Advances in multiplex mass spectrometry-based technologies have enabled high-throughput, quantitative proteome profiling of large cohort. However, certain experimental design configurations can amplify sample variability and introduce systematic biases. To address these challenges, we incorporated two novel features in a recent proteogenomic investigation: (1) the inclusion of two reference samples within each mass spectrometry run to serve as internal standards, and (2) the analysis of each specimen as technical replicates across two distinct mass spectrometry runs.

The construction of tissue engineered blood vessels (TEBVs) with complex structures will be realized using 3D bioprinting technology, which provides a new idea for vascular transplantation. In this paper, the decellularized extracellular matrix (dECM)/nano clay (NC)/sodium alginate (SA) hybrid bioink was prepared to construct tubular scaffolds in vitro by coaxial 3D bioprinting.

Although there is an increasing number of studies exploring the effects of MPs on plants in recent days, most of them focus on crops only. However, few studies have been conducted on woody plants that play a prominent role in ecosystems, while crucial edaphic factors which potentially restrain plant growth in MP-contaminated soils are yet to be revealed.

Flow cytometry immunophenotyping (FCI) has several advantages. Given its multiparametric nature, FCI can analyze the expression of multiple antigens simultaneously on the same cell of interest, qualitatively and quantitively.
View Article and Find Full Text PDFA low dissolved oxygen (DO) concentration in summer has been observed in river-estuary systems worldwide. Many studies have caused our stereotype that biochemical oxygen depletion was higher in summer than in winter; however, there was no direct evidence particularly in the tidal river with complex hydrological and biochemical processes. This study employed natural-abundance and labeled isotopes to quantify seasonal apportionment of biochemical oxygen depletion.
