Journal of Cell Biology, 2018 Autophagy is a catabolic pathway that delivers intracellular material to the mammalian lysosomes or the yeast and plant vacuoles. The final step in this process is the fusion of autophagosomes with vacuoles, which requires SNARE proteins, the homotypic ...

Identification of Fis1 Interactors in Toxoplasma gondii Reveals a Novel Protein Required for Peripheral Distribution of the Mitochondrion [PDF]
, 2020 Toxoplasma gondii’s single mitochondrion is very dynamic and undergoes morphological changes throughout the parasite’s life cycle. During parasite division, the mitochondrion elongates, enters the daughter cells just prior to cytokinesis, and undergoes ...

Synchrotron radiation microtomography of brain hemisphere and spinal cord of a mouse model of multiple sclerosis revealed a correlation between capillary dilation and clinical score [PDF]
J. Comp. Neurol. (2019), 2018 Multiple sclerosis is a neurological disorder in which the myelin sheaths of axons are damaged by the immune response. We report here a three-dimensional structural analysis of brain and spinal cord tissues of a mouse model of multiple sclerosis, known as experimental autoimmune encephalomyelitis (EAE).

Influence of Electromagnetic Field on Hyperbolically Symmetric Source [PDF]
Eur. Phys. J. Plus 136, 857 (2021), 2021 We pursue a coherent analysis of hyperbolically symmetric static sources by extending the work of Herrera \cite{26} to the case of electromagnetic field. We deeply analyze the impact of such a force on the physical characteristics of the hyperbolically symmetric spacetime under consideration.

Efficient imaging and computer vision detection of two cell shapes in young cotton fibers
Applications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022 Abstract Premise The shape of young cotton (Gossypium) fibers varies within and between commercial cotton species, as revealed by previous detailed analyses of one cultivar of G. hirsutum and one of G. barbadense. Both narrow and wide fibers exist in G. hirsutum cv.

Is the cluster of galaxies "Abell 194" surrounded by an Einstein-Straus vacuole? [PDF]
Astron.Astrophys. 440 (2005) L41-L43, 2005 It is suggested that an ``Einstein-Straus vacuole'' -- a region of space time with a metric obtained by solving the equations of general relativity of a mass condensation in an expanding universe with vanishing cosmological constant -- surrounds the cluster of galaxies ``Abell 194''.

Role of vacuoles in phosphorus storage and remobilization.
Journal of Experimental Botany, 2017 Vacuoles play a fundamental role in storage and remobilization of various nutrients, including phosphorus (P), an essential element for cell growth and development. Cells acquire P primarily in the form of inorganic orthophosphate (Pi). However, the form

The Vacuole Model: New Terms in the Second Order Deflection of Light [PDF]
JCAP 1102:028,2011, 2010 The present paper is an extension of a recent work (Bhattacharya et al. 2010) to the Einstein-Strauss vacuole model with a cosmological constant, where we work out the light deflection by considering perturbations up to order M^3 and confirm the light bending obtained previously in their vacuole model by Ishak et al. (2008).

Acid digestion and symbiont: Proton sharing at the origin of mitochondriogenesis?
BioEssays, Volume 45, Issue 1, January 2023., 2023 ADMit hypothesis for the origin of eukaryotes. A bacterial symbiont became associated with a protophagocytic host that captured prey with membrane processes. The symbiont cooperated to kill and digest the prey with reactive oxygen species and the acidification of the microenvironment.
