Borophene, a revolutionary two-dimensional (2D) material with exceptional electrical, physical, and chemical properties, holds great promise for high-performance, highly integrated information storage systems. However, its metallic nature and structural instability have significantly limited its practical applications. To address these challenges, hydrogenated borophene has emerged as an ideal alternative, offering enhanced stability and semiconducting properties.

Phenolic acids have health-promoting properties, however, but their low concentrations in limit broader medicinal applications. MYB and bHLH transcription factors activate multiple target genes involved in phenylpropanoid metabolism, thereby enhancing the production of various secondary metabolites. We introduced the MYB transcription factor () or () into and observed that antioxidant activity in transgenic plants increased by 1.

Background: Congenital diarrheas and enteropathies (CODEs) caused by diacylglycerol transferase 1 (DGAT1) mutations often cause disease within 2 weeks after birth. If not treated properly, the disease can be life-threatening; therefore, early diagnosis and rational treatment strategies are essential. This study was conducted to improve the understanding of congenital diarrhea caused by DGAT1 deficiency.

Semen Ziziphi Spinosae (SZS) is a traditional Chinese herbal medicine widely used to treat insomnia and anxiety in clinical practice. Currently, the demand for SZS is increasing every year, but the production of wild SZS is unstable due to environmental factors. Grafting sour jujube scions onto sour jujube or jujube tree stocks can achieve a high production rate within a short period of time.

Article Synopsis
  • Edge states in topological systems are important due to their stability and unique properties, leading to the development of a superconducting-proximitized edge interferometer on the topological insulator TaPdTe.
  • This interferometer realizes the Josephson diode effect (JDE), achieving high efficiency (up to 73%) and ultra-low power consumption while operating under small magnetic fields.
  • Key features of the JDE include the presence of a second-order harmonic in the current-phase relation and antisymmetric transport, indicating the device's effectiveness for future advancements in superconducting quantum technologies.

Article Synopsis
  • The study addresses the environmental issues caused by the excessive use of the antibiotic oxytetracycline (OTC) and introduces a new eco-friendly material for its adsorption.
  • Researchers created diatom-allophane bio-nanocomposites with a unique structure that significantly enhances OTC adsorption, showing a capacity of 219.112 mg·g, which is over five times greater than raw materials.
  • The adsorption process is mainly driven by chemical interactions and works effectively across different pH levels and water conditions, highlighting the potential for these bio-nanocomposites in sustainable environmental cleanup.

Detecting multiple targets in living cells is important in cell biology. However, multiplexed fluorescence imaging beyond two-to-three targets remains a technical challenge. Herein, we introduce a multiplexed imaging strategy, 'sequential Fluorogenic RNA Imaging-Enabled Sensor' (seqFRIES), which enables live-cell target detection via sequential rounds of imaging-and-stripping.

Background: Sodium-dependent glucose transporter (SGLT2) inhibitors (SGLT2i) have been found to have anti-atherosclerotic effects in clinical treatment.

Objectives: The aim of this study was to explore whether angiotensin II (Ang II) induces changes in the expression of Na+/H+ exchanger of cytoplasmic membrane channel proteins (NHE1) and SGLT2 in macrophages and whether dapagliflozin (DAPA), an SGLT2i, protects against Ang II induced macrophage senescence by inhibiting NHE1 activation to alleviate Atherosclerosis (AS).

Methods: After intervention with DAPA plus gavage or feeding them a high-fat diet, the mice's aortas were dissected, and oil red O staining was performed.

The latest discovery of high temperature superconductivity near 80 K in LaNiO under high pressure has attracted much attention. Many proposals are put forth to understand the origin of superconductivity. The determination of electronic structures is a prerequisite to establish theories to understand superconductivity in nickelates but is still lacking.

  • Incontinentia pigmenti (IP) is a rare genetic condition caused by a defect in the IKBKG gene, linked to brain injury from microvascular ischemia, with few treatment options available for its inflammatory phase.
  • A study analyzed data from 41 children with IP in Xi'an, China, focusing on clinical features, imaging, blood analysis, and genetics from 2007 to 2021.
  • Results showed that early signs include neurological damage and significant MRI abnormalities, with many patients exhibiting high eosinophil and platelet counts, indicating microvascular damage in both skin and brain during the acute phase of the condition.*

Einstein-Podolsky-Rosen (EPR) steering is commonly shared among multiple observers by utilizing unsharp measurements. Nevertheless, their usage is restricted to local measurements and does not encompass all nonlocal measurement-based cases. In this work, a method for finding beneficial local measurement settings has been expanded to include nonlocal measurement cases.
