An important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. Ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. Nowadays, the use of compounds such as essential oils (EOs) and nanoparticles is applicable in microbiology studies. The main objective of this experiment was to study the s...

Staphylococcus aureus is an opportunistic pathogen able to colonize the upper respiratory tract and skin surfaces in mammals. Methicillin-resistant S. aureus ST398 is prevalent in pigs in Europe and North America. However, the mechanism of successful pig colonization by MRSA ST398 is poorly understood. To study MRSA colonization in pigs, an ex vivo model consisting of porcine nasal mucosa expla...

Methamphetamine (MET) is a stimulant and one of the most abused drugs in worldwide. MET could cause several organ toxicity such as cardiotoxicity. Oxidative stress has been proposed as the main mechanism for MET toxicity. Propofol as a sedative-hypnotic agent has antioxidant property. In this study, we used propofol for attenuating of MET-induced cardiotoxicity in rats. The groups (six rats in ...

Abstract Bioactive compounds extracted from plant are of great value for those enterprises interested in the use natural products; tissue culture techniques guarantee a reliable and constant biomass production. Hop ( Humulus lupulus L.), with its wealth bioactive compounds, may represent an invaluable resource. The present study focused on characterization vitro -derived leaves roots two hop ty...

Lung branching morphogenesis depends on mesenchymal-epithelial tissue interactions. Keratinocyte growth factor (KGF) has been implicated to be a regulator of these tissue interactions. In the present study, we investigated the role of KGF in early rat lung organogenesis. Reverse transcriptase-polymerase chain reaction analysis revealed KGF mRNA expression in the mesenchymal component of the 13-...

The initiation of osteogenesis in the mandibular mesenchyme of the embryonic chick at 7 days is dependent upon an epithelial induction which occurs in the mandible up to the fourth day in ovo. In the present study, transfilter tissue recombinations were used to study this inductive mechanism. The epithelial and mesenchymal components of the mandibles were separated before the completion of the ...

The presence of fungal and bacterial contamination in vitro propagation is a determinant the culture establishment. biocide PPM (Plant Preservative Mixture™) has been utilized to control contamination. According manufacture’s label, it heat-stable, broad-spectrum product, non-selective, that affects directly microorganisms without causing damage plant cells. purpose this study was evaluate infl...
