Optimization of ultrasound assisted extraction of anthocyanins from red cabbage using Taguchi design method.

There is a growing demand for developing suitable and more efficient extraction of active compounds from the plants and ultrasound is one of these novel methodologies. Moreover, the experimental set up to reach an appropriate condition for an optimum yield is demanding and time consuming. In the present study, Taguchi L9 orthogonal design was applied to optimize the process parameters (output power, time, temperature and pulse mode) for ultrasound assisted extraction of anthocyanins from red cabbage and the concluding yield of anthocyanin was measured by pH differential method.

Engraftment of plasma membrane vesicles into liposomes: A new method for designing of liposome-based vaccines.

Objectives: One of the major challenges in the field of vaccine design is choosing immunogenic antigens which can induce a proper immune response against complex targets like malignant cells or recondite diseases caused by protozoan parasites such as leishmaniasis. The aim of this study was to find a way to construct artificial liposome-based cells containing fragments of target's cell membrane. This structure not only mimics the real biological properties of proteins in the cell membrane of target cells, but also may induce the required immune responses, which culminate in eradication of target cells.
