In this study the spectrophotometric response of the Toluidine Blue O (TBO)-gelatin gel dosimeter irradiated with gamma rays was characterized. Preparation of dyed-gelatin gel takes place in neutral medium; to give eventually gel dosimeter has a sharp absorbance peak at 635 nm that bleaches quantitatively upon irradiation and the colour change can be measured with UV-VIS spectrophotometer. The ...

Introduction: Multiple fields and presence of heterogeneities create complex dose distributions that need three dimensional dosimetry. In this work, we investigated MR-based MAGIC gel dosimetry as a three-dimensional dosimetry technique to measure the delivered dose to bladder and rectum in prostate radiation therapy. Materials and Methods: A heterogeneous slab phantom including bones was made....

Aloe Vera has gained more attention over the last decade due to its reputable, medicinal, and pharmaceutical and food properties. In present research, firstly the different concentrations of pectin and gum acacia were augmented with aloevera gel and the products so prepared were assessed for texture and stickiness. The selected preparation was then supplemented with orange flavour at different ...

Sol-gel derived lead zirconate titanate (PZT) thin films are being investigated for micromechanical applications. A synthesis technique which involves the spin coating of several thin layers followed by rapid thermal annealing to crystallize the perovskite phase and repetition to achieve thicker films is described. Methods of improving the PZT-PZT interfaces between subsequently annealed layers...

We describe a method for the specific isolation of representative N-terminal peptides of proteins and their proteolytic fragments. Their isolation is based on a gel-free, peptide-centric proteomics approach using the principle of diagonal chromatography. We will indicate that the introduction of an altered chemical property to internal peptides holding a free alpha-N-terminus results in altered...
