In work on Wistar rats with experimental crush syndrome and acute alcohol intoxication shown that alterations of «metabolic profile» are stipulated by the lymphatic system, which emerges as an active component to urgent adaptation in critical situations. It is shown by the expressed infringements of an exchange of electrolytes in plasma. lymph and myocardium at the rats, that can make a part of...

A particle system, as understood in computer science, is a novel technique for modeling robots in their environment. Particle systems have traditionally been used for modeling complex dynamics of fluids and gases. In this paper, as the main contribution, we adapt our earlier work on particle systems, to compute a preliminary stress visualization for a bipedal robot walking on a soft sediment. T...

Biochemical integrity of the brain is vital for normal functioning of the central nervous system (CNS). One of the factors contributing to cerebral biochemical impairment is a chemical process called oxidative stress. Oxidative stress occurs upon excessive free radical production resulting from an insufficiency of the counteracting antioxidant response system. The brain, with its high oxygen co...

Novel PC-based cardiac stress test system is considered in this paper. The system consist of ECG signal acquisition module, which is connected to the PC over USB port, software application dedicated to stress testing, ergotest bicycle and treadmill. First, electronic circuits of signal acquisition module are described, and after, software features are presented.

The links between the psychological and physiological features of cancer risk and progression have been studied through psychoneuroimmunology. The persistent activation of the hypothalamic-pituitary-adrenal (HPA) axis in the chronic stress response and in depression probably impairs the immune response and contributes to the development and progression of some types of cancer. Here, we overview...

Free radicals and other active derivatives of oxygen are inevitable by-products of biological redox reactions. Reactive oxygen species inactivate enzymes and damage important cellular components. The increased production of toxic oxygen derivatives is considered to be a universal or common feature of stress conditions. Plant and other organisms have evolved a wide range of mechanisms to contend...

BACKGROUND A substantial number of individuals are at risk for the development of motion sickness induced nausea and vomiting (N&V) during road, air or sea travel. Motion sickness can be extremely stressful but the neurobiologic mechanisms leading to motion sickness are not clear. The endocannabinoid system (ECS) represents an important neuromodulator of stress and N&V. Inhibitory effects of th...

An increasing number of people report concerns about the amount of stress in their life. At the same time obesity is an escalating health problem worldwide. Evidence is accumulating rapidly that stress related chronic stimulation of the hypothalamic-pituitary-adrenal (HPA) axis and resulting excess glucocorticoid exposure may play a potential role in the development of visceral obesity. Since a...
