Clinical spectrum of KIAA2022 pathogenic variants in males: Case report of two boys with KIAA2022 pathogenic variants and review of the literature.

KIAA2022 is an X-linked intellectual disability (XLID) syndrome affecting males more severely than females. Few males with KIAA2022 variants and XLID have been reported. We present a clinical report of two unrelated males, with two nonsense KIAA2022 pathogenic variants, with profound intellectual disabilities, limited language development, strikingly similar autistic behavior, delay in motor milestones, and postnatal growth restriction.

Abdominal wall and labial edema presenting in a girl with Henoch-Schönlein purpura: a case report.

Introduction: Henoch-Schönlein purpura is a common immunoglobulin A-mediated vasculitic syndrome in children, characterized by purpuric rash, arthritis and abdominal pain. Renal involvement, manifested by the presence of hematuria and/or proteinuria, is also frequently seen. In most cases, patients with this disease achieve complete recovery, but some progress to renal impairment.

Impact of genetics and environment on nutritional and metabolite components of maize grain.

The Organization for Economic Co-operation and Development (OECD) recommends the measurement of specific plant components for compositional assessments of new biotechnology-derived crops. These components include proximates, nutrients, antinutrients, and certain crop-specific secondary metabolites. A considerable literature on the natural variability of these components in conventional and biotechnology-derived crops now exists.

Metabolite analyses of grain from maize hybrids grown in the United States under drought and watered conditions during the 2002 field season.

Understanding natural variation in the composition of conventional crop germplasms is critical in establishing a baseline for comparison of biotechnology-derived crops. This is particularly relevant to such traits as tolerance to drought stress. Thus, there is both a need to understand the contribution of stress conditions to natural variation in plant nutritional components and to determine whether levels of small molecule metabolites such as osmoprotectants and stress metabolites are also affected.

The use of complementary and alternative medicine in children with chronic medical conditions.

Objectives: The objectives of this study were to examine whether progressive medical conditions lead to greater use of complementary and alternative medicine (CAM) as compared with more stable conditions, to see whether disease severity influences CAM use, and to identify the main motivations behind CAM use.

Methods: Subjects were selected from outpatient clinics at Hotel Dieu Hospital. Surveys were conducted by mail and telephone.

Patterns of complementary and alternative medical therapy use in children diagnosed with autism spectrum disorders.

Previous studies suggest that complementary and alternative medical (CAM) therapy use in children with chronic illnesses is higher than in children in the general population. In this study, we investigated patterns of CAM therapy use in children diagnosed with autism spectrum disorders (ASD, n = 50) as compared to a control population of children with no ASD (n = 50). Over half of the parents in the ASD group reported using, or had used at least one CAM therapy for their child (52%) as compared to 28% of the control group (P = 0.

Solid Phase Synthesis of beta-Peptoids: N-Substituted beta-Aminopropionic Acid Oligomers.

A solid-phase organic synthesis method has been developed for the preparation of N-substituted-beta-aminopropionic acid oligomers or beta-peptoids 1. Treatment of polymer-bound 4-(benzyloxy)benzyl acrylate 2 with primary amines afforded N-substituted beta-alanines 3. Polymer loadings and product conversions were determined by direct cleavage of resin-bound materials and measurement by (1)H NMR with an internal standard.
