© 2021 The Authors. Legume Science published by Wiley Periodicals LLC.The main aim of the article was to produce gallic acid-loaded pea flour/polyethylene oxide (PEO)-based nanofibers through the electrospinning method as an alternative active packaging material. Incorporation of gallic acid caused significant changes in both solution properties and fiber morphology. Increasing gallic acid concentration resulted in increasing conductivity and decreasing consistency index, by the way decreasing average fiber size diameter. In thermogravimetric analysis (TGA), gallic acid addition resulted in a decrease in thermal degradation value of nanofibers. In addition to these changes, new chemical bands formed were an indicator of the successful encapsulation of gallic acid in Fourier-transform infrared (FTIR) spectra. Nanofibers also showed promising results in terms of encapsulation of bioactive compounds. Therefore, gallic acid-loaded pea flour/PEO-based nanofibers might be considered as a promising active packaging material.

Licensee MDPI, Basel, Switzerland.Meso-substituted borondipyrromethene (BODIPY)-porphyrin compounds that include free base porphyrin with two different numbers of BODIPY groups (BDP-TTP and 3BDP-TTP) were designed and synthesized to analyze intramolecular energy transfer mechanisms of meso-substituted BODIPY-porphyrin dyads and the effect of the different numbers of BODIPY groups connected to free-base porphyrin on the energy transfer mechanism. Absorption spectra of BODIPY-porphyrin ...
Nanostructured modifications of titanium surfaces improve vascular regenerative properties of exosomes derived from mesenchymal stem cells: Preliminary in vitro results

© 2021 by the authors. Licensee MDPI, Basel, Switzerland.(1) Background: Implantation of metal-based scaffolds is a common procedure for treating several diseases. However, the success of the long-term application is limited by an insufficient endothelialization of the material surface. Nanostructured modifications of metal scaffolds represent a promising approach to faster biomaterial osteointegration through increasing of endothelial commitment of the mesenchymal stem cells (MSC).

Bacterial cellulase production using grape pomace hydrolysate by shake-flask submerged fermentation
Kurt, Ayse Sultan; Çekmecelioğlu, Deniz (2021-01-01)
© 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Grape pomace is a lignocellulosic waste of wine industry, which comprises high moisture content, cellulose, and hemicellulose, making it a viable substrate to microorganisms. Also, it is a potential substrate for bio-products such as enzymes and biofuels. Thus, the aim of the study was at the optimization of solid to liquid ratio (w/v), pH, and fermentation period for maximal cellulase of Bacillus subtili...
Activity-Based Photosensitizers with Optimized Triplet State Characteristics Toward Cancer Cell Selective and Image Guided Photodynamic Therapy
Kilic, Eda; ELMAZOĞLU, ZÜBEYİR; Almammadov, Toghrul; KEPİL, DİLAY; Etienne, Thibaud; Marıon, Antoıne; Günbaş, Emrullah Görkem; Kolemen, Safacan (2022-01-01)
© 2022 The Authors. Published by American Chemical Society.Activity-based theranostic photosensitizers are highly attractive in photodynamic therapy as they offer enhanced therapeutic outcome on cancer cells with an imaging opportunity at the same time. However, photosensitizers (PS) cores that can be easily converted to activity-based photosensitizers (aPSs) are still quite limited in the literature. In this study, we modified the dicyanomethylene-4H-chromene (DCM) core with a heavy iodine atom to get two ...
Co-adaptation in Context with Iranian, Russian and Turkish Policies on Syrian Complexity: The Emergence of the Astana Process
Çoban, Mehmet İlbey (2021-01-01)
© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.This research is based on explaining the dynamics that led the Iran, Russia and Turkey to initiate Astana Process within the framework of the Syrian Civil War’s changing dynamics. The article intends to combine power politics with the “complexity” paradigm. Linear ontology is problematic in explaining the changing dynamics. On the other hand, the complexity paradigm explains non-linear processes derived from its ontological fou...
