(Sociedad Chilena de Quimica, 2016)In this study, a new method for determination of triclabendazole (TCB) as its main metabolites, triclabendazole sulfoxide (TCB-SO) and triclabendazole sulfone (TCB-SO2) in animal plasma was developed. TCB is widely used ...
-
(American Physiological Society, 2013)© 2013 The Authors. Fetal brain hypoxic injury remains a concern in high-risk delivery. There is significant clinical interest in agents that may diminish neuronal damage during birth asphyxia, such as in allopurinol, an ...
-
(Elsevier B.V., 2017)© 2016 Elsevier B.V. Montmorillonite (MMT) clays were modified by the intercalation into their galleries of ionic liquids (IL) based on imidazolium quaternary ammonium salts. This new eco-materials exhibited good features ...

(Elsevier B.V., 2017)© 2016 Elsevier B.V.This paper presents a method for the determination of imidacloprid in honeybees based on the measurement of excitation-emission spectra of photo-induced fluorescence (PIF-EEMs) associated to unfolded ...
-
(1988)‘Marraqueta’ and ‘Hallulla’ breads, widely consumed in Chile, were enriched with 6, 9 and 12% full‐fat sweet lupin flour (FFLF) containing a small amount of alkaloids (0.025%) and 42.8% protein. Physical characteristics ...
-
(Elsevier Inc., 2016)© 2016 Elsevier Inc. This study aimed to investigate the expression profiles of growth differentiation factor 9 (GDF-9) and bone morphogenetic protein 15 (BMP-15) mRNA in canine oocytes and follicular cells throughout ...
-
(Academic Press Inc., 2017)© 2016 Elsevier Inc.DNA staining in gels has historically been carried out using silver staining and fluorescent dyes like ethidium bromide and SYBR Green I (SGI). Using fluorescent dyes allows recovery of the analyte, but ...
