Ion changes in spreading ischaemia induce rat middle cerebral artery constriction in the absence of NO (2005)

Windmüller, Olaf, Lindauer, Ute, Foddis, Marco, Einhäupl, Karl M., Dirnagl, Ulrich, Heinemann, Uwe, ...

In rats, cortical spreading hyperaemia is coupled to a spreading neuroglial depolarization wave (spreading depression) under physiological conditions, whereas cortical spreading ischaemia is coupled...

Endothelin-1 potently induces Leao's cortical spreading depression in vivo in the rat: A model for an endothelial trigger of migrainous aura? (2002)

Dreier, Jens P., Kleeberg, Jörg, Petzold, Gabor, Priller, Josef, Windmüller, Olaf, Orzechowski, Hans-Dieter, ...

According to the ‘neuronal’ theory, cortical spreading depression (CSD) is the pathophysiological correlate of migrainous aura. However, the ‘vascular’ theory has implicated altered vascular...

Vascular imprints of neuronal activity: Relationships between the dynamics of cortical blood flow, oxygenation, and volume changes following sensory stimulation

Malonek, Dov, Dirnagl, Ulrich, Lindauer, Ute, Yamada, Katsuya, Kanno, Iwao, Grinvald, Amiram

Modern functional neuroimaging methods, such as positron-emission tomography (PET), optical imaging of intrinsic signals, and functional MRI (fMRI) utilize activity-dependent hemodynamic changes to...

ZK200775: A phosphonate quinoxalinedione AMPA antagonist for neuroprotection in stroke and trauma

Turski, Lechoslaw, Huth, Andreas, Sheardown, Malcolm, McDonald, Fiona, Neuhaus, Roland, Schneider, Herbert H., ...

Stroke and head trauma are worldwide public health problems and leading causes of death and disability in humans, yet, no adequate neuroprotective treatment is available for therapy. Glutamate...

Tyrosine Kinase Inhibition Reduces Inflammation in the Acute Stage of Experimental Pneumococcal Meningitis

Angstwurm, Klemens, Hanisch, Uwe-Karsten, Gassemi, Tarraneh, Bille, Margrethe Bastholm, Prinz, Marco, Dirnagl, Ulrich, ...

Bacterial meningitis is an acute inflammatory disease of the central nervous system with a mortality rate of up to 30%. Excessive stimulation of the host immune system by bacterial surface components...

Increased postischemic brain injury in mice deficient in uracil-DNA glycosylase

Endres, Matthias, Biniszkiewicz, Detlev, Sobol, Robert W., Harms, Christoph, Ahmadi, Michael, Lipski, Andreas, ...

Uracil-DNA glycosylase (UNG) is involved in base excision repair of aberrant uracil residues in nuclear and mitochondrial DNA. Ung knockout mice generated by gene targeting are viable, fertile, and...
