چکیده
Methods Avidin was either directly conjugated to chitosan (virus–biotin– avidin-material; VBAM) or indirectly docked on biotinylated chitosan surfaces (virus–biotin–avidin–biotin-material; VBABM) to tether biotinylated adenovirus. Enzyme-linked immunosorbent assay (ELISA) and spectroscopic analysis were performed to demonstrate the binding profiles. Biotinalkaline phosphatase and biotinylated adenovirus were used as different sized particles to evaluate binding efficiencies and were compared by the Sips isotherm adsorption method. Scanning electron microscopy (SEM) examination illustrated virus distribution, and the transduction efficiency was determined by in vitro cell transduction.

Evaluation of Osteopontin Gene Expression in Endometrium of Diabetic Rat Models Treated with Metformin and Pioglitazone
Objective Osteopontin (Opn) is one of the co-factors which participates in cell adhesion and invasion during implantation process. Increased incidence of spontaneous abortion is reported in diabetic women. Several reports have shown Opn gene expression changes in diabetic condition in several tissues. Therefore, this study was designed to evaluate the effects of diabetes on Opn gene expression ...
متن کاملMutations in the RpoB Gene of Multidrug-Resistant Mycobacterium Tuberculosis Isolates from Semarang, Indonesia
ABSTRACTTuberculosis is an infectious disease which occurs widely in the world and becomes one of the top 10 causes of death worldwide. Mutations of the RpoB gene cause the resistance of Mycobacterium tuberculosis to rifampicin that contributes to the occurrence of MDR-TB. This study aimed to determine the pattern of rpoB gene polymorphisms in the MDR M. tuberculosis in Semarang, Indonesia. Mos...

Aspergillus fumigatus is a saprophyte fungus, widely spread in a variety of ecologicalniches and the most prevalent aspergilli responsible for human and animal invasiveaspergillosis. The first step to develop novel and efficient therapies is the identificationand understanding of the key tolerance and virulence factors of pathogens. The mainfocus of the present study is to perform the similarit...
متن کاملDetection of gene expression and sequence analysis of chicken class II trans activator (CIITA)
BACKGROUND:Class II transactivator (CIITA) is a dominanttranscriptional element, controlling numerous genes in theimmune system. CIITA is expressed in a constitutive pattern inantigen presenting cells although its expression can occur inother cell types. Since the revelation of CIITA, there have beenconsiderable advances toward understanding its role as anactivator of MHC II genes in humans and...
