title: Coronary angiography investigation before permanent pacemaker implantation is not associated with mortality in a historical cohort with a 1-year follow-up (CorInPace)

description: The datas investigates the impact of coronary artery disease (CAD) screening via invasive coronary angiography (CAG) on patient outcomes who require urgent pacemaker implantation due to symptomatic bradyarrhythmias. The study compares mortality, hospital readmission rates, and CAD prevalence between patients who underwent CAG and those who did not, revealing that while CAG led to longer hospital stays and delayed pacemaker implantation, it did not significantly affect overall mortality or combined outcomes of death and readmission within one year.

title: Supplementary Material: Key Considerations for Sustainable Separations in Countercurrent Chromatography

description: Abstract: Countercurrent chromatography (CCC) is a liquid-liquid separation technique in which compounds are separated based on partitioning between two immiscible phases. Besides having inherent advantages –  high loading capacity,  easy scale-up, and sample recovery with no chemical degradation – that position CCC as an alternative to conventional chromatographic methods, it can also be sustainable, especially when methodologies are optimised, including the use of eco-friendly solvents, high sample loading, and solvent recycling. This review highlights the green potential of CCC by integrating green chemistry principles through low solvent consumption, reduced waste, and the use of bio-based solvents, such as aqueous two-phase solvent systems and deep eutectic solvents, to align CCC with sustainable chromatographic approaches. Also, the technique's ability to recycle solvent phases and process crude extracts with minimal sample preparation boosts its environmental benefits. Despite these advantages, several challenges limit the widespread adoption of CCC, particularly in industrial settings. Patent analysis indicates that while CCC is commonly used to purify natural products, its role in sustainability-driven innovations remains relatively limited. The selection of biphasic solvent systems is a critical bottleneck, often requiring extensive experiments, which can result in excessive solvent use. Advances in computational methods have improved the selection of solvent systems, allowing for a more resource-efficient approach. By modeling phase interactions, these computational tools can predict partition coefficients and optimize solvent compositions, consequently reducing experimental waste. Future research should focus on integrating CCC into large-scale sustainable workflows to enhance its environmental viability in natural product chemistry.

The data set reports on long term atmospheric observations (chemical composition of the aerosol, physical properties of the aerosol and surface ozone, and particle concentration) at the Air Chemistry Observatory (Neumayer III, Antarctica) between 1 January 2023 and 31 December 2023, measured about 5-7 m above ground. Data are typically available in 60 sec resolution.

title: Experimental phosphate limitation in Nodularia spumigena CCY9414

description: Nodularia spumigena is a toxic, filamentous cyanobacterium capable to fix atmospheric nitrogen, which is often dominating cyanobacterial bloom events in the Baltic Sea and other aquatic systems worldwide. Phosphate (P) limitation has been considered as one environmental parameter that is somehow promoting the establishment of cyanobacterial mass developments. In the present study, we analyzed the response of Nodularia spumigena strain CCY9914 towards strong phosphorus limitation in an experimental approach. Pre-experimental and experimental incubations were performed at the Department of Plant Physiology (University of Rostock, Germany). Specifically, cultures were incubated under P-replete and P-deplete conditions for 21 days. The P-replete medium was composed as follows: 33% ASNIII and 67% BG11 medium mixture (as described by Hagemann et al., 2019), with 0.02 g L-1 K2HPO4 in the modified ASNIII (Rippka et al., 1979) and 0.00078 mg L-1 K2HPO4 in BG11 medium modified with 20 mM TES buffer to pH 8 (Rippka et al., 1979). Conversely, the P-deplete medium did not contain any additional P. Samples were collected after 3 hours (day 0), 7, 14 and 21 days from the start of the experiment to assess the variation of the following physiological parameters: biomass increase estimated by dry weight measurements and polyphosphate accumulation measured according to Martin et al. (2014). Additionally, ortho-phosphate and ammonium concentrations were measured in the medium to assess nutrient conditions during the course of the experiment. The experiment was repeated two times. During the second iteration of the experiment, samples from d7 and d14 were used for differential gene expression analysis (RNA-seq data available on Gene Expression Omnibus (GEO) accession GSE213384).

title: Phytoplankton pigment and phytoplankton group chlorophyll-a concentrations during POLARSTERN cruise PS131 from North Sea to East Greenland Sea in 29. June to 3. August 2022 from HPLC analysis of water

description: Phytoplankton pigments were determined in the water surface (from 0 to 11 m depth) of a transect from the North Sea to East Greenland Sea and back during RV Polarstern expedition PS131 from 29 Jun to 3 Aug 2022. Water samples were collected from CTD Niskin bottles at five to six different depths from the upper 100 m at CTD stations and from underway sampling. Between 0.4 to 3.5 L of each seawater sample was filtered through Whatman GF/F filters. The sample filters were then shock‐frozen in liquid N2 and kept at −80 °C until analysis. High Pressure Liquid Chromatography (HPLC) was performed to quantify various phytoplankton pigments (see Table 1 in Taylor et al. 2011) following the method of Barlow et al. (1997) that was adjusted to our temperature‐controlled instruments as detailed in Alvarez et al. (2022). Data were used to analyse the Fram Strait phytoplankton community composition dynamics in Bracher et al. (submitted to DSR-II).

title: Rock magnetic properties of petrologically representative IRD particles in sediment core GeoB18530-1

description: In order to determine the bulk magnetic impact of all 22 classified IRD lithologies, the specific petromagnetic properties of each were investigated in detail. In order to represent host rock composition as good as possible and to meet the magnetometric sensitivity requirements, the largest available IRD particles (dropstones) of each IRD species were selected, that were typically of granule or pebble size. Where such large particles were not available, several petrologically similar coarse sand-sized particles were combined in one sample. Great care was taken in sample preparation and sample holder correction to reach reliable values even for small and low-magnetic samples. In addition to magnetic properties, we also provide averaged IRD counts of HLs and in ILs for each IRD lithology.
