Molecular Circuit Linking Abscisic Acid Signaling to Tanshinone Production Uncovered

Salvia miltiorrhiza, also known as Danshen, is a highly regarded traditional Chinese medicine widely used for treating cardiovascular and cerebrovascular diseases. Its medicinal properties are largely attributed to tanshinones-a group of more than 40 diterpenoid quinone compounds, including tanshinone I, tanshinone IIA, and cryptotanshinone, which predominantly accumulate in the plant's roots.

Optical Metabolic Imaging Profiles Single-Cell Metabolic Fitness in Blood Without Dye Labeling

A routine blood sample contains a diverse collection of immune cells that can reveal important clues about health and disease. These cells, known as peripheral blood mononuclear cells (PBMCs), are widely used to study infections, autoimmune disorders, cancer, and the immune system's response to treatment.

Wearable Microneedle Sensor Enables In Vivo Bioanalysis of Cardiac Biomarkers

Researchers developed a microneedle electrochemiluminescence device that measured cardiac troponins in interstitial fluid at 30-minute intervals and detected cTnI down to 21.3 fg/mL in artificial interstitial fluid. In 15 rats and 1 pig, researchers recorded biomarker trends broadly consistent with serum ELISA results, although the wired, single-target prototype has not been tested in humans.

Deep-Learning Holography Detects Elusive Circulating Tumor Cells in Prostate Cancer

Researchers combined microfluidic enrichment, AI-assisted holography, and fluorescence profiling to identify circulating tumor cell candidates in 13 men with metastatic castration-resistant prostate cancer and 8 healthy donors. The platform found higher median candidate counts in patients, while nearly two-thirds of PSMA-positive candidates lacked EpCAM, suggesting EpCAM-dependent assays could miss some cells.
