BACKGROUND: Mechanisms involved in brain changes observed in major depression have been poorly investigated in clinical populations. Changes in cerebral blood flow (CBF) have been found in depressed patients and constitute a potential mechanism by which brain volume varies in depression. We have tested the association of cerebral blood flow velocity (CBFV) as assessed with Transcranial Doppler (TCD) and cerebral blood flow (CBF) as assessed with Arterial Spin Labeling Magnetic Resonance Imaging (ASL-MRI) with Total Brain Volume (TBV) and the volume of seven subcortical regions, in currently depressed and long-term remitted patients...

PURPOSE: Propofol is a short-acting medication with fast cognitive and psychomotor recovery. However, patients are usually instructed not to drive a motor vehicle for 24 hours after receiving propofol. The purpose of this article was to review the evidence examining when it is safe to drive after receiving propofol for sedation for diagnostic and surgical procedures. DESIGN: This is a systematic review of the literature. METHODS: A search of the literature was conducted using Google Scholar, PubMed, and the Cochrane Library for the time period 1990 to 2015...

The focused set of new pyrrolidine-2,5-diones as potential broad-spectrum hybrid anticonvulsants was described. These derivatives integrate on the common structural scaffold the chemical fragments of well-known antiepileptic drugs such as ethosuximide, levetiracetam, and lacosamide. Such hybrids demonstrated effectiveness in two of the most widely used animal seizure models, namely, the maximal electroshock (MES) test and the psychomotor 6 Hz (32 mA) seizure model. Compound 33 showed the highest anticonvulsant activity in these models (ED50 MES = 79...

The neural responses during hyperthermia, once thought of as simple physiological processes (e.g. thermal sensation and regulation), have now been recognized involving more cognitive processes, which would be highly of importance to the management of those occupations during heavy heat exposure. Previous studies have demonstrated altered activity in localized subcortical clusters for thermal sensation and regulation, as well as cortical-cortical activity for behavioral tasks during hyperthermia. However, the involvement of cortical-subcortical activity during hyperthermia has not been investigated...

The clinical education of paramedic students is an international concern. In Australia, student placements are commonly undertaken with local district ambulance services, however these placements are increasingly limited. Clinical placements within inter-professional settings represent an innovative yet underdeveloped area of investigation. This paper addresses that gap by reporting a pilot evaluation of paramedic student clinical placements in a specialised obstetrics setting. Using a case study approach, the evaluation aimed to identify paramedic psychomotor skills that could be practised in this setting, and understand the nature of key learning events...

Mutations in MECP2 cause Rett syndrome (RTT), an X-linked neurological disorder characterized by regressive loss of neurodevelopmental milestones and acquired psychomotor deficits. However, the cellular heterogeneity of the brain impedes an understanding of how MECP2 mutations contribute to RTT. Here we developed a Cre-inducible method for cell-type-specific biotin tagging of MeCP2 in mice. Combining this approach with an allelic series of knock-in mice carrying frequent RTT-associated mutations (encoding T158M and R106W) enabled the selective profiling of RTT-associated nuclear transcriptomes in excitatory and inhibitory cortical neurons...
