Background: Serum creatinine is the most commonly used marker for estimation of glomerular filtration rate (GFR). To compensate for its drawbacks as a GFR marker, several prediction equations including several parameters are being used, with the Modification of Diet in Renal Disease (MDRD), Schwartz, and CounahanBarratt equations being the ones most widely accepted for estimation of relative GFR in mL . min^sup -1^ . (1.73 m^sup 2^)^sup -1^. The present study analyzes whether these GFR predic...

Applicability of commonly used Caucasian prediction equations for spirometry interpretation in India
Indian Journal of Medical Research ; Background & objectives: The applicability of Caucasian prediction equations in interpreting spirometry data in Indian patients has not been studied. The present study was undertaken to see if Caucasian and north Indian prediction equations can be used interchangeably while interpreting routine

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
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,
