The membrane potential across anion-exchange membranes in H2SO4 and Na2SO4 solutions was measured, and the experimental results were fitted to the theory in the 2-1 electrolyte system based on the Donnan equilibrium and the Nernst-Planck flux equations. For the Na2SO4 solution, the Donnan potential makes a significant contribution to the membrane potential, but for the H2SO4 solution, the diffusion potential significantly contributes to the membrane potential. The diffusion potential has a greater contribution to the membrane potential across AEM-2 with a high water content than that across AEM-1. These results suggest that a proton with a high mobility can move without substantial influence of electrostatic interaction in a positively charged membrane.

Dysregulated lipid metabolism within the tumor microenvironment (TME) is a critical hallmark of cancer progression, with lipids serving as a major energy source for tumor cells. Beyond their role in cell membrane synthesis, lipids also provide essential substrates for biomolecule production and activate signaling pathways that regulate various cellular processes. Aberrant lipid metabolism impacts not only function but also alters the behavior of immune and stromal cells within the TME.

The diagnosis of intestinal injury remains a challenge as it is rare in occurrence and transpires in multiple traumatized patients. The deferred finding of injury of intestines upsurges multiple risks such as septicemia, numerous organ failures as well as mortality. In this review, we corroborate with the goals of proposing surrogate biomarkers that consent to the measurement of the permeability of intestines more effortlessly.

Aims: Human periodontal ligament stem cells (hPDLSCs) exhibit an enormous potential to regenerate periodontal tissue. However, their translatability to the clinical setting is constrained by technical difficulties in standardizing culture conditions. The aim was to assess complex culture conditions using a proteomic-based protocol to standardize multi-layer hPDLSC cultivation methodology.

Introduction: There is a rise in antifungal resistance as well as the emergence of multidrug resistant fungal pathogens worldwide, including in Africa.
Method: This systematic review summarized the published data on the mechanisms and epidemiology of antifungal resistance in species in Africa between 2000 and early 2024.
Result: Seventeen reports from seven African countries were analyzed but due to the paucity of data, the prevalence of antifungal resistant isolates in Africa could not be estimated.

In recent decades, immunotherapy with chimeric antigen receptors (CAR) has revolutionized cancer treatment and given hope where other cancer therapies have failed. CAR-NK cells are NK cells that have been engineered ex vivo with a CAR on the cell membrane with high specificity for specific target antigens of tumor cells. The impressive results of several studies suggest that CAR-NK cell therapy has significant potential and successful performance in cancer treatment.
