Biopolymer coating of soybean lecithin liposomes via layer-by-layer self-assembly as novel delivery system for ellagic acid

2010

Abstract The formulation of a novel delivery system for ellagic acid formulated via layer-by-layer (L-b-L) electrostatic deposition of biopolymers onto soybean lecithin liposomes was achieved. Optimization of parameters affecting the formulation of biopolymer-coated liposomes was carried out by monitoring changes on its size, surface charge and morphology. Ellagic acid was loaded into the liposome core and loading properties were analyzed. Release profiles for ellagic acid from optimized biopolymer-coated liposomes were evaluated as a function of time, temperature and pH of the media. The L-b-L electrostatic deposition of biopolymers succeeded in building nanosized, spherical and stable lip…

Is There a Future for Non-invasive Brain Stimulation as a Therapeutic Tool?

2019

Several techniques and protocols of non-invasive transcranial brain stimulation (NIBS), including transcranial magnetic and electrical stimuli, have been developed in the past decades. These techniques can induce long lasting changes in cortical excitability by promoting synaptic plasticity and thus may represent a therapeutic option in neuropsychiatric disorders. On the other hand, despite these techniques have become popular, the fragility and variability of the after effects are the major challenges that non-invasive transcranial brain stimulation currentlyfaces. Several factors may account for such a variability such as biological variations, measurement reproducibility, and the neurona…

Trunk Muscle Strength After Lumbar Spine Fusion: A 12-Month Follow-up.

2019

Objective: The aim of this study was to investigate changes in trunk muscle strength 12 months after lumbar spine fusion (LSF) compared to preoperative strength. Methods: A total of 194 patients (mean ± standard deviation [SD] age, 61 ± 21 years) who underwent LSF participated in this prospective longitudinal study. Physical measurements of the participants were made before surgery and 12 months postoperatively. Isometric trunk extension and flexion strength was measured using a strain-gauge dynamometer in the standing position. Strength changes were calculated. Regression analysis was performed to explore which factors predicted strength levels at 12 months postoperatively. Results: The pr…

A differential equation approach to implicit sweeping processes

2019

International audience; In this paper, we study an implicit version of the sweeping process. Based on methods of convex analysis, we prove the equivalence of the implicit sweeping process with a differential equation, which enables us to show the existence and uniqueness of the solution to the implicit sweeping process in a very general framework. Moreover, this equivalence allows us to give a characterization of nonsmooth Lyapunov pairs and invariance for implicit sweeping processes. The results of the paper are illustrated with two applications to quasistatic evolution variational inequalities and electrical circuits.

Isolation and Characterization of Listeria monocytogenes Phage vB_LmoH_P61, a Phage With Biocontrol Potential on Different Food Matrices

2020

The high mortality rate associated with Listeria monocytogenes as well as its ability to adapt to the harsh conditions employed in food processing have ensured that this pathogen has become a significant concern in the ready-to-eat food industry. Lytic bacteriophages are viruses that hijack their bacterial host’s metabolic mechanisms as a means to grow and replicate, subsequently leading to host cell death due to lysis. With emerging concerns related to the increasing numbers of antibiotic-resistant pathogens, bacteriophages may act as a suitable biocontrol alternative. This study reports the biological and genomic characterisation of the broad host range Listeria monocytogenes phage vB_Lmo…

Involving universities in regional upgrading in the periphery

2015

This chapter presents and discusses two cases of regional upgrading involving public-run universities in two Northern European countries, Norway and the Netherlands. More specifically, it illuminates how academic groups associated with the field of medicine took pro-active steps to establish and further develop regional coalitions which, over time, have resulted in situated learning. The focus on processes of university-regional engagement and mutual satisfaction in a context where universities are pressured to be globally excellent allow lessons to be drawn for regions in Southern Europe. Subtle transfer is nevertheless required to account for universities’ autonomies and organisational ca…

Revised annual post-market environmental monitoring (PMEM) report on the cultivation of genetically modified maize MON 810 in 2013 from Monsanto Euro…

2015

Question number: EFSA-Q-2015-00432On request from: European Commission; Following a request from the European Commission, the Panel on Genetically Modified Organisms of the European Food Safety Authority (EFSA GMO Panel) assessed the results of the general surveillance activities contained in the revised annual post-market environmental monitoring (PMEM) report for the 2013 growing season of maize MON 810 provided by Monsanto Europe S.A. The supplied data do not indicate any unanticipated adverse effects on human and animal health or the environment arising from the cultivation of maize MON 810 cultivation in 2013. Similar methodological shortcomings to those observed in previous annual PME…
