Quantum Coherence, Coherent Information and Information Gain in Quantum Measurement [PDF]
EPL (Europhysics Letters) 127 (5), 50004 (2019), 2019 A measurement is deemed successful, if one can maximize the information gain by the measurement apparatus. Here, we ask if quantum coherence of the system imposes a limitation on the information gain during quantum measurement. First, we argue that the information gain in a quantum measurement is nothing but the coherent information or the distinct ...

Quantitative analysis of intra-Golgi transport reveals inter-cisternal exchange for all cargo [PDF]
, 2013 The mechanisms controlling the transport of proteins across the Golgi stack of mammalian and plant cells is the subject of intense debate, with two models, cisternal progression and inter-cisternal exchange, emerging as major contenders. A variety of transport experiments have claimed support for each of these models.

Bio-Protocol, 2015 The plant Golgi apparatus is composed of numerous stacks of cisterna, designated as cis, medial, and trans Golgi cisternae; these stacks move within the cytoplasm along the actin cytoskeleton.

Proteomic identification of S-nitrosylated Golgi proteins: new insights into endothelial cell regulation by eNOS-derived NO. [PDF]
PLoS ONE, 2012 Endothelial nitric oxide synthase (eNOS) is primarily localized on the Golgi apparatus and plasma membrane caveolae in endothelial cells. Previously, we demonstrated that protein S-nitrosylation occurs preferentially where eNOS is localized.

The Golgin Family of Coiled-Coil Tethering Proteins
Frontiers in Cell and Developmental Biology, 2016 The golgins are a family of predominantly coiled-coil proteins that are localized to the Golgi apparatus. Golgins are present in all eukaryotes, suggesting an evolutionary conserved function.

Urothelial plaque formation in post-Golgi compartments. [PDF]
PLoS ONE, 2011 Urothelial plaques are specialized membrane domains in urothelial superficial (umbrella) cells, composed of highly ordered uroplakin particles. We investigated membrane compartments involved in the formation of urothelial plaques in mouse umbrella cells.

Mechanical model of Golgi apparatus [PDF]
arXiv, 2017 The Golgi apparatus has intrigued researchers since its discovery and despite the advances, there are still many open questions in regards to its shape and function. Here, we propose a mechanical model of Golgi apparatus stack and explain its most elementary geometrical properties: the equilibrium number of cisternae, the stack size, and its general ...

Stochastic Model of Maturation and Vesicular Exchange in Cellular Organelles [PDF]
arXiv, 2016 The dynamical organization of membrane-bound organelles along intracellular transport pathways relies on vesicular exchange between organelles and on biochemical maturation of the organelle content by specific enzymes. The relative importance of each mechanism in controlling organelle dynamics remains controversial, in particular for transport through ...

Active Fusion and Fission Processes on a Fluid Membrane [PDF]
, 2000 We investigate the steady states and dynamical instabilities resulting from ``particles'' depositing on (fusion) and pinching off (fission) a fluid membrane. These particles could be either small lipid vesicles or isolated proteins. In the stable case, such fusion/fission events suppress long wavelength fluctuations of the membrane.

Analysis of Coronavirus Envelope Protein with Cellular Automata (CA) Model [PDF]
arXiv, 2022 The reason of significantly higher transmissibility of SARS Covid (2019 CoV-2) compared to SARS Covid (2003 CoV) and MERS Covid (2012 MERS) can be attributed to mutations reported in structural proteins, and the role played by non-structural proteins (nsps) and accessory proteins (ORFs) for viral replication, assembly, and shedding.
