Fertilized peanut (Arachis hypogaea L.) ovaries develop into aerial gynophores known as pegs, which are supposed to endure delayed penetration into the soil (pegging) caused by increased surface soil strength promoted by ...

mPEG-aldehydes and activated mPEG-carboxylic acids on which the polymer and the reactive functional group are separated by aliphatic chains of different lengths, are well known reagents of widespread application in PEGylation ...

The vapor pressure of H2O(1)-polyethylene glycol 400(2)-polyethylene glycol 6000(3) solutions was evaluated experimentally in a temperature range between 318.15 and 348.15 K and in a broad range of concentrations. The ...

Sterosomes (STEs), a new and promising non-phospholipidic liposome platform based on palmitic acid (PA) and cholesterol (Chol) mixtures, need to have polyethylene glycol (PEG) chains grafted to their surface in order to ...

Nanostructures for co-encapsulation of chemotherapeutic drugs have been widely studied for the last years due to its important advantages, e.g. improved bioavailability and cellular uptake, increased solubility of drugs, ...

The present study reports the production and characterization of PEG-coated silica nanoparticles (SiNP-PEG) containing insulin for oral administration. High (PEG 20,000) and low (PEG 6000) PEG molecular weights were used ...

The Golden-headed lion tamarin (Leontopithecus chrysomelas) is an endemic monkey to Atlantic Forest. Nowadays, they are classified as threatened of extinction. Efforts on its conservation cover in situ and ex situ programs, ...

psi-Condensation of DNA fragments of about 4 kbp was induced by poly(ethylene glycol) (PEG), with degrees of polymerization ranging from 45 to 182, and univalent salt (NaCl). Using circular dichroism spectroscopy, we were ...
