Mechanisms of RNA alternative splicing dysregulation in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a highly aggressive breast cancer subtype with poor prognosis. RNA alternative splicing dysregulation plays a critical role in the initiation and progression of TNBC. This article systematically introduces the basic process of RNA splicing and then focuses on reviewing the aberrant alternative splicing events and their biological effects in TNBC: 1) Multiple splicing-related factors promote tumor cell proliferation and mediate chemotherapy resistance by regulating the alternative splicing of genes involved in cell survival and drug response; 2) dysregulation of splicing regulatory networks leads to altered splicing of multiple metastasis-related genes, promoting tumor invasion and metastasis; 3) aberrant alternative splicing events participate in tumor progression by affecting the expression of DNA damage repair genes; 4) dysregulation of alternative splicing is also involved in the regulation of tumor immune evasion and stem cell properties.

Enhancing electrochemical performance of lignin-based carbon fibrous aerogels via boron doping.

Self-supported hardwood kraft lignin (HKL)/graphene-based carbon fibrous aerogel (L/GCA) presents a fascinating prospect as the electrode of supercapacitor due to its impress rate capacity and cyclic stability. However, the hydrophobicity nature of L/GCA hampers the ion transfer between the electrode and electrolyte, thereby limiting its electrochemical performance. To address this, we enhanced the electrochemical performance of L/GCA through boron doping based on the improvement of hydrophilicity and the re-arrangement of electron density.

Poly(lactide)/poly(butylene adipate-co-terephthalate)/carbon nanotubes composites with robust mechanical properties, fatigue-resistance and dielectric properties.

A styrene-glycidylmethacrylate-1-allyl-3-vinylimidazole epoxy functionalized ionomer (EFI) was synthesized, and the EFI and carbon nanotubes (CNTs) were co-introduced into poly(lactide)/poly(butylene-adipate-co-terephtalate) (PLA/PBAT) blends to fabricate high performance composites with excellent mechanical properties, fatigue-resistance and dielectric properties. It is revealed that EFI can improve the interaction force between PLA and PBAT by inducing the interfacial crosslink reaction, thereby improving the melt strength of the samples. EFI can also refine the dispersion of CNT in the composites owing to the non-covalent force between EFI and CNT, promote the formation of filler network inside composites, which is demonstrated by DMA and rheological test results.

Toward a Free-Response Paradigm of Decision-Making in Spiking Neural Networks.

Spiking neural networks (SNNs) have attracted significant interest in the development of brain-inspired computing systems due to their energy efficiency and similarities to biological information processing. In contrast to continuous-valued artificial neural networks, which produce results in a single step, SNNs require multiple steps during inference to achieve a desired accuracy level, resulting in a burden in real-time response and energy efficiency. Inspired by the tradeoff between speed and accuracy in human and animal decision-making processes, which exhibit correlations among reaction times, task complexity, and decision confidence, an inquiry emerges regarding how an SNN model can benefit by implementing these attributes.
