Polyunsaturated fatty acid consumption, plasma cholesterol concentration and neuroendocrine response to mental and physical task load

This study was designed to investigate the relation between fatty acid consumption, total plama cholesterol and neuroendocrine response to exposure to stress, factors thought to play a role in the development of coronary heart disease. For this purpose 32 apparently healthy male volunteers were classified on the basis of their plasma cholesterol...

Type A behaviour, borderline hyperventilation and psychological, psychosomatic and neuroendocrine responses to mental task load

Psychological, psychosomatic and neuroendocrine (in blood) responses to mental task load were investigated in relation to type A behaviour and borderline hyperventilation. For this purpose 32 apparently healthy, male volunteers were classified on the basis of their scores on the Jenkins Activity Survey (JAS) and on a questionnaire assessing...

Urinary excretion of 3-methylhistidine and creatinine by healthy Dutch children during day and night. The influence of age and sex

The urinary excretion of 3-methylhistidine and creatinine and the urinary 3-methylhistidine to creatinine excretion ratio during day and night were investigated in a group of 103 healthy, normally fed Dutch children (52 boys and 51 girls) aged 2-17 years. The 3-methylhistidine to creatinine ratio of the night urine appeared to be significantly...

Vitamin B6 status of women suffering from premenstrual syndrome

The vitamin B6 status of women suffering from premenstrual symptoms (PMS, n = 19) and a group of matched controls (n = 19) has been investigated. The women volunteering in the study were selected on strictly defined criteria. Several biochemical parameters of the metabolism of vitamin B6 and tryptophan were studied in blood and urine samples...

Effect of work load on free and sulfate-conjugated plasma catecholamines, prolactin, and cortisol

The effects of maximal performance capacity and different work load intensities on the response of free and sulfate-conjugated plasma catecholamines, prolactin (PRL), and cortisol were studied in six healthy male volunteers. In a first experiment, the volunteers had to perform a step-wise incremental bicycle ergometer test to determine the onset...
