In the evolution of life, DNA replication is a fundamental process, by which species transfer their genetic information to their offspring. DNA polymerases, including bacterial and eukaryotic replicases, are incapable of de novo DNA synthesis. DNA primases are required for this function, which is sine qua non to DNA replication. In Escherichia coli, the DNA primase (DnaG) exists as a monomer an...

HIGHLIGHTS Chimeric protein P48-40 of Mycoplasma agalactiae was designed and expressed in E.coli BL21 (DE3). highly soluble form purified with yield 33mg/Lby using Nickel resin. Novel showed high performance for detection specific antibodies 100% sensitivity specificity.

The limited success of IFN-alpha therapy for clinical treatment of transitional cell carcinoma (TCC) has prompted us to investigate the responsiveness of TCC lines to IFN-alpha. The response to IFN-alpha in terms of 561 gene induction, an IFN-stimulated response element-containing IFN-alpha/beta-inducible gene, and IFN-stimulated gene factor 3 (ISGF3) formation was normal in primary human uroth...

Xeroderma pigmentosum (XP) is a skin cancer-prone autosomal recessive disease characterized by inability to repair UV-induced DNA damage. The major form of XP is defective in nucleotide excision repair (NER) and comprises seven complementation groups (A-G). The genes defective in all groups have been identified unambiguously with the exception of group E. The cells of some XP-E patients are def...

BACKGROUND Mycoplasma bovis (M. bovis) is a major, but often overlooked, pathogen documented to cause respiratory disease, mastitis, and arthritis in cattle throughout China since 2008. Here, we report the development of a direct competitive enzyme-linked immunosorbent assay (Dc-ELISA) to detect M. bovis antibody. RESULTS We used a recombinant P48 protein and monoclonal antibody (mAb) 10E. MA...

Sexual reproduction is an obligate step in the life cycle of many parasites, including the causative agents of malaria (Plasmodium). Mixed-species infections are common in nature and consequently, interactions between heterospecific gametes occur. Given the importance of managing gene flow across parasite populations, remarkably little is understood about how reproductive isolation between spec...

Pancreatic cancer (PC) accumulates multiple genetic mutations, including activating KRAS mutations and inactivating TP53, SMAD4 and CDKN2A mutations, during progression. The combination of mutant KRAS with a single inactivating TP53, SMAD4 or CDKN2A mutation in genetically engineered mouse models (GEMMs) showed that these mutations exert different synergistic effects in PC. However, the effect ...

The MTX was converted to nanoparticles by the modified method based on changing pH gradually . For first time NPs+Meropenem complex were prepared and evaluated as a potential tool overcome antimicrobial resistance improve pharmacokinetics of drug, results showed that antibacterial activity (MTX NPs plus MEM) has increased (from 1( µg/ml) >0.5( for p1 , from 2( p10 8( 4( p48).
