Quantification of multiple environmental controls on lipid biomarkers in common marine diatoms and dinoflagellates
<p>In the monocultures of two algal species, i.e., <em>Phaeodactylum tricornutum</em> (Bacillariophyceae; strain MACC/B254) and <em>Prorocentrum minimum</em> (Dinophyceae; strain HYESL63), we investigated responses of lipid biomarkers (sterols and fatty acids (FAs)) to different temperatures (12, 18 and 24℃), nitrogen and phosphorus concentrations and their molar ratios (N:P ratios) of 10:1, 24:1 and 63:1.</p> <p>Algal cells were counted daily with an improved Neubauer hemacytometer (Glaswarenfabrik Karl Hecht GmbH) under a microscope (Olympus CX41). To analyze particulate organic carbon (POC), sterols and FAs, algal cells at steady-state conditions were harvested on pre-combusted GF/F filters (Whatman) after filtering 15-30 mL of cultures depending on cell density in the culture flask and the parameters to be determined. Samples were kept at − 80℃ after filtration.</p> <p>POC was determined by an elemental analyzer (Thermo Flash 2000) (Sharp 1974, https://doi.org/10.4319/lo.1974.19.6.0984). Sterols and FAs were analyzed according to the methods in Eglinton et al. (1996 https://doi.org/10.1021/ac9508513), Galy et al. (2011, https://doi.org/10.1016/j.epsl.2011.02.003) and Zhao et al. (2006, https://doi.org/10.1016/j.orggeochem.2005.08.022). The trimethylsilyl ether derivatives of sterols and fatty acid methyl esters (FAMEs) were analyzed in a gas chromatograph (Agilent Technologies 8890A) equipped with a flame ionization detector, and a HP-1 column (50 m, 0.32 mm i.d., 0.17 μm film; Agilent J&W) and a SP-2560 column (100 m, 0.25 mm i.d., 0.20 μm film; Supelco) for sterol and FAME analysis, respectively.</p> <p>The identification of sterols was performed by gas chromatography-mass spectrometry (GC-MS) analysis at 70 eV using an Agilent 7890B GC (HP-5MS column; 30 m, 0.25 mm i.d., 0.25 μm film; Agilent J&W) connected to an Agilent MSD 5977B mass selective detector (ion source temperature 230℃). Sterols were identified be comparison of the mass spectra of their trimethylsilyl ether derivatives to those of published GC-MS values (Lisboa et al. 1982, https://doi.org/10.1016/0305-0491(82)90281-4; Taipale et al. 2016, https://doi.org/10.3389/fpls.2016.00212), based on the molecular ion and prominent ions. The following sterols were identified: brassicasterol/epi-brassicasterol,and dinosterol. FAs were identified with reference to the standard Supelco 37 component FAME mixture. C-normalized (on a per POC basis; μg mg C-1) and per-cell (pg cell-1) contents of sterols and FAs were presented, and FA proportions (% of total fatty acids (TFAs)) were also reported in the dataset.</p>
Quantification of hair cell number, ribeye b and nuclei in the zebrafish inner ear endorgans
<p>The three otolithic endorgans of the inner ear are known to be involved in sound detection in different teleost fishes, yet their relative roles for auditory-vestibular functions within the same species remain unclear. In zebrafish (<em>Danio</em> <em>rerio</em>), saccule and utricle are thought to play key functions in encoding auditory and vestibular information, respectively, but the biological function of the lagena is not clear. We hypothesized that the zebrafish saccule serves as a <span>primary </span>auditory endorgan, <span>making it more vulnerable to noise exposure</span>, and that lagena might have an auditory function given its connectivity to the saccule and dominant vestibular function of the utricle.</p> <p>In this study, we compared the impact of acoustic trauma (continuous white noise at 168 dB for 24 h) between the sensory epithelia of the three otolithic endorgans. Noise treatment caused hair cell loss in both the saccule and lagena but not in the utricle. This effect was identified immediately after acoustic treatment and did not increase 24 h post trauma. Furthermore, hair cell loss was accompanied by a reduction in presynaptic activity measured based on Ribeye b presence but mainly in the saccule, supporting its main contribution for noise-induced hearing loss.</p> <p>Our findings support the hypothesis that the saccule plays a major role in sound detection and that lagena is also acoustically affected extending the species hearing dynamic range.</p>
