Article Abstract
Introduction: The successful introduction of immune checkpoint blockade approaches to renal-cell carcinoma (RCC) treatment indicates the importance of molecules regulating the T cell response to RCC risk and progression.
Material And Methods: In this study, we evaluate the association of variations in the , and genes with overall survival (OS) of RCC patients and specifically clear cell RCC (ccRCC) patients. The following single nucleotide polymorphisms (SNPs) previously genotyped using the RFLP method or TaqMan SNP Genotyping Assays were analyzed: gene: c.49A>G (rs231775), g.319C>T (rs5742909), g.*6230G>A (CT60; rs3087243), g.*10223G>T (Jo31; rs11571302); gene: c.17+3T>C (rs3116496), c.-1042G>A (rs3181098); gene: rs2705511, rs1982809, rs9288952, rs9288953, rs2705535 and rs1844089.
Results: During long term observation (6.5 years) we discovered that possessing the A allele at BTLA rs1844089 SNP, together with advanced disease (stage ≥ 3, tumor grade > 3, tumor diameter ≥ 70 mm), is an independent risk factor of death which increases the hazard ratio (HR) of death by more than two-fold (HR = 2.21, 95% CI: 1.28-3.83). Furthermore, the OS of patients bearing this allele is 6 months shorter than for homozygous (GG) patients (42.5 vs. 48.2 months).
Conclusions: Our results indicate for the first time that genetic variation within the gene encoding BTLA is significantly associated with overall survival in clear cell renal cell carcinoma patients.

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.
