Implantable and transcutaneous photobiomodulation promote neuroregeneration and recovery of lost function after spinal cord injury.

Spinal cord injury (SCI) is a cause of profound and irreversible damage, with no effective therapy to promote functional recovery. Photobiomodulation (PBM) may provide a viable therapeutic approach using red or near-infrared light to promote recovery after SCI by mitigating neuroinflammation and preventing neuronal apoptosis. Our current study aimed to optimize PBM dose regimens and develop and validate the efficacy of an invasive PBM delivery paradigm for SCI.

An in vitro bioinspired approach to enhance the bioactivity of titanium implants via electrophoretic deposition and biomimetic mineralization of type i collagen.

Objective: This study aims to explore the efficacy of Electrophoretic Deposition (EPD) for collagen type I coating on titanium implants and its subsequent mineralization to improve osseointegration and bone regeneration.

Methods: Titanium disks were prepared with a sandblasted, large grit and acid-etched (SLA) surface. EPD was employed to deposit collagen type I onto the titanium surfaces, followed by two modes of mineralization: extra-fibril mineralization (EFM) and inter-fibril mineralization (IFM).

Developing an optimised method for accurate wear testing of dental materials using the 'Rub&Roll' device.

Dental materials are challenged by wear processes in the oral environment and should be evaluated in laboratory tests prior to clinical use. Many laboratory wear-testing devices are high-cost investments and not available for cross-centre comparisons. The 'Rub&Roll' wear machine enables controlled application of force, chemical and mechanical loading, but the initial design was not able to test against rigid antagonist materials.

Exposure to blue light reduces antimicrobial resistant isolated from dog ear infections.

Introduction: is a leading cause of canine otitis externa. Enrofloxacin is often applied topically to treat this condition, although recalcitrant and recurring infections are common. There is evidence that exposure to blue light (400-470 nm) has a bactericidal effect on and other microorganisms.

The effect of photoinitiator type and filler load on physicochemical and mechanical properties of experimental light-cured resin cements through lithium disilicate ceramics of different shades and thicknesses.

Objective: This study investigated the influence of photoinitiator types on degree of conversion (DC), rate of polymerization (RP), flexural strength (FS), flexural modulus (FM), and light transmittance (LT) of filled and unfilled light-curable resin cements through different thicknesses and shades of lithium disilicate ceramics.

Methods: Lithium disilicate ceramic discs (IPS Emax Press, background [0.0], 0.
