Six-Week Endurance Exercise Alters Gut Metagenome That Is not Reflected in Systemic Metabolism in Over-weight Women
2018
Recent studies suggest that exercise alters the gut microbiome. We determined whether six-weeks endurance exercise, without changing diet, affected the gut metagenome and systemic metabolites of overweight women. Previously sedentary overweight women (n = 19) underwent a six-weeks endurance exercise intervention, but two were excluded due to antibiotic therapy. The gut microbiota composition and functions were analyzed by 16S rRNA gene amplicon sequencing and metagenomics. Body composition was analyzed with DXA X-ray densitometer and serum metabolomics with NMR metabolomics. Total energy and energy-yielding nutrient intakes were analyzed from food records using Micro-Nutrica software. Serum…
Extracellular vesicles from a renewable natural source: development of new biomaterials
2023
Le vescicole extracellulari (EV) sono nanoparticelle membranose derivate dalle cellule che mediano la comunicazione intercellulare trasferendo composti bioattivi come proteine e RNA. La scoperta delle EV come nanotecnologie naturali e mezzi di comunicazione tra cellule e persino tra specie ha suscitato grande interesse nel campo della somministrazione di farmaci. Le EV possiedono intrinsecamente diversi attributi che le rendono un buon veicolo per il rilascio di farmaci in organi e tessuti bersaglio specifici. Infatti, queste particelle: i) sono ben tollerate nel corpo, ii) hanno una lunga emivita circolante, iii) vengono internalizzate dalle cellule riceventi e iv) sono capaci di attravers…

Structural studies of dielectric polymer nanocomposites
2013
A constant need for the development of new and superior materials is always present; for example, a better electrical insulator would enable more efficient use of electrical power. Polymeric nanocomposites, i.e. nanodielectrics, are thought to have unique electrical properties. The basic chemical constitution of a material alone fails to provide an understanding of how desired properties of a material originate or predict the long term behavior of a material. We need to define the structure behind the functionality of a material. To do that, the structure of the material must be studied on several scales. This research was part of the Finnish Funding Agency for Technology and Innovation (TE…
Supramolecular Modification of ABC Triblock Terpolymers in Confinement Assembly
2018
The self-assembly of AB diblock copolymers in three-dimensional (3D) soft confinement of nanoemulsions has recently become an attractive bottom up route to prepare colloids with controlled inner morphologies. In that regard, ABC triblock terpolymers show a more complex morphological behavior and could thus give access to extensive libraries of multicompartment microparticles. However, knowledge about their self-assembly in confinement is very limited thus far. Here, we investigated the confinement assembly of polystyrene-block-poly(4-vinylpyridine)-block-poly(tert-butyl methacrylate) (PS-b-P4VP-b-PT or SVT) triblock terpolymers in nanoemulsion droplets. Depending on the block weight fractio…
