[Exploration on origin of Simiao Yong'an Decoction].

Simiao Yong'an Decoction is composed of Lonicerae Japonicae Flos, Scrophulariae Radix, Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizome, which was chosen as one of the 100 classic prescriptions in Catalogue of Ancient Classics Prescription(the first batch). Through tracing to the source, It was found that the Simiao Yong'an Decoction(but not named) originated from the Shi Shi Mi Lu, and was later cited by books such as Ancient and Modern Book Integration-Full Record of Medical Department and New Edition of Useful Prescriptions. Literature shows that this prescription was not named until first reported in the Effect of Traditional Chinese Medicine on Arterial Embolism Gangrene in 1956 by a journalist LYU Min.

Transcriptome sequencing of Tessaratoma papillosa antennae to identify and analyze expression patterns of putative olfaction genes.

Studies on insect olfaction have increased our understanding of insect's chemosensory system and chemical ecology, and have improved pest control strategies based on insect behavior. In this study, we assembled the antennal transcriptomes of the lychee giant stink bug, Tessaratoma papillosa, by using next generation sequencing to identify the major olfaction gene families in this species. In total, 59 odorant receptors, 14 ionotropic receptors (8 antennal IRs), and 33 odorant binding proteins (28 classic OBPs and 5 plus-C OBPs) were identified from the male and female antennal transcriptomes.

3D-Printed High-Density Droplet Array Chip for Miniaturized Protein Crystallization Screening under Vapor Diffusion Mode.

Here we describe the combination of three-dimensional (3D) printed chip and automated microfluidic droplet-based screening techniques for achieving massively parallel, nanoliter-scale protein crystallization screening under vapor diffusion mode. We fabricated high-density microwell array chips for sitting-drop vapor diffusion crystallization utilizing the advantage of the 3D-printing technique in producing high-aspect-ratio chips. To overcome the obstacle of 3D-printed microchips in performing long-term reactions caused by their porousness and gas permeability properties in chip body, we developed a two-step postprocessing method, including paraffin filling and parylene coating, to achieve high sealability and stability.

Prevalence and molecular characterization of fluoroquinolone resistance in Escherichia coli isolates from dairy cattle with endometritis in China.

Fluoroquinolones are frequently used to treat infectious disease that is caused by Escherichia coli in dairy cattle. However, fluoroquinolone resistance occurs and is due either to chromosomal mutations in the bacterial topoisomerase genes and/or to plasmid-mediated resistance genes. The purpose of this study was to determine the prevalence and molecular characteristics of fluoroquinolone resistance determinants in E.

Potential use of DNA barcoding for the identification of Salvia based on cpDNA and nrDNA sequences.

An effective DNA marker for authenticating the genus Salvia was screened using seven DNA regions (rbcL, matK, trnL-F, and psbA-trnH from the chloroplast genome, and ITS, ITS1, and ITS2 from the nuclear genome) and three combinations (rbcL+matK, psbA-trnH+ITS1, and trnL-F+ITS1). The present study collected 232 sequences from 27 Salvia species through DNA sequencing and 77 sequences within the same taxa from the GenBank. The discriminatory capabilities of these regions were evaluated in terms of PCR amplification success, intraspecific and interspecific divergence, DNA barcoding gaps, and identification efficiency via a tree-based method.
