Abstract Cisplatin is a powerful anticancer drug but its nephrotoxic effects limit its clinical use. We aimed to evaluate the effect of mesenchymal stem cells (MSCs) injection or of captopril to counteract the cisplatin-induction of nephropathy. MSCs isolation, preparation and tracking, transforming growth factor-β (TGF-β) and interleukin-10 (IL-10) expressions, kidney function tests, oxidative stress state, and histological examinations were done. Cisplatininduced nephropathy was indicated biochemically and confirmed histopathologically. MSCs treatment showed normal kidney architecture, and significantly decreased oxidative stress and TGF-β while increased IL-10 and improved kidney function tests. Rats treated with cisplatin + captopril showed noticeable kidney histopathological changes. Superior… More >

Abstract An increased interest in the antioxidant effects of medicinal plants has developed in recent years. Identifying antioxidant compounds present in medicinal plants and elucidating the mechanism by which they prevent oxidation have been the focus of the research community. We performed a systematic and exhaustive review aimed at analyzing the available data regarding the beneficial effects of secondary metabolites in plants. The result of this review is presented as a description of free radicals, as well as cellular and physiological oxidative stress, is provided. The origin and source of antioxidant compounds, and the cellular and molecular mechanism by which they… More >

Abstract Fluoride is a key ingredient of many psychiatric drugs like fluoxetine (Prozac^®, Fluoxetine^®). Pregnant women frequently use this drug as they suffer from depression and anxiety disorders during this period. Fluoxetine is able to reach the fetus through the placenta and passes to the newborn through milk. In the present study, female Wistar rats were treated with 5, 10, and 20 mg/L fluoxetine (containing 94% fluorides) from pregnancy day 10 to day 20. After delivery, the levels of the enzymatic antioxidants in the brain of their offspring at postnatal day 2 were measured. The results showed that, in all fluoxetine… More >

Abstract Degraded water quality from nutrient pollution, physical, biological, and other chemical factors contributes to the development and persistence of many harmful algal blooms (HABs). The complex dynamics of the HABs is a challenge to marine ecosystems for the toxic effects reported. The consequences include fish, bird, and mammal mortality, respiratory or digestive tract problems, memory loss, seizures, lesions and skin irritation in many organisms. This review is intended to briefly summarize the recent reported information on harmful marine toxin deleterious effects over the primary organisms of the food web, namely algae, zooplankton and invertebrates. Special focus is made on oxidative… More >

Abstract This study was designed to investigate the effects of mechanical (MS) and/or oxidized low-density lipoprotein on proliferation and apoptosis of RAW264.7 macrophages and the underlying mechanisms. The cultured quiescent RAW264.7 macrophages were subject to stimulation with MS and/or in the presence or absence of simvastatin and then harvested for Western blot, and immunoflourecence. Either MS or alone could cause increase in cell proliferation and apoptosis, while their combination led to an additive effect. In terms of mechanisms, MS and/or significantly increased phosphorylation levels of MAPKs (ERKs, JNKs and p38MAPK), promoted the reactive oxygen species (ROS) and up-regulated DNA methylation in… More >
