A cross-sectional study is conducted among 212 students, randomly selected from different institutions of the IBN TOFAIL University, located in the city of Kenitra (NW of Morocco). Three neurocognitive tests are used: the short version of the Early Maladaptive Schemas Questionnaire to evaluate the early maladaptive schemas (EMS), the sub-test of the Wechsler to evaluate the working memory among these subjects, and a general questionnaire about socio-economic data, nutritional and mental health status and also, academic performances of each student. The obtained results showed some significant negative correlations between forward memory span and activated schema, and significant negative correlations are registered between backward memory span and activated schema. More, thirty-three percent of students passed the exams of the autumn term against 67% who failed it. Moreover, significant negative correlations are registered between the schemas and the number of Units validated in the autumn term. In addition, fifty-three percent of students had a normal forward memory, 47% had an excellent forward memory and no one had pathological one. However, 63% had a pathological backward memory span, 28% had normal memory and 9% had an excellent backward memory. The EMS appeared in connection with the student’s working memory and the academic performance. Deeper investigations are needed to understand this relationship and also to study other possible factors that could affect this important neurocognitive function.展开更多

Methods: We conducted the study using the Young Schema Questionnaire-Short Form (YSQ-SF) and the Cloninger’s Temperament and Character Inventory (TCI) in 122 university students from different schools. Results and Conclusion: Results demonstrated that there are high level of positive as well as negative correlations between most of TCI items and some of the sub-scales of the YSQ, including vulnerability, social isolation and defectiveness. In consistent with the Halvorsen et al.’s findings, our study demonstrated that harm avoidance had a positive relationship with several EMSs, including emotional deprivation, deficiency, dependence, failure, subjugation and selfsacrifice. More importantly, we obtained the results consistent with theirs regarding the negative correlations between self-directedness and almost all of EMSs, with the exception of the schema of subjugation. We concluded that although some of the personality characteristics contained in the YSQ and the TCI are appeared to be related to each other, we need more studies to support the Young et al.’s suggestion that early maladaptive schemas (EMSs) are likely to reflect underlying characterological factors of personality.展开更多

The Hippo signaling pathway is an evolutionarily conserved pathway implicated in cell proliferation, dedifferentiation, and apoptosis via phosphorylation and inactivation of its downstream effectorsYes-associatedprotein(YAP)/transcriptional co-activator with PDZ-binding motif(TAZ). Recent studies have revealed that the Hippo pathway plays a pivotal role in the pathogenesis and repair of AKI. The Hippo pathway can mediate renal dysfunction through modulation of mitochondrial apoptosis under AKI conditions. Transient activation of YAP/TAZ in the acute phase of AKI may benefit renal recovery and regeneration, whereas persistent activation of YAP/TAZ in severe AKI may lead to maladaptive repair and transition to chronic kidney disease. This review aims to summarize recent findings on the associations between the Hippo pathway and AKI and to identify new therapeutic targets and strategies for AKI.展开更多

The majority of these studies involve proteins which are targets of matrix metalloproteinases. Importantly, these enzyme/substrate interactions can regulate degenerative and regenerative phases of synaptic plasticity, directing axonal and dendritic reorganization after brain insult. The present review first summarizes literature support for the prominent role of matrix metalloproteinases during neuroregeneration, followed by a discussion of data contrasting adaptive and maladaptive neuroplasticity that reveals time-dependent metalloproteinase/substrate regulation of postinjury synaptic recovery. The potential for these enzymes to serve as therapeutic targets for enhanced neuroplasticity after brain injury is illustrated with experiments demonstrating that metalloproteinase inhibitors can alter adaptive and maladaptive outcome. Finally, the complexity of metalloproteinase role in reactive synaptogenesis is revealed in new studies showing how these enzymes interact with immune molecules to mediate cellular response in the local regenerative environment, and are regulated by novel binding partners in the brain extracellular matrix. Together, these different examples show the complexity with which metalloproteinases are integrated into the process of neuroregeneration, and point to a promising new angle for future studies exploring how to facilitate brain plasticity.展开更多

Social deficits represent one of the core symptoms of the diagnosis. The aim was to reveal possible correlations among peripheral levels of oxytocin and testosterone with behavioral and symptom characteristics in patients with ASD. 8 children with ASD were recruited and underwent psychological profiling. Blood oxytocin and testosterone levels were analyzed using ELISA method. Oxytocin levels positively correlated with Adaptation to change category of CARS-2 (P = 0.008, R = 0.848) and Vineland-II maladaptive behavior scores (P = 0.004, R = 0.884). No significant correlations were found among testosterone levels and behavioral parameters. Higher oxytocin levels were connected with more severe adaptive behavior in ASD patients. Increased oxytocin levels in children with more severe phenotype could be a result of compensatory mechanism of impaired oxytocin signaling. Oxytocin seems to employ distinct mechanisms in regulating social behavior in autism and healthy population.展开更多

The patient was a 41-year-old man. He began to complain of photosensitivity at 4 months after head trauma. Ophthalmic evaluation, including visual-evoked potential and conventional brain magnetic resonance imaging, did not reveal a pathologic basis for photosensitivity. Axonal injury in the left optic radiation was detected via diffusion tensor imaging at 36 months after head trauma. The lesion was almost recovered at 76 months. However, photosensitivity continued. Therefore, the photosensitivity was considered to be a result of axonal injury to the left optic radiation, which could be a symptom of maladaptive plasticity that occurs during recovery of axonal injury of the left optic radiation.展开更多

However, the discussions about narcissists as organization members or leaders have recently become a research topic in the organizational sciences. In this scope, the recent research on narcissism indicates that narcissistic leaders can either cause organizational tragedies or contribute to organizational success by their great vision. In addition to narcissism, another popular leadership feature is political skill which has attracted considerable attentions in recent years, and become one of the important topics of management studies. Moreover, political skill has been asserted to be a positive characteristic which is related to develop vision and team insight as well as to increase in members＇ trust and support; whereas narcissism has both harmful and beneficial effects on organizations. In this study, the relationships between the dimensions of narcissism and political skill are examined via the 16-item Narcissistic Personality Inventory （NPI） and the 18-item Political Skill Inventory. Analysis has shown that the authority, which is the adaptive dimension of narcissism, correlates positively with social astuteness and networking ability dimensions of political skill. Accordingly entitlement, which is one of the maladaptive dimensions of narcissism, correlates significantly and negatively with the networking ability, interpersonal influence and apparent sincerity dimensions of political skill. When political skill is considered as a composite score, the findings indicate that the authority dimension of narcissism has a positive effect whereas, the entitlement dimension has a negative effect on political skill. Besides, implications for future studies are discussed展开更多

Rendering explicit the underlying assumptions of this process through a phenomenological analysis constitutes a necessary step toward a version of education extended beyond schools, and as such meant to deepen the self-understanding of the society in case as a whole. A local cultural sanction can be regarded as symptom of a problematic normalization within the wider, global context--at least as a form of moral apathy if not quite what psychiatrists call ＂la belle indifference＂. Within the international context of education, passive resistance through inculcated shyness acquires a peculiar status closely analyzed here. To remain non-judgmental would mean to make concessions to such resistances, to ascribe to taboo--ultimately, to institute a detrimental cult of the them a sacrosanct status and to protect them by means of a unnamable and unspeakable in the cross-cultural dialogue.展开更多

One of them is the handling of stressful events. The aim of the present study was to investigate the coping-strategies used by suicide attempters and comparison groups. 37 patients who had recently made a suicide attempt, 38 suicide attempters at follow up, 20 psychiatric follow up controls, and 19 healthy controls filled in the COPE. We found that suicide attempters at long term follow up and healthy controls used more adaptive problem solving strategies than patients who had recently made a suicide attempt, or psychiatric controls at follow up, who used more maladaptive coping strategies. Our findings suggest that suicide attempters in a twelve year follow up are able to use coping strategies similarly to healthy controls by e.g. approaching the stressor actively. Further examinations of the impact of long term professional care and treatment of suicide attempters on their coping strategies are necessary.展开更多
