© 2017 Journal of ophthalmic and Vision research | published by Wolters KluWer medKnoW Dear Editor, In their interesting case report, Ramakrishan et al described a patient with Guillain‐Barre syndrome (GBS) who developed vision loss during the course of the illness and proved later to have posterior reversible encephalopathy syndrome (PRES).[1] Herein, the following two comments regarding that ...

BACKGROUND AND PURPOSE The physiological mechanism that gives rise to posterior reversible encephalopathy syndrome (PRES) is currently unknown. We sought to better understand the mechanism of the edema formation in PRES and specifically hypothesized that this edema is caused by increased vascular permeability. METHODS Eight consecutive patients with PRES who had been studied by using perfusio...

Polycomb group response elements (PREs) in Drosophila are DNA-elements that recruit Polycomb proteins (PcG) to chromatin and regulate gene expression. PREs are easily recognizable in the Drosophila genome as strong peaks of PcG-protein binding over discrete DNA fragments; many small but statistically significant PcG peaks are also observed in PcG domains. Surprisingly, in vivo deletion of the f...

Objective Posterior reversible encephalopathy syndrome (PRES) is characterized by typical radiologic findings in the posterior regions of the cerebral hemispheres and cerebellum. The symptoms include headache, nausea, vomiting, visual disturbances, focal neurologic deficits, and seizures. The aim of this study is to evaluate the clinical and radiological features of PRES in children and to emph...

BACKGROUND Posterior reversible encephalopathy syndrome (PRES) has been associated with Guillain-Barre syndrome in rare cases. Here we report a patient in whom PRES was the presenting manifestation of Bickerstaff's brainstem encephalitis. CASE PRESENTATION A 75-year-old woman presented with acute onset of hypertension, headache, blurred vision, and left eyelid drooping. Magnetic resonance ima...

Polycomb group (PcG) and trithorax Group (trxG) proteins maintain the "OFF" and "ON" transcriptional states of HOX genes and other targets by modulation of chromatin structure. In Drosophila, PcG proteins are bound to DNA fragments called Polycomb group response elements (PREs). The prevalent model holds that PcG proteins bind PREs only in cells where the target gene is "OFF". Another model pos...

cis-Regulatory DNA elements contain multiple binding sites for activators and repressors of transcription. Among these elements are enhancers, which establish gene expression states, and Polycomb/Trithorax response elements (PREs), which take over from enhancers and maintain transcription states of several hundred developmentally important genes. PREs are essential to the correct identities of ...

BACKGROUND Adult patients with cancer receiving antineoplastic, targeted, and other immunosuppressive therapies are at risk for severe side effects. Studies link posterior reversible encephalopathy syndrome (PRES) with immunosuppressants used for patients undergoing transplantation, as well as select tyrosine kinase inhibitors (TKIs) and other targeted therapies used in patients with cancer. PR...

Hyperperfusion syndrome, previously known as posterior reversible encephalopathy syndrome (PRES), is a clinico- radiological entity with characteristic features on neuro-imaging. It is believed to be caused by vasogenic oedema, predominantly in the posterior cerebral hemispheres. We report the case of an elderly man who presented with convulsions and was diagnosed to have PRES due to hypertension.

Toman fish is a pure carnivore which so far has used wild catches as its entire diet. Alternative feed with high animal protein and easy to obtain needs be done. Fermentation activities using tempe yeast can usually increase the content of material. Studies on use fermented maggot for toman seed have not yet obtained sufficient information, in-depth research this matter really This study aims a...
