Integration of generalized additive models and hyperspectral imaging for quality prediction in Chaoshan beef meatballs: A comprehensive "raw materials-processing-quality-sensory" model.

Maintaining consistent quality of Chaoshan beef meatballs (CBMs) is challenging due to the intricate production processes and stringent raw material requirements, with no effective method currently available for real-time monitoring during production. In this study, a comprehensive "raw materials-processing-quality-sensory" network model to predict CBMs quality attributes by integrating generalized additive model (GAM) with (HSI) was developed. GAM showed strong predictive performance for key attributes such as the pH (R = 0.

Photoexcited Electro-Driven Reactive Oxygen Species Channeling for Precise Extraction of Biomarker Information from Tumor Interstitial Fluid.

Direct electrochemical detection of miRNA biomarkers in tumor tissue interstitial fluid (TIF) holds great promise for adjuvant therapy for tumors in the perioperative period, yet is limited by background interference and weak signal. Herein, a wash-free and separation-free miRNA biosensor based on photoexcited electro-driven reactive oxygen channeling analysis (LEOCA) is developed to solve the high-fidelity detection in physiological samples. In the presence of miRNA, nanoacceptors (ultrasmall-size polydopamine, uPDA) are responsively assembled on the surface of nanodonors (zirconium metal-organic framework, ZrMOF) to form core-satellite aggregates.

A novel ratiometric BenzoBODIPY-Based fluorescent probe for the detection and imaging of Cysteine in living cells and zebrafish models.

Cysteine (Cys) plays a critical role in various biological processes, including protein synthesis, cellular signaling, and antioxidant defense. However, precise detection of Cys in biological systems remains challenging due to interference from similar thiols such as homocysteine (Hcy) and glutathione (GSH). In this study, we report the synthesis and bioimaging of a novel ratio-type fluorescent probe based on the benzoBODIPY fluorophore, designed for the ratiometric detection of Cys.

Effect of Lanthanum-Aluminum Co-Doping on Structure of Hafnium Oxide Ferroelectric Crystals.

Hafnium oxide (HfO)-based devices have been extensively evaluated for high-speed and low-power memory applications. Here, the influence of aluminum (Al) and lanthanum (La) co-doping HfO thin films on the ferroelectric characteristics of hafnium-based devices is investigated. Among devices with different La/Al ratios, the Al and La co-doped hafnium oxide (HfAlAO) device with 4.

High fidelity detection of miRNAs from complex physiological samples through electrochemical nanosensors empowered by proximity catalysis and magnetic separation.

Electrochemical detection of miRNA biomarkers in complex physiological samples holds great promise for accurate evaluation of tumor burden in the perioperative period, yet limited by reproducibility and bias issues. Here, nanosensors installed with hybrid probes that responsively release catalytic DNAzymes (G-quadruplexes/hemin) were developed to solve the fidelity challenge in an immobilization-free detection. miRNA targets triggered toehold-mediated strand displacement reactions on the sensor surface and resulted in amplified shedding of DNAzymes.

Constraint Coupling of Redox Cascade and Electron Transfer Synchronization on Electrode-Nanosensor Interface for Repeatable Detection of Tumor Biomarkers.

Quantitative analysis of up-regulated biomarkers in pathological tissues is helpful to tumor surgery yet the loss of biomarker extraction and time-consuming operation limited the accurate and quick judgement in preoperative or intraoperative diagnosis. Herein, an immobilization-free electrochemical sensing platform is developed by constraint coupling of electron transfer cascade on electrode-nanosensor interface. Specifically, electrochemical indicator (Ri)-labeled single-stranded DNA on electroactive nanodonor (polydopamine, PDA) can be responsively detached by formation of DNA complex through the recognition and binding with targets.

Feasibility Study of Combining Hyperspectral Imaging with Deep Learning for Chestnut-Quality Detection.

The rapid detection of chestnut quality is a critical aspect of chestnut processing. However, traditional imaging methods pose a challenge for chestnut-quality detection due to the absence of visible epidermis symptoms. This study aims to develop a quick and efficient detection method using hyperspectral imaging (HSI, 935-1720 nm) and deep learning modeling for qualitative and quantitative identification of chestnut quality.

Flower-like Nanozyme with Highly Porous Carbon Matrix Induces Robust Oxidative Storm against Drug-Resistant Cancer.

Reactive oxygen species (ROS) generators are sparking breakthroughs in sensitization and treatment of therapy-resistant tumors, yet the efficacy is drastically compromised by limited substrate concentrations, short lifetimes of free radicals, and restricted oxidative damage. Herein, a flower-like nanozyme with highly permeable leaflets accommodating catalytic metal sites was developed to address the challenges by boosting substrate and product accessibility. In the formation of a zeolite imidazole framework, cobalt ions promoted catalytic polymerization and deposition of polydopamine.

Dual factor coactivatable fluorescent nanosensor with boosted cytoplasmic biomarker accessibility toward selective tumor imaging.

Fluorescent nanosensor-based tumor imaging holds great promise in cancer diagnosis and treatment assistance, yet the signal contrast is heavily hampered by the unspecific/unwanted activation at microscopic regions with a highly restricted local abundance of biomarkers. Herein, we developed an activation boosting strategy by the integration and manipulation of dual-factor coactivation of sensing and lysosome escape facilitated the rise of cytosolic biomarker accessibility. By employing hybrid DNA probes on gold nanoquenchers, ATP sensing initiated conformation switch of the corresponding aptamer units triggered the exposure of a hidden toehold in a loop structure.

A multiallelic indel in the promoter region of the Cyclin-dependent kinase inhibitor 3 gene is significantly associated with body weight and carcass traits in chickens.

Many studies have reported that cyclin-dependent kinase inhibitor 3 (CDKN3) is involved in the cell cycle. However, the function of CDKN3 has not been well elucidated in organisms. In this study, a multiallelic indel caused by a 19-bp fragment and a 2 × 19 bp fragment was shown for the first time to be inserted into the promoter of the CDKN3 gene in 1994 chickens from 9 different breeds.
