Purpose: To evaluate dry eye (DE) and subjective visual display terminal (VDT)-related symptoms in university students who moved their classes online due to the COVID-19 pandemic.Methods: Cross-sectional study of students who were taking online classes. In May 2020, the participants completed a Dry Eye Questionnaire (DEQ-5) and a self-report survey, which included demographics, medical history, information on the use of VDT and presence of VDT-related symptoms. Participants were classified as ha...

Abstract The sensorial quality of wine grapes largely depends on the phenolic composition. Malbec, Tempranillo, Sangiovese, Petit Verdot, Cabernet Franc and Carmenere are emblematic Vitis vinifera red grape varieties for wine-producing valleys around the world. This study aimed to characterize the phenolic composition (total phenols, tannins and anthocyanins, size-based proanthocyanidin fractions, anthocyanidin conjugates and low molecular weight phenolics) of grape skins from those alien variet...

Abstract In wine, polyphenols are closely associated with astringency, bitterness, color and aroma. Some of these sensory parameters have been reported to be dynamically perceived during wine tasting. In this study, time-dependent sensory methodologies (Temporal Dominance of Sensations or TDS, and Temporal-Check-All-That-Apply or TCATA) were used to characterize wines made from six grape varieties. Sensory analysis was contrasted against the phenolic composition of wines. Temporal sensory method...

Abstract Commercial enological tannins (CETs) are wine additives that are mostly aimed at modulating astringency. This study aims at comparing the effects of eleven CETs (supplied by 4 companies) extracted either from grapes (n = 2) or oak wood (n = 9) on the salivary protein fraction and on the astringency they provoke. Phenolic compounds were characterized by spectrophotometry and HPLC methods. Interaction of CETs with the salivary protein was assessed by diffusion on cellulose membranes and p...

This study characterized the flavonoid and nonflavonoid phenolic composition of Carmenere and Cabernet Sauvignon wines that were in contact with barrels, chips, and staves during a 12?month aging period. The wines were evaluated by spectrophotometric (for total phenols, anthocyanins and tannins, colorant intensity, hue, CIELab parameters, and fractionation into mono-, oligo-, and polymers of proanthocyanidins) and high-performance liquid chromatography diode array detection analyses (for ellagit...

Abstract The effect of the addition of different commercial enological tannins (CETs) on the characteristics of Carmenere red wine was evaluated. Initially, chemical characterization of eleven CETs was performed using spectrophotometric and HPLC-DAD techniques. Then, the effects of six CETs on the properties of a Carmenere wine during bottle storage (90 days) were evaluated for up to 90 days. Four CETs from wood exhibited highly variable phenolic compositions and the highest values of hydrolyzab...

Abstract Objective To determine prevalence of Demodex spp. and infestation index (II) by the parasite among patients of different ages with blepharitis and to assess association with occurrence of cylindrical dandruff (CC). Materials and methods Prospective study including patients diagnosed with posterior blepharitis between 2013 and 2015, without previous acaricide treatment, was conducted by Fundacion Oftalmologica Los Andes (Chile). Four eyelashes were randomly extracted from each eyelid for...
