fibrillation is a hazardous phenomenon in cardiac muscle and so any new work towards the understanding of this process is important to the development of new methods in diagnosis and therapy. in this work we have used surface and intra cardiac ecgs of patients with chronic atrial fibrillation (af). by means of the blind source separation (bss) algorithm, which is a well-known method in signal p...

introduction: cardiac glycosides such as digoxin or digitoxin are the natural products that are traditionally used to increase cardiac contractile force in patients with heart failure and cardiac arrhythmias. it has been shown that digoxin can directly inhibit the cell proliferation and lead to cell apoptosis. present study was conducted to analyze the effect of digoxin in the cohorts of mesenc...

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

I have read the article entitled “Is cardiac resynchronisation therapy feasible, safe and beneficial in the very elderly?” by Olechowski, et al. with great interest, recently published in Journal of Geriatric Cardiology. The investigators reported that implantation of cardiac resynchronisation therapy (CRT) is feasible and safe in very elderly despite extensive co-morbidity. I would like to emp...

Cancer is the second leading cause of death in the United States and has become a health problem worldwide. The reported incidence of new cancer cases is estimated at 19.3 million, with a mortality rate of 10 million in the world in 2020. There are several therapeutic approaches for cancer, including chemotherapy. Chemotherapy is consuming anti-neoplastic drugs, alone or in combination. However...
