Preliminary data on microcharacters and chromosome number in Tornabenea species (Apiaceae) from Cape Verde islands
Tornabenea is a small Apiaceae genus that is endemic to the Cape Verde Islands. Its species differentiation is based just on a
few macromorphological characters: leaf shape, number and shape of umbel bracts and mericarp ribs. These characters vary
within each species and show high plasticity. Thus, in recent taxonomic data of the genus, there are different viewpoints as to
the number of species. Here, in order to improve the taxonomy of the genus, microcharacters of the vegetative and
reproductive structures of three taxaâT. insularis, T. annua and T. tenuissimaâhave been examined. The shape and
arrangement of hairs on the surface of the mericarps, and the presence and structure of starch grains are the only different
microcharacters noted in T. insularis and T. annua. Chromosome number of the latter two species is 2nŒ18. Our
preliminary results disagree with the existing classifications of the genus Tornabenea. In fact, they do not lead to a clear
separation between T. insularis and T. annua. By contrast, it is easy to distinguish between these species and T. tenuissima,
which possesses more peculiar microcharacter

Accuracy of citrulline, I-FABP and d-lactate in the diagnosis of acute mesenteric ischemia
Data availability:
Research data are not shared.Supplementary Information oi available online at: https://www.nature.com/articles/s41598-021-98012-w#Sec14 .Early diagnosis of acute mesenteric ischemia (AMI) remains a clinical challenge, and no biomarker has been consistently validated. We aimed to assess the accuracy of three promising circulating biomarkers for diagnosing AMIâcitrulline, intestinal fatty acid-binding protein (I-FABP), and D-lactate. A cross-sectional diagnostic study enrolled AMI patients admitted to the intestinal stroke center and controls with acute abdominal pain of another origin. We included 129 patientsâ50 AMI and 79 controls. Plasma citrulline concentrations were significantly lower in AMI patients compared to the controls [15.3 ÎŒmol/L (12.0â26.0) vs. 23.3 ÎŒmol/L (18.3â29.8), pâ=â0.001]. However, the area under the receiver operating curves (AUROC) for the diagnosis of AMI by Citrulline was low: 0.68 (95% confidence intervalâ=â0.58â0.78). No statistical difference was found in plasma I-FABP and plasma D-lactate concentrations between the AMI and control groups, with an AUROC of 0.44, and 0.40, respectively. In this large cross-sectional study, citrulline, I-FABP, and D-lactate failed to differentiate patients with AMI from patients with acute abdominal pain of another origin. Further research should focus on the discovery of new biomarkers.Grants from MSD-Avenir and APHP funded the SURVIBIO study; Alexandre Nuzzo received Ph.D. Grants from âFondation de l'Avenirâ and the French Gastroenterology Society (SNFGE)
