Abstract
AIMS To evaluate the correlation between C-peptide index (CPI) at 2 h post-meal and endogenous insulin secretory capacity and to develop clinical models to predict the possibility of withdrawal from insulin therapy in patients with type 2 diabetes. METHOD This was a single-centre retrospective study of patients with type 2 diabetes admitted to our hospital. Patients were divided into a withdrawal group (n = 72) and a non-withdrawal group (n = 75) based on whether they were able to withdraw from insulin therapy at discharge, and the correlation between CPI at 2 h after meal and diabetes-related parameters was evaluated. In addition, we created two clinical models to predict the possibility of withdrawal from insulin therapy using machine learning. RESULTS The glycated haemoglobin values of the study participants were 87.8 ± 22.6 mmol/mo. The CPI at 2 h post-meal was 1.93 ± 1.28 in the non-withdrawal group and 2.97 ± 2.07 in the withdrawal group (p < 0.001). CPI at 2 h post-meal was an independent predictor of withdrawal from insulin therapy. In addition, CPI at 2 h post-meal was a better predictor than fasting CPI. Six factors associated with insulin therapy withdrawal (age, duration of diabetes, creatinine, alanine aminotransferase, insulin therapy until hospitalization, and CPI at 2 h post-meal) were used to generate two clinical models by machine learning. The accuracy of the generated clinical models ranged from 78.3% to 82.6%. CONCLUSION The CPI at 2 h post-meal is a clinically useful measure of endogenous insulin secretory capacity under non-fasting conditions.

Abstract
Introduction: Mobilization of intracellular insulin granules to the plasma membrane plays a crucial role in regulating insulin secretion. However, the regulatory mechanisms of this mobilization process have been poorly understood due to technical limitations. In this study, we propose a convenient approach for assessing intracellular insulin granule behavior based on single-molecule analysis of insulin granule membrane proteins labeled with Quantum dot fluorescent nanocrystals. Methods: This approach allows us to analyze intracellular insulin granule movement with subpixel accuracy at 33 fps. We tracked two insulin granule membrane proteins, phogrin and zinc transporter 8, fused to HaloTag in rat insulinoma INS-1 cells and, by evaluating the tracks with mean-square displacement, demonstrated the characteristic behavior of insulin granules. Results and discussion: Pharmacological perturbations of microtubules and F-actin affected insulin granule behavior on distinct modalities. Specifically, microtubule dynamics and F-actin positively and negatively regulate insulin granule behavior, respectively, presumably by modulating each different behavioral mode. Furthermore, we observed impaired insulin granule behavior and cytoskeletal architecture under chronic treatment of high concentrations of glucose and palmitate. Our approach provides detailed information regarding intracellular insulin granule mobilization and its pathophysiological implications. This study sheds new light on the regulatory mechanisms of intracellular insulin granule mobilization and has important implications for understanding the pathogenesis of diabetes.

Abstract
Do dendritic spines, which comprise the postsynaptic component of most excitatory synapses, exist only for their structural dynamics, receptor trafficking, and chemical and electrical compartmentation? The answer is no. Simultaneous investigation of both spine and presynaptic terminals has recently revealed a novel feature of spine synapses. Spine enlargement pushes the presynaptic terminals with muscle-like force and augments the evoked glutamate release for up to 20 min. We now summarize the evidence that such mechanical transmission shares critical features in common with short-term potentiation (STP) and may represent the cellular basis of short-term and working memory. Thus, spine synapses produce the force of learning to leave structural traces for both short and long-term memories.

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
Synaptic transmission involves cell-to-cell communication at the synaptic junction between two neurons, and chemical and electrical forms of this process have been extensively studied. In the brain, excitatory glutamatergic synapses are often made on dendritic spines that enlarge during learning1-5. As dendritic spines and the presynaptic terminals are tightly connected with the synaptic cleft6, the enlargement may have mechanical effects on presynaptic functions7. Here we show that fine and transient pushing of the presynaptic boutons with a glass pipette markedly promotes both the evoked release of glutamate and the assembly of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins8-12-as measured by Förster resonance transfer (FRET) and fluorescence lifetime imaging-in rat slice culture preparations13. Both of these effects persisted for more than 20 minutes. The increased presynaptic FRET was independent of cytosolic calcium (Ca2+), but dependent on the assembly of SNARE proteins and actin polymerization in the boutons. Notably, a low hypertonic solution of sucrose (20 mM) had facilitatory effects on both the FRET and the evoked release without inducing spontaneous release, in striking contrast with a high hypertonic sucrose solution (300 mM), which induced exocytosis by itself14. Finally, spine enlargement induced by two-photon glutamate uncaging enhanced the evoked release and the FRET only when the spines pushed the boutons by their elongation. Thus, we have identified a mechanosensory and transduction mechanism15 in the presynaptic boutons, in which the evoked release of glutamate is enhanced for more than 20 min.

Abstract
Clinical data on coronavirus disease-19 (COVID-19) in children during the management of nephrotic syndrome (NS) is lacking. Patients on prednisolone are compromised hosts at the risk of severe infections. Some infections may induce NS relapse. We describe the clinical course of a child with NS and COVID-19. A 3-year-old boy was admitted with clinical and laboratory findings indicative of NS. Induction therapy with prednisolone (2 mg/kg/day) induced complete remission. While tapering the dose, he was infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). He developed a high fever and periorbital edema. Urinalysis revealed proteinuria (protein-creatinine ratio: 6.3 g/gCr). He was transferred to our hospital for the concurrent management of COVID-19 and NS relapse. As proteinuria worsened, the prednisolone dose was increased to 2 mg/kg/day. Proteinuria gradually improved, and remission was noted a week after initiating full-dose steroid treatment. The fever subsided after 2 days without treatment for COVID-19. Anti-SARS-CoV-2 antibody including IgG levels decreased in the early convalescent phase. To the best of our knowledge, this is the first reported case with the recurrence of NS triggered by the SARS-CoV-2 infection in Asia. SARS-CoV-2 infection may induce NS relapse. Daily administration of full-dose of prednisolone may be effective for managing the recurrence of NS associated with SARS-CoV-2 infection.

Abstract
In diabetic pathology, insufficiency in β-cell mass, unable to meet peripheral insulin demand, and functional defects of individual β-cells in production of insulin are often concurrently observed, collectively causing hyperglycemia. Here we show that the phosphorylation of ERK1/2 is significantly decreased in the islets of db/db mice as well as in those of a cohort of subjects with type 2 diabetes. In mice with abrogation of ERK signaling in pancreatic β-cells through deletion of Mek1 and Mek2, glucose intolerance aggravates under high-fat diet-feeding conditions due to insufficient insulin production with lower β-cell proliferation and reduced β-cell mass, while in individual β-cells dampening of the number of insulin exocytosis events is observed, with the molecules involved in insulin exocytosis being less phosphorylated. These data reveal bifunctional roles for MEK/ERK signaling in β-cells for glucose homeostasis, i.e., in regulating β-cell mass as well as in controlling insulin exocytosis in individual β-cells, thus providing not only a novel perspective for the understanding of diabetes pathophysiology but also a potential clue for new drug development for diabetes treatment.

Abstract
Background Kimura’s disease (KD) is a rare chronic inflammatory disease of unknown etiology. Clinically, KD is characterized by nodular subcutaneous masses, that are typically localized to the neck and head. Involvement of the lacrimal glands and limbs is uncommon and seldom reported. Case presentation We report a case of a 4-year-old Japanese boy presenting with bilateral upper eyelid swelling with nodular subcutaneous lesions and peripheral eosinophilia. Based on clinical, histopathological, and laboratory findings, the patient was diagnosed with KD. An itchy subcutaneous mass on the left arm developed at the age of 14 years. Treatment with steroids was effective. However, as the steroids were tapered after the patient developed side effects, the masses relapsed within a few months. Treatment with cyclosporine A was then initiated, which led to an improvement of clinical features and serial levels of cytokines. Conclusions We report a rare case of KD with a peculiar clinical presentation. The patient responded well to treatment with cyclosporine A.

Abstract
This paper describes a method to estimate the direction from which the signal molecule reaches the sensor by using living cells. In this context, biohybrid sensors that utilize a sophisticated sensing system of cells can potentially offer high levels of chemical-detection sensitivity and selectivity. However, biohybrid-sensor-based chemical-source-direction estimation has not received research attention because the cellular response to chemicals has not been examined in the context of directional information. In our approach, we fabricated a device that can limit the interface between the cell-laden hydrogel and the chemical solution of interest to enhance the time difference over which the chemical solution reaches the cells. Chemical detection by cells that express specific receptors is reflected as the fluorescence of the calcium indicator within the cells. Our device has eight chambers that each house 3D cell-laden collagen hydrogels facing circularly outward. The device also works as a cover to prevent chemicals from permeating the hydrogel from above. In our study, by observing the time course of the fluorescence emission of each chamber, we were able to successfully estimate the chemical-source direction within an error range of 7–13°. Our results suggest that a combination of microstructure devices embedded with living cells can be used to exploit cell functionalities to yield chemical-source directional information.

Abstract
The criticality safety control technique is required for the fuel debris removal from the Fukushima Dai-Ichi Nuclear Power Station which experienced a severe accident. The subcriticality estimation is expected to be done with only limited information about the fuel debris while the primary containment vessel internal survey work is ongoing. The purpose of this study is to develop the subcriticality estimation method called the virtual neutron capture method. The neutrons from the surface of the fuel debris represent a major portion of detector counts. The method consists of two evaluations: the evaluation at the surface of the fuel debris for which the isotope compositions are known by fuel debris sampling and the evaluation at the region of the fuel debris for which these compositions are unknown. For the unknown composition region, the average isotope composition with arbitrary water content is given. The method surveys the relationship with the detector count and the neutron multiplication factor with any size of the unknown composition region and any ratio of the water content before the on-site evaluation. The method is verified by experiments done in the Kyoto University Critical Assembly. The method shows that the maximum difference from the reference neutron multiplication factor is 4.5 %dk. As a result, the virtual neutron capture method can be adopted to the subcriticality monitoring if the method includes the estimation margin of 4.5 %dk within the neutron multiplication factor range from 0.70 to 0.95.

Abstract
Tonsils are located mainly at the gateway of the respiratory tract, and are reportedly one of the secondary lymphatic organs of the immune system. The development of several diseases including IgA nephropathy (IgAN) is associated with inflammatory stimulation and an aberrant immune response of the tonsils. Several studies have reported an improvement in and/or an increase in the stability of the clinicopathological findings of patients with IgAN post tonsillectomy. However, the efficacy in and precise mechanism of the alleviation of symptoms of other renal diseases by tonsillectomy remain unknown. We hypothesize that tonsillectomy may play a potentially therapeutic role in renal diseases apart from IgAN, which are thought to be caused by an impaired regulation of the immune system.

Abstract
BACKGROUND Early multiple-drug therapy for severe childhood immunoglobulin A (IgA) nephropathy prevents the progression of nephritis and improves the long-term prognosis. Recent studies have focused on the relationship between the pathophysiology of IgA nephropathy and tonsillar focal infection, and the efficacy of tonsillectomy with methylprednisolone pulse therapy in children has been demonstrated. However, no study has reported on the relationship between the period from diagnosis to tonsillectomy and the long-term prognosis of IgA nephropathy. METHODS To clarify the long-term effects of an early tonsillectomy, 40 patients who were diagnosed with severe IgA nephropathy in childhood and underwent a tonsillectomy were divided into two groups based on the period from diagnosis to undergoing tonsillectomy: Group A, less than 3 years; and Group B, more than 3 years. The primary endpoint of this study was the change in the amount of proteinuria. Renal prognosis was evaluated 10 years after the diagnosis. RESULTS This study enrolled 40 patients diagnosed with severe IgA nephropathy in childhood who underwent tonsillectomy after multiple-drug therapy with/without methylprednisolone pulse therapy at Kindai University Hospital; eight patients were excluded based on the exclusion criteria. Group A consisted of 18 patients and Group B, 14 patients. Proteinuria and hematuria levels were significantly reduced in the early surgery group (P < 0.01). No significant differences were found in serum creatinine, uric acid, and IgA/C3 ratio. CONCLUSIONS High proteinuria levels worsen the renal prognosis in IgA nephropathy. Tonsillectomy in less than 3 years combined with multiple-drug therapy after the initial diagnosis could improve long-term prognosis.

Abstract
BACKGROUND The pathological findings of tonsils in IgA nephropathy include the expansion of T-cell nodules around lymphoid follicles and abnormal reticulation of the crypt epithelium in contrast to chronic tonsillitis. Recently, several studies have reported that regulatory T cells play an important role in the maintenance of self-tolerance, an abnormality that is involved in the onset of nephrotic syndrome (NS). We encountered a patient of 28-year-old male with frequently relapsing nephrotic syndrome (FRNS) and chronic tonsillitis whose tonsils demonstrated pathological findings similar to those of IgA nephropathy. CASE PRESENTATION A patient had developed NS at the age of 5 years, and was pathologically diagnosed with minimal change disease (MCD), for which he received various immunosuppressive agents as treatment for recurrence. Because tonsillitis often triggers the recurrence of NS, a tonsillectomy was performed for chronic tonsillitis at the age of 25 years. Immunohistochemical staining of his tonsils showed the expansion of CD4 positive lymphocytes around the lymphoid follicles and abnormal reticulation of the crypt epithelium. The number of peripheral blood CD4+CD25+ regulatory T cells increased, and the frequency of relapses decreased after tonsillectomy. CONCLUSION A similar self-tolerance abnormality exists in NS and IgA nephropathy; therefore, tonsillectomy might become a novel therapeutic approach for FRNS to redress the unbalanced self-tolerance and to remove the tonsillar focal infection. Further studies are necessary to verify the clinical efficiency of tonsillectomy for FRNS with recurrent episodes triggered by tonsillitis.

Abstract
The objective was to introduce a new technique for visualizing the three-dimensional (3D) movements of velopharyngeal-related muscles using high-speed cine-magnetic resonance imaging (MRI) based on T2-weighted sequences. The evaluation of phonation- and water swallowing-related events was performed in 11 healthy subjects. Specifically, whether cine-MRI could precisely visualize normal velopharyngeal function during these two events was examined. The 3D movements of the soft palate, superior pharyngeal constrictor muscles, and levator veli palatini muscles were visualized in all 11 subjects. A noteworthy finding was that the magnetic resonance signals of the superior constrictor pharyngeal muscles and the levator veli palatini muscles were significantly higher during phonation and during water swallowing than at rest. This initial study suggests that the 3D movements of velopharyngeal-related muscles can be successfully and precisely visualized without side effects. The magnetic resonance signal changes seen in the superior pharyngeal constrictor and levator veli palatini muscles using the technique described here should be useful to develop better methods of evaluation of velopharyngeal function.

Abstract
Transposition of the great arteries type I is a severe congenital heart disease that induces serious cyanosis immediately after birth and death within 24 hours, unless proper treatment is administered. A few cases have presented with reversed differential cyanosis, manifesting as separated cyanosis with high SpO 2 values in the lower limbs. However, there have been few reports of survivors of transposition of the great arteries type I presenting with reversed differential cyanosis. We experienced a case of transposition of the great arteries type I presenting with reversed differential cyanosis immediately after birth. The infant was urgently transported because of postnatal SpO 2 of 40% in the upper limbs and 90% in the lower limbs. The echocardiographic diagnosis was transposition of the great arteries type I with a narrow foramen ovale. We immediately performed balloon atrioseptostomy, and the reversed differential cyanosis was improved. The infant seems to have presented with reversed differential cyanosis because of the foramen ovale narrowing and complicating pulmonary hypertension due to fetal circulation and characteristic of transposition of the great arteries type I. Congenital heart disease, presenting with reversed differential cyanosis, is a clinical condition requiring emergency management.

Abstract
BACKGROUND Although Th2 cells are well known to play important roles in allergic diseases including allergic rhinitis (AR), the factors that induce and sustain the pathogenesis of AR remain unclear. The recent development of sublingual immunotherapy (SLIT) is expected to allow changes to the underlying pathogenesis of AR. However, which Th2 cell subsets are important in house dust mite-induced AR (HDM-AR), the influence of SLIT on the pathogenic Th2 cells, and the association of Th2 cell subsets with SLIT efficacy have not been clarified. METHODS The cytokine production and frequency of HDM-reactive T-cell subsets in peripheral blood mononuclear cells (PBMCs) were evaluated using flow cytometry in 89 HDM-AR patients (placebo [n = 43] and HDM 300 IR [n = 46]) who participated in a placebo-controlled study of SLIT with HDM tablets. All patients provided samples both before treatment as a baseline and at the end of the 52-week study. The PBMCs were stained with CellTrace™ Violet (CTV) before culture with HDM extract, and HDM-reactive T cells were detected as the proliferated cells with diminished CTV. RESULTS HDM-reactive IL-5+ IL-13+ CD27- CD161+ CD4+ cells and ST2+ CD45RO+ CD4+ cells were observed in the peripheral blood from each patient with HDM-AR; these cells significantly decreased after SLIT in the group treated with active tablets. HDM-reactive ST2+ CD45RO+ CD4+ cells were significantly lower in active-responders. CONCLUSION Allergen-reactive ST2+ CD45RO+ CD4+ cells or those combined with IL-5+ IL-13+ CD27- CD161+ CD4+ cells may be useful as markers indicating the successful treatment of SLIT. These cells may play a crucial role in the pathogenesis of AR as pathogenic memory Th2 cells.

Abstract
BACKGROUND Allergic rhinitis (AR) consists of three developmental stages that are based on the presence/absence of antigen-specific IgE and symptoms. The pathogenic Th2 (Tpath2) cells constitute a population of Th2 cells with additional potentially pathogenic characteristics. We examined the relationship between Tpath2 cells and the stages of allergic rhinitis by focusing on ST2, which is an IL-33 receptor. METHODS Patients with Japanese cedar pollen-induced AR (JCP-AR) and healthy volunteers were divided into "nonsensitized," "asymptomatic sensitized (AS)," and "JCP-AR" groups. We analyzed the ST2 expression and the Th2 function of cultured CD4+ T cells. Next, we observed the progress of patients in the AS stage around the time of seasonal pollen dispersal, with the characteristics of Th2 cells. RESULTS The ST2 expression of T cells was only upregulated in the AR group. The production of IL-4 and IL-13 was found in CD4+ T cells obtained from AS by stimulation with JCP, but reactivity to IL-33 was not observed. Although IL-33 did not induce the elevation of IL-4 production in the JCP-AR group, IL-33 substantially increased the production of IL-5 and IL-13 in comparison with antigen stimulation alone. In newly afflicted patients, the increased expression of ST2 and elevated reactivity to IL-33 was observed, even before the pollen dispersal season. CONCLUSIONS Our study demonstrated that the pathogenicity of memory Th2 cells is linked to sensitization and the stage of allergic rhinitis. Therefore, Tpath2 cells may provide useful insights into the mechanism of the onset and progression of allergic rhinitis.

Abstract
Background To elucidate the significance of absorbable surgical sutures in the occurrence of stitch abscess after surgery in patients with oral squamous cell carcinoma (SCC). Material and Methods The subjects were 251 patients who underwent excision and/or reconstruction and/or neck dissection for oral SCC using absorbable surgical sutures. Detection rates and characteristics of patients with stitch abscess were retrospectively evaluated by comparing between our present and previous data. Results There was only one stitch abscess among the 251 patients. A significant difference in the incidence of stitch abscess was found between the present data and our previous data. Of course, no significant correlations were found between the occurrence of stitch abscess using absorbable surgical sutures and the various factors seen in our previous analysis. Conclusions A complete switch of surgical sutures from silk to absorbable surgical sutures is needed for surgery in patients with oral SCC. Key words:Stitch abscess, oral cancer, occurrence, absorbable surgical sutures, silk suture.

Abstract
BACKGROUND Biomarkers that enable objective evaluation of the clinical effects of immunotherapy for allergic rhinitis have yet to be identified. METHODS This study included 40 patients who were enrolled in a large randomized, double-blind, placebo-controlled, multicenter study examining the efficacy of sublingual immunotherapy (SLIT) using Japanese cedar (JC) pollen extract during two consecutive pollen seasons from 2010 to 2012. Based on changes in total nasal symptom medication score, patients in the SLIT and placebo groups were subdivided into two subgroups: good responders and poor responders. The levels of JC pollen-specific IL-10+Foxp3+ cells and specific Th2 cytokine-producing cells were measured and the association with the efficacy of SLIT was analysed. RESULTS The total nasal symptom medication score was significantly lower in the SLIT group compared with the placebo group. The number of JC pollen-specific Th2 cytokine-producing cells increased during the pollen season in the placebo group and in poor responders in the SLIT group; however, the increases were inhibited in the good responders in the SLIT group. The number of JC pollen-specific IL-10+Foxp3+ cells increased only in these good responders. CONCLUSIONS Changes in levels of allergen-specific Th2 cytokine-producing cells and IL-10+Foxp3+ cells could be objective biomarkers for SLIT.

Abstract
Burning mouth syndrome (BMS) is an idiopathic orofacial pain condition. Although the pathophysiology of BMS is not clearly understood, central and peripheral neuropathic mechanisms are thought to be involved. The authors compared brain response to noxious heat stimuli in 16 right-handed women with primary BMS and 15 sex- and age-matched right-handed healthy female controls. A thermal stimulus sequence of 32 °C to 40 °C to 32 °C to 49 °C was repeated 4 times in a cycle. Warm and noxious heat stimuli were delivered with a Peltier thermode placed on the right palm or right lower lip for 32 s each in a session. Functional magnetic resonance imaging data were obtained by recording echoplanar images with a block design. Statistical Parametric Mapping 8 software was used to analyze the data. Patients and controls both reported feeling more pain during palm stimulation than during lip stimulation. Repetition of noxious heat stimulus on the lower lip but not on the palm induced habituation in brain activity in the cingulate cortex without reduction in pain perception. Multiple regression analysis revealed a correlation between perceived pain intensity and suppression of brain activity in the anterior cingulate cortex when the repeated thermal sequence was applied at the lower lip. Furthermore, the response of the parahippocampal area differed in BMS patients and controls when the same repeated thermal sequence was applied at the palm. The authors’ findings indicate that BMS patients show specific brain responses due to impaired function of the central and peripheral nervous systems (clinical trial registration: UMIN000015002).

Abstract
We propose a method for the production of a fiber-shaped three-dimensional (3D) cellular construct of human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs) for the quantification of the contractile force. By culturing the cardiomyocytes in a patterned hydrogel structure with fixed edges, we succeeded in fabricating hiPS-CM fibers with aligned cardiomyocytes. The fiber generated contractile force along the fiber direction due to the hiPS-CM alignment, and we were able to measure its contractile force accurately. Furthermore, to demonstrate the drug reactivity of hiPS-CM fibers, the changes in the contractile frequency and force following treatment with isoproterenol and propranolol were observed. We believe that hiPS-CM fibers will be a useful tool for pharmacokinetic analyses during drug development.

Abstract
BACKGROUND 18F-fluoro-2-deoxy-D-glucose (18F-FDG) accumulations are commonly seen in the neck-related muscles of the surgical and non-surgical sides after surgery with neck dissection (ND) for oral cancers, which leads to radiologists having difficulty in diagnosing the lesions. To examine the alterations in 18F-FDG accumulation in neck-related muscles of patients after ND for oral cancer. MATERIAL AND METHODS 18F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) in neck-related muscles were retrospectively analyzed after surgical dissection of cervical lymph nodes in oral cancers. RESULTS According to the extent of ND of cervical lymph nodes, the rate of patients with 18F-FDG-PET-positive areas increased in the trapezius, sternocleidomastoid, and posterior neck muscles of the surgical and/or non-surgical sides. In addition, SUVmax of 18F-FDG-PET-positive areas in the trapezius and sternocleidomastoid muscles were increased according to the extent of the ND. CONCLUSIONS In evaluating 18F-FDG accumulations after ND for oral cancers, we should pay attention to the 18F-FDG distributions in neck-related muscles including the non-surgical side as false-positive findings.

Abstract
BACKGROUND Biomarkers that enable objective evaluation of the clinical effects of immunotherapy for allergic rhinitis have yet to be identified. METHODS This study included 40 patients who were enrolled in a large randomized, double-blind, placebo-controlled, multicenter study examining the efficacy of sublingual immunotherapy (SLIT) using Japanese cedar (JC) pollen extract during two consecutive pollen seasons from 2010 to 2012. Based on changes in total nasal symptom medication score, patients in the SLIT and placebo groups were subdivided into two subgroups: good responders and poor responders. The levels of JC pollen-specific IL-10+Foxp3+ cells and specific Th2 cytokine-producing cells were measured and the association with the efficacy of SLIT was analysed. RESULTS The total nasal symptom medication score was significantly lower in the SLIT group compared with the placebo group. The number of JC pollen-specific Th2 cytokine-producing cells increased during the pollen season in the placebo group and in poor responders in the SLIT group; however, the increases were inhibited in the good responders in the SLIT group. The number of JC pollen-specific IL-10+Foxp3+ cells increased only in these good responders. CONCLUSIONS Changes in levels of allergen-specific Th2 cytokine-producing cells and IL-10+Foxp3+ cells could be objective biomarkers for SLIT.
