Effect of minor amounts of beta-calcium pyrophosphate and hydroxyapatite on the physico-chemical properties and osteoclastic resorption of beta-tricalcium phosphate cylinders

Paul Bowen, Gabrielle Anne Laguisma Sblendorio

beta-Tricalcium Phosphate (beta-TCP), one of the most used bone graft substitutes, may contain up to 5 wt% foreign phase according to standards. Typical foreign phases include beta-calcium pyrophosphate (beta-CPP) and hydroxyapatite (HA). Currently, the ef ...

In vitro and in vivo investigation of bisphosphonate-loaded hydroxyapatite particles for peri-implant bone augmentation

Dominique Pioletti, Ulrike Kettenberger

Locally applied bisphosphonates, such as Zoledronate, have been shown in several studies to inhibit peri-implant bone resorption and recently to enhance peri-implant bone formation. Studies have also demonstrated positive effects of hydroxyapatite particle ...

Active Agent-Particle Combination Supporting Bone Regeneration

Dominique Pioletti, Ulrike Kettenberger

The invention provides for a bioactive composition comprising solid particles, such as e.g. calcium phosphate particles, loaded with an active agent, preferably an osteoconductive/osteoinductive agent or an anti-resorptive agent like a bisphosphonate. The ...

Time course of bone screw fixation following a local delivery of zoledronate in a rat femoral model – a micro-finite element analysis

Dominique Pioletti, Alexandre Terrier, Ulrike Kettenberger, Adeliya Latypova

A good fixation of osteosynthesis implants is crucial for a successful bone healing but often difficult to achieve in osteoporotic patients. One possible solution to this issue is the local delivery of bisphosphonates in direct proximity to the implants, A ...

Tumor Vessel Normalization by Chloroquine Independent of Autophagy

Freddy Radtke

Chloroquine (CQ) has been evaluated as an autophagy blocker for cancer treatment, but it is unknown if it acts solely by inhibiting cancer cell autophagy. We report that CQ reduced tumor growth but improved the tumor milieu. By normalizing tumor vessel str ...

MULTI-ANALYTE DETECTION FOR BIOLOGICAL FLUIDS Towards Continous Monitoring of Glucose, Ionized Calcium and pH using a Viscometric Affinity Biosensor

Peter Ryser, Eric Meurville, Christophe Boss, Frédéric Schmitt, Pablo Dosil Rosende

We present a viscometric affinity biosensor that can potentially allow continuous multi-analyte monitoring in biological fluids like blood or plasma. The sensing principle is based on the detection of viscosity changes of a polymeric solution which has a s ...

Implants delivering bisphosphonate locally increase periprosthetic bone density in an osteoporotic sheep model. A pilot study

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

It is a clinical challenge to obtain a sufficient orthopedic implant fixation in weak osteoporotic bone. When the primary implant fixation is poor, micromotions occur at the bone-implant interface, activating osteoclasts, which leads to implant loosening. ...

Notch Inhibits Osteoblast Differentiation And Causes Osteopenia

Freddy Radtke

Notch receptors are determinants of cell fate decisions. To define the role of Notch in the adult skeleton, we created transgenic mice overexpressing the Notch intracellular domain (NICD) under the control of the type I collagen promoter. First generation ...

The effect of bisphosphonates and titanium particles on osteoblasts: an in vitro study

Dominique Pioletti, Bastian Peter

In an attempt to increase the life of cementless prostheses, an hydroxyapatite-coated implant which releases a bisphosphonate has been suggested as a drug-delivery system. Our in vitro study was designed to determine the maximum dose to which osteoblasts c ...

Calcium phosphate drug delivery system: influence of local zoledronate release on bone implant osteointegration

Dominique Pioletti, Bastian Peter

Despite total hip replacement (THR) gives generally satisfactory results, the quality of outcome in young patients is markedly decreased compared to the average THR outcome. For this population, pharmacological treatment with bisphosphonate would be benefi ...
