Hyperuricemia is a known risk factor for chronic kidney disease (CKD) and subsequent renal fibrosis. N6-methyladenosine (m6A) is the most prevalent chemical modification in eukaryotic mRNAs and has been implicated in various diseases. However, its role in hyperuricemic nephropathy (HN) remains unclear.

This article is concerned with the switched control of hybrid terrestrial and aerial quadrotors (HyTAQs) via stochastic hybrid fuzzy system methodology, in which the terrestrial and aerial mode switching is subject to a Markov process with lower-bounded sojourn time. For the first time, the bimodal nonlinear attitude dynamics of HyTAQs is analyzed and modeled based on the Takagi-Sugeno (T-S) fuzzy model, and switched fuzzy controllers are developed to stabilize the hybrid fuzzy system. The characteristic of state dimension switching caused by ground contact is modeled via the singular system presentation with mode-dependent singularity matrices, based on which numerically testable criteria of stability and stabilization in the stochastic sense are derived.

Methods: The expression of peptidase inhibitor 16 (PI16) was analysed using quantitative PCR, immunoblotting and immunohistochemistry assays.
Glioma is the most common malignant primary brain tumor with aggressiveness and poor prognosis. Although extracellular vesicles (EVs)-based cell-to-cell communication mediates glioma progression, the key molecular mediators of this process are still not fully understood. Herein, we elucidated an EVs-mediated transfer of suprabasin (SBSN), leading to the aggressiveness and progression of glioma.

In this study, we evaluate the effect and mechanism of Suprabasin (SBSN) on bladder cancer metastasis.
Methods: A tissue array was used to detect SBSN expression by immunohistochemistry.

Background: Tactile perception is an essential function of skin. As this research involves many fields, such as skin friction, psychology, and neuroscience, the achievement tactile perception is scattered in various fields with different research methods. Therefore, it is necessary to study the whole tactile loop in a multimodal way, synchronizing all tactile information.

Objectives: The aim of this study was to explore the differential expression profiles of microRNAs (miRNAs) in paraffin-embedded acute aortic dissection (AAD) tissues to find potential biomarkers for this disease.
Methods: A total of 92 paraffin-embedded tissue specimens were collected from 92 patients with AAD who underwent surgical replacement. Among these specimens, 54 had partial normal aortic segments (smooth intima surface, non-atherosclerotic lesions) in proximal crevasse of aorta.
Background: Although major driver gene have been identified, the complex molecular heterogeneity of renal cell cancer (RCC) remains unclear. Therefore, more relevant genes need to be identified to explain the pathogenesis of renal cancer.
Methods: Microarray datasets GSE781, GSE6344, GSE53000 and GSE68417 were downloaded from Gene Expression Omnibus (GEO) database.
HER2+ breast cancer (BC) is characterized by rapid growth, early recurrence, early metastasis, and chemoresistance. Trastuzumab is the most effective treatment for HER2+ BC and effectively reduces the risk of recurrence and death of patients. Resistance to trastuzumab results in cancer recurrence and metastasis, leading to poor prognosis of HER2+ BC.

Few studies have investigated the role of HJURP in prostate cancer (PCa). The aim of this study was to analyze the expression levels of HJURP in PCa and to establish the association with clinicopathological data.

Proteasome inhibitors were initially developed as anticancer agents with potential benefits in the suppression of tumor growth. However, clinical trials of patients with solid tumors fail to demonstrate the same efficacy of these proteasome inhibitors.

Subject to cyclic stresses, magnesium alloy stents (MAS) are prone to premature failures caused by corrosion fatigue damage. This work aimed to develop a numerical continuum damage mechanics model, implemented with the finite element method, which can account for the corrosion fatigue of Mg alloys and the applications in coronary stents.
View Article and Find Full Text PDFTo date, more than fifty articles have been published on the feasibility studies of zinc and its alloys as biodegradable metals. These preliminary in vitro and in vivo studies showed acceptable biodegradability and reasonable biocompatibility in bone and blood microenvironments for the experimental Zn-based biodegradable metals and, for some alloy systems, superior mechanical performance over Mg-based biodegradable metals. For instance, the Zn-Li alloys exhibited higher UTS (UTS), and the Zn-Mn alloys exhibited higher elongation (more than 100%).

However, the underlying mechanism by which the NF-κB pathway is constitutively activated in cancer remains largely unclear. The present study aimed to investigate the effect of PICALM interacting mitotic regulator (PIMREG) on sustaining NF-κB activation in breast cancer.

However, the underlying mechanism by which the Wnt/β-catenin pathway is constitutively activated in breast cancer metastasis remains unclear. Inhibition of Wnt antagonists is important for Wnt/β-catenin signaling activation, and post-transcriptional regulation of these antagonists by microRNAs (miRNAs) might be a possible mechanism underlying signaling activation.

Materials And Methods: The mRNA levels of TEF in 408 bladder cancer (BC) samples from the Cancer Genome Atlas (TCGA) database were analysed in depth. Next, the expression of TEF in 7 BC cell lines was compared to that in normal bladder epithelial cells.
Objective: To evaluate the two newly established nomograms for predicting lymph node metastasis in penile cancer based on the clinical data on a large cohort of patients.
Methods: We retrospectively studied the clinical data on 93 patients with penile cancer treated in the Center for Tumor Prevention and Treatment. Using the two recently established nomograms (Bhagat nomogram and Zhu nomogram), we predicted lymph node metastasis in the patients, analyzed the differences between prediction and the results of postoperative pathology, and compared the accuracy of prediction between the two nomograms with the receiver operating characteristic (ROC) curve and the area under the curve (AUC).
