Two propylene amine oxime (PnAO) complexes, 1, containing a 3-nitro-1,2,4-triazole and 2, containing two 3-nitro-1,2,4-triazoles, were synthesized and radiolabeled with (99m)Tc in high labeling yields. Cellular uptakes of (99m)Tc-1 and (99m)Tc-2 were tested using a S180 cells line. Under anoxic conditions, the cellular uptakes of (99m)Tc-1 and (99m)Tc-2 were 33.7 ± 0.2% and 35.0 ± 0.7% at 4 h, ...

OBJECTIVES QT interval prolongation is prevalent among patients with Takotsubo cardiomyopathy (TC), whereas torsades de pointes (TdP) has rarely been reported in these patients. We studied all peer-reviewed reports on TC-associated QT interval prolongation and all peer-reviewed reports on TC-associated TdP to characterize the clinical circumstances leading to TdP in patients with TC. METHODS ...

Objectives. Studies comparing outcome of single-(99m)Tc-methoxyisobutylisonitrile ((99m)Tc-sestamibi) and dual-tracer (99m)Tc-sestamibi scintigraphy in combination with (123)I before primary surgery of primary hyperparathyroidism (PHPT) are scarce. Methods. We compared (99m)Tc-sestamibi/(123)I and (99m)Tc-sestamibi in a single-centre retrospective series of 269 PHPT patients. The results were r...

Tropical cyclone (TC) size, usually measured with the radius of gale force wind (34 kt or 17m s), is an important parameter for estimating TC risks such as wind damage, rainfall distribution, and storm surge. Previous studies have reported that there is a very weak relationship between TC size and TC intensity. A close examination presented here using satellite-based wind analyses suggests that...

Vitamin B12 (cyanocobalamin, CNCbl) is an essential cofactor-precursor for two biochemical reactions in humans. When ingested, cobalamins (Cbl) are transported via a multistep transport system into the bloodstream, where the soluble protein transcobalamin (TC) binds Cbl and the complex is taken up into the cells via receptor mediated endocytosis. Crystal structures of TC in complex with CNCbl h...

BACKGROUND Germ cell testicular cancer (TC) patients have an increased risk of developing a contralateral TC. This paper presents a retrospective analysis of patients with bilateral TC from a database of a single center and aims to highlight the need for an individual approach. MATERIAL AND METHODS In the study period from January 1970 to June 2013, a total of 1,438 patients with primary TC w...

A Mobile Ad hoc Network (MANET) consists of multiple wireless mobile devices that form a network on the fly to allow communication with each other without any infrastructure. Due to its nature, providing security in these networks is challenging. Threshold Cryptography (TC) provides a promise of securing these networks. In this paper, we discuss our RSA-based Threshold Cryptography (RSA-TC) and...

This study examined longitudinal adoption patterns of tobacco cessation (TC) counseling and TC pharmacotherapy in substance use disorder treatment programs and baseline predictors (program characteristics and program culture) of these patterns 12-months later. Telephone survey data were collected in 2010 from 685 randomly sampled program administrators working in geographically representative t...
