I Read I Play: A Web Based Application for Supporting Children's Learning Process
AbstractIn latest years, there is a consisting trend in creating increasingly rich educational opportunities involving for children. Epistemology and technology act for an important set to determine innovative educational materials. Computers can engender a bridge over the educational distances for every child. Realizing a demand, a Web-based application has been developed with a creative reading approach in order to improve the child's reading-comprehension, narrative skills involving activities such as reading, writing, visual reading, relating, comprehension, criticizing, estimation and playing educational computer games. This study aims to offer to children many learning benefits such as motivation, engagement and fun in addition to providing many skills for instance logical thinking and problem solving as well as understanding of abstract concepts. This paper focuses on sharing implementation experiences of our application that expand a positive attitude for reading in children
Heart Rate Variability in Children with Tricyclic Antidepressant Intoxication
The aim of this study was to evaluate HRV in children requiring intensive care unit stays due to TCA poisoning between March 2009 and July 2010. In the time-domain nonspectral evaluation, the SDNN (P<0.001), SDNNi (P<0.05), RMSDD (P<0.01), and pNN50 (P<0.01) were found to be significantly lower in the TCA intoxication group. The spectral analysis of the data recorded during the first 5 minutes after intensive care unit admission showed that the values of the nLF (P<0.05) and the LF/HF ratio (P=0.001) were significantly higher in the TCA intoxication group, while the nHF (P=0.001) values were significantly lower. The frequency-domain spectral analysis of the data recorded during the last 5 minutes showed a lower nHF (P=0.001) in the TCA intoxication group than in the controls, and the LF/HF ratio was significantly higher (P<0.05) in the intoxication group. The LF/HF ratio was higher in the seven children with seizures (P<0.001). These findings provided us with a starting point for the value of HRV analysis in determining the risk of arrhythmia and convulsion in TCA poisoning patients. HRV can be used as a noninvasive testing method in determining the treatment and prognosis of TCA poisoning patients
Angiotensin IV improves spatial memory in streptozotocin-induced diabetic rats by reducing oxidative stress and altering BDNF levels
In this study, we investigated the protective effects of angiotensin IV (Mg IV) on cognitive function in streptozotocin (STZ)-induced diabetic rats. Male Wistar albino rats, were randomly divided into four groups; control (C), diabetes (Dia, 60 mg/kg, STZ, i.p.), Mg IV (5 mu g/kg, s.c.) and Dia+Ang W. The passive avoidance and Morris water maze (MWM) tests were used to evaluate learning and memory performance. Behavioral tests were carried out between 21 and 30 days after the initial Ang IV injection. Hippocampi were dissected and retained for biochemical and Western blot analysis. The Dia group exhibited the poorest behavioral results, while the Dia+Ang W group performed highest on the MWM task. Superoxide dismutase, glutathione peroxidase, and malondialdehyde levels increased significantly in the Dia group compared to Dia+Ang IV. Brain-derived neurotrophic factor (BDNF) and N-methyl-D-aspartate levels were significantly elevated, while levels of GABA(A) significantly decreased, in the Dia+Ang IV group compared to the Dia group. These findings suggest that peripheral administration of Ang IV ameliorated spatial memory in diabetic rats by decreasing hippocampal oxidative stress and BDNF levels

Early Morphological Development and Allometric Growth Patterns in Hatchery-Reared Red Porgy (Pagrus pagrus)
WOS: 000348290200024Morphological development and allometric growth were investigated in the red porgy, Pagrus pagrus, during larval development until the end of weaning at 46 days after hatching (DAH). Total length (TL) of newly hatched larvae was 2.77 +/- 0.09 mm (mean +/- SE). Onset of exogenous feeding occurred at 4 DAH (3.74 +/- 0.13 mm TL). Initial swimbladder inflation occured at 10 DAH (4.22 +/- 0.18 mm TL) and post-inflation became more elongate at 16 DAH (4.95 +/- 0.26 mm TL). Notochord flexion occurred between 22 DAH (5.56 +/- 0.43 mm TL) and 34 DAH (8.22 +/- 0.63 mm TL). At the end of the weaning at 46 DAH, TL of larvae was 15.81 +/- 1.36 mm According to individual measurements of a total of 1026 larvae of 18 body parameters for allometric growth, in 19 of 35 respective regression equations, the allometry coefficients were positive, while coefficients of 7 equations showed negative allometry. The majority of all allometric changes from inflection point were expressed during the larval stage and were integrated with the metamorphosis stage. Inflections in body proportion changes occurred mainly at TL values of 3.74, 4.22 and 5.56 mm, coinciding with mouth opening, initial swimbladder inflation and flexion of notochord, respectively
Apolipoprotein A5 polymorphisms in Turkish population: association with serum lipid profile and risk of ischemic stroke
Atherosclerosis, a major cause of ischemic stroke, may be associated with variability of triglyceride (TG) levels. Apolipoprotein A5 (APOA5) genetic polymorphisms are associated with altered TG levels. The objective of this study was to investigate the coding region polymorphisms S19W (rs3135506) and G185C (rs2075291) and the promoter region polymorphism -1131T > C (rs662799) of the APOA5 gene as risk factors for ischemic stroke in Turkish population. Study group consisted of 272 ischemic stroke patients and 123 controls. Genotypes were determined by real-time polymerase chain reaction (PCR) for S19W and PCR-restriction fragment length polymorphism analysis (PCR-RFLP) for -1131T > C and G185C. 19W allele frequency was 0.090 in stroke patients and 0.062 in controls (P = 0.191). Minor allele frequencies of -1131T > C and G185C in patients were 0.106 and 0.004, respectively, and were nearly the same in controls. Total cholesterol and LDL-cholesterol levels were significantly higher for stroke patients having at least one 19W allele compared to non-carriers. A significant difference was also found for LDL-cholesterol levels of stroke patients; higher in -1131C allele carriers compared to wild type patients. There was a trend for higher frequency of ischemic stroke among -1131C allele carrier hypertensive, diabetic or obese subjects compared to non-carriers. However, APOA5 genotypes were not associated with the risk of ischemic stroke by logistic regression analysis. The present study demonstrated that carrying rare alleles of APOA5 S19W, -1131T > C and G185C alone do not constitute a risk for ischemic stroke in the studied Turkish subjects
Cerebral Venous Sinus Thrombosis in Women: Subgroup Analysis of the VENOST Study
Background. Early diagnosis of cerebral venous sinus thrombosis (CVST) associated with reproductive health-related risk factors (RHRF) including pregnancy, puerperium, and oral contraceptive (OC) use can prevent severe neurological sequelae; thus, the symptoms must be documented in detail for each group.Methods. Out of 1144 patients with CVST, a total of 777 women were enrolled from a multicenter for the study of cerebral venous sinus thrombosis (VENOST). Demographic, biochemical, clinical, and radiological aspects were compared for 324 cases with RHRF and 453 cases without RHRF.Results. The mean age of the RHRF (-) group (43.2 +/- 13 years) was significantly higher than of the RHRF (+) group (34 +/- 9years). A previous history of deep venous thrombosis (3%), isolated cavernous sinus involvement (1%), cranial neuropathy (13%), comorbid malignancy (7%), and its disability scores after 12 months (9%) were significantly higher in the RHRF (-) group. The RHRF (+) group consisted of 44% cases of puerperium, 33% cases of OC users and 23% of pregnant women. The mean age was found to be higher in OC users (38 +/- 9years). A previous history of deep venous thrombosis was slightly higher in the pregnancy subgroup (4%). Epileptic seizures were more common in the puerperium group (44%).Conclusion. The results of our study indicate that the risk of CSVT increases parallel to age, OC use, and puerperium period. In addition, when considering the frequency of findings and symptoms, epileptic seizures in the puerperium subgroup of the RHRF (+) group and malignancies in the RHRF (-) group may accompany the CSVT. In daily practice, predicting these risks for the CSVT and early recognition of the symptoms will provide significant benefits to patients.WOS:0005704293000012-s2.0-85091439977PubMed: 3295303
The Effect of Education in Reducing Noise on Health Personnels' Knowledge Level and Behavioral Change
Objective: Noise must be reduced and taken under control because negatively affects the health of health personnel and preterm newborns in particular. The American Academy of Pediatrics reported that noise levels must be kept below 45 dB. However, many studies demonstrated that the desired level could not be reached. This research was conducted with the aim of evaluating the level of noise in a neonatal intensive care unit (NICU), and the effect of given education on controlling the noise
