Anticancer and Anti-Inflammatory Activities of Some New Pyrazolo[3,4-b]pyrazines

Molecules, 2018
New derivatives of pyrazolo[3,4-b]pyrazines and related heterocycles were synthesized using 5-amino-3-methyl-4-nitroso-1-phenyl-pyrazole (1) as a starting material. The 5-acetyl derivative 15 was shown to be a useful key intermediate for the synthesis of

Retinoic Acid Signalling Regulates Zebrafish Tooth Germ Repair Following Injury

Cell Proliferation, EarlyView.
Retinoic acid signalling may regulate the repair processes in a tooth germ injury model using Tg(scpp5:Dendra2‐NTR) zebrafish and the nitroreductase (NTR)/metronidazole (MTZ) system. ABSTRACT Although the role of retinoic acid (RA) signalling in odontogenesis is well established, its involvement in the repair of injured tooth germs remains unclear.

Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

The FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

Freeze-Dried Ham Promotes Azoxymethane-Induced Mucin-Depleted Foci and Aberrant Crypt Foci in Rat Colon [PDF]

, 2010
Processed and red meat consumption is associated with the risk of colorectal cancer. Meta-analyses have suggested that the risk associated with processed meat is higher. Most processed meats are cured and cooked, which leads to formation of free nitrosyl

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

Journal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.
