Signal integrator function of CXXC5 in Cancer.

CXXC type zinc finger protein 5 (CXXC5) is a member of the ZF-CXXC family and plays a pivotal role in signal integration and information transfer within cell signaling network. CXXC5 acts as a regulator in various physiological processes, and abnormalities in its protein structure or function have been linked to multiple pathological processes. In this article, we correspondingly describe the composition of the ZF-CXXC family, emphatically introducing the features of the CXXC5 gene and protein, review the role of CXXC5 in cellular signaling networks, the physiological and pathological processes associated with CXXC5 dysregulation, and particularly focus on the correlation between CXXC5 and cancers.

Experimental investigation of gas seepage characteristics in coal seams under gas-water-stress function.

Seepage experiences were conducted on coal samples with diverse levels of moisture content, gas pressure, and effective stress to investigate how gas seepage in a coal seam is affected by the interaction of gas, water, and stress. The results of the study revealed the intricate relationship between these factors and their impact on the permeability and seepage behavior of coal. The findings indicate that, with increasing gas pressure, the permeability of coal specimens containing different levels of moisture varies distinctly.

Machine learning-based forecasting of ground surface settlement induced by metro shield tunneling construction.

Urban rail transit systems, represented by subways, have significantly alleviated the traffic pressure brought by urbanization and have addressed issues such as traffic congestion. However, as a commonly used construction method for subway tunnels, shield tunneling inevitably disturbs the surrounding soil, leading to uneven ground surface settlement, which can impact the safety of nearby buildings. Therefore, it is crucial to promptly obtain and predict the ground surface settlement induced by shield tunneling construction to enable safety warnings and evaluations.

The role of heart and neural crest derivatives-expressed protein factors in pregnancy.

Heart and neural crest derivatives-expressed protein 1 (HAND1) and Heart and neural crest derivatives-expressed protein 2 (HAND2), members of the Twist-family of basic Helix-Loop-Helix (bHLH) proteins, act as critical transcription factors that play a key role in various developmental processes, including placental development and fetal growth during pregnancy. This review aims to explore the current understanding of HAND1 and HAND2 in pregnant maintenance and their potential implications for maternal and fetal health. We will summarize the mechanisms of action of HAND1 and HAND2 in pregnancy, their expression regulation and association with pregnancy complications such as preterm birth and preeclampsia.

Coherence-based channel selection and Riemannian geometry features for magnetoencephalography decoding.

Magnetoencephalography (MEG) records the extremely weak magnetic fields on the surface of the scalp through highly sensitive sensors. Multi-channel MEG data provide higher spatial and temporal resolution when measuring brain activities, and can be applied for brain-computer interfaces as well. However, a large number of channels leads to high computational complexity and can potentially impact decoding accuracy.

π-HuB: the proteomic navigator of the human body.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Single-cell epigenetic and clonal analysis decodes disease progression in pediatric acute myeloid leukemia.

Pediatric acute myeloid leukemia (pAML) is a clonal disease with recurrent genetic alterations that affect epigenetic states. However, the implications of epigenetic dysregulation in disease progression remain unclear. Here, we interrogated single-cell and clonal level chromatin accessibility of bone marrow samples from 28 pAML patients representing multiple subtypes using mtscATAC-seq, which revealed distinct differentiation hierarchies and abnormal chromatin accessibility in a subtype-specific manner.

Gate-readout and a 3D rectification effect for giant responsivity enhancement of asymmetric dual-grating-gate plasmonic terahertz detectors.

We experimentally investigated the asymmetric dual-grating-gate plasmonic terahertz (THz) detector based on an InGaAs-channel high-electron-mobility transistor (HEMT) in the gate-readout configuration. Throughout the THz pulse detection measurement on the fabricated device, we discovered a new detection mechanism called the "3D rectification effect" at the positive gate bias application, which is a cooperative effect of the plasmonic nonlinearities in the channel with the diode nonlinearity in the heterobarrier between the InGaAs channel layer and the InAlAs spacer/carrier-supply/barrier layers, resulting in a giant enhancement of the detector responsivity. We also found that an undesired long-tail waveform observed on the temporal pulse photoresponse of the device is due to trapping of carriers to the donor levels in the silicon -doped carrier-supply layer when they tunnel through the barrier to the gate and can be eliminated completely by introducing the so-called inverted-HEMT structure.

Electronic perturbation of Cu nanowire surfaces with functionalized graphdiyne for enhanced CO reduction reaction.

Electronic perturbation of the surfaces of Cu catalysts is crucial for optimizing electrochemical CO reduction activity, yet still poses great challenges. Herein, nanostructured Cu nanowires (NW) with fine-tuned surface electronic structure are achieved via surface encapsulation with electron-withdrawing (-F) and -donating (-Me) group-functionalized graphdiynes (R-GDY, R = -F and -Me) and the resulting catalysts, denoted as R-GDY/Cu NW, display distinct CO reduction performances. electrochemical spectroscopy revealed that the *CO (a key intermediate of the CO reduction reaction) binding affinity and consequent *CO coverage positively correlate with the Cu surface oxidation state, leading to favorable C-C coupling on F-GDY/Cu NW over Me-GDY/Cu NW.

Deciphering the molecular mechanism underlying morphology transition in two-component DNA-protein cophase separation.

Nucleic acid and protein co-condensates exhibit diverse morphologies crucial for fundamental cellular processes. Despite many previous studies that advanced our understanding of this topic, several interesting biophysical questions regarding the underlying molecular mechanisms remain. We investigated DNA and human transcription factor p53 co-condensates-a scenario where neither dsDNA nor the protein demonstrates phase-separation behavior individually.

Theoretical exploration of siloxy carbenes: photogeneration and [2+1] photocyclization mechanisms.

Carbenes are highly reactive intermediates central to various organic transformations, particularly within photochemistry. This study investigates siloxy carbenes generated from acyl silanes a 1,2-silyl shift, focusing on their generation and reactivity in excited states, using the multiconfiguration perturbation theory (CASPT2//CASSCF/PCM). Our findings reveal that the presence of an aryl group conjugated with the carbonyl moiety substantially lowers the excitation energy of the singlet nπ* state, enabling the 1,2-Brook rearrangement to proceed directly on the singlet hypersurface.
