Alteration of sphingolipids in biofluids: Implications for neurodegenerative Diseases
(Multidisciplinary Digital Publishing Institute, 2019-07-21)
Sphingolipids (SL) modulate several cellular processes including cell death, proliferation and autophagy. The conversion of sphingomyelin (SM) to ceramide and the balance between ceramide and sphingosine-1-phosphate (S1P), ...
Metabolic profiling of biofluids in fish for identifying biomarkers of exposure and effects for assessing aquatic pollution
(Elsevier, 2020)
The development of OMICs technologies has enabled the possibility of assessing a massive amount of data from the transcriptome, proteome, and/or metabolome, in response to the exposure to environmental pollutants. These ...
Green synthesis of fluorescent carbon dots for determination of glucose in biofluids using a paper platform
(2019-08-15)
In this paper, we describe a novel carbon dot (CD)synthesized from citric acid and tyramine using a one-step microwave heating route. Under UV irradiation, the CD displayed blue emission that was quenched in the presence ...
Simultaneous analysis of five antidepressant drugs using direct injection of biofluids in a capillary restricted-access media-liquid chromatography-tandem mass spectrometry system
(ELSEVIER SCIENCE BV, 2008)
Direct analysis, with minimal sample pretreatment, of antidepressant drugs, fluoxetine, imipramine, desipramine, amitriptyline, and nortriptyline in biofluids was developed with a total run time of 8 min. The setup consists ...
Analysis of endocannabinoids in plasma samples by biocompatible solid-phase microextraction devices coupled to mass spectrometry
(Elsevier Science, 2019-09)
Anandamide (AEA) and 2-arachidonoyl glycerol (2-AG) represent two of the most important endocannabinoids (ECs) investigated in neurobiology as therapeutic targets for several mental disorders. However, the determination ...
Development and optimization of a flexible enzyme-based platform for the colorimetric quantification of metabolic disease-related salivary biomarkers
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-04)
Early detection aims at timely treatment to improve patient's fate. To fulfill this, the identification and validation of appropriate biomarkers, as well as the development of rapid, simple, sensitive and low-cost methodologies ...
Hemodynamic analysis based on biofluid models and MRI velocity measurements
(Universidad de Chile, 2019)
For the diagnosis, treatment planning and post-surgical monitoring of cardiovascular disease
(CVD), hemodynamic markers have proven to be of great utility. However, non-invasive assessment of the hemodynamics of a patient ...
Direct Coupling of Dispersive Extractions with Magnetic Particles to Mass Spectrometry via Microfluidic Open Interface
(American Chemical Society, 2019-04)
Microextraction coupled to mass spectrometry (MS) has great potential in analytical chemistry laboratories operating in a variety of fields. Indeed, microextraction methods directly coupled to MS can be of large value given ...
Fabrication, 3d finite element analysis and characterization of an optical passive microsensor
(Asociación Argentina de Mecánica Computacional, 2013-11-19)
In this work we present the 3D Finite Element Analysis (FEA) of an optical passive microsensor for measuring pressure in biofluids and the simulation of the required characterization setup. Previously, we reported the ...
