Vineland-3 Structural Validity and Interpretability of Domain Scores: Implications for Practitioners Assessing Adolescents With Developmental Conditions.

The Vineland-3 purports to measure three dimensions of adaptive behavior, but empirical evidence pertaining to its structural validity is lacking. In this study, factor analyses were conducted on the standardization sample data for the comprehensive forms within the 11- to 20-year-old age range. Results did not support the three domain structure of the test and indicated domain scores did not add additional information about an individual's adaptive performance that was not already accounted for by the Adaptive Behavior Composite (ABC) score alone.

Plant Thaumatin-like Proteins: Function, Evolution and Biotechnological Applications.

Thaumatin-like proteins (TLPs) are a highly complex protein family associated with host defense and developmental processes in plants, animals, and fungi. They are highly diverse in angiosperms, for which they are classified as the PR-5 (Pathogenesis-Related-5) protein family. In plants, TLPs have a variety of properties associated with their structural diversity.

Plant Aquaporins: Diversity, Evolution and Biotechnological Applications.

The plasma membrane forms a permeable barrier that separates the cytoplasm from the external environment, defining the physical and chemical limits in each cell in all organisms. The movement of molecules and ions into and out of cells is controlled by the plasma membrane as a critical process for cell stability and survival, maintaining essential differences between the composition of the extracellular fluid and the cytosol. In this process aquaporins (AQPs) figure as important actors, comprising highly conserved membrane proteins that carry water, glycerol and other hydrophilic molecules through biomembranes, including the cell wall and membranes of cytoplasmic organelles.

Cowpea and abiotic stresses: identification of reference genes for transcriptional profiling by qPCR.

Background: Due to cowpea ability to fix nitrogen in poor soils and relative tolerance to drought and salt stresses, efforts have been directed to identifying genes and pathways that confer stress tolerance in this species. Real-time quantitative PCR (qPCR) has been widely used as the most reliable method to measure gene expression, due to its high accuracy and specificity. In the present study, nine candidate reference genes were rigorously tested for their application in normalization of qPCR data onto roots of four distinct cowpea accessions under two abiotic stresses: root dehydration and salt (NaCl, 100 mM).

However, there are no data on the toxicity of their mixtures.

Utility of the CBCL DSM-Oriented Scales in Assessing Emotional Disorders in Youth with Autism.

Background: Youth with autism spectrum disorder (ASD) are at risk for one or more emotional disorders (ED) including depressive and anxiety conditions. DSM-5 diagnostic guidelines indicate that co-occurring ED must be specified when present (APA, 2013). While ED may be evaluated for during initial diagnostic assessment, routine monitoring and screening is needed to identify emerging ED in later childhood and adolescence, a period of high risk.

Alginate-Based Cell Microencapsulation for Tissue Engineering and Regenerative Medicine.

Increasing numbers of requests for transplantable organs and their scarcity has led to a pressing need to find alternative solutions to standard transplantation. An appealing but challenging proposal came from the fields of tissue engineering and regenerative medicine, the purpose of which is to build tissues/organs from scratch in the laboratory and use them as either permanent substitutes for direct implantation into the patient's body, or as temporary substitutes to bridge patients until organ regeneration or transplantation. Using bioartificial constructs requires administration of immunosuppressant therapies to prevent rejection by the recipient.

Epigenetic Signals on Plant Adaptation: a Biotic Stress Perspective.

For sessile organisms such as plants, regulatory mechanisms of gene expression are vital, since they remain exposed to climatic and biological threats. Thus, they have to face hazards with instantaneous reorganization of their internal environment. For this purpose, besides the use of transcription factors, the participation of chromatin as an active factor in the regulation of transcription is crucial.
