thioredoxins (trxs) are small heat-stable proteins that are involved in the cell redox regulation and are present in all organisms from prokaryotes to higher eukaryotes. in higher plants, trxs can be classified into six different groups namely: the chloroplastic trxs f, m, x, and y, the mitochondrial trx o and the trxs h. the trxs h are represented by a small multigenic family that participate ...
objective: toxoplasmosis, caused by an intracellular protozoan parasite, and the toxoplasma gondii, is widespread throughout the world. in recent years, significant progress has been made in the identification of vaccine candidates which could induce a protective response. gra7, an excretory 29 kda toxoplasma gondii a dense granular antigen released by infected host cells. in tachyzoite-infect...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
Background and Objective: The glycoprotein hormone secreted from anterior pituitary gland are heterodimeric, non- covalently consisting of a common α subunit and a hormone-specific β subunit. Due to the lack of adequate access to hormones and the possibility of contamination, this study attempted to clone two subunits of LH hormone by using IRES sequence in eukaryotic expression vector pEGFP-NI...
Background: Rabies is an acute encephalitis that causes more than 60,000 deaths worldwide. The only way to save individuals bitten by a rabies-infected animal is the timely use of effective vaccines. Treatment with new generation vaccines is expensive. Therefore, there is a global movement towards the production of less expensive vaccines which retain and improve upon the quality and effectiven...
objective: e1a oncoprotein of adenovirus type 5 is a regulatory factor which controls transcription of other adenovirus genes. this protein promotes both viral genom replication and host cell transformation by altering the function of certain important cellular proteins such as p21 and rb. the aim of the present study was to constantly reduce the expression of e1a gene in hek 293 cell line by r...
Leishmanolysin is a worldwide disease that is caused by different species of the genus Leishmania. Leishmanolysin, One of the genes expressed by Leishmania, appears to be an ideal candidate for genetic vaccination. In this study, a full length sequence, which encodes Leishmanolysin functionally critical regions (amino acids 100-579), was cloned from a Leishmania strain endemic to Iran. Analysis...
Introduction: Mycoplasmas are one of the most serious contaminants of cellular cultures and their biological productions. Mycoplasma diagnosis is conducted on the basis of culture and molecular methods. These methods are different from each other in terms of accuracy, reliability, and sensitivity. This study aimed to trace the mycoplasma contaminations in culture samples using 16S rRNA specific...
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...
A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon.
