ABSTRACT Diarrhea remains one of the main sources morbidity and mortality in world, a large proportion is caused by diarrheagenic Escherichia coli . In Mongolia, epidemiology E. has not been well studied. A total 238 strains from children with sporadic diarrhea 278 healthy were examined PCR for 10 virulence genes: enteropathogenic (EPEC) eae , tir bfpA ; enterotoxigenic (ETEC) lt st enteroinvasive (EIEC) ipaH enterohemorragic stx1 stx2 enteroaggregative (EAEC) aggR astA EAEC without AggR...
The gold standard for identification of Enteroaggregative Escherichia coli (EAEC) remains the HEp-2 cell adherence test, which is time-consuming and requires specialized facilities. We evaluated usefulness a quantitative biofilm assay to screen EAEC from total 1,042 E. strains children with diarrhea. Bacteria were incubated overnight in high-glucose Dulbecco’s modified Eagle’s medium using polystyrene microtiter plate. plate was stained crystal violet after washing, quantified an...

The reductive desorption of cysteine and 4-mercaptobenzoic acid monolayers formed on polycrystalline single-crystalline gold substrates has been investigated. Three cathodic waves observed at electrodes are correlated with from each small domain the low index faces, i.e. (111), (100) (110), over surface. stability adsorbates differs substantially depending surface crystallographic orientation, in order (111) < (110). Thus, occurs certain potentials, leading to an apparent peak separation...
Four crystal structures of the title complexes have been analyzed by X-ray crystallography. 1: C80H68N17Nd, a = 17.0545(6) Å, c 22.807(3) tetragonal, P4/ncc, Z 4. 2: C80H68N17Gd, 17.399(8) 11.377(6) P4212, 2. 3: C80H70N17OHo, 18.096(5) 11.079(6) 4: C80H70N17OLu, 18.171(3) 10.987(4) P4/nmm, The [LnIIIPc2]- and [NBun4]+ ions in each stack alternately column along 4-fold axis.

When a sinusoidal modulation is superimposed on the rotation speed of rotating disk electrode, corresponding modulated current follows Levich equation closely for sufficiently low ratios frequency to constant center rotational frequency. In this work, response (amplitude and phase) derived general case results experimentally confirmed over wide range Schmidt numbers (230–2100 Sc) reduction Fe+3 Fe+2 in temperature 25°–85°C. Tables are given phase amplitude factors which would be encountered...
The dissemination of difficult-to-treat carbapenem-resistant Enterobacterales (CRE) is great concern. We clarified the risk factors underlying CRE infection mortality in Japan.We conducted a retrospective, multicentre, observational cohort study patients with infections at 28 university hospitals from September 2014 to December 2016, using Japanese National Surveillance criteria. Clinical information, including patient background, type infection, antibiotic treatment, and treatment outcome,...
In Japan, many younger children attending day-care centers tend to frequently experience acute respiratory infections and prolonged otitis media.To evaluate the carriage rate of bacterial pathogens in our district.Nasopharyngeal cultures 156 healthy between ages 1 month 5 years were conducted at two April 1999. The rates four major (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis Staphylococcus aureus) antibiotic susceptibilities isolates examined.Streptococcus H. M....
Electrically conducting π-conjugated copolymers consisting of π-excessive thiophene-2,5-diyl and π-deficient pyridine-2,5-diyl monomer units show a unique cyclic voltammogram with an unusually large potential difference between the doping undoping peaks, their electronic fluorescence spectra support occurrence intramolecular charge transfer showing absorption peaks at lower energy compared those corresponding homopolymers.
A poly(thionine)-modified basal-plane pyrolytic graphite electrode, which can be prepared by a potential-sweep electrolysis of the corresponding monomer in acetonitrile media, shows an excellent electrocatalytic activity for NADH oxidation phosphate buffer solutions (pH 6.9), with activation overpotential is ca. 400 mV lower than that bare electrode.
