Biorubber (PGS) : evaluation of a novel biodegradable elastomer
Poly(glycerol sebacate) (PGS), or biorubber, is a tough, biodegradable elastomer made from biocompatible monomers. The material was designed, synthesized and characterized in the Department of Chemical Engineering at MIT. Its main features are good mechanical properties, rubberlike elasticity and …

Characterizing the Thermal Behavior of Pyrolytic Graphite Sheets (PGS) at Low Interface Pressures
… usability metrics. Pyrolytic Graphite Sheets (PGS) were chosen to be investigated further. Second, a fourth order thermal conductivity model for PGS as a function of interface pressure was derived in the 0 – 10 PSI range. This model is important as it allows engineers to have conductivity …

Canadian counselling psychology graduate student knowledge of women problem gamblers
… individuals to become problem gamblers (PGs) at higher rates than others. For instance, women problem gamblers (WPGs) present with different gambling motivations than their male counterparts. Traditionally, gambling research has focused on males, leading to a dearth of WPG information and …

How do teachers' beliefs affect the implementation of inquiry-based learning in the PGS Curriculum? A case study of two primary schools in Hong Kong.
… part of this, the new Primary General Studies (PGS) programme implemented in 2004, adopted an inquiry-based learning approach. The literature shows that inquiry-based learning not only has origins linked to science inquiry and Dewey’s theory of inquiry, but also intersects with theories of …

The role of glycoproteins in glomerular pathophysiology
… demonstrates the importance of proteoglycans (PGs) in the endothelial cell surface layer for an intact glomerular filtration barrier. Loss of PGs from this layer led to increased proteinuria in rats, and analysis of human glomerular tissue and cells cultured in diabetic-like conditions revealed …

Biodegradable microfluidic scaffolds for vascular tissue engineering
… this scaffolds from poly(glycerol-sebacate) (PGS), a novel biodegradable elastomer with superior mechanical properties. The transport properties of oxygen and carbon dioxide in PGS were measured through a series of time-lag diffusion experiments. The results of these measurements were used to …

Proteinpolysaccharides from Bovine Nasal Cartilage Interactions with Glycoproteins and the Formation of Aggregates
… a fraction referred to as proteoglycan subunit, PGS. PGS contained 7% protein, 8% keratan sulfate and 85% chondroitin sulfate. In associative solvent conditions, PGS contained no aggregate. PGS reaggregated when it was mixed with GPL. The amount of aggregate regenerated in a mixture was greater …

Plurigaussian Simulation of rocktypes using data from a gold mine in Western Australia
… and more complex plurigaussian simulation (PGS). Comparisons between the three models are made by examining global and regional rocktype (lithotype) proportions of the outputs of the models, both visually and empirically. The models are validated by considering the contacts which occur in …

Endocytosis of therapeutic macromolecules in tumor cells - Mechanistic aspects of the proteoglycan receptor function
… cell surface heparan sulfate proteoglycans (HS PGs) for efficient uptake, however the details of this mechanism and the exact role of the PG has been unclear. The aim of this thesis was to clarify the role of the cell surface PG in macromolecular uptake processes. It is demonstrated that …

Common genetic variation and spliceosome variants in rare developmental disorders
… variants in severe NDDs using polygenic scores (PGS) in both DDD and the Genomics England (GEL) 100,000 Genomes project. I tested whether undiagnosed NDD probands over- or under- inherit PGS for NDDs and correlated traits. I found that NDD probands over-inherit PGS for NDDs and schizophrenia. To …

Implementation of automatic inspection system
… a product called pyrolytic graphite sheet (PGS) is manufactured and at present the types of defects that occur during their manufacturing process can only be identified visually. The problem with using human senses as a tool to perform an inspection is that the accuracy and speed of the …

NOVEL NANOFIBER-BASED GRAFT FOR HEART VALVE REPLACEMENT
… elastic polymer poly(glycerol-sebacate) (PGS). The central hypothesis of this project was: Electrospun grafts created from composites of type I collagen, silk fibroin, and PGS are stable, less thrombogenic and more readily available than the conventionally used collagen-based grafts for …

Studies on the Possible Regulatory Function of Dietary Alpha-Linolenic Acid in Prostaglandin Synthesis by Immunocompetent Cells
… of essential fatty acid (EFA), and therefore of PGs, in cell-mediated immunity has increasingly become of interest. Prostaglandins have been implicated in many areas of the immune response. Three studies were conducted examining both in vivo and in vitro rat immune models to study the regulatory …

Behavioral and Physiological Responses to Lipopolysaccharide in the Chicken
… To investigate the role of prostaglandins (PGs) in the behavioral and physiological responses to LPS, chickens were injected with indomethacin i.p. or i.c.v. and their behavior and T$\sb{\rm b}$ following a challenge i.p. injection of LPS was measured. Our results are interpreted to indicate …
