Cyasterone inhibits IL-1β-mediated apoptosis and inflammation via the NF-κB and MAPK signaling pathways in rat chondrocytes and ameliorates osteoarthritisin vivo.

Osteoarthritis is a prevalent global joint disease, which is characterized by inflammatory reaction and cartilage degradation. Cyasterone, a sterone derived from the roots of Cyathula officinalis Kuan, exerts protective effect against several inflammation-related diseases. However, its effect on osteoarthritis remains unclear.

Optimization-based optical diffraction tomography using iODT initialization.

Optical diffraction tomography (ODT) is a label-free and noninvasive technique for biological imaging. However, ODT is only applicable to weakly scattering objects. To extend ODT to the multiple-scattering regime, more advanced inversion algorithms have been developed, including optimization-based ODT (Opti-ODT) and iterative ODT (iODT).

Iterative optical diffraction tomography for illumination scanning configuration.

Optical diffraction tomography (ODT) is used to reconstruct refractive-index distributions from multiple measurements in the object rotating configuration (ORC) or the illumination scanning configuration (ISC). Because of its fast data acquisition and stability, ISC-based ODT has been widely used for biological imaging. ODT typically fails to reconstruct multiply-scattering samples.

Scalable Hermite-Gaussian mode-demultiplexing hybrids.

We propose a Hermite-Gaussian (HG) mode-demulti-plexing hybrid (MDH) for coherent detection of mode-division multiplexed signals. The MDH, which performs multiple functionalities, including demultiplexing, local oscillator splitting, and optical 90-deg mixing, is realized based on the multi-plane light conversion technique. An isosceles right triangle output layout is employed to reduce the number of phase masks to fewer than the number of modes, significantly simplifying the construction of the MDH.

Reconstructing complex refractive-index of multiply-scattering media by use of iterative optical diffraction tomography.

Conventional optical diffraction tomography (ODT) techniques fail in the presence of multiple scattering, and the problem becomes even more challenging when the medium is also lossy. Iterative ODT (iODT), which was shown recently to be more tolerant to multiple scattering than conventional ODT, is here augmented with an error-subtraction (ES) module. Numerical results demonstrate the accuracy and efficiency of iODT with ES for reconstructing multiply-scattering objects with complex refractive index.

Low-crosstalk few-mode EDFAs using retro-reflection for single-mode fiber trunk lines and networks.

Few-mode EDFAs with low channel crosstalk can replace multiple parallel single-mode EDFAs in single-mode fiber trunk lines and networks. Here we proposed a low-crosstalk few-mode EDFA by exploiting the unitary property of the coupling matrix of a symmetric photonic lantern. We experimentally demonstrated a 3-channel few-mode EDFA using retro-reflection of a 3-mode symmetric photonic lantern.

[Risk factors of non-surgical vertebral fracture after percutaneous kyphoplasty of single segment thoracolumbar fracture].

Objective: To investigate the risk factors of non-surgical vertebral fracture after percutaneous kyphoplasty (PKP) in patients with single segment thoracolumbar osteoporotic vertebral compression fracture(OVCF).

Methods: The clinical data of 219 patients with single segment thoracolumbar osteoporotic vertebral compression fracture underwent percutaneous kyphoplasty from January 2010 to December 2015 were retrospectively analyzed. There were 29 cases in non-surgical vertebral body fracture group with 7 males and 22 females aged (67.

A study of stereo microscope measurements based on interpolated feature matching.

Recently, digital stereo microscopes have been becoming increasingly popular in fields such as biomedicine and biotechnology. As such, being able to precisely match left/right feature pairs is critical, which is an important step in stereo matching. We hereby propose a dynamic interpolation method that combines two dimensional calibration and depth information to achieve stereo matching.
