Steroidal glycosides from the Vietnamese cultivar Cordyline fruticosa “Fairchild red”
2021
Abstract A phytochemical study of Cordyline fruticosa “Fairchild red” (Asparagaceae) from Vietnam, led to the isolation of fourteen steroidal glycosides, including twelve previously undescribed along with two known ones. Ten compounds were obtained by successive solid/liquid chromatographic methods from an aqueous-ethanolic extract of the roots, and four from the aerial parts. Their structures were elucidated mainly by spectroscopic analysis 2D NMR and mass spectroscopy (ESI-MS), as spirostanol glycosides, 5α-spirost-25(27)-ene-1β,3β,4α-triol 1-O-β-D-fucopyranoside, 5α-spirost-(25)27-ene-1β,3β,4α-triol 1-O-β-D-xylopyranoside, 5α-spirost-(25)27-ene-1β,3β,4α-triol 1-O-α-L-rhamnopyranosyl-(1 →…
Coronary Slow Flow in a Patient with Myocarditis
2016
A young patient presented with dyspnea and high troponin. Coronary angiography excluded a diagnosis of CAD, but was diagnostic for the presence of coronary slow flow. Thermodilution showed increased resting resistances in the presence of hypernormal CFR.
Defining Kawasaki disease and pediatric inflammatory multisystem syndrome-temporally associated to SARS-CoV-2 infection during SARS-CoV-2 epidemic in…
2021
Abstract Background There is mounting evidence on the existence of a Pediatric Inflammatory Multisystem Syndrome-temporally associated to SARS-CoV-2 infection (PIMS-TS), sharing similarities with Kawasaki Disease (KD). The main outcome of the study were to better characterize the clinical features and the treatment response of PIMS-TS and to explore its relationship with KD determining whether KD and PIMS are two distinct entities. Methods The Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD (Kawasaki Disease Group – KDG) or KD-like (Kawacovid Group - KCG) disease between February 1st 2020, and May 31st 2020. Demographic, clini…
Diagnostic accuracy of adding copeptin to cardiac troponin for non-ST-elevation myocardial infarction: A systematic review and meta-analysis.
2018
Introduction This study aimed to determine the diagnostic accuracy of adding copeptin to cardiac troponin (cTn) on admission to the emergency department (ED) for non-ST elevation myocardial infarction (NSTEMI) compared to cTn alone. Materials and methods A literature search of MEDLINE, EMBASE, and the Cochrane Library was performed (search date: April 13, 2018). Primary studies were included if they accurately reported on patients with symptoms suggestive of acute myocardial infarction and measured both cTn alone and cTn with copeptin upon admission to the ED. The patients with evidence of ST elevation myocardial infarction were excluded. To assess the risk of bias for the included studies,…
Research on children's lexical availability: applications for SFL teaching
2022
Esta investigación presenta la aportación que la disponibilidad léxica tiene en el marco de la enseñanza de Español como Lengua Extranjera y el ámbito infantil. Para poder desarrollar esta tarea se ha realizado una revisión bibliográfica sistemática que presenta a aquellos trabajos publicados sobre léxico disponible. A partir de los resultados obtenidos se ha observado una baja incidencia de investigaciones sobre ELE con población escolar (hasta 12 años), en comparación con corpus adultos. En segundo lugar, también se han localizado, a parte de los dieciséis centros de interés tradicionales, treinta áreas complementarias o novedosas que coinciden con las clasificaciones desarrolladas por el…
Phytotoponymy and Synphytotoponymy in Western Granada Province (Andalusia, Spain)
2009
En el marco de la investigación etnobotánica desarrollada en el poniente granadino, se ha realizado un estudio sobre la toponimia de la comarca con atención a los apelativos de origen vegetal (fitotopónimos y sinfitotopónimos). La información —obtenida de la Gerencia Territorial del Catastro de Granada, de la Junta de Andalucía y de nuestro trabajo de campo— se ha incluido en una base de datos con el programa Microsoft Excell®. Un total de 98 especies vegetales se encuentran representadas en la toponimia local, dando nombre a 593 lugares del territorio. Se aportan comentarios sobre el significado ecológico, paleofitogeográfico y etnobotánico de las especies reflejadas en la toponimia.
Microwave-assisted saponification of animal greases for cholesterol determination
1998
Abstract An alternative method for the hydrolysis of cholesterol esters in animal grease samples has been developed. The method consists of the microwave-assisted treatment of 4 g of animal fat or oil with 40 ml of an ethanolic KOH solution inside a 115 ml closed reactor in which samples were irradiated for 2.5 min at 50% power level of an exit power of 700 W. After extraction with petroleum ether and dissolution of the unsaponifiables in toluene, total cholesterol was determined spectrophotometrically by using p-anisidine as a test reagent of the enzymatic reaction of cholesterol through a bienzymic reactor in which cholesterol oxidase and horseradish peroxidase were noncovalently immobili…
Simultaneous quantification of serum phytosterols and cholesterol precursors using a simple gas chromatographic method
2012
Determination of the main phytosterols (Ps, β-sitosterol and campesterol) and cholesterol precursors (desmosterol and lathosterol) in human serum using a simple GC-FID method has been validated. Direct saponification, without lipid extraction, sterols extraction, and further derivatization was applied to samples prior to GC analysis. To evaluate the method, a pool of serum samples from eight healthy women was used. Good linearity (r>0.99) was found in the assay range: β-sitosterol (0.99–17.82 µg/mL), campesterol (0.14–10.8 µg/mL), desmosterol (0.17–2.6 µg/mL), and lathosterol (0.6–5.97 µg/mL). Limits of detection (ng/mL) were: 86 (β-sitosterol), 42 (campesterol), 4 (desmosterol), and 44 (la…
Flow injection determination of free and total cholesterol in animal greases using enzymes in non-aqueous media
1998
A non-covalently coimmobilized bienzymic reactor of horseradish peroxidase (HRP) and cholesterol oxidase (COD), operating in a continuous organic flowing stream of 1 × 10–3 M p-anisidine in buffer-saturated (pH 7.0) toluene, has been employed for cholesterol determination in animal greases, such as pig, beef, and chicken fat, and codfish liver oil. The method provides a good linear relationship up to 1.8 × 10–3 M cholesterol and average recoveries of 99.5%, a high sensitivity, with a detection limit of 1 × 10–6 M of cholesterol and a good precision (an interday RSD of 1.8% for the determination of total cholesterol in a codfish oil sample). The method permits the direct spectrophotometric d…
