Obestatin and ghrelin are peptides with antagonistic effects on glucose homeostasis in the body. As is well known, glucose metabolism disorders are at the root of many diseases. One of the best known are diabetes type II and obesity, which are currently a global problem. Moreover, the excess of adipose tissue may lead to consequences such as neoplasm within the gastrointestinal tract[1]. The role of obestatin and ghrelin therefore seems highly important. The knowledge gained in this area can be used to find therapeutic or preventive solutions.</p> Beata Szczepaniak Copyright (c) 2020 Letters in Oncology Science http://creativecommons.org/licenses/by-nd/4.0 2020-06-18 2020-06-18 17 2 8 16 10.21641/los.2020.17.2.182 The radioimmunotherapy in lymphoma https://journals.wco.pl/los/article/view/181 <p>Radioimmunotherapy (RIT) is a targeted therapy combining radiobiological and immunological characteristics. RIT has been considered effective in terms of B-cell non-Hodgkin's lymphomas (NHL) treatment and it can be used as the main therapy or as the element of the combined RIT and chemotherapy. Despite RIT’s effectiveness in NHL therapy, it is still rarely used.</p> Mikołaj Kuta Agata Pietrzak Copyright (c) 2020 Letters in Oncology Science http://creativecommons.org/licenses/by-nd/4.0 2020-07-09 2020-07-09 17 2 1 7 10.21641/los.2020.17.2.181
