A new combined video content protection approach is proposed and experimentally evaluated. In this approach reliability information obtained during watermark extraction process is used for improving the accuracy of traitor tracing procedure.
The effects of low (8.0 mg/l) and normal (80 mg/l) Ca2+ water diets on systolic blood pressure (SBP) and hypertensive plasma activity were studied. At the end of the 16-week experimental period SBP in the low-Ca2+ group of animals was higher than in the control group after the water treatment: 161 sigma 9 and 120 +/- 4 mm Hg respectively. Significant… (More)
We compared the effects of intravenous administration of the calcium-dependent hypertensive factor from the plasma of patients with essential hypertension and of a synthetic heptapeptide with hypertensive activity. Both substances prove to induce prolonged and pronounced elevation of arterial blood pressure.
Injection of a synthetic analog of parathyroid hypertensive factor to WKY rats considerably increases and prolongs pressor response to adrenaline. Synthetic analog injected after adrenaline induces a short-term (3–4 min) and potent (to 250%) rise of arterial pressure. Each subsequent injection of the synthetic analog induces a less pronounced in the… (More)
The authors consider two new attacks on watermarked video specific to HD 60 fps H.264 High and Main profiles: selective I/P frames' removal and zeroing of residuals in B frames. We propose the method of embedding of a readable watermark for H.264 High Profile video robust to such attacks. The video stream is partially decoded removing entropy coding, then a… (More)
High contents of Ca2+ was revealed in thrombocytes' intracellular compartments in patients with essential hypertension. In response to different stimuli, large amount of Ca2+ can be released in the platelets of the patients which makes a considerable contribution to generation of the Ca2+ signal and activation of thrombocytes in cardiovascular diseases.
The arterial pressure was significantly higher in the calcium-deficient group of rats as compared with the normal rats: 150 +/- 7 and 116 +/- 2 mm Hg, resp. The first group of animals had a hypertensive factor in the blood. The hypertensive activity of the calcium-deficient animals was associated with no known pressor agents and was rather similar to Pang's… (More)
After a 10-minute incubation, both the parathyroid hypertensive factor (PHF) and parathyroid hormone (PTH) reduced myocardial contractility and accelerated myocardial relaxation. Effects of the PTH and PHF on myocardial inotropic characteristics were of opposite directions.
