Horizontal platelet-rich fibrin versus advanced platelet-rich fibrin plus in gingival recession management.

Background: Newer generation platelet concentrates, such as advanced platelet-rich fibrin plus (A-PRF+) obtained following low-speed centrifugation concept and horizontal platelet-rich fibrin (H-PRF) obtained from swing out and bucket system, showed increased platelet entrapment and growth factor release in the in-vitro studies. This prospective study aimed to evaluate and compare the clinical outcomes of A-PRF+ and H-PRF membranes in the treatment of gingival recession defects. The objectives of this study were to compare the changes in the recession height (RH) and the mean root coverage percentage (MRC%) between and within the research groups.

Centrifugation is crucial for size and density-based sample separation, but low-volume or delicate samples suffer from loss and impurity issues during repeated spins. We introduce the "Spinochip", a novel microfluidic system utilizing centrifugal forces for efficient filling of dead-end microfluidic channels. The Spinochip enables versatile fluid manipulation with a single reservoir for both inlet and outlet functions.

This study evaluated the properties of lentil protein, pea protein, quinoa protein, and soy protein as natural nanoparticle stabilizers and their interactions with pectin and chitin nanofiber in preparing high internal phase Pickering emulsions (HIPPEs). The globular plant proteins interact with polysaccharides through hydrogen bonding and electrostatic interactions, transforming the structure into complex morphologies, including fibrous and elliptical shapes. These complex nanoparticles exhibited enhanced thermal decomposition stability, and the HIPPEs constructed by them demonstrated significantly improved apparent viscosity and elastic modulus, with a yield stress of 931.

This paper explores the applicability of bicycle-inspired balance control in a quadruped robot model. Bicycles maintain stability and change direction by intuitively steering the handle, which induces yaw motion in the body frame and generates an inertial effect to support balance. Inspired by this balancing strategy, we implemented a similar mechanism in a quadruped robot model, introducing a yaw trunk joint analogous to a bicycle's steering handle.

The extracellular vesicle release in red blood cell concentrates reflects progressive accumulation of storage lesions and could represent a new measure to be implemented routinely in blood centres in addition to haemolysis. Nevertheless, there is currently no standardized isolation protocol. In a previous publication, we developed a reproducible ultracentrifugation-based protocol (20,000 × protocol) that allows to classify red blood cell concentrates into three cohorts according to their vesiculation level.
