  12. Договор на тема „Третиране на ракови клетки и солидни тумори чрез подходящ избор на електрични импулси” Д0 02/178, финансиран от Националния Фонд за научни изследвания с кординатор проф., д.б.н. Яна Цонева, И-т по биофизика биомедицинско инженерство, БАН приключи на 30 юни 2012 г.Title “Treatment of cancer cells and solid tumors by suitable choice of electrical pulses”, DО 02/178

  13. The project was scientifically and biothecnologically related to a development of new approaches for electrotreatment of tumor cells and solid tumors by multidisciplinary researches 1. Institute of Biophysics and Biomedical Engineering, BAS 2. Dermatologic Clinic at Specialized Hospital for Active Treatment of Oncology, Sofia 3.Institute of Electronics, BAS

  14. The new type electroporators Chemipulse III and Chemipulse IV were designed and constructed. In the last version three elements (electroporator, QRS synhronisator and device for patient current) were incorporated in one body. The new instrument is with battery supply, enhanced protection against electrical hazards both for patient and the physician. By using the electroporator with QRS synchronization the patients with pacemakers and heard problems can be treated also. Data collection of the pulse parameters and the impedances of treated patients with surface tumors could be used to support the optimization of the voltage shock setting and the evaluation of the procedure effectiveness. The constructed electroporators are small and portable

  15. Electrochemotherapy of patients included in the studies are with clinically and cytologically verified diagnosis Carcinoma basocellulare, Carcinoma spinocellulare, Kaposi sarkoma and Mycosis fungoides, in stage I (T1N0M0) and the application and study was approved by the ethics committee of the hospital and all patients gave written information consent before beginning treatment. All treatments were carried out at Dermatologic Clinic at Specialized Hospital for Active Treatment of Oncology, Sofia. The total number of successfully treated by electrochemotherapy patients with device developed during the project was 49, number of the treated lesions was 60. The majority of the lesions are at the visible places at the body and the collection of the material from the lesions for the following of the effect of therapy will lead to the scars the new method light induced spectroscopy was applied.

  18. Fundamental studies are related to the increasing the amount of the drugs into the cancer cells or tumors thus reducing toxicity in normal tissue and increasing the therapeutic response. Investing the mechanisms of DNA transfer, adhesion behavior of cancer cells proliferation and invasiveness we achied higher efficiency in electricity (chemo) therapy of tumors.

  24. Ин витро изледвания- Да се създадат условия за локално увеличение на концентрацията на конвенционални противотуморни лекарства в ракови клетки чрез електропорация. Използване на наночастици за лечение на тумори.- Да се използват възможностите на електропорацията за въвеждане на лекарства като милтефозин и еруфозин (нова група алкилфосфохолини- противотуморни и противо възпалителни агенти) в керетиноцитни клетки HaCaT (ин витро модел на псориасис). - Изучаване на механизмите на действие на електропорацията при ко-култури (соматични и неопластични клетки) – Целта е да се изясни как взаимодействат ракови и здрави клетки при ръба на тумора след електрохимиотерапия, тъй като макар и рядко рецидив на заболявнето се появява именно на това място.- Използване на 2D и 3D култири с оглед доближаване на условията на електропорацията на ниво тъкан.

  25. Клинични изследвания- Да се оптимизират протоколите на електрохимиотерапия на кожни тумори и оздравителния ефект при тумори, разположени на различни места по тялото. Да се конкретизира персонализиран подход за лечение на кожни тумори.- Използване на неинвазивни физични подходи за проследяване на оздравителния процес на човешки кожни тумори.

  26. Електроди1. Нови електроди, съобразени с размера и локализацията на тумора и подсигурени с подходяща изолоция.
