Spinal muscular atrophy (SMA) is a genetic disease caused by mutation or deletion of the survival of motor neuron 1 (SMN1) gene. A paralogous gene in humans, SMN2, produces low, insufficient levels of functional SMN protein due to alternative splicing that truncates the transcript. The decreased levels of SMN protein lead to progressive neuromuscular(More)
Excitotoxicity-mediated cell death is involved in Parkinson's disease (PD). 5-HT1A receptor agonists can protect from such mechanisms. The current study demonstrates that the 5-HT1A agonists BAY 639044 and repinotan have neuroprotective effects in a subacute 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD. In addition, we also show(More)
Immunoreactive parathyroid hormone (iPTH) was measured in the serum of 20 patients with early renal failure (ERF) using three assays with different specificity. Half of these patients had elevated iPTH in one or more assays, up to twice the upper limit of normal. In contrast, 36 patients with a creatinine clearance below less than 20 ml/min had an 80%(More)
The pathophysiology of traumatic axonal injury (TAI) is only partially understood. In this study, we investigated the inflammatory response as well as the extent of neurological deficit in a rat model of traumatic brain injury (TBI). Forty-two adult rats were subjected to moderate impact-acceleration brain injury and their brains were analyzed(More)
OBJECTIVE Recent advances in understanding Spinal Muscular Atrophy (SMA) etiopathogenesis prompted development of potent intervention strategies and raised need for sensitive outcome measures capable of assessing disease progression and response to treatment. Several biomarkers have been proposed; nevertheless, no general consensus has been reached on the(More)
Twenty per cent of all strokes are haemorrhagic in character and are associated with severe disturbances in sensorimotor behaviour and cognition. Although spontaneous recovery of pre-stroke functioning occurs in some cases, the process is demanding, slow, and often incomplete. A first step in the preclinical testing of new putative, neuroprotective and(More)
Humans suffering from subdural haematomas often show long-term cognitive dysfunctions. For identifying putative, recovery-enhancing therapeutics, animal models need to be developed in which recovery of function can be measured. For investigating whether and which type of recovery, i.e. spontaneous or training-induced recovery, or continuous partial(More)
Although memory deficits are one of the most persistent consequences of human subdural haematoma, cognitive functioning has hardly been investigated in the rat subdural haematoma model. In the present study, the effects on spatial learning of right- and left-sided unilateral subdural haematoma and of bilateral subdural haematoma induced above the(More)
Single unit recordings from two alert cats were used in an attempt to further elucidate the function of the lateral mesencephalic tegmental region (LTR), a part of the mesencephalon forming a link between the superior colliculus and the lower brain stem. A total of 155 units recorded from the LTR were tested with visual, vestibular and acoustic stimuli. Of(More)
