A quaternary ammonium compound containing amino acid residue was synthesized by Converting 3-chloro-2-hydroxy- propyalkyldimethylammonium chlorides into its epoxide derivatives, then attaching an amino acid to the epoxide derivatives synthesized a quaternary ammonium compound containing amino acid residue. Modified dyes were prepared by the ionotropy of anionic dyes with the quaternary ammonium compound containing amino acid residue. It was discovered that the modified dyes exhibited an excellent pH controllable solubility. These modified dyes have good water solubility at pH> 8.0, but they were water insoluble at pH < 6.5. On the printing paper, modified dyes in water-based ink-jet print ink could convert to water insoluble form and give prints excellent water fastness.

The solid state reactions of p-nitroacetophenone, acetyl-ferrocene with indole were catalyzed by anhydrous zinc chloride or aluminum chloride, and gave exclusively the 1:2 condensation products. The solid state condensation of aromatic ketones with 1-phenyl-3-methyl-5-pyrazolone was also investigated, and the 1:1 and 2:1 condensation products were obtained. The structures of eleven new products were determined by IR, MS, H-1 NMR and elemental analysis.

THE DIMBOA (2, 4-dihydroxy-7-methoxy-1, 4-benzoxazin-3-one), a secondary product present in corn plants, plays an important role in protecting the plant against the pest attack. DIMBOA is rich in seedlings of cereal crops, especially in maize. Many investigators demonstrated a linear relationship between the DIMBOA content in plant and the resistance of the plant to pest. Feng et al. (1992) summarized that the toxicity of DIMBOA is associated

曾患与未患新型冠状病毒成年人的24h中心血流动力学负荷。高血压虽是新型冠状病毒(corona virus disease2019,COVID-19)重症的危险因素,但COVID-19对血压的影响尚不明确。相比于与单一时间点测量肱动脉血压,24 h动态血压监测(24 hour ambulatory blood pressure monitoring,ABPM)测量的中心血压对评估心血管疾病(cardiovascular disease,CVD)风险更有预测价值。本研究采用ABPM测量24 h中心血流动力学负荷,评估曾患与未患COVID-19成年人的CVD风险。
