To discuss the management options of retained products of conception (RPOC) with increased vascularity where simple dilatation and curettage may lead to life threatening haemorrhage and endanger the life of the patient. We present a series of three cases that had RPOC with hyper vascularity and were managed with different approaches. A brief review of management options is discussed. Out of thr...

OBJECTIVE Hysteroscopic removal of retained products of conception (RPOC) may allow complete removal of RPOC and decreased rates of intrauterine adhesions (IUA) when compared to the traditional blind curettage. The aim of this meta-analysis is to examine the current evidence regarding the use of hysteroscopy for treatment of RPOC. STUDY DESIGN A literature search was conducted in December 201...

The genes coding for the beta (rpoB) and beta' (rpoC) subunits of RNA polymerase are fused in the gastric pathogen Helicobacter pylori but separate in other taxonomic groups. To better understand how the unique fused structure evolved, we determined DNA sequences at and around the rpoB-rpoC junction in 10 gastric and nongastric species of Helicobacter and in members of the related genera Woline...

The rpoB and rpoC genes of eubacteria and archaea, coding respectively for the beta- and beta'-like subunits of DNA-dependent RNA polymerase, are organized in an operon with rpoB always preceding rpoC. The genome sequence of the gastric pathogen Helicobacter pylori (strain 26695) revealed homologs of two genes in one continuous open reading frame that potentially could encode one 2890-amino aci...

Background Postpartum bleeding is a component of the normal physiologic process that occurs after delivery or miscarriage. Normally, bleeding decreases over the first postpartum week. When bleeding is excessive and uterine atony has been excluded as a cause, the next most common cause of postpartum bleeding is retained products of conception (RPOC). The placenta usually constitutes the majority...

In this meta-analysis, we assessed cardiac magnetic resonance imaging data to determine the effects of local and remote ischemic postconditioning (LPoC and RPoC, respectively) on structural pathology in ST-segmentel elevation acute myocardial infarction (STEMI). We searched the Pubmed, Embase and Cochrane Library databases up to May 2017 and included 12 randomized controlled trials (10 LPoC and...

We observed that cells lacking Rep and UvrD, two replication accessory helicases, and the recombination protein RecF are cryo-sensitive on rich medium. We isolated five mutations that suppress this Luria-Bertani (LB)-cryo-sensitivity and show that they map in the genes encoding the RNA polymerase subunits RpoB and RpoC. These rpoB (D444G, H447R and N518D) and rpoC mutants (H113R and P451L) were...

Uterine vascular malformations (UVM) leading to postpartum hemorrhage (PPH) are rare. The worldwide literature consists of case reports and small case series, and while the true incidence is unknown, it is likely to represent a very small proportion of causes of PPH. UVM can be congenital but are more commonly acquired when they tend to present with secondary PPH, although in rare instances the...

Zwittermicin A is a novel aminopolyol antibiotic that represents a new structural class of antibiotic and has diverse biological activities, including the suppression of plant disease and the ability to inhibit prokaryotic and eukaryotic cells. To enhance our fundamental understanding and applications of zwittermicin A, we elucidated mechanisms of zwittermicin A resistance in Escherichia coli. ...

Background: To describe the clinical course of women with acute vaginal bleeding and a finding uterine enhanced myometrial vascularity (EVM) suspected retained products conception (RPOC) on ultrasound examination. Methods: A retrospective cohort study including EMV RPOC attending single tertiary medical center between April 2018 to May 2020. Women were identified from records clinics. Demograph...
