Avian pathogenic Escherichia coli (APEC) causes colibacillosis in avians, resulting considerable losses the poultry industry. APEC showed zoonotic potential initially related to fact that serves as reservoir of virulence genes and antibiotic resistance for other E. coli. Thus, we determine serotypes, phylogenetic groups, distribution, profiles isolates eastern China. A total 230 were isolated from diseased chicken duck with typical symptoms. Serotyping identified O78 (44.78%) was predominant...
Inappropriate use of antibiotics has accelerated to the emergence multidrug-resistant bacteria, becoming a major health threat. Moreover, bacterial biofilms contribute antibiotic resistance and prolonged infections. Bacteriophage (phage) therapy may provide an alternative strategy for controlling In this study, broad-host-range phage, SHWT1, with lytic activity against Salmonella was isolated, characterized evaluated therapeutic efficacy in vitro vivo . Phage SHWT1 exhibited specific...
The axial resolution of confocal microscopy is not only dependent on optical characteristics but also the utilized peak extraction algorithms. In previous evaluations algorithms, sample surface height generally assumed to be zero, and sampling-noise-induced uncertainty was analyzed. Here we propose a surface-height-dependent (SHD) evaluation model that takes combined considerations noise for comparisons algorithms' performances. Monte Carlo simulations were first conducted centroid algorithm...
Owing to their high practicability, solar PV/T (photovoltaic/thermal) collectors have attracted considerable attention from researchers in both photovoltaic and solar-thermal fields worldwide. In this study, we designed constructed a novel solar-cooled system. Through experimental methods, conducted an in-depth investigation of its thermal electrical output characteristics developed mathematical models for performance performance. Finally, validated the data against simulations. The results...
Salmonella has been known as an important zoonotic pathogen that can cause a variety of diseases in both animals and humans. Poultry are the main reservoir for serovars Pullorum ( S . Pullorum), Gallinarum Gallinarum), Enteritidis Enteritidis), Typhimurium Typhimurium). The conventional serotyping methods differentiating complicated, time-consuming, laborious, expensive; therefore, rapid accurate molecular diagnostic needed effective detection prevention contamination. This study developed...
Oriented strand board is a widely used construction material responsible for substantial portion of the fire load many buildings. To accurately model response oriented to fire, thermogravimetric analysis, differential scanning calorimetry, and microscale combustion calorimetry tests were carried out construct thermal decomposition using numerical solver, ThermaKin, hill climbing optimization algorithm. The included single-step water vaporization reaction four consecutive reactions...
Background Spot fires play a significant role in the rapid spread of wildland and wildland–urban interface fires. Aims This paper presents an experimental modelling study on flaming smouldering burning wood firebrands under forced convection. Methods The firebrand experiments were conducted with different wind speeds sizes. Key results rate convection is quantified by pyrolysis rate, char oxidation convective term. projected area correlated diameter, density, speed, or burning. A surface...
Endothelial progenitor cell (EPC) transplantation is a safe and effective method to treat acute myocardial infarction (AMI). However, oxidative stress leads the death of large number EPCs in early stage transplantation, severely weakening therapeutic effect. Previous studies demonstrated that microRNAs regulate biological function EPCs. The aim current study was investigate effect microRNA on under stress. Quantitative reverse transcription PCR performed detect expression miR-126,...

Fast and accurate peak wavelength extraction of chromatic confocal signals is vital importance for efficient measurement. Existing algorithms do not effectively balance calculation efficiency accuracy. For example, centroid have high computational but low accuracy; model-based fitting accuracy efficiency. In this paper, a fast mean-shift vector based algorithm proposed. algorithm, the initial preset with algorithm; then corresponding calculated, after which, new can be calculated by shifting...
High operating temperature mid-wavelength InAs/GaSb superlattice infrared photodetectors with a single heterojunction structure grown by metal–organic chemical vapor deposition are reported. By inserting fully-depleted wider-gap barrier layer between the absorber and p-contact, “diffusion-limited” behavior has been achieved for “PNn” device, in contrast to conventional pin homojunction device. The PNn device 50% cutoff wavelength of 4.5 μm exhibited dark current 2.05 × 10−4 A/cm2 peak...
The inappropriate use of cephalosporins lead to the occurrence and global spread bacteria resistant these antimicrobials.
