Spinal pituitary adenylate cyclase-activating polypeptide and PAC1 receptor signaling system is involved in the oxaliplatin-induced acute cold allodynia in mice.

Chemotherapy-induced peripheral neuropathy (CIPN) is a type of peripheral neuropathy that develops in patients treated with certain anticancer drugs. Oxaliplatin (OXA) causes CIPN in approximately 80-90 % of patients; thus, it is necessary to elucidate its underlying mechanism and develop effective treatments and prevention methods. The purpose of this study was to determine whether the pituitary adenylate cyclase-activating polypeptide (PACAP)/PAC1 receptor system in the spinal dorsal horn is involved in OXA-induced acute cold allodynia and examine the effect of a PAC1 receptor antagonist.

Effect of short foot exercise on lower-limb motor control function during single-leg standing in university students with flatfoot: A randomized controlled trial.

Introduction: Intrinsic foot muscles (IFMs) play an important role in lower-limb motor control, including biomechanics and neuromuscular control function. Short foot exercise (SFE) and toe curl exercise (TC) are methods used to train the IFMs, but their effect on lower-limb motor control has not been reported in previous studies. This study evaluated the effects of SFE and TC on lower-limb motor control function during single-leg standing (SLS).

Group2 innate lymphoid cells ameliorate renal fibrosis and dysfunction associated with adenine-induced CKD.

Renal fibrosis is a common pathway of chronic kidney disease (CKD) progression involving primary kidney injury and kidney diseases. Group 2 innate lymphoid cells (ILC2s) mediate type 2 immune responses irrespective of antigen presentation and play a reno-protective role in kidney injury and disease. In the present study, we observed a decrease in kidney-resident ILC2s in CKD and found that enrichment of ILC2s in the kidney ameliorates renal fibrosis.

In vitro investigation of the effects of Lactobacillus delbrueckii ssp. bulgaricus OLL1073R-1 exopolysaccharides on tight junction damage caused by influenza virus infection.

It is a problem that influenza virus infection increases susceptibility to secondary bacterial infection in lungs leading to lethal pneumonia. We previously reported that exopolysaccharides (EPS) derived from Lactobacillus delbrueckii ssp. bulgaricus OLL1073R-1 (OLL1073R-1) could prevent against influenza virus infection followed by secondary bacterial infection in vitro.

Case of persistent corneal epithelial damage after cataract surgery leading to diagnosis of vitamin A deficiency.

Purpose: To report our findings of reduced full-field electroretinograms (ff-ERGs) and abnormal optical coherence tomographic (OCT) images in a patient with poor visual acuity after cataract surgery who was eventually diagnosed with vitamin A deficiency (VAD).

Methods: This was a clinical study of a patient who complained of blurred vision after cataract surgery. To determine the cause of the reduced vision, we recorded full-field electroretinograms (ff-ERGs) to determine the scotopic and photopic status of the retina.

Subclinical Ocular Changes after Intravitreal Injections of Different Anti-VEGF Agents for Neovascular Age-Related Macular Degeneration.

Intraocular inflammations (IOIs) have been reported to occur after intravitreal injections of brolucizumab, and one of their causes has been suggested to be drug-specific features. We evaluated the anterior chamber by the aqueous flare value (AFV) and the retina by flicker electroretinography (ERG) after the initial intravitreal injection of aflibercept (IVA), brolucizumab (IVBr), or faricimab (IVF) for neovascular age-related macular degeneration (nAMD). The AFV and flicker ERGs were determined before, 2 weeks after, and 4 weeks after the injections in 14 eyes of 14 patients for each drug.

Exploring the significance of interleukin-33/ST2 axis in minimal change disease.

Minimal change disease (MCD), a common cause of idiopathic nephrotic syndrome, has been postulated to exhibit an association with allergic conditions. Recent studies revealed the crucial role of interleukin (IL)-33 in type 2 innate immunity. We hypothesized that development of MCD involves an IL-33-related immune response.

The essential role of intestinal microbiota in cytomegalovirus reactivation.

Human cytomegalovirus (HCMV) is a member of Herpesviridae. It has been reported that HCMV is reactivated in the breast milk of HCMV-seropositive lactating women. As we have reported various aspects of the roles of indigenous microbiota, its role in the murine CMV (MCMV) reactivation was examined in this study.

Methods: Five-week-old male Balb/c (wild-type; WT) or CD1dKO mice were fed with control-diet (CTD) or HFD for 16 weeks.

Results: The present study revealed four main findings.

Totally endoscopic pulmonary valve replacement.

A 68-year-old man with a history of valve-sparing aortic root replacement and endoscopic aortic valve replacement was admitted to our hospital with dyspnea. Transthoracic echocardiography revealed severe pulmonary valve regurgitation. The patient had undergone cardiac surgery twice, through median sternotomy and right thoracotomy; therefore, we planned endoscopic pulmonary valve replacement the left thoracic approach.

HIF-PHD inhibitor regulates the function of group2 innate lymphoid cells and polarization of M2 macrophages.

Hypoxia-inducible factor-prolyl hydroxylase (HIF-PHD) inhibitors are therapeutic agents for renal anemia that work through HIF2-mediated upregulation of erythropoietin (EPO) and have also been reported to suppress renal fibrosis. Group 2 innate lymphoid cells (ILC2s) have been proven to be involved in the pathogenesis of fibrosis in various organs, including the kidney. However, the relationship between the HIF pathway, renal fibrosis, and kidney ILC2s remains unclear.

Participants: Thirty patients who underwent cataract surgery.

Low-magnification narrow-band imaging for small gastric neoplasm detection on screening endoscopy.

Background And Aims: Microsurface patterns of the gastric mucosa can be observed using magnifying narrow-band imaging (M-NBI). However, the efficacy of M-NBI at low-magnification (LM-NBI) screening for detecting small gastric neoplasms is unclear.

Methods: This prospective study was conducted at a single institution.

IL-33 attenuates renal fibrosis via group2 innate lymphoid cells.

Renal fibrosis is a common pathway in the progression of various kidney diseases and injuries. Unilateral ureteral obstruction (UUO) induces renal fibrosis, and immune responses profoundly affect its pathogenesis. Group2 innate lymphoid cells (ILC2s) are strongly activated by interleukin (IL) -33, which is a member of IL-1 family and recognize as alarmin.

Design and synthesis of pyrido[2,3-d]pyrimidine derivatives for a novel PAC1 receptor antagonist.

Since PA-8 (5-(4-(Allyloxy)-3-methoxyphenyl)-2-amino-5,8-dihydro-3H,6H-pyrido[2,3-d]pyrimidine-4,7-dione) was recently identified as a novel small-molecule antagonist of the pituitary adenylate cyclase-activating polypeptide (PACAP) type I (PAC1) receptor, a series of pyrido[2,3-d]pyrimidine derivatives have been designed, synthesized and subsequently evaluated for antagonistic activity on the PAC1 receptor. In this study, we synthesized 21 derivatives based on the PA-8 structure. Among them, the compound 2o (2-Amino-5-(3-trifluoromethoxy-phenyl)-5,8-dihydro-3H,6H-pyrido[2,3-d]pyrimidine-4,7-dione) showed more potent antagonistic activities than PA-8.

Impact of pain in other body regions on the foot-specific quality of life in patients with hallux valgus.

Objectives: The purpose of this study was to clarify the prevalence of pain outside the foot, and to determine the associations of pain outside the foot with foot-specific quality of life (QOL) in patients with hallux valgus.

Methods: Patients scheduled to undergo hallux valgus surgery were recruited. Patients answered whether they experienced disabling pain in 13 body regions other than the foot.

Exopolysaccharides from Lactobacillus delbrueckii ssp. bulgaricus OLL1073R-1 prevent influenza virus infection and attenuate secondary bacterial infection risk.

The present study assessed the inhibitory action of exopolysaccharides (EPS) produced by Lactobacillus delbrueckii ssp. bulgaricus OLL1073R-1 against influenza virus infection followed by secondary bacterial infection. We found that the presence of 200 or 400 μg ml of EPS significantly protected against influenza virus infection in a dose-dependent manner when A549 cells were treated with EPS before infection but not after it.

Fosphenytoin Alleviates Herpes Simplex Virus Infection-Induced Provoked and Spontaneous Pain-Like Behaviors in Mice.

In this study, we investigated the effects of fosphenytoin (fPHT), a water-soluble prodrug of phenytoin, on the pain responses of a mouse herpes zoster (HZ) pain model. Transdermal herpes simplex virus type 1 (HSV-1) inoculation induced mechanical allodynia and hyperalgesia of the hind paw and spontaneous pain-like behaviors, such as licking the affected skin. Intravenous injection of fPHT (15 and 30 mg/kg) alleviated HSV-1-induced provoked pain (allodynia and hyperalgesia).

Exogenous ethanol treatment alleviates oxidative damage of under conditions of high-light stress.

Abiotic stresses, such as high light and salinity, are major factors that limit crop productivity and sustainability worldwide. Chemical priming is a promising strategy for improving the abiotic stress tolerance of plants. Recently, we discovered that ethanol enhances high-salinity stress tolerance in and rice by detoxifying reactive oxygen species (ROS).

The Roles of Kidney-Resident ILC2 in Renal Inflammation and Fibrosis.

Innate lymphoid cells (ILCs) are a recently discovered lymphocyte population with high cytokine productive capacity. Type-2 ILCs (ILC2s) are the most studied, and they exert a rapid type-2 immune response to eliminate helminth infections. Massive and sustainable ILC2 activation induces allergic tissue inflammation, so it is important to maintain correct ILC2 activity for immune homeostasis.

Myasthenic crisis appearing after resection of intracardiac ectopic thymoma with superior vena cava syndrome.

Background: We describe herein an extremely rare case of intracardiac ectopic thymoma-only two pure cases have been reported to date-associated with myasthenia gravis, an infrequent complication of ectopic thymoma.

Case Presentation: A 71-year-old woman with superior vena cava syndrome was found to have a large mass mainly located in the right atrium. Tumor resection under cardiopulmonary bypass was performed.

Efficient immunogenic peptide antigen delivery to dendritic cells using an ESCRT-mediated extracellular vesicle formation method.

In the activation of cell-mediated adaptive immune responses that play major roles in the elimination of virus-infected or tumor cells, it is important that dendritic cells present antigen peptides on major histocompatibility complex (MHC) class I molecules and activate pathogen-specific cytotoxic T lymphocytes (CTL). As exogenous peptide antigens are generally presented on MHC class II but not class I, the development of a method for exogenous antigen delivery that facilitates MHC class I presentation is necessary for a potentially effective vaccine that is expected to provoke cell-mediated adaptive immune responses. Here, we developed extracellular vesicles that incorporate antigenic proteins by utilizing endosomal sorting complexes required for transport (ESCRT)-mediated vesicle formation pathway.
