Sensing immobilized molecules of streptavidin on a silicon surface by maldi-tof mass spectrometry and fluorescence microscopy
(2014)
A hydrogen-terminated Si (111) surface was modified to form an aminoterminated monolayer for immobilization of streptavidin. Cleavage of an N-(ω-
undecylenyl)-phthalimide covered surface using hidrazine yields an amino ...
Rapid Determination of Parabens in Water Samples by Ultra-high Performance Liquid Chromatography Coupled to Time of Flight Mass Spectrometry
(Japan Soc Analytical Chemistry, 2020)
An analytical methodology has been developed and validated for the purpose of identifying and quantifying four parabens (methylparaben, ethylparaben, propylparaben and n-butylparaben) in water samples. The combination of ...
Peritonitis fúngica por Rhodotorula mucilaginosa en una paciente en diálisis peritoneal automatizada. Revisión de la literatura
(Soc Chilena Infectología, 2016)
Fungal peritonitis is a major complication of peritoneal dialysis associated with high mortality. Most survivors have a high rate of abandonment of peritoneal dialysis. We report a case of fungal peritonitis due to an ...
Laboratory exposure to Coccidioides: lessons learnt in a non-endemic country
(W.B. Saunders Ltd, 2019)
Coccidioides is a primary pathogenic fungus, which infects humans through highly infectious arthroconidia, causing substantial morbidity including life-threatening disseminated infections. Due to the low infectious dose, ...
An intramolecular O-N migration reaction on gold surfaces: Toward the preparation of well-defined amyloid surfaces
(2009)
Amyloids are a family of self-aggregating proteins implicated in various central nervous system disorders, including Alzheimer's disease (AD). It is thought that prefibrillar soluble forms of amyloid peptides, including ...
Liquid chromatography–time-of-flight high-resolution mass spectrometry study and determination of the dansylated products of estrogens and their hydroxylated metabolites in water and wastewater
(Springer Verlag, 2018)
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. A method combining liquid chromatography with a dual-probe ultraspray electrospray ionization (ESI) source and time-of-flight high-resolution mass spectrometry ...
Acylglycerol synthesis including EPA and DHA from rainbow trout (Oncorhynchus mykiss) belly flap oil and caprylic acid catalyzed by Thermomyces lanuginosus lipase under supercritical carbon dioxide
(Springer, 2021)
Supercritical carbon dioxide (SCCO2) was studied as a medium for the esterification of eicosapentaenoic acid (n-3 C20:5, EPA) or docosahexaenoic acid (n-3 C22:6, DHA) and caprylic acid (C8:0, CA) in structured triacylglycerols ...
Ultra-high-performance liquid chromatography-Time-of-flight high resolution mass spectrometry to quantify acidic drugs in wastewater
(Elsevier, 2015)
A novel analytical approach involving an improved rotating-disk sorptive extraction (ROSE) procedure and ultra-high-performance liquid chromatography (UHPLC) coupled to an ultraspray electrospray ionization source (UESI) ...
Stereo Time-of-Flight with Constructive Interference
(IEEE, 2014)
This paper describes a novel method to acquire depth images using a pair of ToF (Time-of-Flight) cameras. As opposed to
approaches that filter, calibrate or do 3D reconstructions posterior to the image acquisition, we ...
Initial experience in Chile with stent implantation in the right ventricle outflow tract in high-risk patients with tetralogy of Fallot
(Springer, 2020)
Tetralogy of Fallot (ToF) treatment is difficult in patients with surgical risk factors or unfavorable anatomy. Stent implantation in the right ventricular outflow tract (RVOT) is an option for these patients. We report ...
