Dynamic Covalent Bonds-Mediated Color-Switchable Circularly Polarized Luminescence in Helical Assemblies of Achiral Liquid Crystal Block Copolymer Films.

Circularly polarized luminescence (CPL) film attracted considerable attention in information storage and encryption, three-dimensional display, and chiral recognition. However, due to the limited molecular mobility within thin film, achieving a high asymmetry factor and non-contact modulation of CPL remain challenging. In this work, color-switchable homochiral CPL films with high luminescence asymmetry factor (g~0.

Controllable Circularly Polarized Luminescence with High Dissymmetry Factor via Co-Assembly of Achiral Dyes in Liquid Crystal Polymer Films.

Circularly polarized luminescence (CPL) materials are highly demanded due to their great potential in optoelectronic and chiroptical elements. However, the preparation of CPL films with high luminescence dissymmetry factors (g) remains a formidable task, which impedes their practical application in film-based devices. Herein, a facile strategy to prepare solid CPL film with a high g through exogenous chiral induction and amplification of liquid crystal polymers is proposed.

SpTNF regulates apoptosis and antimicrobial peptide synthesis in mud crab (Scylla paramamosain) during white spot syndrome virus infection.

Tumor necrosis factor (TNF) is an inflammatory cytokine that is important in cell survival, proliferation, differentiation, and death. However, the functions of TNF in the innate immune responses of invertebrates have been less studied. In this study, SpTNF was cloned and characterized from mud crab (Scylla paramamosain) for the first time.

A Modified Technique in Rhinoplasty: A Septal Extension Graft Complex Using Septal Cartilage, Ethmoid Bone, and Auricular Cartilage.

Background: Due to the small and weak septal cartilage of Asians, it is a challenge to obtain ideal tip projection and nose lengthening in this population by performing septal extension grafts with only septal cartilage.

Objectives: The aim of this study was to introduce a septal extension graft complex incorporating nasal septal cartilage, the perpendicular plate of the ethmoid bone, and bilateral auricular cartilage, and to examine its effectiveness in terms of morphological and mechanical support.

Methods: Septal cartilage was harvested under an endoscope according to standard techniques.

SpBNIP3 regulates apoptosis and autophagy in mud crab (Scylla paramamosain) during white spot syndrome virus infection.

BNIP3 (BCL2 and adenovirus E1B 19-kDa-interacting protein 3), which is a pro-apoptotic protein in the BCL-2 family involves a variety of cell signaling pathways, including mitochondrial dysfunction, mitochondrial autophagy, and apoptosis in vertebrates. However, the role of BNIP3 in the regulation of apoptosis and/or autophagy in crustaceans suffering virus infection is still limited. In this study, the mud crab (Scylla paramamosain) BNIP3 (SpBNIP3) was identified and studied to elucidate its association with the white spot syndrome virus (WSSV) infection.
