There are two homologous thyroid hormone (TH) receptors (TRs α and β), which are members of the nuclear hormone receptor (NR) family. While TRs regulate different processes in vivo and other highly related NRs regulate distinct gene sets, initial studies of TR action revealed near complete overlaps in their actions at the level of individual genes. Here, we assessed the extent that TRα and TRβ ...

Parasitic protozoa belonging to the order Kinetoplastida contain trypanothione as their major thiol. Trypanothione reductase (TR), the enzyme responsible for maintaining trypanothione in its reduced form, is thought to be central to the redox defence systems of trypanosomatids. To investigate further the physiological role of TR in Leishmania, we attempted to create TR-knockout mutants by gene ...

Solid triclosan/cyclodextrin inclusion complexes (TR/CD-IC) were obtained and then incorporated in poly(lactic acid) (PLA) nanofibers via electrospinning. α-CD, β-CD, and γ-CD were tested for the formation of TR/CD-IC by a coprecipitation method; however, the findings indicated that α-CD could not form an inclusion complex with TR, whereas β-CD and γ-CD successfully formed TR/CD-IC crystals, an...

Let $A$ be an $m\times m$ positive semidefinite block matrix with each being $n$-square. We write $\mathrm{tr}_1$ and $\mathrm{tr}_2$ for the first second partial trace, respectively. In this paper, we prove following inequality \[ (\mathrm{tr} A)I_{mn} - (\mathrm{tr}_2 A) \otimes I_n \ge \pm \bigl( I_m\otimes (\mathrm{tr}_1 -A\bigr).\] This is not only a generalization of Ando's result [ILAS C...

The transcription of four members of the Kunitz proteinase inhibitor (KPI) gene family of white clover (Trifolium repens L.), designated as Tr-KPI1, Tr-KPI2, Tr-KPI4 and Tr-KPI5, was investigated at both local infection (roots) and systemic (leaf tissue) sites in white clover in response to infection with the clover root knot nematode (CRKN) Meloidogyne trifoliophila and the clover cyst nematod...

Trace levels of PAH pollutants are difficult to detect in water samples due to their low solubility. During this study, SPE method was used to improve the detection of the PAH analytes. A Visipre SPE vacuum manifolds sample preparation method was used to clean-up the river water samples before analysis. Twelve samples were simultaneously extracted via the unit. This method is generally faster a...

We report here the design and construction of several gene vectors for expression in mammalian cells of membrane-bound and soluble human T cell receptors (TR). We designed a vector (TR-ALPHA-IRES-TR-BETA pEF4) that encodes high-level expression of the full-length TR on the surface of T cells. Furthermore, we engineered TR that does not require the presence of endogenous CD3 molecules for surfac...

Our objective was to develop criteria to identify patients with traumatic brain injury (TBI) who require a tracheostomy (TR). From January 1994 to May 2000 all TBI patients requiring intubation on presentation and who survived >7 days were identified from our trauma registry. Demographics, Glasgow Coma Score (GCS), Injury Severity Score (ISS), and ventilator days, ICU days, hospital days, need ...

The response of plants to water deficiency or drought is a complex process, the perception of which is triggered at the molecular level before any visible morphological responses are detected. It was found that different groups of plant proteinase inhibitors (PIs) are induced and play an active role during abiotic stress conditions such as drought. Our previous work with the white clover (Trifo...
