Network meta-analysis enables comprehensive synthesis of evidence concerning multiple treatments and their simultaneous comparisons based on both direct and indirect evidence. A fundamental pre-requisite of network meta-analysis is the consistency of evidence that is obtained from different sources, particularly whether direct and indirect evidence are in accordance with each other or not, and how they may influence the overall estimates. We have developed an efficient method to quantify indirect evidence, as well as a testing procedure to evaluate their inconsistency using Lindsay's composite likelihood method...

Zinc is vastly present in the mammalian brain and controls functions of various cell surface receptors to regulate neurotransmission. A distinctive characteristic of N-methyl-D-aspartate (NMDA) receptors containing a GluN2A subunit is that their ion channel activity is allosterically inhibited by a nano-molar concentration of zinc that binds to an extracellular domain called an amino-terminal domain (ATD). Despite physiological importance, the molecular mechanism underlying the high-affinity zinc inhibition has been incomplete because of the lack of a GluN2A ATD structure...

AIMS: Severe preterm fetal growth restriction (FGR) remote from term is problematic. We aimed to investigate the effect of maternally-administered antithrombin on maternal and neonatal outcomes. A prospective, one-arm, pilot study was performed in 14 women with severe FGR (≤5th centile) at <28 weeks of gestation, without hypertensive disorders. Maternal plasma concentrations of soluble Feline McDonough Sarcoma (FMS)-like trypsin kinase-1 (sFlt-1) and placental growth factor (PlGF) were measured and categorized into three groups: group 1; low sFlt-1 and high PlGF, group 2; moderate sFlt-1 and low PlGF, and group 3; high sFlt-1 and low PlGF...

During cardiac surgery through midline sternotomy, sternum closure metal wires are usually used for. However, metal wires may damage the sternum and cause artifacts on X-ray. Therefore, we use a novel sternum closure technique in which metal wire is replaced by ultra-high molecular weight polyethylene(UHMWP) sutures. We have used this technique for 89 patients in 2014 and reviewed our experience. UHMWPs are often used for bone fracture cerclage, particularly in the vertebral body. UHMWPs may avoid sternal "cheese-cut" dehiscence...

Mitophagy is thought to play an important role in mitochondrial quality control. Mitochondrial division is believed to occur first, and autophagosome formation subsequently occurs to enwrap mitochondria as a process of mitophagy. However, there has not been any temporal analysis of mitochondrial division and autophagosome formation in mitophagy. Therefore, the relationships among these processes remain unclear. We show that the mitochondrial division factor Dnm1 in yeast or Drp1 in mammalian cells is dispensable for mitophagy...

BACKGROUND: Supra/interspinous ligaments connect adjacent spinous processes and act as a stabilizer of the spine. As with other spinal ligaments, it can become ossified. However, few report have discussed ossification supra/interspinous ligaments (OSIL), so its epidemiology remains unknown. We therefore aimed to investigate the prevalence and distribution of OSIL in symptomatic patients with cervical ossification of the posterior longitudinal ligament (OPLL). METHODS: The participants of our study were symptomatic patients with cervical OPLL who were diagnosed by standard radiographs of the cervical spine...

The three-domain phylogenetic system of life has been challenged, particularly with regard to the position of Eukarya. The recent increase of known genome sequences has allowed phylogenetic analyses of all extant organisms using concatenated sequence alignment of universally conserved genes; these data supported the two-domain hypothesis, which place eukaryal species as ingroups of the Domain Archaea. However, the origin of Eukarya is complicated: the closest archaeal species to Eukarya differs in single-gene phylogenetic analyses depending on the genes...

Concentration of both choline plasmalogen (PC-Pls) and ethanolamine Pls (PE-Pls) in human plasma/serum has been getting attention to, since certain patients including those with neurodegenerative disorders, have been reported to exhibit reduced levels of specific Pls species. However, despite using liquid chromatography-tandem mass spectrometry (LC-MS/MS), accurate quantitation of Pls is still difficult because of less product ion from PC-Pls and quantitative issues (e.g., extraction recoveries and matrix effects)...

PURPOSE: Published organ motion data have been collected from measurements of a limited number of points within the organ, the centroid, or the edge of the organ. These are derived from the spatial characteristics of respiratory induced motion; however, this approach does not consider non-rigid organ deformation. We propose a novel quantitative method for evaluating respiratory induced organ motion using Deformable Image Registration (DIR). METHOD: Two phases from a 4-dimensional computed tomography (4D CT) dataset at maximum inspiration and expiration were each taken from five patients...

We assessed long-term outcomes after left main coronary artery (LMCA) stenting based on lesion types and stenting strategies. In the Assessing Optimal percutaneous coronary Intervention for Left Main Coronary Artery stenting registry, we evaluated 1,607 consecutive patients undergoing stent implantation for unprotected LMCA lesions (bifurcation lesions: n = 1318 and nonbifurcation lesions: n = 289). Among the bifurcation lesions, 1,281 lesions were treated with stenting across the bifurcation (bifurcation 1-stent strategy: n = 999 or bifurcation 2-stent strategy: n = 282)...

BACKGROUND: The lipogenic pathway is upregulated in cancer cells, including melanomas. However, the pathological significance of cellular lipids in melanocytic lesions has yet to be determined. In this study, we evaluated intracytoplasmic lipid droplets in melanocytic nevi (MNs) and malignant melanomas via immunohistochemical analysis of adipophilin (ADP), which coats lipid droplets. METHODS: One hundred primary cutaneous melanocytic lesions (33 MNs, 17 melanomas in situ [MIS], and 50 invasive melanomas [IMs]) were immunostained for ADP...

Our bodies possess systems to detect various mechanical stimuli, called mechanosensing. Mechanosensing taking place in the membrane can be classified into to ion channel-dependent one and ion channel-independent one. Ion channel-dependent mechanosensing is a relatively rapid response, involving various mechanosen sensitive channels, including recently identified pannexin. In contrast, ion-channel-independent mechanosensing is a slow response, such as tissue remodeling, and the mechanism via integrin-actin interaction at the focal adhesion is well known...

Microarrays can be a useful tool for pathogen detection as it allow for simultaneous interrogation of the presence of a large number of genetic sequences in a sample. However, conventional microarrays require extensive manual handling and multiple pieces of equipment for printing probes, hybridization, washing and signal detection. In this study, a reverse transcription (RT)-PCR with an accompanying novel automated microarray for simultaneous detection of eight viruses that affect cattle [vesicular stomatitis virus (VSV), bovine viral diarrhoea virus type 1 and type 2, bovine herpesvirus 1, bluetongue virus, malignant catarrhal fever virus, rinderpest virus (RPV) and parapox viruses] is described...

BACKGROUND/OBJECTIVE: Recently, it was confirmed that the daily oral intake of plant sterols of Aloe vera gel (Aloe sterol) significantly increases the skin barrier function, moisture, and elasticity in photoprotected skin. This study aimed to investigate whether Aloe sterol intake affected skin conditions following sunlight exposure in Japanese men. METHODS: We performed a 12-week, randomized, double-blind, placebo-controlled study to evaluate the effects of oral Aloe sterol supplementation on skin conditions in 48 apparently healthy men (age range: 30-59 years; average: 45 years)...

INTRODUCTION: Polymyxin-B immobilised haemoperfusion (PMX-HP) is a promising adjuvant strategy for the treatment of sepsis and septic shock. PMX-HP therapy works by clearing circulating endotoxin through binding to polymyxin-immobilised fibres during haemoperfusion. Small clinical trials have shown that PMX-HP therapy is associated with improved haemodynamic profile, oxygenation and survival. However, clear inferences have been largely inconclusive due to limitations in study design (eg, small, unblinded) and generalisability...

Group I self-splicing intron constitutes an important class of functional RNA molecules that can promote chemical transformation. Although the fundamental mechanism of the auto-excision from its precursor RNA has been established, convenient assay systems for its splicing activity are still useful for a further understanding of its detailed mechanism and of its application. Because some host RNA sequences, to which group I introns inserted form stable three-dimensional (3D) structures, the effects of the 3D structures of exonic elements on the splicing efficiency of group I introns are important but not a fully investigated issue...

Recently, many authors highlighted the potential advantages of a broader prescription of long-acting injectable antipsychotics (LAIs) based on various assumptions, including favorable pharmacokinetic features. In this systematic review, data from randomized controlled trials comparing LAIs versus the oral formulation of the same antipsychotic were meta-analyzed in order to ascertain whether the route of administration may be associated with a different efficacy and tolerability profile. Of 21 included studies, 18 contributed to the meta-analysis, providing data for risperidone, olanzapine, aripiprazole, zuclopenthixol, fluphenazine and haloperidol...

OBJECTIVES: To clarify the prognostic significance of diagnosing whether the failing heart is functioning on the descending limb of the Starling curve by using echocardiography with passive leg lifting (PLL). BACKGROUND: Patients with advanced heart failure can shift to the descending limb of the Starling curve, in which pre-load does not lead to an expected increase in forward left ventricular stroke volume (LVSV). METHODS: Thirty-five consecutive patients with left ventricular (LV) ejection fraction of <40% underwent echocardiography at rest during baseline and during PLL to increase pre-load...

BACKGROUND: The ACC/AHA guidelines introduced a new classification of severe aortic stenosis (AS) mainly based on maximum jet velocity (Vmax) and mean pressure gradient (mPG), but not on aortic valve area (AVA). However, prognostic value of this new classification has not yet been fully evaluated. METHODS AND RESULTS: We studied 1512 patients with asymptomatic severe AS enrolled in the CURRENT AS registry in whom surgery was not initially planned. Patients were divided into 2 groups: Group 1 (N=122) comprised patients who met the recommendation for surgery; high-gradient (HG)-AS (Vmax≥4...
