Feasibility of an artificial intelligence system for tumor response evaluation.

Purpose: The objective of this study was to evaluate the feasibility of using Artificial Intelligence (AI) to measure the long-diameter of tumors for evaluating treatment response.

Methods: Our study included 48 patients with lung-specific target lesions and conducted 277 measurements. The radiologists recorded the long-diameter in axial imaging plane of the target lesions for each measurement.

Further Chromone Alkaloids from Schumanniophyton magnificum.

Six further alkaloids have been isolated from the water-soluble fraction of the ethanolic extract of SCHUMANNIOPHYTON MAGNIFICUM Harms. Two of these are the known compounds trigonelline and rohitukine but the other four compounds are novel. Two of these, named schumagnine and N-methylschumagnine, consist of the chromone noreugenin linked to piperidine-related moieties whilst the other two are quaternary amines, the N-methyl analogues of schumanniophytine and isoschumanniophytine.

Novel Chromone Alkaloids from Schumanniophyton magnificum.

Six chromone alkaloids were isolated from the root bark of SCHUMANNIOPHYTON MAGNIFICUM Harms. Three of these were identified as the known alkaloids schumanniophytine, schumannificine and N-methylschumannificine. The other three alkaloids are novel and were named isoschumanniophytine, anhydroschumannificine and N-methylanhydroschumannificine.
