|Analysis of Terpenes Using Gas Chromatography with Vacuum Ultraviolet |
Changling Qiu, Jonathan Smuts, Phillip Walsh, and Kevin A. Schug
The VUV absorption spectra for different terpenes were distinctive and differentiable. GC-VUV demonstrated the capabilities for qualitative and quantitative analysis of terpenes in turpertine mixtures. Chromatographic coeluting signals can be deconvolved by the VUV data analysis software.
|Mobility of Aeroallergens in Home: Effect of Location of Air Sampling and Implication for Evaluation of Patient Exposure|
Julian Gordon1, Paul Detjen, Andrea Wachter & Prasanthi Gandhi1
The Inspirotec sampler permitted the easy testing of multiple locations within a household. Air sampling simultaneously at 12 locations by other technologies would have been technically challenging. These were run by an untrained operator.
|Lutjanus jocu (Dog snapper) as a bio-indicator of emerging contaminants and changes in environmental condition.|
M. Sánchez-García1, S. J. Zottoli2 & L.Roberson-Murillo1
Our research assesses the use of Lutjanus jocu as a bioindicator of changes in environmental condition and water contaminated with toxic substances in estuarine ecosystems.
|Selective Debenzylation of N-Benzyloxypyrazinones in Flow|
Anh Hung MAI - Cedrick VERYSER - Wim DE BORGGRAEVE
Selective and reproducible debenzylation of benzyloxypyrazinones by using catalytic transfer hydrogenation in flow chemistry to yield N-hydroxypyrazinones. The flow methodology enabled us to avoid overreduction of the compounds to pyrazin-2(1H)-ones.
|Differences in the Neurophysiology of Infants with Down Syndrome May Predict Protective/Risk Markers for Subsequent Alzheimer’s Disease|
Esha Massand1,2, Hana D’Souza1,2, George Ball1,2, Maria Eriksson1, Charlotte Dennison1, Joanna Ball1 & Annette Karmiloff-Smith1,2
Our work set out to understand early individual differences in memory abilities of infants with DS that may be predictive of subsequent cognitive phenotypes of AD.
|Determination of C2-C12 Aldehydes in Water by SPME Arrow On-Fiber Derivatization and GC/MS|
Peter Egli, Beat Schilling, Guenter Boehm, Kai Schueler
A method applying SPME Arrow extraction and on-fiber derivatization for the quantitation of C2-C12 aldehydes in water by GC/MS is described.
|Assessing Diversity in Cassava through the Application of Metabolomics|
Margit Drapala, Elisabete Carvalhoa, Laura Perez-Fonsa, Elliott Pricea, L. Augusto Becerra Lopez-Lavalleb, Paul D. Frasera
In the present study metabolomic platforms have been established for Cassava and used to assess the biodiversity present in Cassava germplasm collections and elucidate underlying biochemical mechanisms associated with traits of interest.
|Addressing False Positive Variants Arising from Pseudogenes|
Risha Govind1,2, Sam Wilkinson1,3, Nicola Whiffin1,2, Shibu John1,2, Rachel J. Buchan1,2, Elizabeth Edwards1,2, Deborah J. Morris-Rosendahl1,3, James S. Ware1,2, P.J. Barton1,2, Stuart A. Cook1,2
Clinical genetic testing has been transformed in recent years by the introduction of Next-Generation Sequencing (NGS).
|Metabolomic profile of multiple sclerosis patients by means of 1H-NMR analysis|
Federica Murgia1, Lorena Lorefice 2 ,Eleonora Cocco2, Luigi Barberini2, Simone Poddighe1, Maria Rita Murru2, Raffaele Murru2, Jessica Frau2, MD Giuseppe Fenu2, MD, Giancarlo Coghe2, Francesco Del Carratore1, Luigi Atzori1, Maria Giovanna Marrosu3
Multiple sclerosis (MS) is a chronic disease characterized by a high level of heterogeneity. Metabolomics is an “-omics” approach with the potential to discover new biomarkers.
