A FAIR Data Ecosystem for Science of Science.

This poster discusses Automated Research Workflows (ARWs) in the context of a FAIR data ecosystem for the science of science research. We offer a conceptual discussion from the point of view of information science and technology using several cases of "data problems" in the science of science research to illustrate the characteristics and expectations for designers and developers of a FAIR data ecosystem. Drawing from a 10-year data science project developing GenBank metadata workflows, we incorporate the ideas of ARWs into the FAIR data ecosystem discussion to set a broader context and increase generalizability. Researchers can use these as a guide for their data science projects to automate research workflows in the science of science domain and beyond.

Isoflurane reduces the synthesis of surfactant-related protein a of alveolar type II cells injured by H2O2.

The influence of isoflurane (Iso) on the synthesis of surfactant-related protein A (SP-A) of alveolar type II (AT II) cells in primary culture and after injury by H2O2 was investigated. AT II cells were isolated and purified from adult Sprague-Dawley rats and used for experiments after 32 h in primary culture. The cell cultures were randomized to six groups (n = 8 in each group): control group (no treatment), 0.28 mM Iso group, 2.8 mM Iso group, 75 microM H2O2 group, 75 microM H2O2 + 0.28 mM Iso group, and 75 microM H2O2 + 2.8 mM Iso group. Each group was continuously incubated for 3 h after administration of Iso and/or H2O2. The intracellular SP-A and the SP-A of the culture medium were measured with an enzyme-linked immunosorbent assay (ELISA). Iso significantly decreased the intracellular SP-A content and that of the culture medium, and aggravated the decrease of SP-A content induced by H2O2. These findings suggest that Iso itself may decrease SP-A synthesis of AT II cells in vitro, and aggravate the damage to AT II cells under peroxidation conditions.

Effect of isoflurane on proliferation and Na+,K+-ATPase activity of alveolar type II cells injured by hydrogen peroxide.

The influence of isoflurane (Iso) on proliferation and Na+,K+-ATPase activity of alveolar type II cells (ATII cells) injured by hydrogen peroxide (H2O2) was investigated. ATII cells isolated and purified from adult Sprague-Dawley rats were randomly divided into six groups: control group, 0.28 mM Iso group, 2.8 mM Iso group, 75 microM H2O2 group, 75 microM H2O2 + 0.28 mM Iso group, and 75 microM H2O2 + 2.8 mM Iso group. After primary culture for 32 hours, the proliferation of ATII cells was detected by MTT assay, and after culture for 24 hours the activity of Na+,K+-ATPase and lactate dehydrogenase (LDH) in the cells, and malonaldehyde (MDA) content of the culture medium, were measured by colorimetry. It was found that 0.28 mM and 2.8 mM Iso had no effect on the proliferation of ATII cells (p > 0.05), but 75 microM H2O2 inhibited their proliferation (p < 0.05) compared with untreated controls; 0.28 mM and 2.8 mM Iso significantly decreased Na+,K+-ATPase activity of ATII cells compared with untreated control cells (p < 0.05), and 75 microM H2O2 markedly decreased Na+,K+-ATPase activity of ATII cells (p < 0.01) with untreated control cells. 0.28 mM and 2.8 mM Iso aggravated the decrease of Na+,K+-ATPase activity induced by H2O2. Iso had no effect on LDH activity and MDA content of the culture medium of normal ATII cells, but significantly increased LDH activity and MDA content of the culture medium of ATII cells injured by H2O2. These findings suggest that Iso itself may decrease the activity of Na+,K+-ATPase of ATII cells in vitro and further damage the cells' function under peroxidation conditions, but has no effect on the proliferation of ATII cells.
