A wide range of cellular activities including protein folding and cell secretion, such as neurotransmission or insulin release, are all governed by intracellular pH homeostasis, underscoring the importance of pH on critical life processes. Nano- scale pH measurements of cells and biomolecules therefore hold great promise in understanding a plethora of cellular functions, in addition to disease ...
BACKGROUND Clinical efficacy of thrombolytic drugs is limited by lack of specific delivery and requires large therapeutic doses which increase toxicity. Encapsulating these drugs in temperature-sensitive liposomes and applying hyperthermia to deliver thrombolytic agents locally to thrombus might theoretically favourably alter the therapeutic window. The objectives of this study were to formulat...
the main objective of this study was to investigate biocompatibility and provide in vivo pharmacological and toxicological evidence for further investigation of the possibility of ph sensitive ion exchange resin microsphere for clinical utilizations. acute toxicity study and general pharmacological studies were conducted on the ph sensitive ion exchange resin microsphere we prepared. the genera...
Using a liposome-binding assay, we investigated the requirements for activation of herpes simplex virus (HSV) into a state capable of membrane interaction. Virions were mixed with liposomes along with the ectodomain of one of three gD receptors (HVEMt, nectin-1t, or nectin-2t) and incubated under different pH and temperature conditions. Virions failed to associate with liposomes in the presence...
Background: This study is an attempt to investigate the effect of nano-liposome containing voriconazole on voriconazole-resistant A. flavus strains on the one hand, and to consider the expression of cyp51A and MDR1genes, regarded as important genes involved in the development of resistance to triazoles before and after voriconazole and voriconazole-loaded nano-liposomes exert their effects, on ...
Semliki Forest virus (SFV) infects cells by an acid-dependent membrane fusion reaction catalyzed by the virus spike protein, a complex containing E1 and E2 transmembrane subunits. E1 carries the putative virus fusion peptide, and mutations in this domain of the spike protein were previously shown to shift the pH threshold of cell-cell fusion (G91A), or block cell-cell fusion (G91D). We have use...
We encapsulated cisplatin into stealth pH-sensitive liposomes and studied their stability, cytotoxicity and accumulation in a human small-cell lung carcinoma cell line (GLC4) and its resistant subline (GLC4/CDDP). Since reduced cellular drug accumulation has been shown to be the main mechanism responsible for resistance in the GLC4/CDDP subline, we evaluated the ability of this new delivery sys...
