Abstract: The background for the present study is that facial width-to-height ratio (fWHR) is suggested to function as an evolutionary cue for threatening behavior such as perceived aggression. With a novel approach, in this pilot study, we explored whether fWHR can be detected in observers’ brain responses measured by event-related potentials (ERP), specifically, the Late Positive Potential (LPP) component (400-3000ms after stimuli onset). The hypothesis was that faces with a high fWHR would elicit a larger LPP amplitude than faces with a low fWHR. The results showed that faces with high fWHRs were indeed perceived as more aggressive and elicited significantly greater LPP amplitudes. The conclusion lends initial support to fWHR serving as a facial cue with evolutionary relevance. We caution that future full-length studies need to take the current small-scale study’s limitations into consideration.

Abstract: The current study aims at introducing the relation between the impulsive buying behavior and emotional balance among the students of the Accounting Department in Petra University and Al-Imam Mohammad Ibn Saud Islamic University according to Nationality, Gender and Economic Level, through a sample consisting of (438) persons; (192) from the Accounting Department in Petra University and (246) from the Accounting Department at Al-Imam Mohammad Ibn Saud Islamic University. In order to achieve study objectives, researcher used: the impulsive buying behavior scale developed by Verplanken and Herabadi and translated by Al-Far, in addition to the emotional balance scale prepared by Dicks and translated by Al-Asmari. Study indicated negative correlation of statistical denotation between the impulsive buying behavior and the emotional balance among the students of the Accounting Department; while suggesting no differences of statistical denotation in the level of buying behavior among students depending on the variables of gender or economic level. Outcomes also concluded having differences of statistical indication in the level of emotional balance depending on nationality for the students of the Accounting Department at Al-Imam Mohammad Ibn Saud Islamic University, while not having differences of statistical denotation in the level of emotional balance in all its dimensions among students depending on the variable of gender. Study also indicated differences in the level of emotional balance among students depending on the variable of economic level between those of high economic level and those of low economic level for the benefit of those of high economic level.

Abstract: Systemic lupus erythematosus (SLE) is a diffuse connective tissue disease that is characterized by autoimmune-mediated inflammation. Antiphospholipid syndrome (APS) is a non-inflammatory autoimmune disease. A 55-year-old female patient was admitted to the hospital due to ‘sudden speech insufficiency and aggravation of 5 h’. The patient developed sudden dizziness, facial numbness, and slurred speech and was transported to the emergency department in a local hospital, and was diagnosed ‘cerebral infarction’ after a CT examination. According to the medical records, the patient developed SLE at the age of 25. CT showed low density lesions of the left pons and occipital lobe; emergent MRI showed bilateral infarction in the cerebellum and brainstem, and magnetic resonance angiography (MRA) showed upper basilar artery occlusion. Ischemic stroke was diagnosed and NIHSS scored 30. The occluded artery was successfully recanalized with endovascular mechanical thrombectomy. Modified thrombolysis in cerebral infarction (mTICI) blood flow perfusion grade was grade 3. The case is the first one in the literature that acute ischemic stroke related to SLE vasculitis and antiphospholipid syndrome was treated successfully with endovascular mechanical thrombectomy.
