The aim of this study was to explore the relationships between involvement in bullying behaviors and school, family, and peer factors. Health Behavior in School Age Children survey questionnaire was used. Of the students surveyed, 20% were both bully and victim, 11% were bully, and 21% were victim. Being male, poor parental support, and poor monitoring by the father were found to be risk factors for being both bully and victim. Poor academic achievement, having peers at different ages, poor quality of friendship, poor communication with parents, and not being isolated by peers were found to be risk factors for being bully. Not liking school, feeling pressured by school work, poor quality of friendship, poor monitoring by the father, close bonding with mother, and poor status of the peer group were found to be risk factors for being victim. These findings highlight the importance that bullying intervention programs should include country-specific and culture-specific influences for success.

Background/Aims: Osteoporosis-pseudoglioma (OPPG) syndrome is a rare disorder characterized by congenital or infancy-onset visual loss and severe juvenile osteoporosis. OPPG is caused by homozygous mutations in the low-density lipoprotein receptor-related protein 5 (LRP5) gene. We present three novel homozygous LRP5 mutations found in 3 unrelated Turkish children with consanguineous parents, along with clinical phenotypes and response to treatment with bisphosphonates (bisP). Methods/Results: The LRP5 gene was analyzed by direct sequencing after PCR amplification. Mutation screening for LRP5 revealed homozygous nonsense R1002X mutation in the first patient and homozygous missense mutations V336M and G507S in the second and third patient, respectively. The parents were heterozygous for these mutations. The patients’ eye symptoms began during the first months of life but the OPPG diagnoses were made based on skeletal deformities and osteopenia after 4 years of age. The patients’ bone mineral density Z scores were very low and consistent with osteopenia. All patients were treated with bisP for 3.5–7 years. Conclusion: We report three novel LRP5 mutations in 3 Turkish patients with OPPG. We show that the response of bisP therapy has improved the lumbar spinal bone mineral density Z scores and the patients’ quality of life as the bone pains decreased.

The aim of this research is to study and diagnose for the first time the Polaroid emulsion transfer in the contemporary artist Paolo Gioli’s artworks to provide preliminary knowledge about the materials of his artworks and the appropriate protocols which can be applied for future studies. The spectral analysis performed followed a multi-technical approach first on the mock-up samples created following Gioli’s technique and on one original artwork of Gioli, composed by: FORS (Fiber Optics Reflectance), Raman, and FTIR (Fourier-Transform InfraRed) spectroscopies. These techniques were chosen according to their completely non-invasiveness and no requirement for sample collection. The obtained spectra from FTIR were not sufficient to assign the dyes found in the transferred Polaroid emulsion. However, they provided significant information about the cellulose-based materials. The most diagnostic results were obtained from FORS for the determination of the dye developers present in the mock-up sample which was obtained from Polacolor Type 88 and from Paolo Gioli’s original artwork created with Polacolor type 89.
