Chemotaxis Response to Redox Potential

Response of S. typhimurium to mixed Cys / CySS solutions. Dependence of the initial amplitude of the FRET response, ΔFRETI, of WT S. typhimurium LT2 to the redox potential expressed in units of log Q, where Q is the reaction quotient of Cys / CySS interconversion. A Hill equation fit (with Hill coefficient of 2 and half-maximum of 51) is shown for guidance of the eye. The grey line at 0 divides attractant (negative) and repellent (positive) responses. Artist representations…

Blood Pressure Regulation by Oral Microbiome

The effect of beetroot juice on blood pressure 1. You swallow the nitrate-rich beetroot juice. 2. The nitrate (NO3−) content is taken up by your intestine into your blood and transported to your salivary glands. 3. Your salivary glands actively fish out the nitrate of your blood and concentrate it to high levels (4-8 mM) into your saliva. 4. The bacteria in your mouth reduce the nitrate in your saliva to nitrite (NO2−). 5. (a) Your saliva, which is now…
