Broadband Passively Mode-Locked Fiber Laser with DNA Aqueous Solution as Saturable Absorber
Applied Sciences, 2021 We demonstrate a passively mode-locked fiber laser using aqueous DNA solution as a saturable absorber (SA), with broadband pulse laser emission from 1 to 1.5 µm.

Laser &Photonics Reviews, EarlyView.Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

Root surface biomodification in periodontal therapy: Biological rationale and clinical applications
Periodontology 2000, EarlyView.Abstract Regenerative periodontal therapy aims to form new cementum, periodontal ligament, and alveolar bone, all sealed by gingival tissue. The root surface acts as the wound margin during this regeneration process. Root surface biomodification (root conditioning/root decontamination), therefore, seems instrumental in promoting surface decontamination

Engineered surface strategies to manage dental implant‐related infections
Periodontology 2000, EarlyView.Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Periodontology 2000, EarlyView.Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Understanding exosomes in facial esthetics and skin aging
Periodontology 2000, EarlyView.Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Fiber-loop laser with a cooled erbium-doped section
Journal of the Optical Society of America BAn optical comb featuring an unusual structure has been recently observed in a fiber-loop laser running at cryogenic temperatures. In the present work, the effect of optical polarization on the operation of the laser is explored. Multi-mode lasing with a relatively high degree of inter-mode coherency is experimentally demonstrated.
