  11. Indirect cavernous carotid fistula in a 12-year-old girl

    Livi, Francesca; Ndoro, Samuel; Caird, John; Crimmins, Darach

    2016-01-01

    We present a very rare case of indirect cavernous carotid fistula (CCF) in a 12-year-old girl. Indirect CCF is extremely rare in the paediatric population. A 12-year-old girl presented with a 7-month history of frontal headaches and intermittent left-sided proptosis. On examination, she had dilated and engorged scleral veins on the left eye, mild dysdiadochokinesia and past pointing on the left side. A brain computer tomography with contrast, brain magnetic resonance imaging (MRI) and interventional radiography (IR) cerebral angiogram confirmed the diagnosis of CCF. The CCF was embolized and a follow-up brain MRI and an IR cerebral angiogram were conducted over the course of 8 months that revealed no evidence of residual CCF. CCF, though rare in the paediatric population, should be highly considered in the differential diagnosis when dilated scleral veins, proptosis and dysdiadokinesis are present in the clinical setting. Prompt treatment has good prognostic results. PMID:27273682

  13. Using the Debate Method for Teaching Argumentation to 10-12 Year-Old Children

    Y. V. Rybka

    2015-02-01

    Full Text Available The paper is devoted to peculiarities of using the debate method in teaching argumentation to 10–12 year-old children. The research is aimed at identifying the most effective ways and means of applying the given method. According to the author’s hypothesis, regular integration of discussions into the training course of rhetoric should promote learners’ argumentation, changing it from a mere fantasy through egocentric attitudes to the objective position expressed in a conclusive argumentative way. To achieve the research objectives, the experimental training method was developed applying the debate technique in the form of role plays adapted to peculiarities of children’s age. The experimental results indicated the decentration dynamics in the training process and, therefore, the effectiveness of the experimental training course. The presented training program can be used in teaching rhetoric to 10–12 year- olds, as well as in the optional argumentation course based on the debate technique. In addition, the analysis of children’s argumentation position in the context of socio-cognitive approach can give an impetus for further studies of children’s speech and thinking.

  16. Mucin ous cystadenoma of the ovary in a 12-year-old girl

    Benign mucinous cystadenomas MCA are rare benign neoplasms in the pediatric age group. Only 19 cases have been described before and they often present as large abdominal masses. We present a 12-year-old patient that had a huge mass arising from the left ovary causing bilateral hydronephrosis and renal insufficiency. The final pathology revealed a benign MCA. Patients with mucinous tumors usually present late, this may lead to renal insufficiency secondary to urinary outflow obstruction. Unilateral salpingo-oophorectomy is usually sufficient treatment for these cases. The diagnosis of MCA should be considered in children who present with huge pelvi-abdominal masses. Early recognition and intervention are necessary to avoid potential complications. (author)

    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.

    . Afsnypunte volgens die liggaamsmassa-indeks (LMI is gebruik om tussen oorgewig en obees te onderskei. Elke deelnemer het ‘n ACTICAL™ monitor gedra om hul fisieke-aktiwiteitsvlakke en TEV te bepaal. Die studie het getoon dat die TEV van die kinders op ’n weeksdag en naweekdag nie verskil het nie, alhoewel TEV tydens die middag van die weeksdag betekenisvol verskil het van die oggend s’n. Anders as die oorgewig kinders, het geen van die obese kinders aan die voorgestelde riglyn van 60 minute se matig intensiewe fisieke aktiwiteit per dag voldoen nie. Strategieë moet gevind word om die vlakke van aktiwiteit van oorgewig en veral obese kinders te verhoog, spesifiek gedurende die oggende en oor naweke.

    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.

    Dental plaster casts of 97 6-8-year-old and 173 12-year-old Maasai, Kikuyu, and Kalenjin children were studied. The Kikuyu are Bantu, while Maasai and Kalenjin are Nilo-Hamitic subjects. The variables measured were palatal depth (PD) and length (PL); maxillary and mandibular anterior arc circumferences (AC1) and (AC2), respectively; posterior arc circumferences (PC1) and (PC2), inter-canine (CC1), and (CC2); inter-molar (MM1) and (MM2) distances, and mandibular length (ML). The data were analysed using SPSS package. The mean values of all the variables were generally higher in the males compared with the females and significant sex differences in the means (P Kalenjin. Ethnic and sex differences in the dental arches may be masked by anterior tooth positions that are influenced by the dento-alveolar complex and soft tissues. Corresponding mandibular and maxillary variables were strongly correlated and anterior and posterior arc circumferences were correlated with inter-canine and intermolar distances. Details of the norms for dental arch dimensions and changes with age may allow for appropriate assessment of dental occlusion and treatment planning for Kenyan children. PMID:10822886

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

    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)

The changes in the age borders and childhood structure along with their causes are demonstrated. The childhood crisis is described, its place in the child’s development process identified. The author emphasizes the visible discord between the worlds of adults and children: being less involved in upbringing process nowadays, adults appear to be less exact in their attitude to children; their demands lack clearness and specificity. Both teachers and adults demonstrate helplessness and aloofness, which reflects in children’s consciousness and their attitude to adults, and results in the lost sense of responsibility, infantilism, egoism and moral emptiness of growing generation. The author carried out the comparative analysis of age peculiarities of middle class schoolchildren from comprehensive school. Three development stages were singled out for 10 to 12 year-olds: local caprices, rights understanding, and affirmative functional stage. The personality formation trends concerning the modern day school children are outlined, the external and internal factors determining this formation enumerated. The following influencing phenomena are mentioned, in particular: the essential socio-economic changes, fast spreading of mass-media and computer technologies, low level of parental motivation, replacement of the value-normative system (social anomie etc. The necessity of creating socio-pedagogic conditions relating to the age peculiarities of modern school children is substantiated.

    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

    Jeseem, MT; Kumar, TV Anupam

    2016-01-01

    ABSTRACT Background: A malocclusion is an irregularity of the teeth or a malrelationship of the dental arches beyond the range of what is accepted as normal. 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.

    2007-08-01

    Full Text Available 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. Conclusions: We emphasize the prevention need as core issue of the primary medical care in the world today; being the General-Integral Dentist a transforming agent that according to his/her formation is capable to assume the existent health problem and to modify it positively, acting from the earliest ages.

    2016-01-01

    Objective: To describe the imaging characteristics of sacrococcygeal teratomas and to review appropriate diagnostic evaluation and management. Clinical Features: 12-year-old otherwise healthy, asymptomatic female with an incidental pelvic mass found on routine scoliosis radiographs. Intervention and Outcome: The pelvic mass was further evaluated by MRI and CT scan. Management consisted of successful surgical resection with no postoperative complications. Pathology confirmed a mature, benign, sacrococcygeal teratoma. Conclusions: Chiropractors manage patients with scoliosis, which may include radiographic surveillance. Familiarity with the radiographic features of masses such as sacrococcygeal teratomas is important for prompt diagnosis and management. PMID:27069263

  10. Massive low-grade fibromyxoid sarcoma presenting as acute respiratory distress in a 12-year-old girl

    Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft-tissue sarcoma that usually presents in young adults as a painless, slow-growing mass. Evans first described LGFMS in 1987 as a spindle-cell sarcoma with bland histological features and paradoxically aggressive behavior. Although young adults are most frequently affected, recent reports describe pediatric cases being increasingly more common. Males and females are affected approximately equally and common locations include the deep soft tissue of the lower extremity, particularly the thigh and trunk. Primary occurrence within the chest cavity is exceedingly rare. Local recurrence and metastasis are not uncommon and present the clinician and radiologist with challenges regarding follow-up recommendations. Review of the literature reveals many cases of slowly progressive symptoms related to a mass effect. We present a healthy 12-year-old African-American girl who interestingly developed acute symptoms of shortness of breath and chest pain while playing with her brother. (orig.)

    2014-08-01

    Full Text Available : Granular cell tumor (GCT or Abrikossoff’s tumor, variously termed as myoblastoma, granular cell neurofibroma or granular cell schwannoma, is a rare entity, with a reported prevalence ranging from 0.019% to 0.03% of all human neoplasms. It can occur in any region of the body or soft tissues of any organ. It has been found that GCTs of the oral cavity can occur both in pediatric and advanced age, but their incidence usually peaks between the fourth and the sixth decade, while their occurrence before the age of 20 years is very rare. Here we represent a case of GCT affecting tongue of a 12 year old girl, which is a rare occurrence. Clinical & histopathological features have been discussed, also mentioning presence & distribution of immunohistochemical markers & a brief review of recent literature.

    2016-05-01

    Objective The Radiation and Nuclear Safety Authority in Finland has paid attention to the large numbers of dental panoramic tomographs (DPTs), particularly in 7-12-year-old children. The majority of these radiographs are taken for orthodontic reasons. Because of the high radiosensitivity of children, the size of the irradiated field should be carefully chosen to yield the necessary diagnostic information at the lowest possible dose. The purpose of the present study was, therefore, to assess the outcome of DPTs within this age group in terms of type and location of pathological findings. It was also hypothesized that DPTs of orthodontic patients rarely display unrestored caries. Materials and methods Four hundred and forty-one DPTs, taken of 7-12-year-old children in 2010-2014, were randomly sampled. The 413 of them (94%) that had been taken for orthodontic reasons were analysed. Results All pathologic findings were restricted to the tooth-bearing area and there was no pathology in the bone structure or any incidental findings in the region of temporomandibular joint. Unlike hypothesized, 27% of the orthodontic DPTs showed caries in deciduous teeth and 16% in permanent teeth. A sub-sample of 229 DPTs, analysed for developmental dental and occlusal problems, most commonly displayed crowding (50%), positional anomalies and local problems with tooth eruption (32%), as well as hyperodontia (15%). Conclusion Inclusion of only the actual area of interest in the image field should be considered case-specifically as a means to reduce the radiation dose. PMID:26634313

    Full Text Available Introduction and objective: Tooth caries is the most prevalent infectious disease in children. The purpose of this study was to assess carries experience indexes and related factors among 7-12 year-old school children in Yasuj, Iran, in 2014. Materials and methods: In the present Cross-sectional and analytical study, using a two-stage random sampling, 460 students from primary schools of Yasuj city and surrounding villages were selected. The children were clinically examined at their school by a professional calibrated dentistry team. Their demographic and socioeconomic status, mouth health behaviors and teeth carries status and consumed nutritional materials were gathered by a questioner and a dental chart. The data were analyzed using inferential statistical methods. The SPSS software version 22 was used to extract the outputs and &alpha=0.05 was considered as the significant level. Results: The dental caries prevalence of deciduous, permanent and total of  two type of dents were  75.2, 41.1 and  89.8 percent, respectively and the dmft, DMFT and dmft+DMFT indexes were 3.57, 0.87, and 4.44, respectively.. The caries prevalence of permanent teeth and DMFT in girls were significantly higher than boys (p=0.046, but the caries prevalence in total of dents in boys was significantly higher than girls ( p=0.32. Furthermore, the dental caries prevalence in permanent teeth and DMFT in children resident in rural areas were significantly higher than those in urban areas (p0.1.  Conclusions: Prevalence and severity score of dental caries among 7 - 12 year-old Yasuj students were higher than the WHO standards. The tooth caries experiences were more prevalent in boys and in children resident in rural areas, increased with age and decreased with BMI and less prevalent in children with higher family socioeconomic status.

    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.

    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.

    2012-01-01

    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.

    2012-09-01

    Research on the genetic influences on different abstract reasoning skills (fluid intelligence) and their interrelation (especially in childhood/adolescence) has been sparse. A novel cognitive test battery, the Verbal and Spatial Reasoning test for Children (VESPARCH 1), consisting of four matched (in terms of test-procedure and design) subtests assessing verbal [analogical (VA) and categorical (VC)] and spatial [analogical (SA) and categorical (SC)] reasoning, was administered to a population based sample of 12-year old twins (169 pairs). Multivariate analysis was conducted to explore the genetic relationship between the four cognitive sub-domains. Heritabilities were 0.62 (VA), 0.49 (VC), 0.52 (SA), and 0.20 (SC). Genetic influences were due to one common factor with no specific genetic influences. This shared genetic factor also explained almost the entire covariance between the domains, as environmental variance was largely specific to each subtest. The finding of no genetic influences specific to each subtest may be due to the uniquely matched design of the VESPARCH 1, reducing confoundment of different test modalities used in conventional tests. For future research or when interpreting previous studies, our findings highlight the importance of taking such potential artefacts (i.e. different test modalities for different sub-domains) into account when exploring the relationship between cognitive sub-domains.

  4. Central low-grade osteosarcoma with an unusual localization in the diaphysis of a 12-year old patient

    Low-grade central osteosarcoma is a very rare subtype of osteosarcoma with a predilection for the metaphysis of long bones and a peak incidence in the 3rd decade of life. Absence of specific clinical symptoms and a good prognosis after wide resection are the characteristics of this entity. Chemotherapy is not indicated in this highly differentiated tumour. A 12-year old girl presented with limping, swelling and pain in the mid of the left femur. Radiography showed a 12 cm long intraosseous expansion with lamellated periosteal reaction and contrast medium enhancement in MRI. Although radiology led to the differential diagnoses of Ewing’s sarcoma, osteomyelitis and fibrous dysplasia, the histological specimen showed a hyopocellular spindle-cell proliferation arranged in fascicles with mild cytologic atypia and only single mitotic figures. In synopsis with radiology the diagnosis of low-grade central osteosarcoma was made and confirmed by reference pathology. The tumour was resected with wide margins and reconstruction was performed with a vascularized fibula, a homologous allograft and a plate. Staging was negative for recurrence and metastasis at a follow-up of 16 months. Low-grade osteosarcoma accounts for only 1% of all osteosarcomas with a peak incidence in the 3rd decade. The diaphyseal localization and the young age make this case special. To achieve the correct diagnosis of this rare low-grade entity and thereby the adequate treatment, despite a wide range of differential diagnoses, a multidisciplinary approach is essential

One group (50 patients received 20 mcg nasal vasopressin which increased up to 40 mcg, depending on the patients' response. The other group (50 patients received 0.2 mg oral vasopressin which increased up to 0.4 mg.The patients were followed up for one month after response to the last dose of drug. Data were recorded in prepared forms and analyzed using Chi-Square and Fisher Test.ResultsThe success rate with oral and nasal method was 80% and 92%, respectively (P=0.08. Only 2% of the children had complications during the treatment; one child treated orally developed gastroenteritis and another child treated with the nasal method developed convulsions (P=1. Sixteen percent of the children treated with the oral method and 28% of the children treated with the nasal method had recurrence (P=0.148.ConclusionOral and nasal forms of vasopressin have equal therapeutic effects. However, oral form of the treatment has fewer serious side effects and is easier to use. Therefore, the use of oral medicine is recommended.

  6. Right hepatic vein injury after blunt abdominal trauma in a 12-year-old boy- case report

    Blunt abdominal trauma in children is one of the most frequent causes of hospitalization. We present a rare case of traumatic liver injury. A 12-year-old boy was admitted to the Surgery Department after a bicycle fall and handlebar impact injury to the right infracostal area. At admission he was stable, with no abnormalities except for a subcutaneous hepatoma found in the injured area. Abdominal ultrasound examination revealed free intraperitoneal fluid. Computed tomography (CT) revealed irregular branching laceration of the right superior hepatic segments with extension into the hepatic veins. No active extravasation of contrast material was seen. On the next day, cause of the deterioration of the patient's condition, CT examination was repeated and revealed focal extravasation of contrast material in the portal hilum posterior to the gallbladder. An injury of the right hepatic vein was found on laparotomy. Hepatic vein injury is a rare but very serious complication after blunt liver trauma and it is an indication for surgical treatment. Diagnostic imaging is essential for therapeutic decisions, but its value is sometimes limited.The precise analysis of injury mechanism and localization may be very helpful.CT is currently the modality of choice for the evaluation of blunt liver trauma. If an active bleeding is suspected the delayed scans seem to be recommended. (author)

Methods: A cross-sectional study was carried out using a representative sample (n = 1217 of the population of 12-year-old schoolchildren in Galiza (northwest Spain. 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.

  9. Parental encouragement is positively associated with outdoor active play outside of school hours among 7-12 year olds.

    Ferrao, Thomas; Janssen, Ian

    2015-01-01

    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

    2009-07-01

    Full Text Available Abstract Background Socioeconomic differences in oral health have been reported in many countries. Poverty and social exclusion are two commonly used indicators of socioeconomic position in Latin America. The aim of this study was to explore the associations of poverty and social exclusion with dental caries experience in 12-year-old children. Methods Ninety families, with a child aged 12 years, were selected from 11 underserved communities in Lima (Peru, using a two-stage cluster sampling. Head of households were interviewed with regard to indicators of poverty and social exclusion and their children were clinically examined for dental caries. The associations of poverty and social exclusion with dental caries prevalence were tested in binary logistic regression models. Results Among children in the sample, 84.5% lived in poor households and 30.0% in socially excluded families. Out of all the children, 83.3% had dental caries. Poverty and social exclusion were significantly associated with dental caries in the unadjusted models (p = 0.013 and 0.047 respectively. In the adjusted model, poverty remained significantly related to dental caries (p = 0.008, but the association between social exclusion and dental caries was no longer significant (p = 0.077. Children living in poor households were 2.25 times more likely to have dental caries (95% confidence interval: 1.24; 4.09, compared to those living in non-poor households. Conclusion There was support for an association between poverty and dental caries, but not for an association between social exclusion and dental caries in these children. Some potential explanations for these findings are discussed.

    2011-07-01

    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.

    Full Text Available ObjectiveNocturnal enuresis is a common childhood problem and has various  treatments.This study was carried out to compare oral and nasal vasopressin in the treatment of nocturnal enuresis in 5- to 12-year-old children who were referred to the Shahid Beheshti Clinic in 2008.Materials & MethodsThis study included 100 children (62 males and 38 females with nocturnal enuresis. One group (50 patients received 20 mcg nasal vasopressin which increased up to 40 mcg, depending on the patients' response. The other group (50 patients received 0.2 mg oral vasopressin which increased up to 0.4 mg.The patients were followed up for one month after response to the last dose of drug. Data were recorded in prepared forms and analyzed using Chi-Square and Fisher Test.ResultsThe success rate with oral and nasal method was 80% and 92%, respectively (P=0.08. Only 2% of the children had complications during the treatment; one child treated orally developed gastroenteritis and another child treated with the nasal method developed convulsions (P=1. Sixteen percent of the children treated with the oral method and 28% of the children treated with the nasal method had recurrence (P=0.148.ConclusionOral and nasal forms of vasopressin have equal therapeutic effects. However, oral form of the treatment has fewer serious side effects and is easier to use. Therefore, the use of oral medicine is recommended.Keywords:Nasal vasopressin, Nocturnal enuresis, Oral vasopressin

    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

    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

  8. Cephalometric analysis of hard and soft tissues in a 12-year-old syndromic child: A case report and update on dentofacial features of Crouzon syndrome

    K Nagaraju

    2011-01-01

    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.

    2016-07-01

    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

    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

  13. Idiopathic infantile arterial calcification in a 12-year-old girl presenting as chronic mesenteric ischemia: imaging findings and angioplasty results

    We report an unusual case of chronic mesenteric ischemia presenting in a 12-year-old girl with idiopathic infantile arterial calcinosis (IIAC). This is the first reported case in the literature of chronic mesenteric ischemia in the setting of IIAC. The girl presented with a classical history of postprandial abdominal pain. Imaging demonstrated significant stenoses of the celiac axis, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). Angioplasty of the celiac axis and SMA was attempted, with successful dilation of the SMA only. At 3-, 6- and 12-month follow-ups, the child's symptoms had almost resolved. This case report has three important ramifications: chronic mesenteric ischemia is a possible clinical presentation in children with IACC, pre-angioplasty imaging is important in guiding treatment approach, and angioplasty was effective in this case of chronic mesenteric ischemia and offers hope for other similarly affected children.

    2016-01-01

    Objective: To report a case of a 12-year-old boy with intellectual disability and attention deficit hyperactivity disorder, who came to surgery for an examination due to a minor bulge on the left thumb, which had been growing for the previous month. His mother denied any trauma. Methods: After the removal of the clinically ambiguous bulge and a pathohistological confirmation that it was a periungual fibroma, complete patient analysis was performed due to the presence of hypomelanotic macules and a suspected tuberous sclerosis. Results: Considering the presence of hypomelanotic macules, as one of the main criteria, possible TS diagnosis was set. Conclusion: Early detection of the symptoms of TS enables a timely provision of protocols for further patient monitoring, which affects the patient’s morbidity and mortality.

  15. Neuroendocrine tumor of the pancreas causing biliary obstruction in a 12 year-old girl: A case report and literature review

    Kimberly A. Bertens

    2014-09-01

    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.

    2016-01-01

    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.

    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

  19. Loving and angry? Happy and sad? Understanding and reporting of mixed emotions in mother-child relationships by 6- to 12-year-olds.

    Heubeck, Bernd G; Butcher, Phillipa R; Thorneywork, Kristie; Wood, Jeff

    2016-06-01

    The Evaluative Space Model of emotions allows for the coactivation of positive-appetitive and negative-avoidant systems, but few studies have examined mixed emotions in child development. Existing research suggests children's understanding of opposite valence emotion combinations emerges by approximately 11 years of age. However, it is not yet clear whether various opposite valence combinations are understood at different ages, nor whether children can understand them in others before they have experienced such mixed emotions themselves. Semi-structured interviews with 97 children investigated whether they regarded six combinations of opposite valence mixed emotions as possible, could provide reasons for them, and report their own experience of each in the context of mother-child relationships. Both understanding that such combinations are possible and ability to provide reasons for them increased after age 6 and up to age 11, but were still incomplete in 12-year-olds. Understanding of different opposite valence combinations developed at different rates. At each age, fewer children who showed understanding of these combinations in others reported having had a similar experience themselves. The findings suggest a need to systematically examine a range of mixed emotions in order to develop a comprehensive theory of the development of mixed emotion understanding. They also suggest extending research into adolescence. PMID:26676630

    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.

    The effects of supplementation of the diets of 6- to 12-year-old children in a village near Shiraz in Iran with zinc plus iron or iron alone, together with the indispensable amino acids in the form of egg white protein, vitamins, minerals, and corn oil have been evaluated. Initially 48 of 59 children had zinc concentrations below the minimum found in well-nourished persons. Eight months of supplementation with zinc plus iron (20 mg daily of elemental zinc as carbonate and 20 mg ferrous iron as fumarate) failed to stimulate growth or bone development or to bring about an increase in plasma zinc concentrations. However, supplementation with iron in the above amount was associated with an acceleration of growth in height and weight. The persistence of low concentrations of zinc in plasma and the failure of supplemental zinc to stimulate growth are attributed to the poor availability of both dietary and supplemental zinc resulting from sequestering action of fiber and phytate present in large amounts in the unleavened whole meal bread consumed by villagers. In addition, the results suggest that simultaneous administration of iron and zinc supplements may impair utilization of the metals. PMID:1146725

    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

    2015-01-01

    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.

  10. Micro-RNAs Let7e and 126 in Plasma as Markers of Metabolic Dysfunction in 10 to 12 Years Old Children.

    Bernardo J Krause

    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.

    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

  17. Assessment of neuropsychological function through use of the Cambridge Neuropsychological Testing Automated Battery: performance in 4- to 12-year-old children.

    Luciana, Monica; Nelson, Charles A

    2002-01-01

    In this article, children's performance on subtasks from the Cambridge Neuropsychological Testing Automated Battery (CANTAB) is described. Two samples were recruited, one of which included children who spoke English as a second language. Children in this group also completed subtests from the Wechsler Intelligence Scale for Children-Third Revision (WISC-III). Despite the fact that ESL children scored over 1 SD below the norm on the WISC-III Vocabulary subtest, there were no CANTAB performance distinctions between primary versus secondary English-language speakers. In addition, several aspects of CANTAB performance were significantly correlated with verbal and nonverbal IQ. When developmental trends were examined, findings indicated that several aspects of frontal lobe function (memory span, working memory, and planning skills) are not functionally mature, by the age of 12 years. Implications for use of the CANTAB in clinical studies are discussed. PMID:12661972

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.

    2012-01-01

    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.

    Full Text Available Background and purpose: With respect to the high prevalence of goiter in Semirom before the initiation of National Program for Elimination of Iodine Deficiency Disorders (NPEIDD, the impact of the program on the prevalence of goiter in 8-12 years old students of Semirom was investigated in this study, after 15 years of sucessful execution of NPEIDD.Materials and Methods: After excluding students with any clinical evidence of hyper- or hypo-thyroidism, 1817 students aged 8-12 years were recruited based on a cluster sampling method. The participants were examined for the presence of goiter by experiencd endocrinologists. Urinary iodine was measured in 182 examined students, too. Chi- Square statistical method was used to analyze the data.Results: Goiter was detected in 36.7% of the students (grade 1: 30.4%, grade 2: 6.3%. The median urinary iodine was 18.5 and mean was 19.37 ± 9.22 μg/dl in collected specimens.Conclusion: The adequacy of urinary iodine in students of Semirom confirms the success of NPEIDD, however, the higher than expected prevalence of goiter in the region suggests the probable role of other goitrogenous or autoimmune factors. Further studies should be performed to investigate the possible causes.

  7. 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

    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. Children with high levels of independent mobility and good cycling skills perceived by their parents were more likely to always cycle to school (resp.

    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. Conclusions: We emphasize the prevention need as core issue of the primary medical care in the world today; being the General-Integral Dentist a transforming agent that according to his/her formation is capable to assume the existent

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.

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 Nesse estudo, foi estimada a frequência de parasitoses intestinais em 383 crianças do bairro Pinto Madeira em Crato, Estado do Ceará. Os dados foram obtidos por meio de inquérito domiciliar e de exame coproparasitológico abrangendo residências com crianças de quatro a 12 anos, foram utilizados os métodos de Kato-Katzo e Faust. Foi identificada uma associação de parasitoses intestinais com saneamento, disponibilidade e manuseio da água, com prevalência de Ascaris lumbricoides dentre os helmintos e Entamoeba sp. dentre os protozoários. Os dados obtidos demonstraram ainda a que prevalência de helmintos e protozoários foi significativamente maior para as crianças do sexo masculino de 4-5 anos e feminino de 6-7, filhos de mães com menor escolaridade, residentes nos domicílios com piores condições de abastecimento d’água e menor condições de higiene corporal e saneamento básico. Estes resultados sugerem que investimentos em infraestrutura básica e a adoção de políticas voltadas para melhorar a educação familiar poderiam contribuir significativamente na redução da prevalência das parasitoses intestinais em crianças.In this study, we estimated the frequency of intestinal parasites in 383 children in the Pinto Madeira neighborhood of Crato-Ceará State. A survey was conducted covering households with 4- to 12-year-old children, including interviews and coprological surveys using the Kato-Katz and Faust methods. An association was identified between intestinal parasitosis and sanitation, forms of use and availability of water. The prevalence of Ascaris lumbricoides and Entamoeba sp was demonstrated. The data also showed that the prevalence of helminths and protozoa was significantly higher for 4- to 5-year-old boys and 6- to 7-year-old girls, children of mothers with less education, living in households with poor conditions of water supply, hygiene and sanitation. These results suggest that investments in sanitary

    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.

  1. Interventions shown to aid executive function development in children 4 to 12 years old.

    Diamond, Adele; Lee, Kathleen

    2011-08-19

    To be successful takes creativity, flexibility, self-control, and discipline. Central to all those are executive functions, including mentally playing with ideas, giving a considered rather than an impulsive response, and staying focused. Diverse activities have been shown to improve children's executive functions: computerized training, noncomputerized games, aerobics, martial arts, yoga, mindfulness, and school curricula. All successful programs involve repeated practice and progressively increase the challenge to executive functions. Children with worse executive functions benefit most from these activities; thus, early executive-function training may avert widening achievement gaps later. To improve executive functions, focusing narrowly on them may not be as effective as also addressing emotional and social development (as do curricula that improve executive functions) and physical development (shown by positive effects of aerobics, martial arts, and yoga).

    2011-08-01

    The aim of this study was to establish orthodontic treatment need according to the Dental Aesthetic Index (DAI) and Aesthetic Component (AC) and Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and to determine its association with gender among Saharan schoolchildren. The study was carried out in accordance with World Health Organization (WHO) recommendations for oral health surveys at 12 years of age. The sample comprised 248 Sahrawi children (135 girls and 113 boys) living in refugee camps in Tindouf, Algeria. None of the children had previously received any orthodontic treatment. A chi-square test was used to analyse the IOTN results by gender, and a Student's t-test was employed for the DAI results. The mean DAI was 23.32 with a standard deviation of 6.05, 4 percent with a very severe and 9.2 per cent with severe malocclusion. Orthodontic treatment need was 16.1 and 2.0 percent, respectively, according to grades 4 and 5 of the IOTN DHC, 13.7 percent according to the IOTN AC, and 28.6 percent according to the modified IOTN (IOTN DHC grades 4-5 and/or IOTN AC grades 8-10). There were no statistically significant differences by gender. The orthodontic treatment need of Western Saharan schoolchildren is similar to that reported by many recent studies in European and in Sub-Saharan countries. PMID:20926555

    2016-04-01

    Melkersson-Rosenthal syndrome (MRS) is an uncommon granulomatous disease characterized by the triad of relapsing facial paralysis, orofacial swelling, and fissured tongue. Genital swelling in MRS is rarely reported. We presented the first case of complete MRS with genital swelling in a child. Biopsy examinations of both the child's lower lip and penis showed noncaseating granuloma and intralymphatic granuloma infiltration. No symptoms or signs of other systemic disease (Crohn's disease or sarcoidosis) were observed after 2 years of follow-up. Genetic screening for CARD15/NOD2 in this patient showed negative, which further confirmed the diagnosis of MRS. Eleven other cases of suspected complete or incomplete MRS with genitalia involved were reviewed. Our case emphasizes the specific clinical feature of MRS with genitalia involved, which was genetically different from Crohn's disease and could be an independent entity. Lymphatic obstruction is responsible for localized edema in MRS. PMID:27081272

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 Adequate controlled clinical trials in pediatric population, especially in oncology and vaccinations are still insufficient due to ethical considerations. Certain conditions in children in general and in Indian children in particular, suggested the need for Adverse Drug Reaction (ADR monitoring. Thus this study was aimed to investigate the incidence of ADRs in pediatric populations. A prospective spontaneous reporting study was conducted over a period of six months from October 2012 to March 2013 in pediatric inpatients ward of Bharati Hospital in Pune. Reported ADRs were assessed for its causality by using WHO causality assessment scale, and its severity by using Hart wig Severity Scale. A total of 107 suspected ADRs were reported and evaluated from 54 patients, showing an overall incidence of 4.75%. Incidence rate of ADRs during hospitalization was 4.13%, while ADRs induced hospitalization was 0.62%. The gastrointestinal system (48.59% was the most affected, and antibiotics was the most common the drug class associated to ADRs. In term of causality, 55.14% of the reactions were classified as possible, while in term of severity, 64.49% were classified as moderate. Most patients (60.75% recovered from the incidence. Although the prevalence and severity of ADRs in pediatrics populations is reported to be higher than those of in adults, the incidence of ADRs in our study was only 4.75% which is lower than those of reported in adults, this may due to the spontaneous reporting system that used in this study.

    Full Text Available X-linked agammaglobulinemia (XLA is a primary immune deficiency characterized by recurrent bacterial infections and profoundly depressed serum immunoglobulin levels and circulating mature B cells. We describe a 12-year-old boy with XLA and enthesitis-related arthritis (ERA. To date, there has been a paucity of reports of noninfectious inflammatory arthritis in children with XLA. This case illustrates that functional B cells and/or immunoglobulin are not required for ERA pathogenesis. In addition, this case suggests a possible link between immune deficiency, immune dysregulation, and rheumatic illness.

  9. Epidemiology of traumatic injuries to the permanent incisors of 9-12-year-old schoolchildren in Damascus, Syria.

    Marcenes, W; al Beiruti, N; Tayfour, D; Issa, S

    1999-06-01

    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

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

    Fabrizio Guarneri

    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.

    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.

    2008-05-01

    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.

  11. Media use, face-to-face communication, media multitasking, and social well-being among 8- to 12-year-old girls.

    Pea, Roy; Nass, Clifford; Meheula, Lyn; Rance, Marcus; Kumar, Aman; Bamford, Holden; Nass, Matthew; Simha, Aneesh; Stillerman, Benjamin; Yang, Steven; Zhou, Michael

    2012-03-01

    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.

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

    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.

  7. Dehumanization in children: the link with moral disengagement in bullying and victimization.

    van Noorden, Tirza H J; Haselager, Gerbert J T; Cillessen, Antonius H N; Bukowski, William M

    2014-01-01

    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.

  8. Two-dimensional ranking of Wikipedia articles

    Zhirov, A. O.; Zhirov, O. V.; Shepelyansky, D. L.

    2010-10-01

    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.

    Collaborative content creation inevitably reaches situations where different points of view lead to conflict. We focus on Wikipedia, the free encyclopedia anyone may edit, where disputes about content in controversial articles often reflect larger societal debates. While Wikipedia has a public edit history and discussion section for every article, the substance of these sections is difficult to phantom for Wikipedia users interested in the development of an article and in locating which topic...

  1. Dancing links

    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...

    2012-01-01

      Currently, there has been a growing interest in the study of academic writing; focusing on the structural organization of academic text or specific linguistic features. However, very few studies have been done on the structural organization of the Methods and the linguistic features link to each move. Thus, the purpose of this study is to identify rhetorical structure of the Methods of agricultural science research articles and to explore the linguistic features linked to each identified move, by analyzing thirty research articles based on Kanoksilapatham’s (2005) framework. Altogether, five moves were found in the Methods, showing that rhetorical structure of Methods in agricultural science has its own format. The moves and linguistic features realizing rhetorical functions may help novice researchers or learners write the Methods of science research articles effectively and professionally

    2013-01-01

    Results and Discussion: For −308 polymorphism, 37 of 42 PANDAS patients′ results and for −850 C/T polymorphism, 38 of 42 PANDAS patients′ results were obtained. According to our statistical analysis there is a positive relationship between PANDAS patients for −308 G/A polymorphism but not for −850 C/T polymorphism. There is no positive relationship between −308 G/A polymorphism and antistrep-tolysin O (ASO titers and no relationship between −850 C/T polymorphism and ASO titers. We found, however, positive relationship between genders of patients (boys and the disease. According to our results, we propose that the AA polymorphism of −308 G/A polymorphism can be used as a molecular indicator for PANDAS.

    Ducheyne Fabian; de Bourdeaudhuij Ilse; Spittaels Heleen; Cardon Greet

    2012-01-01

    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 enviro...

    2009-01-01

    Full Text Available El presente estudio instrumental pretende analizar la estructura factorial del Screen for Child Anxiety Related Emotional Disorders (SCARED en una muestra española utilizando tanto análisis factorial exploratorio como confirmatorio. 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.

  1. The effect of the UP4FUN pilot intervention on objectively measured sedentary time and physical activity in 10–12 year old children in Belgium: the ENERGY-project

    Verloigne Maïte

    2012-09-01

    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.

  3. Changes in 10-12 year old's fruit and vegetable intake in Norway from 2001 to 2008 in relation to gender and socioeconomic status - a comparison of two cross-sectional groups

    van Stralen Maartje M

    2011-10-01

    Full Text Available Abstract Background Norwegian children and adolescents eat less than half of the recommended 5 portions of fruit and vegetables (FV per day. Gender and socioeconomic disparities in FV consumption shows that boys and children of lower socioeconomic status (SES eat less FV than girls and high SES children. We also know that accessibility and preferences has been identified as two important determinants of FV intake. The objectives of this study were to compare FV intake among Norwegian 6th and 7th graders in 2001 and 2008, to explore potential mediated effects of accessibility and preferences on changes in FV over time, to explore whether these changes in FV intake was moderated by gender and/or SES and whether a moderated effect in FV intake was mediated by accessibility and preferences of FV. Methods The baseline survey of the Fruits and Vegetables Make the Marks project was conducted in 2001 at 38 randomly chosen schools in two Norwegian counties. A second survey was conducted at the same schools in 2008. A total of 27 schools participated in both surveys (2001 n = 1488, 2008 n = 1339. FV intake was measured by four food frequency questions (times/week in a questionnaire which the pupils completed at school. SES was based on parents' reports of their own educational level in a separate questionnaire. The main analyses were multilevel linear regression analyses. Results A significant year*parental educational level interaction was observed (p = 0.01. FV intake decreased among pupils of parents with lower educational level (13.9 vs. 12.6 times/week in 2001 and 2008, respectively, but increased among pupils of parents with higher education (14.8 vs. 15.0 times/week, respectively. This increasing SES disparity in FV intake was partly mediated by an increasing SES disparity in accessibility and preferences over time, wherein children with higher educated parents had a steeper increase in accessibility and preferences over time than children with lower educated parents. The year*sex interaction was not significant (p = 0.54. Conclusions This study shows an increase in SES disparities in 6th and 7th graders FV intake from 2001 to 2008, partly mediated by an increasing SES disparity in accessibility and preferences of FV.

    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 O objetivo deste trabalho foi avaliar os mecanismos de processamento da informação viso-espacial em crianças. 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.

    of JCE in the mail each month, and I expect you do too. I can glance at the cover to get an overview of an issue's content, and I usually am enticed inside by intriguing cover art. 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). In the table of contents, find the article "UV Catalysis, Cyanotype Photography, and Sunscreens". Click on the title. When the abstract appears, click on Full Text (PDF) to see the article, just as it appears on page 1199 in this issue. When you are prompted, enter the name and subscriber number from your address label. At the end of the article you will find that supplementary materials are available (including a procedure for testing sunscreens) and you can click on the link to view them

    Kim, Yeseul; Weon, Byung Mook

    2016-01-01

    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.

  17. Finding and Recommending Scholarly Articles

    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.

  20. Why does attention to web articles fall with time?

    Simkin, M V

    2012-01-01

    We analyze access statistics for a few dozen blog entries for a period of several years. Access rate falls as an inverse power of time passed since publication. The power law holds for periods up to thousand days. The exponents are different for different blogs and are distributed between 1 and 3. Decay of attention to aging web articles has been reported before and two explanations were proposed. One explanation introduced some decaying with time novelty factor. Another used some intricate theory of human dynamics. We argue that the decay of attention to a web article is simply caused by the link to it first dropping down the list of links on the website's front page, disappearing from the front page and subsequent movement further into background.

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

    Marygold Steven J

    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

Iran J Child Neurol. 2014 Summer;8(3: 1-5.AbstractObjectiveInfantile spasm (IS is a convulsive disease characterized by brief, symmetric axial muscle contraction (neck, trunk, and/or extremities. 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.

  9. 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.

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

    Rashid Ban Mousa

    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

  7. MEASURING SEMANTIC RELATEDNESS BETWEEN TWO WIKIPEDIA ARTICLES

    Dhanya Raghu

    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

  10. Measuring the Interestingness of News Articles

    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.

  17. Links and Quantum Entanglement

    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.

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

    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.

  8. Citation pattern of newsworthy research articles

    Manjari Manisha

    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.

  11. Discovering opinion leaders for medical topics using news articles

    Jonnalagadda Siddhartha

    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

    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.

  9. An Auction Market for Journal Articles

    Prüfer, J.; Zetland, D.

    2007-01-01

    Economic articles are published very slowly. We believe this results from the poor incentives referees face. We recommend that an auction market replace the current, push system for submitting papers and demonstrate that our proposed market has a stable, Pareto-improving equilibrium. Besides the benefits of speed, this pull mechanism increases the quality of articles and journals and rewards referees for their effort. Although the auction price gives a prior on a paper's future value, its act...

    Sale, Arthur

    2006-01-01

    The behavior of researchers when self–archiving in an institutional repository has not been previously analyzed. This paper uses available information for three repositories analyzing when researchers (as authors) deposit their research articles. The three repositories have variants of a mandatory deposit policy. It is shown that it takes several years for a mandatory policy to be institutionalized and routinized, but that once it has been the deposit of articles takes place in a remarkab...

  11. Biaxially textured articles formed by plastic deformation

    Goyal, Amit

    2001-01-01

    A method of preparing a biaxially textured article comprises the steps of providing a metal preform, coating or laminating the preform with a metal layer, deforming the layer to a sufficient degree, and rapidly recrystallizing the layer to produce a biaxial texture. A superconducting epitaxial layer may then be deposited on the biaxial texture. In some embodiments the article further comprises buffer layers, electromagnetic devices or electro-optical devices.

  13. Linked Ocean Data

    Leadbetter, Adam; Arko, Robert; Chandler, Cynthia; Shepherd, Adam

    2014-05-01

    "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

  14. Database citation in full text biomedical articles.

    Kafkas, Şenay; Kim, Jee-Hyub; McEntyre, Johanna R

    2013-01-01

    Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are structured cross-references at the level of individual articles and biological records. Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

  15. Tracking Multiple Topics for Finding Interesting Articles

    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.

    2009-05-01

    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.

  17. FormLink/FeynCalcFormLink : Embedding FORM in Mathematica and FeynCalc

    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...

  2. [How to write an article: formal aspects].

    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.

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

    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.

  4. Characteristics and production of compound powder articles

    Characteristics of production of compound powder articles have been studied. It is shown that parts made from powder can be joined when heating using the 'growth' effect of pressed parts during sintering due to austenite-carbide alloy introduction into composition of the insent. Joining of parts is very strong if the structure of the jouning zone is similar to that of the basic material. It is reached by formation of grains common to joined materials due to the boundary migration induced either by primary or secondary recrystallization. The production parameters, temperature, sintering time, amount of the introduced addition, are ascertained to affect the joining strength. Properties of sintered materials based on iron are studied as affected by the process of complex thermodiffusion alloying. Mechanical properties, corrosion and scale resistance are determined in sintered articles with diffusion coatings. Saturation with chromium, nickel and silicon is shown to increase essentially mechanical-and-physical properties of sintered articles. (author)

  5. Altmetric: Top 50 dental articles in 2014.

    Kolahi, J; Khazaei, S

    2016-06-10

    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.

    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.

  15. Helically linked mirror arrangement

    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

  6. Method for welding an article and terminating the weldment within the perimeter of the article

    Smashey, Russell W. (Inventor); Snyder, John H. (Inventor); Boerger, Eric J. (Inventor); Borne, Bruce L. (Inventor)

    2000-01-01

    An article is welded, as in weld repair of a defect, by positioning a weld lift-off block at a location on the surface of the article adjacent to the intended location of the end of the weldment on the surface of the article. The weld lift-off block has a wedge shape including a base contacting the surface of the article, and an upper face angled upwardly from the base from a base leading edge. A weld pool is formed on the surface of the article by directly heating the surface of the article using a heat source. The heat source is moved relative to the surface of the article and onto the upper surface of the weld lift-off block by crossing the leading edge of the wedge, without discontinuing the direct heating of the article by the heat source. The heating of the article with the heat source is discontinued only after the heat source is directly heating the upper face of the weld lift-off block, and not the article.

  7. Problem Formulation and Analysis of the 1-Hop ARQ Links

    Cheung, K.-M.

    2013-08-01

    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 reexamined. In this article, we provide the problem formulation and extend the standard link analysis approach to a 1-hop ARQ link (no routing), under the assumption that code-block errors occur independently as in the case of space communications. We develop analytical models that describe the statistical behavior of standard 1-hop ARQ links. By integrating these analytical ARQ protocol models into the standard link analysis, we bypass the need to simulate or emulate the ARQ protocol operations, and generate relevant statistics on effective data rate, effective throughput, latency, and FER.

  8. Volumes of chain links

    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|.

Endogenous growth theory does not explain how or why spillovers occur. The missing link is the mechanism converting knowledge into economically relevant knowledge. This paper develops a model that introduces a filter between knowledge and economic knowledge and identifies entrepreneurshi...

  10. WEAK LINKS AND DIVERSIFICATION

    Cristian Ugarte

    2014-01-01

    An important literature has shown that the relationship between economic diversification and income per capita is non-monotonic (Imbs and Wacziarg, 2003 and Koren and Tenreyro, 2007). At early stages of development countries diversify as income increases and new economic opportunities emerge, but at later stages of development the production bundle becomes more concentrated as income rises. The aim of this paper is to explore the role played by Weak Links effects à la Jones (2011) in explaini...

  11. Siemens SOFC Test Article and Module Design

    None

    2011-03-31

    Preliminary design studies of the 95 kWe-class SOFC test article continue resulting in a stack architecture of that is 1/3 of 250 kWe-class SOFC advanced module. The 95 kWeclass test article is envisioned to house 20 bundles (eight cells per bundle) of Delta8 cells with an active length of 100 cm. Significant progress was made in the conceptual design of the internal recirculation loop. Flow analyses were initiated in order to optimize the bundle row length for the 250 kWeclass advanced module. A preferred stack configuration based on acceptable flow and thermal distributions was identified. Potential module design and analysis issues associated with pressurized operation were identified.

  12. Online medical journal article layout analysis

    Zou, Jie; Le, Daniel; Thoma, George R.

    2007-01-01

    We describe a physical and logical layout analysis algorithm, which is applied to segment and label online medical journal articles (regular HTML and PDF-Converted-HTML files). For these articles, the geometric layout of the Web page is the most important cue for physical layout analysis. The key to physical layout analysis is then to render the HTML file in a Web browser, so that the visual information in zones (composed of one or a set of HTML DOM nodes), especially their relative position, can be utilized. The recursive X-Y cut algorithm is adopted to construct a hierarchical zone tree structure. In logical layout analysis, both geometric and linguistic features are used. The HTML documents are modeled by a Hidden Markov Model with 16 states, and the Viterbi algorithm is then used to find the optimal label sequence, concluding the logical layout analysis.

  16. Revisiting Summarization Evaluation for Scientific Articles

    Cohan, Arman; Goharian, Nazli

    2016-01-01

    Evaluation of text summarization approaches have been mostly based on metrics that measure similarities of system generated summaries with a set of human written gold-standard summaries. The most widely used metric in summarization evaluation has been the ROUGE family. ROUGE solely relies on lexical overlaps between the terms and phrases in the sentences; therefore, in cases of terminology variations and paraphrasing, ROUGE is not as effective. Scientific article summarization is one such cas...

  2. On Academic Conflict in Medical Research Articles

    ZHANG Xiao-mei; CHEN Ning; NIE Wen-xin

    2013-01-01

    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.

  3. Connecting every bit of knowledge: The structure of Wikipedia's First Link Network

    Ibrahim, Mark; Dodds, Peter Sheridan

    2016-01-01

    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...

  6. Deconstructing English Articles A Construction Grammar Approach To Teaching Articles In English

    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.

  7. Links demystified: Periodontitis and cancer

    Gowri Pendyala

    2013-01-01

    Full Text Available Cancer is marked by the uncontrolled growth of cells, tissue invasion and metastasis to various organs via the circulatory and lymphatic systems. Recent data have expanded the concept that inflammation is a critical component of tumor progression. Many cancers arise from sites of infection, chronic irritation, and inflammation. The tumor microenvironment, which is largely orchestrated by inflammatory cells, is an indispensable participant in the neoplastic process, fostering proliferation, survival, and migration. Periodontal disease, a chronic inflammatory condition is characterized by an oral bacterial infection leading to inflammation within the supporting tissues of the teeth, which often leads to the destruction of the periodontal tissues and alveolar bone that support the teeth. This oral inflammation often has systemic effects leading to an increased concentration of circulating inflammatory markers with the severity of disease being correlated directly with levels of serum inflammatory markers. Periodontal infection has been linked to organ and systemic diseases. There is documented evidence of significant associations between cancer of the lung, kidney, pancreas, hematological and oral cancers, and periodontal disease. This articles reviews and summarizes the possible biological mechanisms involved between periodontal infection and cancer.

    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. In this article we present a short review of recent activities in this area.

    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 sy...

  16. Process of producing a ceramic matrix composite article and article formed thereby

    Corman, Gregory Scot; McGuigan, Henry Charles; Brun, Milivoj Konstantin

    2011-10-25

    A CMC article and process for producing the article to have a layer on its surface that protects a reinforcement material within the article from damage. The method entails providing a body containing a ceramic reinforcement material in a matrix material that contains a precursor of a ceramic matrix material. A fraction of the reinforcement material is present and possibly exposed at a surface of the body. The body surface is then provided with a surface layer formed of a slurry containing a particulate material but lacking the reinforcement material of the body. The body and surface layer are heated to form the article by converting the precursor within the body to form the ceramic matrix material in which the reinforcement material is contained, and by converting the surface layer to form the protective layer that covers any fraction of the reinforcement material exposed at the body surface.

  2. Percolation on networks with dependence links

    As a classical model of statistical physics, the percolation theory provides a powerful approach to analyze the network structure and dynamics. Recently, to model the relations among interacting agents beyond the connection of the networked system, the concept of dependence link is proposed to represent the dependence relationship of agents. These studies suggest that the percolation properties of these networks differ greatly from those of the ordinary networks. In particular, unlike the well known continuous transition on the ordinary networks, the percolation transitions on these networks are discontinuous. Moreover, these networks are more fragile for a broader degree distribution, which is opposite to the famous results for the ordinary networks. In this article, we give a summary of the theoretical approaches to study the percolation process on networks with inter- and inner-dependence links, and review the recent advances in this field, focusing on the topology and robustness of such networks.

  3. The Bibliometric Properties of Article Readership Information

    Kurtz, Michael J; Accomazzi, Alberto; Grant, Carolyn S; Demleitner, Markus; Murray, Stephen S; Martimbeau, Nathalie; Elwell, Barbara

    2009-01-01

    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...

The superconducting layer has an as-formed critical current I.sub.C(AF) and a post-stabilized critical current I.sub.C(PS). The I.sub.C(PS) is at least about 95% of the I.sub.C(AF).

  6. The Language of Islamophobia in Internet Articles

    Haja Mohideen

    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.

  7. Rupture of pectoralis major muscle: review article

    Guity MR

    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.

  8. Link Analysis for Space Communication Links Using ARQ Protocol

    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.

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

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

    2016-01-01

    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. PMID:26961965

    This article generalizes our previous results for a quantum system of two nodes to a quantum system ofm(m ≥ 2) nodes. It shows that there is a one to one correspondence between 2m GHZ states for a quantum system ofm(m ≥ 2) nodes and 2m oriented links of the linkage N1 in knot theory, where N = 4 C2m = 2m(m - 1) is the numberof crossings of the link with m components, the subscript 1 denotes the order of the unoriented m components link withN crossings, i.e. the first type, actually the simplest type.

  12. Lymphangiosarcoma of dogs : a review : review article

    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.

  14. Exploring the evidence in pediatric hematology and oncology nursing through the "article of the month".

    Linder, Lauri

    2010-01-01

    As the scope of pediatric hematology and oncology nursing expands, nurses are challenged with staying current in the evidence guiding their practice. Nurse-reported barriers to accessing and utilizing research include lack of time as well as difficulty in accessing, understanding, and synthesizing findings. Journal clubs provide a process to guide nurses in the review of current literature related to their practice and promote utilization of research and evidence-based practice among nurses. This article describes the transition of an in-person journal club to an electronically delivered "Article of the Month." The "Article of the Month" is offered six times each year and is posted on the service line's password-protected intranet website. Oversight of the "Article of the Month" is provided by the service line clinical nurse specialist who selects articles based on an annual learning needs assessment and develops a quiz to assess learning and promote critical thinking among nursing staff. Outcomes include anecdotal reports of increased staff confidence in managing emergent patient care needs and greater appreciation of nursing care issues for children with cancer. Areas for future development include exploring options for increasing in-person discussion of issues addressed in the "Article of the Month" among staff members, extending the "Article of the Month" to nurses in other service areas who care for children with cancer, and increasing staff participation in article selection and quiz item development. An ultimate goal is to develop formal evaluation strategies to link this educational strategy to clinical outcomes. PMID:20038673

  15. Featured Article: Genotation: Actionable knowledge for the scientific reader.

    Nagahawatte, Panduka; Willis, Ethan; Sakauye, Mark; Jose, Rony; Chen, Hao; Davis, Robert L

    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.

  16. The Bibliometric Properties of Article Readership Information

    Kurtz, Michael J.; Eichhorn, Guenther; Accomazzi, Alberto; Grant, Carolyn S.; Demleitner, Markus; Murray, Stephen S.; Martimbeau, Nathalie; Elwell, Barbara

    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 \\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

    pLink is a search engine for high-throughput identification of cross-linked peptides from their tandem mass spectra, which is the data-analysis step in chemical cross-linking of proteins coupled with mass spectrometry analysis. pLink has accumulated more than 200 registered users from all over the world since its first release in 2012. After 2 years of continual development, a new version of pLink has been released, which is at least 40 times faster, more versatile, and more user-friendly. Also, the function of the new pLink has been expanded to identifying endogenous protein cross-linking sites such as disulfide bonds and SUMO (Small Ubiquitin-like MOdifier) modification sites. Integrated into the new version are two accessory tools: pLabel, to annotate spectra of cross-linked peptides for visual inspection and publication, and pConfig, to assist users in setting up search parameters. Here, we provide detailed guidance on running a database search for identification of protein cross-links using the 2014 version of pLink. PMID:25754995

  20. FANTM, the First Article NIF Test Module

    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

    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 ceramic matrix composite article and a process of fabricating a ceramic matrix composite are disclosed. The ceramic matrix composite article includes a matrix distribution pattern formed by a manifold and ceramic matrix composite plies laid up on the matrix distribution pattern, includes the manifold, or a combination thereof. The manifold includes one or more matrix distribution channels operably connected to a delivery interface, the delivery interface configured for providing matrix material to one or more of the ceramic matrix composite plies. The process includes providing the manifold, forming the matrix distribution pattern by transporting the matrix material through the manifold, and contacting the ceramic matrix composite plies with the matrix material.

  5. Innovations in structuring article introductions: The case of Applied Linguistics

    Ling Lin

    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

  7. The CMS link system

    The Compact Muon Solenoid (CMS) is a multi-purpose detector that is going to be installed in the future Large Hadron Collider (LHC) at CERN. Muons are one of the main physical signatures of the expected new physics. The muons are going to be detected by the Central Tracker (CT) and the Muon Spectrometer (MS). Both, the CT and MS can provide an independent muon momentum measurement, but for all η and momentum values the highest precision for muon momentum measurement is achieved when the muon tracks are reconstructed using both tracking detectors. The calorimeters and the solenoid volumes separate about three meters the CT and the MS. It has been shown that the alignment of the CT with respect to the MS can not be guaranteed by a software alignment in a reasonable time scale. Therefore, an opto-mechanical system (the multipoint link system) have been designed to monitor, on-line, the relative position of both sub-detectors providing a common reference frame for both of them. The local alignment of the muon barrel spectrometer determines the relative position of the muon chambers with respect to themselves and also with respect to a carbon fiber rigid structure called MAB (Module for the Alignment of the Barrel). There are a total of 36 MABs distributed in the boundary planes of each muon spectrometer sector. This paper describes all the equipment and presents the principle of measurement. (author)

  8. 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.

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

    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)

  11. Improving Linking from the Literature to On-line Data

    Eichhorn, G.; Accomazzi, A.; Grant, C. S.; Henneken, E. A.; Kurtz, M. J.; Murray, S. S.

    2003-12-01

    The ADS, in close collaboration with the Astrophysics Data Centers Executive Committee (ADEC) and the American Astronomical Society (AAS) has been working on improving the linking between the literature and on-line data by allowing authors to specify data that were used in the research described in journal articles. We are working with the ADEC on identifying data sets in a consistent manner. The ADEC has agreed that all NASA data centers will use data set identifiers of the form: ADS/facility#identifier where facility specifies the telescope that acquired the data and identifier is a data center selected identifier for a particular data set. The ADS is providing a registration service for facility names that identify data collections at the various data centers, a verification service that allows authors and editors to verify the existence of data set identifiers, and a linking service that allows journals to use permanent URLs for links to data sets that may move between data centers. Current plans of the ADEC-AAS collaboration call for including data set identifiers in the LaTeX manuscripts by the authors. The data set identifiers will be provided by the data centers with all data delivered. The editorial process will verify all data set identifiers and include links to the on-line data from the on-line articles. The identifiers used in each article will be made available to the ADS for linking to the on-line data from the ADS system as well.

  13. Linking ecosystem processes to sustainable wetland management

    Euliss, Ned H.; Smith, Loren M.; Wilcox, Douglas A.; Browne, Bryant A.

    2009-01-01

    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 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 ...

    Liu, Zhu; Tang, Chun

    2016-06-01

    The data described herein are related to the article entitled "Lys63-linked ubiquitin chain adopts multiple conformational states for specific target recognition" [1], and to the coordinates for the ensemble structure of Lys63-linked diubiquitin (PDB code 2N2K). A Lys63-linked diubiquitin exists in three conformational states with different orientations for the two subunits, each responsible for binding to a target protein and encoding a specific cell signal. An atomic entry in the ensemble structure file consists multiple lines, representing alternative locations of the atom and recapitulating the dynamics of the protein. Experimental details about obtaining strictly intramolecular paramagnetic restraints and determining the relative occupancies of the conformational states are presented. The experimental design and procedures in this Data article can be useful for characterizing the structure and dynamics of other multi-domain proteins. PMID:26955652

  20. Divestiture: strategy's missing link.

    Dranikoff, Lee; Koller, Tim; Schneider, Antoon

    2002-05-01

    Although most companies dedicate considerable time and attention to acquiring and creating businesses, few devote much effort to divestitures. But regularly divesting businesses--even good, healthy ones--ensures that remaining units reach their potential and that the overall company grows stronger. Drawing on extensive research into corporate performance over the last decade, McKinsey consultants Lee Dranikoff, Tim Koller, and Antoon Schneider show that an active divestiture strategy is essential to a corporation's long-term health and profitability. In particular, they say that companies that actively manage their businesses through acquisitions and divestitures create substantially more shareholder value than those that passively hold on to their businesses. Therefore, companies should avoid making divestitures only in response to pressure and instead make them part of a well-thought-out strategy. This article presents a five-step process for doing just that: prepare the organization, identify the best candidates for divestiture, execute the best deal, communicate the decision, and create new businesses. As the fifth step suggests, divestiture is not an end in itself. Rather, it is a means to a larger end: building a company that can grow and prosper over the long haul. Wise executives divest so that they can create new businesses and expand existing ones. All of the funds, management time, and support-function capacity that a divestiture frees up should therefore be reinvested in creating shareholder value. In some cases, this will mean returning money to shareholders. But more likely than not, it will mean investing in attractive growth opportunities. In companies as in the marketplace, creation and destruction go hand in hand; neither flourishes without the other. PMID:12024760
