BACKGROUND: The Bernese Pain Scale for Neonates (BPSN) is a multidimensional pain assessment tool that is already widely used in clinical settings in the German speaking areas of Europe. Recent findings indicate that pain responses in preterm neonates are influenced by individual contextual factors, such as gestational age (GA), gender and the number of painful procedures experienced. Currently, the BPSN does not consider individual contextual factors. Therefore, the aim of this study is the validation of the BPSN using a large sample of neonates with different GAs...

The stator-complex in the bacterial flagellar motor is responsible for surface-sensing. It remodels in response to perturbations in viscous loads, recruiting additional stator-units as the load increases. Here, we tested a hypothesis that the amount of torque generated by each stator-unit modulates its association with the rotor. To do this, we measured stator-binding to the rotor in mutants in which motors reportedly develop lower torque compared to wildtype motors. First, we employed a strain lacking fliL...

An 89-year-old man attempted suicide by ingesting a pesticide (trichlorfon). After surviving the initial critical period in the intensive care unit, he developed rapidly progressive distal weakness and sensory disturbance. Electrophysiological examinations revealed sensory motor axonal polyneuropathy. Delayed polyneuropathy is a rare manifestation of organophosphate poisoning. Nerve conduction studies play an important role in the diagnosis of this rare clinical condition.

Functional neuroimaging studies have led to understanding the brain as a collection of spatially segregated functional networks. It is thought that each of these networks is in turn composed of a set of distinct sub-regions that together support each network's function. Considering the sub-regions to be an essential part of the brain's functional architecture, several strategies have been put forward that aim at identifying the functional sub-units of the brain by means of functional parcellations. Current parcellation strategies typically employ a bottom-up strategy, creating a parcellation by clustering smaller units...

OBJECTIVES: Previous research on gastrointestinal and other medical conditions has shown the presence of incongruence between self- and clinician-reported functioning and its relation with psychopathology. The main objective of this study was to test whether inconsistencies between clinician- and self-assessed functionality can be used to detect psychopathology among patients diagnosed of motor or functional gastrointestinal disorders. METHODS: One hundred and three patients from a gastroenterology inpatient unit were included in this study...

REVIEW
Mohammed M Al-Qattan
The classic donor motor units for opponensplasty are the flexor digitorum superficialis, the extensor indicis proprius, the palmaris longus, and the abductor digiti minimi. Occasionally, all classic donor motor units are not available for the opponensplasty; a review of the literature revealed that the flexor carpi ulnaris opponensplasty has not been previously described. The surgical technique of the split flexor carpi ulnaris opponensplasty is described in the current paper along with a clinical example...

OBJECTIVE: The clinical outcome of Parkinson's disease (PD) patients that undergo Subthalamic Nucleus Deep Brain Stimulation (STN DBS) is, in part, determined by the length of the electrode trajectory through the motor STN domain, the Dorso-Lateral Oscillatory Region (DLOR). Trajectory length has been found to correlate with the stimulation-related improvement in patients' motor function (estimated by part III of the United Parkinson's Disease Rating Score (UPDRS)). Therefore, it seems that ideally trajectories should have maximal DLOR length...

Sarcopenia is defined as low muscle function (walking speed or grip strength) in the presence of low muscle mass. A simple screening test - the SARC-F - is available to identify persons with sarcopenia. The major endocrine causes of sarcopenia are diabetes mellitus and male hypogonadism. Other causes are decreased physical activity, loss of motor neuron units, weight loss, inflammatory cytokines, reduced blood flow to muscles, very low 25(OH) vitamin D levels and decreased growth hormone and IGF-1. Treatment for sarcopenia includes resistance and aerobic exercise, leucine enriched essential amino acids, and vitamin D...

Proprioceptive sensory inputs are an integral part of the closed-loop system of locomotion. In the lamprey, a model organism for vertebrate locomotion, such sensory inputs come from intraspinal mechanosensory cells called "edge cells". These edge cells synapse directly onto interneurons in the spinal central pattern generator (CPG) circuit and allow the CPG to adjust the motor output according to how the body is bending. However, the encoding properties of the edge cells have never been fully characterized...

Recent metabolomic reports connect dysregulation of glycosphingolipids, particularly ceramide and glucosylceramide, to neurodegeneration and to motor unit dismantling in amyotrophic lateral sclerosis at late disease stage. We report here altered levels of gangliosides in the cerebrospinal fluid of amyotrophic lateral sclerosis patients in early disease stage. Conduritol B epoxide is an inhibitor of acid beta-glucosidase, and lowers glucosylceramide degradation. Glucosylceramide is the precursor for all of the more complex glycosphingolipids...

World-wide head injuries are a growing problem. In the United States alone, 1.7 million people suffer a head injury each year. While most of these injuries are mild, head injury sufferers still sustain symptoms that can have major medical and economical impacts. Moreover, repetitive mild head injuries, like those observed in active military personnel and athletes, have demonstrated a more severe and long-term set of consequences. In an effort to better understand the delayed pathological changes following multiple mild head injuries, we used a mouse model of mild closed head injury (with no motor deficits observed by rotarod testing) and measured dendritic complexity at 30 days after injury and potentially related factors up to 60 days post injury...

Objective Deep brain stimulation (DBS) for treatment of advanced Parkinson's disease (PD) has two anatomical targets: the subthalamic nucleus (STN) and the globus pallidus internus (GPI). The clinical effectiveness of these two stimulation targets was compared in the present study. Methods A systematic review and meta-analysis was performed to evaluated the postoperative changes in the United Parkinson's Disease Rating Scale (UPDRS) on- and off-phase, on-stimulation motor scores; activities of daily living score (ADLS); and levodopa equivalent dose (LED) after STN and GPI stimulation...

The control of targeted reaching is thought to be shaped by distinct subtypes of local GABAergic inhibitory neurons in primary forelimb motor cortex (M1). However, little is known about their action potential firing dynamics during reaching. To address this, we recorded the activity of parvalbumin-expressing (PV+) GABAergic neurons identified from a larger population of fast-spiking units and putative excitatory regular-spiking units in layer 5 of the mouse forelimb M1 during an M1-dependent, sensory-triggered reaching task...

BACKGROUND: Premature birth is often associated with neurodevelopmental difficulties throughout childhood. In the first three years of life, the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III) constitute one of the most used tools for assessing child development. Since Bayley-III original norms are based on United States (US) population, it remains uncertain whether their use in other countries (e.g., European) is appropriate. AIMS: This research aimed to examine neurodevelopment of preterm infants and full-term infants, using Bayley-III US norms in comparison to Italian (IT) norms...

WenYu Wu, Xiangkai Zhen, Ning Shi
The myelin sheath, which envelops axons in the vertebrate central nervous system, is crucial for the rapid conduction of action potentials. Myelin-gene regulatory factor (MRF) is a recently identified transcription factor that is required for myelin-sheath formation. Loss of MRF leads to demyelinating diseases and motor learning deficiency. MRF is a membrane-bound transcription factor that undergoes autocleavage from the endoplasmic reticulum membrane. The N-terminus of MRF contains a DNA-binding domain (DBD) that functions as a homotrimer...

BACKGROUND: Traumatic brain injury (TBI) has become the most common cause of death and disability in persons between 15 and 30 years of age, and about 10-15% of patients affected by TBI will end up in a coma. Coma caused by TBI presents a significant challenge to neuroscientists. Right median nerve electrical stimulation has been reported as a simple, inexpensive, non-invasive technique to speed recovery and improve outcomes for traumatic comatose patients. METHODS/DESIGN: This multicentre, prospective, randomised (1:1) controlled trial aims to demonstrate the efficacy and safety of electrical right median nerve stimulation (RMNS) in both accelerating emergence from coma and promoting long-term outcomes...
