Highly sensitive temperature and refractive index sensor based on no-core fiber cascaded with a balloon-shaped bent single-mode fiber.

A highly sensitive temperature and refractive index (RI) sensor based on no-core fiber (NCF) cascaded with a balloon-shaped bent single-mode fiber (BSBSF) is proposed and demonstrated. The NCF can excite higher-order modes which will be concentrated and transmitted into the BSBSF due to the characteristic of self-imaging effect. The BSBSF has an excellent temperature performance due to the high thermo-optical coefficient and thermal expansion coefficient of the polymer coating.

Mechanism of human peripheral blood-derived dendritic cells in the regulation of autophagy in carcinoma cells.

Introduction: Dendritic cells (DC) are involved in immune recognition, response and immunomodulation mechanisms related to the onset of cancer.

Objective: To explore DCs mechanism in the inhibition of autophagy in hepatoma cells.

Methods: Human peripheral blood mononuclear cells were isolated by Ficoll density gradient centrifugation and induced into DCs, which were co-cultured with HepG2 cells by Transwell migration assay.
