Sodium Polystyrene Sulfonate-Induced Gastric Pneumatosis: A Rare Side Effect.

Kayexalate has been used in the USA since 1975 for the treatment of hyperkalemia. Prior case reports have shown that sorbitol added to kayexalate has been known to cause rare side effects of colonic necrosis. We present a unique case report of gastric pneumatosis as a complication of kayexalate.

In-Hospital Outcomes of Patients with Acute Decompensated Heart Failure and Cirrhosis: An Analysis of the National Inpatient Sample.

Introduction: Heart failure increases morbidity and mortality in patients admitted for cirrhosis. Our objective was to determine if patients with acute decompensated heart failure (ADHF) and cirrhosis would have increased mortality, hospital length of stay (LOS), and total hospital charges compared to patients with only ADHF. There is also a paucity of data regarding the influence of gender, race, ethnicity, insurance, and cirrhosis-related complications on mortality, hospital length of stay, and total hospitalization charges.

RNase P protein subunit Rpp29 represses histone H3.3 nucleosome deposition.

In mammals, histone H3.3 is a critical regulator of transcription state change and heritability at both euchromatin and heterochromatin. The H3.

Single cell analysis of RNA-mediated histone H3.3 recruitment to a cytomegalovirus promoter-regulated transcription site.

Unlike the core histones, which are incorporated into nucleosomes concomitant with DNA replication, histone H3.3 is synthesized throughout the cell cycle and utilized for replication-independent (RI) chromatin assembly. The RI incorporation of H3.

Single cell analysis of transcriptional activation dynamics.

Background: Gene activation is thought to occur through a series of temporally defined regulatory steps. However, this process has not been completely evaluated in single living mammalian cells.

Methodology/principal Findings: To investigate the timing and coordination of gene activation events, we tracked the recruitment of GCN5 (histone acetyltransferase), RNA polymerase II, Brd2 and Brd4 (acetyl-lysine binding proteins), in relation to a VP16-transcriptional activator, to a transcription site that can be visualized in single living cells.

Error-prone DNA repair system in enteroaggregative Escherichia coli identified by subtractive hybridization.

Enteroaggregative Escherichia coli (EAEC) are etiologic agents of diarrhea. The EAEC category is heterogeneous, but most in-depth experimentation has focused on prototypical strain, 042. We hypothesized that 60A, another EAEC strain, might posses virulence or fitness genes that 042 does not have.
