Perceptions of the Professionals and Parents of Children with Autism Spectrum Disorders About Autism Services; A Qualitative Study.

In this qualitative study, we aimed to explore the challenges of providing services and supports for children with autism spectrum disorders (ASD) and their families from the perceptions of professionals and parents of children with ASD. We classified the results of the study into three key categories including shortcomings in the management of children with ASD; shortcomings of supportive programs and facilities for children with ASD and their families; and organizational challenges in providing services for these children. We analyzed data using the content analysis method.

Effect of nanoclay orientation on oxygen barrier properties of LbL nanocomposite coated films.

Layer by layer (LbL) film deposition is an efficient technique used to produce thin coatings with high gas barrier properties. In this study, multilayer composite coatings with hydrogen bonding inter-layer interactions were deposited by LbL on a PET substrate, with an alternate deposition of a nanoclay layer and different intercalating polymers layers, namely chitosan (CS), polyethylene oxide (PEO), polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA). The investigated coatings had two different structures, quadlayers and bilayers which are different in the number of layers in the repetitive unit (four and two respectively).

Central ameloblastoma with a peripheral ameloblastoma-like component: a case report.

Amebloblastoma as the most common epithelial odontogenic neoplasm may occur in two forms of central and peripheral. This report presents a case of a 41-year-old Iranian female with a six-month complaint from a painless mass in the right posterior portion of the mandible. The case was diagnosed as an exophytic epulis-like peripheral component with characteristics of peripheral ameloblastoma and an intrabony component like solid ameloblastoma.
