Inflammation contributes to the process of ventricular remodeling after acute myocardial injury. To investigate the role of macrophages in the chronic process of cardiac remodeling, they were selectively depleted by intravenous administration of liposomal clodronate in heart failure-prone hypertensive Ren-2 rats from the age of 7 until 13 weeks. Plain liposomes were used for comparison. Liposom...

Liposomal bupivacaine is a prolonged-release local anaesthetic, the neurotoxicity of which has not yet been determined. We used quantitative histomorphometric and immunohistochemical analyses to evaluate the neurotoxic effect of liposomal bupivacaine after perineural and intraneural (extrafascicular) injection of the sciatic nerve in pigs. In this double-blind prospective randomised trial, 4 ml...

Liposomes entrapping gadolinium-DTPA (Gd-DTPA) were synthesized from 60 mole percent egg phosphatidylcholine (EPC) and 40 mole percent cholesterol or EPC alone entrapping Gd-DTPA in diameters of 100 and 200 nm. Rats bearing Morris hepatoma in their flanks were imaged by MR pre- and post-contrast with free Gd-DTPA and liposomal Gd-DTPA for up to four hours after IV contrast. Comparison of images...

We developed a liposome-intercalated preparation of amphotericin B by using small, unilamellar vesicles 0.06 to 0.1 micron in diameter. In contrast to previously described liposomal preparations of amphotericin B, these vesicles have the advantage that they are small enough to be filter sterilized. We compared the efficacy of liposomal amphotericin B with that of the commercial drug given as an...

BACKGROUND Historically, children have been undertreated for their pain, and they continue to undergo painful cutaneous procedures without analgesics. A new topical anesthetic, liposomal lidocaine 4% cream (Maxilene, RGR Pharma, Windsor, Ont.), has become available. It has pharmacologic properties that are superior to other topical anesthetics, including an onset of action of only 30 minutes. W...

BACKGROUND Systemic antifungal medications can be lifesaving but can also have important toxicities. With a number of new antifungal drugs being introduced, there is a compelling need to define the toxicities associated with existing therapies. METHODS We identified cases of hepatotoxicity among patients who underwent bone marrow transplantation and selected matched control subjects from the ...

BACKGROUND Folate receptor (FR) is selectively amplified among human tumors, including in 70% of myeloid leukemias. FR-targeted liposomal delivery is an attractive strategy for enhancing the therapeutic efficacy of anticancer agents against FR(+) tumors. In this study, FR-targeted liposomal daunorubicin was evaluated in an FR+ L1210JF murine ascites tumor model for therapeutic efficacy in vivo....

We report on a 37-year-old male HIV-positive patient with generalized cutaneous leishmaniasis undiagnosed for several years. Upon presentation, visceral leishmaniasis was diagnosed in addition to cutaneous manifestation of the disease. Over a period of three years, several different treatment regimens including liposomal amphotericin B, liposomal amphotericin B with miltefosine, liposomal ampho...

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...
