Discrimination of Breast Cancer Based on Ultrasound Images and Convolutional Neural Network.

The aim of our study was to establish an artificial intelligence tool for the diagnosis of breast disease base on ultrasound (US) images. A deep learning algorithm Efficient-Det assisted US diagnosis method was developed to determine breast suspicious lesions as benign, malignant, or normal. Totally 1181 US images from 487 patients of our hospital and 694 publicly accessible images were employed for modeling, including 558 benign images, 370 malignant images, and 253 normal tissue images.

Montelukast ameliorated pemetrexed-induced cytotoxicity in hepatocytes by mitigating endoplasmic reticulum (ER) stress and nucleotide oligomerization domain-like receptor protein 3 (NLRP3) activation.

Pemetrexed (PEM) is an effective chemotherapeutic drug used for the treatment of clinical non-small-cell lung cancer (NSCLC) and is reported to induce severe hepatotoxicity. Exploring potential drugs which could counteract the side effects of PEM is of great clinical interest. Here, we aim to examine the beneficial effects of Montelukast, a novel anti-asthma drug, against PEM-induced cytotoxicity in hepatocytes, and to explore the underlying mechanism.

Risk Factors, Recurrence and Short-Term Outcomes for Progressive Cerebral Infarction: A Retrospective Study.

Background: Only a few studies have investigated the risk factors for the prognosis of progressive cerebral infarction (PCI) and the relationship between PCI and cerebral infarction (CI) recurrence.

Objective: The objective of this study is to analyze the risk factors for PCI and PCI prognosis and evaluate the relationship between PCI and CI recurrence, mortality, short-term outcomes.

Methods: The retrospective study included 221 CI patients.

GO@FeO@CuSilicate Composite with a Hierarchical Structure: Fabrication, Microstructure, and Highly Electromagnetic Shielding Performance.

Two nanocomposites with a hierarchical structure (GO@CuSilicate@FeO and GO@FeO@CuSilicate) were fabricated in this paper. These as-synthesized nanocomposites were analyzed for their structural, compositional, and morphological features by X-ray diffraction, scanning electron microscopy (SEM), Raman spectroscopy, and Brunauer-Emmett-Teller methods. SEM images showed that both nanocomposites had a core-shell structure, and their shells were composed of CuSilicate nanoneedle arrays.

Pulmonary embolism caused by postpartum ovarian vein thrombophlebitis after vaginal delivery: Case report and brief review of the literature.

Puerperal ovarian vein thrombophlebitis is a rare pathology. We present the case of a 23-year-old female who presented with fever and cough that occurred after vaginal delivery and persisted after several courses of antibiotics between the 2nd and 20th day postpartum. CT pulmonary angiography revealed right subsegmental pulmonary embolism.

Exciton-Driven Chemical Sensors Based on Excitation-Dependent Photoluminescent Two-Dimensional SnS.

Excitation wavelength-dependent photoluminescence (PL) in two-dimensional (2D) transition-metal chalcogenides enables a strong excitonic interaction for high-performance chemical and biological sensing applications. In this work, we explore the possible candidates in the domain of post-transition-metal chalcogenides. Few-layered 2D p-type tin monosulfide (SnS) nanoflakes with submicrometer lateral dimensions are synthesized from the liquid phase exfoliation of bulk crystals.

Morphological Structure, Rheological Behavior, Mechanical Properties and Sound Insulation Performance of Thermoplastic Rubber Composites Reinforced by Different Inorganic Fillers.

The application area of a sound insulation material is highly dependent on the technology adopted for its processing. In this study, thermoplastic rubber (TPR, polypropylene/ethylene propylene diene monomer) composites were simply prepared via an extrusion method. Two microscale particles, CaCO₃ and hollow glass microspheres (HGW) were chosen to not only enhance the sound insulation but also reinforced the mechanical properties.

Extrusion Foaming of Lightweight Polystyrene Composite Foams with Controllable Cellular Structure for Sound Absorption Application.

Polymer foams are promising for sound absorption applications. In order to process an industrial product, a series of polystyrene (PS) composite foams were prepared by continuous extrusion foaming assisted by supercritical CO₂. Because the cell size and cell density were the key to determine the sound absorption coefficient at normal incidence, the bio-resource lignin was employed for the first time to control the cellular structure on basis of hetero-nucleation effect.

Facile Preparation of Crosslinked PAN Membranes Based on Thiol-Ene Photopolymerization.

To improve the mechanical strength and antipollution properties of membranes, this research presents a facile method to prepare crosslinked polyacrylonitrile (PAN) membranes. This was achieved firstly by radical copolymerization with acrylonitrile, allyl methacrylate and sulfobetaine methacrylamide. Then, the copolymer was crosslinked by a thiol-ene click reaction under UV irradiation.

Asymptomatic hepatobiliary cystadenoma of the hepatic caudate lobe: a case report.

Human hepatobiliary cystadenoma is a rare benign cystic tumor of the liver, and is extremely rare in the caudate lobe. We herein present a case of a 70-year-old male with a hepatobiliary cystadenoma originating from the caudate lobe.
