Spatial transcriptomics has revolutionized the study of gene expression within tissues, while preserving spatial context. However, annotating spatial spots' biological identity remains a challenge. To tackle this, we introduce Pianno, a Bayesian framework automating structural semantics annotation based on marker genes.

PBL height (PBLH) determines the vertical extent to which the most pollutant effectively disperses and is a key argument in pollution study. In this study, we quantitatively evaluate aerosol radiation effect on PBL, as well as assessment of surface cooling effect and atmosphere heating effect.
View Article and Find Full Text PDFA neuroinflammatory response is commonly involved in the progression of many neurodegenerative diseases. Potassium 2-(1-hydroxypentyl)-benzoate (PHPB), a novel neuroprotective compound, has shown promising effects in the treatment of ischemic stroke and Alzheimer׳s disease (AD). In the present study, the anti-inflammatory effects of PHPB were investigated in the plasma and brain of C57BL/6 mice administered a single intraperitoneal (i.

The new compounds were identified as (9)-moracin P 3'--α-l-arabinopyranoside (), (9)-moracin P 9--β-d-glucopyranoside (), (9)-moracin P 3'--β-d-glucopyranoside (), and (9)-moracin O 10--β-d-glucopyranoside () based on the spectroscopic interpretation and chemical analysis. Three benzofuran-type stilbenes, moracin O (), R (), and P () showed significant neuroprotective activity against glutamate-induced cell death in SK-N-SH cells.

Medicines currently available for AD treatment are only for improving the cognitive symptoms, but not able to stop or delay disease progression.

These compounds comprise seven different structural types. All structures were determined by NMR spectroscopic methods and both experimental and calculated electronic circular dichroism (ECD) spectra.
