Segmental chromosome aberrations as a prognostic factor of neuroblastoma: a meta-analysis and systematic review.

Background: Segmental chromosome aberrations, defined as presence of aberrations, deletion, or imbalance in the chromosomal arms, have long been considered as a predictor of poor prognosis of patients with neuroblastoma. The objective of this meta-analysis is to quantitively analyze the hazard ratios (HRs) of different whole or segmental chromosome aberrations for overall survival (OS) rate or event-free survival (EFS) rate of patients with neuroblastoma.

Methods: Relevant studies about chromosome, neuroblastoma, predictor, prognosis, and survival published from the inception to April 2023 in the databases of PubMed, Embase, and Web of Science were searched, screened, and reviewed.

IGF2BP3 prevent HMGB1 mRNA decay in bladder cancer and development.

Background: IGF2BP3 functions as an RNA-binding protein (RBP) and plays a role in the posttranscriptional control of mRNA localization, stability, and translation. Its dysregulation is frequently associated with tumorigenesis across various cancer types. Nonetheless, our understanding of how the expression of the IGF2BP3 gene is regulated remains limited.

Tungsten oxide polymorphs and their multifunctional applications.

Owing to the natural abundance, easy availability, high stability, non-stoichiometry, and chemical diversity, considerable interest has been devoted to tungsten oxide (WO) nanomaterials, and many advances have been achieved ranging from traditional catalysts and electronics to emerging artificial intelligence. This review focuses on recent progress of WO polymorphs and their multifunctional applications. The structural diversity and crystal phase transitions of WO and recent advances on the general synthesis of various WO nanostructures are first summarized, since the crystal structure and morphology adjustment obviously affect the physiochemical merits of WO materials.

Evolution of Welding Residual Stresses within Cladding and Substrate during Electroslag Strip Cladding.

Hydrogenation reactors are important oil-refining equipment that operate in high-temperature and high-pressure hydrogen environments and are commonly composed of 2.25Cr-1Mo-0.25V steel.

Concurrence of quantum anomalous Hall and topological Hall effects in magnetic topological insulator sandwich heterostructures.

The quantum anomalous Hall (QAH) effect is a consequence of non-zero Berry curvature in momentum space. The QAH insulator harbours dissipation-free chiral edge states in the absence of an external magnetic field. However, the topological Hall (TH) effect, a hallmark of chiral spin textures, is a consequence of real-space Berry curvature.

A valley valve and electron beam splitter.

Developing alternative paradigms of electronics beyond silicon technology requires the exploration of fundamentally new physical mechanisms, such as the valley-specific phenomena in hexagonal two-dimensional materials. We realize ballistic valley Hall kink states in bilayer graphene and demonstrate gate-controlled current transmission in a four-kink router device. The operations of a waveguide, a valve, and a tunable electron beam splitter are demonstrated.
