ABSTRACT

Current conditions of 2-11 kJ m^sup -2^ day^sup -1^ of UV-B radiation and temperatures of >30°C during flowering in cotton cultivated regions are projected to increase in the future. A controlled environment study was conducted in sunlit growth chambers to determine the effects of UV-B radiation and temperature on physiology, growth, development and leaf hyperspectral reflectance of cotton. Plants were grown in the growth chambers at three day/night temperatures (24/16°C,...

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

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

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,

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
