Abstract
Fungal infections represent a challenging threat to the human health. Microsporum gypseum and Trichophyton rubrum are pathogenic fungi causing various topical mycoses in humans. The globally emerging issue of resistance to fungi demands the development of novel therapeutic strategies. In this context, the application of nanoliposomes as vehicles for carrying active therapeutic agents can be a suitable alternative. In this study, rhinacanthin-C was isolated from Rhinacanthus naustus and encapsulated in nano-liposomal formulations, which were prepared by the modified ethanol injection method. The two best formulations composed of soybean phosphatidylcholine (SPC), cholesterol (CHL), and tween 80 (T80) in a molar ratio of 1:1:0 (F1) and 1:1:0.5 (F2) were proceeded for experimentation. The physical characteristics and antifungal activities were performed and compared with solutions of rhinacanthin-C. The rhinacanthin-C encapsulating efficiencies in F1 and F2 were 94.69 ± 1.20% and 84.94 ± 1.32%, respectively. The particle sizes were found to be about 221.4 ± 13.76 nm (F1) and 115.8 ± 23.33 nm (F2), and zeta potential values of -38.16 mV (F1) and -40.98 mV (F2). Similarly, the stability studies of rhinacanthin-C in liposomes demonstrated that rhinacanthin-C in both formulations was more stable in mediums with pH of 4.0 and 6.6 than pure rhinacanthin-C when stored at the same conditions. Rhinacanthin-C in F1 was slightly more stable than F2 when stored in mediums with a pH of 10.0 after three months of storage. However, rhinacanthin-C in both formulations was less stable than pure rhinacanthin-C in a basic medium of pH 10.0. The antifungal potential was evaluated against M. gypsum and T. rubrum. The findings revealed a comparatively higher zone of inhibition for F1. In the MIC study, SPC: CHL: T80 showed higher inhibition against M. gypseum and a slightly higher inhibition against T. rubrum compared to free rhinacanthin-C solution. Moreover, rhinacanthin-C showed significant interaction against 14α-demethylase in in silico study. Overall, this study demonstrates that nanoliposomes containing rhinacanthin-C can improve the stability and antifungal potential of rhinacanthin-C with sustained and prolonged duration of action and could be a promising vehicle for delivery of active ingredients for targeting various fungal infections.

Exploring the therapeutic potential of sodium deoxycholate tailored deformable-emulsomes of etodolac for effective management of arthritis. Sci Rep 2023; 13:21681. [PMID: 38066008 PMCID: PMC10709335 DOI: 10.1038/s41598-023-46119-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 10/27/2023] [Indexed: 12/18/2023] Open
Abstract
The current piece of research intends to evaluate the potential of combining etodolac with deformable-emulsomes, a flexible vesicular system, as a promising strategy for the topical therapy of arthritis. The developed carrier system featured nanometric dimensions (102 nm), an improved zeta potential (- 5.05 mV), sustained drug release (31.33%), and enhanced drug deposition (33.13%) of DE-gel vis-à-vis conventional system (10.34% and 14.71%). The amount of permeation of the developed nano formulation across skin layers was demonstrated through CLSM and dermatokinetics studies. The safety profile of deformable-emulsomes has been investigated through in vitro HaCaT cell culture studies and skin compliance studies. The efficacy of the DE-gel formulation was sevenfold higher in case of Xylene induced ear edema model and 2.2-folds in CFA induced arthritis model than that of group treated with conventional gel (p < 0.01). The main technological rationale lies in the use of phospholipid and sodium deoxycholate-based nanoscale flexible lipoidal vesicles, which effectively encapsulate drug molecules within their interiors. This encapsulation enhances the molecular interactions and facilitates the transportation of the drug molecule effectively to the target-site. Hence, these findings offer robust scientific evidence to support additional investigation into the potential utility of flexible vesicular systems as a promising drug delivery alternative for molecules of this nature.

Rapid Production of Nanoscale Liposomes Using a 3D-Printed Reactor-In-A-Centrifuge: Formulation, Characterisation, and Super-Resolution Imaging. MICROMACHINES 2023; 14:1763. [PMID: 37763926 PMCID: PMC10535575 DOI: 10.3390/mi14091763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 08/29/2023] [Accepted: 09/04/2023] [Indexed: 09/29/2023]
Abstract
Nanoscale liposomes have been extensively researched and employed clinically for the delivery of biologically active compounds, including chemotherapy drugs and vaccines, offering improved pharmacokinetic behaviour and therapeutic outcomes. Traditional laboratory-scale production methods often suffer from limited control over liposome properties (e.g., size and lamellarity) and rely on laborious multistep procedures, which may limit pre-clinical research developments and innovation in this area. The widespread adoption of alternative, more controllable microfluidic-based methods is often hindered by complexities and costs associated with device manufacturing and operation, as well as the short device lifetime and the relatively low liposome production rates in some cases. In this study, we demonstrated the production of liposomes comprising therapeutically relevant lipid formulations, using a cost-effective 3D-printed reactor-in-a-centrifuge (RIAC) device. By adjusting formulation- and production-related parameters, including the concentration of polyethylene glycol (PEG), temperature, centrifugation time and speed, and lipid concentration, the mean size of the produced liposomes could be tuned in the range of 140 to 200 nm. By combining selected experimental parameters, the method was capable of producing liposomes with a therapeutically relevant mean size of ~174 nm with narrow size distribution (polydispersity index, PDI ~0.1) at a production rate of >8 mg/min. The flow-through method proposed in this study has potential to become an effective and versatile laboratory-scale approach to simplify the synthesis of therapeutic liposomal formulations.

Abstract
In recent years, methicillin-resistant Staphylococcus aureus (MRSA) bacteria have seriously threatened the health and safety of the world’s population. This challenge demands the development of alternative therapies based on plant origin. This molecular docking study ascertained the orientation and intermolecular interactions of isoeugenol within penicillin-binding protein 2a. In this present work, isoeugenol as an anti-MRSA therapy was selected by encapsulating it into a liposomal carrier system. After encapsulation into the liposomal carrier, it was evaluated for encapsulation efficiency (%), particle size, zeta potential, and morphology. The percentage entrapment efficiency (% EE) was observed to be 57.8 ± 2.89% with a particle size of 143.31 ± 7.165 nm, a zeta potential of (−)25 mV, and morphology was found to be spherical and smooth. After this evaluation, it was incorporated into a 0.5% Carbopol gel for a smooth and uniform distribution on the skin. Notably, the isoeugenol-liposomal gel was smooth on the surface with a pH of 6.4, suitable viscosity, and spreadability. Interestingly, the developed isoeugenol-liposomal gel was safe for human use, with more than 80% cell viability. The in vitro drug release study shows promising results with 75.95 ± 3.79% of drug release after 24 h. The minimum inhibitory concentration (MIC) was 8.236 µg/mL. Based on this, it can be concluded that encapsulating isoeugenol into the liposomal gel is a potential carrier for MRSA treatment.

Acta Biomater 2022; 145:372-389.

Abstract
Diabetic chronic wounds are difficult to heal because of the presence of excessive inflammation and high overexpression of matrix metalloproteinase-9 (MMP-9), which greatly affects the quality of life of patients with diabetes and increases the risk of death. Thus, the regulation of excessive inflammation and inhibition of MMP-9 overexpression are effective strategies to improve diabetic wound healing. The present study is the first to demonstrate that ion products of 45S5 Bioglass® (BG) can work with small interfering RNA of MMP9 (MMP9-siRNA) to reduce MMP-9 expression in tissue-forming cells and enhance the synthesis of extracellular matrix proteins (ECMs). Specifically, the BG ionic products can stimulate macrophages to convert to M2 phenotype, thereby creating a proregenerative inflammation microenvironment to indirectly suppress the expression of MMP-9 in tissue-forming cells. Chitosan nanoparticles encapsulating MMP9-siRNA (MMP9-siNP) can directly lower MMP-9 expression in tissue-forming cells. In addition, BG ionic products can promote the vascularization of endothelial cells and ECM protein synthesis by fibroblasts. Thus, injectable BG/sodium alginate (BG/SA) hydrogels loaded with MMP9-siNP can significantly accelerate the healing process of full-thickness excision wounds of diabetic rats by decreasing MMP-9 expression, improving collagen synthesis, and enhancing angiogenesis in the wounds, thereby demonstrating their great application potential in treating diabetic chronic wounds. STATEMENT OF SIGNIFICANCE: Excessive inflammation and high overexpression of MMP-9 have been considered as factors that severely hinder the healing process of diabetic chronic wounds. Effective strategies are required for the regulation of excessive inflammation and inhibition of MMP-9 overexpression to enhance diabetic wound healing. In the present work, an injectable bioglass/sodium alginate (BG/SA) hydrogel loaded with MMP9-siNP was developed; this hydrogel significantly accelerated the healing process of full-thickness excision wounds of diabetic rats by decreasing MMP-9 expression, improving collagen accumulation, and enhancing angiogenesis in the wounds. Thus, the BG/SA hydrogel loaded with MMP9-siNP has great potential for use in healing of diabetic chronic wounds.

Abstract
Andrographispaniculata (Burm.f.) Nees has been used as a traditional medicine in Asian countries, especially China, India, Vietnam, Malaysia, and Indonesia. This herbaceous plant extract contains active compounds with multiple biological activities against various diseases, including the flu, colds, fever, diabetes, hypertension, and cancer. Several isolated compounds from A. paniculata, such as andrographolide and its analogs, have attracted much interest for their potential treatment against several virus infections, including SARS-CoV-2. The mechanisms of action in inhibiting viral infections can be categorized into several types, including regulating the viral entry stage, gene replication, and the formation of mature functional proteins. The efficacy of andrographolide as an antiviral candidate was further investigated since the phytoconstituents of A. paniculata exhibit various physicochemical characteristics, including low solubility and low bioavailability. A discussion on the delivery systems of these active compounds could accelerate their development for commercial applications as antiviral drugs. This study critically reviewed the current antiviral development based on andrographolide and its derivative compounds, especially on their mechanism of action as antiviral drugs and drug delivery systems.

Abstract
The current study utilized an artificial neural network (ANN) to generate computational models to achieve process optimization for a previously developed continuous liposome manufacturing system. The liposome formation was based on a continuous manufacturing system with a co-axial turbulent jet in a co-flow technology. The ethanol phase with lipids and aqueous phase resulted in liposomes of homogeneous sizes. The input features of the ANN included critical material attributes (CMAs) (e.g., hydrocarbon tail length, cholesterol percent, and buffer type) and critical process parameters (CPPs) (e.g., solvent temperature and flow rate), while the ANN outputs included critical quality attributes (CQAs) of liposomes (i.e., particle size and polydispersity index (PDI)). Two common ANN architectures, multiple-input-multiple-output (MIMO) models and multiple-input-single-output (MISO) models, were evaluated in this study, where the MISO outperformed MIMO with improved accuracy. Molecular descriptors, obtained from PaDEL-Descriptor software, were used to capture the physicochemical properties of the lipids and used in training of the ANN. The combination of CMAs, CPPs, and molecular descriptors as inputs to the MISO ANN model reduced the training and testing mean relative error. Additionally, a graphic user interface (GUI) was successfully developed to assist the end-user in performing interactive simulated risk analysis and visualizing model predictions.

Abstract
Liposomes play a significant role in encapsulation of various bioactive compounds (BACs), including functional food ingredients to improve the stability of core. This technology can be used for promoting an effective application in functional food and nutraceuticals. Incorporation of traditional and emerging methods for the developments of liposome for loading BACs resulted in viable and stable liposome formulations for industrial applications. Thus, the advance technologies such as supercritical fluidic methods, microfluidization, ultrasonication with traditional methods are revisited. Liposomes loaded with plant and animal BACs have been introduced for functional food and nutraceutical applications. In general, application of liposome systems improves stability, delivery, and bioavailability of BACs in functional food systems and nutraceuticals. This review covers the current techniques and methodologies developed and practiced in liposomal preparation and application in functional foods.

Abstract
The present study demonstrates the extraction and identification of phospholipids (PLs) from peanut seed for formulation of liposomes for pH and thermo-sensitive delivery and release of folic acid (FA), levodopa (DOPA) and, camptothecin (CPT). The TLC, FTIR and GC-MS based characterization of extracted peanut PLs showed phosphatidylethanolamine, cardiolipin and phosphatidic acid as major PLs and palmitic acid and oleic acid as major fatty acids. Liposomes (LSMs) of size 1-2 μm formulated by optimized thin-film hydration method were found to entrap FA, DOPA and CPT with 58, 61.4 and 52.12% efficiency, respectively with good stability. The effect of external stimuli like pH and temperature on the release pattern of FA, DOPA and CPT indicated that FA was optimally released at pH 10 and 57 °C, DOPA at pH 2 and 37 °C, while CPT was best released at pH 6 and 47 °C. When tested for the in vitro activity, DOPA released by DOPA@LSMs showed lower toxicity to 3T3 than to SH-SY5Y cells. Similarly, CPT released by CPT@LSMs showed remarkable anticancer activity against MCF-7 cells with an IC50 value of 17.99 μg/mL. Thus peanut PLs can be efficiently used for liposomal formulations for pH and thermo-sensitive release of drugs.

Abstract
Biodegradable films reinforced with bio-nanomaterials are a solution for developing active packaging systems, shelf-life extension and protection of environment against conventional packaging. This study aimed to characterize the biocompatible chitosan (CS) films formulated with nano-liposomal garlic essential oil (NLGEO) and assess the physicho-mechanical, morphology properties and also microbial and chemical changes in chicken fillets during storage time at 4 °C. NLGEO was obtained by thin-layer hydration-sonication method using glycerol and tween 80 as plasticizer and emulsifier, respectively. Different levels (0, 0.5, 1 and 2%) of NLGEO with average size of ~101 nm were added into the chitosan matrix and films fabricated by casting method. The average size, polydispersity index and zeta potential were ~101 nm, 0.127 and -7.23, respectively. Control samples showed higher values for pH, total volatile nitrogen (TVN), peroxide value (PV), thiobarbituric acid-reactive substances (TBARS), and microbial count including total viable count (TVC), coliforms, Staphylococcus aureus and psychrotroph bacteria than treated samples. The films with higher NLGEO content represented stronger inhibitory effects. The incorporation of NLGEO improved the mechanical properties and water resistance of active films. Microstructure analysis also showed a nearly smooth surface morphology and homogenous structure with a good dispersion for NLGEO films. Significant synergistic effects in chemical and bacterial preservation of chicken fillet samples were observed by NLGEO films. The optimal mechanical and barrier properties of chitosan-NLGEO films introduced it a potential active packaging to extend the shelf life of chicken fillet.

Abstract
Methotrexate (MTX) is a common drug used to treat rheumatoid arthritis. Due to the excessive side effects, encapsulation of MTX in liposomes is considered an effective delivery system, reducing drug toxicity, while maintaining its efficacy. The ethanol injection method is an interesting technique for liposome production, due to its simplicity, fast implementation, and reproducibility. However, this method occasionally requires the extrusion process, to obtain suitable size distribution, and achieve a low level of MTX encapsulation. Here, we develop a novel pre-concentration method, based on the principles of the ethanol injection, using an initial aqueous volume of 20% and 1:1 ratio of organic:aqueous phase (v/v). The liposomes obtained present small values of size and polydispersity index, without the extrusion process, and a higher MTX encapsulation (efficiency higher than 30%), suitable characteristics for in vivo application. The great potential of MTX to interact at the surface of the lipid bilayer was shown by nuclear magnetic resonance (NMR) studies, revealing mutual interactions between the drug and the main phospholipid via hydrogen bonding. In vivo experiments reveal that liposomes encapsulating MTX significantly increase the biological benefit in arthritic mice. This approach shows a significant advance in MTX therapeutic applications.

Abstract
Current chemotherapy for lung cancer achieved limited efficacy due to poor tumor targeting and tissue penetration. Another obstacle in the therapy is activated nuclear factor-κB (NF-κB) in tumor cells, which plays a crucial role in promotion of antiapoptosis and drug resistance. In this study, we utilized a multifunctional liposome loaded with irinotecan and surface modified with a cell-permeable NF-κB inhibitor (CB5005), for treatment of non-small-cell lung carcinoma. CB5005 downregulated the level of NF-κB-related protein in the nuclei of A549 cells, and increased cellular uptake of the modified liposomes. In vivo antitumor activity in mice bearing A549 xenografts revealed that modification with CB5005 significantly improved the tumor inhibition rate of irinotecan. Immunohistochemical assays showed that the tumors treated with CB5005-modified liposomes possessed the most apoptotic cells and the lowest level of p50 in the cell nuclei. These results strongly suggest that antitumor efficacy of the irinotecan liposomes can be enhanced by tumor-penetrating and NF-κB-inhibiting functions of CB5005. Consequently, CB5005-modified liposomes provide a possible synergistic therapy for lung cancer, and would also be appropriate for other types of tumors associated with elevated NF-κB activity.

Abstract
Essential oils (EOs) are widely used in various industrial sectors but can present several instability problems when exposed to environmental factors. Encapsulation technologies are effective solutions to improve EOs properties and stability. Currently, the encapsulation in lipid nanoparticles has received significant attention, due to the several recognized advantages over conventional systems. The study aimed to investigate the influence of the lipid matrix composition and spray-drying process on the physicochemical properties of the lipid-based nanoparticles loaded with Lippia sidoides EO and their retention efficiency for the oil. The obtained spray-dried products were characterized by determination of flow properties (Carr Index: from 25.0% to 47.93%, and Hausner ratio: from 1.25 to 1.38), moisture (from 3.78% to 5.20%), water activity (<0.5), and powder morphology. Zeta potential, mean particle size and polydispersity index, of the redispersed dried product, fell between −25.9 mV and −30.9 mV, 525.3 nm and 1143 nm, and 0.425 and 0.652, respectively; showing slight differences with the results obtained prior to spray-drying (from −16.4 mV to −31.6 mV; 147 nm to 1531 nm; and 0.459 to 0.729). Thymol retention in the dried products was significantly lower than the values determined for the liquid formulations and was affected by the drying of nanoparticles.

Abstract
ABSTRACT The aim of this study was to load liposomes with Barije (Ferula gummosa) essential oil (EO) and to evaluate their physical and antibacterial properties. Liposomes were produced with specific ratios of lecithin/cholesterol by thin-film hydration and sonication. The chemical composition of the EO was analyzed by gas chromatography and mass spectroscopy. The physical properties of the liposomes (particle size, polydispersity index, zeta potential, and encapsulation efficiency) were evaluated. The antimicrobial effects of these liposomes against Escherichia coli O157:H7 were determined based on the MIC and disk diffusion results. The effect of subinhibitory concentrations (sub-MICs) of EO against the growth of the bacterium over 24 h was evaluated before and after encapsulation. The major components of EO were β-pinene (60.84%) and α-pinene (9.14%). The mean liposome radius of EO-loaded liposomes was 74.27 to 99.93 nm, which was significantly different from that of the empty liposomes (138.76 nm) (P < 0.05). Addition of cholesterol to the lecithin bilayer increased the particle size and reduced the encapsulation efficiency (P < 0.05). The electrostatic stability of the empty liposomes was improved by adding cholesterol, but when the EO was replaced in the liposomes, there was no significant change in electrostatic stability of liposomes with cholesterol (P < 0.05). MICs were 14.5 μg/mL for the EO-loaded nanoliposomes containing 30 mg of lecithin and 30 mg of cholesterol and 10 μg/mL for nonencapsulated EO. This trend was confirmed by measuring the inhibition zone diameter. Sub-MICs of liposomal EO (containing 60 mg of lecithin) decreased bacterial levels to a greater degree than did free EO, especially at 50 and 75% of the MIC. HIGHLIGHTS

Abstract
The paper deals with the preparation and characterisation of hydroalcoholic polyphenolic extract from Sambucus ebulus (SE) leaves that was further loaded into three-types of lipid vesicles: liposomes, transfersomes, and ethosomes, to improve its bioavailability and achieve an optimum pharmacological effect. For Sambucus ebulus L.-loaded lipid vesicles, the entrapment efficiency, particle size, polydispersity index and stability were determined. All prepared lipid vesicles showed a good entrapment efficiency, in the range of 75–85%, nanometric size, low polydispersity indexes, and good stability over three months at 4 °C. The in vitro polyphenols released from lipid vehicles demonstrated slower kinetics when compared to the free extract dissolution in phosphate buffer solution at pH 7.4. Either free SE extract or SE extract loaded into lipid vesicles demonstrated a cytoprotective effect, even at low concentration, 5 ug/mL, against hydrogen peroxide-induced toxicity on L-929 mouse fibroblasts’ cell lines. However, the cytoprotective effect depended on the time of the cells pre-treatment with SE extract before exposure to a hydrogen peroxide solution of 50 mM concentration, requiring at least 12 h of pre-treatment with polyphenols with radical scavenging capacity.

Abstract
A well-known strategy for managing pest resistance is application of mixture of pesticides. Conventionally formulated pesticides have several environmental incompatibilities. The use of biocompatible and biodegradable nanocarriers in formulating pesticides could improve environmental protection. In this study, a mixture of imidacloprid and lambda-cyhalothrin was co-encapsulated for the first time using liposomes as nanocarrier to simultaneously deliver these insecticides. Ethanol injection was used to produce self-assembled liposomes. The formed nanoliposomes were coated with different concentrations of chitosan. Nanoparticles were characterized by dynamic light scattering (DLS), scanning electron microscope (SEM) and FT-IR spectroscopy. The encapsulation efficiencies of lambda-cyhalothrin and imidacloprid were about 93% and 51%, respectively. The insecticide carrying liposomes had a size and surface charge of 57 nm and +0.6 mV, respectively. The size and surface charge of the particles produced were increased to 69 nm and +31 mV after being coated with chitosan (0.1%, W/V). In this study, residual activity of technical grade imidacloprid, lambda-cyhalothrin and their mixture and the effect of adjuvants used in commercial and nano formulations of these insecticides on Myzus persicae Sulzer was investigated. The insecticidal effects and duration of residual activity of nano-formulations was correlated with concentration of chitosan in final formulation. In accordance with the life cycle of M. persicae, using the mixture of imidacloprid and lambda-cyhalothrin improves the residual effect over their use alone. The use of lipid nanocarriers makes the improvement even further and can be a better alternative to conventional combination of these insecticides due to their more environmental friendliness.

[PMID: 31151624 DOI: 10.1016/j.foodchem.2019.05.015] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 04/22/2019] [Accepted: 05/02/2019] [Indexed: 01/06/2023]
Abstract
In this study, the efficiency and practical utilization feasibility of niosomal and liposomal nanovesicles loading Isoleucine-Proline-Proline (IPP) as suitable ingredients of functional beverages were evaluated. Vesicles were tailored by different preparation methods using phospholipid and non-ionic surfactants. The optimization process was performed by central composite design approach. The results of Fourier transform infrared spectroscopy demonstrated the compatibility of IPP with the vesicles. The phospholipidic nanovesicles, produced by modified ethanol injection-microchannel technique, were smaller with lower polydispersity index than non-ionic surfactant vesicles developed by the method of thin film hydration and probe sonication. However, niosomal model functional beverage exhibited more proper palatability, biological activity and physicochemical properties during long-term storage than liposomal one. Moreover, niosomes exhibited more sustained release behaviour in simulated blood fluid than liposomes. These findings are of great importance for design and development of the functional foods containing IPP.

Abstract
A series of 1,2-dihydroquinoline derivatives were synthesized and evaluated for cytotoxicity in HeLa, Hep G2 and 6HEK-293T cell lines. EEDQ2 was identified as a promising anti-cancer agent with low IC50 in HeLa (18.55μg/ml) and Hep G2 (14.53μg/ml) cells. For improving the antitumor activity and tumor selectivity of EEDQ2, we prepared transferrin (Tf)-modified liposomes (LPs) to deliver EEDQ2. When HeLa and Hep G2 cells were treated with LP-delivered EEDQ2, the ROS level was significantly enhanced, and mitochondrial membrane potential was reversed. Tf-LPs improved cell uptake of EEDQ2 by about 3.7 times compared with non-targeted LPs. These data suggest that Tf-LPs delivering EEDQ2 is a promising strategy to treat cancer.

Abstract
Liposomes are spherical-enclosed membrane vesicles mainly constructed with lipids. Lipid nanoparticles are loaded with therapeutics and may not contain an enclosed bilayer. The majority of those clinically approved have diameters of 50-300 nm. The growing interest in nanomedicine has fueled lipid-drug and lipid-protein studies, which provide a foundation for developing lipid particles that improve drug potency and reduce off-target effects. Integrating advances in lipid membrane research has enabled therapeutic development. At present, about 600 clinical trials involve lipid particle drug delivery systems. Greater understanding of pharmacokinetics, biodistribution, and disposition of lipid-drug particles facilitated particle surface hydration technology (with polyethylene glycol) to reduce rapid clearance and provide sufficient blood circulation time for drug to reach target tissues and cells. Surface hydration enabled the liposome-encapsulated cancer drug doxorubicin (Doxil) to gain clinical approval in 1995. Fifteen lipidic therapeutics are now clinically approved. Although much research involves attaching lipid particles to ligands selective for occult cells and tissues, preparation procedures are often complex and pose scale-up challenges. With emerging knowledge in drug target and lipid-drug distribution in the body, a systems approach that integrates knowledge to design and scale lipid-drug particles may further advance translation of these systems to improve therapeutic safety and efficacy.

Abstract
Many cationic lipids have been developed for lipid-based nanoparticles (LNPs) for delivery of siRNA and microRNA (miRNA). However, less attention has been paid to "helper lipids". Here, we investigated several "helper lipids" and examined their effects on the physicochemical properties such as particle size and zeta potential, as well as cellular uptake and transfection efficiency. We found that inclusion of oleic acid (OA), an unsaturated fatty acid, into the LNP formulation significantly enhanced the delivery efficacy for siRNA and miRNA. For proof-of-concept, miR-122, a liver-specific microRNA associated with many liver diseases, was used as a model agent to demonstrate the hepatic delivery efficacy both in tumor cells and in animals. Compared to Lipofectamine 2000, a commercial transfection agent, LNPs containing OA delivered microRNA-122 in a more efficient manner with a 1.8-fold increase in mature miR-122 expression and a 20% decrease in Bcl-w, a target of microRNA-122. In comparison with Invivofectamine, a commercial transfection agent specifically designed for hepatic delivery, LNPs containing OA showed comparable liver accumulation and in vivo delivery efficiency. These findings demonstrated the importance of "helper lipid" components of the LNP formulation on the cellular uptake and transfection activity of siRNA and miRNA. LNPs containing OA is a promising nanocarrier system for the delivery of RNA-based therapeutics in liver diseases.

Abstract
In the recent years there has been an increased interest toward the biological activities of essential oils. However, essential oils are unstable and susceptible to degradation in the presence of oxygen, light and temperature. So, attempts have been made to preserve them through encapsulation in various colloidal systems such as microcapsules, microspheres, nanoemulsions and liposomes. This review focuses specifically on encapsulation of essential oils into liposomes. First, we present the techniques used to prepare liposomes encapsulating essential oils. The effects of essential oils and other factors on liposome characteristics such as size, encapsulation efficiency and thermal behavior of lipid bilayers are then discussed. The composition of lipid vesicles membrane, especially the type of phospholipids, cholesterol content, the molar ratio of essential oils to lipids, the preparation method and the kind of essential oil may affect the liposome size and the encapsulation efficiency. Several essential oils can decrease the size of liposomes, homogenize the liposomal dispersions, increase the fluidity and reduce the oxidation of the lipid bilayer. Moreover, liposomes can protect the fluidity of essential oils and are stable at 4-5 °C for 6 months at least. The applications of liposomes incorporating essential oils are also summarized in this review. Liposomes encapsulating essential oils are promising agents that can be used to increase the anti-microbial activity of the essential oils, to study the effect of essential oils on cell membranes, and to provide alternative therapeutic agents to treat several diseases.

Abstract
Liposomes incorporating polyethylene glycol (PEG)-conjugated lipids (PEGylated liposomes) have attracted attention as drug delivery carriers because they show good in vivo stability. The lipid component of PEGylated liposomal formulations needs to be quantified for quality control. In this study, a simple reversed-phase high-performance liquid chromatography (HPLC) method with an evaporative light-scattering detector (ELSD) was established for simultaneous determination of hydrogenated soy phosphatidylcholine, cholesterol, PEG-conjugated lipid, and hydrolysis products of phospholipid in PEGylated liposomal formulations. These lipids were separated using a C18 column with a gradient mobile phase consisting of ammonium acetate buffer and ammonium acetate in methanol at a flow rate of 1.0 ml/min. This method provided sufficient repeatability, linearity, and recovery rate for all lipids. However, the linearity and recovery rates of cholesterol achieved using a ultraviolet (UV) detector were better than those achieved using an ELSD. This validated method can be applied to assess the composition change during the preparation process of liposomes and to quantify lipid components and hydrolysis products contained in a commercially available liposomal formulation DOXIL®. Taken together, this reversed-phase HPLC-UV/ELSD method may be useful for the rapid or routine analysis of liposomal lipid components in process development and quality control.

Abstract
We have investigated the effects of two bile salts, chenodeoxycholate (CDC) and ursodeoxycholate (UDC), and a widely used detergent, Triton X-100 (T(X-100)), on normal and poly(ethylene glycol)-modified liposomes (PEGylated liposomes). We tested various lipid compositions, including hydrogenated soybean phosphatidylcholine/cholesterol/PEG-conjugated lipid (HSPC/PEG-lipid). Alterations in permeability were determined by the rate of drug release from the liposomes and solubilization was assessed by measuring the particle size of liposomes. In addition, we attempted to observe interactions between the detergents and lipid bilayers by using surface plasmon resonance (SPR). CDC induced drug release from liposomes in a dose-dependent manner, and the PEGylated liposomes tended to be susceptible to CDC. While UDC did not strongly induce drug release from liposomes, UDC exhibited a similar tendency with CDC. In case of T(X-100), there were significant differences in the percentage of released drug between normal and PEGylated liposomes, and the percentage of T(X-100)-induced drug release further increased with an increased ratio of PEG-lipid. SPR analysis revealed that the lipid bilayer including PEG-lipid was selectively solubilized by T(X-100), correlating with the drug release data. These results suggest that the effect of detergents on the lipid bilayer of liposomes depends on both the kind of detergent and the lipid composition, including the presence or absence of PEG-lipid. Moreover, the effects of T(X-100) on the lipid bilayers of the PEGylated liposomes significantly differed from those on the lipid bilayers of the normal liposomes.

Abstract
A modified and derived ethanol injection (MDEI) process was developed to produce liposomes. The aim of the present study was to more efficiently control the vesicle diameter than with the conventional ethanol injection method. A hot ethanolic solution of lipids (60°C) was injected into a hot aqueous buffer (70°C). Then, ethanol was removed by rotary evaporation under reduced pressure. The size of the liposomes could be controlled by the ratio of ethanol to hydroalcoholic solution before evaporation. The concentration of lipids, the charge of lipids, and the type of aqueous phase had little effect on the vesicle diameter when the process involved a ratio of 33% (v/v) ethanol. In addition, it was possible to obtain lipid concentrations 10- to 30-fold higher that the conventional ethanol injection method. The encapsulation of a hydrophilic compound was feasible with this MDEI process. The observation by cryogenic transmission electron microscopy revealed that these liposomes were predominantly unilamellar at a ratio as high as 33 or 50% (v/v) ethanol. Thus, the results showed that MDEI is an appropriate alternative for the manufacture of liposomes with respect to the ethanol injection process.

Abstract
Three hundred and fifty 14-day-old chickens were randomly assigned to 7 groups. At the same time of vaccination with Newcastle disease vaccine, the chickens in experimental groups were injected with propolis flavonoids liposome (PFL) at three doses, PF and blank liposome, respectively. The titer of serum antibody, concentrations of immunoglobulins G (IgG) and immunoglobulins M (IgM), activity of lymphocytes proliferation and concentrations of cytokines were measured. The results showed that three doses of PFL could significantly enhance antibody titer, concentrations of IgG, IgM, and promote lymphocyte proliferation, interferon-γ and interleukin-2 secretion, and its high and medium doses possessed the best efficacy. In general evaluation, the efficacy of PFL was the best, with certain of dose- and time-effect relationships. These findings indicated that the immunological activity of PF could be enhanced with liposome encapsulation.

Abstract
The aim of this study was to design and optimize a transdermal liposomes gel formulation for paeonol (PAE). A three-factor, three-level Box-Behnken design was used to derive a second-order polynomial equation to construct three-dimensional (3-D) contour plots for prediction of responses. Independent variables studied were the DC-Chol concentration (X₁), molar ratio of lipid/drug (X₂), and the polymer concentration (X₃), and the levels of each factor were low, medium, and high. The dependent variables studied were the encapsulation efficiency (%EE) of PAE (Y₁), flux of PAE (Y₂), and viscosity of the gels (Y₃). Response surface plots were drawn and statistical validity of the polynomials was established to find the compositions of optimized formulation, which was evaluated using the Franz diffusion cell. The %EE of PAE increased proportionally with the molar ratio of lipid/drug, but decreased with polymer concentration, whereas the flux of PAE increased proportionally with polymer concentration and the DC-Chol concentration. The viscosity of gels increased with the polymer concentration. Gels showed a non-Fickian diffusion release mechanism for PAE, and the in vitro release profiles were fit for Higuchi's order model. The design demonstrated the role of the derived polynomial equation and 3-D contour plots in predicting the values of dependent variables for the preparation and optimization of gel formulation for transdermal drug release.

Abstract
Liposomes, spherical vesicles consisting of one or more phospholipid bilayers, were first described in the mid 60s by Bangham and coworkers. Since then, liposomes have made their way to the market. Today, numerous lab scale but only a few large-scale techniques are available. However, a lot of these methods have serious limitations in terms of entrapment of sensitive molecules due to their exposure to mechanical and/or chemical stress. This paper summarizes exclusively scalable techniques and focuses on strengths, respectively, limitations in respect to industrial applicability. An additional point of view was taken to regulatory requirements concerning liposomal drug formulations based on FDA and EMEA documents.

Abstract
In this article, a hydrophobic (beclomethasone dipropionate; BDP) and a hydrophilic (cytarabine; Ara-C) drugs have been encapsulated in liposomes in order to be administered via the pulmonary route. For this aim, a liposome preparation method, which is easy to scale up, the ethanol injection method, has been selected. The effects of critical process and formulation parameters have been investigated. The drug-loaded liposomes were prepared and characterized in terms of size, zeta potential, encapsulation efficiency, release study, cell uptake, and aerodynamic behavior. Small multilamellar vesicles, with sizes ranging from about 80 to 170 nm, were successfully obtained. Results indicated a significant influence of phospholipid and cholesterol amounts on liposome size and encapsulation efficiency. The higher encapsulation efficiencies were about 100% for the hydrophobic drug (BDP) and about 16% for the hydrophilic one (Ara-C). The in vitro release study showed a prolonged release profile for BDP, in contrast with Ara-C, which was released more rapidly. The cell-uptake test revealed that fluorescent liposomes have been well internalized into the cytoplasm of SW-1573 human lung carcinoma cells, confirming the possibility to use liposomes for lung cell targeting. Nebulized Ara-C and BDP liposomes presented aerodynamic diameters compatible with deep lung deposition. In conclusion, the elaborated liposomes seem to be promising carriers for both Ara-C and BDP pulmonary delivery.

Abstract
Cationic liposomes composed of 3beta-[N-(N'N'-dimethylaminoethane)carbamoyl] cholesterol (DC-Chol) and dioleoylphosphatidylethanolamine (DOPE) (DC-Chol/DOPE liposome, molar ratio, 1:1 or 3:2) prepared by the dry-film method have been often used as non-viral gene delivery vectors. We have shown that a more efficient transfection in medium with serum was achieved using DC-Chol/DOPE liposomes (molar ratio, 1:2) than those (3:2), and preparation method by a modified ethanol injection than the dry-film. The most efficient DC-Chol/DOPE liposome for gene transfer was molar ratio (1:2) and prepared by a modified ethanol injection method. The enhanced transfection is related to an increase in the release of DNA in the cytoplasm by the large lipoplex during incubation in opti-MEM I reduced-serum medium (optiMEM), not to an increased cellular association with the lipoplex. Cationic liposomes rich in DOPE prepared by a modified ethanol injection method will help to improve the efficacy of liposome vector systems for gene delivery.

Abstract
For injectable-sized liposome complexed with DNA (lipoplexes) with high transfection efficiency of genes, we initially prepared small-sized liposomes by addition of biosurfactant. For selectivity of gene expression, the thymidine kinase (MK-tk) gene controlled by midkine was used for herpes simplex virus thymidine kinase (HSV-tk) gene therapy. Liposomes composed of 3([N-(N',N'-dimethylaminoethane)-carbamoyl] cholesterol (DC-Chol), L-dioleoylphosphatidylethanolamine (DOPE), and a biosurfactant, such as beta-sitosterol beta-D-glucoside (Sit-G) for Sit-G-liposomes and mannosylerythrytol lipid A (MEL) for MEL-liposomes, produced about 300-nm-sized lipoplexes. Sit-G- and MEL-liposomes showed higher transfection efficiency of the luciferase marker gene and thymidine kinase activity in the presence of serum in the cells. The treatment with transfection of MK-tk gene by Sit-G-liposome and injection of ganciclovir significantly reduced tumor growth in a solid tumor model, compared with that by Sit-G-liposome alone. This finding suggested that Sit-G-liposome is a potential vector for HSV-tk gene therapy.

Abstract
Small-sized liposomes have several advantages as drug delivery systems, and the ethanol injection method is a suitable technique to obtain the spontaneous formation of liposomes having a small average radius. In this paper, we show that liposomal drug formulations can be prepared in situ, by simply injecting a drug-containing lipid(s) organic solution into an aqueous solution. Several parameters should be optimized in order to obtain a final suitable formulation, and this paper is devoted to such an investigation. Firstly, we study the liposome size distributions determined by dynamic light scattering (DLS), as function of the lipid concentration and composition, as well as the organic and aqueous phases content. This was carried out, firstly, by focusing on POPC (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine) then on the novel L-carnitine derivative PUCE (palmitoyl-(R)-carnitine undecyl ester chloride), showing that it is possible to obtain monomodal size distributions of rather small vesicles. In particular, depending on the conditions, it was possible to achieve a population of liposomes with a mean size of 100 nm, when a 50 mM POPC ethanol solution was injected in pure water; in the case of 50 mM PUCE the mean size was around 30 nm, when injected in saline (0.9% NaCl). The novel anticancer drug Gimatecan, a camptothecin derivative, was used as an example of lipophilic drug loading by the injection method. Conditions could be found, under which the resultant liposome size distributions were not affected by the presence of Gimatecan, in the case of POPC as well as in the case of PUCE. To increase the overall camptothecin concentration in the final liposomal dispersion, the novel technique of "multiple injection method" was used, and up to a final 5 times larger amount of liposomal drug could be reached by maintaining approximately the same size distribution. Once prepared, the physical and chemical stability of the liposome formulations was satisfactory within 24, as judged by DLS analysis and HPLC quantitation of lipids and drug. The Gimatecan-containing liposomes formulations were also tested for in vitro and in vivo activity, against the human nonsmall cell lung carcinoma NCI-H460 and a murine Lewis lung carcinoma 3 LL cell lines. In the in vitro tests, we did not observe any improvement or reduction of the Gimatecan pharmacological effect by the liposomal delivery system. More interestingly, in the in vivo Lewis lung carcinoma model, the intravenously administration of liposomal Gimatecan formulation showed a mild but significant increase of Tumor Volume Inhibition with respect to the oral no-liposomal formulation (92% vs. 86 %, respectively; p < 0.05). Finally, our study showed that the liposomal formulation was able to realize a delivery system of a water-insoluble drug, providing a Gimatecan formulation for intravenous administration with a preserved antitumoral activity.
