in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
background: angiogenesis is an important process in various physiologic and pathologic states. the most significant stimulator of angiogenesis is vascular endothelial growth factor (vegf). in contrast, vasohibin1 acts as an angiogenesis inhibitor which specifically inhibits new vessels formation. the aim of the present study was cloning and expression of vasohibin1 gene in e. coli as well as pu...
Clostridium perfringens beta toxin is only produced by types B and C and plays an important role in many human and animal diseases, causing fatal conditions that originate in the intestines. We compared the expression of C. perfringens type B vaccine strain recombinant beta toxin gene in the Escherichia coli strains RosettaTM(DE3) and BL21(DE3). The beta toxin gene was extracted from pJETβ and ...
Human Interferon β (INF-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. In this study an expression vector was designed and constructed for expression of human INF-β-1b either in shake flasks and bench top bioreactor. The designed vector was constructed based upon pET-25b(+) with T7 promoter. Recombinant human beta interferon ...
Background: The purpose of this study was to clone, express, and purify a novel multidomain fusion protein of Micobacterium tuberculosis (Mtb) in a prokaryotic system. Methods: An hspX/esxS gene construct was synthesized and ligated into a pGH plasmid, E. coli TOP10 cells were transformed, and the vector was purified. The vector containing the construct and pET-21b (+) plasmid were digested ...
background and objectives: during past decades hansenula polymorpha has attracted global attention for the expression of recombinant proteins due to its high growth rate, minimal nutritional porequirements and use of methanol as a low cost inducer. materials and methods: the corresponding nucleotide sequences for the expression of heterologous genes in hansenula poylmorpha were extracted and as...
The gene encoding the human basic fibroblast growth factor (hbFGF) has been already chemically-synthesized and cloned in pET-3a expression vector (Pasteur Institute of Iran). In the present study, we compared the level of expression of this synthetic hbFGF and its related cDNA in Escherichia coli. The pBR322-cDNA of hbFGF supplied by Dr. Seno (from Molecular Biology Dept, Okaido prefectural uni...
background human preimplantation embryonic cells share many similarities with cancer cells such as ability to self-renew, unlimited proliferation and maintenance of the undifferentiated state. embryo-cancer sequence a (ecsa), also known as developmental pluripotency associated-2 (dppa2), is a cancer testis antigen (cta) with unclear biological function yet. objective: ctas are expressed normall...
Objective(s) Lipocalin 2 (Lcn2) is a 25-kDa glycoprotein that has initially been extracted from neutrophil granules. Expression of Lcn2 is induced under various pathophysiological conditions. It is also known as an early marker of kidney and heart injury. High-level expression of recombinant Lcn2 neutrophil gelatinase-associated(NGAL) in insect cells was the aim of this study. Materials and M...
Background and Aim: Angiogenesis is one of important biological processes any disruption in which leads to disease. The main signaling factor in this process is VEGF which acts through its receptors. The present study was done in order to inhibit the expression of receptor type1of this factor (VEGFR-1) using specific siRNA in the culture medium to use its inhibitory effect on neovascularization...
