The subsurface behaviour of Tc, a contaminant resulting from nuclear fuels reprocessing, is dependent on its valence (e.g., IV or VII). Abiotic reduction of soluble Tc(VII) by Fe(II)(aq) in pH 6–8 solutions was investigated under strictly anoxic conditions using an oxygen trap (<7.5 · 10 9 atm O2). The reduction kinetics were strongly pH dependent. Complete and rapid reduction of Tc(VII) to a p...

We evaluated the safety and efficacy of transdermal clonidine (TC) in 23 patients with essential hypertension over a two-year period. Fourteen patients achieved control of blood pressure using TC alone. Six patients achieved control with a combination of TC and the diuretic chlorthalidone (CH). Three patients had control with CH alone or did not achieve control with either TC alone or TC plus C...

Thalamocortical (TC) impulses potently influence the sensory neocortex, but the functional impact of individual TC neurons throughout the layers of the cortex has proved difficult to assess. Here we examine, in awake rabbits, the vertical distribution of monosynaptic currents generated in a somatosensory cortical "barrel" column by spontaneous impulses of single, topographically aligned TC neur...

This first clinical prospective study was conducted to use of technetium-99m immunoglobulin G ((99m)Tc-IgG) as compared with autologous (99m)Tc-red blood cells (RBC) in gated blood pool ventriculography. We studied 12 patients who referred to us for a possible diagnosis of liver hemangioma or infection. Six patients underwent gated planar blood pool (GPBP) acquisition using (99m)Tc-RBC and 6 GP...

Background: Patients with Trichotillomania (TC) have an irreversible urge to pull their hair.  This self-mutilation behavior is associated with high level of tension before and a sense of gratification and relief after TC. Objective: To investigate the personality characteristics of patients suffering from TC. Method: The study was performed on 43 TC patients and 43 gender and age-matched non-p...

Radiopharmaceuticals are known to interact with the blood components (i.e. the red blood cells, serum proteins etc) but so far, there have been no data regarding their purely mechanical trapping in thrombi. The experiments presented in this communication provide evidence that the technetium-99m labeled albumin macroaggregate ((99m)Tc-MAA), apparently due to its particle size, can be almost quan...

Here we demonstrated that chemotherapy induced 14-3-3σ expression in tongue cancer (TC) cells and overexpressed 14-3-3σ sensitized TC cells to chemotherapy especially in multidrug resistant TC (MDR-TC) cells. In agreement, 14-3-3σ knockdown enhanced resistance of TC cells to chemotherapy. Mechanically, we found 14-3-3σ physically bound to GSK3β in protein level and the binding inhibited β-caten...

Seven novel bismuth(III)-halide phases, Bi2Cl6(terpy)2·0.5(H2O) (1), Bi2Cl4(terpy)2(k2-TC)2(2) (TC = 2-thiophene monocarboxylate), BiCl(terpy)(k2-TC)2 (3A-Cl), BiBr(terpy)(k2-TC)2 (3A-Br), (3B-Cl), [BiCl(terpy)(k2-TC)2][Bi(terpy)(k2-TC)3]·0.55(TCA) (4), [BiBr3(terpy)(MeOH)] (5), and [BiBr2(terpy)(k2-TC)][BiBr1.16(terpy)(k2-TC)1.84] (6), were prepared under mild synthetic conditions from methano...

PURPOSE: To evaluate the hypothesis that telomere DNA content (TC) in breast tumor tissue correlates with TNM staging and prognosis. EXPERIMENTAL DESIGN: Slot blot assay was used to quantitate TC in 70 disease-free normal tissues from multiple organ sites, and two independent sets of breast tumors containing a total of 140 samples. Non-parametric Rank Sums Tests, Logistic regression and Cox pro...
