Human nasoseptal chondrocytes maintain their differentiated phenotype on PLLA scaffolds produced by thermally induced phase separation and supplemented with bioactive glass 1393
Damage of hyaline cartilage such as nasoseptal cartilage requires proper reconstruction, which remains challenging due to its low intrinsic repair capacity. Implantation of autologous chondrocytes in combination with a biomimetic biomaterial represents a promising strategy to support cartilage repair. Despite so far mostly tested for bone tissue engineering, bioactive glass (BG) could exert stimulatory effects on chondrogenesis. The aim of this work was to produce and characterize composite porous poly(L-lactide) (PLLA)/1393BG scaffolds via thermally induced phase separation (TIPS) technique and assess their effects on chondrogenesis of nasoseptal chondrocytes. The PLLA scaffolds without or…
Sociodemographic Characteristics and Interests of FeverApp Users
The FeverApp Registry is a model registry focusing on pediatric fever using a mobile app to collect data and present recommendations. The recorded interactions can clarify the relationship between user documentation and user information. This initial evaluation regarding features of participants and usage intensity of educational video, information library, and documentation of fever events covers the runtime of FeverApp for the first 14 months. Of the 1592 users, the educational opening video was viewed by 41.5%, the Info Library was viewed by 37.5%, and fever events were documented by 55.5%. In the current sample, the role of a mother (p <
Das FieberApp Register – ein Weg, um Eltern durch eigene Dokumentation zu einer abgestuften Entscheidung zu führen
Zusammenfassung Ziel der Studie Die Machbarkeit und Modellhaftigkeit eines App-basierten Eltern-Registers ist aufzuzeigen. Methodik Die FeverApp als interaktives Erfassungsinstrument und die zugrundeliegende Datenstruktur des Registers werden vorgestellt. Die bisherigen Rekrutierungsbemühungen werden veranschaulicht und die Temperaturverteilung, sowie die Verteilung von Fieberereignissen im Jahr 2020 werden analysiert. Ergebnisse Die FeverApp sammelt erfolgreich Daten in ein zentrales Register. Wie jede Studie informiert sie zudem über das aktuelle Wissen. Die naturalistisch erfassten, aktuellen Werte können auf die Krankheitssituation mehrere Ebenen (Messung, Fieberphase, Individuum, Famil…
Biological characterization of Poly-L-lactic acid (PLLA)/Hydroxyapatite (HA)/Bioglass (BG) composite scaffolds made by Thermally Induced Phase Separation (TIPS) hosting human Mesenchymal Stem Cells
In the last few years, Tissue Engineering has focused on the favourable effects that composite scaffolds have on cell adhesion, growth and differentiation. In fact, composite scaffolds, usually composed of a synthetic polymer supplemented with naturally occurring components, display superior mechanical properties and bioconductivity than scaffolds consisting of a single component. Hydroxyapatite (HA) is the major inorganic component of bones. Bioglass (BG) is known to exert stimulatory effects on cells by ion release and hence, could be also advantageous for Bone Tissue Engineering. Poly-L-lactic acid (PLLA) is a versatile synthetic polymer combinable with HA and BG. The aim of this work wa…
