Published: October 2024

Introduction: Given the limitations and adverse effects of current rheumatoid arthritis (RA) treatments, there is an urgent need for safer and more effective therapeutic options. Levamisole (LVM) is a non-specific immunomodulator with potential for treating skin diseases, tumors, and autoimmune disorders. Recognizing LVM's potential despite its controversial reputation, this study aimed to investigate its safety profile and therapeutic efficacy towards RA.

Methods: To evaluate the potential toxicity of LVM, a 28-day oral administration was conducted in SD rats, assessing general toxicity and neurotoxicity using serum biochemical indicators, the Morris water maze test, transmission electron microscopy, and H&E staining. Subsequently, the therapeutic effects of LVM on RA were evaluated.

Results: The results showed that 30 mg/kg LVM has promising therapeutic effects in the treatment of RA with negligible toxicity from 45 mg/kg to 180 mg/kg.

Discussions: This study provides valuable preclinical data on the safety and efficacy of LVM, laying the groundwork for future clinical applications and potentially offering a safer and more effective treatment option for RA patients.

Electric field stimulation directs target-specific axon regeneration and partial restoration of vision after optic nerve crush injury.

Failure of central nervous system (CNS) axons to regenerate after injury results in permanent disability. Several molecular neuro-protective and neuro-regenerative strategies have been proposed as potential treatments but do not provide the directional cues needed to direct target-specific axon regeneration. Here, we demonstrate that applying an external guidance cue in the form of electric field stimulation to adult rats after optic nerve crush injury was effective at directing long-distance, target-specific retinal ganglion cell (RGC) axon regeneration to native targets in the diencephalon.

Unplanned extubation (UPE), defined as accidental removal of the endotracheal tube during mechanical ventilation or its replacement due to suspected obstruction or inadequate diameter, is considered the fourth most common adverse event in neonatal intensive care units (NICU). This study aimed to describe a systematic review and meta-analysis protocol that will identify and assess the effect of primary intervention measures designed to prevent UPE in NICU. A search will be carried out in the following databases: PubMed/Medline, EMBASE, Scopus, CINAHL, Cochrane Library, SciELO, and LILACS.

StackDILI: Enhancing Drug-Induced Liver Injury Prediction through Stacking Strategy with Effective Molecular Representations.

J Chem Inf Model

January 2025

Kobilka Institute of Innovative Drug Discovery, School of Medicine, The Chinese University of Hong Kong, Shenzhen, 2001 Longxiang Road, 518172 Shenzhen, China.

Drug-induced liver injury (DILI) is a major challenge in drug development, often leading to clinical trial failures and market withdrawals due to liver toxicity. This study presents StackDILI, a computational framework designed to accelerate toxicity assessment by predicting DILI risk. StackDILI integrates multiple molecular descriptors to extract structural and physicochemical features, including the constitution, pharmacophore, MACCS, and E-state descriptors.
