The two main arms of the stress system include the autonomic nervous system (ANS) and the hypothalamic-pituitary-adrenal (HPA) axis. These two neural stress systems coordinate the response of many other physiological systems to a stressor, including the immune and cardiovascular systems, bringing the body back to homeostasis. The nervous and immune systems communicate with each other in a bidir...

Exercise ECG (SECG) is one of several noninvasive test procedures routinely used to diagnose coronary disease presence and to estimate prognosis. Unfortunately, like all current noninvasive procedures used for this type of risk stratification, test accuracy is imperfect. A common approach to improve test sensitivity is to implement an additional modality, such as exercise myocardial perfusion i...

h. pylori infection is usually acquired in early childhood. its role in gastrointestinal and extra intestinal complaints and serious consequences in adulthood make it as challenging issues. despite different clinical presentations, in most children, the presence of h. pylori infection does not lead to clinically apparent disease, even when it causes chronic active gastritis. some of most import...

abstractneuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. it is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. neuroimaging modalities include x-ray computed tomography (ct), magnetic resonance imaging (mri), single photon emis...

Analysis of environmental DNA (eDNA) has gained widespread usage for taxonomically based biodiversity assessment. While interest in applying noninvasive eDNA monitoring population genetic assessments grown, its this sphere remains limited. One barrier to uptake is that the effectiveness detection below species level be determined multiple and environments. Here, we test utility emergent technol...

End-systolic left ventricular (LV) meridional wall stress is a quantitative index of true myocardial afterload that can be plotted against LV end-systolic diameter to give an index of contractility independent of loading conditions. We developed a noninvasive method for estimating end-systolic LV meridional wall stress based on M-mode LV echographic end-systolic diameter (LVID) and posterior wa...
