In vitro and in silico anti-inflammatory effect of minor constituents from the roots of Buch.-Ham. ex D. Don.

Vietnamese traditional medicine has utilised the roots of Buch.-Ham. ex D.

and docking and molecular dynamic of antimicrobial activities, alpha-glucosidase, and anti-inflammatory activity of compounds from the aerial parts of .

Twelve compounds were isolated from aerial parts through phytochemical analysis and the genus is the first place where the compounds 4-6 and 11-12 have been found. Based on the ability to inhibit NO production in RAW264.7 cells, compound 2 has demonstrated the strongest anti-inflammatory activity with an IC of 7.

Are high-throughput root phenotyping platforms suitable for informing root system architecture models with genotype-specific parameters? An evaluation based on the root model ArchiSimple and a small panel of wheat cultivars.

Given the difficulties in accessing plant roots in situ, high-throughput root phenotyping (HTRP) platforms under controlled conditions have been developed to meet the growing demand for characterizing root system architecture (RSA) for genetic analyses. However, a proper evaluation of their capacity to provide the same estimates for strictly identical root traits across platforms has never been achieved. In this study, we performed such an evaluation based on six major parameters of the RSA model ArchiSimple, using a diversity panel of 14 bread wheat cultivars in two HTRP platforms that had different growth media and non-destructive imaging systems together with a conventional set-up that had a solid growth medium and destructive sampling.

Amplitude Modeling of Specular Multipath Components for Robust Indoor Localization.

Ultra-Wide Bandwidth (UWB) and mm-wave radio systems can resolve specular multipath components (SMCs) from estimated channel impulse response measurements. A geometric model can describe the delays, angles-of-arrival, and angles-of-departure of these SMCs, allowing for a prediction of these channel features. For the modeling of the amplitudes of the SMCs, a data-driven approach has been proposed recently, using Gaussian Process Regression (GPR) to map and predict the SMC amplitudes.

Undescribed chalcone and stilbene constituents from and their anti-inflammatory effect.

The chemical composition and anti-inflammatory activity of the endemic were investigated for the first time in this study. A phytochemical fractionation of the methanol extract of resulted in the isolation of a new stilbene (bavienside A) and two new chalcone glycosides (baviensides B and C, ). Their structures were elucidated via the interpretation of NMR and HRESIMS spectroscopic data.

Graph analysis of proton conduction pathways in scandium-doped barium zirconate.

Understanding the relationship between the acceptor dopant size and proton conductivity in barium zirconate, BaZrO, is important for maximizing efficiency in this promising fuel cell material. While proton conduction pathways with larger Y and smaller Al defects have been explored, proton pathways with Sc , a defect of comparable size to the replaced ion, have not been investigated using centrality measures, periodic pathway searches, and kinetic Monte Carlo (KMC). Centrality measures in BaScZrO highlight a trapping region by Sc and scattered high centrality regions on undoped planes.

Consumption of antibiotics in a small Pacific island nation: Samoa.

High levels of antibiotic use contribute to development of antibiotic resistance. There is little known about levels of antibiotic use in Samoa, although anecdotally, there are high levels of use, and a strain of methicillin-resistant Staphylococcus aureus may have developed there. The study aimed to gather basic data on levels of antibiotic use in Samoa.
