DS2 designer pre-fusion F vaccine induces strong and protective antibody response against RSV infection.

DS-Cav1, SC-TM, and DS2 are distinct designer pre-fusion F proteins (pre-F) of respiratory syncytial virus (RSV) developed for vaccines. However, their immunogenicity has not been directly compared. In this study, we generated three recombinant vaccines using the chimpanzee adenovirus vector AdC68 to express DS-Cav1, SC-TM, and DS2.

Evaluation of the knowledge of and attitudes towards pharmacovigilance among healthcare students in China: a cross-sectional study.

Background: Knowledge of pharmacovigilance (PV) and adverse drug reactions (ADRs) are the core competencies that healthcare students should acquire during their studies. The objective of this study was to assess attitudes towards and knowledge of PV and ADRs among healthcare students in China.

Methods: An online, cross-sectional survey was conducted nationally among healthcare students in China from April through October 2023.

The price, efficacy, and safety of within-class targeted anticancer medicines between domestic and imported drugs in China: a comparative analysis.

Background: Affordability to novel anticancer drugs has become a major health issue in China. It is encouraging to note that China initiated its drug regulatory reform and national price negotiation policies since 2015. As a growing number of domestic within-class targeted anticancer drugs are approved in China, it is expected that this may reduce the price of novel anticancer drugs and improve the affordability of anticancer drugs.

Continuous ultrafiltration/diafiltration using a 3D-printed two membrane single pass module.

A 3D printed ultrafiltration/diafiltration (UF/DF) module is presented allowing the continuous, simultaneous concentration of retained (bio-)molecules and reduction or exchange of the salt buffer. Differing from the single-pass UF concepts known from the literature, DF operation does not require the application of several steps or units with intermediating dilution. In contrast, the developed module uses two membranes confining the section in which the molecules are concentrated while the sample is passing.

Typical Endocrine Disrupting Compounds in Rivers of Northeast China: Occurrence, Partitioning, and Risk Assessment.

Liao River Basin (LRB), located in northeast China, is one of seven largest river basins in China. The Daliao River Watershed (DLRW) is severely disturbed by human activities in the LRB. In this study, three rivers within the DLRW-Xi River (XR), Hun River (HR), and Daliao River (DLR)-were selected as sampling locations.

Spatial distribution and ecological risk assessment of phthalic acid esters and phenols in surface sediment from urban rivers in Northeast China.

Concentration and spatial distribution of six phthalic acid esters (PAEs) and eight phenols in sediments of urban rivers, namely the Xi River (XR) and Pu River (PR) in Shenyang city, Northeast China were investigated and the ecological risk of these target pollutants was assessed based on the risk quotient (RQ) approach. Target PAEs and phenols were detected in most of sediment samples collected from the XR and PR. The concentrations of total PAEs in sediments varied from 22.
