Non-Invasive Tumor-Naïve Minimal Residual Disease Detection of Liver Cancer by Incorporating Circulating Tumor DNA Features and Alpha-Fetoprotein: A Prospective Study.

Background And Purpose: Liver cancer has a high recurrence rate of 50%~70% for early-stage patients. Minimal residual disease (MRD) is strongly linked to liver cancer early recurrence. Identifying MRD through reliable prognostic biomarkers, such as circulating tumor DNA (ctDNA), could significantly benefit these patients by enabling timely intervention and improved outcomes.

Machine Learning-Assisted Hartree-Fock Approach for Energy Level Calculations in the Neutral Ytterbium Atom.

Data-driven machine learning approaches with precise predictive capabilities are proposed to address the long-standing challenges in the calculation of complex many-electron atomic systems, including high computational costs and limited accuracy. In this work, we develop a general workflow for machine learning-assisted atomic structure calculations based on the Cowan code's Hartree-Fock with relativistic corrections (HFR) theory. The workflow incorporates enhanced ElasticNet and XGBoost algorithms, refined using entropy weight methodology to optimize performance.

Effect of stand age on rhizosphere microbial community assembly of dominant shrubs during sandy desert vegetation restoration.

The rhizosphere microbial community helps govern biogeochemical cycling and facilitates complex plant-soil feedback. Understanding the evolutionary dynamics of microbial community structure and functional genes during vegetation succession is crucial for quantifying and understanding ecosystem processes and functions in restored sandy deserts. In this study, the rhizosphere microbial community structure of 11-66-year-old dominant shrubs in a desert revegetation area was examined using shotgun metagenomic sequencing.

Pulmonary delivery of dual-targeted nanoparticles improves tumor accumulation and cancer cell targeting by restricting macrophage interception in orthotopic lung tumors.

Despite the recognized potential of inhaled nanomedicines to enhance and sustain local drug concentrations for lung cancer treatment, the influence of macrophage uptake on targeted nanoparticle delivery to and within tumors remains unclear. Here, we developed three ligand-coated nanoparticles for pulmonary delivery in lung cancer therapy: phenylboronic acid-modified nanoparticles (PBA-NPs), PBA combined with folic acid (FA-PBA-NPs), and PBA with mannose (MAN-PBA-NPs). In vitro, MAN-PBA-NPs were preferentially internalized by macrophages, whereas FA-PBA-NPs exhibited superior uptake by cancer cells compared to macrophages.

Defects of WFS1-mediated peptide hormones secretion contribute to the manifestations of Wolfram syndrome.

Aims: The study aims to investigate whether WFS1 is involved in the regulation of the exportation and secretion of other peptide hormones, as well as to elucidate the precise molecular mechanisms underlying WS caused by pathogenic mutations in the WFS1 gene.

Materials And Methods: The plasma proteome from the WS patients (n = 2, male) and WFS1-deficient mice (n = 5, male) were analyzed using liquid-chromatography tandem mass spectrometry (LC-MS/MS), while age- and gender-matched healthy individuals and wildtype (WT) mice serve as controls. WFS1-deficient mice were intraperitoneally injected with IGF1 starting from 4 weeks of age.

Hesperidin facilitating gastrointestinal motility by "Gut-brain axis" and "SCF/C-Kit signaling pathways".

Hesperidin shows promising results as a potential feed additive for enhancing gastrointestinal motility in animals. Gastrointestinal function plays a pivotal role in animal growth and the digestibility of dietary nutrients, with gastrointestinal motor function serving as a crucial component. However, limited research has been conducted on the application of hesperidin as a feed additive to promote gastrointestinal motility.

Meta-analysis of the curative effect of sacral nerve magnetic stimulation on neurogenic bladder after spinal cord injury.

Background: The curative effect of sacral nerve magnetic stimulation on the neurogenic bladder (NB) after spinal cord injury (SCI) is unclear. This study made a meta-analysis of the curative effect of sacral nerve magnetic stimulation on the NB after SCI and put forward a theoretical basis for the clinical treatment of this disease.

Methods: The databases of PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, WanFang Data, VIP, and CBM were searched by computer, and the randomized controlled trials of sacral nerve magnetic stimulation in the treatment of NB after SCI were collected.

[5]Helicene Based π-Conjugated Macrocycles with Persistent Figure-Eight and Möbius Shapes: Efficient Synthesis, Chiral Resolution and Bright Circularly Polarized Luminescence.

π-Conjugated chiral shape-persistent molecular nanocarbons hold great potential as chiroptical materials, though their synthesis remains a considerable challenge. Here, we present a simple approach using Suzuki coupling of a [5]helicene building block with various aromatic units, enabling the one-pot synthesis of a series of chiral macrocycles with persistent figure-eight and Möbius shapes. Single-crystal structures of 7 compounds were solved, and 22 enantiomers were separated by preparative chiral HPLC.

Research on dynamic urine volume detection system based on smart flexible textile sensors.

Urine leakage volume is an important indicator reflecting the severity of incontinence in patients. Currently, there are limited smart diapers capable of continuous dynamic monitoring of urine volume. This study developed two types of urine volume sensors, resistive and capacitive, which were integrated with traditional diapers to assess urine leakage levels: mild leakage (0-5 mL), moderate leakage (6-12 mL), and severe leakage (above 12 mL).

The Response of Rhizosphere Microbial C and N-Cycling Gene Abundance of Sand-Fixing Shrub to Stand Age Following Desert Restoration.

Rhizosphere microorganisms play a pivotal role in biogeochemical cycles, particularly in relation to carbon (C) and nitrogen (N) cycles. However, the impact of stand age on the composition of rhizosphere microbial communities and the abundance involved in C and N cycling remains largely unexplored in restoration ecosystems dominated by shrubs of temperate deserts. This study focuses on revealing changes in microbial composition and functional genes in the rhizosphere soil of after revegetation, as well as their response mechanisms to changes in environmental factors.

Simultaneous detection of CaMV35S and NOS using fluorescence sensors with dual-emission silver nanoclusters and catalytic hairpin amplification strategy.

A dual-emission fluorescent biosensing method was developed for simultaneous determination of CaMV35S and NOS in genetically modified (GM) plants. Two designed hairpin DNA (H1, H2) sequences were used as templates to synthesize H1-AgNCs (λ = 570 nm, λ = 625 nm) and H2-AgNCs (λ = 470 nm, λ = 555 nm). By using H1-AgNCs and H2-AgNCs as dual-signal tags, combined with signal amplification strategy of magnetic separation to reduce background signal and an enzyme-free catalytic hairpin assembly (CHA) signal amplification strategy, a novel multi-target fluorescent biosensor was fabricated to detect multiple targets based on FRET between signal tags (donors) and magnetic FeO modified graphene oxide (FeO@GO, acceptors).

Indication of long-range correlations governing city size.

City systems are characterized by the functional organization of cities on a regional or country scale. While there is a relatively good empirical and theoretical understanding of city size distributions, insights about their spatial organization remain on a conceptual level. Here, we analyze empirically the correlations between the sizes of cities (in terms of area) across long distances.
