Thallium (Tl) is a non-essential and toxic trace metal found in many plants, but it can accumulate at particularly high concentration in green cabbage (Brassica oleracea L. var. capitata L.). The aim of this study is to explore the transfer and accumulation of Tl at the interface of rhizospheric soil and green cabbage from a long-term Tl contaminated site in southwestern Guizhou Province, China...

reverse redistribution pattern is defined as decreased activity in the myocardium in the rest phase of the myocardial perfusion scan in comparison with the stress images. there are many studies concerning the etiology and clinical significant of this phenomenon in nuclear medicine literature. the dominant idea about etiology of reverse redistribution is early wash out of the radiotracer from th...

Alumina (Al2O3) with an average particle size of 63 μm was modified with the anionic surfactant sodium dodecyl sulfate (SDS) and then applied to (i) solid phase extraction and separation of both thallium(I) and thallium(III), and (ii) preconcentration of Tl(III) from waste water samples. Only Tl(III), in the form of its complex with diethylenetriaminepentaacetate (DTPA), was retained on the sor...

BACKGROUND A link between severe mental stress and shorter telomere length (TL) has been suggested. We analysed the impact of Posttraumatic Stress Disorder (PTSD) on TL in the general population and postulated a dose-dependent TL association in subjects suffering from partial PTSD compared to full PTSD. METHODS Data are derived from the population-based KORA F4 study (2006-2008), located in s...

Telomere length (TL) dynamics in vivo are defined by TL and its age-dependent change, brought about by cell replication. Leukocyte TL (LTL), which reflects TL in hematopoietic stem cells (HSCs), becomes shorter with age. In contrast, sperm TL, which reflects TL in the male germ cells, becomes longer with age. Moreover, offspring of older fathers display longer LTL. Thus far, no study has examin...

The title compound, [Tl(4)(C(4)H(9)O)(4)], featuring a (Tl-O)(4) cube, crystallizes with a quarter-mol-ecule (located on a special position of site symmetry ..) and a half-mol-ecule (located on a special position of site symmetry 23.) in the asymmetric unit. The Tl-O bond distances range from 2.463 (12) to 2.506 (12) Å. All O-Tl-O bond angles are smaller than 90° whereas the Tl-O-Tl angles are ...

BACKGROUND Myocardial viability in area at risk of acute myocardial infarction (AMI) after reperfusion therapy may be underestimated by the 24-hour images due to reverse redistribution (r-RD). METHODS Subjects were 37 AMI patients in whom Tc-99m pyrophosphate (PYP)/Tl-201 dual-isotope SPECT was positive. The 24-hour delayed scan was performed with only a Tl window. One month later, follow up ...

Inorganic thallium compounds in the atmospheric particulate matter of emissions and in the workplace air of specific industrial production can be determined through selective sequential extractions: Tl(I) is separated from Tl(0) and Tl(III) in the first step, Tl(0) in the second one, while in the final extraction both Tl(III) soluble and insoluble compounds are determined. The procedure has bee...

Cancer vaccines that use tumor lysate (TL) as a source of tumor-associated antigens (TAAs) have significant potential for generating therapeutic anti-tumor immune responses. Vaccines encompassing TL bypass the limitations of single antigen vaccines by simultaneously stimulating immunity against multiple TAAs, thereby broadening the repertoire of TAA-specific T-cell clones available for activati...

BACKGROUND AND PURPOSE Increasing thrombus length (TL) impedes recanalization after intravenous (IV) thrombolysis. We sought to determine whether the clinical benefit of aspiration thrombectomy relative to IV r-tPA (recombinant tissue-type plasminogen activator) may be greater at longer TL. METHODS THERAPY was a randomized trial of aspiration thrombectomy plus IV r-tPA versus IV r-tPA alone i...
