The 16-bit 8086 microprocessor introduces to MOS digital design some speed-up techniques well-known to computer architects. Limits on the die size barred these techniques in the past, but with new MOS processes, transistor packing densities are sufficent to use them. As a result, we have been able to design significantly improved performance into the 16-bit 8086 without relying totally on the faster circuits allowed by the new MOS processes.

Head-up tilt, a recognised stimulus to vasovagal syncope, was used to investigate syncope that remained unexplained despite full clinical and electrophysiological assessment in fifteen patients, mean age 65 ± 10 years, who had had 15 ± 19 episodes of unexplained syncope over periods of a week to 26 years. After overnight fast systolic blood pressure and heart rate were continuously monitored during 40° head-up tilt for 60 min. Ten control subjects with no history of syncope were studied similarly. In ten patients (67%) and one control vasovagal syncope developed after 29 ± 19 min (p < 0·001). In symptomatic patients systolic blood pressure fell from 150 ± 32 to 56 ± 9 mm Hg (p < 0·001) and heart rate from 62 ± 9 to 38 ± 12 beats per min (p < 0·01). In each case symptoms during the test reproduced those previously experienced. No clinical findings predicted development of syncope during tilt. Baseline systolic blood pressure and heart rate did not differ significantly between patients and controls. Pacemakers were implanted in seven patients who have remained symptom-free since implant (follow-up 10 ± 3 mo).

Summary This paper provides the results of studies which characterized conductive36Cl- flux in basolaterally enriched membrane vesicles prepared from rabbit renal outer medulla. Conductive36Cl- uptake was studied under two different experimental conditions. In the first,36Cl- flux was driven by an inside positive voltage created with oppositely directed Cl- and gluconate gradients. In the second, an inwardly direct K+ gradient was used to drive36Cl- uptake. By these two methods, voltage-sensitive36Cl- uptake was shown to comprise about 45 and 65%, respectively, of the initial rates of total36Cl- flux. Separate paired studies demonstrated that the conductive36Cl- uptake was inhibited by the Cl- channel blocker diphenylamine-2-carboxylate (DPC) with an IC50 for DPC of 154 µm. The voltagedependent36Cl- uptake had an activation energy of 6.4 kcal/mole. This36Cl- conductance had an anion selectivity sequence of I->Cl-?NO3-»gluconate.
