Pseudomyxoma peritonei (PMP) is a subtype of mucinous adenocarcinoma mainly restricted to the peritoneal cavity and most commonly originating from the appendix. The genetic background of PMP is poorly understood and no targeted treatments are currently available for this fatal disease. While RAS signaling pathway is affected in most if not all PMP cases and over half of them also have a mutation in the GNAS gene, other genetic alterations and affected pathways are, to a large degree, poorly known. In this study, we sequenced whole coding genome of nine PMP tumors and paired normal tissues in order to identify additional, commonly mutated genes and signaling pathways affected in PMP...

In this study, we aimed to determine factors that cause appendix perforations and to identify the role of physicians and patients in contributing to the cause of these perforations. This study was conducted between April 2010 and May 2015 and included 64 patients with perforated appendicitis. Patients' medical records were examined for factors that might have contributed to perforation, and the roles of patients and physicians in perforation appendicitis were evaluated. The perforation rate of patients with appendicitis was 16...

Despite a large focus on the use of vitrification to cryopreserve embryos in recent years, there are still arguments for the use of slow freezing for the cleavage-stage embryo. Having said this, there are lessons to be learned from the process of vitrification that could be applied to slow freezing to improve post-thaw survival and ultimately clinical pregnancy rates. Specifically, increasing the concentration of sucrose in the freezing solution from 0.1 to 0.2 M and subsequently increasing the sucrose concentrations in thawing solutions could prove beneficial...

Cryopreservation of gametes and embryos is a growing technique in numerous reproductive fields including human-assisted reproduction. With improved understanding of embryo physiology and optimized culture conditions, there are now more embryos than ever to vitrify for potential use in subsequent cycles. Many gametes and embryos have been cryopreserved in open systems, but there are concerns with regard to contamination from the liquid nitrogen and also cross-contamination between patients' germplasm. The development of the Rapid-i™, a closed vitrification device that does not use direct contact with liquid nitrogen during vitrification or subsequent storage, will be discussed as well as clinical protocols for human oocytes and embryos...

INTRODUCTION: Appendicitis is a prevailing cause of acute abdomen, but is often difficult to diagnose due to its wide range of symptoms, anatomical variations, and developmental abnormalities. Urological disorders of the genitourinary tract may be closely related to appendicitis due to the close proximity of the appendix to the genitourinary tract. This review provides a summary of the urological complications and simulations of appendicitis. Both typical and urological symptoms of appendicitis are discussed, as well as recommended diagnostic and treatment methods...

Flooding is a very costly natural hazard in the UK and is expected to increase further under future climate change scenarios. Flood defences are commonly deployed to protect communities and property from flooding, but in recent years flood management policy has looked towards solutions that seek to mitigate flood risk at flood-prone sites through targeted interventions throughout the catchment, sometimes using techniques which involve working with natural processes. This paper describes a project to provide a succinct summary of the natural science evidence base concerning the effectiveness of catchment-based 'natural' flood management in the UK...

Appendicular diverticulosis is one of the very rare diseases which is also difficult to diagnose, especially clinically, due to its silent course and non-specific symptoms. It comes under the notation usually due to its complications like diverticulitis or perforation, but sometimes it also presents with acute appendicitis. This report describes a 44-year male patient who presented with the complain of right iliac fossa pain and was clinically diagnosed as acute appendicitis; but intraoperatively, it was found that the appendix also had diverticulosis along with appendicitis...
