Identification of an RNA-binding perturbing characteristic for thiopurine drugs and their derivatives to disrupt CELF1-RNA interaction.

RNA-binding proteins (RBPs) are attractive targets in human pathologies. Despite a number of efforts to target RBPs with small molecules, it is still difficult to develop RBP inhibitors, asking for a deeper understanding of how to chemically perturb RNA-binding activity. In this study, we found that the thiopurine drugs (6-mercaptopurine and 6-thioguanine) effectively disrupt CELF1-RNA interaction.

Helical-sampled fiber Bragg grating inscribed by a femtosecond laser in a ring core fiber.

The inscription of a helical-sampled fiber Bragg grating (HSFBG) in a ring core fiber (RCF) using a low repetition rate femtosecond laser point-by-point technique is demonstrated. The reflection spectrum exhibits several peak groups attributed to the helical-sampled structure, with the wavelength interval between different groups determined by the helical pitch.

Trailing-edge fringes enable robust aerodynamic force production and noise suppression in an owl wing model.

As one of the unique owl-wing morphologies, trailing-edge (TE) fringes are believed to play a critical role in the silent flight of owls and have been widely investigated using idealized single/tandem airfoils. However, the effect of TE fringes and associated mechanisms on the aeroacoustics of owl wings, which feature curved leading edges, wavy TEs, and several feather slots at the wingtips, have not yet been addressed. In this study, we constructed two 3D owl wing models, one with and one without TE fringes, based on the geometric characteristics of a real owl wing.

Can red tourism lead to spiritual transformation? Evidence from tourists visiting the Red Army Long March Xiangjiang Battle Memorial Park.

The mechanism of spiritual transformation in red tourism plays a key role in facilitating the inheritance of red culture. A survey of 385 tourists of Chinese nationality was conducted to explore the path of red tourism's influence on tourists' spiritual transformation. Based on the stimulus-organism-response theory, this paper explores tourists' environmental perceptions of red tourism activities as special external stimuli, introduces a positive emotion factor, and constructs a path model of red tourism for tourists' positive emotions based on educational function and cultural identity, which ultimately leads to their spiritual transformation.

African swine fever virus M1249L protein antagonizes type I interferon production via suppressing phosphorylation of TBK1 and degrading IRF3.

Cyclic GMP-AMP synthase (cGAS) is a major DNA sensor. The recognition of cytosolic DNA by cGAS triggers a robust innate immune response that restricts the replication of diverse viral pathogens through the type I interferon (IFN) and nuclear factor-κB (NF-κB) pathways. African swine fever virus (ASFV) is a large and complex DNA virus reported to strongly inhibit the cGAS-STING signaling pathway.

Co-located angularly offset fiber Bragg grating pair for temperature-compensated unambiguous 3D shape sensing.

A 10 mm-long three-dimensional shape sensor in a single-mode fiber is described and demonstrated experimentally. The sensor is based on a pair of fiber Bragg gratings inscribed at the same location along the fiber axis but offset along different radial directions away from the fiber center. Each offset grating generates cladding mode resonances over a ${\sim}{20}\;{\rm{nm}}$-wide spectral bandwidth, and the two gratings are also offset in period so that their transmission spectra are separated by 40 nm, and thus non-overlapping and fully distinguishable.

Temperature-compensated fiber directional-bend sensor based on a sandwiched MMF-PMPCF structure.

An optical fiber directional-bend sensor based on an inline Mach-Zehnder interferometer is proposed and demonstrated. The device consists of a piece of a multimode fiber (MMF) splicing with a polarization-maintaining photonic crystal fiber (PMPCF) and sandwiched by lead in/out single-mode fibers (SMFs). Owing to the larger diameter of the MMF, some high-order modes in fiber are efficiently coupled and transmitted through the PMPCF, and finally interfere with each other in the output SMFs.
