Es necesario investigar drogas naturales nuevas que aporten principios farmacológicos activos para ser utilizadas como una alternativa terapéutica. Por este motivo nos propusimos estudiar a Ficus insipida, cuyo látex ha sido usado como antihelmíntico durante muchos años en la amazonía, pero se investigó solo superficialmente su efecto anticoagulante in vitro. Objetivo: Comprobar el efecto anticoagulante in vitro y determinar la vía de la coagulación sobre la que actúa el látex de Ficus insípida. Material y métodos: Se obtuvo el látex de Ficus insipida y se prepararon diferentes concentraciones del mismo. Se obtuvieron muestras de sangre venosa periférica de 5 donantes voluntarios, anticoagulándolas con citrato de sodio. Luego, éstas se mezclaron con las diluciones del l&...

En este trabajo informamos sobre 14 casos de luxación acromioclavicular de los grados Ill, IV y V, en pacientes activos. Los casos fueron tratados quirúrgicamente con extirpación de 1 .5 a 2.5 cm de clavícula distal; fijación por tres meses con un tornillo maleolar de clavícula a base de apocoracoides, reparación de ligamentos coracoclaviculares; refuerzo con ligamento coracoacromial, reparación imbricada de los músculos deltoides y trapecio y fascia deltopectoral. El seguimiento postoperatorio fue de uno a tres araos con buen resultado funcional.

Quinoa is an Andean crop that stands out as a high-quality protein-rich and gluten-free food. However, its increasing popularity exposes quinoa products to the potential risk of adulteration with cheaper cereals. Consequently, there is a need for novel methodologies to accurately characterize the composition of quinoa, which is influenced not only by the variety type but also by the farming and processing conditions. In this study, we present a rapid and straightforward method based on matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) to generate global fingerprints of quinoa proteins from white quinoa varieties, which were cultivated under conventional and organic farming and processed through boiling and extrusion. The mass spectra of the different protein extracts were processed using the MALDIquant software (version 1.19.3), detecting 49 prot...

The oil of debittered and dehulled grains from two Andean lupins (Lupinus mutabilis) from Peru, Andenes and Común, was extracted by expeller press. The extraction yield and the proximal composition of both varieties were assessed. The oil and the cake, as well as the defatted flour from the variety with the highest extraction yield, were characterised for physico-chemical properties, total polyphenol content and antioxidant capacity. The oil shelf-life at 25 °C was extrapolated by Rancimat test. Andenes presented an oil yield of 22.1% (vs. 18.4% of Común), CIELAB colour coordinates of L* = 36.5, a* = 2.2, b* = 20, refractive index and density at 25 ºC of 1.469 and 0.903 g/mL, acid number of 3.2 mg KOH/g, free fatty acids content of 1.6%, peroxide number of 2.7 meqO2/kg, p-anisidine number of 1.3, unsaponificable content of 58%, total antioxidant capacity 21.4 µmol TE/g and total pol...
