Mouse modifiers of intestinal tumorigenesis
Colorectal cancer involves a series of molecular alterations as a normal cell progresses to malignancy. A large body of evidence points to the mutation of the APC gene as the pivotal event initiating intestinal tumorigenesis. Apdmin, an induced mutation in mouse homologue of APC, was identified …

Ordering prenominal modifiers with a ranking approach
… language processing task of ordering prenominal modifiers, a problem that has applications from machine translation to natural language generation. In machine translation, constraints on modifier orderings vary from language to language so some reordering of modifiers may be necessary. In natural …

Socioenvironmental and demographic modifiers of aging in nonhuman animals
… this work uncovers novel intrinsic and extrinsic modifiers of aging at cognitive and immune levels that are highly pertinent to an organism’s health.

Adolescents with Learning and Behavioral Handicaps as Behavior Modifiers
… to perform a more extensive role as behavior modifiers than has previously been demonstrated for mentally handicapped individuals; and (c) generalization of the behavior modification skills was examined across tasks and individuals. Assessment was made of the effectiveness of the adolescents' …

Toughening of cyanate ester networks with reactive thermoplastic modifiers
… system based on Bisphenol-A with thermoplastic modifiers, which were systematically varied with respect to back-bone molecular weight and chemistry. Hydroxyl or cyanato functional Bisphenol-A based amorphous poly(arylene ether)s have been successfully utilized to toughen the cyanate ester …

Applications of modifiers in supercritical fluid extraction and chromatography
The use of modifiers in supercritical fluid chromatography and extraction has become quite common due to the inability of pure carbon dioxide alone to solvate many of the compounds of interest. The effects of modifiers in supercritical fluid chromatography have been more thoroughly studied than the …

SYNTHESIS, TESTING AND CRYSTALLOGRAPHIC STUDIES OF ALLOSTERIC MODIFIERS OF HEMOGLOBIN
The major physiological function of hemoglobin (Hb) is to bind, transport and deliver oxygen to tissues; made efficient by endogenous effectors, such as protons and 2,3-diphosphoglycerate. Synthetic allosteric effectors of Hb (AEHs) are also known to modulate Hb oxygen affinity, showing potential …

Inhibition of Calcium Oxalate Monohydrate Crystallization Using Organic Growth Modifiers
… studies revealed the specific binding of modifiers to COM crystal surfaces. Kinetic studies were performed to quantify both the efficacy and potency of growth inhibitors. These studies demonstrated that increased number of hydroxyl and carboxyl groups play a crucial role in interacting …

Functional properties of polyurethane based sealants blended with polymeric modifiers
Novel polyurethane based two-component self-leveling sealant formulations, incorporating various types of kraft processed lignins including softwood, hardwood, and eucalyptus wood lignin, were produced and their performance properties established in a research program which sought to develop more …

Synthesis and evaluation of novel polymer modifiers for biodegradable polymers
The effects of ester plasticizers and copolymers on the mechanical properties of the natural biodegradable polymers, poly(3-hydroxybutyrate) [PHB] and poly(lactic acid) [PLA] have been studied after subjecting to melt processing conditions. Ester plasticizers were synthesized from citric, tartaric …

Discovery of covalent modifiers via the complexity to diversity strategy
Targeted covalent drugs have recently become integral parts of drug discovery. Given the advantages of high-throughput screening in drug discovery, many electrophilic fragment collections have been developed as a promising alternative to discover and validate novel targets. However, most covalent …

Identifying natural modifiers of meiotic crossover frequency in Arabidopsis thaliana
… This crossover variation can be caused by trans-modifiers within populations, which encode diffusible molecules that influence crossover formation elsewhere in the genome. This project utilised natural accessions of Arabidopsis thaliana to identify trans-modifying loci underlying crossover …

Adsorption of organic friction modifiers at static and sheared interfaces
Organic friction modifiers (OFMs) are additives that can be added to engine oils to reduce friction between rubbing surfaces. OFMs are thought to reduce friction by adsorbing at engine surfaces, producing films that are conventionally thought to be one molecule thick. Although established, the …

Structure-property relationships of functionalized modifiers for thermosetting resin systems
… polysiloxane elastomer and thermoplastic modifiers and their morphological implications to the toughening and physical behavior of, principally, epoxy thermosetting systems. Secondary amine-terminated poly(dimethyl-co-diphenyl siloxane) oligomers were found to be comparable tougheners to …

Single wall carbon nanotubes as viscosity modifiers in polypropylene matrix nanocomposites
… (SWNTs) were studied as low shear rate viscosity modifiers in the polypropylene matrix of nanocomposites. To create nanocomposites which did not demonstrate increased low shear rate viscosity when nanotubes were added into the polymer melt, this work focused on modifying the sidewall profile of …
