DNAM-1 (CD226) is an activating immunoreceptor expressed on lymphocytes and myeloid cells. CD155 and CD112 are the ligands for DNAM-1. DNAM-1 plays an important role in tumor immunity mediated by CD8(+) T cells and NK cells. Moreover, the interaction of DNAM-1 with the ligands contributed to the development of acute graft versus host disease (GVHD) and treatment with anti-DNAM-1 monoclonal antibodies (mAb) dramatically improved acute GVHD in a mouse model, suggesting that DNAM-1 may be a good molecular target for therapy to acute GVHD in human...

Panitumumab is a monoclonal antibody developed against the human epidermal growth factor receptor (EGFR). TAS-102 is a novel chemotherapeutic agent containing trifluridine (FTD) as the active cytotoxic component. Both panitumumab and TAS-102 have been approved for the treatment of metastatic colorectal cancer. In this study, we revealed the mechanism underlying the anticancer effects of panitumumab/TAS-102 combination using preclinical models. Panitumumab/FTD co-treatment showed additive antiproliferative effects in LIM1215 and synergistic antiproliferative effects in SW48 colon cancer cells...

We evaluated a cohort of patients treated with alcohol septal ablation (ASA) to identify predictive factors for repeat ASA. We compared 15 patients who underwent repeat ASA procedures (group R) with 69 patients not requiring repeat procedures (group S) in terms of clinical parameters and morphologic cardiac magnetic resonance. Group R showed higher number of hypertrophic segments (thickness ≥15 mm) in the basal left ventricular level (2.8 ± 1.7 vs 1.7 ± 0.8, p = 0.009) than group S. In the multivariate analysis, diuretics use (adjusted odds ratio 5...

In the late 19th century, Charcot examined patients with amyotrophic lateral sclerosis (ALS) and concluded that the sclerosis in the lateral columns of the spinal cord induced the loss of neurons in the anterior horns. The reason for this remains unknown. In contrast, hyperexcitability of motor neurons is believed to be one of the pathogenetic factors for motor neuron death in ALS. In this article, I have reviewed the relationship between motor neuron hyperexcitability and motor neuron death and considered the mechanism of ALS pathogenesis...

In addition to plaque rupture (PR), calcified nodule (CN) may also have the potential to develop into arterial thrombus in the peripheral arteries. This study evaluated the distribution of plaque ruptures and calcified nodules in the peripheral arteries and their impact on the outcome of endovascular therapy (EVT). Consecutive 159 patients who underwent EVT with intravascular ultrasound guidance were enrolled. The position of CNs and PRs were assigned to any of common iliac artery, external iliac artery, common femoral artery, and superficial femoral artery...

Psoriasis is a multifactorial inflammatory disorder, in which the inflammation affects not only the skin but also the other internal organs, and can induce cardiovascular and cerebrovascular involvements. However, few predictive factors of cardiovascular diseases have been clarified in patients with psoriasis. This study was performed to verify whether diagonal earlobe creases (ELC) can reflect the hidden comorbidities in Japanese psoriatic patients. Prevalence and subtypes of ELC were analyzed in patients with psoriatic and with non-psoriatic skin diseases, and the correlation with coronary artery calcification (CAC) or fatty liver (FL) detected by computed tomography...

Root amputation, extraction of a single tooth, bone loss or severe tooth mobility, and an unclosed wound were significantly associated with increased risk of developing medication-related osteonecrosis of the jaw (MRONJ). We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. INTRODUCTION: Osteonecrosis of the jaws can occur following tooth extraction in patients receiving bisphosphonate drugs...

Genome-wide scans for positive selection have become important for genomic medicine, and many studies aim to find genomic regions affected by positive selection that are associated with risk allele variations among populations. Most such studies are designed to detect recent positive selection. However, we hypothesize that ancient positive selection is also important for adaptation to pathogens, and has affected current immune-mediated common diseases. Based on this hypothesis, we developed a novel linkage disequilibrium-based pipeline, which aims to detect regions associated with ancient positive selection across populations from single nucleotide polymorphism (SNP) data...

As Japan has achieved one of the lowest perinatal mortality rates (PMR), our study aims to estimate trends in and risk factors for perinatal mortality among singleton births in Japan. We used Japanese vital registration data to assess trends in and risk factors for perinatal outcomes between 1979 and 2010. Birth and death registration data were merged. An autoregressive integrated moving average model was fitted separately by sex to the PMR and the proportion of stillbirths. A multilevel Poisson regression model was used to estimate risk factors for perinatal mortality...

Dysregulation of the complement system is linked to the pathogenesis of a variety of hematological disorders. Eculizumab, an anti-complement C5 monoclonal antibody, is the current standard of care for paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). However, because of high levels of C5 in plasma, eculizumab has to be administered biweekly by intravenous infusion. By applying recycling technology through pH-dependent binding to C5, we generated a novel humanized antibody against C5, SKY59, which has long-lasting neutralization of C5...

Mast cells (MCs) play pivotal roles in allergic reactions and the host defense against microbial infection through the immunoglobulin E (IgE)-dependent and IgE-independent signaling pathways. MC lines that can be analyzed both in vitro and in vivo would be useful for the study of MC-dependent immune responses. Here we investigated the functional characteristics of a mouse ES cell-derived mast cell-like cell line, MEDMC-BRC6. The cell line expressed FcεRI and c-Kit and showed degranulation and production of inflammatory cytokines and chemokine, including TNF-α, IL-6 and MCP-1, upon crosslinking FcεRI with IgE...

This report describes two patients with sporadic lymphangioleiomyomatosis complicated by protein-losing enteropathy (PLE). Imaging studies indicated retroperitoneal lymphangioleiomyomas and abnormalities of the adjacent digestive tract. Endoscopic mucosal biopsy revealed colonic lymphangiectasia in one patient; whereas the site in the other patient was intestinal. Treatment with sirolimus led to the complete resolution of PLE within several months; additionally, marked shrinkage was observed in the lymphangioleiomyomas of both cases...

In the presence of a cationic Ru catalyst, 1,6-diynes bearing a terminal styryl moiety underwent [2+2+2] cyclization to produce dehydrobiphenylenes fused with a five-membered ring. Although the cycloadducts were unstable toward purification, their one-pot iodine-mediated ring expansion successfully afforded unprecedented bridged ketone products containing a benzo-fused bicyclo[3.2.1] framework.

Behçet's disease (BD) is reportedly associated with polymorphisms of the ubiquitin-associated domain containing 2 (UBAC2) gene in Turkish, Italian, and Chinese populations. Here we investigated whether UBAC2 polymorphisms were associated with BD in a Japanese population. Using data from 611 Japanese BD patients and 737 Japanese controls who participated in our previous genome-wide association study, we analyzed the 58 genotyped single-nucleotide polymorphisms (SNPs) in the region 100 kb upstream and downstream of UBAC2...

A membrane process combining nanofiltraion (NF) and forward osmosis (FO) was developed for the sugar concentration with the aim of high bio-ethanol production from the liquid fraction of rice straw. The commercial NF membrane, ESNA3, was more adequate for removal of fermentation inhibitors (such as acetic acid) than the FO membrane, whereas the commercial FO membrane, TFC-ES, was more adequate for concentration of the sugars than the NF membrane. The liquid fraction was subjected to the following process: NF concentration with water addition (NF(+H2O))→enzymatic hydrolysis→FO concentration...
