Thirty compounds including 13 new phenolic glycosides (1-6, 9-15) and 17 known aromatic (7-8, 16-30) were isolated from the roots of Wrightia pubescens. The structures established by extensive NMR spectroscopic data analysis as well chemical derivatization method. evaluated for their hepatoprotective activities using cell model acetaminophen (APAP)-induced HepG2 cells. results indicated that (2, 4, 5, 7, 8, 11, 13) pretreatment enhanced cells viability reduced levels aspartate...
Abstract Real‐time, high‐precision X‐ray imaging is of critical importance in a wide range applications, from medical diagnostics to security screening. While lanthanide luminescent materials are among the most commonly used scintillators, achieving combination large‐area scalability, rapid response, and optimal performance remains challenging. Herein, perovskite‐inspired cerium halide nanocrystal scintillator presented with remarkable photoluminescence quantum yield approaching unity fast...
Soybean is a critical agricultural product in China, with domestic production unable to satisfy the substantial demand, leading huge reliance on imports. To support scientific formulation of policies and optimization planting structures, we developed high-resolution annual soybean yield dataset for China (2001–2020), ChinaSoyYield1km. This was generated by applying ensemble learning algorithms spatial decomposition comprehensive set multi-source data, including climate variables, remote...
Reactive oxygen species and subsequent oxidative stress are reported to play important roles in chronic metabolic diseases. Plant-derived polyphenols, especially food-derived phenolics, have attracted a lot of attention due their potential usage against stress-related The leaf Psidium guajava (known as guava) is regarded good resource polyphenols its products commercially available Japan functional foods multiple metabolism disorders. In the course finding novel with antioxidative activities...
Improving structure of soils found at 0–5 cm depth, and increasing the thickness biological soil crusts are both associated with sand dune revegetation‐stabilization in arid northwestern China. Since 1956, research on stabilization has included use straw chequer‐boards to facilitate development structure. One method gauge degree is compare undisturbed hydraulic properties, including water retention [ h (θ)] conductivity K ( )] functions, properties from stabilized sites different ages. This...
To discover ulcerative colitis (UC) treatment agents, 28 oleanane-type triterpenoid saponins (1–28) including three new saponins, pulsatillosides P-R (1–3), were isolated from Pulsatilla chinensis. The could observably ameliorate UC by improving the intestinal epithelial cell barrier and flora in vivo. structure–activity relationship indicated that oligosaccharide chain at C-28 was essential for their anti-UC activities; methyl group C-23 site of triterpene showed important effects on...
Eleven metabolites, six echinosporins (1-6), four dibenzoyls (7-10), and an aromatic compound (11), were isolated from the fermentation broth of lichen-associated Amycolatopsis hippodromi. The structures new compounds (1-5, 8-11) elucidated by comprehensive spectroscopic analysis including data experimental calculated ECD spectra. Amycolasporins A-C (1-3) demonstrated antibacterial activities against Bacillus subtilis, Staphylococcus aureus, Escherichia coli with MIC values 25 or 100 μg/mL....

Abstract Four new barringtogenol C-type triterpenoid saponins, namely acerplatanosides A – D (1–4), along with 22 known compounds (5–26), were isolated from the stem bark of Norway maple (Acer platanoides). Their structures elucidated on basis comprehensive spectroscopic analyses and chemical hydrolysis. This is first report saponins maple. Compounds 1, 3, 4 showed cytotoxicity against human cancer cell lines IC50 values ranging 9.4 to 39.5 µM.
The database security is usually connected with the network security. This passage will discuss and study resolution of threat model based on STRIDE. B/S architecture used to illustrate that what this be faced with. Aimed at threats, responding resolutions are also given build more safe credible system.

Finally, function class-real time-query given as test cases, result proving being content...
Abstract This study discusses the theory behind passive treatment systems for controlling acid drainage of Meirama mine and illustrates how this approach can be applied to obtain necessary water quality allow discharge into Barcés River, which is primary tributary drinking supply Cercebre Reservoir (Spain). Characterization analysis was carried out 13 sampling sites, with a total 52 tests 780 determinations analyses. Passive have been monitored over 27 days, 186 samples taken, plus 1914 The...
Mansouramycin derivatives caused S phase cell cycle arrest and induced apoptosis in MBA-MB-231 cells，and a piperazine moiety introduced into the amino group at C-7 could improve activities of mansouramycins.
The educational administration management system works as an important component of campus system. At the same time, attendance plays role in it, which is a new field that few studies have involved in. Owing to self-description and flexibility XML, XML will become technology In order fill gap make it good extensibility different platforms, this paper designs applies Web service into its development. test for given, with testing results showing functionality could meet needs. Finally, future...
The traditional JavaEE existed in large enterprise web applications, uses Enterprise JavaBean as the core component, which results high coupling and low scalability. Based on three kinds of opening source frameworks are Struts2, Spring Hibernate (SSH), this paper proposes an integrated application architecture for silk relic information system. presented not only meets requirements aspects maintainability, scalability code reuses, but also speeds up system development. Furthermore, SSH...
Abstract Wenying Lake in Datong, China, has been drying for the last several years. Analysis of standard penetration test data revealed that a missing waterproof layer silt soil and silty clay south part lake, resulting from frequent flood flushing, was responsible water loss lake. Accordingly, 6.7 × 10 5 m 2 geosynthetic liner (GCL) used May 2010 to repair area sediment exhibiting leakage, equivalent 15.6% total lake bottom area. Approximately 4.1 6 3 floodwater then diverted upstream...
Sinking artificial fish-simulated baits have been used widely in sea fishing. However, at present, there isn't a rational solution for plumbic block locating sinking baits. This paper analyzes the force of seawater, finds parameters that influence balance bait and put forward mathematical model bait, which is able to be all kinds And gain algorithm Via implementing by Matlab do some experiment, it proved feasible.
Security and privacy is a big problem that feazing computer researchers all along. In the pervasive computing, because traditional methods of user authorization access control are no longer adapted, security becomes much more difficult to ensure. This paper proposes dynamic trust model based on P2P. this we call PDTM. The adopts technique automated negotiation. Compared with those models existing, our can fit environment computing even more. And it resolve problems well entities' ubiquitous...
Ontology is a model tool, which used to describe the concepts of information systems in terms meaning and knowledge arrangement.
