This experiment was conducted to determine the significance of the peptide amino acid (PAA) contribution to amino acid (AA) net flux in the portal vein and to evaluate the capacity for peptide absorption in the different segments of the gastrointestinal tract of ruminants. Four sheep (64+/-3 kg BW) were fitted with catheters and blood flow probes, allowing AA net flux measurements across the po...

To explore the pathogenesis of Rhizoctonia solani and its phytotoxin phenylacetic acid (PAA) on maize leaves and sheaths, treated leaf and sheath tissues were analyzed and interpreted by ultra-performance liquid chromatography-mass spectrometry combined with chemometrics. The PAA treatment had similar effects to those of R. solani on maize leaves regarding the metabolism of traumatin, phytosphi...

Escherichia coli strains isolated from sporadic cases of acute diarrhea in children and adults and from children without diarrhea were investigated for the presence of the pAA plasmid. Strains harboring the pAA plasmid were isolated at similar frequencies from children with (19.6%) and without (10.8%) diarrhea and from adults with diarrhea (11.8%). The genotypic and phenotypic virulence markers...

Solubility parameter-dependent drug releasing property is essential in practical drug delivery systems (DDS), and how to combine magnetic nanoparticles(NPs) and suitable polymer coating towards DDS is always a crucial and valuable challenge in biomedical application. Herein, a controllable drug delivery model with a surface having a chemically tunable solubility parameter is presented using hol...

Peracetic acid (PAA) was evaluated as an algae control agent at the City of Modesto, CA Publicly Owned Treatment Works (POTW), during the period of June 2–4, 2003. Algae have been a problem at the POTW for many years and have become an increasing problem as the POTW attempts to increase its treatment capacity. High algae levels entering the chlorine contactor cause high chlorine demand, high TS...

An electro-Fe2+-activated peracetic acid (EC/Fe2+/PAA) process was established for organic dye removal in water. The operation factors such as the PAA dosage, Fe2+ amount, current density, and pH were investigated on methylene blue (MB) synergistic EC/Fe2+/PAA system. Efficient MB decolorization (98.97% 0.06992 min−1) achieved within 30 min under 5.4 mmol L−1 PAA, μmol Fe2+, 15 mA cm−2 intensit...

objective: the aim of the this study was to investigate the prevalence of toxb, paa, lpf and iha adhesion genes in enteropathogenic escherichia coli (epec) isolates lacking in two important adhesion factors, the eaea and bfpa genes. methods: we examined a total of 70 serologically confirmed epec (eaea-, bfpa-) isolates. dna from the isolates was extracted by the phenol-chloroform method. toxb,...

The nanostructure of poly(acrylic acid) (PAA) adsorption layer on the surface of mesoporous-activated carbon HPA obtained by physical activation of residue after supercritical extraction of hops was characterized. This characterization has been done based on the analysis of determination of adsorbed polymer amount, surface charge density, and zeta potential of solid particles (without and in th...
