Anticyclic citrullinated protein antibody (ACPA) is known as an important indicator for diagnosis of rheumatoid arthritis (RA). Our aim was to examine the relationship between the serum ACPA titer at baseline and responsiveness to biological agents (antagonists of either tumor necrosis factor or interleukin 6) in patients with RA. ACPA was measured using(More)
OBJECTIVE It has become clear through epidemiological analysis that the incidence of cancers of the lung, liver, colon, and rectum are increasing in Japan every year. However, there have been few epidemiological analyses of nasopharyngeal carcinoma (NPC) in Japan. The aim of this study was to analyze the epidemiology and current incidence of NPC in the(More)
Seasonal allergic rhinitis (SAR) to the Japanese cedar, Cryptomeria japonica (JC) pollen is an IgE-mediated type I allergy affecting nasal mucosa. However, the molecular events underlying its development remain unclear. We sought to identify SAR-associated altered gene expression in nasal epithelial cells during natural exposure to JC pollen. We recruited(More)
Mast cells (MC) play an important role in allergic and non-allergic immune responses. Activation of human MC is modulated by several cell surface inhibitory receptors, including recently identified Allergin-1 expressed on both human and mouse MC. Although Allergin-1 suppresses IgE-mediated, mast cell-dependent anaphylaxis in mice, the expression profile and(More)
Most of the previously reported loci for total immunoglobulin E (IgE) levels are related to Th2 cell-dependent pathways. We undertook a genome-wide association study (GWAS) to identify genetic loci responsible for IgE regulation. A total of 479,940 single nucleotide polymorphisms (SNPs) were tested for association with total serum IgE levels in 1180(More)
BACKGROUND Allergic diseases are an important health problem for children and adults. It is important to know how allergic diseases develop and remit from infancy to adolescence. Early intervention is effective in treating allergic diseases. OBJECTIVE We performed a large-scale questionnaire survey of high school students in Fukui Prefecture, Japan, and(More)
Cysteinyl leukotriene and leukotriene receptor occupancy have been linked to several processes in seasonal allergic rhinitis (SAR), including nasal congestion, rhinorrhea, and recruitment of inflammatory cells. We investigated whether add-on loratadine, an antihistamine, might be effective for SAR patients showing unsatisfactory control of symptoms with the(More)
Continuous positive airway pressure (CPAP) is effective for patients with SAS. CPAP therapy requires long-term usage to prevent recurrence of symptoms. It is, thus, important to examine the level of long-term CPAP use and the factors influencing compliance with CPAP therapy for SAS. Compliance with CPAP therapy was examined in 204 patients in whom such(More)
During early 2000, a new analytical procedure for nitrate isotopic measurement, termed the "denitrifier method", was established. With the development of the nitrate isotope tracer method, much research has been reported detailing sources of groundwater nitrate and denitrification mechanisms. However, a shortcoming of these tracer studies has been indicated(More)
The traditional paradigm of eosinophils as end-stage damaging cells has mainly relied on their release of cytotoxic proteins. Cytokine-induced cell survival and secretion of granular contents from tissue-dwelling eosinophil are thought to be important mechanisms for eosinophilic inflammatory disorders, although the occurrence of cytolysis and its products(More)
