Ions, cell volume, and apoptosis [PDF]
Proceedings of the National Academy of Sciences, 2000 Programmed cell death culminating in apoptosis is responsible for normal tissue homeostasis and has increasingly been implicated in mediating pathological cell loss (1–3). Apoptosis is accompanied by characteristic morphological changes, including cell body and nuclear condensation, chromatin margination, and the formation of membrane-bound remnants ...

Cell Volume Regulation in the Epidermis
Cellular Physiology and Biochemistry, 2021 In order to cope with external stressors such as changes in humidity and temperature or irritating substances, the epidermis as the outermost skin layer forms a continuously renewing and ideally intact protective barrier. Under certain circumstances, this barrier can be impaired and epidermal cells have to counteract cell swelling or shrinkage induced ...

Cell AT-Models for Digital Volumes [PDF]
, 2009 In [4], given a binary 26-adjacency voxel-based digital volume V, the homological information (that related to n-dimensional holes: connected components, ”tunnels” and cavities) is extracted from a linear map (called homology gradient vector field) acting on a polyhedral cell complex P(V) homologically equivalent to V.

Cell Volume Regulation in Chondrocytes [PDF]
Cellular Physiology and Biochemistry, 2011 Chondrocytes are the cells within cartilage which produce and maintain the extracellular matrix. Volume regulation in these cells is vital to their function and occurs in several different physiological and pathological contexts. Firstly, chondrocytes exist within an environment of changing osmolarity and compressive loads.

Triggering of Suicidal Erythrocyte Death by Celecoxib
Toxins, 2013 The selective cyclooxygenase-2 (COX-2) inhibitor celecoxib triggers apoptosis of tumor cells and is thus effective against malignancy. The substance is at least partially effective through mitochondrial depolarization.

Brazilian Journal of Medical and Biological Research, 2001 Chick cardiomyocytes, when submitted to hyposmotic swelling, exhibit a partial regulatory volume decrease (RVD). A Ca2+ influx by stretch-activated channels signals a taurine efflux and the RVD at 37°C.

An Improved Cell Volume Analyzer [PDF]
Review of Scientific Instruments, 1971 A cell volume sensing instrument has been built which employs the principle used in the Coulter counter in which a cell changes the impedance of a narrow orifice as it passes through the orifice. An improved transducer utilizes a coaxial flow of the cell suspension inside a sheath of cell-free solution through the orifice, thereby avoiding some ...

Eryptosis: Programmed Death of Nucleus-Free, Iron-Filled Blood Cells
Cells, 2022 Human erythrocytes are organelle-free cells packaged with iron-containing hemoglobin, specializing in the transport of oxygen. With a total number of approximately 25 trillion cells per individual, the erythrocyte is the most abundant cell type not only ...

Triggering of Erythrocyte Death by Triparanol
Toxins, 2015 The cholesterol synthesis inhibitor Triparanol has been shown to trigger apoptosis in several malignancies. Similar to the apoptosis of nucleated cells, erythrocytes may enter eryptosis, the suicidal death characterized by cell shrinkage and cell ...
