Metric Expansion from Microscopic Dynamics in an Inhomogeneous Universe [PDF]

Communications in Theoretical Physics 54 (3) pp. 477-483 (2010), 2010
Theories with ingredients like the Higgs mechanism, gravitons, and inflaton fields rejuvenate the idea that relativistic kinematics is dynamically emergent. Eternal inflation treats the Hubble constant H as depending on location. Microscopic dynamics implies that H is over much smaller lengths than pocket universes to be understood as a local space ...

The role of dynamin-related proteins in vacuole biogenesis in fission yeast (Schizosaccharomyces pombe) : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Biochemistry at Massey University, Palmerston North, New Zealand [PDF]

, 2008
Dynamins are GTPases concerned with membrane tubulation and scission (Praefcke and McMahon, 2004). In the fission yeast, Schizosaccharomyces pombe, the dynamin-related proteins (DRPs) Vps1 and Dnm1 act redundantly in peroxisome biogenesis (Jourdain et al.

KCS1 and VIP1, the genes encoding yeast phosphoinositol pyrophosphate synthases, are required for Ca2+‐mediated response to dimethylsulfoxide (DMSO)

FEBS Open Bio, EarlyView.
Ca2+‐mediated response to DMSO was investigated in Saccharomyces cerevisiae cells expressing Ca2+‐dependent aequorin. Cell exposure to DMSO induced a cytosolic Ca2+ wave dependent on the integrity of the Cch1/Mid1 channel. Deletion of KCS1 or VIP1 genes encoding the phosphoinositol pyrophosphate (PP‐IP) synthases suppressed the DMSO‐induced Ca2 ...

A companion to the preclinical common data elements and case report forms for neuropathology studies in epilepsy research. A report of the TASK3 WG2 Neuropathology Working Group of the ILAE/AES Joint Translational Task Force

Epilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force initiated the TASK3 working group to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.

Controlled Activity of the Salmonella Invasion-Associated Injectisome Reveals Its Intracellular Role in the Cytosolic Population

mBio, 2017
The Salmonella invasion-associated type III secretion system (T3SS1) is an essential virulence factor required for entry into nonphagocytic cells and consequent uptake into a Salmonella-containing vacuole (SCV).

Specific histamine regulating activity of surface‐modified yeast vacuoles by histamine‐ binding protein and its immune‐enhancing effect

Microbial Biotechnology, 2022
We aimed to develop a biocompatible material that could enhance weakened immunity and control histamine in vivo. Histamine‐binding protein (HBP) vacuoles have a mechanism of action that directly binds to the histamine molecule.

Vtc4 Promotes the Entry of Phagophores into Vacuoles in the Saccharomyces cerevisiae Snf7 Mutant Cell

Journal of Fungi, 2023
Endocytosis and autophagy are the main pathways to deliver cargoes in vesicles and autophagosomes, respectively, to vacuoles/lysosomes in eukaryotes. Multiple positive regulators but few negative ones are reported to regulate the entry of vesicles and ...

Review on exact and perturbative deformations of the Einstein-Straus model: uniqueness and rigidity results [PDF]

, 2013
The Einstein-Straus model consists of a Schwarzschild spherical vacuole in a Friedman-Lema\^{\i}tre-Robertson-Walker (FLRW) dust spacetime (with or without \Lambda). It constitutes the most widely accepted model to answer the question of the influence of large scale (cosmological) dynamics on local systems.

A New Type of Exact Arbitrarily Inhomogeneous Cosmology: Evolution of Deceleration in the Flat Homogeneous-On-Average Case [PDF]

Journal of Cosmology and Astroparticle Physics, JCAP01(2012)043, 2012
A new method for constructing exact inhomogeneous universes is presented, that allows variation in 3 dimensions. The resulting spacetime may be statistically uniform on average, or have random, non-repeating variation. The construction utilises the Darmois junction conditions to join many different component spacetime regions.
