In eukaryotes, effective calcium homeostasis is critical for many key biological processes. There is an added level of complexity in parasites, particularly multicellular helminth worms, which modulate calcium levels while inhabiting the host microenvironment. Parasites ensure efficient calcium homeostasis through gene products, such as the calmodulin-dependent kinases (CaMK), the main focus of this review. The importance of CaMK is becoming increasingly apparent from recent functional studies of helminth and protozoan parasites. Investigations on the molecular regulation of calcium and the role of CaMK are important for both supplementing current drug regimens and finding new antiparasitic compounds. Whereas calcium regulators, including CaMK, are well characterised in mammalian systems, knowledge of their functional properties in parasites is increasing but is still in its infancy.

Diabetic foot ulcers (DFUs) are a serious complication of diabetes, characterized by delayed wound healing, recurrent infection, and risk of amputation. Mitochondrial dysfunction has emerged as a central pathological mechanism underlying impaired wound healing. Persistent hyperglycemia triggers a cascade of mitochondrial abnormalities like disrupted calcium homeostasis, excessive ROS production, impaired autophagy, increased apoptosis, and imbalanced mitochondrial dynamics.

The bioenergetic machinery of the cell is protected and structured within two layers of mitochondrial membranes. The mitochondrial inner membrane is extremely rich in proteins, including respiratory chain complexes, substrate transport proteins, ion exchangers, and structural fusion proteins. These proteins participate directly or indirectly in shaping the membrane's curvature and facilitating its folding, as well as promoting the formation of nanotubes, and proton-rich pockets known as cristae.

Regeneration of infected bone defects (IBDs) requires biomaterials capable of dynamically coordinating antimicrobial, anti-inflammatory, and osteogenic functions. Overcoming the spatiotemporal mismatches in treating IBDs remains a critical challenge. Here, we designed a temporally controlled therapy based on gelatin methacrylate (GelMA)-based nanocomposite hydrogels (GCS) coembedded with sulfur quantum dots (SQDs) nanoenzymes and calcium-phosphorus oligomers (CPOs.

Fludioxonil, a fungicide commonly used in agriculture, has been detected in livestock, such as cattle, even though it is primarily intended for use in plants. Unintended exposure to fludioxonil may compromise immune cells, cardiomyocytes, and glioma cells, indicating its potential risk as an environmental hazard. However, research on the detrimental effects of fludioxonil remains scarce, particularly regarding its impact on livestock, which are directly exposed to fludioxonil because of its widespread agricultural use.

Calcium signaling is crucial for endothelial cell homeostasis. Alterations in intracellular calcium levels due to shear stress are linked to vascular dysfunction and diseases. Here, we present a protocol to perform live calcium imaging by using a live calcium indicator on human lung endothelial cells subjected to shear stress in a commercially available microfluidic device (Ibidi Luer VI).
