Gary Cline, John Stack 10.17504/protocols.io.yz9fx96 Mouse Metabolic Phenotyping Centers Procedure used to measure the activity of Aspartate Amino Transferase (AST). AST activity is measured by the enzymatically coupled reactions of AST (to form oxaloacetate from aspartate and α-ketoglutarate) and malate dehydrogenase (conversion of oxaloacetate to malate with oxdiation of NADH to NAD). The rate of NAD formation is monitored by the change in absorbance at 340 nm.

Sam Li 10.17504/protocols.io.699hh96 BioLegend BioLegend MojoSort™ nanobeads work in commonly used separation columns, based on our internal research as well as validation by external testing by academic labs. This simple protocol consists of following the MojoSort™ protocol to label the cells with pre-diluted MojoSort™ reagents and using the columns as indicated by the manufacturer.Note: Due to the properties of our beads, it may be possible to use far fewer beads than with other commercial suppliers. We recommend a titration to find the best dilution factor. However, as a general rule, dilutions ranging from 1:3 to 1:20 for the Nanobeads can be used. Please contact BioLegend Technical Service ([email protected]) if further assistance is needed.

Hasheemah Afaneh , Gabrielle Gonzalez, Olivia Sugarman, Edward Trapido, Susanne Straif-Bourgeois, Evrim Oral, Ashley Wennerstrom 10.17504/protocols.io.bka6kshe Louisiana State University Health Sciences Center - New Orleans As of 2017, there were more than three million individuals in the United States infected with Hepatitis C virus (HCV) [1]. Because most cases are asymptomatic, leading to a higher rate of unreported cases, this number is suspected to be much higher. Furthermore, there is a rise of HCV cases, and this increase documented since 2013 is primarily due to injection drug transmission alongside the rise of the opioid epidemic [2]. The Centers for Disease Control and Prevention (CDC) encourages HCV testing for all adults at least once in their lifetime, and those that test positive for HCV should be linked to treatment [3]. In 2013, only 13%-18% of patients with HCV received treatment in that year, indicating that there are barriers to treatment, such as lack of treatment acceptance, co-existing conditions, extensive treatment, side-effects, and access to treatment[4]. Thus, health disparities may ensue and the eradication of HCV as a public health issue becomes even more challenging. Edlin and Winkelstein (2014) suggested that to achieve optimal HCV eradication, social determinants of health, such as homelessness, need to be addressed [5]. Because there is room for improvement in linkage-to-care opportunities, it is important to explore whether linkage-to-care interventions address social determinants of health, and if so, which ones, to obtain a better understanding of what may help improve patient outcomes.References: U.S. Department of Health and Human Services. 2019.Retrieved June 11, 2020, fromhttps://www.hhs.gov/opa/reproductive-health/fact-sheets/sexually-transmitted-diseases/hepatitis-c/index.htmlCentersfor Disease Control and Prevention(CDC). 2019.

Ales Mishchenko, Herve Glotin 10.17504/protocols.io.iyjcfun The method described here is from the PLoS ONE paper entitled "Joint time delay and Doppler passive acoustic 3D tracking, applied to studies of bats in natural habitats". This method detects acoustic events (possible bat calls) and filters them according to their consistency with each other as well as with extracted kinematics of the bat. This allows to filter out false detections, related to echoes and noise, improves the reconstruction of bats trajectories and allows to study bats behavior.This method (with another parameters) can be also potentially applied to the extraction of the trajectory of any fast moving objects, in particular, sound-emitting machinery, such as trajectories of cars before and after accident, and many others.This protocol (together with bat-related parameters, such as frequency ranges, intervals between calls, etc) is designed to reproduce the method of Joint time delay and Doppler passive acoustic 3D tracking in a case of tracking bats by an array of 4 ultrasonic microphones. , 1 2017 Ales Mishchenko, Herve Glotin 2017.

Machine learning approach yields epigenetic biomarkers of food allergy: A novel 13-gene signature to diagnose clinical reactivity
 
Resource Report
Resource Website
Ayush Alag 10.17504/protocols.io.x7pfrmn Current laboratory tests have a less than 50% accuracy in distinguishing between people who have food allergies (FA) and those who are merely sensitized to foods, resulting in the use of expensive and potentially dangerous Oral Food Challenges. Our study presents a purely-computational machine learning approach, conducted using DNA Methylation (DNAm) data, to accurately diagnose food allergies and find genes that are strong biomarkers of the disease. We built two deep learning classifiers with twelve CpG-input features each that achieved perfect accuracy and an AUROC of 1 on the completely hidden cross-validation cohort. In addition, 24 additional classifiers were created that each had an average cross-validation accuracy of 98.35%. These 26 classifiers yielded a total of 18 unique CpGs, which mapped to 13 genes that are strong epigenetic biomarkers of FA.Biological enrichment on the 13-gene signature yielded new insights. Notably, our FA-discriminating genes were strongly associated with the immune system, which helps validate our findings. Seven of the 13 genes overlapped with previous food-allergy and DNAm studies.Previous studies have also created a perfect classifier for this dataset, but they used a 96-CpG input feature set built on both data-driven and a priori biological insights. Our study is an improvement on previous work because it maintains a perfect classification accuracy using only 18 highly discriminating CpGs (0.005% of the total available features). In machine learning, simpler models, as used in our study, are preferred over more complex ones (all other things being equal).In addition, our completely data-driven approach eliminates the need for \textit{a priori} information and allows for generalizability to DNAm classification problems in other disease areas, which may result in novel gene associations or accurate diagnostic tests for those diseases.

B.R. Cunningham, J.R. Brum, S.M. Schwenck, M.B. Sullivan, S.G. John 10.17504/protocols.io.c8pzvm VERVE Net, Sullivan Lab Purpose: This method for the enumeration of aquatic viruses is a low-cost alternative to the commonly used filter-mount method. Briefly, fluorescently-stained samples are wetmounted directly onto slides for epifluorescence microscopy after an optional chemical flocculation concentration step used for samples with anticipated virus concentrations of 7 viruses mL-1 (samples with >5×107 viruses mL-1 do not require this concentration step prior to analysis). Virus concentration in the wet-mounted sample is determined from the ratio of viruses to microsphere beads, which are added at a known concentration. This wet-mount method for enumerating viruses is significantly less expensive than the filter-mount method (i.e., the cost of microsphere beads per sample is ~500-fold lower than the cost of one filter per sample), and is appropriate for rapid, precise and accurate enumeration of aquatic viruses over a wide range of viral concentrations encountered in field and laboratory samples. The only limitation of this method is that samples with virus concentrations ≤1×106 viruses mL-1 cannot be enumerated, as the abundance of viruses is too low for efficient enumeration.Figure 1.

Comparison of Two Lipid Emulsions on Interleukin-1β, Interleukin-8 and Plasma Fatty Acid Composition in Infants Post Gastrointestinal Surgery: A Randomized Trial
 
Resource Report

Meta Herdiana Hanindita 10.17504/protocols.io.bknmkvc6 Surgical intervention in infants is associated with postoperative sepsis and severe outcomes due to immature immune system1. Gastrointestinal surgery induces excessive cytokine secretion, which may lead to increased postoperative mortality and morbidity2. Parenteral nutrition plays a crucial role in pediatric patients who undergo gastrointestinal surgery3. Intravenous lipid emulsion is an integral part of parenteral nutrition because it contains high energy density and low osmolarity, hence becoming the main source of energy and essential fatty acids4,5. Fatty acid determines structural integrity and fluidity of cell membrane, and it has been proven that fatty acid helps to regulate expression of various genes and modulate cell-signaling pathway, which occurs during inflammation6,7. The current standard type of IVFE is a 50:50 mixture of medium chain triglyceride (MCT) and long chain triglyceride (LCT)8. This type of emulsion is rich in ω-6 and contains high levels of linoleic acid (LA, C18:2 ω -6) and alpha-linolenic acid (ALA, C18:3 ω-3). According to several studies, ω-6 is associated with impaired cell-mediated immunity and higher potential risk of elevated proinflammatory markers and severe inflammatory response. This mechanisms may lead to the increase in mortality, morbidity, duration of treatment, and recovery time in patients who undergo gastrointestinal surgery9-11.Calder (2010) showed that the structure modification of fatty acids may alter their functions7. Some studies have shown that the addition of ω-3 in soy oil-based fat emulsion may improve patients’ outcome by modulating inflammatory response3,4,12. ω-3, particularly eicosapentaenoic acid (EPA) and doxohexanoic acid (DHA), is a competitive enzyme inhibitor of arachidonic acid (AA). ω-3 has potential anti-inflammatory properties by inhibiting AA pathway and generating inflammatory eicosanoids, such as prostaglandine E3, thromboxane A3 and leukotriene B5, which are considered less inflammatory. Up to this time, the effect of ω-3-enriched intravenous fat emulsion compared to standard intravenous fat emulsion on the IL-1b ,IL-8 levels and plasma fatty acid composition in infants who undergo gastrointestinal surgery has yet to be elucidated. The purpose of this study is aimed to investigate the effect of ω-3-enriched intravenous fat emulsion compared to standard intravenous fat emulsion on the IL-1b ,IL-8 levels and plasma fatty acid composition in infants who undergo gastrointestinal surgeryTrial Design:Type: Parallel randomized controlled trialAllocation ratio:1:1Framework: SuperiorityAim of the study:The purpose of this study is to investigate the effect of ω-3-enriched intravenous fat emulsion compared to standard MCT/LCT intravenous fat emulsion on the IL-1b ,IL-8 levels and plasma fatty acid composition in infants who undergo gastrointestinal surgery.Research QuestionWill the Intravenous omega-3 enriched-fat emulsion make difference in IL-1β, IL-8 and fatty acid composition when compared to standard intravenous MCT/LCT fat emulsion?PICO approach:P: Patients underwent gastrointestinal surgery.

With the help of a librarian, we will design a search strategy using Boolean features through PubMed, Embase, and Google Scholar using terms like tibia, graft, mechanical, shear, etc, restricted to English language. We will upload the results in EndNote, eliminate the duplicates, and scan the titles for potential inclusion. We will export the chosen titles into Rayyan QCRI website for abstract review and selection of articles for full text review. A summary and a critical appraisal of the extracted evidence will follow. Thestudy protocol is registered in Open Science Framework, https://osf.io/mequ6. Article summary: this study maps and summarizes the available evidence on the biomechanics of donor site following proximal tibial autogenous bone graft harvest.Strengths and limitations of this studyThe strength of this study relies on its systematic review of the evidence based on gold standard methods and protocol registrations. This study suggests there is need for further investigation into the biomechanics of proximal tibia autogenous bone harvest.This study is a scoping review and harbors the inherent limitations of such studies.
