John W McCarthy, Jamie B Boster
Although recent evidence suggests learning demands for children can be reduced by organizing augmentative and alternative communication (AAC) displays in contextual scenes, there is little evidence on how such scenes could be made accessible for children who cannot use direct selection. Using a line drawn scene of a living room, a traditional traveling cursor (a green outline of objects within the scene) was compared with sequential animation-logically matching the function of items in the scene (e.g., hands of a clock moving, a lamp turning on and off, etc...

The grafting of polyacrylic acid (PAAc) onto the fabric of Poly(ethyleneterephthalate) (PET) was loaded with TiO2 by a mixture sonication of TiO2 dispersed in AAc dissolved in acetone solvent. Ultrasonic irradiation was utilized as a tool for a good dispersion of TiO2 onto the PET fabric. The grafted PET fabrics with acrylic acid AAc monomer were successfully obtained using gamma-ray induced graft polymerization, the degree of grafting PET-g-PAAc fiber was 105%. The chemical compositions and crystal structure of grafted TiO2@PET-g-PAAc fabrics were characterized by ATR-FTIR and XRD...

Rice eating and cooking quality is largely determined by starch physicochemical properties. The diverse accessions in the USDA rice mini-core collection (URMC) facilitate extensive association analysis of starch physicochemical properties with molecular markers specific to starch biosynthesis related genes. To identify significant trait-marker associations that can be utilized in rice breeding programs for improved starch quality, we conducted two association analyses between 26 molecular markers derived from starch biosynthesis related genes and 18 parameters measured of starch physicochemical properties in two sets of the mini-core accessions successfully grown in two environments in China...

Explosive growth in the study of microbial epigenetics has revealed a diversity of chemical structures and biological functions of DNA modifications in restriction-modification (R-M) and basic genetic processes. Here, we describe the discovery of shared consensus sequences for two seemingly unrelated DNA modification systems, (6m)A methylation and phosphorothioation (PT), in which sulfur replaces a nonbridging oxygen in the DNA backbone. Mass spectrometric analysis of DNA from Escherichia coli B7A and Salmonella enterica serovar Cerro 87, strains possessing PT-based R-M genes, revealed d(GPS(6m)A) dinucleotides in the GPS(6m)AAC consensus representing ∼5% of the 1,100 to 1,300 PT-modified d(GPSA) motifs per genome, with (6m)A arising from a yet-to-be-identified methyltransferase...

We present an evolutionary hypothesis assuming that signals marking nucleotide synthesis (DNA replication and RNA transcription) evolved from multi- to unidimensional structures, and were carried over from transcription to translation. This evolutionary scenario presumes that signals combining secondary and primary nucleotide structures are evolutionary transitions. Mitochondrial replication initiation fits this scenario. Some observations reported in the literature corroborate that several signals for nucleotide synthesis function in translation, and vice versa...

Hemoglobin (Hb) is the protein responsible for oxygen transportation. It is a tetrameric protein comprising two α- and two β-globin subunits. In the literature, a large number of mutations in the α- and β-globin genes have been documented. Among these mutations, Hb Presbyterian (HBB: c.327 C>G), is a naturally occurring mutant exerting low oxygen affinity. The C to G exchange (AAC>AAG) at codon 108 of the β-globin gene results in the substitution of asparagine by lysine. Here, we document the identification of HBB: c...

Participation has a subjective and private dimension, and so it is important to hear directly from youth about their experiences in various activity settings, the places where they "do things" and interact with others. To meet this need, our team developed the Self-Reported Experiences of Activity Settings (SEAS) measure, which demonstrated good-to-excellent measurement properties. To address the needs of youth who could benefit from graphic symbol support, the SEAS-PCS(TM), (1) was created. The purpose of this paper is to describe the development of SEAS-PCS and the preliminary study that explores the equivalency of the SEAS and SEAS-PCS...

Parents play an important role in the successful implementation of AAC. Previous research has indicated that parents in different countries have varying perceptions about the use of AAC and face different challenges in its implementation. To date, there is limited information about the use of AAC by children in Malaysia or parents' views about its use. The aim of this study was to explore Malaysian parents' perception of AAC and their experience when supporting their children who use AAC. For this study, 12 parents of children with autism spectrum disorder and cerebral palsy were involved in semi-structured individual interviews...

Hydroxyethylcellulose (HEC)/acrylic acid (AAc) copolymer gels with superabsorbent properties were synthesized from aqueous solutions by radiation-initiated crosslinking. The effect of the acrylic acid content on gel properties was determined at different synthesis conditions. The partial replacement of the cellulose derivative with acrylic acid improved the gelation, leading to higher gel fraction and lower water uptake even in very low concentrations (1-5%). In the presence of acrylic acid lower dose and solute concentration was required for the gel synthesis...

BACKGROUND: Coronary artery calcification (CAC) is highly prevalent among dialysis patients and is associated with increased cardiovascular and all cause mortality. Magnesium (Mg) inhibits vascular calcification in animal and in-vitro studies but whether the same effect occurs in humans is uncertain. METHODS: A single centre cross-sectional study of 80 prevalent peritoneal dialysis (PD) patients; on PD only for a minimum of 3 months. A radiologist blinded to patient status calculated their abdominal aortic calcification (AAC) scores on lateral lumbar spine radiographs, a validated surrogate for CAC...

In older adults, lower bone density in the proximal femur was associated with increased heart burden, and this association was linked to calcification in the aorta. These results were seen in women but not in men. PURPOSE: To determine whether there is an association between lower bone mineral density (BMD) and increased cardiac workload in older adults, and if this association was independent of abdominal aortic calcification (AAC). METHODS: Three hundred thirty-seven participants [mean ± SD age = 70 ± 5 years and BMI = 28 ± 5 kg/m(2), 61% females] had BMD determined by dual-energy X-ray absorptiometry and AAC determined by radiography...
