Abstract. The impact of sodium intake on cardiovascular health has long been a subject of controversial debates. On the one hand, the World Health Organization (WHO) and the American Heart Association (AHA) have ...
Abstract. Inconsistent findings have been reported regarding the effects of vitamin D on blood pressure in patients with type 2 diabetes (T2D). This study aimed to evaluate the subject through a meta-analysis. A ...
Abstract. The cardiovascular health benefits of shea butter, an edible off-white or ivory-colored fat native to West Africans has never been investigated. This is in spite of anecdotal evidence, which suggests that shea butter may have medicinal ...
Abstract.Objective: To assess whether zinc deficiency is associated with prehypertension (preHTN) in apparently healthy subjects. Design: Apparently healthy women and men, aged 20 to 60 years were enrolled into a case-control study. Individuals with and ...
Abstract.Background: The association between dietary patterns and cardiorespiratory fitness (CRF) is not well established. Objective: We sought to investigate association between a posteriori dietary pattern and CRF in middle-aged adults. Design: Adults ...
Abstract.Objective: The genetic variants near the melanocortin-4 receptor gene (MC4R), a key protein regulating energy balance and adiposity, have been related to obesity and cardiovascular risk factors. However, qualitative and quantitative aspects of ...
Abstract. Guar gum has been used in the management of hypercholesterolemia, constipation, weight loss, type 2 diabetes mellitus and hypertension. Our aim was to verify the hypothesis that Guar gum can be used as an alternative to pharmacological agents ...
Abstract:Background: Numerous studies have revealed the protective role of dietary antioxidants against hypertension and diabetes. In the current systematic review and meta-analysis, we evaluated the possible role of dietary total antioxidant capacity (...
Abstract: High dietary sodium and low potassium intake is associated with high blood pressure (BP). The current study aimed to determine if the sodium-to-potassium ratio is more strongly associated with low (130–139/80–89 mm Hg) and high (≥140/90 mm Hg) ...
Abstract. Background: Increased central pulse wave velocity is a major risk factor for cardiovascular disease. The favorable influence of exercise on arterial stiffness (AS) and blood pressure (BP) has been reported exclusively at rest. The present study ...
Abstract.Background: Cardiovascular diseases are the leading cause of death in Germany. The knowledge of causal risk factors and their distribution is of utmost importance to design screening programs. Probands and ...
Telemedicine comprises different concepts aiming to close a spatial distance between practitioner, medical staff and patient. Its functionality can include mere data transmission but extend as well to triggering alarms or enable consultation and therapy ...
Acute Effects on TH4 Thoracic Spine Mobilisation Techniques on the Sympathetic Nervous System – a Cross-Over Feasibility StudyAbstract. Up to date, empiric evidence about effects of thoracic spine mobilisation (TH4) on the ...
Effects of Music on the Cardiovascular System: What is Verified, What Not, What’s New?It is well known that music not only may improve quality of life (QoL) but also have different effects on heart rate (HR) and ...
Abstract For many years psychophysiologists have been interested in stimulus related changes in heart rate and blood pressure. To represent these evoked heart rate and blood pressure patterns, heart rate and blood pressure data have to be transformed into ...
Abstract Effects of maintaining an alert state on event-related brain potentials (ERPs) and evoked cardiovascular responses were examined in an auditory detection task. Subjects were instructed to detect a possible difference in frequency between two ...
Objective: To study gender differences of cardiovascular responses due to painful stimuli during sphygmomanometry. Methods: We studied 80 subjects (40 women, 40 men). Blood pressure (BP) was determined continuously and noninvasively using a Finapres ...
Abstract Peripheral blood pressure measurement (Finapres technique) is a promising development in activation research. This paper tests and compares the temporal stability and covariation of peripheral and brachial blood pressure responses. Forty healthy ...
Abstract: Existing evidence suggests that baroreceptor stimulation may impair sensorimotor functioning. The purpose of this study was to determine whether the adverse effect of baroreceptor stimulation on sensorimotor functioning is more pronounced among ...
This paper reports three studies on the application of ambulatory monitoring in air traffic control (ATC). The aim of the first study was to explore a set of psychophysiological measures with respect to ATC workload sensitivity and feasibility at the ...
There is broad evidence for a functional interaction between the cardiovascular and pain regulatory systems. One result of this interaction is the reduced sensitivity to acute pain in individuals with elevated blood pressure, which has been established in ...
The present study explored modulations in cerebral blood flow and systemic hemodynamics during the execution of a mental calculation task in 41 healthy subjects. Time course and lateralization of blood flow velocities in the medial cerebral arteries of ...
Recent studies have revealed evidence for increased pain sensitivity in individuals with chronically low blood pressure. The present trial explored whether pain sensitivity can be reduced by pharmacological elevation of blood pressure. Effects of the ...
Objectives: Previous research suggests that mechanisms related to afferent and efferent components of the baroreflex are associated with blood pressure level and mood, and that mood as a component of subjective well-being may be mediated by changes in ...
Abstract. Chronic low blood pressure (hypotension) is accompanied by symptoms such as fatigue, reduced drive, faintness, dizziness, cold limbs, and concentration difficulties. The study explored the involvement of aberrances in autonomic cardiovascular ...
Abstract. Tasks such as the Trier Social Stress Test, narrative recall, and some cognitive challenges require participants to speak in order to measure acute physiological responses to induced stress. Typically, the physiological measures during the ...
Abstract. Narrative recall, or describing an event from one’s past, is a common method to study anger in the laboratory. However, most research using this method has not included a neutral speaking control, and therefore the physiological response ...
Abstract. This study examined whether the relationship between subjective and physiological outcomes of stress, and the responsivity to stressors, are affected by whether participants can see a visual display of their physiological output. ...
Rapid technical developments have greatly facilitated noninvasive 24-hour recording of physiological signals at relatively low costs, including blood pressure, activity of the autonomic nervous system, respiratory behavior, and activity of the ...
