Diabetes mellitus, a multifactorial disorder, is related to the intestinal microbiota via numerous molecular mechanisms. The vast increase in the prevalence of diabetes and its associated complications requires a natural and safe solution. There is a growing evidence of gut microbiota effi ciency in improving insulin resistance, impaired insulin secretion, and metabolic complications in diabetic patients. Probiotics are defi ned as live microorganisms that, when ingested in adequate amounts, exert health benefi ts to the host...

Epidemiological studies have demonstrated an association between low serum albumin levels and both coronary artery disease (CAD) and mortality. However, the long-term clinical impact of low serum albumin level in patients with CAD undergoing percutaneous coronary intervention (PCI) has not yet been fully investigated. We studied 2860 all-comer patients with CAD who underwent their first PCI and had data available for pre-procedural serum albumin between 2000 and 2011. Patients were assigned to tertiles based on pre-procedural albumin levels...

A 30-year-old Japanese man was diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH) with lupus anticoagulants (LAs) in 2003. He underwent pulmonary endarterectomy after the placement of an inferior vena cava filter (IVCF) in 2004, and treatment with warfarin was continued. In 2014, IVCF occlusion and marked collateral circulation were noted during an examination for transient dyspnea; however, his warfarin level was within the therapeutic range for 88.9% of the time from 2003 to 2014. We herein report a rare case of CTEPH and LAs with IVCF occlusion; in such cases, intense treatment may be required...

The expression of transgenes introduced into a plant genome is sometimes suppressed by RNA silencing. Although local and systemic spread of RNA silencing have been studied, little is known about the mechanisms underlying spatial and temporal variation in transgene silencing between individual plants or between plants of different generations, which occurs seemingly stochastically. Here, we analyzed the occurrence, spread, and transmission of RNA silencing of the green fluorescent protein (GFP) gene over multiple generations of the progeny of a single soybean transformant...

Print-specific N170 in event-related potentials is generally considered to reflect relatively automatic processing for letter strings, which is crucial for fluent reading. However, our previous studies demonstrated that print-specific N170 for transparent Japanese Hiragana script consists of at least two subcomponents under rapid stimulus presentation: an attention-related left-lateralized N170 and a bilateral N170 associated with more automatic orthographic processes (Okumura, Kasai & Murohashi, 2014, 2015)...

OBJECTIVE: To investigate the relationship between renal function and linezolid (LZD)-induced thrombocytopenia and elucidate the underlying mechanism using a chronic renal disease (CRD) mouse model. MATERIALS AND METHODS: CRD was induced in 5-week-old male Institute of Cancer Research (ICR) mice by 5/6 nephrectomy. After this procedure, LZD (25 and 100 mg/kg) was administered intraperitoneally once every day for 28 days. Platelet counts, white blood cell (WBC) counts, and hematocrit (HCT) levels were measured every 7 days...

Intravenous immunoglobulin (IVIg) has been a candidate as a potential anti-amyloid immunotherapy for Alzheimer disease (AD) because it contains anti-amyloid β (Aβ) antibodies. Although several studies with IVIg in AD have been published, changing levels of Aβ efflux from the brain, or disaggregation of Aβ species induced by immunotherapy, have not been properly investigated. Here, we carried out an open label study of therapy with IVIg in five patients with AD. We collected plasma from a peripheral vein (peripheral-plasma) and from the internal jugular vein (jugular-plasma) to estimate directly the efflux of soluble Aβ from the brain...

The bacterial flagellar motor is a reversible rotary nano-machine powered by the ion flux across the cytoplasmic membrane. Each motor rotates a long helical filament that extends from the cell body at several hundreds revolutions per second. The output of the motor is characterized by its generated torque and rotational speed. The torque can be calculated as the rotational frictional drag coefficient multiplied by the angular velocity. Varieties of methods, including a bead assay, have been developed to measure the flagellar rotation rate under various load conditions on the motor...

Malnutrition has been identified as an important predictor of poor clinical outcomes in patients with heart failure. The aim of this study is to examine the prognostic impact of nutritional status in patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI). The impact of nutrition, assessed using the geriatric nutritional risk index (GNRI) calculated by serum albumin and body mass index, was evaluated in 2,853 patients with CAD who underwent their first PCI between 2000 and 2011...

Leiomyomatoid angiomatous neuroendocrine tumour (LANT) is possibly a new disease entity that was reported as a dimorphic neurosecretory tumour with a leiomyomatous vascular component; it was found in the pituitary. We describe uterine LANT-like malignant tumour in a 45-year-old woman with uterine mesenchymal tumour, diagnosed clinically as uterine leiomyoma. She underwent laparoscopic myomectomy. The tumour consisted of hyalinized vasculature, containing factor VIII-positive endothelium and α-smooth muscle actin-positive vascular smooth muscle cells, and stromal cells, expressing neuroadhesion molecules...

INTRODUCTION: Both types of sleep-disordered breathing (SDB), obstructive and central sleep apnoea (OSA and CSA, respectively), are common in patients with heart failure and reduced ejection fraction (HFrEF). In such patients, SDB is associated with increased cardiovascular morbidity and mortality but it remains uncertain whether treating SDB by adaptive servo-ventilation (ASV) in such patients reduces morbidity and mortality. AIM: ADVENT-HF is designed to assess the effects of treating SDB with ASV on morbidity and mortality in patients with HFrEF...

P21-activated kinases (PAKs) are important regulators of cell motility and morphology. It has been challenging to interrogate their functions because cells adapt to genetic manipulation of PAK, and because inhibitors act on multiple PAK isoforms. Here we describe genetically encoded PAK1 analogues that can be selectively activated by the membrane-permeable small molecule rapamycin. An engineered domain inserted away from the active site responds to rapamycin to allosterically control activity of the PAK1 isoform...

HLA-G is a natural tolerogenic molecule and has the following unique features: seven isoforms (HLA-G1 to HLA-G7), formation of disulfide-linked homodimers, and β2-microglobulin (β2m)-free forms. Interestingly, individuals null for the major isoform, HLA-G1, are healthy and expressed the α2 domain-deleted isoform, HLA-G2, which presumably compensates for HLA-G1 function. However, the molecular characteristics of HLA-G2 are largely unknown. In this study, we unexpectedly found that HLA-G2 naturally forms a β2m-free and nondisulfide-linked homodimer, which is in contrast to the disulfide-bonded β2m-associated HLA-G1 homodimer...

BACKGROUND: Recent rodent and human studies provide evidence in support of the fact that CD157, well known as bone marrow stromal cell antigen-1 (BST-1) and a risk factor in Parkinson's disease, also meaningfully acts in the brain as a neuroregulator and affects social behaviors. It has been shown that social behaviors are impaired in CD157 knockout mice without severe motor dysfunction and that CD157/BST1 gene single nucleotide polymorphisms are associated with autism spectrum disorder in humans...
