BACKGROUND Women with recurrent ectopic pregnancy (EP) represent a unique cohort of patients in whom diagnostic expertise is paramount. We determined whether recurrent EP is associated with significant differences in patient demographics, clinical presentation, risk factors and surgical findings when compared with primary EP. METHODS A retrospective case-control study of all EPs diagnosed fro...

The quarantine bacterium Clavibacter michiganensis subsp. sepedonicus (Cms) causes bacterial ring rot (BRR) in potato but is difficult to detect, hampering the diagnosis of this disease. ELISA immunoassays have not been widely used to detect Cms because commercially available anti-Cms antibodies detect mainly EPS-producing bacteria and can fail to detect strains that do not produce EPS. In the ...

Exopolymeric substances (EPS) are important for biofilm formation and their chemical composition may influence biofilm properties. To explore these relationships the chemical composition of EPS from Bacillus subtilis NCIB 3610 biofilms grown in sucrose-rich (SYM) and sucrose-poor (MSgg and Czapek) media was studied. We observed marked differences in composition of EPS polymers isolated from all...

BACKGROUND Electroencephalography (EEG) is still a widely used imaging tool that combines high temporal resolution with a relatively low cost. Ag/AgCl metal electrodes have been the gold standard for non-invasively monitoring electrical brain activity. Although reliable, these electrodes have multiple drawbacks: they suffer from noise, such as offset potential drift, and usability issues, for e...

Associations among halotolerance, osmotolerance and exopolysaccharide (EPS) production of 50 Aureobasidium melanogenum strains isolated from various habitats along the coasts of Thailand were compared. Using Fisher’s Exact Test, significant associations were found between halotolerance vs osmotolerance (P = 0.004), halotolerance vs EPS production (P = 0.049) and osmotolerance vs EPS production ...

OBJECTIVES 1) To develop and teach a brief intervention (BI) for "hazardous and harmful" (HH) drinkers in the emergency department (ED); 2) to determine whether emergency practitioners (EPs) (faculty, residents, and physician associates) can demonstrate proficiency in the intervention; and 3) to determine whether it is feasible for EPs to perform the BI during routine clinical care. METHODS T...

Caulobacters are adherent prosthecate bacteria that are members of bacterial biofouling communities in many environments. Investigation of the cell surface carbohydrates produced by two strains of the freshwater Caulobacter crescentus, CB2A and CB15A, revealed a hitherto undetected extracellular polysaccharide (EPS) or capsule. Isolation and characterization of the EPS fractions showed that eac...

Exopolymeric substances (EPS) isolated from a pure culture of the marine bacterium Marinobacter sp. and the marine diatom Skeletonema costatum (axenic) were partially purified, chemically characterized and used as dissolved organic matter (DOM) for the production of macroaggregates. The role of organic particles such as transparent exopolymeric particles (TEP) and Coomassie stained particles (C...

High-level transcription of eps, an operon encoding biosynthesis of an exopolysaccharide virulence factor of the phytopathogen Ralstonia (Pseudomonas) solanacearum, requires the products of at least seven regulatory genes (phcA, phcB, xpsR, vsrA-vsrD, and vsrB-vsrC), which are organized in three converging signal transduction cascades. Because xpsR and the vsrB-vsrC two-component system are the...

The influence of humic acid and alginate, two major components of natural organic matter (NOM), on deposition kinetics of extracellular polymeric substances (EPS) on silica was examined in both NaCl and CaCl(2) solutions over a wide range of environmentally relevant ionic strengths utilizing a quartz crystal microbalance with dissipation. Deposition kinetics of both soluble EPS and bound EPS ex...
