Objectives Tanacetum species are traditionally used as insecticide, and externally wound healer as well as for anti-inflammatory and antihistaminic properties. The in vivo wound-healing and anti-inflammatory potential of four Tanacetum species, Tanacetum argenteum (Lam.) Willd. subsp. argenteum (TA), Tanacetum heterotomum (Bornm.) Grierson (TH), Tanacetum densum (Lab.) Schultz Bip. subsp. sivas...

The specific activity of uridine diphosphate N-acetylglucosamine-4-epimerase increases during spherulation of Physarum polycephalum, a process that involves the synthesis of galactosamine walls. This increase is prevented by the addition of cycloheximide.

We have previously observed the apparent displacement of microfilaments over microtubules in the backbone structure of permeabilized flagellates of Physarum polycephalum upon addition of ATP (Uyeda, T. Q. E , and M. Furuya. 1987. Protoplasma.

Biomechanical Signaling Physarum polycephalum, a slime mold with one cell and no brain, is remarkable new model for understanding basal cognition. Its living material deforms its own structure to interact the objects around it. In article number 2008161, Michael Levin co-workers show that senses strain in substrate, using biomechanical signaling assess environment express preferences as directi...

The slime mould Physarum polycephalum is known to construct protoplasmic transport networks which approximate proximity graphs by foraging for nutrients during its plasmodial life cycle stage. In these networks, nodes are represented by nutrients and edges are represented by protoplasmic tubes. These networks have been shown to be efficient in terms of length and resilience of the overall netwo...

An acidic nucleolar phosphoprotein with a subunit M(r) of 70,000 was purified as an apparent dimer of 139,000 from isolated nuclei of the slime mold Physarum polycephalum. The protein was purified without the aid of strong dissociating agents after its selective phosphorylation in isolated nuclei by a polyamine-mediated reaction. Its amino acid composition resembled that of a nucleolar phosphop...

Mitochondrial RNAs in the acellular slime mold Physarum polycephalum contain nucleotides that are not encoded in the mitochondrial genes from which they are transcribed. These site-specific changes are quite extensive, comprising ~4% of the residues within mRNAs and ~2% of rRNAs and tRNAs. These "extra" nucleotides are added co-transcriptionally, but the means by which this is accomplished have...

Carbon nanotubes (CNTs) offer attractive opportunities due to their physical, electrical, mechanical, optical, and thermal properties. They are used in a wide range of applications found numerous consumer products. On the downside, increasing presence environment poses potential threats living organisms ecosystems. The aim this study was evaluate toxicity double-walled carbon (DWCNTs) on new mo...
