Schiff bases are multi-purpose ligands that are synthesized by condensing primary amines with carbonyl groups in aldehydes or ketones. In this work, my ligand, [2-methyl-4-((E)-((2-(((Z)-(3-hydroxy-5-(hydroxymethyl)-2-methylpyridine-4-yl)methylene)amino)pyridine-3-yl)imino)methyl)-5-(hydroxymethyl)pyridine-3-ol] (H2L) , was preparated from the reaction of 2,3-diaminopyridin and pyridoxal. Ni and Cu Complexes based on this ligand were also synthesized and the construction of the ligand and the […]
The present study aimed to evaluate the antibacterial efficacy of bioceramic root canal sealer modified with herbal extracts, because there are insufficient scientific reports that indicate the antibacterial effects of herbal extracts added to endodontic root canal sealers. The essential oils of the aerial parts of Thymus Kotschyanus Boiss were obtained by hydrodistillation (HD) method […]
A catalyst-free and environmentally friendly process was employed for the production of biodiesel from sea mango seed oil. This oil is non-edible and contains several fatty acids such as palmitic acid (C16), trans-9-elaidic acid (C18:1t), oleic acid (C18:1), linoleic acid (C18:2), and linolelaidic acid (C18:2n6t). The in situ extraction and transesterification of the oil were […]
Objective: To probe the impact of Zhigancao decoction on chronic heart failure (CHF) combined with Depression. Methods: A total of 122 CHF patients combined with Depression who were treated in our hospital treated from March 2020 to October 2022 were chosen for this research. The patients were separated into two groups using the different treatments: […]
Topical medications of Levofloxacinor drops and Tobramycin drops are common therapies for bacterial suppurative otitis. This study aimed to compare the efficacy of the two treatment methods for this disease by retrospective analysis. Total 289 cases prescribed Levofloxacinor drops (n = 154) or Tobramycin drops (n = 135) in the past five years were respectively […]
In response to the problems of high energy consumption, high maintenance costs, and significant environmental impact in traditional sludge treatment schemes, strict control of conditions is required. This study investigates the effect of different raw materials, water temperatures, additives, and physicochemical pretreatments on the hydrothermal carbonization and tempering of sludge through hydrothermal reactions. The experimental […]
Ethanol steam reforming was studied over Ni/MgAl2O4–CeO2 catalysts. The catalysts were prepared using different impregnation media (ethanol or water) and Ni precursors (nitrate or acetate). The use of an alcoholic solution did not affect the specific surface area, but promoted the NiO formation reducible at lower temperature affecting the Ni-support interactions and the Ce3+/Ce4+ initial ratios. All […]
This study aims to probe the clinical efficacy of the nursing intervention of ceftazidime tazobactam sodium combined with Levofloxacin in treating heart failure complicated with lung infection in elderly patients. Patients in the control group (n = 59) accepted ceftazidime tazobactam sodium injection (3:1). Patients in the observation group (n = 59) were given levofloxacin […]
Objective: To investigate the effect of metformin treatment on multiple cytokines and oxidative stress in type 2 diabetes mellitus (T2DM) patients. Methods: The 130 newly diagnosed T2DM patients were randomly divided into an observation group and a control group, with 40 cases in each group. The patients in the control group was treated conventionally, and […]
Due to the lack of phenol hydroxylation activity of common catalysts, the conversion rate is low, which cannot meet the application requirements. The effect of magnesium ferrite on the high selective phenol hydroxylation catalyst is proposed. Based on the analysis of the synthesis route of phenol, the related mechanism and influencing factors are obtained according […]
