Physical, genetic, and biochemical analyses of mannityl opine catabolism genes from the Agrobacterium Ti plasmid pTi15955
… cyclase-associated catabolism of mannopine (MOP) and agropine (AGR). Characterization of the transposon-induced lacZ fusion mutants by $\beta$-galactosidase activity and mannityl opine utilization patterns identified at least six genetic units associated with catabolism of these opines. …

Targeting Opioid Receptor Signal Transduction to Produce Sustained Analgesia
Mu opioid receptors (MOPs) in the pain pathway contribute to morphine analgesia. Morphine also stimulates reward/reinforcement through disinhibition of dopaminergic (DA) neurones in the ventral tegmental area (VTA), an effect implicated in its abuse and dependence. We hope to develop approaches to …

Molecular, genetic, and biochemical studies of mannityl opine utilization by Agrobacterium tumefaciens: Its evolutionary implications
… this strain grows slowly with mannopine (MOP) as sole carbon source, but gives rise to spontaneous mutants which grow as fast on this opine as does wild type cells. DNA sequence analysis of the region necessary for utilization of these opines revealed seven putative genes; moc (manniyl …

Assemblies of Metal-Organic Polyhedra: Synthesis, Properties and Characterization
Metal-Organic Polyhedra (MOP) are nanoscale capsule-like supramolecular architectures composed of metal ions and organic linkers. They have well defined cavities depending on the ligand shape and metal-vertex geometry. The thesis concerns MOP composed of 12 copper(II) dimers (Cu24) and 24 …

Characterizing methanogen and methanotroph diversity, abundance and activity within the Hampshire-Avon catchment
… In general, methane oxidation potentials (MOP) and methane production potentials (MPP) were greater in river sediments compared to soils (particularly higher in clays). Sequence analysis identified Methanococcoides, Methanosarcina and Methanocorpusculum as candidates driving methanogenesis …

Polyhalite alters the uptake and partitioning of mineral nutrients in corn
… with POLY4 compared to muriate of potash (MOP;0-0-60). Field studies were conducted in 2017 and 2018 comparing pre-plant applications of 75 lb acre-1 of K2O as MOP, 75 lb acre-1 of K2O as POLY4, and 75 lb acre-1 of K2O as a 75:25 blend of POLY4:MOP to an untreated control. Plants were …

Fragmented maternal care programs altered pain vulnerability and aberrant responses to opioids
… of opioids. <br/><br/>Mu opioid receptors (MOP), delta opioid receptors (DOP), β-arrestin 2 (Barr2) and c-Src kinase are all components of the opioid signalling system, which to differing degrees have been implicated in pain sensitivity and the behavioural effects of opioids including …

Molecular mechanics calculations of tin-bis (triphenylphosphine oxide) complexes
… potential erlerg-y function was invoked for the MOP bond angle. These functions were found to accomodate the wide distribution of observed values better than the traditional harmonic approximations~ Crystal packing influences on the MOP angle were explored thr"ollgh ttle inclusion of the isolated …

Surface-Enhanced Vibrational Spectroscopies using Electrodeposited Anisotropic Gold Nanoparticles
… of gold (III) salt and 4-methoxypyridine (MOP) on a thin film indium tin oxide (ITO) working electrode. The gold nano-daggers (AuND) were demonstrated to be suitable for dual-modality surface-sensitive vibrational spectroscopy, more specifically: surface-enhanced Raman (SERS) and …

Novel Carbon-supported Transition Metal Phosphide Catalysts for Hydrodeoxygenation of Fast Pyrolysis Oil
… and the most active catalyst was selected, i.e., MoP/AC. Two other transition metal phosphides Nickel and Cobalt were also prepared in the same manner using AC support, and their catalytic activities for HDO of pyrolysis oil were compared. The activities of the three catalysts were found to be in …
