Article Abstract
Recent evidence has suggested that competitive endogenous RNAs (ceRNAs) are important regulatory molecules in clear cell kidney carcinoma (KIRC) and their dysregulation may contribute to cancer pathogenesis. However, the critical roles of dysregulated ceRNAs in KIRC remain unknown. In the present study, a KIRC dysregulated ceRNA‑ceRNA network (KDCCNet) was constructed based on the 'ceRNA hypothesis' by integrating microRNA regulation and expression profiles in cancerous and normal tissues. Two dysregulated patterns of ceRNAs interaction (gain and loss) exist in KDCCNet. The two modules, which are 95% loss interactions and 97% gain interactions, were demonstrated to be able to distinguish normal samples from cancer samples. Two long non‑coding (lnc)‑RNAs (glucuronidase β pseudogene 11 and LIFR antisense RNA 1) demonstrated significant associations with KIRC prognosis. The present study of the KDCCNet revealed a novel biological mechanism for KIRC and provides novel lncRNAs as candidate prognostic biomarkers.

Background: The cerebral circulation is continuously challenged by intravascular micrometer-sized particles that become trapped microvascular-emboli. These particles may include micro-thrombi, stiffened erythrocytes, and leukocytes, while also fat particles, air, and microplastics may cause microvascular embolism.
Review Scope: In this narrative review, we discuss these embolization processes and their acute and chronic consequences.

Although the surface micro-ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub-spectacular space. The surface ultrastructure of the "Oberhäutchen" of the spectacle is examined in nine species of snakes (five aquatic and four terrestrial) using light and electron microscopy, micro-computed tomography and gel-based profilometry. Significant topographic differences in cell size (increases of between 5.

The effect of non-functionalized polystyrene nanoparticles (PS-NPs) with diameters of 29, 44, and 72 nm on plasmid DNA integrity and the expression of genes involved in the architecture of chromatin was investigated in human peripheral blood mononuclear cells (PBMCs). The cells were incubated with PS-NPs at concentrations ranging from 0.001 to 100 µg/mL for 24 hours.

Introduction: von Hippel-Lindau (VHL) disease is an autosomal dominant hereditary disorder characterized by the development of tumor-like lesions in multiple organs. While central nervous system hemangioblastomas, pancreatic neuroendocrine tumors, and pancreatic cysts are commonly associated with VHL disease, there have been few reported cases of pancreatic hemangioblastoma in patients with VHL disease.
Case Presentation: A male patient in his 30s had been diagnosed with VHL disease and had been followed for cerebellar and spinal hemangioblastomas, and renal cell carcinoma, for which he had undergone several tumor resections, radiation therapy, and a ventriculoperitoneal shunt.

Hepatocellular carcinoma (HCC) is a prevalent malignant neoplasm of the digestive system, including 80% of primary liver malignancies. The Wnt/β-catenin signaling pathway plays a key role in immune response and tumer resistance. A growing number of studies have shown that the Wnt/β-catenin signaling pathway is involved in the pathogenesis of HCC.
