Potassium Iodide (KI): Research Facts and Limits
2026-08-18
Potassium Iodide, also written KI, supplies iodide for thyroid hormone synthesis and can support radioactive iodine thyroid blocking under appropriate public-health guidance. The B2008 research product has documented solubility, storage, and purity specifications, but the cited immunotherapy study does not establish KI as an immunotherapy component.

Tolazoline, KATP Channels, and Insulin Release
2026-08-17
The 1992 Br. J. Pharmacol. study showed that Tolazoline and related imidazoline antagonists increase insulin release primarily by inhibiting ATP-sensitive K+ channels in pancreatic β-cells, rather than simply by blocking α2-adrenoceptors. Its combined use of 86Rb efflux, whole-cell patch clamp, and pharmacological challenge assays provides a useful framework for interpreting insulin secretion modulation in islet experiments.

PSPro Maps Single-Cell Spatial Proteomes
2026-08-13
Mao and colleagues introduce PSPro, a proximity-labeling workflow that captures cell-type-associated proteomes directly from complex tissue slices with sub-micrometer spatial resolution. Its application to pancreatic tumor and spleen tissue demonstrates all-at-once profiling of ten cell types and exposes spatial heterogeneity that is difficult to resolve with conventional region-based proteomics.

Dual-Action Inhibitors Reprogram p38α Dephosphorylation
2026-08-09
The reference preprint shows that selected p38α MAP kinase inhibitors do more than suppress catalytic activity: they stabilize an activation-loop conformation that accelerates dephosphorylation by the phosphatase WIP1. Biochemical assays and X-ray structures connect inhibitor binding, phospho-threonine accessibility, and kinase inactivation, suggesting a route to more durable and selective kinase control.
