Updated Bottom Up Solution for Triacylglycerols

This Microsoft Excel workbook (2.712 Mb) contains spreadsheets that implement the Updated Bottom Up Solution for Triacylglycerols that allows Critical Ratios that provide structural information from mass spectrometry to be used to reconstitute the original mass spectra from which they came. It contains spreadsheets that use the non-nested equations (Critical Limits explicitly shown), as well as spreadsheets that used the nested equations (Case determinations made with Critical Limits not explicitly shown).

Quantification of TAGs by LC-MS

This Microsoft Excel workbook contains spreadsheets for calculating response-factor normalized triacylglycerol (TAG) compositions from response factors derived from GC-FID of fatty acid methyl esters (FAME). This workbook (1.160 Mb) reads the output from a ThermoScientific XCalibur Quan Browser •Excel Short Report• (In XCalibur: File • Export data to Excel • Export Short Excel report), and requires input of the FA composition determined by GC-FID (manually entered or read from Excel spreadsheet [provided upon request]).

Isotope-corrected Critical Ratio calculations

This Microsoft Excel workbook (168.259 Mb) calculates Critical Ratios for triacylglycerols based on manually entered mass spectra, with isotope correction by isotope patterns calculated at www.ChemCalc.org. Average mass spectra across integrated peaks are manually entered according to the instructions in the Supplementary Material to the publication 'The Updated Bottom Up Solution for Mass Spectrometry of Soybean Oil in a Dietary Supplement Gelcap".

Delta Food Outlets Study

The Delta Food Outlets Study was an observational study designed to assess the nutritional environments of 5 towns located in the Lower Mississippi Delta region of Mississippi. It was an ancillary study to the Delta Healthy Sprouts Project and therefore included towns in which Delta Healthy Sprouts participants resided and that contained at least one convenience (corner) store, grocery store, or gas station. Data were collected via electronic surveys between March 2016 and September 2018 using the Nutrition Environment Measures Survey (NEMS) tools. Survey scores for the NEMS Corner Store, NEMS Grocery Store, and NEMS Restaurant were computed using modified scoring algorithms provided for these tools via SAS software programming. Because the towns were not randomly selected and the sample sizes are relatively small, the data may not be generalizable to all rural towns in the Lower Mississippi Delta region of Mississippi.

FoodData Central

Several USDA food composition databases, including the Food and Nutrient Database for Dietary Studies (FNDDS), Standard Reference (SR) Legacy, and the USDA Branded Food Products Database, have transitioned to FoodData Central, a new and harmonized USDA food and nutrient data system. FoodData Central will also include expanded nutrient content information never before available, as well as links to diverse data sources that offer related agricultural, food, health, dietary supplement, and other information.

Data from: Assessment of town and park characteristics related to physical activity in the Lower Mississippi Delta

The Delta Neighborhood Physical Activity Study was an observational study designed to assess characteristics of neighborhood built environments associated with physical activity. It was an ancillary study to the Delta Healthy Sprouts Project and therefore included towns and neighborhoods in which Delta Healthy Sprouts participants resided. The 12 towns were located in the Lower Mississippi Delta region of Mississippi. Data were collected via electronic surveys between August 2016 and September 2017 using the Rural Active Living Assessment (RALA) tools and the Community Park Audit Tool (CPAT). Scale scores for the RALA Programs and Policies Assessment and the Town-Wide Assessment were computed using the scoring algorithms provided for these tools via SAS software programming.

Data from: Genome Sequence of the Thermotolerant Foodborne Pathogen Salmonella enterica Serovar Senftenberg ATCC 43845 and Phylogenetic Analysis of Loci Encoding Increased Protein Quality Control Mechanisms

Salmonella enterica subsp. enterica bacteria are important foodborne pathogens with major economic impact. Some isolates exhibit increased heat tolerance, a concern for food safety. Analysis of a finished-quality genome sequence of an isolate commonly used in heat resistance studies, S. enterica subsp. enterica serovar Senftenberg…
