ELECTROCHEMICAL MEASUREMENTS OF CELL POPULATIONS
Annals of the New York Academy of Sciences, 1981Determination of cell growth was carried out by a polarographic system. The system was constructed of two platinum electrodes, a saturated calomel electrode, and a thermistor electrode. Responses of the system to the dissolved oxygen, pH, and temperature were examined. Cell growth of S. cerevisiae and M.

Measurement of Autophagy in Cells and Tissues
2010Two major proteolysis systems, the ubiquitin-proteasome system, and the autophagy-lysosome system, contribute to degradation of various types of protein and/or protein aggregates. In general, the autophagy-lysosome system is involved in bulk intracellular degradation of proteins and organelles, while the ubiquitin-proteasome system is selective. During

Force Measurements for Cancer Cells
2017During cytoskeleton remodeling, cancer cells generate force at the plasma membrane that originates from chemical motors (e.g., actin). This force (pN) and its time course reflect the on and off-rates of the motors. We describe the design and calibration of a force-measuring device (i.e., optical tweezers) that is used to monitor this force and its time

Measurements of ATP in mammalian cells
Methods, 2002Levels of phosphorylated adenosine nucleotides, including the universal energy carrier adenosine 5(')-triphosphate (ATP) and its metabolites adenosine 5(')-diphosphate (ADP) and adenosine 5(')-monophosphate (AMP), define the energy state in living cells and are dependent mainly on mitochondrial function.

Measuring Ca2+ in Living Cells
2019Measuring free Ca2+ concentration ([Ca2+]) in the cytosol or organelles is routine in many fields of research. The availability of membrane permeant forms of indicators coupled with the relative ease of transfecting cell lines with biological Ca2+ sensors have led to the situation where cellular and subcellular [Ca2+] is examined by many non ...

Measuring cells in phytoplankton images
2015 International Conference on High Performance Computing & Simulation (HPCS), 2015Phytoplankton is a quality element for determining the ecological status of transitional water ecosystems. In routine analysis, bio-volume and surface area of phytoplankton are the most studied morphometric descriptors. Bio-volume can be estimated by comparing the algae with similar three-dimensional geometric forms and determining their volume, by ...

Rotation Measurements of Tethered Cells
2017Direct observation of the rotation of tethered cells using optical microscopy is a simple method to examine dynamics of the bacterial flagellar motor. The rotational speed indicates not only the existence of the rotary motor, but also approximate number of stators that are torque-generating units in a motor. Since "run" and "tumble" of the peritrichous

Measurement of apoptotic cells in peripheral blood
Cytometry, 1995AbstractThe measurement of apoptosis in peripheral blood might represent a useful tool in acquired immunodeficiency syndrome (AIDS) and cancer research. Among the many assays that are currently used to identify apoptotic leukocytes, flow cytometric methods are the most valuable in terms of rapidity, simplicity, and level of analytical detail. Some flow

Measurements of human epidermal cells
Archiv f�r Dermatologische Forschung, 1972Corresponding to different effects of fixing materials used, the statistical results of comparative measurements of healthy human epidermis were presented individually. Because of the modest amount of samples available, it is not possible to draw absolute conclusions from the results.

Measurement of Autophagic Activity in Mammalian Cells
Current Protocols in Cell Biology, 2012AbstractMacroautophagy (referred to herein as autophagy) is a process in which cells engulf portions of cytoplasm in double‐membrane vesicles called autophagosomes. These autophagosomes can also capture protein oligomers associated with neurodegenerative diseases, infectious agents (like bacteria), and even organelles (like mitochondria ...
