Dramatic switchable polarities in conduction type and self-driven photocurrent of BiI via pressure engineering.

The intentional manipulation of carrier characteristics serves as a fundamental principle underlying various energy-related and optoelectronic semiconductor technologies. However, achieving switchable and reversible control of the polarity within a single material to design optimized devices remains a significant challenge. Herein, we successfully achieved dramatic reversible p-n switching during the semiconductor‒semiconductor phase transition in BiI via pressure, accompanied by a substantial improvement in their photoelectric properties.

Multi-Omics Research on Angina Pectoris: A Novel Perspective.

Angina pectoris (AP), a clinical syndrome characterized by paroxysmal chest pain, is caused by insufficient blood supply to the coronary arteries and sudden temporary myocardial ischemia and hypoxia. Long-term AP typically induces other cardiovascular events, including myocardial infarction and heart failure, posing a serious threat to patient safety. However, AP's complex pathological mechanisms and developmental processes introduce significant challenges in the rapid diagnosis and accurate treatment of its different subtypes, including stable angina pectoris (SAP), unstable angina pectoris (UAP), and variant angina pectoris (VAP).

After the epidemic was loosened in early December 2022, the normal medical order gradually restored in China. How much was the impact on the admission and treatment of emergency trauma patients during and after the epidemic? This study aims to compare the differences between trauma patients admitted to the emergency department during and after the COVID-19 pandemic.

Determination of Geographical Origin of Southern Shaanxi Congou Black Teas Using Sensory Analysis Combined with Gas Chromatography-Ion Mobility Spectrometry.

Southern Shaanxi is one of China's high-quality congou black tea production areas. However, the differences in geography, cultivation, and management techniques and production processes lead to uneven qualities of southern Shaanxi congou black tea in different production areas. This study used sensory analysis combined with gas chromatography-ion mobility spectrometry (GC-IMS) to determine southern Shaanxi congou black teas' geographical origin and volatile fingerprints to prevent economic losses caused by fraudulent labeling.

The cGAS-STING/PERK-eIF2α: Individual or Potentially Collaborative Signaling Transduction in Cardiovascular Diseases.

Over the past several decades, a canonical pathway called the cyclic GMP-AMP (cGAMP) synthase (cGAS)-stimulator of interferon genes (STING) mediating type I interferon (IFN) release via TANK-binding kinase 1(TBK1) / IFN regulatory factor 3 (IRF3) pathway has been widely investigated and characterized. Unexpectedly, recent studies show that the cGAS-STING noncanonically activates the protein kinase RNA-like ER kinase (PERK)-eukaryotic initiation factor 2α (eIF2α), an essential branch of unfolded protein response (UPR), even before the activation of the TBK1/IRF3 signaling. Additionally, we found that the PERK could regulate the STING signaling besides being modulated by upstream cGAS-STING.

Decoding β-catenin associated protein-protein interactions: Emerging cancer therapeutic opportunities.

The hyperactive Wnt/β-catenin signaling circuit has been proven to be closely related to the progression of various cancers, with β-catenin serving as a central regulator of pro-tumorigenic processes. Preclinical evidences strongly support β-catenin as a promising therapeutic target. However, it has long been considered "undruggable" due to challenges such as the lack of crystal structures for its N- and C-terminal domains, high mutation rates, and limited availability of inhibitors.

Rapid detection of carbapenemase production in using phenotypic tests based on colorimetric microtube assay.

Antibiotic resistance, particularly carbapenem resistance, poses a significant global health threat due to the limited availability of effective antibiotics.

This study aimed to evaluate several phenotypic tests, including the Carba NP test (CNPt), Carba NP-direct test (CNPd), and Blue-Carba test (BCT), for their effectiveness in rapidly detecting carbapenemase production in .

Evaluation and correction methods for geometric errors of hydrostatic thrust bearings.

The value and direction angle of the perpendicularity error of the thrust surface and bearing bush in hydrostatic thrust bearings directly affect the motion accuracy. In this paper, a rapid onsite measurement method and evaluation model for the value and direction angle of the perpendicularity error of the thrust surface and bearing bush in hydrostatic thrust bearings are presented. The method is validated by comparing experimental measurements with those obtained using a CMM.

TRIM4 enhances small-molecule-induced neddylated-degradation of CORO1A for triple negative breast cancer therapy.

As a critical member of the Coronin family, Coronin 1A (CORO1A) plays a crucial role in the progression of triple-negative breast cancer (TNBC). However, CORO1A is typically considered "undruggable" due to its smooth surface and complex protein-protein interactions (PPIs). Molecular glues have emerged as one of the most effective strategies to rapidly degrade such "undruggable" targets.

Review and revamp of compositional data transformation: A new framework combining proportion conversion and contrast transformation.

Due to the development of next-generation sequencing technology and an increased appreciation of their role in modulating host immunity and their potential as therapeutic agents, the human microbiome has emerged as a key area of interest in various biological investigations of human health and disease. However, microbiome data present a number of statistical challenges not addressed by existing methods, such as the varying sequencing depth, the compositionality, and zero inflation. Solutions like scaling and transformation methods help to mitigate heterogeneity and release constraints, but often introduce biases and yield inconsistent results on the same data.
