Early onset and increasing disparities in neurodevelopmental delays from birth to age 6 in children from low socioeconomic backgrounds.

Objective: To analyze the complex relationship between socioeconomic status (SES) and neurodevelopmental achievements by investigating the temporal dynamics of these associations from birth to age 6.

Methods: This retrospective cohort study was conducted over 6 years using population-based data from the National Health Insurance Service and integrated data from the National Health Screening Program for Infants and Children. Participants were children born between 2009 and 2011 in Korea without neurodevelopmental delays with potential developmental implications.

Transient Isolated Lower Bulbar Palsy With Elevated Serum Anti-GM1 and Anti-GD1b Antibodies During Aripiprazole Treatment.

Background: Transient bulbar palsy without involvement of the facial or extraocular muscles is a rare presentation. It is considered a form of cranial polyneuropathy, a variant of Guillain-Barré syndrome that is related to the autoimmune mechanisms induced by preceding infections or vaccinations. However, drug-induced cranial polyneuropathy has not previously been reported.

Hair Zinc Level Analysis and Correlative Micronutrients in Children Presenting with Malnutrition and Poor Growth.

Purpose: Zinc deficiency can induce serious clinical problems in the gastrointestinal (GI) system and immune system and can affect growth and development. It is more severe in younger patients. Chronic zinc deficiency is reflected more precisely in hair than in serum.

Hierarchically Assembled Nanofibers Created by a Layer-by-Layer Self-Assembly.

We report the hierarchically assembled nanofibers created by LbL self-assembly depending on the PSS-PAA fraction in the blend solutions and pH during bulid-up of the PAH/(PSS-PAA) multilayer films. The multilayer [(PEI/blend)/(PAH/blend)4] films with ρPAA (PSS-PAA fraction in the blend solutions) = 0.0 in the blend solution exhibited surface morphologies of randomly isolated globular clusters, while at ρPAA = 0.

Highly Aligned Poly(vinylidene fluoride-co-hexafluoro propylene) Nanofibers via Electrospinning Technique.

We report on the simple way of obtaining aligned poly(vinylidiene fluoride-co-hexafluoropropylene) (PVDF-HFP) nanofibers by electrospinning process. The collector drum rotation speed was adjusted to prepare well aligned PVDF-HFP nanofibers. The degree of alignment and the orientation of PVDF-HFP nanofibers can be significantly altered by varying the speed of collector drum rotation.

Auto-stereoscopic 3D displays with reduced crosstalk.

In this paper, we propose new auto-stereoscopic 3D displays that substantially reduce crosstalk. In general, it is difficult to eliminate crosstalk in auto-stereoscopic 3D displays. Ideally, the parallax barrier can eliminate crosstalk for a single viewer at the ideal position.
