Radiomics analysis using magnetic resonance imaging of bone marrow edema for diagnosing knee osteoarthritis.

This study aimed to develop and validate a bone marrow edema model using a magnetic resonance imaging-based radiomics nomogram for the diagnosis of osteoarthritis. Clinical and magnetic resonance imaging (MRI) data of 302 patients with and without osteoarthritis were retrospectively collected from April 2022 to October 2023 at Longhua Hospital affiliated with the Shanghai University of Traditional Chinese Medicine. The participants were randomly divided into two groups (a training group, n = 211 and a testing group, n = 91).

Gavage Strategy for Decoction Formula of Traditional Chinese Medicine in Osteosarcoma Model Mice.

Decoction formula is the most commonly used dosage form in traditional Chinese medicine and applied in clinical practice for thousands of years by trans-oral administration, which is characterized by quick effect, easy absorption, and individualized treatment based on the specific syndromes of patients. The quality of the decoction formula is directly responsible for the clinical efficacy of traditional Chinese medicine; therefore, the standardization process of the decoction formula is important to avoid differences in decoction quality caused by subjective factors. Meanwhile, due to the limitations of performing clinical experiments, small animals bearing human diseases, such as mice, are often used in medical research to explore the therapeutic efficacy and comprehensive mechanisms of different interventions, including the decoction formula for traditional Chinese medicine.

Pathological progression of osteoarthritis: a perspective on subchondral bone.

Osteoarthritis (OA) is a degenerative bone disease associated with aging. The rising global aging population has led to a surge in OA cases, thereby imposing a significant socioeconomic burden. Researchers have been keenly investigating the mechanisms underlying OA.

Establishment of Patient-Derived Xenograft Mouse Model with Human Osteosarcoma Tissues.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. Despite the development of new treatment plans in recent years, the prognosis for osteosarcoma patients has not significantly improved. Therefore, it is crucial to establish a robust preclinical model with high fidelity.

Clinical Efficacy of Small Needle Knife Therapy on Stage I-II Frozen Shoulder.

Frozen shoulder is a kind of aseptic inflammatory disease of the shoulder caused by strain, trauma, and other reasons, resulting in shoulder joint pain and limited function. The protocol presented here demonstrates the operation of a small needle knife in treating frozen shoulders, including patient management, material preparation, positioning, operation, and postoperative care. The purpose of this protocol is to relieve the pain and functional limitations and improve the living ability of patients with frozen shoulders.

Left Ventricle Segmentation in Echocardiography with Transformer.

Left ventricular ejection fraction (LVEF) plays as an essential role in the assessment of cardiac function, providing quantitative data support for the medical diagnosis of heart disease. Robust evaluation of the ejection fraction relies on accurate left ventricular (LV) segmentation of echocardiograms. Because human bias and expensive labor cost exist in manual echocardiographic analysis, computer algorithms of deep-learning have been developed to help human experts in segmentation tasks.

MicroRNA-384-5p protects against cardiac hypertrophy via the ALPK3 signaling pathway.

Heart failure is a condition caused by a variety of pathophysiological factors. One important pathological change of chronic heart failure is myocardial hypertrophy. In recent years, several studies have found that dysregulated microRNAs are involved in regulating the pathological process of heart failure.

A novel approach of fabricating monodispersed spherical MoSiBTiC particles for additive manufacturing.

It is very challenging to fabricate spherical refractory material powders for additive manufacturing (AM) because of their high melting points and complex compositions. In this study, a novel technique, freeze-dry pulsated orifice ejection method (FD-POEM), was developed to fabricate spherical MoSiBTiC particles without a melting process. Elemental nanopowders were dispersed in water to prepare a high-concentration slurry, which was subsequently extruded from an orifice by diaphragm vibration and frozen instantly in liquid nitrogen.

Structural transformations of growing thin colloidal crystals in confined space via convective assembly.

The structural evolution of growing thin colloidal crystals in a confined space via the convective assembly technique has been investigated. The thin colloidal crystals were grown in a wedge-shaped cell, where the height of the cell increased with increased crystal growth. Triangle and square patterns, denoted as [111]- and [100]-oriented grains, respectively, were formed alternately as the height of the cell increased.

Decreased Mortality with Beta-Blocker Therapy in HFpEF Patients Associated with Atrial Fibrillation.

Background: There are no proven effective treatments that can reduce the mortality in heart failure with preserved ejection fraction (HFpEF), probably due to its heterogeneous nature which will weaken the effect of therapy in clinical studies. We evaluated the effect of beta-blocker treatment in HFpEF patients associated with atrial fibrillation (AF), which is a homogeneous syndrome and has seldom been discussed.

Methods: This retrospective cohort study screened 955 patients diagnosed with AF and HFpEF.

Effects of Solution Flow on the Growth of Colloidal Crystals.

For the versatile potential applications of colloidal crystals, precisely controlling their growth is required to achieve properties such as high crystallinity and large-area crystals. Because colloidal crystallization is a self-assembly process of dispersed particles in a solution, solution flow directly and markedly changes the behavior of particles. Thus, the effects of solution flow on the growth of colloidal crystals were investigated in the present study.

Small RNA-mediated Cry toxin silencing allows Bacillus thuringiensis to evade Caenorhabditis elegans avoidance behavioral defenses.

Pathogen avoidance behavior protects animal hosts against microbial pathogens. Pathogens have evolved specific strategies during coevolution in response to such host defenses. However, these strategies for combatting host avoidance behavioral defenses remain poorly understood.

Heterogeneous Nucleation of Colloidal Crystals on a Glass Substrate with Depletion Attraction.

The heterogeneous nucleation of colloidal crystals with attractive interactions has been investigated via in situ observations. We have found two types of nucleation processes: a cluster that overcomes the critical size for nucleation with a monolayer, and a method that occurs with two layers. The Gibbs free energy changes (ΔG) for these two types of nucleation processes are evaluated by taking into account the effect of various interfacial energies.

Two-Dimensional Nucleation on the Terrace of Colloidal Crystals with Added Polymers.

Understanding nucleation dynamics is important both fundamentally and technologically in materials science and other scientific fields. Two-dimensional (2D) nucleation is the predominant growth mechanism in colloidal crystallization, in which the particle interaction is attractive, and has recently been regarded as a promising method to fabricate varieties of complex nanostructures possessing innovative functionality. Here, polymers are added to a colloidal suspension to generate a depletion attractive force, and the detailed 2D nucleation process on the terrace of the colloidal crystals is investigated.

Taxol prevents myocardial ischemia-reperfusion injury by inducing JNK-mediated HO-1 expression.

Context: Ischemia/hypoxia and reperfusion impair mitochondria and produce a large amount of reactive oxygen species (ROS), which lead to mitochondrial and brain damage. Furthermore, heme oxygenase-1 (HO-1) as a cytoprotective gene protects cells against ROS-induced cell death in ischemia-reperfusion injury. Induction of HO-1 is involved in cytoprotective effects of taxol.
