The use of topical retinoids to treat skin disorders and ageing can induce local reactions, while oral retinoids are potent teratogens and produce several unwanted effects. This way, efforts to explore complementary care resources should be supported. Based on this, we evaluate the antiageing effects of a supercritical CO2 extract from Bidens pilosa L.(More)
Glioblastoma is the most aggressive primary brain tumor. Surgical resection, radiotherapy and temozolomide (TMZ), an alkylating agent, is the standard of care. Glioma cells may synthetize the antioxidant glutathione by importing cystine through a cystine/glutamate antiporter, which is inhibited by sulfasalazine (SAS). C6 rat glioma cells are largely used in(More)
Temozolomide (TMZ) is an alkylating agent used to treat glioblastoma. This tumor type synthesizes the antioxidant glutathione through system X c − , which is inhibited by sulfasalazine (SAS). We exposed A172 and T98G human glioblastoma cells to a presumably clinically relevant concentration of TMZ (25 µM) and/or 0.5 mM SAS for 1, 3, or 5 days and assessed(More)
