Abstract | Irreversible electroporation (IRE) is a novel therapy that employs short high intense electric field to destroy the cytoskeletal structure and ablate the tissue, especially the tumor tissue. Compared to traditional treatment, IRE is a nonthermal therapy, which is not limited by the thermal sink near the blood vessel. However, the experiment of animals and the clinical trials all reveal that there is muscle contraction during IRE. The way using high frequency pulses was proposed to reduce the muscle contraction, while the killing effect of the high frequency pulse is still a question to be solved. Therefore, in this study the influence of the different frequency on the killing effect are discussed. The human epidermic cells (Hacat) and the skin cancer cell (GLL19) are investigated in this study. The range of the burst frequency in this paper is 250kHz~2MHz, and the on time of each burst is 100us. There is one burst persecond, and the amplitude of the electric field is 1000V/cm. The outcome between the single pulse and the high frequency burst is similar. However, there are still some differences of the outcome among the different frequency. The 250kHz has the best killing effect while the 1MHz has the worst outcome. The mechanism of the high frequency IRE is different from the traditional parameters IRE, which need the further study. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
