Deletion of Salmonella pathogenicity islands SPI-1, 2 and 3 induces substantial morphological and metabolic alternation and protective immune potential
Published 2025-01-01Get full textThe Salmonella pathogenicity islands (SPIs) play crucial roles in the progression of Salmonella infection. In this study, we constructed an improved λ Red homologous recombination system to prepare single and triple deletion mutants of 3 prominent SPIs (SPI-1, 2, and 3), aiming at the impact of dele...

Construction of Salmonella Pullorum ghost by co-expression of lysis gene E and the antimicrobial peptide SMAP29 and evaluation of its immune efficacy in specific-pathogen-free chic...
Published 2018-01-01Get full textIn this study, a safety enhanced Salmonella Pullorum (S. Pullorum) ghost was constructed using an antimicrobial peptide gene, and evaluated for its potential as a Pullorum disease (PD) vaccine candidate. The antimicrobial peptide SMAP29 was co-expressed with lysis gene E to generate S. Pullorum ghos...

Rapid and Precise Wavelength Determination Approach Based on Visually Patterned Integrated Narrow Bandpass Filters
Published 2019-01-01Get full textWe report a rapid and precise spectral determination approach based on visually patterned integrated narrow bandpass filters. The wavelength of light can be determined accurately even by naked eyes in the aid of the device. The experimental results show that both the light with single wavelength and...

Meander Line Nanoantenna Absorber for Subwavelength Terahertz Detection
Published 2018-01-01Get full textThe detection of terahertz electromagnetic waves is crucial for emerging applications within this frequency band, such as spectroscopy, imaging, and communication. Extending the well-developed uncooled infrared focal plane array technology to terahertz frequency regime would be very attractive, but...

PTEN deficiency reprogrammes human neural stem cells towards a glioblastoma stem cell-like phenotype
Published 2015-12-01Get full textAbstract PTEN is a tumour suppressor frequently mutated in many types of cancers. Here we show that targeted disruption of PTEN leads to neoplastic transformation of human neural stem cells (NSCs), but not mesenchymal stem cells. PTEN-deficient NSCs display neoplasm-associated metabolic and gene exp...
