Regional Reliability of Combining CT Angiography-source Image and Non-contrast CT in Acute Ischemic Stroke.

CT angiography-source image (CTA-SI) can be used as an effective alternative to diffusion-weighted imaging (DWI) for identifying acute ischemic stroke (AIS). This study investigates the reliability of combining CTA-SI with non-contrast CT (NCCT) for AIS diagnosis, with a focus on how different brain areas affect diagnostic accuracy. Patients with various subtypes of AIS who underwent NCCT, CTA, and DWI from January to December 2022 were included.

Diterpenoid Alkaloid Profiling to Distinguish between the Official Traditional Chinese Medicine (TCM) Fuzi and Adulterant Species Using LC-qToF-MS with Chemometrics.

The lateral roots of , known in Chinese as fuzi, are officially recognized as a materia medica in the and used culinarily to prepare herbal soups. A strategy combining UPLC-qToF-MS analysis of and its intraspecies and interspecies chemometrics study was developed to examine the distribution of marker metabolites. Four diterpenoid alkaloids were recognized to be important markers in fuzi, and another 15 markers were identified to differentiate from adulterant species.
