[Analysis of influencing factors on the height of gingival papilla around implants].

The anatomical structure of the gingival papilla around the implant is special, and it is difficult to recover after injury. The reduction of its height will have a negative impact on function and esthetics, and it is one of the many problems in implant treatment at present. This paper analyzes the influencing factors of implant gingival papilla height from three aspects: anatomical factors, implant surgical design and implant restorative design, including the classical influencing factors such as the shape of natural teeth, interproximal distance between the implant and the adjacent tooth, soft tissue grafting, and contour of implant restorations, as well as the hot and controversial influencing factors in recent years such as the thickness of soft tissues around the implant, the implant surgical timing, the flap design, and the surgical incision, in order to provide reference for clinicians in the process of implant treatment for gingival papilla preservation and reconstruction.

Alpha-synuclein inhibits the secretion of extracellular vesicles through disruptions in YKT6 lipidation.

Parkinson's disease is characterized by the presence of α-synuclein (α-syn) primarily containing Lewy bodies in neurons. Despite decades of extensive research on α-syn accumulation, its molecular mechanisms have remained largely unexplored. Recent studies by us and others have suggested that extracellular vesicles (EVs), especially exosomes, can mediate the release of α-syn from cells, and inhibiting this pathway could result in increased intracellular α-syn levels.

Recombinant collagen microneedles for transdermal delivery of antibacterial copper-DNA nanoparticles to treat skin and soft tissue infections.

Skin and soft tissue infections (SSTI) include bacterial infections of the skin, muscles, and connective tissue such as ligaments and tendons. SSTI in patients with immunocompromising diseases may lead to chronic, hard-to-heal infected wounds, resulting in disability, amputation, or even death. To treat SSTI and rebuild the defensive barrier of the skin, here we utilize recombinant type XVII collagen protein (rCol XVII) to construct biodegradable, regenerative collagen microneedles (rCol-MNs) for transdermal delivery of antibacterial agents.
