Planetary Dominoes - How microbes drive biogeochemical cycles Resource Report Resource Website |
Nadia Szeinbaum, Abbigail Johnson, Thomas Swofford | 10.17504/protocols.io.8wrhxd6 | This protocol describes the step to assemble your own Planetary Domino. We designed this at Georgia Tech for an Astrobiology outreach event called "An Evening of Wonder", which we organized as part of AbGradCon2018. The goal of this activity was to introduce how microorganisms drive many geochemical cycles and how they are interconnected. Each domino piece corresponds to a bacerial functional role/"trophic" role (i.e., aerobic heterotrophs, anaerobic metal reducers, etc.) contains substrates on one side and products on the other. The idea is to find how they can be connected, like pieces of a domino. | NASA Postdoctoral Program Fellow at Georgia Tech, Georgia Institute of Technology, [Image Alleviation] | 1 | 2019 | Nadia Szeinbaum, Abbigail Johnson, Thomas Swofford 2019.

Standard Operating Procedure for Culture Identification and Differentiation of Bordetella species Resource Report Resource Website |
Adria D. Lee, Pamela K. Cassiday, Lucia C. Pawloski, Kathleen M. Tatti, Monte D. Martin, Elizabeth C. Briere, M. Lucia Tondella, Stacey W. Martin, The Clinical Validation Study Group | 10.17504/protocols.io.kvtcw6n | The appropriate use of clinically accurate diagnostic tests is essential for the detection of pertussis, a poorly controlled vaccine-preventable disease. The purpose of this study was to estimate the sensitivity and specificity of different diagnostic criteria including culture, multi-target polymerase chain reaction (PCR), anti-pertussis toxin IgG (IgG-PT) serology, and the use of a clinical case definition. An additional objective was to describe the optimal timing of specimen collection for the various tests. Clinical specimens were collected from patients with cough illness at seven locations across the United States between 2007 and 2011. Nasopharyngeal and blood specimens were collected from each patient during the enrollment visit. Patients who had been coughing for ≤ 2 weeks were asked to return in 2-4 weeks for collection of a second, convalescent blood specimen. Sensitivity and specificity of each diagnostic test were estimated using three methods—pertussis culture as the “gold standard,” composite reference standard analysis (CRS), and latent class analysis (LCA). Overall, 868 patients were enrolled and 13.6% were B. pertussis positive by at least one diagnostic test. In a sample of 545 participants with non-missing data on all four diagnostic criteria, culture was 64.0% sensitive, PCR was 90.6% sensitive, and both were 100% specific by LCA. CRS and LCA methods increased the sensitivity estimates for convalescent serology and the clinical case definition over the culture-based estimates. Culture and PCR were most sensitive when performed during the first two weeks of cough; serology was optimally sensitive after the second week of cough.Timing of specimen collection in relation to onset of illness should be considered when ordering diagnostic tests for pertussis. Consideration should be given to including IgG-PT serology as a confirmatory test in the Council of State and Territorial Epidemiologists (CSTE) case definition for pertussis. | Lee AD, Cassiday PK, Pawloski LC, Tatti KM, Martin MD, Briere EC, Tondella ML, Martin SW, obotCVSG (2018) Clinical evaluation and validation of laboratory methods for the diagnosis of Bordetella pertussis infection: Culture, polymerase chain reaction (PCR) and anti-pertussis toxin IgG serology (IgG-PT).

anemia, iron defficency anemia and amaranth trial in Ethiopia Resource Report Resource Website |
Alemselam Orsango | 10.17504/protocols.io.bhzbj72n | SummaryIntroduction: Malnutrition is a public health problem in Ethiopia. Malnutrition can affect children’s cognitive, behavioral, and motor development. Further, healthy development and educational achievement can be compromised due to micronutrient deficiencies including iron deficiency. Different studies show that amaranth grain has better levels of macro and micronutrients especially iron to address the widespread malnutrition problem than other frequently used crops. This useful plant is widely grown in the research area but is considered as a weed rather than a food crop by the community. Furthermore, adequate research has not been conducted in Ethiopia on amaranth’s potential to contribute to reducing the malnutrition problem. This research is initiated to look at amaranth and its potential in reducing iron deficiency anemia among children. The research will inform the public at large, policymakers, and academicians as it deals with an underutilized nutritious crop that has the potential to contribute to reducing the malnutrition problem in the country. Objective: To assess the iron deficiency status of children and to evaluate the effect of amaranth containing bread consumption on the anthropometry and iron deficiency status of children in the age of 24.0-59.9 months. Methodology: A cross-sectional study and a randomized controlled trial will be done. For the survey, random sampling will be used to select 340 children. Hemoglobin, serum ferritin, C- reactive protein, and anthropometric measurements will be taken and used as the baseline data for the experimental study. In the randomized controlled trial, 100 children with a hemoglobin level of less than 11 mg /dl and above 7 mg/dl (mild and moderate anemia) will be recruited into the trial after informed consent. Severely ill individuals will be referred to as Hawassa Referal Hospital. Kebele-stratified simple random sampling will ensure 1:1 allocation to each group. Sequentially numbered, opaque, sealed envelopes will be used to assure concealment of allocation. The study subjects and parents (other caregivers in the absence of parents) will be kept uniformed about the trial allocation. Statistical analysis will be done using the latest SPSS version and ENA for SMART software. The survey will present descriptive statistics including frequencies, means, ranges and demographic characteristics of the population. The trial will be analyzed according to the intention-to-treat principles using logistic crude and site adjusted regression models with a mean difference in Hemoglobin as the primary outcome measure. Conclusion: This research project has the potential to be hypothesis generating and will inform policy makers and scientists about amaranth’s potential to combat malnutrition specifically iron deficiency in the area.

Drosophila Egg Dechorionation Resource Report Resource Website |
Katy Monteith | 10.17504/protocols.io.vcze2x6 | Vale Lab | This protocol describes how to make an egg dechorionator using available lab equipment before describing how to successfully use the egg dechorionator to remove the outer chorion layer from a Drosophila egg. Egg dechorionation allows cellular analysis, quantitative microinjection and the rearing of developing offspring in a gnotobiotic or axenic environment. This protocol is written with the use of dechorionated eggs for rearing fruit flies in a gnotobiotic or axenic environment in mind. Therefore sterile techniques are described. For cellular analysis and/or quantitative microinjection the protocol can be followed but with a less stringent sterile procedure where unneccesary. | University of Edinburgh | 1 | 2018 | Katy Monteith 2018.

PCR-RFLP protocols for genotyping VEGF-A rs28357093 Resource Report Resource Website |
Caroline Christine Pincela da Costa , Nayane Soares de Lima, Rodrigo da Silva Santos, Angela Adamski da Silva Reis | 10.17504/protocols.io.bqvymw7w | Molecular Pathology Laboratory | The VEGF-A gene encodes a homonymous protein, responsible for regulating angiogenesis and vascular permeability. In addition, in the central nervous system, it acts as a neurotrophic factor, stimulating neurogenesis and cell survival. VEGF-A rs28357093 is located in the promoter region of the gene. There are few studies with this polymorphism, with no reports on the consequences. However, it is in a regulatory region, important for the control of gene transcription, and may influence gene and protein expression. In this document, we share our protocol for amplification and enzymatic digestion for this SNP, using the PCR-RFLP technique and silver staining for genotyping analysis. | Molecular Pathology Laboratory, Federal University of Goiás, Institute of Biological Sciences (ICBII), Goiânia, Goiás, Brazil, Molecular Pathology Laboratory, Federal University of Goiás, Institute of Biological Sciences (ICBII), Goiânia, Goiás, Brazil, Molecular Pathology Laboratory, Federal University of Goiás, Institute of Biological Sciences (ICBII), Goiânia, Goiás, Brazil, Molecular Pathology Laboratory, Federal University of Goiás, Institute of Biological Sciences (ICBII), Goiânia, Goiás, Brazil | 1 | 2021 | Caroline Christine Pincela da Costa , Nayane Soares de Lima, Rodrigo da Silva Santos, Angela Adamski da Silva Reis 2021.

A fast and simple fluorometric method to detect cell death in 3D intestinal organoids Resource Report Resource Website |
Konstantin J. Bode, Stefanie Mueller, Matthias Schweinlin, Marco Metzger, Thomas Brunner | 10.17504/protocols.io.78vhrw6 | BioTechniques | This protocol describes a novel fluorometric method for the quantitative measurement of specific organoid cell death. Organoids are stained simultaneously with the cell impermeable nuclear dye propidium iodide and cell permeable Hoechst 33342. While Hoechst allows in-well normalization to cell numbers, propidium iodide detects relative proportion of dead cells independent of hydrogel. Measurement and analysis time, as well as usability are drastically improved in comparison to other established methods. Parallel multiplexing of this method with established assays measuring mitochondrial activity further enhances its applicability in personalized medicine and drug discovery. | Chair of Biochemical Pharmacology, Department of Biology, University of Konstanz, Konstanz, Germany; Co-operative research training school 'Advanced in-vitro test systems for the analysis of cell-chemical interactions in drug discovery and environmental safety (InViTe)', University of Konstanz, Konstanz, Germany, Chair of Biochemical Pharmacology, Department of Biology, University of Konstanz, Konstanz, Germany, Department of Tissue Engineering and Regenerative Medicine (TERM), University Hospital Würzburg, Würzburg, Germany, Translational Centre Regenerative Medicine TLC-RT, Fraunhofer Institute for Silicate Research (ISC), Würzburg, Germany, Chair of Biochemical Pharmacology, Department of Biology, University of Konstanz, Konstanz, Germany | https://www.future-science.com/doi/10.2144/btn-2019-0023 | 1 | 2019 | Konstantin J.
