Segmentation of histological images is one of the most crucial tasks for many biomedical analyses including quantification of certain tissue type. However, challenges are posed by high variability and complexity of structural features in such images, in addition to imaging artifacts. Further, the conventional approach of manual thresholding is labor-intensive, and highly sensitive to interand i...

BACKGROUND Congenital heart disease (CHD) represents one of the most prevalent congenital malformations. However, few studies use whole-population screening by colour Doppler ultrasonic diagnostic system to identify CHD among live infants. We estimate the prevalence of CHD and its major risk indicators among infants aged less than 6 months in urban Tianjin, China. METHODS A colour Doppler ult...
Carboxymethyl-quaternized oligochitosan (CMQAOC) was prepared through carboxymethylization and N-quaternization of oligochitosan (OC) which was obtained from chitosan degradation. The structure was confirmed by Fourier transform infrared spectroscopy (FT-IR), H-NMR, and X-ray diffraction (XRD) analysis. The performances for both scale and microbial inhibition of CMQAOC were evaluated by static ...
