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.

Novel and emerging antimicrobial strategies in the management of oral infections
Periodontology 2000, EarlyView.Abstract Background Antibiotics marked a pivotal turning point in human civilization, enhancing social interactions and extending human life expectancy. In addition to their success in treating systemic infectious diseases, they have significantly improved periodontal treatment outcomes as an adjunct therapy.

Microbial Eukaryotes that Lack Sterols
Journal of Eukaryotic Microbiology, 2017AbstractIt is widely held that sterols are key cyclic triterpenoid lipids in eukaryotic cell membranes and are synthesized through oxygen‐dependent multienzyme pathways. However, there are known exceptions―ciliated protozoans, such as Tetrahymena, along with diverse low‐oxygen‐adapted eukaryotes produce, instead of sterols, the cyclic triterpenoid ...

Genome diversity in microbial eukaryotes
Trends in Ecology & Evolution, 2004The genomic peculiarities among microbial eukaryotes challenge the conventional wisdom of genome evolution. Currently, many studies and textbooks explore principles of genome evolution from a limited number of eukaryotic lineages, focusing often on only a few representative species of plants, animals and fungi. Increasing emphasis on studies of genomes

Spatial scaling of microbial eukaryote diversity
Nature, 2004Patterns in the spatial distribution of organisms provide important information about mechanisms that regulate the diversity of life and the complexity of ecosystems. Although microorganisms may comprise much of the Earth's biodiversity and have critical roles in biogeochemistry and ecosystem functioning, little is known about their spatial ...

Energetics and evolution of anaerobic microbial eukaryotes
Nature Microbiology, 2023Mitochondria and aerobic respiration have been suggested to be required for the evolution of eukaryotic cell complexity. Aerobic respiration is several times more energetically efficient than fermentation. Moreover, aerobic respiration occurs at internalized mitochondrial membranes that are not constrained by a sublinear scaling with cell volume ...

2013
A bioinformatics survey of about 120 protist and 240 fungal genomes and transcriptomes revealed a broad array of globins, representing five of the eight subfamilies identified in bacteria. Most conspicuous is the absence of protoglobins and globin-coupled sensors, except for a two-domain globin in Leishmanias, that comprises a nucleotidyl cyclase ...

The voyage of the microbial eukaryote
Current Opinion in Microbiology, 2010Although genome data from unicellular marine eukaryotes is sparse, sequences from several supergroups have initiated an era of genome-enabled research aimed at understanding gene function, evolution, and adaptation in non-traditional model protists. Trends in genomic content within and between different lineages are emerging, including phylogenetically

Cosmopolitan Metapopulations of Free-Living Microbial Eukaryotes
Protist, 2004Metapopulations of macroscopic organisms tend to be geographically restricted, but free-living protists and other microbial eukaryotes present a different picture. Here we show that most organisms smaller than 1 mm occur worldwide wherever their required habitats are realised.
