Temperature-induced changes in the hydroxy and non-hydroxy fatty acid-containing sphingolipids abundant in the surface membrane of Tetrahymena pyriformis NT-1.

open access: yesJournal of Lipid Research, 1984
Sphingolipids make up 30 to 40 mole % of the phospholipids found in the surface membrane of Tetrahymena pyriformis NT-1. We have identified the two major classes as non-hydroxy fatty acid-containing ceramide-2-aminoethylphosphonate (NCAEP) and alpha ...

Studies on the relation between heme and nucleic acid syntheses in erythroid cell. 3. Nucleolus of erythroblast, changes in relation with cell specialization [PDF]

open access: yes, 1969
The disappearance of nucleolus has been traced in the rat erythroid cells in relation with the cell specialization under varying conditions, i. e. in anemia with or without treatment by bromouracil and aminopterin.

Hybrid Molecules Containing Methotrexate, Vitamin D, and Platinum Derivatives: Synthesis, Characterization, In Vitro Cytotoxicity, In Silico ADME Docking, Molecular Docking and Dynamics

open access: yesChemistry &Biodiversity, Volume 22, Issue 1, January 2025.
Abstract Designing hybrid‐based drugs is one promising strategy for developing effective anticancer drugs that explore combination therapy to enhance treatment efficacy, overcome the development of drug resistance, and lower treatment duration. Bisphosphonates and Vitamin D are commonly administered drugs for the treatment of bone diseases and the ...

Listeria monocytogenes virulence factor Listeriolysin O favors bacterial growth in co-culture with the ciliate Tetrahymena pyriformis, causes protozoan encystment and promotes bacterial survival inside cysts

open access: yesBMC Microbiology, 2010
Background The gram-positive pathogenic bacterium Listeria monocytogenes is widely spread in the nature. L. monocytogenes was reported to be isolated from soil, water, sewage and sludge. Listeriolysin O (LLO) is a L. monocytogenes major virulence factor.

Eco‐phenotypic feedback loops differ in multistressor environments

open access: yesEcology, Volume 106, Issue 1, January 2025.
Abstract Natural communities are exposed to multiple environmental stressors, which simultaneously impact the population and trait dynamics of the species embedded within these communities. Given that certain traits, such as body size, are known to rapidly respond to environmental change, and given that they can strongly influence the density of ...

A biosensor for cadmium based on bioconvective patterns [PDF]

open access: yes
An 'in vitro' method for monitoring cadmium, one of the most lethal bivalent heavy metals, can detect biologically active levels. The effects of cadmium tend to concentrate in protozoa far above natural levels and therein begin transferring through ...

Unveiling the Anticancer Potential of Formylbenzyl‐N,N‐Dimethylmethanaminium‐Based Ionic Liquids via Cheminformatics Approaches

open access: yesJournal of Chemistry, Volume 2025, Issue 1, 2025.
Inhibiting tubulin polymerisation, an essential step for cell proliferation, can control cell division. Our in silico study aims to screen out the derivatives of 1,3‐benzodioxole‐tagged formylbenzyl‐N, N‐dimethylmethanaminium ionic liquid for their potential as anticancer agents.

Positional distribution of fatty acids in the glycerophospholipids of Tetrahymena pyriformis.

open access: yesJournal of Lipid Research, 1979
The positional distributions of the fatty acids in the major glycerophospholipids of Tetrahymena pyriformis W were analyzed. A comparison was made of the acyl distributions in normal and ergosterol-grown cells.

Acute Toxicities of Bromophenols to Alga and Daphina: Comparative Species Sensitivity Distribution Between Standard and Dietary Supplementation Tests

open access: yesJournal of Toxicology, Volume 2025, Issue 1, 2025.
Bromophenols are synthesized chemicals that are widely used in various industrial activities and are also naturally produced by marine algae as secondary metabolites, including 2,4‐dibromophenol (2,4‐DBP), 2,6‐dibromophenol (2,6‐DBP), and 2,4,6‐tribromophenol (2,4,6‐TBP).
