It had been suggested that the flagella of enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) might contribute to host colonization. In this study, we set out to investigate the adhesive properties of H7 and H6 flagella. We studied the abilities of EHEC EDL933 (O157:H7) and EPEC E2348/69 (O127:H6) flagella to bind to bovine mucus, host proteins such as mucins, and ext...

The study aims to see the effect of contribution, role, and venture capital on MSMEs business development, with quality human resources as a mediating variable. This research was conducted at Islamic banks in city Medan, sample 160 people. As for results obtained based path coefficient test carried out, it found that there were 3 significant items construction t-statistic values ​​> 1.65 p-v...

The locus of enterocyte effacement (LEE) pathogenicity island of enterohemorrhagic Escherichia coli (EHEC) O157:H7 possesses the same genes in identical order and orientation as the LEE of enteropathogenic E. coli (EPEC) O127:H6 but is unable to form attaching and effacing (A/E) lesions or to secrete Esp proteins when it is cloned in an E. coli K-12 background. The A/E phenotype could not be re...

Here, we report the diversity of amantadine-resistant mutants among avian influenza A viruses with pandemic potential (H5, H6, H7, and H9 hemagglutinin subtypes). Drug-resistant variants were not detected among 1979--83 isolates, whereas 31.1% of H5 and 10.6% of H9 strains from Southeast Asia isolated in 2000-04 carried mutations in M2 protein. In North America, resistant variants occurred amon...

Enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) possess a filamentous type III secretion system (TTSS) employed to deliver effector proteins into host cells. EspA is a type III secreted protein which forms the filamentous extension to the TTSS and which interacts with host cells during early stages of attaching and effacing (A/E) lesion formation. By immunofluoresc...

To identify mannosyl (Man)-containing intermediates of the human glycoinositol phospholipid (GPI) anchor pathway and examine their expression in paroxysmal nocturnal hemoglobinuria (PNH), mannolipid products deriving from in vitro guanosine diphosphate [3H]Man labeling of HeLa cell microsomes were characterized. The defined GPI species were correlated with products deriving from in vivo [3H]Man...

Shiga toxin-producing Escherichia coli (STEC) is responsible for several food-borne outbreaks worldwide. In this study, tissue samples of finfish (tilapia, n = 100) and (mullet, 100), twenty human hand swabs from fish sellers fishermen were tested bacteriologically STEC presence. Isolates their antibiotic susceptibility examined the presence eaeA,stx1, stx2 genes. E. identified tissues (36.5% 1...

Two isostructural porphyrin Zr and Hf metal-organic frameworks (FJI-H6 and FJI-H7) are rationally synthesized, and are constructed from 2.5 nm cubic cages. Notably, they both possess high water and chemical stability and can undergo single-crystal to single-crystal transformations to embed Cu2+ ions into the open porphyrin rings. FJI-H6 has a high BET surface area of 5033 m2 g-1. Additionally, ...

The aim of the study is to identify interrelations and interdependencies systemic risk formation in banking sector under influence COVID-19 pandemic. analysis theoretical sources resulted main hypotheses this study: (H1) number cases contributes through an increase household debt; (H2) overdue loans; (H3) changes liquidity capital institutions; (H4) fatal sector, (H5) does not have a significan...

Multiple GSH adducts of the oxidative products of nomifensine (M1-M9) in human hepatocytes and liver microsomes have been identified recently. The current study reports three new types of monooxygenated metabolites of nomifensine identified in human liver microsomes: C-linked hydroxylated metabolites with modifications at the A ring (H1 and H4), an N-hydroxylamine (H6), and nomifensine N-oxides...
