The limitation of polymerase chain reaction (PCR) in diagnosis of lower respiratory tract infections (LRTIs) caused by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis has been a distinguishing colonization from infection. We assess here the usefulness of real-time quantitative PCR (RQ-PCR) performed on lower respiratory tract samples to overcome this problem. Consecu...

Antimicrobial activity of certain species Lactobacillus bacteria were known to produce a type bacteriocin called Plantaricin (Pln). In this study, the PlnF (plnF) gene (666 bp) encoding plantaricin was synthetically constructed based on sequence predefined and valuable amino acid compositions subcloned into pET-28 (+) expression vector. Thereafter transformation recombinant vector BL21 (DE3) co...

PURPOSE The objective of this study was construction of recombinant hEGF-pPIC9 which may be used for expression of recombinant hEGF in following studies. METHODS EGF cDNA was purchased from Genecopoeia Company and used for PCR amplification. Prior to ligation, the PCR product and pPIC9 vector was digested with EcoRI and XhoI and ligated in pPIC9 vector and subjected to colony PCR screening an...

Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N. ceranae is a fairly recently discovered parasite, there is little knowledge of the variation in infection levels among individual workers within a colony. In this study we examined the levels of infec...

Gastric carcinoma is a digestive related malignant tumor with poor diagnosis and prognosis for advanced patients. PTGR1 (prostaglandin reductase 1), as a potential cancer biomarker, has not been reported in gastric carcinoma occurrence. To investigate the role of PTGR1 on gastric carcinoma cells, human PTGR1 was efficiently silenced by lentivirus-mediated system in MGC-803 cells confirmed by qu...

honeybee is a pollinator that has prominent role in agriculture products and nourishment for human. so, the most number of studies like genetic improvement were done on honeybee. recent advances in knowledge of molecular genetics of bee emphasize the potential for using genetic markers to select favored traits. this research was done to determine polymorphism of loci of first foraging age (aff)...

Purpose: Despite the high prevalence of gastric cancer (GC), drug resistance is a major problem for effective chemotherapy. B7-H7 novel member B7 superfamily and expressed in most common cancers. However, role on aggressiveness GC chemosensitivity has remained unknown. Therefore, this study was designed to assess effect suppression using small interference RNA (siRNA) combination with docetaxel...

BACKGROUND Rabies is a fatal viral encephalitic disease that is caused by lyssaviruses which can affect all mammals, including human and bats. In Europe, bat rabies cases are attributed to five different lyssavirus species, the majority of rabid bats being attributed to European bat 1 lyssavirus (EBLV-1), circulating mainly in serotine bats (Eptesicus serotinus). In France, rabies in bats is un...
