The deposition and dissolution of sodium superoxide (NaO2 ) was investigated by atomic force microscopy. Rectangular prisms consisting of 8 smaller sub-structures grew from NaO2 platelets, when discharged in 0.5 M NaClO4 , diethylene glycol dimethyl ether on highly ordered pyrolytic graphite. During oxidation the 8 sub-structures are conserved. Ring-like structures of Na2 CO3 of 200 nm diameter remain at the end of oxidation.

Approximately 5-10% of individuals, who are vaccinated with a hepatitis B (HB) vaccine designed based on the HBV genotype C, fail to acquire protective levels of antibodies. Here, host genetic factors behind low immune response to this HB vaccine were investigated by a genome wide association study (GWAS) and HLA association tests. A GWAS and HLA association tests were carried out using a total of 1,193 Japanese individuals including 107 low responders, 351 intermediate responders, and 735 high responders. Classical HLA class II alleles were statistically imputed using the genome-wide SNP typing data...

This paper reports on the influence that extreme values in the tails of the North Atlantic Oscillation (NAO) Index probability density function (PDF) can exert on temperatures in Europe. When the NAO Index enters into its lowest (10% quantile or less) and highest (90% quantile or higher) modes, European temperatures often exhibit large negative or positive departures from their mean values, respectively. Analyses of the joint quantiles of the Index and temperatures (i.e., the simultaneous exceedance of particular quantile thresholds by the two variables) show that temperatures enter into the upper or lower tails of their PDF when the NAO Index also enters into its extreme tails, more often that could be expected from random statistics...

OBJECTIVE: Globus sensation, a feeling of lump or something stuck in the throat, could be caused by structural, functional, and psychogenic diseases. Due to a possible multifactorial nature of the disease, neither diagnosing test battery nor standard treatment for globus sensation has been established. Therefore, a questionnaire to accurately identify globus patients and evaluate the severity of the disease is desired. Glasgow Edinburgh Throat Scale (GETS) is a 10-item questionnaire about the throat symptoms consisting of three subscales relating to dysphagia, globus sensation, and pain/swelling in the throat...

The family Ascoviridae is a recently described virus family whose members are transmitted by parasitoids and cause chronic and lethal infections in lepidopteran insects. Little is known about the biology and ecology of ascoviruses, and few isolates have been found outside the United States. We report here the isolation of a new ascovirus variant from Spodoptera litura in Japan. Full genome sequence and phylogenetic analyses showed that this virus was closely related to variants in Heliothis virescens ascovirus-3a, and it was named HvAV-3j...

Immigrant women face unique barriers to prenatal care access and patient-provider communication. Yet, few prior studies have examined U.S.-born/immigrant differences in the content of care. The purpose of this study was to investigate the roles of immigrant status, English proficiency and race/ethnicity on the receipt of self-reported prenatal counseling using nationally representative data. We used data from the Early Childhood Longitudinal Study-Birth Cohort (N ≈ 8100). We investigated differences in self-reported prenatal counseling by immigrant status, English proficiency, and race/ethnicity using logistic regression...

PURPOSE: Fluorouracil monotherapy, instead of the FOLFOX or FOLFIRI regimen, is administered to patients intolerant to oxaliplatin or irinotecan because of their adverse effects. A prospective clinical trial was designed to evaluate the efficacy and safety of fluorouracil monotherapy combined with panitumumab administered to patients with KRAS wild-type (WT) metastatic colorectal cancer (mCRC) intolerant to oxaliplatin and irinotecan. Screening for potential serum biomarkers to predict early therapeutic responses was conducted...

Tendon is a dense connective tissue that transmits high mechanical forces from skeletal muscle to bone. The transcription factor scleraxis (Scx) is a highly specific marker of both precursor and mature tendon cells (tenocytes). Mice lacking scx exhibit a specific and virtually complete loss of tendons during development. However, the functional contribution of Scx to wound healing in adult tendon has not yet been fully characterized. Here, using ScxGFP-tracking and loss-of-function systems, we show in an adult mouse model of Achilles tendon injury that paratenon cells, representing a stem cell antigen-1 (Sca-1)-positive and Scx-negative progenitor subpopulation, display Scx induction, migrate to the wound site, and produce extracellular matrix (ECM) to bridge the defect, whereas resident tenocytes exhibit a delayed response...

Rather than being homogenous diffusion-dominated structures, biological membranes can exhibit areas with distinct composition and characteristics, commonly termed as lipid domains. Arguably the most comprehensively studied examples in bacteria are domains formed by cardiolipin, which have been functionally linked to protein targeting, the cell division process and the mode of action of membrane-targeting antimicrobials. Cardiolipin domains were originally identified in the Gram-negative model organism Escherichia coli based on preferential staining by the fluorescent membrane dye nonylacridine orange (NAO), and later reported to also exist in other Gram-negative and -positive bacteria...

PURPOSE: For unresectable locally advanced (UR-LA) pancreatic cancer, chemoradiotherapy has been recommended by the NCCN guidelines. We designed a chemoradiotherapy protocol using nab-paclitaxel combined with gemcitabine (GnP) for patients with UR-LA pancreatic cancer. The purpose of this phase I study was to determine a recommended dose (RD) for this novel regimen. METHODS: Patients with UR-LA pancreatic cancer were eligible. The frequency of dose-limiting toxicities (DLTs) was evaluated, and the RD was determined...

HER2 overexpression accounts for approximately 15%-20% of all breast cancers. We have shown that HER2 overexpression leads to elevated expression of the aryl hydrocarbon receptor (AhR) in breast cancer cells. In this study, firstly, we showed that AhR expression was up-regulated by treatment with the HER3 ligand heregulin (HRG) in HER2-overexpressing breast cancer cell lines. Induction of AhR was mediated by transcriptional activation of the region of AhR promoter corresponding to -190 to -100bp. In addition, HRG treatment elicited nuclear translocation of AhR...

Recent increases in ivory poaching have depressed African elephant populations. Successful enforcement has led to ivory being stockpiled. Stockpile destruction is becoming increasingly popular, and most destruction has occurred in the last five years. Ivory destruction is intended to send a strong message against ivory consumption, both in promoting a taboo on ivory use and catalyzing policy change. However, there has been no effort to establish the distribution and extent of media reporting on ivory destruction events globally...

Riassunto. Il presente studio intende confrontare il rischio di non persistenza e l'utilizzo delle risorse sanitarie nei pazienti con fibrillazione atriale non valvolare (FANV) naïve al trattamento con antagonisti della vitamina K (AVK) o con nuovi anticoagulanti orali (NAO). Partendo dai database amministrativi di cinque ASL italiane, sono stati selezionati e inclusi nello studio tutti i pazienti con almeno una dimissione ospedaliera per FANV dal 2011 al 2014. Tra questi, i nuovi utilizzatori di AVK o NAO nel 2014 sono stati identificati e seguiti a partire dalla data della prima prescrizione al verificarsi di uno qualsiasi dei seguenti eventi: interruzione della terapia superiore a 90 giorni, passaggio o aggiunta di una molecola differente rispetto a quella prescritta alla data indice, morte del paziente, fine del follow-up (dicembre 2015)...

Casein is the major milk protein to nourish infants but, in certain population, it causes cow's milk allergy, indicating the uptake of antigenic casein and their peptides through the intestinal epithelium. Using human intestinal Caco-2 cell monolayers, the apical-to-basal transepithelial transport of casein was investigated. Confocal microscopy using component-specific antibodies showed that αs1-casein antigens became detectable as punctate signals at the apical-side cytoplasm and reached to the cytoplasm at a tight-junction level within a few hours...

Porphyromonas gingivalis produces hydrogen sulfide (H2S) from l-cysteine. However, the role of H2S produced by P. gingivalis in periodontal inflammation is unclear. In this study, we identified the enzyme that catalyses H2S production from l-cysteine and analysed the role of H2S using a mouse abscess model. The enzyme identified was identical to methionine γ-lyase (PG0343), which produces methyl mercaptan (CH3SH) from l-methionine. Therefore, we analysed H2S and CH3SH production by P. gingivalis W83 and a PG0343-deletion mutant (ΔPG0343) with/without l-cysteine and/or l-methionine...

Staphylococcus aureus bi-component pore-forming toxins consist of S- and F-components, and form hetero-octameric beta-barrel pores on target blood cell membranes. Among them, γ-hemolysin (Hlg2 and LukF) and LukED (LukE and LukD) possess hemolytic activity, whereas the Panton -Valentine leukocidin (LukS-PV and LukF-PV) does not lyse human erythrocytes.Here, we focused on four loop structures in the rim domain of S-component, namely loops -1, -2, -3, and -4, and found that replacement of loop-4 in both Hlg2 and LukE with that of LukS-PV abolished their hemolytic activity...

Enclosing functional nanoparticles in stable inorganic supports is important for generating ultra-stable catalytic active sites with good performance and material utilization efficiency. Here we describe a simple method to synthesize ultra-thin Ag nanocrystals with dimensions that are defined by the ∼1.4 nm 2D interlayer separating a layered silicate nanostructure. We call the particles "nanoplates" because they are <1.4 nm thick in one direction and their in-plane dimensions are defined by reaction time...

INTRODUCTION: Laparoscopic surgery is less invasive than open surgery and is now common in various medical fields. However, laparoscopic surgery is more difficult than open surgery and often requires additional time for the operator to achieve mastery. Therefore, we investigated the use of assistive technology for uniform laparoscopic surgery. METHODS: We used the OpenCV2 library for augmented reality with an ArUco marker to detect and estimate forceps positioning...

The risk of infective endocarditis in chronic hemodialysis patients is markedly higher than that in the general population. We report the first case of a hemodialysis patient with infective endocarditis caused by Streptococcus dysgalactiae subsp. equisimilis (SDSE) who presented with streptococcal toxic shock syndrome. In the last decade, there has been an increase in the incidence of SDSE infections. Therefore, it is important to recognize SDSE as a possible causative agent of infective endocarditis in an immunocompromised population, such as hemodialysis patients...
