Solar ultraviolet radiation (UV) is a major cause of non-melanoma skin cancer in humans. Photochemoprevention with natural products represents a simple but very effective strategy in the management of cutaneous neoplasia. The study investigated the protective activity of Calluna vulgaris (Cv) and red grape seeds (Vitis vinifera L, Burgund Mare variety) (BM)(More)
Environmental iodine deficiency continues to be a significant public health problem worldwide. On the other hand, iodide excess results principally from the use of iodine-containing medicinal preparations or radiographic contrast media. For this reason we intended to explore iodide excess impairment on prooxidant/antioxidant balance of the thyroid gland,(More)
The study investigated the protective activity of red grape seeds (Vitis vinifera L, Burgund Mare variety) (BM) extracts in vivo on multiple doses of ultraviolet radiation (UV)-B-induced deleterious effects in SKH-1 mice skin. Eighty 8-weeks-old female SKH-1 mice were divided into 8 groups: control, vehicle, UV-B irradiated, vehicle+UV-B irradiated, BM(More)
Liver fibrosis, a common condition occurring during the evolution of almost all chronic liver diseases, is the consequence of hepatocyte injury that leads to the activation of Kupffer cells and hepatic stellate cells (HSC). Silymarin (Si) is a herbal product widely used for its hepatoprotective potential. Our study aims to investigate the effects of two(More)
We aimed at investigating the antioxidant, antiinflamatory, antiapoptotic and antigenotoxic effects of a Romanian Propolis (RP) extract in two concentrations (RP1 3 mg, respectively RP2 1.5 mg polyphenols/cm(2)), topically administered, either prior to or after UVB exposure, in a Swiss mouse model. Our results showed that both concentrations of RP extract,(More)
UVB is a major cause of nonmelanoma skin cancer in humans. Photochemoprevention represents an important strategy in protecting the skin against the detrimental effects of ultraviolet B (UVB). We investigated the activity of Calluna vulgaris (Cv) delivered via a hydrogel on 3 main pathways (oxidative stress, inflammation, DNA damage) on skin exposed to(More)
In the early stages of cholestasis, a plethora of mechanisms are considered to contribute to the liver injury: oxidative stress, inflammation, cholangiocytes proliferation and fibrosis. Our study aims to investigate the effects of different doses of rosuvastatin (Ro) on experimental bile duct ligation-induced cholestasis. 40 female Wistar rats were randomly(More)
Multi-walled carbon nanotubes (MWCNTs) are widely used for nanotechnology. Their impact on living organisms is, however, not entirely clarified. Oxidative stress and inflammation seem to be the key mechanisms involved in MWCNTs' cytotoxicity. Until present, pulmonary and skin models were the main tested experimental designs to assess carbon nanotubes'(More)
Nanosized particles (NPs) have recently been proposed for extensive use, including into the biomedical field. As a result, research on toxicity and oxidative stress concerning the interaction of nanoparticle and the living organism has attracted increasing interest among specialists. Two different targets have been the motor of this type of research: 1) the(More)
Aluminum (Al) and indium (In) have embryotoxic, neurotoxic and genotoxic effects, oxidative stress being one of the possible mechanisms involved in their cytotoxicity. We have recently demonstrated that indium intraperitoneal (ip) administration induced histological disorganization of testicular tissue. In the present research we aimed at investigating the(More)
