Highly sensitive torsion senor based on dual-side-hole fiber Mach-Zehnder interferometer.

We experimentally demonstrate a highly sensitive directional torsion sensor based on a helical dual side-hole fiber (DSHF). The sensor is constructed by splicing a fraction of DSHF in between two short lengths of multi-mode fibers (MMFs), which forms a Mach-Zehnder interferometer (MZI) based on the interference between the core and cladding modes in the DSHF. The middle part of the DSHF is heated and twisted to get a spiral cladding, so that the cladding mode in the DSHF travels along a helical path.

Associations of amylin with inflammatory markers and metabolic syndrome in apparently healthy Chinese.

Background: Cellular and animal studies implicate multiple roles of amylin in regulating insulin action, glucose and lipid metabolisms. However, the role of amylin in obesity related metabolic disorders has not been thoroughly investigated in humans. Therefore, we aimed to evaluate the distribution of circulating amylin and its association with metabolic syndrome (MetS) and explore if this association is influenced by obesity, inflammatory markers or insulin resistance in apparently healthy Chinese.
