However, the biological relevance of its unique pseudo-SAP/SAP-box domain, which transmits DNA modulating activities in vitro, remains largely speculative. As hypothesis-driven mutations failed to yield DNA-binding null (DBN) mutants, we combined random mutagenesis with the Bacterial Growth Inhibition Screen (BGIS) to overcome this bottleneck. Re-expression of a DEK-DBN mutant in newly established human DEK knockout cells failed to reduce the increase in nuclear size as compared to wild type, indicating roles for DEK-DNA interactions in cellular chromatin organization. Our results extend the functional roles of DEK in metazoan chromatin and highlight the predictive ability of recombinant protein toxicity in E. coli for unbiased studies of eukaryotic DNA modulating protein domains. Zero-balance ultrafiltration (Z-BUF) is considered a significant method during cardiopulmonary bypass (CPB), and has always received support regarding its key role in monitoring electrolyte abnormalities including potassium and sodium derangements and managing them which occur commonly during CPB. With Z-BUF procedure's impact on controlling electrolyte abnormalities, we conducted a study in order to find out the most efficient solution regarding managing potassium and sodium levels to be selected as replacement fluid in Z-BUF out of the three commonly used normal saline, ringer's and ringer's lactate. a randomized clinical trial study was conducted and 90 patients were divided into three groups. Each group was given a certain solution out of the three normal saline (Z-BUF-NS), ringer's (Z-BUF-R), and ringer's lactate (Z-BUF-RL) with allocation concealment strategy then potassium and sodium levels were measured at 5 points of the whole procedure prior to CPB and after anesthesia induction, cardioplegic solution's deliv
