The existence of the epicardial telocytes was previously documented by immunohistochemistry (IHC) or immunofluorescence. We have also demonstrated recently that telocytes are present in mice epicardium, within the cardiac stem-cell niches, and, possibly, they are acting as nurse cells for the cardiomyocyte progenitors. The rationale of this study was to(More)
During the last few years, there is an increasing interest in the role of the epicardium in cardiac development, myocardial remodelling or repair and regeneration. Several types of cells were described in the subepicardial loose connective tissue, beneath the epicardial mesothe-lium. We showed previously (repeatedly) the existence of interstitial Cajal-like(More)
This study evaluated the in vitro effects of 62.5 µg/mL silica nanoparticles (SiO NPs) on MRC-5 human lung fibroblast cells for 24, 48 and 72 h. The nanoparticles' morphology, composition, and structure were investigated using high resolution transmission electron microscopy, selected area electron diffraction and X-ray diffraction. Our study showed a(More)
The ability of naringenin (NGN) to protect the kidney against CCl4-induced renal toxicity in male Swiss mice was investigated. The flavonoid was given orally to mice for 7days and then on the 8th day, these were intraperitoneally injected with 10mmol/kg CCl4. When the toxicant was administrated alone, an increase of malondialdehyde (MDA) concentration was(More)
We investigated the protective effect of chrysin on chronic liver fibrosis in mice and the potential mechanism underlying TGF-β1-mediated hepatic stellate cells (HSCs) activation on fibrogenesis. Experimental fibrosis was established by intraperitoneal injection of mice with 20% v/v, 2 ml/kg CCl4 twice a week, for 7 weeks. Mice were orally treated with 3(More)
The main purpose of this study was to certify the effect of native silymarin oil (SM-oil) formulated in a self-microemulsifying drug delivery system (SMEDDS). The optimal formulation was 25% of SM-oil, 33.3 % of Cremophor RH40, 20% of Transcutol HP, 16.6% of Labrasol and 5% of Capryol 90. In this novel formulation the SM-oil was the active substance and the(More)
Extensively studied nowadays, graphene oxide (GO) has a benefic effect on cell proliferation and differentiation, thus holding promise for bone tissue engineering (BTE) approaches. The aim of this study was not only to design a chitosan 3D scaffold improved with GO for optimal BTE, but also to analyze its physicochemical properties and to evaluate its(More)
The present study investigated the capacity of formulated Berberis vulgaris extract/β-cyclodextrin to protect liver against CCl(4)-induced hepatotoxicity in mice. Formulated and non-formulated extracts were given orally (50 mg/kg/day) to mice for 7 days and were then intra-peritoneally injected with 1.0 mL/kg CCl(4) on the 8th day. After 24 h of CCl(4)(More)
Trigonella foenum-graecum (TFG) seeds exert a protective antioxidant effect and membrane protector through their rich content in polyphenolic flavonoids. The previous research focused on the hypoglycemic action of the seeds, with scarce studies on the preventive effects in the pathology of the kidney. Our work was conducted on an experimental in vivo model;(More)
Magnetite nanoparticles (MNP) have attracted great interest for biomedical applications due to their unique chemical and physical properties, but the MNP impact on human health is not fully known. Consequently, our study proposes to highlight the biochemical mechanisms that underline the toxic effects of MNP on a human lung fibroblast cell line (MRC-5). The(More)
