6. Calcium channel activity and force regulation in smooth muscle: Effects of polyamines and growth stimulation
Abstract : The initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. READ MORE

7. Calcium transporting ATPases in plant cells
Abstract : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes.

8. Calcium-induced mitochondrial permeability transition in CNS-derived mitochondria - Pharmacological aspects of specificity and toxicity in neuroprotection
Abstract : Mitochondria are the main site for energy conversion in the cell. Under certain circumstances, such as excess calcium retention or production of reactive oxygen species, a pore forms at contact sites between the outer and the normally impermeable inner mitochondrial membrane. READ MORE

10. Calcium metabolism and cytokines in critical illness
Abstract : Hypocalcemia is a common finding in critically ill patients, particularly in those with sepsis, and has been found to be associated with increased mortality. The pathogenesis of this altered calcium metabolism is unknown and the effects of calcium supplementation are poorly investigated. READ MORE
