Impacts of predator odours and conspecific disturbance cues on minnow thermal tolerance

Journal of Fish Biology, EarlyView.
Abstract Warming waters can affect fish community dynamics, potentially exacerbating predator–prey asymmetries in behavioural and physiological metrics of thermal tolerance. Further, differing responses of prey fish species to concurrent predation risk and warming highlight the need to understand these impacts in various contexts, especially with at ...

Effect of hydroxyurea on mitotic activity 3H-thymidine and 3H-phenylalanine incorporation in the antheridial filament cells of Chara vulgaris

Acta Societatis Botanicorum Poloniae, 2015
Hydroxyurea inhibits mitotic activity in cells of the antheridial filaments of Chara vulgaris by blocking phase S and phase G2. Blocking of cells in phase G2 also occurs in the case of the root meristem cells of Helianthus annuus and Vicia faba var ...

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Is Chara corallina a suitable model plant for studying cell-failure mechanisms in fruit skins?

Journal of Applied Botany and Food Quality, 2021
The freshwater alga, Chara corallina, is often used as a model system in studies of cell-wall mechanics. Chara has a unique and very simple architecture, in which a number of node cells form the interface between two giant internode cells.

Salivary Viscosity as a Non‐Invasive Candidate Biomarker Associated With Aspiration Risk in Oculopharyngeal Muscular Dystrophy

Journal of Oral Rehabilitation, EarlyView.
Patients with oculopharyngeal muscular dystrophy exhibit disease‐specific salivary hyperviscosity that tracks with dysphagia severity and airway invasion. Non‐invasive chairside screening of salivary viscosity may enable clinicians to stratify aspiration risk during routine care to prevent severe pulmonary complications.

Modeling the Action Potential in Characeae Nitellopsis obtusa: Effect of Saline Stress

Frontiers in Plant Science, 2019
Action potentials (AP) of characean cells were the first electrical transients identified in plants. APs provide information about plethora of environmental cues. Salinity stress is critical for plants and impacts on excitability.
