The effects of the dopamine D1 receptor full agonist, A68930, on sleep-wake patterns and grooming behaviour were studied in the rat. The partial dopamine D1 receptor agonist, SKF 38393, was used for comparison. A68930 (0.003-0.3 mg/kg s.c.) increased waking time, reduced the amount of rapid eye movement (REM) sleep and enhanced spontaneous grooming dose(More)
Amyotrophic lateral sclerosis (ALS) is a fatal motoneuronal disease which occurs in sporadic or familial forms, clinically indistinguishable. About 15% of familial ALS cases are linked to mutations of the superoxide dismutase 1 (SOD1) gene that may induce misfolding in the coded protein, exerting neurotoxicity to motoneurons. However, other cell types might(More)
Several types of motorneuron diseases are linked to neurotoxic mutant proteins. These acquire aberrant conformations (misfolding) that trigger deleterious downstream events responsible for neuronal dysfunction and degeneration. The pharmacological removal of misfolded proteins might thus be useful in these diseases. We utilized a peculiar motorneuronal(More)
The dopamine D1 receptor agonist, SKF 38393, and the D1 antagonist, SCH 23390, were studied for their effects on sleep in the rat. Over 6 h, SKF 38393 (0.1-10 mg/kg s.c.) dose dependently reduced the amount of rapid eye movement (REM) sleep and enhanced the duration of wakefulness. The drug affected REM at low doses (ED50 = 0.4 mg/kg) at which wakefulness(More)
A series of antipsychotics having different selectivity for dopamine (DA) D-1 and D-2 receptors were studied for their effects on sleep stages in the rat. Electroencephalographic activity was recorded and classified according to the stages of wakefulness, rapid eye movement (REM) sleep and non-REM sleep. Total sleep duration, non-REM and REM latencies,(More)
Leishmania infantum is a protozoan parasite causing severe vector-borne visceral diseases both in humans and dogs. The latter are the most important natural reservoir and therefore should be the main target of control measures. The real efficacy of seropositive dogs culling as a direct control method is still debated, and the new sensitivity of large part(More)
Jaagsiekte sheep retrovirus (JSRV) is a unique oncogenic virus with distinctive biological properties. JSRV is the only virus causing a naturally occurring lung cancer (ovine pulmonary adenocarcinoma, OPA) and possessing a major structural protein that functions as a dominant oncoprotein. Lung cancer is the major cause of death among cancer patients. OPA(More)
We assessed motor laterality in sheep to explore species-specific brain hemi-field dominance and how this could be affected by genetic or developmental factors. Further, we investigated whether directionality and strength of laterality could be linked to emotional stress in ewes and their lambs during partial separation. Forty-three ewes and their singleton(More)
The clinical benefits of statins are strongly related to their low density lipoprotein-cholesterol (LDL-C) lowering properties. However, because mevalonic acid (MVA), the product of 3-hydroxy-3-methyl-3-glutaryl coenzyme A (HMG-CoA) reductase reaction, is the precursor not only of cholesterol but also of nonsteroidal isoprenoid compounds, the inhibition of(More)
Recent experiments on noncovalent interactions at the nanoscale have challenged the basic assumptions of commonly used particle- or fragment-based models for describing van der Waals (vdW) or dispersion forces. We demonstrate that a qualitatively correct description of the vdW interactions between polarizable nanostructures over a wide range of finite(More)
