Stress echocardiography (stress echo, SE) is a method in which various stimuli are used to elicit myocardial contractility or provoke cardiac ischemia with simultaneous echocardiographic recording of left ventricular function and valvular flow, if needed(1–7). SE is used for the diagnosis of coronary heart disease and valvular heart defects. The stressors used include physical exercise, pharmacological agents (dobutamine, vasodilators) and pacing stress, most often with the use of

Stress echocardiography (stress echo, SE), with use of both old and new ultrasonographic cardiac function imaging techniques, has nowadays become a widely available, safe and inexpensive diagnostic method. Cardiac stress, such as exercise or an inotropic agent, allows for dynamic assessment of a wide array of ventricles, heart valves and pulmonary circulation functional parameters. The registration of dynamic cardiac response provides completely new insight important from both

Currently, the pathological role of stress in the genesis of neuropsychiatric disorders including depression is being actively studied. An important role has been assigned to emotional stress caused by the cognitive processing of negative stimuli (Yang et al., (2015).
Experimental models of depression can be divided into several groups depending on methodology and type of influencing factor.
The first group includes methods based on the effects of physical stress, which include the

In modern society, more and more people are suffering from some type of stress. Monitoring and timely detecting of stress level will be very valuable for the person to take counter measures. In this paper, we investigate the use of decision analytics methodologies to detect stress. We present a new feature selection method based on the principal component analysis (PCA), compare three feature selection methods, and evaluate five information fusion methods for stress detection.

Depression is the most common form of mental disability in the world. Depressive episodes may be precipitated by severe acute stressful events or by mild chronic stressors. Studies on the mechanisms of depression require both appropriate experimental models (most of them based on the exposure of animals to chronic stressors), and appropriate tests for assessment of depressive states. In this study male Wistar rats were exposed to two different chronic stress paradigms: an eight‑week chronic

Background:Stressor experience is an important topic of research concerning adolescent health and ill-health. For this, valid and reliable measures of adolescent stress are needed. The Adolescent Stress Questionnaire 2 was developed to tap into stressor domains specific for adolescence. Psychometric evaluations in Australian and European samples have indicated adequate psychometric properties. However, the ASQ-2 is quite extensive, which may render its use in large cohort studies, where several

In the course of evolution, living organisms have developed mechanisms allowing them to survive in unfavourable conditions. The adaptation of bacterial cells to conditions abnormal for their growth and survival in a new, changed environment is the result of the cells’ response to stress. In stressful conditions, changes in metabolism occur with a view to protecting a cell. One of the adaptive mechanisms is the stringent response, observed for the first time in Escherichia coli

Oxidative stress refers to an imbalance, which is caused by high levels of reactive oxygen species (ROS) and low levels of antioxidant activity (Preiser 2012). The excessive ROS can damage enzymes, fatty acids, proteins, nucleic acids, and other physiological substances of cells, which leads to structure and function disorders (Dizdaroglu et al. 1992; Wu et al. 2014).

Cortisol, which is the major glucocorticoid produced in the adrenal cortex, has been used as a measure of hypothalamic-pituitary-adrenal axis activity in stress research (Carrasco and Van de Kar, 2003; Miller et al., 2007). Previous studies have revealed that industrial noise at levels > 80 dB has significant effects on salivary cortisol levels in blue collar industrial workers (Fouladi et al., 2012). Muchnik et al. (1998) also found that at the time of the complete arousal

important inputs to the model is the elastic modulus E of the material. The elastic modulus defines the stiffness (resistance to deflection) of the material. Its value is determined from material tests. A material with a high value of E will deflect less than one with a lower value of E. By applying finite element analysis, we can accurately observe the stress distributions in the various layers of the material as shown in Figures 1, 2, 3 and 4.

Captive giant pandas are reported in the literature to perform stereotypic behaviours which are considered to be a behavioural indicator of stress. Although environmental enrichment techniques are commonly used to prevent and/or mitigate performance of stereotypic behaviour in captive giant pandas, evaluation of such techniques is rarely undertaken or reported. This study used behavioural observation methodologies to evaluate the impact of an enclosure rotation as enrichment on the activity

mechanism of the PHB biosynthesis
Poly-3-hydroxybutyrate is a reserve material of bacterial cells and its synthesis takes place under physiological stress conditions. Production and storage of PHB occurs particularly intensively in the shortage of biogenic elements such as: nitrogen, phosphorus, magnesium, and simultaneous excess of the carbon source in the environment [7, 22, 23].
The individual phases of the PHB synthesis are catalysed by specific enzymes (Fig. 2). Their presence determines the

Background:Accumulated evidence indicates that exposure to trauma is associated with the development of cognitive impairments and psychiatric symptoms in children and adolescents.Objective:In this case study of a female adolescent of 17 years, we aimed to evaluate how cortical positron emission tomography (PET) abnormalities relate to psychogenic non-epileptic seizure (PNES) dissociative state, post-traumatic stress disorder (PTSD), attention-deficit/hyperactivity disorder (ADHD), and domestic

There is a need for validated, developmentally sensitive assessment instruments for preschool children. The Diagnostic Infant and Preschool Assessment (DIPA) (1) is a semi-structured caregiver interview that has been developed for this young age group. The interview covers a wide range of child symptomatology and disorders with empirically validated developmental modifications, including posttraumatic stress disorder (PTSD). Our understanding of trauma exposure and trauma reactions

MPH and other neuro-stimulant compounds can cause inflammation, oxidative stress, and mitochondrial dysfunction in brain cells; however the putative mechanism underlying these effects remains unknown (Martins et al., 2006). Interestingly, MPH-induced neurotoxicity seems to be more apparent in certain brain areas, particularly the hippocampus (including CA1, CA2, CA3, and DG subregions) and the amygdala (Morton and Stockton, 2000; Motaghinejad et al., 2017a).

Not only among the youngest patients do the overwhelming objects’ scale, labyrinths of corridors, sterility of rooms, coupled with the dreaded medical technology infrastructure, cause unpleasant associations.

In an animal model of SCI and under conditions of cellular excitotoxicity, VPA functions via HDAC inhibition, which increases cell viability, enhances BDNF expression, prevents the activation of NF-kB, and inhibits ER stress (Scheuing et al., 2014).
