Potential effects of optical solar sail degredation on trajectory design [PDF]

, 2005
The optical properties of the thin metalized polymer films that are projected for solar sails are assumed to be affected by the erosive effects of the space environment.

The Relation Between Psychopathy and Sexual Aggression: A Meta‐Analysis

Journal of Personality, EarlyView.
ABSTRACT Objective Psychopathy is a multifaceted, hierarchical construct that has been linked to aggression and antisocial behavior. The triarchic model of psychopathy comprises three underlying, distinct trait domains: boldness, disinhibition, and meanness.

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States)

Journal of Phycology, EarlyView.
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).

Matrix Metalloproteinases in Periodontal and Peri‐Implant Diseases: Contribution to Their Pathogenesis, Diagnosis, and Treatment

Journal of Periodontal Research, EarlyView.
This graphical abstract illustrates the role of matrix metalloproteinases (MMPs) across the pathogenesis, diagnosis, and therapeutics of periodontal and peri‐implant diseases. Microbial and host stimuli trigger MMP activation leading to extracellular matrix breakdown, point‐of‐care aMMP‐8 detection aids diagnosis, and adjunctive or AI‐assisted ...

30 Years of Enamel Matrix Derivative (EMD): Biological Foundations and Systematic Review With Meta‐Analyses Across Multiple Clinical Indications

Journal of Periodontal Research, EarlyView.
EMD is one of the few biological agents with human histologic evidence supporting periodontal regeneration. This is reflected in improved clinical outcomes when used in regenerative surgery for intrabony defects. Despite its biological plausibility for broader therapeutic applications, further high‐quality randomized clinical trials are needed to ...

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

Journal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Platelet‐Rich Fibrins as Local Drug‐Delivery Carriers

Journal of Periodontal Research, EarlyView.
Autologous platelet concentrates (APCs), particularly platelet‐rich fibrin (PRF), act as biologically active fibrin scaffolds, capable of entrapping and gradually releasing therapeutic agents in oral and periodontal therapy. The incorporation of bioactive compounds, such as antibiotics, antifungals, vitamins, antidiabetic drugs, and exosomes, enhances ...

Crowding Out the Market: State Religious Policy and Social Capital Among Religious Adherents

Journal for the Scientific Study of Religion, EarlyView.
ABSTRACT How do governments’ policies toward religion impact the relationship between citizens and civil society? A large body of literature examines the effect of social capital on democratic governance. Studies of State Religious Policy, or SRP, however, have shown complex and potentially contradictory effects on different types of social capital ...
