A fishnet between nasopharyngeal carcinoma and resistance: the competing endogenous RNA network.

Chemotherapy and radiotherapy (chemo-/radiotherapy) have advanced as the main treatment modalities for nasopharyngeal carcinoma (NPC), improving patient survival rates. However, chemo-/radiotherapy resistance in NPC cells has emerged as a key factor contributing to poor prognosis. Recently, competing endogenous RNA networks (ceRNETs) have garnered attention for their potential clinical value in studying chemo-/radiotherapy resistance.

Propensity score matched cohort study on magnesium supplementation and mortality in critically ill patients with HFpEF.

Heart failure with preserved ejection fraction (HFpEF) emerges as a singular subclass of heart failure, bereft of specific therapeutic options. Magnesium, an indispensable trace element, is essential to the preservation of cardiac integrity. However, the association between magnesium supplementation and mortality in HFpEF patients remains unclear.

Cortical arealization of interneurons defines shared and distinct molecular programs in developing human and macaque brains.

Cortical interneurons generated from ganglionic eminence via a long-distance journey of tangential migration display evident cellular and molecular differences across brain regions, which seeds the heterogeneous cortical circuitry in primates. However, whether such regional specifications in interneurons are intrinsically encoded or gained through interactions with the local milieu remains elusive. Here, we recruit 685,692 interneurons from cerebral cortex and subcortex including ganglionic eminence within the developing human and macaque species.

Lattice defect engineering advances n-type PbSe thermoelectrics.

Te-free thermoelectrics have garnered significant interest due to their immense thermoelectric potential and low cost. However, most Te-free thermoelectrics have relatively low performance because of the strong electrical and thermal transport conflicts and unsatisfactory compatibility of interfaces between device materials. Here, we develop lattice defect engineering through Cu doping to realize a record-high figure of merit of ~1.

Over the last decade, genomic and functional studies have provided unprecedented insights into the biology of digestive cancers, identifying genetic drivers of tumor progression and key interaction points of tumor cells with the immune system.

Two dimensional confinement induced discontinuous chain transitions for augmented electrocaloric cooling.

Overheating remains a major barrier to chip miniaturization, leading to device malfunction.

Itaconate transporter SLC13A3 confers immunotherapy resistance via alkylation-mediated stabilization of PD-L1.

Itaconate is a metabolite catalyzed by cis-aconitate decarboxylase (ACOD1), which is mainly produced by activated macrophages and secreted into the extracellular environment to exert complex bioactivity. In the tumor microenvironment, itaconate is concentrated and induces an immunosuppressive response. However, whether itaconate can be taken up by tumor cells and its mechanism of action remain largely unclear.

Allelic transcriptomic profiling identifies the role of PRD-like homeobox genes in human embryonic-cleavage-stage arrest.

Cleavage-stage arrest in human embryos substantially limits the success rate of infertility treatment, with maternal-to-zygotic transition (MZT) abnormalities being a potential contributor. However, the underlying mechanisms and regulators remain unclear. Here, by performing allelic transcriptome analysis on human preimplantation embryos, we accurately quantified MZT progression by allelic ratio and identified a fraction of 8-cell embryos, at the appropriate developmental time point and exhibiting normal morphology, were in transcriptionally arrested status.

Background: Non-human primates (NPHs), such as rhesus macaques, cynomolgus monkeys, and Assamese macaques, play a crucial role in biomedical research. However, baseline cytokine and electrolyte data for these three species, particularly data stratified by age and sex, are limited. Therefore, the aim of this study was to establish and analyze age- and sex-specific cytokine and electrolyte profiles in these three species.

Cu-Ni Oxidation Mechanism Unveiled: A Machine Learning-Accelerated First-Principles and TEM Study.

The development of accurate methods for determining how alloy surfaces spontaneously restructure under reactive and corrosive environments is a key, long-standing, grand challenge in materials science. Using machine learning-accelerated density functional theory and rare-event methods, in conjunction with environmental transmission electron microscopy (ETEM), we examine the interplay between surface reconstructions and preferential segregation tendencies of CuNi(100) surfaces under oxidation conditions. Our modeling approach predicts that oxygen-induced Ni segregation in CuNi alloys favors Cu(100)-O c(2 × 2) reconstruction and destabilizes the Cu(100)-O (2√2 × √2)45° missing row reconstruction (MRR).

Validation Status of Electronic Sphygmomanometers in China: A National Survey.

Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.

Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.

Biomimetic Extracellular Vesicles Containing Biominerals for Targeted Osteoporosis Therapy.

Osteoporosis (OP) is a systemic skeletal disorder characterized by decreased bone mineral density and a heightened risk of fractures. Therapies for OP have primarily focused on balancing bone formation and bone resorption, but enhancing the remineralization of osteoporotic bone is also a key strategy for effective repair. Recent insights into biomineralization mechanisms have highlighted the essential role of mineral-containing extracellular vesicles (EVs) secreted by osteoblasts in promoting bone marrow mesenchymal stromal/stem cell (BMSC) differentiation and initiating matrix mineralization.
