The rhizosheath, a layer of soil grains that adheres firmly to roots, is beneficial for plant growth and adaptation to drought environments. Switchgrass is a perennial C4 grass which can form contact rhizosheath under drought conditions. In this study, we characterized the microbiomes of four different rhizocompartments of two switchgrass ecotypes (Alamo and Kanlow) grown under drought or well-watered conditions via 16S ribosomal RNA amplicon sequencing. These four rhizocompartments, the bulk soil, rhizosheath soil, rhizoplane, and root endosphere, harbored both distinct and overlapping microbial communities. The root compartments (rhizoplane and root endosphere) displayed low-complexity communities dominated by Proteobacteria and Firmicutes. Compared to bulk soil, Cyanobacteria and Bacteroidetes were selectively enriched, while Proteobacteria and Firmicutes were selectively depleted, in rhizosheath soil. Taxa from Proteobacteria or Firmicutes were specifically selected in Alamo or Kanlow rhizosheath soil. Following drought stress, Citrobacter and Acinetobacter were further enriched in rhizosheath soil, suggesting that rhizosheath microbiome assembly is driven by drought stress. Additionally, the ecotype-specific recruitment of rhizosheath microbiome reveals their differences in drought stress responses. Collectively, these results shed light on rhizosheath microbiome recruitment in switchgrass and lay the foundation for the improvement of drought tolerance in switchgrass by regulating the rhizosheath microbiome.A method based on high-performance liquid chromatography and Fourier transform-ion cyclotron resonance mass spectrometry was developed to control the quality of Semen Hoveniae. First, the chromatographic fingerprint was established in combination with the chemometrics methods such as similarity analysis, cluster analysis, principal component analysis, and orthogonal partial least squares discriminant analysis to discover the qualitative markers. Then, an high-performance liquid chromatography mass spectrometry method was developed to identify the chemical constituents in Semen Hoveniae. Moreover, the content of dihydromyricetin and dihydroquercetin in Semen Hoveniae were determined by high-performance liquid chromatography. AT-101 acetic acid As a result, nine common peaks were assigned in the fingerprints and the similarity of the 13 batch samples varied from 0.425 to 0.993, indicating an obviously different quality. Dihydromyricetin and dihydroquercetin were the main qualitative markers to differ the quality of Semen Hoveniae. Meanwhile, a total of 21 chemical compounds were characterized by high-performance liquid chromatography mass spectrometry and six of them were identified by comparing with information of reference standards. Finally, the content of dihydromyricetin and dihydroquercetin in 13 batch samples varied from 0.824 to 7.499 mg/g and from 0.05941 to 4.258 mg/g , respectively. In conclusion, the methods developed here will provide sufficient qualitative and quantitative information for the quality control of Semen Hoveniae.
Iron deficiency anaemia (IDA) and anaemia of chronic disease (ACD) are common causes of anaemia with similar clinical and laboratory features. IDA is caused by low iron stores while ACD is due to iron-restricted erythropoiesis occurring in inflammatory states. Differential diagnosis requires analysis of multiple biochemical and haematological parameters. IDA can occur simultaneously to ACD (mixed aetiology). It is essential that true iron deficiency is identified, as these patients will require iron therapy. This preliminary study investigated whether hepcidin, the master regulator of iron homeostasis, in conjunction with reticulocyte haemoglobin equivalent (RetHe) has the potential to differentiate IDA from ACD, and to exclude IDA in patients with mixed aetiology.

Hepcidin concentration (measured using a commercially available ELISA method), RetHe, and iron parameters along with C-reactive protein (CRP) were analysed in 77 Gastroenterology patients with anaemia in a secondary care setting.

Receiver operator characteristic (ROC) analysis showed that hepcidin at an optimal cut-off concentration of <6ng/ml could identify IDA with a sensitivity and specificity of 88.9% and 90.6% respectively and could distinguish ACD from IDA with both a sensitivity and specificity of 100% at a cut-off of >46ng/ml. Identifying true IDA in mixed aetiology patients could be achieved by RetHe analysis and applying an optimal cut-off of <30pg.

Hepcidin, in conjunction with RetHe, offers a new simplified diagnostic pathway for differential diagnosis of IDA and ACD, thereby reducing the diagnostic turnaround time and allowing appropriate treatment of patients with a true iron deficiency.

This study maps the funding relationships between foundations, ENGOs and think tanks in Canada and considers the implications for environmental politics. We examine foundation funding for different strains of environmental politics and policy-planning and consider how ENGOs and think tanks are clustered as communities within a foundation-centred support network. Of particular interest are 'clean growth' ENGOs that have emerged as key proponents of business-friendly approaches to the climate crisis. We find that the ENGOs receiving large grants tend to be conservationist while the think tanks tend to be conservative. Communities in the network are divided between several clusters of corporate and family foundations supporting conservative think tanks, clean growth ENGOs and conservationist ENGOs, and a segment of the network in which one municipal and several family foundations, support more social-ecological organizations, thereby facilitating more transformative visions and policies. Although few in number, clean growth organizations tend to receive giant donations, in some cases from corporate foundations aligned with the fossil-fuel sector. Recent adoption of clean growth as governmental policy and its embrace within philanthropic missions could reshape the environmental field towards 'clean growth', as ENGOs seek funding and legitimacy.
