Crestal approach for repair of oroantral bone defects and subsequent implant placement
Clinical Advances in Periodontics, EarlyView.Abstract Background Oroantral communication (OAC) can occur after a dental extraction. Occasionally, bony defects may persist despite successful soft tissue closure of the OAC. The absence of bone in these areas poses challenges for dental implant placement.

Poroelasticity of (bio)polymer networks during compression: theory and experiment [PDF]
arXiv, 2019 Soft living tissues like cartilage can be considered as biphasic materials comprised of a fibrous complex biopolymer network and a viscous background liquid. Here, we show by a combination of experiment and theoretical analysis that both the hydraulic permeability and the elastic properties of (bio)polymer networks can be determined with simple ramp ...

Multimodal CARS and SHG microscopy for label-free detection of collagen produced by hDFs in fibrin gel [PDF]
arXiv, 2011 Label-free combined CARS and SHG microscopy techniques are used as powerful tool to follow the cells behavior in cell-scaffold construct for regeneration of tissues. Imaging of histological section of hDFs seeded in fibrin gel scaffold and imaging of collagen produced by hDFs in a time course experiment at different culture days (0, 7, 21, 42) is ...

Molecular Mechanism of Transition from Catch-Bond to Slip-Bond in Fibrin [PDF]
arXiv, 2017 The lifetimes of non-covalent A:a knob-hole bonds in fibrin probed with the optical trap-based force-clamp first increases ("catch bonds") and then decreases ("slip bonds") with increasing tensile force. Molecular modeling of "catch-to-slip" transition using the atomic structure of the A:a complex reveals that the movable flap serves as tension ...

Exploration, EarlyView.Schematic illustration of structural and functional biomimicry. The upper part shows BP with various structures such as monolayered, surface‐microstructural, bilayered and multilayered. The bottom part exhibits BP with different functions including immune regulation, drugs/cells/factors/ions loading, as well as bioelectrical stimulation and ...

Application of Biomaterials for the Prevention of Pharyngeal Fistulae: A Systematic Review
Head &Neck, EarlyView.ABSTRACT Background PharyngoCutaneous Fistulae (PCF) represent a significant clinical challenge in otorhinolaryngology practice. The use of biomaterials could improve outcomes or even replace the use of a flap in pharyngolaryngeal surgery. Methods This systematic review included all studies evaluating the application of biomaterials for the prevention ...

Microscopy Research and Technique, EarlyView.The study concludes that while both T‐PRF and L‐PRF aid in bone regeneration, L‐PRF shows superior efficacy. L‐PRF is recommended for bone defect healing due to its better performance in enhancing bone parameters. The density of the defect area (red circle) treated with L‐PRF extract demonstrates strong integration due to its close resemblance to ...

Efficacy of Platelet Rich Fibrin on Angiogenesis
The Journal of Duhok University, 2020 In this experiment we used platelet-rich fibrin (L-PRF) with the protocol of its production, in this study we tried to investigate the angiogenetic efficacy of L-PRF on s soft tissue. Blood samples of 8 sheep were used to establish the protocol of the L-PRF formation to develop the work. The mucoperiosteal flaps were filled with autologous L-PRF in the
