Pattern formation at cellular membranes by phosphorylation and dephosphorylation of proteins [PDF]
, 2016 We consider a classical model on activation of proteins, based in two reciprocal enzymatic biochemical reactions. The combination of phosphorylation and dephosphorylation reactions of proteins is a well established mechanism for protein activation in ...

3D Computational Modeling of Bleb Initiation Dynamics
Frontiers in Physics, 2021 Blebbing occurs in cells under high cortical tension when the membrane locally detaches from the actin cortex, resulting in pressure-driven flow of the cytosol and membrane expansion. Some cells use blebs as leading edge protrusions during cell migration,

The cytoplasm of living cells: A functional mixture of thousands of components [PDF]
, 2005 Inside every living cell is the cytoplasm: a fluid mixture of thousands of different macromolecules, predominantly proteins. This mixture is where most of the biochemistry occurs that enables living cells to function, and it is perhaps the most complex ...

Magnetic wire as stress controlled micro-rheometer for cytoplasm viscosity measurements [PDF]
, 2018 We review here different methods to measure the bulk viscosity of complex fluids using micron-sized magnetic wires. The wires are characterized by length of a few microns and diameter of a few hundreds of nanometers.

Parathyroid Adenoma Completely Impacted within the Thyroid Gland: A Case Report [PDF]
Journal of Clinical and Diagnostic Research, 2016 Ectopic parathyroid adenoma can be seen in various locations. Sometimes ultrasound and even fine needle aspiration studies cannot distinguish this lesion from thyroid lesions. A 29-year-old woman with a prominent nodule of left thyroid lobe was referred

Confocal Raman data analysis enables identifying apoptosis of MCF-7 cells caused by anticancer drug paclitaxel [PDF]
, 2013 Confocal Raman microscopy is a noninvasive, label-free imaging technique used to study apoptosis of live MCF-7 cells. The images are based on Raman spectra of cells components, and their apoptosis is monitored through diffusion of cytochrome c in ...
