Molecular Mechanisms of Coffee on Prostate Cancer Prevention
BioMed Research International, Volume 2022, Issue 1, 2022., 2022 Prostate cancer (PCa) is one of the most common types of cancer among men, and coffee is associated with a reduced risk of developing PCa. Therefore, we aim to review possible coffee molecular mechanisms that contribute to PCa prevention. Coffee has an important antioxidant capacity that reduces oxidative stress, leading to a reduced mutation in cells.

Heat-Induced Toxicants: Sensory Appeal Distracts Consumers' Attention From Potential Toxicological Risks of Thermally Processed Foods. [PDF]
Food Sci NutrThe central paradox of thermal processing of foods. (A) The application of heat (e.g., frying, baking, grilling) to food initiates complex chemical reactions, most notably the Maillard reaction and thermal degradation of protein, lipids, and carbohydrate. (B) These reactions create a desirable sensory experience characterized by enticing aromas, golden‐

Interactions of norharman and harman with DNA
Nucleic Acids Research, 1977 The interactions of norharman (9H-pyrido [3,4-b] indole) and harman (1-methyl-9H-pyrido [3,4-b] indole) with DNA were studied. DNA caused remarkable fluorescence quenching and change in the absorption spectra of the dyes. Scatchard plots obtained by optical titration gave Kd values of 2.2 X 10(-5)M and 7.7 X 10(-6)M, and apparent numbers of binding ...
