Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

open access: yesJournal of Phycology, EarlyView.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

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

open access: yesJournal 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).

Two Electron Diatomic Molecules : I. The James-Coolidge Method and Its Programs [PDF]

open access: yes, 1976
Computer programs which calculate energies and wave functions of two electron diatomic molecules by the James-Coolidge method are given. These programs can be applied to the singlet or the triplet Σ^+ states of two electron diatomic molecules of ...

Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

open access: yesMedical and Veterinary Entomology, EarlyView.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1904-1921, August 2026.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Exact Solutions of a Discrete Velocity Model of a Gas With Molecules Dissociation

open access: yesEngineering Transactions, 1991
We propose an elementary discrete velocity model of a gas, describing dissociation of diatomic molecules. We found exact analytical solutions to the following problems: 1) wave propagation in an unbounded domain; 2) boundary value problem with boundary ...

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1161-1171, August 2026.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...
