  1. Chin augmentation.

    2000-01-01

    The primary goal of facial aesthetic surgery is to restore, enhance, and rejuvenate the aging face to a more youthful appearance, achieving balance and harmony. The mental area must be addressed in order to have a complete synthesis of the face. The concept of augmenting the mental area with implants has evolved so significantly that it now stands by itself as an important procedure. Various autogenous implants for chin augmentation have been in use for over 100 years but have complications. The advent of synthetic materials has given rise to various types of alloplastic implants: Gore-Tex, Medpor, Supramid, Silastic, and Mersilene. No one implant is perfect for every face. This article overviews several alloplastic implants--their advantages, disadvantages, and complications, in addition to the different techniques of preparing and delivering the implants.

  2. Numb Chin Syndrome.

    Smith, Ryan M; Hassan, Anhar; Robertson, Carrie E

    2015-09-01

    "Numb chin syndrome" (NCS) refers to new-onset numbness of the lower lip and chin within the distribution of the mental or inferior alveolar nerves. While this focal numbness may be downplayed or even overlooked by patients and clinicians, in the right clinical scenario this may be the presenting symptom of an underlying malignancy. In the absence of any obvious, temporally related dental cause, there are certain conditions that clinicians should consider including orofacial and systemic malignancies as well as several inflammatory disorders. Thorough diagnostic evaluation should always be performed when no clear cause is evident. This paper will discuss the differential, recommended evaluations, and the prognosis, for a patient presenting with NCS. PMID:26210355

  3. Autosomal dominant rolandic epilepsy with speech dyspraxia.

    2000-01-01

    Autosomal Dominant Rolandic Epilepsy with Speech Dyspraxia (ADRESD) is a rare disorder which highlights the relationship between Benign Rolandic Epilepsy (BRE) and speech and language disorders. Subtle speech and language disorders have recently been well characterised in BRE. ADRESD is associated with long term, more severe speech and language difficulties. The time course of rolandic epilepsy in ADRESD is typical of that of BRE. ADRESD is inherited in an autosomal dominant manner with anticipation. It is postulated that the anticipation may be due to an, as yet unidentified, triplet repeat expansion in a gene for rolandic epilepsy. BRE follows complex inheritance but it is possible that ADRESD may hold some valuable clues to the pathogenesis of BRE. PMID:11231219

  4. Chin force in violin playing.

    PubMed

    Obata, Satoshi; Kinoshita, Hiroshi

    2012-06-01

    Force generated between the left mandible of violinists and the chinrest of the violin was examined using a force-sensing chinrest developed in this study. A strain-gauge force sensor was built, and it was fixed between the violin's top plate and a chin cup. Fifteen professional/amateur violinists held the violin statically, played musical scales with different sound properties and sounding techniques, as well as an excerpt from a Max Bruch concerto. Peak and mean forces were evaluated for each task. In a separate experiment, lateral movement of the lower teeth due to different levels of voluntary chin force exertion was measured. Static holding forces observed were 15 and 22 N with and without the help of the left hand, respectively. Peak force increased from 16 N at soft dynamics to 20 N at strong dynamics during scales. The force further increased to 29 N with the use of vibrato technique and 35 N during shifts. Tempo and hand position did not affect the force. Playing a Bruch concerto induced a mean peak force of 52 N, ranging from 31 to 82 N among the violinists. The developed force-sensing chinrest could accurately record the generated chin force. Typical chin force to stabilize the violin during ordinary musical performance was less than 30 N, but it could momentarily exceed 50 N when technically demanding musical pieces were performed. The lateral shift of the mandible was fairly small (<0.4 mm) even with high chin-force exertion, possibly due to clenching of the molars. PMID:21952980

  6. Obituary: Roland Svensson, 1950-2003

    NASA Astrophysics Data System (ADS)

    Björnsson, Claes-Ingvar

    2003-12-01

    Roland Svensson was found dead on 8 April 2003. He succumbed to the complications arising from diabetes. His contribution to the understanding of the basic properties of relativistic plasmas remains a cornerstone when studying radiation processes in many astrophysical contexts. Roland was born on 6 May 1950 in Karlshamn, Sweden. At a young age he moved with his family to Skåne, the southernmost part of Sweden. This is where he received his early education including a BS in Physics at the University of Lund in 1973. For the rest of his life, this region was home for Roland. His mother and father are Linnea Martinsson (d. 1984) and Sune Svensson. The two younger brothers are Lennart and Peter. Lennart works as a machine engineer in Sweden while Peter has settled in California as a biology professor. Roland started graduate studies in theoretical physics in Lund before receiving a Fulbright Scholarship in 1976. He then moved to the University of California in Santa Cruz and enrolled in the astronomy and astrophysics graduate program. Although his interest in astronomy had been raised during the time in Lund, it was the stimulating environment in Santa Cruz that convinced Roland to concentrate on research in astronomy. With Roland's attitude of never accepting anything unless he understood its roots, his extended background in physics served him well throughout his astronomy career; in particular, it influenced his choice of a thesis topic. At the time, the importance of relativistic temperatures attained by accreting matter in the immediate vicinity of neutron stars and black holes was becoming clear. Roland set out to make a detailed description of the physical effects electron-positron pair production and annihilation would have on such plasmas. In 1981 Roland defended his thesis titled ``Physical Properties in Relativistic Plasmas" and completed his PhD under the supervision of Bill Mathews. Roland extended the results of his thesis during two post-docs, first at

  12. Numb chin syndrome in Ewing sarcoma.

    PubMed

    Antunes, N L; Gorlick, R; Callaja, E; Lis, E

    2000-01-01

    The numb chin syndrome consists of unilateral hypesthesia of the chin and lower lip. In adults, it is often associated with metastatic disease to the mandible, base of the skull, or leptomeninges. In children, it has been associated with infiltration of the inferior alveolar nerve by leukemic cells. We describe two cases of numb chin syndrome in children with Ewing sarcoma. In a child with a solid tumor, this symptom seems to have an ominous meaning and should lead to the investigation of progressive skeletal involvement. PMID:11132220

  14. Estimating implant size in chin augmentation: A simplified approach

    PubMed Central

    Fanous, Nabil; Yoskovitch, Adi

    2003-01-01

    A receding chin, colloquially known as a weak chin, is a significant aesthetic impediment to a pleasing face. Multiple techniques exist to evaluate the poorly projecting chin, but most are imprecise when it comes to choosing the proper implant size. This choice is further complicated by the impracticality of commercially available chin implants. Most implant manufacturers offer only three to four categories of implants (small, medium, large, etc) that differ in size from one company to another, making the choice of the proper implant size a real challenge. The present paper discusses a new approach to precise sizing of the chin implant, based primarily on the degree of chin convexity (curvature of the chin pad) in the profile view. Examples of mentoplasties performed using the chin convexity principle are presented. PMID:24115862

    PubMed

    Samaitienė, Rūta; Norkūnienė, Jolita; Tumienė, Birutė; Grikinienė, Jurgita

    2013-02-01

    Although patients with benign childhood epilepsy with centrotemporal spikes exhibit a benign course of the disease, some of them display sleep and behavioral problems. Sixty-one patients with rolandic epilepsy, aged 6-11 years, were included in this study. The patients were divided into two subgroups according to the presence of seizures over the preceding 6 months. The control group comprised 25 patients without epilepsy and with similar characteristics in terms of age and sex. All patients underwent evaluation of sleep (Sleep Disturbance Scale for Children) and behavior (Lithuanian version of the Child Behaviour Checklist). Only patients who had had seizures over the preceding 6 months displayed significantly higher scores for sleep problems (disorders of excessive daytime sleepiness, disorders of sleep-wake transition, and scores for total sleep problems), worse sleep quality (longer sleep-onset latency), and behavioral problems (anxiety/depression, social problems, thought problems, attention problems, and aggressive behavior) than the patients of the control group. Our data add to evidence that active epilepsy has an impact on sleep and behavior. Clinically significant sleep problems were related to the higher risk of behavioral problems. Parents' ratings for existing sleep problems were sensitive to Sleep Disturbance Scale for Children scores above normal values. PMID:23337004

  16. Biomechanical impact response of the human chin and manubrium.

    PubMed

    Stammen, Jason A; Bolte, John H; Shaw, Joshua

    2012-03-01

    Chin-to-chest impact commonly occurs in frontal crash simulations with restrained anthropomorphic test devices (ATDs) in non-airbag situations. This study investigated the biofidelity of this contact by evaluating the impact response of both the chin and manubrium of adult post-mortem human subjects (PMHSs). The adult PMHS data were scaled to a 10-year-old (YO) human size and then compared with the Hybrid III 10YO child (HIII-10C) ATD response with the same test configurations. For both the chin and manubrium, the responses of the scaled PMHS had different characteristics than the HIII-10C ATD responses. Elevated energy impact tests to the PMHS mandible provided a mean injury tolerance value for chin impact force. Chin contact forces in the HIII-10C ATD were calculated in previously conducted HYGE sled crash simulation tests, and these contact forces were strongly correlated with the Head Injury Criterion (HIC(36 ms)). The mean injurious force from the PMHS tests corresponded to a HIC(36 ms) value that would predict an elevated injury risk if it is assumed that fractures of the chin and skull are similarly correlated with HIC(36 ms). Given the rarity of same occupant-induced chin injury in booster-seated occupants in real crash data and the disparity in chin and manubrium stiffnesses between scaled PMHS and HIII-10C ATD, the data from this study can be made use of to improve biofidelity of chin-to-manubrium contact in ATDs.

    2016-07-01

    A 51-year-old man was referred by his dentist to a maxillofacial surgeon with complaints of illness and pain in the mandible, associated with a rapidly expanding area of black gingiva and mucosa surrounding the lower front teeth. Clinically and radiographically there was evidence of an infected necrosis of the chin and floor of mouth. Following debridement at the operating room, the patient was treated at the intensive care unit for septic shock leading to prolonged hospitalisation. Investigation of the bone marrow did not provide an explanation for pancytopenia or the severity of the illness. In addition, genetic investigation of thiopurine S-methyltransferase gene showed no mutations. This gene codes for an identically named protein enzyme that contributes in the metabolising of the medicine azathioprine, used daily for an autoimmune disease. A combination of the use of azathioprine, a folic acid deficiency and sepsis led to this exceptional course of illness. Therapeutic intervention consisted of surgical debridement and treatment of the bacteraemia. Afterwards several corrective surgeries were necessary to restore oral functions. PMID:27430038

  1. Phylogeography and taxonomy of White-chinned and Spectacled Petrels.

    PubMed

    2009-07-01

    The genus Procellaria traditionally consists of four species, two restricted to New Zealand and two widespread in the Southern Ocean. All four are threatened because of incidental mortality on longlines and other fishing gear. The White-chinned Petrel P. aequinoctialis is the seabird killed in largest numbers by fisheries in the Southern Ocean. A spectacled form recently has been elevated to species status, Spectacled Petrel P. conspicillata, based on differences in morphometrics, vocalisations and breeding phenology. Cytochrome b sequences support species status for the Spectacled Petrel and show that the White-chinned Petrel has two regional populations, one around New Zealand and one throughout the South Atlantic and Indian Oceans. White-chinned and Spectacled Petrels segregated approximately 0.90 million years ago by allopatric fragmentation, and the two populations within White-chinned Petrels diverged approximately 0.35 million years ago. Climate changes and corresponding changes in ocean currents are most likely responsible for these patterns. PMID:19364537

    2008-01-01

    Pseudoxanthoma elasticum (PXE) is a rare, inherited, multisystem disorder characterized by progressive calcification and fragmentation of elastic fibers. Typically, small, yellowish papules are located on the neck and flexural areas; however, localized acquired cutaneous PXE has been proposed as a non-heritable form of the disorder. We report a patient who had normal appearing skin on the chin with an itching sensation and had PXE-like changes by skin biopsy. PMID:27303205

    2010-07-01

    Sinus tracts of odontogenic origin most commonly open into the oral cavity but occasionally may drain extraorally. The diagnosis is more difficult when necrosis of the tooth occurs in the absence of dental caries. We report a 23-year-old man with a long-standing chronic wound on the inferior aspect of the chin that was refractory to treatment. This case demonstrates the use of a simple technique to identify a necrotic mandibular incisor tooth as the source of infection. PMID:21049765

    Scheffer, I E; Jones, L; Pozzebon, M; Howell, R A; Saling, M M; Berkovic, S F

    1995-10-01

    We describe a family of 9 affected individuals in three generations with nocturnal oro-facio-brachial partial seizures, secondarily generalized partial seizures, and centro-temporal epileptiform discharges, associated with oral and speech dyspraxia and cognitive impairment. The speech disorder was prominent, but differed from that of Landau-Kleffner syndrome and of epilepsy with continuous spike and wave during slow-wave sleep. The electroclinical features of this new syndrome of autosomal dominant rolandic epilepsy resemble those of benign rolandic epilepsy, a common inherited epilepsy of childhood. This family shows clinical anticipation of the seizure disorder, the oral and speech dyspraxia, and cognitive dysfunction, suggesting that the genetic mechanism could be expansion of an unstable triplet repeat. Molecular studies on this syndrome, where the inheritance pattern is clear, could also be relevant to identifying a gene for benign rolandic epilepsy where anticipation does not occur and the mode of inheritance is uncertain.

    2015-02-01

    We describe a group of 26 children with no prior history of seizures consistent with benign rolandic epilepsy who had rolandic spikes found coincidentally on EEG. A retrospective chart review as well as phone and email follow-ups with families were completed to assess long-term outcomes. A subset of this group (n=7) with reported comorbid language or learning difficulties was then given an empiric trial of levetiracetam. Seven (27%) children eventually developed seizures, with a median of 14months after the abnormal EEG. Of the 7 children ever treated with levetiracetam, 5 exhibited beneficial effects on learning, speech, or behavior. Side effects reported were mild and included irritability and headache. Incidental rolandic spikes may represent a discrete neurologic condition, with approximately one-quarter of the patients later developing epilepsy. Some of these children may experience improved intellectual functioning with levetiracetam. PMID:25623811

    1995-05-01

    The plethora of problematic techniques for improving minor chin recessions has left the plastic surgeon inevitably uncertain of the most effective remedy. Research we began in 1968 has led us to the development of a new biphasic polymer and minimally invasive implantation techniques aimed at solving the soft-tissue deficiency dilemma. Bioplastique consists of inert, textured particles of critical dimension dispersed within a bioexcretable gel vehicle. Previous experimentation in rabbit ears has shown that the gel component is rapidly phagocytosed, excreted, and replaced by a fibrin matrix within 3 days. The matrix is then replaced by host collagen, gradually forming a stable encasement around each microparticle. Further evaluation has revealed that the implant resists migration and absorption. Based on these encouraging results, a clinical phase was initiated. Thirteen patients lacking chin prominence have subsequently been improved with Bioplastique implants. The infection rate was 0 percent, and other complications were minor. At 26 months, no evidence of migration or absorption has been observed, and the aesthetic results remain. PMID:7732146

    1981-01-01

    The performance of a "chin" nozzle which diverts flow in a downward direction immediately downstream of a fan typical of designs suitable for V/STOL A applications was evaluated. Back pressure distortion to the fan and fan discharge pressure distortion were also measured. Results show that the distortion is significant at the closest spacing between the fan exit and cascade entrance tested, and that the chin nozzle performance deteriorates with increased flow diversion to the chin nozzle. Color oil flow visualization on video tape and still photos were also obtained. Tests were conducted behind a 12" model fan in the NASA-Lewis fan calibration facility.

    Introduction Rolandic epilepsy (RE) is a childhood epilepsy with centrotemporal (rolandic) spikes, that is increasingly associated with language impairment. In this study, we tested for a white matter (connectivity) correlate, employing diffusion weighted MRI and language testing. Methods Twenty-three children with RE and 23 matched controls (age: 8–14 years) underwent structural (T1-weighted) and diffusion-weighted MRI (b = 1200 s/mm2, 66 gradient directions) at 3T, as well as neuropsychological language testing. Combining tractography and a cortical segmentation derived from the T1-scan, the rolandic tract were reconstructed (pre- and postcentral gyri), and tract fractional anisotropy (FA) values were compared between patients and controls. Aberrant tracts were tested for correlations with language performance. Results Several reductions of tract FA were found in patients compared to controls, mostly in the left hemisphere; the most significant effects involved the left inferior frontal (p = 0.005) and supramarginal (p = 0.004) gyrus. In the patient group, lower tract FA values were correlated with lower language performance, among others for the connection between the left postcentral and inferior frontal gyrus (p = 0.043, R = 0.43). Conclusion In RE, structural connectivity is reduced for several connections involving the rolandic regions, from which the epileptiform activity originates. Most of these aberrant tracts involve the left (typically language mediating) hemisphere, notably the pars opercularis of the inferior frontal gyrus (Broca’s area) and the supramarginal gyrus (Wernicke’s area). For the former, reduced language performance for lower tract FA was found in the patients. These findings provide a first microstructural white matter correlate for language impairment in RE.

    In follicular keratosis of the chin, keratotic follicular papules occur on the chin and jaw due to localized prolonged pressure and friction on the naked skin. We present one patient with this disorder. The dermatoscopic examination revealed many well-demarcated yellow spindle bodies in the patchy lesion. Therapy with 1.24R-dihydroxyvitamin D3 ointment was effective during the treatment but had no residual positive effect. PMID:17845168

    2015-06-01

    The presence of a prominent chin in modern humans has been viewed by some researchers as an architectural adaptation to buttress the anterior corpus from bending stresses during mastication. In contrast, ontogenetic studies of mandibular symphyseal form suggest that a prominent chin results from the complex spatial interaction between the symphysis and surrounding soft tissue and skeletal anatomy during development. While variation in chin prominence is clearly influenced by differential growth and spatial constraints, it is unclear to what degree these developmental dynamics influence the mechanical properties of the symphysis. That is, do ontogenetic changes in symphyseal shape result in increased symphyseal bending resistance? We examined ontogenetic changes in the mechanical properties and shape of the symphysis using subjects from a longitudinal cephalometric growth study with ages ranging from 3 to 20+ years. We first examined whether ontogenetic changes in symphyseal shape were correlated with symphyseal vertical bending and wishboning resistance using multivariate regression. Secondly, we examined ontogenetic scaling of bending resistance relative to bending moment arm lengths. An ontogenetic increase in chin prominence was associated with decreased vertical bending resistance, while wishboning resistance was uncorrelated with ontogenetic development of the chin. Relative to bending moment arm lengths, vertical bending resistance scaled with significant negative allometry whereas wishboning resistance scaled isometrically. These results suggest a complex interaction between symphyseal ontogeny and bending resistance, and indicate that ontogenetic increases in chin projection do not provide greater bending resistance to the mandibular symphysis.

    During the course of human evolution, the retraction of the face underneath the braincase, and closer to the cervical column, has reduced the horizontal dimension of the vocal tract. By contrast, the relative size of the tongue has not been reduced, implying a rearrangement of the space at the back of the vocal tract to allow breathing and swallowing. This may have left a morphological signature such as a chin (mental prominence) that can potentially be interpreted in Homo. Long considered an autopomorphic trait of Homo sapiens, various extinct hominins show different forms of mental prominence. These features may be the evolutionary by-product of equivalent developmental constraints correlated with an enlarged tongue. In order to investigate developmental mechanisms related to this hypothesis, we compare modern 34 human infants against 8 chimpanzee fetuses, whom development of the mandibular symphysis passes through similar stages. The study sets out to test that the shared ontogenetic shape changes of the symphysis observed in both species are driven by the same factor--space restriction at the back of the vocal tract and the associated arrangement of the tongue and hyoid bone. We apply geometric morphometric methods to extensive three-dimensional anatomical landmarks and semilandmarks configuration, capturing the geometry of the cervico-craniofacial complex including the hyoid bone, tongue muscle and the mandible. We demonstrate that in both species, the forward displacement of the mental region derives from the arrangement of the tongue and hyoid bone, in order to cope with the relative horizontal narrowing of the oral cavity. Because humans and chimpanzees share this pattern of developmental integration, the different forms of mental prominence seen in some extinct hominids likely originate from equivalent ontogenetic constraints. Variations in this process could account for similar morphologies. PMID:24260566

    Since the first descriptions of Rolandic Epilepsy or benign epilepsy with centrotemporal spikes (BECTS), typical and atypical forms have been reported. Indeed, classical focal seizures are sometimes associated with various atypical ictal symptoms and cognitive or behavioural disorders. In an effort to define early clinical and EEG criteria allowing early distinction between typical and atypical forms, we recently conducted a prospective study in a cohort of children with Rolandic Epilepsy. The results of this study have been reported elsewhere. We now discuss the semiological characteristics, and comment on the video-EEG data collected during this study. Symptoms were classified into three major categories: "classical focal seizures"; "spike and wave related symptoms"; and "paraictal symptoms". Classical focal seizures constitute the electroclinical expression of the development and the propagation of a focal cortical neuronal discharge. "Spike and wave related symptoms" are brief neurological or neuropsychological phenomena having a relatively strict temporal relation with individual components of isolated focal or generalized spikes and waves. "Paraictal symptoms" consist of acquired progressive and fluctuating motor or cognitive deficits and are not directly correlated with Todd paralysis. We present detailed video-EEG material of selected cases and discuss the usefulness of such distinctions in terminology. We suggest that variability in clinical expression probably reflects the implication of different pathophysiological mechanisms, which in turn could explain differences in sensitivity to treatment.

    We tested the hypothesis of a relationship between heart rate variability (HRV) and Rolandic mu rhythms in relaxed condition of resting state. Resting state eyes-closed electroencephalographic (EEG) and electrocardiographic (ECG) data were recorded (10-20 System) in 42 healthy adults. EEG rhythms of interest were high-frequency alpha (10.5-13Hz) and low-frequency beta (13-20Hz), which are supposed to form Rolandic mu rhythms. Rolandic and occipital (control) EEG sources were estimated by LORETA software. Results showed a statistically significant (p<0.05, corrected) negative correlation across all subjects between Rolandic cortical sources of low-frequency beta rhythms and the low-frequency band power (LF, 0.04-0.15Hz) of tachogram spectrum as an index of HRV. The lower the amplitude of Rolandic sources of low-frequency beta rhythms (as a putative sign of activity of somatomotor cortex), the higher the LF band power of tachogram spectrum (as a putative sign of sympathetic activity). This effect was specific as there was neither a similar correlation between these EEG rhythms and high-frequency band power of tachogram spectrum (as a putative sign of parasympathetic vagal activity) neither between occipital sources of low-frequency beta rhythms (as a putative sign of activity of visual cortex) and LF band power of tachogram spectrum. These results suggest that Rolandic low-frequency beta rhythms are related to sympathetic activity regulating heart rate, as a dynamic neurophysiologic oscillatory mechanism sub-serving the interaction between brain neural populations involved in somatomotor control and brain neural populations regulating ANS signals to heart for on-going homeostatic adaptations.

    ChinArray is a dense portable broadband seismic network to cover the entire continental China, and the Phase I is deployed along the north-south seismic belt in southwest China. In this study, we analyze seismic data recorded on the ChinArray following the February 15, 2013 Chelyabinsk (Russia) meteor. This was the largest known object entering the Earth's atmosphere since the 1908 Tunguska meteor. The seismic energy radiated from this event was recorded by seismic stations worldwide including the dense ChinArray that are more than 4000 km away. The weak signal from the meteor event was contaminated by a magnitude 5.8 Tonga earthquake occurred ~20 min earlier. To test the feasibility of detecting the weak seismic signals from the meteor event, we compute vespagram and perform F-K analysis to the surface-wave data. We identify a seismic phase with back azimuth (BAZ) of 329.7° and slowness of 34.73 s/deg, corresponding to the surface wave from the Russian meteor event (BAZ ~325.97°). The surface magnitude (M S) of the meteor event is 3.94 ± 0.18. We also perform similar analysis on the data from the broadband array F-net in Japan, and find the BAZ of the surface waves to be 316.61°. With the different BAZs of ChinArray and F-net, we locate the Russian meteor event at 58.80°N, 58.72°E. The relatively large mislocation (~438 km as compared with 55.15°N, 61.41°E by others) may be a result of the bending propagation path of surface waves, which deviates from the great circle path. Our results suggest that the dense ChinArray and its subarrays could be used to detect weak signals at teleseismic distances.

  3. Fiddler's neck: Chin rest-associated irritant contact dermatitis and allergic contact dermatitis in a violin player.

    Fiddler's neck refers to an irritant contact dermatitis on the submandibular neck of violin and viola players and an allergic contact dermatitis to nickel from the bracket attaching the violin to the chin rest on the violinist's supraclavicular neck. A 26-year-old woman developed submandibular and supraclavicular left neck lesions corresponding to the locations of the chin rest and bracket that was attached to her violin that held it against her neck when she played. Substitution of a composite chin rest, which did not contain nickel, and the short-term application of a low potency topical corticosteroid cream, resulted in complete resolution of the allergic contact dermatitis supraclavicular neck lesion. The irritant contact dermatitis submandibular neck lesion persisted. In conclusion, violin players are predisposed to developing irritant contact dermatitis or allergic contact dermatitis from the chin rest. We respectfully suggest that the submandibular neck lesions from contact with the chin rest be referred to as 'fiddler's neck - type 1,' whereas the supraclavicular neck lesions resulting from contact of the bracket holding the chin rest in place be called 'fiddler's neck - type 2.' A composite chin rest should be considered in patients with a preceding history of allergic contact dermatitis to nickel. PMID:23031377

    INTRODUCTION:: This study was conducted to determine if there are differences in pressure on a violin chin rest during performance due to changes in shoulder pads, chin rests, or pieces of music performed. It was also hypothesized that these differences would correlate with anthropometric measurements made of the subjects' necks and shoulders. METHODS::: A Novel EMED pad was used over the chin rest, containing 120 sensors, each one centimetre squared. The sampling rate was 50 Hz. A total of ten subjects, all professional violinists, performed excerpts from a Bruch violin concerto and a Handel sonata. Anthropometric measurements were made of the subjects' necks and shoulders. Each subject began by using his own violin with his usual shoulder pad and chin rest set-up, and then with the author's violin. Two different shoulder pads and three different chin rests were placed on the violin, in all possible combinations, for both pieces of music. This resulted in a total of fourteen conditions given in randomized order for each subject. Subjects were asked to give verbal feedback regarding the comfort and ease of playing of each shoulder pad and chin rest. Data was collected for three trials of each condition, and a mean for the three trials was obtained for each dependent variable. The five dependent variables were: peak pressure, maximum force, pressure/time integral and force/time integral, and total contact area. Intraclass coefficients of reliability were calculated for the dependent variables. Pearson's correlation coefficients were computed to determine if there were significant relationships between the five dependent variables and violin height, shoulder width, and neck length. RESULTS:: Pressure/time integral achieved the highest reliability with a coefficient of 0.9310, followed by peak pressure at 0.9152, force/time integral at 0.8817, maximum force at 0.8685, and total area at 0.8571.

    Numb chin syndrome is a rare sensory neuropathy of the mental nerve characterized by numbness, hypoesthesia, paraesthesia, and very rarely pain. Dental causes, especially iatrogenic ones, maxillofacial trauma, or malignant neoplasm are etiologic factors for this rare syndrome. Many malignant and metastatic neoplasms are causing this syndrome, like primary osteosarcoma, squamous cell carcinoma, and mandibular metastasis of primary carcinoma of breast, lung, thyroid, kidney, prostate, and nasopharynx. Haematological malignancies like acute lymphocytic leukaemia, Hodgkin and non-Hodgkin lymphoma, and myeloma can cause this neuropathy. The authors report a case of a 71-year-old woman in which the numb chin syndrome was the first symptom of the diffuse large B-cell lymphoma, which caused infiltration and reabsorption of the alveolar ridge and lower mandibular cortex. A biopsy of the mass was performed on fragments of tissue collected from the mandibular periosteum, medullary and cortical mandibular bone, and inferior alveolar nerve. PMID:25580308

However, a clear and testable definition of boredom should be established prior to experimental manipulation of the construct.

    Purpose When swallowing efficiency is impaired, residue accumulates in the pharynx. Cued or spontaneous swallows in the head neutral position do not always successfully clear residue. We investigated the impact of a novel maneuver on residue clearance by combining a head turn with the chin down posture. Methods Data were collected from 26 participants who demonstrated persistent vallecular residue after an initial head neutral clearance swallow in videofluoroscopy. Participants were cued to perform a head-turn-plus-chin-down swallow, with the direction of head turn randomized. Pixel-based measures of residue in the vallecular space before and after the maneuver were made on still frame lateral images using ImageJ software. Measures of % full and the Normalized Residue Ratio Scale (NRRS) were extracted. Univariate analyses of variance were used to detect significant reductions in residue. Results On average, pre-maneuver measures showed residue filling 56-73% of the valleculae, depending on stimulus consistency (NRRS scores: 0.2-0.4). More than 80% of pre-swallow measures displayed NRRS ratios > 0.06, a threshold previously linked to increased risk of post-swallow aspiration. Conclusion The head-turn-plus-chin-down maneuver achieved significant reductions in residue for thin and nectar-thick fluids, suggesting that this maneuver can be effective in reducing persistent vallecular residue with these consistencies.

    Successful joint actions require precise temporal and spatial coordination between individuals who aim to achieve a common goal. A growing number of behavioral data suggest that to efficiently couple and coordinate a joint task, the actors have to represent both own and the partner’s actions. However it is unclear how the motor system is specifically recruited for joint actions. To find out how the goal and the presence of the partner’s hand can impact the motor activity during joint action, we assessed the functional state of 16 participants’ motor cortex during observation and associated motor imagery of joint actions, individual actions, and non-goal-directed actions performed with either 1 or 2 hands. As an indicator of the functional state of the motor cortex, we used the reactivity of the rolandic magnetoencephalographic (MEG) beta rhythm following median-nerve stimulation. Motor imagery combined with action observation was associated with activation of the observer’s motor cortex, mainly in the hemisphere contralateral to the viewed (and at the same time imagined) hand actions. The motor-cortex involvement was enhanced when the goal of the actions was visible but also, in the ipsilateral hemisphere, when the partner’s hand was visible in the display. During joint action, the partner’s action, in addition to the participant’s own action, thus seems to be represented in the motor cortex so that it can be triggered by the mere presence of an acting hand in the peripersonal space.

    Introduction Alveolar and skeletal chin dimensions with facial height have an impact on diagnosis and treatment planning in orthodontic patients and serves as a reference landmark for facial aesthetics. Aim To evaluate the alveolar and skeleton chin dimensions among different divergent patterns, to evaluate the lower face height in different divergent growth patterns, to give an estimate to the oral surgeon for any adjunctive procedure. Materials and Methods The study includes a total sample of 45 non-growing individuals (26 males and 19 females) from the archival records of the Orthodontic Department with age ranging between 18-25 years, classified into different divergent patterns based on the mandibular plane angle. The sample was divided into three groups, of which 15 patients in each group were evaluated: Group-1: Normodivergent, Group-2: Hypodivergent and Group-3: Hyperdivergent patterns respectively. Standardized digital lateral cephalograms and antero-posterior cephalograms of these patients were obtained in Natural Head Position (NHP). Results The results of the retrospective cephalometeric study were statistically analyzed by using ANOVA and Tukey’s multiple post hoc test which showed that hard tissue chin measurement were greater in hypodivergent group (13.7mm) and the increased lower facial height showed statistically significant difference in high mandibular plane angle group (59.6mm). In antero-posterior cephalograms the transverse width showed statistically significant difference in normodivergent group (32.60mm). Conclusion The anterio-posterior width of the symphysis was higher in hypodivergent growth pattern, whereas vertical height of the symphysis was greater in hyperdivergent group. The lower facial height among three groups showed statistically significant difference among hyperdivergent group. In comparison of all the three groups in Anterio-Posterior (AP) cephalograms, statistically significant difference was noted in normodivergent group

    Rolandic epilepsy (RE) is the most common idiopathic focal childhood epilepsy. Its molecular basis is largely unknown and a complex genetic etiology is assumed in the majority of affected individuals. The present study tested whether six large recurrent copy number variants at 1q21, 15q11.2, 15q13.3, 16p11.2, 16p13.11 and 22q11.2 previously associated with neurodevelopmental disorders also increase risk of RE. Our association analyses revealed a significant excess of the 600 kb genomic duplication at the 16p11.2 locus (chr16: 29.5-30.1 Mb) in 393 unrelated patients with typical (n = 339) and atypical (ARE; n = 54) RE compared with the prevalence in 65,046 European population controls (5/393 cases versus 32/65,046 controls; Fisher's exact test P = 2.83 × 10(-6), odds ratio = 26.2, 95% confidence interval: 7.9-68.2). In contrast, the 16p11.2 duplication was not detected in 1738 European epilepsy patients with either temporal lobe epilepsy (n = 330) and genetic generalized epilepsies (n = 1408), suggesting a selective enrichment of the 16p11.2 duplication in idiopathic focal childhood epilepsies (Fisher's exact test P = 2.1 × 10(-4)). In a subsequent screen among children carrying the 16p11.2 600 kb rearrangement we identified three patients with RE-spectrum epilepsies in 117 duplication carriers (2.6%) but none in 202 carriers of the reciprocal deletion. Our results suggest that the 16p11.2 duplication represents a significant genetic risk factor for typical and atypical RE. PMID:24939913

    Introduction: Rolandic epilepsy (RE) manifests during a critical phase of brain development, and has been associated with language impairments. Concordant abnormalities in structural and functional connectivity (SC and FC) have been described before. As SC and FC are under mutual influence, the current study investigates abnormalities in the SC-FC synergy in RE. Methods: Twenty-two children with RE (age, mean ± SD: 11.3 ± 2.0 y) and 22 healthy controls (age 10.5 ± 1.6 y) underwent structural, diffusion weighted, and resting-state functional magnetic resonance imaging (MRI) at 3T. The probabilistic anatomical landmarks atlas was used to parcellate the (sub)cortical gray matter. Constrained spherical deconvolution tractography and correlation of time series were used to assess SC and FC, respectively. The SC-FC correlation was assessed as a function of age for the non-zero structural connections over a range of sparsity values (0.01–0.75). A modularity analysis was performed on the mean SC network of the controls to localize potential global effects to subnetworks. SC and FC were also assessed separately using graph analysis. Results: The SC-FC correlation was significantly reduced in children with RE compared to healthy controls, especially for the youngest participants. This effect was most pronounced in a left and a right centro-temporal network, as well as in a medial parietal network. Graph analysis revealed no prominent abnormalities in SC or FC network organization. Conclusion: Since SC and FC converge during normal maturation, our finding of reduced SC-FC correlation illustrates impaired synergy between brain structure and function. More specifically, since this effect was most pronounced in the youngest participants, RE may represent a developmental disorder of delayed brain network maturation. The observed effects seem especially attributable to medial parietal connections, which forms an intermediate between bilateral centro-temporal modules of

    The demand for augmentation of central and lower facial features continues to increase. There are several safe and effective materials available for this purpose, and techniques have become highly refined. The relative strengths and weaknesses of silicone, expanded polytetrafluoroethylene (ePTFE), high-density polyethylene (HDPE), and merseline mesh are discussed for augmentation of the chin/pre-jowl sulcus and cheek. Materials for augmentation of the nasolabial folds (NLF) are also discussed. There are various forms of solid ePTFE that have been developed for soft tissue augmentation. These are particularly well suited for the NLF. Techniques for facial skeletal and soft tissue augmentation are presented. PMID:11518979

    Study Objectives: A chinstrap is potentially useful to reduce unintentional air leak by preventing mouth opening during PAP treatment. This study examines whether the addition of a chinstrap to PAP therapy has any effect on adherence, nightly duration of use, air leak, and residual AHI. Methods: This was a retrospective study performed at an AASM-accredited VAMC sleep center. Clinical sleep data of veterans (n = 124) prescribed PAP therapy for sleep apnea was evaluated, and the effect of chinstrap use vs non-use on the above parameters was assessed. Results: Chinstrap users had significantly greater PAP adherence, longer nightly duration of PAP use, lower residual AHI and lower leak compared to chinstrap non-users at first follow up visit. Conclusions: The addition of a chin strap to PAP therapy is a simple and inexpensive method of increasing PAP adherence. Citation: Knowles SR; O'Brien DT; Zhang S; Devara A; Rowley JA.

    Mandibular torus fracture as a result of accidental trauma has not been reported to date in the dental literature. This study describes the case of a young adult male who suffered multiple fractures affecting the teeth and mandibular torus secondary to chin area trauma due to a bicycle accident; the first manifestation of bone damage being left unilateral paraesthesia of the lip. An occlusal x-ray study of the affected area was made to evaluate possible fracture, as unlike centred periapical x-rays and orthopantomography, it is able to reveal the existence of a fracture line of the alveolar wall. In the associated presence of paraesthesia, a computed tomographic study is advisable. PMID:16003417

    GM2 gangliosidosis is a fatal lysosomal storage disease caused by a deficiency of β-hexosaminidase (EC 3.2.1.52). There are two major isoforms of the enzyme: hexosaminidase A composed of an α and a β subunit (encoded by HEXA and HEXB genes, respectively); and, hexosaminidase B composed of two β subunits. Hexosaminidase A requires an activator protein encoded by GM2A to catabolize GM2 ganglioside, but even in the absence of the activator protein, it can hydrolyze the synthetic substrates commonly used to assess enzyme activity. GM2 gangliosidosis has been reported in Japanese Chin dogs, and we identified the disease in two related Japanese Chin dogs based on clinical signs, histopathology and elevated brain GM2 gangliosides. As in previous reports, we found normal or elevated hexosaminidase activity when measured with the synthetic substrates. This suggested that the canine disease is analogous to human AB variant of G(M2) gangliosidosis, which results from mutations in GM2A. However, only common neutral single nucleotide polymorphisms were found upon sequence analysis of the canine ortholog of GM2A from the affected Japanese Chins. When the same DNA samples were used to sequence HEXA, we identified a homozygous HEXA:c967G>A transition which predicts a p.E323K substitution. The glutamyl moiety at 323 is known to make an essential contribution to the active site of hexosaminidase A, and none of the 128 normal Japanese Chins and 92 normal dogs of other breeds that we tested was homozygous for HEXA:c967A. Thus it appears that the HEXA:c967G>A transition is responsible for the GM2 gangliosidosis in Japanese Chins. PMID:23266199

Persson's (2012a) additional emphases on ethnocentricity, cultural bias and strong threads of influence from the global economy also are helpful. They shed light on some strong contextual influences that shape the…

    Jane Roland Martin's later work, especially as represented in "The Schoolhome: Rethinking Schools for Changing Families," has been attacked as vague, essentialistic, and a formula for the (re)feminization of education. This paper does not attempt to defend Martin against these criticisms because such a defense seems impossible for…

    Eleven infant boys presented with chin-up head posture, tonic downgaze and, on attempted upgaze, large-amplitude upward saccades with deceleration during the slow phase downward. The gaze-evoked upward saccades disappeared at the age of 2 or 3 years. In addition, they had high-frequency, small-amplitude horizontal pendular nystagmus that remained. Among these infant boys were 2 pairs of maternally related half-brothers, 2 cousins, and 2 siblings. Visual acuity ranged from 0.1 to 0.6, ERG-amplitudes (both A- and B-wave) were reduced, and severe myopia was found in 5 cases. Eight boys had CACNA1F mutations, and 1 boy had a NYX mutation, compatible with incomplete or complete congenital stationary nightblindness (iCSNB or cCSNB), respectively. This points to a defective synapse between the rod and the ON-bipolar cell causing the motility disorder: CACNA1F is located on the rod side of this synapse, whereas NYX is located on the side of the ON-bipolar cell. The coexistence of horizontal and vertical nystagmus has been previously described in dark-reared cats. PMID:20001510

    The objective of this paper was to evaluate histologically the tissue reaction in the chin after a vertical augmentation using interpositional porous polyethylene (PPE) implants in monkeys. Six monkeys (Cebus apella) underwent an anterior horizontal mandibular osteotomy with implantation of an interpositional PPE implant to increase the vertical height. The animals were sacrificed 5 months postoperatively. Histologic preparations were stained with hematoxylin and eosin. The perimeter of the interface between the implant and the bone, the implant and the trabecular space, and the implant and the fibrous capsule were quantified using the NIH Image Analysis System (Image 1.60/PPC). In addition, the Tukey test was done. The study demonstrated that bone growth takes place within the pores of the implant; a fibrous capsule exists in some animals, where the implant has contact with the periosteum and mentalis muscle with few chronic inflammatory cells; and the 3 different tissues responded in statistically different manners. Perimeter analysis revealed 68.9% implant-bone contact, 22.9% implant-fibrous tissue contact, and 8.2% implant-trabecular space contact. PMID:10686842

    The etiologies of facial pain are innumerable, thus facial pain misdiagnosis and resultant mismanagement is common. Numb chin syndrome presents with hypoesthesia and/or anesthesia in the dermatomal distribution of the inferior alveolar or the mental nerve. In this case report, we will discuss a case of intractable facial pain in a 57-year-old male with a history of esophageal adenocarcinoma who was initially misdiagnosed and treated as trigeminal neuralgia. During clinical examination, the loss of sensation in the inferior alveolar nerve distribution was identified and led to the diagnosis of mandibular metastasis. The details of the clinical presentation will be discussed in the context of accurate identification and diagnosis. Focal radiation to the metastatic location along with sphenopalatine ganglion radiofrequency ablation and medication management provided significant pain relief. This case report provides additional information to the current medical knowledge and it enhances the clinical vigilance of the clinicians when they encounter similar cases. We concluded that patients with a history of neoplasms who present with atypical symptoms of facial pain should undergo further investigation with advanced imaging. Targeted treatment based on an accurate diagnosis is the foundation of pain management. PMID:25606033

    A 7 yr old, neutered male Japanese chin presented to the Cummings School of Veterinary Medicine at Tufts University (CSVMTU) for evaluation of chronic unilateral orbital swelling that worsened following an episode of respiratory distress. The left eye had been enucleated 5 yr previously. Intermittent mild-to-moderate left orbital swelling had been noted by the owner since the initial surgery. Examination demonstrated a moderate-to-severe, soft, fluctuant swelling involving the left orbit with erythema of the overlying skin. Crepitus was noted over the occipital tuberosity. Computed tomography revealed a large volume of gas involving the left orbit. The gas extended caudally within the subcutaneous tissues to both hemimandibles, dorsal to the cranium, and partially surrounded the cranial neck. The presence of a mucosa-lined, air-filled space with a patent nasolacrimal duct was noted on orbital exploration. The lining was removed and the duct closed. Histopathology confirmed the presence of an epithelial lining. No recurrence of the swelling was observed on examination 8 wk after surgery. This is the first report documenting acute worsening of orbital swelling following an episode of respiratory distress. This case highlights the importance of addressing the nasolacrimal duct while performing an enculeation in a brachycephalic dog. PMID:26535462

    Clear cell type of renal cell carcinoma (RCC) is most common urological malignancy. Several diagnostic challenges arise when it presents as a cutaneous nodule, being an uncommon presentation. Fine needle aspiration cytology (FNAC) of a cutaneous nodule is crucial for distinguishing primary tumours from metastatic tumours because cutaneous metastases represent a terminal stage of illness. Due to considerable overlap of cytomorphological features determination of primary warrants need of detailed clinical history and close inspection of every cytological detail. We report here a case of cutaneous metastasis of RCC on chin in a patient 11 years after nephrectomy. Though there are reports of RCC metastases diagnosed on histology, there are fewer cytology case reports. Cytological differential diagnosis has been discussed for arriving at the final diagnosis in case of clear cell tumours. Early and accurate diagnosis is mandatory for optimal treatment. Cytodiagnosis of cutaneous metastasis of RCC is uncommon due to its low suspicion index in cutaneous nodules. More so, it presents late and an unusual sites due to its resemblance to common dermatological diseases. PMID:26894079

    The China Seismic Array Program (ChinArray) is to understand the deep structures and their relationship to seismic activity in the continent of China. The first phase of the program was carried out in the region of Yunnan, in the southeastern margin of the Tibetan Plateau. How is the relationship between the Plateau and surroundings blocks? How is the characteristics of the deep structures, especially along the faults we observed on the surface? We also want to know more about deep background structures where the strong earthquake occurred. The seismic array includes 350 broadband portable seismic stations, with the average interval of 35km. By using the seismic inversion methods, we obtained the 3-D seismic velocity structure, the shape of the Moho discontinuities, the seismic anisotropy of the lithospheric medium. These results could be used to build the 3-D model of the lithospheric structures. The low velocity zone in low crust was founded inside the Plateau area. Moho depth distribution was obtained from the seismic receiver function. They showed the different margins of the extension materials of Tibetan Plateau in deep from that on the surface. The Red River fault is the border of the blocks in crust. While it has no remarkable variation in mantle beneath the Red River fault. The seismic anisotropy figure showed that the directions of the splitted fast S waves are different in northern and southern part of the Yunnan area. We deduced that the extrusion of Tibetan Plateau was obstructed below the crust around the latitude of 26°N.

    Since the 1908 Tunguska event, the largest meteor was reported on 15 February 2013 around 03:20:00 UTC. The fireball exploded and dropped near Chelyabinsk, Russia. Massive energy released by meteor crash was recorded by the 500-station ChinArray deployed in southwest China at distances more than 4000 kilometers from the meteor event. About 20 minutes before the meteor event, an M5.8 event occurred in Tonga, and produced seismic waves that overlapped with the seismic signals from the meteor event. Here we separate the seismic phases from the two events using standard array processing techniques such as F-K analysis, beam-forming, and vespagram in the Generic Array Processing (GAP) code (Koper, 2005). F-K analysis provides an effective way to calculate the back azimuth and slowness of a seismic phase. With this method, we identify a phase with back azimuth of 339.1°and slowness of 37.46sec/deg as surface wave from meteor. Beam-forming technique can be used to amplify the signal of meteor generated surface wave and suppress incoherent noise and phases with different slowness from the Tonga event. Vespagram shows the appropriate slowness of ~35sec/deg at arrival of meteor's phase, confirming the F-K detection of surface wave. From the surface wave observation, we conclude that the seismic source of meteor is located on 61.39N 58.70E, which is ~700km away from the USGS location (55.15N 61.41E). Using the Praha relation [Karnik et al., 1962], we estimate a magnitude of Ms=3.94±0.18 in accordance with that of Ms~3.7 [Benoit Tauzin et al., 2013]. Our result is comparable to other observations with shorter epicentral distances, suggesting that dense seismic arrays can be used to detect weak seismic signals at long-range distances.

    Nine children (five males, four females; age range 6 years 1 month to 11 years 1 month) affected by benign epilepsy of childhood with centrotemporal or Rolandic spikes (BECRS) with EEG evidence of marked activation of interictal epileptic discharges (IEDs) during sleep, and nine unaffected control children matched for age, sex, and socioeconomic status, were enrolled in a prospective study. At the time of detection of IED activation during sleep, patients showed a mean Full-Scale IQ score within the normal range, but significantly below that of control participants; neuropsychological assessment revealed disorders in visuospatial short-term memory (Corsi's Block Tapping Test), attention, and cognitive flexibility (Trail Making Test and Stroop Color-Word Test), picture naming, and fluency (Benton's Naming Test and Word Fluency), visuoperceptual skill (Ghent-Poppelreuter and Street Gestalt Completion Tests) and visuomotor coordination (Bender Test). After detection of IED activation during sleep, children were followed up for 2 years. At the time of IED remission (T1), neuropsychological re-evaluation showed a notable increase in IQ score and a significant improvement (t-test: p<0.007) in visuomotor coordination, non-verbal short-term memory, sustained attention and mental flexibility, picture naming, and visual-perceptual performance. At T1, patients' performance did not differ from the controls (Mann-Whitney U test). PMID:11409830

    Background The Chin State of Burma (also known as Myanmar) is an isolated ethnic minority area with poor health outcomes and reports of food insecurity and human rights violations. We report on a population-based assessment of health and human rights in Chin State. We sought to quantify reported human rights violations in Chin State and associations between these reported violations and health status at the household level. Methods and Findings Multistaged household cluster sampling was done. Heads of household were interviewed on demographics, access to health care, health status, food insecurity, forced displacement, forced labor, and other human rights violations during the preceding 12 months. Ratios of the prevalence of household hunger comparing exposed and unexposed to each reported violation were estimated using binomial regression, and 95% confidence intervals (CIs) were constructed. Multivariate models were done to adjust for possible confounders. Overall, 91.9% of households (95% CI 89.7%–94.1%) reported forced labor in the past 12 months. Forty-three percent of households met FANTA-2 (Food and Nutrition Technical Assistance II project) definitions for moderate to severe household hunger. Common violations reported were food theft, livestock theft or killing, forced displacement, beatings and torture, detentions, disappearances, and religious and ethnic persecution. Self reporting of multiple rights abuses was independently associated with household hunger. Conclusions Our findings indicate widespread self-reports of human rights violations. The nature and extent of these violations may warrant investigation by the United Nations or International Criminal Court. Please see later in the article for the Editors' Summary PMID:21346799

    Sufficient ground water to provide about 2.1 million acre-feet in a 25-year period is available for delivery to the Ak-Chin Indian Reservation from Federal land in the Vekol Valley, Waterman Wash area, and Bosque area in south-central Arizona. Withdrawal of 85,000 acre-feet per year as required by the Ak-Chin water-supply act--Public Law 95-328--will greatly deplete the amount of water in storage and may cause land subsidence in the areas. Study concurrent with well-field development will enable design changes to minimize pumping costs , water-level declines, movement of poor-quality water into the well fields, and potential land subsidence and associated earth fissures. Surface and bore-hole geophysical testing, aquifer tests, and the development of simulative mathematical models will accomplish these goals and permit quantitative evaluations of the potential deleterious effects resulting from development of the water supply.

    Objective The causes of low back pain in China and Western countries are extremely different. We attempted to analyze the risk factors of low back pain in urban and rural patients under the dual economy with the simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ) to demonstrate that SC-RMDQ could evaluate patients with low back pain arising from different causes. Methods Roland-Morris disability questionnaire was translated into SCRMDQ according to international guidelines for questionnaire adaptation. In this study, causes of low back pain of 187 outpatients and inpatients (99 urban patients and 88 rural patients) were analyzed. All patients underwent simplified Chinese version of Roland-Morris disability questionnaire (SC-RMDQ), simplified Chinese Oswestry disability index (SCODI) and visual analogue scale (VAS). Reliability was tested using reproducibility (intraclass coefficient of correlation – ICC) and internal consistency (Cronbach's alpha). Validity was tested using Pearson correlation analysis. Results The leading causes for low back pain were sedentariness (38.4%) and vibration (18.1%) in urban patients and waist bending (48.9%) and spraining (25%) in rural patients. Although causes of low back pain in the two groups of population were completely different, SCRMDQ had high internal consistency (Cronbach's α value of 0.874 in urban patients and 0.883 in rural patients) and good reproducibility (ICC value of .952 in urban patients and 0.949 in rural patients, P<0.01). SCRMDQ also showed significant correlation with Simplified Chinese version of Oswestry disability index (SCODI) and visual analogue scale (VAS) in rural areas (SCRMDQ-SCODI r = 0.841; SCRMDQ -VAS: r = 0.685, P<0.01) and in urban areas (SCRMDQ-SCODI: r = 0.818, P<0.01; SCRMDQ –VAS: r = 0.666, P<0.01). Conclusions Although causes of low back pain are completely different in rural and urban patients, SCRMDQ has a good reliability and validity, which

    Objectives To explore growth data (height-for-age, weight-for-age and BMI-for-age) of children living in poor socioeconomic conditions in rural areas of Chin State, Burma/Myanmar; and to compare these data with the growth and development z-score (GDZ) values for school-aged children and adolescents, provided by the WHO. Setting A support and educational programme, run by the Swedish association Chin Development and Research Society (CDRS), was carried out among underprivileged school-aged children, unable to attend school without economic and practical support, living in villages and remote areas in Chin State. Participants Community leaders who were well familiar with the citizens in the community identified children in need of this support. Other community members could also suggest or apply for this. The sample includes all participating children in the CDRS programme at the time of the data collection in six townships. The children were placed in host families, close to a suitable school. Two samples with a total of 639 children from 144 villages and remote areas were obtained: 1. Children in the CDRS Chin Programme (CCP) (2007–2010) comprised 558 children: 50% girls and boys. 2. Children in the Chin Society (CCS) (2010) comprised 81 children: 44% girls and 56% boys. Primary outcome measures Growth data. Results All growth data from both groups deviated significantly from the WHO standard references (p≤0.001). The prevalence of stunting (height-for-age ≤–2SD) was 52% among girls and 68% among boys. High levels of wasting (weight-for-age ≤–2SD) were found among girls 29% and boys 36% aged 5–10 years. In addition, severe thinness (BMI-for-age ≤–2SD) was found among girls 31% and boys 44%, all results to be compared to the expected 2.27%. Conclusions Many more than expected—according to the WHO reference values—in CCP and CCS suffered from stunting, wasting and thinness. PMID:26787249

    The black-chinned tilapia Sarotherodon melanotheron is a marine teleost characterised by an extreme euryhalinity. However, beyond a certain threshold at very high salinity, the species exhibits impaired growth and precocious reproduction. In this study, the relationships between reproductive parameters, environmental salinity and condition factor were investigated in wild populations of this species that were sampled in two consecutive years (2003 and 2004) from three locations in Senegal with different salinities: Guiers lake (freshwater, 0 psu), Hann bay (seawater, 37 psu) and Saloum estuary (hypersaline water, 66–127 psu). The highest absolute fecundity and spawning weight were recorded in seawater by comparison to either freshwater or hypersaline water whereas the poorest condition factors were observed in the most saline sampling site. These results reflect higher resource allocation to the reproduction due to the lowest costs of adaptation to salinity in seawater (the natural environment of this species) rather than differences in food resources at sites and/or efficiency at foraging and prey availability. Fecundities, oocyte size as well as spawning weight were consistent from year to year. However, the relative fecundity in the Saloum estuary varied significantly between the dry and rainy raisons with higher values in the wet season, which seems to reflect seasonal variations in environmental salinity. Such a reproductive tactic of producing large amounts of eggs in the rainy season when the salinity in the estuary was lower, would give the fry a better chance at survival and therefore assures a high larval recruitment. An inverse correlation was found between relative fecundity and oocyte size at the two extreme salinity locations, indicating that S. melanotheron has different reproductive strategies in these ecosystems. The adaptive significance of these two reproductive modes is discussed in regard to the heavy osmotic constraint imposed by extreme

However, we find that either agent (Bob or Charlie) alone can obtain half the information about the sender's secret without collaboration with the other, which does not satisfy the security requirement of QSS. Moreover, the secret message sent by Alice in the second protocol can be eavesdropped on or its communication can be disturbed by the builder of quantum channels (Trent).

    In this study, the efficacy of two dysphagia interventions, the Chin Tuck against Resistance (CTAR) and Shaker exercises, were evaluated based on two principles in exercise science-muscle-specificity and training intensity. Both exercises were developed to strengthen the suprahyoid muscles, whose contractions facilitate the opening of the upper esophageal sphincter, thereby improving bolus transfer. Thirty-nine healthy adults performed two trials of both exercises in counter-balanced order. Surface electromyography (sEMG) recordings were simultaneously collected from suprahyoid muscle group and sternocleidomastoid muscle during the exercises. Converging results using sEMG amplitude analyses suggested that the CTAR was more specific in targeting the suprahyoid muscles than the Shaker exercise. Fatigue analyses on sEMG signals further indicated that the suprahyoid muscle group were equally or significantly fatigued (depending on metric), when participants carried out CTAR compared to the Shaker exercise. Importantly, unlike during Shaker exercise, the sternocleidomastoid muscles were significantly less activated and fatigued during CTAR. Lowering the chin against resistance is therefore sufficiently specific and intense to fatigue the suprahyoid muscles. PMID:26837612

    Summary Background We hypothesized that there would be a good response to relative beta training, applied to regulate the dynamics of brain function in a patient with benign partial epilepsy with Rolandic Spikes (BPERS), associated with neuropsychiatric deficits resembling the symptoms of attention deficit-hyperactivity disorder (ADHD). Case Report The patient, E.Z., age 9.3, was suffering from neuropsychiatric symptoms, cognitive dysfunction, especially attention deficits, and behavioral changes, rendering him unable to function independently in school and in many situations of everyday life. He was treated for epilepsy, but only slight progress was made. The patient took part in 20 sessions of relative beta training combined with behavioral training. We used standardized neuropsychological testing, as well as ERPs before the experiment and after the completion of the neurotherapy program. Neuropsychological testing at baseline showed multiple cognitive deficits. Over the course of neurotherapy, E.Z.’s verbal and non-verbal IQ increased significantly. His cognitive functions also improved, including immediate and delayed logical and visual recall on the WMS-III, maintaining attention on the WMS-III, and executive functions, but remained below norms. Physiologically, the patient showed substantial changes after neurotherapy, including fewer spikes and an increased P300 NOGO component. Conclusions The cognitive deficits characteristic for ADHD in a child with BPERS may be unresponsive to antiepileptic treatment, but are reversible after a carefully selected neurotherapy program, combined with antiepileptic treatment. Event Related Potentials (ERPs) in the GO/NOGO task can be used to assess functional brain changes induced by neurotherapeutical programs. PMID:23111748

    Polybrominated diphenyl ethers (PBDEs) have been gaining much visibility in environmental chemical studies due to their similarity to PCBs and growing reports of harmful effects. The fact that these contaminants have not yet undergone bans or restrictions on the global level underscores the need for data on their occurrence. In the present study, fat samples from 26 White-chinned Petrels (Procellaria aequinoctialis) and 3 Spectacled Petrels (P. conspicillata) collected dead ashore or as bycatch of longline fisheries in southern Brazil were analyzed to determine concentrations of seven congeners (IUPAC #28, 47, 99, 100, 153, 154 and 183). Concentrations of ΣPBDEs ranged from not detectable to 72.70 ng g(-1) (wet weight), comparatively lower than concentrations reported for seabird samples in northern hemisphere. The most detected congeners were 153, 154 and 183. This pattern is close to that previously reported for birds of the same group, but not those from the same region. PMID:24143957

    The influence of environmental factors on the abundance and temporal variation of benthic fauna resources was studied in the eutrophic Tha Chin estuary located in Samut Sakhon province. The objectives were to analyze the status of abundance and temporal variation of the benthic fauna and to clarify the impacts from environmental factors (water and sediment quality). Field surveys were conducted monthly from August 2007 to March 2008 at 11 sampling stations in the estuary. Based on freshwater runoff volumes, the high-, medium-, and low-loading periods were categorized to be from August to October 2007, November to December 2007, and January to March 2008, respectively. The benthic fauna resources were composed of 57 species in eight phyla. Annelids were the dominant species (with the maximum density being 19,885 individuals/m2), followed by the mollusks. Both densities decreased during the low-loading period in 2008. Water quality deteriorated during the high-loading period. Land-based wastewater discharges decreased the levels of salinity and dissolved oxygen but dramatically increased various nutrients. Consequently, the sediment quality deteriorated during the medium-loading period. Bottom deposits during this time depicted high accumulation of acid volatile sulfides (more than 0.76 mg/g dry weight). Analyzing the environmental relationships, deposit feeders (for example, Nereis sp. and Prionospio sp.) and a clam (Arcuatula sp.) showed potential as bio-indicators for environmental monitoring. The overall results revealed the importance of changes in the water and sediment qualities that had an influence on related benthic resources. The increase in the level of NH4(+)-N had a negative impact on the economic clam species, while the sedimentary TOM showed positive correlation (P < 0.05) with this increase. The succession of groups based on feeding behavior seemed to correspond with stress in eutrophication along the salinity gradient and in different estuarine

    This research was carried out in Tha Chin Watershed in the central part of Thailand with attempts to apply multidisciplinary knowledge for understanding ecosystem structure and response to anthropogenic pollution and natural impacts leading to a proposal for an appropriate zonation management approach for sustainable utilization of the area. Water quality status of the Tha Chin River and Estuary had been determined by analyzing ecological, hydrological, and coastal oceanographic information from recent field surveys (during March 2006 to November 2007) together with secondary data on irrigation, land utilization, and socio-economic status.Results indicated that the Tha Chin River and Estuary was eutrophic all year round. Almost 100% of the brackish to marine areas reflected strongly hypertrophic water condition during both dry and high-loading periods. High NH(4)(+) and PO(4)(3-) loads from surrounding agricultural land use, agro-industry, and community continuously flew into the aquatic environment. Deteriorated ecosystem was clearly observed by dramatically low DO levels (ca 1 mg/l) in riverine to coastal areas and Noctiluca and Ceratium red tide outbreaks occurred around tidal front closed to the estuary. Accordingly, fishery resources were significantly decreased. Some riverine benthic habitats became dominated by deposit-feeding worms e.g. Lumbriculus, Branchiura, and Tubifex, while estuarine benthic habitats reflected succession of polychaetes and small bivalves. Results on analysis on integrated ecosystem responses indicated that changing functions were significantly influenced by particulates and nutrients dynamics in the system.Based on the overall results, the Tha Chin River and Estuary should be divided into 4 zones (I: Upper freshwater zone; II: Middle freshwater zone; III Lower freshwater zone; and IV: Lowest brackish to marine zone) for further management schemes on water remediation. In this study, the importance of habitat morphology and water flow

    A major feature of the human cortex is its huge morphological variability. Although a comprehensive literature about the sulco-gyral pattern of the central region is available from post-mortem data, a reliable and reproducible characterization from in vivo data is still lacking. The aim of this study is to test the reliability of morphological criteria of the central region sulci used in post-mortem data, when applied to in vivo magnetic resonance imaging (MRI) data. Thirty right-handed healthy individuals were included in the study. Automated segmentation and three dimensional (3D) surface-based rendering were obtained from clinical 3D T1-weighted MRI. Two senior radiologists labeled the three sulci composing the central region (precentral [PreCS], central [CS] and postcentral [PostCS]) and analyzed their morphological variations using 47 standard criteria derived from Ono's atlas based on post-mortem data. For each criterion, inter-rater concordance and comparison with the occurrence frequency provided in Ono's atlas were estimated. Overall, the sulcal pattern criteria derived from MRI data were highly reproducible between the raters with a high mean inter-rater concordance in the three sulci (CS: κ = 0.92 in left hemisphere/κ = 0.91 in right hemisphere; PreCS: κ = 0.91/κ = 0.93; PostCS: κ = 0.84/0.79). Only a very limited number of sulcal criteria significantly differed between the in vivo and the post-mortem data (CS: 2 criteria in the left hemisphere/3 criteria in the right hemisphere; PreCS: 3 in the left and right hemispheres; PostCS: 3 in the left hemisphere and 5 in the right hemisphere). Our study provides a comprehensive description of qualitative sulcal patterns in the central region from in vivo clinical MRI with high agreement with previous post-mortem data. Such identification of reliable sulcal patterns of the central region visible with standard clinical MRI data paves the way for the detection of subtle variations of the central sulcation associated with variations of normal or pathological functioning.

Placing the detectors on the roofs of high school buildings will lower the cost by using the existing urban infrastructure (INTERNET, power supply, etc.), and can be a very efficient way of science popularisation by engaging high school students in the research program. 30 high schools in Łódź are already involved in the project. The project has recently obtained some financial support from the City Council of Łódź. The donation enabled us to start experimental work on detector construction details. A cycle of lectures and seminars devoted to different aspects of project realization (detector construction, on-line data acquisition system, C++ programming) has been organized for students at our Institute and at schools.

    We assessed language lateralization in 177 healthy 4- to 11-year-old children and adults and atypical asymmetries associated with unilateral epileptic foci in 18 children with benign epilepsy with centrotemporal spikes (BECTS). Dichotic listening results revealed two indices of immature functional asymmetry when the focus was left-sided (BECTS-L). First, children with BECTS-L did not show left hemisphere dominance for the processing of place of articulation, which was recorded in children with BECTS-R and control children. On the contrary, healthy children exhibited a gradual increase in left hemisphere dominance for place processing during childhood, which is consistent with the shift from global to finer-grained acoustic analysis predicted by the Developmental Weighting Shift model. Second, children with BECTS-L showed atypical left hemisphere involvement in the processing of the voiced value (+V), associated with a long acoustic event in French stop consonants, whereas right hemisphere dominance increased with age for +V processing in healthy children. BECTS-L, therefore, interferes with the development of left hemisphere dominance for specific phonological mechanisms. PMID:21470917

Detection points will be connected by INTERNET to the central server and their work will be synchronized by GPS. The main scientific goal of the project are studies of ultra high energy cosmic rays. Using existing town infrastructure (INTERNET, power supply, etc.) will significantly reduce the cost of the experiment. Engaging high school students in the research program should significantly increase their knowledge of science and modern technologies, and can be a very efficient way of science popularisation. We performed simulations of the projected network capabilities of registering Extensive Air Showers and reconstructing energies of primary particles. Results of the simulations and the current status of project realisation will be presented.

    Although benign forms of epilepsies with onset in infancy have recently been recognized, the occurrence of seizures in an infant or very young child is very often an event of great significance and the prognosis concerning both epilepsy and neuropsychological development must be guarded. No reliable clinical or electroencephalographic (EEG) markers that can predict the outcome have been described. In a retrospective series of 10 patients, we found a peculiar EEG pattern seen across sleep stages, but not in the waking state in infants whose first seizures appeared before the age of 1 year, and which were mostly complex focal. In all cases, follow-up showed a favourable outcome with complete seizure remission and no cognitive impairment. The specificity of these EEG changes was 100%, but the sensitivity was lower, since they were not seen in some of the infants with the same favourable outcome. We discuss the clinical similarities between our patients and those cases reported earlier by other authors as benign, non-familial or familial focal epilepsies, in whom, however, no interictal abnormalities had been seen on the EEG. Such EEG changes are probably specific to benign, self-limited, early onset focal epilepsies. PMID:11967175

    Background: Resorption of the alveolar ridge often leaves insufficient bone volume. Very few studies have investigated the quantity and quality of bone formation in humans, following alveolar ridge augmentation, using autogenous bone and bovine bone mineral (BBM) under titanium mesh. Materials and Methods: Sixteen alveolar bone defects divided into two groups; control group with symphyseal autogenous bone covered by titanium mesh; and test group with symphyseal autogenous bone mixed with BBM in 1: 1 ratio and covered by titanium mesh. The outcomes were evaluated clinically, histologically, and histomorphometrically. Results: Clinical measurements showed that the horizontal bone gain was 3.44±0.54 mm and 2.88±0.57 mm, on average, for control group and test group, respectively. While graft absorption was 2.66±0.98 mm (43.62%) and 1.67±1.00 mm (36.65%), on average, for control group and test group, respectively. In the test group, BBM particles were still recognizable, on histologic analysis. They were surrounded completely or partly by newly formed bone. Clear signs of resorption of the BBM were found, with osteoclast cell noticed in the area. Histomorphometrically, the newly formed bone was 78.40%±13.97% and 65.58%±6.59%, whereas connective tissue constituted 21.60%±13.97% and 23.87%±4.79% for control group and test group, respectively. The remaining BBM particles occupied 10.55%±1.80%. All differences between the control and test groups were not significant (P>.05). Conclusion: This investigation suggests that horizonal ridge augmentation with titanium mesh and autogenous bone alone or mixed with BBM are predictable and ridges were augmented even if mesh exposure occurs.

    Cosmogenic dating, using in-situ 26A1 and 10Be in quartz pebbles from alluvial terrace surfaces, constrains the late Holocene slip rate on the Xidatan segment of the Kuniun fault in northeastern Tibet. Two terrace risers offset by 24 ± 3 and 33 f± 4m, having respective ages of 1788 ± 388 and 2914 ± 471 yr, imply a slip rate of 12.1 ± 2.6 mm/yr. The full range of ages obtained ((less than or equal to) 22.8 k.y., most of them between 6.7 and 1.4 k.y.) confirm that terrace deposition and incision, hence landform evolution, are modulated by post-glacial climate change. Coupled with minimum offsets of 9-12 m, this slip rate implies that great earthquakes (M-8) with a recurrence time of 800-1000 yr. rupture the Kunlun fault n

    HIV infection is a global disease that disproportionately burdens populations with nutritional vulnerabilities. Laboratory experiments have shown that selenium has an inhibitory effect on HIV in vitro through antioxidant effects of glutathione peroxidase and other selenoproteins. Numerous studies have reported low selenium status in HIV-infected individuals, and serum selenium concentration declines with disease progression. Some cohort studies have shown an association between selenium deficiency and progression to AIDS or mortality. In several randomized controlled trials, selenium supplementation has reduced hospitalizations, diarrheal morbidity, and improved CD4 cell counts, but the evidence remains mixed. Additional trials are recommended to study the effect of selenium supplementation on opportunistic infections, and other HIV disease related comorbidities in the context of highly active antiretroviral therapy in both developing and developed countries.

    The purpose of this study was to develop and validate a new chin template system for a two-piece narrowing genioplasty. Nine patients with wide chin deformities were enrolled. Surgeries were planned with the computer-aided surgical simulation (CASS) planning method. Surgical splints and chin templates were designed in a computer and fabricated using a three-dimensional printing technique. The chin template system included a cutting guide and a repositioning guide for a two-piece narrowing genioplasty. These guides were also designed to avoid the mental foramen area and inferior alveolar nerve loops during the osteotomy, for nerve protection. After surgery, the outcome evaluation was completed by first superimposing the postoperative computed tomography model onto the planned model, and then measuring the differences between the planned and actual outcomes. All surgeries were completed successfully using the chin template system. No inferior alveolar nerve damage was seen in this study. With the use of the chin templates, the largest linear root mean square deviation (RMSD) between the planned and the postoperative chin segments was 0.7mm and the largest angular RMSD was 4.5°. The results showed that the chin template system provides a reliable method of transfer for two-piece osseous narrowing genioplasty planning. PMID:26725914

    The question of interaction between ongoing neuronal activity and evoked responses has been addressed for different species, sensory systems and measurement modalities. Among other findings, there is converging evidence for an interaction of occipital alpha-rhythm amplitude with the visual evoked potential. Here, we test the hypothesis that the modulatory role of an ongoing rhythm might not be confined to the visual system and the occipital alpha rhythm, but instead may be generalized to other sensory systems. Using an online EEG analysis approach, we investigated the influence of the Rolandic alpha-rhythm on the somatosensory evoked potential (SEP). We triggered vibrotactile stimulation during periods of high Rolandic alpha-rhythm amplitude. Analysis revealed significant effects of pre-stimulus Rolandic alpha amplitude on the amplitude of the N140 and P260 components of the SEP, known to be linked to cognitive processing, but not on early sensory components. The N140-P260 complex shows a different focus in topography than the early sensory components and the pre-stimulus Rolandic alpha rhythm. These results indicate an involvement of Rolandic alpha-rhythm in higher cognitive processing. In more general terms--and in the context of similar studies in the visual system--our findings suggest that modulation of late EP components by ongoing rhythms might be a characteristic and possibly universal feature of sensory systems.

    PubMed

    Abadi, Mohammad; Pour, Omid Barahmand

    2015-10-01

    With increasing aesthetic awareness, in addition to the forehead, nose, and cheekbone prominence, the chin nowadays is seen as one of the most important parts of the facial skeleton. The size and location of these areas of the skeleton in relation to the skull base and their three-dimensional positional relationship to each other are essential and contribute the individuality of a human face. The position of the chin has a strong influence on the assessment of the facial harmony; its different types and forms dominate the appearance. Furthermore, the expression of the chin is equated with character traits and thus it is an important component of the profile forms. Genioplasty is a routine procedure for the correction of aesthetic and functional deformity of the chin region. It is therefore one of the contour-enhancing surgical methods. PMID:26579866

  4. The role of the right hemisphere in the control of speech prosody in propositional and affective contexts.

    PubMed

    Shapiro, B E; Danly, M

    1985-05-01

    Sixteen right-handed adult males with localized insult to either the right or left hemisphere and five control subjects without brain damage read aloud target sentences embedded in paragraphs, while intoning their voices in either a declarative, interrogative, happy, or sad mode. Acoustical analysis of the speech wave was performed. Right-anterior (pre-Rolandic) and right-central (pre- and post-Rolandic) brain-damaged patients spoke with less pitch variation and restricted intonational range across emotional and nonemotional domains, while patients with right posterior (post-Rolandic) damage had exaggerated pitch variation and intonational range across both domains. No such deficits were found in patients with left posterior damage, whose prosody was similar to that of normal control subjects. It is suggested that damage to the right hemisphere alone may result in a primary disturbance of speech prosody that may be independent of the disturbances in affect often noted in right-brain-damaged populations. PMID:4027566

  5. Dynamic Opposition of Clustered Proteins Stabilizes Cortical Polarity in the C. elegans Zygote.

    PubMed

    Sailer, Anne; Anneken, Alexander; Li, Younan; Lee, Sam; Munro, Edwin

    2015-10-12

    Dynamic maintenance of cell polarity is essential for development and physiology. Here we combine experiments and modeling to elucidate mechanisms that maintain cortical polarity in the C. elegans zygote. We show that polarity is dynamically stabilized by two coupled cross-inhibitory feedback loops: one involves the oligomeric scaffold PAR-3 and the kinase PAR-1, and the other involves CDC-42 and its putative GAP CHIN-1. PAR-3 and CDC-42 are both required locally to recruit PAR-6/PKC-3, which inhibits PAR-1 (shown previously) and inhibits local growth/accumulation of CHIN-1 clusters. Conversely, PAR-1 inhibits local accumulation of PAR-3 oligomers, while CHIN-1 inhibits CDC-42 (shown previously), such that either PAR-1 or CHIN-1 can prevent recruitment of PAR-6/PKC-3, but loss of both causes complete loss of polarity. Ultrasensitive dependence of CHIN-1 cluster growth on PAR-6/PKC-3 endows this core circuit with bistable dynamics, while transport of CHIN-1 clusters by cortical flow can stabilize the AP boundary against diffusive spread of PAR-6/PKC-3.

  10. Constructing an Ethical Writer for the Postmodern Scene.

    ERIC Educational Resources Information Center

    Hassett, Michael J.

    The advent of postmodern criticism has brought about numerous changes in the way those in the academy read and teach the reading of texts. From Michel Foucault's "What is an Author?" to Roland Barthes'"The Death of the Author" and beyond, critics and theorists have sought to decrease the author-ity of the material that is read. In doing so, these…

    Tick-borne encephalitis virus (TBEV) represents one of the most dangerous human pathogens circulating in Europe and East Asia. No effective treatment for TBEV infection currently exists, and vaccination is the primary preventive measure. Although several inactivated vaccines have been licensed, the development of novel vaccines against TBEV remains a high priority in disease-endemic countries. In the present study, a live chimeric recombinant TBEV (ChinTBEV) was created by substituting the major structural genes of TBEV for the corresponding regions of Japanese encephalitis virus (JEV) live vaccine strain SA14-14-2. The resulting chimera had a small-plaque phenotype, replicated efficiently in both mammalian and mosquito cells. The preliminary data from in vitro passaging indicated the potential for stability of ChinTBEV. ChinTBEV also exhibited significantly attenuated neuroinvasiveness in mice upon either intraperitoneal or subcutaneous inoculation in comparison with its parental TBEV. Importantly, a single immunisation with ChinTBEV elicited TBEV-specific IgG and neutralising antibody responses in a dose-dependent manner, providing significant protection against lethal TBEV challenge in mice. Taken together, the results of this proof-of-concept study indicate that ChinTBEV can be further developed as a potential vaccine candidate against TBEV infection. Moreover, the construction of this type of flavivirus chimera using a JEV vaccine strain as the genetic backbone represents a universal vaccine approach. PMID:24394443

    The purpose of this study was to evaluate the results of osseous genioplasty with bimaxillary orthognathic surgery. A retrospective consecutive case series of patients treated by a single surgeon between 2004 and 2013 was studied. All underwent Le Fort I, sagittal ramus osteotomies, septoplasty, inferior turbinate reduction, and osseous genioplasty. The outcome variables included the presenting chin dysmorphology, complications, and assessment of morphologic change. A Steiner analysis was completed for each subject's interval cephalogram. Two hundred sixty-two subjects met the inclusion criteria. Their mean age at operation was 25 (range 13-63) years. Chin osteotomy complications included one wound infection (0.4%), and two of the 1572 mandibular anterior teeth at risk sustained a pulpal injury. None of the subjects required revision. For subjects undergoing chin advancement, the mean change was +3.5 (range +3 to +6) mm. A majority also underwent counterclockwise rotation of the mandible (62%). For those undergoing chin lengthening, the mean change was +5 (range +3 to +12mm) mm, and for those undergoing vertical shortening, the mean change was -3.5 (range -3 to -7) mm. Osseous genioplasty is confirmed to be a safe method to reshape the chin. When osseous genioplasty is performed in conjunction with bimaxillary orthognathic surgery, only a modest horizontal change is required to achieve the preferred pogonion projection. PMID:26972157

    Recent advances[1] in factorizing the classical and quantum evolution operator to fourth order with purely positive coefficients have produce a new class of Monte Carlo[2,3] and quantum dynamical algorithms[4,5] that are at least two orders of magnitude better than existing algorithms of comparble order. This talk will focus on solving the Schrodinger equation in real and imaginary time for the extraction of dynamical information and for the determination of eigenvalue-function pairs from large 3-D grids.

    Many different materials are available for augmentation mentoplasty. However, the optimal implant material for chin implantation has yet to be found. During the past several years, a number of experienced surgeons have turned to the use of Mersilene mesh. Mersilene mesh is a non-absorbable Dacron polyester fiber that can be conformed easily into layers to achieve tailored dimensions and shape. At the McCollough Plastic Surgery Clinic PA, Birmingham, Ala, 277 patients over a 10-year period underwent chin augmentation with Mersilene mesh implants. The material provides excellent tensile strength, durability, and surgical adaptability. The overall complication rate was 3.2% (nine patients); infection rate, 2.5% (seven patients); and removal secondary to infection, 1.7% (five patients). Based on this 10-year experience, Mersilene mesh remains our material of choice for chin augmentation. PMID:2206500

    Purpose. To compare errors in digital panoramic radiographs of permanent and mixed dentitions. Methods. 143 and 146 digital radiographs of mixed and permanent dentitions were examined. Results. Significantly fewer errors presented in the mixed dentition. Positioning too forward significantly prevalent in the mixed dentition; slumped position and nonpositioning of chin properly were significantly prevailed in the permanent dentition. Blurred or shortened upper incisors were significantly more prevalent in the mixed dentition. Diagnostic ability could be improved by manipulating the brightness or contrast in nearly 45% of all radiographs. In the mixed dentition, tilting the chin down and a slumped position made the lower incisors significantly nondiagnostic. In the permanent dentition, tilting the chin down made the lower incisors to be significantly nondiagnostic. Conclusions. More errors were prevalent in panoramic radiographs of permanent dentitions. Properly positioning the patient is the most important factor in preventing a cascade of errors. PMID:22505905

    Introduction To evaluate, using cone-beam computed tomography (CBCT), both the condylar-fossa relationships and the mandibular and condylar asymmetries between unilateral cleft lip and palate (UCLP) patients and non-cleft patients with class III skeletal relationship, and to investigate the factors of asymmetry contributing to chin deviation. Methods The UCLP and non-cleft groups consisted of 30 and 40 subjects, respectively, in mixed dentition with class III skeletal relationships. Condylar-fossa relationships and the dimensional and positional asymmetries of the condyles and mandibles were examined using CBCT. Intra-group differences were compared between two sides in both groups using a paired t-test. Furthermore, correlations between each measurement and chin deviation were assessed. Results It was observed that 90% of UCLP and 67.5% of non-cleft subjects had both condyles centered, and no significant asymmetry was found. The axial angle and the condylar center distances to the midsagittal plane were significantly greater on the cleft side than on the non-cleft side (P=0.001 and P=0.028, respectively) and were positively correlated with chin deviation in the UCLP group. Except for a larger gonial angle on the cleft side, the two groups presented with consistent asymmetries showing shorter mandibular bodies and total mandibular lengths on the cleft (deviated) side. The average chin deviation was 1.63 mm to the cleft side, and the average absolute chin deviation was significantly greater in the UCLP group than in the non-cleft group (P=0.037). Conclusion Compared with non-cleft subjects with similar class III skeletal relationships, the subjects with UCLP showed more severe lower facial asymmetry. The subjects with UCLP presented with more asymmetrical positions and rotations of the condyles on axial slices, which were positively correlated with chin deviation. PMID:26237311

    The development of a safe and efficient dengue vaccine represents a global challenge in public health. Chimeric dengue viruses (DENV) based on an attenuated flavivirus have been well developed as vaccine candidates by using reverse genetics. In this study, based on the full-length infectious cDNA clone of the well-known Japanese encephalitis virus live vaccine strain SA14-14-2 as a backbone, a novel chimeric dengue virus (named ChinDENV) was rationally designed and constructed by replacement with the premembrane and envelope genes of dengue 2 virus. The recovered chimeric virus showed growth and plaque properties similar to those of the parental DENV in mammalian and mosquito cells. ChinDENV was highly attenuated in mice, and no viremia was induced in rhesus monkeys upon subcutaneous inoculation. ChinDENV retained its genetic stability and attenuation phenotype after serial 15 passages in cultured cells. A single immunization with various doses of ChinDENV elicited strong neutralizing antibodies in a dose-dependent manner. When vaccinated monkeys were challenged with wild-type DENV, all animals except one that received the lower dose were protected against the development of viremia. Furthermore, immunization with ChinDENV conferred efficient cross protection against lethal JEV challenge in mice in association with robust cellular immunity induced by the replicating nonstructural proteins. Taken together, the results of this preclinical study well demonstrate the great potential of ChinDENV for further development as a dengue vaccine candidate, and this kind of chimeric flavivirus based on JE vaccine virus represents a powerful tool to deliver foreign antigens.

    This paper proposes a protocol for multi-party quantum secret sharing utilizing four non-orthogonal two-particle entangled states following some ideas in the schemes proposed by Liu et al. (2006 Chin. Phys. Lett. 23 3148) and Zhang et al. (2009 Chin. Phys. B 18 2149) respectively. The theoretical efficiency for qubits of the new protocol is improved from 50% to approaching 100%. All the entangled states can be used for generating the private key except those used for the eavesdropping check. The validity of a probable attack called opaque cheat attack to this kind of protocols is considered in the paper for the first time.

    Duck Tembusu virus (DTMUV), a newly identified flavivirus, has rapidly spread to China, Malaysia and Thailand. The potential threats to public health have been well-highlighted; however its virulence and pathogenesis remain largely unknown. Here, by using reverse genetics, a recombinant chimeric DTMUV based on Japanese encephalitis live vaccine strain SA14-14-2 was obtained by substituting the corresponding prM and E genes (named ChinDTMUV). In vitro characterization demonstrated that ChinDTMUV replicated efficiently in mammalian cells with small-plaque phenotype in comparison with its parental viruses. Mouse tests showed ChinDTMUV exhibited avirulent phenotype in terms of neuroinvasiveness, while it retained neurovirulence from its parental virus DTMUV. Furthermore, immunization with ChinDTMUV was evidenced to elicit robust IgG and neutralizing antibody responses in mice. Overall, we successfully developed a viable chimeric DTMUV, and these results provide a useful platform for further investigation of the pathogenesis of DTMUV and development of a live attenuated DTMUV vaccine candidate.

    Purpose Panoramic radiographs taken using conventional chin-support devices have often presented problems with positioning accuracy and reproducibility. The aim of this report was to propose a new bite block for panoramic radiographs of anterior edentulous patients that better addresses these two issues. Materials and Methods A new panoramic radiography bite block similar to the bite block for dentulous patients was developed to enable proper positioning stability for edentulous patients. The new bite block was designed and implemented in light of previous studies. The height of the new bite block was 18 mm and to compensate for the horizontal edentulous space, its horizontal width was 7 mm. The panoramic radiographs using the new bite block were compared with those using the conventional chin-support device. Results Panoramic radiographs taken with the new bite block showed better stability and bilateral symmetry than those taken with the conventional chin-support device. Patients also showed less movement and more stable positioning during panoramic radiography with the new bite block. Conclusion Conventional errors in panoramic radiographs of edentulous patients could be caused by unreliability of the chin-support device. The newly proposed bite block for panoramic radiographs of edentulous patients showed better reliability. Further study is required to evaluate the image quality and reproducibility of images with the new bite block. PMID:26125007

    2014-01-01

    Two new species of Hymenocephalus are described from the New Zealand region and Tasman Sea. Hymenocephalus fuscus sp. n. has 11-12 pelvic fin rays, is darkly pigmented, with enlarged bony ridges on the dorsal aspects of head, lacks a chin barbel, has few (16-19) gill rakers on inner side of first arch and is similar to other species in the H. aterrimus species group. Hymenocephalus maculicaudus sp. n. has 8 pelvic fin rays, a mid-lateral line of melanophores on body and tail that extends about a head length posterior to anal fin origin, a short (7-16 % HL) chin barbel and is similar to other species in the H. megalops species group. Hymenocephalus nascens has 12-14 pelvic fin rays, lacks a chin barbel, has a mid-lateral stripe of silvery (fresh) or brownish (preserved) pigment running along trunk and tail. Hymenogadus gracilis has a serrated (weak, near tip) first dorsal fin spine, 7-9 pelvic fin rays, long (20-30% HL) chin barbel, and one row of enlarged melanophores along lateral mid-line of the tail. Hymenocephalus nascens and Hymenogadus gracilis are recorded for the first time from the New Zealand region. A key to the known New Zealand species of Hymenocephalus and Hymenogadus is provided.  PMID:25284648
