The influence of osmotic stress on the content of calcium ions in the red beet vacuoles and on the transport activity of tonoplast proton pumps [PDF]
Journal of Stress Physiology & Biochemistry, 2012 The contents of calcium ions in the isolated vacuoles and in intact red beets under the conditions of dormancy and osmotic stress was determined. It is demonstrated that the content of calcium ions in the red beet vacuoles not exposed to osmotic stress ...

mBio, 2015 The enteropathogenic bacterium Shigella flexneri uses a type 3 secretion apparatus (T3SA) to transfer proteins dubbed translocators and effectors inside host cells, inducing bacterial uptake and subsequent lysis of the entry vacuole.

Cytoplasmic streaming in plant cells: the role of wall slip [PDF]
J. R. Soc. Interface 2012 9, 1398-1408, 2012 We present a computer simulation study, via lattice Boltzmann simulations, of a microscopic model for cytoplasmic streaming in algal cells such as those of Chara corallina. We modelled myosin motors tracking along actin lanes as spheres undergoing directed motion along fixed lines.

Pelodictyon phaeoclathratifovme sp. nov., a new brown-colored member of the Chlorobiaceae forming net-like colonies [PDF]
, 1989 A new strain of the green sulfur bacteria was isolated from the monimolimnion of Buchensee (near Radolfzell, Lake Constance region, FRG). Single cells were rod-shaped, nonmotile and contained gas vacuoles. Typical net-like colonies were formed by ternary

The phospholipid flippase ATP8B1 is required for lysosomal fusion in macrophages
Cell Biochemistry and Function, Volume 40, Issue 8, Page 914-925, December 2022., 2022 Abstract ATP8B1 is a phospholipid flippase and member of the type 4 subfamily of P‐type ATPases (P4‐ATPase) subfamily. P4‐ATPases catalyze the translocation of phospholipids across biological membranes, ensuring proper membrane asymmetry, which is crucial for membrane protein targeting and activity, vesicle biogenesis, and barrier function.

Bondi accretion onto cosmological black holes [PDF]
Phys. Rev. D15, vol. 87, 04400(2013), 2012 In this paper we investigate a steady accretion within the Einstein-Straus vacuole, in the presence of the cosmological constant. The dark energy damps the mass accretion rate and --- above certain limit --- completely stops the steady accretion onto black holes, which in particular is prohibited in the inflation era and after (roughly) $10^{12}$ years

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022 Fifteen new dinuclear arene‐ruthenium (II)‐BODIPY conjugates were synthesized. Despite a fluorescence quenching effect, these conjugates can be used as fluorescent tracers. Their antiparasitic activity but also their toxicity against healthy human foreskin fibroblasts (HFFs) was reduced compared to the parent ruthenium compounds.

Pseudomonas aeruginosa utilizes the type III secreted toxin ExoS to avoid acidified compartments within epithelial cells. [PDF]
PLoS ONE, 2013 Invasive Pseudomonas aeruginosa (PA) can enter epithelial cells wherein they mediate formation of plasma membrane bleb-niches for intracellular compartmentalization.
