This study was designed to test the hypothesis that postsuspension cardiovascular manifestation in conscious rats after a medium-term (28-day) tail suspension (SUS) is hypertensive and tachycardiac and can be prevented by a countermeasure of daily 1-h dorsoventral (-G(x)) gravitation provided by standing (STD). To assess associated changes in cardiovascular(More)
Most of magnetic resonance imaging (MRI) studies about post-traumatic stress disorder (PTSD) focused primarily on measuring of small brain structure volume or regional brain volume changes. There were rare reports investigating cortical thickness alterations in recent onset PTSD. Recent advances in computational analysis made it possible to measure cortical(More)
AIM To evaluate the efficacy of reduced cathartic bowel preparation with 2 L polyethylene glycol (PEG)-4000 electrolyte solution and 10 mg bisacodyl enteric-coated tablets for computed tomographic colonography (CTC). METHODS Sixty subjects who gave informed consent were randomly assigned to study group A, study group B or the control group. On the day(More)
The aim of the present study was to clarify whether simulated microgravity-induced post-suspension cardiovascular deconditioning in rats could be prevented by daily short-duration standing (STD). Three groups of rats were used as subjects to perform the experiments. Compared to a control group of male Sprague-Dawley rats (CON), a group of rats with(More)
BACKGROUND It is difficult to assess how different combinations of recently developed anti-G protective equipment will affect +Gz tolerance and central hemodynamics during high G solely by centrifuge experiments. In this paper we report a mathematical model simulating the effects of various combinations on human circulatory response and +Gz tolerance, and(More)
BACKGROUND The push-pull maneuver (PPM) can lead to loss of consciousness in pilots of high-performance aircraft. Modeling of the physical and physiological aspects of this phenomenon should allow improved countermeasures. METHODS A structurally based mechanistic computer model was developed to incorporate dynamic carotid baroreflex responses and detailed(More)
BACKGROUND The push-pull maneuver (PPM) can lead to loss of consciousness in pilots of high-performance aircraft. This paper presents a mathematical model for the simulation of carotid baroreflex function and sympathetic responses during PPM. METHODS The previous model was first modified by incorporating a submodel of the carotid baroreflex and then(More)
