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...

In this study, passive detectors for Pb were prepared by immobilizing powdered rock phosphate in agarose beads. Rock phosphate has been used to treat Pb-contaminated waters and soil by fixing the metal as an insoluble pyromorphite mineral. Under lab conditions, Pb was rapidly adsorbed from aqueous solution by the beads over time, consistent with the acidic dissolution of rock phosphate, the precipitation of pyromorphite within the pore space of the agarose gel matrix, and surface exchange reactions. Net accumulation of Pb occurred when beads were exposed to simulated periodic releases of Pb over time...

Anorexia nervosa has the highest mortality rate among all psychiatric illnesses, as it can result in significant psychopathology along with life-threatening medical complications. Atypical anorexia nervosa is a new variant described in the latest DSM edition, which has much in common with anorexia nervosa and also can result in significant morbidity and mortality. The evolution of the criteria for these illnesses is reviewed, and the two are compared and contrasted in this article. Important labs to monitor for in those with these illnesses, along with an emphasis on the monitoring of vital signs and weight, are reviewed here...

Infection and inflammation of the endometrium after calving compromise uterine health, contributing to decreased reproductive efficiency in dairy cows. Twenty multiparous cows were distributed in two groups and treated intra-vaginally with a combination of lactic acid bacteria (LAB) composed by Lactobacillus rhamnosus, Pedioccocus acidilactici, and Lactobacillus reuteri, or with a sterile carrier (CON) twice per week during 3 wk. At the slaughterhouse, vaginal and endometrial swabs were taken for E. coli and Lactobacillus quantification...

ETHNOPHARMACOLOGICAL RELEVANCE: The twigs and bark of Cinnamomum cassia Presl (Lauraceae) are widely used in traditional Chinese medicine in the treatment of tumor, abdominal pain, dysmenorrhea, digestive system disease and inflammatory diseases. The aim of this study was to determine the inhibitory effect of the essential oil from the twigs of Cinnamomum cassia Presl (EOCC) on uterine contraction in vitro and in vivo. MATERIALS AND METHODS: The Institute of Cancer Research (ICR) mouse uterine contraction was induced by oxytocin (OT) exposure following estradiol benzoate pretreatment...

Molecular techniques to detect organisms in aquatic ecosystems are being gradually considered as an attractive alternative to standard laboratory methods. They offer faster and more accurate means of detecting and monitoring species, with respect to their traditional homologues based on culture and microscopic counting. Molecular techniques are particularly attractive when multiple species need to be detected and/or are in very low abundance. This paper reviews molecular techniques based on whole cells, such as microscope-based enumeration and Fluorescence In-Situ Hybridization (FISH) and molecular cell-free formats, such as sandwich hybridization assay (SHA), biosensors, microarrays, quantitative polymerase chain reaction (qPCR) and real time PCR (RT-PCR)...

BACKGROUND: Acute appendicitis is one of the most common causes of acute abdominal pain prompting emergency department (ED) visits. It is critical for the physicians to promptly and accurately diagnose acute appendicitis. The present study aimed to evaluate the diagnostic efficacy of Doppler ultrasonography (USG) in patients with acute appendicitis and compare this new method with other commonly used radio-diagnostic tools. METHODS: All patients who were diagnosed with acute appendicitis at the Kecioren Training and Research Hospital ED and later underwent appendectomy between October 2012 and April 2013 were included in the study...

The tsunami caused by the Great East Japan Earthquake on March 11, 2011 disturbed coastal environments in the eastern Tohoku region in Japan. Numerous terrestrial materials, including anthropogenic organic compounds, were deposited in the coastal zone. To evaluate the impacts of the disaster, we analyzed PCBs, LABs, PAHs, and hopanes in mussels collected from 12 locations in the east of Tohoku during 2011-2015 (series A) by GC-ECD or GC-MS and compared them with results from mussels collected from 22 locations around Japan during 2001-2004 (series B)...

Carbon allocation demands from root-nodulating nitrogen-fixing bacteria (NFB) can modulate the host plant's chemical phenotype, with strong bottom-up effects on herbivores. In contrast to well-studied rhizobia, the effects of other important NFB on plant chemistry and herbivory are much less understood. Here, combining field surveys in the Oregon Coast Range, USA with laboratory experiments, we analyzed how N2-fixing Frankia bacteria influenced plant growth, chemistry, and herbivory on Alnus rubra (red alder) seedlings...

Many studies have been performed in recent years in the field of firearm examination with the goal of providing an objective method for comparisons of fired cartridge cases. No published research to support the number of test fires needed to represent the variability present within the impressions left on a cartridge case could be found. When a suspect firearm is submitted to a firearm examiner, typically two to four test fires are performed. The recovered cartridge cases are compared to each other to determine which characteristics from the firearm are reproducing, and then compared to any cartridge cases collected at a crime scene...

To establish in silico model to predict the structural insight into the metabolic bioactivation pathway of xenobiotics, we considered two specific and one non-specific mammary procarcinogen [e.g., dibenzo[a,l]pyrene (DBP), 7,12-dimethylbenz[a]anthracene (DMBA), and benzo[a]pyrene (BP)]. The CYP1A1, 1B1, 2C9, 1A2 and 2B6 reported in wet-lab studies to actively metabolize DBP also showed strong binding energies (kcal/mol) of -11.50, -10.67, -10.37, -9.76 and -9.72, respectively, with inhibition constants ranging between 0...

The investigations on seasonal and spatial distribution of 12 selected wastewater-marking pharmaceuticals (WWMPs) belonging to different therapeutic classes were conducted in three major urban rivers of Yangpu District, Shanghai, East China. The potential mechanisms for the removal of WWMPs in the rivers were also experimentally investigated. The detection frequencies of most WWMPs were in the range of 56-100%, with the exception of clofibric acid, which was not detected during the storm events. The median concentrations ranged from not detected to 5821 ng/L (caffeine) and the maximum concentration was 8662 ng/L, found in caffeine...

The aim of this study was to evaluate the probiotic potential of lactic acid bacteria (LAB) strains isolated from Horreh. Some probiotic properties, e.g., resistance to acid, bile tolerance, antibacterial activity, and antibiotic susceptibility, were investigated. A total of 140 Gram-positive and catalase-negative isolates from Horreh were subjected to identification and grouping by cultural methods and the 16S rRNA sequencing. The new isolates were identified to be Lactobacillus (fermentum, plantarum, and brevis) Weissella cibaria, Enterococcus (faecium and faecalis), Leuconostoc (citreum and mesenteroides subsp...

OBJECTIVES: Work in chemical laboratories is associated with exposure to chemicals, of which some are known or suspected carcinogens. A cohort study of laboratory workers in Stockholm followed until 1992 showed an excess of hematolymphatic malignancies in chemical laboratories and an excess of breast cancer among women working for more than 10 years in such laboratories. The follow-up of this cohort has now been extended by 20 years. METHODS: The cohort comprised 2245 female laboratory workers who are employed for >1 year from 1950 to 1989...
