Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Microplastics Effects on Reproduction and Body Length of the Soil-Dwelling Nematode Caenorhabditis elegans

Frontiers in Environmental Science, 2020
Microplastics (MP) are pervasive in the environment. There is ample evidence of negative MP effects on biota in aquatic ecosystems, though little is known about MP effects in terrestrial ecosystems.

Schiff based derived homogeneous catalysts for ring‐opening terpolymerization

Polymer International, EarlyView.
One‐pot synthesis of degradable terpolymers from l‐lactide, propylene oxide and CO₂ using diverse catalysts is described, revealing structure–property relationships for tailored applications in sustainable materials. Abstract In this study, we synthesized and evaluated a series of Schiff base cobalt catalysts for the terpolymerization of propylene ...

Characterization of Poly(L-lactide) and Poly(D-lactide) blends by solution casting process [PDF]

Warasan Witthayasat Lae Theknoloyi Mahawitthayalai Mahasarakham, 2019
Polylactide is the most widely used biodegradable polymer. The high thermal stability and mechanical properties of polylactide makes permit a wide range of industrial applications. Polylactide has two isomers; Poly (L-lactide) (PLLA) and Poly (D-lactide)

Block Versus Particulate Deproteinized Bovine Bone Mineral for Guided Bone Regeneration of Peri‐Implant Dehiscence Defects: A 5‐Year Randomized Controlled Trial

Clinical Oral Implants Research, EarlyView.
ABSTRACT To assess the 5‐year dimensional stability of buccal hard‐tissues following guided bone regeneration (GBR) of peri‐implant dehiscence defects using deproteinized bovine bone mineral (DBBM) blocks or particulate. Methods Patients requiring single‐tooth implants and presenting a buccal dehiscence defect (≥ 3 mm) at implant placement were ...

Effect of Membrane Perforations With and Without Collagen Membrane Coverage in Vertical Ridge Augmentation: An Experimental Pilot In Vivo Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives Given the proposed bioactive role of collagen membranes, we aimed to evaluate whether the perforation size of titanium‐reinforced dPTFE membranes, with or without an additional collagen membrane, influences outcomes of vertical alveolar ridge augmentation (VARA).

Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

Journal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

Cell Therapy for Periodontal, Soft‐Tissue, and Craniofacial Regeneration

Journal of Periodontal Research, EarlyView.
The clinical translation of mesenchymal stem/stromal cells (MSCs) represents a major advancement in dentistry, especially for periodontal, soft‐tissue, and craniofacial regeneration. However, several challenges remain to be addressed, including the absence of standardised protocols, limited scalability, regulatory hurdles, a lack of well‐controlled ...

Mystery and misery of locally‐delivered drug therapy in periodontics. Historical concepts and current state

Periodontology 2000, EarlyView.
Abstract The primary objective is to critically analyze approaches to local therapy for periodontal disease, particularly in light of its well‐established systemic implications. We specifically address common misconceptions and overestimations regarding the potential of local treatments in contrast to their actual clinical effectiveness.
