Growths of SiC Single Crystals Using the Physical Vapor Transport Method with Crushed CVD-SiC Blocks Under High Vertical Temperature Gradients.

A recent study reported the rapid growth of SiC single crystals of ~1.5 mm/h using high-purity SiC sources obtained by recycling CVD-SiC blocks used as materials in semiconductor processes. This method has gained attention as a way to improve the productivity of the physical vapor transport (PVT) method, widely used for manufacturing single crystal substrates for power semiconductors.

Neuroprotective Effects of STAT3 Inhibitor on Hydrogen Peroxide-Induced Neuronal Cell Death via the ERK/CREB Signaling Pathway.

This study investigates the neuroprotective potential of STAT3 inhibition in reducing oxidative stress-induced neuronal damage and apoptosis, a major factor contributing to the onset and progression of neurodegenerative diseases, including Alzheimer's disease (AD). Our findings demonstrate that STAT3 inhibitors significantly enhance cell survival and reduce apoptosis in SH-SY5Y cells exposed to hydrogen peroxide. These protective effects are mediated through the ERK/CREB signaling pathway rather than direct suppression of STAT3 phosphorylation.

Loss of phospholipase Cγ1 suppresses hepatocellular carcinogenesis through blockade of STAT3-mediated cancer development.

Phospholipase C gamma 1 (PLCγ1) plays an oncogenic role in several cancers, alongside its usual physiological roles. Despite studies aimed at identifying the effect of PLCγ1 on tumors, the pathogenic role of PLCγ1 in the tumorigenesis and development of hepatocellular carcinoma (HCC) remains unknown. To investigate the function of PLCγ1 in HCC, we generated hepatocyte-specific PLCγ1 conditional knockout (PLCγ1 ; Alb-Cre) mice and induced HCC with diethylnitrosamine (DEN).

The acidic tumor microenvironment enhances PD-L1 expression via activation of STAT3 in MDA-MB-231 breast cancer cells.

Tumor acidosis, a common phenomenon in solid cancers such as breast cancer, is caused by the abnormal metabolism of cancer cells. The low pH affects cells surrounding the cancer, and tumor acidosis has been shown to inhibit the activity of immune cells. Despite many previous studies, the immune surveillance mechanisms are not fully understood.

Targeted drug release system based on pH-responsive PAA-POSS nanoparticles.

An amphipathic PAA-POSS@DOX drug delivery system that responds sensitively to pH changes in the cancer microenvironment has been developed using a nanoparticle based on inorganic polyhedral oligomeric silsesquioxane (POSS). POSS was introduced to the carboxylic acid group of polyacrylic acid to which doxorubicin anticancer drug was loaded to prepare 480 ± 192 nm self-assembled nanoparticles. PAA-POSS had a high loading efficiency of over 75% and doxorubicin was quickly released to the target area responding sensitively to weakly acidic conditions.

3D Vehicle Trajectory Extraction Using DCNN in an Overlapping Multi-Camera Crossroad Scene.

The 3D vehicle trajectory in complex traffic conditions such as crossroads and heavy traffic is practically very useful in autonomous driving. In order to accurately extract the 3D vehicle trajectory from a perspective camera in a crossroad where the vehicle has an angular range of 360 degrees, problems such as the narrow visual angle in single-camera scene, vehicle occlusion under conditions of low camera perspective, and lack of vehicle physical information must be solved. In this paper, we propose a method for estimating the 3D bounding boxes of vehicles and extracting trajectories using a deep convolutional neural network (DCNN) in an overlapping multi-camera crossroad scene.

Insulin smart drug delivery nanoparticles of aminophenylboronic acid-POSS molecule at neutral pH.

Self-regulated "smart" insulin administration system that mimic pancreatic endocrine function would be highly desirable for diabetes management. Here, a glucose-responsive continuous insulin delivery system is developed, where novel polyhedral oligosilsesquioxane (POSS) modified with 3-aminophenylboronic acid (APBA) were used to encapsulate insulin (insulin entrapment efficiency: 73.2%) to prepare a fast response, high stability, good distribution, and excellent biocompatible system.

Extracellular Acidosis Promotes Metastatic Potency via Decrease of the Circadian Clock Gene in Breast Cancer.

Circadian oscillation is an essential process that influences many physiological and biological mechanisms and a decrease of circadian genes is associated with many diseases such as cancer. Despite many efforts to identify the detailed mechanism for decreasing circadian genes and recovering reduced circadian genes in cancer, it is still largely unknown. We found that BMAL1 was reduced in tumor hypoxia-induced acidosis, and recovered by selectively targeting acidic pH in breast cancer cell lines.

Successful management of proteinuria and systemic hypertension in a dog with renal cell carcinoma with surgery, telmisartan, and amlodipine.

Dysfunction of Microglial STAT3 Alleviates Depressive Behavior via Neuron-Microglia Interactions.

Neuron-microglia interactions have a crucial role in maintaining the neuroimmune system. The balance of neuroimmune system has emerged as an important process in the pathophysiology of depression. However, how neuron-microglia interactions contribute to major depressive disorders has been poorly understood.

Secreted frizzled-related protein 5 suppresses inflammatory response in rheumatoid arthritis fibroblast-like synoviocytes through down-regulation of c-Jun N-terminal kinase.

Objective: This study was performed to investigate the effect of secreted frizzled-related protein 5 (Sfrp5), a novel anti-inflammatory adipokine that competes with the frizzled proteins for Wnt binding, on inflammatory response and the c-Jun N-terminal kinase (JNK) signalling pathway in RA.

Methods: Expression of Sfrp5 mRNA in peripheral blood mononuclear cells (PBMCs) and fibroblast-like synoviocytes (FLSs) from patients with RA and OA was determined using real-time quantitative PCR (qPCR). Sfrp5 RNA interference (RNAi) plasmids were transfected to abrogate Sfrp5 expression in RA FLSs, and adenovirus containing the Sfrp5 transcript was delivered into RA FLSs to strengthen Sfrp5 expression.

Active tuberculosis risk with tumor necrosis factor inhibitors after treating latent tuberculosis.

Background: Active tuberculosis (TB) risk increases during anti-tumor necrosis factor (TNF) therapy; therefore, latent TB infection (LTBI) screening is recommended in potential TNF inhibitor users. It is unclear whether anti-TNF therapy increases the risk of active TB infection even after standard LTBI treatment.

Objective: The objective of this study was to compare the risk of active TB development in LTBI-positive versus LBTI-negative TNF inhibitor users following the current national LTBI treatment guidelines for LTBI.
