Controllable performance of a dopamine-modified silk fibroin-based bio-adhesive by doping metal ions.

Biomed Mater 2021 May 12. Epub 2021 May 12.

Zhejiang Sci-Tech University, Hangzhou 310018, Zhejiang Sci-Tech University, Hangzhou 310018 hangzhou, CN, Hangzhou, 310018, CHINA.

Bio-adhesives are essential for wound healing because of their convenience and safety. Although widely used as biomaterials, silk fibroin (SF)'s further application as bio-adhesive is hindered due to its weak stickiness with tissue and slow gelation speed. Here, a dopamine-modified silk fibroin-based bio-adhesive is fabricated by using genipin as the chemical cross-linking agent. Read More

Non-Covalent Microarrays from Synthetic Amino-Terminating Glycans-Implications in Expanding Glycan Microarray Diversity and Platform Comparison.

Glycobiology 2021 May 8. Epub 2021 May 8.

Glycosciences Laboratory, Imperial College London, London W12 0NN, United Kingdom.

Glycan microarrays have played important roles in detection and specificity assignment of glycan-recognition by proteins. However, the size and diversity of glycan libraries in current microarray systems are small compared to estimated glycomes, and these may lead to missed detection or incomplete assignment. For microarray construction, covalent and non-covalent immobilization are the two types of methods used, but a direct comparison of results from the two platforms is required. Read More

In Vitro Measurements of Shear-Mediated Platelet Adhesion Kinematics as Analyzed through Machine Learning.

Ann Biomed Eng 2021 May 10. Epub 2021 May 10.

Department of Biomedical Engineering, T08-50 Health Sciences Center, Stony Brook University, Stony Brook, NY, 11794-8084, USA.

Platelet adhesion to blood vessel walls in shear flow is essential to initiating the blood coagulation cascade and prompting clot formation in vascular disease processes and prosthetic cardiovascular devices. Validation of predictive adhesion kinematics models at the single platelet level is difficult due to gaps in high resolution, dynamic morphological data or a mismatch between simulation and experimental parameters. Gel-filtered platelets were perfused at 30 dyne/cm in von Willebrand Factor (vWF)-coated microchannels, with flipping platelets imaged at high spatial and temporal resolution. Read More

Laser assisted sampling vs direct desorption flowing atmospheric pressure afterglow mass spectrometry of complex polymer samples: Forensic implications for pressure sensitive tape chemical analysis.

Talanta 2021 Aug 27;231:122333. Epub 2021 Mar 27.

Department of Chemistry and Biochemistry, Texas Tech University, Lubbock, TX, 79409-1061, USA. Electronic address:

Flowing atmospheric pressure afterglow (FAPA) mass spectrometry (MS) is an easy-to-use, cost-effective, and potentially portable technique that allows direct desorption/ionization from samples with little-to-no sample preparation for real-time chemical analysis. However, it has limitations regarding analytes with low desorption efficiency, such as polymers. Here, laser assisted sampling (LAS) is developed and coupled to FAPA MS to allow access to a wider range of chemical information from polymer samples. Read More

Released Myeloperoxidase Attenuates Neutrophil Migration and Accumulation in Inflamed Tissue.

Front Immunol 2021 20;12:654259. Epub 2021 Apr 20.

Department of Pathology, Northwestern University Feinberg School of Medicine, Chicago, IL, United States.

Neutrophil (PMN) recruitment to sites of insult is critical for host defense, however excessive PMN activity and tissue accumulation can lead to exacerbated inflammation and injury. Myeloperoxidase (MPO) is a PMN azurophilic granule enzyme, which together with HO, forms a powerful antimicrobial system designed to kill ingested bacteria. Intriguingly, in addition to intracellular killing of invading microorganisms and extracellular tissue damage due generation of ROS, soluble MPO has been directly implicated in modulating cellular responses and tissue homeostasis.

Evaluation of fracture resistance of zirconia modification/polishing around implant abutments.

J Oral Implantol 2021 May 4. Epub 2021 May 4.

Associate Professor, Phillip Maurer Tennis Professor of Clinical Dentistry, Assistant Director of Advanced Prosthodontics, Director of Predoctoral Implant Dentistry, Herman Ostrow School of Dentistry, University of Southern California, Los Angeles, Califor.

Subcrestal placement of implants may have interproximal bone proximity issues that interfere with submucosal contour of the implant-supported Zirconia restorations during delivery of these restorations.  Modification of the mesial distal submucosal areas may be necessary to fully seat the restoration without impingement of the interproximal bone. Our aim was to determine if modification of submucosal cervical contour of implant supported zirconia titanium base (Zi-Ti base) restorations result in a significant change in fracture strength compared to Zi-Ti base restorations without any modification near the cervical submucosal area.
