title: Quantitative analysis of 5-FU and its bacterial-derived metabolites by targeted metabolomics (during co-incubation with bacterial strains and Gimeracil)

description: To evaluate the metabolism of 5-FU by multiple bacterial strains and the inhibitory effect of Gim, 40 μM 5-FU and 40 μM Gim were incubated with 4 × 10⁸ CFU/mL of each bacterial strain (<i>C. freundii</i>, <i>P. putida</i>, <i>P. aeruginosa</i>, <i>P. fluorescens</i>, <i>L. reuteri</i>, <i>E. coli</i>, <i>K. pneumoniae</i>, and <i>E. asburiae</i>) in 600 μL of the corresponding medium.The incubation time points were set at 0 h, 6 h, and 24 h (n = 3) and a blank control group was included. At the end of each incubation, 600 μL of ice-cold acetonitrile was added to stop the reaction. After vortexing, 200 μL of each sample was taken, and an equal volume of acetonitrile along with 10 μL of the internal standard 5-Chlorouracil was added. After vortexing, samples were centrifuged at 12,500 rpm for 10 min at 4°C. The supernatant (100 μL) was collected, diluted with four volumes of pure water, vortexed, and centrifuged again. The resulting supernatant was collected for subsequent analysis.The samples were analyzed using liquid chromatography with tandem quadrupole mass spectrometry (LC-MS/MS QQQ) using the AB SCIEX Triple Quad™4500MD. Chromatographic separation was performed using a Kinetex C18 column (2.1 mm × 100 mm, 2.6 μm). The mobile phase consisted of solution A (26.5 mM HCOOH and 1.0 mM NH4OAC in H2O) and solution B (methanol). A flow rate of 0.3 mL/min was used with the following gradient elution profile: 0–0.50 min, 60% A 40% B; 0.5–2 min, 40–85% B; 2–3 min, 85% B; 3–3.5 min, 85–40% B; 3.5–4 min, 40% B. The injection volume injected was consistently set at 10 μL. This assay used multiple reaction monitoring in electrospray negative ionization, and the ions measured for quantitation were as follows: 5-FU, 129.1-&gt;42.1; 5-chlorouracil, 145.1-&gt;42.1; and FBAL, 106.0-&gt;85.9.<b> </b>The retention time for 5-FU and FBAL in the column and gradient was 0.82 and 0.76 min, respectively. The quantitative analysis of 5-FU was performed using an internal standard method with a seven-point calibration curve. Calibration curves for the analytes were obtained using seven calibration standards (100, 200, 500, 1250, 2500, 5000, and 10000 ng/mL for 5-FU and FBAL). Calibration standards were analyzed in duplicate, and curves were constructed using 1/x-weighted linear regression (R² ≥ 0.995). Limit of detection (LOD): 5-FU: 0.1 ng/mL, FBAL: 0.4 ng/mL, both defined at a signal-to-noise ratio (S/N) ≥ 3.

title: Targeted metabolomics analysis of 5-FU after co-incubation with intratumoral bacteria

description: 40 μM 5-FU was incubated with 40 μM Gim (MCE, HY-17469-50mg) and 4×10⁸ CFU/mL of <i>C. freundii</i>, <i>P. putida</i>, <i>P. aeruginosa</i>, <i>P. fluorescens</i>, <i>L. reuteri</i>, <i>E. coli</i>, <i>K. pneumoniae</i>, and <i>E. asburiae</i> in a total volume of 600 μL of NB medium. Three incubation time points were set at 0h, 6h, and 24h (n=3). At the end of each incubation, 600 μL of ice-cold acetonitrile was added to stop the reaction. After vortex mixing, 200 μL of the sample was taken, and an equal volume of acetonitrile along with 10 μL of the internal standard 5-Chlorouracil (Millipore Sigma, 224588) was added. After vortex mixing, the sample was centrifuged at 12,500 rpm for 10 minutes at 4°C. 100 μL of the supernatant was collected, mixed with four volumes of pure water, vortexed and centrifuged, and 100 μL of the supernatant was collected for analysis.The samples were analyzed by liquid-chromatography with tandem quadrupole mass spectrometry (LC-MS/MS QQQ) using the AB SCIEX Triple Quad™4500MD. Chromatographic separation was achieved using a Kinetex C18 column (2.1 mm × 100 mm, 2.6 μm). The mobile phase consisted of solution A: 26.5 mM HCOOH and 1.0 mM NH4OAC in H2O, and solution B: methanol. A flow rate of 0.3 mL/min was used with the following gradient elution profile: 0-0.50 min, 60% A 40% B; 0.5-2 min, 40-85% B; 2-3 min, 85% B; 3-3.5 min, 85-40% B; 3.5-4 min, 40% B. The injection volume injected was consistently set at 10 μL. This assay used multiple reaction monitoring (MRM) in electrospray negative ionization, and the ions measured for the quantitation were: 5-FU: 129.1-&gt;42.1, 5-chlorouracil: 145.1 -&gt; 42.1 and FBAL: 106.0-&gt;85.9.<b> </b>The retention time for 5-FU and FBAL in the column and gradient was 0.82 and 0.76 min, respectively.

title: Ipseity Daily Data

description: At what rate do individuals say they are X?

Begining on 2025-07-08, I surveyed a small random sample of American adults on a daily cadence.  They responded to many items of the form: Does <signifier> describe you today?

The file ipseity-daily-aggregated.csv in this repository contains the aggregated results through 2025-07-28.  The columns are as follows:



signifier - a word, phrase or emoji

yes_count - the number of respondents who answered yes (aggregated all-time).

no_count - the number of respondents who answered no (aggregated all-time).

prevalence_per_10k - an estimate of the prevalence per 10,000.  If we were to survey 10,000 American adults, how many would we expect to respond yes to this signifier?  The number is calculated as yes_count / (yes_count + no_count) * 10,000.

earliest_obs_date - this date represents the first time this particular signifier was ever displayed to a respondent.  Signifiers are chosen with stochasticity from a long list; new signifiers are sometimes added, old signifiers are sometimes deleted, and a signifier may be moved higher or lower in priority for sampling.

latest_obs_date - the date closest to the present date on which signifier was most recently presented to a respondent.

title: Visualization of spin-polarized electronic states by imaging-type spin-resolved photoemission microscopy

description: Harnessing electron spin is crucial in developing energy-saving and high-speed devices for the next generation. In this scheme, visualizing spin-polarized electronic states aids in designing and developing new materials and devices. Spin-resolved photoemission spectroscopy provides information on the spin-polarized electronic states. To investigate the spin-polarized electronic states in microscopic materials and devices, spin-resolved photoemission spectroscopy requires spatial resolution in a sub-micrometer scale. Here we show the imaging-type spin-resolved photoemission microscopy (iSPEM) with an ultraviolet laser developed at the National Institutes for Materials Science (NIMS). Our iSPEM achieves a spatial resolution of 420 nm, drastically improving by more than an order of magnitude compared to conventional spin-resolved photoemission spectroscopy instruments. Besides, the multichannel spin detector significantly reduces the data acquisition time by four orders of magnitude compared to the conventional instruments. The iSPEM machine elucidates the spin-polarized electronic states of sub-micrometer scale materials, polycrystals, device structure samples, and so on, which have yet to be the target of conventional spin-resolved photoemission spectroscopy. We have developed an imaging-type spin-resolved photoemission microscopy machine, realizing quick visualization of the spin-polarized electronic states of materials both in real and momentum spaces.
