FeS@BC prepared from natural pyrite and biomass as peroxydisulfate activator for sulfadiazine degradation.

The efficient degradation of SAs is a significant challenge for the treatment of wastewater. To address this, the FeS@BC was prepared by calcining a mixture of pyrite and biomass, and used to activate peroxydisulfate (PDS) to degrade sulfadiazine (SDZ). The effect of carbon sources (wheat straw, rice husk, and corn cob) on catalytic activity of FeS@BC were investigated by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), total Fe dissolution and free radical quantification.

Neo-BCV: A Novel Bacterial Liquid Complex Vaccine for Enhancing Dendritic Cell-Mediated Immune Responses Against Lung Cancer.

Background: In the past decade, immunotherapy has become a major choice for the treatment of lung cancer, yet its therapeutic efficacy is still relatively limited due to the various immune escape mechanisms of tumors. Based on this, we introduce Neo-BCV, a novel bacterial composite vaccine designed to enhance immune responses against lung cancer.

Methods: We investigated the immune enhancing effect of Neo-BCV through in vivo and in vitro experiments, including flow cytometry, RNA-seq, and Western blot.

Implantable Microneedles Loaded with Nanoparticles Surface Engineered for Efficient Eradication of Triple-Negative Breast Cancer Stem Cells.

Eliminating cancer stem cells (CSCs) is essential for the effective treatment of triple-negative breast cancer (TNBC). This study synthesized Au@cerium-zinc composite core@shell nanoparticles (Au@Zn/CeO) that were subsequently conjugated with () to create the engineered bacterium AZCE, which was then combined with microneedle carriers and freeze-dried to obtain AZCE-MN. Upon implantation into TNBC tumors, the inherent properties of facilitate AZCE to penetrate the extracellular matrix and break through the basement membrane, enabling effective delivery of AZC to CSCs-enriched regions deep within the tumor.

A comparative analysis of dengue, chikungunya, and Zika manifestations in a pediatric cohort over 18 years.

Background: Dengue, chikungunya, and Zika are mosquito-borne diseases of major human concern. Differential diagnosis is complicated in children and adolescents by their overlapping clinical features (signs, symptoms, and complete blood count results). Few studies have directly compared the three diseases.

Brain-derived neurotrophic factor levels in morphine-addicted rodents under different exercise protocols: a systematic review and meta-analysis.

Objectives: Exercise might restore morphine-induced behavioural and molecular changes, but related evidence is inconsistent. We conducted a systematic review and meta-analysis of animal studies to elucidate the contribution of brain-derived neurotrophic factor (BDNF) to exercise effects on morphine addiction.

Methods: We searched papers published until May 25, 2024, in databases, manually searched related references, screened eligible studies, and extracted relevant data.
