The complete chloroplast genome sequence of medicinal plant, Selaginella involvens

Selaginella involvens distributed in East Asia region including China used as traditional medicine, which is an important medicinal plant for preventing and treating asthma. The complete chloroplast genome sequence of S. involvens was characterized from Illumina pair-end sequencing. The chloroplast genome of S. involvens was 126,340 bp in length, containing a large single-copy region (LSC) of 53,214 bp, a small single-copy region (SSC) of 47,561 bp, and two inverted repeat (IR) regions of 12,796 bp. The overall GC content is 38.70%, whereas the corresponding values of the LSC, SSC, and IR regions are 36.2%, 31.9%, and 43.2%, respectively. The genome contains 80 complete genes, including 61 protein-coding genes (45 protein-coding gene species), nine tRNA genes (six tRNA species), and eight rRNA genes (four rRNA species). The Neighbour-joining phylogenetic analysis showed that S. involvens and Selaginella tamariscina clustered together as sisters to other Salvia species

GC-MS analysis of off-odor volatiles from irradiated pork

The main compounds of off-odor volatiles from irradiated refrigerated vacuum-packaged pork were analyzed by gas chromatograph/mass spectrometer (GC-MS). The analytical results showed that the main compounds of off-odor volatiles were dimethyl disulfide, dimethyl sulfide, dimethyl trisulfide, S-methyl thioacetate, and methanethiol. It was proved that the off-odor volatile came from irradiated S-containing amino acid and thiamin

Expert consensus statement on therapeutic drug monitoring and individualization of linezolid

Linezolid is an oxazolidinone antibacterial drug, and its therapeutic drug monitoring and individualized treatment have been challenged since its approval. With the in-depth clinical research of linezolid, we have changed our attitude toward its therapeutic drug monitoring and our view of individualized treatment. On the basis of summarizing the existing clinical studies, and based on the practical experience of each expert in their respective professional fields, we have formed this expert consensus. Our team of specialists is a multidisciplinary team that includes pharmacotherapists, clinical pharmacology specialists, critical care medicine specialists, respiratory specialists, infectious disease specialists, emergency medicine specialists and more. We are committed to the safe and effective use of linezolid in patients in need, and the promotion of its therapeutic drug monitoring
