Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
PURPOSE/OBJECTIVE(S) Palliative radiotherapy is an effective and commonly used treatment for pain relief in metastatic cancer patients. This study aimed to classify the patients to predict their response to palliative radiotherapy. MATERIALS/METHODS This study used the data from our single-center, prospective observational study (UMIN000044984), which included all patients undergoing palliative radiotherapy for the painful tumor, except for postoperative setting or brain metastases. The eligibility criteria were as follows: (1) numerical rating scale (NRS) was two or more before treatment, and (2) underwent palliative radiotherapy between August 2021 and September 2022. Questionnaires for pain site, NRS, and presence/dose of opioids were obtained before, on the last day of treatment, two weeks later, one month later, three months later, and every three months after that. Patients with severe performance status (PS) were contacted by telephone. Pain response was defined to reduce NRS 2 or more at the treated site without an analgesic increase. The primary outcome was the response rate within three months of the treatment. We used multivariable logistic regression to find the independent prognostic factors for the response based on the following covariates: age, sex, PS, body mass index, NRS, history of radiotherapy, treated site, radiographic features (lytic/sclerotic/mixed), metastatic complication, presence/dose of opioids, bone-modifying agents, radiation dose, type of primary tumor, radiosensitivity, number of metastases, and days from diagnosis to treatment. A classification model was created using significant factors, and response rates were calculated for each class. Statistical significance was defined as P<0.05. RESULTS Among 488 targets of 300 patients registered, 366 targets of 261 patients met the criteria. The median age was 65 years, 44% were female, and PS (0/1/2/3/4) was 6/63/18/9/4%. The major type of tumor was gastrointestinal (32%), lung (19%), and breast (12%). Bone metastases were 75% at treated sites. Opioids were used by 72%, BMA was 27%, and chemotherapy was 50%. Re-irradiation rate was 22%. With a median follow-up of 5.8 months, 113 patients were alive, 129 had died, and 20 were lost follow-up. The average NRS was reduced from 6.1 to 3.1 from pretreatment to 3 months later per evaluable 232 targets, resulting in a pain relief rate of 60%. Opioids use (P<0.001) and re-irradiation (P<0.001) were significant factors of poor response in multivariate analysis. In our classification model, 89 targets were classified as class 1 (no opioids & no irradiation history), 211 were class 2 (other than class 1 and 3), and 66 were class 3 (opioids & re-irradiation), were 75/61/36% (P<0.001) of response rate. The 6-month cumulative pain progression rate was 12/22/32% (P<0.001), respectively. CONCLUSION Palliative radiotherapy is highly effective for patients with painful tumors especially for those without previous irradiation history or use of opioids.

Abstract
INTRODUCTION Severe asthma is associated with a serious disease burden, partially caused by limitations in activity and work impairment (1,2). AIMS AND OBJECTIVES This study aims to relate treatment with biologics targeting IL-5/5Ra to work productivity and activity in the long term in a real-world context. MATERIAL AND METHODS This is a registry-based multi-center cohort study evaluating data from adults with severe eosinophilic asthma included in the Dutch Register of Adult Patients with Severe Asthma for Optimal DIsease management (RAPSODI). Patients that started with anti-IL-5/5Ra biologics and completed the work productivity and activity improvement questionnaire, were included. Study and patient characteristics were compared between the employed and unemployed patients. Work productivity and activity impairment are related to accompanying improvements in clinical outcomes. RESULTS At baseline, 91 of 137 patients (66%) were employed which remained stable throughout the follow-up period. Patients in the working age category were younger and had significantly better asthma control (p =0.02). Mean overall work impairment due to health decreased significantly from 25.5% (SD2.6) to 17.6% (SD 2.8) during 12 months anti-IL-5/5Ra biologics treatment (P = 0.010). There was a significant association between ACQ6 and overall work improvement after targeted therapy (β =8.7, CI 2.1-15.4, P = 0.01). The improvement of asthma control of 0.5 points on the asthma Control Questionnaire was associated with an overall work impairment of - 9%. CONCLUSIONS Work productivity and activity in severe eosinophilic asthma improved after starting anti-IL-5/5Ra biologics. Clinically relevant improvement in asthma control was associated with an overall work impairment score of - 9% in this study.

Abstract
BACKGROUND Understanding patient perspectives of self-care is critical for improving multidisciplinary education programs and adherence to such programs. However, perspectives of self-care for patients with heart failure (HF) as well as the association between patient perspectives and patient-physician communication remain unclear. METHODS Confidence levels regarding self-care behaviors (eight lifestyle behaviors and four consulting behaviors) and self-monitoring were assessed using a self-administered questionnaire survey, which was directly distributed by dedicated physicians and nurses to consecutive patients hospitalized with HF in a tertiary-level hospital. Patient-physician communication was evaluated according to the quality of physician-provided information regarding "treatment and treatment choices" and "prognosis" using the Prognosis and Treatment Perception Questionnaire. Out of 202 patients, 187 (92.6 %) agreed to participate, and 176 completed the survey [valid response rate, 87.1 %; male, 67.0 %; median age, 73 (63-81) years]. Multivariate logistic regression analyses were conducted to predict low confidence in self-care (score in the lowest quartile). RESULTS High confidence (confident or completely confident >75 % of patients) was observed for all self-care behavior categories except low-salt diet (63.1 %), regular exercise (63.1 %), and flu vaccination (65.9 %). Lower confidence in self-care behavior was associated with low quality of patient-physician communication. With regard to self-monitoring, 62.5 % of patients were not confident in distinguishing worsening symptoms of HF from other diseases; non-confidence was also associated with low quality of patient-physician communication. CONCLUSIONS Hospitalized patients with HF had low confidence regarding regular exercise, salt restriction, and flu vaccination. The results also suggest patient-physician communication affects patient confidence.

Abstract
The human bronchial epithelium plays a crucial role in mediating antiviral immune reactions. When double-stranded RNA (dsRNA) binds to the receptor named Toll-like receptor (TLR) 3, activation of antiviral innate immune reactions is initiated by producing interferon (IFN) type I. Then, type I IFN promotes the transcription of IFN-stimulated genes (ISGs). Proteins encoded by ISGs reveal antiviral effects. The IFN-induced transmembrane protein 1 (IFITM1) is an ISG family member that inhibits viral infection by preventing the entry of viruses with a cell membrane. However, IFITM1 expression in human bronchial epithelium remains largely undetermined. Here, we investigated whether IFITM1 is expressed in cultured BEAS-2B bronchial epithelial cells. Polyinosinic:polycytidylic acid (poly I:C) was used for treatment of BEAS-2B as a TLR3 ligand. IFITM1 expression levels were measured using reverse transcription-quantitative PCR and Western blotting. Using RNA interference, we determined the significance of IFN-β and ISG56 on IFITM1 upregulation. Poly I:C treatment significantly upregulated IFITM1 expression in BEAS-2B cells, and it was concentration- and time-dependent. Knockdown of IFN-β or ISG56 decreased poly I:C-induced IFITM1 expression levels. Recombinant IFN-β also increased expression levels of IFITM1. In BEAS-2B cells, IFITM1 expression is upregulated by poly I:C, at least partly, via the TLR3/IFN-β/ISG56 axis. Thus, IFITM1 may contribute to antiviral innate immunity in bronchial epithelium.

Abstract
Abstract
Study question
Could autologous adipose stem cell (ASC) mitochondria supplementation restore the post-fertilization development potentialin vitrified-thawed oocytes?
Summary answer
Autologous ASC mitochondria supplementation could rejuvenate the quality of vitrified-thawed oocytes and enhance the embryo’s developmental capacity.
What is known already
Pre- and post-implantation developmental potential of embryos derived from vitrified oocytes are remarkedly lower than those of fresh oocytes. Despite its’ low efficacy, oocyte cryopreservation is becoming prevalent in assisted reproductive technologies to cater the growing demands due to patients' sociological and pathological conditions. Unfavorable effects to mitochondrial membrane potential, mitochondrial structure, ATP production, reactive oxygen species (ROS), meiotic spindle and microfilaments, and Ca2+ ion regulation are reported as detrimental damages in oocytes following the cryopreservation, that adversely affect the development potential. Furthermore, autologous stem cell mitochondria supplementation can rescue the aging-related oocyte mitochondrial damages.
Study design, size, duration
The mature oocytes, autologous ASC, and mitochondria were collected from young mice and analyzed at Osaka City University, Japan. In total, 600 young mouse mature oocytes were occupied in this prospective study.
Participants/materials, setting, methods
Young C57BL/6JJmsmouse (8weeks) mature oocytes that have been pre-vitrified were thawed before the start of the ICSI procedure.ASC specificity and ASC mitochondria function and ultrastructure were pre-analyzed. ASC mitochondria were isolated on the same day and supplemented with intracellular sperm injection (ICSI) and as the control, the mitochondrial buffer was injected. The survival rate, fertilization rate, blastulation, mitochondria function, ROS level in 2 cell embryos, and live birth rates were compared between the 2 groups.
Main results and the role of chance
The ASC mitochondriashowed higher membrane potential compared to the somatic cells and were spherical in shape with low cristae numbers. The survival rate and the fertilization ratewere comparable in both mitochondria supplemented and control groups. However, theASC mitochondria supplementation seemed to havesignificantly improvedthe blastocyst development capacity from 2cell embryos compared to the control group (P < 0.05;56.8% & 38.2%, respectively).And interestingly, a significantly higher ATP level was found in the mitochondria supplemented group’s 2 cell embryos thanin the control group (P < 0.05;905.6pmol & 561.1pmol respectively). And though it was not statistically significant, a higher potential ofgetting live birth was found in the mitochondria supplemented group thanthe control group after 2 cell embryo transfer.
Limitations, reasons for caution
We acknowledge that the absence of compared data with fresh oocytes’ ICSI, the detailed cellular mechanism behind theimprovement of embryo development, and transgenerational safety in offspring developed fromthe mitochondria supplementation werethe limitations of this study.
Wider implications of the findings
With these results, we propose that ASC mitochondria supplementation could rejuvenate the quality of cryopreserved oocytes and enhance the embryo developmental capacity, signifying another possible approach of mitochondrial transplantation therapy.

Abstract
Abstract
Study question
Does an increase of nicotinamide adenine dinucleotide (NAD+) level in oocytes lead to an improvement of blastulation after IVF?
Summary answer
The addition of NAD+ precursor to the oocyte maturation medium increased NAD+ levels in the oocytes, improving the developmental competence to the blastocyst after IVF.
What is known already
With maternal ageing, the enzyme that degrades NAD+ (CD38) increases in cells and the amount of NAD+ in cells, including oocytes, decreases. The degradation of NAD+ is also increased when cells are isolated from tissues. NAD+, which is an electron carrier used by all eukaryotes, is reduced to NADH via beta-oxidation of fatty acids and the TCA cycle, enhancing ATP synthesis in the mitochondrial electron transfer system. In addition, an enzyme in the inner mitochondrial membrane donates protons from NADH to NADP+ to synthesize NADPH, which maintains the intracellular redox state.
Study design, size, duration
This study is a prospective study using bovine oocytes retrieved from ovaries obtained from a local slaughterhouse in Osaka city. A total of 2,501 bovine oocytes were used in this study.
Participants/materials, setting, methods
Bovine cumulus-oocyte-complexes (COCs) were matured in vitro in the culture (IVM) medium supplemented with 0-100 μM nicotinamide mononucleotide (NMN). Matured oocytes were inseminated with the washed spermatozoa and cultured to assess the blastulation. Matured oocytes were also used to examine their NAD+, reactive oxygen species (ROS) and ATP levels.
Main results and the role of chance
The addition of NMN to the IVM medium increased intracellular NAD+ levels of bovine mature oocytes at 1 µM and above. As a result, it increased intracellular ATP levels and decreased ROS levels at 10 µM and above. It also improved blastocyst formation rates after IVF at 100 µM (P < 0.05; 35%) compared with control (22.2%). Moreover, the supplementation of NMN to the IVM medium decreased the percentage of apoptotic cells and intracellular ROS levels in cumulus cells surrounding oocytes.
Limitations, reasons for caution
This study was conducted in vitro using bovine oocytes. Thus, studies using human samples should be performed before clinical application.
Wider implications of the findings
By replenishing NAD+, we have found a clue to improving the IVM and IVF outcome, which has been shown to have a lower blastocyst formation rate than conventional IVF methods using in vivo matured oocytes. It may also improve the developmental potential of oocytes retrieved from older women.

Abstract
Background Sustained type I interferon (IFN) activation via Toll-like receptor (TLR) 3, 7 and 9 signaling has been reported to play a pivotal role in the development of lupus nephritis (LN). Although type I IFN activation has been shown to induce interferon-stimulated genes (ISGs) expression in systemic lupus erythematosus, the implication of ISGs expression in intrinsic glomerular cells remains largely unknown. Methods We treated cultured human glomerular endothelial cells (GECs) with polyinosinic-polycytidylic acid (poly IC), R848, and CpG (TLR3, TLR7, and TLR9 agonists, respectively) and analyzed the expression of DExD/H-Box Helicase 60 (DDX60), a representative ISG, using quantitative reverse transcription-polymerase chain reaction and western blotting. Additionally, RNA interference against IFN-β or DDX60 was performed. Furthermore, cleavage of caspase 9 and poly (ADP-ribose) polymerase (PARP), markers of cells undergoing apoptosis, was examined using western blotting. We conducted an immunofluorescence study to examine endothelial DDX60 expression in biopsy specimens from patients with LN. Results We observed that endothelial expression of DDX60 was induced by poly IC but not by R848 or CpG, and RNA interference against IFN-β inhibited poly IC-induced DDX60 expression. DDX60 knockdown induced cleavage of caspase 9 and PARP. Intense endothelial DDX60 expression was observed in biopsy specimens from patients with diffuse proliferative LN. Conclusion Glomerular endothelial DDX60 expression may prevent apoptosis, which is involved in the pathogenesis of LN. Modulating the upregulation of the regional innate immune system via TLR3 signaling may be a promising treatment target for LN.

Abstract
BACKGROUND The epidemiology of primary elbow osteoarthritis (PEOA) remains unknown. We aimed to evaluate the prevalence and associated factors of PEOA in a cross-sectional resident cohort from a municipal registry of a Japanese town. METHODS A total of 415 residents over 50 years of age were randomly sampled from a Japanese town and were adjusted for age and gender. Those with diseases that could potentially cause a secondary osteoarthritis of the elbow were excluded. The remaining 318 subjects (150 men and 168 women) underwent bidirectional radiography of the elbow. Subjects were diagnosed with PEOA if one of their elbows was Kellgren-Lawrence (KL) grade 2 or greater. In addition, motion pain and tenderness at the elbow were examined by orthopedic surgeons. Associated factors for the PEOA were statistically analyzed. RESULTS The prevalence of PEOA was 25.2% (male, 27.3%; female, 23.2%), and the prevalence of symptomatic PEOA was 0.9%. The age-stratified prevalence of PEOA was as follows: 50-59, 6.2% (male, 5.0%; female, 7.3%); 60-69, 15.4% (male, 17.5%; female, 13.7%); 70-79, 29.5% (male, 35.3%; female, 25.0%); and 80-89, 55.9% (male, 55.6%; female, 56.3%). Age and body mass index were revealed as associated factors that increased the prevalence of PEOA with KL grade 2 or greater. The use of vibrating tools was demonstrated as an independent associated factor that increased the prevalence of PEOA with KL grade 4 in addition to the 2 aforementioned factors. CONCLUSIONS The prevalence of PEOA in Japanese subjects was 25.2% for those aged 50-89 years with a mean age of 69.2 years, most of which was asymptomatic OA without motion pain or tenderness at the elbow. Age and body mass index increased the prevalence of PEOA with KL grade 2 or greater. The prevalence of PEOA increased with age, but the disease was self-accommodated by most people.

Abstract
In legume–rhizobia symbiosis, partner recognition and the initiation of symbiosis processes require the mutual exchange of chemical signals. Chemicals, generally (iso)flavonoids, in the root exudates of the host plant induce the expression of nod genes in rhizobia, and, thus, are called nod gene inducers. The expression of nod genes leads to the production of lipochitooligosaccharides (LCOs) called Nod factors. Natural nod gene inducer(s) in Lotus japonicus–Mesorhizobium symbiosis remain unknown. Therefore, we developed an LCO detection method based on ultra-high-performance liquid chromatography–tandem-quadrupole mass spectrometry (UPLC-TQMS) to identify these inducers and used it herein to screen 40 phenolic compounds and aldonic acids for their ability to induce LCOs in Mesorhizobium japonicum MAFF303099. We identified five phenolic acids with LCO-inducing activities, including p-coumaric, caffeic, and ferulic acids. The induced LCOs caused root hair deformation, and nodule numbers in L. japonicus inoculated with M. japonicum were increased by these phenolic acids. The three phenolic acids listed above induced the expression of the nodA, nodB, and ttsI genes in a strain harboring a multicopy plasmid encoding NodD1, but not that encoding NodD2. The presence of p-coumaric and ferulic acids in the root exudates of L. japonicus was confirmed by UPLC-TQMS, and the induction of ttsI::lacZ in the strain harboring the nodD1 plasmid was detected in the rhizosphere of L. japonicus. Based on these results, we propose that phenolic acids are a novel type of nod gene inducer in L. japonicus–Mesorhizobium symbiosis.

Abstract
Recent studies have revealed the importance of cell membrane stability in normal cell function. Sphingomyelin phosphodiesterase acid-like 3b (SMPDL3b), a lipid modifying enzyme that converts sphingomyelin to ceramide in the cell membrane, is expressed in macrophages and regulates Toll-like receptor (TLR) 4 signaling by altering cell membrane fluidity. SMPDL3b is also expressed in human podocytes, which are involved in the pathogenesis of several glomerular diseases such as diabetic kidney disease, focal segmental glomerulosclerosis, and idiopathic nephrotic syndrome in children; however, the role of SMPDL3b in podocyte innate immunity is unclear. As podocytes are equipped with innate immune systems including TLR3, and viral infections often exacerbate proteinuria in children with idiopathic nephrotic syndrome, we hypothesized that changes in SMPDL3b expression levels could affect anti-viral responses via TLR3 signaling in podocytes, consequently impairing normal podocyte function. To examine the role of SMPDL3b in TLR3 signaling in podocytes, we treated conditionally immortalized human podocytes with polyinosinic-polycytidylic acid (poly IC), to activate TLR3 signaling. The cells were then transfected with small interfering RNA against SMPDL3b. Poly IC activated the TLR3 pathway, whereas knockdown of SMPDL3b attenuated poly IC-induced interferon-β/chemokine C-X-C ligand 10 expression in podocytes. To our knowledge, this is the first report demonstrating SMPDL3b involvement in podocyte innate immunity; these results suggest that SMPDL3b is essential for adequate anti-viral responses in podocytes, possibly by modulating lipid metabolism in the cell membrane.

Abstract
[Purpose] Excessive reactive oxygen species (ROS) induced by prolonged high-intensity exercise can cause structural and functional damage. Antioxidant polyphenol supplementation, which reduces ROS levels, may improve high-intensity exercise performance. We evaluated the effect of lychee fruit extract, which contains high levels of low-molecular-weight oligomerized polyphenols, on high-intensity exercise performance. [Methods] Ten male athletes were included in an open-label trial that consisted of control and intervention phases, with a 7-day washout period between phases. The participants were administered oligomerized lychee fruit extract for seven days, whereas no intervention was given in the control phase. High-intensity intermittent exercise and the Wingate test were performed. The power output, blood lactate levels, reactive oxygen metabolite levels, biological antioxidant potential, heart rate, and rate of perceived exertion were measured. [Results] The average power output was significantly higher in the intervention phase than in the control phase (P < 0.01), while the change in blood lactate levels was significantly lower in the intervention phase than in the control phase (P < 0.05). The average heart rate was significantly higher in the intervention phase than in the control phase (P < 0.05), without changing the rate of perceived exertion. Although there was no difference in reactive oxygen metabolite levels between the phase, the change in biological antioxidant potential was larger in the intervention phase than in the control phase (P = 0.06). The Wingate test showed no significant differences between the phase. [Conclusion] Short-term loading with oligomerized lychee fruit extract may increase performance during high-intensity intermittent exercise by improving metabolism.

Abstract
Root nodule symbiosis between legumes and rhizobia involves nitric oxide (NO) regulation by both the host plant and symbiotic rhizobia. However, the mechanisms by which the rhizobial control of NO affects root nodule symbiosis in Lotus japonicus are unknown. Therefore, we herein investigated the effects of enhanced NO removal by Mesorhizobium loti on symbiosis with L. japonicus. The hmp gene, which in Sinorhizobium meliloti encodes a flavohemoglobin involved in NO detoxification, was introduced into M. loti to generate a transconjugant with enhanced NO removal. The symbiotic phenotype of the transconjugant with L. japonicus was examined. The transconjugant showed delayed infection and higher nitrogenase activity in mature nodules than the wild type, whereas nodule senescence was normal. This result is in contrast to previous findings showing that enhanced NO removal in L. japonicus by class 1 phytoglobin affected nodule senescence. To evaluate differences in NO detoxification between M. loti and L. japonicus, NO localization in nodules was investigated. The enhanced expression of class 1phytoglobin in L. japonicus reduced the amount of NO not only in infected cells, but also in vascular bundles, whereas that of hmp in M. loti reduced the amount of NO in infected cells only. This difference suggests that NO detoxification by M. loti exerts different effects in symbiosis than that by L. japonicus.

Abstract
BACKGROUND Glomerular endothelial cells (GECs) are directly exposed to circulating viral particles in the glomerulus. Although viral infections may trigger the development of acute kidney injury or the worsening of pre-existing chronic kidney disease, the specific molecular mechanisms underlying antiviral reactions via the activation of endothelial Toll-like receptor 3 signaling in the kidney remain to be determined. Interferon (IFN)-induced transmembrane protein 1 (IFITM1), a member of interferon-stimulated gene protein family, is involved in the prevention of viral entry into cerebral vascular endothelial cells, respiratory epithelial cells, and endometrium. However, as far as we are aware, the implication of IFITM1 associated with viral infections in GECs has not been investigated to date. METHODS Cultured, normal human GECs were treated with polyinosinic-polycytidylic acid (poly IC), a synthesized viral double-stranded RNA, then the expression of IFITM1 was examined by quantitative real-time reverse transcription-polymerase chain reaction and western blotting. To further elucidate the poly IC-induced signaling pathway, the cells were applied to RNA interference against IFN-β, nuclear factor-κB p65, and IFN regulatory factor 3. We also conducted an immunofluorescence study to examine endothelial IFITM1 expression in biopsy specimens from patients with chronic kidney disease. RESULTS We found that the activation of Toll-like receptor 3 induced endothelial expression of IFITM1, and that this involved IFN regulatory factor 3 and IFN-β, but not nuclear factor-κB. Intense endothelial IFITM1 immunoreactivity was observed in biopsy specimens from patients with lupus nephritis. CONCLUSIONS Antiviral reaction-related endothelial expression of IFITM1 may be involved, at least in part, in the development of particularly in lupus nephritis. Further detailed studies of the implication of interferon stimulated genes, including IFITM1 in GECs are needed.

Abstract
The pathogenesis of heart failure with preserved ejection fraction (HFpEF) in obese diabetic patients has been implicated in metainflammation. Increased expression of inducible nitric oxide synthase (iNOS) and dysfunction of the unfolded protein response (UPR), especially inositol-requiring enzyme 1α-X-box binding protein 1 (IRE1α-Xbp1s) signaling in the heart, have been associated with HFpEF. We investigated the effect of imeglimin, a potential new treatment for type 2 diabetes, on the pathogenesis of HFpEF. We induced obesity, impaired glucose tolerance, and cardiac hypertrophy with fibrosis, fat accumulation, and diastolic dysfunction in wild-type mice with a high-fat diet (HFD) and the nitric oxide synthase (NOS) inhibitor l-NAME for 16 weeks. Treatment with imeglimin starting at 10 weeks not only improved their abnormal systemic glucose metabolism and visceral obesity but also their cardiac abnormalities. We found that imeglimin suppressed the upregulation of iNOS, and restored the expression of Xbp1s and the expression of the E3 ubiquitin ligase STIP1 homology and U-box-containing protein 1 (STUB1), which is responsible for the degradation of Forkhead box protein O1 (FoxO1), a direct transcriptional target of Xbp1s. It also suppressed the excessive transcriptional activity of FoxO1, which is located downstream of Xbp1s and is involved in the form development of HFpEF and cardiac adipogenesis. Imeglimin also restored the expression of Glutathione peroxidase 4 (GPX4), which protects cells against excess lipid peroxidation and governs a novel form of programmed cell death, called ferroptosis.

Abstract
INTRODUCTION Various viruses including a novel coronavirus (SARS-CoV-2) can infect the kidney. When viruses invade the glomeruli from the bloodstream, glomerular endothelial cells (GECs) initiate the innate immune reactions. We investigated the expression of interferon (IFN)-induced protein with tetratricopeptide repeats (IFIT) 1/2/3, antiviral molecules, in human GECs treated with a toll-like receptor (TLR) 3 agonist. Role of IFIT1/2/3 in the expression of C-X-C motif chemokine ligand 10 (CXCL10) was also examined. METHODS Human GECs were cultured and stimulated with polyinosinic-polycytidylic acid (poly IC), a synthetic TLR3 agonist. Real-time qPCR, Western blotting, and ELISA were used to examine the expression of IFIT1/2/3, IFN-β, and CXCL10. RNA interference against IFN-β or IFIT1/2/3 was also performed. RESULTS Expression of IFIT1/2/3 and CXCL10 was induced by poly IC in GECs. The inductions were inhibited by RNA interfering of IFN-β. Knockdown of IFIT1/2/3 decreased the CXCL10 expression. Knockdown of IFIT3 decreased the expression of IFIT1 and IFIT2 proteins. CONCLUSION IFIT1/2/3 and CXCL10 were induced by poly IC via IFN-β in GECs. IFIT1/2/3 may increase the expression of CXCL10 which induces lymphocyte chemotaxis and may inhibit the replication of infected viruses. These molecules may play a role in GEC innate immune reactions in response to viruses.

Abstract
Abstract
Background
In conjunction with fractional flow reserve (FFR), our previous study has shown the accuracy and utility of saline induced Pd/Pa ratio (SPR) for the assessment of myocardial ischemia. However, the potential mechanism how saline injection leads to increase in coronary flow remains speculative.
Purpose
This study aimed to clarify the underlying mechanism of SPR by using swine models.
Methods
The study was conducted in four swine models, and bolus of 25°C saline, 40°C saline, and 25°C dextran was injected at rates of 40mL/5sec through a catheter inserted into the superior mesenteric artery. Its peripheral arterioles were observed and recorded by a digital microscope, and transit time of each fluid and a luminal diameter of arterioles before and after injection were measured.
Results
The result from arterioles diameters of pre- and post-injection (0.049±0.016mm vs. 0.050±0.016mm; P=0.636) indicated that luminal diameters remained unchanged regardless of fluid administration. The transit time of 25°C saline was significantly shorter than 25°C dextran (3.19±0.68sec vs. 6.15±1.19sec; P<0.0001). Although the result showed no significance, the transit time of 40°C saline with lower viscosity was shorten compared to 25°C saline (3.1±0.43sec vs. 3.65±0.46sec; P=0.088).
Conclusions
Compared to 25°C dextran (viscosity of 4.991mPa·s) having the same viscosity as 37°C whole blood, 25°C saline (viscosity of 1.012mPa·s) caused increasing to double the intravascular flow volume without dilating arterioles. The results strongly suggested that the potential mechanism of SPR was viscosity reduction effect. Combined with FFR which is based on vasodilation-mediated hyperemia, these findings may contribute to clarifying the pathophysiology and especially the microcirculation in coronary artery diseases.

Abstract
Abstract
Background
The effective treating method of coronary side branch lesions such as ostial stenosis or thin arteries has not been established. On the other hand, tortuous side branch rarely has stenotic lesions.
Purpose
We focused on coronary side branches on the ventricular free wall, and examined coronary risk factors and bending and stretching motion of branch which can contribute to the development of atherosclerotic lesion.
Methods
In elective and first-time coronary angiograms, we included side branches on the ventricular free wall (>2mm in diameter) and excluded previously treated ones. Study A; we divided arteries into proximal, middle, and distal segment, and examined the presence of tortuosity and stenotic lesions exceeding 50% diameter stenosis (DS) for each segment. A score of 1 was assigned to tortuous segment, and 0 to non-tortuous one. Study B; we included stenotic lesion (>50% DS) in side branch ostium and excluded those extended across main coronary arteries. Relation between lesions and patients' characteristics was examined.
Results
Study A; in 1,828 side branches from 472 patients, middle and distal segments had significantly higher tortuosity score than proximal (0.68, 0.78 vs. 0.34; p<0.0001). On the contrary, proximal segments had more stenotic lesions except ostial stenosis (230 vs. 69, 5; p<0.0001). Study B; in 1,740 side branches from 465 patients, 122 ostial stenotic lesions were found (7.0%). Multivariate logistic regression analysis revealed diabetes mellitus and age as independent contributors to development of ostial stenosis (Table).
Conclusions
Side branch stenosis developed less frequently in middle and distal segments, where stronger ventricular wall motion reinforces bending and stretching motion and tortuosity of arteries. This fact indicates that those characteristics may prevent developing atherosclerosis through increasing shear stress. On the other hand, diabetes mellitus strongly contributes to the development of ostial stenosis. Thus, the developing mechanism of atherosclerotic lesion in side branch on the ventricular free wall differs by the location of lesion.

Abstract
BACKGROUND/AIM Adult T-cell leukemia (ATL) is a hematological malignancy caused by infection with human T-cell leukemia virus type 1 (HTLV-1). Chemotherapy, antibody therapy, and bone marrow transplantation are used to treat this disease, however, median survival time has not been significantly improved. Our aim was to develop and evaluate a novel antibody-drug conjugate (ADC) with regards to cell cytotoxicity and target specificity. MATERIALS AND METHODS In this study, we have constructed a novel ADC, which is composed of an anti-CD70 single chain Fv-Fc antibody conjugated with the anticancer agent emtansine using a novel antibody modification method. Cell cytotoxicity and target specificity were assessed using a cell proliferation assay. RESULTS The anti-CD70 ADC selectively killed HTLV-1-infected cells and ATL cells without affecting other cells. CONCLUSION The anti-CD70 ADC offers some chemotherapeutic potential for the treatment of ATL.

Abstract
Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy worldwide, but there are few reports investigating its prevalence using subjects diagnosed by both clinical symptoms and nerve conduction studies (NCSs) in a population-based cohort. This study aimed to determine the epidemiology of CTS diagnosed by sensory disturbance findings and NCSs using a randomly sampled resident population. Methods: Subjects aged between 50 and 89 years were randomly sampled from the basic resident registry of a rural Japanese town. Subjects indicating a history of CTS surgery in a written questionnaire were classified as having past CTS. Subjects with both sensory disturbance of the median nerve area and delays in NCSs were diagnosed as having present CTS. Subjects with past or present CTS were judged as affected with CTS. We calculated the prevalence of CTS and investigated for possible risk factors. Results: Seventeen subjects (14 female and 3 male) were affected with CTS among 379 enrolled subjects. Adjusting these results to Japanese population values, the weighted prevalence of CTS was 4.7% (female: 7.2%, male: 1.8%) in the Japanese population aged 50 to 89 years. Statistically significant positive correlations were found between CTS and female, higher BMI, rheumatoid arthritis, and trigger digit. In females affected with CTS, third metacarpal length was significantly shorter than in those without CTS. Conclusions: This epidemiological study clarified the prevalence of CTS among Japanese seniors as 4.7%. Female, higher BMI, rheumatoid arthritis, trigger digit, and shorter third metacarpal length in females were risk factors for CTS.

Abstract
The rhizobial type III secretion system secretes effector proteins into host plant cells, which may either promote or inhibit symbiosis with legumes. We herein demonstrated that the type III secretion system of Bradyrhizobium sp. SUTN9-2 obstructed symbiosis with Lotus japonicus Miyakojima, L. japonicus Gifu, and Lotus burttii. A mutant of SUTN9-2 that is unable to secrete effector proteins showed better nodulation and plant growth promotion than wild-type SUTN9-2 when paired with these Lotus spp. We propose that SUTN9-2 is a useful strain for understanding the mechanisms by which effector proteins obstruct symbiosis between Bradyrhizobium and Lotus spp.

Abstract
PURPOSE To examine the stability of the articular reduction 12 weeks after intra-articular distal radius fracture (DRF) fixation with a volar locking plate (VLP). METHODS We prospectively assessed for losses in articular reduction, including gap and step, during the 12 weeks following surgery for intra-articular DRF treated with a VLP in 68 wrists. The mean patient age was 62 years (range, 16-88 years). Frontal and lateral digital tomosynthesis, a recently developed form of digital tomography, was employed to measure articular gap and step in the lunate and scaphoid fossa of the radius. The average time between surgery and imaging was 1.2 days (range, 0-2 days) for the first evaluation and 87.0 days (range, 74-105 days) for the second examination. RESULTS The mean gap and step were similar at the first and second examinations: 0.4 mm (SD, 0.8) and 0.3 mm (SD, 0.6) and 0.3 mm (SD, 0.7) and 0.3 mm (SD, 0.5), respectively. CONCLUSIONS There was no change in the alignment of the fragments in cases treated with VLP. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic II.

Abstract
Bradyrhizobium sp. strain SUTN9-2 is a symbiotic and endophytic diazotrophic bacterium found in legume and rice plants and has the potential to promote growth. The present results revealed that SUTN9-2 underwent cell enlargement, increased its DNA content, and efficiently performed nitrogen fixation in response to rice extract. Some factors in rice extract induced the expression of cell cycle and nitrogen fixation genes. According to differentially expressed genes (DEGs) from the transcriptomic analysis, SUTN9-2 was affected by rice extract and the deletion of the bclA gene. The up-regulated DEGs encoding a class of oxidoreductases, which act with oxygen atoms and may have a role in controlling oxygen at an appropriate level for nitrogenase activity, followed by GroESL chaperonins are required for the function of nitrogenase. These results indicate that following its exposure to rice extract, nitrogen fixation by SUTN9-2 is induced by the collective effects of GroESL and oxidoreductases. The expression of the sensitivity to antimicrobial peptides transporter (sapDF) was also up-regulated, resulting in cell differentiation, even when bclA (sapDF) was mutated. This result implies similarities in the production of defensin-like antimicrobial peptides (DEFs) by rice and nodule-specific cysteine-rich (NCR) peptides in legume plants, which affect bacterial cell differentiation.

Abstract
Background
Brugada syndrome (BrS) has been characterized by no apparent structural abnormalities in both ventricles, but, recently, the presence of subtle right ventricular (RV) structural abnormalities in patients with BrS has been reported.
Purpose
The aim of this study was to evaluate the occurrence of RV dysfunction in patients with BrS and their characteristics.
Methods
We enrolled 49 consecutive patients (54 ± 11 years old) diagnosed with Brs and underwent echocardiography from 2017 to 2018. The echocardiographic parameters and electrophysiological examinations were evaluated including RV size and function such as RV outflow and inflow tract diameter, TAPSE, S’, and FAC. Abnormality threshold for parameters of RV dysfunction is defined as followed: a TAPSE of <17 mm, an S’ of <9.5 cm, and an FAC of <35%.
Results
Among 49 patients, one patient showed a TAPSE of <17 mm, 5 patients an S’ of <9.5 cm, and 10 patients an FAC of <35%. Evaluating characteristics of Brs patients with RV dysfunction, all patients were divided into 2 groups by the value of RV FAC; 39 patients showing FAC >35% (group A), 10 patients FAC ≤35% (group B). The comparison of each parameter between 2 groups is shown in Table. TAPSE and S’ in group B were lower than in group A. RV inflow tract diameter in group B was larger than in group A, although there was no differences in RV out tract diameter. There were no significant differences in left ventricular parameters, and grade of tricuspid regurgitation. QRS duration prolonged and the rate of ICD implantation was higher in group B than in group A. Moreover, all patients in group B showed RV wall motion abnormalities and the distribution was as followed: diffuse (n = 2), RV mid (n = 2), RV apex (n = 6).
Conclusions
BrS patients frequently showed RV dysfunction during follow-up, and it may be related to the prolongation of QRS duration. We should pay much attention to the occurrence of RV dysfunction in follow-up echocardiography.

Abstract
The nifV gene encodes homocitrate synthase, the enzyme that catalyzes the formation of homocitrate, which is essential for arranging the FeMo-cofactor in the catalytic center of nitrogenase. Some host plants, such as Lotus japonicus, supply homocitrate to their symbionts, in this case, Mesorhizobium loti, which lacks nifV. In contrast, Bradyrhizobium ORS285, a symbiont of Aeschynomene cross-inoculation (CI) groups 2 and 3, requires nifV for symbiosis with Aeschynomene species that belong to CI group 3, and some species belonging to CI group 2. However, it currently remains unclear whether rhizobial nifV is required for symbiosis with Aeschynomene species belonging to CI group 1 or with other legumes. We generated nifV-disruption (ΔnifV) mutants of two wide-host-range rhizobia, Bradyrhizobium SUTN9-2 and DOA9, to investigate whether they require nifV for symbiosis. Both ΔnifV mutant strains showed significantly less nitrogenase activity in a free-living state than the respective wild-type strains. The symbiotic phenotypes of SUTN9-2, DOA9, and their ΔnifV mutants were examined with four legumes, Aeschynomene americana, Stylosanthes hamata, Indigofera tinctoria, and Desmodium tortuosum. nifV was required for the efficient symbiosis of SUTN9-2 with A. americana (CI group 1), but not for that of DOA9. SUTN9-2 established symbiosis with all three other legumes; nifV was required for symbiosis with I. tinctoria and D. tortuosum. These results suggest that, in addition to Aeschynomene CI groups 2 and 3, CI group 1 and several other legumes require the rhizobial nifV for symbiosis.

Abstract
BACKGROUND While limb elevation and other methods for reducing hand edema are commonly used in clinical practice, alternative methods, such as compression and venous perfusion assist system (VPAS), have emerged. This study compared the efficacy of VPAS to limb elevation in decreasing hand edema after surgery for distal radial fracture (DRF) treated by a volar locking plate (VLP). METHODS A randomized controlled trial was conducted in 102 patients to compare VPAS and elevation methods for edema reduction following VLP fixation for DRF. Changes in edema were measured using the tape measure method along with other parameters on the next day and at one, three, six, and 12 weeks postoperatively. RESULTS There were no significant differences in edema reduction or other factors between the VPAS and elevation groups at any measurement point. CONCLUSIONS VPAS appears to confer no measurable advantage over management with elevation for edema reduction after VLP fixation of DRF. TRIALS REGISTRY This study was registered at the University Hospital Medical Information Network Clinical Trials Registry (UMIN000015640).

Abstract
Bradyrhizobium sp. strain SUTN9-2 was confirmed as rice endophytic bacteria and also as rice growth promotion agent. SUTN9-2 showed the capability of plant growth promotion characteristics, such as indole-3-acetic acid (IAA) and 1-amino-cyclopropane-1-carboxylic acid (ACC) deaminase productions and nitrogen fixation. In this study, the ability of SUTN9-2 to stimulate rice growth was investigated at different stages with N-free and NH4 NO3 under in vivo condition. The rice dry weight and chlorophyll content could be enhanced when SUTN9-2 was inoculated in N-free, especially at seedling stage (7 and 14 dai). The rice dry weight was also increased when SUTN9-2 was inoculated with NH4 NO3 at 7 and14 dai. The results of quantitative analysis of IAA and ACC deaminase were inconsistent with the expression of genes involved in IAA (nit) and ACC deaminase (acdS) productions. This inconsistently could implied that IAA and ACC deaminase produced from SUTN9-2 do not directly affect rice growth, but other factors resulting from the production of IAA and ACC deaminase could be involved. Moreover, the expression of genes involved in nitrogen fixation (nifH and nifV) of SUTN9-2 was also induced in rice tissues. This finding suggested that rice growth promotion may be supported by NH4 NO3 together with nitrogen fixation by SUTN9-2. SIGNIFICANCE AND IMPACT OF THE STUDY: Indole-3-acetic acid, 1-amino-cyclopropane-1-carboxylic acid deaminase productions and nitrogen fixation may play important roles in rice growth promotion by endophytic SUTN9-2, especially at early rice seedling growth stage, which has the potential to be used as rice seedling growth promoter in the system of rice intensification.
