Assessment of renal allograft function early after transplantation with isotropic resolution diffusion tensor imaging.

Objectives: To investigate the value of diffusion tensor imaging (DTI) and tractography in renal allografts at the early stage after kidney transplantation.

Methods: This study was approved by the institutional ethical review committee, and written informed consent was obtained. A total of 54 renal allograft recipients 2-3 weeks after transplantation and 26 age-matched healthy volunteers underwent renal DTI with a 3.

[Hyaluronic acid-based carriers for tumor targeted delivery system].

Hyaluronic acid (HA) as anticancer drug carrier has become the new hot point in the field of tumor-targeted drugs delivery system in recent years. Tumor therapeutic agents could be transmitted into cells because of hyaluronic acid innate ability to recognize specific cellular receptors that overexpressed on tumor cells surface. This review introduces the basic properties and physiology foundation of hyaluronic acid.
