ENERGY BALANCE IN RED CELL INTERACTIONSa

Annals of the New York Academy of Sciences, 1983
Experiments were performed to elucidate the balance of energies involved in the formation of red blood cell (RBC) aggregates and in their disaggregation. In order to achieve a mean stable rouleau formation, the aggregating energy provided by macromolecular binding to the cell membrane must overcome the disaggregation energy of electrostatic repulsion ...

Balancing ATP in the cell

Nature Structural Biology, 1996
The ultimate control over cellular energy is provided by a creatine kinase. The newly determined crystal structure of mitochondrial creatine kinase indicates a role in channelling components from mitochondria to cytoplasm.

Optimal Scheduling for Active Cell Balancing

2019 IEEE Real-Time Systems Symposium (RTSS), 2019
Active cell balancing is performed to minimize the variation in the charge levels of the individual cells in a high-power battery pack, to improve its usable capacity. The process of charge equalization is carried out by scheduling pairs of cells to transfer charge over a hardware circuit.

Phagocytosis of apoptotic cells: a matter of balance

Cellular and Molecular Life Sciences CMLS, 2005
Efficient clearance of apoptotic cells is required to control homeostasis in normal and pathological circumstances, and inappropriate clearance of cell corpses may lead to autoimmune diseases and inflammation. The multiplicity of phagocytotic mechanisms points to the relevance of removing apoptotic cells.

Voltage Balance and Energy Balance in an Electrolytic Cell

1985
Electrolytic current will flow from the anode to the cathode in electrolytic solution in a cell by means of transport of both cations and anions to the respective directions of the electric field. The mechanism of conduction in electrolytic solution differs from that in a metallic conductor in which free electrons move in the inverse direction of flow ...

Iron and its sensitive balance in the cell

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 2001
Iron is vital in life because it is an important component of molecules that undergoes redox reactions or transport oxygen. However, the existence of two stable and inter-convertible forms of iron, iron(III) and iron(II), makes possible one electron being transferred to or captured from other species to form radicals.

Stem cell: balancing aging and cancer

The International Journal of Biochemistry & Cell Biology, 2005
Stem cells are defined by their self-renewing capacity and the ability to differentiate into one or more cell types. Stem cells can be divided, depending on their origin, into embryonic or adult. Embryonic stem cells derive from early stage embryos and can give rise to cells from all three germ layers.

Topological Regulation of Lipid Balance in Cells

Annual Review of Biochemistry, 2014
Lipids are unevenly distributed within and between cell membranes, thus defining organelle identity. Such distribution relies on local metabolic branches and mechanisms that move lipids. These processes are regulated by feedback mechanisms that decipher topographical information in organelle membranes and then regulate lipid levels or flows.

MK2 balances inflammation and cell death

Nature Cell Biology, 2017
The cytokine tumour necrosis factor (TNF) and the toll-like receptors (TLRs) coordinate immune responses by activating inflammatory transcriptional programs, but these signals can also trigger cell death. Recent studies identify the MAP kinase substrate MK2 as a key player in determining whether cells live or die in response to TNF and TLR signalling.
