Development of polysaccharide based intelligent packaging system for visually monitoring of food freshness.

With the increased awareness on food freshness and food quality among consumers, the intelligent packaging films that can visually monitor the freshness of packaged foods by observing the color changes of packaging materials are gradually drawing more and more attentions. In this paper, various colorimetric indicators, types of polysaccharides as film-forming materials, production methods, freshness monitoring application, along with the future development of different intelligent packaging films are illustrated detailedly and deeply. Natural pH sensitive indicators such as anthocyanin, alizarin, curcumin, betaines and chlorophylls, as well as the gases sensitive indicators (hydrogen sulfide sensitive indicators and ethylene sensitive indicators) are the most widely used indicators for monitoring of food freshness.

Development and validation of a clinical risk score nomogram for predicting voriconazole trough concentration above 5 mg/L: a retrospective cohort study.

A modified approach of the agricultural grey water footprint considering the nitrogen fixation effect of crops in China.

The rapidly growing demand for food in human societies has led to the extensive use of fertilizers, significantly contributing to water pollution. Grey water footprints (GWF) serve as a crucial method for measuring Non-point Source (NPS) pollution, particularly in agriculture. Traditional assessments of agricultural GWF neglect biologically fixed nitrogen and the use of organic fertilizers.

From Bi-Level to One-Level: A Framework for Structural Attacks to Graph Anomaly Detection.

The success of graph neural networks stimulates the prosperity of graph mining and the corresponding downstream tasks including graph anomaly detection (GAD). However, it has been explored that those graph mining methods are vulnerable to structural manipulations on relational data. That is, the attacker can maliciously perturb the graph structures to assist the target nodes in evading anomaly detection.

This article primarily utilizes the Revealed Comparative Advantage (RCA) Index, and Trade Complementarity (TC) index to examine the trade comparative advantage, and the complementary of twenty major agricultural products between China and Vietnam from 2012 to 2021. The study results showed that Vietnam and China frequently exchange agricultural products.

The Balance Effect of π-π Electronic Coupling on NIR-II Emission and Photodynamic Properties of Highly Hydrophobic Conjugated Photosensitizers.

Deep NIR organic phototheranostic molecules generally have large π-conjugation structures and show highly hydrophobic properties, thus, forming strong π-π stacking in the aqueous medium, which will affect the phototheranostic performance. Herein, an end-group strategy is developed to lift the performance of NIR-II emitting photosensitizers. Extensive characterizations reveal that the hydrogen-bonding interactions of the hydroxyl end group can induce a more intense π-π electronic coupling than the chlorination-mediated intermolecular forces.

Intramolecular Charge Transfer of Gold Nanoclusters for pH Indicating.

The investigation of the intramolecular charge transfer (ICT) process of gold nanoclusters (AuNCs) is critical to understand the unique features of the nanomaterials, which also benefits their further applications. Herein, 6-methyl-2-thiouracil (CH-2-TU) and polyvinylpyrrolidone (PVP)-stabilized AuNCs are prepared, and the ICT behaviors are carefully studied. Protonation or deprotonation of the ligands around AuNCs could be used to regulate the ICT state, influencing the electron distribution and band gap.

The lysine 2-hydroxyisobutyrylome of Helicobacter pylori: Indicating potential roles of lysine 2-hydroxyisobutyrylation in the bacterial metabolism.

Helicobacter pylori (H. pylori) is a pathogen which colonizes the stomach, causing ulcers, chronic gastritis and other related diseases. Protein post-translational modifications (PTMs) in bacteria mainly include glycosylation, ubiquitination, nitrosylation, methylation, phosphorylation and acetylation, all of which have divergent functions in the physiology and pathology of the bacterium.

Response of Spider and Epigaeic Beetle Assemblages to Overwinter Planting Regimes and Surrounding Landscape Compositions.

The rotation patterns of summer rice-winter oil seed rape and summer rice-winter fallow are the main planting regimes in the rice ecosystem in southern China. However, the impact of local rotation patterns and landscape factors on the overwintering conservation of predators in spider and epigaeic beetle assemblages remains poorly understood. Here, we investigate the diversity and density of spiders and beetles over two consecutive winters (2019/2020 and 2020/2021), focusing on the impact of two rotation patterns (rice-fallow and rice-oilseed rape) and surrounding landscape compositions on predator diversity.

Associated Risk Factors and Diagnostic Value of Fiberoptic Bronchoscopy for Protracted Bacterial Bronchitis in Children.

Objective: Untreated protracted bacterial bronchitis (PBB), a chronic wet cough prevalent in children, may lead to chronic suppurative lung disease.

Thus, we assessed the diagnostic value of fiberoptic bronchoscopy (FOB) and the risk factors associated with PBB.

Wash-Free and High-Contrast Imaging of Single-Nucleotide Variation in Single Cells Using Transcription-Amplified Light-Up RNA Aptamer.

Single-nucleotide variation (SNV) imaging can indicate cellular heterogeneity and spatial pattern, but it remains challenging to produce high-gain signal while also yielding single-nucleotide resolution. Herein, we developed a light-up strategy for visualizing SNVs based on transcription amplification, enabling wash-free and high-contrast imaging of SNVs inside cells. The discrimination of SNVs is achieved by ligase-assisted transcription reaction.

HS-removing UiO-66 MOFs for sensitized antibacterial therapy.

Antibiotic tolerance is implicated in difficult-to-treat infections and the development and spread of antibiotic resistance. The high storage capacities and excellent biocompatibilities of UiO-66-based metal-organic frameworks (MOFs) have made them emerging candidates as drug-delivery vectors. In view of hydrogen sulfide (HS) having been associated with the development of intrinsic resistance to antibacterial agents, we designed a strategy to potentiate existing antibiotics by eliminating bacterial endogenous HS.
