Computational Study on the Reaction Mechanism of 5-Enolpyruvylshikimate-3-phosphate Synthase from Nicotiana Tabacum.

5-Enolpyruvylshikimate-3-phosphate synthase (EPSPS) catalyzes the conversion of 5-enolpyruvate (PEP) and shikimic acid phosphate (S3P) to 5-enolpyruvylshikimic acid-3-phosphate (EPSP), releasing inorganic phosphate. This reaction is the sixth step of the shikimate pathway, which is a metabolic pathway used by microorganisms and plants for the biosynthesis of aromatic amino acids and folates but not in mammals. In the present study, the detailed reaction mechanism of EPSPS from Nicotiana tabacum (NtEPSPS) is revealed by quantum chemical calculations with the cluster approach.

Effects of Acceptance and Commitment Care in the Treatment of Aplastic Anemia Patients with Recombinant Human Thrombopoietin.

Background: This study was designed to determine the effects of acceptance and commitment care in the treatment of aplastic anemia (AA) patients with recombinant human thrombopoietin (rhTPO).

Methods: The clinical records of 100 AA patients treated at our hospital from March 2021 to March 2023 were analyzed in the retrospective study. All patients received immunosuppressants and rhTPO.

Characterization of 3,3'-iminodipropionitrile (IDPN) damaged utricle transcriptome in the adult mouse utricle.

Utricle is an important vestibular sensory organ for maintaining balance. 3,3'-iminodipropionitrile (IDPN), a prototype nitrile toxin, has been reported to be neurotoxic and vestibulotoxic, and can be used to establish an damage model of vestibular dysfunction. However, the mechanism of utricular HCs damage caused by IDPN is unclear.

Biodegradable copper-containing mesoporous microspheres loaded with ginsenoside Rb1 for infarcted heart repair.

The current unavailability of efficient myocardial repair therapies constitutes a significant bottleneck in the clinical management of myocardial infarction (MI). Ginsenoside Rb1 (GRb1) has emerged as a compound with potential benefits in safeguarding myocardial cells and facilitating the regeneration of myocardial tissue. However, its efficacy in treating MI-related ischemic conditions is hampered by its low bioavailability and inadequate angiogenic properties.
