A novel association of an uncommon pigmentation pattern: coexistence of cutis tricolor with intracranial teratoma and holoprosencephaly

Cutis tricolor was first described in a 17-year-old male patient by Happle et al. as a rare coexistence of circumscribed hyperpigmentation and hypopigmentation close to each other on a background of normally pigmented skin. Cutis tricolor has been reported as an isolated cutaneous finding or in various associations. To the best of our knowledge, cutis tricolor in association with teratoma and holoprosencephaly has not been reported in the literature. Herein, we report a male patient who presented with a teratoma and a combination of whorl-like hypopigmentation together with hyperpigmented patches adjacent to each other on intermediately pigmented skin. This case report supports the view that cutis tricolor may be a marker of an underlying neurological abnormality

Does Semantic Association Play a Role in Post-Event Misinformation Effect?

According to one of the most prominent false memory theories (Fuzzy Trace Theory), false memories stem from the semantic association between the original information and post-event misinformation. Furthermore, the strength of this association predicts the probability of accepting the post-event misinformation as original information. In order to test this prediction within the eyewitness testimony framework, the current study used a video of a mock-theft and a narrative of the event in which some original information was changed as post-event misinformation. To that end, the strong and the weak members of the category to which original information belongs to, and semantically unrelated options were given as distractors in addition to the original information in a recognition test. Analysis revealed that semantically strong and weak distractors were significantly more likely to be accepted as original information than the semantically unrelated item. Semantically strong distractors were accepted as original information more than weak distractors, although the difference did not reach significance. Findings were discussed in terms of Fuzzy Trace Theory and the "developmental reversals" approach by Brainerd and Reyna (2012)

A comparison of peptide amphiphile nanofiber macromolecular assembly strategies

Supramolecular peptide nanofibers that are composed of peptide amphiphile molecules have been widely used for many purposes from biomedical applications to energy conversion. The self-assembly mechanisms of these peptide nanofibers also provide convenient models for understanding the self-assembly mechanisms of various biological supramolecular systems; however, the current theoretical models that explain these mechanisms do not sufficiently explain the experimental results. In this study, we present a new way of modeling these nanofibers that better fits with the experimental data. Molecular dynamics simulations were applied to create model fibers using two different layer models and two different tilt angles. Strikingly, the fibers which were modeled to be tilting the peptide amphiphile molecules and/or tilting the plane were found to be more stable and consistent with the experiments

Novel adenosine deaminase 2 mutations in a child with a fatal vasculopathy

Adenosine deaminase 2 (ADA2) deficiency due to CECR1 mutations is a recently defined disorder that involves systemic inflammation and vasculopathy often associated with polyarteritis nodosa. We report on a 5-year-old girl with a severe vasculopathy who carried two novel mutations in CECR1. Conclusion: Identification of CECR1 mutations in patients with vasculopathy may lead to earlier diagnosis of ADA2 deficiency

Assessing the conformance of foods in school canteens in terms of health in Malatya a city of Turkey

A healthy diet for students is an important concept in terms of school health. In this regard, selling unhealthy foods in the school canteens causes a serious threat. With this study, we aimed to determine how well the Turkey Healthy Nutrition and Active Life Program with the number 201022 released by the Prime Ministers Office was applied at schools, and to reveal how reliable school canteens were in this context. This is a descriptive study. The sample size was calculated as 37 by considering the rate of chips sales in the school canteen as 2.65% with a power of 80% and a confidence level of 95%. Stratified sampling method was used to stratify the schools; after which 18 primary schools, 13 secondary schools and 6 high schools were selected. Statistic were expressed in numbers and percentages. It was observed that despite the prohibition, fruit-flavored beverages were sold in 51.4% of the schools included in the study, cokes were sold in 10.8% of the. Moreover, chips and french fries were present in the canteens in 18.9% and 8.1% of the included schools, respectively. Among the foods and drinks recommended in the circular, these school canteens had ayran (89.2%), milk (83.8%), yoghurt (18.9%), fresh fruits (8.1%) and fresh-squeezed fruitvegetable juices (5.4%). Although the sales of healthy beverages in the school canteens were high, the sales of unhealthy beverages were also high. The sales of yoghurt, fresh fruit and fresh-squeezed fruitvegetable juices were lower. Moreover, French fries and chips that should not be present in the canteens were also sold, which is thought-provoking. [Med-Science 2018; 7(2.000): 338-41

Factors revealed while posing mathematical modelling problems by mathematics student teachers

© 2018 Eurasian Society of Educational Research. All Rights Reserved.The purpose of this study is to reveal factors considered by mathematics student teachers while posing modelling problems. The participants were twenty-seven mathematics student teachers and posed their modelling problems within their groups. The data were obtained from the modelling problems posed by the participants, their solutions on these problems and the groups’ reflective diaries regarding their problem posing and solution processes. The data were analyzed by using content analysis and the codes were constructed according to the problems’ contents. The participants' diaries were examined in terms of generated codes and the expressions supporting/relating the codes were determined. While designing the problems, the participants considered the factors such as being interesting, understandable, appropriateness to real life and modelling process, model construction, and usability of different mathematical concepts. Their solutions were generally handled in terms of usage of the mathematical statements, appropriateness to the modelling process and being meaningful for real life. Modelling training should be provided to enable the student teachers to develop modelling problems and their designs should be examined and the feedbacks should be given
