Understanding and evaluation of the fundamental cause and effect relationships with the liquid to be measured will lead to a volume determination that most closely matches the "true" volume at the referenced "standard" pressure and temperature.

With the continued progression of the "omics" era, bioinformatics, a discipline concerned with the curation and interpretation of biological data by computational means, has seen widespread integration across life sciences. However, despite becoming very data rich disciplines in the past number of years, the role of bioinformatics in food and nutritional sciences is less appreciated. In this review, we present the current state of bioinformatics in food and nutritional sciences and offer exemplar templates from other fields where bioinformatic analyses have become an integral feature. Additionally, we propose the concept of a wiki-like food database that could greatly advance the capabilities of bioinformatics in food and nutritional research. © 2013 Elsevier Ltd. Source

Objective: Previous studies have evaluated the cervical range of axial rotation during simulated driving conditions. The goals of this pilot study were to describe cervical spine rotation during in-car driving and determine the percentage of time outside neutral neck rotation and peak cervical axial rotation angles that the subjects adopted during various driving conditions. Methods: Subjects drove around a specified route through the city of Guelph, Ontario, which included residential, thruway, and highway driving; additional minor driving tasks, such as lane changes, were also included. The cervical range of motion was measured continuously throughout the drive using an electromagnetic sensor; we also used videotape to document the specific driving tasks. Results: The subjects spent 87.0 percent (SD = 8.8) of time with their cervical spine in the neutral axial rotation position (±15 degrees). The percentage of time that the subjects spent outside of the neutral range of cervical axial rotation depended upon the driving section (including residential, thruway, and highway), and driving task being performed (starts, stops, and lane changes). The subjects spent a significantly greater proportion of time with their necks rotated beyond neutral during residential driving compared to thruway and highway driving (19.1% SD = 8.3 vs. 10.7% SD = 9.5 and 9.3% SD = 8.7, respectively; <.001). During driving, the peak angles of cervical axial rotation were an average of 35.7 degrees (SD = 14.2) left and 42.5 degrees (SD = 18.0) right. Conclusions: We observed a large degree of variability in cervical axial rotation during driving. We observed that most of the driving tasks related to stopping had increased proportion of time out of neutral rotation. Also, right-hand lane changes increased time out of neutral rotation more than left-hand lane changes. Drivers routinely adopt nonneutral head positions (on average 13% of the time); this is likely not enough to lead to injury. © 2011 Taylor & Francis Group, LLC. Source

Small extracellular vesicles are released from both healthy and disease cells to facilitate cellular communication. They have a wide variety of names including exosomes, microvesicles and microparticles. Depending on their size, very small extracellular vesicles originating from the endocytic pathway have been called exosomes and in some cases nanovesicles. Collectively, extracellular vesicles are important mediators of a wide variety of functions including immune cell development and homeostasis. Encapsulated in the extracellular vesicles are proteins and nucleic acids including mRNA and microRNA molecules. MicroRNAs are small, non-coding RNA molecules implicated in the post-transcriptional control of gene expression that have emerged as important regulatory molecules and are involved in disease pathogenesis including cancer. In some diseases, not only does the quantity and the subpopulations of extracellular vesicles change in the peripheral blood but also microRNAs. Here, we described the analysis of peripheral blood extracellular vesicles by flow cytometry and the RNA extraction from extracellular vesicles isolated from the plasma or serum to profile microRNA expression. © Springer Science+Business Media New York 2013.

Phytophthora cinnamomi isolates from geographically diverse oak forest soils in the Mid-Atlantic regions were studied to determine the extent of genotypic, phenotypic, and pathogenic variation. Four microsatellite loci were targeted for genetic analysis. Phenotypic characteristics measured included sexual and asexual spore dimensions and colony growth rate and morphology. Red oak (Quercus rubra) logs were inoculated with selected isolates to determine relative pathogenicity. Microsatellite analysis showed that the genetic variability of P. cinnamomi isolates was low, with two predominant microsatellite fingerprint groups (MFG). Isolates in MFG1 (48% of the total isolates examined) were characterized by DNA fragment lengths of 120 and 122 bp at locus d39, 169 and 170 bp at locus e16, and 254 and 255 bp at locus g13. MFG2 isolates were characterized by marker sizes of 122 and 124 bp at locus d39, 161 and 163 bp at locus e16, and 247 and 248 bp at locus g13. Asexual and sexual spore dimensions varied greatly among isolates but were similar to previously published descriptions. Phenotypic differences were most pronounced when data were grouped by MFG; the most significant were colony morphology and growth rate. Neither characteristic was a reliable predictor of isolate genotype. Differences in growth rates of MFGs were observed, with MFG1 being less tolerant at higher incubation temperatures. No variation in pathogenicity was observed on red oak logs. The low level of phenotypic and genotypic variation of P. cinnamomi suggest that other factors such as climate might play a more important role in its northern distribution and the diseases it causes. © 2012 The American Phytopathological Society.
