Abstract
Docetaxel (DTX) is a semi-synthetic analogue of paclitaxel which has attracted extensive attention in the treatment of cancer. However, the current clinically used DTX formulations display low tumor targeting ability, leading to unsatisfactory therapeutic outcomes with adverse effects, which poses significant challenges to the clinical application. In this study, three galactosamine (Gal) and docetaxel conjugates with different linkers were synthesized, namely DTX-(suc-Gal)2, DTX-(DTDPA-Gal)2, and DTX-(DSeDPA-Gal)2. These three conjugates were characterized by 1H NMR, FT-IR and HRMS. The in vitro drug release study shows that DTX-(DTDPA-Gal)2 and DTX-(DSeDPA-Gal)2 exhibit glutathione (GSH)-responsive drug release and DTX-(DSeDPA-Gal)2 displays higher GSH-responsiveness. The in vitro antitumor activity study shows that DTX-(DTDPA-Gal)2 and DTX-(DSeDPA-Gal)2 exhibit enhanced cytotoxicity, cell apoptosis rate and G2/M phase arrest against HepG2 cells as compared to DTX-(suc-Gal)2, DTX-(DSeDPA-Gal)2 displays the highest cytotoxicity, cell apoptosis rate and G2/M phase arrest among these three conjugates. In addition, DTX-(DSeDPA-Gal)2 exhibits higher selectivity to HepG2 cells as compared to free DTX. The DTX-(DSeDPA-Gal)2 developed in this study has been proven to be an effective DTX conjugate for selective killing hepatoma cells.

Abstract
Peptosomes, as a vesicular polypeptide-based system and a versatile carrier for co-delivery of hydrophilic and hydrophobic materials, provide great delivery opportunities due to the intrinsic biocompatibility and biodegradability of the polypeptides backbone. In the current study, a novel poly(L-glutamic acid)-block-polylactic acid di-block copolymer (PGA-PLA) was synthesized in two steps. Firstly, γ-benzyl L-glutamate-N-carboxy anhydride (BLG-NCA) and 3,6-dimethyl-1,4-dioxane-2,5-dione were polymerized using N-hexylamine and benzyl alcohol as initiators to produce poly(γ-benzyl L-glutamate (PBLG) and polylactic acid. Then, PBLG was deprotected to produce PGA. Secondly, PGA was conjugated to the benzyl-PLGA to fabricate PGA-PLA diblock copolymer. The synthesized diblock copolymer was used for the encapsulation of doxorubicin, as hydrophilic anticancer and ultra-small superparamagnetic iron oxide nanoparticles (USPIONs) as hydrophobic contrast agent within aqueous core and bilayer of vesicular peptosome, respectively via double emulsion method. The prepared peptosomes (Pep@USPIONs-DOX) controlled the release of DOX (<15 % of the encapsulated DOX release up to 240 h of incubation at the physiological conditions) while increasing the stability and solubility of the hydrophobic USPIONs. Then, AS1411 DNA aptamer was decorated on the surface of the PGA-PLA peptosomes (Apt-Pep@USPIONs-DOX). The prepared targeted and non-targeted platforms showed spherical morphology with hydrodynamic sizes of 265 ± 52 and 229 ± 44 nm respectively. In vitro cellular cytotoxicity and cellular uptake were studied in nucleolin positive (4T1) and nucleolin negative (CHO) cell lines. Cellular uptake of the targeted formulation was greater than that of non-targeted peptosome, while cellular internalization of these peptosomes was identical in CHO cells. Moreover, targeted peptosomes showed greater toxicity than non-targeted peptosome in 4T1 cell line. The prepared theranostic targeted peptosomes demonstrated improved capability in terms of survival rate, biodistribution, tumor suppression efficiency, and MR imaging in the 4T1 tumor-bearing mice.

Abstract
In this work, glycyrrhetinic acid (GA)-β-cyclodextrin grafted pullulan (GCDPu) was synthesized and used to form nanoparticles for liver-specific drug delivery. GCDPu was characterized by Fourier transform infrared (FT-IR) and proton nuclear magnetic resonance (1H NMR). The self-aggregated nanoparticles (GCDPu NPs) with a spherical dimension of about 200 nm were prepared and analyzed by dynamic light scattering (DLS), zeta potential, and transmission electron microscopy (TEM). Doxorubicin (DOX) was selected as an anti-cancer model drug, and the drug-loaded GCDPu NPs were prepared by the emulsion solvent evaporation method. Moreover, the drug encapsulation efficiency (LE%) and loading content (LC%) were determined. Slow DOX release from DOX/GCDPu NPs was confirmed. GCDPu NPs were cytocompatible with Bel-7404 cells and showed high cellular uptake according to the MTT assay, confocal laser scanning microscope (CLSM) and flow cytometry (FCM) results. Compared with free DOX, DOX/GCDPu NPs have exhibited a longer half-life time (t1/2) and a larger area-under-the-curve (AUC). GCDPu NPs significantly increased DOX contents in the liver and decreased in heart and kidney. Furthermore, DOX/GCDPu NPs exhibited a better anticancer therapeutic effect on tumor-bearing mice. These findings suggest that GCDPu can serve a liver-specific drug delivery system.

Abstract
Curcumin is a well-recognized antioxidant phytoactive isolated from the rhizomes of Curcuma longa. Numerous landmark investigations have proved the antioxidant and hepatoprotective potential of curcumin. The aim of present study was to target curcumin loaded nanocarriers to hepatocytes using asialoglycoprotein receptors targeting strategy. Mannose, a water-soluble carbohydrate, was hydrophobized by anchoring stearylamine with an objective to conjugate mannose on the surface of curcumin loaded nanostructured lipid carriers for targeting asialoglycoprotein receptors on hepatocytes. Mannose conjugated stearylamine was synthesized and characterized using various analytical techniques. The synthesized targeting ligand was incorporated curcumin loaded nanostructured lipid carriers and characterized by photon correlation spectroscopy. Zeta potential measurement was used to confirm the conjugation of the synthesized ligand to the surface of drug-loaded nanostructured lipid carriers. CCl4 induced hepatotoxicity in male Wistar rats was used as an experimental animal model to evaluate the hepatoprotective potential of formulated drug encapsulated nanostructured lipid carriers. The hepatoprotective potential was assessed by measuring serum liver injury markers and oxidative stress parameters in the liver post–mitochondrial supernatant. Mannose conjugated nanostructured lipid carriers showed acceptable particle size which revealed its suitability for hepatocyte targeting. In addition to this, mannose conjugated nanocarriers revealed significantly better (p < 0.05) reduction of serum liver injury markers and proinflammatory cytokines compared to the unconjugated one which confirmed hepatocytes targeting potential of the synthesized ligand. Asialoglycoprotein receptors targeting could be a landmark strategy for hepatocyte targeting. Thus, the synthesized mannose anchored stearylamine could be a promising novel targeting ligand having hepatocyte targeting potential. The asialoglycoprotein receptors can be utilized for hepatocyte targeting. NLCs are major lipid based carrier used for phytoactive delivery. NLCs are promising lipid carrier for hepatocyte targeting. Curcumin is most prominent antioxidant phytoactive with hepatoprotective potential.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) seriously affects human health, especially, it easily develops multi-drug resistance (MDR) which results in treatment failure. There is an urgent need to develop highly effective and low-toxicity therapeutic agents to treat HCC and to overcome its MDR. Targeted drug delivery systems (DDS) for cancer therapy, including nanoparticles, lipids, micelles and liposomes, have been studied for decades. Recently, more attention has been paid to multifunctional DDS containing various ligands such as polymer moieties, targeting moieties, and acid-labile linkages. The polymer moieties such as poly(ethylene glycol) (PEG), chitosan (CTS), hyaluronic acid, pullulan, poly(ethylene oxide) (PEO), poly(propylene oxide) (PPO) protect DDS from degradation. Asialoglycoprotein receptor (ASGPR) and glycyrrhetinic acid receptor (GAR) are most often used as the targeting moieties, which are overexpressed on hepatocytes. Acid-labile linkage, catering for the pH difference between tumor cells and normal tissue, has been utilized to release drugs at tumor tissue. OBJECTIVES This review provides a summary of the recent progress in ASGPR and GAR-mediated and/or pH-responsive HCC-targeted drug delivery. CONCLUSION The multifunctional DDS may prolong systemic circulation, continuously release drugs, increase the accumulation of drugs at the targeted site, enhance the anticancer effect, and reduce side effects both in vitro and in vivo. But it is rarely used to investigate MDR of HCC; therefore, it needs to be further studied before going into clinical trials.

Abstract
Diabetic wounds are one complication of persistent hyperglycemia and lead to neuropathy and vascular lesions in patients. The promotion of angiogenesis plays an important role in wound healing. Cell-free fat extract (Ceffe) is a cell-free fraction isolated from adipose that is enriched with a range of growth factors, the combination of which can synergistically induce angiogenesis. In this study, we prepared a wound dressing by loading Ceffe with the γ-PGA hydrogel (Ceffe-γ-PGA) to promote the healing of wounds in diabetic mice. The viscosity of Ceffe-γ-PGA was 9.2 pa s, and the water retention rate after 6 hours reached 50%. The slow-release effect of the Ceffe-γ-PGA hydrogel was investigated in vitro in PBS, and the cumulative release rate was 97% after 6 days. Water retention and viscosity analyses revealed that Ceffe-γ-PGA provided a moist environment for the wound surface. The therapeutic effect of the Ceffe-γ-PGA hydrogel on wound healing was studied in vivo in type-II diabetic male db/db mice. After 17 days of wound treatment, the wound area ratio of the Ceffe-γ-PGA group was reduced to 2% of the original, and the capillary density of the Ceffe-γ-PGA group reached 33 mm-2 and was 19 mm-2 higher than that of the untreated group. The cell proliferation rate in the Ceffe-γ-PGA group was 37% higher than that in the untreated group. These results support the use of this system as a promising therapeutic strategy for wound healing in patients with diabetes.

Abstract
To augment the antitumor efficacy and minimize the significant side effects of chemotherapeutic drugs on health organs, a novel albumin-mimicking nanodrug, which is based on zwitterionic poly(glutamatyl lysine-co-cysteine) peptides scaffold, is developed to enhance pH-triggered tumor targeting via prolonging circulation time and accelerating cellular internalization. Results showed that the internalization of the nanodrug by MCF-7 cells is much faster than that by Doxil and even comparable to that by free doxorubicin (Dox) at tumor microenvironmental pH 6.7, whereas the internalization of the nanodrug is only 27.4 ± 7.6% of the Doxil by RAW-264.7 cells. Moreover, the significantly prolonged circulation time of the "stealthy" nanodrug was also comparable to that of the long circulating Doxil. As a result, the accumulation of the nanodrug in the tumor is much higher than that in the liver and kidney before the circulation half-life, which is significantly different from most other nanodrugs accumulated in the liver and kidney in this time scale. The tumor inhibition rate of the nanodrug was much higher than that of Doxil (93.2 ± 3.0% vs 54.2 ± 6.5%) after 18 day treatment, while the average bodyweight of the mice treated by the nanodrug was 26.9 ± 6.7% higher than that by Doxil. This indicated that the synergetic effect of long circulation time and fast cellular internalization of the nanodrug can significantly augment tumor targeting. This method might rejuvenate the traditional chemotherapeutic treatment.

Abstract
Chaos and the natural evolution of tumor systems can lead to the failure of tumor therapies. Herein, we demonstrate that iridium oxide nanoparticles (IrOx ) possess acid-activated oxidase and peroxidase-like functions and wide pH-dependent catalase-like properties. The integration of glucose oxidase (GOD) unlocked the oxidase and peroxidase activities of IrOx by the production of gluconic acid from glucose by GOD catalysis in cancer cells, and the produced H2 O2 was converted into O2 to compensate its consumption in GOD catalysis owing to the catalase-like function of the nanozyme, thus resulting in the continual consumption of glucose and the self-supply of substrates to generate superoxide anion and hydroxyl radical. Moreover, IrOx can constantly consume glutathione (GSH) by self-cyclic valence alternation of IrIV and IrIII . These cascade reactions lead to a "butterfly effect" of initial starvation therapy and the subsequent pressure of multiple reactive oxygen species (ROS) to completely break the self-adaption of cancer cells.

Abstract
PLGA (poly(lactic-co-glycolic acid))-based nanoparticles (NPs) are promising drug carrier systems because of their excellent biocompatibility and ability for sustained drug release. However, it is not well understood how the kinetics of such drug delivery system perform in the retinal blood circulation as imaged in vivo and in real time. To answer this question, PLGA NPs were loaded either with lipophilic carbocyanine perchlorate (DiI) or hydrophilic Rhodamine 123 (Rho123) and coated with poloxamer 188 (P188): PLGA-DiI/P188 and PLGA-Rho123/P188. All particles had narrow size distributions around 130 nm, spherical shape and negative potential. Subsequently, we performed in vivo real-time imaging of retinal blood vessels, combined with ex vivo microscopy to monitor the kinetics and to detect location of those two fluorescent markers. We found that DiI signals were long lasting, detectable >90 min in blood vessels after intravenous injection as visible by homogeneous labelling of the vessel wall as well as by spots in the lumen of blood vessels. In contrast, Rho123 signals mostly disappeared after 15 min post intravenous injection in such compartment. To explore how PLGA NP-loaded cargoes are released in the retina in vivo, we thereafter monitored the Cyanine5.5 amine (Cy5.5) covalently linked PLGA polymer (Cy5.5-PLGA) in parallel to DiI and Rho123. The Cy5.5 signal from PLGA polymer was detectable in the retina vessels >90 min for both, the Cy5.5-PLGA-DiI/P188 and Cy5.5-PLGA-Rho123/P188 groups. Microscopy of the ex vivo retina tissue revealed partial level of colocalization of PLGA with DiI but no colocalization between PLGA and Rho123 at 2 h post injection. This indicates that at least a fraction of the lipophilic DiI was preserved within NPs, whereas no hydrophilic Rho123 was associated with NPs at that time point. In conclusion, the properties of PLGA carrier-cargo system in the blood circulation of the retina might be strongly influenced by the combination of factors, including the individual properties of loaded compounds and blood milieu. Thus, it is unlikely that a single nanoparticle formulation will be identified that is universally effective for the delivery of different compounds.

Abstract
Site-specific delivery of chemotherapeutics specifically to neoplastic hepatocytes without affecting normal hepatocytes should be a focus for potential therapeutic management of hepatocellular carcinoma (HCC). The aptamer TLS 9a with phosphorothioate backbone modifications (L5) has not been explored so far for preferential delivery of therapeutics in neoplastic hepatocytes to induce apoptosis. Thus, the objective of the present investigation was to compare the therapeutic potential of L5-functionalized drug nanocarrier (PTX-NPL5) with those of the other experimental drug nanocarriers functionalized by previously reported HCC cell-targeting aptamers and non-aptamer ligands, such as galactosamine and apotransferrin. A myriad of well-defined investigations such as cell cycle analysis, TUNEL (terminal deoxynucleotidyltransferase-mediated deoxyuridine triphosphate nick end labeling) assay, and studies related to apoptosis, histopathology, and immunoblotting substantiated that PTX-NPL5 had the highest potency among the different ligand-attached experimental formulations in inducing selective apoptosis in neoplastic hepatocytes via a mitochondrial-dependent apoptotic pathway. PTX-NPL5 did not produce any notable toxic effects in healthy hepatocytes, thus unveiling a new and a safer option in targeted therapy for HCC. Molecular modeling study identified two cell-surface biomarker proteins (tumor-associated glycoprotein 72 [TAG-72] and heat shock protein 70 [HSP70]) responsible for ligand-receptor interaction of L5 and preferential internalization of PTX-NPL5 via clathrin-mediated endocytosis in neoplastic hepatocytes. The potential of PTX-NPL5 has provided enough impetus for its rapid translation from the pre-clinical to clinical domain to establish itself as a targeted therapeutic to significantly prolong survival in HCC.

Abstract
Cystic echinococcosis (CE), which is caused by the metacestode of Echinococcus granulosus, is one of the most important zoonoses affecting humans. Benzimidazoles (in particular albendazole) and praziquantel (PZQ) are effective against CE, but poor water solubility of these agents often leads to inadequate results. Here, we evaluate the effects of chitosan-albendazole (ChABZ) and chitosan-praziquantel (ChPZQ) nanoparticles as a new formulation on hydatid cysts both in vitro and in vivo. Developed microcysts in culture were treated with different concentrations of ChABZ and ChPZQ nanoparticles (either alone or in combination), and ABZ + PZQ suspension. The viability rate of microcysts was used to evaluate the drug efficacies. In addition, the prophylactic and therapeutic effects of the drugs were studied on infected DBA/2 mice. Transmission electron microscopy was used to observe the ultra-structural changes. The viability rate of microcysts and differences in cyst weights were compared by ANOVA, and the cyst numbers were compared using the Kruskal-Wallis test. The combination of ChABZ + ChPZQ nanoparticles was more effective than the ABZ + PZQ suspension in vitro (p < 0.05). In prophylaxy, a significant reduction was observed both in size and in number of the cysts in ChABZ + ChPZQ nanoparticle groups compared with the control group (p < 0.05). In the therapeutic stage, however, this treatment only reduced the cyst numbers. Degeneration of the microcysts treated with the drugs was evident in the ultra-structural imaging. Overall, the nanoparticulate drugs were more effective than their suspension counterparts, but further studies are recommended to evaluate the full potential of these nanoparticles in the treatment of human CE.

Abstract
Despite the advances in anticancer therapies, their effectiveness for many human tumors is still far from being optimal. Significant improvements in treatment efficacy can come from the enhancement of drug specificity. This goal may be achieved by combining the use of therapeutic molecules with tumor specific effects and delivery carriers with tumor targeting ability. In this regard, nucleic acid-based drug (NABD) and particularly small interfering RNAs (siRNAs), are attractive molecules due to the possibility to be engineered to target specific tumor genes. On the other hand, polymeric-based delivery systems are emerging as versatile carriers to generate tumor-targeted delivery systems. Here we will focus on the most recent findings in the selection of siRNA/polymeric targeted delivery systems for hepatocellular carcinoma (HCC), a human tumor for which currently available therapeutic approaches are poorly effective. In addition, we will discuss the most attracting and, in our opinion, promising siRNA-polymer combinations for HCC in relation to the biological features of HCC tissue. Attention will be also put on the mathematical description of the mechanisms ruling siRNA-carrier delivery, this being an important aspect to improve effectiveness reducing the experimental work.

Abstract
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-associated deaths worldwide. There is a lack of efficient therapy for HCC; the only available first-line systemic drug, sorafenib, can merely improve the average survival by two months. Among the efforts to develop an efficient therapy for HCC, nanomedicine has drawn the most attention, owing to its unique features such as high drug-loading capacity, intrinsic anticancer activities, integrated diagnostic and therapeutic functionalities, and easy surface engineering with targeting ligands. Despite its tremendous advantages, no nanomedicine can be effective unless it successfully targets the tumor site, which is a challenging task. In this review, the features of HCC are described, and the physiological hurdles that prevent nanoparticles from targeting HCC are discussed. Then, the surface physicochemical factors of nanoparticles that can influence targeting efficiency are discussed. Finally, a thorough description of the physiological barriers that nanomedicine must conquer before uptake by HCC cells if possible is provided, as well as the surface engineering approaches to nanomedicine to achieve targeted delivery to HCC cells. The physiological hurdles and corresponding solutions summarized in this review provide a general guide for the rational design of HCC targeting nanomedicine systems.

Abstract
In this study, novel glycyrrhetinic acid (GA) liposomes modified with a liver-targeting galactosylated derivative ligand (Gal) were prepared using a film-dispersion method. To characterize the samples, particle size, zeta potential, drug loading, and encapsulation efficiency were performed. Moreover, plasma and tissues were pre-treated by liquid-liquid extraction and analyzed by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results showed that the mean residence times (MRTs) and the area under the curve (AUC) of GA liposomes with Gal (Gal-GA-LP), and GA liposomes (GA-LP) were higher than the GA solution (GA-S) in plasma. The tissue (liver) distribution of Gal-GA-LP was significantly different in contrast to GA-LP. The relative intake rate (Re) of Gal-GA-LP and GA-LP in the liver was 4.752 and 2.196, respectively. The peak concentration ratio (Ce) of Gal-GA-LP and GA-LP in the liver was 2.796 and 1.083, respectively. The targeting efficiency (Te) of Gal-GA-LP and GA-LP in the liver was 48.193% and 34.718%, respectively. Taken together, the results indicate that Gal-GA-LP is an ideal complex for liver-targeting, and has great potential application in the clinical treatment of hepatic diseases. Drug loading and releasing experiments also indicated that most liposomes are spherical structures and have good dispersity under physiologic conditions, which could prolong GA release efficiency in vitro.

Abstract
Over the past ten years, the global biopharmaceutical market has remarkably grown, with ten over the top twenty worldwide high performance medical treatment sales being biologics. Thus, biotech R&D (research and development) sector is becoming a key leading branch, with expanding revenues. Biotechnology offers considerable advantages compared to traditional therapeutic approaches, such as reducing side effects, specific treatments, higher patient compliance and therefore more effective treatments leading to lower healthcare costs. Within this sector, smart nanotechnology and colloidal self-assembling systems represent pivotal tools able to modulate the delivery of therapeutics. A comprehensive understanding of the processes involved in the self-assembly of the colloidal structures discussed therein is essential for the development of relevant biomedical applications. In this review we report the most promising and best performing platforms for specific classes of bioactive molecules and related target, spanning from siRNAs, gene/plasmids, proteins/growth factors, small synthetic therapeutics and bioimaging probes.

Abstract
The photoswitching of photosensitive bolaamphiphiles based on thymine was investigated. Topochemical principles were applied to create light-responsive supra-amphiphiles by the utilisation of dynamic covalent bonds created by the photo-dimerisation of a DNA base, thymine. In order to induce the photo-dimerisation of thymine, two bolaamphiphilic molecules were designed and synthesised to meet the required [2 π+2 π] photo-cycloaddition conditions. The amphiphiles were synthesised with different spacers and their photo-reversibility and morphologies were studied by using UV/Vis, NMR and infrared spectroscopy, rheometry, dynamic light scattering and transmission electron microscopy.

Abstract
Sesamol is a phenolic component of sesame seed oil, which has been established as an antioxidant and also possesses potential for hepatoprotection. However, its protective role in carbon tetrachloride (CCl4 ) induced sub-chronic hepatotoxicity has not been studied. Limited oral bioavailability (BA) and rapid elimination (as conjugates) in rats is reported for sesamol. Considering its significant antioxidant potential and compromised BA, we packaged sesamol into solid lipid nanoparticles (S-SLNs) to enhance its hepatoprotective bioactivity. S-SLNs prepared by microemulsification method were nearly spherical in shape with an average particle size of 120.30 nm and their oral administration at 8 mg/kg body weight (BW) showed significantly (p < 0.001) better hepatoprotection than free sesamol (FS) and a well established hepatoprotective antioxidant silymarin [SILY (25 mg/kg BW); p < 0.05) in CCl4 induced sub-chronic liver injury in rats. Evaluations were done in terms of histological changes in the liver tissue, liver injury markers (serum alanine aminotransferase, serum aspartate aminotransferase, and serum lactate dehydrogenase); oxidative stress markers (lipid peroxidation, superoxide dismutase, and reduced glutathione) and proinflammatory response marker (tumor necrosis factor-alpha).

Abstract
UNLABELLED Hepatocellular carcinoma (HCC) has a fairly high morbidity and is notoriously difficult to treat due to long latent period before detection, multidrug resistance and severe drug-related adverse effects from chemotherapy. Targeted drug delivery systems (DDS) that can selectively deliver therapeutic drugs into tumor sites have demonstrated a great potential in cancer treatment, which could be utilized to resolve the limitations of conventional chemotherapy. Numerous preclinical studies of DDS have been published, but targeted DDS for HCC has yet to be made for practical clinical use. Since rational targeted DDS design should take cancer-specific properties into consideration, we have reviewed the biological and physicochemical properties of HCC extensively to provide a comprehensive understanding on HCC, and recent DDS studies on HCC, aiming to find some potential targeted DDSs for HCC treatment and a meaningful platform for further development of HCC treatments. FROM THE CLINICAL EDITOR Hepatocellular carcinoma has a high incidence worldwide and is known to be multidrug resistant. Thus, intensive research is being carried out to find better chemotherapeutic agents as well as new drug delivery systems. In this article, the authors reviewed in depth the current challenges facing new drug designs and also outlined novel targeted drug delivery systems (DDS) in the fight against HCC.

Abstract
Development of drug delivery systems, as much as the drug molecule itself, is an important consideration for improving drug absorption and bioavailability. The mechanisms by which drug carriers enter target cells can differ depending on their size, surface properties and components. Solid lipid nanoparticles (SLNs) have gained an increased attention in recent years and are the drug carriers of interest in this paper. They are known to breach the cell-membrane barrier and have been actively sought to transport biomolecules. Previous studies by our group, and also other groups, provided an extensive characterization of SLNs. However, few studies have investigated the uptake of SLNs and these have had limited mechanistic focus. The aim of this work was to investigate the pathway of uptake of SLNs by human epithelial cells i.e., lung A549 and cervical HeLa cells. To the best of our knowledge, this is first study that investigates the cellular uptake of SLNs by human epithelial cells. The mechanism of cellular uptake was deciphered using pharmacologic inhibitors (sucrose, potassium-free buffer, filipin and cytochalasin B). Imaging techniques and flow assisted cell sorting (FACS) were used to assess the cellular uptake of SLNs loaded with rhodamine 123 as a fluorescent probe. This study provided evidence that the cellular uptake of SLNs was energy-dependent, and the endocytosis of SLNs was mainly dependent on clathrin-mediated mechanisms. The establishment of entry mechanism of SLNs is of fundamental importance for future facilitation of SLNs as biological or drug carriers.

Abstract
BACKGROUND AND OBJECTIVES Curcumin, an established pleiotropic agent, has potential for hepatoprotection owing to its powerful antioxidant, anti-inflammatory, and antifibrogenic properties. However, its poor bioavailability limits its use in therapeutics. In this study, we aimed to package curcumin into solid lipid nanoparticles (C-SLNs) to improve its bioavailability and compare the efficacy of C-SLNs with that of free curcumin and silymarin, a well-established hepatoprotectant in clinical use, against carbon tetrachloride (CCl4)-induced hepatic injury in rats, post-induction. A self-recovery group to which no treatment was given was also employed for quantifying self-healing of hepatic tissue, if any. MATERIAL AND METHODS C-SLNs (particle size 147.6 nm), prepared using a microemulsification technique, were administered to rats post-treatment with CCl4 (1 ml/kg body weight [BW] twice weekly for 2 weeks, followed by 1.5 ml/kg BW twice weekly for the subsequent 2 weeks). The extent of liver damage and repair in terms of histopathology and levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), oxidative stress markers (malondialdehyde, superoxide dismutase, and reduced glutathione) and a pro-inflammatory response marker, tumor necrosis factor (TNF)-α, were determined in both the CCl4 group and the treatment groups. RESULTS C-SLNs (12.5 mg/kg) significantly (p < 0.001-0.005) attenuated histopathological changes and oxidative stress, and also decreased induction of ALT, AST, and TNF-α in comparison with free curcumin (100 mg/kg), silymarin (25 mg/kg), and self-recovery groups. CONCLUSION Curcumin could be used as a therapeutic agent for hepatic disorders, provided it is loaded into a suitable delivery system.

Abstract
Background Sesamol, a component of sesame seed oil, exhibited significant antioxidant activity in a battery of in vitro and ex vivo tests including lipid peroxidation induced in rat liver homogenates. Latter established its potential for hepatoprotection. However, limited oral bioavailability, fast elimination (as conjugates) and tendency towards gastric irritation/toxicity (especially forestomach of rodents) may limit its usefulness. Presently, we packaged sesamol into solid lipid nanoparticles (S-SLNs) to enhance its biopharmaceutical performance and compared the efficacy with that of free sesamol and silymarin, a well established hepatoprotectant, against carbon tetrachloride induced hepatic injury in rats, post induction. A self recovery group in which no treatment was given was used to observe the self-healing capacity of liver. Methods S-SLNs prepared by microemulsification method were administered to rats post-treatment with CCl4 (1 ml/kg body weight (BW) twice weekly for 2 weeks, followed by 1.5 ml/kg BW twice weekly for the subsequent 2 weeks). Liver damage and recovery on treatment was assessed in terms of histopathology, serum injury markers (alanine aminotransferase, aspartate aminotransferase), oxidative stress markers (lipid peroxidation, superoxide dismutase, and reduced glutathione) and a pro-inflammatory response marker (tumor necrosis factor alpha). Result S-SLNs (120.30 nm) at a dose of 8 mg/kg BW showed significantly better hepatoprotection than corresponding dose of free sesamol (FS; p < 0.001). Effects achieved with S-SLNs were comparable with silymarin (SILY), administered at a dose of 25 mg/kg BW. Self recovery group confirmed absence of regenerative capacity of hepatic tissue, post injury. Conclusion Use of lipidic nanocarrier system for sesamol improved its efficiency to control hepatic injury. Enhanced effect is probably due to: a) improved oral bioavailability, b) controlled and prolonged effect of entrapped sesamol and iii) reduction in irritation and toxicity, if any, upon oral administration. S-SLNs may be considered as a therapeutic option for hepatic ailments as effectiveness post induction of liver injury, is demonstrated presently.

Abstract
We investigated the therapeutic effectiveness of the nanoparticle-encapsulated curcumin (CUR-NP) against sodium arsenite-induced hepatic oxidative damage in rats. The CUR-NP prepared by emulsion technique was spherical in shape with an encapsulation efficiency of 86.5%. The particle size ranged between 120 and 140 nm with the mean particle size being 130.8 nm. Rats were divided into five groups of six each. Group 1 served as control. Group 2 rats were exposed to sodium arsenite (25 ppm) daily through drinking water for 42 days. Groups 3, 4, and 5 were treated with arsenic as in group 2, however, they were administered, empty nanoparticles, curcumin (100 mg/kg bw) and CUR-NP (100 mg/kg bw), respectively, by oral gavage during the last 14 days of arsenic exposure. Arsenic increased the activities of serum alanine aminotransferase and aspartate aminotransferase and caused histological alterations in liver indicating hepatotoxicity. Arsenic increased lipid peroxidation, depleted reduced glutathione and decreased the activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase in liver. All these effects of arsenic were attenuated with both curcumin and CUR-NP. However, the magnitude of amelioration was more pronounced with CUR-NP. The results indicate that curcumin given in nano-encapsulated form caused better amelioration than free curcumin. © 2013 Wiley Periodicals, Inc. Environ Toxicol 30: 628-637, 2015.

Abstract
Patients with hepatocellular carcinoma (HCC) usually present at advanced stages and do not benefit from surgical resection, so drug therapy should deserve a prominent place in unresectable HCC treatment. But chemotherapy agents, such as doxorubicin, cisplatin, and paclitaxel, frequently encounter important problems such as low specificity and non-selective biodistribution. Recently, the development of nanotechnology led to significant breakthroughs to overcome these problems. Decorating the surfaces of nanoparticulate-based drug carriers with homing devices has demonstrated its potential in concentrating chemotherapy agents specifically to HCC cells. In this paper, we reviewed the current status of active targeting strategies for nanoparticulate systems based on various receptors such as asialoglycoprotein receptor, transferrin receptor, epidermal growth factor receptor, folate receptor, integrin, and CD44, which are abundantly expressed on the surfaces of hepatocytes or liver cancer cells. Furthermore, we pointed out their merits and defects and provided theoretical references for further research.

Abstract
Lanreotide is an octapeptide analog of endogenous somatostatin, specifically binding with tumors over-express somatostatin receptor 2 (SSTR2). In this study, we conjugated lanreotide to 1, 2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy (poly-(ethylene glycol))-2000] (PEG-DSPE), constructed active targeted micelles (lanreotide-PM), characterized their in vitro and in vivo targeting effect, and explored the receptor mediated transportion. The uptake of lanreotide-PM was found to be related to the expression level of SSTR2 in different cell lines and the competitive inhibition phenomenon indicated that the cellular uptake of lanreotide-PM was via a receptor meditated mechanism. In vivo, more lanreotide-PM accumulated in SSTR2 high expression tumor xenografts, endocytosed by the tumor cells, induced more apoptosis of tumor cells, and suppressed tumor growth efficiently. In conclusion, lanreotide-modified micelles containing antitumor drugs provide a promising strategy for the treatment of SSTR-expressing tumors.

Abstract
Peptide dendrimers have shown promise as an attractive platform for drug delivery. In this study, mPEGylated peptide dendrimer-doxorubicin (dendrimer-DOX) conjugate-based nanoparticle is prepared and characterized as an enzyme-responsive drug delivery vehicle. The drug DOX is conjugated to the periphery of dendrimer via an enzyme-responsive tetra-peptide linker Gly-Phe-Leu-Gly (GFLG). The dendrimer-DOX conjugate can self-assemble into nanoparticle, which is confirmed by dynamic light scattering, scanning electron microscopy, and transmission electron microscopy studies. At equal dose, mPEGylated dendrimer-DOX conjugate-based nanoparticle results in significantly high antitumor activity, and induces apoptosis on the 4T1 breast tumor model due to the evidences from tumor growth curves, an immunohistochemical analysis, and a histological assessment. The in vivo toxicity evaluation demonstrates that nanoparticle substantially avoids DOX-related toxicities and presents good biosafety without obvious side effects to normal organs of both tumor-bearing and healthy mice as measured by body weight shift, blood routine test, and a histological analysis. Thus, the mPEGylated peptide dendrimer-DOX conjugate-based nanoparticle may be a potential nanoscale drug delivery vehicle for the breast cancer therapy.

Abstract
Specific drug delivery to solid tumors remains one of the challenges in cancer therapy. The aim of this study was to combine three drug-targeting strategies, polymer-drug conjugate, ligand presentation and ultrasound treatment, to enhance the efficacy and selectivity of doxorubicin (DXR) to hepatoma cells. The conjugation of DXR to γ-poly(glutamic acids) (γ-PGA) decreased the cytotoxicity of DXR, while the conjugation of galactosamine (Gal) to the γ-PGA-DXR conjugate restored the cytotoxic efficacy of DXR on hepatoma cells due to increased uptake of DXR. Furthermore, low-intensity ultrasound treatment increased the cell-killing ability of γ-PGA-DXR conjugates by 20%. The in vitro results showed the potential of the γ-PGA-DXR-Gal conjugate for future clinical applications.

Abstract
Arsenic exposure through drinking water causes oxidative stress and tissue damage in the kidney and brain. Curcumin (CUR) is a good antioxidant with limited clinical application because of its hydrophobic nature and limited bioavailability, which can be overcome by the encapsulation of CUR with nanoparticles (NPs). The present study investigates the therapeutic efficacy of free CUR and NP-encapsulated CUR (CUR-NP) against sodium arsenite-induced renal and neuronal oxidative damage in rat. The CUR-NP prepared by emulsion technique and particle size ranged between 120 and 140 nm, with the mean particle size being 130.8 nm. Rats were divided into five groups (groups 1–5) with six animals in each group. Group 1 served as control. Group 2 rats were exposed to sodium arsenite (25 ppm) daily through drinking water for 42 days. Groups 3, 4, and 5 were treated with arsenic as in Group 2; however, these animals were also administered with empty NPs, CUR (100 mg/kg body weight), and CUR-NP (100 mg/kg), respectively, by oral gavage during the last 14 days of arsenic exposure. Arsenic exposure significantly increased serum urea nitrogen and creatinine levels. Arsenic increased lipid peroxidation (LPO), reduced glutathione content and the activities of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase were depleted significantly in both kidney and brain. Treatment with free CUR and CUR-NP decreased the LPO and increased the enzymatic and nonenzymatic antioxidant system in kidney and brain. Histopathological examination showed that kidney and brain injury mediated by arsenic was ameliorated by treatment. However, the amelioration percentage indicates that CUR-NP had marked therapeutic effect on arsenic-induced oxidative damage in kidney and brain tissues.

Abstract
We have synthesized poly-γ-glutamic acid (PGA) modified with a synthetic trivalent glyco-ligand (TriGalNAc) for the hepatocyte asialoglycoprotein receptor (ASGP-R). We investigated in vivo distribution of unmodified PGA and TriGalNAc-modified PGA (TriGalNAc-PGA) in mice after intravenous injection. Most of unmodified PGA administered was transported to the bladder over 20-80min, suggesting a rapid excretion of unmodified PGA into urine. In contrast, TriGalNAc-PGA was found exclusively in the liver over the same period of time. We further synthesized TriGalNAc-PGA-primaquine conjugate (TriGalNAc-PGA-PQ), and investigated binding, uptake, and catabolism of the conjugate by rat hepatocytes. Our studies indicated that approximately 250ng per million cells of the conjugate bound to one million rat hepatocytes at 0°C, and approximately 2μg per million cells of the conjugate was taken up over 7h incubation at 37°C. Furthermore, our results suggested that TriGalNAc-PGA-PQ was almost completely degraded over 24h, and small degradation products were secreted into cell culture medium. The results described in this report suggest that the TriGalNAc ligand can serve as an excellent targeting device for delivery of PGA-conjugates to the liver hepatocytes, and rat hepatocytes possess sufficient capacity to digest PGA even modified with other substituents.

Abstract
To improve the treatment of helminthiasis, filariasis, and colorectal cancer, albendazole-associated chitosan nanoparticles (ABZ-CS-NPs) were prepared using the emulsion crosslinking volatile technique with contained sodium tripolyphosphate as the crosslinking agent and Poloxamer 188 as the auxiliary solvent. The structural characteristics of the NPs were determined using X-ray diffraction to analyze the interaction between CS and the drug. The NPs were then evaluated in terms of their physicochemical characteristics, drug release behavior, in vivo pharmacokinetic parameters, and biodistribution in animal studies. ABZ-loaded NPs with a uniformly spherical particle sizes (157.8 ± 2.82 nm) showed efficient drug loading, encapsulated efficiency, and high physical stability. The drug release from ABZ-CS-NPs was extended over several periods. Kinetic models were then fitted to determine the release mechanisms. ABZ and its metabolite albendazole sulfoxide (ABZSX) were analyzed in rats with mebendazole as the internal standard using reversed-phase high-performance liquid chromatography. Compared with the ABZ suspension groups, the relative bioavailability values of ABZ and ABZSX were 146.05 and 222.15%, respectively. In addition, the plasma concentration versus time curve is consistent with that of the two compartment models in the plasma concentration versus time curve. The results indicate that the ABZ-loaded NPs are promising novel ABZ candidates for passive diffusion in the treatment of hydatid cysts in the liver via oral administration.

Abstract
Polymers bearing pendant galactosyl group are attractive for targeted intracellular antitumor drug delivery to hepatoma cells (e.g. HepG2 and SMMC7721 cells) with asialoglycoprotein receptor (ASGP-R). Herein, a series of galactopeptides was synthesized through ring-opening polymerization of L-glutamate N-carboxyanhydride, deprotection of benzyl group and subsequent Huisgens cycloaddition "click" reaction with azide-modified galactosyl group. The copolypeptides were revealed to have excellent hemocompatibilities, and cell and tissue compatibilities, which rendered their potential for drug delivery applications. The hepatoma-targeted micellar nanoparticle (i.e. nanomedicine) was fabricated by cooperative self-assembly of galactopeptide and doxorubicin (DOX) induced by two-stage physical interactions. In vitro DOX release from nanomedicine was accelerated in the intracellular acidic condition. Through the recognition between galactose ligand and ASGP-R of HepG2 cells, the endocytosis of galactosylated nanomedicine was significantly promoted, which was demonstrated by confocal laser scanning microscopy and flow cytometry. Remarkably, the galactose-decorated nanomedicine retained much higher antitumor activity toward HepG2 cells in contrast to the nanomedicine without galactosyl group in vitro and in vivo. The above superiorities indicated that the galactosylated nanomedicine possessed great promising for hepatoma-targeted chemotherapy.

Abstract
The purpose of this investigation was to design novel pentablock copolymers (polylatide-polycaprolactone-polyethylene glycol- polycaprolactone-polylatide) (PLA-PCL-PEG-PCL-PLA) to prepare nanoparticle formulations which provide continuous delivery of steroids over a longer duration with minimal burst effect. Another purpose was to evaluate the effect of poly (L-lactide) (PLLA) or poly (D, L-lactide) (PDLLA) incorporation on crystallinity of pentablock copolymers and in vitro release profile of triamcinolone acetonide (selected as model drug) from nanoparticles. PLA-PCL-PEG-PCL-PLA copolymers with different block ratio of PCL/PLA segment were synthesized. Release of triamcinolone acetonide from nanoparticles was significantly affected by crystallinity of the copolymers. Burst release of triamcinolone acetonide from nanoparticles was significantly minimized with incorporation of proper ratio of PDLLA in the existing triblock (PCL-PEG-PCL) copolymer. Moreover, pentablock copolymer based nanoparticles exhibited continuous release of triamcinolone acetonide. Pentablock copolymer based nanoparticles can be utilized to achieve continuous near zero-order delivery of corticosteroids from nanoparticles without any burst effect.

Abstract
Regeneration of nerve tissue is one of the most significant challenges in contemporary surgical therapy for nervous system injury. This study presents the neuronal differentiation of induced pluripotent stem (iPS) cells in hydrogels comprising alginate and poly(γ-glutamic acid) (γ-PGA) with surface neuron growth factor (NGF). Differentiating iPS cells in NGF-grafted alginate/γ-PGA constructs were identified by immunochemical staining of anti-SSEA-1 and anti-β III tubulin. The results revealed that the pore diameter of hydrogels increased with an increasing weight ratio of alginate to γ-PGA. The porosity slightly decreased with an increasing weight ratio of alginate to hydrogel. In addition, an increase in the weight ratio of alginate to hydrogel raised the swelling ratio. Morphological images of differentiating iPS cells in NGF-grafted alginate/γ-PGA constructs exhibited neuronal characteristics. The surface NGF enhanced the intensity of β III tubulin and inhibited the intensity of SSEA-1 expressed by differentiating iPS cells in cultured constructs, indicating the differentiation of iPS cells toward neurons. NGF-grafted alginate/γ-PGA hydrogels can be efficient biomaterials in the production of neurons from iPS cells for animal study and preclinical trial.

Abstract
Background Polylactic-co-glycolic acid (PLGA) nanoparticles have been used to increase the relative oral bioavailability of hydrophobic compounds and polyphenols in recent years, but the effects of the molecular weight of PLGA on bioavailability are still unknown. This study investigated the influence of polymer molecular weight on the relative oral bioavailability of curcumin, and explored the possible mechanism accounting for the outcome. Methods Curcumin encapsulated in low (5000–15,000) and high (40,000–75,000) molecular weight PLGA (LMw-NPC and HMw-NPC, respectively) were prepared using an emulsification-solvent evaporation method. Curcumin alone and in the nanoformulations was administered orally to freely mobile rats, and blood samples were collected to evaluate the bioavailability of curcumin, LMw-NPC, and HMw-NPC. An ex vivo experimental gut absorption model was used to investigate the effects of different molecular weights of PLGA formulation on absorption of curcumin. High-performance liquid chromatography with diode array detection was used for quantification of curcumin in biosamples. Results There were no significant differences in particle properties between LMw-NPC and HMw-NPC, but the relative bioavailability of HMw-NPC was 1.67-fold and 40-fold higher than that of LMw-NPC and conventional curcumin, respectively. In addition, the mean peak concentration (Cmax) of conventional curcumin, LMw-NPC, and HMw-NPC was 0.028, 0.042, and 0.057 μg/mL, respectively. The gut absorption study further revealed that the HMw-PLGA formulation markedly increased the absorption rate of curcumin in the duodenum and resulted in excellent bioavailability compared with conventional curcumin and LMw-NPC. Conclusion Our findings demonstrate that different molecular weights of PLGA have varying bioavailability, contributing to changes in the absorption rate at the duodenum. The results of this study provide the rationale for design of a nanomedicine delivery system to enhance the bioavailability of water-insoluble pharmaceutical compounds and functional foods.

Abstract
In this paper, two novel liver-targeting nanoparticles, norcantharidin-loaded chitosan nanoparticles (NCTD-CS-NPs) and norcantharidin-associated galactosylated chitosan nanoparticles (NCTD-GC-NPs), were prepared using ionic cross-linkage. The physical properties, particle size, encapsulation efficiency, and drug release characteristics of the nanoparticles were investigated in vitro. To investigate the intestinal absorption mechanisms of the two preparations, a series of experiments was carried out, including in situ circulation method, in vitro everted gut sacs, and Ussing chamber perfusion technique. The absorption rate constants (Ka) of NCTD at different segments were found to be duodenum > jejunum > ileum > colon. The concentration had no distinctive effect on absorption kinetics, suggesting that drug absorption is not dose-dependent. The transport of NCTD was found to be inhibited by P-glycoprotein (P-gp) inhibitor, indicating that NCTD might be the substrate of P-gp. The order of the absorption enhancer effects were as follows: low molecular weight chitosan (CS-8kDa) > high molecular weight chitosan (CS-30kDa) > Poloxamer > sodium dodecyl sulfate (SDS) > sodium deoxycholate (SDCh). The results indicate that the chitosan nanoparticles can improve intestinal absorption of NCTD.
