#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...

Ningning Xu, Jianxin Liu, Peiqiang Yu
Advanced vibrational molecular spectroscopy has been developed as a rapid and non-destructive tool to reveal intrinsic molecular structure conformation of biological tissues. However, this technique has not been used to systematically study flaking induced structure changes at a molecular level. The objective of this study was to use vibrational molecular spectroscopy to reveal association between steam flaking induced CHO molecular structural changes in relation to grain CHO fractionation, predicted CHO biodegradation and biodigestion in ruminant system...

REVIEW
Galina Matafonova, Valeriy Batoev
Over the last decade, ultraviolet light-emitting diodes (UV LEDs) have attracted considerable attention as alternative mercury-free UV sources for water treatment purposes. This review is a comprehensive analysis of data reported in recent years (mostly, post 2014) on the application of UV LED-induced advanced oxidation processes (AOPs) to degrade organic pollutants, primarily dyes, phenols, pharmaceuticals, insecticides, estrogens and cyanotoxins, in aqueous media. Heterogeneous TiO2-based photocatalysis in lab grade water using UVA LEDs is the most frequently applied method for treating organic contaminants...

Our focus of attention naturally fluctuates between different sources of information even when we desire to focus on a single object. Focused attention (FA) meditation is associated with greater control over this process, yet the neuronal mechanisms underlying this ability are not entirely understood. Here, we hypothesize that the capacity of attention to transiently focus and swiftly change relates to the critical dynamics emerging when neuronal systems balance at a point of instability between order and disorder...

Rodentia is a species-rich group with diversified modes of life and diets. Although rodent skull morphology has been the focus of a voluminous literature, the functional significance of its variations has yet to be explored in live animals. Myomorphous rodents, including murids, have been suggested to represent "high-performance generalists." We measured in vivo bite force in 14 species of wild and lab-reared murid rodents of various sizes and diets to investigate potential morphofunctional differences between them...

This work investigates the potential conversion of spent coffee grounds (SCG) into lactic acid (LA). SCG were hydrolysed by a combination of dilute acid treatment and subsequent application of cellulase. The SCG hydrolysate contained a considerable amount of reducing sugars (9.02 ± 0.03 g l-1 , glucose; 26.49 ± 0.10 g l-1 galactose and 2.81 ± 0.07 g l-1 arabinose) and it was used as a substrate for cultivation of several lactic acid bacteria (LAB) and also lactic acid producing Bacillus coagulans. Among the screened microorganisms, Lactobacillus rhamnosus, CCM 1825 was identified as the most promising producer of LA on SCG hydrolysate...

BACKGROUND: There is little published data about human plant exposures reported to US poison control centers (PCCs). METHODS: A retrospective chart review of all reported plant exposures to a single regional PCC between January 1, 2003 and December 31, 2010 was done to understand better the characteristics of plant exposure cases. Specific generic plant codes were used to identify cases. Recorded variables included patient demographics, plant involved, exposure variables, symptoms, management site, treatments, and outcome...

Current therapeutic strategies to reduce scarring in full thickness skin defect offer limited success due to poor understanding of scar tissue formation and the underlying signaling pathways. There is an urgent need to develop human cell based in vitro scar tissue models as animal testing is associated with ethical and logistic complications and inter-species variations. Pro-inflammatory cytokines play critical role in regulating scar development through complex interplay and interaction with the ECM and corresponding signaling pathways...

Salvia miltiorrhiza is a medicinal plant widely used in the treatment of cardiovascular and cerebrovascular diseases. Hydrophilic phenolic acids, including rosmarinic acid (RA) and lithospermic acid B (LAB), are its primary medicinal ingredients. However, the biosynthetic pathway of RA and LAB in S. miltiorrhiza is still poorly understood. In the present study, we accomplished the isolation and characterization of a novel S. miltiorrhiza Hydroxyphenylpyruvate reductase (HPPR) gene, SmHPPR, which plays an important role in the biosynthesis of RA...

Primary human hepatocytes (PHH) are commonly used for in vitro studies of drug-induced liver injury. However, when cultured as 2D monolayers, PHH lose crucial hepatic functions within hours. This dedifferentiation can be ameliorated when PHH are cultured in sandwich configuration (2Dsw), particularly when cultures are regularly re-overlaid with extracellular matrix, or as 3D spheroids. In this study, the six participating laboratories evaluated the robustness of these two model systems made from cryopreserved PHH from the same donors considering both inter-donor and inter-lab variability and compared their suitability for use in repeated-dose toxicity studies using 5 different hepatotoxins with different toxicity mechanisms...

Near-field x-ray refraction (phase) contrast is unavoidable in many lab-based micro-CT imaging systems. Quantitative analysis of x-ray refraction (a.k.a. phase retrieval) is in general an under-constrained problem. Regularizing assumptions may not hold true for interesting samples; popular single-material methods are inappropriate for heterogeneous samples, leading to undesired blurring and/or over-sharpening. In this paper, we constrain and solve the phase-retrieval problem for heterogeneous objects, using the Alvarez-Macovski model for x-ray attenuation...

The reduction of effluents deriving from analytical control is a serious concern in the nuclear industry, for both production and R & D units. In this work we report an alternative methodology for the standard UV-Vis absorbance analyses for acti-nides concentration monitoring along the PUREX (Plutonium Uranium Redox Extraction) process. This methodology, based on Photonic Lab-on-a-chip (PhLoC) technology, enables drastic sampling reduction down to a few microliters, and simulta-neously allows to track concentrations over several orders of magnitude while maintaining a detection linearity range...

INTRODUCTION: Invasive fungal infections are an increasing cause of mortality and morbidity in high risk patient populations such as those on immunosuppressive therapy. Triazole antifungals are recommended for the prevention and treatment of such infections. The aim of this study was to develop and validate a simple, sensitive and robust LCMS/MS method for the simultaneous analysis in human plasma of three frequently used antifungal drugs: voriconazole, posaconazole, and itraconazole...

An 18 year old boy attended a dermatology clinic outside our hospital and diagnosed with psoriasis. His skin lesions over both ankles (Fig. 1) did not improve at all with potent local steroids twice for 3 months, then 3 times daily for another 3 months. His dermatologist talked to him about using methotrexate and asked for liver function tests before starting the systemic therapy. His ALT and AST were doubled. The patient came to our Hepatology clinic worried about his elevated liver enzymes. We asked for viral markers...

Overdoses of prescription or illicit opioids claimed the lives of 116 Americans each day in 2016, and the crisis continues to escalate. As healthcare systems evolve to address the crisis, the potential of pharmacists to make a positive difference is significant. In addition to utilizing available prescription drug monitoring programs to help prevent diversion of opioids, practicing pharmacists can be alert for signs of opioid misuse by patients (e.g., multiple prescriptions from different physicians) as well as inappropriate prescribing or hazardous drug combinations that physicians may not be aware of (e...

BACKGROUND: Tests for direct oral anticoagulants (DOAC) are not widely available. The perception that they are difficult to be run and are subjected to large between-laboratory variation makes their implementation difficult. AIMS: We carried out proficiency-testing surveys for DOAC within the activity of the external quality-assessment scheme of the Italian Federation of Thrombosis Centers. DESIGN: Participants were provided with coded freeze-dried plasmas without or with graded concentrations of the three main DOAC and asked to measure PT, APTT, thrombin time and DOAC concentrations by dedicated tests...
