ABSTRACT
Teratomas are benign germ cell tumors that usually found out of their anatomical origin. Teratomas usually are found in sacrococcygeal area, gonads, mediastinum, cervicofacial region and intracranial fossa. Spinal teratomas are rare. In this study we describe a case of conus medullaris teratoma which was diagnosed based on imaging studies. The patient underwent surgery. We did bilateral laminectomy. The mass lesion had an obvious and rigid attachment to the conus medullaris. The wall of the lesion was resected as much as possible, but total resection of the lesion’s wall could not be done due to changes in neural monitoring. Previous related studies are reviewed.
ABSTRACT
Objective: The present study aimed to investigate effectiveness of mindfulness exercises on the executive functions of elementary school students
Methods: To this end, 32 female students of second and third grade were selected by cluster sampling method with regard to inclusion criteria [having average IQ, being right-handed] and exclusion criteria [having physical and mental illness, or psychological and psychiatric interventions] and randomly assigned in experimental [mean +/- SD age; 97.12 +/- 3.48 mo] and control groups [mean +/- SD age; 96.18 +/- 3.33 mo]. Then, the experimental group participated in 8 sessions of mindfulness exercise [each session, 1 h], but control group received no intervention. Before and after intervention, all participants took working memory test, continuous performance test, and Wisconsin card sorting test. Finally, the obtained data were analyzed by ANCOVA with SPSS 21 software
Results: Our findings showed that mindfulness had significant effect on forward and backward memory as well as total score of memory [P<0.01]. Also, findings showed that mindfulness improved perseveration dimension of cognitive flexibility [P<0.05]. Finally, mindfulness could somewhat improve response time of attention [P<0.01]
Conclusion: These findings are consistent with previous research in which the effectiveness of mindfulness on executive functions was approved, though in some dimensions of our variables, the effects were not significant which might be due to the limited sessions of training
ABSTRACT
Objective: Although emotions help us respond compatibly to the problems and opportunities we encounter in life, their deviation can lay the foundation for emotional disorders. Perfectionism is a person's wish to meet ones as well as others' expectations, albeit with better quality than what the situation allows. According to research literature it seems that dimensions of perfectionism can predict the severity of emotional disorders. The purpose of this study was to examine the relationship between perfectionism and symptoms of emotional disorders
Methods: This study was a descriptive, cross sectional, and correlation research. To achieve the research objectives, two questionnaires of inventory of depression and anxiety symptoms [IDAS], and perfectionism inventory were administered to a sample of 385 students studying at Azarbaijan Shahid Madani University
Results: The results demonstrated that there is a strong correlation between perfectionism and severity of the emotional disorder symptoms. Furthermore, the independent variables such as the component of perfectionism can optimally predict the emotional disorders severity [sig=0.001]
Conclusion: Considering the role of perfectionism in the prediction, etiology, and treatment of emotional disorders, in order to enhance the mental health of the society, it is essential to take a practical approach towards such studies
ABSTRACT
The aim of the present study was to examine the sensitivity level of Behavioral Approach System [BAS] and Behavioral Inhibition System [BIS] as probable predisposing factors for substance abuse. To this end, the difference of sensitivity levels of BAS and BIS were assessed in substance abusers, cigarette smokers, and normal individuals. The present causal-comparative study compared the sensitivity levels of approach and inhibition behavioral systems in the following three groups: substance abusers [n=43], cigarette smokers [n=45] and normal individuals [n=55], using BIS/BAS scales. Data were analyzed using X[2] distribution, one way analysis of variance, multivariate analysis of variance, and follow-up tests. The scores of BAS subscale in substance abusers and cigarette smokers were higher than that of normal individuals [p

Inflammation plays a critical role in atherogenesis. The initial step in atherosclerosis is the adhesion of leukocytes to activated endothelial cells mediated by ICAM-1, an inflammatory protein. Several polymorphisms for Intracellular adhesion molecule -1[ICAM-] gene have been described. To determine the possible role of G241R and K469E polymorphisms in development of coronary artery disease and MI. G241R polymorphism was investigated in 303 patients with angiographically documented CAD, including 151 patients with acute or chronic myocardial infarction [MI], and a control group consisting of 141 healthy subjects with normal coronary angiogram. K469E polymorphism was investigated in 309 patients with CHD, including155 patients with MI, and compared with 150 healthy subjects without CHD as the control group. Finally, G241R and K469R polymorphisms were assessed concurrently in 300 patients with CHD including 152 patients with MI and 140 healthy normal subjects without coronary heart disease [CHD]. Although the frequency of GR and RR genotypes were higher in the control group compared to the CHD patients, the difference was not statistically significant [7.09% vs. 5.6% and 1.4% vs. 0%, p=0.27and p=0.24, respectively]. Despite the higher frequency of KK genotype in the CHD group, the difference was not significant [29.1% vs. 24.6%, p=0.62]. KKGG genotype was more frequent in the CHD group, however the difference was not significant [31.1% vs. 27.3%, p=0.66]. No strong relation was found between G241R and K469E polymorphisms and occurrence of CHD and MI in the studied population from Fars province, Iran
