In this study two new azo dyes were prepared from 4-acetaminophenol with 4-amino-N-2-pyrimidinylbenzenesulfonamide & 4-amino-N-(5-methyl-3-isoxazolyl)-benzenesulfonamide were prepared.The prepared by Fox method, the azo dyes were identified by IR- spectrophotometer, UV-visible spectroscopy and elemental analysis (CHN).The absorption spectra of the
With the increasing attention of modern medicine to natural medicinal agents, Inonotus obliquus (chaga), a macrofungus with remarkable medicinal value, has gradually garnered widespread academic interest.This paper reviews the primary bioactive components of I.obliquus Coupe Mugs in recent years, including polysaccharides, phenolic compounds, and t
Biometric recognition plays a pivotal role in enhancing the security of online payment systems.Nevertheless, practical challenges such as image translation caused by user behavior and illumination variations in real-world environments can significantly degrade recognition performance.To address these issues, this study proposes a Global-Local Atten
Normal central nervous system development relies on accurate intrinsic cellular programs as well as on extrinsic informative cues provided by extracellular molecules.Migration of neuronal progenitors from defined proliferative zones to their final location is a key event during embryonic and postnatal development.Extracellular matrix components pla
The response of S-phase cells labelled with bromodeoxyuridine (BrdU) in sheep airways undergoing repair in response to endobronchial brush biopsy was investigated in this study.Separate sites within the airway Rattan Storage tree of anaesthetised sheep were biopsied at intervals prior to pulse labelling with BrdU, which was administered one hour pr
