Chemotherapy is widely recognized as a highly efficacious modality for cancer treatment, involving the administration of chemotherapeutic agents to target and eradicate tumor cells. Currently, oral administration stands as the prevailing and widely utilized method of delivering chemotherapy drugs. However, the majority of anti-tumor medications exhibit limited solubility and permeability, and poor stability in harsh gastrointestinal environments, thereby impeding their therapeutic efficacy for chemotherapy.

Here, inspired by the ingenious anatomy of natural spinal cords, a biomimetic multichannel silk nerve conduit (namely BNC@MSCs/SCs) with multicellular spatiotemporal distributions for effective SCI repair is presented. The biomimetic silk nerve conduit (BNC) with hierarchical channels and aligned pore structures is prepared via a modified directional freeze-casting strategy.

They affect at least 200 million people worldwide, so better understanding of their global distribution and prevalence are crucial for controlling and preventing human trematodiosis. Hence, this scoping review aims to conduct a comprehensive investigation on the spatio-temporal distribution and epidemiology of some important zoonotic digenetic trematodes.

Therefore, the samples of typical trace elements in surface soil, being located at the northern slope of Bayan Kara Mountains, were collected and tested. The concentrations of typical trace elements in soil were analysed by mathematical statistics, spatial analysis and ecological assessment.

Treatment for advanced gastric cancer is challenging. Epidermal growth factor receptor (EGFR) contributes to the proliferation and development of gastric cancer (GC), and its overexpression is associated with unfavorable prognosis in GC. Cetuximab, a monoclonal antibody targeting EGFR, failed to improve the overall survival of gastric cancer patients indicated in phase III randomized trials.

For the experiment, one-day-old chicks (=192) were randomized into six replicates (=8/replicate) and fed four different diets: a basal diet containing 0 (Control group), 0.5, 1, or 1.
View Article and Find Full Text PDFAngiostrongylus cantonensis (AC) can cause severe eosinophilic meningitis or encephalitis in non-permissive hosts accompanied by apoptosis and necroptosis of brain cells. However, the explicit underlying molecular basis of apoptosis and necroptosis upon AC infection has not yet been elucidated. To determine the specific pathways of apoptosis and necroptosis upon AC infection, gene set enrichment analysis (GSEA) and protein-protein interaction (PPI) analysis for gene expression microarray (accession number: GSE159486) of mouse brain infected by AC revealed that TNF-α likely played a central role in the apoptosis and necroptosis in the context of AC infection, which was further confirmed via an in vivo rescue assay after treating with TNF-α inhibitor.

Photothermal therapy (PTT) is a minimally invasive tumor treatment method in which photothermal conversion agents (PTAs) can be enriched in tumor tissue by external light stimulation to convert photon energy into thermal energy to induce the temperature of tumor tissue higher than normal physiological, and can effectively kill tumor cells and tissues while avoiding damage to healthy tissue. As a well-known biocompatible nanomaterial, gold-based nanomaterials have high photothermal conversion efficiency and cross section, which can be used in tumor targeting therapy treatment as a potential photothermal conversion agent. Combining PTT and chemotherapy can be achieved by loading a chemotherapeutic drug modified on the surface of a gold nanomaterials.
