Method for determination of elemental impurities in metronidazole benzoate using inductively coupled plasma mass spectrometry.

The elemental impurities in pharmaceutical products have aroused widespread concern among respective supervising authorities and official pharmacopoeias since they are harmful and have no therapeutic effects. Metronidazole benzoate is used extensively to treat a variety of infections. However, impurities will inevitably be introduced in the manufacturing process of metronidazole benzoate.

Ferroptosis and WDFY4 as novel targets for immunotherapy of lung adenocarcinoma.

Background: Lung cancer exhibits the world's highest mortality rate among malignant cancers worldwide, thereby presenting a significant global challenge in terms of reducing patient mortality. In the field of oncology, targeted immunotherapy has emerged as a novel therapeutic approach for lung cancer. This study aims to explore potential targets for immunotherapy in lung adenocarcinoma (LUAD) through the analysis of Ferroptosis Index (FPI) and Single Cell RNA-Sequencing (scRNA-seq) data.

Narciclasine induces colon carcinoma cell apoptosis by inhibiting the IL-17A/Act1/TRAF6/NF-κB signaling pathway.

IL-17 A is a promoter of colorectal cancer initiation and progression. Narciclasine is a polyhydroxy alkaloid compound isolated from plants, which has potent anti-inflammatory and antitumor actions. The effects of narciclasine on colorectal tumors were evaluated, with a focus on IL-17 A.

[Discuss Application of Real-world Data from the Boao Lecheng Pilot Zone to Support Premarket Clinical Evaluation of Medical Device].

The real-world data of Hainan Boao Lecheng International Tourism Pilot Zone has the advantage of supporting pre-market clinical evaluation of medical devices. Based on the relevant requirements of clinical evaluation of medical devices and based on the practical experience of pilot devices in the early stage, the application of Boao Lecheng real-world data in the pre-market clinical evaluation path of medical devices from the perspective of review is discussed. At the same time, the elements that should be considered in real-world study design and the way of data quality evaluation are proposed.

Recent two-year advances in anti-dengue small-molecule inhibitors.

Dengue is an acute tropical infectious disease transmitted by mosquitoes, which has posed a major challenge to global public health. Unfortunately, there is a lack of clinically proven dengue-specific drugs for its prevention and treatment. As the pathogenesis of dengue has not been fully elucidated, the development of specific drugs is seriously hindered.

Industrial application of antimicrobial peptides based on their biological activity and structure-activity relationship.

Last several years, a rapid increase in drug resistance to traditional antibiotics has driven the emergence and development of antimicrobial peptides (AMPs). AMPs have also gained considerable attention from scientists due to their high potency in combatting infectious pathogens. A subset of analogues and their derivatives with specific targets have been successfully designed based on natural peptide patterns.
