As the rcsults of pul~lishcd investigations on concurrent application of carcinogenic agents and irradiation with ultraviolet, visible and infrared light (2, 6-8, 10-19) differ considerably, wc have found it of in?.crcst to investigate the activity of different carcinogenic hydrocarbons after ultraviolet irradiation. Cook and Martin (~), Dufraisse and Gerard (9) and Vel|uz (20) have shown that ...

Regulatory authorities worldwide have found the nonnutritive sweetener, sucralose, to be noncarcinogenic, based on a range of studies. A review of these and other studies found through a comprehensive search of electronic databases, using appropriate key terms, was conducted and results of that review are reported here. An overview of the types of studies relied upon by regulatory agencies to a...

The products of hexavalent chromium [Cr(VI)] reduction by glutathione (GSH) alone or in the presence of equimolar quantities of aspartate (Asp) and/or glutamate (Glu) and a chromium-containing material extracted from bovine liver were studied by ultraviolet-visible spectrum (UV-vis) studies, electrospray mass spectrometry (ES-MS), electron paramagnetic resonance (EPR), and nuclear magnetic reso...

Lung cancer is the leading cause of cancer death for male and the second most usual cancer for women after breast cancer. Currently there are available several non-specific cytotoxic agents and several targeted agents for lung cancer therapy. However; early stage diagnosis is still unavailable and several efforts are being made towards this direction. Novel biomarkers are being investigated alo...

The role of the retention of carcinogenic hydrocarbons in tis sues in earcinogenesis was demonstrated. Possible contamination of food with carcinogenic hydrocarbons is discussed and the measures for its prevention are planned. Much attention was given to the study of the exhaust gases of cars and to the preven tion of their carcinogenic action. The distribution of benz(a)pyrene in human environ...

The Polarographie reduction of a series carcinogenic and noncarcinogonic polycyclic nitrogen compounds in anhydrous dimetbylsulfoxidc containing tetrabuthylammonium Perchlorate as supporting electrolyte has been studied. The obtained results were compared with the number or with the position of nitrogen atoms in the molecules and with their carcinogenic activity. The values of half-waves potent...

Gastric cancer is the second most common malignancy in the digestive system and the second leading cause of cancer-related death worldwide. Epidemiological data and experimental studies have identified several risk factors for gastric cancer, including Helicobacter pylori infection, low fruit and vegetable intake, N-nitrosoamine exposure, high salt diet, and smoking. Among these risk factors, H...

A review of the progress made in the study of the carcinogenic properties of chemical compounds, incorporating literature published during the triennial period between the First and Second International Cancer Congresses, was presented to the Second International Congress in Brussels, in September 1936, and was subsequently reprinted with an addendum covering most of the literature published up...
