Parry-Romberg syndrome (PRS) is a variant of morphea usually characterized by a slowly progressive course. Clinical and radiological involvement of the central nervous system may be observed in PRS. We describe 2 patients with PRS and neurological symptoms (one with trigeminal neuralgia associated with deafness, and the second with hemifacial pain associated with migraine without aura) in conju...

The task of the visual system is to translate light into neuronal encoded information. This translation of photons into neuronal signals is achieved by photoreceptor neurons (PRs), specialized sensory neurons, located in the eye. Upon perception of light the PRs will send a signal to target neurons, which represent a first station of visual processing. Increasing complexity of visual processing...

Steroid hormone, progesterone, modulates neuroendocrine functions in the central nervous system resulting in alterations in physiology and behavior. These neuronal effects are mediated primarily by intracellular progestin receptors (PRs) in the steroid-sensitive neurons, resulting in transcription-dependent genomic actions (classical mechanism). In addition to progesterone, intracellular PRs ca...

Interactions between the medial entorhinal cortex (MEC), presubiculum (PrS), and parasubiculum (PaS), all essential components of the hippocampalparahippocampal navigational system, are still poorly understood. The PrS and PaS are credited to provide directional information to MEC. Efferents from PrS and PaS show a laminar specific terminal distribution in MEC superficial layers, where they als...

BACKGROUND Previous surveys on the relationship between physicians and pharmaceutical representatives (PRs) have been of limited quality. The purpose of our survey of practicing physicians in Japan was to assess the extent of their involvement in pharmaceutical promotional activities, physician characteristics that predict such involvement, attitudes toward relationships with PRs, correlations ...

Give me but a firm spot on which to stand, and I shall move the earth. and I set sail on a new adventure with the launch of Plastic and Reconstructive Surgery—Global Open (PRS Global Open). 1 It was a voyage into unknown territory for some of us: PRS Global Open was one of the first open-access surgery journals in the world, and the first new academic journal for ASPS in more than half a centur...

The pain relief scale (PRS) is a method that measures the magnitude of change in pain intensity after treatment. The present study aimed to evaluate the correlation between PRS and changes in pain determined by the visual analogue scale (VAS) and numerical rating scale (NRS), to confirm the evidence supporting the use of PRS. Sixty patients with chronic spinal pain that had a VAS and NRS record...

Dear Sir, Instead of a relative mean citation rate, a percentile rank score (PRS) can be used in bibliometrics to generate a normalized citation impact for a paper. The use of a PRS is very advantageous, as no assumptions have to be made as to the distribution of citations in the reference set; that is, the scores are applicable also for the (usually) rightskewed distributions. To calculate the...

We recently characterized physiologically a pontine reticulospinal (pRS) projection in the neonatal mouse that mediates synaptic effects on spinal motoneurons via parallel uncrossed and crossed pathways (Sivertsen et al. [2014] J Neurophysiol 112:1628-1643). Here we characterize the origins, anatomical organization, and supraspinal axon trajectories of these pathways via retrograde tracing from...

Background: The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance.Objective: In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD.Method: T...
