[CD5-positive diffuse large B-cell lymphoma with gastrointestinal infiltration presenting with protein-losing enteropathy].

Protein-losing enteropathy is rarely associated with malignant lymphoma. This report describes the case of a 67-year-old man with diffuse large B-cell lymphoma (DLBCL) and concomitant protein-losing enteropathy who was admitted to our hospital for evaluation of watery diarrhea, edema, and abdominal fullness. On admission, the patient reported a history of weight gain.

Metabolic state switches between morning and evening in association with circadian clock in people without diabetes.

Aims/introduction: Understanding morning-evening variation in metabolic state is critical for managing metabolic disorders. We aimed to characterize this variation from the viewpoints of insulin secretion and insulin sensitivity, including their relevance to the circadian rhythm.

Materials And Methods: A total of 14 and 10 people without diabetes were enrolled, and underwent a 75-g oral glucose tolerance test (OGTT) and hyperinsulinemic-euglycemic clamp study, respectively.

[Acute thrombocytopenia after obinutuzumab administration in a patient with relapsed follicular lymphoma].

A 64-year-old woman was admitted to our hospital because of relapsed follicular lymphoma. Obinutuzumab (OBZ) and bendamustine (GB) therapy was administered for her lymphoma, and thrombocytopenia requiring platelet transfusion was observed after the first course. Although the dose of bendamustine had been reduced, her thrombocytopenia was observed again after the second course.

Liver-specific dysregulation of clock-controlled output signal impairs energy metabolism in liver and muscle.

The liver is the major organ maintaining metabolic homeostasis in animals during shifts between fed and fasted states. Circadian oscillations in peripheral tissues including the liver are connected with feeding-fasting cycles. We generated transgenic mice with hepatocyte specific E4BP4, D-box negative regulator, overexpression.

Virus-infected peripheral blood plasmablasts in a patient with severe fever with thrombocytopenia syndrome.

Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne viral hemorrhagic disease with a high fatality rate. It is caused by the SFTS virus and is endemic in East Asian countries such as China, South Korea, and Japan. Previous studies have shown that plasmablasts appear transiently in peripheral blood during the acute phase of SFTS, but do not specify the characteristics of these plasmablasts.

Transient Appearance of Plasmablasts in the Peripheral Blood of Japanese Patients With Severe Fever With Thrombocytopenia Syndrome.

Atypical lymphocytes in the peripheral blood in patients with severe fever with thrombocytopenia syndrome (SFTS) have not been well examined. In this study, we analyzed counts and characteristics of atypical lymphocytes in 7 patients with SFTS. Atypical lymphocytes resembled plasma cells morphologically and appeared in the peripheral blood of all patients 4-8 days after onset of disease.

Role of TEM-1 β-Lactamase in the Predominance of Ampicillin-Sulbactam-Nonsusceptible in Japan.

We investigated the epidemiology and resistance mechanisms of ampicillin-sulbactam-nonsusceptible , focusing on the role of the TEM-1 β-lactamase. We collected all nonduplicate clinical isolates at 10 Japanese hospitals during December 2014 and examined their antimicrobial susceptibility, β-lactamases, TEM-1 transferability, TEM-1 β-lactamase activity, outer membrane protein profile, membrane permeability, and clonal genotypes. Among the 329 isolates collected, 95 were ampicillin-sulbactam nonsusceptible.

Clock Gene Dysregulation Induced by Chronic ER Stress Disrupts β-cell Function.

In Wfs1A/a islets, in association with endoplasmic reticulum (ER) stress, D-site-binding protein (Dbp) expression decreased and Nuclear Factor IL-3 (Nfil3)/E4 Promoter-binding protein 4 (E4bp4) expression increased, leading to reduced DBP transcriptional activity. Similar alterations were observed with chemically-induced ER stress. Transgenic mice expressing E4BP4 under the control of the mouse insulin I gene promoter (MIP), in which E4BP4 in β-cells is expected to compete with DBP for D-box, displayed remarkable glucose intolerance with severely impaired insulin secretion.

Comparison of Geriatric Nutritional Risk Index scores on physical performance among elderly patients with chronic obstructive pulmonary disease.

Objectives: The Geriatric Nutritional Risk Index (GNRI) is a new prognostic indicator for nutritional status-related complications and mortality among the elderly. Here we aimed to compare 6-min walk distance (6MWD) between high and low GNRI groups for patients with COPD.

Methods: We enrolled 63 elderly men with COPD.

Long-term Effect of Home Nursing Intervention on Cost and Healthcare Utilization for Patients with Chronic Obstructive Pulmonary Disease: A Retrospective Observational Study.

Purpose: The present study aimed to examine the long-term effects of a home nursing intervention on healthcare utilization and costs among patients with chronic obstructive pulmonary disease (COPD).

Design: A 3-year retrospective study.

Methods: Eleven COPD patients who had received home nursing intervention after hospital discharge were enrolled.

Safety and efficacy of peramivir for influenza treatment.

Objective: This report presents a review of the efficacy and safety of peramivir, a neuraminidase inhibitor that was granted Emergency Use Authorization by the US Food and Drug Administration (FDA) from October 23, 2009 to June 23, 2010 during the 2009 H1N1 pandemic.

Methods: Literature was accessed via PubMed (January 2000-April 2014) using several search terms: peramivir; BCX-1812; RWJ 270201; H1N1, influenza; antivirals; and neuraminidase inhibitors. The peramivir manufacturers, Shionogi and Co Ltd and BioCryst Pharmaceuticals, were contacted to obtain unpublished data and information presented at recent scientific meetings.

[Risk factors for the onset of aspiration pneumonia among stroke patients in the recovery stage].

Aim: Post-stroke aspiration pneumonia is one of the most common complications among stroke patients. Although the onset of aspiration pneumonia is caused by a disruption of the balance between invasion (the type and amount of oral flora and aspiration) and host resistance (the protective airway reflex and immune function), several previous studies have focused on invasion, such as aspiration and dysphagia. In this study, we examined the importance of the host resistance to aspiration pneumonia among stroke patients with dysphagia.

Quantitative trait locus that determines the cross-sectional shape of the femur in SAMP6 and SAMP2 mice.

Unlabelled: We segregated a QTL on chromosome 11 that affects femoral cross-sectional shape during growth by generating a congenic strain and an additional 16 subcongenic strains of the senescence-accelerated mouse strain, SAMP6. The QTL region was narrowed down to a 10.0-Mbp region.

Consistency of low bone density across bone sites in SAMP6 laboratory mice.

The development of bone densitometry has made it clear that there are discrepancies in bone density at various measurement sites in a given individual. This study examined the consistency of bone density measurements across various sites in a strain of laboratory mouse (senescence-accelerated mouse; SAM). A systemic evaluation of the bone density was performed by dual-energy X-ray absorptiometry (DXA) on SAMP6 (P6) mice, a strain with low peak bone density, as measured by microphotodensitometry of the femoral bones, whereas the SAMP2 (P2) and SAMR1 (R1) strains have high peak bone density.

A congenic mouse and candidate gene at the Chromosome 13 locus regulating bone density.

Previously, we identified two significant quantitative trait loci (QTLs) specifying the peak relative bone mass (bone mass corrected for bone size) on chromosomes (Chrs) 11 and 13 by interval mapping in two mouse strains, SAMP2 and SAMP6. The latter strain is an established murine model of senile osteoporosis and exhibits a significantly lower peak relative bone mass than SAMP2 mice. We recently designated the Chr 13 locus as Pbd2 (Peak bone density 2) and constructed a congenic strain, P6.

The aniracetam metabolite 2-pyrrolidinone induces a long-term enhancement in AMPA receptor responses via a CaMKII pathway.

The present study was conducted to assess the effect of aniracetam and its metabolites, such as 2-pyrrolidinone, p-anisic acid, and anisamide butyrate, on the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, heteromerically formed of GluR1,2 (GluR1 and GluR2), GluR1,3 (GluR1 and GluR3), and GluR1,2,3 (GluR1, GluR2, and GluR3), expressed in Xenopus oocytes. 2-Pyrrolidinone potentiated kainate-evoked currents through GluR1,2,3 channels in a bell-shaped dose-dependent manner at concentrations ranged from 1 nM to 300 microM, with a maximal effect at 100 microM. The potentiation was long-lasting, reaching approximately 180% of basal levels 60 min after 5-min treatment with 2-pyrrolidinone at 100 microM.
