Multicenter Analysis of Endovascular Aortic Arch In Situ Stent-Graft Fenestrations for Aortic Arch Pathologies

Background: In situ fenestration of aortic stent grafts for treatment of aortic arch aneurysms is a new option for endovascular aortic arch repair. So far, only few reports have shown perioperative and short-term results of in situ fenestrations for aortic arch diseases. We present the multicenter experience with the aortic arch in situ fenestration technique documented in the AARCHIF registry for

Activity evoked by A- and C-afferent fibers in rat dorsal horn neurons and its relation to a flexion reflex

The responses of 56 neurons recorded in the lumbosacral spinal cord of halothane-anesthetized rats were studied following the application of mechanical stimuli to the skin on the lateral aspect of the paw or electrical stimulation of the sural nerve. Only neurons driven by A- and C-fiber stimulation were considered. The evoked activity in a nerve supplying flexor muscles, the common peroneal nerve

Specific functions of grafted locus coeruleus neurons in the kindling model of epilepsy

Grafts of fetal noradrenaline (NA)-rich locus coeruleus (LC) tissue implanted bilaterally into the hippocampus in 6-hydroxydopamine (6-OHDA) treated, hyperexcitable rats retard seizure development in hippocampal kindling. We report that bilateral intrahippocampal LC grafts failed to affect the severity of seizures when implanted in 6-OHDA-treated, already kindled rats. Furthermore, a noradrenergic

Parkinson's disease-like burst firing activity in subthalamic nucleus induced by AAV-α-synuclein is normalized by LRRK2 modulation

Parkinson's disease (PD) affects motor function through degenerative processes and synaptic transmission impairments in the basal ganglia. None of the treatments available delays or stops the progression of the disease. While α-synuclein pathological accumulation represents a hallmark of the disease in its idiopathic form, leucine rich repeat kinase 2 (LRRK2) is genetically associated with familia

Nociceptive inhibition of withdrawal reflex responses increases over time in spinalized rats

Time-dependent changes of nociceptive inhibition of hindlimb withdrawal reflex (WR) pathways were investigated in acute decerebrate spinal rats. Electromyographic recordings of WR of peroneus longus and extensor digitorum longus muscles were made. For each muscle, both short and long latency WR evoked by subcutaneous electrical stimulation and WR evoked by noxious pinch could be inhibited by noxio

Characteristics of postischemic seizures in hyperglycemic rats

Normoglycemic animals subjected to 10-20 min of transient ischemia survive without major neurological symptoms, but incur delayed neuronal damage selectively affecting vulnerable neuronal populations. If the animals are hyperglycemic before ischemia is induced, cell damage develops more rapidly, and postischemic seizures appear after a delay of 18-24 h. This study was designed to assess whether th
