The Level of Anti-Polyethylene Glycol (PEG) Immunoglobulin G Antibodies in Human Serum Does Not Correlate with Efficiency of PEGylated Nanoparticle Uptake by Monocytes.

The presence of anti-polyethylene glycol (PEG) antibodies can limit the clinical efficacy of PEGylated drugs and cause anaphylactic reactions in patients. Monocytes/macrophages are effector cells involved in IgG-mediated passive systemic anaphylaxis. We studied the influence of human blood serum on the efficiency of uptake of PEGylated nanoparticles by human blood monocytes.

Radiolabeled Complex of Antimicrobial Peptides UBI29-41 and UBI18-35 Labeled with Tc for Differential Diagnosis of Bone Infection of the Limbs.

We studied an original radiolabeled complex of antimicrobial peptides UBI29-41 and UBI18-35, ubiquicidin derivatives, for distinguishing between bacterial and aseptic inflammation. For radiolabeling of the peptides with technetium-99m, a bifunctional chelating agent succinimide-1-yl 6-(bis(pyridin-2-ylmethyl)amino)hexanoate was used. The obtained complexes Тс-DPAH-UBI29-41 and Тс-DPAH-UBI18-35 had radiolabeling yield >80% and radiochemical purity >96%.

Liver Hemostasis by Using Cold Plasma.

Surgical resection is associated with blood loss and bacterial infections. The aim of this study was to evaluate the effectiveness of cold plasma treatment during liver resection. Thirty adult male Wistar rats were divided randomly into 2 groups.

[Morphofunctional Changes of Spleen After Hemostasis by Nonequilibrium Plasma].

Background: Heavy bleeding is developed in case of spleen injury. It often leads to death. At present the search and development of new methods for hemostasis of spleen bleeding continues.
