عاملهای شناختی، شخصیتی و موقعیتی متعددی یافت شده است که می توانند با پرخاشگری ارتباط داشته باشند. فهم چگونگی ارتباط درونی این عاملها برای پیش بینی، سنجش، و درمان پرخاشگری زندانیانی که سابقه رفتارهای پرخاشگرانه را دارند، بسیار اساسی است. پژوهشهای قبلی نقش بالقوه ای را برای توانایی حل مساله اجتماعی بعنوان یک میانجیگر بین تکانشگری و پرخاشگری پیشنهاد کرده اند.

The platelet integrin, α IIb β $ (GPIIb-IIIa), and the tetraspanin, CD9, are integral membrane proteins that are abundant in platelet membranes. We have identified several proteins, including CD9, which were co-precipitated by anti-α IIb β $ antibody from untreated, resting platelets that were solubilized with the poly(oxyethylene) non-ionic detergent, Brij-35. Immunoblot and quantitative immun...

In this study, using biodegradable polymers, nanofiberouse scaffolds were fabricated from the layer-by-layer electrospinning method, including two layer that poly (ε-caprolactone), polyvinylpyrrolidone deposited at first layer and poly (ε-caprolactone), polyvinyl alcohol , β-tricalcium phosphate at latter. After prepration of scaffolds, scanning electron microscopy (SEM), swelling, porosity, me...

We demonstrate a novel approach to control β-phase content generated in poly(9,9-dioctylfluorene) (PFO) films. A very small amount of paraffin oil was used as the additive to the PFO solution in toluene. The β-phase fraction in the spin-coated PFO films can be modified from 0% to 20% simply by changing the volume percentage of paraffin oil in the mixed solution. Organic light emitting diodes (O...

Electrospun scaffolds of neat poly-ε-caprolactone (PCL), poly-ε-caprolactone/βcyclodextrin inclusion complex (PCL/β-CD) and poly-ε-caprolactone amino derivative inclusion complex (PCL/β-CD-NH2) were prepared by the electrospinning technique. The obtained mats were analyzed by a theoretical model using the Hartree–Fock method with an STO-3G basis set, and characterized by X-ray diffraction (XRD)...

Aromatic polyketides make up a large class of natural products with diverse bioactivity. During biosynthesis, linear poly-β-ketone intermediates are regiospecifically cyclized, yielding molecules with defined cyclization patterns that are crucial for polyketide bioactivity. The aromatase/cyclases (ARO/CYCs) are responsible for regiospecific cyclization of bacterial polyketides. The two most com...

BACKGROUND Fungi may be involved in asthma and chronic rhinosinusitis (CRS). Peripheral blood mononuclear cells from CRS patients produce interleukin (IL)-5, IL-13 and interferon (IFN)-γ in the presence of Alternaria. In addition, Alternaria produces potent Th2-like adjuvant effects in the airway. Therefore, we hypothesized that Alternaria may inhibit Th1-type defense mechanisms against virus i...

Retinoic acid-inducible gene I- (RIG-I-) like receptors (RLRs) have recently been identified as cytoplasmic sensors for viral RNA. RIG-I, a member of RLRs family, plays an important role in innate immunity. Although previous investigations have proved that RIG-I is absent in chickens, it remains largely unknown whether the chicken can respond to RIG-I ligand. In this study, the eukaryotic expre...
