Posterior reversible encephalopathy syndrome (PRES) is characterized by headache, altered mental status, visual disturbances, and seizures. Radiological features typically include edema of the posterior cerebral regions, especially of the parietooccipital lobes. Atypical imaging features, such as involvement of anterior cerebral regions, deep white matter, and the brain stem are also frequently...

Posterior reversible encephalopathy syndrome (PRES) has been defined as a neurological diagnosed with combination of clinical and neuroimaging findings. A 31-year-old female patient no known history the disease was PRES result physical examination imaging. The had other findings than heroin use related naltrexone implant. Although it reported that is caused by various etiological reasons; infor...

BACKGROUND Posterior reversible encephalopathy syndrome (PRES), also called the acute hypertensive encephalopathy and reversible posterior leukoencephalopathy syndrome (RPLS), is a neurotoxic syndrome of cerebral vasoregulation classically characterized by bilaterally symmetrical parieto-occipital edema. However, the imaging findings are variable and may occur in other locations such as the fro...

Polycomb Group (PcG) proteins are epigenetic repressors that control metazoan development and cell differentiation. In Drosophila, PcG proteins form five distinct complexes targeted to genes by Polycomb Response Elements (PREs). Of all PcG complexes PhoRC is the only one that contains a sequence-specific DNA binding subunit (PHO or PHOL), which led to a model that places PhoRC at the base of th...

BACKGROUND AND PURPOSE Hemorrhage is known to occur in posterior reversible encephalopathy syndrome (PRES), but the characteristics have not been analyzed in detail. The purpose of this study was to evaluate the imaging and clinical features of hemorrhage in PRES. MATERIALS AND METHODS Retrospective assessment of 151 patients with PRES was performed, and 23 patients were identified who had in...

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuro-radiological entity may develop in patients with pre-eclampsia, eclampsia or delayed postpartum eclampsia, immunological conditions and with certain anti-neoplastic agents. This case report describes about a patient with pregnancy induced hypertension who developed PRES postnatally. Early recognition and treatment prevented ...

Objectives PRES can occur in HSP infrequently. Here we will review our case, a first reported Korean case, and compare with published cases to find out which symptoms and signs should be aware. Methods First, our case is reviewed retrospectively by electrical medical record. And then, we searched Pubmed database, terms including HSP, PRES, RPLS, and encephalopathy. We compared collected cases a...

A multi-antenna aided base station (BS) supporting several downlink users with the aid of a reconfigurable intelligent surface (RIS) programmable reflecting elements (PREs) is considered. Low-resolution PREs constrained by set sparse discrete values are used for reasons cost-efficiency. Our challenging objective to jointly design beamformers at BS and RIS’s improving throughput all maximizing t...

BACKGROUND Severe haemolysis, elevated liver enzyme levels, and low platelet count (HELLP) syndrome in pregnancy are possible underlying trigger factors for posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging (MRI) shows diffuse signal abnormalities involving the subcortical white matter in the parieto-occipital lobes. Although the diagnosis of RPES was clearly estab...

W.S. Bartynski J.F. Boardman BACKGROUND AND PURPOSE: The cause of posterior reversible encephalopathy syndrome (PRES) is unknown. Two primary hypotheses exist: 1) hypertension exceeding auto-regulatory limits leading to forced hyper-perfusion and 2) vasoconstriction and hypo-perfusion leading to ischemia with resultant edema. The purpose of this study was to evaluate the catheter angiography (C...
