Insulin resistance is an increasingly prevalent condition in humans that frequently clusters with disorders characterized by left ventricular (LV) pressure overload, such as systemic hypertension. To investigate the impact of insulin resistance on LV remodeling and functional response to pressure overload, C57BL6 male mice were fed a high-fat (HFD) or a standard diet (SD) for 9 days and then un...

Triamcinolone acetonide (TAC), a synthetic glucocorticoid, induces cleft palate resulting from poor development of palatal shelves in mice. However, TAC has no effect on medial edge epithelial cells (MEE cells) in secondary palatal shelves. In the present study, we examined the relationship between the pathogenesis of cleft palate and the effects on MEE cells and palatal mesenchymal cells in ra...

On the occasion of the third joint meeting of the Trauma Association of Canada (TAC) and the Australasian Trauma Society, there remain innumerable challenges to be tackled in eradicating preventable death in both our societies. In Canada, the personnel, structure, and processes to take on these challenges currently exist under the auspices of TAC. Healthy, growing, relevant, and especially comm...

Background: Ear keloids form after ear piercing in genetically predisposed young adults, causing cosmetic disfigurement and negative psycho-social impact, reducing quality of life. Total excision leads to loss tissue distorting framework reconstruction restore esthetically pleasant causes scarring more aggressive keloids. Rate recurrence is higher than 80% when surgical alone done. Aims Objecti...

The Tac protein plays a role in high- and low-affinity interleukin 2 (IL-2) receptors. A mutational survey of this molecule identified several small segments in which the binding of IL-2 was particularly sensitive to amino acid substitutions. Two of the segments (residues 1-6 and 35-43) located in the exon 2-encoded region of the molecule overlapped the apparent binding sites of three monoclona...

BACKGROUND Transverse aortic constriction (TAC) operation is used as an experimental model of left ventricular (LV) hypertrophy and LV failure in mice. The severity of LV remodeling or failure may depend on the degree of TAC, but is variable among operated animals. Therefore, we tried to identify the optimal diameter of TAC to create this model with ease and high reproducibility. METHODS AND ...

The aim of this study was to test in vitro the efficacy of TAC, an original G-quadruplex ligand, as a potential radiosensitizing agent for glioblastoma multiforme (GBM). Two human radioresistant telomerase-positive GBM cell lines (SF763 and SF767) were analyzed, with and without TAC treatment, for telomere length, cell proliferation, apoptosis, cell-cycle distribution, gene expression, cytogene...

The interleukin 2 receptor alpha (IL2Ralpha; CD25; Tac) is the prototypic model for soluble receptor studies. It exists in vivo as a transmembrane complete molecule (TM-Tac) on cell surfaces and as a truncated soluble form (sTac; sIL2R alpha). sTac has been used as a serum marker of T cell activation in immune disorders and of tumor burden in Tac-expressing malignancies. In vivo, serum levels o...

The total antioxidant capacities (TAC) of feces of mammalian herbivores and carnivores were compared. TAC were estimated using three different methods: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS*) reduction, 1,1-diphenyl-2-picrylhydrazyl radical (DPPH*) reduction, and ferric reducing antioxidant power (FRAP). TAC of 18 herbivorous species were generally higher with res...

The potential applications of cationic poly(ionic liquids) range from medicine to energy storage, and the development of efficient synthetic strategies to target innovative cationic building blocks is an important goal. A post-polymerization click reaction is reported that provides facile access to trisaminocyclopropenium (TAC) ion-functionalized macromolecules of various architectures, which a...
