Choline monooxygenase, an unusual iron-sulfur enzyme catalyzing the first step of glycine betaine synthesis in plants: prosthetic group characterization and cDNA cloning.
Plants synthesize the osmoprotectant glycine betaine via the route choline --> betaine aldehyde --> glycine betaine. In spinach, the first step is catalyzed by choline monooxygenase (CMO), aExpand

Osmoprotective compounds in the Plumbaginaceae: a natural experiment in metabolic engineering of stress tolerance.
In common with other zwitterionic quarternary ammonium compounds (QACs), glycine betaine acts as an osmoprotectant in plants, bacteria, and animals, with its accumulation in the cytoplasm reducingExpand

Assay, Purification, and Partial Characterization of Choline Monooxygenase from Spinach
The osmoprotectant glycine betaine is synthesized via the path-way choline -> betaine aldehyde -> glycine betaine. In spinach (Spinacia oleracea), the first step is catalyzed by choline monooxygenaseExpand

AMITROLE, TRIAZINE, SUBSTITUTED UREA, AND METRIBUZIN RESISTANCE IN A BIOTYPE OF RIGID RYEGRASS (LOLIUM-RIGIDUM)
A biotype of rigid ryegrass (Lolium rigidum G. #3 LOLRI) has become resistant to amitrole and atrazine after 10 yr of exposure to a mixture of these herbicides. Resistance has also been demonstratedExpand

cDNA cloning and sequence determination of the pheromone biosynthesis activating neuropeptide of Mamestra brassicae: a new member of the PBAN family.
Sex pheromone biosynthesis in a number of moth species is induced by a conserved 33-amino acid amidated neuropeptide PBAN (pheromone biosynthesis activating neuropeptide). Here, using immunoblottingExpand

Synthetic Farnesoid X Receptor Agonists Induce High-Density Lipoprotein-Mediated Transhepatic Cholesterol Efflux in Mice and Monkeys and Prevent Atherosclerosis in Cholesteryl Ester Transfer Protein
Farnesoid X receptor (FXR), a bile acid-activated nuclear hormone receptor, plays an important role in the regulation of cholesterol and more specifically high-density lipoprotein (HDL) homeostasis.Expand

Longitudinal PET-MRI reveals β-amyloid deposition and rCBF dynamics and connects vascular amyloidosis to quantitative loss of perfusion
The dynamics of β-amyloid deposition and related second-order physiological effects, such as regional cerebral blood flow (rCBF), are key factors for a deeper understanding of Alzheimer's diseaseExpand

AWD-12-281 (inhaled) (elbion/GlaxoSmithKline).
elbion (formerly ASTA Medica) and GlaxoSmithKline are developing an inhaled formulation of AWD-12-281 for the potential treatment of chronic obstructive pulmonary disease (COPD). By May 2005, phaseExpand

Plasma volume expansion with solutions of hemoglobin, albumin, and Ringer lactate in sheep.
We have measured plasma volume expansion (Evans blue and hematocrit changes) and hemodynamic responses in conscious hemorrhaged and normovolemic splenectomized sheep after a 30-min infusion of eitherExpand
