Adjunctive use of omega-3 fatty acids in combination with low-dose aspirin in periodontitis: Systematic review and meta-analysis.

Periodontitis is one of the most common dental diseases with a range of treatment approaches, including pathogenetically reasonable use of various host immune modulators. One such approach is the use of omega-3 polyunsaturated fatty acids (PUFAs) in combination with low-dose aspirin. This systematic review and meta-analysis were performed to compare the standard treatment alone and adjunctive use of omega-3 PUFAs in combination with low-dose aspirin with or without standard treatment in patients with periodontitis.

On-Demand Cell Sheet Release with Low Density Peptide-Functionalized Non-LCST Polymer Brushes.

Cell sheet harvesting offers a great potential for the development of new therapies for regenerative medicine. For cells to adhere onto surfaces, proliferate, and to be released on demand, thermoresponsive polymeric coatings are generally considered to be required. Herein, an alternative approach for the cell sheet harvesting and rapid release on demand is reported, circumventing the use of thermoresponsive materials.

Bone Remodeling Interaction with Magnesium Alloy Implants Studied by SEM and EDX.

The development direction of bioresorbable fixing structures is currently very relevant because it corresponds to the priority areas in worldwide biotechnology development. Magnesium (Mg)-based alloys are gaining high levels of attention due to their promising potential use as the basis for fixating structures. These alloys can be an alternative to non-degradable metal implants in orthopedics, maxillofacial surgery, neurosurgery, and veterinary medicine.

Potentiometric Performance of Ion-Selective Electrodes Based on Polyaniline and Chelating Agents: Detection of Fe or Fe Ions.

We constructed a sensor for the determination of Fe and/or Fe ions that consists of a polyaniline layer as an ion-to-electron transducer; on top of it, chelating molecules are deposited (which can selectively chelate specific ions) and protected with a non-biofouling poly(2-methyl-2-oxazoline)s layer. We have shown that our potentiometric sensing layers show a rapid response to the presence of Fe or Fe ions, do not experience interference with other ions (such as Cu), and work in a biological environment in the presence of bovine serum albumin (as a model serum protein). The sensing layers detect iron ions in the concentration range from 5 nM to 50 µM.
