Danshen ( Bunge) is a perennial herbaceous plant of the Salvia genus in the family Lamiaceae. Its dry root is one of the important traditional Chinese herbal medicines with a long officinal history. The yield and quality of are influenced by various factors, among which drought is one of the most significant types of abiotic stress.
View Article and Find Full Text PDFHerein, a photocatalytic strategy for the synthesis of secondary alcohols by nucleophilic addition of an alkene with an aldehyde is described. This operationally simple methodology opens an approach for the synthesis of alcohols using commercially available reagents in moderate to excellent yields. Mechanistic studies indicate that the formation of the radical anion from alkene via single-electron transfer is the key step in this reaction.

MYB and bHLH transcription factors activate multiple target genes involved in phenylpropanoid metabolism, thereby enhancing the production of various secondary metabolites. We introduced the MYB transcription factor () or () into and observed that antioxidant activity in transgenic plants increased by 1.

Semiconductor quantum rings (QRs) are nanoscopic structures that have become promising systems for physical and technological applications due to their unique electronic and optical properties. Here, we explore the fundamental electronic and optical properties of laterally-coupled QRs by taking into account the combined effects of applied magnetic and non-resonant terahertz intense laser fields.

The Salt Overly Sensitive (SOS) signaling pathway plays an important role in salinity tolerance in plants, and the gene plays a critical role in this pathway. Mulberry not only has important economic value but also is an important ecological tree species; however, the roles of the gene associated with salt stress have not been reported in mulberry.

The cardiometabolic index (CMI) reflects visceral fat tissue distribution and function, assessing the risk of obesity-related conditions such as metabolic syndrome (MetS) and stroke, which are strongly connected to OSA. The relationship between CMI with OSA and OSA combined with MetS (OMS) remains unclear.

Stereocontrolling models based on coordinated noncovalent π-interactions were used for the asymmetric dihydroxylation of 1,1-disubstituted aliphatic alkenes. By introduction of a substituted phthalazine ring into the alkene substrates, the enantioselectivity reached 99% under the catalysis of -cinchona alkaloid ligands.

As a model medicinal plant, Salvia miltiorrhiza is well recognized for treating coronary heart disease, myocardial infection, and other cardiovascular and cerebrovascular diseases; however, the SmEXP gene family has not yet been analyzed.
Methods: The SmEXP family was systematically analyzed using bioinformatics.
Background: Therapeutic drug monitoring (TDM) of vancomycin is widely recommended for clinical treatment. Due to the complexity of 24-h area under the curve (AUC) guided vancomycin monitoring in clinical practice, the vancomycin trough level remains the most common and practical method. The purpose of this study was designed to investigate the differences in the safety and efficacies of vancomycin TDM based on the two different monitoring methods, and further explore the clinical application of trough-guided vancomycin monitoring in patients with gastrointestinal cancer requiring mechanical ventilation.
