Positron emission tomography (PET) imaging of P-glycoprotein (P-gp) in the blood-brain barrier can be important in neurological diseases where P-gp is affected, such as Alzheimer´s disease. Radiotracers used in the imaging studies are present at very small, nanomolar, concentration, whereas in vitro assays where these tracers are characterized, are usually performed at micromolar concentration, causing often discrepant in vivo and in vitro data. We had in vivo rodent PET data of [(11)C]verapamil, (R)-N-[(18)F]fluoroethylverapamil, (R)-O-[(18)F]fluoroethyl-norverapamil, [(18)F]MC225 and [(18)F]MC224 and we included also two new molecules [(18)F]MC198 and [(18)F]KE64 in this study...

 Extensive exposure of boxers to neurotrauma in the early 20th century led to the so-called punch drunk syndrome, which was formally recognized in the medical literature in 1928. "Punch drunk" terminology was replaced by the less derisive 'dementia pugilistica' in 1937. In the early case material, the diagnosis of dementia pugilistica required neurological deficits, including slurring dysarthria, ataxia, pyramidal signs, extrapyramidal signs, memory impairment, and personality changes, although the specific clinical substrate has assumed lesser importance in recent years with a shift in focus on molecular pathogenesis...

Fluctuating hearing loss and vertigo are the typical presentations of Meniere's disease. However, it is unusual that fluctuating hearing loss and vertigo are caused by vertebral artery occlusion or cerebral infarction. Here, we described the case of a 54-year-old male patient with hypertension and diabetes mellitus who presented with fluctuating hearing loss in his left ear and severe whirling-type dizziness without associated neurological signs or symptoms. Temporal magnetic resonance imaging (MRI) was normal...

Aims: Delay in administration of epinephrine is associated with decreased survival among children with in-hospital cardiac arrest with an initial non-shockable rhythm. Whether this association is applicable to paediatric out-of-hospital cardiac arrest (OHCA) population remains unknown. We aimed to determine whether time to epinephrine administration is associated with outcomes in paediatric OHCA. Methods and results: This was a nation-wide population-based study of paediatric OHCA in Japan from 2005 to 2012 based on data from the All-Japan Utstein Registry...

The calcium-binding protein calbindin-D28k is critical for hippocampal function and cognition, but its expression is markedly decreased in various neurological disorders associated with epileptiform activity and seizures. In Alzheimer's disease (AD) and epilepsy, both of which are accompanied by recurrent seizures, the severity of cognitive deficits reflects the degree of calbindin reduction in the hippocampal dentate gyrus (DG). However, despite the importance of calbindin in both neuronal physiology and pathology, the regulatory mechanisms that control its expression in the hippocampus are poorly understood...

Multiple sclerosis is one of the most common neurological diseases in young people. This paper dealt with an automatic biomedical aided tool involving volumetric segmentation of Multiple Sclerosis lesions. To meet this challenge, our proposed methodology requires one preliminary cerebral zones segmentation performed using a new Gaussian Mixture Model based on various databases atlases. Afterwards, lesion segmentation begins with the estimation of a lesion map which is then subjected to threshold constraints and refined by a new lesion expansion algorithm...

Clinical gene therapy has made important advances over the last decade. Among neurological diseases, severe genetic neurodegenerative conditions have been the focus of initial clinical applications. Gene therapy has also addressed complex neurodegenerative diseases, particularly Parkinson's disease, with encouraging results in human patients, demonstrating that specific targeting of central nervous system (CNS) cells is a relevant strategy for severe pathologies and that efficient access to the CNS with viral vectors is an achievable goal...

Although neural stem cells (NSCs) have potential applications in treating neurological disorders, much still needs to be understood about the differentiation biology for their successful clinical translation. In this study, we aimed at deriving NSCs from human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) and explored the role of Notch signaling in the differentiation process. The hUCB-MSCs were characterized as per guidelines of the International Society of Cellular Therapy. NSCs were successfully generated from hUCB-MSCs by using epidermal and fibroblast growth factors under serum-free conditions...

Charcot-Marie-Tooth disease (CMT1B) is an inherited neurological disorder caused by mutation of the myelin protein zero (MPZ) gene. We generated an induced pluripotent stem cell (iPSC) line from an 81-year-old patient with CMT1B by electroporating of lymphoblastoid cell lines with episomal plasmids encoding OCT4, SOX2, KLF4, L-MYC, LIN28, and p53-targeting shRNA. The established iPSCs expressed various pluripotency markers, demonstrated the potential to differentiate into cells of the three germ layers in vitro, had a normal karyotype and retained the MPZ mutation...

BACKGROUND: As the quest to eradicate malaria continues, there remains a need to gain further understanding of the disease, particularly with regard to pathogenesis. This is facilitated, apart from in vitro and clinical studies, mainly via in vivo mouse model studies. However, there are few studies that have used gerbils (Meriones unguiculatus) as animal models. Thus, this study is aimed at characterizing the effects of Plasmodium berghei ANKA (PbA) infection in gerbils, as well as the underlying pathogenesis...
