Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Lan Jin, Jinfeng Sun, Mei Jin, Chunshi Jin, Shengbao Diao, Wei Zhou, Gao LiAbstractA previously undescribed secoiridoid aglycone, syrinretin (1), together with a reported secoiridoid aglycone (2), three phenylethanoids (3, 4 and 6), phenolic acid (5) and two coumarins (7 and 8) were isolated from the stem bark of Syringa reticulata (Bl.) Hara (Oleaceae). The structures were elucidated from 1D and 2D NMR spectroscopic data by comparison with reported literature values. Compound 1 and compounds 2, 4–6 and 8 were identified in the genus Syringa for the first time. The chemotaxonomic significance of these compounds is also discussed.Graphical abstract
Authors: Zhylkaidarova A, Kaidarova D, Batyrbekov K, Shatkovskaya O, Begimbetova D Abstract We carried out an analysis of the total incidence of colon cancer throughout Kazakhstan. Retrospectively, according to the regional reports on endoscopic screening, the study showed an increase in the age-related incidence of colorectal cancer (CRC) cases from 2004-2008 to 2009-2014. The peak of morbidity in both periods was noted in the age category of>70 years. The indicators of the territorial distribution of CRC incidence make it possible to divide the regions into areas with low or high rates of CRC. Specific indicat...
Conclusions: The transduodenal approach for obtaining samples from solid lesions using a 19-G flexible needle seems feasible and accurate. PMID: 32447874 [PubMed - as supplied by publisher]
