Background: Glioblastoma (GBM) is one of the most aggressive tumors, health-threatening, and resistant to available treatment approaches for people worldwide. Objectives: This study aimed evaluate effects swimming training a supplement comprising four nanoliposome herbal extracts in rat model with mid-brain tumor. Methods: In this experimental study, 56-male-Wistar rats (230 ± 20 g) were divide...

BACKGROUND Liposomes can be modified with different ligands to control their biological properties, such as longevity, targeting ability, and intracellular penetration, in a desired fashion. The aim of this study was to modify liposomes with a novel mannosylated polyethylene glycol-phosphatidylethanolamine (M-PEG-PE) ligand to achieve active targeted gene delivery. METHODS Rat Kupffer cells w...

Iontophoresis is a promising technique for enhancing transdermal administration of charged drugs. However, conventional iontophoresis is not sufficient for effective delivery of large, hydrophilic, or electrically neutral molecules. In this study, we utilized charged liposomes as carriers, focused on a transfollicular route for delivery of the liposomes, and optimized iontophoretic conditions a...

The recent discovery of dideoxymycobactin (DDM) as a ligand for CD1a demonstrates how a nonribosomal lipopeptide antigen is presented to T cells. DDM contains an unusual acylation motif and a peptide sequence present only in mycobacteria, but its discovery raises the possibility that ribosomally produced viral or mammalian proteins that commonly undergo lipidation might also function as antigen...

Fifteen rabbits were used to assess the effect of Lipo-PGE1 on neovascularization. Merocel(®) and Alloderm(®) of the same size were implanted separately under the back skin to act as matrices for vessel growth. Lipo-PGE1 was injected intravenously for 2 weeks in an experimental group of eight rabbits, and they were compared with a control group of seven untreated animals. Blood flow was measure...

Primary islet nonfunction due to an instant blood mediated inflammatory reaction (IBMIR) leads to an increase in donor islet mass required to achieve euglycemia. In the presence of thrombin, thrombomodulin generates activated protein C (APC), which limits procoagulant and proinflammatory responses. In this study, we postulated that liposomal formulations of thrombomodulin (lipo-TM), due to its ...

Extracellular enzymes from alfalfa (Medicago sativa L.) involved in the degradation of nodulation (Nod) factors could be distinguished by their different cleavage specificities and were separated by lectin affinity chromatography. A particular glycoprotein was able to release an acylated lipo-disaccharide from all tested Nod factors having an oligosaccharide chain length of four or five residue...

PEGylated nanoparticles and macromolecules are increasingly used in cancer imaging and anticancer treatment. The role of receptor-mediated endocytosis in the efficacy of these agents, however, has not been clearly defined. Here, we developed a matched pair of endocytic and nonendocytic receptors to directly and unambiguously assess this issue. The ligand-binding domains of the low-density lipop...

Antimicrobial peptides (AMP) which have been identified in almost all groups of organisms, are the small cationic molecules that recognize the pathogen associated molecular patterns of the microbes. In chicken two main AMPs that play significant roles in bolstering the innate immunity are gallinacins and fowlicidins, which are the functional analogues of the mammalian beta-defensins and catheli...

Lipo-oligomers have been proven as potent siRNA carriers based on stable electrostatic and hydrophobic complex formation and endosomal membrane destabilization. Although high stability of siRNA polyplexes is desirable in the extracellular space and cellular uptake, intracellular disassembly is important for the cytosolic release of siRNA and RNA-induced silencing complex formation. To improve t...
