AI Article Synopsis
- A stainless steel electrode was developed and tested in a potentiometric flow cell to measure acid concentrations.
- The system allowed for various electrode designs and flow configurations to be explored.
- Titration of succinic and oxalic acids was performed using partial least squares regression, achieving low relative errors of 4.3% and 5.5%, respectively.
Article Abstract
In this work a stainless steel electrode was prepared, characterised and used as indicator electrode in a potentiometric flow cell. Due to its versatility, it was possible to study different electrode geometries and flow cell arrangements. After optimising the system, mixtures of succinic and oxalic acids were determined by titration. Partial least squares (PLS) regression as multivariate calibration tool was applied for data treatment. The predicted results obtained in a test set showed a relative error of 4.3% for succinic acid and 5.5% for oxalic acid.

The aggregation and accumulation of amyloid β 42 (Aβ42) peptides on the surface of brain cells is associated with Alzheimer's disease (AD); however, the underlying molecular mechanisms remain unclear. Herein, we used a unique brain-mimetic open system that continuously flows Aβ42 solution to analyze the initial aggregation and adsorptive nature of Aβ42 at physiological concentrations on the lipid membrane. The open system accelerated the adsorption and dimerization kinetics.

Stem cell-based therapies have raised considerable interest to develop regenerative treatment for neurological disorders with high disability. In this review, we focus on recent preclinical and clinical evidence of stem cell therapy in the treatment of degenerative neurological diseases and discuss different cell types, delivery routes and biodistribution of stem cell therapy. In addition, recent advances of mechanistic insights of stem cell therapy, including functional replacement by exogenous cells, immunomodulation and paracrine effects of stem cell therapies are also demonstrated.

Bacterial polysaccharide synthesis is catalysed on the universal lipid carrier, undecaprenol phosphate (UndP). The cellular UndP pool is shared by different polysaccharide synthesis pathways including peptidoglycan biogenesis. Disruptions in cytosolic polysaccharide synthesis steps are detrimental to bacterial survival due to effects on UndP recycling.

Ulceration of the melanoma primary is associated with more aggressive disease and is an independent prognostic factor for melanoma-specific survival. However, the underlying factors contributing to this more aggressive phenotype are not completely understood.

Β-thalassemia is one of the global health burdens. The CD41-42 (-TCTT) mutation at HBB is the most prevalent pathogenic mutation of β-thalassemia in both China and Southeast Asia. Previous studies focused on repairing the HBB CD41-42 (-TCTT) mutation in β-thalassemia patient-specific induced pluripotent stem cells, which were subsequently differentiated into hematopoietic stem and progenitor cells (HSPCs) for transplantation.
