E. coli and gut health—For the loser now will be later to win

The FEBS Journal, EarlyView.
In humans, commensal gut bacteria participate in a miniature nitrogen cycle, metabolizing dietary nitrate and nitrite. While these processes can generate harmful N‐nitrosamines, they may also produce beneficial nitric oxide (NO) or ammonium. Hager and colleagues demonstrate that E.

Endogenous N-nitroso compounds, and their precursors, present in bacon, do not initiate or promote aberrant crypt foci in the colon of rats [PDF]

, 2000
Processed meat intake is associated with increased risk of colorectal cancer. This association may be explained by the endogenous formation of N-nitroso compounds (NOC).

Conventional cigarettes, novel heated tobacco products, and self‐reported frequent headache association in Japanese individuals: Insights from the JASTIS study, a Japanese cross‐sectional analysis

Headache: The Journal of Head and Face Pain, EarlyView.
Plain Language Summary Headache is a common health problem, and tobacco products, such as conventional cigarettes and heated tobacco products (HTPs), may be associated with it. Using data from over 23,000 adults in the Japan Society and New Tobacco Internet Survey, we examined the relationships between cigarette and HTP use and self‐reported frequent ...

Understanding N-nitrosodimethylamine Formation in Water: Chloramine Chemistry, Kinetics, and A Proposed Reaction Pathway [PDF]

, 2017
The formation of N-nitrosodimethylamine (NDMA) in drinking water systems is a concern because of its potential carcinogenicity and occurrence at toxicologically relevant levels.

Vaginal Microbiota and Ovarian Cancer: A New Frontier in Immunomodulation and Diagnosis

Immunology, EarlyView.
Microbial imbalance, dysbiosis, plays a role in ovarian carcinogenesis by interacting with the immune system and altering inflammatory pathways, notably Th17 pathways. In contrast, eubiosis, characterised by Lactobacillus dominance, protects against infections and maintains hormone metabolism.

Evaluation of N-Nitrosamine Formation in Routine Potato Cooking [PDF]

, 2015
Background: Nitrosamine is amongst carcinogen chemical compounds, which can enter the human body through consumption of food. Potatoes are a root vegetable consumed by many people around the world, however their potential for nitrosamine formation during

Estimated Exposure Risks from Carcinogenic Nitrosamines in Urban Airborne Particulate Matter [PDF]

, 2015
Organic nitrogen (ON) compounds are present in atmospheric particulate matter (PM), but compared to their inorganic, hydrocarbon and oxygenated counterparts, they are difficult to characterize due to their complex chemical composition. Nitrosamines are a
