I understand your pain but I do not feel it: lower affective empathy in response to others' social pain in narcissism.

Introduction: While the relationship between narcissism and empathy has been well-researched, studies have paid less attention to empathic accuracy, i.e., appreciating the precise strength of another person's emotions, and self-other distinction, in terms of the disparity between affective ratings for self and other in response to emotive stimuli.

Isolation of the Anticoagulant and Procoagulant Fractions of the Venom of Iranian Endemic .

Background: The venom of contains both procoagulant and anticoagulant components that can either promote or block the blood coagulation cascade, and some of these components affect platelet function in different ways.

Objectives: The present study focuses on setting up a procedure for the purification of crude venom and designing appropriate clotting tests in order to characterize the procoagulant and anticoagulant fractions of venom.

Methods: Chromatographic methods, including gel filtration, ion-exchange chromatography, and reverse-phase high-performance liquid chromatography (HPLC), were applied for purifying these fractions.

Objective: This cross-sectional study aimed to study the prevalence rate of psychiatric disorders in children and adolescents in Khuzestan province.

Materials & Methods: A community sample consisting of 1028 (51.6% female) children and adolescents aged 6-18 years was selected using a multistage cluster sampling method.

I didn't want to remember memories of caring, but I can't help it": A qualitative study of the experiences of bereaved Iranian carers with elevated levels of prolonged grief symptoms.

The lived experience of caring for people with cancer and the influence of culture on Iranian carers who have elevated levels of prolonged grief symptoms after the death has received little in-depth attention. Bereaved carers ( = 17) were interviewed. All showed high levels of prolonged grief symptoms.

Culture as an effective frame of reference in clinical decision-making: A comparison of Iranian, American, and Canadian psychotherapists.

The therapeutic communication between psychotherapist and client is highly dependent on their socio-cultural background. The purpose of this study was to examine the effects of culture on decision-making style of psychotherapists in three dimensions of decision-making: expedience vs. realism, individualism vs.

Attachment and joint attention in infants: The role of expectation.

Previous research highlighted the correlation between parent-infant's attachment quality and joint attention skills. However, the underlying mechanisms of this relationship are still unclear. The aim of this study was to assess whether it is by mediating the expectation component in Internal Working Models that the quality of attachment style can affect joint attention.

Decoding and reasoning mental states in major depression and social anxiety disorder.

Background: Major depression (MDD) and social anxiety (SAD) disorders are debilitating psychiatric conditions characterized by disturbed interpersonal relationships. Despite these impairments in social relationships, research has been limited in simultaneously evaluating the dysfunction in MDD or SAD within two aspects of theory of mind (ToM): decoding mental states (i.e.

Cultural differences in conceptual representation of "Privacy": A comparison between Iran and the United States.

Culture consists of shared conceptual representations in an individual's cognition. Thus, there may be cultural differences in the representation of a concept. To assess this possibility, we compared the subjective semantic structure of "privacy" in Iran and the United States.

Effect of Periodontal Treatment on the Crevicular Level of High-mobility Group Box 1 and Soluble Triggering Receptor Expressed on Myeloid Cells 1 in Patients with Chronic Periodontitis.

The present study aimed to compare the levels of high-mobility group box 1(HMGB1) and soluble triggering receptor expressed on myeloid cells (sTREM1) in the gingival crevicular fluid (GCF). This cross-sectional cohort trial investigated two groups of 22 eligible chronic periodontitis and 22 periodontally healthy individuals (student volunteers) both before and after the periodontal treatment.  GCF was collected from the deepest pockets with clinical attachment loss≥3 mm.

Affective and cognitive theory of mind in borderline personality disorder: The role of comorbid depression.

Disturbed interpersonal relationships and misreading of others' intentions are core symptoms of borderline personality disorder (BPD). Despite these impairments, some studies have found an enhanced theory of mind (ToM) in BPD patients. Taking this into consideration, the current study attempts to further understand these discrepancies by separating ToM into two domains: affective and cognitive.

SNAP-25 gene variations and attention-deficit hyperactivity disorder in Iranian population.

Objectives: Attention deficit hyperactivity disorder (ADHD) is a common psychiatric condition of childhood characterized by persistent symptoms of hyperactivity, inattention, and impulsivity. The objective of this study was to investigate the association of synaptosomal-associated protein of 25 kDa (SNAP-25) gene variants with ADHD.

Methods: A case-control study with a total of 150 children with ADHD (mean age 9.

Association analysis of DISC1 gene polymorphisms with Attention-Deficit Hyperactivity Disorder in Iranian population.

Background & Objectives: Attention deficit hyperactivity disorder (ADHD) is a common heritable psychiatric disorder with a worldwide prevalence of 5%. The etiology of ADHD is still incompletely understood, but several studies, consistently indicate the strong role of genetic factors on this disorder. The aim of this study was to determine the effect of three SNPs rs11122319, rs11122330 and rs6675281 in the etiology of ADHD in an Iranian children.

Frequency distribution of gastro esophageal reflux disease in inhalation injury: A historical cohort study.

Background: There is no data on the prevalence and the association of gastro esophageal reflux disease (GERD) with toxic fume inhalation. Therefore, we aimed to evaluate the frequency distribution of GERD symptoms among the individuals with mild respiratory disorder due to the past history of toxic fume exposure to sulfur mustard (SM).

Materials And Methods: In a historical cohort study, subjects were randomly selected from 7000 patients in a database of all those who had a history of previous exposure to a single high dose of SM gas during war.

Serum profiles of matrix metalloproteinases and their tissue inhibitors in long-term pulmonary complication induced by sulfur mustard: Sardasht-Iran Cohort Study (SICS).

Sulfur mustard (SM) is a cytotoxic chemical agent which can cause severe irritation and irreversible damages to body tissues. The effect of SM gas on respiratory tract is one of the main causes of short and long term disabling complications. Matrix metalloproteinases (MMPs) have a critical role in controlling extra cellular matrix remodeling and inflammatory responses in lung tissue and are involved in many various chronic pulmonary diseases.

Prognostic factors in gastric cancer using log-normal censored regression model.

Endoscopic transrostral- transsphenoidal approach to petrous apex cholesterol granuloma: case report.

Cholesterol granuloma (CG) of the petrous apex is an inflammatory reaction to the by-products of eroded marrow cavities secondary to chronic obstruction of air cells within the petrous pyramid. We report a case of cholesterol granuloma in the left petrous bone occurring in a 28-year-old woman with an unusual presentation. The woman presented with a 6-month history of intermittent left hemicranial headache and diplopia.
