Factors influencing the frequency of rolandic spikes are rarely reported. We examined the influence of movement, tactile stimulation and cognitive test on the discharge rate of rolandic spikes. We studied 35 children with EEG rolandic spikes. Eighteen children had nonfebrile convulsions. Benign childhood epilepsy with centrotemporal spikes was diagnosed in 12 cases. Testing during the EEG included hand and tongue movements, cognitive tasks and tactile stimulation of face and hands. Rolandic spikes were counted by visual analysis in each phase of the test and the frequency expressed as mean number per min. During tongue movements there was a significantly lower discharge rate when compared to previous and subsequent rest phases. For the left hemisphere there was reduction in discharge rate during right hand movements and looking at colored spots but only when compared with the previous rest phase. The reduction in mean number of spikes/min by tongue movements occurred in patients with and without epilepsy. For patients with cerebral lesion the decrease in discharge rate during tongue movements was not significant whereas for those without cerebral lesion a significant reduction was evident. A decrease in the mean number of spikes/min of 50% or more was significantly more frequent among 29 patients without than among 6 patients with cerebral lesion. Our study showed the inhibition of rolandic spikes by tongue movements confirming the hypothesis that the localization of discharges is an important factor in determining its reactivity. The presence or not of cerebral lesion may be an important factor in the degree of reactivity.

2014-01-01

The aim of this study was to compare the profile changes after conventional and chin shield genioplasty. 20 patients with retruded chin were randomly allocated to two different groups. The experimental group had chin shield osteotomy with interposition of hydroxyapatite collagen graft soaked in platelet rich plasma, while the controls had a conventional genioplasty. The outcome variables evaluated were lip seal, chin thickness, mandibular base length, SNB, labiomental angle, anterior lower facial height, transverse chin shift, and complications. There was an increase in chin thickness among all, but a significant increase in anterior lower facial height was seen in the experimental group only. There was no statistically significant difference in satisfaction score in both groups. Chin shield genioplasty provides horizontal as well as vertical lengthening of chin without deepening of the mentolabial fold. Hydroxyapatite collagen bone graft and platelet rich plasma promote healing, induce bone formation and reduce bone resorption.

2014-10-01

Chin tuck has been has been widely used to prevent aspiration in the patients with dysphagia. This study was performed to investigate the effectiveness and the degree of optimal neck flexion of chin tuck. Ninety-seven patients who showed aspiration in the videofluoroscopic swallow study (VFSS). Participants were grouped into the effective (patients who showed effect with chin tuck) and ineffective group (those who did not show effect with chin tuck). VFSS was performed in neutral and chin tuck position and findings were compared between the groups. Severity of aspiration was assessed by the point penetration-aspiration scale. Duration of dysphagic symptoms, history of tracheostomy, and other possible contributing factors were also compared. Neck flexion angle was measured to find appropriate posture in which aspiration was prevented with chin tuck. Aspiration was reduced or eliminated in only 19 patients (19.6 %) with chin tuck. Oral transit time, pharyngeal delayed time and pharyngeal transit time were significantly shortened in both groups (p < 0.05), but the difference between the groups was not significant. Female sex and absence of residue in pyriform sinus favored the effect of chin tuck (p < 0.05). At least 17.5° of neck flexion was required to achieve an effect with chin tuck. The effectiveness of chin tuck was less than anticipated. Patients without residue in pyriform sinus were more likely to benefit from chin tuck. Sufficient neck flexion was important in chin tuck to prevent aspiration.

Mothers of neonatal intensive care unit (NICU) patients sometimes bring expressed milk that is blood tinged to the NICU. In certain instances, the blood contamination appears minimal, whereas in others, the milk is quite dark pink. We have observed inconsistencies in practice regarding whether or not to feed blood-tinged colostrum or milk to NICU patients. We know of no evidence that establishes best practice in this area, and thus we sought to determine attitudes of NICU professionals on which to base a potentially best practice. We conducted a web-based anonymous survey of attitudes of NICU professionals at Intermountain Healthcare regarding feeding blood-tinged expressed milk to NICU patients. These professionals included neonatologists, neonatal nurse practitioners, NICU nurses, NICU dieticians and lactation consultants. Survey results were returned from 64% (426 of 667) of those to whom it was sent. A total of 75% of respondents reported that their practice was NOT to feed the blood-tinged milk illustrated in the figure as sample 2, and nearly all respondents (98%) reported that they would NOT feed the milk illustrated as sample 3. The majority of the neonatologists (56%) and the lactation consultants (58%) recommended feeding moderately bloody milk (sample 2), whereas only 22% of the neonatal nurse practitioners (NNPs), NICU nurses and NICU dieticians recommended feeding such samples (<0.001). The most frequently selected reason for NOT feeding blood-tinged milk was that it would likely cause gastrointestinal upset and feeding intolerance (selected by 77%). The majority (87%) overestimated the amount of blood contaminating a milk sample (sample 3). As colostrum and human milk feedings can be of value to NICU patients, evidence should be assembled to document whether feeding blood-tinged samples indeed have the problems listed by the survey respondents. Such evidence is needed to enable informed decisions involving the benefits vs risks of feeding blood-tinged

Schild, A M; Fricke, J; Rüssmann, W; Neugebauer, A

2009-10-01

Kestenbaum surgery is performed for nystagmus-related abnormal head posture, and symmetrically changes the position of both eyes to shift the null point to the primary position. Most patients with infantile nystagmus have their null point zone in a lateral gaze position. Less frequently, surgery can be performed to reduce chin-up or chin-down head posture. We report indications for, and the results of eight consecutive interventions performed according to the Kestenbaum principle for the reduction of a chin-up or chin-down head posture. In a retrospective study, the clinical findings for eight patients who consecutively underwent treatment in the University Eye Hospital of Cologne between 2001 and 2007 were investigated. The patients were aged 6 to 16 years; median age was 6.5 years. For all patients, surgery was to correct a chin-up or chin-down head posture due to infantile nystagmus. Preoperatively, five patients showed a chin-down, three a chin-up head posture. All vertical rectus muscles were recessed or tucked between 6 and 7 mm; the resulting cyclodeviation was reduced by an intervention on the superior oblique muscles (6 to 8 mm tucking, in the case of chin-down, or recession in the case of chin-up head posture). Surgery was successful in seven of the eight patients, with a reduction of the vertical head posture to less than 10 degrees. In the cases of chin-down posture, head posture was reduced to between 0 degrees and a maximum of 20 degrees in one case postoperatively (before the operation 20 degrees to 35 degrees ); in the cases of chin-up posture, to less than 8 degrees (before the operation 25 degrees to 35 degrees). One case showed no postoperative improvement in chin-down posture but a head turn to the left of up to 20 degrees; another case had a remaining chin-up posture of 8 degrees with a right turn of 15 degrees . Binocular vision was better or the same in all cases after surgery. For nystagmus patients with chin-up or chin-down head posture

Reading comprehension difficulties in children with rolandic epilepsy.

PubMed

Currie, Nicola K; Lew, Adina R; Palmer, Tom M; Basu, Helen; De Goede, Christian; Iyer, Anand; Cain, Kate

2018-03-01

Difficulties in reading comprehension can arise from either word reading or listening comprehension difficulties, or a combination of the two. We sought to determine whether children with rolandic epilepsy had poor reading comprehension relative to typically developing comparison children, and whether such difficulties were associated with word reading and/or general language comprehension difficulties. In this cross-sectional study, children with rolandic epilepsy (n=25; 16 males, 9 females; mean age 9y 1mo, SD 1y 7mo) and a comparison group (n=39; 25 males, 14 females; mean age 9y 1mo, SD 1y 3mo) completed assessments of reading comprehension, listening comprehension, word/non-word reading, speech articulation, and Non-verbal IQ. Reading comprehension and word reading were worse in children with rolandic epilepsy (F 1,61 =6.89, p=0.011, ηp2=0.10 and F 1,61 =6.84, p=0.011, ηp2=0.10 respectively), with listening comprehension being marginal (F 1,61 =3.81, p=0.055, ηp2=0.06). Word reading and listening comprehension made large and independent contributions to reading comprehension, explaining 70% of the variance. Children with rolandic epilepsy may be at risk of reading comprehension difficulties. Thorough assessment of individual children is required to ascertain whether the difficulties lie with decoding text, or with general comprehension skills, or both. Children with rolandic epilepsy may be at risk of poor reading comprehension. This was related to poor word reading, poor listening comprehension, or both. Reading comprehension interventions should be tailored to the profile of difficulties. © 2017 Mac Keith Press.

Paraffin Granulomata, “Witch's Chin,” and Nasal Deformities

Field, Lawrence Marshall

2010-01-01

A 57-year-old Filipino woman had paraffin materials placed in her nose, chin, and cheeks approximately 15 years prior to consultation. Progressive enlargement of the chin had occurred, simulating a witch's chin deformity, with a lesser degree of the distal nose and columellar area. Restoration of a relatively normal chin contour was accomplished by using tumescent bi-level anesthesia, mobilizing the protuberant tissues, hemi-ressecting the excess skin, and sculpting the subjacent tissue to an appropriate degree. The nose was then entered at the columellar junction with the upper lip, an open rhinotomy was accomplished, the supra-cartilaginous fibrous tissue was serially ressected to reform the profile, the cartilage was replaced to narrow the nasal configuration, and the nose structure was then replaced. Cosmetic improvement was significant. PMID:20725553

This study was conducted to compare the mean preference scores for orthodontic treatment need, considering the chin position, amongst orthodontists, orthodontic patients and their parents. Male and female profile silhouettes were prepared by changing their chin prominence using Adobe Photoshop 7 with zero degree meridian as line of reference. Rating of these silhouettes was done by the three groups of raters (orthodontists, orthodontic patients and their parents) on a scale of four with one being no need of treatment and four being severe need of treatment. There was a statistically significant difference seen amongst orthodontists and the orthodontic patients and also amongst the orthodontist and the orthodontic patient's parents for the 2mm and 4mm chin position with orthodontists scoring a higher need of treatment as compared to the patients and parents.

Tongue contractions during speech may have led to the development of the bony geometry of the chin following the evolution of human language: a mechanobiological hypothesis for the development of the human chin.

PubMed

Ichim, Ionut; Kieser, Jules; Swain, Michael

2007-01-01

One of the most fundamental yet unanswered questions of human evolution is that of the development of the chin. Whereas it is known that the chin, or mentum osseum, is an unique anatomical feature of modern humans that emerged during the Middle and Late Pleistocene, its origin and biomechanical significance are the subjects of intense controversy. Theories range from the suggestion that the chin evolved as a result of progressive reduction of the dental arch, which left it as a protrusion, to the hypothesis that it provided resistance to mandibular bending during mastication. Until now however, no accepted functional explanation of the human chin has emerged. Here, we develop the hypothesis that the actions of the tongue and non-masticatory orofacial muscles may have played a significant role on the development of the human chin. We report numerical simulations of the forces and resultant stresses developed in hypothetical chinned and non-chinned mandibles. Using empirical data and estimates of the forces generated by the human tongue during speech, our hypothesis suggests that the chin might in fact have developed as a result of the actions of the tongue and perioral muscles, rather than as a buttress to withstand masticatory induced stress. This provides a new perspective on the generation of the chin and importantly, suggests that its appearance may be causally related to the development of the human language.

Numb chin syndrome is characterized by anaesthesia or paraesthesia in the areas supplied by the chin nerve. It is a rare symptom which tends to be underestimated. Far from being insignificant, it should be taken as an indication of hidden malignant disease. In patients previously diagnosed with neoplasia, it is frequently associated with ominous diagnosis indicating rapid progression of the disease. This paper reports the case of a patient diagnosed with breast cancer 20 years earlier who presents chin numbness. Further tests confirm the suspicion of metastatic disease (meningeal carcinomatosis and multiple bone and pulmonary metastases) leading to death two months after the initial consultation.

A validated scale is needed for objective and reproducible comparisons of chin appearance before and after chin augmentation in practice and clinical studies. To describe the development and validation of the 5-point photonumeric Allergan Chin Retrusion Scale. The Allergan Chin Retrusion Scale was developed to include an assessment guide, verbal descriptors, morphed images, and real subject images for each scale grade. The clinical significance of a 1-point score difference was evaluated in a review of multiple image pairs representing varying differences in severity. Interrater and intrarater reliability was evaluated in a live-subject validation study (N = 298) completed during 2 sessions occurring 3 weeks apart. A difference of ≥1 point on the scale was shown to reflect a clinically meaningful difference (mean [95% confidence interval] absolute score difference, 1.07 [0.94-1.20] for clinically different image pairs and 0.51 [0.39-0.63] for not clinically different pairs). Intrarater agreement between the 2 live-subject validation sessions was substantial (mean weighted kappa = 0.79). Interrater agreement was substantial during the second rating session (0.68, primary end point). The Allergan Chin Retrusion Scale is a validated and reliable scale for physician rating of severity of chin retrusion.

The influence of lower lip position on the perceived attractiveness of chin prominence.

2013-09-01

To evaluate the influence of the lower lip prominence for varying degrees of chin prominence in the sagittal plane and to establish whether lower lip prominence affects the perceived desire for surgery. To assess differences in preference between orthodontists and laypeople as well as the effect of age, gender, and ethnicity of observers on perceptions of attractiveness and desire for surgery. A silhouette of an idealized profile image was created. The image was manipulated to create six images demonstrating different degrees of retrogenia and progenia altered in 4-mm increments from -12 mm to +12 mm and six images demonstrating chin and lower lip prominence in 4-mm increments from -12 mm to +12 mm. One hundred laypeople and 30 orthodontists ranked the images from the most to the least attractive. A duplicate of one of the images was used in order to assess intraexaminer reliability. The amount and direction of sagittal chin position and the prominence of the lower lip were found to have a significant effect on image rank. Chin protrusion was less attractive than retrusion and surgery was desired more often for these images. The overall direction of opinion was the same for laypeople and orthodontists. The chin prominence observed in a progenic patient is deemed less attractive than the combined chin and lower lip prominence observed in a patient with mandibular prognathism. In profiles with a more prominent chin a more protrusive lower lip position was preferred. When the chin was retrusive, a normal lower lip position was preferred to a retrusive lip.

To assess the wavelet entropy for the characterization of intrinsic aberrant temporal irregularities in the time series of resting-state blood-oxygen-level-dependent (BOLD) signal fluctuations. Further, to evaluate the temporal irregularities (disorder/order) on a voxel-by-voxel basis in the brains of children with Rolandic epilepsy. The BOLD time series was decomposed using the discrete wavelet transform and the wavelet entropy was calculated. Using a model time series consisting of multiple harmonics and nonstationary components, the wavelet entropy was compared with Shannon and spectral (Fourier-based) entropy. As an application, the wavelet entropy in 22 children with Rolandic epilepsy was compared to 22 age-matched healthy controls. The images were obtained by performing resting-state functional magnetic resonance imaging (fMRI) using a 3T system, an 8-element receive-only head coil, and an echo planar imaging pulse sequence ( T2*-weighted). The wavelet entropy was also compared to spectral entropy, regional homogeneity, and Shannon entropy. Wavelet entropy was found to identify the nonstationary components of the model time series. In Rolandic epilepsy patients, a significantly elevated wavelet entropy was observed relative to controls for the whole cerebrum (P = 0.03). Spectral entropy (P = 0.41), regional homogeneity (P = 0.52), and Shannon entropy (P = 0.32) did not reveal significant differences. The wavelet entropy measure appeared more sensitive to detect abnormalities in cerebral fluctuations represented by nonstationary effects in the BOLD time series than more conventional measures. This effect was observed in the model time series as well as in Rolandic epilepsy. These observations suggest that the brains of children with Rolandic epilepsy exhibit stronger nonstationary temporal signal fluctuations than controls. 2 Technical Efficacy: Stage 3 J. Magn. Reson.

2015-01-01

Objective The effects of the chin-tuck maneuver, a technique commonly employed to compensate for dysphagia, on cervical auscultation are not fully understood. Characterizing a technique that is known to affect swallowing function is an important step on the way to developing a new instrumentation-based swallowing screening tool. Methods In this study, we recorded data from 55 adult participants who each completed five saliva swallows in a chin-tuck position. The resulting data was processed using previously designed filtering and segmentation algorithms. We then calculated 9 time, frequency, and time-frequency domain features for each independent signal. Results We found that multiple frequency and time domain features varied significantly between male and female subjects as well as between swallowing sounds and vibrations. However, our analysis showed that participant age did not play a significant role on the values of the extracted features. Finally, we found that various frequency features corresponding to swallowing vibrations did demonstrate statistically significant variation between the neutral and chin-tuck positions but sounds showed no changes between these two positions. Conclusion The chin-tuck maneuver affects many facets of swallowing vibrations and sounds and its effects can be monitored via cervical auscultation. Significance These results suggest that a subject’s swallowing technique does need to be accounted for when monitoring their performance with cervical auscultation based instrumentation.

The ontogeny of the chin: an analysis of allometric and biomechanical scaling

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.

In a previous study we demonstrated children with Benign Rolandic Epilepsy have normal intelligence and language ability. However, difficulties in verbal and visual memory and aspects of phonological awareness were found compared to normative data. To address the methodological limitations related to the use of normative data, we compared the same cohort of children with Benign Rolandic Epilepsy to a matched control group. Controls (n=40) matched on age and gender to the Benign Rolandic Epilepsy cohort underwent neuropsychological assessment. The life functioning of the control group was assessed using a modified version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The study confirmed the previous findings of memory and phonological awareness difficulties. In addition, the children with Benign Rolandic Epilepsy had significantly lower IQ scores than the matched control group. Paired sample t-tests showed that on 8 of 11 QOLCE scales, children with Benign Rolandic Epilepsy were rated by parents as having poorer life functioning compared to matched controls, including lower parental ratings on the subscales of memory and language. Benign Rolandic Epilepsy has an excellent seizure prognosis, but this study further emphasizes potential cognitive difficulties. Using an age and gender matched control group, the previous findings of memory and phonological awareness difficulties were validated. These problems in cognition were also identified by parents of children with Benign Rolandic Epilepsy as problematic and impacting upon the child's quality of life.

Fine motor skills in children with rolandic epilepsy.

This study aimed to evaluate fine motor skills in children with rolandic epilepsy (RE). The research included 44 children diagnosed with typical RE and 44 controls matched in terms of age, gender, and level of education. Fine motor skills were evaluated with the Purdue Pegboard Test, and intelligence was measured with the Wechsler Intelligence Scale for Children. After controlling for the effect of intelligence on fine motor skills, the results showed that the children with RE did not perform as well as the controls in the PPT dominant hand, both hands, and assembly subtests. Epileptic focus, treatment status, type of antiepileptic treatment, age at the time of the first seizure, time since the last seizure, and total number of seizures did not affect motor skills. Rolandic epilepsy negatively affected fine motor skills regardless of the children's level of intelligence. © 2013.

Salemann, V.

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.

Precise soft-to-hard tissue ratios in orthofacial chin procedures are not well established. The aim of this study was to determine useful soft-to-hard tissue ratios for planning the magnitude of sliding genioplasty (chin osteotomy), osseous chin recontouring and alloplastic chin augmentation. A systematic review of English and non-English articles using PubMed central, ProQuest Dissertations and Theses, Science Citation Index, Elsevier Science Direct Complete, Highwire Press, Springer Standard Collection, SAGE premier 2011, DOAJ Directory of Open Access Journals, Sweetswise, Free E-Journals, Ovid Lippincott Williams & Wilkins total Access Collection, Wiley Online Library Journals, and Cochrane Plus databases from their onset until July 2014. Additional studies were identified by searching the references. Search terms included soft tissue, ratios, genioplasty, mentoplasty, chin, genial AND advancement, augmentation, setback, retrusion, impaction, reduction, vertical deficit, widening, narrowing, and expansion. Study selection criteria were as follows: only academic publications; human patients; no reviews; systematic reviews or meta-analyses; no cadavers; no syndromic patients; no pathology at the chin or mandible region; only articles of level of evidence from I to IV; number of patients must be cited in the articles; hard-to-soft tissue ratios must be cited in the articles or at least are able to be calculated with the quantitative data available in the article; if all patients of one article have had bilateral sagittal split osteotomy (BSSO) performed along with chin osteotomy, there should be an independent group evaluation of the data concerning to the chin; and no restriction regarding the size of the group. Independent extraction of articles by two authors using predefined data fields, including study quality indicators (level of evidence). The search identified 22 articles. Eleven additional articles were found in their reference sections. Of these, two were

Retrospective design. To compare the responsiveness and test-retest reliability of the Functional Rating Index and the 18-item version of the Roland-Morris Disability Questionnaire in detecting change in disability in patients with work-related low back pain. Many low back pain-specific disability questionnaires are available, including the Functional Rating Index and the 18-item version of the Roland-Morris Disability Questionnaire. No previous study has compared the responsiveness and reliability of these questionnaires. Files of patients who had been treated for work-related low back pain at a physical therapy clinic were reviewed, and those containing initial and follow-up Functional Rating Index and 18-item Roland-Morris Disability Questionnaires were selected. The responsiveness of both questionnaires was compared using two different methods. First, using the assumption that patients receiving treatment improve over time, various responsiveness coefficients were calculated. Second, using change in work status as an external criterion to identify improved and nonimproved patients, Spearman's rho and receiver operating characteristic curves were calculated. Reliability was estimated from the subset of patients who reported no change in their condition over this period and expressed with the intraclass correlation coefficient and the minimal detectable change. One hundred and forty-three patient files were retrieved. The responsiveness coefficients for the Functional Rating Index were greater than for the 18-item Roland-Morris Disability Questionnaire. The intraclass correlation coefficient values for both questionnaires calculated from 96 patient files were similar, but the minimal detectable change for the Functional Rating Index was less than for the 18-item Roland-Morris Disability Questionnaire. The Functional Rating Index seems preferable to the 18-item Roland-Morris Disability Questionnaire for use in clinical trials and clinical practice.

This article reports the dual function of a double-Y miniplate with a detachable C-tube head (C-chin plate; Jin Biomed Co., Bucheon, Korea) used to fixate an anterior segmental osteotomy and provide skeletal anchorage during orthodontic tooth movement. Cases were selected for this study from patients who underwent anterior segmental osteotomy under local anesthesia. A detachable C-tube head portion was combined with a double-Y chin plate. The double-Y chin plates were fixated between the osteotomy segments and the mandibular base with screws in a conventional way. The C-tube head portion exited the tissue near the mucogingival junction. Biocreative Chin Plates were placed on the anterior segmental osteotomy sites. The device allowed 3 points of fixation: 1, minor postosteotomy vertical adjustment of the segment during healing; 2, minor shift of the midline during healing; and 3, to serve as temporary skeletal anchorage device during the post-anterior segmental osteotomy orthodontic treatment. When tooth movement goals are accomplished, the C-tube head of the chin plate can be easily detached from the fixation miniplate by twisting the head using a Weingart plier under local anesthesia. This dual-purpose device spares the patient from the need for 2 separate installations for stabilization of osteotomy segments. The dual-purpose double-Y miniplate combined with a C-tube head (Biocreative Chin Plate) provided versatile application of 3 points of post-osteotomy fixation and of temporary skeletal anchorage for orthodontic tooth movement.

There is a growing interest in developing brain PET scanners with high sensitivity and high spatial resolution for early diagnosis of neurodegenerative diseases and studies of brain functions. Sensitivity of the PET scanner can be improved by increasing the solid angle. However, conventional PET scanners are designed based on a cylindrical geometry, which may not be the most efficient design for brain imaging in terms of the balance between sensitivity and cost. We proposed a dedicated brain PET scanner based on a hemispheric shape detector and a chin detector (referred to as the helmet-chin PET), which is designed to maximize the solid angle by increasing the number of lines-of-response in the hemisphere. The parallax error, which PET scanners with a large solid angle tend to have, can be suppressed by the use of depth-of-interaction detectors. In this study, we carry out a realistic evaluation of the helmet-chin PET using Monte Carlo simulation based on the 4-layer GSO detector which consists of a 16  ×  16  ×  4 array of crystals with dimensions of 2.8  ×  2.8  ×  7.5 mm3. The purpose of this simulation is to show the gain in imaging performance of the helmet-chin PET compared with the cylindrical PET using the same number of detectors in each configuration. The sensitivity of the helmet-chin PET evaluated with a cylindrical phantom has a significant increase, especially at the top of the (field-of-view) FOV. The peak-NECR of the helmet-chin PET is 1.4 times higher compared to the cylindrical PET. The helmet-chin PET provides relatively low noise images throughout the FOV compared to the cylindrical PET which exhibits enhanced noise at the peripheral regions. The results show the helmet-chin PET can significantly improve the sensitivity and reduce the noise in the reconstructed images.

The chin-down posture is generally recommended in patients with neurogenic dysphagia to prevent tracheal aspiration; however, its effectiveness has not been demonstrated. To videofluoroscopically (VDF) assess the effectiveness of chin-down posture to prevent aspiration in patients with neurogenic dysphagia secondary to acquired brain injury. Randomized, alternating, cross-over study (with and without the chin-down posture) in 47 patients with a VDF diagnosis of aspiration [31 stroke, 16 traumatic brain injury (TBI)] and 25 controls without aspiration (14 stroke, 11 TBI). During the chin-down posture, 55% of patients avoided aspiration (40% preswallow aspiration and 60% aspiration during swallow). The percentage was similar in both etiologies (58% stroke and 50% TBI). Fifty-one percent of patients had silent aspiration; of these, 48% persisted with aspiration while in the chin-down posture. A statistically significant relationship was found between the existence of pharyngeal residue, cricopharyngeal dysfunction, pharyngeal delay time and bolus volume with the persistence of aspiration. The chin-down posture did not change swallow biomechanics in patients without aspiration. Only half the patients with acquired brain injury avoided aspiration during cervical flexion; 48% of silent aspirators continued to aspire during the maneuver. Several videofluoroscopic parameters were related to inefficiency of the maneuver. Therefore, the indication for chin-down posture should be evaluated by videofluoroscopic examination. © 2012 Blackwell Publishing Ltd.

Secondary Genioplasties for the Treatment of Chin Deformities After Orthognathic Surgery in Asian Women: Defining the Aesthetic Importance of Managing the Chin Shape in Orthognathic Surgery.

Achieving aesthetically favorable results in orthognathic surgery is equally as important as good postoperative occlusion and jaw function. Orthognathic surgery that only changes profile or proportion in the vertical dimension can often lead to patient's dissatisfaction and additional surgical revision. To achieve maximal aesthetic improvement and postoperative patient's satisfaction, the chin shape should be considered as important a component of orthognathic surgery as dental occlusion or jaw function. From April 2010 to January 2014, 82 female patients with aesthetic complaints after previous orthognathic surgery visited our clinic for reevaluation and management. Among those 82 patients, 54 patients who were dissatisfied with their lower facial shape from the frontal view underwent revision surgery with narrowing genioplasty and contouring of the lower border of the mandible. Facial shapes, when viewed from the front in all patients, became more slender and balanced postoperatively, and there was no need for additional surgical revisions in this series. There were no significant complications caused by our surgical revisions. Good aesthetic results were obtained after 54 secondary genioplasties for chin deformities after orthognathic surgery. These results suggest that surgeons should give more attention to managing chin shape when performing orthognathic surgery to meet the high aesthetic demands of patients and to avoid surgical revisions.

The chin bar of motorcycle full-face helmets is the most likely region of the helmet to sustain impacts during accidents, with a large percentage of these impacts leading to basilar skull fracture. Currently, helmet chin bars are designed to mitigate the peak acceleration at the centre of gravity of isolated headforms, as required by standards, but they are not designed to mitigate the neck force, which is probably the cause of basilar skull fracture, a type of head injury that can lead to fatalities. Here we test whether it is possible to increase the protection of helmet chin bars while meeting standard requirements. Fibre-reinforced composite shells are commonly used in helmets due to their lightweight and energy absorption characteristics. We optimize the ply orientation of a chin bar made of fibre-reinforced composite layers for reduction of the neck force in a dummy model using a computational approach. We use the finite element model of a human head/neck surrogate and measure the neck axial force, which has been shown to be correlated with the risk of basilar skull fracture. The results show that by varying the orientation of the chin bar plies, thus keeping the helmet mass constant, the neck axial force can be reduced by approximately 30% while ensuring that the helmet complies with the impact attenuation requirements prescribed in helmet standards.

To test whether the mandibular retromolar region renders different results from the chin region with respect to the amount of bone available for the harvesting of block grafts. Sixty cone beam computed tomography (CBCT) scans of mandibles of adult patients without pathologic findings in the chin and retromolar region were included. According to the number of mandibular teeth, 20 CBCT data sets were allocated to each of the following groups: group M1: dentition 36-46; group M2: dentition 37-47; and group M3: dentition 38-48. For the potential donor sites in the chin and the retromolar regions, the volume (VChin , VRetro ), the length (LChin , LRetro ), the height (HChin , HRetro ) and the width (HChin , HRetro ) were assessed using a computer software. Moreover, the chin was examined for the presence and the localization of the mandibular incisive canal. To compare the donor sites in the chin and in the retromolar regions, the quotients VRetro /VChin , LRetro /LChin , HRetro /HChin and WRetro /WChin were calculated and tested using the Wilcoxon signed-rank test or the sign test. The mean bone volume VChin measured 3.5 ± 1.3 cm(3) (SD), whereas the overall VRetro amounted to 1.8 ± 1.1 cm(3) (SD). VRetro amounted to 2.6 ± 1.4 cm(3) (SD) in the group M1, 1.8 ± 0.5 cm(3) in the group M2 and 1.0 ± 0.4 cm(3) in the group M3. For the group M1, VRetro /VChin measured 82 ± 39% (P = 0.036). VRetro /VChin reached 57 ± 20% in the group M2 and 32 ± 12% in the group M3 (P < 0.001). The mandibular incisive canal was detected in 97% of the CBCT scans. The distance between the mandibular incisive canal and the apices of the central incisors measured 10.5 ± 3.5 mm. The amount of bone available for the harvesting of cortico-cancellous blocks in the chin region was superior in comparison with the mandibular retromolar region. In the absence of the second and the third molars, the amount of bone harvestable in the retromolar region reached

Background: The treatment of Class III malocclusion has been challenging for orthodontists. Among a plethora of treatment modalities, the chin-cup is considered a traditional appliance for early orthopedic intervention. Objective: The present study aims to investigate the current scientific evidence regarding the effectiveness of chin-cup therapy in Class III malocclusion of prognathic growing patients. Method: A systematic review of the literature was conducted using PubMed/Medline and the Cochrane Central Register of Controlled Trials from January 1954 to October 2015. Articles were selected based on established inclusion/ exclusion criteria. Results: The search strategy resulted in 3285 articles.14 studies were selected for the final analysis. They were all CCTs, 13 of retrospective and 1 of prospective design. Methodological quality was evaluated by a risk of bias assessment, as suggested by the Cochrane Risk of Bias Assessment Tool for Non-Randomized Studies on Interventions. The reported evidence presented favorable short-term outcomes both in hard and soft tissues improving the Class III profile, as well as desirable dento-alveolar changes, positively affecting the Class III malocclusion. Conclusion: There is considerable agreement between studies that chin-cup therapy can be considered for the short-term treatment of growing patients with Class III malocclusion, as indicated by favorable changes both in the hard and soft tissues. The existence of considerable risk of bias in all selected studies and the unclear long-term effectiveness of chin-cup therapy highlight the need for further investigation to draw reliable conclusions.

This article discusses the application of computer-aided design and rapid prototyping techniques in prosthetic chin augmentation for mild microgenia. Nine cases of mild microgenia underwent an electrobeam computer tomography scan. Then we performed three-dimensional reconstruction and operative design using computer software. According to the design, we determined the shape and size of the prostheses and made an individualized prosthesis for each chin augmentation with the rapid prototyping technique. With the application of computer-aided design and a rapid prototyping technique, we could determine the shape, size, and embedding location accurately. Prefabricating the individual prosthesis model is useful in improving the accuracy of treatment. In the nine cases of mild microgenia, three received a silicone implant, four received an ePTFE implant, and two received a Medpor implant. All patients were satisfied with the results. During follow-up at 6-12 months, all patients remained satisfied. The application of computer-aided design and rapid prototyping techniques can offer surgeons the ability to design an individualized ideal prosthesis for each patient.

Erycibe henryi Prain ("Ting Kung Teng"), a species of Convolvulaceae, has been used in Chinese medicine to relieve pain involving the musculoskeletal system, such as arthritis, sciatica, and traumatic tissue swelling. E. henryi can be mistaken for another herbal plant, Tripterygium wilfordii Hook F, used to treat gouty arthritis. We report here three cases of E. henryi poisoning. All three cases presented with vomiting, diarrhea, salivation, diaphoresis, lacrimation, and rhinorrhea; two patients also had miosis, hypothermia, bradycardia, hypotension, and ventricular tachyarrhythmias. Laboratory abnormalities included leucocytosis, hyperglycemia, hyperamylasemia, hypocalcemia, and transiently elevated liver enzymes, creatinine and creatinine phosphokinase. The active constituents of E. henryi include several tropane alkaloids, which exhibit cholinergic activities. Gastrointestinal disturbances and ventricular tachyarrhythmias may occur with ingestion of either E. henryi or T. wilfordii, but the cholinergic symptoms can help to differentiate them.

Objective In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). Methods Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-dimensional temporomandibular fossa and mandible images were reconstructed, and angular, linear, and volumetric parameters were measured. Results For all 28 individuals, the chin was found to deviate to the cleft side by 1.59 mm. Moreover, among these 28 individuals, only 7 showed distinct (more than 4 mm) chin deviation, which was toward the cleft side. Compared to the non-cleft side, the mandibular body length, frontal ramal inclination, and vertical position of the condyle were lower and inclination of the temporomandibular fossa was steeper on the cleft side. Furthermore, the differences in inclination of the temporomandibular fossa, mandibular body length, ramus length, and condylar volume ratio (non-deviated/deviated) were positively correlated with chin deviation. Conclusions UCLP individuals show mild chin deviation to the cleft side. Statistical differences were noted in the parameters that represented positional and morphological asymmetries of the mandible and temporomandibular fossa; however, these differences were too small to indicate clinical significance.

It is believed that defects in upper airway neuromuscular control play a role in sleep apnea pathogenesis. Currently, there is no simple and non-invasive method for evaluating neuromuscular activity for the purpose of screening in patients with obstructive sleep apnea. This study was designed to assess the validity of chin surface electromyography of routine polysomnography in evaluating the neuromuscular activity of obstructive sleep apnea subjects and probe the neuromuscular contribution in the pathogenesis of the condition. The chin surface electromyography of routine polysomnography during normal breathing and obstructive apnea were quantified in 36 male patients with obstructive sleep apnea. The change of chin surface electromyography from normal breathing to obstructive apnea was expressed as the percent compensated electromyography value, where the percent compensated electromyography value = (normal breath surface electromyography - apnea surface electromyography)/normal breath surface electromyography, and the percent compensated electromyography values among subjects were compared. The relationship between sleep apnea related parameters and the percent compensated electromyography value was examined. The percent compensated electromyography value of the subjects varied from 1% to 90% and had a significant positive correlation with apnea hypopnea index (R(2) = 0.382, P < 0.001). Recording and analyzing chin surface electromyography by routine polysomnography is a valid way of screening the neuromuscular activity in patients with obstructive sleep apnea. The neuromuscular contribution is different among subjects with obstructive sleep apnea.

Numb chin syndrome, sometimes called numb lip syndrome, is an uncommon but well-recognized symptom in medical oncology. It may be a metastatic neurologic manifestation of malignancy, often with no clinically visible pathologic finding. The authors report a numb chin syndrome as a manifestation possible breast cancer metastasis around dental implants in a 69-year-old woman. The patient was presented with complaint of numbness in the lower jaw. Medical anamnesis revealed a metastatic breast carcinoma (CA). Radiographic imaging with conventional panoramic radiography and cone beam computed tomographic examination, revealed a moth-eaten shape, radiolucent, and radiopaque mixed appearance around the dental implants that was related with possible metastasis of the breast cancer. Numb chin syndrome is almost unknown within the dental and oral and maxillofacial community, despite being well reported in the medical literature. General dentists, oral medicine specialists, and oral and maxillofacial surgeons must be aware of this condition to consider metastatic cancer in patients with unexplained facial hypoesthesia. Moreover, although the development of metastatic lesions around implants is an uncommon pathologic finding, the examination of peri-implant lesion should be performed carefully considering the entire pathologic situations.

Do numerical rating scales and the Roland-Morris Disability Questionnaire capture changes that are meaningful to patients with persistent back pain?

2010-07-01

To investigate patients' views about two common outcome measures used for back pain: Numerical Rating Scales for pain and the Roland-Morris Disability Questionnaire. Thirty-six working adults who had previously sought primary care for back pain and who could speak and read English. Eight focus groups were conducted to explore participants' views about the 11-point Numerical Rating Scales and the 24-item Roland-Morris Disability Questionnaire. Each group was led by a facilitator and an interview topic guide was used. Audio recordings of focus groups were transcribed verbatim. Framework analysis was used to chart participants' views and an interpretive analysis performed to explain the findings. Participants reported that neither the Roland-Morris nor the Numerical Rating Scales captured the complex personal experience of pain or relevant changes in their condition. The time-frame of assessment was identified as particularly problematic and the Roland-Morris did not capture relevant functional domains. This study provides empirical data that working adults with persistent back pain consider these clinical outcome measures largely inadequate. These measures currently used for back pain may contribute to misleading conclusions about treatment efficacy and patient recovery.

The aim of the study was to assess the connectivity between magnetoencephalographic (MEG) dipoles in the temporal lobe and Rolandic region in children with temporal lobe epilepsy using diffusion tensor imaging (DTI) tractography. Six pediatric patients with intractable focal epilepsy had MEG performed, which showed MEG dipoles over both temporal and Rolandic regions in a unilateral hemisphere. DTI tractography was performed on each patient. Six control subjects were studied for comparison. Two volumes of interest (VOIs) that encompassed the MEG dipoles were drawn, one placed in temporal lobe and the other in Rolandic region. Similar VOIs were placed in the contralateral side in the patients and on both sides in controls. Fractional anisotropy (FA) and trace of the external capsules were compared between patients and controls. In all patients, a tractography pathway traversing through the external capsule, connecting the temporal and Rolandic MEG dipoles, was visualized. However, on the contralateral hemisphere in each patient, there was no evidence of a similar fiber tract. There was no corresponding tractography pathway identified in either hemisphere within the controls. There were no significant differences in FA and trace between the seizure focus side and contralateral side in the patients. There was no significant difference in FA, but a difference in trace between patients and controls. We have found aberrant tractography pathway traversing through the external capsule, connecting two distant foci of epileptiform activity. Chronic interictal epileptogenic discharge could play a causal role in the de novo organization of these tracts.

The aim of this survey study was to assess the influence of chin prominence on the perception of profile esthetics between genders by orthodontists, oral and maxillofacial surgeons (OMF), plastic surgeons, orthognathic patients and laypersons. A total of 731 observers participated in this study. Profile photographs of one female and one male showing ideal soft tissue values, skeletal class 1 relationship, and normodivergent facial type were modified with photo editing program (Adobe Photoshop CC software), so that the chin was moved posteriorly up to 10 mm and anteriorly up to 8 mm at 2-mm intervals. Participants were asked to rate 11 female and 11 male profile images and to assess whether surgery was needed. Within the limits of this study, ideal, slightly concave and slightly convex profiles for females, and ideal and slightly concave profiles for males were found more acceptable. Surgery was desired for 50.9% of retrusive profiles and 57.3% of protrusive profiles. Female participants had a higher rate of desire for surgery than male participants, and clinicians desired surgery significantly less than others. Desire for surgery started from 4 mm in males and females for all groups, from -6 mm in orthodontists and OMFs, from -4 mm in other groups in females, and from -6 mm in males for all groups. Clinicians tend to operate more pronounced cases when compared to laypeople. A significantly higher rate of surgery was desired for protrusive chin profiles, and female participants had a higher desire for surgery.

In the repair of extensive lower lip and chin defects, the reconstruction of vermilion at the same time is a great challenge to plastic surgeons. We describe a novel method for the reconstruction of lower vermilion with musculomucosal flap from the upper lip in the repair of extensive lower lip and chin defects. Two patients underwent extensive lower lip and chin reconstruction together with vermilion reconstruction. This technique used 3 basic components: musculomucosal flap from the upper lip, buccal mucosal advancement flap, and cutaneous rotational flap from the neck. All the flaps survived without significant complications. Labial function in the motions of expression and speaking was maintained. The patients could basically close their mouths completely, and there were no drooping or small-mouth deformities postoperatively. Functional and cosmetically acceptable lower-lip and chin reconstructions in both patients were achieved.

Paradoxical vocal fold motion (PVFM) is characterized by vocal fold adduction during respiration. Benign Rolandic epilepsy (BRE) is the most common childhood epilepsy and can cause oropharyngolaryngeal or facial manifestations. A 9-year-old male presented with intermittent apnea lasting 30-60 seconds and presumed PVFM. The patient's physical and fiberoptic exam were normal. He was admitted and found to have episodes of oxygen desaturation, neck twitching, and tongue burning. An EEG revealed focal epilepsy. After starting anti-epileptic medications, he had resolution of symptoms. Our patient was eventually diagnosed with BRE, a focal onset epilepsy that can mimic primary otolaryngologic disease.

Consuming thicker fluids and swallowing in the chin-tuck position has been shown to be advantageous for some patients with neurogenic dysphagia who aspirate due to various causes. The anatomical changes caused by these therapeutic techniques are well known, but it is unclear whether these changes alter the cerebral processing of swallow-related sensorimotor activity. We sought to investigate the effect of increased fluid viscosity and chin-down posture during swallowing on brain networks. 55 healthy adults performed water, nectar-thick, and honey thick liquid swallows in the neutral and chin-tuck positions while EEG signals were recorded. After pre-processing of the EEG timeseries, the time-frequency based synchrony measure was used for forming the brain networks to investigate whether there were differences among the brain networks between the swallowing of different fluid viscosities and swallowing in different head positions. We also investigated whether swallowing under various conditions exhibit small-world properties. Results showed that fluid viscosity affects the brain network in the Delta, Theta, Alpha, Beta, and Gamma frequency bands and that swallowing in the chin-tuck head position affects brain networks in the Alpha, Beta, and Gamma frequency bands. In addition, we showed that swallowing in all tested conditions exhibited small-world properties. Therefore, fluid viscosity and head positions should be considered in future swallowing EEG investigations. PMID:27693396

1997-03-01

The overall aim was to evaluate whether a trackball could be used for communication by people who cannot speak due to severe motor impairment. The precision of trackball control by isolated jaw movements or a combination of jaw and head movements was evaluated in 18 healthy physical-education students, free of overt symptoms of craniomandibular dysfunction. The participants were asked to operate a trackball using the chin to type a standard text of four short sentences. There were two experimental situations: nine participants performed the typewriting task with their heads fixed; the other nine performed this task with free head movements. Trackball operation moved to the cursor over an alphabetical keyboard displayed on a computer screen and character selection was made by depression of the left-hand click button using the chin. Participants were asked to perform the task as quickly and accurately as possible. Result showed that those with free head movement typed the test significantly faster than those restricted to using only their jaw muscles. The mean time per character selection was 2.4 s (SD 0.3) for the group with free head movement and 2.7 s (SD 0.3) for the group using only jaw muscles. Group scores were not significantly different with regard to accuracy. It is suggested that a chin-operated trackball could be used for communication applications both with and without neck movements.

GM2 gangliosidosis associated with a HEXA missense mutation in Japanese Chin dogs: a potential model for Tay Sachs disease.

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. Copyright © 2012 Elsevier Inc. All rights reserved.

To evaluate the clinical outcomes of bilateral superior oblique posterior 7/8th tenectomy with inferior rectus recession on improving chin-up head positioning in patients with horizontal nystagmus. Medical records were reviewed from 2007 to 2017 for patients with nystagmus and chin-up positioning of 15° or more who underwent combined bilateral superior oblique posterior 7/8th tenectomy with an inferior rectus recession of at least 5 mm. Thirteen patients (9 males and 4 females) were included, with an average age of 7.3 years (range: 1.8 to 15 years). Chin-up positioning ranged from 15° to 45° degrees (average: 30°). Three patients had prior horizontal muscle surgeries, 1 for esotropia and 2 for horizontal null zones causing anomalous face turns. Ten patients underwent other concomitant eye muscle surgery: 3 had esotropia, 1 had exotropia, and 2 had biplanar nystagmus null point requiring a horizontal Anderson procedure. Four patients underwent simultaneous bilateral medial rectus tenotomy and reattachment. All patients had improved chin-up positioning. Eight patients had complete resolution, whereas 5 had minimal residual chin-up positioning. Three patients developed an eccentric horizontal gaze null point with compensatory anomalous face turn with onset 2 weeks, 2 years, and 3 years postoperatively. Average follow-up was 42.7 months. No postoperative pattern deviations, cyclodeviations, or inferior oblique overaction were seen. No surgical complications were noted. Bilateral superior oblique posterior 7/8th tenectomy in conjunction with bilateral inferior rectus recession is a safe and effective procedure for improving chin-up head positioning in patients with horizontal nystagmus with a down gaze null point.

Rolandic epilepsy (RE) is an idiopathic focal childhood epilepsy with a well-established neuropsychological profile of language impairment. The aim of this study is to provide a functional correlate that links rolandic (sensorimotor) pathology to language problems using functional MRI. Twenty-three children with RE (8-14 years old) and 21 matched controls underwent extensive language assessment (Clinical Evaluation of Language Fundamentals). fMRI was performed at rest and using word generation, reading, and finger tapping paradigms. Since no activation group differences were found, regions of interest (ROIs) were defined at pooled (patients and controls combined) activation maxima and in contralateral homotopic cortex, and used to assess language lateralization as well as for a resting-state connectivity analysis. Furthermore, the association between connection strength and language performance was investigated. Reduced language performance was found in the children with RE. Bilateral activation was found for both language tasks with some predominance of the left hemisphere in both groups. Compared to controls, patient connectivity was decreased between the left sensorimotor area and right inferior frontal gyrus (p<0.01). For this connection, lower connectivity was associated with lower language scores in the patient group (r=0.49, p=0.02), but not in the controls. Language laterality analysis revealed bilateral language representation in the age range under study (8-14 years). As a consequence, the connection of reduced functional connectivity we found represents an impaired interplay between motor and language networks, and aberrant functional connectivity associated with poorer language performance. These findings provide a first neuronal correlate in terms of aberrant resting-state functional connectivity for language impairment in RE. Copyright © 2013 Elsevier B.V. All rights reserved.

Patients with bimaxillary protrusion may have an unattractive profile with a retruded chin contour. Correction of the severely protrusive anterior alveolar bone and teeth combined with a moderate open bite without orthognathic surgery can be challenging. This case report describes the orthodontic treatment of a woman with severe bimaxillary protrusion and a moderate open bite. Excellent chin morphology and facial appearance were obtained with the extraction of 4 first premolars and 4 third molars, and total distalization of both arches with 4 mini-implants, one in each quadrant between the second premolar and the first molar. The total treatment time was 30 months. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

Our purpose was to evaluate whether the application of serial three-dimensional (3D) sonography and the mandibular size monogram can allow observation of dynamic changes in facial features, as well as chin development in utero. The mandibular size monogram has been established through a cross-sectional study involving 183 fetal images. The serial changes of facial features and chin development are assessed in a cohort study involving 40 patients. The monogram reveals that the Biparietal distance (BPD)/Mandibular body length (MBL) ratio is gradually decreased with the advance of gestational age. The cohort study conducted with serial 3D sonography shows the same tendency. Both the images and the results of paired-samples t test (P<.001) statistical analysis suggest that the fetuses develop wider chins and broader facial features in later weeks. The serial 3D sonography and mandibular size monogram display disproportionate growth of the fetal head and chin that leads to changes in facial features in late gestation. This fact must be considered when we evaluate fetuses at risk for development of micrognathia.

Recently, a number of portable devices designed for full polysomnography at home have appeared. However, current scalp electrodes used for electroencephalograms are not practical for patient self-application. The aim of this study was to evaluate the suitability of recently introduced forehead electroencephalogram electrode set and supplementary chin electromyogram electrodes for sleep staging. From 31 subjects (10 male, 21 female; age 31.3 ± 11.8 years), sleep was recorded simultaneously with a forehead electroencephalogram electrode set and with a standard polysomnography setup consisting of six recommended electroencephalogram channels, two electrooculogram channels and chin electromyogram. Thereafter, two experienced specialists scored each recording twice, based on either standard polysomnography or forehead recordings. Sleep variables recorded with the forehead electroencephalogram electrode set and separate chin electromyogram electrodes were highly consistent with those obtained with the standard polysomnography. There were no statistically significant differences in total sleep time, sleep efficiency or sleep latencies. However, compared with the standard polysomnography, there was a significant increase in the amount of stage N1 and N2, and a significant reduction in stage N3 and rapid eye movement sleep. Overall, epoch-by-epoch agreement between the methods was 79.5%. Inter-scorer agreement for the forehead electroencephalogram was only slightly lower than that for standard polysomnography (76.1% versus 83.2%). Forehead electroencephalogram electrode set as supplemented with chin electromyogram electrodes may serve as a reliable and simple solution for recording total sleep time, and may be adequate for measuring sleep architecture. Because this electrode concept is well suited for patient's self-application, it may offer a significant advancement in home polysomnography. © 2016 European Sleep Research Society.

Although benign, rolandic epilepsy (RE) or benign childhood epilepsy with centro-temporal spikes is often associated with language impairment. Recently, fronto-rolandic EEG abnormalities have been described in children with developmental dysphasia (DD), suggesting an interaction between language impairment and interictal epileptiform discharges. To investigate if a behavioral-linguistic continuum between RE and DD exists, a clinical prospective study was carried out to evaluate the language profile of 15 children with RE and 22 children with DD. Language skills were assessed using an extensive, standardized test battery. Language was found to be impaired in both study groups, however RE and DD were associated with distinct language impairment profiles. Children with RE had difficulties with sentence comprehension, semantic verbal fluency and auditory short-term memory, which are unrelated to age of epilepsy onset and laterality of epileptic focus. In children with DD, sentence comprehension and verbal fluency were among their relative strengths, whereas sentence and lexical production constituted relative weaknesses.

Mental nerve neuropathy is usually due to local trauma or dental causes, but may be a manifestation of malignancy. A patient with virologically controlled human immunodeficiency virus (HIV) infection presented with a 'numb chin' on the background of long-standing night sweats, malaise and weight loss, worsening respiratory symptoms, and lymphadenopathy. Burkitt non-Hodgkin lymphoma was diagnosed from histology of a lymph node. Imaging (magnetic resonance imaging and 18 fluorodeoxyglucose [FDG]-positron emission tomography-computed tomography [PET-CT]) showed abnormal intracranial enhancement of the right mandibular nerve and extensive 18 FDG-avid lymphadenopathy above and below the diaphragm, focal lesions in the spleen and within the right mandible. The patient received chemotherapy and remains in clinical and radiological remission seven years later. This case highlights the need for clinicians to maintain a high index of suspicion for underlying malignancy when an HIV-infected patient presents with new onset of a 'numb chin'. Additionally, it demonstrates the importance of functional 18 FDG-PET-CT and neuroimaging in order to identify site(s) of pathology.

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. 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. 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.

The most common instruments developed to assess the functional status of patients with Non specific low back pain is the Roland-Morris Disability Questionnaire (RMDQ). Clinical and epidemiological research related to low back pain in the Gujarati population would be facilitated by the availability of well-established outcome measures. To find the reliability, validity, sensitivity and specificity of the Gujarati version of the RMDQ for use in Non Specific Chronic low back pain. A reliability, validity, sensitivity and specificity study of Gujarati version of the Roland-Morris Disability Questionnaire (RMDQ). Thirty out patients with Non Specific Chronic low back pain were assessed by the RMDQ. Reliability is assessed by using internal consistency and the intra-class correlation coefficient (ICC). Internal construct validity is assessed by RASCH Analysis and external construct validity is assessed by association with pain and spinal movement. Clinical calculator was used to determine the sensitivity and specificity. Internal consistency of the RMDQ is found to be adequate (> 0.65) at both times, with high ICC's also at both time points. Internal construct validity of the scale is good, indicating a single underlying construct. Expected associations with pain and spinal movement confirm external construct validity. The Sensitivity and Specificity at cut off point of 0.5 was 80% and 84% with respectively positive predictive value (PPV) of 83.33% and negative predictive value (NPV) of 80.76%. The Questionnaire is at the ordinal level. The RMDQ is a one-dimensional, ordinal measure, which works well in the Gujarati population.

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 aims of this work were to compare the performances of male and female cadet and junior judo athletes and to develop classificatory tables to these judo-specific tests for international-level from these ages. Data collected during training camps of male and female cadet and junior judo teams from three nations (Brazil, Serbia, and Spain) were analyzed, totalizing 252 individual results of special judo fitness test (SJFT), and 222 and 208 of dynamic and isometric judogi chin-up tests, respectively. Juniors performed better than cadets in the SJFT, with higher number of throws in A, B, C, and total (P<0.001 for all comparisons), lower final heart rate (P=0.021), and lower index (P<0.001), as well as higher relative performance in the dynamic chin-up test (P<0.001). Furthermore, male athletes presented better performance compared to female athletes in the SJFT (higher number of throws in A, B and total, and lower index) and in the isometric and dynamic chin-up tests (higher absolute and relative performances) (P<0.001 for all comparisons). Considering these differences, tables were established by sex and age groups, using percentile values. Thereby, each of the parameters of the SJFT (number of throws, heart rate after and 1 min after the test, and SJFT index), as well as absolute and relative results in chin-up judogi tests, were classified by sex and age. These classificatory tables can be useful for judo coaches to monitor specific physical performance during different phases of periodization process. PMID:29740559

2012-01-01

The purpose of this investigation was to undertake an objective and quantitative evaluation of how severity of asymmetries affecting the mandible and chin point influence perceived attractiveness. The mandible and chin point of idealized male and female frontal facial images were altered in 5-mm increments from 0 to 25 mm and to the left and right, to represent horizontal, vertical, and combined asymmetry affecting these regions. These images were rated on a 7-point Likert scale by a preselected group of orthognathic patients before treatment, clinicians, and laypeople. In relation to a 5-mm asymmetry, observers progressively decreased attractiveness ratings and increased the desire for surgery for greater asymmetries. Clinicians and patients were found to be more critical than laypeople. The desire for surgery decreased by 3% for each year increase in age, was 53% less for men, and 45% greater for white observers. Asymmetry of 10 mm is perceived as being significant; at 5 mm and below, it is largely unnoticed. The greater the degree of asymmetry greater than 10 mm, the more noticeable and the greater the desire was for correction. Clinician and patient ratings were similar and more critical than ratings of laypeople. A desire for surgery was negligible for 5 mm of asymmetry but increased considerably at 10 mm and continued to increase with greater degrees of asymmetry. The highest-rated images showed perfect bilateral symmetry, whereas the lowest-rated images showed significant degrees of mandibular and chin asymmetry.

Aims. To verify the effectiveness of the maneuver application in swallowing therapy with PD. Materials and Method. We performed an open-label trial, with three groups compounds by PD individuals: the experimental group, control group, and orientation group. The study included PD patients with dysphagia. A cognitive screening, through a questionnaire about depression and quality of life, was conducted. Swallowing assessment was performed through (1) fiberoptic endoscopic evaluation of swallowing (FEES); (2) clinical evaluation and Functional Oral Intake Scale (FOIS); and (3) assessment of the quality life related to swallowing (SWALQOL). A therapeutic program, which consisted of chin-down postural maneuver and orientations on feeding, was applied. Both groups (EG and OG) received on-month therapeutic program. Results. A significant improvement in swallowing, evaluated by clinical assessment, was observed in solid (p < 0.001) and liquid (p = 0.022) consistencies in EG when compared to OG and CG. Patients in EG presented improvement in QoL, with the significant difference in comparison with the other groups, about domain frequency of symptoms (p = 0.029) in SWALQOL questionnaire. Conclusion. The postural maneuver chin-down improved swallowing performance and self-perception, but not the laryngeal signs. This trial is registered with registration number NCT02973698. PMID:28203475

Reconstructive surgery with chin block graft and esthetic rehabilitation of missing anterior tooth.

The complete and predictable restoration of the periodontium following infection or trauma remains a critical objective in regenerative therapy. Bone grafts remain among the most widely used therapeutic strategies for the correction of periodontal osseous defects. For periodontally compromised anterior teeth, reconstruction of the ridge along with natural tooth pontic serves both the purpose of regeneration and esthetics. The right lower central incisor of a 28-year-old male that was periodontally compromised was extracted. Autogenous chin grafting followed by retrograde surgery of the extracted tooth and replacement by natural tooth pontic was done. After 6 months, there was significant improvement in clinical picture and bone fill. This procedure provided excellent regenerative and esthetic results for the periodontally compromised lost anterior tooth.

Hair follicle nevi are rare, benign, congenital hamartomas that usually occur in the distribution of the first brachial arch. Histopathologically, the distinction between hair follicle nevus, trichofolliculoma, and accessory tragus has recently come into question, and it may be that they are all on a spectrum of the same condition. We report the case of a 7-day-old boy who presented with a "tag"-like lesion on his midline chin that had been present since birth. Biopsy of the lesion proved it to be a hair follicle nevus. © 2016 Wiley Periodicals, Inc.

Cross-culturally adapt and validate the Igbo Roland Morris Disability Questionnaire. Cross-cultural adaptation, test-retest, and cross-sectional psychometric testing. Roland Morris Disability Questionnaire was forward and back translated by clinical/non-clinical translators. An expert committee appraised the translations. Twelve participants with chronic low back pain pre-tested the measure in a rural Nigerian community. Internal consistency using Cronbach's alpha; test-retest reliability using intra-class correlation coefficient and Bland-Altman plot; and minimal detectable change were investigated in a convenient sample of 50 people with chronic low back pain in rural and urban Nigeria. Pearson's correlation analyses using the eleven-point box scale and back performance scale, and exploratory factor analysis were used to examine construct validity in a random sample of 200 adults with chronic low back pain in rural Nigeria. Ceiling and floor effects were investigated in the two samples. Modifications gave the option of interviewer-administration and reflected Nigerian social context. The measure had excellent internal consistency (α = 0.91) and intraclass correlation coefficient (ICC =0.84), moderately high correlations (r > 0.6) with performance-based disability and pain intensity, and a predominant uni-dimensional structure, with no ceiling or floor effects. Igbo Roland Morris Disability Questionnaire is a valid and reliable measure of pain-related disability. Implications for rehabilitation Low back pain is the leading cause of years lived with disability worldwide, and is particularly prevalent in rural Nigeria, but there are no self-report measures to assess its impact due to low literacy rates. This study describes the cross-cultural adaptation and validation of a core self-report back pain specific disability measure in a low-literate Nigerian population.

2016-04-01

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.

As the United States moves down the road of pay-for-performance (P4P), concerns about unintended consequences are foremost in the minds of policymakers. Initial results from the world's most ambitious P4P program, the United Kingdom's Quality and Outcomes Framework (QOF), indicate that while quality improvements exceeded expectations, so too did the amount of funds paid out, straining the National Health Service (NHS) budget. Martin Roland, one of the leading U.K. health services researchers and an adviser to the QOF, gives his views on what went right and what went wrong, and he offers his advice to the United States about using financial incentives to improve quality.

[Neuropsychological alterations are frequent in rolandic epilepsy and its atypical developments].

PubMed

Pesantez-Rios, G; Martinez-Bermejo, A; Pesantez-Cuesta, G

2016-08-01

Rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes is called benign because its seizures are usually favourable and due to the spontaneous normalisation of the electroencephalogram on reaching puberty. Nevertheless, evidence has been found of the impact on cognitive development with the presence of heterogeneous cognitive deficits, especially related to persistent intercritical discharges during non-REM sleep. The aim of this study is to examine the epileptogenic networks involved in the neuropsychological disorders of this pathology. A common feature of the atypical developments is persistent epileptic activity during slow sleep, which plays an important role in the development of the neurocognitive deficits that are associated to this pathology. Factors such as the age at onset of the epilepsy, the onset of the atypical development, the location of the interictal discharges and the continuous epileptic activity during sleep that persists for more than two years can trigger changes in the functioning of the neurocognitive networks. This may result in deficits in the neuropsychological functions, which may even be irreversible. A close clinical and electroencephalographic follow-up is necessary. Moreover, formal neuropsychological studies must be conducted as of the onset of benign childhood epilepsy with centrotemporal spikes. This is even more necessary in cases in which there is an obvious atypical development in order to detect and prevent the neuropsychological deficits before they establish themselves on a definitive basis.

Secondary grafting of alveolar defects with iliac crest bone is a common treatment method in cleft patients. The aim of this study was to evaluate the effectiveness of the combination of symphysis bone, allograft, and platelet-rich fibrin in regeneration of alveolar defects compared with iliac bone graft. In this randomized clinical trial, patients with unilateral alveolar defects were divided randomly into two categories. Group A comprised patients in whom the combination of chin symphysis bone plus allogeneic bone material plus leukocyte- and platelet-rich fibrin was considered for treatment. Group B comprised patients in whom iliac bone graft was considered. Cone beam computed tomography before treatment and 1 year postoperatively was used for measurement of bone formation (bone volume in cubic centimeters). The data were analyzed by paired t and χ 2 tests via SPSS software (version 23; IBM, Armonk, NY). P < .05 was considered significant. Each group included 10 patients (with 6 male patients in group A and 5 male patients in group B). The mean age of patients in groups A and B was 9.5 ± 1.5 years and 9.9 ± 1.9 years, respectively. The mean volume of alveolar defects was 0.89 ± 0.29 cm 3 in group A and 0.95 ± 0.27 cm 3 in group B. The percentage of bone regeneration in groups A and B was 69.5% and 73.8%, respectively. It seems that chin symphysis bone plus allogeneic bone material plus platelet-rich fibrin is a proper combination for bone regeneration in alveolar defects with a small to moderate volume range.

Myiasis is the infestation of human beings with fly larvae which feed on host’s living or dead tissue. Diagnosis of this condition is made by the presence of larvae in affected body parts. The standard treatment is the mechanical removal of the maggots from the lesion and management of the general systemic condition. This paper report a case of myiasis at the chin region in a 45-year-old male managed by manual removal of larvae after topical application of turpentine oil, surgical debridement of necrotic tissues and antimicrobial therapy.

Seasonality of P wave microseisms from NCF-based beamforming using ChinArray

Wang, Weitao; Gerstoft, Peter; Wang, Baoshan

2018-06-01

Teleseismic P wave microseisms produce interference signals with high apparent velocity in noise cross-correlation functions (NCFs). Sources of P wave microseisms can be located with NCFs from seismic arrays. Using the vertical-vertical component NCFs from a large-aperture array in southwestern China (ChinArray), we studied the P wave source locations and their seasonality of microseisms at two period bands (8-12 and 4-8 s) with an NCF-based beamforming method. The sources of P, PP and PKPbc waves are located. The ambiguity between P and PP source locations is analysed using averaged significant ocean wave height and sea surface pressure as constraints. The results indicate that the persistent P wave sources are mainly located in the deep oceans such as the North Atlantic, North Pacific and Southern Ocean, in agreement with previous studies. The Gulf of Alaska is found to generate P waves favouring the 8-12 s period band. The seasonality of P wave sources is consistent with the hemispheric storm pattern, which is stronger in local winter. Using the identified sources, arrival times of the interference signals are predicted and agree well with observations. The interference signals exhibit seasonal variation, indicating that body wave microseisms in southwestern China are from multiple seasonal sources.

A page from "the drawer": how Roland Shack opened the door to the aberration theory of freeform optics

2014-09-01

Roland Shack is credited with a number of what appear to be spontaneous inventions in the 1970s, including the Shack- Hartmann wavefront sensor, the Shack Cube interferometer, and the subject of this talk, an entirely new and revealing approach to the aberration fields of imaging optical systems that has come to be called Nodal Aberration Theory and recently emerged as the aberration of rotationally nonsymmetric imaging optical systems with freeform surfaces. Prof. Shack's original impetus for considering a new approach to aberration theory was a puzzling through-focus star field photograph brought to him by astronomers in 1976 taken with the first large telescope made at the Optical Sciences Center, the 90" Bok Telescope. By 1977, he had developed the key mathematical moves needed to send aberration theory into an entirely new direction. He transferred this insight on one piece of engineering pad paper and moved on to other projects.

Numb chin syndrome is another rare syndrome associated with aggressive malignancies. Survival of these syndromes is dictated by the underlying disease and is usually dismal. Our 35-year-old patient experienced an early relapse of Burkitt lymphoma accompanied by syndromes, achieved second complete remission and underwent allogeneic stem cell transplantation. He remains alive and well >2 years after the transplant. To our knowledge, this is the longest reported survival of the two syndromes in the setting of BL relapse.

Tantrums, Emotion Reactions and Their EEG Correlates in Childhood Benign Rolandic Epilepsy vs. Complex Partial Seizures: Exploratory Observations.

PubMed

Potegal, Michael; Drewel, Elena H; MacDonald, John T

2018-01-01

We explored associations between EEG pathophysiology and emotional/behavioral (E/B) problems of children with two types of epilepsy using standard parent questionnaires and two new indicators: tantrums recorded by parents at home and brief, emotion-eliciting situations in the laboratory. Children with Benign Rolandic epilepsy (BRE, N = 6) reportedly had shorter, more angry tantrums from which they recovered quickly. Children with Complex Partial Seizures (CPS, N = 13) had longer, sadder tantrums often followed by bad moods. More generally, BRE correlated with anger and aggression; CPS with sadness and withdrawal. Scores of a composite group of siblings ( N = 11) were generally intermediate between the BRE and CPS groups. Across all children, high voltage theta and/or interictal epileptiform discharges (IEDs) correlated with negative emotional reactions. Such EEG abnormalities in left hemisphere correlated with greater social fear, right hemisphere EEG abnormalities with greater anger. Right hemisphere localization in CPS was also associated with parent-reported problems at home. If epilepsy alters neural circuitry thereby increasing negative emotions, additional assessment of anti-epileptic drug treatment of epilepsy-related E/B problems would be warranted.

Seabirds are amongst the most affected organisms by plastic pollution worldwide. Ingestion of marine debris has been reported in at least 122 species, and owing to the increasing global production and persistence of these anthropogenic materials within the marine environment, it is expected to be a growing problem to the marine fauna. Here we report evidence of an increasing frequency in marine debris ingestion and a decrease in the amount of plastic pellets ingested by White-chinned Petrels attending south Brazilian waters during the last three decades. Future studies comprising large temporal scales and large sample sizes are needed to better understand the trends of marine debris ingestion by seabirds. We expect our findings to highlight the need for prevention policies and mitigation measures to reduce the amount of solid litter in the oceans. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cross-sectional design. To explore (1) the factor structure of the Roland-Morris Disability Questionnaire (RMDQ), (2) whether there is a dominant factor, and (3) whether the potential factors are unique predictors of other aspects related to back pain. The RMDQ is one of the most recommended back-specific questionnaires assessing disability. The RMDQ is scored as a unidimensional scale summarizing answers to all 24 questions (Yes/No) regarding daily life functioning. However, there are indications that the scale is multidimensional. Patients (n = 457; age, 18-60 yr) with 8 to 12 weeks of back pain filled in questionnaires assessing subjective health complaints, emotional distress, instrumental and emotion-focused coping, and fear voidance behavior at baseline. A total of 371 patients (81.7%) filled in the RMDQ. Exploratory factor analysis was used to examine the factor structure of RMDQ items. Multiple regression analyses were used to assess whether the derived factors predicted relevant problems in back pain differently. Exploratory factor analysis showed indices of model fit for a 3-factor solution after removing 2 items because of low prevalence (19 and 24). Two items were removed because of cross-loadings and low loadings (2 and 22). No support for a dominant factor was found as the 3 factors were only moderately correlated (r = 0.34-0.40), and the ratio between the first and second eigenvalue was 2.6, not supporting essential unidimensionality. "Symptoms" were the factor that most strongly predicted subjective health complaints, whereas "avoidance of activity and participation" predicted fear avoidance behavior, instrumental and emotional coping. "Limitation in daily activities" did not predict any of these variables. The main findings of our study are that the RMDQ consists of 3 independent factors, and not 1 dominant factor as suggested previously. We think the time is now ripe to start treating and scoring the RMDQ as a multidimensional scale. N/A.

Proctophyllodes huitzilopochtlii Atyeo & Braasch 1966 (Acariformes: Astigmata: Proctophyllodidae), a feather mite, was found on feathers collected from five hummingbird species in California. This mite has not been previously documented on feathers from Anna's (Calypte anna [Lesson 1829]) or Black-chinned (Archilochus alexandri [Bourcier & Mulsant 1846]) Hummingbirds. A total of 753 hummingbirds were evaluated for the presence of mites by species (Allen's n = 112; Anna's n = 500; Black-chinned n = 122; Rufous n = 18; Calliope n = 1), sex (males n = 421; females n = 329; 3 unidentified), and age (juvenile n = 199; after-hatch-year n = 549; 5 unidentified). Of these 753 hummingbirds evaluated, mites were present on the rectrices of 40.9% of the birds. Significantly more Anna's Hummingbirds were positive for rectricial mites (59.2%) compared with 8.2% of Black-chinned, 0.9% of Allen's, 5.6% of Rufous Hummingbirds, and 0% for Calliope (p-value < 0.0001). Across all hummingbird species, male hummingbirds (44.9%) had a higher prevalence of rectricial mites compared to female hummingbirds (36.2%; p-value = 0.004), while juvenile hummingbirds (46.2%) had a non-significantly higher prevalence compared to after-hatch-year hummingbirds (39.0%; p-value = 0.089). On average, the percentage of the long axis of the rachis occupied by mites for the outer rectrices (R4 and R5) was 19%, compared to 11% for inner rectrices (R1 and R2), a significant difference (p-value = <0.0001). There was a marginal lack of significance for symmetrical distribution of tail mites with the mean left side percentage of long axis of the rachis occupied by mites being 16% and very close to the mean right side score of 18% (p-value = 0.003). The identification of the feather mite species was based on light microscopic morphometry, and mite distribution on feathers was further evaluated using tabletop scanning electron microscopy (TSEM). The hummingbird-feather mite relationship is not well understood

To investigate the effects of frontal facial type (FFT) and sex on preferred chin projection (CP) in three-dimensional (3D) facial images. Six 3D facial images were acquired using a 3D facial scanner (euryprosopic [Eury-FFT], mesoprosopic [Meso-FFT], and leptoprosopic [Lepto-FFT] for each sex). After normal CP in each 3D facial image was set to 10° of the facial profile angle (glabella-subnasale-pogonion), CPs were morphed by gradations of 2° from normal (moderately protrusive [6°], slightly protrusive [8°], slightly retrusive [12°], and moderately retrusive [14°]). Seventy-five dental students (48 men and 27 women) were asked to rate the CPs (6°, 8°, 10°, 12°, and 14°) from the most to least preferred in each 3D image. Statistical analyses included the Kolmogorov-Smirnov test, Kruskal-Wallis test, and Bonferroni correction. No significant difference was observed in the distribution of preferred CP in the same FFT between male and female evaluators. In Meso-FFT, the normal CP was the most preferred without any sex difference. However, in Eury-FFT, the slightly protrusive CP was favored in male 3D images, but the normal CP was preferred in female 3D images. In Lepto-FFT, the normal CP was favored in male 3D images, whereas the slightly retrusive CP was favored in female 3D images. The mean preferred CP angle differed significantly according to FFT (Eury-FFT: male, 8.7°, female, 9.9°; Meso-FFT: male, 9.8°, female, 10.7°; Lepto-FFT: male, 10.8°, female, 11.4°; p < 0.001). Our findings might serve as guidelines for setting the preferred CP according to FFT and sex.

Improving the colour match of free tissue transfers to the face with non-cultured autologous cellular spray--a case report on a chin reconstruction.

Animal bites can result in extensive avulsion injuries of the face justifying microsurgical replantation attempts. Reconstruction using local tissue harvesting increases the local morbidity while distant tissues can result in colour and skin texture mismatching. Skin grafting of the skin paddle by a split-thickness skin graft is a conventional approach to help overcome this problem. An 18-year-old patient was treated for a chin avulsion after a dog bite injury. The avulsed segment included the whole chin aesthetic unit and one-fifth of the lower lip. The segment was replanted on the inferior labial artery. The replantation failed and a reconstruction with a parascapular free flap was performed. Despite a debulking at 1 month, the aesthetic result had a poor colour match. The technique used to improve this was to de-epithelialise the skin and apply non-cultured autologous epidermal cells (NCAECs) 100 days after the reconstruction. The reconstruction was uneventful. At 3 months follow-up, the patient was able to purse her lips and had regained sensation. After 5 months, the free flap paddle was consistent in colour, pigmentation and texture with the surrounding skin. At 10 months, the patient's only complaint was residual firmness in her scar and flap. The long-term follow-up, over 23 months, confirmed the stability of the results. The use of an NCAEC spray to treat the dyschromia on a parascapular flap used for facial reconstruction is less invasive than split-thickness overgrafting and could extend the use of distant flaps that have been avoided due to poor colour match.

Proctophyllodes huitzilopochtlii Atyeo & Braasch 1966 (Acariformes: Astigmata: Proctophyllodidae), a feather mite, was found on feathers collected from five hummingbird species in California. This mite has not been previously documented on feathers from Anna’s (Calypte anna [Lesson 1829]) or Black-chinned (Archilochus alexandri [Bourcier & Mulsant 1846]) Hummingbirds. A total of 753 hummingbirds were evaluated for the presence of mites by species (Allen’s n = 112; Anna’s n = 500; Black-chinned n = 122; Rufous n = 18; Calliope n = 1), sex (males n = 421; females n = 329; 3 unidentified), and age (juvenile n = 199; after-hatch-year n = 549; 5 unidentified). Of these 753 hummingbirds evaluated, mites were present on the rectrices of 40.9% of the birds. Significantly more Anna’s Hummingbirds were positive for rectricial mites (59.2%) compared with 8.2% of Black-chinned, 0.9% of Allen’s, 5.6% of Rufous Hummingbirds, and 0% for Calliope (p-value < 0.0001). Across all hummingbird species, male hummingbirds (44.9%) had a higher prevalence of rectricial mites compared to female hummingbirds (36.2%; p-value = 0.004), while juvenile hummingbirds (46.2%) had a non-significantly higher prevalence compared to after-hatch-year hummingbirds (39.0%; p-value = 0.089). On average, the percentage of the long axis of the rachis occupied by mites for the outer rectrices (R4 and R5) was 19%, compared to 11% for inner rectrices (R1 and R2), a significant difference (p-value = <0.0001). There was a marginal lack of significance for symmetrical distribution of tail mites with the mean left side percentage of long axis of the rachis occupied by mites being 16% and very close to the mean right side score of 18% (p-value = 0.003). The identification of the feather mite species was based on light microscopic morphometry, and mite distribution on feathers was further evaluated using tabletop scanning electron microscopy (TSEM). The hummingbird–feather mite relationship is not well

Tea (Camellia sinensis) is an important economic crop in Taiwan. Particularly, two major commercial types of tea (Paochong tea and Oolong tea) which are produced in Taiwan are famous around the world, and they must be manufactured with specific cultivars. Nevertheless, many elite cultivars have been illegally introduced to foreign countries. Because of the lower cost, large amount of "Taiwan-type tea" are produced and imported to Taiwan, causing a dramatic damage in the tea industry. It is very urgent to develop the stable, fast and reliable DNA markers for fingerprinting tea cultivars in Taiwan and protecting intellectual property rights for breeders. Furthermore, genetic diversity and phylogenetic relationship evaluations of tea germplasm in Taiwan are imperative for parental selection in the cross-breeding program and avoidance of genetic vulnerability. Two STS and 37 CAPS markers derived from cytoplasmic genome and ESTs of tea have been developed in this study providing a useful tool for distinguishing all investigated germplasm. For identifying 12 prevailing tea cultivars in Taiwan, five core markers, including each one of mitochondria and chloroplast, and three nuclear markers, were developed. Based on principal coordinate analysis and cluster analysis, 55 tea germplasm in Taiwan were divided into three groups: sinensis type (C. sinensis var. sinensis), assamica type (C. sinensis var. assamica) and Taiwan wild species (C. formosensis). The result of genetic diversity analysis revealed that both sinensis (0.44) and assamica (0.41) types had higher genetic diversity than wild species (0.25). The close genetic distance between the first (Chin-Shin-Oolong) and the third (Shy-Jih-Chuen) prevailing cultivars was found, and many recently released varieties are the descents of Chin-Shin-Oolong. This implies the potential risk of genetic vulnerability for tea cultivation in Taiwan. We have successfully developed a tool for tea germplasm discrimination and genetic

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).

To assess the cross cultural-adaptations of the Roland Morris Disability Questionnaire (RMDQ). English and Chinese databases were searched through December 2017. Cross-cultural adaptation and measurement properties were evaluated using the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and the Quality Criteria for Psychometric Properties of Health Status Questionnaire. Among 34 studies, there were 31 RMDQ adaptations for 26 different languages/cultures. In the cross-cultural adaptation process, few studies reported expert committees completely constituted (3/31), and only ten studies complete the test of the pre-final version (10/31) due to insufficient sample sizes. As for the measurement properties, content validity (31/31) and construct validity (24/31) were assessed in most of the adaptations, whereas internal consistency (0/31), agreement (5/31), responsiveness (3/31), interpretability (6/31), and floor and ceiling effects (6/31) were not. The Hungarian and Moon's Korean adaptations were the highest quality translations. Where there were multiple adaptations for a language/culture, the Moon's Korean and Fan's simplified Chinese-Chinese Mainland adaptations are recommended over the other Korean or simplified Chinese-Chinese Mainland adaptations. Further studies are required to fully assess the measurement properties of the Arabic-Moroccan, Arabic-Tunisian, German- Austrian, Greek, Guajarati, Kim's Korean, Persian-Iranian, Polish, He's simplified Chinese-Chinese Mainland, Spanish, Spanish-Chilean, Thai, traditional Chinese-Taiwan, and Turkish adaptations of the RMDQ.

The Roland-Morris Disability Questionnaire (RMDQ) is a reliable tool for evaluating disability in patients with back pain, but no Korean version has been published and validated. We developed a cross-culturally adapted Korean version of the RMDQ (RMDQ-K) and validated its use for assessing disability in Korean patients with low back pain. Two hundred thirty-one patients with low back pain were assessed using the RMDQ-K, visual analog scale (VAS) during rest and activity, and the Oswestry Disability Index (ODI). The results of 40 patients were used to evaluate the test-retest reliability. The correlations of the RMDQ-K with the VAS and ODI were used to assess validity. The reliability of the RMDQ-K estimated using the internal consistency reached a Cronbach's alpha of 0.893. Test-retest trials showed a high intraclass correlation coefficient of 0.837 (95% CI 0.833-0.953). The RMDQ-K was significantly correlated with the ODI (r=0.738) and VAS during rest (r=0.450) and activity (r=0.412). This study demonstrates that the RMDQ-K is a reliable, valid instrument for measuring of disability in Korean patients with low back pain.

Numb chin syndrome (NCS) or mental neuropathy (MN) is a disorder characterized by sensory neuropathy on the distribution of the inferior alveolar nerve or mental nerve. The most frequent causes are of odontogenic origin (infections, wrong therapies). Other etiologies are related to primary tumor, metastasis, osteoradionecrosis and medication-related osteonecrosis of the jaw (MRONJ). The aim of this study is to highlight the clinical importance of NCS as one of the first symptoms of cancer or as consequence of drug therapy. The present study was conducted from 2010 to 2016 by recruiting patients who present NCS as one of the symptoms, having excluded those in which it depends on a clear odontogenic cause, on systemic degenerative diseases or metabolic disorders. Data collection included suspected diagnosis at the time of presentation of the symptom, final diagnosis, mandibular localization, treatment performed and diagnostic delay between the first medical examination and the definitive diagnosis. This study included 29 patients in which NCS had not a clear odontogenic cause. NCS was the first symptom of malignancy in 11 cases and the clinical sign of metastasis in 4 cases. In a single patient, it was the first symptom of an immune-mediated disease. In the remaining 13 patients, NCS represented the symptom of MRONJ. NCS can be the first symptom of malignancy, especially in patients with a previous history of cancer, but also a prodromal sign of MRONJ. It should be recognized in order to require deeper examinations for early diagnosis of the disease. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

A translation, cross-cultural adaptation, and psychometric analysis. The aim of this study was to translate, cross-culturally adapt, and validate the Yoruba version of the RMDQ. The Roland-Morris Disability Questionnaire (RMDQ) is a valid outcome tool for low back pain (LBP) in clinical and research settings. There seems to be no valid and reliable version of the RMDQ in the Nigerian languages. Following the Guillemin criteria, the English version of the RMDQ was forward and back translated. Two Yoruba translated versions of the RMDQ were assessed for clarity, common language usage, and conceptual equivalence. Consequently, a harmonized Yoruba version was produced and was pilot-tested among 20 patients with nonspecific long-term LBP (NSLBP) for cognitive debriefing. The final version of the Yoruba RMDQ was tested for its construct validity and re-retest reliability among 120 and 87 patients with NSLBP, respectively. Pearson product moment correlation coefficient (r) of 0.82 was obtained for reliability of the Yoruba version of the RMDQ. The test-retest reliability of the Yoruba RMDQ yielded Cronbach alpha 0.932, while the intraclass correlation (ICC) ranged between 0.896 and 0.956. The analysis of the global scores of both the English and Yoruba versions of the RMDQ yielded ICC value of between 0.995 (95% confidence interval 0.996-0.997), with the item-by-item Kappa agreement ranging between 0.824 and 1.000. The external validity of RMDQ using Quadruple Visual Analogue Scale was r = -0.596 (P = 0.001). The Yoruba version of the RMDQ had no floor/ceiling effects, as no patient achieved either of the maximum or the minimum possible scores. The Yoruba version of the RMDQ has excellent reliability and validity and may be an appropriate outcome tool for clinical and research purposes among Yoruba-speaking patients with LBP. 3.

Benign rolandic epilepsy (BRE) is a form of partial idiopathic epilepsy according to the International League Against Epilepsy (ILAE) syndromes classification (1989). Recent studies have identified cases of BRE that do not meet the initial definition of 'benign'; these included reports of cases with specific cognitive deficits. It is still a matter of debate, whether these deficits are due to epilepsy per se, to treatment or other associated factors. The aim of this study was to evaluate if BRE children have cognitive deficits at the onset of their seizures, prior to their participation in any anti-epileptic drug therapy (AED). We performed a neuropsychological assessment of 18 BRE children compared with a corresponding age-matched control group. We used the Cambridge Neuropsychological Test Automated Battery (CANTAB). Subjects were at their first neurological evaluation, before any AED therapy. We assessed: visual memory, induction and executive functions. In our group, the BRE children performed comparably with the control children for the induction and executive functions. Substantial differences were identified for the visual memory subtests: PRM percent correct (t = -2.58, p = 0.01) and SRM percent correct (t = -2.73, p = 0.01). Age of seizure onset had a negative impact on the visual memory subtest performances (PRM mean correct latency). We found significant correlations between the different CANTAB subtests results and characteristics of the centrotemporal spikes (CTS). Our results are consistent with the findings of other similar studies. This form of epilepsy is associated with subtle neuropsychological deficits, present at seizure onset. Neuropsychological deficits identified, suggest a more diffuse brain involvement in the epileptiform process.

The effects of salinity on the expression of genes coding for growth hormone (GH) and prolactin-1 (PRL1) were studied in various natural populations of the black-chinned tilapia Sarotherodon melanotheron from West Africa. Individuals were sampled in June 2005 in six locations in Senegal and the Gambia, at various salinities between 0 and 101. The poorest condition factors were recorded in the most saline sampling site and the best growth in the fish from a marine environment. The pituitary GH mRNA levels were significantly higher in fish adapted to seawater, whereas the PRL1 mRNA levels were highest in fish adapted to fresh- and brackish water. These results show that the PRL1 mRNA levels seem to reflect relatively well the differences in environmental salinity, in contrast to those of GH, which would tend instead to reflect the individual growth in each environment. However, no relation could be found between growth in the hypersaline areas and the expression profile of GH. Although the fish analysed were morphologically identical, the expression of genes coding for GH and PRL1 showed large differences between individuals. This inter-individual variation in gene expression remains poorly understood.

Rolandic epilepsy (RE) is the most common genetic childhood epilepsy, consisting of focal, nocturnal seizures and frequent neurodevelopmental impairments in speech, language, literacy and attention. A complex genetic aetiology is presumed in most, with monogenic mutations in GRIN2A accounting for >5% of cases. To identify rare, causal CNV in patients with RE. We used high-density SNP arrays to analyse the presence of rare CNVs in 186 patients with RE from the UK, the USA, Sardinia, Argentina and Kerala, India. We identified 84 patients with one or more rare CNVs, and, within this group, 14 (7.5%) with recurrent risk factor CNVs and 15 (8.0%) with likely pathogenic CNVs. Nine patients carried recurrent hotspot CNVs including at 16p13.11 and 1p36, with the most striking finding that four individuals (three from Sardinia) carried a duplication, and one a deletion, at Xp22.31. Five patients with RE carried a rare CNV that disrupted genes associated with other epilepsies ( KCTD7 , ARHGEF15 , CACNA2D1, GRIN2A and ARHGEF4 ), and 17 cases carried CNVs that disrupted genes associated with other neurological conditions or that are involved in neuronal signalling/development. Network analysis of disrupted genes with high brain expression identified significant enrichment in pathways of the cholinergic synapse, guanine-exchange factor activation and the mammalian target of rapamycin. Our results provide a CNV profile of an ethnically diverse cohort of patients with RE, uncovering new areas of research focus, and emphasise the importance of studying non-western European populations in oligogenic disorders to uncover a full picture of risk variation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Cross-cultural translation, adaptation, and psychometric testing. To cross-culturally translate and adapt the Roland-Morris Disability Questionnaire (RMDQ) into Modern Standard Arabic and examine its validity with Arabic-speaking patients with low back pain (LBP). The English RMDQ is valid, reliable, and commonly used to assess LBP disability in clinical practice and research. There is no valid and reliable version of the RMDQ in Modern Standard Arabic. The RMDQ was forward translated and back translated. An expert committee of musculoskeletal physiotherapists reviewed the translation. Eight patients with LBP evaluated item-by-item comprehensibility. Ten patients piloted the RMDQ for overall comprehensibility and acceptability. Seventeen bilingual patients tested the agreement of the Arabic and English RMDQs. Two-hundred one patients completed the RMDQ and the visual analogue scale. Sixty-four patients were followed-up for test-retest reliability. Translation of most items was uncontroversial. The expert committee found the Arabic RMDQ clinically and culturally appropriate. They reviewed item 11, addressing bending and kneeling, because this has a clinical significance and cultural/religious implication regarding prayer positions. All patients reported that it was easy to understand and complete. The Arabic RMDQ had high overall agreement with the English RMDQ for the global score (intraclass correlation coefficient [ICC] = 0.925; 0.811-0.972). Kappa statistics showed good item-by-item agreement (none ≤0.30). Mean (SD) RMDQ and visual analog scale scores of 201 patients were 10.53 (4.80) and 5.11 (2.28), respectively. The RMDQ had a low correlation against pain intensity (r = 0.259; P < 0.01). A Cronbach α of 0.729 showed high internal consistency. Test-retest reliability of the Arabic RMDQ was good (ICC = 0.900; 95% confidence interval, 0.753-0.951). Kappa statistics were high for 18 items and fair for 6. The Arabic version of the RMDQ has good

PAR-2, LGL-1 and the CDC-42 GAP CHIN-1 act in distinct pathways to maintain polarity in the C. elegans embryo

In the one-cell C. elegans embryo, polarity is maintained by mutual antagonism between the anterior cortical proteins PAR-3, PKC-3, PAR-6 and CDC-42, and the posterior cortical proteins PAR-2 and LGL-1 on the posterior cortex. The mechanisms by which these proteins interact to maintain polarity are incompletely understood. In this study, we investigate the interplay among PAR-2, LGL-1, myosin, the anterior PAR proteins and CDC-42. We find that PAR-2 and LGL-1 affect cortical myosin accumulation by different mechanisms. LGL-1 does not directly antagonize the accumulation of cortical myosin and instead plays a role in regulating PAR-6 levels. By contrast, PAR-2 likely has separate roles in regulating cortical myosin accumulation and preventing the expansion of the anterior cortical domain. We also provide evidence that asymmetry of active CDC-42 can be maintained independently of LGL-1 and PAR-2 by a redundant pathway that includes the CDC-42 GAP CHIN-1. Finally, we show that, in addition to its primary role in regulating the size of the anterior cortical domain via its binding to PAR-6, CDC-42 has a secondary role in regulating cortical myosin that is not dependent on PAR-6.

Cognitive and behavioral comorbidities in Rolandic epilepsy and their relation with default mode network's functional connectivity and organization.

Rolandic epilepsy (RE) is characterized by typical interictal-electroencephalogram (EEG) patterns mainly localized in centrotemporal and parietooccipital areas. An aberrant intrinsic organization of the default mode network (DMN) due to repeated disturbances from spike-generating areas may be able to account for specific cognitive deficits and behavioral problems in RE. The aim of the present study was to investigate cognitive development (CD) and socioemotional development (SED) in patients with RE during active disease in relation to DMN connectivity and network topology. In 10 children with RE and active EEG, CD was assessed using the Wechsler Intelligence Scale for Children-IV (WISC-IV); SED was assessed using the Fünf-Faktoren-Fragebogen für Kinder (FFFK), a Big-Five inventory for the assessment of personality traits in children. Functional connectivity (FC) in the DMN was determined from a 15-minute resting state functional magnetic resonance imaging (fMRI), and network properties were calculated using standard graph-theoretical measures. More severe deficits of verbal abilities tended to be associated with an earlier age at epilepsy onset, but were not directly related to the number of seizures and disease duration. Nonetheless, at the network level, disease duration was associated with alterations of the efficiency and centrality of parietal network nodes and midline structures. Particularly, centrality of the left inferior parietal lobe (IPL) was found to be linked with CD. Reduced centrality of the left IPL and alterations supporting a rather segregated processing within DMN's subsystems was associated with a more favorable CD. A more complicated SED was associated with high seizure frequency and long disease duration, and revealed links with a less favorable CD. An impaired CD and - because of their interrelation - SED might be mediated by a common pathomechanism reflected in an aberrant organization, and thus, a potential functional deficit of the DMN

Comparative Analysis of Reproductive Traits in Black-Chinned Tilapia Females from Various Coastal Marine, Estuarine and Freshwater Ecosystems

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

Benign rolandic epilepsy of childhood (BERS) is an epilepsy syndrome with presumably genetic-developmental etiology. The pathological basis of this syndrome is completely unknown. We postulated that a developmental abnormality presumably results in abnormal EEG background activity findings. 20 children with typical BERS and an age- and sex-matched group of healthy control children underwent EEG recording and analysis. 60×2 s epochs of waking EEG background activity (without epileptiform potentials and artifacts) were analyzed in the 1-25 Hz frequency range, in very narrow bands (VNB, 1 Hz bandwidth). LORETA (Low Resolution Electromagnetic Tomography) localized multiple distributed sources of EEG background activity in the Talairach space. LORETA activity (current source density) was computed for 2394 voxels and 25 VNBs. Normalized LORETA data were processed to voxel-wise comparison between the BERS and control groups. Bonferroni-corrected p<0.05 Student's t-values were accepted as statistically significant. Increased LORETA activity was found in the BERS group (as compared to the controls) in the left and right temporal lobes (fusiform gyri, posterior parts of the superior, middle and inferior temporal gyri) and in the angular gyri in the parietal lobes, in the 4-6 Hz VNBs, mainly at 5 Hz. (1) Areas of abnormal LORETA activity exactly correspond to the temporal and parietal cortical areas that are major components of the Mirsky attention model and also the perisylvian speech network. Thus the LORETA findings may correspond to impaired attention and speech in BERS patients. (2) The LORETA findings may contribute to delineating the epileptic network in BERS. The novel findings may contribute to investigating neuropsychological disturbances and organization of the epileptic network in BERS. Copyright © 2011 Elsevier B.V. All rights reserved.

The incidence of stroke is high in China. The dysphagia caused by cerebral infarction (CI), seriously affects patients' life quality, and even endangers patients' lives. It is necessary to explore how to improve dysphagia caused by CI. To compare the effects of rehabilitation training on dysphagia and psychological state after CI between Shaker exercise and chin tuck against resistance (CTAR) exercise. Control study. Blind. Inpatients. A total of 90 patients with dysphagia after CI were divided into CTAR group, Shaker group and control group by random digit table (each group with 30 patients). Video fluoroscopic swallowing study (VFSS) and Self-Rating Depression Scale (SDS) were performed on all patients before intervention. VFSS was evaluated based on Penetration-Aspiration Scale. All patients received routine treatments including internal medicine, traditional rehabilitation training and routine nursing. The patients in control group only receive the routine treatments. Besides the routine treatments, the patients in CTAR group also received CTAR exercise, and the patients in Shaker group also received Shaker exercise. VFSS was performed again on all patients, respectively, 2, 4, and 6 weeks after exercise. SDS was performed again on all patients 6 weeks after exercise. There were no statistical differences amongst the three groups in VFSS and SDS before intervention (P>0.05). After intervention, all patients had various degrees of improvement for dysphagia in the three groups, especially between 2 and 4 weeks in CTAR and Shaker groups.

This study aimed to analyze the impacts of nutrients and related aquatic factors on changes in the Noctiluca population of the Tha Chin estuary, a nutrient-rich estuary located in the inner Gulf of Thailand. Field surveys were carried out at 30 stations during November 2009 to August 2010. The results indicated high levels of dissolved inorganic nitrogen (DIN; 13.89-46.99 μmol/L) and PO(4)(3-)-P (0.20-3.05 μmol/L) where the Noctiluca red tide occurred, particularly during the high-loading period. Dense populations were usually found in the outer part of the estuary with comparatively high salinity (25-29 psu). The highest Noctiluca density was 72,333 cells L(-1) and the cell diameters ranged between 360 and 460 μm. Proportions of small-sized cells (P(s); less than 300 μm) varied over time. In this study, P(s) showed a positive correlation with levels of PO(4)(3-)-P, while the total population density was significantly affected by levels of NH(4)(+)-N and DIN (p < 0.05). Overall, PO(4)(3-)-P influenced the development of the Noctiluca red tide, with the limitation of PO(4)(3-)-P levels to below 1 μmol/L suggested for controlling Noctiluca red tide outbreaks at their origin. To support environmental conservation and maintain sustainable production in the estuary, the levels of PO(4)(3-)-P should be considered for the further effective development of water quality standards in estuarine zones.

The purpose of this study was to determine the perceived and actual chin position(s) used for radiotherapy of head-and-neck cancers in a variety of clinical settings. Dosimetrists were asked to describe the external landmarks used to set the chin position. The lateral treatment planning radiographic figures in Ang's textbook, Radiotherapy for Head and Neck Cancers: Indications and Techniques, were analyzed for chin position by drawing a horizontal line from the tip of the chin to the cervical spine. The physicians at 7 departments were asked to rate the chin positions used in their departments for head-and-neck simulations. Choices included: (1) mildly flexed, (2) neutral, (3) mildly extended, and (4) hyperextended. In addition, each center was asked to select 2 representative cases to show routine chin position. The dosimetrists fixed the chin in neutral position by placing a virtual plane defined by 3 points (the base of the nasal septum [acanthus] and the external auditory canals) perpendicular to the table top. The type of head holder was irrelevant. Eighty-two percent (31/38) of the figures in Ang's text showed positioning in the neutral position (tip of the chin intersected the cervical spine between C2-3/C3-4). Most (71.4%) of the radiotherapists thought their patients were treated in the hyperextended neck position but, in fact, 85.7% (12/14) of the simulations showed a neural neck position. Reproducible chin positioning can be obtained by using the acanthiomeatal line. Consistent use of this technique will create a uniformly positioned set of axial co-images that have consistent appearance of avoidance and lymphatic areas. This will simplify contouring on axial computed tomography (CT) images of the neck. Standardizing the chin position is an important step to developing a standardized atlas and developing an information tool for automated contouring.

Purpose The purpose of this prospective multicenter study was to assess the accuracy of a computer-aided surgical simulation (CASS) protocol for orthognathic surgery. Materials and Methods The accuracy of the CASS protocol was assessed by comparing planned and postoperative outcomes of 65 consecutive patients enrolled from 3 centers. Computer-generated surgical splints were used for all patients. For the genioplasty, one center utilized computer-generated chin templates to reposition the chin segment only for patients with asymmetry. Standard intraoperative measurements were utilized without the chin templates for the remaining patients. The primary outcome measurements were linear and angular differences for the maxilla, mandible and chin when the planned and postoperative models were registered at the cranium. The secondary outcome measurements were: maxillary dental midline difference between the planned and postoperative positions; and linear and angular differences of the chin segment between the groups with and without the use of the template. The latter was measured when the planned and postoperative models were registered at mandibular body. Statistical analyses were performed, and the accuracy was reported using root mean square deviation (RMSD) and Bland and Altman's method for assessing measurement agreement. Results In the primary outcome measurements, there was no statistically significant difference among the 3 centers for the maxilla and mandible. The largest RMSD was 1.0mm and 1.5° for the maxilla, and 1.1mm and 1.8° for the mandible. For the chin, there was a statistically significant difference between the groups with and without the use of the chin template. The chin template group showed excellent accuracy with largest positional RMSD of 1.0mm and the largest orientational RSMD of 2.2°. However, larger variances were observed in the group not using the chin template. This was significant in anteroposterior and superoinferior directions, as in

The chin cup has been used to treat skeletal mandibular prognathism in growing patients for 200 years. The pull on the orthopedic-force chin cup is oriented along a line from the mandibular symphysis to the mandibular condyle. Various levels of success have been reported with this restraining device. The vertical chin cup produces strong vertical compression stress on the maxillary molar regions when the direction of traction is 20 degrees more vertical than the chin-condyle line. This treatment strategy may prevent relapse due to counter-clockwise rotation of the mandible. In this report, we describe a new strategy for using chin-cup therapy involving thin-plate spline (TPS) analysis of lateral cephalometric roentgenograms to visualize transformation of the mandible. The actual sites of mandibular skeletal change are not detectable with conventional cephalometric analysis. A case of mandibular prognathism treated with a chin cup and a case of dental Class III malocclusion without orthodontic treatment are described. The case analysis illustrates that specific patterns of mandibular transformation are associated with Class III malocclusion with or without orthopedic therapy, and that visualization of these deformations is feasible using TPS graphical analysis.

Treatment Approach to Severe Microgenia Cases: Combined Use of Osseous and Implant Genioplasty.

As well as the chin is an important esthetic unit of the facial structure, it is also the region having a key role in the appearance of the face. Correction of cosmetic and functional deformities that may occur in this region because of serious hypoplasia (microgenia) is performed by chin augmentation. Chin augmentation is most frequently performed via implant or osseous genioplasty in the literature. Both 2 techniques have their own advantages and disadvantages. In the literature, various studies comparing these 2 techniques and their long-term results are present, but in some severe microgenia cases, these techniques can be insufficient only for augmentation. In such cases, combined use of implant and osseous genioplasty techniques can come up and data and experiences regarding such combined uses are limited in the literature. In our study, we aim to report our experiences and long-term results regarding 3 cases to whom chin augmentation combined with implant and osseous method is applied because of serious chin hypoplasia (microgenia). Three patients to whom chin augmentation combined with osseous and implant genioplasty was applied because of severe microgenia between 2011 and 2016 are included in our study. Before the chin restoration, orthognathic surgery or maxillomandibular distraction applications owing to existing obstructive sleep apnea, malocclusion, or facial asymmetry, are performed in the patients. In preoperative period, chin augmentation amount required is planned for all the patients via cephalometric analysis and the operations of all the patients are performed under general anesthesia via intraoral access. Among 3 patients, 2 were male and 1 was female and their mean age was 27.3 years (22-33). In all the patients, primarily horizontal subapical sliding osteotomy was performed and advancement was performed. After osteotomy, mean 8-mm osseous advancement was obtained and Medpor implant was placed in the chin at the same session for additional

The global spread of Zika virus (ZIKV) and its unexpected association with congenital defects necessitates the rapid development of a safe and effective vaccine. Here we report the development and characterization of a recombinant chimeric ZIKV vaccine candidate (termed ChinZIKV) that expresses the prM-E proteins of ZIKV using the licensed Japanese encephalitis live-attenuated vaccine SA14-14-2 as the genetic backbone. ChinZIKV retains its replication activity and genetic stability in vitro, while exhibiting an attenuation phenotype in multiple animal models. Remarkably, immunization of mice and rhesus macaques with a single dose of ChinZIKV elicits robust and long-lasting immune responses, and confers complete protection against ZIKV challenge. Significantly, female mice immunized with ChinZIKV are protected against placental and fetal damage upon ZIKV challenge during pregnancy. Overall, our study provides an alternative vaccine platform in response to the ZIKV emergency, and the safety, immunogenicity, and protection profiles of ChinZIKV warrant further clinical development.

Perception of aesthetics and personality traits in orthognathic surgery patients: A comparison of still and moving images

2018-01-01

It is common in practicing orthognathic surgery to evaluate faces with retruded or protruded chins (dysgnathic faces) using photographs. Because motion may alter how the face is perceived, we investigated the perception of faces presented via photographs and videos. Two hundred naïve raters (lay persons, without maxillo facial surgery background) evaluated 12 subjects with varying chin anatomy [so-called skeletal Class I (normal chin), Class II (retruded chin), and Class III (protruded chin)]. Starting from eight traits, with Factor analysis we found a two-Factor solution, i.e. an "aesthetics associated traits cluster" and a Factor "personality traits cluster" which appeared to be uncorrelated. Internal consistency of the Factors found for photographs and videos was excellent. Generally, female raters delivered better ratings than males, but the effect sizes were small. We analyzed differences and the respective effect magnitude between photograph and video perception. For each skeletal class the aesthetics associated dimensions were rated similarly between photographs and video clips. In contrast, specific personality traits were rated differently. Differences in the class-specific personality traits seen on photographs were "smoothed" in the assessment of videos, which implies that photos enhance stereotypes commonly attributed to a retruded or protruded chin.

Discovery of a New Photometric Sub-class of Faint and Fast Classical Novae

We present photometric and spectroscopic follow-up of a sample of extragalactic novae discovered by the Palomar 60 inch telescope during a search for "Fast Transients In Nearest Galaxies" (P60-FasTING). Designed as a fast cadence (1 day) and deep (g < 21 mag) survey, P60-FasTING was particularly sensitive to short-lived and faint optical transients. The P60-FasTING nova sample includes 10 novae in M 31, 6 in M 81, 3 in M 82, 1 in NGC 2403, and 1 in NGC 891. This significantly expands the known sample of extragalactic novae beyond the Local Group, including the first discoveries in a starburst environment. Surprisingly, our photometry shows that this sample is quite inconsistent with the canonical maximum-magnitude-rate-of-decline (MMRD) relation for classical novae. Furthermore, the spectra of the P60-FasTING sample are indistinguishable from classical novae. We suggest that we have uncovered a sub-class of faint and fast classical novae in a new phase space in luminosity-timescale of optical transients. Thus, novae span two orders of magnitude in both luminosity and time. Perhaps the MMRD, which is characterized only by the white dwarf mass, was an oversimplification. Nova physics appears to be characterized by a relatively rich four-dimensional parameter space in white dwarf mass, temperature, composition, and accretion rate.

2015-07-01

Throughout literature, there are different parameters defining the ideal shape of the lip and lower third of the face. This study was conducted to clarify what it is that makes lips attractive - and whether there are gender-related differences of an attractive lip and lower third of the face. Pictures of the lip and chin region of 176 patients were photographed in a standardised way and evaluated by 250 voluntary judges through an internet presentation by means of an analogue Likert scaling system. We found a significant higher ratio of upper vermillion height/mouth-nose distance in frontal-view images of attractive compared to unattractive female (p < 0.001) and male (p < 0.05) perioral regions. Furthermore, the ratio of upper vermillion height/chin-nose distance was significantly higher in attractive than in unattractive female (p < 0.005) and male (p < 0.05) lip and chin regions. The nasolabial angle was significantly sharper in attractive compared to unattractive female perioral regions (p < 0.001). Moreover, attractive female lip and chin regions showed a wider mentolabial angle compared to unattractive female lip and chin regions (p < 0.05). Comparing men and women, we found that attractive female perioral regions showed a higher ratio of lower vermillion height/chin-mouth distance (p < 0.05) and lower vermillion height/chin-nose distance than attractive male perioral regions (p < 0.05). We were able to define certain parameters of the lip and lower third of the face that seem to add to the attractivity of female and male individuals and prove that there are gender-related differences in form and shape of an attractive lower third of the face.

Physical functioning is a core outcome domain to be measured in nonspecific low back pain (NSLBP). A panel of experts recommended the Roland-Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) to measure this domain. The original 24-item RMDQ and ODI 2.1a are recommended by their developers. The purpose of this study was to evaluate whether the 24-item RMDQ or the ODI 2.1a has better measurement properties than the other to measure physical functioning in adult patients with NSLBP. Bibliographic databases (MEDLINE, Embase, CINAHL, SportDiscus, PsycINFO, and Google Scholar), references of existing reviews, and citation tracking were the data sources. Two reviewers selected studies performing a head-to-head comparison of measurement properties (reliability, validity, and responsiveness) of the 2 questionnaires. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to assess the methodological quality of these studies. The studies' characteristics and results were extracted by 2 reviewers. A meta-analysis was conducted when there was sufficient clinical and methodological homogeneity among studies. Nine articles were included, for a total of 11 studies assessing 5 measurement properties. All studies were classified as having poor or fair methodological quality. The ODI displayed better test-retest reliability and smaller measurement error, whereas the RMDQ presented better construct validity as a measure of physical functioning. There was conflicting evidence for both instruments regarding responsiveness and inconclusive evidence for internal consistency. The results of this review are not generalizable to all available versions of these questionnaires or to patients with specific causes for their LBP. Based on existing head-to-head comparison studies, there are no strong reasons to prefer 1 of these 2 instruments to measure physical functioning in patients with NSLBP, but studies of higher

Use of simple synthetic drug called Chin – Yeh, Gold – plus – plant juice or red colloidal gold. Gold made body everlasting and the herbal principle, as soul, increased life-span. Dialectally it was called Kim – Iya. Arabicized as Al – Kimiya it finally appeared as Alchemy. Chin – Yeh as drug was only brick – red when mercury, and sulphur – with traces of gold were sublimated there resulted Chin – Tan, Gold – plus – cinnabar.

Alchemy, Chinese versus Greek, an etymological approach: a rejoinder.

PubMed

Mahdihassan, S

1988-01-01

The theory generally accepted maintains that Alchemy arose at Alexandria as a child of Greek culture. It has two names, Chemeia as the earlier and Chumeia as the later. There is another theory that Alchemy arose in China. Its founder was the aged ascetic who longed after drugs of longevity. He first tried jade, next gold and cinnabar, but the ideal was a drug which was red like cinnabar and fire-proof like gold. But what was actually prepared was red colloidal gold or "calcined gold," by grinding gold granules in a decoction of an herb of longevity. It was called Chin-I; Chin = gold and I = plant juice. In Fukin dialect Chin-I = Kim-Iya. This was Arabicized, by pre-Islamic Arabs trading in silk with China, as Kimiya, whence arose Al-Kimiya and finally Al-chemy. It was first accepted by Bucharic speaking Copts in Egypt who transliterated Kimiya = Chemeia, pronouncing it as the Arabs did. With the increase of trade in silk the Chinese also went to Alexandria and helped the Greeks to translate Chin-I as Chrusozomion meaning, gold (making) ferment, instead of gold making plant juice. Consistent with this origin of the word Chemeia is the fact that the earlier Alchemists were not Greeks but probably Bucharic speaks Copts or Egyptians. The consumer of Chin-I or Chemeia became "a drug-made immortal" called Chin-Jen, Golden-Man. This was translated into Greek as Chrusanthropos. Thus the etymoloogy of two Greek words Chrusozomion and Chrusanthropos support the origin of the loan word, Chemeia as Chinese. To save space it is not proposed to discuss the origin of Chumeia.

The majority of validation done on the Roland-Morris Disability Questionnaire (RMDQ) has been in patients with mild or moderate disability. There is paucity of research focusing on the psychometric quality of the RMDQ in patients with severe disability. To evaluate the psychometric quality of the RMDQ in patients with severe disability. Observational clinical study. The sample consisted of 214 patients with painful vertebral compression fractures who underwent vertebroplasty or kyphoplasty. The 23-item version of the RMDQ was completed at two time points: baseline and 30-day postintervention follow-up. With the two-parameter logistic unidimensional item response theory (IRT) analyses, we derived the range of scores that produced reliable measurement and investigated the minimal clinically important difference (MCID). Scores for 214 (100%) patients at baseline and 108 (50%) patients at follow-up did not meet the reliability criterion of 0.90 or higher, with the majority of patients having disability due to back pain that was too severe to be reliably measured by the RMDQ. Depending on methodology, MCID estimates ranged from 2 to 8 points and the proportion of patients classified as having experienced meaningful improvement ranged from 26% to 68%. A greater change in score was needed at the extreme ends of the score scale to be classified as having achieved MCID using IRT methods. Replacing items measuring moderate disability with items measuring severe disability could yield a version of the RMDQ that better targets patients with severe disability due to back pain. Improved precision in measuring disability would be valuable to clinicians who treat patients with greater functional impairments. Caution is needed when choosing criteria for interpreting meaningful change using the RMDQ. Copyright © 2017 Elsevier Inc. All rights reserved.

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. 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. 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). 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.

Facial Assessment and Injection Guide for Botulinum Toxin and Injectable Hyaluronic Acid Fillers: Focus on the Lower Face.

2017-09-01

This third article of a three-part series addresses techniques and recommendations for aesthetic treatment of the lower face. The lower face is considered an advanced area for facial aesthetic treatment. In this region, soft-tissue fillers play a more important role than neuromodulators and should be used first to provide structure and support before neuromodulators are considered for treatment of dynamic lines. Treatment of the lip, perioral region, and chin, in addition to maintaining balance of the lower face with the face overall, is challenging. Procedures on the lip should avoid overcorrection while respecting the projection of the lips on the profile view and the ratio of lip size to chin. The chin is often neglected, but reshaping the jawline can provide dramatic improvement in facial aesthetics. Both profile and anterior views are critical in assessment and treatment of the lower face. Finally, rejuvenation of the neck region requires fillers for structural support of the chin and jawline and neuromodulators for treatment of the masseter and platysma.

Electrical and structural properties were investigated for group-4 transition-metal nitride contacts on Ge (TiN/Ge, ZrN/Ge, and HfN/Ge), which were prepared by direct sputter depositions using nitride targets. These contacts could alleviate the intrinsic Fermi-level pinning (FLP) position toward the conduction band edge. It was revealed that this phenomenon is induced by an amorphous interlayer (a-IL) containing nitrogen atoms at the nitride/Ge interfaces. The strength of FLP alleviation positively depended on the thickness of a-IL. TiN/Ge and ZrN/Ge contacts with ∼2 nm-thick a-ILs showed strong FLP alleviations with hole barrier heights (Φ{sub BP}) in the range of 0.52–56 eV, and a HfN/Ge contactmore » with an ∼1 nm-thick a-IL showed a weaker one with a Φ{sub BP} of 0.39 eV. However, TaN/Ge contact without a-IL did not show such FLP alleviation. Based on the results of depth distributions for respective elements, we discussed the formation kinetics of a-ILs at TiN/Ge and ZrN/Ge interfaces. Finally, we proposed an interfacial dipole model to explain the FLP alleviation.« less

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. 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. 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. 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.

Can Mapping Algorithms Based on Raw Scores Overestimate QALYs Gained by Treatment? A Comparison of Mappings Between the Roland-Morris Disability Questionnaire and the EQ-5D-3L Based on Raw and Differenced Score Data.

Mapping algorithms are increasingly being used to predict health-utility values based on responses or scores from non-preference-based measures, thereby informing economic evaluations. We explored whether predictions in the EuroQol 5-dimension 3-level instrument (EQ-5D-3L) health-utility gains from mapping algorithms might differ if estimated using differenced versus raw scores, using the Roland-Morris Disability Questionnaire (RMQ), a widely used health status measure for low back pain, as an example. We estimated algorithms mapping within-person changes in RMQ scores to changes in EQ-5D-3L health utilities using data from two clinical trials with repeated observations. We also used logistic regression models to estimate response mapping algorithms from these data to predict within-person changes in responses to each EQ-5D-3L dimension from changes in RMQ scores. Predicted health-utility gains from these mappings were compared with predictions based on raw RMQ data. Using differenced scores reduced the predicted health-utility gain from a unit decrease in RMQ score from 0.037 (standard error [SE] 0.001) to 0.020 (SE 0.002). Analysis of response mapping data suggests that the use of differenced data reduces the predicted impact of reducing RMQ scores across EQ-5D-3L dimensions and that patients can experience health-utility gains on the EQ-5D-3L 'usual activity' dimension independent from improvements captured by the RMQ. Mappings based on raw RMQ data overestimate the EQ-5D-3L health utility gains from interventions that reduce RMQ scores. Where possible, mapping algorithms should reflect within-person changes in health outcome and be estimated from datasets containing repeated observations if they are to be used to estimate incremental health-utility gains.

The demand of power is increasing day by day due to the increase of world population as well as the industrialization and modernization. Depletion of the world's fossil fuel reserves and the adverse effects of their uses on the environment insist the researchers to find out some means of efficient and cost effective alternative energy sources from small to large scales. In a gymnasium the human metabolism power is used to drive the physical exercise devices. However there are a number of exercise device which can have the potential to generate electricity during physical exercise. By converting the available mechanical energy from these exercise devices into kinetic energy, electric power can be produced. In this work, energy was harvested from the most commonly used physical exercise devices used in the gymnasium - paddling and chin up. The paddle pulley and the chin up pulley were connected to the couple pulley which in turn coupled to an alternator by a V-belt to produce electrical energy and a rechargeable battery was used to store electrical energy. The power generation from the device depends upon the speed at which the alternator runs and the age limit. The electrical energy output was observed 83.6 watt at 1300 rpm and 62.5 watt at1150 rpm alternator speed for the paddling and chin up respectively recorded for an average adult. The device was designed for a constant 49N load on the alternator for both paddling and chin up operation. By running each of these devices for about 12 hours in a day, any gymnasium can avoid burning of almost 23.67 kg and 31.6 kg of diesel fuel per year for chin up and paddling respectively. Also it can cut off the CO2 emission to the environment which reveals itself a standalone green micro gym.

Oral-Facial Tissue Reconstruction in the Regenerative Axolotl.

2016-12-01

Absence of large amounts of orofacial tissues caused by cancerous resections, congenital defects, or trauma results in sequelae such as dysphagia and noticeable scars. Oral-neck tissue regeneration was studied in the axolotl (regenerative amphibian) following a 2.5-mm punch biopsy that simultaneously removed skin, connective tissue, muscle, and cartilage in the tongue and intermandibular region. The untreated wound was studied macroscopically and histologically at 17 different time points ranging from 0 to180 days (N = 120 axolotls). At 12 hr, the wound's surface was smoothened and within 1mm, internal lingual muscular modifications occurred; at the same distance, between days 4-7 lingual muscle degradation was complete. Immunofluorescence indicates complete keratinocytes migration by 48 hr. These cells with epidermal Leydig cells, appearing yellow, lead the chin's deep tissue outgrowth until its closure on the 14th day. Regeneration speeds varied and peaked in time for each tissue, (1) deep chin 84.3 μm/hr from 24 to 96 hr, (2) superficial chin 71.1 μm/hr from 7-14 days, and (3) tongue 86.0 μm/hr between 48 hr and 7 days. Immunofluorescence to Col IV showed basement membrane reconnected between days 30-45 coinciding with the chin's dermal tissue's surface area recovery. New muscle appeared at 21 days and was always preceded by the formation of a collagen bed. Both chin tissues regain all surface area and practically all components while the lingual structure lacks some content but is generally similar to the original. The methodology and high-resolution observations described here are the first of its kind for this animal model and could serve as a basis for future studies in oral and facial regenerative research. © 2017 Wiley Periodicals, Inc.

To estimate the efficacy of traditional Chinese medicine (Chining decoction, CHIN) for radiation-induced oral mucositis in patients with head and neck cancer. From May 2014 to December 2015, 70 consecutive patients were randomly assigned to receive CHIN (treatment group) or recombinant human epidermal growth factor (rhEGF) spray (control group) at a 1:1 ratio. CHIN was administered to treatment group from the first day of radiotherapy until the completion of radiotherapy. Simultaneously, the rhEGF spray was administered to control group on the oral mucosa of irradiated area. The clinical benefit was determined by gradation of mucositis (Common Terminology Criteria for Adverse Events v4.0), oral pain, and xerostomia (visual analysis scale) for each week during radiotherapy. Body mass index was evaluated before and after radiotherapy. Patients in the treatment group had prominent remission of oral pain and grade of mucositis on each observing point compared with those in control group ( P < .01). Xerostomia was decreased notably in treatment group compared with control group ( P < .01). Body mass index in the treatment group exhibited advantage over control group after radiotherapy, but there was no statistical significance (19.8 ± 3.26 vs 18.8 ± 2.5 kg/m 2 , P = .153, >.05). CHIN presented an obvious advantage in preventing radiation-induced oral mucositis compared with rhEGF spray.

A decentralized software bus based on IP multicas ting

NASA Technical Reports Server (NTRS)

Callahan, John R.; Montgomery, Todd

1995-01-01

We describe decentralized reconfigurable implementation of a conference management system based on the low-level Internet Protocol (IP) multicasting protocol. IP multicasting allows low-cost, world-wide, two-way transmission of data between large numbers of conferencing participants through the Multicasting Backbone (MBone). Each conference is structured as a software bus -- a messaging system that provides a run-time interconnection model that acts as a separate agent (i.e., the bus) for routing, queuing, and delivering messages between distributed programs. Unlike the client-server interconnection model, the software bus model provides a level of indirection that enhances the flexibility and reconfigurability of a distributed system. Current software bus implementations like POLYLITH, however, rely on a centralized bus process and point-to-point protocols (i.e., TCP/IP) to route, queue, and deliver messages. We implement a software bus called the MULTIBUS that relies on a separate process only for routing and uses a reliable IP multicasting protocol for delivery of messages. The use of multicasting means that interconnections are independent of IP machine addresses. This approach allows reconfiguration of bus participants during system execution without notifying other participants of new IP addresses. The use of IP multicasting also permits an economy of scale in the number of participants. We describe the MULITIBUS protocol elements and show how our implementation performs better than centralized bus implementations.

Technical Knowledge, Cultural Practices and Social Boundaries: Wan-Nan Scholars and the Recasting of Jesuit Astronomy, 1600-1800

NASA Astrophysics Data System (ADS)

Chu, Ping-Yi.

Taking four Wan-nan Confucian scholars--Yang Kuang -hsien, Mei Wen-ting, Chiang Yung and Tai Chen--as examples, this dissertation studies how an immigrant Jesuit scientific community built and defended itself in a specialized institutional niche located at the Ch'ing court and how a defeated Chinese scientific tradition successfully survived by occupying a broader cultural space, with the Manchu emperor in between. Special attention is paid to how these four Confucian scholars constructed social boundaries between the Chinese and the Westerners in their astronomical discourses and how they domesticated Western astronomy in order to fit the Chinese cultural conditions situated in the power structure built by the Manchus. This inquiry begins with a brief introduction of Wan-nan and the Wan-nan school. I then discuss how the Jesuits legitimated their knowledge during the Ming -Ch'ing transition, and how Jesuit astronomy was situated within the power nexus between the Confucian literati and the emperors. The next chapter focuses on Yang Kuang-hsien and his challenges to the Jesuits. I examine his strategies and the power structure in which Yang carried out his challenge to the Jesuits. The fourth and fifth chapters investigate how Mei Wen-ting restructured the relationship between Confucianism and astronomy. The former chapter focuses on Mei's social networking and his ambivalence towards the Ming and Ch'ing dynasties, on the one hand, and towards Chinese and Western learning on the other. The latter chapter deals with how Mei Wen-ting recast Chinese astronomical tradition and Confucianism. In the sixth chapter, I will compare the fame of Chiang Yung and Tai Chen in order to demonstrate how astronomy was practiced in evidential studies after Mei Wen-ting, and how evidential studies itself conveyed an ideological construction of the other.

Mandibular fractures are rare in children. Symptoms of these fractures include preauricular pain and swelling, trismus and pain when opening the mouth, and they are often preceded by a fall on the chin. If the diagnosis is missed they may have serious consequences for the growth and development of the jaw. A 3-year-old boy was referred with a swelling in his left cheek, fever and vomiting. Two days earlier he had fallen on his chin. At physical examination he had severe preauricular pain on palpation and a trismus. The patient was admitted because of suspicion of a viral parotitis and the threat of dehydration. After discharge, he went to the dentist for examination of a molar that was painful to the touch. The dentist performed an orthopantomogram and discovered a fracture of the left mandibular collum. Any child with trauma to the chin should be observed for symptoms of a mandibular fracture, and if it seems necessary non-invasive radiographic examination should be performed.

The Cortical Connectivity of the Prefrontal Cortex in the Monkey Brain

PubMed Central

Yeterian, Edward H.; Pandya, Deepak N.; Tomaiuolo, Francesco; Petrides, Michael

2011-01-01

One dimension of understanding the functions of the prefrontal cortex is knowledge of cortical connectivity. We have surveyed three aspects of prefrontal cortical connections: local projections (within the frontal lobe), the termination patterns of long association (post-Rolandic) projections, and the trajectories of major fiber pathways. The local connections appear to be organized in relation to dorsal (hippocampal origin) and ventral (paleocortical origin) architectonic trends. According to the proposal of a dual origin of the cerebral cortex, cortical areas can be traced as originating from archicortex (hippocampus) on the one hand, and paleocortex, on the other hand, in a stepwise manner (e.g., Sanides, 1969; Pandya and Yeterian, 1985). Prefrontal areas within each trend are connected with less architectonically differentiated areas, and, on the other hand, with more differentiated areas. Such organization may allow for the systematic exchange of information within each architectonic trend. The long connections of the prefrontal cortex with post-Rolandic regions seem to be organized preferentially in relation to dorsal and ventral prefrontal architectonic trends. Prefrontal areas are connected with post-Rolandic auditory, visual and somatosensory association areas, and with multimodal and paralimbic regions. This long connectivity likely works in conjunction with local connections to serve prefrontal cortical functions. The afferent and efferent connections of the prefrontal cortex with post-Rolandic regions are conveyed by specific long association pathways. These pathways as well appear to be organized in relation to dorsal and ventral prefrontal architectonic trends. Finally, although prefrontal areas have preferential connections in relation to dual architectonic trends, it is clear that there are interconnections between and among areas in each trend, which may provide a substrate for the overall integrative function of the prefrontal cortex.

2007-12-01

Understanding the ground level ozone regional background characteristics is essential in understanding the contribution of long-range transport of pollutants from Asia Mainland to air quality in downwind areas. In order to understand this characteristic in north-west Pacific Rim, we conducted a coupled study using ozone observation from regional background stations and 3-D regional-scale chemical transport model simulations. We used O3, CO, wind speed and wind direction data from two regional background stations and ¡§other stations¡¨ over a ten year period and organized several numerical experiments to simulate one spring month in 2003 to obtain a deeper understanding. The so called ¡§other stations¡¨ had actually been named as background stations under various governmental auspices. But we found them to be often under strong influence of local pollution sources with strong diurnal or slightly longer time variations. We found that the Yonagunijima station (24.74 N, 123.02 E) and Heng-Chuen station (21.96 N,120.78 E), about a distance of 400 km apart, have almost the same ozone time series pattern. For these two stations in 2003, correlation coefficients (R2) for annual observed ozone concentration is about 0.64, in the springtime it is about 0.7, and in a one-month period at simulation days it is about 0.76. These two stations have very little small scale variations in all the variables studied. All variations are associated with large scale circulation changes. This is especially so at Yonagunijima station. Using a 3-D regional-scale chemical transport model for East Asia region including contribution from Asia continental outflow and neighboring island pollution areas we found that the Yonagunijima and HengChuen station are indeed free of pollutants from all neighboring areas keeping in mind that pollutants from Taiwan area is never far away. Ozone concentrations in these two stations are dominated by synoptic scale weather patterns, with diffused

Transsexualism is a gender identity disorder in which there is a strong desire to live and be accepted as a member of the opposite sex. In male-to-female transsexuals with strong masculine facial features, facial feminization surgery is performed as part of the gender reassignment. A strong association between femininity and attractiveness has been attributed to the upper third of the face and the interplay of the glabellar prominence of the forehead. Studies have shown that a certain lower jaw shape is characteristic of males with special attention to the strong square mandibular angle and chin and also suggest that the attractive female jaw is smaller with a more round shape mandibular angles and a pointy chin. Other studies have shown that feminization of the forehead through cranioplasty have the most significant impact in determining the gender of a patient. Facial feminization surgeries are procedures aimed to change the features of the male face to that of a female face. These include contouring of the forehead, brow lift, mandible angle reduction, genioplasty, rhinoplasty and a variety of soft tissue adjustments. In our maxillofacial surgery department at the Sheba Medical Center we perform forehead reshaping combining with brow lift and at the same surgery, mandibular and chin reshaping to match the remodeled upper third of the face. The forehead reshaping is done by cranioplasty with additional reduction of the glabella area by burring of the frontal bone. After reducing the frontal bossing around the superior orbital rims we manage the soft tissue to achieve the brow lift. The mandibular reshaping, is performed by intraoral approach and include contouring of the angles by osteotomy for a more round shape (rather than the manly square shape angles), as well as reshaping of the bone in the chin area in order to make it more pointy, by removing the lateral parts of the chin and in some cases performing also genioplasty reduction by AP osteotomy.

Necrotizing Lip Infection Causing Septic Thrombophlebitis of the Neck: A Rare Variant of Lemierre Syndrome.

PubMed

Cuddy, Karl; Saadat, Nariman; Khatib, Baber; Patel, Ashish

2018-01-01

Lemierre syndrome is an uncommon condition in which internal jugular vein thrombosis presents after recent oropharyngeal infection. Frequently, this is accompanied by septic emboli. This report outlines a variant of this disease process, with septic thrombophlebitis of the neck associated with a necrotizing skin infection of the lower lip and chin. A 25-year-old man with lower lip and chin swelling, initially managed with intravenous antibiotics, progressed to the development of a left facial vein thrombus, septic emboli to the lungs, and a necrotizing lower lip and chin infection that was managed with debridement, thrombectomy, and prolonged hemodynamic and pulmonary support. A necrotizing skin infection with thrombus of the jugular system and septic emboli is a very rare variant of Lemierre syndrome. Early recognition of an infection with septic emboli and/or necrotizing pathobiological findings allows for prompt antibiotic and surgical therapy, minimizing the mortality of these potentially lethal infections.

Teaghrelins are unique acylated flavonoid tetraglycosides found in Chin-shin oolong tea, and have been demonstrated to be promising oral ghrelin analogues. The biosynthetic pathway of teaghrelins from quercetin-3-O-rutinoside (rutin) or kaempferol-3-O-rutinoside (nicotiflorin) was proposed to comprise three enzymatic steps according to the identification of putative intermediates in Chin-shin oolong tea. In addition to the two known teaghrelins in Chin-shin oolong tea, four teaghrelin-like compounds with different attachments of glycosides were identified in various oolong teas. Molecular modeling and docking were used to evaluate theoretically whether the putative biosynthetic intermediates of teaghrelins and the four teaghrelin-like compounds could be potential candidates of ghrelin analogues. The results showed that the attachment of a coumaroyl group was crucial for these tea compounds to bind to the ghrelin receptor. However, the additional attachment of a rhamnosyl glycoside to the flavonoid backbone of teaghrelin-like compounds at C-7 significantly reduced their binding affinity with the ghrelin receptor.

The influence of resistance training experience on the between-day reliability of commonly used strength measures in male youth athletes. J Strength Cond Res 31(7): 2005-2010, 2017-The purpose of this study was to determine the between-day reliability of commonly used strength measures in male youth athletes while considering resistance training experience. Data were collected on 25 male athletes over 2 testing sessions, with 72 hours rest between, for the 3 repetition maximum (3RM) front squat, chin-up, and bench press. Subjects were initially categorized by resistance training experience (inexperienced; 6-12 months, experienced; >2 years). The assessment of the between-day reliability (coefficient of variation [CV%]) showed that the front squat (experienced: 2.90%; inexperienced: 1.90%), chin-up (experienced: 1.70%; inexperienced: 1.90%), and bench press (experienced: 4.50%; inexperienced: 2.40%) were all reliable measures of strength in both groups. Comparison between groups for the error of measurement for each exercise showed trivial differences. When both groups were combined, the CV% for the front squat, bench press, and chin-up were 2.50, 1.80, and 3.70%, respectively. This study provides scientists and practitioners with the between-day reliability reference data to determine real and practical changes for strength in male youth athletes with different resistance training experience. Furthermore, this study demonstrates that 3RM front squat, chin-up, and bench press are reliable exercises to quantify strength in male youth athletes.

Facial profile parameters and their relative influence on bilabial prominence and the perceptions of facial profile attractiveness: A novel approach

Denize, Erin Stewart; McDonald, Fraser; Sherriff, Martyn

2014-01-01

Objective To evaluate the relative importance of bilabial prominence in relation to other facial profile parameters in a normal population. Methods Profile stimulus images of 38 individuals (28 female and 10 male; ages 19-25 years) were shown to an unrelated group of first-year students (n = 42; ages 18-24 years). The images were individually viewed on a 17-inch monitor. The observers received standardized instructions before viewing. A six-question questionnaire was completed using a Likert-type scale. The responses were analyzed by ordered logistic regression to identify associations between profile characteristics and observer preferences. The Bayesian Information Criterion was used to select variables that explained observer preferences most accurately. Results Nasal, bilabial, and chin prominences; the nasofrontal angle; and lip curls had the greatest effect on overall profile attractiveness perceptions. The lip-chin-throat angle and upper lip curl had the greatest effect on forehead prominence perceptions. The bilabial prominence, nasolabial angle (particularly the lower component), and mentolabial angle had the greatest effect on nasal prominence perceptions. The bilabial prominence, nasolabial angle, chin prominence, and submental length had the greatest effect on lip prominence perceptions. The bilabial prominence, nasolabial angle, mentolabial angle, and submental length had the greatest effect on chin prominence perceptions. Conclusions More prominent lips, within normal limits, may be considered more attractive in the profile view. Profile parameters have a greater influence on their neighboring aesthetic units but indirectly influence related profile parameters, endorsing the importance of achieving an aesthetic balance between relative prominences of all aesthetic units of the facial profile.

Resuscitation guidelines endorse unconscious and normally breathing out-of-hospital victims to be placed in the recovery position to secure airway patency, but recently a debate has been opened as to whether the recovery position threatens the cardiac arrest victim's safety assessment and delays the start of cardiopulmonary resuscitation. To compare the assessment of the victim's breathing arrest while placed in the recovery position versus maintaining an open airway with the continuous head tilt and chin lift technique to know whether the recovery position delays the cardiac arrest victim's assessment and the start of cardiopulmonary resuscitation. Basic life support-trained university students were randomly divided into two groups: one received a standardized cardiopulmonary resuscitation refresher course including the recovery position and the other received a modified cardiopulmonary resuscitation course using continuous head tilt and chin lift for unconscious and spontaneously breathing patients. A human simulation test to evaluate the victim's breathing assessment was performed a week later. In total, 59 participants with an average age of 21.9 years were included. Only 14 of 27 (51.85%) students in the recovery position group versus 23 of 28 (82.14%) in the head tilt and chin lift group p=0.006 (OR 6.571) detected breathing arrest within 2min. The recovery position hindered breathing assessment, delayed breathing arrest identification and the initiation of cardiac compressions, and significantly increased the likelihood of not starting cardiopulmonary resuscitation when compared to the results shown when the continuous head tilt and chin lift technique was used.

Topography of itch: evidence of distinct coding for pruriception in the trigeminal nerve

PubMed Central

Andersen, Hjalte H.; Elberling, Jesper; Lo Vecchio, Silvia

2017-01-01

Introduction: Little is known about the topographical distribution of pruriception (in particular for nonhistaminergic itch), although conditions with chronic itch frequently occur in distinct anatomic and often bilateral patterns. This study aimed to investigate regional differences in the sensitivity to itch stimuli by assessing the intensity of itch, pain, and cutaneous neurogenic flare evoked by histamine and cowhage in different anatomic regions in 20 healthy volunteers. Methods: Itch was induced by 1% histamine applied with a prick lancet or by insertion of 25±5 cowhage spicules in 4 regions: volar/dorsal forearm, lower back, and chin. The duration and intensity of itch and pain following each pruritic stimulus were measured by a continuous visual analogue scale (VAS0-100). Sensitivity to touch-evoked itch was assessed by von Frey filaments and cutaneous flare was quantified by full-field laser perfusion imaging. Results: Peak itch intensity was lower at the chin (19.4±3.6) compared with other areas (mean of 3 locations; 41.3±4.4), independently of whether histamine or cowhage was applied (P<0.01). Baseline sensitivity to touch-evoked itch was higher on the chin (P<0.01), but here hyperknesis did not develop in contrast to other areas (P<0.05). Cutaneous flare was more intense but had a smaller dispersion at the chin, compared with other areas (P<0.01). Discussion: In conclusion, sensitivity to histaminergic and non-histaminergic itch diverges considerably between body regions. Lower density of pruriceptive CMH and CMI-neurons or distinct neuronal substrates for itch in the mandibular part of the trigeminal area may explain the observed reduced itch and vasomotor responses.

The Influence of Class II Division 2 Malocclusions on the Harmony of the Human Face Profile.

Perović, Tatjana

2017-11-24

BACKGROUND Persons with class II division 2 malocclusion are characterized by a very specific dento-skeletal and soft-tissue profile (a profile in which a protruding nose and chin, retruding lips, concave and shortened lower third of the face, and gummy smile are dominant), which is the opposite of the currently modern profiles (convex profile of protruding lips and small chin). The aim of this research was to determine the differences in parameters of harmonies of facial profiles between persons with class II division 2 malocclusions and class I, and to establish the significance of those differences. MATERIAL AND METHODS For this study, 50 patients with class II division 2 malocclusions and 50 patients with class I were selected; profile photos were recorded and a photometric analysis was done: a type of profile according to Schwarz, the shape of a nose, the prominence of chin, biometrical field, the position of lips in relation to the tangent Sn-Pg, S-line (Steiner), E-line (Riketts) and a facial angle according to Arnett. RESULTS The significant differences in profiles of persons with class II division 2 compared to class I were: position and prominence of the chin, the position of the lower and upper lip in relation to the S-line, and smaller value of a facial angle in relation to persons with class I. CONCLUSIONS The differences seen in skeletal profiles were not associated with significant differences in the profiled facial contours of the examined groups. The compensatory role of the fullness of soft tissues of the lips is probably the reason why there were not significant deviations in all the examined parameters.

The purpose of this study was to determine differences in preference for Korean American facial profiles among Korean American orthodontic patients with 2 levels of acculturation, Asian American orthodontists, and Caucasian orthodontists. Images of 1 male and 1 female Korean American adult were animated to move parts of the faces from an extreme retrusive position to an extreme protrusive position by using the Perceptometrics computer program. Three movies were created of the nose, lips, and chin for each image. Three groups of judges, ie, 18 Korean American orthodontic patients, 17 Asian orthodontists, and 18 Caucasian orthodontists selected the most pleasing position and the zone of acceptability as a measure of tolerance. Statistically significant differences were found between Caucasian orthodontists and Korean American orthodontic patients for the most pleasing and midpoint of acceptability positions of female nose and male chin, with no differences in the zone of acceptability position among the groups. In general, the Korean American orthodontic patients preferred a more protrusive nose on the female image and more retrusive chin on the male image than Caucasian orthodontists for the most pleasing and midpoint of acceptability positions, with similar zone of acceptability for all 3 groups.

Alteration of Occlusal Plane in Orthognathic Surgery: Clinical Features to Help Treatment Planning on Class III Patients

2018-01-01

Dentofacial deformities (DFD) presenting mainly as Class III malocclusions that require orthognathic surgery as a part of definitive treatment. Class III patients can have obvious signs such as increasing the chin projection and chin throat length, nasolabial folds, reverse overjet, and lack of upper lip support. However, Class III patients can present different facial patterns depending on the angulation of occlusal plane (OP), and only bite correction does not always lead to the improvement of the facial esthetic. We described two Class III patients with different clinical features and inclination of OP and had undergone different treatment planning based on 6 clinical features: (I) facial type; (II) upper incisor display at rest; (III) dental and gingival display on smile; (IV) soft tissue support; (V) chin projection; and (VI) lower lip projection. These patients were submitted to orthognathic surgery with different treatment plannings: a clockwise rotation and counterclockwise rotation of OP according to their facial features. The clinical features and OP inclination helped to define treatment planning by clockwise and counterclockwise rotations of the maxillomandibular complex, and two patients undergone to bimaxillary orthognathic surgery showed harmonic outcomes and stables after 2 years of follow-up.

Estimation of Delta Wave by Mutual Information of Heartbeat During Sleep

NASA Astrophysics Data System (ADS)

Kurihara, Yosuke; Watanabe, Kajiro; Kobayashi, Kazuyuki; Tanaka, Hiroshi

The quality of sleep is evaluated based on the sleep stages judged by R-K method or the manual of American Academy of Sleep Medicine. The brainwaves, eye movements, and chin EMG of sleeping subjects are used for the judgment. These methods above, however, require some electrodes to be attached to the head and the face to obtain the brainwaves, eye movements, and chin EMG, thus making the measurements troublesome to be held on a daily basis. If non-invasive measurements of brainwaves, eye movements, and chin EMG are feasible, or their equivalent data can be estimated through other bio-signals, the monitoring of the quality of daily sleeps, which influences the health condition, will be easy. In this paper, we discuss the appearance rate of delta wave occurrences, which is deeply related with the depth of sleep, can be estimated based on the average amount of mutual information calculated by pulse wave signals and body movements measured non-invasively by the pneumatic method. As a result, the root mean square error between the appearance rate of delta wave occurrences measured with a polysomnography and the estimated delta pulse was 14.93%.

Nonoperative versus operative treatment for thoracolumbar burst fractures without neurologic deficit: a meta-analysis.

Decision-making regarding nonoperative versus operative treatment of patients with thoracolumbar burst fractures in the absence of neurologic deficits is controversial. Lack of evidence-based practice may result in patients being treated inappropriately and being exposed to unnecessary adverse consequences. Using meta-analysis, we therefore compared pain (VAS) and function (Roland Morris Disability Questionnaire) in patients with thoracolumbar burst fractures without neurologic deficit treated nonoperatively and operatively. Secondary outcomes included return to work, radiographic progression of kyphosis, radiographic progression of spinal canal stenosis, complications, cost, and length of hospitalization. We searched MEDLINE, EMBASE(®), and the Cochrane Central Register of Controlled Trials for 'thoracic fractures', 'lumbar fractures', 'non-operative', 'operative' and 'controlled clinical trials'. We established five criteria for inclusion. Data extraction and quality assessment were in accordance with Cochrane Collaboration guidelines. The main analyses were performed on individual patient data from randomized controlled trials. Sensitivity analyses were performed on VAS pain, Roland Morris Disability Questionnaire score, kyphosis, and return to work, including data from nonrandomized controlled trials and using fixed effects meta-analysis. We identified four trials, including two randomized controlled trials consisting of 79 patients (41 with operative treatment and 38 with nonoperative treatment). The mean followups ranged from 24 to 118 months. We found no between-group differences in baseline pain, kyphosis, and Roland Morris Disability Questionnaire scores. At last followup, there were no between-group differences in pain, Roland Morris Disability Questionnaire scores, and return to work rates. We found an improvement in kyphosis ranging from means of 12.8º to 11º in the operative group, but surgery was associated with higher complication rates and costs

Investigation of spatial resolution improvement by use of a mouth-insert detector in the helmet PET scanner.

PubMed

Ahmed, Abdella M; Tashima, Hideaki; Yamaya, Taiga

2018-03-01

The dominant factor limiting the intrinsic spatial resolution of a positron emission tomography (PET) system is the size of the crystal elements in the detector. To increase sensitivity and achieve high spatial resolution, it is essential to use advanced depth-of-interaction (DOI) detectors and arrange them close to the subject. The DOI detectors help maintain high spatial resolution by mitigating the parallax error caused by the thickness of the scintillator near the peripheral regions of the field-of-view. As an optimal geometry for a brain PET scanner, with high sensitivity and spatial resolution, we proposed and developed the helmet-chin PET scanner using 54 four-layered DOI detectors consisting of a 16 × 16 × 4 array of GSOZ scintillator crystals with dimensions of 2.8 × 2.8 × 7.5 mm 3 . All the detectors used in the helmet-chin PET scanner had the same spatial resolution. In this study, we conducted a feasibility study of a new add-on detector arrangement for the helmet PET scanner by replacing the chin detector with a segmented crystal cube, having high spatial resolution in all directions, which can be placed inside the mouth. The crystal cube (which we have named the mouth-insert detector) has an array of 20 × 20 × 20 LYSO crystal segments with dimensions of 1 × 1 × 1 mm 3 . Thus, the scanner is formed by the combination of the helmet and mouth-insert detectors, and is referred to as the helmet-mouth-insert PET scanner. The results show that the helmet-mouth-insert PET scanner has comparable sensitivity and improved spatial resolution near the center of the hemisphere, compared to the helmet-chin PET scanner.

Imaging Crustal Structure with Waveform and HV Ratio of Body-wave Receiver Function

NASA Astrophysics Data System (ADS)

Chong, J.; Chu, R.; Ni, S.; Meng, Q.; Guo, A.

2017-12-01

It is known that receiver function has less constraint on the absolute velocity, and joint inversion of receiver function and surface wave dispersion has been widely applied to reduce the non-uniqueness of velocity and interface depth. However, some studies indicate that the receiver function itself is capable for determining the absolute shear wave velocity. In this study, we propose to measure the receiver function HV ratio which takes advantage of the amplitude information of the radial and vertical receiver functions to constrain the shear-wave velocity. Numerical analysis indicates that the receiver function HV ratio is sensitive to the average shear wave velocity in the depth range it samples, and can help to reduce the non-uniqueness of receiver function waveform inversion. A joint inversion scheme has been developed, and both synthetic tests and real data application proved the feasibility of the joint inversion. The method has been applied to the dense seismic array of ChinArray program in SE Tibet during the time period from August 2011 to August 2012 in SE Tibet (ChinArray-Himalaya, 2011). The measurements of receiver function HV ratio reveals the lateral variation of the tectonics in of the study region. And main features of the velocity structure imagined by the new joint inversion method are consistent with previous studies.

Objective We determined the utility of electrocorticography (ECoG) and stimulation for detecting language-related sites in patients with left-hemispheric language-dominance on Wada test. Methods We studied 13 epileptic patients who underwent language mapping using event-related gamma-oscillations on ECoG and stimulation via subdural electrodes. Sites showing significant gamma-augmentation during an auditory-naming task were defined as language-related ECoG sites. Sites at which stimulation resulted in auditory perceptual changes, failure to verbalize a correct answer, or sensorimotor symptoms involving the mouth were defined as language-related stimulation sites. We determined how frequently these methods revealed language-related sites in the superior-temporal, inferior-frontal, dorsolateral-premotor, and inferior-Rolandic regions. Results Language-related sites in the superior-temporal and inferior-frontal gyri were detected by ECoG more frequently than stimulation (p < 0.05), while those in the dorsolateral-premotor and inferior-Rolandic regions were detected by both methods equally. Stimulation of language-related ECoG sites, compared to the others, more frequently elicited language symptoms (p < 0.00001). One patient developed dysphasia requiring in-patient speech therapy following resection of the dorsolateral-premotor and inferior-Rolandic regions containing language-related ECoG sites not otherwise detected by stimulation. Conclusions Language-related gamma-oscillations may serve as an alternative biomarker of underlying language function in patients with left-hemispheric language-dominance. Significance Measurement of language-related gamma-oscillations is warranted in presurgical evaluation of epileptic patients. PMID:22503906

Growing evidence emphasizes a positive role of brain ipsilesional (IL) reorganization in stroke patients with partial recovery. Ten patients affected by a monohemispheric stroke in the middle cerebral artery territory underwent functional magnetic resonance (fMRI) and magnetoencephalography (MEG) evaluation of the primary sensory (S1) activation via the same paradigm (median nerve galvanic stimulation). Four patients did not present S1 fMRI activation [Rossini, P.M., Altamura, C., Ferretti, A., Vernieri, F., Zappasodi, F., Caulo, M., Pizzella, V., Del Gratta, C., Romani, G.L., Tecchio, F., 2004. Does cerebrovascular disease affect the coupling between neuronal activity and local haemodynamics? Brain 127, 99-110], although inclusion criteria required bilateral identifiable MEG responses. Mean Euclidean distance between fMRI and MEG S1 activation Talairach coordinates was 10.1+/-2.9 mm, with a 3D intra-class correlation (ICC) coefficient of 0.986. Interhemispheric asymmetries, evaluated by an MEG procedure independent of Talairach transformation, were outside or at the boundaries of reference ranges in 6 patients. In 3 of them, the IL activation presented medial or lateral shift with respect to the omega-shaped post-rolandic area while in the other 3, IL areas were outside the peri-rolandic region. In conclusion, despite dissociated intensity, the MEG and fMRI activations displayed good spatial consistency in stroke patients, thus confirming excessive interhemispheric asymmetries as a suitable indicator of unusual recruitments in the ipsilesional hemisphere, within or outside the peri-rolandic region.

The Low Energy Beam and Ion Trap (LEBIT) Penning trap mass spectrometer was used to perform an improved-precision mass measurement of 72Br and the low-lying isomeric state, Brm72, giving mass excesses of -59 062.2 (1.0 )keV and -58 960.9 (1.2 )keV , respectively. These values are consistent with the values from the 2012 atomic mass evaluation [Chin. Phys. C 36, 1603 (2012), 10.1088/1674-1137/36/12/003] and the Nubase2012 evaluation of nuclear properties [Chin. Phys. C 36, 1157 (2012), 10.1088/1674-1137/36/12/001]. The uncertainties on the mass of the ground state and isomeric state have been reduced by a factor of seven.

Epidermal electronics for electromyography: An application to swallowing therapy.

Head and neck cancer treatment alters the anatomy and physiology of patients. Resulting swallowing difficulties can lead to serious health concerns. Surface electromyography (sEMG) is used as an adjuvant to swallowing therapy exercises. sEMG signal collected from the area under the chin provides visual biofeedback from muscle contractions and is used to help patients perform exercises correctly. However, conventional sEMG adhesive pads are relatively thick and difficult to effectively adhere to a patient's altered chin anatomy, potentially leading to poor signal acquisition in this population. Here, the emerging technology of epidermal electronics is introduced, where ultra-thin geometry allows for close contouring of the chin. The two objectives of this study were to (1) assess the potential of epidermal electronics technology for use with swallowing therapy and (2) assess the significance of the reference electrode placement. This study showed comparative signals between the new epidermal sEMG patch and the conventional adhesive patches used by clinicians. Furthermore, an integrated reference yielded optimal signal for clinical use; this configuration was more robust to head movements than when an external reference was used. Improvements for future iterations of epidermal sEMG patches specific to day-to-day clinical use are suggested. Copyright © 2016 IPEM. Published by Elsevier Ltd. All rights reserved.

Plastic surgeons often approach nasal aesthetic evaluation with the aid of seemingly objective measurements. However, ideal measurements of an attractive nose, as suggested in the literature, might not apply on a cross-cultural basis. Given these controversies, this study aimed to investigate the cultural and ethnic impact on nasal shape preferences. Computerized images of a model's nose were generated in which the nasal width, root, tip, dorsum, and projection of the lips and chin could be altered. A survey containing these images was sent to over 13,000 plastic surgeons and lay people in 50 different countries, with a total response rate of 9.6 percent. Demographic information about the interviewees was obtained. Preferred dimensions of the nose were broken down according to geographic, ethnic, occupational, and sex variables. Interregional comparison revealed that plastic surgeons from Latin America and the Caribbean overall prefer smaller and narrower noses, with more projecting tips, lips, and chins. Similar trends hold true when analyzing results from the general public. Significant differences were found comparing preferences between plastic surgeons and the general public. Plastic surgeons preferred wider nasal roots and tips and, in combination, more projected nasal dorsi, tips, lips, and chins. No universal parameter can define ideal aesthetics of the nose across cultures and ethnic backgrounds. As demonstrated, geographic, ethnic, and cultural factors influence aesthetic perceptions of patients and surgeons.

On 100 individuals (men = women), aged 18 to 30 years with normal faces and occlusions, 34 linear and 7 angular measurements as well as 24 indices were calculated. The difference of measurements between men and women were evaluated by paired t-test. The data were compared with the norms of North American whites using 1-sample t-test. The subjects belonged to 5 ethnic groups (57% from Fars, 14% from Kord, 11% from Azari, 10% from Gilaki-Mazani, and 2% from Lor). All head measurements were greater in men except for the head index and the head height. The subjects had leptoprosopic faces. The intercanthal width was almost one third of the biocular width and greater than the eye fissure length. Although the nose width of women was significantly smaller, both sexes had leptorrhine noses. The chin height and lower chin height were greater in men. In comparison with North American whites, considerable differences were found regarding head height and width, biocular width, nose height, face height, mouth width, and upper chin height. In conclusion, the reference range of craniofacial anthropometric measurements established for the Iranian population might be efficiently used for esthetic treatments.

Metal and selenium concentrations in blood and feathers of petrels of the genus Procellaria.

PubMed

Carvalho, Paloma Calábria; Bugoni, Leandro; McGill, Rona A R; Bianchini, Adalto

2013-07-01

Concentrations of copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb), mercury (Hg), and selenium (Se) were determined in blood and feathers of spectacled (Procellaria conspicillata) and white-chinned (Procellaria aequinoctialis) petrels, species that are phylogenetically related, but with distinct ecological niches. In winter, they feed on similar foods, indicated by an overlapping range of whole-blood stable isotopes values (δ(15) N; δ(13) C). No relation was found between blood metal concentration and stable isotope values. In spectacled petrels, metal concentrations appeared lower in blood (Cu = 0.79-20.77 µg/g; Zn = 10.95-28.02 µg/g; Cd = 1.73-10.11 µg/g; Pb = 5.02-26.03 µg/g; Hg = 0.84-9.86 µg/g) than in feathers (Cu = 1.05-21.57 µg/g; Zn = 45.30-81.49 µg/g; Cd = 3.76-10.44 µg/g; Pb = 16.53-59.00 µg/g; Hg = 4.24-24.03 µg/g). In white-chinned petrels, metal concentrations also appeared lower in blood (Cu = 0.62-10.4 µg/g; Zn = 10.73-24.69 µg/g; Cd = 2.00-6.31 µg/g; Pb = 5.72-24.03 µg/g) than in feathers (Cu = 2.68-23.92 µg/g; Zn = 48.96-93.54 µg/g; Cd = 5.72-24.03 µg/g; Pb = 18.62-55.51 µg/g), except for Hg (blood = 0.20-15.82 µg/g; feathers = 0.19-8.91 µg/g). Selenium (0.24-14.18 µg/g) and Hg (0.22-1.44 µg/g) concentrations showed a positive correlation in growing feathers of spectacled petrels. Blood and feather Hg levels were higher in spectacled petrels while feathers Cu and Zn concentrations were greater in white-chinned petrels. Juvenile white-chinned petrels exhibited greater blood Hg concentrations than adults. In the south Atlantic Ocean, discards from commercial fishing operations consumed by spectacled petrels year-round and by white-chinned petrels during the wintering period have elevated Hg concentrations. Because Hg toxicity is associated with behavioral and reproductive changes in birds, it could

A helmet formed of a rigid shell is disclosed. The shell is lined with several air filled bladders to contact firmly the head of a user. The shell has a rigid chin bar supporting a bite bar connected fixedly to a mouthpiece bearing against the teeth and hard palate to firmly anchor the helmet without movement. The outer shell surface supports various air pumping bulbs and accelerometers. Separate left and right visor pivot on the side guided in a central tongue and groove track to move optical lens mounts into the user's field of vision. The chin bar is connected to the shell by a pair of releasable clasps. A safety lanyard connects to the clasps to quickly pull pins from the clasps to enable quick release in case of motion sickness.

Local ICA for the Most Wanted face recognition

Facial disguises of FBI Most Wanted criminals are inevitable and anticipated in our design of automatic/aided target recognition (ATR) imaging systems. For example, man's facial hairs may hide his mouth and chin but not necessarily the nose and eyes. Sunglasses will cover the eyes but not the nose, mouth, and chins. This fact motivates us to build sets of the independent component analyses bases separately for each facial region of the entire alleged criminal group. Then, given an alleged criminal face, collective votes are obtained from all facial regions in terms of 'yes, no, abstain' and are tallied for a potential alarm. Moreover, and innocent outside shall fall below the alarm threshold and is allowed to pass the checkpoint. Such a PD versus FAR called ROC curve is obtained.

Experimental studies of cosmic rays at the highest energies (above 1018 eV) are the main scientific goal of the projected large area network of extensive air shower detectors. 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 plan to construct the large area network of extensive air shower detectors placed on the roofs of high school buildings in the city of Łódź. 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.

Endoscopic subcondylar fracture repair: functional, aesthetic, and radiographic outcomes.

PubMed

Lee, C; Mueller, R V; Lee, K; Mathes, S J

1998-10-01

An endoscopic method of mandibular subcondylar fracture repair has been described recently. To determine the effectiveness of this new technique, we longitudinally studied functional, aesthetic, and radiographic parameters following endoscopic repair of 22 subcondylar fractures in 20 patients. Restoration of mandibular function was achieved without postoperative maxillomandibular fixation. Premorbid occlusion was restored. Clinical jaw motion was found to progressively increase with a mean interincisal jaw opening of 43 mm achieved after the eighth postoperative week. Patients were pleased with the aesthetic restoration of their chin projection,jaw line, and the symmetric midline movement of the chin point onjaw opening. Anatomic fracture reduction with rigid plate fixation was confirmed on early postsurgical radiographs. Late radiographs showed fracture union without remodeling of the condylar head. Endoscopic subcondylar fracture repair was efficacious at functional, aesthetic, and radiographic restoration of the mandible.

Columbia Basin Research uses the COMPASS model on a daily basis during the outmigration of Snake River Chinook and steelhead smolts to predict downstream passage and survival. Fish arrival predictions and observations from program RealTime along with predicted and observed environmental conditions are used to make in-season predictions of arrival and survival to various dams in the Columbia and Snake Rivers. For 2008, calibrations of travel and survival parameters for two stocks of fish-Snake River yearling PIT-tagged wild chinook salmon (chin1pit) and Snake River PIT-tagged steelhead (lgrStlhd)-were used to model travel and survival of steelhead and chinook stocks from Lowermore » Granite Dam (LWG) or McNary Dam (MCN) to Bonneville Dam (BON). This report summarizes the success of the COMPASS/RealTime process to model these migrations as they occur. We compared model results on timing and survival to data from two sources: stock specific counts at dams and end-of-season control survival estimates (Jim Faulkner, NOAA, pers. comm. Dec. 16, 2008). The difference between the predicted and observed day of median passage and the Mean Absolute Deviation (MAD) between predicted and observed arrival cumulative distributions are measures of timing accuracy. MAD is essentially the average percentage error over the season. The difference between the predicted and observed survivals is a measure of survival accuracy. Model results and timing data were in good agreement from LWG to John Day Dam (JDA). Predictions of median passage days for the chin1pit and lgrStlhd stocks were 0 and 2 days (respectively) later than observed. MAD for chin1pit and lgrStlhd stocks at JDA were 2.3% and 5.9% (respectively). Between JDA and BON modeling and timing data were not as well matched. At BON, median passage predictions were 6 and 10 days later than observed and MAD values were 7.8% and 16.0% respectively. Model results and survival data were in good agreement from LWG to MCN.

Detecting insomnia in patients with low back pain: accuracy of four self-report sleep measures

PubMed Central

2013-01-01

Background Although insomnia is common in patients with low back pain (LBP), it is unknown whether commonly used self-report sleep measures are sufficiently accurate to screen for insomnia in the LBP population. This study investigated the discriminatory properties of the Pittsburgh Sleep Quality Index (Pittsburgh questionnaire), Insomnia Severity Index (Insomnia index), Epworth Sleepiness Scale (Epworth scale) and the sleep item of the Roland and Morris Disability Questionnaire (Roland item) to detect insomnia in patients with LBP by comparing their accuracy to detect insomnia to a sleep diary. The study also aimed to determine the clinical optimal cut-off scores of the questionnaires to detect insomnia in the LBP population. Methods Seventy nine patients with LBP completed the four self-reported questionnaires and a sleep diary for 7 consecutive nights. The accuracy of the questionnaires was evaluated using Receiver Operator Characteristic (ROC) curves with the Area Under the Curve (AUC) used to examine each test’s accuracy to discriminate participants with insomnia from those without insomnia. Results The Pittsburgh questionnaire and Insomnia index had moderate accuracy to detect insomnia (AUC = 0.79, 95% CI = 0.68 to 0.87 and AUC = 0.78, 95% CI = 0.67 to 0.86 respectively), whereas the Epworth scale and the Roland item were not found to be accurate discriminators (AUC = 0.53, 95% CI = 0. 41 to 0.64 and AUC = 0.64, 95% CI = 0.53 to 0.75 respectively). The cut-off score of > 6 for the Pittsburgh questionnaire and the cut-off point of > 14 for the Insomnia index provided optimal sensitivity and specificity for the detection of insomnia. Conclusions The Pittsburgh questionnaire and Insomnia index had similar ability to screen for insomnia in patients with low back pain. PMID:23805978

To determine the effectiveness of lessons in the Alexander technique, massage therapy, and advice from a doctor to take exercise (exercise prescription) along with nurse delivered behavioural counselling for patients with chronic or recurrent back pain. Factorial randomised trial. 64 general practices in England. 579 patients with chronic or recurrent low back pain; 144 were randomised to normal care, 147 to massage, 144 to six Alexander technique lessons, and 144 to 24 Alexander technique lessons; half of each of these groups were randomised to exercise prescription. Normal care (control), six sessions of massage, six or 24 lessons on the Alexander technique, and prescription for exercise from a doctor with nurse delivered behavioural counselling. Roland Morris disability score (number of activities impaired by pain) and number of days in pain. Exercise and lessons in the Alexander technique, but not massage, remained effective at one year (compared with control Roland disability score 8.1: massage -0.58, 95% confidence interval -1.94 to 0.77, six lessons -1.40, -2.77 to -0.03, 24 lessons -3.4, -4.76 to -2.03, and exercise -1.29, -2.25 to -0.34). Exercise after six lessons achieved 72% of the effect of 24 lessons alone (Roland disability score -2.98 and -4.14, respectively). Number of days with back pain in the past four weeks was lower after lessons (compared with control median 21 days: 24 lessons -18, six lessons -10, massage -7) and quality of life improved significantly. No significant harms were reported. One to one lessons in the Alexander technique from registered teachers have long term benefits for patients with chronic back pain. Six lessons followed by exercise prescription were nearly as effective as 24 lessons. National Research Register N0028108728.

Validation of a self-report questionnaire. The purpose of this study was to investigate adaptation, validity, and reliability of the Turkish version of the Bournemouth Questionnaire. Low back pain is one of the most frequent disorders leading to activity limitation. This pain affects most of people in their lives. The most important point to evaluate patient's functional abilities and to decide a successful therapy procedure is to manage the assessment questionnaires precisely. One hundred ten patients with chronic low back pain were included in present study. To assess reliability, test-retest and internal consistency analyses were applied. The results of test-retest analysis were assessed by using Intraclass Correlation Coefficient method (95% confidence interval). For internal consistency, Cronbach alpha value was calculated. Validity of the questionnaire was assessed in terms of construct validity. For construct validity, factor analysis and convergent validity were tested. For convergent validity, total points of the Bournemouth Questionnaire were assessed with the total points of Quebec Back Pain Disability Scale and Roland Morris Disability Questionnaire by using Pearson correlation coefficient analysis. Cronbach alpha value was found 0.914, showing that this questionnaire has high internal consistency. The results of test-retest analysis were varying between 0.851 and 0.927, which shows that test-retest results are highly correlated. Factor analysis test indicated that this questionnaire had one factor. Pearson correlation coefficient of the Bournemouth Questionnaire with Roland Morris Disability Questionnaire was calculated 0.703 and it was found with Quebec Back Pain Disability Scale is 0.659. These results showed that the Bournemouth Questionnaire is very good correlated with Roland Morris Disability Questionnaire and Quebec Back Pain Disability Scale. The Turkish version of the Bournemouth Questionnaire is valid and reliable. 3.

Quantum adiabatic algorithm is a method of solving computational problems by evolving the ground state of a slowly varying Hamiltonian. The technique uses evolution of the ground state of a slowly varying Hamiltonian to reach the required output state. In some cases, such as the adiabatic versions of Grover's search algorithm and Deutsch-Jozsa algorithm, applying the global adiabatic evolution yields a complexity similar to their classical algorithms. However, using the local adiabatic evolution, the algorithms given by J. Roland and N.J. Cerf for Grover's search [J. Roland, N.J. Cerf, Quantum search by local adiabatic evolution, Phys. Rev. A 65 (2002) 042308] and by Saurya Das, Randy Kobes, and Gabor Kunstatter for the Deutsch-Jozsa algorithm [S. Das, R. Kobes, G. Kunstatter, Adiabatic quantum computation and Deutsh's algorithm, Phys. Rev. A 65 (2002) 062301], yield a complexity of order N (where N=2(n) and n is the number of qubits). In this paper, we report the experimental implementation of these local adiabatic evolution algorithms on a 2-qubit quantum information processor, by Nuclear Magnetic Resonance.

Twelve nations would join efforts to initiate a vast research programme aimed to penetrate the mysteries of the white continent. Three Frenchmen, Jacques Dubois, a meteorologist, Roland Schlich, a geophysicist, and Claude Lorius a glaciologist, occupied the Charcot Station built near the South magnetic pole and located 320 km from the coast, during a whole year without any possibility of relief. They wintered from January 1957 to January 1958 in an aluminium hut only 24 m2 in size, buried under the ice. Today, Roland Schlich of the School and Observatory of Earth Sciences, Strasbourg and Claude Lorius of the Laboratory of Glaciology and Geophysics of the Environment, Grenoble, are the last witnesses of this wintering and they remember … The film traces this human and scientific adventure, thanks to their evidence and unpublished documents, filmed 50 years ago.

Chin, Alvin; Chignell, Mark; Wang, Hao

2010-04-01

As a first step in the development of community trackers for large-scale online interaction, this paper shows how cohesive subgroup analysis using the Social Cohesion Analysis of Networks (SCAN; Chin and Chignell 2008) and Data-Intensive Socially Similar Evolving Community Tracker (DISSECT; Chin and Chignell 2010) methods can be applied to the problem of identifying cohesive subgroups and tracking them over time. Three case studies are reported, and the findings are used to evaluate how well the SCAN and DISSECT methods work for different types of data. In the largest of the case studies, variations in temporal cohesiveness are identified across a set of subgroups extracted from the inferred social network. Further modifications to the DISSECT methodology are suggested based on the results obtained. The paper concludes with recommendations concerning further research that would be beneficial in addressing the community tracking problem for online data.

Motor imagery beyond the motor repertoire: Activity in the primary visual cortex during kinesthetic motor imagery of difficult whole body movements.

PubMed

Mizuguchi, N; Nakata, H; Kanosue, K

2016-02-19

To elucidate the neural substrate associated with capabilities for kinesthetic motor imagery of difficult whole-body movements, we measured brain activity during a trial involving both kinesthetic motor imagery and action observation as well as during a trial with action observation alone. Brain activity was assessed with functional magnetic resonance imaging (fMRI). Nineteen participants imagined three types of whole-body movements with the horizontal bar: the giant swing, kip, and chin-up during action observation. No participant had previously tried to perform the giant swing. The vividness of kinesthetic motor imagery as assessed by questionnaire was highest for the chin-up, less for the kip and lowest for the giant swing. Activity in the primary visual cortex (V1) during kinesthetic motor imagery with action observation minus that during action observation alone was significantly greater in the giant swing condition than in the chin-up condition within participants. Across participants, V1 activity of kinesthetic motor imagery of the kip during action observation minus that during action observation alone was negatively correlated with vividness of the kip imagery. These results suggest that activity in V1 is dependent upon the capability of kinesthetic motor imagery for difficult whole-body movements. Since V1 activity is likely related to the creation of a visual image, we speculate that visual motor imagery is recruited unintentionally for the less vivid kinesthetic motor imagery of difficult whole-body movements.

Full-face motorcycle helmet protection from facial impacts: an investigation using THOR dummy impacts and SIMon finite element head model.

PubMed

Whyte, Thomas; Gibson, Tom; Eager, David; Milthorpe, Bruce

2017-06-01

Facial impacts are both common and injurious for helmeted motorcyclists who crash; however, there is no facial impact requirement in major motorcycle helmet standards. This study examined the effect of full-face motorcycle helmet protection on brain injury risk in facial impacts using a test device with biofidelic head and neck motion. A preliminary investigation of energy absorbing foam in the helmet chin bar was carried out. Flat-faced rigid pendulum impacts were performed on a THOR dummy in an unprotected (no helmet) and protected mode (two full-face helmet conditions). The head responses of the dummy were input into the simulated injury monitor finite element head model to analyse the risk of brain injury in these impacts. Full-face helmet protection provides a significant reduction in brain injury risk in facial impacts at increasing impact speeds compared with an unprotected rider (p<0.05). The effect of low-density crushable foam added to the chin bar could not be distinguished from an unpadded chin bar impact. Despite the lack of an impact attenuation requirement for the face, full-face helmets do provide a reduction in head injury risk to the wearer in facial impacts. The specific helmet design factors that influence head injury risk in facial impacts need further investigation if improved protection for helmeted motorcyclists is to be achieved.

Fermented foods have positive health effects in adults and children if consumed regularly. However, lack of knowledge and perceptions to-wards fermented foods may limit their usage. This study aimed to assess the caregivers' awareness and usage of fermented foods for feeding children in peri-urban/rural communities of Gauteng Province. A qualitative exploratory study was conducted in June, 2012, in a peri-urban/rural community to assess the awareness and use of fermented foods by child caregivers attending a local antenatal clinic through focus group discussions. Thirty three caregivers participated in the study; however 29 indicated their demographic profiles. Four major themes that emerged from the analysis included knowledge on fermented foods, perceived benefits of fermentation, varied views about fermentation and feeding practices. Fermented foods that caregivers, their families and community members consume include ting, fat cakes, dumplings, sorghum beer and mageu. Findings also showed that children consumed fermented foods in form of soft ting porridge; and yoghurt, marketed as Activia and Danone commercial brands. Also, caregivers were not comfortable feeding their children with fermented foods, indicating their limited knowledge on the nutri-tional value of these foods. It is critical to promote caregivers' knowledge and use of fermented foods for feeding infants and young children in South African rural communities.

Nobel laureate Professor Samuel C. C. Ting of the Massachusetts Institute of Technology pauses for a photo in the Space Station Processing Facility. Dr. Ting is directing an experiment, an international collaboration of some 37 universities and laboratories, using a state-of-the-art particle physics detector called the Alpha Magnetic Spectrometer (AMS), which will fly on a future launch to the International Space Station. Using the unique environment of space, the AMS will study the properties and origin of cosmic particles and nuclei including antimatter and dark matter. AMS flew initially as a Space Shuttle payload on the June 1998 mission STS-91 that provided the investigating team with data on background sources and verified the detector’s performance under actual space flight conditions. The detector’s second space flight is scheduled to be launched on mission UF-4 October 2003 for installation on the Space Station as an attached payload. Current plans call for operating the detector for three years before it is returned to Earth on the Shuttle. Using the Space Station offers the science team the opportunity to conduct the long-duration research above the Earth’s atmosphere necessary to collect sufficient data required to accomplish the science objectives

Reverse engineering the whole-genome networks of complex multicellular organisms continues to remain a challenge. While simpler models easily scale to large number of genes and gene expression datasets, more accurate models are compute intensive limiting their scale of applicability. To enable fast and accurate reconstruction of large networks, we developed Tool for Inferring Network of Genes (TINGe), a parallel mutual information (MI)-based program. The novel features of our approach include: (i) B-spline-based formulation for linear-time computation of MI, (ii) a novel algorithm for direct permutation testing and (iii) development of parallel algorithms to reduce run-time and facilitate construction of large networks. We assess the quality of our method by comparison with ARACNe (Algorithm for the Reconstruction of Accurate Cellular Networks) and GeneNet and demonstrate its unique capability by reverse engineering the whole-genome network of Arabidopsis thaliana from 3137 Affymetrix ATH1 GeneChips in just 9 min on a 1024-core cluster. We further report on the development of a new software Gene Network Analyzer (GeNA) for extracting context-specific subnetworks from a given set of seed genes. Using TINGe and GeNA, we performed analysis of 241 Arabidopsis AraCyc 8.0 pathways, and the results are made available through the web. PMID:23042249

We studied the histology and morphometrics of the hairs of bowhead whales (Balaena mysticetus). These whales are hairless except for two patches of more than 300 hairs on the rostral tip of the lower lip and chin, the rostral tip of the upper lip, and a bilateral row of approximately ten hairs caudal to the blowhole. Histological data indicate that hairs in all three of these areas are vibrissae: they show an outermost connective tissue capsule, a circumferential blood sinus system surrounding the hair shaft, and dense innervation to the follicle. Morphometric data were collected on hair diameters, epidermal recess diameters, hair follicle length, and external hair lengths. The main difference between the hairs in the different regions is that blowhole hairs have larger diameters than the hairs in the chin and rostrum regions. We speculate that the hair shaft thickness patterns in bowheads reflect functional specializations. © 2015 Wiley Periodicals, Inc.

Managing the Cutaneous Sinus Tract of Dental Origine.

PubMed

Janev, Edvard; Redzep, Enis

2016-09-15

Draining cutaneous sinus tract in chin area may be caused by chronic periapical dental infections. Misdiagnosis of these lesions usually leads to destructive invasive treatment of the sinus tract that is not correct and curative. A 31-year-old male patient referred to us with a chronically draining lesion on his chin. The lesion previously was misdiagnosed by medical doctors and had undergone two times surgery with a focus on the skin lesion and had received antibiotic therapy for a prolonged period of time. After clinical and radiologic examination the dental origin of the lesion was evident and proper endodontic and surgical treatment was performed. Three months later, after the treatment, the lesion showed total healing and reoccurrence occurred. The key to successful treatment of cutaneous sinus tract of dental origin must be in appropriate communication between the dentist and the physician in order to achieve correct diagnosis and therapy in such cases.

Facial beauty depends on shape, proportion, and harmony between the facial thirds. The chin is one of the most important components of the inferior third and has an important role on the definition of facial aesthetic and harmony in both frontal and lateral views. There are 2 principal therapeutic approaches that one can choose to treat mental deformities, alloplastic implants, and mental basilar ostectomy, also known as genioplasty. The latest is more commonly used because of great versatility in the correction of three-dimensional deformities of the chin and smaller taxes of postoperative complications. Possible transoperative and postoperative complications of genioplasty include mental nerve lesion, bleeding, damage to tooth roots, bone resorption of the mobilized segment, mandibular fracture, ptosis of the lower lip, and failure to stabilize the ostectomized segment. The study presents 2 cases of displacement of the osteotomized segment after genioplasty associated with facial trauma during postoperative orthognathic surgery followed by rare complications with no reports in the literature.

The efficacy of rehabilitative exercises for chronic dysphagia treatment in head and neck cancer survivors has not been studied extensively and is ambiguous. A prospective clinical phase II study using an intensive strength training program was carried out in 17 head and neck cancer survivors with chronic dysphagia. Both swallow and nonswallow exercises were performed for 6-8 weeks with a newly developed tool allowing for progressive muscle overload, including chin tuck, jaw opening, and effortful swallow exercises. Outcome parameters were feasibility, compliance, and parameters for effect. Feasibility in terms of the program completion rate was 88%. Compliance with the exercises was 97%. After the training period, chin tuck, jaw opening, and anterior tongue strength had substantially improved. All but 1 patient reported to benefit from the exercises. Feasibility and compliance were high. Some objective and subjective effects of progressive load on muscle strength and swallowing function could be demonstrated. © 2017 Wiley Periodicals, Inc.

2014-03-01

This study aimed to compare facial morphologies of an adult African-American population to an adult Caucasian-American population using three-dimensional (3D) surface imaging. The images were captured using a stereophotogrammetric system (3dMDface(TM) system). Subjects were aged 19-30 years, with normal body mass index and no gross craniofacial anomalies. Images were aligned and combined using RF6 Plus Pack 2 software to produce a male and female facial average for each population. The averages were superimposed and the differences were assessed. The most distinct differences were in the forehead, alar base and perioricular regions. The average difference between African-American and Caucasian-American females was 1·18±0·98 mm. The African-American females had a broader face, wider alar base and more protrusive lips. The Caucasian-American females had a more prominent chin, malar region and lower forehead. The average difference between African-American and Caucasian-American males was 1·11±1·04 mm. The African-American males had a more prominent upper forehead and periocular region, wider alar base and more protrusive lips. No notable difference occurred between chin points of the two male populations. Average faces were created from 3D photographs, and the facial morphological differences between populations and genders were compared. African-American males had a more prominent upper forehead and periocular region, wider alar base and more protrusive lips. Caucasian-American males showed a more prominent nasal tip and malar area. African-American females had broader face, wider alar base and more protrusive lips. Caucasian-American females showed a more prominent chin point, malar region and lower forehead.

Cephalometric outcomes of orthognathic surgery in hemifacial microsomia.

PubMed

2014-09-01

Hemifacial microsomia is a hypoplastic disorder of the first and second branchial arches that significantly impacts on the development of the jaws, leading to malocclusion and facial asymmetry. There is little in the literature regarding the application of orthodontic/orthognathic approaches to the correction of these deformities and the stability of the surgical results. To address this, a retrospective chart review of 10 patients with complete orthodontic records and greater than 1 year of follow-up was performed. Posteroanterior cephalograms were assessed by modified Grummons analysis to determine mandibular offset (deviation of the chin point from the skeletal midline) and occlusal cant. These measurements were performed at 3 time points (T1: preoperative, T2: immediate postoperative, T3: follow-up) to elucidate the surgical movement (T2-T1), the postoperative relapse (T3-T2), and the net gain movement (T3-T1). Maxillary movements were quantified, and the occlusal cant was expressed as a ratio between vertical heights of the maxilla at the first molar on each side. One sample t test demonstrated statistically significant surgical movement and net gain. Relapse was statistically insignificant. Repeated-measures analysis of variance demonstrated similar results for chin point position relative to the putative midline. Our results suggest that a combined orthodontic/orthognathic approach at skeletal maturity delivers improved occlusal outcomes in the long term as assessed by chin point deviation and occlusal cant, but secondary surgery rates are higher than those for orthognathic surgery in other patient groups. We advocate limiting surgery to skeletal maturity whenever possible to achieve stable long-term results while limiting morbidity and number of procedures.

A computer program implements parallel- processing algorithms for cor relating images of terrain acquired by stereoscopic pairs of digital stereo cameras on an exploratory robotic vehicle (e.g., a Mars rove r). Such correlations are used to create three-dimensional computatio nal models of the terrain for navigation. In this program, the scene viewed by the cameras is segmented into subimages. Each subimage is assigned to one of a number of central processing units (CPUs) opera ting simultaneously.

It has been argued recently that Australian historians have overlooked histories of emotion. In this article, through the life-history analysis of two long-standing Sydney gay activists, I trace the emotional currents of radical gay activism and suggest these histories point to a wider story of Left melancholy in the closing decades of the twentieth century. I argue that their melancholia is not a trauma-like despair but surprisingly is tinged with a sustaining hope.

Alpha-Band Brain Oscillations Shape the Processing of Perceptible as well as Imperceptible Somatosensory Stimuli during Selective Attention.

PubMed

Forschack, Norman; Nierhaus, Till; Müller, Matthias M; Villringer, Arno

2017-07-19

Attention filters and weights sensory information according to behavioral demands. Stimulus-related neural responses are increased for the attended stimulus. Does alpha-band activity mediate this effect and is it restricted to conscious sensory events (suprathreshold), or does it also extend to unconscious stimuli (subthreshold)? To address these questions, we recorded EEG in healthy male and female volunteers undergoing subthreshold and suprathreshold somatosensory electrical stimulation to the left or right index finger. The task was to detect stimulation at the randomly alternated cued index finger. Under attention, amplitudes of somatosensory evoked potentials increased 50-60 ms after stimulation (P1) for both suprathreshold and subthreshold events. Prestimulus amplitude of peri-Rolandic alpha, that is mu, showed an inverse relationship to P1 amplitude during attention compared to when the finger was unattended. Interestingly, intermediate and high amplitudes of mu rhythm were associated with the highest P1 amplitudes during attention and smallest P1 during lack of attention, that is, these levels of alpha rhythm seemed to optimally support the behavioral goal ("detect" stimuli at the cued finger while ignoring the other finger). Our results show that attention enhances neural processing for both suprathreshold and subthreshold stimuli and they highlight a rather complex interaction between attention, Rolandic alpha activity, and their effects on stimulus processing. SIGNIFICANCE STATEMENT Attention is crucial in prioritizing processing of relevant perceptible (suprathreshold) stimuli: it filters and weights sensory input. The present study investigates the controversially discussed question whether this attention effect extends to imperceptible (subthreshold) stimuli as well. We found noninvasive EEG signatures for attentional modulation of neural events following perceptible and imperceptible somatosensory stimulation in human participants. Specifically

Gain in Body Fat Is Associated with Increased Striatal Response to Palatable Food Cues, whereas Body Fat Stability Is Associated with Decreased Striatal Response

PubMed Central

Yokum, Sonja

2016-01-01

Cross-sectional brain-imaging studies reveal that obese versus lean humans show greater responsivity of reward and attention regions to palatable food cues, but lower responsivity of reward regions to palatable food receipt. However, these individual differences in responsivity may result from a period of overeating. We conducted a repeated-measures fMRI study to test whether healthy weight adolescent humans who gained body fat over a 2 or 3 year follow-up period show an increase in responsivity of reward and attention regions to a cue signaling impending milkshake receipt and a simultaneous decrease in responsivity of reward regions to milkshake receipt versus adolescents who showed stability of or loss of body fat. Adolescents who gained body fat, who largely remained in a healthy weight range, showed increases in activation in the putamen, mid-insula, Rolandic operculum, and precuneus to a cue signaling impending milkshake receipt versus those who showed stability of or loss of body fat, though these effects were partially driven by reductions in responsivity among the latter groups. Adolescents who gained body fat reported significantly greater milkshake wanting and milkshake pleasantness ratings at follow-up compared to those who lost body fat. Adolescents who gained body fat did not show a reduction in responsivity of reward regions to milkshake receipt or changes in responsivity to receipt and anticipated receipt of monetary reward. Data suggest that initiating a prolonged period of overeating may increase striatal responsivity to food cues, and that maintaining a balance between caloric intake and expenditure may reduce striatal, insular, and Rolandic operculum responsivity. SIGNIFICANCE STATEMENT This novel, repeated-measures brain-imaging study suggests that adolescents who gained body fat over our follow-up period experienced an increase in striatal responsivity to cues for palatable foods compared to those who showed stability of or loss of body fat

Caregivers’ Knowledge and Use of Fermented Foods for Infant and Young Children Feeding in a Rural Community of Odi, Gauteng Province, South Africa

Background: Fermented foods have positive health effects in adults and children if consumed regularly. However, lack of knowledge and perceptions to­wards fermented foods may limit their usage. This study aimed to assess the caregivers’ awareness and usage of fermented foods for feeding children in peri-urban/rural communities of Gauteng Province. Methods: A qualitative exploratory study was conducted in June, 2012, in a peri-urban/rural community to assess the awareness and use of fermented foods by child caregivers attending a local antenatal clinic through focus group discussions. Results: Thirty three caregivers participated in the study; however 29 indicated their demographic profiles. Four major themes that emerged from the analysis included knowledge on fermented foods, perceived benefits of fermentation, varied views about fermentation and feeding practices. Fermented foods that caregivers, their families and community members consume include ting, fat cakes, dumplings, sorghum beer and mageu. Findings also showed that children consumed fermented foods in form of soft ting porridge; and yoghurt, marketed as Activia and Danone commercial brands. Also, caregivers were not comfortable feeding their children with fermented foods, indicating their limited knowledge on the nutri­tional value of these foods. Conclusion: It is critical to promote caregivers’ knowledge and use of fermented foods for feeding infants and young children in South African rural communities. PMID:25097837

Facial asymmetry is very common in maxillofacial deformities. It is difficult to achieve accurate reconstruction. With the help of 3D printing models and surgical templates, the osteotomy line and the amount of bone grinding can be accurate. Also, by means of the precise repositioning instrument, the repositioning of genioplasty can be accurate and quick. In this study, we present a three-dimensional printing technique and the precise repositioning instrument to guide the osteotomy and repositioning, and illustrate their feasibility and validity. Eight patients with complex facial asymmetries were studied. A precise 3D printing model was obtained. We made the preoperative design and surgical templates according to it. The surgical templates and precise repositioning instrument were used to obtain an accurate osteotomy and repositioning during the operation. Postoperative measurements were made based on computed tomographic data, including chin point deviation as well as the symmetry of the mandible evaluated by 3D curve functions. All patients obtained satisfactory esthetic results, and no recurrences occurred during follow-up. The results showed that we achieved clinically acceptable precision for the mandible and chin. The mean and SD of ICC between R-Post and L-Post were 0.973 ± 0.007. The mean and SD of chin point deviation 6 months after the operation were 0.63 ± 0.19 mm. The results of this study suggest that the three-dimensional printing technique and the precise repositioning instrument could aid in making better operation designs and more accurate manipulation in orthognathic surgery for complex facial asymmetry.

Glia initiate brain assembly through non-canonical Chimaerin/Furin axon guidance in C. elegans

PubMed Central

Rapti, Georgia; Li, Chang; Shan, Alan; Lu, Yun; Shaham, Shai

2017-01-01

Brain assembly is hypothesized to begin when pioneer axons extend over non-neuronal cells, forming tracts guiding follower axons. Yet pioneer-neuron identities, their guidance substrates, and their interactions, are not well understood. Here, using time-lapse embryonic imaging, genetics, protein-interaction, and functional studies, we uncover the early events of C. elegans brain assembly. We demonstrate that C. elegans glia are key for assembly initiation, guiding pioneer and follower axons using distinct signals. Pioneer sublateral neurons, with unique growth properties, anatomy, and innervation, cooperate with glia to mediate follower-axon guidance. We further identify a CHIN-1/Chimaerin-KPC-1/Furin double mutant that severely disrupts assembly. CHIN-1/Chimaerin and KPC-1/Furin function non-canonically in glia and pioneer neurons for guidance-cue trafficking. We exploit this bottleneck to define roles for glial Netrin and Semaphorin in pioneer- and follower-axon guidance, respectively, and for glial and pioneer-neuron Flamingo/CELSR in follower-axon navigation. Altogether, our studies reveal previously-unknown glial roles in pioneer-axon guidance, suggesting conserved brain-assembly principles. PMID:28846083

Optical phonetics and visual perception of lexical and phrasal stress in English.

In a study of optical cues to the visual perception of stress, three American English talkers spoke words that differed in lexical stress and sentences that differed in phrasal stress, while video and movements of the face were recorded. The production of stressed and unstressed syllables from these utterances was analyzed along many measures of facial movement, which were generally larger and faster in the stressed condition. In a visual perception experiment, 16 perceivers identified the location of stress in forced-choice judgments of video clips of these utterances (without audio). Phrasal stress was better perceived than lexical stress. The relation of the visual intelligibility of the prosody of these utterances to the optical characteristics of their production was analyzed to determine which cues are associated with successful visual perception. While most optical measures were correlated with perception performance, chin measures, especially Chin Opening Displacement, contributed the most to correct perception independently of the other measures. Thus, our results indicate that the information for visual stress perception is mainly associated with mouth opening movements.

Facial packs or masks are popular beauty treatments that are thought to improve skin quality. We formulated a yoghurt pack using natural ingredients (F-YOP), with consideration of skin affinity, safety, health, and beauty. Then, we performed an in vitro assessment of biological activity and in vivo assessments of moisture, TEWL, melanin content, and elasticity. Facial areas treated with F-YOP showed increased moisture compared to control regions: 89±6.26% (forehead), 140.72±10.19% (cheek), and 123.29±6.67% (chin). Transepidermal water loss (TEWL) values were decreased in the treated areas compared to control: 101.38±6.95% (forehead), 50.37±5.93% (cheek), and l57.81±10.88% (chin). Elasticity was decreased in the control region, whereas the treatment region did not change. The initial elasticity was maintained in the cheek. F-YOP exhibited activity on DPPH radical scavenging, SOD-like activity, and lipoxygenase activity. F-YOP treatment successfully improved the moisture, brightness, and elasticity of treated skin.

Innovative procedure for computer-assisted genioplasty: three-dimensional cephalometry, rapid-prototyping model and surgical splint.

PubMed

Olszewski, R; Tranduy, K; Reychler, H

2010-07-01

The authors present a new procedure of computer-assisted genioplasty. They determined the anterior, posterior and inferior limits of the chin in relation to the skull and face with the newly developed and validated three-dimensional cephalometric planar analysis (ACRO 3D). Virtual planning of the osteotomy lines was carried out with Mimics (Materialize) software. The authors built a three-dimensional rapid-prototyping multi-position model of the chin area from a medical low-dose CT scan. The transfer of virtual information to the operating room consisted of two elements. First, the titanium plates on the 3D RP model were pre-bent. Second, a surgical guide for the transfer of the osteotomy lines and the positions of the screws to the operating room was manufactured. The authors present the first case of the use of this model on a patient. The postoperative results are promising, and the technique is fast and easy-to-use. More patients are needed for a definitive clinical validation of this procedure. Copyright 2010 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Duplications of the terminal long arm of chromosome 20 are rare chromosomal anomalies. We report a male infant found on array comparative genomic hybridization analysis to have a 19.5 Mb duplication of chromosome 20q13.12-13.33, as well as an 886 kb deletion of 20p13 at 18,580-904,299 bp. This anomaly occurred as the recombinant product of a paternal pericentric inversion. There have been 23 reported clinical cases involving 20qter duplications; however, to our knowledge this is only the second reported patient with a paternal pericentric inversion resulting in 46,XY,rec(20)dup(20q). This patient shares many characteristics with previously described patients with 20qter duplications, including microphthalmia, anteverted nares, long ears, cleft palate, small chin, dimpled chin, cardiac malformations, and normal intrauterine growth. While there is variable morbidity in patients with terminal duplications of 20q, a review of previously reported patients and comparison to our patient's findings shows significant phenotypic similarity. © 2014 Wiley Periodicals, Inc.

Hazard detection and avoidance sensor for NASA's planetary landers

NASA Technical Reports Server (NTRS)

Lau, Brian; Chao, Tien-Hsin

1992-01-01

An optical terrain analysis based sensor system specifically designed for landing hazard detection as required for NASA's autonomous planetary landers is introduced. This optical hazard detection and avoidance (HDA) sensor utilizes an optoelectronic wedge-and-ting (WRD) filter for Fourier transformed feature extraction and an electronic neural network processor for pattern classification. A fully implemented optical HDA sensor would assure safe landing of the planetary landers. Computer simulation results of a successful feasibility study is reported. Future research for hardware system implementation is also provided.

Symphysis pubis pain is a significant problem for some pregnant women. The purpose of this study was to investigate the effects of exercise, advice, and pelvic support belts on the management of symphysis pubis dysfunction during pregnancy. Ninety pregnant women with symphysis pubis dysfunction were randomly assigned to 3 treatment groups. A randomized masked prospective experimental clinical trial was conducted. Specific muscle strengthening exercises and advice concerning appropriate methods for performing activities of daily living were given to the 3 groups, and 2 of the groups were given either a rigid pelvic support belt or a nonrigid pelvic support belt. The dependent variables, which were measured before and after the intervention, were a Roland-Morris Questionnaire score, a Patient-Specific Functional Scale score, and a pain score (101-point numerical rating score). After the intervention, there was a significant reduction in the Roland-Morris Questionnaire score, the Patient-Specific Functional Scale score, and the average and worst pain scores in all groups. With the exception of average pain, there were no significant differences between groups for the other measures. The findings indicate that the use of either a rigid or a nonrigid pelvic support belt did not add to the effects provided by exercise and advice.

Monitoring of wind load and response for cable-supported bridges in Hong Kong

NASA Astrophysics Data System (ADS)

Wong, Kai-yuen; Chan, Wai-Yee K.; Man, King-Leung

2001-08-01

Structural health monitoring for the three cable-supported bridges located in the West of Hong Kong or the Tsing Ma Control Area has been carried out since the opening of these bridges to public traffic. The three cable-supported bridges are referred to as the Tsing Ma (suspension) Bridge, the Kap Shui Mun (cable-stayed) Bridge and the Ting Kau (cable-stayed) Bridge. The structural health monitoring works involved are classified as six monitoring categories, namely, wind load and response, temperature load and response, traffic load and response, geometrical configuration monitoring, strains and stresses/forces monitoring and global dynamic characteristics monitoring. As wind loads and responses had been a major concern in the design and construction stages, this paper therefore outlines the work of wind load and response monitoring on Tsing Ma, Kap Shui Mun and Ting Kau Bridges. The paper starts with a brief description of the sensory systems. The description includes the layout and performance requirements of sensory systems for wind load and responses monitoring. Typical results of wind load and response monitoring in graphical forms are then presented. These graphical forms include the plots of wind rose diagrams, wind incidences vs wind speeds, wind turbulence intensities, wind power spectra, gust wind factors, coefficient of terrain roughness, extreme wind analyses, deck deflections/rotations vs wind speeds, acceleration spectra, acceleration/displacement contours, and stress demand ratios. Finally conclusions on wind load and response monitoring on the three cable-supported bridges are drawn.

A preliminary validation of a new measure of occupational health and safety.

PubMed

Cadieux, Jean; Roy, Mario; Desmarais, Lise

2006-01-01

This article describes the validation of an instrument designed to conduct an Occupational Health and Safety (OHS) self-diagnosis using workers observations of tangible facts and actions in the workplace. The instrument puts the emphasis on observable factors that make it possible to act proactively before accidents actually occur. Three companies were recruited from the printing sector in Québec based on their OHS performance (low, medium, and high), their interest in the project, and their availability. The master sample was composed of 269 people. Partial least squares (PLS) and vanishing tetrad analyses were used to study the behavior of the formative scales developed. The results indicate that partial revision of the instrument will be necessary to reach a fully satisfying level of validity. With regards to the statistical approach adopted, the use of a macro called CTA-SAS 2.0 developed by Bollen and Ting [Bollen, K.A., & Ting, K.-F. (1993). Confirmatory tetrad analysis. In P.V. Marsden (Ed.), Social methodology.Vol.23 (pp.147-176). Cambridge, MA: Blackwell, 23] has proven to be effective in providing a suitable statistical treatment of the latent formative variables on which our instrument's development is based. The results suggest that the instrument appears to be relatively robust and appropriate to diagnose OHS leading measures. In the long run, this instrument will make it possible for companies to draw a more refined picture of OHS evolution, even in the absence of occupational injuries.

Feeling Bad and Looking Worse: Negative Affect Is Associated with Reduced Perceptions of Face-Healthiness

2014-01-01

Some people perceive themselves to look more, or less attractive than they are in reality. We investigated the role of emotions in enhancement and derogation effects; specifically, whether the propensity to experience positive and negative emotions affects how healthy we perceive our own face to look and how we judge ourselves against others. A psychophysical method was used to measure healthiness of self-image and social comparisons of healthiness. Participants who self-reported high positive (N = 20) or negative affectivity (N = 20) judged themselves against healthy (red-tinged) and unhealthy looking (green-tinged) versions of their own and stranger’s faces. An adaptive staircase procedure was used to measure perceptual thresholds. Participants high in positive affectivity were un-biased in their face health judgement. Participants high in negative affectivity on the other hand, judged themselves as equivalent to less healthy looking versions of their own face and a stranger’s face. Affective traits modulated self-image and social comparisons of healthiness. Face health judgement was also related to physical symptom perception and self-esteem; high physical symptom reports were associated a less healthy self-image and high self-reported (but not implicit) self-esteem was associated with more favourable social comparisons of healthiness. Subject to further validation, our novel face health judgement task could have utility as a perceptual measure of well-being. We are currently investigating whether face health judgement is sensitive to laboratory manipulations of mood. PMID:25259802
