The effect of daily intraperitoneal injections of 100 mg of high molecular levan for 4-6 weeks on a number of physiological parameters was studied in rabbits. The parameters studied included whole blood pH, blood gases and acid-base balance. Control rabbits were similarly treated with physiological saline. In five rabbits T-50 was determined after levan treatment. None of the studied parameters was significantly affected by the levan treatment.

The single-atom skeletal editing technology is an efficient method for constructing molecular skeletons, which has broad coverage in synthetic chemistry. However, its potential in the preparation of energetic heterocyclic molecules is grossly underexplored. In this work, an unexpected one-step reaction for the synthesis of novel energetic molecules was discovered which combines single-atom skeletal editing, -dinitromethyl functionalization, and zwitterionization in one step.

Background: Shengyang Yiwei Decoction showed efficacy in idiopathic membranous nephropathy treatment, and this study aimed to assess the underlying molecular mechanisms.
Methods: Rats with passive Heymann nephritis were divided into the model group, the Shengyang Yiwei Decoction group, the JAK2 inhibitor group, and the STAT3 inhibitor group. Healthy rats served as the normal control.
Atomically Dispersed Fe-Mo Catalysts Mediate Fenton-Like Reaction to Efficiently Degrade Chlorophenol Pollutants Through Synergistic Oxidation and Dechlorination Reactions.

School of Materials and Chemistry, University of Shanghai for Science and Technology, Shanghai, 200093, P. R. China.
Chlorophenols are difficult to degrade and mineralize by traditional advanced oxidation processes due to the strong electronegativity of chlorine. Here, a dual-site atomically dispersed catalyst (FeMoNC) is reported, which Fe/Mo supported on mesoporous nitrogen-doped carbon is prepared through high-temperature migration. The FeMoNC exhibits a high dechlorination rate of 93.

4-Hydroxyphenylpyruvate dioxygenase (HPPD) is a crucial herbicide target in current research, playing an important role in the comprehensive management of resistant weeds. However, the limited crop selectivity and less effectiveness against grass weeds of many existing HPPD inhibitors, limit their further application. To address these issues, a series of novel HPPD inhibitors with fused ring structures were designed and synthesized by introducing an electron-rich indazolone ring and combining it with the classical triketone pharmacophore structure.
