Sabrina Saunders-Hodge
No full textSabrina Saunders-Hodge is the manager of the New Entrants Division within the Federal Aviation Administration’s NextGen Portfolio Management and Technology Development directorate and is responsible for leading the execution of strategies required to effectively integrate portfolios of viable research (internal & external to the FAA) resulting in solutions that address key operational challenges as well as improvements for integrating New Entrants into the National Airspace System (NAS).
Within this role, Ms. Saunders-Hodge has program management responsibility for the FAA’s UAS Center of Excellence as well as the execution of R&D to support both Aviation Safety and NextGen requirements for UAS integration into the NAS, wake separation standards, closely spaced parallel operations, and ground based augmentation system cost benefit studies. Additionally, Ms. Saunders-Hodge’s Division has a leading role in collaborating with external domestic and international partners, such as the U.S. Department of Defense, NASA, and the European Organisation for the Safety of Air Navigation (EUROCONTROL), to leverage relevant R&D to support the FAA’s goals.
Over the past twenty five years Ms. Saunders-Hodge has worked in the field of satellite communications, contributed to the development of ICAO’s global plan for transitioning to future communications, navigation, surveillance and air traffic management (CNS/ATM) systems for civil aviation, co-managed the oversight of FAA/European cooperative research and development initiatives, and worked on the development of operational concepts for technology enhancements within the NAS.
Ms. Saunders-Hodge holds a B.S. and M.S. in Computer Science from The University of Maryland and Johns Hopkins University respectively. Additionally, Ms. Saunders-Hodge is a certified Project Management Professional and a graduate of the Federal Executive Institute.https://commons.erau.edu/faa-uas-bios/1008/thumbnail.jp

Ontogeny and Phylogeny of Brain Barrier Mechanisms.
Get PDFThe brain functions within an internal environment that is determined and controlled by morphological structures and cellular mechanisms present at interfaces between the brain and the rest of the body. In vertebrates these interfaces are across cerebral blood vessels (blood-brain barrier) choroid plexuses (blood-cerebrospinal fluid barrier) and pia-arachnoid. There is a CSF-brain barrier in the neuroepithelium lining the ventricular system that is only present in embryos. There is now substantial evidence that many brain barrier mechanisms develop early and that in some cases they are functionally more active and even more specialized compared to adult barriers. Therefore barriers in developing brain should be viewed as adapted appropriately for the growing brain and not, as is still widely believed, immature. Considerable advances in our understanding of these barrier mechanisms have come from studies of the developing brain and invertebrates. A striking aspect, to be highlighted in this special edition, is that many of the molecular mechanisms in these very diverse species are similar despite differences in the cellular composition of the interfaces. This Frontiers Topic comprises articles in three sections: Original studies, Reviews and Myths & Misconceptions. Original articles provide new information on molecular and cellular barrier mechanisms in developing brains of primates, including human embryos (Brøchner et al., Ek et al., Errede et al.), rodents (Bauer et al., Liddelow, Strazielle & Ghersi-Egea, Saunders et al., Whish et al.), chick (Bueno et al.) and zebrafish (Henson et al.) as well as studies in drosophila (Hindle & Bainton, De Salvo et al., Limmer et al.). The Reviews section includes evolutionary perspectives of the blood-brain and blood-CSF barriers (Bueno et al., Bill & Korzh). There are also detailed reviews of the current state of understanding of different interfaces and their functional mechanisms in developing brain (Bauer et al., Strazielle & Gjersi-Egea, Liddelow, Richardson et al., Errede et al., Henson et al., Brøchner et al.) and in invertebrates (Hindle & Bainton, De Salvo et al., Limmer et al). Different aspects of the relationship between properties of the internal environment of the brain and its development are discussed. (Stolp & Molnar, Johansson, Prasongchean et al.). A neglected area, namely barriers over the surface of the brain during development is also covered (Brøchner et al.). Clinically related perspectives on barrier disruption in neonatal stroke are provided by Kratzer et al. and other aspects of dysfunction by Morretti et al. and by Palmeta et al. on the continuing problem of bilirubin toxicity. Progress in this field is hampered by many prevailing myths about barrier function, combined with methodologies that are not always appropriately selected or interpreted. These are covered in the Misconceptions, Myths and Methods section, including historical aspects and discussion of the paracellular pathway, a central dogma of epithelial and endothelial biology (Saunders et al.) and a review of markers used to define brain barrier integrity in development and in pathological conditions (Saunders et al.). Use of inappropriate markers has caused considerable confusion and unreliable interpretation in many published studies. Torbett et al. deal with the complexities of the new field of applying proteomics to understanding blood-brain barrier properties as do Huntley at al. with respect to applying modern high throughput gene expression methods (Huntley et al.). The Editorial summarizes the contributions from all authors. This includes mention of some the main unanswered but answerable questions in the field and what the impediments to progress may be
A study of thermoassociative gelation of aqueous cationic poly(N-isopropyl acrylamide) graft copolymer solutions
No full textIn this work thermoassociative gel formation of a new family of aqueous temperature-responsive copolymer solutions has been investigated. This was achieved using a cationic poly(N-isopropyl acrylamide) (PNIPAm) graft copolymer recently prepared [Liu R, De Leonardis P, Cellesi F, Tirelli N, Saunders BR. Langmuir 2008;24:7099]. The PDMA+x-g-(PNIPAmn)y copolymers have x and y values that originate from the macroinitiator; the value for n corresponds to the PNIPAm arm length. DMA+ is quarternarized N,N-dimethylaminoethyl methacrylate. The copolymer solutions exhibited cloud point temperatures (Tclpt) of about 33 °C, which were not significantly affected by x/y ratio or the value for n. Thermoassociative gel formation occurred above Tclpt at copolymer concentrations (Ccopol) greater than or equal to 4 wt.%. This is a reasonably low Ccopol value and is a consequence of the graft copolymer architecture employed. We investigated the effect of temperature, Ccopol and copolymer structure on gelation and gel elasticity using variable - temperature dynamic rheology. For PDMA+30-g-(PNIPAm210)14 solutions at 39 °C it was found that G′ (elastic modulus) scales with Ccopol according to G′ ∼ Ccopol3.85. The data suggested that a significant proportion of PNIPAm units is not directly involved in network formation. Thermoassociative gel formation and the gel properties for these systems appear to be governed by a balance between electrostatic repulsion involving the DMA+ units (favouring spatial extension of the copolymer backbones) and attractive hydrophobic interactions between PNIPAm side chains (favouring associative crosslink formation). © 2009 Elsevier Ltd.
