Background: Hypoxia is a potential danger for aviation affairs and the lack of attention to it causes both human and financial costs. One of the main effects of hypoxia is reduction in mental efficiency. Therefore, the purpose of this study was to investigate the effects of hypoxia on hypoxic psychological aspects (selective attention and reaction time) among pilots as well as changes in heart rate and blood oxygen levels in the flight simulator of an altitude chamber.
Materials and methods: Totally, 53 pilots referred to the altitude chamber at the air physiology center of IRAF were randomly entered the study within 10 months. Initially, the study protocol was described to them. A percentage of arterial oxygen saturation and heart rate and Stroop computer task under normal condition (class) were recorded. Then, in the hypoxic conditions (height 25000 feet) the same items were checked, recorded, and finally analyzed statistically.
Results: The results of this study showed that hypoxia increases the reaction time and heart rate in the pilots. Also, it reduced pilots' selective attention and blood oxygen levels. All of the mentioned items were statistically significant.
Conclusion: Hypoxia can prolong the response time in the pilots and also disturbs their selective attention and increases the risk of accidents. The importance of this issue in fighter aircraft, which is controlled by one or two pilots, can be much more than in a cargo aircraft. Therefore, hypoxia training in the altitude chamber and attention to its psychological aspects can play an important role in correct and on time recognition of the hypoxia and safety of flights.

Background: Anxiety has been identified as the most common mental health disorder and 30% of psychological disorders in societies are due to early-life stress. The aim of this study was to investigate the effect of mandatory exercise on anxiety and bowel oxidative stress in male rats following the maternal separation stress
Materials and methods: In this experimental study, the maternal separation stress on baby rats was applied, so that, babies were separated from their mother during postnatal day (PND) 2 to 14, for 180 minutes a day. At PND 28, rats were randomly divided into five groups including control group, maternal separation stress group, mandatory treadmill exercise, maternal separation with treadmill, and maternal separation with the intake of fluoxetine. At PND 60, after finishing the program, in addition to behavioral tests, biochemical and tissue biopsy, for measuring the oxidative stress biomarkers (ROS level), were applied.
Results: Our investigation revealed that only the intake of fluoxetine during adolescence can significantly make change on the anxiety-like behaviors, ROS level, and the level of mitochondrial glutathione; however, the observed difference among the other groups was not significant.
Conclusion: This study suggested that maternal separation stress was able to appear anxiety-like behaviors. In addition, a significantly change on the bowel oxidative stress was observed. It seems the effect of exercise on stress can be affected by intensity and duration of exercise, the rest time after exercise, and also the stress level before the exercise.

Background: Bipolar and major depressive disorders are the most common mood disorders in the world. Theoretical models have emphasized on the importance of the of impaired cognitive estimation role in these disorders. The aim of this study was to evaluate the effectiveness of acceptance and commitment therapy (ACT) in cognitive estimation of patients with bipolar I disorder and major depressive disorder.
Materials and methods: In the form of a quasi-experimental design, 12 patients with bipolar I disorder and 12 patients with major depressive disorder were selected via a convenience sampling method. Then, they received a treatment based on ACT for eight sessions of 90 minutes. All patients were assessed three times (pre, mid, post ACT) by the impulsivity questionnaire. Data were analyzed by the mixed analysis of variance.
Results: The results indicated that the ACT was effective in improving the cognitive estimation and the components such as size, weight, quantity, and time in both groups of patients (p<0.001).
Conclusion: The ACT with increasing awareness, acceptance, psychological flexibility, and decreasing cognitive fusion improves the cognitive estimation of patients with bipolar disorder and major depressive disorder. Therefore, a planning and education based on this treatment can empower the patients and their families.

Background: Many researchers indicated the relation of suicide with mood disorders. The aim of this study was to compare profile and personality traits of the students with and without suicidal ideation.
Materials and methods: In a causal-comparative study, based on Morgan table, 396 undergraduate students (single= 289 and married= 107), were selected via a multi-stage cluster sampling. All the students completed the Beck Scale for Suicide Ideation, the short form MMPI, and NEO FF-I. Data was analyzed using MANOVA by SPSS software.
Results: The results showed that students without suicidal ideation in comparison with those with suicidal ideation, are more extroversion and liar, and also the K factor is higher among them (p<0.001). Moreover, a wide range of factors such as social-mental deviations, hypochondria, paranoia, hysteria, hypomania, mental weakness, depression, and schizophrenia had significantly (p<0.001) higher scores among the students with suicidal thoughts.
Conclusion: The profile and personality traits were different among students with and without suicidal ideation. This can be important in the prediction and investigation of suicidal ideation on the basis of personality variables.
