In 1985 this cleft team, dissatisfied with the treatment and results from cleft lip and palate repair, began a longitudinal long-term study using dynamic maxillary orthopedics and periosteoplasty as was originally described by Drs Millard and Latham. All cases were carefully documented through adolescence, including clinical assessments, orthodontic, radiographic, and cephalometric analyses. In 1998, in this journal, we published our data on 35 complete unilateral and 10 complete bilateral cleft patients. At that time facial growth was following normal cephalometric patterns...

The study was carried out to study expression of Toll like receptors 2 (TLR2), natural/inducible Treg and Interferon-γ alongside oxidative stress and understand their significance in pediatric samples. Influence of oxidative stress on Celiac Disease was analysed by evaluating lipid peroxidation, reduced glutathione, Glutathione peroxidase, etc. A comparison was performed among CD patients, CD patients on gluten free diet (GFD), and healthy controls. Peripheral nTregs exhibited a similar pattern of reduced numbers in CD and GFD cases when compared to healthy controls...

Blocking motor cortical output with lesions or pharmacological inactivation has identified movements that require motor cortex. Yet, when and how motor cortex influences muscle activity during movement execution remains unresolved. We addressed this ambiguity using measurement and perturbation of motor cortical activity together with electromyography in mice during two forelimb movements that differ in their requirement for cortical involvement. Rapid optogenetic silencing and electrical stimulation indicated that short-latency pathways linking motor cortex with spinal motor neurons are selectively activated during one behavior...

Takahiro Mezaki
The definition of dystonia has been renewed repeatedly but always within the context of overactive muscle contractions. In dystonia the muscles unnecessary for a motion fail to be adequately suppressed because of the loss of central motor control, resulting in inappropriate movements or abnormal postures ("overflow phenomenon"). This represents, however, only one side of the disrupted motor control. Some patients complain of the inability to activate muscles necessary for the intended task despite the lack of motor paresis, as best exemplified by the apraxia of eyelid opening...

Long-term exposure to organic solvent may be related to the incidence of neuronal diseases, such as, Alzheimer's disease, depression, multiple sclerosis, dementia, Parkinson's disease. Previously, the authors reported 1,2-diacetylbenzene (DAB; a neurotoxic metabolite of 1,2-diethylbenzene) causes central and peripheral neuropathies that lead to motor neuronal deficits. Furthermore, it is known DAB increases oxidative stress and protein adduct levels and impairs hippocampal neurogenesis in mice. The authors examined the relevance of oxidative stress and tau hyperphosphorylation in the hippocampus...

The present study is an attempt to investigate the effects of long-term (75days) exposure to environmental estrogens (EE) on the swimming behaviour of zebrafish (Danio rerio). Adult zebrafish were exposed semi-statically to media containing commonly detected estrogenic water contaminants (EE2, DES and BPA) at a concentration (5ng/L) much lower than environmentally recorded levels. Time spent in swimming, surface preference, patterns and path of swimming were recorded (6mins) for each fish using two video cameras on day 15, 30 60 and 75...

BACKGROUND: Idiopathic REM sleep behavior disorder is a prodromal stage of Parkinson's disease and dementia with Lewy bodies. Hyposmia, reduced dopamine transporter binding, and expression of the brain metabolic PD-related pattern were each associated with increased risk of conversion to PD. The objective of this study was to study the relationship between the PD-related pattern, dopamine transporter binding, and olfaction in idiopathic REM sleep behavior disorder. METHODS: In this cross-sectional study, 21 idiopathic REM sleep behavior disorder subjects underwent (18) F-fluorodeoxyglucose PET, dopamine transporter imaging, and olfactory testing...

PURPOSE: A multidimensional classification approach suggests that motor control impairment subgroups exist in non-specific chronic low back pain (NSCLBP). Differences in sitting lumbar posture have been identified between two such subgroups [flexion pattern (FP) and active extension pattern (AEP)] and healthy individuals; however, functional spinal movement has not been explored. This study will evaluate whether NSCLBP subgroups exhibit regional spinal kinematic differences, compared to healthy individuals, during functional tasks...

BACKGROUND: Recent evidence suggests that impaired central sensorimotor integration may contribute to deficits in movement control experienced by people with chronic ankle instability (CAI). This study compared the effects of dual-task and walking speed on gait variability in individuals with and without CAI. METHODS: Sixteen subjects with CAI and 16 age- and gender-matched, able-bodied controls participated in this study. Stride time variability and stride length variability were measured on a treadmill under four different conditions: self-paced walking, self-paced walking with dual-task, fast walking, and fast walking with dual-task...

Gait imagery and gait observation can boost the recovery of locomotion dysfunctions; yet, a neurologically justified rationale for their clinical application is lacking as much as a direct comparison of their neural correlates. Using functional magnetic resonance imaging, we measured the neural correlates of explicit motor imagery of gait during observation of in-motion videos shot in a park with a steady cam (Virtual Walking task). In a 2 × 2 factorial design, we assessed the modulatory effect of gait observation and of foot movement execution on the neural correlates of the Virtual Walking task: in half of the trials, the participants were asked to mentally imitate a human model shown while walking along the same route (mental imitation condition); moreover, for half of all the trials, the participants also performed rhythmic ankle dorsiflexion as a proxy for stepping movements...

A variety of the available time to react (ATR) has been utilised to study knee biomechanics during reactive jump-landing tasks. The purpose was to quantify knee kinematics and kinetics during a jump-land-jump task of three possible directions as the ATR was reduced. Thirty-four recreational athletes performed 45 trials of a jump-land-jump task, during which the direction of the second jump (lateral, medial or vertical) was indicated before they initiated the first jump, the instant they initiated the first jump, 300 ms before landing, 150 ms before landing or at the instant of landing...

Non-consumptive effects (NCEs) of predators are ubiquitous in food webs with well-detailed impacts on trophic cascades over multiple levels. However, integrating NCEs with other predator-mediated interactions, like intraguild predation, as well as context-specific habitat factors that shape top-down pressure, remains a challenge. Focusing on two common seed predators, mice (Peromyscus spp.) and carabid beetles (Coleoptera: Carabidae), we quantify trophic and behavioral consequences of predation risk and availability of refuge vegetation on both intraguild predators (mice) and intraguild prey (beetles)...

Polymorphonuclear neutrophils (PMN) are the first cellular line of antibacterial host defense. They sense pathogens through recognition of pathogen-associated molecular patterns (PAMPs) by innate pattern recognition receptors, such as Toll-like receptors (TLR). The aim of this study was to investigate whether PMN sense bacterial viability and explore which viability factor could be involved in this phenomenon. For this purpose, different functions were evaluated in isolated human PMN using live Escherichia coli (Ec) and heat-killed Ec (HK-Ec)...

This case study examined how two rowers adapted their rowing patterns following crew training as a newly formed coxless pair. The two participants were expert (double-oar) single scull-boat rowers. Performing as a crew in the coxless-pair's sweep-boat, where each rower operates a single oar, on-the-water data were collected before and after a 6-week intensive team-training program. Rowing patterns were characterized by the horizontal oar angle, oar angular velocity and linear oar-water velocity profiles during the catch (minimal oar angle) to finish (maximal oar angle) half-cycles of the propulsive water phase...

The clinician-patient relationship is asymmetric in the sense that clinicians and patients have different roles in the medical consultation. Yet, there are qualities of reciprocity and mutuality in many clinician-patient encounters, and we suggest that such reciprocity may be related to the phenomenon of empathy. Empathy is often defined as the capacity to place oneself in another's position, but empathy may also be understood as a sequence of reciprocal turns-of talk, starting with the patient's expression of emotion, followed by the perception, vicarious experience, and empathic response by the clinician...

BACKGROUND: Blue sharks (Prionace glauca) are among the most abundant and widely distributed of oceanic elasmobranchs. Millions are taken annually in pelagic longline fisheries and comprise the highest component of auctioned fin weight in the international shark fin trade. Though studies of blue sharks outnumber those of other large pelagic sharks, the species' complicated and sexually segregated life history still confound current understanding of Atlantic movement patterns. Lack of detailed information regarding movement and vertical behavior continues to limit management efforts that require such data for stock assessment and sustainable catch modeling...

In order to efficiently move around, animals need to coordinate their limbs. Proper, context-dependent coupling among the neural networks underlying leg movement is necessary for generating intersegmental coordination. In the slow-walking stick insect local sensory information is very important for shaping coordination. However, central coupling mechanisms among segmental central pattern generators (CPGs) may also contribute to this. Here, we analyzed the interactions between contralateral networks that drive the depressor trochanteris muscle of the legs in both isolated and interconnected deafferented thoracic ganglia of the stick insect upon application of pilocarpine, a muscarinic acetylcholine receptor agonist...

We investigated the composition of preparatory activity of frontal eye field (FEF) neurons in monkeys performing a pursuit target selection task. In response to the orthogonal motion of a large and a small reward target, monkeys initiated pursuit biased towards the direction of large reward target motion. FEF neurons exhibited robust preparatory activity preceding movement initiation in this task. Preparatory activity consisted of two components, ramping activity that was constant across target selection conditions and a flat offset in firing rates that signaled the target selection condition...
