Platelet-rich plasma (PRP) contains growth factors which positively affect cell proliferation, cell differentiation, chemotaxis and intracellular matrix synthesis. All these processes are involved in wound healing and tissue regeneration; thus, PRP as a source of growth factors can be used in periodontal regenerative therapies. The purpose of the present study was to assess the effect of various concentrations of activated and non-activated PRP on proliferation of osteoblasts and fibroblasts in vitro. PRP was obtained from three healthy volunteers...

Cartilage tissue engineering based on biomimetic scaffolds has become a rapidly developing strategy for repairing cartilage defects. In this study, a biphasic CAN-PAC hydrogel for osteochondral defect (OCD) regeneration was fabricated based on the density difference between the two layers via a thermally reactive, rapid cross-linking method. The upper hydrogel was cross-linked by CSMA and NIPAm, and the lower hydrogel was composed of PECDA, AAm and PEGDA. The interface between the two layers was first grafted by the physical cross-linking of calcium gluconate and alginate, followed by the chemical cross-linking of the carbon-carbon double bonds in the other components...

Maintenance of physiological levels of intracellular and extracellular calcium is essential for life. Increased intracellular calcium levels are involved in cell death (apoptosis and necrosis) and are associated with positive responses in the Comet assay in vitro. In addition, high calcium and vitamin D intakes were reported to induce apoptosis in adipose tissue in obese mice and to increase DNA-migration in the Comet assay. To investigate increased serum concentration of calcium as a potential confounding factor in the regulatory Comet assay in vivo, we induced mild hypercalcemia in male Wistar rats by 3-day continuous intravenous infusion of calcium gluconate and performed the Comet assay in the liver in line with regulatory guidelines...

BACKGROUND: Platelet-rich and platelet poor plasma (PRP and PPP) are autologous preparations from peripheral blood and contain several growth factors and cytokines involved in tissue repair. Although their neuroprotective and -regenerative properties have been already described, little is known about their effects in the inner ear. We therefore examined the effects of PRP and PPP on spiral ganglion neurons (SGN) in vitro. RESULTS: For all experiments, spiral ganglia were isolated from neonatal rats and were cultured in serum-free medium...

Propafenone is prescribed for the control of cardiac ventricular arrhythmias. Poisoning from propafenone intoxication is rare, but the survival rate of patients is low. We present a case of a 37-year-old man who developed cardiac arrest due to propafenone intoxication. Cardiopulmonary resuscitation, plasmapheresis, and other medical treatments had no effect on cardiac arrest. After repeated administrations of calcium gluconate, the patient achieved a full recovery. To the best of our knowledge, this is the first case report in which a full recovery from cardiac arrest was achieved by administration of calcium gluconate...
