EphrinA5 regulates cell motility by modulating Snhg15/DNA triplex-dependent targeting of DNMT1 to the Ncam1 promoter.

Cell-cell communication is mediated by membrane receptors and their ligands, such as the Eph/ephrin system, orchestrating cell migration during development and in diverse cancer types. Epigenetic mechanisms are key for integrating external "signals", e.g.

Role of DNMTs in the Brain.

DNA methyltransferases (DNMTs) are widely expressed in the brain, dictating the transcriptional activity of genes through various epigenetic mechanisms. Functional irregularities, alterations in the activity, and aberrant expression levels of DNMTs have been linked to various neurodevelopmental abnormalities, neuropsychiatric disorders, neurodegenerative diseases, and brain cancer. A continuously increasing number of studies address the roles DNMTs have in the brain, to reach a better understanding of their involvement in disease-related pathophysiologies, which in turn is required to dissect their applicability as potential therapeutic targets.

The evaluation of intracranial pressure evaluation by optic nerve sheath diameter measurement on bedside ultrasonography after ischemic stroke.

Introduction: We aimed to predict intracranial pressure(ICP)after cerebral ischemic stroke by measuring diameter of the optic nerve sheath(ONSD)with bedside ultrasonography(US). In order to see the ICP changes,it was planned to record delta ICP changes at the 3rd and 5th day follow-up of the patients METHOTS: Patients aged 18 years or older who were admitted to the emergency department(ED)with stroke symptoms for one year were included.Demographic data,time elapsed since the onset of symptoms,neurogical status assesment scales,ONSD values measured by US in three time periods(the day the patient was admitted to the ED,the 3rd and 5th days of hospitalization),MDCT findings when the patient was admitted,ONSD values in MDCT,whether they received tissue plasminogen activator(tPA)and whether they underwent decompression surgery were recorded.

Alterations in inflammatory markers and clinical outcome after spontaneous intracerebral hemorrhage - Preliminary results.

Objective: After an intracerebral hemorrhage, there is an immunological reaction, the specific mechanism of which is not fully understood, that seems to contribute to secondary brain injury. In this study, we investigated alterations of inflammatory markers in the blood and clinical outcome after an intracerebral hemorrhage.

Methods: Between July 2013 and February 2016, we performed a prospective study for which we recruited patients who had suffered an intracerebral hemorrhage.

The reno-protective effects of atorvastatin in crush syndrome and rhabdomyolysis:is there a dilemma?

Background/aim: We aim to determine the effects of low-dose atorvastatin treatment together with crush fluid resuscitation on renal functions and muscle enzyme levels in a rat model of crush syndrome. Materials and methods: The study involved female Wistar Albino rats weighing 250-300 g that were housed with free access to food and water. The crush model was obtained by compression.

Meta-analysis of Statin Use for the Acute Therapy of Spontaneous Intracerebral Hemorrhage.

Background: Growing evidence demonstrates the neuroprotective effects of statins, and the risk to develop an intracerebral hemorrhage (ICH) using statins has been refuted. However, some controversy remains regarding their role in the acute phase after ICH onset. Therefore, we performed a systematic review to investigate this issue.

Radiosensitization of NSCLC cells by EGFR inhibition is the result of an enhanced p53-dependent G1 arrest.

Purpose: How EGF receptor (EGFR) inhibition induces cellular radiosensitization and with that increase in tumor control is still a matter of discussion. Since EGFR predominantly regulates cell cycle and proliferation, we studied whether a G1-arrest caused by EGFR inhibition may contribute to these effects.

Materials And Methods: We analyzed human non-small cell lung cancer (NSCLC) cell lines either wild type (wt) or mutated in p53 (A549, H460, vs.

Spontaneous rupture of intracranial dermoid tumor in a patient with vertigo. Computed tomography and magnetic resonance imaging findings.

Background: Congenital dermoid cysts are very rare, constituting less than 1% of intracranial tumors. Spontaneous rupture of dermoid tumor is a potentially serious complication that can lead to meningitis, seizures, cerebral ischemia and hydrocephalus. Occasionally, dermoid tumors are incidentally discovered on computed tomography (CT) of the brain or magnetic resonance imaging (MRI) following unrelated clinical complaints.

Direct venous spinal reabsorption of cerebrospinal fluid: a new concept with serial magnetic resonance cisternography in rabbits.

Object: For nearly 100 years it has been believed that the main reabsorption of CSF occurs in arachnoid projections into the superior sagittal sinus, but a significant number of experiments and cases conflict with this hypothesis. According to recently published studies, CSF is permanently produced and absorbed in the whole CSF system. Clusters of arachnoidal villi, which are speculated to have a role in the reabsorption of CSF, have recently been revealed in the dorsal root of the spinal nerves.

Language, foreign nationality and ethnicity in an English prison: implications for the quality of health and social research.

Background: More than one in 10 of all prisoners in England and Wales are Foreign Nationals. This article discusses whether the research applications to one London prison are aimed at understanding a prisoner population characterised by significant multinational and multilingual complexity.

Methods: We studied all accessible documents relating to research undertaken at a women's prison between 2005 and 2009 to assess the involvement of Foreign National prisoners and women with limited English.
