Decrease in stomach contents in the Antarctic minke whale (Balaenoptera bonaerensis) in the Southern Ocean
The Antarctic minke whale (Balaenoptera bonaerensis) is one of the major krill predators in Antarctic waters. A reported decline in energy storage over almost two decades indicates that food availability for the ...

The Co-Delivery of Oxaliplatin Abrogates the Immunogenic Response to PEGylated siRNA-Lipoplex
In vivo application of siRNA/PEGylated cationic liposome complex (lipoplex) is impeded by two main obstacles: cytokine responses and anti-PEG IgM responses to PEGylated siRNA-lipoplex. Here, we...

Article
Argonaute2 is a potential target for siRNA-based cancer therapy for HT1080 human fibrosarcoma
Small interfering RNAs (siRNAs) are small RNA molecules that have a potent, sequence-specific gene silencing effect and therefore show promise for therapeutic use as molecular-targeted drugs for the treatment ...

Complexation of siRNA and pDNA with Cationic Liposomes: The Important Aspects in Lipoplex Preparation
In the last two decades, cationic liposomes have been investigated as vehicles for nucleic acids [plasmid DNA (pDNA) and small interfering RNA (siRNA)] delivery in vitro and in vivo. The formation of cationic ...

Accelerated Blood Clearance Phenomenon Upon Repeated Injection of PEG-modified PLA-nanoparticles
We recently developed prostaglandin E1 (PGE1)-encapsulated nanoparticles, prepared with a poly(lactide) homopolymer (PLA, Mw = 17,500) and monomethoxy poly(ethyleneglycol)-PLA block copolymer (PEG-PLA) (NP-L20). ...

Chapter
Unexpected Reactions by In Vivo Applications of PEGylated Liposomes
PEGylated liposome, a liposome coated with polyethylene glycol (PEG), is understood to be biologically inert and, therefore, a suitable vehicle for in vivo applications. The most successful example is the doxo...

Possible source of the antarctic bottom water in the Prydz Bay Region
It has been inferred that the Prydz Bay region is one of the source regions of Antarctic Bottom Water (AABW) based on rather indirect evidence. In order to examine this inference, we investigate the hydrograph...

Article
Quantitative Analysis of Correlation Between Number of Nuclear Plasmids and Gene Expression Activity After Transfection with Cationic Liposomes
Purpose. A quantitative understanding of the intracellular trafficking of plasmids delivered by nonviral vectors is essential for optimizing vector functions to increase their transfection efficiency. In this st...

Article
Liposome Clearance
The clearance rate of liposomal drugs from the circulation is determined by the rate and extent of both drug release and uptake of liposomes by cells of the mononuclear phagocyte system (MPS). Intravenously in...

Article
Plasma Factor Triggering Alternative Complement Pathway Activation by Liposomes
Several plasma components, such as complement (C) components, play a role in the clearance of liposomes from the circulation. The interactions between liposomes and the C system were investigated in this study...
