| 3 | Addition of phenolic compounds to bread: antioxidant benefits and impact on food structure and sensory characteristics显示文摘The use of flours or phenolic extracts obtained from non-traditional sources or agri-food industry by-products has been a strategy used to formulate new bakery products with characteristics of a functional food.However,phenolic compounds present great structural diversity,as well as the ability to interact in a complex way with the macromolecules that constitute the bread matrix.Therefore,the addition of these flours,extracts or pure compounds produces various effects on the microstructure of bread,and several of its sensory properties.This is mainly due to interactions between phenolic compounds and gluten proteins.The objective of this review is to analyze some of the most recent published works on the addition of phenolic compounds in wheat bread to identify the type of positive and negative effects that have been observed and how they can be related to the physicochemical interactions between phenolic compounds and the macromolecules that constitute the food matrix,mainly gluten.The effect of monomeric and polymeric phenolic compounds on the strength of these interactions and on the properties of dough and bread are discussed. | Yesica A.Czajkowska–González Emilio Alvarez–Parrilla Nina del Rocío Martínez–Ruiz Alma A.Vázquez–Flores Marcela Gaytán–Martínez Laura Ade la Rosa | 2021 | Food Production, Processing and Nutrition2021，3，1： | 0 |
| 4 | Freely Available Tool(FAT)for automated quantification of lipid droplets in stained cells显示文摘In this study,we propose an automatic procedure for digital image processing.We describe a method that can efficiently quantify and characterize lipid droplets distributions in different cell types in culture.Prospectively,the lipid droplets detection method described in this work could be applied to static or time-lapse data,collected with a simple visible light or fluorescence microscopy equipment.Fully automated algorithms were implemented in Octave,a freely available scientific package. | DIEGO MASONE ALDANA DGOJANOVICH YESICA R.FRONTINI-LOPEZ SAMANTA DEL VELIZ MARINA UHART DIEGO M.BUSTOS | 2017 | BIOCELL2017，41，2： | 0 |
| 5 | Experimental model standardizing polyvinyl alcohol hydrogel to simulate endoscopic ultrasound and endoscopic ultrasoundelastography显示文摘BACKGROUND Endoscopic ultrasound(EUS)and endoscopic ultrasound elastography(EUS-E)simulation lessens the learning curve;however,models lack realism,diminishing competitiveness.AIM To standardize the mechanical properties of polyvinyl alcohol(PVA)hydrogel for simulating organs and digestive lesions.METHODS PVA hydrogel(Sigma Aldrich,degree of hydrolysis 99%)for simulating EUS/EUS-E lesions was investigated in Unidad de Investigación y Desarrollo Tecnológico at Hospital General de México“Dr.Eduardo Liceaga”,Mexico City.We evaluated physical,contrast,elasticity and deformation coefficient characteristics in lesions,applying Kappa’s concordance and satisfaction questionnaire(Likert 4-points).RESULTS PVA hydrogel showed stable mechanical properties.Density depended on molecular weight(MW)and concentration(C).PVA bblocks with the greatest density showed lowest tensile strength(r=-0.8,P=0.01).Lesions were EUSgraphically visible.Homogeneous and heterogeneous examples were created from PVA blocks or PVA phantoms,exceeding(MW2=146000-186000,C9=15%and C10=20%)with a density under(MW1=85000-124000,C1=7%and C2=9%).We calculated elasticity and deformation parameters of solid(blue)areas,contrasting with the norm(Kappa=0.8;high degree of satisfaction).CONCLUSION PVA hydrogels were appropriate for simulating organs and digestive lesions using EUS/EUS-E,facilitating practice and reducing risk.Repetition amplified skills,while reducing the learning curve. | Elymir S Galvis-García Sergio Sobrino-Cossío Arturo Reding-Bernal Yesica Contreras-Marín Karina Solórzano-Acevedo Patricia González-Zavala Rosa M Quispe-Siccha | 2020 | World Journal of Gastroenterology2020，26，34： | 0 |
| 6 | Adipose-derived mesenchymal stem/stromal cells:from the lab bench to the basic concepts for clinical translation显示文摘In the last years,much work has shown that the most effective repair system of the body is represented by stem cells,which are defined as undifferentiated precursors that own unlimited or prolonged self-renewal ability,which also have the potential to transform themselves into various cell types through differentiation.All tissues that form the body contain many different types of somatic cells,along with stem cells that are called‘mesenchymal stem(or stromal)cells’(MSC).In certain circumstances,some of these MSC migrate to injured tissues to replace dead cells or to undergo differentiation to repair it.The discovery of MSC has been an important step in regenerative medicine because of their high versatility.Moreover,the finding of a method to isolate MSC from adipose tissue,so called‘adipose-derived mesenchymal stem cells’(ASC),which share similar differentiation capabilities and isolation yield that is greater than other MSC,and less bioethical concerns compared to embryonic stem cells,have created self-praised publicity to procure almost any treatment with them.Here,we review the current techniques for isolation,culture and differentiation of human ASC(hASC),and describe them in detail.We also compile some advantages of the hASC over other stem cells,and provide some concepts that could help finding strategies to promote their therapeutic efficiency. | Yesica Romina FRONTINI-LóPEZ Aldana Daniela GOJANOVICH Diego MASONE Diego Martín BUSTOS Marina UHART | 2018 | BIOCELL2018，42，3： | 0 |
