Cancer is one of the leading causes of death worldwide. Over the years, a number of conventional cytotoxic approaches for neoplastic diseases has been developed. However, due to their limited effectiveness in accordance with the heterogeneity of cancer cells, there is a constant search for therapeutic approaches with improved outcome, such as immunotherapy that utilizes and enhances the normal capacity of the patient's immune system. ⋯ In this review, the basic design of CARs, the main genetic modification strategies, the safety matters as well as the initial clinical experience with CAR T-cells are described.

Case ReportsNon-fatal Overdose with U-47700: Identification in Biological Matrices.
We report on a case of severe intoxication after insufflation of U-47700, a synthetic opioid that acts as a selective agonist of the μ-opioid receptor, and is several times more potent than morphine. A man in his 30s was found irresponsive in his apartment and was brought to the emergency department of a local hospital. A comatose state and severe respiratory depression were present. Hetero anamnesis revealed that the patient could have taken the substance named "U-47700", bought on the Internet. After supportive care, the patient fully recovered. ⋯ The toxicological findings confirmed the use of U-47700 in the intoxicated patient and also revealed a history of a poly-drug use. The use of LC-HRMS allowed the easy identification of the NPS and its metabolites in fluids and hair.
