Adult spinal axons do not spontaneously regenerate after injury. However, if the peripheral branch of dorsal root ganglion neurons is lesioned before lesioning the central branch of the same neurons in the dorsal column, these central axons will regenerate and, if cultured, are not inhibited from extending neurites by myelin-associated inhibitors of regeneration such as myelin-associated glycop...

This in vitro study was carried out to determine (1) the hydrophobicity of selected oral bacteria, (2) the influence of growth media (saliva and serum) and mode of growth (planktonic or biofilm) on the hydrophobicity of Enterococcus faecalis, and (3) the influence of growth media and conditioning fluids on the adherence of E. faecalis to dentin. The ability to bind to a hydrocarbon phase (xylen...

The recent years brought a growing awareness for the existence of complex neuronal structures within the spinal cord that act as movement controllers. The presented pilot study addresses an extension of pure non-invasive spinal cord stimulation by adding an afferent input from electrically stimulated peripheral nerve. The goal was to assess electrophysiologically the influence of peripheral ner...

BACKGROUND Primary sensory neurons of the dorsal root ganglia (DRG) regenerate their spinal cord axon if the peripheral nerve axon has previously been cut. This conditioning lesion confers axon growth competence to the neurons. However, the signal that is sensed by the cell upon peripheral lesion to initiate the regenerative response remains elusive. RESULTS We show here that loss of electric...

A key finding in studies of the neurobiology of learning memory is that the amygdala is critically involved in Pavlovian fear conditioning. This is well established in delay-cued and contextual fear conditioning; however, surprisingly little is known of the role of the amygdala in trace conditioning. Trace fear conditioning, in which the CS and US are separated in time by a trace interval, requ...

Personal comfort models were developed to circumvent most of the constraints imposed by Predicted Mean Vote ( PMV ) and present adaptive models, which consider average response a large population. Although there has been lot research into new input features for personal spatial data building, such as windows, doors, furniture, walls, fans, heating, ventilation, air conditioning HVAC systems, (t...

Building energy requalification in Italy and Europe has been much discussed recent years due to the high percentage of existing buildings with poor performance. In this context, it is useful obtain a user-friendly fast tool predict thermal demand (TED) for space conditioning related primary consumption (PEC) as function climatic stress. study, SLABE methodology (simulation-based large-scale unc...

We examined the importance of awareness for eyeblink conditioning by directly comparing single-cue delay eyeblink conditioning and single-cue trace eyeblink conditioning. During single-cue delay conditioning, participants who became aware of the stimulus contingencies early in the conditioning session conditioned no better than those who became aware later in the session or did not become aware...
