Introduction: Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in human. PorA is a major component of the outer membrane of N. meningitidis and functions as a cationic Porin. This study aimed to clone and determine the expression of PorA as the first step for producing a proper antigen in a vaccine study against N. meningitidis. Methods: An approximately ...
Baculovirus/insect cell expression systems have been in use for several years, often resulting in very high levels of expression of recombinant proteins (1). For expression of mature proteins the preferred vectors, such as pVL941 (2) or p36C (3), utilise the strong polyhedrin promoter and leader sequence. We recently reported the finding that the presence of a 24 bp bacterial sequence immediate...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
Among the biodiversity of soil microorganisms, bacteria have the basic role in soil functions. In order to determine the diversity and abundance of soil bacteria in arid regions, and also to study the effect of agricultural practices on them, a study was conducted in winter wheat fields on Shirvan, Mashhad and Gonabad. In each region, high and low input fields of winter wheat and a natural syst...
meningitis is an inflammation of the membranes that surround the brain and spinal cord, thereby involving the arachnoid, the pia and the cerebrospinal fluid (csf). it is divided into viral and bacterial meningitis. for different reasons the diagnosis of bacterial meningitis is very important. the examination of csf samples may provide information about causative microorganism. the sensivity of ...
Cellular burden limits the applications of bacterial synthetic biology. Experimental approaches for minimisation have recently become available. Tools to identify construct design with low footprint on host include capacity monitors that quantify cellular capacity, high-throughput and cell-free systems prototyping. Orthogonal ribosomes feedback controllers are instead useful seek control resour...
Background: Thrombopoietin is a glycoprotein produced by liver and kidney which is responsible for regulating the platelet production. Thrombopoietin is a key ligand with impact on regulating the self-renewal of Hematopoietic stem cells and the regulation of Megakaryocytes progenitors. Previous studies have indicated that only N-terminal domain of this protein has receptor promoting ability. Th...
