Specific and Reversible DNA-Directed Self-Assembly of Modular Vesicle-Droplet Hybrid Materials.

Modular hybrid structures functionalized to assemble in a controlled manner possess diverse properties necessary for a new generation of complex materials and applications. Here, we functionalized giant unilamellar vesicles and emulsion droplets with biotinylated single-stranded DNA oligonucleotides using streptavidin as an intermediary linker to demonstrate specific and reversible DNA-directed self-assembly into vesicle-droplet hybrid structures. A low molar percentage of PEGylated phospholipids independent of the DNA-based recognition machinery at the supramolecular surface modulated the stability of the system.

Preliminary Evidence for the Integrated Systems Using Telemedicine.

Background: Autism affects as many as 1 in 68 children in the United States. Early identification and access to intervention services promote improved outcomes for children with autism and other developmental delays. Children living in rural and underserved areas have limited access to such services and are diagnosed later than those living more suburban and urban areas.

Brief report: use of interactive television in identifying autism in young children: methodology and preliminary data.

Children living in rural and underserved areas experience decreased access to health care services and are often diagnosed with autism at a later age compared to those living in urban or suburban areas. This study examines the utility and validity of an ASD assessment protocol conducted via video conferencing (VC). Participants (n = 17) included families with young children (2.

Detection of antibodies to the feline leukemia Virus (FeLV) transmembrane protein p15E: an alternative approach for serological FeLV detection based on antibodies to p15E.

The aim of this report was to investigate whether the diagnosis of feline leukemia virus (FeLV) infection by serology might be feasible and useful. Among the various viral proteins, the FeLV env-gene product (SU) and the envelope transmembrane protein p15E were considered promising candidates for the serological diagnosis of FeLV infection. Thus, we evaluated p15E and three other FeLV antigens, namely, a recombinant env-gene product, whole FeLV, and a short peptide from the FeLV transmembrane protein, for their potential to detect FeLV infection.

The MATCHIT automaton: exploiting compartmentalization for the synthesis of branched polymers.

We propose an automaton, a theoretical framework that demonstrates how to improve the yield of the synthesis of branched chemical polymer reactions. This is achieved by separating substeps of the path of synthesis into compartments. We use chemical containers (chemtainers) to carry the substances through a sequence of fixed successive compartments.
