#1
David Sweet, Julian Marsden, Kendall Ho, Christina Krause, James A Russell
Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

The radiation exposure in the cath lab of patients, cardiologists, and nurses was measured during three consecutive periods of 8 weeks. The first 8 weeks the baseline radiation exposure was obtained. In the second period standard incidences for coronarography and frame rate were changed, without compromising the image quality of the examination. In the third period, a pelvic shield covered the lower part of the patient. This pilot quality project demonstrates that further significant reduction in radiation exposure of 37% is possible for patients...

Cesar Palma, Robert David Deegan
In traditional electrowetting-on-dielectric devices droplet are moved about a substrate using electric fields produced by an array of discrete electrodes. Here we show that a drop can be driven across a substrate with a localized light beam by exploiting the photoelectrowetting effect, a light-activated variant of electrowetting-on-dielectric. Droplet transport actuated by photoelectrowetting eliminates the need for electrode arrays and the complexities entailed in their fabrication and control, and offers a new approach for designing lab-on-a-chip applications...

Alcohol intoxication may affect self-reports of alcohol use and related constructs, such as impulsivity and dependence symptoms. Improved knowledge about potential systematic reporting biases induced by alcohol, e.g. through disinhibition, may be relevant for the assessment of intoxicated individuals both in clinical routine and research. We therefore randomly assigned 54 socially drinking males aged 18 to 19 without lifetime diagnosis of DSM-IV alcohol dependence to one of two experimental arms: either placebo infusion at day 1 and alcohol infusion at day 2, or vice versa...

The Smurf Assay (SA) was initially developed in the model organism Drosophila melanogaster where a dramatic increase of intestinal permeability has been shown to occur during aging (Rera et al. , 2011). We have since validated the protocol in multiple other model organisms (Dambroise et al. , 2016) and have utilized the assay to further our understanding of aging (Tricoire and Rera, 2015; Rera et al. , 2018). The SA has now also been used by other labs to assess intestinal barrier permeability (Clark et al...

Emma Davidson Peiris, Raghav Wusirika
CYP24A1 is an enzyme that inactivates vitamin D. Loss-of-function mutations in this enzyme are rare but have been linked with idiopathic infantile hypercalcemia as well as adult-onset nephrocalcinosis and nephrolithiasis. Genetic testing for this mutation should be considered in the presence of calciuria, elevated serum calcium, elevated 1,25-dihydroxyvitamin D, and suppressed parathyroid hormone. We present a case with these lab findings as well as an elevated 25-hydroxyvitamin D/24,25-dihydroxyvitamin D ratio in whom compound heterozygous CYP24A1 mutations were found...

Le Zhang, Jingxin Zhang, Kai-Chee Loh
Effects of activated carbon (AC) supplementation on anaerobic digestion (AD) of food waste were elucidated in lab- and pilot-scales. Lab-scale AD was performed in 1 L and 8 L digesters, while pilot-scale AD was conducted in a 1000 L digester. Based on the optimal dose of 15 g AC per working volume derived from the 1 L digester, for the same AC dosage in the 8 L digester, an improved operation stability coupled with a higher methane yield was achieved even when digesters without AC supplementation failed after 59 days due to accumulation of substantial organic intermediates...

The dynamic microtubule cytoskeleton plays fundamental roles in the growth and development of plants including regulation of their responses to environmental stress. Plants exposed to hyper-osmotic stress commonly acclimate, acquiring tolerance to variable stress levels. The underlying cellular mechanisms are largely unknown. Here, we show, for the first time, by in vivo imaging approach that linear patterns of phospholipase Dδ match the localization of microtubules in various biological systems, validating previously predicted connection between phospholipase Dδ and microtubules...

Achieving nitrite accumulation was considered as the prerequisite of ANAMMOX, which hindered the application of ANAMMOX. In this study, total inorganic nitrogen (TIN) removal during the partial/complete nitrification was studied in a lab-scale sequencing batch reactor (SBR) for treating domestic wastewater. The results showed TIN was removed by denitrification, ANAMMOX and N2 O emission during the partial/complete nitrification. AOB, AOA, Nitrobacter (NB), Nitrospira (NS), AnAOB and DNB were coexisted in the partial/complete nitrification...

Nanowire sensors offer great potential as highly sensitive electrochemical and electronic biosensors because of their small size, high aspect ratios, and electronic properties. Nevertheless, the available methods to fabricate carbon nanowires in a controlled manner remain limited to expensive techniques. This paper presents a simple fabrication technique for sub-100 nm suspended carbon nanowire sensors by integrating electrospinning and photolithography techniques. Carbon Microelectromechanical Systems (C-MEMS) fabrication techniques allow fabrication of high aspect ratio carbon structures by patterning photoresist polymers into desired shapes and subsequent carbonization of resultant structures by pyrolysis...

Ross Ferguson, Vasanta Subramanian
Three dimensional (3D) culture of mammalian cells is emerging as a powerful new tool to understand organogenesis as well as serve as models for diseases with implications for therapeutic evaluation. 3D cultures are referred to variously as spheroid, organoids or embryoid bodies. While many methods exist for large scale production of embryoid bodies or other spheroid cell aggregates, either at controlled sizes using microwell/micropatterned plates or uncontrolled sizes in suspension dishes, very few protocols exist for medium throughput analysis of differentiation at the histological level...

To study the characteristics of temporal summation (TS) and conditioned pain modulation (CPM) in fibromyalgia (FM) patients, we systematically searched Pubmed and EMBASE for studies using TS or CPM comparing FM patients to healthy controls. We computed Hedge's g, risk of bias, sensitivity analysis and meta-regression tests with 10000 Monte-Carlo permutations. Twenty-three studies (625 female/23 male FM patients and 591 female/81 male healthy controls) were included. The meta-analyses showed an effect size of 0...

Nutrient recovery performance utilising an electrodialysis (ED) process was quantified in a 30-cell pair pilot reactor with a 7.2 m2 effective membrane area, utilising domestic anaerobic digester supernatant, which had been passed through a centrifuge as a feed source (centrate). A concentrated product (NH4 -N 7100 ± 300 mg/L and K 2490 ± 40 mg/L) could be achieved by concentrating nutrient ions from the centrate wastewater dilute feed stream to the product stream using the ED process. The average total current efficiency for all major cations over the experimental period was 76 ± 2% (NH4 -N transport 40%, K transport 14%)...

Cigarette butts are a common form of litter that is often deposited on soil, where toxins from butts may affect soil-dwelling organisms. We examined possible toxicity of cigarette butts to the woodland snail Anguispira alternata using a toxicity study with cigarette butt effluent and a lab-based habitat choice experiment in which snails could feed or rest on areas with different butt densities. No mortality occurred during the 32-day toxicity study, which used six effluent concentrations ranging from 0 to 4butts/l (0 to 0...

As energy metabolism in the brain is largely oxidative, the measurement of cerebral metabolic rate of oxygen consumption (CMRO 2 ) is a desirable biomarker for quantifying brain activity and tissue viability. Currently, PET techniques based on oxygen isotopes are the gold standard for obtaining whole brain CMRO 2 maps. Among MRI techniques that have been developed as an alternative are dual calibrated fMRI (dcFMRI) methods, which exploit simultaneous measurements of BOLD and ASL signals during a hypercapnic-hyperoxic experiment to modulate brain blood flow and oxygenation...

In recent era, nanoparticles (NPs) are widely used in food, medicine and body implants. Besides it's wide use being a foreign particle it may have some noxious effect on the body. To understand the mechanistic role of NPs toxicity, Drosophila appeared to be a superior model organism. Toxicity of several nanoparticles were accessed using Drosophila. The NPs, after oral route of exposure enter into the gut, crosses the barrier of peritrophic membrane and induces apoptosis. The toxicity of NPs within gut resulted in developmental delay, with decrease in pupa count, fly hatching along with weight loss...
