An automatic procedure providing information about human systolic blood pressure at each successive heartbeat under routine laboratory conditions is described. Twenty normal male subjects were given feedback of their own pressure, half operantly reinforced for increasing and decreasing pressure. Significant differences in obtained a single session. The apparatus results suggest possible approach to the treatment essential hypertension.

Abstract Blood pressure is one of the most commonly recorded functions in physiology and medicine, it has become a major variable recent psychophysiological behavioral medicine research. Many methods have been developed for measurement blood clinical, laboratory, natural settings. The broad objectives this report are to summarize critical methodological issues present principles recommendations evaluation findings published studies.

Human heart rate-systolic blood pressure decoupling was tested by operant conditioning procedures. Twenty normal male subjects were given feedback of their rate, half operantly reinforced for increasing and decreasing while systolic continuously monitored. Significant rate obtained in a single session without concomitant effects on pressure. Further analyses the best conditioners present study those previous indicate strength rate-blood demonstrate that instrumental fractionation closely...

Twelve experimental subjects were given analogue visual feedback and monetary rewards for increase diameter as measured by a strain gauge. no noncontingent but same instructions to maximize erections. While both groups capable tumescence, significantly improved performance was observed group. Two distinct psychophysiological patterns observed. A "tension" pattern associated with marked...

ABSTRACT When provided with external feedback of their diastolic blood pressure and incentives to respond appropriately, normal male Ss learned raise or lower in a 35‐min training session. The difference between increase decrease groups at the end conditioning was 7.0 mm Hg 10% baseline. This augmented 10.4 15% baseline during extinction when half were asked maintain continuing “voluntary control” even though withdrawn. Heart rate also influenced reinforced, although less markedly.

Primary sclerosing cholangitis (PSC) is a rare autoimmune bile duct disease that strongly associated with immune-mediated disorders. In this study, we implemented multitrait joint analyses to genome-wide association summary statistics of PSC and numerous clinical epidemiological traits estimate the genetic contribution each trait correlations between identify new lead risk-associated loci. We identified seven loci have not been previously reported one independent variant in locus. Functional...

Abstract In this study, we examined the combined effects of anger/hostility and defensiveness on reactivity to three stressors (math, handgrip, cold pressor) how these are moderated by gender family history hypertension. The subjects were 209 college students. Low compared with high Spielberger anger‐out scores associated greater diastolic blood pressure (DBP) in low‐but not high‐defensive women a negative history. High low hostility heart rate low‐defensive men an opposite effect men....

In previous research, it has been shown that subjects can learn to increase or decrease their systolic blood pressure without corresponding changes in heart rate, they rate pressure. The present paper outlines a method for directly conditioning combination of two autonomic responses. A system was developed which, at each cycle, determines on line whether and are integrated (both increasing both decreasing) differentiated (one one decreasing). To test this method, 5 received brief light tone...
