Current HPLC Methods for Assay of Nano Drug Delivery Systems

19-Apr-2017 | Evrim Kepekci Tekkeli, Serife; Volkan Kiziltas, Mustafa, Current Topics in Medicinal Chemistry, 2017

Abstract: In nano drug formulations the mechanism of release is a critical process to recognize controlled and targeted drug delivery systems. In order to gain high bioavailability and specificity from the drug to reach its therapeutic goal, the active substance must be loaded into the ...


Sensors, Vol. 17, Pages 888: A Latency and Coverage Optimized Data Collection Scheme for Smart Cities Based on Vehicular Ad-hoc Networks

18-Apr-2017 | Xu, Yixuan ; Chen, Xi ; Liu, Anfeng ; Hu, Chunhua, Sensors, 2017

Using mobile vehicles as “data mules” to collect data generated by a huge number of sensing devices that are widely spread across smart city is considered to be an economical and effective way of obtaining data about smart cities. However, currently most research focuses on the feasibility of the ...


Molecules, Vol. 22, Pages 623: Bioavailable Citrus sinensis Extract: Polyphenolic Composition and Biological Activity

15-Apr-2017 | Pepe, Giacomo ; Pagano, Francesco ; Adesso, Simona ; Sommella, Eduardo ; Ostacolo, Carmine ; Manfra, Michele ; Chiep ..., Molecules, 2017

Citrus plants contain large amounts of flavonoids with beneficial effects on human health. In the present study, the antioxidant and anti-inflammatory potential of bioavailable polyphenols from Citrus sinensis was evaluated in vitro and ex vivo, using the murine macrophages cell line J774A.1 and ...


Structural power and the evolution of collective fairness in social networks

14-Apr-2017 | Fernando P. Santos; Jorge M. Pacheco; Ana Paiva; Francisco C. Santos, PLoS ONE, 2017

by Fernando P. Santos, Jorge M. Pacheco, Ana Paiva, Francisco C. Santos From work contracts and group buying platforms to political coalitions and international climate and economical summits, often individuals assemble in groups that must collectively reach decisions that may favor each part ...


Sustainability, Vol. 9, Pages 610: The Implementation of Green Infrastructure: Relating a General Concept to Context and Site

14-Apr-2017 | Lindholm, Gunilla, Sustainability, 2017

In the quest for more sustainable urban landscape development, the concept of “green infrastructure” (GI) has become central in policy documents and as a multifunctional general planning tool. GI is not, however, a simple and unambiguous solution. While in policy documents there are claims for ...


Molecules, Vol. 22, Pages 627: Pro-Angiogenic Effects of Low Dose Ethoxidine in a Murine Model of Ischemic Hindlimb: Correlation between Ethoxidine Levels and Increased Activation of the Nitric Oxide Pathway

12-Apr-2017 | Clere, Nicolas ; To, Kim Hung Thien ; Legeay, Samuel ; Bertrand, Samuel ; Helesbeux, Jean Jacques ; Duval, Olivier ; ..., Molecules, 2017

Ethoxidine, a benzo[c]phenanthridine derivative, has been identified as a potent inhibitor of topoisomerase I in cancer cell lines. Our group has reported paradoxical properties of ethoxidine in cellular processes leading to angiogenesis on endothelial cells. Because low concentration ethoxidine ...


Transcriptomics and Lipidomics of the Environmental Strain Rhodococcus ruber Point out Consumption Pathways and Potential Metabolic Bottlenecks for Polyethylene Degradation

12-Apr-2017 | Kévin Gravouil; Romain Ferru-Clément; Steven Colas; Reynald Helye; Linette Kadri; Ludivine Bourdeau; Bouziane Moumen ..., Environmental Science & Technology, 2017

Polyethylene (PE), one of the most prominent synthetic polymers used worldwide, is very poorly biodegradable in the natural environment. Consequently, PE represents by itself more than half of all plastic wastes. PE biodegradation is achieved through the combination of abiotic and biotic ...


Formation of BaFe12‐xNbxO19 and its high electromagnetic wave absorption properties in millimeter wave frequency range

11-Apr-2017 | Chuyang Liu, Yujie Chen, Yangyu Yue, Yu Tang, Zongrong Wang, Ning Ma, Piyi Du, Journal of the American Ceramic Society, 2017

Abstract BaFe12‐xNbxO19 (BFNO, x=0~0.6) powders with Nb5+ substituting for Fe3+ were prepared by sol‐gel method. The formation process and electromagnetic (EM) wave absorption properties of the BFNO are investigated in detail. With Nb5+ content increasing from x=0 to x=0.6, the formation ...


Non-equilibrium supramolecular polymerization

05-Apr-2017 | Alessandro Sorrenti; Jorge Leira-Iglesias; Albert J. Markvoort; Tom F. A. de Greef; Thomas M. Hermans, Chemical Society Reviews, 2017

Supramolecular polymerization has been traditionally focused on the thermodynamic equilibrium state, where one-dimensional assemblies reside at the global minimum of the Gibbs free energy. The pathway and rate to reach the equilibrium state are irrelevant, and the resulting assemblies remain ...


The push-and-pull hypothesis in protein unfolding, misfolding and aggregation

03-Apr-2017 | Author(s): Guilherme A.P. de Oliveira, Jerson L. Silva, Biophysical Chemistry, 2017

Publication date: Available online 29 March 2017 Source:Biophysical Chemistry Author(s): Guilherme A.P. de Oliveira, Jerson L. Silva The combination of biophysical and structural techniques has allowed the visualization of species classified as dry molten-globule states. Further ...
