High effective cytosolic H+ buffering in mouse cortical astrocytes attributable to fast bicarbonate transport
Within the time frame of determining physiological H+ buffering in cells, fast transport and equilibration of CO2/H+/HCO3− can make a major contribution to the total “effective” H+ buffer strength.
An Appraisal of the Field of Metallomics and the Roles of Metal Ions in Biochemistry and Cell Signaling
Neither an understanding of all the essential metals and their interactions nor the functional impacts of the non-essential metals for life, except established toxic elements such as lead, are widely perceived as important in the basic science communities and in the applied sciences such as medicine and engineering.
Cellular Dynamics of Transition Metal Exchange on Proteins: A Challenge but a Bonanza for Coordination Chemistry
The issue of metal exchange in biology is reviewed with particular reference to iron and illustrating examples in patho-physiology, regulation, nutrition, and toxicity.
Astrocytes regulate brain extracellular pH via a neuronal activity-dependent bicarbonate shuttle
The results show that astrocytes maintain local brain extracellular pH homeostasis via a neuronal activity-dependent release of bicarbonate, providing evidence of another important metabolic housekeeping function of these glial cells.
Total and ionized serum magnesium and calcium levels during magnesium sulfate administration for preterm labor
There were no significant differences in serum Mg and Ca levels during MgSO4 administration for preterm labor compared to the before and after administration of Mgso4, and only I-Ca levels were not substantially changed.
Zinc as a Gatekeeper of Immune Function
Molecular mechanisms underlying the development of a pro-inflammatory phenotype during zinc deficiency are reported, and links between altered zinc homeostasis and disease development are described, ensuring the benefits of zinc supplementation for a malfunctioning immune system become clear.
The Kinetic Response of the Proteome in A549 Cells Exposed to ZnSO4 Stress
This study further elucidates the understanding of dynamic nature of the cellular response to zinc stress and the mechanism of zinc homeostasis and identified 50 differentially expressed proteins which are predominantly involved in metabolic process, cellular process or developmental process, and function as binding, catalytic activity or structural molecule activity.
Zinc Signals in Cellular Functions and Disorders
This book extensively reviews the field from the basic aspects to the crucial roles of zinc signaling in biological processes, discussing the future directions and questions at both the molecular and the physiological level.
