Real-Time PCR Quantification of 87 miRNAs from Cerebrospinal Fluid: miRNA Dynamics and Association with Extracellular Vesicles after Severe Traumatic Brain Injury.

Severe traumatic brain injury (sTBI) is an intracranial damage triggered by external force, most commonly due to falls and traffic accidents. The initial brain injury can progress into a secondary injury involving numerous pathophysiological processes. The resulting sTBI dynamics makes the treatment challenging and prompts the improved understanding of underlying intracranial processes.

NEW CONCEPT OF FUSION TECHNICS IN REGIONAL ANESTHESIA.

The aim of this review article is to introduce a newer approach to multimodal anesthesia. In addition to the usual combination of epidural catheter and general anesthesia as standard techniques in surgical procedures accompanied by intense postoperative pain, we want to encourage reflection on the application of various regional techniques in equally complex surgical conditions. By simply modifying the standard neuraxial technique with a higher thoracic approach, excellent abdominal surgery can be performed to awake the patient.

Unveiling the Native Morphology of Extracellular Vesicles from Human Cerebrospinal Fluid by Atomic Force and Cryogenic Electron Microscopy.

Extracellular vesicles (EVs) are membranous structures in biofluids with enormous diagnostic/prognostic potential for application in liquid biopsies. Any such downstream application requires a detailed characterization of EV concentration, size and morphology. This study aimed to observe the native morphology of EVs in human cerebrospinal fluid after traumatic brain injury.

Extracellular Vesicles from Human Cerebrospinal Fluid Are Effectively Separated by Sepharose CL-6B-Comparison of Four Gravity-Flow Size Exclusion Chromatography Methods.

Extracellular vesicles (EVs) are a versatile group of cell-secreted membranous nanoparticles present in body fluids. They have an exceptional diagnostic potential due to their molecular content matching the originating cells and accessibility from body fluids. However, methods for EV isolation are still in development, with size exclusion chromatography (SEC) emerging as a preferred method.
