Stability of vacuolar betaxanthin pigments in juices from Moroccan yellow Opuntia ficus indica fruits

2008

Pigment stability of yellow juices prepared from Moroccan cactus pear (Opuntia ficus indica) was determined as a function of temperature and pH. The experiments were carried out at temperatures ranging from 80 to 100 °C with juices at pH 3.5, 5 and 6.5. The degree of pigment retention decreased when the temperature increased. The degradation constant rates were determined for thermal degradation rates of pseudo-first order. The Arrhenius plot obtained for the degradation of betaxanthin from the yellow fruits was not linear. Regardless of the temperature treatment, the lowest degradation was obtained for pH 5. Where some stabilizers were tested for the protection of pigments, the results sho…

Comparative evaluation of bioactive cements on biomimetic remineralization of dentin

2020

Background This study was designed to quantitatively compare the presence of apatite peaks on demineralized dentin to induced bio-mimetically by bioactive commercial materials. Material and methods Dentin slice specimens (n=6) were prepared and demineralized by by17% EDTA for 2 hours. Each disks materials (Theracal, Biodentine, CPP-ACP) were freshly prepared and was maintained in close contact with a demineralized dentin specimen immersed in PBS solution during one week. To evaluation of bioactivity, cements disks (n=6) were prepared from each material and immersed in PBS solution for one week. The bioactivity and remineralization ability was evaluated using FTIR spectroscopy and Scanning E…

Visualizing Human Protein‐Protein Interactions and Subcellular Localizations on Cell Images Through CellMap

2020

Visualizing protein data remains a challenging and stimulating task. Useful and intuitive visualization tools may help advance biomolecular and medical research; unintuitive tools may bar important breakthroughs. This protocol describes two use cases for the CellMap (http://cellmap.protein.properties) web tool. The tool allows researchers to visualize human protein-protein interaction data constrained by protein subcellular localizations. In the simplest form, proteins are visualized on cell images that also show protein-protein interactions (PPIs) through lines (edges) connecting the proteins across the compartments. At a glance, this simultaneously highlights spatial constraints that prot…

During speech perception listeners rely on multimodal input and make use of both auditory and visual information. When presented with speech, for example syllables, the differences in brain responses to distinct stimuli are not, however, caused merely by the acoustic or visual features of the stimuli. The congruency of the auditory and visual information and the familiarity of a syllable, that is, whether it appears in the listener’s native language or not, also modulates brain responses. We investigated how the congruency and familiarity of the presented stimuli affect brain responses to audio-visual (AV) speech in 12 adult Finnish native speakers and 12 adult Chinese native speakers. They…

Nutritional characterization of Butternut squash (Cucurbita moschata D.): Effect of variety (Ariel vs. Pluto) and farming type (conventional vs. orga…

2019

Farming systems and cultivar types are two of the main factors able to affect the nutritional quality of plant foods for human nutrition. Therefore, the aim of this study was to compare the impact of two unexplored variety (namely Ariel and Pluto) and farming type (conventional and organic) on physicochemical parameters, chemical and mineral composition, water- and fat-soluble vitamins, amino acid profile and antioxidant bioactive components of butternut squashes (Cucurbita moschata). In order to achieve this purpose, a multivariate statistical discrimination of the different parameters was carried out using the unsupervised principle component analysis (PCA). The most important differences…

trans-C18: 1 Isomers in Cheeses Enriched in Unsaturated Fatty Acids and Manufactured with Different Milk Fat Globule Sizes

2008

International audience; Increasing the knowledge on dietary fat composition, mainly the minor components, will improve the nutritional value of foods and their labeling. In this study, we examined the trans-octadecenoic acid (C18:1) composition of Emmental cheeses enriched in unsaturated fatty acids (FA) and manufactured with milks produced by cows selected to produce small and large fat globules. The FA composition of the milks was not significantly (P > 0.05) different from the FA composition of the corresponding Emmental cheeses. Increasing the unsaturated FA content of the cheeses using dietary manipulations lead to an increase in the trans-C18:1 and changed their isomeric profiles. In …

Synthesis and influence of fatty acid esters on the foliar penetration of herbicides

1998

Abstract Synthesis of mono-esters of tetraethylene glycol and di-esters of tetraethylene glycol was accomplished from fatty acids and tetraethylene glycol in the absence of solvent and catalyst. Esterification was studied in a batch reactor by using a response surface methodology to evaluate the influence of synthesis variables such as molar substrate ratio of fatty acid relative to tetraethylene glycol (1.39–7.52), temperature (145–167°C), reaction time (0.5–8 h) on the yield of mono- and di-esters of tetraethylene glycol. A multipurpose reactor was developed for the transformation of fatty acids into pure α-monoglycerides. The 1-monoglycerides of heptanoic, undecelenic, oleic, linoleic an…

In the shadow of threatening norms: How students with visual impairment contest and reproduce institutional positions

2020

This article focuses on semi-narrative guided interviews with students with visual impairment (VI) who attend a state-approved special school for students with VI at the time of the interview, although they had different previous experiences in both segregated and inclusive schools. We are conducting a qualitative analysis from the perspective of teenagers concerning how they negotiate institutional ascriptions of (dis)abilities. We have selected interview sequences of two young people: (a) Kai: self-confidence and internalized self-doubt and (b) Felix: between fighting and claiming ableist divides. Our analyses reveal the different ways of how Kai and Felix each contest the ableist divide…

Preferred Outcome Measures Used in Randomized Clinical Trials of Total Knee Replacement Rehabilitation: A Systematic Review.

2020

Objective To determine the most frequently used outcome measures in total knee replacement rehabilitation trials. Literature survey Systematic review of randomized trials searched in five databases: Web of Science, MEDical Literature Analysis and Retrieval System, Physiotherapy Evidence Database, Scopus, and Cochrane Library. Methodology Trials were included if participants underwent total knee replacement rehabilitation and outcome measures were used to assess rehabilitation outcomes. A descriptive synthesis determined the frequency of using outcome measures and preferred assessment time points. Outcomes were classified into eight categories: patient- and clinician-reported function, perfo…

Vibroacoustic treatment for chronic pain and mood disorders in a specialized healthcare setting

2017

Much of what we know about vibroacoustic treatment and its efficacy has been published in case reports. Recent clinical trials have increased awareness and understanding of this treatment for people with Parkinson’s disease or Fibromyalgia Syndrome. There are no standardized protocols for using vibroacoustic treatment although research has focused on using 40Hz. The rehabilitation unit of [blinded] Central Hospital in [blinded] has used vibroacoustic treatment for more than two decades as part of specialized healthcare in the [blinded] healthcare district. Patient responses have been recorded using Visual Analog Scales showing positive outcomes on several measures including pain and mood. T…
