Access to low cost retinal imaging devices in low and middle income countries is limited, compromising progress in preventing needless blindness. The Arclight is a recently developed low-cost solar powered direct ophthalmoscope which can be attached to the camera of a smartphone to acquire retinal images and video. However, the acquired data is inherently limited by the optics of direct ophthalmoscopy, resulting in a narrow field of view with associated corneal reflections, limiting its usefulness. In this work we describe the first fully automatic method utilizing videos acquired using the Arclight attached to a mobile phone camera to create wider view, higher quality still images comparable with images obtained using much more expensive and bulky dedicated traditional retinal cameras.Postprin

Nutritional and bioactive composition of Spanish, Valencia, and Virginia type peanut skins

The aims of this study were to determine the proximate and amino acid compositions, mineral content, and fatty acid and proanthocyanidins (PAC) profiles of peanut skins (PS) from three varieties of peanuts. Proximate composition showed that PS had a moisture content from 9.71 to 11.0%, ash content from 2.07 to 2.13%, fat content from 9.59 to 10.2%, protein content from 8.88 to 12.7%, and dietary fiber from 38.8 to 42.8%. The amino acid composition indicated that lysine and phenylalanine, glycine, and glutamine were the predominant amino acids in PS. Mineral content indicated that potassium was the main macro-element in PS. Palmitic, oleic, and linoleic acids were the predominant fatty acids in PS. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) of PAC showed that the predominant masses were typical of (epi)catechin monomers with “A-type” interflavan bonds. Deconvolution of overlapping isotope patterns observed with MALDI-TOF MS indicates that in all PS, 95 % of the PAC oligomers contain one or more A-type bonds. These results indicate that PS may be used as functional ingredients to improve profitability of the peanut industries through the use of a low-value by-product. To the best of our knowledge, this is the first study providing a chemical evaluation and comparison of PS from three varieties of peanuts.Los objetivos de este estudio fueron determinar las composiciones próximas y de aminoácidos, el contenido mineral y los perfiles de ácidos grasos y proantocianidinas (PAC) de pieles de maní (PS) de tres variedades de maní. La composición aproximada mostró que el PS tenía un contenido de humedad de 9,71 a 11,0%, contenido de cenizas de 2,07 a 2,13%, contenido de grasa de 9,59 a 10,2%, contenido de proteínas de 8,88 a 12,7% y fibra dietética de 38,8 a 42,8%. La composición de aminoácidos indicó que la lisina y la fenilalanina, la glicina y la glutamina eran los aminoácidos predominantes en la PS. El contenido mineral indicó que el potasio era el principal macroelemento en la PS. Los ácidos palmítico, oleico y linoleico fueron los ácidos grasos predominantes en la PS. La espectrometría de masas de tiempo de vuelo de ionización / desorción láser asistida por matriz (MALDI-TOF MS) de PAC mostró que las masas predominantes eran típicas de los monómeros de (epi) catequina con enlaces interflavanos "tipo A". La deconvolución de los patrones de isótopos superpuestos observados con MALDI-TOF MS indica que en todos los PS, el 95% de los oligómeros de PAC contienen uno o más enlaces de tipo A. Estos resultados indican que los PS pueden usarse como ingredientes funcionales para mejorar la rentabilidad de las industrias del maní mediante el uso de un subproducto de bajo valor. Hasta donde sabemos, este es el primer estudio que proporciona una evaluación química y una comparación de PS de tres variedades de maní.Universidad Nacional, Costa RicaCentro Nacional de Innovaciones Biotecnológicas, Costa Rica.Universidad de Wisconsin-Madison, Estados Unidos.Soluciones Fitoquímicas Completas, Estados Unidos.Escuela de Químic
