SpineTo assess the degree of fluid–fluid levels on MRI in spinal tumours compared with final diagnosis, and the outcome of needle biopsy in such cases.Retrospective review of patients with a spinal tumour that contained fluid–fluid levels. Data collected included age, sex, spinal location, and...
These structures are described as a series of tubules within an outgrowth of arachnoid tissue that are continuous with the CSF of the SAS of the cranium and the spine8,9. They were initially believed to act as one-way valves for a pressure-driven flow from CSF to venous blood10; however...
Neurogranin (Ng) is a neuron-specific and postsynaptic protein that is abundantly expressed in the brain, particularly in the dendritic spine of the hippocampus and cerebral cortex. The enzymatic cleavage of Ng produces fragments that are released into cerebrospinal (CSF), which have been shown to...
SETTING Eight tertiary obstetric units, from NHS hospitals. PATIENTS Parturients with accidental dural puncture (ADP) underwent T1 and T2-weighted MRI scans of the brain and lumbar spine within 48?h after delivery. All women were followed up, daily, for 1 week. MAIN OUTCOME MEASURES For ...
PDPH in obstetric patients.DESIGN\nA prospective double-blind quasi-observational study.SETTING\nEight tertiary obstetric units, from NHS hospitals.PATIENTS\nParturients with accidental dural puncture (ADP) underwent T1 and T2-weighted MRI scans of the brain and lumbar spine within 48h after...
literature between paediatric medicine and geriatric medicine, Cerebrospinal Fluid Disorders examines the disorders of the cerebrospinal fluid (CFS) pathways from birth to old age, exploring and managing the resultant effects of such disorders on both the brain and spine throughout the changes in ...
This study aims to evaluate the application of Liqoseal in transsphenoidal surgery ex vivo and in vivo. Methods 1. We created an ex vivo setup simulating the sphenoidal anatomy, using a fluid pump and porcine dura positioned on a conus with the anatomical dimensions of the sella ...
Moreover, an effect of the “rostro-caudal gradient”, i.e., the distance between the ventricles and the lumbar subarachnoid space, where the protein content seems to increase, has been hypothesised [41]. The hypothesis that sex differences in body height, resulting in a greater spine length...
Such representation is indirectly based on the assumption that the streamlines of a hypothetical creeping flow are perpendicular to the said plane because its tangent components are taken as the Dean flow components. Reference cross-sectional planes (based on the geometry of the channel) to ...
The on-site use of quasi-dry fracturing showed that optimizing the mixing ratio of liquid CO2 fracturing fluid and ZJL-1 fracturing fluid effectively enhanced oil and gas recovery. This can be used to optimize quasi-dry fracturing and can be used as a reference. Citation: Hu, J.; Fu, M...
