the aim of this study was to prepare liposomes of acyclovir (acy) by thin layer evaporation (tle) and reverse phase evaporation (rev) methods. twenty-seven batches of liposomes from each method were prepared using technique of three variables at three levels (33) factorial design. drug/lipid (molar ratio), hydration volume and hydration time were considered three independent variables in tle me...

identification and use of more efficient enzymes in the food and pharmaceutical industries is the focus of many researchers. the aim of this study was to search for a new bacterial strain capable of producing high levels of pullulanase applicable to biotechnology, the starch bioprocessing and food industries. a new pullulan hydrolyzing bacillus strain was isolated and designated sdk2. morpholog...

Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...

EEG recordings made during concurrent fMRI are confounded by the pulse artefact (PA), which although smaller than the gradient artefact is often more problematic because of its variability over multiple cardiac cycles. A better understanding of the PA is needed in order to generate improved methods for reducing its effect in EEG-fMRI experiments. Here we performed a study aimed at identifying t...
