Recurrent Constellations of Embryonic Malformations (RCEM): Teratogenicity Linked to Transient Hypoxia and Hormone Pregnancy Tests Agrees With RCEM and Suggest a Reactive Oxygen Species Pathogenesis. [PDF]

Birth Defects Res
ABSTRACT Background No consistent genetic etiology has been found for a group of six different conditions in humans with multiple malformations called “recurrent constellations of embryonic malformations” (RCEM). Recent studies indicate hypoxia/reoxygenation and generation Reactive Oxygen Species (ROS) as an underlying mechanism for RCEM with the ...

‘Relationship between thermal dose and cell death for “rapid” ablative and “slow” hyperthermic heating’

International Journal of Hyperthermia, 2019
Aim: Thermal isoeffective dose (TID) has not been convincingly validated for application to predict biological effects from rapid thermal ablation (e.g., using >55 °C).

Reclamation’s Empirical Method for Estimating Life Loss Due to Dam Failure

E3S Web of Conferences, 2016
The Bureau of Reclamation (Reclamation) estimates life loss resulting from dam failure in support of dam safety risk analysis. To estimate life loss, Reclamation relies primarily on an empirical methodology which is tied to the interpretation of case ...

Improving the documentation quality of point-of-care ultrasound scans in the emergency department

BMJ Open Quality, 2020
A point-of-care ultrasound scan (POCUS) is a core element of the Royal College of Emergency Medicine (RCEM) specialty training curriculum. However, POCUS documentation quality can be poor, especially in the time-pressured environment of the emergency ...

Leadership training in emergency medicine: A national survey. [PDF]

AEM Educ Train
Abstract Background Emergency medicine (EM) is a uniquely stressful environment in which leadership training could improve individual and team performance, patient outcomes, well‐being, and EM career intentions. The primary aim was to evaluate EM‐specific leadership training (EMLeaders) compared to no leadership training.

Study protocol for the SECURE (RAFT-5) study: Service Evaluation of in-hospital Cross-speciality UK adult Rapid sequence intubation Events. [PDF]

Anaesth Rep
Summary Rapid sequence intubation has evolved substantially since its inception over 50 years ago. Contemporary in‐hospital rapid sequence intubation practice includes a combination of variably employed components, many of which lack robust supporting evidence. Real‐world practice and the beliefs underpinning it are poorly characterised. We present the

Identification of a DNA methylation episignature for recurrent constellations of embryonic malformations. [PDF]

Am J Hum Genet
The term “recurrent constellations of embryonic malformations” (RCEM) is used to describe a number of multiple malformation associations that affect three or more body structures.

Study on the effect of hydrogen addition on ignition and combustion of prechamber ignition system

Nihon Kikai Gakkai ronbunshu, 2023
The gas engine for the cogeneration system realizes lean combustion by using prechamber ignition. The fuel properties of natural gas are quantified as methane value, and a small amount of H2 and C2-C4 hydrocarbon fuels affect ignition and combustion ...
