Background and Objectives: To determine the association of hyper-reactivity to environmental allergens and mucosal secretion cytology with the course of disease in patients with chronic rhinosinusitis and nasal polyps (CRSwNP). Methods: A cross sectional study was conducted at Tehran Clinic of Asthma and Allergy in 2016. Adult patients who earned the definite diagnosis of CRSwNP and were free o...
The discovery of a specialized neuronal pathway for itch has markedly improved our understanding of itch processing under physiological conditions. However, the complex interactions of pain and itch are only partly understood. This review focuses on the neurophysiological mechanisms involved in clinical and experimental itch conditions. There is emerging evidence that similar patterns of periph...
We introduce two abstract, causal schemata used during causal learning. (1) Tolerance is when an effect diminishes over time, as an entity is repeatedly exposed to the cause (e.g., a person becoming tolerant to caffeine). (2) Sensitization is when an effect intensifies over time, as an entity is repeatedly exposed to the cause (e.g., an antidepressant becoming more effective through repeated us...
Introduction: Previous studies have shown that the basolateral amygdale (BLA) is rich of CB1 cannabinoid receptors and involved in cannabinoid-induced antinociception. Also, it seems that there are functional interactions between the cannabinoid CB1 and opioid receptors in the process of sensitization to opiates. In the present study, we tried to examine the role of intra-BLA cannabinoid rece...
Introduction: The influence of ascorbic acid on the nicotine-induced conditioned place preference (CPP) and behavioral sensitization was investigated in the present study. Methods: In a pilot study, place conditioning and locomotor activity were investigated after nicotine (0.25, 0.5, 0.75, 1, 1.5 and 2 mg/kg) or ascorbic acid (1, 10, 100 and 1000 mg/kg) administration. Different doses of a...
