The IPAC-NC field campaign: a pollution and oxidization pool in the lower atmosphere over Huabei, China
In the past decades, regional air pollution characterized by photochemical smog and grey haze-fog has become a severe environmental problem in China. To investigate this, a field measurement campaign was performed in the Huabei region, located between 32–42 N latitude in eastern China, during the period 2 April–16 May 2006 as part of the project “Influence of Pollution on Aerosols and Cloud Mic...
متن کاملبررسی ایمنی زائی نانوژل کایتوسان واجد پروتئین نوترکیب IpaC از شیگلا در خوکچه هندی
Background and purpose: Shigella species cause shigellosis in humans. Considering the high frequency of illness and antibiotic resistance, development of an effective immunogen against bacteria is a major goal. Invasion Plasmid Antigen such as IpaD and IpaC are the major bacterial virulence agents of Shigella. Encapsulation of antigens in particular carriers such as chitosanic nanogels, n...
متن کاملImmunogenicity of a New Recombinant IpaC from Shigella dysenteriae Type I in Guinea Pig as a Vaccine Candidate
Background: Recombinant vaccine technology is one of the most developed means in controlling infectious diseases. However, an effective vaccine against Shigella is still missing. Objective: To evaluate recombinant IpaC protein of Shigella as a vaccine candidate. Methods: In this study we cloned IpaC gene into an expression vector in prokaryotic system. The protein expression was evaluated by SD...
متن کاملProbiotic Bifidobacterium Lactis Bacteria Inhibit the Invasion Phenotype of Shigella Dysenteriae Induced By Invasion Plasmid Antigen C
Background and Aims: Shigellosis is an acute gastroenteritis and Invasion plasmid antigen C (IpaC) is the first effector protein for Shigella invasion of intestinal cells. Among lactic acid bacteria, Bifidobacterium lactis (B. lactis) has received increasing attention for protection of a potential host against gastrointestinal infections. The aim of this study was to investigate the inhibitory ...
متن کاملStructural characterization of the N terminus of IpaC from Shigella flexneri.
The primary effector for Shigella invasion of epithelial cells is IpaC, which is secreted via a type III secretion system. We recently reported that the IpaC N terminus is required for type III secretion and possibly other functions. In this study, mutagenesis was used to identify an N-terminal secretion signal and to determine the functional importance of the rest of the IpaC N terminus. The 1...
