Colorectal Carcinogenesis: Role of Oxidative Stress and Antioxidants

2017

One of the contributory causes of colon cancer is the negative effect of reactive oxygen species on DNA repair mechanisms. Currently, there is a growing support for the concept that oxidative stress may be an important etiological factor for carcinogenesis. The purpose of this review is to elucidate the role of oxidative stress in promoting colorectal carcinogenesis and to highlight the potential protective role of antioxidants. Several studies have documented the importance of antioxidants in countering oxidative stress and preventing colorectal carcinogenesis. However, there are conflicting data in the literature concerning its proper use in humans, since these studies did not yield defin…

Microbiota e HPV nel carcinoma orale

2021

La carcinogenesi è un processo multifattoriale in cui sono coinvolti differenti fattori esogeni; tra questi, il microbiota sembra svolgere un ruolo attivo nei mec- canismi di sviluppo del carcinoma orale [1]. Nella presente trattazione saranno descritti i principali aspetti epidemiologici, clinici e patogenetici che vedono coinvolto il microbiota orale nel processo di carcinogenesi omodistrettuale. A tal proposito, per facilità di trattazione, è stata condotta una distinzione del microbiota orale in due gruppi: microbiota orale batterico e microbiota orale non batterico (i.e. Candida spp, Human Papilloma Virus). Fra i microrganismi appartenenti a quest’ultimo gruppo, verrà condotta una disa…

Nutrition in inflammatory bowel disease patients

2015

Inflammatory Bowel Diseases (IBD) is a chronic disorder characterized bya relapsing-remitting course, which alternates between active and quiescent states, ultimately impairing a patient's quality of life. The two main types of IBD are Crohn's disease (CD) and ulcerative colitis (UC). CD shows a transmural granulomatous inflammation that can involve any segment of the intestine affecting all layers of the intestinal wall while UC is limited to the mucosa and superficial sub-mucosa of the colon. In physiologial conditions the gut is costantly exposed to various antigens, commensal microflora and pathogens and the inflammatory response is finely balanced. Anyhow in some individuals with genet…
