The (-)-hyoscyamine, atropine and scopolamine (hyoscine) are three valuable tropane alkaloids while scopolamine is the most important member of this group for the pharmaceutical industry due to its higher demand compared to hyoscyamine and atropine. Scopolamine is an anticholinergic reagent with several therapeutic applications. In the current study, the hairy roots culture of Daturametel was used as an advantageous method for production of scopolamine. The hairy roots are formed by Agrobacterium rhizogenes and have genetic stability, high growth rate and lateral branching...

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of Johne's disease in ruminants and there has been a shift in the public health approach to MAP and human diseases like Crohn's disease. The prevention of infection by MAP in ruminants is thought to deter the high impact of economic losses in the level of dairy industry and possible spreading of this pathogen in dairy products. The present study was done to investigate the construction and expression of the soluble form of a novel fusion protein, consisting of Heparin-binding hemagglutinin (HBHA) and high antigenic region of Fibronectin Attachment Protein-P (FAP-P), in order to introduce as a Th1 inducer subunit vaccine against MAP...

Genetic structure of an endemic tooth-carp fish, Aphanius farsicus from four different water bodies in the Maharlu Lake basin was investigated by applying five microsatellite markers. All of the five examined microsatellite loci showed polymor-phism pattern. A total of four alleles were detected at five microsatellite loci, with an average of 2.8 to 3.5 alleles per locus. Average values of observed and expected heterozygosity were 0.95±0.09 and 0.64±0.02 respectively. None of the tests of linkage disequilibrium were significant between each pair of loci and no deviation from Hardy-Weinberg equilibrium were detected to test for heterozygote deficiency within populations...

María Inés Trucco, Claudio César Buratti
Taxonomically, Argentine mackerels were first considered as Scomber japonicus marplatensis and later as Scomber japonicus Houttuyn 1782, although, in the last years, different studies have suggested that South Atlantic mackerel species belongs to Scomber colias Gmelin 1789. These latter results, incorporated in the main fish databases (FishBase and Catalog of Fishes), promoted a phylogenetic study using cytochrome c oxidase I (COI) gene sequences taken from the Barcode of Life (FISH-BOL) database. Thus, 76 sequences of S...

Many studies have investigated misregulation of miRNAs relevant to multiple sclerosis (MS) pathogenesis. Abnormal miRNAs can be used both as candidate biomarker for MS diagnosis and understanding the disease miRNA-mRNA regulatory network. In this comprehensive study, misregulated miRNAs related to MS were collected from existing literature, databases and via in silico prediction. A multi-staged data integration strategy (including the construction of miRNA-mRNA regulatory network and systematic data analysis) was conducted in order to investigate MS related miRNAs and their regulatory networks...

Diarrheal diseases still remain health problem worldwide and out of many bacteria responsible for, Shigella and pathogenic Escherichia cause the most diarrheas in the world. Shigella cause bacterial dysenteries and shigellosis through invasion where the most effective proteins for pathogenesis is Ipac. Critical virulence protein for ETEC infection is CFA/I with two subunits called cfab and cfae. . Attachment of EHEC is the main step of infection and the protein Intimin plays the key role in this function. Protection against the vast majority of responsible pathogens of diarrheas requires development of the combination vaccine against Shigella , ETEC and EHEC...

Thioredoxins (Trxs) are small ubiquitous oxidoreductase proteins with two redox-active Cys residues in a conserved active site (WCG/PPC) that regulate numerous target proteins via thiol/disulfide exchanges in the cells of prokaryotes and eukaryotes. The isoforms OsTrx23 with a typical active site (WCGPC) and OsTrx20 with an atypical active site (WCTPC) are two Trx h- type isoforms in rice that were previously found to be reduced by NADPH-dependent thioredoxin reductase and GSH/Grx system, respectively. In the present work the reduction of mutants G41TOsTrx23, T55GOsTrx20, K48DOsTrx20 and T55G-K48D OsTrx20 as well as wild types OsTrx23 and OsTrx20 were tested in the reaction containing either NADPH/NTR or glutathione (GSH)...

This study was designed to find out the impact of the variable number of tandem repeats (VNTR) of the tumor necrosis factor receptor 2 (TNFRSF1B) on pulmonary tuberculosis (PTB) risk in an Iranian population. This case-control study was done on 159 PTB patients and 158 healthy subjects. Bi-allelic TNFRSF1B VNTR was genotyped by polymerase chain reaction. Logistic regression analysis revealed no significant association between TNFRSF1B VNTR and PTB risk (P>0.05). Our findings proposed that TNFRSF1B VNTR polymorphism is unlikely to confer susceptibility to PTB...

Stem cell factor (SCF) is a critical protein with key roles in the cell such as hematopoiesis, gametogenesis and melanogenesis. In the present study a comparative analysis on nucleotide sequences of SCF was performed in Humanoids using bioinformatics tools including NCBI-BLAST, MEGA6, and JBrowse. Our analysis of nucleotide sequences to find closely evolved organisms with high similarity by NCBI-BLAST tools and MEGA6 showed that human and Chimpanzee (Pan troglodytes) were placed into the same cluster. By using JBrowse, we found that SCF in Neanderthal had a single copy number similar to modern human and partly conserved nucleotide sequences...

Y chromosome microdeletions are the second genetic cause of male infertility. The incidence of Y chromosome microdeletions can vary considerably depending on several factors, including patient selection criteria, population composition, and diagnostic protocols. They are associated with spermatogenic failure and lead to azoospermia or oligozoospermia. The advance in assisted reproductive technology and intracytoplasmic sperm injection, and the possibility of genetic defect transmission to the next generation make it necessary to improve our knowledge about the various factors leading to spermatogenic impairment...

As an aromatic and colorful plant of substantive taste, saffron (Crocus sativus L.) owes such properties of matter to growing class of the secondary metabolites derived from the carotenoids, apocarotenoids. Regarding the critical role of microRNAs in secondary metabolic synthesis and the limited number of identified miRNAs in C. sativus, on the other hand, one may see the point how the characterization of miRNAs along with the corresponding target genes in C. sativus might expand our perspectives on the roles of miRNAs in carotenoid/apocarotenoid biosynthetic pathway...

Dialysis-related amyloidosis (DRA) is characterized by accumulation of amyloid β2- microglobulin (β2m) in the interstitial matrix. Matrix substances such as heparin have reportedly been strongly implicated in the pathogenesis of dialysis-related amyloidosis. In clinical setting of hemodialysis, two types of heparin, i.e., high and low molecular heparin (H.M.H. and L.M.H.) have been routinely used. Still commonly used is H.M.H., followed by L.M.H. preparations with distinct advantages. Here, we studied that the interaction of native and two amyloidogenic β2m variants: ΔN6β2m and D76N β2m with H...
