VASCULAR ENDOTHELIAL GROWTH FACTOR PLASMA LEVELS IN PATIENTS WITH CANCER OF THE LEFT COLON SUBMITTED TO OPEN OR LAPAROSCOPIC SURGERY Resource Report Resource Website |

This study's purpose was to determine plasma VEGF levels before, during, and after open and laparoscopic colorectal surgery performed for left colon cancer (CD).Patients and methods: a multicenter, prospective, observational, non-randomized study was planned to evaluate samples obtained preoperatively, intraoperatively, and on postoperative days (1, 3, 7, 15, 30). VEGF-A165 values were determined via ELISA. Statistical analysis was a repeated Anova with interactions.Results: the recruitment finished in 4 years (71 patients). Baseline plasma VEGF-A165 mean values (pVmv) resulted not significantly different in patients submitted to laparoscopy (125.4 pg/ml ± 47.7) and laparotomy (116.3 pg/ml ± 28.9). Intraoperatively, the highest difference was registered at the end of operations. In the 30-days postoperative period, the pVmv resulted significantly lower (G-G=0.45) in patients submitted to laparoscopy than in patients submitted to laparotomy (F= 144.6, pConclusions: the trial supports the hypothesis that cancer and surgical trauma are related to production of VEGF-A165 and demonstrates that open surgery, in comparison to laparoscopy, is a stronger promoter of VEGF release. | Department of Life, Health and Environmental Sciences, University of L’Aquila, ITALY., Department of Applied Clinical Sciences and Biotechnology, University of L’Aquila, ITALY, Department of General Surgery P.

Bioinformatic analysis of biomarker genes using metagenomic shotgun sequence datasets Resource Report Resource Website |
Fernando Espinola | 10.17504/protocols.io.u32eyqe | This protocol describes the steps used to analyze shotgun sequences deposited in in Integrated Microbial Genomes and Microbiomes (IMG/M ) by using functional anotation evidences. KEGG orthology terms and pathways are used as evidence.The abundance of each of the corresponding biomarker genes is estimated by calculating the proportion of amino acid sequences assigned to the KO of interest (estimated gene copies, assembled and unassembled metagenomes, as retrieved from IMG/M) and normalized with respect to the total number of sequences assigned to KOs in each metagenome. | Calderoli PA, Espínola FJ, Dionisi HM, Gil MN, Jansson JK, Lozada M (2018) Predominance and high diversity of genes associated to denitrification in metagenomes of subantarctic coastal sediments exposed to urban pollution.

Prakash Lab | 10.17504/protocols.io.fjwbkpe | Foldscope | The printed instructions accompanying each Foldscope kit are very detailed and easy to follow. Even easier is this excellent 14-minute video tutorial for the assembly. I didn't know about the video when I was assembling the Foldscope, and despite carefully following the printed instructions, I still managed to make a few embarrassing mistakes. I am sharing the protocol below with the comments on these mistakes, so others can avoid them. Hopefully, more new users will comment, pinpointing the assembly steps that turned out to be error-prone for them. | http://www.foldscope.com/10kmicroscope-project-blog/2014/10/25/foldscope-instruction-set | 1 | 2016 | Prakash Lab 2016.

Neuropathy Phentoyping Protocols - Hematoxylin and Eosin Staining Resource Report Resource Website |
Eva Feldman | 10.17504/protocols.io.3jsgkne | Diabetic Complications Consortium | Summary:Phenotyping of Rodents for the Presence of Diabetic Neuropathy In man, the development of diabetic neuropathy is dependent on both the degree of glycemic control and the duration of diabetes. Diabetic neuropathy is a progressive disorder, with signs and symptoms that parallel the loss of nerve fibers over time. Consequently, assessments of neuropathy in mice are not performed at one time point, but are characterized at multiple time points during a 6 month period of diabetes. The degree of diabetes is evaluated in 2 ways: tail blood glucose measured following a 6 hour fast and glycated hemoglobin levels. The initial degree of neuropathy is screened using the methods discussed below. Detailed measures of neuropathy are employed when the initial screening instruments indicate a profound or unique phenotypic difference. This document contains protocols used by the DiaComp staff to examine and measure diabetic neuropathy at the whole animal, tissue and cellular levels.Diabetic Complication:Reference: AFIP Laboratory Methods in Histotechnology, 1994, p. 16, 53-55. | University of Michigan - Ann Arbor | https://www.diacomp.org/shared/document.aspx?id=54&docType=Protocol | 1 | 2019 | Eva Feldman 2019.

Modeling ecological drivers in marine viral communities using comparative metagenomics and network analyses Resource Report Resource Website |
Bonnie Hurwitz, Ken Youens-Clark | 10.17504/protocols.io.efgbbjw | VERVE Net, Hurwitz Lab | Long-standing questions in marine viral ecology are centered on understanding how viral assemblages change along gradients in space and time. However, investigating these fundamental ecological questions has been challenging due to incomplete representation of naturally occurring viral diversity in single gene- or morphology-based studies and an inability to identify up to 90% of reads in viral metagenomes (viromes). In this protocol, I describe how to use an annotation- and assembly-free strategy for comparative metagenomics that combines shared k-mer and social network analyses (regression modeling). This robust statistical framework enables visualization of complex sample networks and determination of ecological factors driving community structure. This tutorial describes a protocol to reproduce work from the Pacific Ocean virome comprised of 32 viromes from diverse sites in the Pacific Ocean.

(-)-α-Bisabolol GC sample preparation Resource Report Resource Website |
Dennis Dienst, Oliver Mantovani, Pia Lindberg | 10.17504/protocols.io.xiufkew | CyanoWorld, Metabolomics Protocols & Workflows, Chemistry Method Development Community | This is a quick guide for the preparation of (-)-α-bisabolol samples and external standards in dodecane for GC analysis. This protocol has been established in the Lindberg lab at Ångström laboratory (Uppsala University) for direct analysis of dodecane-based ex-situ extracts from cyanobacterial strains producing (-)-α-bisabolol. The protocol includes the preparation of stock solutions for the internal standard β-caryophyllene (BCP) and the external standard. The preparation of a fresh external standard series is suggested for each sample analysis. The calibration curve is required for quantification of (-)-α-bisabolol in the samples of interest. This protocol is used in combination with the following GC protocol:dx.doi.org/10.17504/protocols.io.kj2cuqe | Department of Chemistry - Microbial Chemistry, Ångström Laboratory, Uppsala, Sweden, Universität Rostock, Germany, Department of Chemistry - Microbial Chemistry, Ångström Laboratory, Uppsala, Sweden | 1 | 2019 | Dennis Dienst, Oliver Mantovani, Pia Lindberg 2019.

Sterivex RNA extraction Resource Report Resource Website |
Ariel Rabines, Rob Lampe, Andrew Allen | 10.17504/protocols.io.bd9ti96n | A.E. Allen Lab | A mostly automated protocol for extraction of total RNA from seawater filtered onto a Sterivex filter (Cat. No. SVGP0150). Reagents come from the Macherey-Nagel NucleoMag RNA kit (Cat. No. 744350). Automated liquid handling is performed on an eppendorf EpMotion 5075t with multi-channel pipettes. This protocol assumes that the Sterivex is sealed with tube sealant on the male end and a male-luer lock plug on the female end. Using this protocol, we routinely extract ~80 samples at a time.The protocol has been modified to increase to an 800 µL starting volume. This normally results in less Lysis Buffer MR1, Binding Buffer MR2, and Reducing Agent TCEP supplied than is needed. Extra reagents can and should be purchased separately. The kit manual can be found here: https://www.mn-net.com/media/pdf/23/c2/23/Instruction-NucleoMag-RNA.pdfAdditional notes from the manufacturer on using the kit with the epMotion can be found here: https://www.mn-net.com/media/pdf/bd/7e/53/AN-NucleoMag-RNA-epMotion5075.pdf .
