Branched Glycopolymers
Linear and branched glycopolymers of a sugar-carrying acrylate monomer, 3-O-acryloyl-1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose (AIGlc), were synthesized via atom transfer radical polymerization (ATRP). Self-condensing vinyl copolymerization (SCVCP) via ATRP was employed for the synthesis of …

Enhanced protein degradation by branched ubiquitin chains
… of eight homogenous and multiple mixed or branched conjugates. While functions of homogenous chain types have been described, physiological roles of branched structures are unknown. The anaphase-promoting complex (APC/C) catalyzes degradation of key regulators during the cell cycle causing …

Combinatorics and Modelling of Highly Branched Polymers
Highly branched polymers such as dendrimers and hyperbranched polymers have a found a variety of chemical applications owing to their unique structural and functional properties, but in many cases are still lacking sufficient theoretical characterization. This thesis takes marginal steps toward …

Single molecule studies of branched polymer dynamics
… of materials such as elasticity and wettability. Branched polymers exhibit strikingly different rheological behavior (e.g. enhanced stress dissipation and strain hardening) compared to linear polymers. In recent years, the dynamic properties of branched polymers have been studied using bulk …

Peptide nanovesicles: supramolecular assembly of branched amphiphilic peptides
… and synthesized a set of 15 and 23-residue branched, amphiphilic peptides that mimic phosphoglycerides in molecular architecture. They undergo supramolecular self-assembly and form solvent-filled, bilayer delineated spheres with 50-150 nm diameters (confirmed by TEM and DLS). Whereas weak …

Synthesis and Characterization of Multiphase, Highly Branched Polymers
… frequently cited as a key application for hyperbranched polymers. However, the high degree of branching in these polymers restricts entanglement and the resultant mechanical properties suffer. Longer distances between branch points may allow entanglements. Highly branched polymers, where linear …

Decibel : transactional branched versioning for relational data systems
As scientific endeavors and data analysis become increasingly collaborative, there is a need for data management systems that natively support the versioning or branching of datasets to enable concurrent analysis, cleaning, integration, manipulation, or curation of data across teams of individuals. …

Flow Behavior of Sparsely Branched Metallocene-Catalyzed Polyethylenes
… resins are deemed controls and include a highly branched low-density polyethylene and a linear low-density polyethylene. Together, the effects of long-chain branching are considered with respect to the shear and extensional rheological properties, the melt fracture behavior, and the ability to …

Targeting RNA Structures with Multivalent Branched Peptide Libraries
… be able to selectively target. To that end, two branched peptide libraries ranging in size from 4,096–46,656 unique sequences were screened for their ability to bind HIV-1 related RNA structures, the transactivation response element (TAR) and the Rev response element (RRE). In addition to …

Synthesis and characterisation of branched poly(ethylene terephthalate)s
… out on the synthesis and characterisation of branched polyesters. The experimental effort concentrated on the branching of PET-type polymers with a variety of potential branching agents, such as trimesic acid, and the control of branching with end-capping agents, such as benzyl alcohol. The …

Deoxyribozymes That Prepare Branched and Linear RNA by Ligation
… 5'-triphosphate RNA have provided mostly 2',5'-branched RNA. Here we report two new in vitro selection strategies designed to favor formation of the native linkage. The first strategy controls the regioselectivity by placing the incipient linkage within a DNA:RNA duplex region, such that 3'-5' …

Advancements in branched bottlebrush polymers for responsive, targeted imaging
… reduction in vivo. Thus, we have developed branched bottlebrush copolymers that display compensatory fluorescence response to nitroxide reduction that enables correlation of MRI contrast, fluorescence intensity, and spin concentration in tissues. These polymers were synthesized by …

Branched-Chain Amino Acid Metabolism in the Neonatal Pig
Branched-chain amino acids (BCAA) are a group of essential amino acids consisting of leucine, isoleucine, and valine. Leucine, in particular, has signaling functions affecting protein and energy metabolism. Plasma leucine concentration is positively correlated with obesity and associated metabolic …

Targeting HIV-1 RNAs with Medium Sized Branched Peptides Featuring Boron and Acridine-Branched Peptide Library Design, Synthesis, High-Throughput Screening and Validation
… we designed and synthesized three generations of branched peptide libraries that resulted in medium sized molecules. The first generation of BPs were discovered from screening a one-bead one-compound library (4,096 compounds) against HIV-1 TAR RNA. One peptide FL4 displayed a binding affinity of …

Constitutive modelling of branched polymer melts in non-linear response
… thesis is concerned with modelling long chain branched polymer melts using the McLeish and Larson Pompom constitutive equations. Usually the non-linear terms in this model are fitted to uniaxial extensional data due its sensitivity to levels of branching, but in this thesis I will study a …

SOURCES AND STRUCTURES OF COMMONLY OCCURRING HIGHLY BRANCHED ISOPRENOID ALKENES
Highly branched isoprenoid (HBI) alkenes are ubiquitous lipids which have been identified in numerous geochemical samples, ranging from recent sediments to ancient oils. At the outset of the current investigation, the diatomaceous algae Haslea ostrearia (C25 alkenes) and Rhizosolenia setigera (C25 …
