In studying the interaction between bacteria and host cells in vitro, the latter are frequently cultured on commercially available biotic matrices such as Matrigel® or Geltrex®. To avoid contamination, host cells are commonly grown in the presence of antibiotics. However, we present here the finding that cell culture on such a matrix in the presence of antibiotics interferes with the outcome of subsequent infection experiments by virtue of diminished bacterial survival. By comparing outcomes for penicillin-susceptible and resistant strains of Staphylococcus aureus, we show that residual penicillin remains in the matrix despite the antibiotics' withdrawal from culture...

BACKGROUND/OBJECTIVES: Electronic medical records (EMR) can improve quality healthcare, patient safety and streamline workflow to improve efficiency of a department. Despite the known benefits and difficulties of EMR systems, there is limited data on the impact and definable effectiveness it can have within a dermatology unit. We present an outpatients' EMR known as an electronic handover system (EHS) from its inception, delivery and audit of its use in evaluating the true impact. METHODS: An audit of the EHS was conducted from 1 March to 31 August 2014...

Electrohydrodynamic spraying (EHS) has recently gained popularity for microencapsulation of cells for applications in cell delivery and tissue engineering. Some of the polymers compatible with EHS are alginate, chitosan, and other similar natural polymers, which are subject to ionotropic or physical gelation. It is desirable to further extend the use of the EHS technique beyond such polymers for wider biofabrication applications. Here, building upon our previous work of making PEG microspheres via EHS, we utilized the principles of EHS to fabricate cell-laden polyethylene glycol (PEG) hydrogel microspheres...

Epoxide hydrolases (EHs) are enzymes that have high biotechnological interest for the fine and transformation industry. Several of these enzymes have enantioselectivity, which allows their application in the separation of enantiomeric mixtures of epoxide substrates. Although two different families of EHs have been described, those that have the α/β-hidrolase folding are the most explored for biotechnological purpose. These enzymes are functionally very well studied, but only few members have three-dimensional structures characterised...

Epoxide hydrolases (EHs) are present in all living organisms. They have been extensively characterized in mammals; however, their biological functions in plants have not been demonstrated. Based on in silico analysis, we identified AtEH1 (At3g05600), a putative Arabidopsis thaliana epoxide hydrolase possibly involved in cutin monomer synthesis. We expressed AtEH1 in yeast and studied its localization in vivo. We also analyzed the composition of cutin from A. thaliana lines in which this gene was knocked out...

PURPOSE: Since the introduction of the first prosthetic mesh for abdominal hernia repair, there has been a search for the "ideal mesh." The use of preclinical or animal models for assessment of necessary characteristics of new and existing meshes is an indispensable part of hernia research. Unfortunately, in our experience there is a lack of consensus among different research groups on which model to use. Therefore, we hypothesized that there is a lack of comparability within published animal research on hernia surgery due to wide range in experimental setup among different research groups...

Oprozomib is an oral proteasome inhibitor currently under investigation in patients with hematologic malignancies or solid tumors. Oprozomib elicits potent pharmacological actions by forming a covalent bond with the active site N-terminal threonine of the 20S proteasome. Oprozomib has a short half-life across preclinical species and in patients due to systemic clearance via metabolism. Potential for drug-drug interactions (DDIs) could alter the exposure of this potent therapeutic therefore a thorough investigation of pathways responsible for metabolism is required...

Food allergies affect an estimated 15 million persons in the United States (1), and are responsible for approximately 30,000 emergency department visits and 150-200 deaths each year (2). Nearly half of reported fatal food allergy reactions over a 13-year period were caused by food from a restaurant or other food service establishment (3). To ascertain the prevalence of food allergy training, training topics, and practices related to food allergies, CDC's Environmental Health Specialists Network (EHS-Net), a collaborative forum of federal agencies and state and local health departments with six sites, interviewed personnel at 278 restaurants...

The central dogma of RNA processing has started to totter. Single genes produce a variety of mRNA isoforms by mRNA modification, alternative polyadenylation and splicing. Different isoforms, even those that code for the identical protein, may differ in function or spatiotemporal expression. One option of how this can be achieved is by the selective recruitment of trans-acting factors to the 3'-untranslated region of a given isoform. Recent innovations in high-throughput RNA-Sequencing methods allow deep insight into global RNA regulation, whereas novel imaging-based technologies enable researchers to explore single RNA molecules during different stages of development, in different tissues and different compartments of the cell...

Systematic reviews of scientific literature are important for mapping the existing state of research and highlighting further growth channels in a field of study, but systematic reviews are inherently tedious, time consuming, and manual in nature. In recent years, keyword co-occurrence networks (KCNs) are exploited for knowledge mapping. In a KCN, each keyword is represented as a node and each co-occurrence of a pair of words is represented as a link. The number of times that a pair of words co-occurs in multiple articles constitutes the weight of the link connecting the pair...
