Chronic pain is associated with the development of affective disorders but the underlying mechanisms are not fully understood. Changes in brain centres implicated in both emotional and pain processing are likely to be critical in the interplay of pain control and affective emotional behaviour. In the present study, we assessed emotional behaviour and(More)
Nerve cell injury by unconjugated bilirubin (UCB) has been implicated in brain damage during neonatal hyperbilirubinemia, particularly in the preterm newborn. Recently, it was shown that UCB is a substrate for the multidrug resistance-associated protein 1 (Mrp1), an ATP-dependent efflux pump, which may decrease UCB intracellular levels. To obtain a further(More)
BACKGROUND The pathogenesis of bilirubin encephalopathy and Alzheimer's disease appears to result from accumulation of unconjugated bilirubin (UCB) and amyloid-beta (Abeta) peptide, respectively, which may cause apoptosis. Permeabilization of the mitochondrial membrane, with release of intermembrane proteins, has been strongly implicated in cell death.(More)
Comparative genomic studies of attenuated and virulent strains of Gallid herpesvirus 2 (GaHV-2) have identified 6 regions of sequence variability. These regions include the open reading frames (ORFs) encoding UL36 and UL49 and regions devoid of large ORFs (132-bp repeats, a-like sequences and the junctions flanking the unique short region). Our data(More)
Nanocrystalline diamond (NCD) has a great potential for prosthetic implants coating. Nevertheless, its biocompatibility still has to be better understood. To do so, we employed several materials characterization techniques (SEM, AFM, micro-Raman spectroscopy) and cell culture assays using MG63 osteoblast-like and human bone marrow cells. Biochemical(More)
Microglia are the resident immune cells of the brain and are the principal source of cytokines produced during central nervous system inflammation. We have previously shown that increased levels of unconjugated bilirubin (UCB), which can be detrimental to the central nervous system during neonatal life, induce the secretion of inflammatory cytokines and(More)
Neurogenesis and apoptosis occur contemporaneously in the postnatal hippocampal dentate gyrus and have been implicated in mood and cognitive disorders. Particularly, neurogenesis correlates with the manifestation of antidepressant effects, but its quantitative and topographical relationship with concomitant cell death has not been investigated. Accordingly,(More)
BACKGROUND Synthetic glucocorticoids are commonly prescribed during pregnancy, despite a lack of systematic investigations of their potential impact on the developing brain and neurological and behavioral performance. METHODS Neuroendocrine parameters and behavior in the adult offspring of pregnant Wistar rats treated antenatally with either dexamethasone(More)
A three-phase [nanocrystalline hydroxyapatite (HA), carbon nanotubes (CNT), mixed in a polymeric matrix of polycaprolactone (PCL)] composite scaffold produced by 3D printing is presented. The CNT content varied between 0 and 10 wt % in a 50 wt % PCL matrix, with HA being the balance. With the combination of three well-known materials, these scaffolds aimed(More)
Unconjugated bilirubin (UCB) injury to glial cells leads to the secretion of glutamate and elicits a typical inflammatory response. Release of pro-inflammatory cytokines may influence gliogenesis and neurogenesis, and lead to deficits in learning and memory. Glutamate metabolism dysregulation and overexpression of tumor necrosis factor-α (TNF-α) and(More)
