Objective(s): Polyethylenimine (PEI) is one of the most widely used polymers in gene delivery. The aim of this study was to modify PEI by replacing some of its primary amines with Brevinin 2R (BR-2R) peptide in order to increase the efficiency of gene delivery.Materials and Methods: Polyethylenimine was modified by BR-2R peptide by two d...

A 20-year-old male had full manifestation of Coffin-Lowry syndrome and 6 year history of progressively severe drop episodes. His drop episodes were precipitated by unexpected sudden auditory stimuli, and were not associated with electroencephalographical changes. The positron emission tomography disclosed metabolic reduction over bilateral temporal-parietal cortex which could contribute to his ...

Pseudomonas aeruginosa as an opportunistic pathogen is a significant cause of acute and chronic infections in patients with compromised defenses. This bacterium is motile via a single polar flagellum made of polymerized flagellin subunits differentiated into two major serotypes: A and B. flagellin plays an important role as a virulence factor in the adhesion, colonization and invasion of P. aer...

For many years, the dominant conceptual framework for describing non-oriented animal movement patterns has been the correlated random walk (CRW) model in which an individual's trajectory through space is represented by a sequence of distinct, independent randomly oriented 'moves'. It has long been recognized that the transformation of an animal's continuous movement path into a broken line is n...

Context. Oxygen is the third most abundant element in the universe, but its chemistry in the interstellar medium is still not well understood. Aims. In order to critically examine the entire oxygen budget, we attempt here initially to estimate the abundance of atomic oxygen, O, in the only one region, where molecular oxygen, O2, has been detected to date. Methods. We analyse ISOCAM-CVF spectral...

Background and Aims: Newcastle disease virus (NDV) is an avian paramyxovirus (A-PMV 1) and one of the major pathogens in poultries. Vaccination is intended to control the disease, nevertheless this virus is a growing threat to the poultry industry. So, early detection of the virus can prevent the spread of illness and avoid huge economic losses. Towards this goal, in this research, we develop...
