Impact of evidence-based nursing on postoperative psychological state, quality of life, and function of affected limbs in breast cancer patients: An observational study.

To analyze the effect of evidence-based nursing on postoperative psychological state, quality of life, and function of affected limbs in breast cancer (BC) patients. This study is a retrospective analysis. The clinical data of 122 BC patients in our hospital were selected and divided into evidence-based group and routine group according to different nursing programs.

Tannase immobilisation by amino-functionalised magnetic FeO-chitosan nanoparticles and its application in tea infusion.

The tannase (from Aspergillus niger) was immobilised by glutaraldehyde conjugation to amino-functionalised chitosan-coated magnetic nanoparticles (FeO-CS nanoparticles). Fourier-transform infrared spectroscopy and thermo-gravimetric analysis showed that chitosan was coated on the surface of magnetic nanoparticles. Transmission electron microscopy indicated that the synthesised nanoparticles (FeO-CS) were almost spherical or ellipsoidal with an average diameter of 5.
