Oxidative Stress in Autism Spectrum Disorder.

According to the United States Centers for Disease Control and Prevention (CDC), as of July 11, 2016, the reported average incidence of children diagnosed with an autism spectrum disorder (ASD) was 1 in 68 (1.46%) among 8-year-old children born in 2004 and living within the 11 monitoring sites' surveillance areas in the United States of America (USA) in 2012. ASD is a multifaceted neurodevelopmental disorder that is also considered a hidden disability, as, for the most part; there are no apparent morphological differences between children with ASD and typically developing children.

Solid state synthesis of docosahexaenoic acid-loaded zinc oxide nanoparticles as a potential antidiabetic agent in rats.

Our goal in this study is to improve the efficiency of docosahexaenoic acid (DHA) toward the enhancement of insulin signaling pathway in vivo via loading with zinc oxide nanoparticles (ZnO NPs). To this end, two consecutive steps were undertaken, preparation of ZnO NPs by one-step solid-state reaction in dry conditions and calcinated followed by loading DHA. Both developed nanoparticles, with and without DHA were then characterized by TEM, SEM, EDX, and Zetasizer.

Diagnostic and Severity-Tracking Biomarkers for Autism Spectrum Disorder.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder afflicting about one in every 68 children. It is behaviorally diagnosed based on a triad of symptoms, including impairment in communication, impairment in sociability and abnormal and stereotypic behavior. The subjectivity of behavioral diagnosis urges the need for clinical biomarker tests to improve and complement ASD diagnosis and treatment.

Altered urinary porphyrins and mercury exposure as biomarkers for autism severity in Egyptian children with autism spectrum disorder.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects social, communication, and behavioral development. Recent evidence supported but also questioned the hypothetical role of compounds containing mercury (Hg) as contributors to the development of ASD. Specific alterations in the urinary excretion of porphyrin-containing ring catabolites have been associated with exposure to Hg in ASD patients.
