Although genetic factors are involved in the etiology of autism spectrum disorder (ASD), the significance of genetic analysis in clinical settings is unclear. Forty-nine subjects diagnosed with non-syndromic ASD were analyzed by microarray comparative genomic hybridization (CGH) analysis, whole-exome sequencing (WES) analysis, and panel sequencing…

To retrospectively explore the characteristics of plasma amino acids (PAAs) in children with autism spectrum disorder and their clinical association via case-control study. A total of 110 autistic and 55 healthy children were recruited from 2014 to 2018. The clinical phenotypes included severity of autism, cognition, adaptability, and regression.…

Unlike in other countries, heredity and genetics appear first in Spanish science standards in secondary levels. However, some researchers have suggested the need of progressively introducing some basic genetic ideas already from primary education levels. In this context of no formal instruction in early stages, the objectives of our work were to…

The objectives of this study were to identify gaps in educational training for undergraduate and graduate students in agricultural data science, propose paths for filling these gaps, and provide an annotated list of resources currently available to different training levels. Data in this study was collected through three voluntary surveys catered…

Purpose: The heterogeneity of autism is well documented, but few studies have studied the heterogeneity of gesture production ability in autistic children. The present study aimed to identify subgroups of autistic children who displayed heterogeneous gesture production abilities and explore the underlying factors, including autism characteristics,…

Prior theoretical and empirical research has highlighted links between positive parenting and the socioeconomic characteristics of the family's neighborhood, but has yet to illuminate the etiologic origins of this association. One possibility is that the various predictors of parenting outlined by Belsky (1984; e.g., characteristics of the child,…

Parenting behaviors have long been recognized as crucial to children's healthy development. However, examinations of the etiology of these behaviors are less prevalent. The current study investigated the driving forces behind parental warmth and discipline, particularly whether they are related more to traits within the parent or reactions to…

This dissertation consists of two distinct bodies of work. The first leverages a unique aspect of fire ant biology to investigate a potential role for a supergene in genetic assimilation. A supergene refers to a chromosome structural rearrangement, such as an inversion, that regulates the production of an alternative phenotype within a species. In…

Prader-Willi Syndrome (PWS) is a rare neurodevelopmental disorder associated with social cognitive challenges, and pretend play has been demonstrated as a tool to achieve developmental goals. Following previous report on feasibility and acceptability of a remote, play-based parent-training program (Zyga, Russ, & Dimitropoulos, 2018), we now…

One of the overriding hopes of the Down syndrome (DS) research community is to arrive at a better understanding of how trisomy 21 affects brain development and function, and that doing so will improve quality of life and independence for people with DS. In searching for the underlying causes of intellectual disability in DS, researchers and…

Whether there is a relationship between oxytocin (OXT) use in labor and the risk of autism (ASD), and the nature of such relationship, is unclear. By integrating genetic and clinical data in a sample of 176 ASD participants, we tested the hypothesis that OXT is a marker for abnormal prenatal development which leads to impairments in the process of…

The ability to perceive approximate numerosity is present in many animal species, and emerges early in human infants. Later in life, it is moderately heritable and associated with mathematical abilities, but the etiology of the Approximate Number System (ANS) and its degree of independence from other cognitive abilities in infancy is unknown.…

The use of molecular models in chemistry and biochemistry classes is very effective in helping students understand covalent bonds and the chemical structure of molecules. However, conventional molecular models cannot represent intermolecular interactions such as hydrogen bonds and electrostatic interactions. Herein, we describe 3D printed…

Pedigree problems are typical genetics tasks in schools. They are well suited to help students learn scientific reasoning, representing realistic genetic problems. However, pedigree problems also pose complex requirements, especially for secondary students. They require a suitable solution strategy and technical knowledge. In this study, we…

Apurinic/apyrimidinic (AP or abasic) sites are deoxyribonucleic acid (DNA) lesions that result from the loss of a nucleobase by hydrolysis of the "N"-glycosyl bond. AP sites are the most frequent lesions in cells and are caused by environmental and cancer therapeutic genotoxins. Herein, the bicinchoninic colorimetric assay, typically…
