Spatial Learning Paradigm Can Increase Post-Stress Total Time of REM Sleep in Immobilized Rats

Background & Objective: Stress contributes to sleep-wake behavior in all animals. It seems that factors such as learning and memory processes can improve sleep disorders. Therefore, the present study was conducted to determine the effects of stress and learning (spatial memory) on total post-stress rapid-eye-movement (REM), non-rapid-eye-movement (NREM) and waking time in rats. Materials & Met...

Proposed new signal for real-time stress monitoring: Combination of physiological measures

Human stress is a physiological tension that appears when a person responds to mental, emotional, or physical chal-lenges. Detecting human stress and developing methods to manage it, has become an important issue nowadays. Au-tomatic stress detection through physiological signals may be a useful method for solving this problem. In most of the earlier studies, long-term time window was considere...

Mediating Role of Self-efficacy Beliefs in Relationship of Family Emotional Climate and Time Management with Academic Stress among University Students

Background: The minds of students experiencing academic stress fail to quickly analyze the mass of information they are exposed to, resulting in irreparable physical and mental damage. The present study aimed to investigate the mediating role of self-efficacy beliefs in the relationship of family emotional climate and time management with academic stress in university students. Methods: The st...

Retracted: Time course changes of oxidative stress and inflammation in hyperoxia-induced acute lung injury in rats

The effect of oleuropein on the anxiety caused by acute stress via reducing oxidative stress in mice

Introduction: Severe stressful events are associated with the risk of mental disorders such as depression and anxiety. Due to the negative effects of anti-anxiety drugs, researcher’s attention have been focused on finding natural ingredients. The aim of the present study was to investigate the effect of oleuropein on anxiety induced by acute stress in male rats. Materials and Methodes: To induc...

Design and Analysis of Step Stress Accelerated Life Tests for Censored Data}

Life testing often is consuming a very long time for testing. Therefore, the engineers and statisticians are looking for some approaches to reduce the running time. There is a recommended method for reducing the time of failure, such that the stress level of the test units will increase, and then they will fail earlier than normal operating conditions. These approaches are called accelerated li...
