Background and Aim: Shampoos are surfactant systems to clean hair and body. Two kinds of surfactants are generally used in shampoo formulations: anionic and amphoteric. These agents, especially anionic ones may cause skin irritation and dryness after bathing. So, using a simple and fast method to determine the types and concentrations of surfactants can help to choose a product with high effica...

Despite intense research in FLP chemistry, nothing is known about monomolecular anionic FLPs and/or complexes thereof. Herein, synthesis and reaction of the first anionic FLP complex is described using [(OC)5W{(Me3Si)2HCP(H)OLi(12-crown-4)}], Cy2BCl and subsequent deprotonation by KHMDS. The obtained anionic FLP complex reacts readily with CO2 in a concerted manner.

The distribution of anionic binding sites has been investigated in the isolated Golgi complex using cationic ferritin. The greatest density of anionic sites occurs on the tubular network and small vesicles, and this binding is accompanied by increased levels of galactosyltransferase activity. The density of anionic sites on the cisternae is less than on the tubules and shows anisotropic distrib...

The anionic [2,3] sigmatropic Wittig rearrangements of deprotonated 4-hetera-1-pentenes and the anionic [3,3] sigmatropic Cope rearrangements of 3-substituted-1,5-hexadienes were explored by using density functional theory calculations. While the deprotonated anionic 3-hydroxy-1,5 hexadiene (2a), 3-thiohydroxy-1,5-hexadiene (2c), and 3-formamidyl-1,5-hexadiene (2d) Cope substrates undergo conce...

Anionic states of nucleic acid bases are involved in DNA damage by low-energy electrons and in charge transfer through DNA. Previous gas phase studies of free, unsolvated nucleic acid base parent anions probed only dipole-bound states, which are not present in condensed phase environments, but did not observe valence anionic states, which for purine bases are thought to be adiabatically unbound...

In this experiment, we developed anionic ternary complexes for effective and safe ocular gene delivery. Ternary complexes were constructed by coating plasmid DNA (pDNA)/polyethylenimine (PEI) complex with anionic polymers such as γ-polyglutamic acid (γ-PGA) and chondroitin sulfate (CS). The cationic pDNA/PEI complex showed high gene expression on the human retinal pigment epithelial cell line, ...

Anisotropy of anionic sites on plasma membranes has been implicated in contact phenomena at cell surfaces (16, 17). Recent evidence indicates that charge anisotropy may be important among intracellular membranes also, since distribution of anionic sites has been related to structural organization of mitochondrial membranes (8). The use of cationic ferritin has been introduced by Danon et al. (2...
