Abstract Purpose: Carbonic anhydrase IX (CA IX) is a hypoxia-inducible enzyme, which associated with neoplastic growth. Ectopic CA expression has been observed in several tumors, whose normal counterparts do not express this enzyme. Normal human brain tissue shows only slight or no of IX. Experimental Design: We describe diffusely infiltrating astrocytomas. The association evaluated clinicopathologic and molecular factors including cell proliferation apoptosis as well the p53 epidermal...
Deep brain stimulation (DBS) is a minimally invasive and reversible method to treat an increasing number of neurological psychiatric disorders, including epilepsy. Targeting poorly defined deep structures based in large degree on stereotactic atlas information, which may be major source inconsistent treatment effects.

More importantly, these biofluids contain biomarkers similar those in blood. Therefore, developing sensors for noninvasive determination biofluid‐based overcome traditionally...
Carbonic anhydrase XII (CA XII) is a transmembrane enzyme that associated with neoplastic growth. CA has been proposed to be involved in acidification of the extracellular milieu, creating an appropriate microenvironment for rapid tumor Because RNA sequence databases have indicated two isoforms might exist human tissues, and because alternatively spliced protein forms linked aggressive behavior cancer cells, we designed study evaluate presence diffuse astrocytomas, type known its often...
Abstract Background Defective iron homeostasis may be involved in the development of some diseases within central nervous system. Although expression genes normal balance has been intensively studied other tissues, little is known about their brain. We investigated mRNA levels hepcidin ( HAMP ), HFE, neogenin NEO1 transferrin receptor 1 TFRC 2 TFR2 and hemojuvelin HFE2 ) human brain, brain tumors, astrocytoma cell lines. The specimens included 5 tissue samples, 4 meningiomas, one...
Medulloblastomas (MBs) and supratentorial primitive neuroectodermal tumours (PNETs) are the most common highly aggressive paediatric brain tumours. In spite of extensive research on these tumours, there only few known biomarkers or therapeutic target proteins, prognosis patients with remains poor. Our aim was to investigate whether carbonic anhydrases (CAs), enzymes commonly overexpressed in various including glioblastomas oligodendrogliomas, present MBs PNETs, their expression can be...
Abstract The tumor immune microenvironment (TiME) of human central nervous system (CNS) tumors remains to be comprehensively deciphered. Here, we employed flow cytometry and RNA sequencing analysis for a deep data-driven dissection diverse TiME uncover noncanonical cell types in CNS by using seven from five patients. Myeloid subsets comprised classical microglia, monocyte-derived macrophages, neutrophils, two myeloid subsets: CD3 + myeloids CD19 myeloids. T lymphocyte included...
A substantial proportion of patients undergoing surgery for chronic subdural hematoma (CSDH) use anticoagulation medication due to atrial fibrillation (AF).
