The development of therapeutic strategies to attenuate chemotherapy toxicity represents an area of great interest in cancer research, and among them is nutritional therapy based on antioxidants. As research on this topic is still controversial and scarce, we aim to investigate the effects of
This work aimed to test a dextran-functionalized magnetic fluid (DexMF) sample in mediating magnetohyperthermia to treat an advanced clinical Ehrlich-solid-tumor, to verify the effects of oral antioxidant administration of pequi-oil on this treatment and to investigate the potential of these
Strong evidence indicates that reactive oxygen species (ROS) play an important role in the initiation as well as the promotion phase of carcinogenesis. Studies support the role of ROS in cancer, in part, by showing that dietary antioxidants act as cancer-preventive agents. Although results are
The cytotoxicity of extracts obtained from plants occurring in the Amazon and Atlantic rain forests against NCI-H460, KM-12, SF-268 and RPMI-8226 cancer cell lines was investigated. Expressive activity was observed in the extracts of Toulicia cf. pulvinata, Ampirrhox sp., Macoubea sprucei,
Pequi (Caryocar brasiliense Camb.), a fruit from Brazil's central region, was evaluated for its chemopreventive effects on preneoplastic liver lesions induced by the carcinogen diethylnitrosamine (DEN) in mice. BALB/c mice, 14 days of age, received an intraperitoneal injection at 10 µg/g of DEN. The
Carbon tetrachloride (CCl4) is a potent hepatotoxin, capable of generating free radicals that lead to oxidative stress and the inflammation process. Pequi almond oil (PAO) has been reported to possess unsaturated fatty acid and antioxidant compounds related to beneficial effects on oxidation and
Several plant species are traditionally used in Brazil to treat various inflammatory diseases. Tumor necrosis factor- (TNF-) α and chemokine (C-C motif) ligand 2 (CCL2) are key inflammatory mediators in diseases like rheumatoid arthritis and atherosclerosis, respectively; nevertheless, only a few
BACKGROUND
Traditional medical systems represent an important source of knowledge about the use of biodiversity. Ethnobotanical and ethnopharmacological studies can encourage bioprospecting in the pursuit and selection of promising medicinal plants. This study investigated the diversity of medicinal
