Ethanol/ether soluble apoproteins, comprising 17% of the total recovered surfactant-associated proteins, were isolated from rat lung surfactant and purified by silicic acid chromatography. The protein that eluted in 4:1 chloroform/methanol accounted for greater than 85% of protein in the ethanol/ether soluble fraction and was termed surfactant apoprotein Et (Apo Et). By sodium dodecyl sulfate p...
PURPOSE Quercetin is a potent chemotherapeutic drug. Clinical trials exploring different schedules of administration of quercetin have been hampered by its extreme water insolubility. To overcome this limitation, this study is aimed to develop liposomal quercetin and investigate its distribution in vivo and antitumor efficacy in vivo and in vitro. EXPERIMENTAL DESIGN Quercetin was encapsulate...
UNLABELLED BACKGROUND Liposomal formulations of anthracyclines appear to have favorable toxicity profile when compared with conventional anthracyclines in elderly, high risk cardiac patients and patients with prior use of anthracyclines. Randomized controlled trials have evaluated the efficacy and safety profile of liposomal formulations with conventional anthracyclines. Our aim is to evalua...
large unilamellar liposomes and multilamellar vesicles consisting of dmpc interacted with cationic phosphorus-containing dendrimers cpds g3 and g4. dsc and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. calorimetric studies indicate that the enthalpy of the transition of the lipids tha...
abstractgene therapy is a therapeutic approach to deliver genetic material into cells to alter their function in entire organism. one promising form of gene delivery system (dds) is liposomes. the success of liposome-mediated gene delivery is a multifactorial issue and well-designed liposomal systems might lead to optimized gene transfection particularly in vivo. liposomal gene delivery systems...
Encapsulating cytostatics into lipid vesicles, i.e. liposomes, improves tumour drug accumulation and reduce adverse effects. Liposomal doxorubicin (DXR) has been used in the treatment of a variety of cancers and may also be suitable for combining with other treatment modalities. By modulating liposomal membranes, liposomes can be made ultrasound (US) sensitive releasing encapsulated drug in tum...
Liposomal magnetofection is a simple, highly efficient technology for cell transfection, demonstrating better outcome than a number of other common gene delivery methods. However, aggregate complexes distribution over the cell surface is non-uniform due to the gradient of the permanent magnetic field. The aim of this study was to estimate the efficiency of liposomal magnetofection for prostate ...
Murine fibrosarcoma tumors arising from subcutaneous inoculation of FSa-N cells exhibit 4-fold higher tumor-associated macrophage (TAM) levels than those from the FSa-R line. These solid tumors were used to assess the role of TAMs in the accumulation of liposomal anticancer drugs. Two liposomal formulations of doxorubicin were investigated: a conventional formulation composed of distearoylphosp...
BACKGROUND Current research suggests that administration of vasopressin to patients with uncontrolled hemorrhagic shock (UHS) can avoid the detrimental effects associated with aggressive fluid resuscitation. However, vasopressin has a short half-life of 10~35 minutes in in vivo use and precludes its use in the pre-hospital setting. To increase the half-life of vasopressin, we proposed to synthe...
The toxicity and antitumor activity of liposomal vincristine prepara tions have been examined. Vincristine was encapsulated inside egg phosphatidylcholine (EPC)/cholesterol (55/45, mol/mol) and distearoylphosphatidylcholine (DSPC)/cholesterol (55/45, mol/mol) vesicles utilizing transmembrane pH gradient (inside acidic) drug uptake processes. Trap ping efficiencies approaching 100% were achieved...
