The preparation and characterization of two mononuclear cobalt(III) tropocoronand complexes, [Co(TC-5,5)](BF4) and [Co(TC-6,6)](BPh4), are reported. The cobalt(III) centers exist in rare pseudotetrahedral conformations, with twist angles of 65° and 74° for the [Co(TC-5,5](+) and [Co(TC-6,6)](+) species, respectively. Structural and electrochemical characteristics are compared with those of newl...

We present detailed heat capacity measurements for Ba(Fe1−xCox)2As2 and Ba(Fe1−xNix)2As2 single crystals in the vicinity of the superconducting transitions. The specific-heat jump at the superconducting transition temperature (Tc), ΔCp/Tc, changes by a factor of ∼10 across these series. The ΔCp/Tc vs Tc data of this work [together with the literature data for Ba(Fe0.939Co0.061)2As2, (Ba0.55K0.4...

Tc-99m polyclonal immunoglobulin-G has been shown to be a successful agent in the depiction of active inflammation in rheumatoid arthritis (RA). The objective of this study was to compare the uptake behaviors of Tc-99m HIG and Tc-99m MDP in RA and variants of rheumatoid arthritis (VRA). Seventeen patients with RA and 8 patients with VRA presenting with active inflammation were included in this ...

Thirty patients had bone scintigraphy with both Tc-99m pyrophosphate (Tc-PPi) and Tc-99m diphosphonate (Tc-HEDP). The images were given a composite rating for quality and the basis of three sets of criteria, and were also compared for the number of lesions detected by each agent. The two agents provided no difference in scan quality. Nevertheless, in ten of the 30 patients, at least two of the ...

Aim To study the antiplatelet aggregation of ticlopidine (TC). Methods Using coronary artery Folts model in beagles, the efficacy of TC on platelet aggregation was studied. Results (1)TC16, 32 mg•kg -1 dramatically inhibited the frequency of CFRs dose-dependently, and the times of CFRs decreased by 27%, 56%, 95%, 100% respectively at 1-4 h than that in control group’s after TC 32 mg•kg -1 admin...

BACKGROUND Cognitive decline amongst older adults is a significant public health concern. There is growing interest in behavioral interventions, including exercise, for improving cognition. Studies to date suggest tai chi (TC) may be a safe and potentially effective exercise for preserving cognitive function with aging; however, its short-term and potential long-term impact on physically active...

The aim of this study is to determine the contribution of neck and chest Tc-pertechnetate scan to the management of postoperative patients with suspicious metastatic differentiated thyroid cancer (DTC), particularly to the prediction of response to radioiodine (I) therapy. Just before I administration, a total of 184 postoperative DTC patients with stimulated serum thyroglobulin (ssTg) >10 ng/m...

BACKGROUND Tai Chi (TC) exercise improves balance and reduces falls in older, health-impaired adults. TC's impact on dual task (DT) gait parameters predictive of falls, especially in healthy active older adults, however, is unknown. PURPOSE To compare differences in usual and DT gait between long-term TC-expert practitioners and age-/gender-matched TC-naïve adults, and to determine the effect...

association between the 259R allele and lower concentrations of holo-TC in plasma (8, 21). Nevertheless, holo-TC in CSF was reduced in patients with the 259PR and 259RR genotypes, showing that the polymorphism indeed affected holo-TC concentrations in CNS. Holo-TC concentrations in plasma and CSF were highly correlated, which is compatible with the notion that all holo-TC in CSF originates from...
