objectives: this present study aims to examine the effectiveness of cognitive-behavioral-based stress management training on anxiety in female ms patients. methods: this study employed a semi-experimental research method with pre-test post-test, control group and random assignment. the statistical population fully consisted of female ms patients referred to the iran ms association in 2014, from...
aim and background: the main purpose of this study was to investigate effectiveness of mindfulness-based stress reduction (mbsr ) on decreasing depression in patients with chronic low back pain. methods and materials: the statistical population included patients with chronic low back pain who appointed the pain clinics in tehran. among whom 23 participants were enrolled with convenience s...
BACKGROUND The computation of arterial wall deformation and stresses under physiologic conditions requires a coupled compliant arterial wall-blood flow interaction model. The in-vivo arterial wall motion is constrained by tethering from the surrounding tissues. This tethering, together with the average in-vivo pressure, results in wall pre-stress. For an accurate simulation of the physiologic c...
The overall performance of sandwiched ultrasonic transducers can be substantially degraded due to defects. Model-based diagnosis can be an attractive technique for monitoring the performance of sandwiched ultrasonic transducers. Using electromechanical models of the transducer, most parameters of the system can be determined based on measurements of electrical input quantities only. This contri...
Mesenchymal niche cells may drive tissue failure and malignant transformation in the hematopoietic system, but the underlying molecular mechanisms and relevance to human disease remain poorly defined. Here, we show that perturbation of mesenchymal cells in a mouse model of the pre-leukemic disorder Shwachman-Diamond syndrome (SDS) induces mitochondrial dysfunction, oxidative stress, and activat...
RATIONALE AMPK (AMP-activated protein kinase) is a heterotrimeric protein that plays an important role in energy homeostasis and cardioprotection. Two isoforms of each subunit are expressed in the heart, but the isoform-specific function of AMPK remains unclear. OBJECTIVE We sought to determine the role of γ2-AMPK in cardiac stress response using bioengineered cell lines and mouse models cont...
BACKGROUND Endoplasmic reticulum (ER) stress-related apoptosis is involved in the pathophysiology of many cardiovascular diseases, and Panax quinquefolium saponin (PQS) is able to inhibit excessive ER stress-related apoptosis of cardiomyocytes following hypoxia/reoxygenation and myocardial infarction. However, the pathway by which PQS inhibits the ER stress-related apoptosis is not well underst...
Oxidative stress markers in Thoroughbred horses after castration surgery under inhalation anesthesia
Oxidative stress has been reported to occur during surgery. It is important to reduce intraoperative oxidative stress to improve the postoperative prognosis. However, there are no reports regarding oxidative stress related to surgery in horses. In the present study, we measured pre and postsurgical diacron-reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP); the oxid...
In this study, we used General Health Questionnaire 30 (GHQ30) and voice to evaluate the stress reduction effect of a stress resilience program, and examined the validity of stress evaluation by voice. We divided the subjects who participated in the program into two groups by the number of training sessions. The results showed a stress-reduction effect only in the group with more training sessi...
