  • Publication number: 20240371538
    Abstract: The present invention relates to a method for preparing a radioactive polymerizable solution and the solution per se. The solution is prepared by using a cationic radionuclide with a half-life >5 d that is dissolved in an aqueous solution. The radionuclide is extracted into an organic solvent or monomer solution by using a lipophilic ligand for forming a radioactive complex. The ligand is characterized by a ?2:1 ratio of carbon and/or silicon atoms to specific heteroatoms. If an organic solvent is used for extraction, the organic phase obtained is subsequently diluted in a monomer solution to obtain the radioactive polymerizable solution. The invention further relates to the use of said solution in a method for preparing a radioactive object such as a phantom for medical imaging and the object per se.

  • Publication number: 20230031648
    Abstract: The invention relates to the use of empty liposomes of defined lipid composition or mixtures of empty liposomes of defined lipid composition and to the use of other lipid bilayers or monolayers of defined lipid composition for the treatment and prevention of bacterial infections. It has been found that such liposomes, in particular a two- and a four-component mixture of liposomes comprising cholesterol and sphingomyelin, liposomes consisting of sphingomyelin, liposomes comprising sphingomyelin and phosphatidylcholine, and liposomes comprising cholesterol and phosphatidylcholine efficiently sequestrate a variety of toxins secreted by bacteria, thus preventing binding of bacterial toxins to target cells and toxin-induced lysis of the target cells. Injected intravenously, liposome mixtures prevented death of laboratory mice infected with lethal doses of Staphylococcus aureus or Streptococcus pneumoniae.
