    Allergic contact dermatitis is a significant clinical problem in children and one that the use of essential oils and natural remedies probably exacerbates. We report a case of chronic plaque psoriasis replaced by allergic contact dermatitis in a 12-year-old boy. We suspect that the immunologic response to a hapten in lavender oil disrupted the pathogenesis of psoriasis, causing the psoriasis to temporarily "disappear." PMID:26646574

    A 12-year-old congenitally-blind girl drew a car moving, stationary, and braking. For stationary, she put the wheels inside the car and, for braking, drew the wheels as rough rectangles. At the age verbal metaphor is understood (Winner, 1988), the girl invented metaphoric drawings. In these, what is shown is not what is meant. In late childhood, metaphor may be understood similarly in pictures and words and by the sighted and blind.

    Full Text Available ABSTRACT To determine the level of oral hygiene, periodontal status and treatment needs in 12 years old students in Castro City, Los Lagos region, during March and April of 2014, indicating if there are differences between men and women. A cross-sectional study was carried out. 242 12 years old students from Castro´s municipal and subsidized private schools were selected through a stratified random sample from each school. Students were evaluated by a calibrated examiner, to determine the Simplified Oral Hygiene Index (OHI-S and the Community Periodontal Index of Treatment Needs (CPITN. Data were transferred to a Microsoft Excel spreadsheet and statistically analyzed to calculate amount and percentage of the variables, the Mann-Whitney U test was used for comparison between gender. 59.5% of the students have a regular hygiene. Also, 86.4% of the adolescents have gingivitis and 13.6% of them have periodontitis. The periodontal treatment needs indicates that 58% of the students requires oral hygiene instructions and scaling. No statistically significant differences were found between gender. There is a higher prevalence of periodontal diseases in Castro than the regional and national reference in 12 years old adolescents associated with a regular oral hygiene. It is necessary to teach and promote specific public health strategies based on epidemiological data.

    Undifferentiated sarcomas are rare tumors not classified into any sarcoma subtype. Due to their rarity, imaging findings of undifferentiated sarcomas are poorly characterized. The purpose of this report was to present imaging findings of a pathologically confirmed undifferentiated sarcoma originated from the left kidney of a 12-year-old boy. The mass was infiltrative involving the renal pelvis. It mimicked massive hilar lymphadenopathy with a preserved renal contour visible by both ultrasonography and CT. Renal vein thrombosis was also observed. Although undifferentiated sarcomas are rare, they should be considered in differential diagnosis of infiltrative renal masses with renal pelvis invasion in children.

    Full Text Available Background and Aim: Extensive studies on the epidemiology of teeth and oral diseases are an important part of health care programs specially for hearing impaired groups. For adequate programming in this field, proper situation analysis is mandatory. The aim of this study was to assess the DMFT (decayed missed filled teeth of 12 years old students attending hearing impaired schools in Tehran and exploring the relation between sex, hygiene and hearing threshold with the index. Materials and Methods: This cross sectional descriptive study was based on examining 12 years old (± 6 month students (117 cases attending hearing impaired schools in Tehran. A questionnaire was filled for each case. T, Chi-square and Kruskall-Wallis tests were used to analyze the results with p<0.05 as the limit of significance. Results: The mean DMFT in these students was 3.07. Mean DMFT in students with very severe hearing loss was 2.99. Mean ranked DMFT in girls and boys was similar (56.09 in boys and 61.96 in girls. Mean ranked DMFT in students who didn’t use floss (66.40 was higher than those who used floss (46.71. Mean ranked DMFT in students who seldom brushed, was the highest (72.82 and in students who brushed once a day was the lowest (51.26. Conclusion: The DMFT index in hearing disabled children was 3.07. Regular brushing and flossing reduced the index.

    Full Text Available The last two decades a huge progress has taken place in the field of the primary prevention of infections and many new vaccines have been introduced in the compulsory vaccination program. There is evidence, however, that immunization coverage against some infectious diseases is not adequate. Aim: It was to investigate the level of immunization coverage of Greek and Immigrants' children aged 4-12 years old in the prefecture of Evritania regarding vaccines against pertussis-diphtheria-tetanus (DTaP, poliomyelitis (IPV and measles–mumps–rubella (MMR. Material and methods: The sample of the study consisted of the pupils of all nursing and elementary schools of the prefecture of Evritania , aged 4-12 years old. Children's personal Health Cards were used to evaluate the adequacy of vaccine doses. X2 was usedfor comparisons. Statistics was processed with SPPS 17.0. Results: The boys of the sample were 469 (51.9% and the girls 434 (48.1%. Full vaccination coverage with DTaP, MMR and IPV was 87.3%, 79.9%, and 97.6% respectively. No statistically significant differences were observed between Greek and Immigrants' children. Conclusion: Vaccination coverage against measles, mumps and rubella was inadequate. Immigrants' and Greek children are equally covered. Vaccination coverage with MMR is troublesome.

    The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6- to 12-year-old children in a physical education setting. Four hundred sixty-three Dutch children (211 girls, 252 boys) completed three tests: the Körperkoordinationstest für Kinder (KTK) and two Athletic Skills Tracks (AST-1, AST-2). The validity of AST-1 and AST-2 was examined by correlating the time (s) needed to complete the tracks and the KTK Motor Quotient (MQ). Overall, there was a low correlation between AST-1 and the KTK MQ (r = -0.474 (P year-olds. The results indicate that fundamental movement skills of 6- to 12-year-old children can be assessed with a quick, convenient and low-cost motor competence test in a physical education setting, i.e., an Athletic Skills Track. Future studies should further assess the reliability, discriminative ability and validity of age-specific versions of the AST.

    We sought to determine the prevalence of interictal epileptiform discharges (IEDs) in healthy 11- and 12-year-old children. Sixth grade students with no history of seizure, or neurologic or psychiatric disease, were enrolled in a longitudinal physical activity intervention study. Per study protocol, each student had two EEG recordings approximately 6months apart. Epileptiform discharges were present in 4 (2.9%) of 140 students: centrotemporal in three and generalized in one. In three children, the discharges were still present six months later. None of the children had developed seizures a minimum of one year after the second EEG. These results are consistent with those of two landmark European studies performed nearly a half century ago, before the modern era of digital EEG. Healthy 11- and 12-year-old children with no history of seizure may have centrotemporal or generalized epileptiform discharges on EEG, which can persist for at least 6months. Based on both our results and those of the two prior European studies, such discharges, if found incidentally in otherwise healthy children in this age group, should not prompt further evaluation or treatment.

    Full Text Available Background and Objectives: The group of 6-12 year-old students are the main target of oral health programs due to the high prevalence of dental caries and the formation of permanent teeth during this age and the lifestyle-shaping nature of the period. Schools provide the easiest and most effective means of accessing this group. The present study was conducted to examine the impact of school-based interventions on improved oral health in 6-12 year-old students. Materials and Methods: The present systematic review searched for its English and Persian keywords in databases such as the Scopus, Proquest, Science Direct, Pubmed, Springer, Biomed Central, Google Scholar, IranMedex and SID and examined studies published between January 2004 and September 2014 about educational interventions aiming to prevent oral diseases and promote associated health behaviors in students. Results: The 17 studies selected for examination were divided into two categories: first, assessing an education based on self-care behaviors and preventive services second, assessing an education based on self-care behaviors only. Those interventions that were consistent in nature, involved the parents and the school personnel, used behavior change models, used a combination of several training methods, used practical experiences and provided preventive services were more effective in promoting knowledge and health behaviors and reducing dental caries and plaque in this group of children. Conclusion: Providing consistent community-based education, using a combination of several organized educational programs, following up on the children's progress, using behavior change theories and models and providing prevention services are the most effective measures for achieving the desired goals.

    Full Text Available "nThe aim of the present study was to determine the effects of adenotonsillectomy on height, weight and body mass index (BMI in children under 12 years old, with or without airway obstruction and evaluation of the risk of overweight in them. In this case-control study, 120 children with the age of 2-12 years old were studied; 60 children as case group who underwent adenotonsillectomy and 60 healthy children as control group. After collecting the data related to appetite status and sleep breathing disorder of the case group, height, weight and BMI have been measured for all children in two stages; preoperatively and 6 months later. Also in the case group, BMI percentiles, pre and postoperatively have been calculated. Patients with Low appetite in the initiation and at the end of the study in the case group were 80% and 8.3% respectively (P=0.01. Mean of height, weight and BMI variation after 6 months were significantly different between case and control groups (P<0.05. BMI percentiles in the case group preoperatively were: 20% underweight, 67% healthy weight, 10% at risk of over weight, 3% over weight. Postoperatively, after 6 months BMI percentiles in order of above frequency were: 10%, 57%, 22% and 11% (P=0.02. Analysis of the results showed that adenotonsillectomy can lead to increase of height, weight, BMI and appetite not only in the children with low weight due to airway obstruction but also in the normal weight and over weight children. Therefore risk of overweight should be mentioned as a probable undesirable outcome of adenotonsillectomy.

    Full Text Available The aim of this study was to describe malocclusion prevalence and its association with individual and contextual factors among Brazilian 12-year-old schoolchildren. This cross-sectional study included data from an oral health survey carried out in Goiânia, Brazil (n = 2,075, and data from the files of the local health authority. The data were collected through oral clinical examinations. The Dental Aesthetic Index (DAI was used to assess occlusion. The presence of malocclusion (DAI > 25 was used as the dependent variable. The individual independent variables consisted of adolescents’ sex and race and their mothers’ level of schooling. The clinical variables were caries experience and presence of adverse periodontal condition (calculus and/or gingival bleeding. The contextual variables included type of school and the location of schools in the city’s health districts. The Rao-Scott test and multilevel logistic regression were performed. The prevalence of malocclusion was 40.1%. In the final model, significantly higher rates of malocclusion were found among those who attended schools located in less affluent health districts and whose mothers had fewer years of education. Rates were also higher among those presenting calculus and/or gingival bleeding. Malocclusion demonstrated a high prevalence rate and the inequalities in its distribution were determined by individual and contextual factors.

    Full Text Available Idiopathic central serous chorioretinopathy (CSC typically affects middle-aged males. To date, only one case of idiopathic CSC in a prepubertal subject has been reported. Atypical idiopathic CSC presentation may be challenging to diagnose. Exclusion of secondary causes of serous retinal detachment (SRD is warranted. We describe the atypical case of a 12-year-old female with a circumscribed SRD that resolved spontaneously and with fluorescein angiography (FA findings that were compatible with idiopathic CSC. Optical coherence tomography (OCT and systemic assessment were performed to exclude other etiologies. FA demonstrated multiple focal leaks in early phases, with subretinal leakage and pooling in late phases. OCT showed a localized circumscribed retinal detachment. Complete blood count was within normal limits. Serum cortisol was normal (22.1 µg/dl and mean arterial blood pressure was 100/60 mm Hg, thereby excluding secondary causes of CSC. This is the second reported case of idiopathic CSC in a prepubertal female and the first one documented by FA and OCT, as well as other studies to exclude secondary causes. Albeit rare, idiopathic CSC should be considered in the differential diagnosis of SRD in this (prepubertal age group, after excluding secondary ocular or systemic etiologies.

  6. Scrotal and retroperitoneal lymphangioma of a 12-year-old boy: case report

    International Nuclear Information System (INIS)

    Lymphangiomas occurs in children quite frequently. They are most commonly localized in the head, neck, axilla, chest, abdomen, and retroperitoneum. Lymphangiomas of the scrotum are very rare and are usually clinically silent, so they are a challenge for radiologists performing US examination in children. They are obliged to differentiate the following lesions: torsion of the testicle, scrotal hernia, hydrocoele, and epididymal cyst, in addition to the masses of primary extra-testicular localization such as hemagioma, congenital vascular malformations, fibromas, and malignant tumors. Additional difficulties appear in boys who present acute scrotum syndrome. The paper reports the diagnostics and treatment of a huge multicystic lymphangioma situated in he scrotum and retroperitoneum of a 12-year-old boy who had fallen from a bicycle and presented acute scrotum. The lesion of the scrotum was surgically excised. Retroperitoneal lymphangioma was detected during this operation. Subsequent diagnostics was based on ultrasonography, computerized tomography, and magnetic resonance imaging of the abdominal cavity. The lymphangioma of the retroperitoneum was resected. The patient shows no evidence of recurrence after 7 years. Cystic lymphangiomas are rare but benign intra-scrotal, extra-testicular, painless masses in children. They are sonographically multicystic or multiloculated abnormalities and may show infiltrative extension to the perineum, retroperitoneum, or abdomen. Recognition of this entity and its extent is important for correct clinical management and may be for planning treatment. (author)

    Lyme arthritis (LA) may be confused with other rheumatic diseases, particularly in the absence of a history of erythema migrans (EM). We report the case of a 12-year-old patient who developed a large effusion of the right knee joint. The titer for antinuclear antibodies was 1:80 and the test for rheumatoid factor was negative. Investigations for antibody response to Borrelia burgdorferi demonstrated remarkable elevation of IgG antibody and no specific IgM response. These results were confirmed by immunoblotting reactivity with the bands p83/100, p58, p43, p41, p39, OspA, p30, OspC, p21, and p17. We subsequently learned that the child had suffered a tick bite followed by an EM 5 years earlier and had been treated with trimethoprim/sulfamethoxazole at that time. The patient now was given intravenous ceftriaxone, 2 g daily for 14 days. In the absence of clinical improvement 3 weeks later a knee joint aspiration was performed which resulted in a positive polymerase chain reaction (PCR) test for B. burgdorferi DNA (OspA) in the synovial fluid. The patient fully recovered 2 months later without further treatment. The case indicates that the latency period between EM and onset of LA may last up to 5 years. In addition to serologic test methods, analysis of synovial fluid using PCR may be decisive for making the final diagnosis of LA.

Treatment ways need a lot of time, but they have little success, so it is important to prevent caries. Now if we want to have a successful model, having person's statistics is important and useful for our Research purposes. This research was done to detect caries free prevalence in students twelve year of age in Izeh city and it contained 2groups of girls and boys. It was done to indicate the connection between caries free prevalence and individual oral hygiene with brushing times, numbers during 24 hours. Methods: This research is a kind of epidemiological and descriptive study. It was done in Izeh city in 78-79 educational years. Its only document, was selection the 12 years old students. Informations collected by clinical inspections and interrogatory J method Sample volume was 400 students according to this formula N=Z2(1-p/ d2. We use Chi-square statistics test and also its soft disk (SPSS or statitistics program was about social science. Conclusion: Caries free prevalence within the whole sample was 16.5%and it was 17.5% within the girls and 15-5% within boys. According to brushing times numbers, 25% brushed once a day, 47% brushed twice and 5.5% brushed three time a day and 22.5% never brushed their teeth. Discussin and conclusion: According to the obtained dates, caries prevalence related to sex difference was meaningless and they had no connection with each other there was a meaningful connection between brushing times, numbers and oral hygiene situation which caries free developed by increasing anyone of them.

    According to a recent study it could be shown that more than one third of female high school students and more than 20 % of male students in the age of 14 to 18 years indicated an impaired eating behaviour, expressed as a medium or high risk to develop eating disorders based upon the standardized Eating Attitudes Test (EAT) . The current study tested the prevalence of weight concerns and dieting as an indicator of problematic eating behaviour among younger children. 230 Thuringian female and male students in the 3 (rd) and 4 (th) year (between 8 and 12-years-old) as well as their parents were investigated using standardized and modified instruments. Weight and height were measured directly to determine the Body Mass Index (BMI) that was put into relation to some factors of potential influence such as parents, peers, media and eating behaviours. It could be shown that 42 % of the boys and 53 % of the girls preferred a thin ideal body image; 32 % of the children revealing normal weight expressed the wish to be thinner. 18 % of the boys and 19 % of the girls tried to lose weight at the time of the investigation. Dieting was influenced by the perceived (not actual) dieting behaviour of the parents. The BMI significantly predicted weight concerns: In total, 85 % of the overweight children but also 17 % of the children with normal weight were convinced to be overweight. The girls' eating behaviour was mostly influenced by the peers, the boys' behaviour by criticism of the parents. Generally, a significant influence of the media could be demonstrated. PMID:15986283

    Full Text Available Background The causes of obesity in children are multifactorial, including genetics, physiology, metabolism, psychology, socioeconomic status, lifestyle, and culture. Objective To assess for relationships between obesity in 6 to 12-year-old children and maternal nutritional status, maternal education, eating breakfast, eating fast food, physical activity, TV watching, and playing video games. Methods This case-control study included students of Sejahtera Public School aged 6 to 12 years. Questionnaires were distributed to their parents for data on maternal education, eating breakfast, eating fast food, physical activity, TV watching and playing video games. Maternal nutritional status was assessed by one of the researchers. Univariate analysis with Chi–square test was used to assess every risk factor. Those with a P value of <0.25 were subjected to multivariate analysis, performed using multiple logistic regression analysis. Results From June to July 2013, 60 obese children and 60 well-nourished children, as a control group, were enrolled in the study. Obese mothers tended to have obese children [odds ratio/OR 252.48; 95%CI 33.4 to 1908.4]. Children who ate fast food 6–8 times/week, had low physical activity, and watched TV more than 8 hours/week had significantly higher risk for obesity [OR 12.94, 95%CI 1.7 to 100.7; and OR 266.94, 95% CI 7.8 to 9137.7; OR 21.44, 95%CI 2.68 to 171.61; respectively]. Maternal education, eating breakfast, and playing video games were not significant risk factors for childhood obesity. Conclusion Maternal obesity, eating fast food 6-8 times per week, low physical activity and watching TV more than 8 hours/week are risk factors for childhood obesity.

Objectives: To determine the prevalence of malocclusion in children aged 10-12 years in Kozhikode district of Kerala, South India. Materials and methods: A descriptive cross-sectional study was conducted among schoolchildren aged 10-12 years in six schools in Kozhikode district of Kerala, South India. A total of 2,366 children satisfied the inclusion criteria. Occlusal characteristics like crossbite, open bite, deep bite, protrusion of teeth, midline deviations, midline diastema and tooth rotation were recorded. The data were tabulated and analyzed using Chi-square test. Results: The results revealed that the overall prevalence of malocclusion was 83.3%. Of this, 69.8% of the children had Angle’s class I malocclusion, 9.3% had class II malocclusion (division 1 = 8.85%, division 2 = 0.5%) and 4.1% had class III malocclusion; 23.2% showed an increased overjet (>3 mm), 0.4% reverse overjet, 35.6% increased overbite (>3 mm), 0.29% open bite, 7.2% crossbite with 4.6% crossbite of complete anterior teeth, 63.3% deviation of midline, 0.76% midline diastema and 3.25% rotated tooth. No significant differences in gender distributions of malocclusions were noted except for increased overjet and overbite. Conclusion: There is high prevalence of malocclusion among schoolchildren in Kozhikode district of Kerala. Early interception and early correction of these malocclusions will eliminate the potential irregularities and malpositions in the developing dentofacial complex.

    Oral Submucous Fibrosis (OSMF) is a chronic debilitating, potentially malignant disorder of the oral cavity. It is characterized by restricted mouth opening which results due to abnormal accumulation of collagen in the sub-epithelial layers leading to dense fibrous bands in the mouth. The pathogenesis of the disease is believed to be multifactorial. However, literature reports suggest a strong association of OSMF and arecanut chewing habit. The present paper presents a case of OSMF in a 12-year-old boy without arecanut chewing habit, but with a heavy practice of chewing tamarind seeds.

    Stroke is a well-known complication of sickle cell disease (SCD). It is estimated to occur in approximately 11% of patients with SCD by the age of 20. The most frequent cause of cerebrovascular accident (CVA) is blockage of the intracranial internal carotid and middle cerebral arteries. Hemorrhagic stroke is less common, occurring in approximately 3% of children by age 20. Transcranial Doppler (TCD) is the standard test for prediction of stroke risk in children with sickle cell anemia. The authors present a case of a 12-year-old female with SCD transferred to their institution after suffering a catastrophic intracranial hemorrhage. Her most recent TCD was normal 6 months prior to her admission.

    Exercise-induced asthma is seen following vigorous or prolonged exercise or physical exertion. It has been suggested that climatic conditions have an influence on exercise-induced asthma. Therefore, the aim of the present study was to examine the effect of two climatic conditions on exercise-induced deterioration of pulmonary function tests in 10-12 year old students. Two hundred and fifty six students were randomly chosen from two cities namely Kerman and Gorgan (128 subjects in each who were equally from both cities) including 62 girls and 66 boys of 10-12 years old. A questionnaire was used to obtain demographic information and to identify the prevalence of asthma symptoms. Each subject performed a seven-minute free run exercise with maximum effort and sufficient motivation until they reached 70-75% heart rate. Pulmonary function tests (PFT) including, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), and maximum expiratory flow at 50% of vital capacity (MEF50) were measured before, at the beginning, and 7 and 20 min after physical activity. The prevalence of both asthma (28.12%) and exercise-induced asthma (20.31%) in Kerman students was higher than those of Gorgan students (21.09% and 17%, respectively). All PFT values declined 7 and 20 min post-exercise in both groups. Although all baselines PFT in Kerman students were higher than those of Gorgan students, the decline in PFT values in Kerman students was greater than those of Gorgan students. At 20 min post exercise, the decline in FEV1, PEF and MEF50 in Kerman students was significantly higher than those of Gorgan students (p exercise-induced asthma in a city with dry and cool climate such as Kerman was higher than in a city with humid climate such as Gorgan. In addition, the results showed that in a humid climate, post-exercise decline in PFT values was less than in a dry climate. PMID:27634077

    Full Text Available Background and Aims: Oral health is an essential component of health throughout life. Hardly any information is available on the oral health status of children in Gurgaon. Thus, the present study was conducted among 5-year-old and 12-years-old children in schools in rural Gurgaon. Materials and Methods: A total of 1003 children were examined of which 619 were in 5 years age group and 384 in 12 years group. The prevalence of dental caries was studied using dentition status and treatment needs index. For dental calculus criteria of Community Periodontal and for dental fluorosis Dean′s index was used. Results: In 5 years age group prevalence of dental caries was 68.5%, dental fluorosis was 22.5% and treatment needs were 63.7%. In 12 year age group prevalence of dental caries was 37.5%, dental fluorosis was 76.04%, highest community periodontal index score was 2, seen in 80.2% and overall treatment needs were 44.3%. Conclusion: Preventive approaches seem to be a viable alternative to tackle the overwhelming problem of dental caries and other oral diseases. Provision of oral health education in schools and school based preventive programs are important for improvement of this situation.

    Full Text Available The study aimed to describe periodontal health status and its association with individual and contextual factors among 12-year-old schoolchildren in a midwest Brazilian capital city. This cross-sectional study included data from an oral health survey carried out in 2010 in the city of Goiania, Brazil and secondary data obtained from the local health authority. Data were collected through oral clinical examinations and interviews. For assessment of periodontal status two components of the community periodontal index (CPI were used: calculus and bleeding after probing. Dependent variable was presence of any periodontal condition. Independent individual variables were the children’s sex and color/race, and their mother’s level of schooling. Contextual variables were related to the schools (type and existence of toothbrushing program and its geographic location in the health districts. Rao-Scott test and multilevel Poisson analysis were performed. The prevalence of calculus and/or bleeding was 7%. Brown color, public schools, and those located in health district with intermediate socioeconomic indicators were associated to a higher prevalence of this condition. The prevalence of adverse periodontal condition was low and the inequalities in its distribution were determined by individual as well as contextual factors related to the schools and the geographic area.

    Full Text Available Objective: We have undertaken a cross-sectional study to assess factors associated with dental pain that determine the expressed needs for dental care among 12-year-old school children in India. Materials and Methods: A total of 2 250 school children were surveyed after being drawn through stratified cluster random sampling. The simultaneous effects of sociodemographic characteristics, pain characteristics, and the impact of pain on the quality of life were studied in association with the expressed needs for dental treatment. Results: Among the studied school children, 71.4% suffered from dental pain, only 27.7% expressed need for dental healthcare. Socioeconomic status (SES was a statistically significant determinant. Pain characteristics like the severity of pain and pain on eating hot and cold foods were significantly associated with expressed needs. Impact characteristics associated with expressed needs were embarrassment in showing teeth, brushing teeth, and difficulty in eating and drinking. Logistic regression analysis yielded a Nagelkerke R 2 value of 0.106. Conclusion: Important determinants of expressed needs for dental care among the studied population were SES, pain intensity, pain on thermal stimuli, impact characteristics like eating/drinking and embarrassment in showing teeth.

    Background Evidence from animal and human studies suggests that early-life stress such as physical maltreatment has long-lasting effects on the hypothalamic-pituitary-adrenal (HPA) axis and is associated with blunted HPA axis reactivity in adulthood. Few studies have investigated whether blunted HPA axis reactivity observed in children exposed to early-life stress signals social, emotional, and behavioral problems. Methods Participants were 190 12-year-old children (50.5% males) recruited from the Environmental Risk Longitudinal Twin Study, a nationally representative 1994 to 1995 cohort of families with twins. Cortisol responses to psychosocial stress were measured in maltreated/ bullied (n = 64) and comparison children (n = 126). We ascertained maltreatment and bullying victimization using mothers’ reports and assessed children’s social, emotional, and behavioral problems at ages 5 and 12 using mothers’ and teachers’ reports. Results Piecewise multilevel growth curve analyses indicated that maltreated/bullied and comparison children showed distinct cortisol responses to stress. Specifically, maltreated/bullied children had lower cortisol responses than comparison children who exhibited a significant increase. Lower cortisol responses were, in turn, associated with more social and behavioral problems among maltreated/bullied children. Conclusions These findings provide support for the influence of childhood harm on blunted HPAaxis reactivity and its potential impacton children’s functioning. Our findings emphasize the need to integrate stress biomarkers in guiding prevention efforts for young victims. PMID:21839988

    2012-01-01

    Full Text Available The nutcracker syndrome (NCS is a rare cause of haematuria. It embraces an extended nonpathognomonic spectrum of symptoms that imply a difficult diagnosis. Ultimately it may be associated with substantial morbidity and even life-threatening events. We report a rare cause if a 12-year-old boy who presented with a history of frequent intermittent episodes of painless constant haematuria. The cystoscopy showed a bloody urine ejaculate from the left ureter meatus. The Doppler ultrasonography showed turbulent pattern of venous blood flow of the posterior renal vein branch behind the aorta. The abdominopelvic computer tomography (apCT revealed left renal vein (LRV duplication with a dilated retroaortic branch, entrapped between the aorta and the vertebral column, promoting the renal nutcracker syndrome. The patient was initially hospitalized and managed with oral iron supplements and continuous saline bladder irrigation, not requiring additional treatment. The child is currently asymptomatic, with haemoglobin value returning to normal and therefore proposed to conservative management with close followup. The authors present a case report of episodic haematuria caused by a rare entity—posterior nutcracker syndrome with renal vein duplication.

Independent variables were measured through a questionnaire, and dependent variables were determined through oral examination. Multiple and logistic regression were applied. Results: The decayed, missing and filled permanent teeth/decayed, filled primary teeth (DMFT-dft value in the sample was 1.83 (95% confidence interval [CI], 1.67-1.98, the DMFT value was 1.53 (95% CI, 1.37-1.67, and the prevalence of caries was 61% (95% CI, 57.7-64.5. The prevalence of caries was directly related to a low frequency of brushing, greater use of toothpaste, and a higher consumption of sweets. The prevalence of caries was higher in rural than in urban areas. In contrast, the higher the mother's level of education and the greater the subject's knowledge of dental health, the lower the prevalence of caries.

    Background. Physical activity is important for children's physical, mental, and social well-being. Outdoor active play is an important yet unstudied domain of children's physical activity. The objective of this study was to determine if parental encouragement is associated with the frequency that children engage in outdoor active play outside of school hours. Methods. Participants consisted of 514 children aged 7-12 years and one of their parents. Parents completed a survey that included four questions that assessed how frequently they used verbal cues to encourage their child to play outdoors. Points were assigned to each response and averaged across the 4 questions, and based on this average participants were assigned to quintiles. The survey included seven questions that asked parents to assess how frequently their child played outdoors outside of school hours. Points were assigned to each response and summed to create an active outdoor play frequency score. General linear models assessed associations between parental encouragement and outdoor play while controlling for individual, family, and neighborhood covariates. Results. The mean outdoor active play frequency score increased significantly across quintiles of the parental encouragement score as follows: 6.0 (standard error = 0.7) in quintile 1, 9.8 (0.6) in quintile 2, 11.4 (0.6) in quintile 3, 16.2 (0.9) in quintile 4, and 23.3 (1.3) in quintile 5. After adjusting for covariates, the mean outdoor active play frequency score was almost three times higher in the highest parental encouragement quintile than in the lowest quintile (20.4 vs. 7.8). Conclusions. Parents use of verbal cues to encourage their children to play outdoors was independently associated with outdoor active play among 7-12 year olds. PMID:26644990

    Full Text Available Abstract Background Dental decay is the most common childhood disease worldwide and most of the decay remains untreated. In the Philippines caries levels are among the highest in the South East Asian region. Elementary school children suffer from high prevalence of stunting and underweight. The present study aimed to investigate the association between untreated dental decay and Body Mass Index (BMI among 12-year-old Filipino children. Methods Data collection was part of the National Oral Health Survey, a representative cross-sectional study of 1951 11-13-year-old school children using a modified, stratified cluster sampling design based on population classifications of the Philippine National Statistics Office. Caries was scored according to WHO criteria (1997 and odontogenic infections using the PUFA index. Anthropometric measures were performed by trained nurses. Some socio-economic determinants were included as potential confounding factors. Results The overall prevalence of caries (DMFT + dmft > 0 was 82.3% (95%CI; 80.6%-84.0%. The overall prevalence of odontogenic infections due to caries (PUFA + pufa > 0 was 55.7% (95% CI; 53.5%-57.9% The BMI of 27.1% (95%CI; 25.1%-29.1% of children was below normal, 1% (95%CI; 0.5%-1.4% had a BMI above normal. The regression coefficient between BMI and caries was highly significant (p 0 as compared to those without odontogenic infections had an increased risk of a below normal BMI (OR: 1.47; 95% CI: 1.19-1.80. Conclusions This is the first-ever representative survey showing a significant association between caries and BMI and particularly between odontogenic infections and below normal BMI. An expanded model of hypothesised associations is presented that includes progressed forms of dental decay as a significant, yet largely neglected determinant of poor child development.

    Background Traumatic dental injuries to anterior teeth are a significant public health problem, not only because their prevalence is relatively high, but also because they have considerable impact on children’s daily lives. Traumatic dental injuries (TDIs) cause physical and psychological discomfort, pain and other negative impacts, such as tendency to avoid laughing or smiling, which can affect social relationships. Objectives This study aimed to assess the prevalence of traumatic dental injuries to anterior teeth among 12-year-old school children in Kashmir, India. Patients and Methods A cross-sectional study was conducted in private and government schools of India among 1600 schoolchildren aged 12 years. In addition to recording of the type of trauma (using Ellis and Davey classification of fractures, 1970), over jet, Angle’s molar relation and lip competence were also recorded. The socioeconomic status and academic performance of the study subjects were registered. The data obtained were compiled systematically and then statistically analyzed. The statistical significance for the association between the traumatic injury and the variables was analyzed using the chi-square test. Logistic regression was used to identify potential risk predictors of TDIs. Results The overall prevalence of TDI to anterior teeth was found to be 9.3%. The TDI to anterior teeth in male was more than female, but the difference was statistically nonsignificant (P < 0.01). Falls and sports were the most common causes of trauma in the present study. The highest potential risk factor for the occurrence of trauma was over jet. Academic performance was found to be significantly associated to TDI to anterior teeth, when analyzed in a multiple regression model. Conclusions It was concluded that the prevalence of traumatic dental injuries was 9.3%. Traumatic dental injuries among children exhibit complex interaction between the victims’ oral conditions and their behavior. Therefore

    A genotype G3P[14] rotavirus strain was identified in a 12year old child presenting to the Emergency Department of the Royal Children's Hospital, Melbourne, with gastroenteritis. G3P[14] strains have been previously identified in rabbits in Japan, China, the USA and Italy and a single lapine-like strain from a child in Belgium. Full genome sequence analysis of RVA/Human-wt/AUS/RCH272/2012/G3P[14] (RCH272) revealed that the strain contained the novel genome constellation G3-P[14]-I2-R3-C3-M3-A9-N2-T6-E2-H3. The genome was genetically divergent to previously characterized lapine viruses and the genes were distantly related to a range of human bovine-like strains and animal strains of bovine, bat and canine/feline characteristics. The VP4, VP6, NSP2, NSP3, NSP4 and NSP5 genes of RCH272 clustered within bovine lineages in the phylogenetic analysis and shared moderate genetic similarity with an Australian bovine-like human strain RVA/Human-tc/AUS/MG6/1993/G6P[14]. Bayesian coalescent analysis suggested these genes of RCH272 and RVA/Human-tc/AUS/MG6/1993/G6P[14] were derived from a population of relatively homogenous bovine-like ancestral strains circulating between 1943 and 1989. The VP7, VP1, VP2 and NSP1 genes shared moderate genetic similarity with the Chinese strain RVA/Bat-tc/CHN/MSLH14/2011/G3P[3] and the VP3 gene clustered within a lineage comprised of canine and feline strains. This strain may represent the direct transmission from an unknown host species or be derived via multiple reassortment events between strains originating from various species. The patient lived in a household containing domesticated cats and dogs and in close proximity to a colony of Gray-headed Flying-foxes. However, without screening numerous animal populations it is not possible to determine the origins of this strain. PMID:24780429

    Full Text Available OBJECTIVE: To describe the prevalence of dental fluorosis, to investigate its association with individual and contextual variables among 12-year-old schoolchildren, and to determine whether there were changes in the prevalence of this condition from 2003 to 2010.METHODS: This cross-sectional study used data from an oral health survey carried out in Goiânia, Goiás, in 2010 (n = 2,075, and secondary data from the files of the local health authority. Clinical data were collected through oral examinations in public and private schools. The dependent variable was the presence of dental fluorosis, assessed using the Dean Index. The independent individual variables were sociodemographic characteristics (the child's gender and race, and the mother's level of schooling and those related to clinical conditions (caries experience, evaluated using Decayed, Missing, and Filled teeth index; and presence of periodontal calculus and/or bleeding, evaluated using Community Periodontal Index. The contextual variables were linked to the school (type and existence of toothbrushing program and its geographic location in the city's health districts. The Rao-Scott test was performed, and the percentage difference between the prevalences in the period from 2003 to 2010 was calculated.RESULTS: The prevalence of dental fluorosis in 2010 was 18.7%, being distributed as very mild (11.2%, mild (4.4%, moderate (2.6%, and severe (0.5%. No significant association was found between prevalence of dental fluorosis and the investigated variables. The prevalence of fluorosis increased 230% from 2003 to 2010, and such difference was significant.CONCLUSIONS: The prevalence of dental fluorosis was low, predominantly of the very mild degree, has increased over a 7-year period, and was not associated with the individual or contextual factors studied.

    Childhood is a critical period in the development of obesity. Eating patterns established early in life track into later life. Therefore, parental approaches to feeding in their general parenting style, feeding styles, and specific feeding practices will have a profound impact on how children eat and grow. A systematic research review following PRISMA guidelines was conducted to identify, discuss and integrate recent research investigating the relationship between parenting styles, feeding styles, feeding practices, and body mass index (BMI) in children. Medline (Ovid), PsycINFO, Web of Science, and Food Science and Technology Abstracts were systematically searched using sensitive search strategies. Studies were limited to papers published in English between 2010 and February 2015 with participants aged 4-12 years old with outcomes including obesity, change in weight, or BMI. The search yielded 31 relevant quantitative peer-reviewed papers meeting all inclusion criteria: seven longitudinal, 23 cross-sectional, one randomized control trial. Associations between parenting style and child BMI were strongest and most consistent within the longitudinal studies. Uninvolved, indulgent or highly protective parenting was associated with higher child BMI, whereas authoritative parenting was associated with a healthy BMI. Similarly for feeding styles, indulgent feeding was consistently associated with risk of obesity within cross-sectional studies. Specific feeding practices such as restriction and pressure to eat were linked to BMI, especially within cross-sectional studies. Where child traits were measured, the feeding practice appeared to be responsive to the child, therefore restriction was applied to children with a high BMI and pressure to eat applied to children with a lower BMI. Behaviors and styles that are specific to the feeding context are consistently associated with child BMI. However, since obesity emerges over time, it is through longitudinal, carefully

    The oral health status of 6- and 12-year-old Filipino children was assessed in a representative national sample of 2030 6-year-old and 2022 12-year-old children, using WHO Basic Methods for Oral Health Surveys (4th edition, 1997) and the PUFA (pulpal involvement [P/p], ulceration caused by dislocated tooth fragments [U/u], fistula [F/f], and abscess [A/a]) index. A subsample of 242 12-year-old children was included to assess backward comparability between the 1998 Oral Health Survey that used WHO Basic Methods (3rd edition, 1987). The results showed that 97% of 6-year-old children had caries (mean dmft 8.4), 85% showed dental infection (mean pufa 3.4), 20% reported pain when examined. In all, 82% of 12-year-old children had caries (mean DMFT 2.9), 56% prevalence of pulp involvement (mean PUFA 1.0), and 16% reported pain when examined. Differences in methodology between the 1998 and the 2006 surveys are likely to have had an effect on the observed reduction in DMFT, indicating that the real caries prevalence had not changed much and remains very high.

    Full Text Available Crouzon syndrome or craniofacial dysostosis is a rare syndrome characterized by craniosynostosis, midfacial hypoplasia and exophthalmia. The abnormalities found in this syndrome change too much from case to case depending on the suture fusion order. We report a case of a 12 year old child and a mother showing variations in the dentofacial tissues clinically and radiographically. Subsequently, the application of digital software [Dolphin Imaging 11] enabled us to solve out the case as Crouzon syndrome by analyzing the skeletal and soft tissue alterations. An update of the effects of this syndrome on various systems and dentofacial features with emphasis on tooth abnormalities is documented.

    Objective The aim of the study was to investigate oral health-related knowledge, attitudes and habits and their relationship to perceived oral symptoms among 12-year-olds and differences between boys and girls. Material and methods The study population consisted of children (n = 588) in 15 randomly selected elementary schools in Turku, Finland. Associations between oral health-related habits, knowledge and attitudes with perceived oral symptoms and gender differences were evaluated with χ(2)-test, Mann-Whitney U-test and logistic regression analysis. Results Oral health promoting habits but not knowledge or attitudes associated significantly with absence of oral symptoms. Girls reported a higher percentage of several health promotional habits than boys. Girls reported more frequently gingival bleeding and less frequently dental calculus than boys did. The most common oral symptom was gingival bleeding. Conclusions The present findings suggest some gender-related differences in oral health habits, attitudes, as well as perceived oral symptoms in 12-year-olds. There seems, however, not to be gender differences in relation to knowledge or the association of health habits with perceived oral symptoms. It is important to maintain health promotion at schools and additional efforts should be aimed at translating knowledge into action. PMID:26881848

    The study investigated whether mental age in children, as assessed by the IQ in the Draw-A-Person (DAP) test (Naglieri, 1988), can be improved by practice. In addition, it was tested whether children needed novel content to keep up their performance level during test repetition. The DAP test was given to 6-, 8-, 10-, and 12-year-old children (N = 80) 3 times. In addition, they drew a police figure 3 times, with task sequence counterbalanced. Repeated drawings resulted in significant omission of detail and deterioration of scores, but the novel task instruction temporarily recovered the IQ scores. This did not occur in the reverse sequence of the tasks, with the less specified DAP instruction given in the 2nd half of the drawing series. Furthermore, structural regressions in the human figure drawing could be observed in individual cases. However, 12-year-olds did not need the external introduction of novel content to maintain their IQ score. Correlations showed that this age group redefined their drawing plan on each repetition, and often created unique figures on each occasion, even if the instruction had stayed the same. PMID:24188151

    Full Text Available Abstract Background In recent decades low-income countries experienced an increasing trend in dental caries among children, particularly recorded in 12-year olds, which is the principal WHO indicator age group for children. This increases the risks of negative affects on children's life. Some data exist on the oral health status of children in low-income countries of Southeast Asia. However, information on how oral health is associated with socio-behavioural factors is almost not available. The aims of this study were to: assess the level of oral health of Lao 12-year-olds in urban and semi-urban settings; study the impact of poor oral health on quality of life; analyse the association between oral health and socio-behavioural factors; investigate the relation between obesity and oral health. Methods A cross sectional study of 12-year old schoolchildren chosen by multistage random sampling in Vientiane, Lao P.D.R (hereafter Laos. The final study population comprised 621 children. The study consisted of: clinical registration of caries and periodontal status, and scores for dental trauma according to WHO; structured questionnaire; measurement of anthropometric data. Frequency distributions for bi-variate analysis and logistic regression for multivariate analysis were used for assessment of statistical association between variables. Results Mean DMFT was 1.8 (SEM = 0.09 while caries prevalence was 56% (CI95 = 52-60. Prevalence of gingival bleeding was 99% (CI95 = 98-100 with 47% (CI95 = 45-49 of present teeth affected. Trauma was observed in 7% (CI95 = 5-9 of the children. High decay was seen in children with dental visits and frequent consumption of sweet drinks. Missed school classes, tooth ache and several impairments of daily life activities were associated with a high dD-component. No associations were found between Body Mass Index (BMI and oral health or common risk factors. The multivariate analyses revealed high risk for caries for

    Twenty-seven children, with typical language development (TLD), 8-10 years old and 10-12 years old, were assessed with keystroke-logging in order to investigate their narrative writing. Measures of the writing process and the written product were used. One purpose was to explore how children produce written narratives in on-line production, and to relate the writing process to the written product. The results showed that those children who produced the final text faster, also wrote stories that comprised of more words. In the group of older children, children with better narrative ability used less pause time than those with worse ability, and the girls were faster writers than the boys. We believe that keystroke-logging gives valuable information for the assessment of young children's writing and that it is a potentially valid assessment tool for children from about 10 years of age.

    Background: radiogenic malignancies require cure of the primary disease and a prolonged survival. The introduction of high-volt technology in the 1950s and 1960s made radical radiotherapy feasible and successful in terms of higher cure rates and longer survival. We are already in a time when a higher number of patients with radiogenic secondary malignancies must be expected. Case report: a 12-year-old boy is reported who suffered from an advanced nasopharynx carcinoma and was treated with radical irradiation in 1983. 15 years later he developed a rare microcystic adnexal carcinoma of the auditory canal inside the volume of the target dose. The secondary malignant neoplasm was resected and required another radiation treatment (1 Gy b.i.d.) due to involved margins. Discussion and literature review: the entity of microcystic carcinoma is discussed with a review of the literature on biology, diagnosis, and treatment. (orig.)

    Full Text Available Pancreatic tumors are uncommon in children and rarely result in biliary obstruction. A previously well 12-year old female presented with a one-week history of fatigue, pruritis, and painless jaundice. Abdominal ultrasound demonstrated a mass in the pancreatic head associated with dilation of the common bile duct. Further workup included abdominal MRI, CT and endoscopic retrograde pancreaticogram (ERCP with biliary stenting. Octreotide scan did not reveal uptake in the pancreatic tumor. Percutaneous biopsies were consistent with a grade 2 pancreatic neuroendocrine tumor (NET. Preoperative imaging demonstrated involvement of the portal vein. The patient was brought the operating room for a pancreaticoduodenectomy and portal vein resection. Final pathology revealed a T3N1M0 pancreatic NET. The patient recovered uneventfully.

    Large pulmonary arteriovenous malformations (PAVMs) constitute an uncommon cause of central cyanosis with septic embolism and brain abscess. This large right to left shunt can lead to chronic severe hypoxemia and significant morbidity and mortality if untreated. Conservative parenchyma-sparing lung resection was used widely as treatment of choice. However, with the advent of embolotheraphy, it is considered the preferred mode of treatment with less invasiveness. We here report a 12-year-old boy with large aneurysmal pulmonary arteriovenous fistula presented with brain abscess and hemiparesis. He underwent thoracotomy and pneumonectomy for large PAVMs, and it was complicated with bleeding and massive blood transfusion. The patient developed acute renal failure as a postoperative complication and succumbed to it. We suggest proper look out for systemic collateral and their management by embolitheraphy either alone or in combination should be tried first. We also suggest median sternotomy and intrapericardial approach for pneumonectomy in such difficult situation can be helpful. PMID:27051111

    Full Text Available Younglim Kim, Suk-Bae MoonDepartment of Surgery, Kangwon National University Hospital, Kangwon National University School of Medicine, Chuncheon, South KoreaAbstract: Solid pseudopapillary neoplasm (SPN is a rare tumor of the pancreas that tends to grow silently in patients at a young age, to a large size and mass. We report here a case of a small-sized SPN detected incidentally in a 12-year-old girl following a traffic accident. The tumor was 3.5 cm in maximal diameter and was found to have hemorrhagic necrosis without a solid component. Laparoscopic spleen-preserving distal pancreatectomy was performed which cured the patient. SPN is generally accepted to be a low grade malignant tumor, but its clinical behavior is sometimes unpredictable. Tumor size and the proportion of solid portion of the tumor have both recently been identified as predictors of malignancy. Although the initial presentation in this case was that of the traffic accident, the subsequent detection of a small, totally cystic SPN, and then the complete eradication of the lesion, led to a favorable outcome for the patient. Long-term monitoring should prevent any chance of recurrence.Keywords: pancreatic neoplasm, children, distal pancreatectomy

    Previous studies have reported sex differences in wayfinding performance among adults. Men are typically better at using Euclidean information and survey strategies while women are better at using landmark information and route strategies. However, relatively few studies have examined sex differences in wayfinding in children. This research investigated relationships between route learning performance and two general abilities: spatial ability and verbal memory in 153 boys and girls between 6- to 12-years-old. Children completed a battery of spatial ability tasks (a two-dimension mental rotation task, a paper folding task, a visuo-spatial working memory task, and a Piagetian water level task) and a verbal memory task. In the route learning task, they had to learn a route through a series of hallways presented via computer. Boys had better overall route learning performance than did girls. In fact, the difference between boys and girls was constant across the age range tested. Structural equation modeling of the children’s performance revealed that spatial abilities and verbal memory were significant contributors to route learning performance. However, there were different patterns of correlates for boys and girls. For boys, spatial abilities contributed to route learning while verbal memory did not. In contrast, for girls both spatial abilities and verbal memory contributed to their route learning performance. This difference may reflect the precursor of a strategic difference between boys and girls in wayfinding that is commonly observed in adults. PMID:26941701

Methods In this descriptive cross sectional study, which was conducted in the 2009-2010 period, the study population included7-12 year-old first to fifth grade elementary school students in Sari. Sampling was multi-stage and stratified randomization at level of the target students. Student’s height and weight were measured using stediometer and digital scales. Body Mass Index (BMI was calculated. A questionnaire about feeding habits and socio-economic status(SES of families was used. Data collection was performed using phone interview with parents also the questionnaire’s records. Analysis was done in SPSS16 using appropriate statistical tests, p85% and 78 (12% were obese (BMI> 95%. Higher prevalence of obesity in the children with good socio economic status was found (p=0.001. Significant relationship between usage of fast food and obesity, and between school grade and obesity (p= 0.001 was found. Conclusion The overall prevalence of obesity in studied children was high, which suggests the need for serious attention in the health system, extensive studies, also designing and implementation of interventions with regard to childhood obesity.

    There are currently no studies available reporting intervention effects on breaking up children's sedentary time. This study examined the UP4FUN intervention effect on objectively measured number of breaks in sedentary time, number of sedentary bouts (≥ 10 mins) and total and average amount of time spent in those sedentary bouts among 10- to 12-year-old Belgian children. The total sample included 354 children (mean age: 10.9 ± 0.7 years; 59% girls) with valid ActiGraph accelerometer data at pre- and posttest. Only few and small intervention effects were found, namely on total time spent in sedentary bouts immediately after school hours (4-6PM; β = -3.51mins) and on average time spent in sedentary bouts before school hours (6-8.30AM; β = -4.83mins) and immediately after school hours in favor of children from intervention schools (β = -2.71mins). Unexpectedly, girls from intervention schools decreased the number of breaks during school hours (8.30AM-4PM; β = -23.45breaks) and increased the number of sedentary bouts on a weekend day (β = +0.90bouts), whereas girls in control schools showed an increase in number of breaks and a decrease in number of bouts. In conclusion, UP4FUN did not have a consistent or substantial effect on breaking up children's sedentary time and these data suggest that more intensive and longer lasting interventions are needed.

    This study aimed to determine the prevalence of dental fluorosis and its relationship to socioeconomic status, knowledge, and awareness among 12-year-old school children in Quetta, Pakistan. A cross sectional study was conducted among 349 school children aged 12 years in Quetta, Pakistan. By interviewing children and questionnaire for parents, socioeconomic status, knowledge, and awareness of fluorosis were collected. Dental fluorosis was examined using Dean's Index and Community Fluorosis Index. Prevalence of dental fluorosis was high (63.6%) among children with a majority of moderate and mild degree at 32.1% and 27.5%, respectively. The community fluorosis index was 1.6. While most children and parents had low-to-moderate levels of fluorosis knowledge, the majority of them worried about dental fluorosis. Most parents (84.8%) were uncertain about the condition of fluorosis in their children, and 87.4% did not know about fluorosis before. Dental fluorosis was found significantly associated with gender, family income, and parents' awareness (p ≤ 0.05). Multivariate analysis indicated that gender, and parent's awareness significantly predicted children's dental fluorosis. Knowledge and basic information regarding dental fluorosis is lacking in the community. Efforts in dissemination and communication about dental fluorosis should be increased in order to raise awareness and prevent the dental fluorosis in Pakistan. PMID:26513940

To establish the prevalence of restrictive eating problems, the overlap and association with attention-deficit/hyperactivity disorder (ADHD, and autism spectrum disorders (ASD and to estimate the heritability of eating problems in a general population sample of twins aged 9 and 12. Methods. Parents of all Swedish 9- and 12-year-old twin pairs born between 1993 and 1998 (n=12,366 were interviewed regarding symptoms of ADHD, ASD, and eating problems (EAT-P. Intraclass correlations and structural equation modelling were used for evaluating the influence of genetic and environmental factors. Cross-twin, cross-trait correlations were used to indicate a possible overlap between conditions. Results. The prevalence of eating problems was 0.6% in the study population and was significantly higher in children with ADHD and/or ASD. Among children with eating problems, 40% were screened positive for ADHD and/or ASD. Social interaction problems were strongly associated with EAT-P in girls, and impulsivity and activity problems with EAT-P in boys. The cross-twin, cross-trait correlations suggested low correlations between EAT-P and ADHD or EAT-P and ASD. Genetic effects accounted for 44% of the variation in liability for eating problems. Conclusions. In the group with eating problems, there was a clear overrepresentation of individuals with ADHD and/or ASD symptoms.

    2011-01-01

    Background The relative number of children meeting the minimal required dose of daily physical activity remains execrably low. It has been estimated that in 2015 one out of five children will be overweight. Therefore, low levels of physical activity during early childhood may compromise the current and future health and well-being of the population, and promoting physical activity in younger children is a major public health priority. This study is to gain insight into effects of a Physical Education based playground program on the PA levels during recess in primary school children aged 6-12. Methods/design The effectiveness of the intervention program will be evaluated using a prospective controlled trial design in which schools will be matched, with a follow-up of one school year. The research population will consist of 6-12 year old primary school children. The intervention program will be aimed at improving physical activity levels and will consist of a multi-component alteration of the schools' playground. In addition, playground usage will be increased through altered time management of recess times, as well as a modification of the Physical Education content. Discussion The effects of the intervention on physical activity levels during recess (primary outcome measure), overall daily physical activity and changes in physical fitness (secondary outcome measures) will be assessed. Results of this study could possibly lead to changes in the current playground system of primary schools and provide structured health promotion for future public health.

    Full Text Available Inhibitory control is the ability to suppress competing, dominant, automatic or prepotent cognitive processing at perceptual, intermediate, and output stages. Inhibitory control is a key cognitive function of typical and atypical child development. This study examined age-related trends of Stroop-like interference in 3–12-year-old children and young adults by administration of a computerized Stroop-like big–small task with reduced working memory demand. This task used a set of pictures displaying a big and small circle in black and included the same condition and the opposite condition. In the same condition, each participant was instructed to say ‘big’ when viewing the big circle and to say ‘small’ when viewing the small circle. In the opposite condition, each participant was instructed to say ‘small’ when viewing the big circle and to say ‘big’ when viewing the small circle. The opposite condition required participants to inhibit the prepotent response of saying the same, a familiar response to a perceptual stimulus. Results of this study showed that Stroop-like interference decreased markedly in children in terms of error rates and correct RT. There was no deterioration of performance occurring between the early trials and the late trials in the sessions of the day–night task. Moreover, pre-test failure rate was relatively low in this study. The Stroop-like big–small task is a useful tool to assess the development of inhibitory control in young children in that the task is easy to understand and has small working memory demand.

    Full Text Available Background: To organize community-oriented oral health promotion programs systematic analysis of the oral health situation would be needed, including information on oral health knowledge, attitudes, and practices (KAP. Aim: The aim of this study was to assess knowledge, attitude, and practice (KAP toward oral health among 11 to 12-year-old school children in a government-aided missionary school of Bangalore city. Materials and Methods: The study group comprised of 212 children (Male: 108; Female; 104 who were in the age group of 11-12 years studying in a government-aided missionary school of Bangalore city. Data on oral health KAP were collected by means of a self-administered questionnaire. Statistical significance was determined by Chi-square test. Results: This survey found that only 38.5% of the children brush their teeth two or more times a day. Pain and discomfort from teeth (35.1% were common while dental visits were infrequent. Fear of the dentist was the main cause of irregular visit in 46.1% of study participants. High proportion of study participants reported having hidden sugar at least once a day: soft drinks (32.1%, milk with sugar (65.9%, and tea with sugar (56.1%. It was found that 5.4% and 3.9% of study participants smoke and chew tobacco, respectively. Conclusion: Results of this study suggest that oral health KAP of study participants are poor and needs to be improved. Systematic community-oriented oral health promotion programs are needed to improve oral health KAP of school children.

    Background The UP4FUN intervention is a family-involved school-based intervention aiming at reducing and breaking up sitting time at home (with special emphasis on screen time), and breaking up sitting time in school among 10–12 year olds in Europe. The purpose of the present paper was to evaluate its short term effects. Methodology/Principal Findings A total of 3147 pupils from Belgium, Germany, Greece, Hungary and Norway participated in a school-randomized controlled trial. The intervention included 1–2 school lessons per week for a period of six weeks, along with assignments for the children and their parents. Screen time and breaking up sitting time were registered by self-report and total sedentary time and breaking up sitting time by accelerometry. The effect of the intervention on these behaviors was evaluated by multilevel regression analyses. All analyses were adjusted for baseline values and gender. Significance level was p≤0.01. No significant intervention effects were observed, neither for self-reported TV/DVD or computer/game console time, nor for accelerometer-assessed total sedentary time and number of breaks in sitting time. The intervention group, however, reported more positive attitudes towards (β = 0.25 (95% CI 0.11, 0.38)) and preferences/liking for (β = 0.20 (95% CI 0.08, 0.32)) breaking up sitting time than the control group. Conclusions/Significance No significant intervention effect on self-reported screen time or accelerometer-assessed sedentary time or breaks in sitting time was observed, but positive effects on beliefs regarding breaking up sitting time were found in favor of the intervention group. Overall, these results do not warrant wider dissemination of the present UP4FUN intervention.

    Full Text Available BACKGROUND: The association between objectively assessed sedentary time and metabolic risk factors in childhood have rarely been studied. Therefore, we examined the independent relationship between objectively assessed and self-rated sedentary time and indicators of metabolic health in Dutch and Hungarian 10-12 year olds. METHODOLOGY/PRINCIPAL FINDINGS: We performed a cross-sectional survey in primary schools. Participants were Dutch and Hungarian girls (n = 73, aged 12.2 ± 0.6 years, 18% overweight/obese and boys (n = 69, aged 12.2 ± 0.7 years, 38% overweight/obese. Sedentary time and physical activity were assessed by the Actigraph accelerometer. TV and PC time were assessed by self-report. Adiposity indicators included body weight, height, and waist circumference (WC. Fasting plasma glucose, C-peptide, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and triglycerides were determined in capillary blood and summed into a metabolic risk score. Linear regression analyses were adjusted for physical activity, number of sedentary bouts and WC. Children spent on average 7.6 hours of their daily waking time in sedentary behavior and self-reported 116 ± 64 min/day watching TV and 85 ± 57 min/day using the computer. Comparing the 1(st and 4(th quartile of objectively assessed sedentary time, C-Peptide levels, WC and BMI were significantly higher in the most sedentary quartile, while the difference in metabolic risk score was borderline significant (p = 0.09. Comparing the 1(st and 4(th quartile of TV time, BMI was significantly higher in the most sedentary quartile, while the difference in WC score was borderline significant (p = 0.06. In the adjusted linear regression analysis we found no significant association of sedentary time with metabolic risk. CONCLUSIONS/SIGNIFICANCE: Although BMI and WC were higher in the most sedentary versus the least sedentary children; we found no further evidence that more

    Full Text Available Abstract Background Over the last decade notable progress has been made in developed countries on monitoring smoking although experimenting with cigarettes and smoking in young people remains a serious public health problem. This paper reports a cross-sectional study at the beginning of the 3-year follow-up community study TA_BES. The aim was to study the prevalence of smoking in addition to determining predictive factors for when smoking commences in a representative population of 12-year-old first year compulsory secondary education students. Methods Twenty-nine secondary schools (N = 29 from an area of Catalonia participated in the study. In these schools 2245 students answered a questionnaire to study the attitudes, behaviors, and tobacco consumption in the subject's surrounding circle and family in relation to smoking; carbon monoxide measurements were taken by means of co-oximetry on 2 different occasions. A smoker was defined as a student who had smoked daily or occasionally in the last 30 days. For non-smokers the criteria of not considering was set up for those who answered that in the future they would not be smokers and considering those who answered that they did not rule out becoming a smoker in the future. Results Among the total 2245 students included in the analysis 157(7% were classified as smokers. Among non-smokers we differentiated between those not considering smoking 1757 (78.3% and those considering smoking 288 (12.8%. Age is among the factors related to commencing smoking. The risk of becoming a smoker increases 2.27 times/year. The influence of the group of friends with a very high risk for boys OR 149.5 and lower, albeit high, in girls OR 38.1. Tobacco consumption of parents produces different effects in young people. A smoking father does not produce alterations in the smoking behavior of young people. However having a smoking mother or former smoking is a risk factor for boys and a protective factor for girls. We

    Full Text Available Growing evidence shows that metabolic syndrome (MetS is already starting in childhood however there is no consensus regarding how to diagnose this condition in pediatric population. Studies in adults show that altered levels of specific micro-RNAs are related with components of the MetS.We determined the plasma levels of four MetS-associated micro-RNAs (miR-126, miR-132, mir-145 and Let-7e in 10 to 12 years old children with or without MetS traits.Pediatric subjects were selected from a cohort of 3325 school-age children, and clustered by the absence (control, n = 30, or the presence of 1 (n = 50, 2 (n = 41 or 3 (n = 35 MetS traits according to Cook´s criteria. Micro-RNAs were isolated from plasma, and levels of miR-126, miR-132, miR-145 and Let-7e were determined by Taqman qPCR.Regression analysis of the different MetS traits regarding the different miRNAs analyzed showed that Let-7e presented a negative association with HDL-C levels, but a positive correlation with the number of MetS traits. Levels of miR-126 presented a positive correlation with waist circumference, waist to hip ratio, BMI, and plasma triglycerides and VLDL-C. Levels of miR-132 showed a positive correlation with waist to hip ratio. Plasma levels of Let-7e were increased (~3.4 fold in subjects with 3 MetS traits, and showed significant AUC (0.681; 95%CI = [0.58, 0.78]; p < 0.001 in the ROC analysis which were improved when miR-126 was included in the analysis (AUC 0.729; p < 0.001. In silico analysis of the interaction of proteins derived from mRNAs targeted by Let7 and miR-126 showed an important effect of both Let-7e and miR-126 regulating the insulin signaling pathway.These results suggest that changes in the plasma levels of Let-7e and miR-126 could represent early markers of metabolic dysfunction in children with MetS traits.

  14. Beyond captions: linking figures with abstract sentences in biomedical articles.

    Directory of Open Access Journals (Sweden)

    Joseph P Bockhorst

    Full Text Available Although figures in scientific articles have high information content and concisely communicate many key research findings, they are currently under utilized by literature search and retrieval systems. Many systems ignore figures, and those that do not typically only consider caption text. This study describes and evaluates a fully automated approach for associating figures in the body of a biomedical article with sentences in its abstract. We use supervised methods to learn probabilistic language models, hidden Markov models, and conditional random fields for predicting associations between abstract sentences and figures. Three kinds of evidence are used: text in abstract sentences and figures, relative positions of sentences and figures, and the patterns of sentence/figure associations across an article. Each information source is shown to have predictive value, and models that use all kinds of evidence are more accurate than models that do not. Our most accurate method has an F1-score of 69% on a cross-validation experiment, is competitive with the accuracy of human experts, has significantly better predictive accuracy than state-of-the-art methods and enables users to access figures associated with an abstract sentence with an average of 1.82 fewer mouse clicks. A user evaluation shows that human users find our system beneficial. The system is available at http://FigureItOut.askHERMES.org.

    Full Text Available Abstract Background To determine the prevalence, intensity and extent of the Oral Impacts on Daily Performances associated with self-perceived malocclusion among Peruvian schoolchildren. Methods Eight hundred and five children aged 11 to 12 years attending 4 of 7 randomly selected schools linked to a Health Centre in Lima, Peru, participated in the study. The Spanish (PeruChild-OIDP was used to assess the prevalence, intensity and extent of oral impacts on 8 daily performances (eating, speaking, teeth cleaning, sleeping, smiling, studying, emotion and social contact. Self-perceived malocclusion included complaints about position of teeth, spacing of teeth and deformity of mouth or face. The prevalence of oral impacts was compared by covariables using the Chi-square test, whereas the intensity and extent of oral impacts were compared by covariables through the Mann-Whitney test. Results Only 15.5% of children reported impacts associated with self-perceived malocclusion during the last 3 months. Of them, 18.4% reported impacts of severe or very severe intensity and 76.0% reported impacts on only one daily performance. Psychosocial activities such as smiling, emotion and social contact were the most frequently and severely impacted everyday activities. Conclusion Impacts of self-perceived malocclusion primarily affected psychological and social everyday activities. These findings provide further evidence to support the importance of psychological and social components of oral health on children's lives.

    Full Text Available Abstract Introduction McCune-Albright syndrome is a complex inborn disorder due to early embryonal postzygotic somatic activating mutations in the GNAS1 gene. The phenotype is very heterogeneous and includes polyostotic fibrous dysplasia, typically involving the facial skull, numerous café-au-lait spots and autonomous hyperfunctions of several endocrine systems, leading to hyperthyroidism, hypercortisolism, precocious puberty and acromegaly. Case presentation Here, we describe a 12-year-old Caucasian girl with severe facial involvement of fibrous dysplasia, along with massive acromegaly due to growth hormone excess and precocious puberty, with a prolactinoma. Our patient was treated with a bisphosphonate and the prolactin antagonist, cabergoline, resulting in the inhibition of fibrous dysplasia and involution of both the prolactinoma and growth hormone excess. During a follow-up of more than two years, no severe side effects were noted. Conclusion Treatment with bisphosphonates in combination with cabergoline is a suitable option in patients with McCune-Albright syndrome, especially in order to circumvent surgical interventions in patients suffering from polyostotic fibrous dysplasia involving the skull base.

Un reconocimiento oportuno puede prevenir una anemia ferropénica, etapa final y grave de dicha deficiencia, insuficientemente conocida en nuestro país. El objetivo de este estudio fue determinar los valores hematológicos en adolescentes y conocer las prevalencias de anemia y deficiencia de hierro. Definidas como a anemia: hematocrito (Hto Iron deficiency is highly frequent among adolescents. Its early detection can prevent the development of a ferropenic anemia, a serious condition. The problem has not been well studied in our country. The purpose of this work was to determine the frequency of iron deficiency and anemia in adolescents. The criteria considered were: hematocrit below 38%, b saturation transferrin below 16%, c ferritin below 15 ng/ml. The study was carried out in 2.265 schoolchildren, 12 years old, of both sexes, in urban and periurban areas in the city of San Salvador de Jujuy (1.250 a.s.l.. The following parameters were measured: hematocrit as well as serum iron and total iron binding capacity, both by colorimetric method. Ferritin was measured by ELISA. Anemia was not found. Iron deficiency as estimated by the iron functional component, was found in 25% of girls and 21% of boys and, through iron stores, in 28% of girls and 18% of boys. Iron deficiency stores in both sexes is the more relevant alteration, indicating that the population sample here studied constitutes a highly vulnerable group. The early detection of iron deficiency will help physical and intellectual development so that adequate sanitary policies are necessary for its prevention.

  10. TP53 mutation p.R337H in gastric cancer tissues of a 12-year-old male child - evidence for chimerism involving a common mutant founder haplotype: case report

    International Nuclear Information System (INIS)

    Gastric adenocarcinoma is rare in children and adolescents, with about 17 cases under age 21 in the world's literature. We report a case of invasive well-differentiated metastatic gastric cancer in a Brazilian 12-year-old boy without documented familial history of cancer. The patient, diagnosed with metastatic disease, died seven months after surgery. DNA from intra-surgical specimens revealed a TP53 mutation at codon 337 (p.R337H) in samples with neoplastic cells (dysplasia, tumor and metastasis) but not in non-transformed cells (incomplete intestinal metaplasia and non-involved celiac lymph node). In all mutation-positive tissues, p.R337H occurred on the same background, a founder allele identified by a specific haplotype previously described in Brazilian Li-Fraumeni syndrome patients. The same mutant haplotype, corresponding to a founder mutation present in 0.3% of the general population in Southern Brazil, was found in the genome of the father. Presence of this inherited haplotype in the tumor as well as in the father's germline, suggests a rare case of microchimerism in this patient, who may have harbored a small number of mutant cells originating in another individual, perhaps a dizygotic twin that died early in gestation. This case represents one of the earliest ages at diagnosis of gastric cancer ever reported. It shows that cancer inheritance can occur in the absence of an obvious germline mutation, calling for caution in assessing early cancers in populations with common founder mutations such as p.R337H in Southern Brazil

    Full Text Available Abstract Background Cycling to school has been identified as an important target for increasing physical activity levels in children. However, knowledge about correlates of cycling to school is scarce as many studies did not make a distinction between walking and cycling to school. Moreover, correlates of cycling to school for those who live within a distance, that in theory would allow cycling to school, stay undiscovered. Therefore, this study examined individual, social and physical environmental correlates of never and always cycling to/from school among 10 to 12 year old Belgian children living within a 3.0 km distance from school. Methods 850 parents completed a questionnaire to assess personal, family, behavioral, cognitive, social and physical environmental factors related to the cycling behavior of their children. Parents indicated on a question matrix how many days a week their child (1 walked, (2 cycled, was (3 driven by car or (4 public transport to and from school during fall, winter and spring. Multivariate logistic regression analyses were conducted to examine the correlates. Results Overall, 39.3% of children never cycled to school and 16.5% of children always cycled to school.

    from a representative sample of 1,400 children were collected and analyzed in a cross-sectional study (year 2002. All subjects were clinically evaluated by one of two calibrated and standardized examiners. Results: 28.6% children were caries free in both dentitions. Caries prevalence in primary teeth in 6-years-old children was 72.6% and 45.0% in permanent teeth in 12-years-old children. Mean deft and DMFT were 2.98 ± 2.93 (n = 1,125 and 0.65 ± 1.43 (n = 1,379, respectively. The SiC at 12 years of age was 4.12. Children with caries experience in primary teeth were more likely to have caries in permanent teeth (odds ratio = 2.48; 95% confidence interval, 1.66-3.79 than children without caries in primary teeth. Conclusion: Low caries prevalence and experience were observed in the permanent dentition, with a substantial proportion of filled teeth. Such favorable finding was not observed in the primary dentition. Levels of caries failed to meet the oral health goal of FDI/WHO for the year 2000 in 6-years-old. However, the levels found in 12-year-olds had already met the goal for 2000. The present findings confirmed prior reports that the caries experience in primary teeth is associated with the experience of caries in permanent teeth.

    Background: The 12 years-old children population is worldwide taken as a reference age to compare the buccal health condition of different countries, by means of various indicators that measure the presence of the main buccal diseases. The knowledge of these epidemiological profiles generates information to guide the services planning policies of the Primary Health Care. Objective: To characterize 12 years-old population's buccal health condition. Methods: Cross- sectional descriptive correlative study with a stratified probabilistic sample of 90 children starting from a universe conformed by the 269 adolescents that constitute the total of the 12 years old population of the Health Care Area VIII in Cienfuegos municipality. Pearson’s chi-square and Mantel-Haenszel lineal tendency tests were used with the determination of the relative risk and reliance intervals of 95%. Results: The decay prevalence reached 54, 4%. The COP-D index was 2, 45 being the decayed component the major percentage with 4.6%. The periodontal disease was more frequent in boys than in girls, with 54, 9% and 30, 8% respectively. 80,9% of the segments is healthy. In those affected, the calculation prevailed in 11,7%. It was determined that faulty obturations, inheritance and faulty buccal hygiene were the most affecting risk factors for children with decays, while in the periodontal disease it was faulty buccal hygiene. Malocclusions presented a prevalence rate of 40%. Out of which, 55,6% required secondary level attention. Those with habits present a risk 2 times superior of making sick. The sick epidemiological category was present in 77,8% of the total.

    Full Text Available Neste estudo ecológico o objetivo foi analisar o cumprimento de metas da OMS para a cárie dentária no ano 2000 em Minas Gerais, identificando fatores associados à variação no CPO-D médio e na ocorrência de CPO-D 3, entre crianças de 12 anos, e no percentual de livres de cáries aos cinco anos. Foram utilizados dados secundários de diferentes fontes. As técnicas de regressão linear e regressão logística múltiplas foram aplicadas nas análises das variáveis dependentes numéricas e dicotômica consideradas. Indicadores sócio-econômicos e da oferta/utilização de serviços odontológicos foram empregados como variáveis explicativas potenciais. As metas expressas pelo CPO-D 3 aos 12 anos e pelo percentual mínimo de 50% de crianças livres de cárie aos cinco anos foram atingidas por 37% e 9% dos municípios, respectivamente. De modo geral, as variáveis dependentes mostraram-se associadas ao nível sócio-econômico, não se identificando associações com as variáveis relativas à atenção odontológica. Os resultados não devem ser generalizados, mas indicam iniqüidades na saúde bucal e o papel desempenhado por fatores sócio-econômicos e a fluoretação da água.The aim of this ecological study was to analyze to what extent World Health Organization goals were met in relation to dental caries in 2000 in Minas Gerais State, Brazil, identifying factors associated with variation in DMFT and the occurrence of DMFT 3 among 12-year-old children and in the percentage of caries-free 5-year-olds.

    fluorosis, 45.9% of the children had TFI 1, 6.1% TFI 2 and 0.9% TFI 3. A polarization of the experience of caries and gingivitis was observed in the studied population. Only 14.4% of the students had DMFS higher than 7. A small percentage of children (12% presented with BI ³ 40%. The experience of caries and gingivitis of 12-year-old schoolchildren in Porto Alegre is comparable to that of children from developed countries. That probably results from the intense utilization of fluoride, which is also causing an increased prevalence of fluorosis. The severity of fluorosis does not justify any public health measure. The results show that the employed public health measures are effective, although part of the population still needs additional care.

    Full Text Available The aim of this research was to investigate the effect of co-authorship and self-citation on the citation rates of Iranian indexed articles in Web of Science (WoS. Research population included Iranian indexed articles in WoS in 2007 which had been received at least one citation. Numbers of articles in the time of research (October & November 2010 was 7355, which 390 of them, using stratified random sampling, was selected as sample. Research results showed that co-authored articles have received more citations than single-authored ones and this difference was statistically significant. On the other hand, self-citation exclusion has significantly reduced the citation rates of both co-authored and single-authored articles. After self-citation exclusion, existing difference between citation rates of co-authored and single-authored articles lost its significance. So, it can be concluded that self-citation exclusion led to reduction of citation rates of Iranian indexed articles in WoS, but this exclusion affected co-authored articles citation rates more than single-authored ones. In other words, high citation of Iranian co-authored articles in comparison with single-authored articles has been affected mainly by self-citation, not by foreign citation. This finding, which was our contribution, contradicted with results of previous researches.

    Full Text Available The present study aimed to evaluate the need for orthodontic treatment in Brazilian schoolchildren presenting both late mixed dentition and early permanent dentition as well as to determine the possible factors associated with this necessity. Our randomly selected sample consisted of 407 schoolchildren aged between 9 and 12 years from Nova Friburgo (State of Rio de Janeiro, Brazil. All the children were evaluated according to the two components of the Index of Orthodontic Treatment Need (IOTN, namely, the Dental Health Component (DHC and the Aesthetic Component (AC. Data analysis involved multiple logistic regression. Definite need for orthodontic treatment was found in 34.2% and 11.3% of the children according to, respectively, DHC and AC. The most prevalent malocclusions included the following: contact point displacement (crowding, crossbite, and increased overjet. Male gender, permanent dentition and aesthetic reasons were factors associated with a great need for orthodontic treatment. It was concluded that about one-third of the children evaluated had a definite need for orthodontic treatment. This necessity was greater in the permanent dentition, thus emphasizing the importance of an early identification of malocclusions and a timely referral of patients for treatment. The correlation between AC and DHC was considered important since they involve distinctive characteristics.

    inherited with mutations leading to abnormalities in cardiac ion channel function. Mutations in KCNQ1 are the most common cause of LQTS. Although rare, mutations in KCNQ1 also can cause familial AF. This report describes a child with a KCNQ1 missense mutation who uniquely expresses concomitant AF and LQTS. Due to the potential for increased morbidity and mortality, young patients who present with AF and a family history suggestive of inherited arrhythmias should trigger further investigation for LQTS and subsequent familial genetic counseling.

    Full Text Available The cause for severe, recurrent lower gastrointestinal (LGI bleeding in children can usually be diagnosed readily by means of the commonly used investigative/diagnostic techniques such as colonoscopy, laparoscopy ± laparotomy. Occasionally less commonly used investigations may be necessary to look for more elusive causes of LGI bleeding such as capsule endoscopy, angiography, technetium-99m (99m Tc-labeled red blood cell (RBC scintigraphy, cross-sectional imaging such as CT/MRI (including angiography and laparotomy combined with on-table small bowel enteroscopy. We report a case of severe, recurrent LGI bleeding that had occurred over several years, where the cause remained elusive despite numerous investigations and interventions. The etiology of this was eventually found to be a gastric duplication cyst infiltrating into adjacent transverse colon and causing bleeding from peptic ulceration in the colon. The process by which this diagnosis was made and the lessons learned are discussed.

    Full Text Available The aim of this study was to evaluate the prevalence of caries-free children using DMFT and significant caries (SiC indexes in different caries prevalence groups in cities of the region of Campinas, São Paulo State, Brazil. The methodology proposed by the World Health Organization (1997 was used for caries diagnosis in 2,378 individuals. According to the DMFT index obtained in each evaluated city, 3 prevalence groups with representative samples were formed, being classified as low, moderate and high. SiC index was used to classify the one third of the population with the highest caries prevalence. In the low prevalence group, 32.4% of the children were caries free (DMFT=0, with mean DMFT of 2.29 and SiC index of 4.93. In the moderate prevalence group, 21.8% of the children were caries free, with mean DMFT of 3.36 and SiC of 6.74. Only 6.9% of the children in the high prevalence group were caries free and the mean DMFT was 5.54 (SiC=9.62. There was a great heterogeneity in dental caries distribution within the studied population, as well as a high caries prevalence considering the 3 classifications. Other indexes besides DMFT could be used to improve oral health assessment during establishment of the treatment plan and intervention.

    Full Text Available Objective:To determine whether arch height has an effect on the health-related quality of life of schoolchildren.Methods:One hundred and thirteen schoolchildren attended an out-patient centre where self-reported data were recorded, their feet were classified into one of three groups according to their arch index (high, normal or low and the scores obtained from the Foot Health Status Questionnaire (FHSQ - Spanish version were compared.Results:The groups with high, low and normal arch recorded lower scores in Section One for the general foot health and footwear domains and higher scores in foot pain and foot function. In Section Two they obtained lower scores in general health and higher scores in physical activity, social capacity and vigour.Conclusions:Comparison of the scores obtained reveals that arch height has a negative impact on quality of life. Given the limited extent of available evidence in respect of the aetiology and treatment of foot diseases and deformities, these findings reveal the need to implement programmes to promote foot health and carry out further research into this commonly occurring disabling condition.

    Full Text Available Reactive arthritis comprises a subgroup within infection-associated arthritides in genetically susceptible hosts. Researchers and clinicians recognize two clinical forms of reactive arthritis which occurs after genitourinary tract infection and after gastrointestinal tract infection. Chlamydia infection has been implicated as the most common agent associated with post-venereal reactive arthritis. Studies have proposed Shigella infection, Salmonella infection, or Yersinia infection as the microorganisms responsible for the post-dysenteric form. The human leukocyte antigen (HLA-B27 antigen is the best-known predisposing factor. We report a case of HLA-B27-associated reactive arthritis after Salmonella enteritis at Pusan National University hospital.

En Chile se ha observado un aumento sostenido de la presencia de obesidad y sobrepeso en niños. Sin embargo, se desconoce el nivel de presencia y la dinámica de las conductas alimentarias problemáticas mencionadas en niños chilenos. El objetivo de esta investigación fue estudiar la relación entre la alimenta-ción restringida, externa y emocional y las variaciones en el Índice de Masa Corporal (IMC en niños chilenos. Consecuentemente, 453 niños entre 7 a 12 años respondieron el Cuestionario Holandés de Conducta Alimentaria para niños. Además, se obtuvieron datos antropométricos. Se encontró una relación positiva entre la alimentación restringida y el IMC y una correlación negativa entre alimentación externa y el IMC. La alimentación emocional demostró una relación inversa modesta con el IMC. Se observó una significativa interacción entre la conducta problemática y estado nutricional (normopeso, sobrepeso, obesidad. La alimentación restringida fue característica de los niños con obesidad mientras que la alimentación externa, de los niños con normopeso. Estos resultados sugieren que la conducta alimentaria problemática y su relación con el peso corporal son similares a los estudios descritos en Europa. © 2012 Asociación Española de Psicología Conductual.Publicado por Elsevier España, S.L.

    It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis-stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

    This cross-sectional survey was carried out to assess epidemiological data concerning dental injuries to the permanent incisors of Syrian children. It included 1087 children aged 9 to 12 years, of both sexes, randomly selected from public and private primary schools in Damascus. The response rate was 100%. The prevalence of traumatic injuries to the permanent incisors rose from 5.2% at the age of 9 years to 11.7% at the age of 12 years (P = 0.007). The difference in prevalence between boys and girls was not statistically significant (P > 0.05). The majority (59.8%) of children who had experienced injuries to the permanent incisors reported that they were not taken to the dentist for evaluation or treatment of the damage. Among those children who had experienced traumatic injuries to the teeth 93.1% presented with untreated damage. Because some injuries were minor, such as small enamel fractures, the proportion of children who needed treatment was 63.2%. There was a tendency for children with an incisal overjet greater than 5 mm to have experienced dental injuries (P = 0.06). Children with inadequate lip coverage were more likely to have experienced dental injuries than those with adequate lip coverage (P = 0.000). The most common reported cause of injuries to the permanent incisors was violence (42.5%), followed by traffic accidents (24.1%), collisions with people or inanimate objects (16.0%) and falls (9.1%). In conclusion, traumatic dental injury may pose a serious dental public health problem. PMID:10530154

    BACKGROUND: Little is known about the quality of life (QoL) of disabled children. We describe self-reported QoL of children with cerebral palsy, factors that influence it, and how it compares with QoL of the general population. METHODS: 1174 children aged 8-12 years were randomly selected from...... eight population-based registers of children with cerebral palsy in six European countries and 743 (63%) agreed to participate; one further region recruited 75 children from multiple sources. Researchers visited these 818 children. 318 (39%) with severe intellectual impairment could not self-report; 500.......5-5.9) and autonomy (3.3, 0.9-5.7); and speech difficulties with reduced mean for relationships with parents (4.5, 1.9-7.1).

    Full Text Available Background and Aim: Learning disability(LD is one of the most prevalent problems among elementary school children. Approximately 10 percent of all elementary school children suffer from this problem. It has been determined that learning disability is predominantly accompanied with subtle impairment in central auditory nervous system. The main idea of this study was to evaluate middle latency auditory evoked potential (MLAEPs in learning disabled children. Materials and Method: This cross-sectional study investigated middle latency auditory evoked potential in children with learning disability (n = 31 compared to normal children (n = 31. Latencies and amplitudes of MLAEPs results with different stimulus intensity and binaural stimulation were compared between two groups. Results: Compared to control group, learning disabled children exhibited smaller amplitudes for all the components except the right ear Na and Pa. There is no significant difference between two groups for latencies of the components. Conclusion: It seems that middle latency auditory evoked potential may be useful in diagnosis and evaluation of learning disabled children although more investigation is required.

    2012-01-01

    Full Text Available Background and Aim: Childhood overweight and obesity are becoming a major public health concern all over the world. Change in lifestyles and economic growth have led to sedentary lifestyle and altered dietary patterns. There are conflicting reports in the literature regarding the association between body mass index (BMI and dental caries from various parts of the world. The aim of the present study was to determine if there is an association between BMI-for-age and dental caries in children and to find out the role of diet with respect to BMI-for-age and dental caries. Materials and Methods: Demographics and anthropometric measurements were obtained for 600 children and BMI-for-age was calculated. Clinical examination for dental caries was carried out following WHO criteria. A diet recording sheet was prepared and children/parents were asked to record the dietary intake for 3 days. Data obtained were statistically analyzed using Chi-square, analysis of variance (ANOVA, and multiple linear regression. Results: After excluding improperly filled diet recording sheets, 510 children were included in the study. Caries prevalence was more in obese children than in other BMI groups. Caries scores increased as BMI-for-age increased, though this was not statistically significant. Consumption of fatty foods and snacks was more with obese children compared to other groups. A correlation was found between caries and snacks. Conclusion: Dental caries scores showed no relationship between BMI-for-age in children. Both snacks and fatty food items were consumed more by obese children, which seeks attention.

    Results: The mean of body temperature was different in the three sites. The difference between right and left ear was not significant, but the difference between esophagus –rectum, esophagus-tympanum and rectum-tympanum was significant (P<0.001. All changes in four places showed that in hypothermia phase the reduction of temperature in ears was more than esophageal and rectal temperature, and in rectal, it was more than esophageal temperature. Conclusion: All sites are sensitive to changes of body temperature and they can show core temperature of body well, but since differences between all sites in four phases are not same, we cannot use just one of them to reach the temperature of other sites.

    Tics are the most frequent movement disorder in children and they are most prevalent during the school-age years. Most tics are transitory; however, certain tics can be chronic, causing negative repercussions at school, within the family, and socially. In some cases, tics are associated with obsessive compulsive disorder, attention-deficit hyperactivity disorder (ADHD) and other conditions that require diagnosis and prompt treatment. In South America, there are no indexed studies determining the prevalence of tics in school-age children. The aim of this study was to establish the prevalence of tics in schoolchildren aged 6 to 12 years. From 16 000 students aged 6 to 12 years who were enrolled in first to fifth grade, a sample of 346 school-aged children was chosen via a multistage sampling process that randomized the educational systems in terms of proportional size and the stratification between public and private schools and adjusted for the design effect. The students were screened and those who were positive for tics underwent clinical evaluations and semistructured interviews by the researchers to determine the prevalence of the disease. The parents and teachers of 323 students returned our surveys (93.3%). One hundred thirty-eight students (42.7%) were considered positive for tics based on parents' and teachers' reports. The clinical evaluation established a 17.97% prevalence of tics (58 students), and 25 students (43.2%) also met diagnostic criteria for ADHD. Of the students with tics, 27.6% presented with transitory tics, and 72.4% presented with chronic tics. Gilles de la Tourette syndrome was detected in 11 of the children (3.4%). The average age of child with tics was 9 ± 1.5 years, and the majority of the children with tics attended third grade at a basic primary school. Children from public and private schools were equally likely to present with tics. Tics are noteworthy in our field and are associated with other neurobehavioral disorders, such as ADHD. Both tic disorders and ADHD require diagnosis and prompt treatment to promote social and school performance.

    It has been reported that borderline personality related characteristics can be observed in children, and that these characteristics are associated with increased risk for the development of borderline personality disorder. It is not clear whether borderline personality related characteristics in children share etiological features with adult borderline personality disorder. We investigated the etiology of borderline personality related characteristics in a longitudinal cohort study of 1,116 pairs of same-sex twins followed from birth through age 12 years. Borderline personality related characteristics measured at age 12 years were highly heritable, were more common in children who had exhibited poor cognitive function, impulsivity, and more behavioral and emotional problems at age 5 years, and co-occurred with symptoms of conduct disorder, depression, anxiety, and psychosis. Exposure to harsh treatment in the family environment through age 10 years predicted borderline personality related characteristics at age 12 years. This association showed evidence of environmental mediation and was stronger among children with a family history of psychiatric illness, consistent with diathesis–stress models of borderline etiology. Results indicate that borderline personality related characteristics in children share etiological features with borderline personality disorder in adults and suggest that inherited and environmental risk factors make independent and interactive contributions to borderline etiology.

  20. Perioral Dermatitis after Dental Filling in a 12-Year-Old Girl: Involvement of Cholinergic System in Skin Neuroinflammation?

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available The etiopathogenesis of perioral dermatitis (PD is still unknown and, consequently, medical treatment is difficult, not precisely defined, and often unsatisfactory. On the basis of a peculiar case that appeared soon after multiple dental fillings with a mercury-containing amalgam, we proposed that neurogenic inflammation could play a role in the pathogenesis of PD. According to the new findings provided by clinical and basic research, neurogenic inflammation has a relevant part in the pathogenesis of many cutaneous diseases. We report a similar case of PD, taking into account, more specifically, the possible involvement of the cholinergic system. Also in this case, PD seems to be mainly related to the mercury contained in dental fillings and/or its organic compounds formed by oral/gut bacteria. We examined the possible role of these substances as causes of PD, providing new information on the possible cross-talk between neuroimmunodermatology and potential triggers of PD.

    Several studies investigating the relationship between body mass index (BMI), waist circumference (WC), and/or body fat (BF) with macronutrient composition of the diet have suggested that dietary composition may play an important role to overweight/obesity in childhood, but its relation remains inconclusive. The aim was to assess the association between energy intake (EI) and macronutrient diet composition with overweight/obesity among children.Nonrandomized cohort study including 396 Italian children and preadolescents (9-13 years old), 200 overweight/obese and 196 normal-weight. The children's weight, height, WC, and food intake were measured.Reported EI was higher in overweight/obese than in nonoverweight children; however, after body weight was considered, the overweight/obese children had less EI than their leaner counterparts. Percentages of EI from proteins, SFA, MUFA and PUFA (in males), and dietary fiber (g/1000 kcal) were higher in the overweight/obese children than in the leaner ones. EI from carbohydrates and fats was lower in overweight/obese males and females, respectively. Positive correlations between BMI and waist-to-height ratio with EI from proteins were found in males (r = 0.296, P regression, the highest EI from proteins were associated with higher odds ratio for overweight/obesity, while the lowest EI from carbohydrates was associated with higher odds ratio for overweight/obesity in males.Reported EI of overweight/obese children was higher than nonoverweight peers. Overweight/obese children had higher intakes of proteins compared with nonoverweight ones. Overweight/obese males and females showed lower EI from carbohydrates and fats, respectively, than their leaner counterparts.

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

    We present 2 cases of the slow-fast form of AVNRT with initially narrow QRS complexes followed by sudden unexpected transition to persistently wide QRS complexes due to aberrant intraventricular conduction. Introduction of a properly timed extrastimulus in one case and critical oscillations in cycle length due to short-long coupling in the second case set the stage for the initial bundle branch block. However, persistence of the aberrancy pattern once the initial event abated was maintained by the "linking" phenomenon. Delayed, retrograde concealed activation from the contralateral bundle branch perpetuated the initial bundle branch block. PMID:23840106

    Primary amoebic meningoencephalitis (PAM) is a rare and almost always fatal disease that is caused by Naegleria fowleri, a freshwater thermophilic amoeba. Our case involves an adolescent female who presented with fever of unknown origin. A lumbar puncture was performed, and the Wright-Giemsa and Gram stained cerebrospinal fluid (CSF) cytospin slides showed numerous organisms. Experienced medical technologists in the microbiology and hematology laboratories identified the organisms as morphologically consistent with Naegleria species. The laboratory made a rapid diagnosis and alerted emergency department care providers within 75 minutes. The patient was treated for PAM with amphotericin, rifampin, azithromycin, fluconazole and aggressive supportive therapy including dexamethasone.

    Primary amoebic meningoencephalitis (PAM) is a rare and almost always fatal disease that is caused by Naegleria fowleri, a freshwater thermophilic amoeba. Our case involves an adolescent female who presented with fever of unknown origin. A lumbar puncture was performed, and the Wright-Giemsa and Gram stained cerebrospinal fluid (CSF) cytospin slides showed numerous organisms. Experienced medical technologists in the microbiology and hematology laboratories identified the organisms as morphologically consistent with Naegleria species. The laboratory made a rapid diagnosis and alerted emergency department care providers within 75 minutes. The patient was treated for PAM with amphotericin, rifampin, azithromycin, fluconazole and aggressive supportive therapy including dexamethasone. The Centers for Disease Control and Prevention (CDC) was contacted, and miltefosine, an investigational medication, was started. Additional treatment included an intraventricular shunt and controlled hypothermia in order to mitigate potential cerebral edema. Our patient is a rare success story, as she was diagnosed swiftly, successfully treated, and survived PAM.

    An online survey of 3,461 North American girls ages 8-12 conducted in the summer of 2010 through Discovery Girls magazine examined the relationships between social well-being and young girls' media use--including video, video games, music listening, reading/homework, e-mailing/posting on social media sites, texting/instant messaging, and talking on phones/video chatting--and face-to-face communication. This study introduced both a more granular measure of media multitasking and a new comparative measure of media use versus time spent in face-to-face communication. Regression analyses indicated that negative social well-being was positively associated with levels of uses of media that are centrally about interpersonal interaction (e.g., phone, online communication) as well as uses of media that are not (e.g., video, music, and reading). Video use was particularly strongly associated with negative social well-being indicators. Media multitasking was also associated with negative social indicators. Conversely, face-to-face communication was strongly associated with positive social well-being. Cell phone ownership and having a television or computer in one's room had little direct association with children's socioemotional well-being. We hypothesize possible causes for these relationships, call for research designs to address causality, and outline possible implications of such findings for the social well-being of younger adolescents.

    Indonesia is currently facing the double burden of malnutrition. While undernutrition is still a major public health problem, the prevalence of overnutrition is increasing. The objective of the South East Asian Nutrition Survey (SEANUTS) was to provide up-to-date data on nutritional status, food consumption and biochemical parameters related to nutrition for children aged 0·5-12 years. The SEANUTS study in Indonesia was conducted in a nationwide representative sample of 7·211 children using multistage cluster sampling based on probability proportional to size, stratified for geographical location, in forty-eight out of 440 districts/cities. The results show that the growth (weight for age, height for age, weight for height and BMI for age) of Indonesian pre-school- and school-aged children is below the WHO standards. The older the children, the more the deviation from the WHO standard curves. Underweight was more prevalent in rural areas (28·9 v. 19·2%) and overweight/obesity was observed to be more widespread in urban areas (5·6 v. 3·2%). The prevalence varied with age groups and sexes. The overall prevalence of stunting was 25·2 and 39·2% in urban and rural areas, respectively. The prevalence of anaemia was nearly 55% in children aged 0·5-1·9 years and ranged from 10·6 to 15·5% in children aged 2-12 years. Fe deficiency was observed in 4·1-8·8% of the children. The percentage of children with dietary intakes of energy, protein, and vitamins A and C below the Indonesian RDA was high and differed across urban and rural areas and age groups.

    Full Text Available Objectives: Treating a carious tooth in children with high caries experience by providing a restoration does not cure the disease. If the unfavorable oral environment that caused the cavity persists so will the disease and more restorations will be required in future. Treating the oral infection by reducing the number of cariogenic microorganisms and establishing a favorable oral environment to promote predominantly remineralization of tooth structure over time will stop the caries process. The present study was conducted: (1 To evaluate the efficacy of povidone-iodine and chlorhexidine mouth rinses on plaque Streptococcus mutans when used as an adjunct to restoration. (2 To compare the anti-microbial effect of 1% povidone-iodine and 0.2% chlorhexidine mouth rinses on plaque S. mutans count. Study Design: Forty-five study participants in the age group of 6-12 years with dmft (decay component of three or four were selected from one government school in Bangalore city. They were divided into three groups after the restorative treatment. Group-A, Group-B, and Group-C received 1% povidone-iodine mouth rinse, 0.2% chlorhexidine mouth rinse and placebo mouth rinse, respectively, twice daily for 14 days. The plaque sample was collected and S. mutans count was estimated at six phases: (1 Baseline, (2 3 weeks after restoration, (3 First day after mouth rinse therapy, (4 15 days after mouth rinse therapy, (5 1 month and (6 3 months after mouth rinse therapy Results: After the restoration the percentage change in S. mutans count was 28.4%. Immediately after mouth rinse therapy there was significant reduction in S. mutans count in all the three groups. After which the count started to increase gradually and after 3 months the bacterial counts in the povidone-iodine group and placebo group were almost near the postrestorative count. Conclusion: Mouth rinses can be used as adjunct to restoration for short duration as temporary measure in reduction of S. mutans count and restorations provide longer effect. In case a mouth rinse has to be used, chlorhexidine can be recommended as it has shown to have better effect than Povidone-iodine and placebo.

    The aim of this study is to estimate the prevalence of spine and feet deformities among children who are regularly involved in basketball trainings, as well as finding differences in the prevalence of those deformities between children of different gender and age. The study included a total of 64 children, of which 43 were boys and 21 were girls, ages 10-12. All subjects have been regularly participating in basketball trainings for at least one year. Postural disorder is defined as an irregularity in posture of the spine and feet, and it is assessed by visual methods from the front, side and rear side of the body. The prevalence of spinal deformities in our group was 53.13%. The boys had a significantly higher prevalence than girls, 65.1% compared to 28.57% (p=0.006). There was no significant difference in prevalence of spine deformities between children of different ages. The prevalence of feet deformities was 64.06%. There was a statistically significant difference between the sexes, where boys had a significantly greater prevalence of the feet deformities than girls, 83.7% compared to 23.81% (p=0.001). Flat feet were the most common in 10 year old children (85.71%). In conclusion, it can be said that despite regular participation in basketball training, subjects in this study have high prevalence of deformities; especially boys who stand out with the high prevalence of flat feet.

  2. Passage-Based Bibliographic Coupling: An Inter-Article Similarity Measure for Biomedical Articles.

    Directory of Open Access Journals (Sweden)

    Rey-Long Liu

    Full Text Available Biomedical literature is an essential source of biomedical evidence. To translate the evidence for biomedicine study, researchers often need to carefully read multiple articles about specific biomedical issues. These articles thus need to be highly related to each other. They should share similar core contents, including research goals, methods, and findings. However, given an article r, it is challenging for search engines to retrieve highly related articles for r. In this paper, we present a technique PBC (Passage-based Bibliographic Coupling that estimates inter-article similarity by seamlessly integrating bibliographic coupling with the information collected from context passages around important out-link citations (references in each article. Empirical evaluation shows that PBC can significantly improve the retrieval of those articles that biomedical experts believe to be highly related to specific articles about gene-disease associations. PBC can thus be used to improve search engines in retrieving the highly related articles for any given article r, even when r is cited by very few (or even no articles. The contribution is essential for those researchers and text mining systems that aim at cross-validating the evidence about specific gene-disease associations.

    The Library of Babel, described by Jorge Luis Borges, stores an enormous amount of information. The Library exists ab aeterno. Wikipedia, a free online encyclopaedia, becomes a modern analogue of such a Library. Information retrieval and ranking of Wikipedia articles become the challenge of modern society. While PageRank highlights very well known nodes with many ingoing links, CheiRank highlights very communicative nodes with many outgoing links. In this way the ranking becomes two-dimensional. Using CheiRank and PageRank we analyze the properties of two-dimensional ranking of all Wikipedia English articles and show that it gives their reliable classification with rich and nontrivial features. Detailed studies are done for countries, universities, personalities, physicists, chess players, Dow-Jones companies and other categories.

    The current study explored subtle dehumanization-the denial of full humanness-in children, using distinctions of forms (i.e., animalistic vs. mechanistic) and social targets (i.e., friends vs. non-friends). In addition, the link between dehumanization and moral disengagement in bullying and victimization was investigated. Participants were 800 children (7-12 years old) from third to fifth grade classrooms. Subtle animalistic and mechanistic dehumanization toward friends and non-friends were measured with the new Juvenile Dehumanization Measure. Results showed that animalistic dehumanization was more common than mechanistic dehumanization and that non-friends were dehumanized more than friends. The highest levels of dehumanization were found in animalistic form toward non-friends and the lowest levels in mechanistic form toward friends. Both moral disengagement and animalistic dehumanization toward friends were positively associated with bullying. However, moral disengagement was negatively associated with victimization, whereas both animalistic and mechanistic dehumanization toward non-friends were positively associated with victimization. The current findings indicate that children are able to distinguish different forms and targets of dehumanization and that dehumanization plays a distinct role from moral disengagement in bullying and victimization.

    Knuth, Donald E

    2009-01-01

    The author presents two tricks to accelerate depth-first search algorithms for a class of combinatorial puzzle problems, such as tiling a tray by a fixed set of polyominoes. The first trick is to implement each assumption of the search with reversible local operations on doubly linked lists. By this trick, every step of the search affects the data incrementally. The second trick is to add a ghost square that represents the identity of each polyomino. Thus puts the rule that each polyomino be used once on the same footing as the rule that each square be covered once. The coding simplifies to a more abstract form which is equivalent to 0-1 integer programming. More significantly for the total computation time, the search can naturally switch between placing a fixed polyomino or covering a fixed square at different stages, according to a combined heuristic. Finally the author reports excellent performance for his algorithm for some familiar puzzles. These include tiling a hexagon by 19 hexiamonds and the N queen...

    Full Text Available Introduction & aims: The identification of determinants of childhood overweight is crucial to early diagnosis and prevention. The aim of this study was to assess perinatal and parental related risk factors concerning children for having excessive body weight. Methods: Cross-sectional study involving 3,101 children participating in the programme "Alimenta su salud" conducted in Castilla-La Mancha (Spain. Anthropometric and sociodemographic data were obtained from a general questionnaire. Analysed factors as potential predictors of childhood overweight were sex, age, birth weight, infant feeding, number of siblings, as well as parental marital status, educational level and obesity. Prevalence of overweight stratified by potential determinants was assessed. Univariate and multivariate logistic regression analyses were used to examine the associations between variables and the likelihood of being overweight. Results: The overweight prevalence (including obesity was 30.3% in boys and 28.3% in girls, according to the IOTF criteria. Higher rates in younger subjects and some gender differences were observed. Parental obesity was the most important predictive variable for childhood overweight in both sexes and birth weight over 3,500 g in girls (OR 1.8, 95% CI 1.3-2.3. Having one or more siblings (OR 0.7, 95% CI 0.5-0.9 and higher paternal education (OR 0.8, 95% CI 0.6-0.9 in boys, and older age in girls (OR 0.7, 95% CI 0.5-.09, resulted protective factors against childhood overweight. No independent effects of marital status, maternal education and infant feeding patterns on childhood excess weight were identified. Conclusions: Perinatal and parental factors could contribute to predict the risk of being overweight/obese in children aged 6 to 12 years, which should be considered when formulating obesity prevention and intervention strategies, stressing the importance of targeting obese parents with young children.Objetivos: Identificar los determinantes del sobrepeso infantil resulta clave para la prevención y diagnóstico precoz. El objetivo de este trabajo fue evaluar factores perinatales y paternos asociados al riesgo de sobrepeso y obesidad infantil. Métodos: Estudio transversal en 3.101 niños participantes en el programa "Alimenta su salud" llevado a cabo en Castilla-La Mancha. Los datos antropométricos y sociodemográficos fueron obtenidos mediante la aplicación de una encuesta. Las variables consideradas como potenciales predictores de sobrepeso infantil fueron sexo, edad, peso al nacer, lactancia recibida y número de hermanos de los niños, así como estado civil, nivel educativo y obesidad en los padres. El estudio analizó la frecuencia de sobrepeso estratificada por los potenciales factores de riesgo y se empleó regresión lineal univariante y multivariante para estudiar la asociación entre las variables candidatas y la probabilidad de tener sobrepeso. Resultados: La prevalencia de sobrecarga ponderal (incluyendo obesidad fue del 30,3% en los varones y el 28,3% en las niñas, de acuerdo con los criterios de IOTF. Los mayores porcentajes de exceso de peso se observaron en edades más tempranas con diferencias en función del sexo. La obesidad en los padres resultó el factor de riesgo más importante de sobrepeso y obesidad infantil en ambos sexos y en las chicas además, un peso al nacer mayor de 3.500 g (OR 1,8 IC 95% de 1,3-2,3. Por otro lado, tener uno o más hermanos (OR 0,7 IC 95% de 0,5-0,9 y un mayor nivel educativo paterno (OR 0,8 IC 95% de 0,6-0,9 resultaron factores protectores frente al sobrepeso infantil en chicos. La probabilidad de tener sobrepeso fue menor en las chicas de mayor edad (OR 0,7 IC 95% de 0,5 a 0,9. No se identificó un efecto independiente del estado civil, la educación materna o la lactancia recibida asociado al riesgo de sobrepeso infantil. Conclusiones: Ciertos factores perinatales y paternos pueden contribuir a predecir el riesgo de sobrepeso/obesidad en niños de 6 a 12 años, por lo que deberían ser considerados en el diseño de estrategias orientadas a la prevención e intervención precoz, haciendo hincapié en aquellas dirigidas a los padres obesos con niños pequeños.

    Full Text Available Abstract Bakckground The first aim was to examine the effect of the UP4FUN pilot intervention on children’s total sedentary time. The second aim was to investigate if the intervention had an effect on children’s physical activity (PA level. Finally, we aimed to investigate demographic differences (i.e. age, gender, ethnicity, living status and having siblings between children in the intervention group who improved in sedentary time and PA at post-test and children in the intervention group who worsened in sedentary time and PA at post-test. Methods The six weeks UP4FUN intervention was tested in a randomized controlled trial with pre-test post-test design with five intervention and five control schools in Belgium and included children of the 5th and 6th grade. The children wore accelerometers for seven days at pre- and post-test. Analyses included children with valid accelerometer data for at least two weekdays with minimum 10h-wearing time and one weekend day with 8h-wearing time. Result Final analyses included 372 children (60% girls, mean age = 10.9 ± 0.7 years. There were no significant differences in the change in sedentary time or light PA between intervention and control schools for the total sample or for the subgroup analyses by gender. However, children (specifically girls in the intervention group had a higher decrease in moderate-to-vigorous PA than children in the control group. In the intervention group, children who lived with both parents and children with one or more siblings were less likely to reduce sedentary time after exposure to the intervention. Older children, girls and children who lived with both parents were less likely to increase light PA after the intervention. Conclusion The UP4FUN intervention did not result in an effect on children’s sedentary time. Based on the high amounts of accelerometer-derived sedentary time in this age group, more efforts are needed to develop strategies to reduce children’s sedentary time.

Como objetivo secundario se pretende desarrollar una version reducida utilizable como instrumento de cribaje y, finalmente, analizar las propiedades psicométricas de ambos cuestionarios. El SCARED fue administrado a una muestra comunitaria de 1.508 niños de entre 8 y 12 años. Dicha muestra fue subdividida de forma aleatoria utilizando la primera mitad para el análisis exploratorio y la segunda para el confirmatorio. Además se desarrolló una versión reducida utilizando el procedimiento de Schmid-Leiman. El análisis factorial exploratorio reveló una estructura de 4 factores: Somático/pánico, Ansiedad generalizada, Ansiedad de separación y Fobia social. Esta estructura fue confirmada mediante al análisis factorial confirmatorio. Los cuatro factores, la escala completa y la escala reducida mostraron fiabilidades satisfactorias. Los resultados obtenidos parecen indicar que la version española del SCARED, al igual que algunos estudios recientes, presenta una estructura de cuatro factores relacionados que replican las dimensiones propuestas para los transtornos de ansiedad del DSM-IV-TR.

Setenta e oito crianças participaram do experimento em que foram manipulados os fatores idade, posição espacial, similaridade visual e cor dos estímulos memorizados. Os resultados mostraram que todos os fatores principais alcançaram significância estatística. As crianças mais velhas tiveram uma freqüência de acertos maior que as crianças mais novas. Os estímulos dos conjuntos com similaridade baixa foram mais bem recordados que os estímulos com similaridade alta. A taxa de recordação foi melhor nas provas em que as letras de um conjunto foram todas apresentadas com a mesma cor, assim como a porcentagem de respostas corretas variou de forma significativa em função da posição espacial dos estímulos. Os resultados foram interpretados de acordo com modelos que enfatizam aspectos do desenvolvimento de estratégias cognitivas ao longo do desenvolvimento humano, especialmente o modelo de memória de trabalho.This study aimed to evaluate the mechanisms of visual-spatial memory in children. Seventy eight children took part in an experiment with four factors: children's age, stimuli spatial position, stimuli visual similarity, stimuli set color. The results have shown that all main factors are statistically meaningful. The oldest children presented a better performance than the youngest ones. Stimuli set formed by low similarity letters were better recollected than the stimuli set formed by high similarity letters. The recall of the spatial position of letters was better in trials where the letters of a set were presented in the same color. The percentage of correct recall changed meaningfully as a function of the spatial position in which the target had been presented. The results were interpreted according to models that emphasize aspects of development of cognitive strategies along with the human development, especially the working memory model.

GOALS: To establish the prevalence of dysphonia in children, based on the opinion of the parents, acoustic and vocal-perceptual assessments, associated symptoms, risk factors and videolaryngoscopy findings. MATERIALS AND METHODS: The parents from 2,000 children answered a questionnaire about the vocal quality of their children, and these children were submitted to perceptual vocal, acoustic and videolaryngoscopy assessments. RESULTS: We had 1,007 boys and 993 girls; sporadic symptoms were reported by 206 parents and permanent symptoms were reported by 123. In the perceptual assessment, the G parameter (degree of dysphonia had a score of 0 in 694 voices; 1 in 1,065 and 2 in 228. There was f0 reduction with age and the remaining acoustic parameters were high in children with a G score of 2. Nodules, thickening and inflammation were the most common in the videolaryngoscopy exams. CONCLUSIONS: Parental judgment indicated a prevalence of dysphonia in 6.15%, and perceptual analysis yielded a value of 11.4%. Vocal symptoms were associated with a phonatory overload. sinonasal disorders, vocal abuse and noise were considered relevant risk factors. The acoustic analysis kept a direct association with the perceptual-auditory. Laryngeal lesions were found in the videolaryngoscopy exams, stressing nodules, thickening and inflammation.

    Full Text Available Objetivo. Identificar los factores de exposición asociados a las concentraciones de plomo en niños de escuelas primarias públicas y privadas de la ciudad de México. Material y métodos. Se realizó un estudio transversal en 340 niños que asistían a la escuela primaria. Las escuelas se seleccionaron por conveniencia y los niños en forma aleatoria. Se aplicó un cuestionario y se tomaron muestras de sangre venosa. Los niveles de plomo se determinaron por espectrofotometría de absorción atómica. Se compararon medias mediante la prueba t de Student-Fisher y ANDEVA; y para el análisis multivariado, regresión lineal múltiple. Debido a que los niveles de plomo no seguían una distribución normal, se transformó con logaritmo neperiano, con la que se trabajó en todo el análisis estadístico. Resultados. Las medias geométricas para escuelas privadas y públicas fueron: MG=8.76 µg/dl, IC95%=9.1-10.5; MG=11.5 µg/dl, IC95%=9.4-13.5, respectivamente. Los niveles de plomo son más elevados en los niños que asisten a la escuela pública y que presentan las siguientes características: ser varones, tener entre seis y ocho años de edad y cursar el primer o segundo grado de primaria; las madres de estos niños son profesionistas; en sus hogares se utiliza la cerámica vidriada y cerca de sus domicilios existen diferentes tipos de talleres contaminantes con plomo. Conclusiones. Los factores de exposición que predicen las concentraciones de plomo en sangre son: tener entre seis y ocho años de edad, la ocupación de la madre, la utilización de cerámica vidriada, la cercanía de diferentes tipos de talleres contaminantes con plomo a los domicilios y cursar el segundo año de primaria.Objective. To identify exposure factors contributing to lead poisoning in school children from Mexico City. Material and methods. Cross-sectional study of 340 children. A convenience sample of schools and a random sample of children were selected. A questionnaire was filled out and venous blood samples were taken. Lead levels were measured by atomic absorption spectrophotometry. Statistical analysis consisted of comparison of means using Student’s t test and ANOVA. Multiple linear regression was used for multivariate analysis. Logarithmic transformation of lead blood levels were used to account for their non-normal distribution. Results. Geometric means for private and public schools were: GM=8.76 µg/dl, 95% CI=9.1-10.5; GM=11.5 µg/dl, 95% CI=9.4-13.5. Lead levels were higher among children from public schools who are male, between 6 and 8 years of age, in first and second grade, whose mothers have a profession, who use glazed earthenware utensils, and who live near glazed earthenware shops or factories. Conclusions. Exposure predictors of lead blood levels are: being between 6 and 8 years of age, having a professional mother, using glazed earthenware utensils, living near glazed earthenware shops or factories, and studying the second grade of elementary school.

    Do you have a poor-performing employee on your medical practice team? If so, you're not alone. Unfortunately, this is a problem that many medical practice managers face. This article describes the best strategies for managing your team's weakest link. It explores common yet very difficult circumstances that cause low employee performance and that test the patience, heart, and skills of a practice manager. It guides readers through a process of self-discovery to determine whether their negative biases or grudges may be causing employees to perform poorly. It suggests several possible other reasons for weak employee performance, including problems with the job, practice, leadership, communication, and fit between the employee and the job. This article also suggests the best strategy for communicating concerns about performance to the weakest-link employee. It offers guidance to practice managers about protecting their time and energy when handling a poor performer. It provides a simple formula for calculating the cost of a low-performing employee, 10 possible personal reasons for the employee's poor work performance, specific questions to ask to uncover the reasons for poor performance, and an eight-rule strategy for confronting poor performance effectively. Finally, this article offers practice managers a practical strategy for handling resistance from their weakest link, illustrated with a sample dialogue.

    Statistics of article page views is useful for measuring the impact of individual articles. Analyzing the temporal evolution of article page views, we find that article page views usually decay over time after reaching a peak, especially exhibiting relaxation with nonexponentiality. This finding suggests that relaxation in article page views resembles physical aging as frequently found in complex systems.

  12. Finding and Recommending Scholarly Articles

    Science.gov (United States)

    Kurtz, Michael J.; Henneken, Edwin A.

    2014-05-01

    The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change. Just like everybody else involved in information discovery, scholars are confronted with information overload. Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

    The Appreciation of RMB, the Behavior of Firms and the Export Trade: A Case Study Based on the Enterprise Data of a Large Specimen between 2005 and 2009 In this article, we have constructed a simplified dynamic discrete choice model to analyze, within the framework of the maximization of profit, the two-stage decision of firm' s export behavior and the effect of the exchange rate. We have, by the means of the specimen data on China' s industrial enterprises between 2005 and 2009 and by the use of Heckman selection model, evaluated the general impact of the appreciation of RMB (AORMB) on the export trade and the structural impact. The results of our study indicate that the AORMB has generated significant negative shock to firm ' s export through extensive margins and intensive margins. Meanwhile, the difference in operation strategy of heteroge- neous firms has resulted in the fact that the AORMB can hardly achieve the expected purpose of the survival of the fit- test; instead it has interrupted the optimization of the adjustment in the optimization of the structure of the main body of the export trade. The AORMB has, in a certain degree, driven the industry structure of export to develop to a higher phase. However, such positive effects have mainly rooted in the contribution of foreign-funded enterprises, but this pos- itive role has restricted the growth space of the local enterprises in the advanced manufacturing industry. Under the cir- cumstance of high uncertainty in foreign and domestic economy, in order to guarantee the steady transition of the eco- nomic transition, the AORMB should be slowed for the time being, and other more pertinent measures should be adopt- ed to drive the upgrade of the export trade and the adjustment of economic structure.

I can scan the table of contents to find articles I want to read, or I can just browse through the issue to see what looks interesting. Usually the editors have juxtaposed related articles so that I often find a small treasure trove. The printed Journal is quite portable and can be read in a car or airplane. It will last a long time, and until the paper deteriorates, I will never have a problem reading back issues. I have almost every issue from the first day I subscribed and have even added some older ones from collections of retired colleagues who no longer had shelf space for them. I certainly would not want to give up my printed copies, and I want to keep getting them. I find that JCE Online provides a different kind of resource that is equally valuable. It contains more information, and information that is more appropriate in electronic form. It links related ideas into a much more complex web of information than is possible in print. And it opens pathways to lots of information that is not part of JCE but resides elsewhere. Using this issue as an example, let's take a tour of what JCE Online can do. Point your Web browser to http://jchemed.chem.wisc.edu Click on Journal and then on Current Issue (unless September 1999 is no longer the current issue, in which case you will find it in Past Issues).

IS is a type of seizure that was first described by West in 1841, who witnessed the seizure in his own son. West’s syndrome refers to the classic triad of spasms, characteristic EEG, and neurodevelopmental regression. Most cases involve flexors and extensors,but either of the types may be involved independently.IS, as its name implies, most often occurs during the first year of life with an incidence of approximately 1 per 2000-4000 live births. Most, but not all, patients with this disorder have severe EEG abnormalities; this pattern was originallyreferred to as hypsarrhythmia by Gibbs and Gibbs. Cases with known etiology or signs of brain damage are considered as symptomatic. The Overall prognosis of the disease is poor. Peak onset age of the epileptic syndrome is 3 to 7 months, which mainly occurs before 2 years of age in 93% of patients. Hypsarrhythmia is the EEG hallmark of IS, which comprised a chaotic, bilaterally asynchronous high-voltage polyspike, and slow wave discharges interspersed with multifocal spikes and slow waves.Etiological classification is as follows: 1 Symptomatic: with identifiable prenatal, perinatal, and postnatal causes with developmental delay at the presentation time; 2 Cryptogenic: unknown underlying cause, normal development at the onset of spasms, normal neurological exam and neuroimaging, and no abnormality in the metabolic evaluation; 3 Idiopathic: pure functional cerebral dysfunction with complete recovery, no residual dysfunction, normal neuroimaging and normal etiologic evaluation, and normal neurodevelopment.ReferencesInfantile Spasms.

  17. Toward an interactive article: integrating journals and biological databases

    2011-05-01

    Full Text Available Abstract Background Journal articles and databases are two major modes of communication in the biological sciences, and thus integrating these critical resources is of urgent importance to increase the pace of discovery. Projects focused on bridging the gap between journals and databases have been on the rise over the last five years and have resulted in the development of automated tools that can recognize entities within a document and link those entities to a relevant database. Unfortunately, automated tools cannot resolve ambiguities that arise from one term being used to signify entities that are quite distinct from one another. Instead, resolving these ambiguities requires some manual oversight. Finding the right balance between the speed and portability of automation and the accuracy and flexibility of manual effort is a crucial goal to making text markup a successful venture. Results We have established a journal article mark-up pipeline that links GENETICS journal articles and the model organism database (MOD WormBase. This pipeline uses a lexicon built with entities from the database as a first step. The entity markup pipeline results in links from over nine classes of objects including genes, proteins, alleles, phenotypes and anatomical terms. New entities and ambiguities are discovered and resolved by a database curator through a manual quality control (QC step, along with help from authors via a web form that is provided to them by the journal. New entities discovered through this pipeline are immediately sent to an appropriate curator at the database. Ambiguous entities that do not automatically resolve to one link are resolved by hand ensuring an accurate link. This pipeline has been extended to other databases, namely Saccharomyces Genome Database (SGD and FlyBase, and has been implemented in marking up a paper with links to multiple databases. Conclusions Our semi-automated pipeline hyperlinks articles published in GENETICS to

  4. Challenges and Usage of Link Mining to Semantic Web

    Zaved Akhtar

    2012-03-01

    Full Text Available - It is an emerging challenge for data mining is the problem of mining richly structures datasets, where the objects are linked in some way. Links among the objects may demonstrate certain patterns, which can be helpful for many data mining tasks and are usually hard to capture with traditional statistical models. Many datasets of interest today are best described as a linked collection of interrelated objects. These may represent homogeneous networks, in which there is a single-object type and link type (eg. people connected by friendship links, or the WWW, a collection of linked web pages or richer, heterogeneous networks, in which there may be multiple object and link types (and possibly other semantic information. Examples of heterogeneous networks include those in medical domains describing patients, diseases, treatments and contacts, or in bibliographic domains describing publications, authors, and venues. Link mining refers to data mining techniques that explicitly consider these links when building predictive or descriptive models of the linked data. Commonly addressed link mining tasks include object ranking, group detection, collective classification, link prediction and subgraph discovery. This is an exciting and rapidly expanding area. In this article we review some of the common emerging themes and discuss ongoing link mining challenges; open issues and suggest ideas that could be opportunities for solutions. The most conclusion of this article is that providing an idea to usage link mining techniques from link mining to help to construct the Semantic Web.

    Full Text Available Keratoconus is a common ectatic disorder occurring in more than 1 in 1,000 individuals. The condition typically starts in adolescence and early adulthood. It is a disease with an uncertain cause and its progression is unpredictable, but in extreme cases, vision deteriorates and can require corneal transplant surgery. Corneal collagen cross-linking (CCL with riboflavin (C3R is a recent treatment option that can enhance the rigidity of the cornea and prevent disease progression. Since its inception, the procedure has evolved with newer instrumentation, surgical techniques, and is also now performed for expanded indications other than keratoconus. With increasing experience, newer guidelines regarding optimization of patient selection, the spectrum of complications and their management, and combination procedures are being described. This article in conjunction with the others in this issue, will try and explore the uses of collagen cross-linking (CXL in its current form.

  6. A novel missense mutation in the CLCN7 gene linked to benign autosomal dominant osteopetrosis: a case series

    2013-01-01

    Full Text Available Abstract Introduction Osteopetrosis is a rare inherited genetic disease characterized by sclerosis of the skeleton. The absence or malfunction of osteoclasts is found to be strongly associated with the disease evolution. Currently, four clinically distinct forms of the disease have been recognized: the infantile autosomal recessive osteopetrosis, the malignant and the intermediate forms, and autosomal dominant osteopetrosis, type I and type II forms. The autosomal recessive types are the most severe forms with symptoms in very early childhood, whereas the autosomal dominant classes exhibit a heterogeneous trait with milder symptoms, often at later childhood or adulthood. Case presentation Case 1 is the 12-year-old daughter (index patient of an Iraqi-Kurdish family who, at the age of eight years, was diagnosed clinically to have mild autosomal dominant osteopetrosis. Presently, at 12-years old, she has severe complications due to the disease progression. In addition, the same family previously experienced the death of a female child in her late childhood. The deceased child had been misdiagnosed, at that time, with thalassemia major. In this report, we extended our investigation to identify the type of the inheritance patterns of osteopetrosis using molecular techniques, because consanguineous marriages exist within the family history. We have detected one heterozygous mutation in exon 15 of the Chloride Channel 7 gene in the index patient (Case 1, whereas other mutations were not detected in the associated genes TCIRG1, OSTM1, RANK, and RANKL. The missense mutation (CGG>TGG located in exon 15 (c.1225C>T of the Chloride Channel 7 gene changed the amino acid position 409 from arginine to tryptophan (p.R409W, c.1225C>T. Case 2 is the 16-year-old son (brother of the index patient of the same family who was diagnosed clinically with mild autosomal dominant osteopetrosis. We have identified the same heterozygous mutation in exon 15 of the Chloride

    Link prediction in complex networks has attracted increasing attention from both physical and computer science communities. The algorithms can be used to extract missing information, identify spurious interactions, evaluate network evolving mechanisms, and so on. This article summaries recent progress about link prediction algorithms, emphasizing on the contributions from physical perspectives and approaches, such as the random-walk-based methods and the maximum likelihood methods. We also introduce three typical applications: reconstruction of networks, evaluation of network evolving mechanism and classification of partially labeled networks. Finally, we introduce some applications and outline future challenges of link prediction algorithms.

    2016-01-01

    Full Text Available This paper mainly focuses on estimating the relatedness and similarities between any two Wikipedia [1] articles. This paper describes various ways of determining the similarities. We hypothesize that by using some kind of properties of the Wikipedia articles, which can be internal or external, we can estimate the relatedness between Wikipedia articles. Each article is believed to have some kinds of internal properties and some external properties. Internal properties are those which are embedded inside the articles. It can be, for instance, have something to do with the content and text of the articles. External properties are those which are deduced or inferred from the articles. It can be, for example, the topic of the articles or even the closest distance between the two articles when plotted in a graph or in a category hierarchy.External properties include the properties associated with individual articles like topics (as mentioned,categories of the articles. Other techniques which are relevant when comparing the Wikipedia articles are cosine similarity, Jaccard similarity measure etc

  1. Measuring the Interestingness of News Articles

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

    Full Text Available Most of the scientific work presented as abstracts (platforms and posters at various conferences have the potential to be published as articles in peer-reviewed journals. This DIY (Do It Yourself article on how to achieve that goal is an extension of the symposium presented at the 36 th European Congress of Cytology, Istanbul, Turkey (presentation available on net at http://alturl.com/q6bfp. The criteria for manuscript authorship should be based on the ICMJE (International Committee of Medical Journal Editors Uniform Requirements for Manuscripts. The next step is to choose the appropriate journal to submit the manuscript and review the ′Instructions to the authors′ for that journal. Although initially it may appear to be an insurmountable task, diligent organizational discipline with a little patience and perseverance with input from mentors should lead to the preparation of a nearly perfect publishable manuscript even by a novice. Ultimately, the published article is an excellent track record of academic productivity with contribution to the general public good by encouraging the exchange of experience and innovation. It is a highly rewarding conduit to the personal success and growth leading to the collective achievement of continued scientific progress. Recent emergences of journals and publishers offering the platform and opportunity to publish under an open access charter provides the opportunity for authors to protect their copyright from being lost to conventional publishers. Publishing your work on this open platform is the most rewarding mission and is the recommended option in the current modern era.

  3. Enzyme-linked acute oxygen sensing in airway and arterial chemoreceptors--invited article.

    Science.gov (United States)

    Kemp, J Paul; Peers, C

    2009-01-01

    Researchers have speculated as to the molecular basis of O(2) sensing for decades. In more recent years, since the discovery of ion channels as identified effectors for O(2) sensing pathways, research has focussed on possible pathways coupling a reduction in hypoxia to altered ion channel activity. The most extensively studied systems are the K(+) channels which are inhibited by hypoxia in chemoreceptor tissues (carotid and neuroepithelial bodies). In this review, we consider the evidence supporting the involvement of well defined enzymes in mediating the regulation of K(+) channels by hypoxia. Specifically, we focus on the roles proposed for three enzyme systems; NADPH oxidase, heme oxygenase and AMP activated protein kinase. These systems differ in that the former two utilise O(2) directly (to form superoxide in the case of NADPH oxidase, and as a co-factor in the degradation of heme to carbon monoxide, bilirubin and ferrous iron in the case of heme oxygenase), but the third responds to shifts in the AMP:ATP ratio, so responds to changes in O(2) levels more indirectly. We consider the evidence in favour of each of these systems, and highlight their differential importance in different systems and species. Whilst the evidence for each playing an important role in different tissues is strong, there is a clear need for further study, and current awareness indicates that no one specific cell type may rely on a single mechanism for O(2) sensing.

  7. Links and Quantum Entanglement

    CERN Document Server

    Solomon, A I

    2011-01-01

    We discuss the analogy between topological entanglement and quantum entanglement, particularly for tripartite quantum systems. We illustrate our approach by first discussing two clearly (topologically) inequivalent systems of three-ring links: The Borromean rings, in which the removal of any one link leaves the remaining two non-linked (or, by analogy, non-entangled); and an inequivalent system (which we call the NUS link) for which the removal of any one link leaves the remaining two linked (or, entangled in our analogy). We introduce unitary representations for the appropriate Braid Group ($B_3$) which produce the related quantum entangled systems. We finally remark that these two quantum systems, which clearly possess inequivalent entanglement properties, are locally unitarily equivalent.

    2013-06-01

    Full Text Available The topic of innovation as a source of competitive advantage for firms is consolidated in the literature. An innovation-based advantage is generally achieved by following a structured process, in which technological capability plays a key role. However, a question remains in studies into innovation, which is concerned with the reasons why not all firms that develop a technological capability are innovative. Where is the missing link? Great efforts have been made in attempts to answer to this question. However, the study of this link as a source of advantage for firms deserves further attention. This article aims to present a framework with two essential dimensions: (1 the technological capability and (2 the transactional capability. Technological capability is the ability of firms to make effective use of technical knowledge in order to improve production processes and develop new products and services. Transactional capability is defined as a repertoire of abilities, processes, experiences, skills, knowledge and routines that the firm uses to minimize its transaction costs (ex¿ante and ex¿post. Given that the present study is a theoretical paper, methodologically it is based on a literature review. The main finding of this study is the identification of transactional capability as the missing link in innovation. Accordingly, to be innovative, in addition to having a technological capability, a firm needs to develop its transactional capability.

    2015-01-01

    Full Text Available Popular science magazines cover research articles published in scholarly journals that the magazines perceive as having news value. Despite thousands of research articles being published in research journals, a very few get identified for coverage in popular science magazines, general magazines, and newspapers. Do research articles published in journals that are covered in popular science magazines receive higher citations? We hypothesize that newsworthy articles should receive higher citations as the newsworthiness can be a reflection of higher research value of the articles and also because of the visibility received by the articles owing to its coverage in popular science magazine. To empirically study the citedness, we identified 193 research articles and that were reported in New Scientist magazine in 2001. The characteristics of these articles including the citations received following coverage in New Scientist in 2001 were looked at. It was found that average citations per paper of articles covered in New Scientist was higher than the journal average for the year 2001 for 19 out of the 24 journals identified here.

    2012-03-01

    Full Text Available Abstract Background Rapid identification of subject experts for medical topics helps in improving the implementation of discoveries by speeding the time to market drugs and aiding in clinical trial recruitment, etc. Identifying such people who influence opinion through social network analysis is gaining prominence. In this work, we explore how to combine named entity recognition from unstructured news articles with social network analysis to discover opinion leaders for a given medical topic. Methods We employed a Conditional Random Field algorithm to extract three categories of entities from health-related new articles: Person, Organization and Location. We used the latter two to disambiguate polysemy and synonymy for the person names, used simple rules to identify the subject experts, and then applied social network analysis techniques to discover the opinion leaders among them based on their media presence. A network was created by linking each pair of subject experts who are mentioned together in an article. The social network analysis metrics (including centrality metrics such as Betweenness, Closeness, Degree and Eigenvector are used for ranking the subject experts based on their power in information flow. Results We extracted 734,204 person mentions from 147,528 news articles related to obesity from January 1, 2007 through July 22, 2010. Of these, 147,879 mentions have been marked as subject experts. The F-score of extracting person names is 88.5%. More than 80% of the subject experts who rank among top 20 in at least one of the metrics could be considered as opinion leaders in obesity. Conclusion The analysis of the network of subject experts with media presence revealed that an opinion leader might have fewer mentions in the news articles, but a high network centrality measure and vice-versa. Betweenness, Closeness and Degree centrality measures were shown to supplement frequency counts in the task of finding subject experts. Further

    Full Text Available Open access (OA to the research literature has the potential to accelerate recognition and dissemination of research findings, but its actual effects are controversial. This was a longitudinal bibliometric analysis of a cohort of OA and non-OA articles published between June 8, 2004, and December 20, 2004, in the same journal (PNAS: Proceedings of the National Academy of Sciences. Article characteristics were extracted, and citation data were compared between the two groups at three different points in time: at "quasi-baseline" (December 2004, 0-6 mo after publication, in April 2005 (4-10 mo after publication, and in October 2005 (10-16 mo after publication. Potentially confounding variables, including number of authors, authors' lifetime publication count and impact, submission track, country of corresponding author, funding organization, and discipline, were adjusted for in logistic and linear multiple regression models. A total of 1,492 original research articles were analyzed: 212 (14.2% of all articles were OA articles paid by the author, and 1,280 (85.8% were non-OA articles. In April 2005 (mean 206 d after publication, 627 (49.0% of the non-OA articles versus 78 (36.8% of the OA articles were not cited (relative risk = 1.3 [95% Confidence Interval: 1.1-1.6]; p = 0.001. 6 mo later (mean 288 d after publication, non-OA articles were still more likely to be uncited (non-OA: 172 [13.6%], OA: 11 [5.2%]; relative risk = 2.6 [1.4-4.7]; p < 0.001. The average number of citations of OA articles was higher compared to non-OA articles (April 2005: 1.5 [SD = 2.5] versus 1.2 [SD = 2.0]; Z = 3.123; p = 0.002; October 2005: 6.4 [SD = 10.4] versus 4.5 [SD = 4.9]; Z = 4.058; p < 0.001. In a logistic regression model, controlling for potential confounders, OA articles compared to non-OA articles remained twice as likely to be cited (odds ratio = 2.1 [1.5-2.9] in the first 4-10 mo after publication (April 2005, with the odds ratio increasing to 2.9 (1

  8. Citing Journal Articles in Social Sciences Blogs

    Full Text Available This article aims to analyze motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations of scholarly journal articles are good indicators for the societal impact of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging published between 01/01/2012 to 18/06/2014 were subjected to content analysis. An existing categorization scheme was used and modified inductively. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty-one (22.68% of all journals cited were from the category of social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy-five percent of all journals were referenced only once. The average age of articles cited was 5.8 years. The most frequent (38, 12.67% motivation was to ‘neutrally presenting details of a study’. Overall, social science blogs were rather subject-oriented than article oriented. This means a considerable number of blog posts were not driven simply by writing about an article, instead bloggers tend to write about their subject of interest and use references to support their argument. The study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact.

  9. Production of super-smooth articles

    Energy Technology Data Exchange (ETDEWEB)

    Duchane, D.V.

    1981-05-29

    Super-smooth rounded or formed articles made of thermoplastic materials including various poly(methyl methacrylate) or acrylonitrile-butadiene-styrene copolymers are produced by immersing the articles into a bath, the composition of which is slowly changed with time. The starting composition of the bath is made up of at least one solvent for the polymer and a diluent made up of at least one nonsolvent for the polymer and optional materials which are soluble in the bath. The resulting extremely smooth articles are useful as mandrels for laser fusion and should be useful for a wide variety of other purposes, for example lenses.

  11. Linking to Data - Effect on Citation Rates in Astronomy

    CERN Document Server

    Henneken, Edwin A

    2011-01-01

    Is there a difference in citation rates between articles that were published with links to data and articles that were not? Besides being interesting from a purely academic point of view, this question is also highly relevant for the process of furthering science. Data sharing not only helps the process of verification of claims, but also the discovery of new findings in archival data. However, linking to data still is a far cry away from being a "practice", especially where it comes to authors providing these links during the writing and submission process. You need to have both a willingness and a publication mechanism in order to create such a practice. Showing that articles with links to data get higher citation rates might increase the willingness of scientists to take the extra steps of linking data sources to their publications. In this presentation we will show this is indeed the case: articles with links to data result in higher citation rates than articles without such links. The ADS is funded by NA...

  12. Dynamical fat link fermions

    2004-01-01

    The use of APE smearing or other blocking techniques in fermion actions can provide many advantages. There are many variants of these fat link actions in lattice QCD currently, such as FLIC fermions. Frequently, fat link actions make use of the APE blocking technique in combination with a projection of the blocked links back into the special unitary group. This reunitarisation is often performed using an iterative maximisation of a gauge invariant measure. This technique is not differentiable with respect to the gauge field and thus prevents the use of standard Hybrid Monte Carlo simulation algorithms. The use of an alternative projection technique circumvents this difficulty and allows the simulation of dynamical fat link fermions with standard HMC and its variants.

  3. Tracking Multiple Topics for Finding Interesting Articles

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K; Cardenas, A F; Buttler, D J; Critchlow, T J

    2007-02-15

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

    Full Text Available Background: Scientific publications within Medical Sciences are an important factor for professionals to achieve services of excellence. However, the training to write this kind of articles is not enough. Objective: To design a theoretical and practical course of composition and style for scientific articles publications. Methods: Observational, descriptive, cross-sectional study including 50 professionals of the Medical School Branch. The main difficulties that they face to publish an article were determined and a distance learning course was designed on this basis, using the Moodle platform. Results: All the surveyed individuals referred that among the main causes limiting their ability to publish scientific articles are: little practical knowledge about the requirements to write scientific articles, not receiving any subject enhancing textual composition during their academic formation, and not attending to any post-graduate course aimed at improving academic writing for publication. A curse of 10 hours (theoretical part and 30 hours (practical part divide into five chapters including stylistic, methodological and compositional elements. Conclusions: This course helps improving the composition of scientific articles written by professional and their further publication in scientific journals.

    "Linked Data" is a term used in Computer Science to encapsulate a methodology for publishing data and metadata in a structured format so that links may be created and exploited between objects. Berners-Lee (2006) outlines the following four design principles of a Linked Data system: Use Uniform Resource Identifiers (URIs) as names for things. Use HyperText Transfer Protocol (HTTP) URIs so that people can look up those names. When someone looks up a URI, provide useful information, using the standards (Resource Description Framework [RDF] and the RDF query language [SPARQL]). Include links to other URIs so that they can discover more things. In 2010, Berners-Lee revisited his original design plan for Linked Data to encourage data owners along a path to "good Linked Data". This revision involved the creation of a five star rating system for Linked Data outlined below. One star: Available on the web (in any format). Two stars: Available as machine-readable structured data (e.g. An Excel spreadsheet instead of an image scan of a table). Three stars: As two stars plus the use of a non-proprietary format (e.g. Comma Separated Values instead of Excel). Four stars: As three stars plus the use of open standards from the World Wide Web Commission (W3C) (i.e. RDF and SPARQL) to identify things, so that people can point to your data and metadata. Five stars: All the above plus link your data to other people's data to provide context Here we present work building on the SeaDataNet common vocabularies served by the NERC Vocabulary Server, connecting projects such as the Rolling Deck to Repository (R2R) and the Biological and Chemical Oceanography Data Management Office (BCO-DMO) and other vocabularies such as the Marine Metadata Interoperability Ontology Register and Repository and the NASA Global Change Master Directory to create a Linked Ocean Data cloud. Publishing the vocabularies and metadata in standard RDF XML and exposing SPARQL endpoints renders them five-star Linked

    Corral de la Calle, M A; Encinas de la Iglesia, J

    2013-06-01

    Scientific research and the publication of the results of the studies go hand in hand. Exquisite research methods can only be adequately reflected in formal publication with the optimum structure. To ensure the success of this process, it is necessary to follow orderly steps, including selecting the journal in which to publish and following the instructions to authors strictly as well as the guidelines elaborated by diverse societies of editors and other institutions. It is also necessary to structure the contents of the article in a logical and attractive way and to use an accurate, clear, and concise style of language. Although not all the authors are directly involved in the actual writing, elaborating a scientific article is a collective undertaking that does not finish until the article is published. This article provides practical advice about formal and not-so-formal details to take into account when writing a scientific article as well as references that will help readers find more information in greater detail.

    CERN Document Server

    Feng, Feng

    2012-01-01

    FORM, a symbolic manipulation system, has been widely used in a lot of calculations for High Energy Physics due to its high performance and fficient design. Mathematica, another computational software program, has also widely been used, but more for reasons of generality and user-friendliness than for speed. Especially calculations involving tensors and noncommutative operations like calculating Dirac traces can be rather slow in Mathematica, compared to FORM. In this article we describe FormLink and FeynCalcFormLink, two Mathematica packages to link Mathematica and FeynCalc with FORM. FormLink can be used without FeynCalc and FeynCalcFormLink, which is an extension loading FormLink and FeynCalc automatically. With these two packages the impressive speed and other special features of FORM get embedded into the generality of Mathematica and FeynCalc in a simple manner. FeynCalcFormLink provides a FORM-based turbo for FeynCalc, making it much more efficient. FormLink turns Mathematica into an editor and code or...

    Directory of Open Access Journals (Sweden)

    T. N. Van der Linde

    2006-12-01

    Full Text Available Purpose: Shared services is a viable business model that can be used by organisations to reduce costs and enhance efficiency and effectiveness in the organisation. The purpose of this trilogy of articles is to introduce shared services as a business model, and how to efficiently and effectively manage a shared services business unit. The purpose of the first article in the trilogy, introduces shared services as a business model, defines what shared services is, the transformation required to successfully implement a shared services business model, as well as the benefits that can be derived from implementing a shared services business model. Methodology: A comprehensive literature study was conducted in order to: - Define and describe shared services as a business model, - Compare shared services with centralisation and de-centralisation, - Determine and describe the transformation required to successfully implement shared services. Findings: In the article, a framework is generated to help organisations understand the business concept of shared services. This work has further potential: when applied correctly, there are both tangible and intangible benefits that can be accrued above cost savings. Implications: The findings of this article are important for organisations that are in the process of implementing or have implemented shared services, as it will assist the organisation in determining if shared services is the correct business model for them to implement. Value: This article provides an understanding of shared services and the business environment required to successfully implement a shared services business model. Value created by a shared services business model is further enhanced once the organisation has embarked on the successful implementation of a shared services business model, which is the primary objective of the second article, Implementation and continuous evolution in shared services.

    Introduction Altmetrics is a new and emerging scholarly tool that measures online attention surrounding journal articles. Altmetric data resources include: policy documents, news outlets, blogs, online reference managers (eg Mendeley and CiteULike), post-publication peer-review forums (eg PubPeer and Publons), social media (eg Twitter, Facebook, Weibo, Google(+), Pinterest, Reddit), Wikipedia, sites running Stack Exchange (Q&A), and reviews on F1000 and YouTube.Methods To identify the top 50 dental articles in 2014, PubMed was searched using the following query "("2014/1/1"[PDAT]:"2014/12/31"[PDAT]) and jsubsetd[text]" in December, 2015. Consequently, all PubMed records were extracted and sent to Altmetric LLP (London, UK) as a CSV file for examination. Data were analysed by Microsoft Office Excel 2010 using descriptive statistics and charts.Results Using PubMed searches,15,132 dental articles were found in 2014. The mean Altmetric score of 50 top dental articles in 2014 was 69.5 ± 73.3 (95% CI: -74.14 to 213.14). The British Dental Journal (48%) and Journal of Dental Research (16%) had the maximum number of top articles. Twitter (67.13%), Mendeley (15.89%) and news outlets (10.92%) were the most popular altmetric data resources.Discussion Altmetrics are intended to supplement bibliometrics, not replace them. Altmetrics is a fresh and emerging arena for the dental research community. We believe that dental clinical practitioners, research scientists, research directors and journal editors must pay more attention to altmetrics as a new and rapid tool to measure the social impact of scholarly articles.

    The Library of Babel, described by Jorge Luis Borges, stores an enormous amount of information. The Library exists {\\it ab aeterno}. Wikipedia, a free online encyclopaedia, becomes a modern analogue of such a Library. Information retrieval and ranking of Wikipedia articles become the challenge of modern society. We analyze the properties of two-dimensional ranking of all Wikipedia English articles and show that it gives their reliable classification with rich and nontrivial features. Detailed studies are done for countries, universities, personalities, physicists, chess players, Dow-Jones companies and other categories.

  19. How Elsevier's Article of the Future supports researchers in the digital era

    Science.gov (United States)

    Keall, B.

    2012-04-01

    The first phase of Elsevier's Article of the Future article format was released on SciVerse ScienceDirect in January 2012. While this new format for online scholarly articles brings a significantly improved online presentation, it also enables further enhancements in terms of domain-specific content and contextualization of research results. Of particular interest to the Earth Sciences research community are the seamless integration of an interactive map viewer that displays author-submitted KML files inside the article, and real-time links to leading research data portals like Pangaea and Earthchem. These enhancements allow for a richer form of communication between authors and readers, and present researchers with valuable additional information in the context of the article. In this presentaion I will review these ongoing efforts to enhance online articles in the digital era.

    Mikolajczak, Gladys; Desseilles, Martin

    2012-01-01

    Music is an important part of young people's lives. In this article, we attempt to answer two questions on the links between music et suicide. First, we examine if certain types of music favor suicidal process (ideation and acting out); and, secondly, we examine if music can constitute a tool to reduce the risk of suicide. Several factors possibly involved in links between musical preferences and the suicidal process are developed: the Velten effect and the musical mood induction procedure, the identification and the learning by imitation, the media influence as well as the individual characteristics. A multifactor approach is necessary to understand the complex and birectional links that unite musical preferences and suicide risk. PMID:23666285

  15. Helically linked mirror arrangement

    International Nuclear Information System (INIS)

    A scheme is described for helical linking of mirror sections, which endeavors to combine the better features of toroidal and mirror devices by eliminating the longitudinal loss of mirror machines, having moderately high average β and steady state operation. This scheme is aimed at a device, with closed magnetic surfaces having rotational transform for equilibrium, one or more axisymmetric straight sections for reduced radial loss, a simple geometrical axis for the links and an overall positive magnetic well depth for stability. We start by describing several other attempts at linking of mirror sections, made both in the past and the present. Then a description of our helically linked mirror scheme is given. This example has three identical straight sections connected by three sections having helical geometric axes. A theoretical analysis of the magnetic field and single-particle orbits in them leads to the conclusion that most of the passing particles would be confined in the device and they would have orbits independent of pitch angle under certain conditions. Numerical results are presented, which agree well with the theoretical results as far as passing particle orbits are concerned

    If we examine the text of scientific articles it is clear that there is a generally accepted way of writing them. Scientific prose in English stereotypically uses the third person, the passive tense, complex terminology, and various footnoting and referencing systems. Scientific prose is not known for discursive anecdotes, humour, pictures, colour, bizarre typography or exclamation marks! Often the written text appears quite impersonal-the human element is removed.

    Objective: To investigate the distribution of academic conflicts, if any, in medical research articles. Methods: Twenty-seven and 25 medical research articles in the field of internal medicine were selected from English and Chinese respectable jour⁃nals, respectively. Then, the speech acts that reflected a conflict between a scientist’s knowledge claim and another scientist’s knowledge claim were manually searched and recorded in each paper. Data were analyzed using non-parametric Chi-test. Results:There were 123 academic conflicts recorded in the English corpus and 49 Academic Conflicts in the Chinese corpus. Significant difference was observed in the overall frequency of academic conflicts between the English and Chinese medical discourse (p=0.001). Besides, as for the distribution within research articles, introduction and discussion sections were the sections where Aca⁃demic Conflict speech acts were most likely to occur in both corpra. Conclusion: The Chinese scholars are less likely to criticize peers. Introduction and discussion sections were the sections where Academic Conflict speech acts were most likely to occur. Our results are in agreement with previous results and confirmed the claim that highly different cultures vary in their discourse prefer⁃ences. Our findings are of pedagogical significance.

  6. Volumes of chain links

    CERN Document Server

    Kaiser, James; Rollins, Clint

    2011-01-01

    Agol has conjectured that minimally twisted n-chain links are the smallest volume hyperbolic manifolds with n cusps, for n at most 10. In his thesis, Venzke mentions that these cannot be smallest volume for n at least 11, but does not provide a proof. In this paper, we give a proof of Venzke's statement. The proof for n at least 60 is completely rigorous. The proof for n between 11 and 59 uses a computer calculation, and can be made rigorous for manifolds of small enough complexity, using methods of Moser and Milley. Finally, we prove that the n-chain link with 2m or 2m+1 half-twists cannot be the minimal volume hyperbolic manifold with n cusps, provided n is at least 60 or |m| is at least 8, and we give computational data indicating this remains true for smaller n and |m|.

    Vujic Jelena

    2015-11-01

    Full Text Available The semantics of the articles is crucial for their proper usage in L2 speakers. However, we believe that for their proper acquisition a pairing of concrete form and concrete meaning must take place. In other words, a schema must be created for various meanings of articles. Therefore, in this paper English articles will be viewed from the aspect of Construction grammar. Working within the framework of CxG we will perceive the noun phrases of the type a/the+ N as lexico-syntactic meaningful constructions where the articles attribute a particular meaning to the noun(s they determine. Together they constitute Determination (article Construction. Each particular meaning of the articles can be conceptualized and adequate abstract constructional schemas and subschemas as a schematic pairing of form and meaning can be created. In addition, we will use the Serbo-Croatian semantic equivalents of English articles such as indefinite pronouns neki, poneki, koji, kakav, numerals jedan, ijedan, adverbs nekako and makar, demonstrative determiners onaj, adjectives, negative forms ni, nikakav, possessive pronominals and many more. They will serve as a starting point for offering possible constructional schema models for meaningful constructions a/the +N. Other meanings and usages of the articles will be treated in the same way.

    2012-01-01

    Today's Web of Data is noisy. Linked Data often needs extensive preprocessing to enable efficient use of heterogeneous resources. While consistent and valid data provides the key to efficient data processing and aggregation we are facing two main challenges: (1st) Identification of erroneous facts and tracking their origins in dynamically connected datasets is a difficult task, and (2nd) efforts in the curation of deficient facts in Linked Data are exchanged rather rarely. Since erroneous data often is duplicated and (re-)distributed by mashup applications it is not only the responsibility of a few original publishers to keep their data tidy, but progresses to be a mission for all distributers and consumers of Linked Data too. We present a new approach to expose and to reuse patches on erroneous data to enhance and to add quality information to the Web of Data. The feasibility of our approach is demonstrated by example of a collaborative game that patches statements in DBpedia data and provides notifications ...

    A single-electron tunneling (SET) device with a nanoscale central island that can move with respect to the bulk source- and drain electrodes allows for a nanoelectromechanical (NEM) coupling between the electrical current through the device and mechanical vibrations of the island. Although an electromechanical "shuttle" instability and the associated phenomenon of single-electron shuttling were predicted more than 15 years ago, both theoretical and experimental studies of NEM-SET structures are still carried out. New functionalities based on quantum coherence, Coulomb correlations and coherent electron-spin dynamics are of particular current interest.

    Apples, porcupines, and the most obscure Bob Dylan song--is every topic a few clicks from Philosophy? Within Wikipedia, the surprising answer is yes: nearly all paths lead to Philosophy. Wikipedia is the largest, most meticulously indexed collection of human knowledge ever amassed. More than information about a topic, Wikipedia is a web of naturally emerging relationships. By following the first link in each article, we algorithmically construct a directed network of all 4.7 million articles: Wikipedia's First Link Network. Here, we study the English edition of Wikipedia's First Link Network for insight into how the many articles on inventions, places, people, objects, and events are related and organized. By traversing every path, we measure the accumulation of first links, path lengths, groups of path-connected articles, cycles, and the influence each article exerts in shaping the network. We find scale-free distributions describe path length, accumulation, and influence. Far from dispersed, first links dis...

    2008-01-01

    Obesity predisposes toward renal disease independently of diabetes and hypertension. In this issue of the JCI, Sharma and colleagues assessed the role of adiponectin, an adipose-derived hormone, in the pathogenesis of albuminuria (see the related article beginning on page 1645). Obese African Americans had reduced adiponectin levels associated with albuminuria. Adiponectin deficiency in mice induced oxidative stress, fusion of podocyte foot processes in the kidney glomerulus, and urinary albu...

    The NASA Astrophysics Data System (ADS), along with astronomy's journals and data centers (a collaboration dubbed URANIA), has developed a distributed on-line digital library which has become the dominant means by which astronomers search, access and read their technical literature. Digital libraries such as the NASA Astrophysics Data System permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (``reads'') of individual articles. We explore various aspects of this new measure. We examine the obsolescence function as measured by actual reads, and show that it can be well fit by the sum of four exponentials with very different time constants. We compare the obsolescence function as measured by readership with the obsolescence function as measured by citations. We find that the citation function is proportional to the sum of two of the components of the readership function. This proves that the normative theory of citation is true in the mean. We further examine in...

  4. The Language of Islamophobia in Internet Articles

    2008-06-01

    Full Text Available Abstract: Islamophobia, the hatred for and fear of Islam and Muslims, manifests itself in physical, political, cultural, linguistic and other forms. From the linguistic perspective, many words have been coined to perpetuate prejudices against Muslims and their religion. Expressions are freely used to associate Islam, which means “peace” in Arabic, with concepts and actions which the religion and practising Muslims do not approve of, much less condone. Expressions such as Islamic terrorism, Islamic fanaticism, Muslim extremists, Islamist and political Islam have been used pejoratively. To strike fear and misgivings in the minds of many Europeans, the British capital has even been mischievously called “Londonistan” by anti-Muslim elements. Known Islamophobic items taken from Internet articles need to be analysed to respond objectively to linguistic Islamophobia.

  5. Rupture of pectoralis major muscle: review article

    2010-05-01

    Full Text Available "nBackground: Rupture of pectoralis major muscle is a very rare and often athletic injury. These days in our country this injury occurs more frequently. This could be due to increase in professional participation of amateur people in different types of sport, like body building and weight-lifting (especially bench-pressing without adequate preparation, training and taking necessary precautions. In this article, we have tried to review several aspects of complex anatomy of pectoralis major muscle, epidemiology, mechanism, clinical presentations, imaging modalities, surgical indications and techniques of its rupture. Complex and especial anatomy of pectoralis major muscle, in its humeral insertion particularly, have a major role of its vulnerability to sudden and eccentric contraction as the main mechanism of rupture. Also, restoration of this complex anatomy seems to be important during surgical repair to have normal function of the muscle again.

  6. Lymphangiosarcoma of dogs : a review : review article

    Directory of Open Access Journals (Sweden)

    J.H. Williams

    2005-06-01

    Full Text Available Lymphangiosarcoma in dogs, an extremely rare tumour with only 16 cases reported in the literature, is reviewed. Lymphangiosarcoma in humans, also very rare, and known in post-mastectomy, chronically-lymphoedematous patients as 'Stewart-Treves' syndrome, is briefly outlined, as well as the various other causes of lymphoedema, both primary and secondary, which usually precede malignancy. Comparisons between human and canine lymphoedema are made when such references were found. The genetic links to primary lymphoedema and the manifestation thereof in humans are mentioned. Lymphangiosarcoma in the majority of human and canine patients is an aggressively malignant tumour with few patients surviving despite various attempted treatments. The tumour most commonly arises in the subcutaneous tissues and rapidly invades underlying tissues and may spread widely internally via haematogenous and lymphatic routes, with frequent pleural and chest involvement. The tumour has been reported mostly in medium- to large-breed dogs, in slightly more males than females, and in an age-range of 8 weeks to 13 years, with more cases aged 5 years and older. Methods of diagnosis, with the variations encountered, including routine histopathology, immunohistochemistry, electron microscopy, tissue culture characteristics and endothelial expression of glycocongugates, are discussed.

  10. The Connectivity Order of Links

    CERN Document Server

    Dugowson, Stéphane

    2008-01-01

    We associate at each link a connectivity space which describes its splittability properties. Then, the notion of order for finite connectivity spaces results in the definition of a new numerical invariant for links, their connectivity order. A section of this short paper presents a theorem which asserts that every finite connectivity structure can be realized by a link : the Brunn-Debrunner-Kanenobu Theorem.

  11. Link Analysis for Space Communication Links Using ARQ Protocol

    Science.gov (United States)

    Cheung, Kar-Ming; Lau, Chi-Wung; Lee, Charles

    2014-01-01

    In space communications, standard link analysis assumes that messages are sent once. For a communication link that uses an error-correction coding scheme, bit-error-rate (BER) or frame-error-rate (FER), and link margins are common metrics that characterize the quality of a link, and they are used to determine the supportable data rate. With the advent of Automatic Repeat-reQuest (ARQ) protocols, when messages are corrupted during transmission, they can be resent multiple times automatically until they are correctly received and acknowledged. The concept of BER, FER, and link margin cannot be directly applied, and the link analysis approach for ARQ links needs to be re-examined.

  12. Predicting missing links and identifying spurious links via likelihood analysis

    Pan, Liming; Zhou, Tao; Lü, Linyuan; Hu, Chin-Kun

    2016-03-01

    Real network data is often incomplete and noisy, where link prediction algorithms and spurious link identification algorithms can be applied. Thus far, it lacks a general method to transform network organizing mechanisms to link prediction algorithms. Here we use an algorithmic framework where a network’s probability is calculated according to a predefined structural Hamiltonian that takes into account the network organizing principles, and a non-observed link is scored by the conditional probability of adding the link to the observed network. Extensive numerical simulations show that the proposed algorithm has remarkably higher accuracy than the state-of-the-art methods in uncovering missing links and identifying spurious links in many complex biological and social networks. Such method also finds applications in exploring the underlying network evolutionary mechanisms.

Digital libraries such as the NASA Astrophysics Data System \\citep{2005JASIS.tmp....2K} permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (``reads'') of individual articles. We explore various aspects of this new measure. We examine the obsolescence function as measured by actual reads, and show that it can be well fit by the sum of four exponentials with very different time constants. We compare the obsolescence function as measured by readership with the obsolescence function as measured by citations. We find that the citation function is proportional to the sum of two of the components of the readership function. This proves that the normative theory of citation is true in the mean. We further examine in detail the similarities and differences between the citation rate, the readership rate and the total citations for individual articles, and discuss some of the causes. Using the number of reads as a bibliometric measure for individuals, we introduce the read-cite diagram to provide a two-dimensional view of an individual's scientific productivity. We develop a simple model to account for an individual's reads and cites and use it to show that the position of a person in the read-cite diagram is a function of age, innate productivity, and work history. We show the age biases of both reads and cites, and develop two new bibliometric measures which have substantially less age bias than citations: SumProd, a weighted sum of total citations and the readership rate, intended to show the total productivity of an individual; and Read10, the readership rate for papers published in the last ten years, intended to show an individual's current

    In the last few years, the Life Sciences domain has experienced a rapid growth in the amount of available biological databases. The heterogeneity of these databases makes data integration a challenging issue. Some integration challenges are locating resources, relationships, data formats, synonyms or ambiguity. The Linked Data approach partially solves the heterogeneity problems by introducing a uniform data representation model. Linked Data refers to a set of best practices for publishing and connecting structured data on the Web. This article introduces kpath, a database that integrates information related to metabolic pathways. kpath also provides a navigational interface that enables not only the browsing, but also the deep use of the integrated data to build metabolic networks based on existing disperse knowledge. This user interface has been used to showcase relationships that can be inferred from the information available in several public databases. PMID:26055101

    In this chapter we propose to expand and enhance the understanding of wayfi nding beyond the strictly “instrumental” (i.e., getting from point A to point B), to include the qualities and multi-sensorial inputs that inform and shape people’s movement through space. We take as a point of departure...... of environmental information , which includes the embodied, multi-sensorial experience of moving through physical space. We base our examination in part on the classic positions of the wayfi nding literature—for example, Lynch’s seminal study, The Image of the City ( 1960 ). However, we also examine the so......-called mobilities turn in which mobility is viewed as a complex, multilayered process that entails much more than simply getting from point A to point B (see Cresswell 2006 ; Jensen 2013 ; Urry 2007 ).The structure of the chapter is simple: We fi rst introduce the concepts that are key to linking wayfi nding...

    2016-06-01

    We present an article viewer application that allows a scientific reader to easily discover and share knowledge by linking genomics-related concepts to knowledge of disparate biomedical databases. High-throughput data streams generated by technical advancements have contributed to scientific knowledge discovery at an unprecedented rate. Biomedical Informaticists have created a diverse set of databases to store and retrieve the discovered knowledge. The diversity and abundance of such resources present biomedical researchers a challenge with knowledge discovery. These challenges highlight a need for a better informatics solution. We use a text mining algorithm, Genomine, to identify gene symbols from the text of a journal article. The identified symbols are supplemented with information from the GenoDB knowledgebase. Self-updating GenoDB contains information from NCBI Gene, Clinvar, Medgen, dbSNP, KEGG, PharmGKB, Uniprot, and Hugo Gene databases. The journal viewer is a web application accessible via a web browser. The features described herein are accessible on www.genotation.org The Genomine algorithm identifies gene symbols with an accuracy shown by .65 F-Score. GenoDB currently contains information regarding 59,905 gene symbols, 5633 drug-gene relationships, 5981 gene-disease relationships, and 713 pathways. This application provides scientific readers with actionable knowledge related to concepts of a manuscript. The reader will be able to save and share supplements to be visualized in a graphical manner. This provides convenient access to details of complex biological phenomena, enabling biomedical researchers to generate novel hypothesis to further our knowledge in human health. This manuscript presents a novel application that integrates genomic, proteomic, and pharmacogenomic information to supplement content of a biomedical manuscript and enable readers to automatically discover actionable knowledge.

    Full Text Available Actinomycosis is an indolent, slowly progressive infection caused by anaerobic or microaerophilic bacteria, primarily of genus Actinomyces, which colonize the mouth, colon and vagina. Mucosal disruption may lead to infection virtually at any sites in the body. The aim of this study was to underline different features of actinomycosis and to represent total data about etiologic agents, clinical, diagnostic and therapeutic approaches these infections. From a total of 38 case reports or series, ninety one cases were obtained by using of relevant articles reported as recorded cases in Iran (1972 to 2012. Analyzed data represented 21 cases of oral-servicofacial (23.1%, 7 cases of thoracic (7.7%, 17 cases of abdominal (18.7%, 21 cases of disseminated forms (23.1% and 25 cases of others (27.5%. Findings indicated more common of these infections in men (61.5%. Actinomyces naeslundii (21 cases was found as the most common causative agents in comparison with A. Israeli (15 cases, A. viscosus (3 cases and A. bovis (1 case. The most patients had been successfully treated with penicillin although some cases needed surgery along with antibiotic therapy. Since some clinical features of actinomycosis are similar to malignancies, so the differential diagnosis of invasive forms must be considered. This report emphasizes on the importance of differential diagnosis of actinomycosis from similar diseases by clinicians.

    A significant development for conducting research on patient rights has been made in Iran over the past decade. This study is conducted in order to review and analyze the previous studies that have been made, so far, concerning patient rights in Iran. This is a comprehensive review study conducted by searching the Iranian databases, Scientific Information Database, Iranian Research Institute for Information Science and Technology, Iran Medex and Google using the Persian equivalent of keywords for 'awareness', 'attitude', and 'patient rights'. For pertinent Iranian papers published in English, scientific databases PubMed, and Google Scholar were searched using the keyword 'patient rights' and 'Iran'. A total of 41 Persian and five English articles were found for these keywords, only 26 of which fulfilled the objective of our study. The increasing number of papers published indicates that from 1999 onwards, this subject has begun to draw the attention of Iranian researchers in a progressive fashion and Iranian papers in English have also been compiled and published in international sources.

  20. Review article: burnout in emergency medicine physicians.

    Arora, Manit; Asha, Stephen; Chinnappa, Jason; Diwan, Ashish D

    2013-12-01

    Training and the practice of emergency medicine are stressful endeavours, placing emergency medicine physicians at risk of burnout. Burnout syndrome is associated with negative outcomes for patients, institutions and the physician. The aim of this review is to summarise the available literature on burnout among emergency medicine physicians and provide recommendations for future work in this field. A search of MEDLINE (1946-present) (search terms: 'Burnout, Professional' AND 'Emergency Medicine' AND 'Physicians'; 'Stress, Psychological' AND 'Emergency Medicine' AND 'Physicians') and EMBASE (1988-present) (search terms: 'Burnout' AND 'Emergency Medicine' AND 'Physicians'; 'Mental Stress' AND 'Emergency Medicine' AND 'Physicians') was performed. The authors focused on articles that assessed burnout among emergency medicine physicians. Most studies used the Maslach Burnout Inventory to quantify burnout, allowing for cross-study (and cross-country) comparisons. Emergency medicine has burnout levels in excess of 60% compared with physicians in general (38%). Despite this, most emergency medicine physicians (>60%) are satisfied with their jobs. Both work-related (hours of work, years of practice, professional development activities, non-clinical duties etc.) and non-work-related factors (age, sex, lifestyle factors etc.) are associated with burnout. Despite the heavy burnout rates among emergency medicine physicians, little work has been performed in this field. Factors responsible for burnout among various emergency medicine populations should be determined, and appropriate interventions designed to reduce burnout.

  1. FANTM, the First Article NIF Test Module

    International Nuclear Information System (INIS)

    Designing and developing the 1.7 to 2.1-MJ Power Conditioning System (PCS), that will power the flashlamps of the main and power amplifiers for the National Ignition Facility (NIF) lasers, is one of several responsibilities assumed by Sandia National Labs (SNL) in support of the NIF Project. Maxwell Physics International has been a partner in this process. The NIF is currently being constructed at Lawrence Livermore National Labs (LLNL). The test facility that has evolved over the last three years to satisfy the project requirements is called FANTM, for the First Article NIF Test Module. It was built at SNL and operated for about 17,000 shots to demonstrate component performance expectations over the lifetime of NIF. A few modules similar to the one shown in Fig. 1 will be used initially in the amplifier test phase of the project. The final full NIF system will require at least 192 of them in four capacitor bays. This paper briefly summarizes the final design of the FANTM facility and compares its performance with the predictions of circuit simulations for both normal operation and fault-mode response. Applying both the measured and modeled power pulse waveforms as input to a physics-based, semi-empirical amplifier gain code indicates that the 20-capacitor PCS can satisfy the NIF requirement for an average gain coefficient of 5.00 %/cm and can exceed 5.20 %/cm with 24 capacitors

  7. How to write a review article?

    Gülpınar, Ömer; Güçlü, Adil Güçal

    2013-09-01

    In the medical sciences, the importance of review articles is rising. When clinicians want to update their knowledge and generate guidelines about a topic, they frequently use reviews as a starting point. The value of a review is associated with what has been done, what has been found and how these findings are presented. Before asking 'how,' the question of 'why' is more important when starting to write a review. The main and fundamental purpose of writing a review is to create a readable synthesis of the best resources available in the literature for an important research question or a current area of research. Although the idea of writing a review is attractive, it is important to spend time identifying the important questions. Good review methods are critical because they provide an unbiased point of view for the reader regarding the current literature. There is a consensus that a review should be written in a systematic fashion, a notion that is usually followed. In a systematic review with a focused question, the research methods must be clearly described. A 'methodological filter' is the best method for identifying the best working style for a research question, and this method reduces the workload when surveying the literature. An essential part of the review process is differentiating good research from bad and leaning on the results of the better studies. The ideal way to synthesize studies is to perform a meta-analysis. In conclusion, when writing a review, it is best to clearly focus on fixed ideas, to use a procedural and critical approach to the literature and to express your findings in an attractive way.

    2014-10-01

    Full Text Available This study explores the rhetorical structure of introductions that are followed by an independent Literature Review (L section. It is motivated by an increasing use or even the prevalent use of both the introduction and L sections in the opening phase of empirical research articles in many disciplines and the lack of systematic genre-based investigation of introductions with a following L section. Based on a detailed examination of 30 introductions with a subsequent L section in Applied Linguistics, this study found that they generally can be classified into two categories according to their communicative functions and structures. They are the traditional CARS type that largely follows the classic “Create a Research Space” (CARS model and the innovative Two-move Orientation type. Some featured elements used in the introductions with a subsequent L are identified and the “Two-move Orientation” approach is formulated for the rhetorical structure of this new type of introductions. The interesting links between introduction and L are also suggested. The study contributes to our understanding of the structure and function of this important part-genre in a new generic context (that is, introductions being followed by an independent L section and illuminates the current genre-based teaching of introduction writing.

    UK PubMed Central (UKPMC) is a full-text article database that extends the functionality of the original PubMed Central (PMC) repository. The UKPMC project was launched as the first 'mirror' site to PMC, which in analogy to the International Nucleotide Sequence Database Collaboration, aims to provide international preservation of the open and free-access biomedical literature. UKPMC (http://ukpmc.ac.uk) has undergone considerable development since its inception in 2007 and now includes both a UKPMC and PubMed search, as well as access to other records such as Agricola, Patents and recent biomedical theses. UKPMC also differs from PubMed/PMC in that the full text and abstract information can be searched in an integrated manner from one input box. Furthermore, UKPMC contains 'Cited By' information as an alternative way to navigate the literature and has incorporated text-mining approaches to semantically enrich content and integrate it with related database resources. Finally, UKPMC also offers added-value services (UKPMC+) that enable grantees to deposit manuscripts, link papers to grants, publish online portfolios and view citation information on their papers. Here we describe UKPMC and clarify the relationship between PMC and UKPMC, providing historical context and future directions, 10 years on from when PMC was first launched. PMID:21062818

  11. Discovering link communities in complex networks by exploiting link dynamics

    International Nuclear Information System (INIS)

    Discovery of communities in complex networks is a fundamental data analysis problem with applications in various domains. Most of the existing approaches have focused on discovering communities of nodes, while recent studies have shown great advantages and utilities of the knowledge of communities of links in networks. From this new perspective, we propose a link dynamics based algorithm, called UELC, for identifying link communities of networks. In UELC, the stochastic process of a link–node–link random walk is employed to unfold an embedded bipartition structure of links in a network. The local mixing properties of the Markov chain underlying the random walk are then utilized to extract two emerging link communities. Further, the random walk and the bipartitioning processes are wrapped in an iterative subdivision strategy to recursively identify link partitions that segregate the network links into multiple subdivisions. We evaluate the performance of the new method on synthetic benchmarks and demonstrate its utility on real-world networks. Our experimental results show that our method is highly effective for discovering link communities in complex networks. As a comparison, we also extend UELC to extracting communities of nodes, and show that it is effective for node community identification. (paper)

Recent studies suggest that periodontal infection and the ensuing increase in the levels of inflammatory markers may be associated with myocardial infarction, peripheral vascular disease and cerebrovascular disease. The present article aimed at reviewing contemporary data on the pathophysiology of vascular endothelium and its association with periodontitis in the scenario of cardiovascular disease.

    A superconducting coil system includes a superconducting coil and a protective link of superconducting material coupled to the superconducting coil. A rotating machine includes first and second coils and a protective link of superconducting material. The second coil is operable to rotate with respect to the first coil. One of the first and second coils is a superconducting coil. The protective link is coupled to the superconducting coil.

    Link analysis methods show that the interconnections between web pages have lots of valuable information. The link analysis methods are, however, inherently oriented towards analyzing binary relations. We consider the question of generalizing link analysis methods for analyzing relational databases. To this aim, we provide a generalized ranking framework and address its practical implications. More specifically, we associate with each relational database and set of queries a unique weig...

  15. "Conjectural" links in complex networks

    This paper introduces the concept of Conjectural Link for Complex Networks, in particular, social networks. Conjectural Link we understand as an implicit link, not available in the network, but supposed to be present, based on the characteristics of its topology. It is possible, for example, when in the formal description of the network some connections are skipped due to errors, deliberately hidden or withdrawn (e.g. in the case of partial destruction of the network). Introduced a parameter ...

  16. Linking ecosystem processes to sustainable wetland management

    As a result of concern over problems associated with the future of managed wetlands in North America, nearly two dozen wetland scientists and managers met in February 2006 at Bosque del Apache National Wildlife Refuge in New Mexico and discussed a sustainable approach to wetland management. This approach links science with management by focusing on underlying wetland processes. From that meeting, several papers were developed and published in Wetlands to address these concerns (Euliss et al. 2008, Smith et al. 2008, Wilcox 2008). This article summarizes our first paper, Euliss et al. (2008), and a future Newsletter article will summarize Smith et al. (2008). Realization of the role that complex interactions play in maintaining ecosystems, coupled with increasing demands of humans for ecosystem services, has prompted much interest in ecosystem management. Not surprisingly, sustainability of ecosystems has become an explicitly stated goal of many natural resource agencies and, in some cases, has been legislatively mandated to ensure provision of resources for future generations. However, examples of sustainable ecosystem management are uncommon because management goals often focus on specific deliverables rather than processes that sustain ecosystems. This paper has three sections: (1) perspectives in which we provide a bit of history, (2), ecological consequences of a static view, and (3) suggestions to aid wetland managers link management goals with critical ecosystem processes responsible for provision of wetland services.

    This article reviews a range of literature of computer games and learning theories and attempts to establish a link between them by proposing a typology of games which we use as a new usability measure for the development of guidelines for game-based learning. First, we examine game literature in order to understand the key elements that…

    This paper introduces the concept of Conjectural Link for Complex Networks, in particular, social networks. Conjectural Link we understand as an implicit link, not available in the network, but supposed to be present, based on the characteristics of its topology. It is possible, for example, when in the formal description of the network some connections are skipped due to errors, deliberately hidden or withdrawn (e.g. in the case of partial destruction of the network). Introduced a parameter that allows ranking the Conjectural Link. The more this parameter - the more likely that this connection should be present in the network. This paper presents a method of recovery of partially destroyed Complex Networks using Conjectural Links finding. Presented two methods of finding the node pairs that are not linked directly to one another, but have a great possibility of Conjectural Link communication among themselves: a method based on the determination of the resistance between two nodes, and method based on the computation of the lengths of routes between two nodes. Several examples of real networks are reviewed and performed a comparison to know network links prediction methods, not intended to find the missing links in already formed networks.
