Perfluorooctanoic acid (PFOA) is widely present in the environment and has been reported to induce hepatic toxicity in animals and humans. In this study, mice were orally administered different concentrations of PFOA (2.5, 5, or 10 mg/kg/day). Histological examination showed that the exposure to PFOA for 14 consecutive days led to serious hepatocellular(More)
PURPOSE To investigate if there is an effect of sustained trunk axial twisting on the development of low back pain. METHODS Sixteen male pain-free university students volunteered for this study. The trunk axial twisting was created by a torsion moment of 50 Nm for 10-min duration. The axial rotational creep was estimated by the transverse camera view(More)
These experiments were performed to know whether sanjoinine A, a component of the alkaloid fraction of Semen Zizyphi Spinosi, acts as an anti-convulsive agent in the kainic acid (KA)-induced experimental convulsion model and whether these effects are mediated by decreased intracellular calcium. Oral administration of sanjoinine A (4 and 8 mg/kg) increased(More)
To examine whether an engineered tendon matrix (ETM) environment and growth and differentiation factor-6 (GDF-6) have synergistic effects on the tenogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and the quality of tendon repair. ETM and GDF-6 promote tenogenic differentiation of BMSCs in vitro. Implantation of GDF-6-incorporated ETM(More)
Transplantation of ligament-tissue-derived stem cells has become a promising approach in the repair of injured ligament. Neovascularization plays an important role in ligament healing and remodeling. Recently, human umbilical-cord-blood-derived CD34+ cells have been reported to contribute to neoangiogenesis. Therefore, we performed a series of experiments(More)
Tendon stem cells (TSCs), recently identified as tendon cells, play an important role in maintaining the homeostasis of tendon tissue. Age-related decrease in the function of TSCs has been reported. Recent reports demonstrated that hypoxic condition is advantageous for efficient expansion of TSCs. Moreover, the impaired function of aged stem cells could be(More)
Investigations corresponding to the affected factors of the cross-correlation of pair muscles are limited though muscle activation patterns of bilateral erector spinae (ES) during trunk flexion-extension performance in standing have been utilized as an indicator in the evaluation of low back pain condition. The purpose of the study is to evaluate the effect(More)
BACKGROUND Local anesthetics are commonly used for the treatment of a variety of tendinopathies in combination with corticosteroids injection. The goal of this study was to evaluate the effects of lidocaine and triamcinolone acetonide (TA) on cultured rat tenocytes and to determine whether there is a synergistic effect. MATERIAL/METHODS Rat patellar(More)
Adult rats were implanted with sleep-wake recording electrodes in our experiments. Polygraphic signs of undisturbed sleep-wake activities were recorded for 24 h before cocaine administration, cocaine withdrawal day 1 (acute), day 8 (subacute), and day 14 (subchronic). Western blot method was performed to examine the expression levels of adenosine receptor(More)
This study attempted to clarify whether cocaine withdrawal altered sleep architecture and the role of adenosine receptors in this process. Cocaine (20 mg/kg) was administered subcutaneously once per day for 7 days to rat implanted with sleep/wake recording electrode. Polygraphic signs of undisturbed sleep/wake activities were recorded for 24 h before(More)
