The effect of exercise on cholesterol metabolism in mice was quantitatively studied after the administration of 4-C14 labelled cholesterol. The distribution of isotope in the sterol and saponifiable fractions of liver and excreta was determined after periods from 3 to 21 days. It was observed that exercise stimulated [1] the degradation of cholesterol, in(More)
A built-in I/sub DDQ/ monitor for CMOS digital circuits with low power supply voltage perturbation is presented. It minimizes the extra delay of the CUT in normal operation. An automatic recovery mechanism limits the drop in VDD voltage during the testing phase so the data storage is not perturbed. The I/sub DDQ/ current level may be measured by a standard(More)
With increasing integration levels, more and more ICs and systems-on-chip turn into mixed-signal designs. Typical examples are telecom (Bluetooth, WLAN, xDSL…) and multimedia (digital video, MP3 audio…) systems. This hot topic session will explore the challenges that designers face with these mixed-signal designs, covering both technical and methodological(More)
By means of a technic published in this journal (2, 66 [1946]), it has been observed that the activity of the pseudo-choline esterase of the serum is highest in presence of high concentrations of acetylcholine. The true choline esterase of the red corpuscules has her optimal activity at concentrations of 200 mg % acetylcholine. This high activity of these(More)
