Predictive Value of Albumin to Fibrinogen Ratio and CALLY Index for Diagnosis of Ulcerative Colitis and Mucosal Healing After Vedolizumab Treatment.

Purpose: The albumin to fibrinogen ratio (AFR), a biomarker associated with inflammatory, nutritional, and coagulation status, and the CALLY index, a biomarker combining C-reactive protein, albumin, and lymphocyte count, have been suggested to correlate with prognosis in a variety of diseases in previous studies; however, studies of these two markers in ulcerative colitis (UC) are lacking. The aim of this study was to evaluate the clinical significance of AFR and CALLY index in UC.

Methods: The study included 109 UC patients and 126 healthy controls.

Promising Nanoparticles-Based Oral Therapy for Effective Inhibition of Hepatocellular Carcinoma with Portal Vein Tumor Thrombus.

Portal vein tumor thrombus (PVTT) is a poor prognostic factor for hepatocellular carcinoma (HCC) patients, highlighting the need for an oral drug delivery system that combines convenience, simplicity, biosafety, and improved patient compliance. Leveraging the unique anatomy of the portal vein and insights from single-cell RNA sequencing of the PVTT tumor microenvironment, we developed oral pellets using CaCO@PDA nanoparticles (NPs) encapsulating both doxorubicin hydrochloride and low molecular weight heparin. These NPs target the tumor thrombus microenvironment, aiming to break down the thrombus barrier and turn the challenge of portal vein blockage into an advantage by enhancing drug delivery efficiency through oral administration.

Structure of an LGR dimer - an evolutionary predecessor of glycoprotein hormone receptors.

The glycoprotein hormones of humans, produced in the pituitary and acting through receptors in the gonads to support reproduction and in the thyroid gland for metabolism, have co-evolved from invertebrate counterparts . These hormones are heterodimeric cystine-knot proteins; and their receptors bind the cognate hormone at an extracellular domain and transmit the signal of this binding through a transmembrane domain that interacts with a heterotrimeric G protein. Structures determined for the human receptors as isolated for cryogenic electron microscopy (cryo-EM) are all monomeric despite compelling evidence for their functioning as dimers .

CGPDTA: An Explainable Transfer Learning-Based Predictor With Molecule Substructure Graph for Drug-Target Binding Affinity.

Identifying interactions between drugs and targets is crucial for drug discovery and development. Nevertheless, the determination of drug-target binding affinities (DTAs) through traditional experimental methods is a time-consuming process. Conventional approaches to predicting drug-target interactions (DTIs) frequently prove inadequate due to an insufficient representation of drugs and targets, resulting in ineffective feature capture and questionable interpretability of results.

The characterization and structural basis of a human broadly binding antibody to HBV core protein.

Hepatitis B virus (HBV) core protein (HBc) plays a crucial role in the virus life cycle, making it an important detection marker for HBV infection and a potential target for treatment. However, several commercially available monoclonal antibodies (mAbs) or polyclonal antibodies (pAbs) targeting HBc have certain limitations in detecting HBV across different genotypes in various biochemical assays, such as enzyme-linked immunosorbent assay, western blot, immunofluorescence assay, flow cytometry, and immune spot assay. In this study, we identified 12 human anti-HBc mAbs and evaluated their potential application in multiple biochemical assays.

Amphiphilic Janus Nanoparticles for Effective Treatment of Bacterial Pneumonia by Attenuating Inflammation and Targeted Bactericidal Capability.

Introduction: -induced pneumonia is marked by considerable infiltration of inflammatory cells and biofilm formation, which causes acute and transient lung inflammation and infection. Nevertheless, the discovery of alternative preventative and therapeutic methods is essential due to the high mortality rates in clinical settings and the resistance of infection to multiple medications.

Purpose: In this research, we constructed amphiphilic Janus nanoparticles (JNPs, denoted as SSK1@PDA/CaP@CIP), loaded with hydrophobic SSK1, a β-galactosidase (β-gal)-activated prodrug for reducing macrophages, and hydrophilic ciprofloxacin (CIP), a classic antibiotic for treating infection.

Realization of nonreciprocal photon statistics by manipulating the quantum nonlinearity of cold atoms in an asymmetric cavity.

In a strongly coupled cavity quantum electrodynamics (QED) system, the second-order correlation function g(τ) of the transmitted probe light from the cavity is determined by the nonlinearity of the atom in the cavity. Therefore, the system provides a platform for controlling the photon statistics by manipulating nonlinearity. In this paper, we experimentally demonstrate nonreciprocal quantum statistics in a cavity QED system with several atoms strongly coupled to an asymmetric optical cavity, which is composed of two mirrors with different transmittivities.

GDMol: Generative Double-Masking Self-Supervised Learning for Molecular Property Prediction.

Background: Effective molecular feature representation is crucial for drug property prediction. Recent years have seen increased attention on graph neural networks (GNNs) that are pre-trained using self-supervised learning techniques, aiming to overcome the scarcity of labeled data in molecular property prediction. Traditional GNNs in self-supervised molecular property prediction typically perform a single masking operation on the nodes and edges of the input molecular graph, masking only local information and insufficient for thorough self-supervised training.

Research and application on modeling and landing point prediction technology for water jet trajectory of fire trucks under large-scale scenarios.

To let water jets land at the fire, pitch angle of the fire monitor has to be adjusted manually with successive rounds, which seriously affects the efficiency of fire extinguishing. To improve the efficiency, this paper proposes a technology for water jet trajectory modeling and landing point prediction to help with extinguishing automatically. Considering fragmentation and atomization of water jets, trajectories are analyzed and the predicted trajectory is closer to the real situation.
