The SF3b complex in cancer: structural basis, molecular mechanisms, and therapeutic opportunities

Aberrant alternative splicing is increasingly recognized as a fundamental driver of cancer initiation and progression. The splicing factor 3b (SF3b) complex, an essential component of the U2 small nuclear ribonucleoprotein (snRNP), plays a pivotal role in branch point sequence (B...

Triptycene-Cored Double [5]Helicene: Chirality Transfervia the R / S Triptycene Core to P / M Helical Motifs

Abstract A series of double [5]helicenes with a triptycene core were synthesized via photocyclization. Single-crystal X-ray analysis unambiguously confirms these helicenes with an R/S triptycene core and two M/P [5]helicene subunits. Transfer of the central axially helical chiral...

Energy-Transfer-Driven[2 + 2] Cycloaddition: Synthesisof Cyclobutane-Fused Tetracycles from Indenes and Maleimides

Abstract Molecular skeletons containing fused cyclobutane rings are of significant value in drug discovery as they can increase the fraction of sp3 carbons (Fsp3) and impart conformational rigidity. Herein, we report a visible-light photocatalytic strategy for the intermolecular...

Study on mechanical properties and damage evolution of mortar reinforced by mixing basalt, carbon and polyester fibres in pairs

Fibre-reinforced mortar (FRM) has attracted much attention owing to its excellent mechanical properties. To further explore the influence of blended fibres on the mechanical properties and damage evolution of internal cracks in FRM, the effects of blended additions of basalt fibr...

Co–Cu Bimetallic ZIF-67@PDA-Based Fabrics: Trimodal Synergistic Antibacterial Performance for Reusable Protective Textiles

Abstract Protective textiles are essential for public health security, yet conventional textiles only physically filter microorganisms without rapid surface sterilization, easily becoming potential cross-infection sources. Commercial antibacterial variants also suffer from slow s...

Au Single‐Atom Interlayer Bridge Promotes Cross‐Layer Charge Transport and Intrinsic Catalytic Dual‐Sites Activation for Efficient CO 2 Photoreduction

ABSTRACT Layered photocatalysts are attractive for artificial photosynthesis, but their performance is often limited by inefficient charge transport across interlayer gaps and sluggish surface reaction kinetics. Herein, we propose a single‐atom interlayer bridge strategy by intro...

The influence of self-supporting personality on social anxiety in college students: the serial-mediating roles of attention bias and social problem-solving orientation

Social anxiety is highly prevalent among college students and is associated with impaired academic functioning and long-term social maladjustment. Although prior research has documented the adaptive value of self-supporting personality, the specific cognitive-behavioral mechanism...

Construction of Multi-Rate QC-LDPC Codes Based on Permutation Method

This paper proposes a systematic permutation-based construction method for multi-rate quasi-cyclic low-density parity-check (QC-LDPC) codes. We first present a graph-theoretic framework in which any regular QC-LDPC code can be normalized to a canonical base matrix that is uniquel...

Long-Term Evidence of ENSO-Driven Rodent Population Dynamics in a Natural Plague Focus of Southwestern China

Climate variability can modulate zoonotic disease risk by altering interactions among wildlife hosts, vectors, and human environments, yet long-term evidence linking large-scale climate oscillations to natural plague systems remains scarce. We investigated the influence of El Niñ...
