The purpose was to compare children with and without learning disabilities (LD), ages 6–8 years, on midline crossing inhibition (MCI). Participants were 44 children (24 boys and 20 girls) in two groups (LD and non-LD), matched on age and gender. MCI was operationally defined as significantly slower contralateral movement when choice reaction time (CRT) and movement time (MT) performance were examined for ipsilateral, midline, and contralateral tasks with both upper and lower extremities. Participants completed 12 days of tests (30 trials each day) using a protocol developed by Eason and Surburg (1993). A 2 (Group) × 2 (Extremity) × 3 (Direction) repeated measures MANOVA revealed significant difference for each dependent variable. Children with LD displayed MCI, whereas children without LD did not.

Introduction: These changes are the main causes of defi cits in perceptual-motor skills responsible for motor skill acquisition and performance of functional activities. AIMS: The current study aimed at verifying the quantitative performance of people with DS in undertaking a computer task to compare the performances of typical development (TD). Method: 60 subjects participated in the study, 30 with Down’s syndrome and 30 with typical development, matched by sex. Individuals were aged from 10–36. The groups were divided into three subgroups by age: Group 1 (G1) 10–18; Group 2 (G2) 18–25; Group 3 (G3) 25–36. They performed a computer maze task. During the acquisition phase all groups attempted the maze 30 times, and then after 5 minutes they performed 5 repetitions of Maze 1 for the retention phase. Finally, for the transfer phase, they performed fi ve repetitions in Maze 2. The dependent variables were submitted to a group, age group, gender and block ANOVA with repeated measures on the last factor. Results: In acquisition phase there was a significant decrease in movement time (MT) between the fi rst and last acquisition block, but only for the DS-group. In retention, there was a significant effect of Group, and an interaction between Block and Group, indicating that MTs increased from retention to transfer, but only for the DS-group. Conclusion: It was found that participants with DS improved performance during acquisition and retention, but they had diffi culty in performing the transfer of the computational task for a similar situation. The age and gender were not signifi cant in any of the stages of the study.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

AbstractIt is unknown how self-relevance is dependent on emotional salience. Emotional salience encompasses an individual's degree of attraction or aversion to emotionally-valenced information. The current study investigated the interconnection between self and salience through the evaluation of emotional valence and self-relevance. 56 native Dutch participants completed a questionnaire assessing valence, intensity, and self-relevance of 552 Dutch nouns and verbs. One-way repeated-measures ANCOVA investigated the relationship between valence and self, age and gender. Repeated-measures ANCOVA also tested the relationship between valence and self with intensity ratings and effects of gender and age. Results showed a significant main effect of valence for self-relevant words. Intensity analyses showed a main effect of valence but not of self-relevance. There were no significant effects of gender and age. The most important finding presents that self-relevance is dependent on valence. These findings concerning the relationship between self and salience opens avenues to study an individual's self-definition.

Objective(s). The purpose of this study was to explore the effectiveness of wideband acoustic immittance (WAI) in the diagnosis of otosclerosis by comparing the differences in the energy reflectance (ER) of WAI between patients with otosclerosis and age- and gender-matched normal hearing controls in the Chinese population. Methods. Twenty surgically confirmed otosclerotic ears were included in the otosclerotic group. The ER of WAI at ambient and peak pressures, resonance frequency, and 226-Hz tympanogram were collected prior to surgery using a Titan hearing test platform (Interacoustics A/S, Middelfart, Denmark). All diagnoses of otosclerosis in the tested ear were confirmed by surgery after the measurements. Thirteen normal adults (26 ears) who were age- and gender-matched with the otosclerotic patients were included as the control group. Results. At peak pressure, the ERs of otosclerotic patients were higher than those of the control group for frequencies less than 4,000Hz and were lower for frequencies greater than 4,000Hz. In addition, within the analyzed frequencies, the differences observed at 2,520Hz was statistically significant (p<0.05/16=0.003, Bonferroni corrected). At ambient pressure, the differences observed at 1,260 and 6,350Hz were statistically significant (p<0.05/16=0.003, Bonferroni corrected). Although the differences between the otosclerotic and control groups exhibited similar trends to those in studies implemented in Caucasian populations, the norms in the present study in the control group were different from those in the Caucasian populations, suggesting racial differences in WAI test results. Regarding the middle ear resonance frequency, no significant difference was observed between the two groups (P>0.05). Conclusion. WAI can provide valuable information for the diagnosis of otosclerosis in the Chinese population. Norms and diagnostic criteria corresponding to the patient’s racial group are necessary to improve the efficiency of WAI in the diagnosis of otosclerosis.

Abstract Objective To measure the level of hair Mg, as well as its level in serum, in patients with epilepsy and compare them to the levels found in non-epileptic age and gender matched children, and to explore any potential correlation between either serum or hair level of magnesium and seizure characteristics in children with idiopathic epilepsy. Methods An observational cross-sectional study including 50 children with idiopathic epilepsy and 100 non-epileptic age and gender matched control subjects. Cases were subjected to full history taking, examination and measurements of serum and hair levels of magnesium, control subjects only had their serum and hair level of magnesium measured as for the cases. Results The mean serum magnesium was 29.11 ± 13.42 ug/ml for cases and 27.67 ± 7.24 ug/ml for controls and the median hair level of magnesium was 42.22 ug/g with IQR of 25.9 - 56.82 for cases and 38.6 ug/g with IQR of 25.21 - 61.25 for controls. No statistically significant difference was observed between both groups as regards either serum or hair magnesium levels. No statistically significant correlation was observed between either hair or serum levels of magnesium and seizure characteristics though the correlations were nearing statistical significance for the hair magnesium content. Conclusion Hair magnesium level may be better correlated to seizure characteristics and control than serum levels in patients with epilepsy.

Background : Fibromyalgia syndrome (FMS) is defined as widespread and persistent pain in the musculoskeletal system. There are limited reports regarding the prevalence of fibromyalgia syndrome in patients with advanced kidney failure undergoing regular hemodialysis. Therefore, this study aimed to evaluate the prevalence of fibromyalgia syndrome and its risk factors in a large proportion of patients under the hemodialysis condition. Materials and Methods: In this cross-sectional study, 293 patients who were admitted to the hemodialysis ward were evaluated for fibromyalgia syndrome in an educational hospital. The questionnaire was designed according to symptom severity score (SS score) and widespread pain index (WPI) criteria. The correlation between FMS and various variables, including demographic, clinical, and biochemistry biomarkers, was also precisely calculated by logistic regression. Data were analyzed using SPSS v.17 statistics software. Results: The results showed that, of 293 hemodialysis patients, 130 patients (44.4%) had fibromyalgia, the mean age of patients with and without fibromyalgia was 61.09 ± 15.36 and 53.49 ± 15.38 years old, respectively (P = 0.001). Moreover, there was a significant difference in terms of gender among patients with fibromyalgia syndrome (P = 0.001). To note, there was no significant relationship between the kidney failure etiopathogenesis, duration of dialysis, body mass index (BMI), Kt/v index, history of peritoneal dialysis, and laboratory parameters with fibromyalgia in hemodialysis patients (P > 0.05). However, our findings revealed that both age and gender could be considered as the predictor variables associated with fibromyalgia in patients undergoing hemodialysis. Conclusion: Taken together, in this study, we found that age and gender would be the critical factors in terms of the fibromyalgia syndrome in patients undergoing hemodialysis.

<p>This study was conducted to compare with the executive function of ADHD versus normal male and female children. To obtain this objective, 30 ADHD children referring a private psychological center for the first time who had taken no medication for this disorder, and 30 normal children from one of the schools of District 14 in Tehran were selected randomly who were of the same age and gender of ADHD children. Wisconsin test was used as a measurement tool. Results showed that there is a significant difference between the average scores of the executive function of normal and ADHD children as well as average scores of the executive function of normal boys and ADHD children at the 0.01 level. In addition, there was a significant difference between the average scores of the executive function of normal girls and ADHD girls at the 0.05 level according to which null hypothesis is rejected. Therefore, ADHD children are of lower executive and cognitive function compared to normal children and have extensive cognitive deficits. Therefore, they require medications along with special training and rehabilitation.</p>

Background: The rib cage, such as the thoracic spine and ribs, influences glenohumeral mobility and the development of shoulder disorders. Objective: To evaluate movements of the ribs, thoracic vertebrae during bilateral arm elevation and to clarify the characteristic influences of age and gender. Methods: Subjects comprised 33 healthy individuals divided into a young group (10 males, 7 females; mean age, 25 years) and a middle-aged group (8 males, 8 females; mean age, 52 years). Chest CT was performed with two arm positions: arms hanging downwards; and arms elevated at 160°. Images were three-dimensionally reconstructed to evaluate rib movement, extension angle of thoracic vertebrae. Results: Maximal movement was observed at the fifth rib, and rib movement decreased with increasing distance from the fifth rib in both the groups. In males, movement of the second to fourth ribs was smaller in the middle-aged group than in the young group (p < 0.05). Movement of the first to ninth ribs was smaller in females than in males (p < 0.05). No significant difference in the extension angle of the thoracic vertebrae was found. Conclusion: Fifth rib movement is the largest among all ribs during bilateral arm elevation. Reduction of upper rib movement initially arises as an age-related degradation in males. Women exhibit less rib movement during bilateral arm elevation.

Colorectal cancer has became burden in the world.The latest study shows that colorectal cancer is the third most common cancer in men and second most common cancer in women globally. There are difference characteristic of epidemiology in every countries. Moreover, there is no study that represents epidemiology of colorectal cancer in Indonesia yet, especially in East Java. The aim of this study was to describe colorectal tumor profile by age and gender in Gastroentero-Hepatology Center, Dr Soetomo Hospital. This study has received a certificate of Ethical Clearance No.273/Panke.KKE/IV/2015, a descriptive retrospective study. We collected data using medical records, and patients who have been colonoscopy examination and suspected colorectal tumor were included. There were 201 patients, divided to 100 males and 101 females. The peak of incidence was on 51-60 years old group, but on the 31-40 years old incidence of colorectal tumor was increased. The youngest patient was 17 years old. And tumors are more likely develop in distal area, especially in rectum. This study shows a different characteristic profile of colorectal tumor, where tumor is developed at young people and there is no significant difference between male and female for the incidence.

The purpose of the study is to examine the pedagogical usability of interactive e-learning materials for foreign language practice. It is based upon two studies of the expected between-group and within-group differences among participants in the educational process. The sample consists of two groups – lecturers and students, a total of 100 participants, each evaluating four materials specifically prepared for this study. Two consecutive repeated measures ANOVA were conducted in which the gender/age, the position of the participants in the educational process, and usability dimensions were the independent variables. Results indicated that all independent variables and their interactions have a significant effects on the evaluations of the pedagogical usability. Women tend to assign higher values than men. Аge groups generally differ in their evaluations, although there is a tendency to give similar ratings for the individual dimensions of pedagogical usability. The 31-40 years age group evaluates the materials higher while the lowest evaluations are given by the groups of 21-30 and 50+ year old participants. Students tend to rate the pedagogical usability systemically higher than the lecturers. Usability dimensions also have a significant effect on evaluations. The most prominent feature of the materials, by a great margin, is their Applicability. The findings corroborate previous research which show age and gender differences in web usability do exist. We conclude that these differences exist as much in pedagogical usability as in technical usability. Further investigations are suggested to explore more deeply the differences in the perceived pedagogical value of e-learning materials as this has implications for instructional designers, teachers and learners alike.
