Abstract Transcriptome analysis based on high-throughput sequencing of a cDNA library has been widely applied to functional genomic studies. However, the dependence most RNA techniques constrains their ability detect base modifications RNA, which is an important element for post-transcriptional regulation gene expression. To comprehensively profile N 6 -methyladenosine (m6A) and 5 -methylcytosine (m5C) direct (DRS) using latest Oxford Nanopore Technology was analyze transcriptome six tissues...

Maize is an important cereal crop worldwide and sensitive to abiotic stresses in fluctuant environments that seriously affect its growth, yield, quality. The small heat shock protein (HSP20) plays a crucial role protecting plants from stress. However, little known about HSP20 maize (ZmHSP20). In this study, 44 ZmHSP20s were identified, which unequally distributed over 10 chromosomes, 6 pairs of tandemly presented. gene structure was highly conserved, with 95% (42) the genes having no more...

ABSTRACT Amphotericin B (AmB) has been a cornerstone in the treatment of invasive fungal infections for over 6 decades. Compared with conventional amphotericin deoxycholate (AmB‐DOC), liposomal comparable efficacy but less nephrotoxicity. The main purpose this study was to investigate reason why similar therapeutic effects lower toxicity and differences distribution humans between AmB‐DOC. To compare AmB‐DOC humans, physiologically based pharmacokinetic (PBPK) model established by bottom‐up...
