Moraxella catarrhalis is a significant cause of respiratory tract infection against which a vaccine is sought. Several outer membrane proteins are currently under investigation as potential vaccine antigens, including the porin M35. We have previously shown that the third external loop of M35 was immunodominant over the remainder of the protein for antibody produced in mice against the refolded...

OBJECTIVES The outer membrane protein M35 of Moraxella catarrhalis is an antigenically conserved porin. Knocking out M35 significantly increases the MICs of aminopenicillins. The aim of this study was to determine the biological mechanism of this potentially new antimicrobial resistance mechanism of M. catarrhalis and the behaviour of M35 in general stress situations. METHODS PCR using m35-sp...

Moraxella catarrhalis is a gram-negative respiratory pathogen that is an important causative agent for otitis media and exacerbations of chronic obstructive pulmonary disease. We have previously predicted the outer membrane protein M35 to be a general porin, and in the current study, we have investigated the function of M35 and its importance for survival of M. catarrhalis in vivo. Lipid bilaye...

Elucidating the structure of Aβ(1-40) fibrils is of interest in Alzheimer's disease research because it is required for designing therapeutics that target Aβ(1-40) fibril formation at an early stage of the disease. M35 is a crucial residue because of its potential oxidation and its strong interactions across β-strands and across β-sheets in Aβ fibrils. Experimentally, data for the three-fold sy...

The type I interferon (IFN) response is imperative for the establishment of the early antiviral immune response. Here we report the identification of the first type I IFN antagonist encoded by murine cytomegalovirus (MCMV) that shuts down signaling following pattern recognition receptor (PRR) sensing. Screening of an MCMV open reading frame (ORF) library identified M35 as a novel and strong neg...

AIMS Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are conjugated ethanol metabolites formed in low amounts after alcohol consumption. Compared with ethanol, EtG and EtS are excreted in urine for a prolonged time, making them useful as sensitive alcohol biomarkers. This study determined the detection times for EtG and EtS in alcoholic patients undergoing alcohol detoxification. METHODS Alco...

The aim of this study is to investigate the concentrations of ethyl glucuronide (EtG) in oral fluid and both EtG and ethyl sulfate (EtS) in blood and urine following intense use of mouthwash and ingestion of nonalcoholic wine, which are proven to contain 3 mg/L EtG, 1.5 mg/L EtS, and 0.2 g/L ethanol. Twelve subjects participated in a controlled experiment. All subjects ingesting nonalcoholic wi...

AIMS In heavy alcohol consumption laboratory tests represent an objective evidence. In this study we compared older and newer biomarkers in blood and in hair. METHODS Carbohydrate-deficient transferrin (CDT), ethyl glucuronide (EtG), AST, ALT, GGT, MCV were measured in a large sample (n = 562). All people declared no alcohol consumption within the last 3 months. Serum CDT was measured by the ...

in this study, genetic diversity of 30 accessions of the fennel from different cities of iran and other asian and european countries were assessed by using 20 selective aflp primers. totally, from 1127 observed bands, 250 bands were polymorph. e11-m20 primer with 20 bands, also e46-m35 and etg-m20 primers with 8 bands indicated the maximum and minimum numbers of polymorphism, respectively. acco...

BACKGROUND Ethyl glucuronide (EtG) is a minor ethanol metabolite used as a specific marker to document recent alcohol consumption; confirm abstinence in treatment programs, workplaces, and schools; and provide legal proof of drinking. This study examined if bacterial pathogens in urine may enable postsampling synthesis of EtG and ethyl sulfate (EtS) from ethanol, leading to clinical false-posit...
