The clinical and genetic relationships between Alzheimer's disease (AD) and glaucoma remain obscure. The aim of this study was to determine the prevalence of open-angle glaucoma (OAG) in patients with AD and whether the apolipoprotein E (APOE) 4 allele is associated with AD, with or without OAG, in Japanese. The groups consisted of 172 patients with the(More)
The recent outbreak of malformations in ruminants in Northern Europe caused by Schmallenberg virus induced us to analyze the genetic properties of the related orthobunyaviruses and clarify their relationship. The sequencing of three genomic RNA segments of Sathuperi, Shamonda and Douglas viruses (SATV, SHAV and DOUV) revealed that the M RNA segment of SATV(More)
The G gene encoding the neutralization antigen of bovine ephemeral fever virus (BEFV) was characterized in order to define the virus's molecular epidemiology in Japan and the genetic relationships among the Japanese, Taiwanese and Australian isolates. The nucleotide and amino acid sequences of the gene were highly conserved among the Japanese strains,(More)
BACKGROUND Akabane virus is a member of the genus Orthobunyavirus in the family Bunyaviridae. It is transmitted by hematophagous arthropod vectors such as Culicoides biting midges and is widely distributed in temperate to tropical regions of the world. The virus is well known as a teratogenic pathogen which causes abortions, stillbirths, premature births(More)
BACKGROUND Continuous-flow left ventricular assist devices (LVAD) are increasingly used for patients with end-stage heart failure (HF). We analyzed the effects of ventricular decompression by continuous-flow versus pulsatile-flow LVADs on myocardial structure and function in this population. METHODS AND RESULTS Sixty-one patients who underwent LVAD(More)
OBJECTIVE Non-invasive diagnosis of rejection is a major objective in the management of heart transplant recipients. The ability of strain rate (SR) imaging on echocardiograms to detect rejection in heart transplant recipients was investigated. METHODS A total of 396 endomyocardial biopsies, right-heart catheterisation and echocardiograms were performed(More)
BACKGROUND Liver dysfunction increases post-surgical morbidity and mortality. The Model of End-stage Liver Disease (MELD) estimates liver function but can be inaccurate in patients receiving oral anti-coagulation. We evaluated the effect of liver dysfunction on outcomes after ventricular assist device (VAD) implantation and the dynamic changes in liver(More)
Mycobacterium avium subsp. hominissuis (MAH) strains are genetically diverse and cause infections in pigs and humans. To elucidate the geographical and host-dependent variations in the genetic diversity of MAH, we performed variable numbers of tandem repeat (VNTR) analysis targeting 19 loci for MAH samples from humans (n=146), bathroom environments (n=37),(More)
In September 2012, several cows and a calf showed decreased activity, anorexia and fever on Ishigaki Island, Okinawa Prefecture, Japan, and the cases were diagnosed as bovine ephemeral fever (BEF). We isolated BEF virus (BEFV) from one of the affected cows and then determined the complete genome sequence of the G gene, which encodes a class I transmembrane(More)
Vascular inflammation plays an important role in the development of myocardial infarction (MI). Lymphotoxin α (LTA) is a cytokine with multiple functions in regulation of the immune system and inflammatory reactions. The aim of this study was to examine whether polymorphisms of the LTA gene are associated with the risk of MI in Japanese men and women. A(More)
