NRU moves to the new North Wing in 2019

Details: Published: Monday, 19 June 2017 09:09; Hits: 1639

NRU, including laboratories, will jointly move to the North Wing Phase II in brand-new facilities. This means that the research unit can be housed together again which will be a great benefit. The move is anticipated to take place Spring 2019, once the construction has been completed.

Scholarship grant from FSS to NRU

Gitte Moos and Sebastian Holst have received a scholarship grant (103.000) from FSS for the project: 'Effects of sleep deprivation and adrenergic inhibition on glymphatic flow in humans'.

Short project summary:
Roughly a third of our life is spent asleep, yet the function(s) of sleep remain poorly understood. Recently, a novel molecular role for sleep was described in rodents. The ‘glymphatic system’ is a sleep dependent macroscopic pathway in the brain, which facilitates clearance of interstitial waste products. So far, the glymphatic system has only been described in rodents. Here, effects of the human glymphatic system will be investigated in two ways. First, we will apply the novel
MR protocol MREG (ultra-fast magnetic resonance encephalography) in both awake and sleeping subjects to show the existence of human glymphatic flow. Secondly, we will interfere with glymphatic flow by administering the adrenergic antagonist carvedilol in a placebo controlled, crossover manner immediately before MREG imaging. Thereby we will test the effects of enhanced glymphatic activity on sleep and wakefulness. Together the study will provide the first evidence for a sleep dependent human glymphatic system.

Congratulations to Vibe Frøkjær and Lars Pinborg, each for receiving 1.8 mio for the projects 'The role of sex steroids and serotonin brain dynamics in perinatal mental health' and 'Severe epilepsy - a new era in the presurgical evaluation by ultra high field MR at 7 Tesla', granted by the Danish Council for Independent Research - Medical Sciences.

Short Danish summaries:
Depression er en folkesygdom med enorme personlige og samfundsmæssige omkostninger. Sygdommen rammer dobbelt så mange kvinder som mænd, og der er et påtrængende behov for at målrette og optimere forebyggelse og behandling. Risikoen for at udvikle depression er markant forhøjet hos kvinder, når de i forbindelse med graviditet og fødsel gennemgår store kønshormonelle svingninger. Vi ved ikke, hvorfor nogle kvinder er i særlig risiko for fødselsdepression, men nye studier peger på, at østrogenfølsomhed spiller en afgørende rolle. Vi har tidligere påvist, at farmakologisk udløste ændringer i kvindeligt kønshormon kan udløse milde depressive symptomer hos ellers raske kvinder. Symptomerne er koblet både til østrogenudsving og til en stigning i hjernens serotonin transporter (SERT) niveau, der sænker hjernens signalstof serotonin. Vi ved dog ikke, om graviditet er forbundet med en stigning af SERT, som i en overgangsfase vil sænke hjernens serotoninniveau. Vi vil i dette projekt undersøge kvinder under graviditet, ved fødslen og i det tidlige efterfødselsforløb for at afdække samspillet mellem kønshormoner, serotonin og depression. Vi vil også teste, om en biomarkør kandidat (gentranskriptionsprofil) forudsiger fødselsdepression og serotonerg tonus lige så godt som hjerneskan 4 uger efter fødslen. Vores mål er at finde biomarkører, der kan identificere kvinder i højrisiko for fødselsdepression for derved at kunne målrette en individualiseret forebyggelse.
---------------------
Ultra højfelts magnetisk resonans (MR) skanning ved 7 tesla (7T MR) vil blive anvendt til udforskning af svær epilepsi, idet 7T MR giver flere og mere detaljerede oplysninger om strukturelle og biokemiske forhold i hjernen end den konventionelle MR skanning ved 3T. Vores arbejdshypotese er, at 7T MR skanning vil give ny viden om epilepsisygdommens natur, om strukturelle og biokemiske abnormiteter samt om epileptiske netværk. De opnåede resultater forventes at få direkte betydning for den preoperative udredning forud for epilepsikirurgiske indgreb. Placeringen af intrakranielle elektroder anbragt på og i hjernen vil kunne forgå mere præcist og i nogle tilfælde helt kunne undgås. Den forbedrede preoperative udredning vil føre til bedre kirurgiske resultater, dvs. flere patienter vil kunne tilbydes operation, og flere vil kunne gøres anfaldsfri. Vi har allerede foreløbige resultater, der viser forbedret diagnostisk værdi af 7T MR, hvilket understøtter arbejdshypotesen.

NRU in the media about the mysterious epilepsy

Ass. Prof Lars Pinborg and Prof Gitte Moos Knudsen participated in the third episode of DR K’s documentary “Død og pine: Lægevidenskabens Historie” which was about the history of medicine and the development within epilepsy treatment and brain imaging. The episode was broadcasted March 1, 2017, but can be seen here: https://www.dr.dk/tv/se/doed-og-pine/-/doed-og-pine-laegevidenskabens-historie-3#!

PhD student Mette Thrane Foged has in a small video clip explained about new studies with a recently developed and refined EEG cap, which with an unprecedented precision can show where in the human brain the epilepsy occurs. Information which is highly relevant for doctors when deciding whether or not a given epilepsy patient should be offered a surgical procedure.

Congratulations to Gitte for receiving 100.000 DKK from Brødrene Hartmanns Fond for the NeuroPharm (NP2) project "Neurobiologiske effekter af 5-HT2AR modulering". The grant will finance a new fluorescence detector for NRU which in this project will be used for measuring ketanserin levels in plasma. Below is a Danish summary of the granted application.
