β-Adrenergic Responsiveness in the Type 2 Diabetic Heart: Effects on Cardiac Reserve
LEFT VENTRICLE CARDIAC OUTPUT NERVOUS REGULATION
2018/4/24
Type 2 diabetes (T2D) is associated with reduced cardiac reserve and aerobic capacity. Altered myocardial autonomic nervous regulation has been demonstrated in humans with diabetes (indirectly) and an...
Complete Reversion of Cardiac Functional Adaptation Induced by Exercise Training
PHYSIOLOGICAL HYPERTROPHY DETRAINING PRESSURE–VOLUME ANALYSIS FUNCTIONAL REVERSIBILITY
2018/4/24
Purpose Long-term exercise training is associated with characteristic cardiac adaptation, termed athlete's heart. Our research group previously characterized in vivo left ventricular (LV) function of ...
High-Intensity Interval Training Increases Cardiac Output and V˙O2max
INTERVAL EXERCISE MAXIMAL OXYGEN UPTAKE STROKE VOLUME THORACIC IMPEDANCE FICK EQUATION CYCLE ERGOMETRY
2018/4/24
Increases in maximal oxygen uptake (V˙O2max) frequently occur with high-intensity interval training (HIIT), yet the specific adaptation explaining this result remains elusive.
Purpose This study exam...
Chronic administration of pharmacologic doses of vitamin E improves the cardiac autonomic nervous system in patients with type 2 diabetes
Vitamin E heart rate variability catecholamines
2016/6/13
Type 2 diabetes is associated with elevated oxidative
stress and declines in antioxidant defense. The disease is
also characterized by an imbalance in the ratio of cardiac sympathetic
to parasympat...
Elevated plasma fatty acid concentrations prolong cardiac repolarization in healthy subjects
Fatty acids Q-T interval Q-Tc dispersion
2016/6/12
High fatty acid concentrations have been shown to
stimulate sympathetic nervous system activity, which may modify
ventricular repolarization and thus the Q-T interval on electrocardiogram
recording...
Cardiac Kinetophagy Coincides with Activation of Anabolic Signaling
EXERCISE AUTOPHAGY KINETOPHAGY
2017/4/13
Purpose: Growing evidence has shown that endurance exercise is a strong inducer of autophagy in various tissues. Thus, we define here endurance exercise-induced autophagy as “kinetophagy” derived from...
Neurovascular Control and Cardiac Structure in Amateur Runners with Hypertension
BAROREFLEX SENSITIVITY ARTERIAL STIFFNESS SYMPATHETIC NERVOUS SYSTEM
2017/4/13
Purpose: The neurovascular mechanisms underlying hypertension are minimized by exercise training. However, it is not known whether previously trained individuals with hypertension would have deleterio...
Acute Physiological Responses to Short- and Long-Stage High-Intensity Interval Exercise in Cardiac Rehabilitation:A Pilot Study
intermittent exercise exercise prescription acute effects health-related markers heart disease patients
2016/3/11
Despite described benefits of aerobic high-intensity interval exercise (HIIE), the acute responses during different HIIE modes and associated health risks have only been sparsely discovered in heart d...
Thermal dependence of cardiac SR Ca2t-ATPase from fish and mammals
SERCA2 Cardiac myocytes Cold adaptation Endothermic fish Ventricles
2015/11/16
The thermal sensitivity of metabolic performance in vertebrates requires a better understanding of the temperature sensitivity of cardiac function. The cardiac sarco/endoplasmic reticulum Ca2t-ATPase ...
Crude Oil Impairs Cardiac Excitation-Contraction Coupling in Fish
Crude Oil Cardiac Excitation Contraction Coupling Fish
2015/11/16
Crude oil is known to disrupt cardiac function in fish embryos. Large oil spills, such as the Deepwater Horizon (DWH) disaster that occurred in 2010 in the Gulf of Mexico, could severely affect fish a...
Cardiac function in an endothermic fish:cellular mechanisms for overcoming acute thermal challenges during diving
Thunnus orientalis calcium transient action potential L-type Ca current heart rate adrenaline
2015/11/16
Understanding the physiology of vertebrate thermal tolerance is critical for predicting how animals respond toclimate change. Pacific bluefin tuna experience a wide range of ambient sea temperatures a...
Primary Cardiac Angiosarcoma in a Middle Aged Woman
Cardiac Tumors Sarcoma Angiosarcoma Echocardiography
2015/11/6
Introduction: Primary cardiac angiosarcoma is the most common primary sarcoma in adults between the 3rd and 4th decades of life. Nearly 90% of angiosarcomas occur in the right atrium, which is respons...
Behavioral Change Challenges in the Context of Center-Based Cardiac Rehabilitation:A Qualitative Study
Behavior Rehabilitation Analysis
2015/11/6
Background: Cardiovascular disease is chronic and often a sign of long-standing unhealthy lifestyle habits. Patients need support to reach lifestyle changes, well-being, join in social and vocational ...
In cycling as in other types of strenuous exercise, there
exists a risk of sudden death. It is important both to understand its causes and to see if the behavior of certain
biomarkers might highli...
