Investigation of the hydrodynamic properties of a new MRI-resistant programmable hydrocephalus shunt

Cerebrospinal Fluid Research, 2008
Background The Polaris valve is a newly released hydrocephalus shunt that is designed to drain cerebrospinal fluid (CSF) from the brain ventricles or lumbar CSF space.

Lumbar-peritoneal shunt for idiopathic normal pressure hydrocephalus and secondary normal pressure hydrocephalus

Tzu Chi Medical Journal, 2022
Objectives: Normal-pressure hydrocephalus is a clinical syndrome consisting of dilated cerebral ventricles with the clinical triad of gait disturbance, cognitive impairment and/or urinary dysfunction. Lumbar-peritoneal (LP) shunt could improve idiopathic

Leakage Inductance Calculation for Planar Transformers With a Magnetic Shunt [PDF]

IEEE Transactions on Industry Applications, 2013
The magnetic shunt is generally inserted in a planar transformer to increase the leakage inductance, which can be utilized as the series inductor in resonant circuits such as the LLC resonant converter. This paper presents a calculation methodology for the leakage inductance of the transformer with a magnetic shunt by means of the stored magnetic ...

Health disparities in chronic liver disease

Hepatology, EarlyView., 2022
Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.

Communicating hydrocephalus due to cerebral venous sinus thrombosis treated with ventriculoperitoneal shunt

Annals of Indian Academy of Neurology, 2012
Cerebral venous sinus thrombosis (CVT) is a rare cerebrovascular disease with variable presentation. CVT rarely causes hydrocephalus. Communicating hydrocephalus due to CVT is extremely rare.

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis

Hepatology, EarlyView., 2022
Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Non-invasive assessment of pulsatile intracranial pressure with phase-contrast magnetic resonance imaging. [PDF]

PLoS ONE, 2017
Invasive monitoring of pulsatile intracranial pressure can accurately predict shunt response in patients with idiopathic normal pressure hydrocephalus, but may potentially cause complications such as bleeding and infection.

Resistance in Superconductors [PDF]

, 2010
In this pedagogical review, we discuss how electrical resistance can arise in superconductors. Starting with the idea of the superconducting order parameter as a condensate wave function, we introduce vortices as topological excitations with quantized ...

Treatment of Posttubercular Syringomyelia Not Responsive to Antitubercular Therapy: Case Report and Review of Literature

Journal of Neurological Surgery Reports, 2017
Posttubercular adhesive arachnoiditis is a rare, late complication of tubercular meningitis. Syringomyelia can develop as a consequence of intramedullary cystic lesions and cerebrospinal fluid (CSF) flow disturbance around the spinal cord, even after ...
