Marine sponge Hymeniacidon sp. was collected from coastal waters of the East China Sea to isolate symbiotic microorganisms. The resulting sponge-associated actinomycete, Streptomyces carnosus strain AZS17, cultivated in a 20 L volume medium for production bioactive secondary metabolites. Bioassay-guided isolation and purification by varied chromatographic methods yielded two new compounds kijanimicin derivatives, AS7-2 AS9-12. Their structures were elucidated spectroscopy comparison with...
Increasing attention is focused on the down-regulation of miRNAs in cancer process. Nuclear receptor subfamily 2 (NR2F2, also known as COUP-TFII) involved development many types cancers, but its role gastric remains elusive. In this experiment, oncomine and Kaplan-meier database revealed that NR2F2 was up-regulated high expression contributed to poor survival. MicroRNA-27b targeted down-regulated by human tissues cells. The ectopic miR-27b inhibited cell proliferation tumor growth vitro...
With increasing requirements of online monitoring Overhead Transmission Lines (OTL) in smart grids, contact-free measurement technologies have been updated these decades. However, the contactless sensors past research are still limited to application environment like wind deflection. This paper proposes an advanced detection approach with a novel structure enhance possibility implementation and reduce cost. Three pairs probes arranged curved pattern can collect differential voltage signals...
Abstract An acclimation to the changing physicochemical conditions and high amount of Δ 12 ‐unsaturated fatty acids Antarctic Chlorella vulgaris NJ‐7 prompted us speculate about involvement ‐fatty acid desaturases (FAD) in its adaptation extremely unfavorable ambience. A full‐length cDNA sequence, designated CvFAD6, was isolated from C. via RT‐PCR RACE methods. Sequence alignment showed that gene homologous corresponding ‐FAD other eukaryotes. Phylogenetic analysis it grouped with plastidial...
Magnetoelectric (ME) sensors based on piezoelectric/ferromagnetic composites have been investigated extensively due to their resonance-enhanced ME coupling effect and high sensitivity for magnetic field, especially at resonant frequency. However, the drops rapidly when frequency drifts away from resonance, making it unsuitable low-frequency applications. Frequency modulation has proposed as an effective method up-convert of desired signal into mechanical resonance. In this work, we study...
The contact-free measurement of current and voltage technologies are key points to achieve online monitoring tasks in the modern power system, which updated these decades. However, ensuring accuracy a convenient level operation meanwhile is also difficult task that needs be solved advance. Besides, there unidealized situations process application existence measure methods. According principle electric field radiation, this paper proposes non-contact approach based on three pairs dual-probes...
For the application of high-frequency current detection in power systems, such as very fast transient current, lightning partial discharge pulse etc., sensors with a quick response are indispensable. Here, we propose magnetoelectric sensor, which consists PZT piezoelectric ceramic and Metglas amorphous alloy. The proposed sensor is designed to work under d15 thickness-shear mode, resonant frequency around 1.029 MHz. Furthermore, fabricated sensor. A comparative experiment carried out between...
Penicillium herquei isolate GA4 was isolated from the infected Conchocelis of Porphyra yezoensis. A large-scale fermentation using yeast extract sucrose medium and repeated chromatography afforded a new symmetrical urea derivative, hualyzin (1). The structure determined by detailed NMR spectroscopic investigations MS fragmentation analysis.
A series of angucyclinone antibiotics have been isolated from marine Streptomyces sp. strain W007 and identified. Here, a draft genome sequence is presented. The contains an intact biosynthetic gene cluster for antibiotics, which provides insight into the combinatorial biosynthesis produced by streptomycetes.
In multiple-relay wireless power transfer system, the system is usually in a state of detuning caused by variation resonance parameter with various factors. order to solve this phenomenon, dynamic tuning control method based on variable inductor proposed paper. The inductance connected series at transmitting coil end adjust impedance so that achieves purpose reducing loss and improving output voltage gain system. Through simulation experiments, effectiveness structure improve performance...
As the rapid development MEMS (micro-electromechanical systems) packaging technology and magnetoresistance material technology, MR (magnetoresistive) sensors based on effect which can carry out point measurement of magnetic field may change techniques in power systems. The currently available fault location overhead transmission line approaches are mainly traveling-wave technique impedance-based technique. novel approach non-contact is advantageous over traditional that it independent...
Nowadays, the test methods of digital metering system in smart substation are used to and evaluate performance a single device, but these can only effectively guarantee accuracy reliability measurement results device run, it does not completely reflect when each constitutes complete system. This paper introduced shortages existing methods. A system-level method was proposed, feasibility proved by actual test.
