in the stimulated group was also significantly higher than in the control group (82.2v. 57.2%; P<0.01). In addition, the freezable embryo ratio (71.7v. 58.1%; P<0.072) and the total production number of embryos per head (28.0v. 15.5; P<0.106) showed a tendency to be higher in the stimulated group than in the control group. These results suggest that high quality embryos can be efficiently produced by the use of in vivo matured oocytes collected by OPU from superstimulated Japanese black cows.

Abstract
IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis, and disease recurrence often occurs after transplantation. On the other hands, Asymptomatic IgA deposition (IgAD) is occasionally observed in donated kidney. It is recognized that IgAD does not progress to IgAN, but the mechanism has not demonstrated yet. In IgAN, aberrant IgA1 O-glycan structure in the hinge region (HR) of serum IgA is suggested as one of the most convincing key mediators. However, little is known about IgA1 O-glycan structure in IgAD patients. Herein, we investigated the prevalence of IgAD in living renal transplant donors in our cohort. IgAD was observed in 21(13.0%) among 161 renal transplant donors and have statistically significant blood relationship with IgAN recipients (28.6% in relatives vs. 9.8% in non-relatives, respectively; p = 0.0073). Next, we evaluated the IgA1 O-glycan structure of serum IgA from IgAN recipients (n = 26), IgAD donors (n = 17), and non-IgAD helthy donors (n = 27) using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). The numbers of GalNAc and Gal and the Gal/GalNAc ratio in the HR of the IgAN recipients had significantly lower comparing to the IgAD and non-IgAD healthy donors. The decreased Gal/GalNAc ratio in IgAN recipients means the increased ratio of galactose-deficient IgA1. To the best of our knowledge, this is the first report to compare the O-glycan structures in IgAN recipients and IgAD donors using MALDI-TOF MS. We concluded that IgAD was more common in IgAN related donors. Overall, decreased GalNAc and Gal contents in HR could play a material pathogenic role in IgAN.

Abstract
OBJECTIVES Although amiodarone may cause neurotoxicity that can affect patient outcomes when used during cardiopulmonary resuscitation (CPR), it has been commonly prescribed during CPR. This study investigated the possible neurotoxic effects of amiodarone in a rat model of transient forebrain ischemia. DESIGN A prospective laboratory animal study was carried out. SETTING Animal laboratory. MATERIALS Male Sprague-Dawley rats. INTERVENTION Eight minutes of forebrain ischemia was induced in rats by bilateral carotid occlusion and hypotension (mean arterial pressure=35mmHg) under isoflurane (1.5%) anesthesia. Amiodarone (0, 50, 100 and 150mg/kg) with saline was injected intraperitoneally 10min after ischemia. Rats given 0mg/kg of amiodarone were used as saline-treated controls. Sham operated rats received no treatment. VARIABLES OF INTEREST Animals were evaluated neurologically on postoperative days 4-7, and histologically after a one-week recovery period. RESULTS The greatest improvement in water maze test performance corresponded to the sham operated group (p=0.015 vs. saline-treated controls). No differences in performance were seen in amiodarone-treated rats compared with saline-treated controls. In the control group, 45% of the CA1 hippocampal neurons survived, compared with 78% in the sham operated group (p=0.009). Neuron survival after ischemia in the amiodarone treatment groups (50, 100 and 150mg/kg) (58%, 40% and 36%, respectively) and in the control rats did not differ significantly. CONCLUSIONS The administration of amiodarone immediately after transient forebrain ischemia did not worsen spatial cognitive function or neuronal survival in the hippocampal CA1 region in rats. The current results must be applied with caution in humans. However, they indicate that the potential neurotoxicity induced by amiodarone during resuscitation after cardiac arrest may be negligible.
