Lipid Based Nanoparticles As A Novel Treatment Modality For Hepatocellular Carcinoma: A Comprehensive Review On Targeting And Recent Advances, Khaled Mahmoud, Shady Swidan, Mohamed A. El-Nabarawi, Mahmoud H. Teaima
Lipid Based Nanoparticles As A Novel Treatment Modality For Hepatocellular Carcinoma: A Comprehensive Review On Targeting And Recent Advances, Khaled Mahmoud, Shady Swidan, Mohamed A. El-Nabarawi, Mahmoud H. Teaima

Liver cancer is considered one of the deadliest diseases with one of the highest disease burdens worldwide. Among the different types of liver cancer, hepatocellular carcinoma is considered to be the most common type. Multiple conventional approaches are being used in treating hepatocellular carcinoma. Focusing on drug treatment, regular agents in conventional forms fail to achieve the intended clinical outcomes. In order to improve the treatment outcomes, utilizing nanoparticles—specifically lipid based nanoparticles—are considered to be one of the most promising approaches being set in motion. Multiple forms of lipid based nanoparticles exist including liposomes, solid lipid nanoparticles, nanostructured lipid carriers, …
Exploiting Modulation Of The Blood-Brain And Blood-Tumor Barrier Permeability By Translational Focused Ultrasound For Therapeutic Delivery To Cns Metastases, Tasneem A. Arsiwala
Exploiting Modulation Of The Blood-Brain And Blood-Tumor Barrier Permeability By Translational Focused Ultrasound For Therapeutic Delivery To Cns Metastases, Tasneem A. Arsiwala
Graduate Theses, Dissertations, and Problem Reports
Transcranial low-intensity focused ultrasound is a unique technology to modulate the integrity of tight endothelial junctions and transiently increase BBB/BTB permeability to enhance therapeutic delivery. Despite promising early studies, present literature lacks agreement on key experimental conditions, which restricts our knowledge and the technique's widespread translation. This dissertation first provides a critical review of the current gaps in knowledge regarding the universal use of LiFUS in preclinical and clinical use. We then identify key parameters for translational and predictable opening of the BBB using a 3T MRI coupled with a clinical device. Our investigation highlights that passive permeability of the …
Quantification Of Factors Governing Drug Release Kinetics From Nanoparticles: A Combined Experimental And Mechanistic Modeling Approach, Kyle Daniel Fugit
Quantification Of Factors Governing Drug Release Kinetics From Nanoparticles: A Combined Experimental And Mechanistic Modeling Approach, Kyle Daniel Fugit
Theses and Dissertations--Pharmacy
Advancements in nanoparticle drug delivery of anticancer agents require mathematical models capable of predicting in vivo formulation performance from in vitro characterization studies. Such models must identify and incorporate the physicochemical properties of the therapeutic agent and nanoparticle driving in vivo drug release. This work identifies these factors for two nanoparticle formulations of anticancer agents using an approach which develops mechanistic mathematical models in conjunction with experimental studies.
A non-sink ultrafiltration method was developed to monitor liposomal release kinetics of the anticancer agent topotecan. Mathematical modeling allowed simultaneous determination of drug permeability and interfacial binding to the bilayer from release …
Liposomal Fasudil, A Rho-Kinase Inhibitor, For Prolonged Pulmonary Preferential Vasodilation In Pulmonary Arterial Hypertension, Vivek Gupta, Nilesh Gupta, Imam H. Shaik, Reza Mehvar, Ivan F. Mcmurty, Masahiko Osa, Eva Nozik-Grayck, Fakhrul Ahsan

Current pharmacological interventions for pulmonary arterial hypertension (PAH) require continuous infusions, multiple inhalations, or oral administration of drugs that act on various pathways involved in the pathogenesis of PAH. However, invasive methods of administration, short duration of action, and lack of pulmonary selectivity result in noncompliance and poor patient outcomes. In this study, we tested the hypothesis that encapsulation of an investigational anti-PAH molecule fasudil (HA-1077), a Rho-kinase inhibitor, into liposomal vesicles results in prolonged vasodilation in distal pulmonary arterioles. Liposomes were prepared by hydration and extrusion method and fasudil was loaded by ammonium sulfate-induced transmembrane electrochemical gradient. Liposomes were …
Archaeosomes And Tetraether Lipid Liposome, Hans-Joachim Freisleben
Archaeosomes And Tetraether Lipid Liposome, Hans-Joachim Freisleben
Majalah Ilmu Kefarmasian
Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up the majority of total membrane lipids. Archaeal lipids are able to form stable liposomal structures, both from membrane factions, mainly the polar membrane fraction, i.e. archaeosomes, or from highly purified TEL (tetraether lipid liposomes). Liposomes of the main polar lipid (MPL) from thermoacidophilic archaeon Ihermoplasma acidophilum were thoroughly inevstigated. Archaeosomes and TEL liposomes exhibit extremely low proton permeability and high stability at …
Development And Evaluation Of Paclitaxel-Loaded Liposomal Formulations For Targeted Drug Delivery To Breast Cancer, Vinayagam Kannan
Development And Evaluation Of Paclitaxel-Loaded Liposomal Formulations For Targeted Drug Delivery To Breast Cancer, Vinayagam Kannan
Theses and Dissertations (ETD)
The objective of this work was to develop and evaluate paclitaxel-loaded liposomal formulations for targeted drug delivery to breast cancer. The liposomal formulation was optimized to maximize drug loading and physical stability. Cholesterol and saturated lipid content showed a negative influence on paclitaxel loading. Short-term stability studies showed that optimum drug-lipid ratio is necessary for adequate physical stability. Biodistribution studies in mouse xenografts bearing MDA-MB-231 breast cancer using near infrared fluorescence imaging showed that the accumulation of tumor vasculature targeted long-circulating liposomes (LCL) in the tumor was significantly less than non-targeted LCL at 48 h. The accumulation of these liposomes …
