Incorporating Water Molecules into Highly Accurate Binding Affinity Prediction for Proteins and Ligands.

In the binding process between proteins and ligand molecules, water molecules play a pivotal role by forming hydrogen bonds that enable proteins and ligand molecules to bind more strongly. However, current methodologies for predicting binding affinity overlook the importance of water molecules. Therefore, we developed a model called GraphWater-Net, specifically designed for predicting protein-ligand binding affinity, by incorporating water molecules.

Curcumin's Protective Role in Heatstroke-Induced Acute Liver Injury: Targeting Pyroptosis and Enhancing SIRT1 Expression.

Heatstroke (HS) is a severe systemic condition that significantly impacts organ function, with the liver being particularly vulnerable. Sirtuin 1 (SIRT1), a crucial deacetylase, is implicated in various diseases' pathophysiology. Curcumin, a natural polyphenol, has been shown to modulate SIRT1 activity, offering therapeutic benefits.

Optimized single-bath dyeing of bio-based nylon 56/cotton blends with vat dyes: Mechanistic insights and process enhancements.

Nylon 56/cotton (N/C) blended fabrics have excellent durability and can cater to various clothing needs. However, the quality and value of textile garments are significantly influenced by the dyeing process. Due to variations in the structure and characteristics of nylon 56 and cotton fibers in blended fabrics, achieving consistent coloration is challenging, resulting in noticeable color discrepancies.

MRD-driven phase 2 study of daratumumab, carfilzomib, lenalidomide and dexamethasone in newly diagnosed multiple myeloma.

In newly diagnosed multiple myeloma (NDMM), measurable residual disease (MRD) status is prognostically important, but its role in treatment-decisions remains unclear. In a phase II trial (NCT04113018), we assessed daratumumab, carfilzomib, lenalidomide and dexamethasone (Dara-KRd) induction followed by a next generation sequencing (NGS) based MRD-adapted strategy. The primary endpoint was rate of complete response and stringent complete response (≥CR) after induction.

Rheological properties of polyether polyurethane rubber based magnetorheological elastomers under transverse shear and vertical pressure.

A novel magnetorheological vibration isolator with two operating conditions, horizontal shear and vertical compression, was designed and manufactured. The rheological properties of the energy-dissipating material were directly related to the volume fraction of iron powder in the laminated working unit of the magnetorheological vibration isolator. Aggregation of the carbonyl iron powder (CIP) strongly influenced on the rheological properties of the magnetorheological vibration isolator.

MuSE: A deep learning model based on multi-feature fusion for super-enhancer prediction.

Although bioinformatics-based methods accurately identify SEs (Super-enhancers), the results depend on feature design. It is foundational to representing biological sequences and automatically extracting their key features for improving SE identification. We propose a deep learning model MuSE (Multi-Feature Fusion for Super-Enhancer), based on multi-feature fusion.

Disclosure to Whom Matters: Association Between Disclosure of Sexual Orientation and Mental Health Among Chinese LGB People.

Objective: This study aimed to explore the association between disclosure of one's sexual orientation in different social contexts and mental health outcomes among LGB individuals.

Methods: This study used a nationwide sample of 7867 LGB individuals in the mainland of China.

Results: Findings revealed that the disclosure process was associated with positive consequences in several specific contexts such as schools, workplaces, and close friendships, but not in the family context.

Pan-cancer analysis of oncogenic role of CEP55 and experiment validation in clear cell renal cell carcinoma.

Immunotherapy has emerged as a vital component in the contemporary landscape of cancer treatment. Recent studies have indicated that CEP55 plays an oncogenic role; however, its specific mechanisms in promoting tumor proliferation and its potential value in prognosis and immunotherapy prediction across various cancers remain to be elucidated. CEP55 was significantly overexpressed in 22 cancer types compared with their adjacent normal tissues.

Curcumin ameliorates heatstroke-induced lung injury by activating the PI3K/AKT pathway.

Heatstroke (HS) poses a significant threat to public health. Curcumin, a polyphenolic compound, has been reported to possess anti-inflammatory and antioxidant properties. This study aimed to investigate the potential therapeutic effects of curcumin on HS-induced lung injury and to elucidate its underlying molecular mechanisms.

CellCircLoc: Deep Neural Network for Predicting and Explaining Cell Line-Specific CircRNA Subcellular Localization.

The subcellular localization of circular RNAs (circRNAs) is crucial for understanding their functional relevance and regulatory mechanisms. CircRNA subcellular localization exhibits variations across different cell lines, demonstrating the diversity and complexity of circRNA regulation within distinct cellular contexts. However, existing computational methods for predicting circRNA subcellular localization often ignore the importance of cell line specificity and instead train a general model on aggregated data from all cell lines.

A novel positive modulator of GABA receptor exhibiting antidepressive properties.

γ-Aminobutyric acid (GABA) neurotransmission alterations have been implicated to play a role in depression pathogenesis. While GABA receptor positive allosteric modulators are emerging as promising in clinical practice, their precise antidepressant mechanism remains to be further elucidated. The aim of the present study was to investigate the effects of LY-02, a novel compound derived from the metabolite of timosaponin, on depression in animals and its mechanism.

A sandwich-type electrochemical sensor based on RGO-CeO-Au nanoparticles and double aptamers for ultrasensitive detection of glypican-3.

A sandwich-type electrochemical aptasensor for ultrasensitive detection of glypican-3 (GPC3) was constructed using GPC3 aptamer (GPC3) labelled reduced graphene oxide-cerium oxide-gold nanoparticles (RGO-CeO-Au NPs) as the signal probe and the same GPC3 as the capture probe. The electrochemical redox properties of CeO (Ce/Ce) in the RGO-CeO-Au NPs indicate the electrochemical signals. When the target GPC3 was present, an "aptamer-protein-aptamer" sandwich structure was formed on the sensing interface due to the specific binding between the protein and aptamers, resulting in an increased electrochemical redox signal detected by differential pulse voltammetry (DPV) technique.

Thermo-controlled Water Microenvironment Inducing Fluorescence Enhancement of Chalcone Nanohydrogels for Mitochondrial Temperature Sensing.

Developing aggregation-induced emission (AIE)-based hydrogels that exhibit fluorescence enhancement as to thermal properties is an interesting and challenging task. In this work, we employed the fluorophore 2'-hydroxychalcone (HC), fluorescence properties of which are easily influenced by the excited-state intramolecular proton transfer and twisted intramolecular charge transfer (TICT) effects, to develop a novel type of temperature-sensitive polymers, hydroxychalcone-based polymers (HCPs). By controlling the temperature-dependent water microenvironments in HCPs, the intramolecular hydrogen bonds between water and HCPs can be regulated, thereby influencing the TICT process and leading to thermo-induced fluorescence enhancement, which shows a contrary tendency compared to typical AIEgens that always exhibit fluorescence attenuation as the thermal energy accelerates the molecular motion.
