In the search for a healthy indoor climate, chemical cleaning agents are replaced by bacillus strains to create an ecosystem in which these harmless bacteria clean surfaces consuming organic molecules dust and dirt. To optimise ecosystems, it is important monitor bacterial growth activity, but reference methods time involve serious delay. Therefore, potential of fluorescence spectroscopy monito...

BACKGROUND The consumption of high levels of industrial trans fatty acids (TFA) has been related to cardiovascular disease, diabetes and sudden cardiac death but the causal mechanisms are not well known. In this study, NMR and LC-MS untargeted metabolomics has been used as an approach to explore the impact of TFA intake on plasma metabolites. METHODOLOGY/PRINCIPAL FINDINGS In a double-blinded...

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) despite being increasingly used as a method for microbial identification, still present limitations in which concerns the differentiation of closely related species. Bacillus pumillus and Bacillus safensis, are species of biotechnological and pharmaceutical significance, difficult to differentiate by con...

• ATR FTIR spectra of urine sediment derived from patients with normal, abnormal and bladder cancer cells in cytology were classified partial least squares-discriminant analysis (PLS-DA). Cancer samples contain higher lipids, proteins nucleic acids levels than normal group on contrary to sugar moieties. Correlation histological assessment confirmed the proper spectroscopic assignment groups wha...

Coral reefs are suffering unprecedented declines in health state on a global scale. Some have suggested that human assisted evolution or gene flow may now be necessary to effectively restore and pre-condition them for future climate change. An understanding of the key metabolic processes corals, including under stressed conditions, would greatly facilitate effective application such interventio...

Numerous statistical machine learning methods suitable for application to highly correlated features, as those that exist spectral data, could potentially improve prediction performance over the commonly used partial least squares approach. Milk samples from 622 individual cows with known detailed protein composition and technological trait data accompanied by mid-infrared spectra were availabl...

Near-infrared (NIR) diffuse reflectance has been extensively and successfully applied on quality assurance for fruits, vegetables, and food products. This study is principally aimed to extract the primary wavelengths related to the prediction of glucose and sucrose for potato tubers (of Frito Lay 1879 (FL), a chipping cultivar, and Russet Norkotah (RN), a table use cultivar, and investigating t...

The development and deployment of sensors for undersea cabled observatories is presently biased toward the measurement of habitat variables, while sensor technologies for biological community characterization through species identification and individual counting are less common. The VENUS cabled multisensory network (Vancouver Island, Canada) deploys seafloor camera systems at several sites. O...

Intestinal epithelial cells exist within a complex environment that affects how they interpret and respond to stimuli. We have applied a multi-scale in vivo systems approach to understand how intestinal immune cells communicate with epithelial cells to regulate responses to inflammatory signals. Multivariate modeling analysis of a large dataset composed of phospho-signals, cytokines, and immune...
