    Sedimentary pigment, sterol and stanol data for the Holocene record of Lake Uddelermeer (The Netherlands) (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-17
    Description: This dataset provides geochemistry data for the Holocene sediment sequence retrieved from Lake Uddelermeer (The Netherlands) in 2012. Concentrations of sedimentary pigments, fossil sterols and stanols as well as elemental (C, N) measurements are presented against both depth (cm) and age (cal yr. BP). A total of 92 samples were analysed for C, N and sedimentary pigment content; a subset of 30 samples was analysed for sterol and stanol compounds. The data provides an insight in the natural variability of the lake ecosystem and has been used to identify the anthropogenic drivers of the change to the turbid conditions that currently characterize this lake. Cores were retrieved from the centre of the lake using a 3-m long handheld piston corer deployed from a floating coring platform during field work in April and May 2012. Samples were obtained from splits of the core and processed in the laboratory of the University of Amsterdam (the Netherlands) using standard protocols, including the use of high performance liquid chromatography (HPLC) to determine sedimentary pigment concentrations and full scan as well as selective ion monitoring (SIM) gas chromatography-mass spectrometry (GC–MS) analysis to determine sterol and stanol concentrations.

    Lake Uddelermeer: Late-glacial and Holocene pollen, chironomid & loss-on-ignition data (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-17
    Description: This dataset provides palaeoecological and sedimentological data for the Late-glacial and Holocene sediment sequence retrieved from Lake Uddelermeer (The Netherlands) in 2012. Counts of pollen and chironomids are presented against both depth (cm) and age (cal yr. BP), and a loss-on ignition record is presented against depth. A total of 110 samples were analysed for their pollen content; a subset of 32 samples was analysed for sterol and stanol compounds. A total of 1412 samples were analysed for their organic content, approximated through loss-on-ignition. The data provides information on changes in the local and regional vegetation, changes in the within-lake ecosystem and changes in minerogenic input into the lake. The dataset has been used to identify Holocene lake level changes at the site. Cores were retrieved from the centre of the lake using a 3-m long handheld piston corer deployed from a floating coring platform during field work in April and May 2012. Samples were obtained from splits of the core and processed in the laboratory of the University of Amsterdam (the Netherlands) using standard protocols. Individual pollen grains and chironomid head capsules were identified using high-power microscopy, and loss-on-ignition was determined using combustion in a 550C oven.

    Notes: Abstract. A mild increase in temperature that does not exert an effect on tolerance development or synthesis of heat shock proteins (Hsps) in control cells can stimulate these processes when applied to cells that have previously been heat shocked. To study the underlying mechanism of this effect, H9c2 cells were stably transfected with the gene encoding firefly luciferase (Luc). Heat-shock-induced inactivation of Luc and its subsequent reactivation is frequently used as a model for cellular protein denaturation and renaturation. Luc reactivation was determined following a damaging heat shock (43 or 44 °C for 30 min) in cells that were subsequently exposed to either control temperatures (37 °C) or various mild hyperthermic conditions (from 38.5 to 41.5 °C for 1 h). To prevent changes in Luc activity consequent to new synthesis of Luc, Luc reactivation was monitored in the presence of cycloheximide, an inhibitor of protein synthesis. The results showed that reactivation of Luc was inhibited when heat-treated cells were post-treated under mild hyperthermic conditions. The observed increase in Hsp synthesis under mild hyperthermic post-heat shock conditions therefore appears to be the result of an increase in the period during which denatured proteins are present. In addition, we studied Luc reactivation in the absence of protein synthesis inhibitors. This condition led to much higher Luc activity. By estimating half-life times of Luc, the contribution of new Luc synthesis in this recovery could be determined, and only partially explained the observed increase in Luc reactivation after heat shock. Thus the synthesis of other proteins must be important for the renaturation of heat-damaged proteins.
