PURPOSE OF REVIEW: The nine members of the proprotein convertase family play major physiological roles during development and in the adult, and their dysregulation leads to various diseases. The primary objective of this article is to review recent findings on the clinical importance of some of these convertases concentrating mostly on PCSK9, the ninth member of the convertase family. This includes the transcriptional and translational regulation of PCSK9, its ability to enhance the degradation of LDL receptor (LDLR), and the implication of PCSK9 in inflammation and sepsis...

BACKGROUND: In 2012, we clarified that the prevalence of food-dependent exercise-induced anaphylaxis (FDEIA) was 0.018% among junior-high students in Yokohama, Japan. Furthermore, although different from FDEIA, one student who had completed oral immunotherapy developed anaphylaxis during exercise after eating causative food. However, there have been few large-scale epidemiological studies of FDEIA in elementary school children, so we conducted the epidemiological study among elementary school children in Yokohama to clarify the frequency and characteristic of FDEIA...

Stroke consists of the loss of cerebral functions resulting from the interruption of blood supply to a region of the brain, and represents the second cause of death and the leading cause of major disability in adults in Europe. Stroke is a very active field of research at preclinical and clinical levels, and Magnetic Resonance Imaging (MRI) is one of the most powerful tools that scientist and clinicians have for the study of the onset, evolution and consequences of this devastating disease, as well as for the monitoring of the success of available treatments, or for the development of novel therapeutic strategies...

BACKGROUND: Preoperative exposure to narcotics has recently been associated with poor outcomes after elective major surgery, but little is known as to how preoperative opioid use impacts outcomes after common, emergency general surgical procedures (EGS). METHODS: A high-volume, single-center analysis was performed on patients who underwent EGS from 2012 to 2013. EGS was defined as the seven emergent operations that account for 80% of the national burden. Preoperative opioid use was defined as having an active opioid prescription within 7 days prior to surgery...

Point-of-care ultrasound (POCUS) is becoming an integral part of anesthesia practice throughout the world. Despite the growing interest in POCUS among trainees and faculty, POCUS training is variable among universities across Canada. This suggests a need for curriculum development and standardization. International guidelines for Emergency Medicine and Critical Care have common frameworks and may be used as a reference to model anesthesia-specific curricula. The Royal College of Anaesthetists of the United Kingdom currently offers the only nationally approved POCUS curriculum for anesthesia and critical care trainees...

BACKGROUND: Combination of laparoscopic approach with ERAS protocol in colorectal surgery allows for an early discharge. However there is a risk that some of the discharged patients are developing, asymptomatic at the time, infectious complications. This may lead to a delay in diagnostics and proper treatment introduction. We aimed to assess the usefulness of preoperative plasma albumin concentration and their changes as indicators of infectious complications in patients undergoing colorectal cancer surgery...

Fibromyalgia syndrome (FMS) is a common and complex chronic pain condition. Exercise is recommended in the management of the FMS; however, people with FMS often find exercise exacerbates their condition and causes overwhelming fatigue. The objective of this study was to explore the perceptions of fatigue and sleep dysfunction, and exercise in people with FMS. Three, 60-90 min focus groups were conducted with people with FMS (n = 14). Participants were recruited from patient support groups who had experienced therapeutic exercise in the management of their condition...

From an evolutionary perspective keratan sulphate (KS) is the newest glycosaminoglycan (GAG) but the least understood. KS is a sophisticated molecule with a diverse structure, and unique functional roles continue to be uncovered for this GAG. The cornea is the richest tissue source of KS in the human body but the central and peripheral nervous systems also contain significant levels of KS and a diverse range of KS-proteoglycans with essential functional roles. KS also displays important cell regulatory properties in epithelial and mesenchymal tissues and in bone and in tumour development of diagnostic and prognostic utility...

The Dolphin Morbillivirus (DMV) genome from the first Mediterranean epidemic (1990-'92) is the only cetacean Morbillivirus that has been completely sequenced. Here, we report the first application of next generation sequencing (NGS) to morbillivirus infection of aquatic mammals. A viral isolate, representative of the 2006-'08 Mediterranean epidemic (DMV_IZSPLV_2008), efficiently grew on Vero.DogSLAMtag cells and was submitted to whole genome characterization by NGS. The final genome length was 15,673 nucleotides, covering 99...

BACKGROUND/AIMS: Arsenic trioxide (ATO) is a known anti-acute promyelocytic leukemia (APL) reagent, whose clinical applications are limited by its serious cardiac toxicity and fatal adverse effects, such as sudden cardiac death resulting from long QT syndrome (LQTS). The mechanisms of cardiac arrhythmia due to ATO exposure still need to be elucidated. Long non-coding RNAs (lncRNAs) are emerging as major regulators of various pathophysiological processes. This study aimed to explore the involvement of lncRNAs in ATO-induced LQTS in vivo and in vitro...

One of the major challenges in today's agriculture is to achieve enhanced plant growth and biomass even under adverse environmental conditions. Recent advancements in genetics and molecular biology have enabled identification of a complex signaling network contributing towards plant growth and development on the one hand and abiotic stress response on the other. As an outcome of these studies, three major approaches have been identified having a potential to improve biomass production in plants under abiotic stress conditions...

Nonencapsulated Streptococcus pneumoniae (NESp) is an emerging human pathogen that colonizes the nasopharynx and is associated with noninvasive diseases such as otitis media (OM), conjunctivitis, and nonbacteremic pneumonia. Since capsule expression was previously thought to be necessary for establishment of invasive pneumococcal disease (IPD), serotype-specific polysaccharide capsules are targeted by currently licensed pneumococcal vaccines. Yet, NESp expressing oligopeptide binding proteins AliC and AliD have been isolated during IPD...

Escherichia coli K1 strains are major causative agents of invasive disease of the new born. The age dependency of infection can be reproduced in the neonatal rat. Colonization of the small intestine following oral administration of K1 bacteria leads rapidly to invasion of the blood circulation; bacteria that avoid capture by the mesenteric lymphatic system and evade antibacterial mechanisms in the blood may disseminate to cause organ-specific infections such as meningitis. Some E. coli K1 surface constituents, in particular the polysialic acid capsule, are known to contribute to invasive potential but a comprehensive picture of the factors that determine the fully virulent phenotype has not so far emerged...

REVIEW
Matthew J Price
Atrial fibrillation (AF) is associated with a substantial risk of thromboembolic stroke. Although long-term treatment with warfarin or the non-vitamin K oral anticoagulants can reduce this risk, such therapy is underutilized, and safe and consistent long-term treatment can be challenging. Transcatheter left atrial appendage (LAA) closure is an emerging alternative to long-term oral anticoagulation. Long-term follow-up of randomized clinical trials demonstrate that Watchman LAA closure provides significant reductions in hemorrhagic stroke, cardiovascular death, and all-cause mortality compared with continued warfarin therapy...
