N-Methyladenosine Regulates Cilia Elongation in Cancer Cells by Modulating HDAC6 Expression.

Primary cilia are microtubule-based organelles that function as cellular antennae to address multiple metabolic and extracellular cues. The past decade has seen significant advances in understanding the pro-tumorigenic role of N-methyladenosine (mA) modification in tumorigenesis. Nevertheless, whether mA modification modulates the cilia dynamics during cancer progression remains unclear.

CT guided percutaneous drainage for left hepatic subcapsular hematoma after endoscopic retrograde cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography has been widely used in the diagnosis and treatment of biliary and pancreatic diseases. Post-ERCP complications mainly include pancreatitis, infection, bleeding, and perforation. However, post-ERCP left hepatic subcapsular hematoma is a rare and potentially life-threatening complication.

Planar diffractive grating for magneto-optical trap application: fabrication and testing.

The design, fabrication, and demonstration of a planar two-dimensional-crossed reflective diffractive grating are proposed to construct a novel optical configuration, to the best of our knowledge, potentially applied for atom cooling and trapping in a magneto-optical trap. Based on the proposed single-beam single-exposure scheme by means of an orthogonal two-axis Lloyd's mirrors interferometer, we rapidly patterned a ∼1µ period grating capable of providing a uniform intensity of the diffracted beams. The key structural parameters of the grating including the array square hole's width and depth were determined, aiming at providing a high energy of the diffracted beams to perform the atom cooling and trapping.

Two-channel six degrees of freedom grating-encoder for precision-positioning of sub-components in synthetic-aperture optics.

We investigate a novel two-channel grating encoder that can perform simultaneous measurements of six-degree-of-freedom (DOF) motions of two adjacent sub-components of synthetic-aperture optics such as pulse-compression gratings(PCGs) and telescope-primary mirrors. The grating encoder consists of a reading head and two separate gratings, which are attached to the back of the sub-components, respectively. The reading head is constructed such that there two identical optical probes can share the same optical components.

An FPGA Platform for Next-Generation Grating Encoders.

Among various nanometer-level displacement measurement methods, grating interferometry-based linear encoders are widely used due to their high robustness, relatively low cost, and compactness. One trend of grating encoders is multi-axis measurement capability for simultaneous precision positioning and small order error motion measurement. However, due to both lack of suitable hardware data processing platform and of a real-time displacement calculation system, meeting the requirements of real-time data processing while maintaining the nanometer order resolutions on all these axes is a challenge.
