The phytochemical investigation of the leaves and the roots of Suregada procera afforded the new ent-abietane diterpenoid sureproceriolide A (1) along with the known secondary metabolites 8,14β:11,12α-diepoxy-13(15)-abietane-16,12-olid (2), jolkinolide A (3), jolkinolide E (4), ent-pimara-8(14),15-dien-19-oic acid (5), sitosterol (6), oleana-9(11):12-dien-3β-ol (7), and oleic acid (8). Their structures were elucidated by NMR spectroscopic and mass spectrometric analyses, and the structure of jolkinolide A (3) was confirmed by single-crystal X-ray diffraction analysis. Sureproceriolide A (1) showed modest activity against the Gram-positive bacterium Staphylococcus lugdunensis (MIC = 31.

The structures of the isolates were elucidated by using NMR, ECD, and HRESIMS data analyses. Among the isolated compounds, gloverinol B (), gloveriflavan B (), and 1-(2,4-dihydroxyphenyl)-3-hydroxy-3-(4-hydroxyphenyl)-1-propanone () were the most active against , with MIC values of 9.

- The review investigates the diagnostic accuracy of the Sysmex hematology analyzer for malaria detection, comparing it to the traditional light microscopy method.
- Data was collected from multiple electronic databases, with a total of 15 studies analyzed to assess sensitivity and specificity, showing high accuracy (95% sensitivity and 99% specificity) for the Sysmex analyzer.
- The results indicate that while the Sysmex hematology analyzer shows excellent diagnostic capabilities, there was notable heterogeneity among the studies in the meta-analysis.
Three new (-) and six known rotenoids (-), along with three known isoflavones (-), were isolated from the leaves of ssp. . A new glycosylated isoflavone (), four known isoflavones (-), and one known chalcone () were isolated from the root wood extract of the same plant.
