    Carcinogenesis is a complex and multistep process ending with metastasis. Mainly, gene and metabolic pathways include endogenous and signaling molecular pathways which cause a rise in cell proliferation and a decrease in cell death. Apoptosis is a programmed cell death which can happen with extracellular and intracellular signals. Generally, the extrinsic and the intrinsic pathways are known as the two apoptotic pathways. The excessive ROS production in cancer cells can stimulate the cell proliferation, the DNA mutations, and the formation of drug-resistant cells. It may also ensure a basisfor thedevelopment of novel therapeutic strategies that take advantage of overgenerating ROS to destroy cancer cells. As the ROS-producing agents have toxic side effects and potential mutagenic impact, caution should be exercised during their use. In this chapter, focus will be on ROS generation, the relationship between apoptosis and ROS, and the key apoptotic mechanisms and their regulations.KeywordsApoptosisReactive oxygen speciesCancer cellsCarcinogenesis

    Ice cream is a kind of dessert consumed with various flavors. However, considering the nutrients of ice creams, it seems to be a good environment for the propagation of microorganisms. Therefore, it was aimed to determinate the microbiological quality of ice creams sold in the open according to Turkish Food Codex on Microbiological Criteria Regulation in this study. Microbiological quality of ice cream samples was evaluated in terms of public health risks and food unsafety which may occur during the production, storage and sales of ice creams. Seventy-five ice cream samples flavored with plain, fruit, and nuts were collected aseptically from 25 enterprises in Istanbul, Türkiye. The presence or absence and enumeration of Total Mesophilic Aerobic (TMA) bacteria, Enterobacteriaceae, Staphylococcus aureus and Salmonella spp. were investigated using related media. The results were evaluated according to the Turkish Food Codex on Microbiological Criteria Regulation. S. aureus found in some ice cream samples was examined for antibiotic resistance against 7 different antibiotics. About a third of all ice cream samples (32%; n=8) from 25 enterprises were found as ‘safe’ in accordance with the Turkish Food Codex on Microbiological Criteria Regulation in terms of public health. The TMA bacteria was determined %88 (n=22) in plain ice creams, %64 (n=16) in fruit ice creams and %92 (n=23) in nuts ice creams. Enterobacteriaceae were found 40% (n=10) of plain ice creams, 12% (n=3) of fruits and 40% (n=10) of nuts. Multiple antibiotic resistance was determined for S. aureus in only one enterprises\"s nuts flavored ice cream. Salmonella spp. was not found in any of collected ice cream samples. Ice creams sold in the open was seen that the microbiological quality of less than half of the enterprises was not at the desired level. Possibly, the unhygienic conditions of production, transportation and sale are eroding the food safety of this delicious dessert. According to the findings of our study, the high prevalence of microbial contamination in ice cream sold in the open may poses a risk to public health. Keywords: Ice cream, microbiological quality, public health, food safety.
