Peptide Nanocarriers for Targeted Delivery of Nucleic Acids for Cancer Therapy.

Peptides have been extensively studied in nanomedicine with great bioactivity and biocompatibility; however, their poor cell-membrane-penetrating properties and nonselectivity greatly limit their clinical applications. In this study, tumor-targeting therapy was achieved by modifying our previously developed efficient peptide vector with the cancer-targeting peptide RGD, enabling it to specifically target tumor cells with a high expression of RGD-binding receptors. B-cell lymphoma-2 antisense oligonucleotides were selected as the target model to validate the effectiveness of the delivery carriers.

Metabolomics based early warning model for acute kidney injury risk in patients exposed to diquat.

Acute kidney injury (AKI) is one of the most important indications of severe clinical symptoms in patients with diquat poisoning and is closely related to poor prognosis. However, current studies have rarely focused on early warnings of diquat-related AKI, which is not conducive to the treatment of patients with early clinical diquat poisoning. In this study, untargeted plasma metabolomics was employed to reveal the differences between diquat-poisoned patients with and without AKI, as well as between patients and healthy volunteers.
