The purpose of this study was to compare the effect of different hydrogels on the production of tissue-engineered cartilage based on polyglycolic acid (PGA). Chondrocytes were isolated from adult sheep auricles. Alginate, Type I collagen, methylcellulose, and pluronic F127 hydrogels were evaluated, as were controls prepared without hydrogels. Proliferated(More)
BACKGROUND Despite recent advances in reconstruction techniques, total gastrectomy is still accompanied by various complications. As an alternative treatment, we propose a tissue-engineered stomach that replaces the mechanical and metabolic functions of a normal stomach. The objective of this study was to demonstrate the function of a tissue-engineered(More)
Renal fibrosis is a common pathological consequence of chronic kidney disease (CKD) with tissue fibrosis closely associated with chronic inflammation in numerous pathologies. However, molecular mechanisms underlying that association, particularly in the kidney, remain unclear. Here, we determine whether there is a molecular link between chronic inflammation(More)
Psoriasis is a chronic inflammatory skin disease marked by aberrant tissue repair. Mutant mice modeling psoriasis skin characteristics have provided useful information relevant to molecular mechanisms and could serve to evaluate therapeutic strategies. Here, we found that epidermal ANGPTL6 expression was markedly induced during tissue repair in mice.(More)
1,2,4-Trichlorobenzene (TCB) labeled with C-14 was given perorally to rats at a dosage of 50 mg/kg for excretion and distribution studies. About 66% and 17% of the oral dose was excreted in the urine and feces, respectively, within 7 days. Trapped radioactivity in the expired air amounted to 2.1% of the dose, but production of labeled carbon dioxide was(More)
The metabolic fate of 2-ethylhexyl diphenyl phosphate (EHDPP) was studied in male rats. Orally administered 14C-EHDPP was rapidly absorbed and about 80% of the radioactivity was excreted in the urine and feces in the first 24 h. By 7 days, 48% and 52% of the radioactivity was recovered in urine and feces, respectively. Since biliary excretion was low (6%(More)
A cardioprotective response that alters ventricular contractility or promotes cardiomyocyte enlargement occurs with increased workload in conditions such as hypertension. When that response is excessive, pathological cardiac remodelling occurs, which can progress to heart failure, a leading cause of death worldwide. Mechanisms underlying this response are(More)
