Peristaltic Pressure Profiles of the Human Esophagus

Journal of Clinical Gastroenterology, 2000
Using a low-compliance pneumohydraulic infusion system, we mapped the entire esophagus of nine volunteers with no history of esophageal disease, centimeter by centimeter, to see if there was pressure symmetry throughout the esophagus during 5 mL wet swallows. We found that esophageal length varied from 21-25 cm.

Effect of Reduced Pressure on Human Performance

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1967
The purpose of this study was to determine whether reduced pressure (1.5 psi) versus ambient pressure (14.7 psi) had a differential effect on man's performance in a pressurized (3.7 psi) Apollo suit. Two subjects were tested on three different types of tasks: psychomotor, a lunar mission-specific task, and walking.

Heredity and blood pressure in humans: an overview

Pediatric Nephrology, 1987
This paper presents a review of the genetic transmission of normal blood pressure and of essential hypertension. Familial aggregation of normal blood pressure has been reported in adults, in children and even in newborns. Blood pressure aggregation phenomenon, however, is the result of both a genetic component and shared environmental factors.

Pressure of lymphatic capillaries in human skin

American Journal of Physiology-Heart and Circulatory Physiology, 1992
The network of lymphatic capillaries of the human skin was depicted at the distal part of the tibial plateau by fluorescence microlymphography (fluorescein isothiocyanate-dextran 150,000). Intralymphatic pressure was determined in 28 lymphatic capillaries of 21 healthy volunteers (mean diameter 56.0 +/- 10.0 microns) by a servo-nulling pressure system.

Human Arterial Pressure

2007
Abstract The BP is a highly multifactorial variable, meaning that it is influenced by virtually all that goes on in the circulation. This makes it of the utmost value as an indicator of future cardiovascular risk, assuming that it is measured by adequate methodology.

Evolution of blood pressure regulation in humans

Current Hypertension Reports, 2007
The human propensity for hypertension is a product, in part, of our evolutionary history. Adaptation to climate, first in Africa and then throughout the world, has driven our evolution and may have shaped current patterns of hypertension susceptibility.

PERFUSION PRESSURE AND HUMAN KIDNEY PRESERVATION

Transplantation, 1978
From July 1972 to September 1976, 708 kidneys received through the Interhospital Organ Bank, New England were divided into two groups. Both groups were preserved by continuous pulsatile perfusion. Group 1 (308 kidneys) was maintained at a systolic pressure of 60 mm Hg throughout the preservation period.

Salt Sensitivity of Blood Pressure in Humans

Hypertension, 1996
Abstract A variety of different techniques have been used for the assessment of the blood pressure response to changes in salt and water balance in humans. These have generally been found to be reproducible and to yield congruent results.

Pressure-pain threshold in the human tongue.

Journal of orofacial pain, 2001
Aims: A new pressure algometer was used to quantify the pressure-pain threshold (PPT) in the human tongue. Methods: A custom-made device, controlled by software and a personal computer was used to measure the PPT in the anterior part of the tongues of 14 young, healthy subjects.

Osmotic Pressure of Human Sweat

Journal of Applied Physiology, 1957
The osmotic pressure of forearm sweat and of blood serum has been measured in a single individual in 48 sweating experiments involving varied rates of sweating and states of body hydration.
