Ultra-low doses of melafen affect the energy of mitochondria

Addition of the organophosphorous plant growth regulator - melafen to the mitochondria incubation medium resulted in modification of energy thereof. The modification was dose dependent one. The melafen concentrations 2 × 10-12, 2 ×10-18 and 2 × 10-21 Ðœ raised the maximum rates for oxidation of NAD+-dependent substrates, elevated the efficiency of oxidative...

Determination of instantaneous arterial blood pressure from bio-impedance signal

The objective of this study was to determine the instantaneous arterial blood pressure by the peripheral bio-impedance. To achieve this goal, the equation of Ben Salah and Flaud, initially meant to determine the instantaneous aortic pressure according to the signal of thoracic bioimpedance, was successfully applied for the determination of the instantaneous arterial pressure according to the signal of peripheral...
