In cowpea (Vigna unguiculata), fall armyworm (Spodoptera frugiperda) herbivory and oral secretions (OS) elicit phytohormone production and volatile emission due to inceptin [Vu-In; ^sup +^ICDINGVCVDA^sup -^], a peptide derived from chloroplastic ATP synthase γ-subunit (cATPC) proteins. Elicitor-induced plant volatiles can function as attractants for natural enemies of insect herbivores. We hypothesized that inceptins are gut proteolysis products and that larval OS should contain a mixtur...

Pharmacokinetics and Biodistribution of ^sup 111^In- and ^sup 177^Lu-Labeled J591 Antibody Specific for Prostate-Specific Membrane Antigen: Prediction of ^sup 90^Y-J591 Radiation Dosimetry Based on ^sup 111^In or ^sup 177^Lu?
The Journal of Nuclear Medicine ; ^sup 111^In-Labeled antibodies and peptides have been routinely used as chemical and biologic surrogates for ^sup 90^Y-labeled therapeutic agents. However, recent studies have shown that there are significant differences in biodistribution between ^sup 111^In- and ^sup 90^Y-labeled agents. Yttrium

The Journal of Nuclear Medicine ; ^sup 99m^Tc-Mercaptoacetyltriglycine (^sup 99m^Tc-MAG3) and ^sup 99m^Tc-L,L-ethylenedicysteine (^sup 99m^Tc-LL-EC) are useful renal radiopharmaceuticals; however, both agents have renal clearances less than that of ^sup 131^I-orthoiodohippurate (^sup 131^I-OIH), and ^sup 99m^Tc-LL-EC exists in
Effects of Intracellular and Extracellular Concentrations of Ca^sup 2+^, K+, and Cl- on the Na+-Dependent Mg^sup 2+^ Efflux in Rat Ventricular Myocytes
Biophysical Journal ; ABSTRACT Intracellular Mg^sup 2+^ concentration ([Mg^sup 2sub i^) was measured in rat ventricular myocytes with the fluorescent indicator furaptra (25C). After the myocytes were loaded with Mg^sup 2 the initial rate of decrease in [Mg^sup 2sub i^ (initial Δ[Mg^sup 2sub i916;t) was estimated
Development of a Novel ^sup 99m^Tc-Chelate-Conjugated Bisphosphonate with High Affinity for Bone as a Bone Scintigraphic Agent
The Journal of Nuclear Medicine ; In bone scintigraphy using ^sup 99m^Tc with methylenediphosphonate (^sup 99m^Tc-MDP) and hydroxymethylenediphosphonate (^sup 99m^Tc-HMDP), it takes 2-6 h after an injection before imaging can start. This interval could be shortened with a new radiopharmaceutical with higher affinity for bone. Here,
Processing of Generator-Produced ^sup 68^Ga for Medical Application
The Journal of Nuclear Medicine ; The ^sup 68^Ge/^sup 68^Ga generator provides an excellent source of positron-emitting ^sup 68^Ga. However, newly available "ionic" ^sup 68^Ge/^sup 68^Ga radionuclide generators are not necessarily optimized for the synthesis of ^sup 68^Ga-labeled radiopharmaceuticals. The eluates have rather large
