Abstract
In the present work, chrysin loaded bilosomes were formulated, characterized and evaluated to enhance the hepatoprotective activity of drug. Accordingly, chrysin loaded bilosomes were prepared by applying the thin film hydration method; also, fractional factorial design was used to optimize the production conditions of nanoformulations. The prepared formulations were subjected to different methods of characterization; then the hepatoprotective activity of the optimized one was evaluated in the CCl4 hepatointoxicated mice model. Optimized chrysin loaded bilosomes showed a spherical shape with a particle size of 232.97 ± 23 nm, the polydispersity index of 0.35 ± 0.01, the zeta potential of -44.5 ± 1.27 mv, the entrapment efficiency of 96.77 ± 0.18%, the drug loading % of 6.46 ± 0.01 and the release efficiency of 42.25 ± 1.04 during 48 h. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging assay demonstrated the superiority of the anti-oxidant potential of chrysin loaded bilosomes, as compared to pure chrysin. This was in agreement with histopathological investigations, showing significant improvement in serum hepatic biomarkers of CCl4 intoxicated mice treated with chrysin loaded bilosomes, as compared with free chrysin. These results, thus, showed the potential use of bilosomes to enhance the hepatoprotective activity of chrysin via oral administration.

Abstract
Background and purpose The present study aimed to obtain a taste-masked oral disintegrating tablet (ODT) containing tolterodine tartrate (TT) intercalated into montmorillonite (MMT). Experimental approach The TT-MMT hybrid was prepared by ion exchange reaction. The effect of the initial concentration of TT, MMT, temperature, and pH on the encapsulation efficiency (EE) % of the drug in MMT was evaluated. The selected TT-MMT hybrid was characterized by X-ray diffraction (XRD), Fourier transforms infrared (FTIR), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). Then, the optimized TT-MMT hybrid was incorporated in the ODT prepared by direct compression method and taste-masking assessment performed by a human test panel. Findings/Results The EE% of TT was in the range of 22.67 to 71.06% in different formulations. It was found that increases in MMT concentration significantly increased EE%. DSC and XRD studies indicated that the TT was intercalated in the MMT interlayer space in an amorphous or molecular state. In-vitro release studies at pH 6.8 showed that the amount of the drug released from the TT-MMT hybrid was negligible for the first 3 min. The post-compression of ODT also showed satisfactory results in terms of friability, hardness, disintegration time, and taste. Conclusion and implications MMT-ODT could be a suitable vehicle for the taste masking of TT, with the potential for use in patients with swallowing problems.

Abstract
The most common form of leishmaniasis is cutaneous leishmaniasis (CL). The major difficulties in the treatment of leishmaniasis include emergence of resistance, toxicity, long-term treatment, and the high cost of the current drugs. Although the therapeutic effect of sorafenib (SF) has been demonstrated in both in vitro and in vivo models of Leishmania infection, the therapeutic applications are limited due to severe drug-related toxicity; this is, in turn, due to non-specific distribution in the body. Thus, topical delivery has the advantage of the site directed delivery of SF. This research study evaluated SF-loaded hybrid nanofibers (NFs) which were composed of polycaprolactone (PCL) and cellulose acetate (CA) for the CL topical treatment. Accordingly, SF-loaded hybrid NFs were prepared using the electrospinning method. Formulation variables including total polymer concentration, drug/polymer ratio, and CA concentration were optimized using a full factorial design. The prepared SF-loaded NFs were then characterized for morphology, diameter, encapsulation efficiency (EE)%, drug loading (DL) %, and percentage of release efficiency during a 24-h period (RE24h%); the mechanical characteristics were also considered. The physical state of the drug in the optimized NF was evaluated by the X-ray diffraction analysis. Finally, its in vivo efficacy was determined in L. major-infected mice. The optimized formulation had a smooth, cylindrical, non-beaded shape fiber with a diameter of 281.44 nm, EE of 97.96%, DL of 7.48%, RE of 51.05%, ultimate tensile strength of 1.08 MPa, and Young's moduli of 74.96 MPa. The XRD analysis also demonstrated the amorphous state of SF in NF. Further, the in vivo results displayed the higher anti-leishmanial activity of the SF-loaded hybrid NF by efficiently healing lesion and successfully reducing the parasite burden. This, thus, indicated the potential of the clinical capability of the SF-loaded hybrid NF for the effective treatment of CL.

Abstract
Background and purpose Azithromycin (AZ) is a macrolide antibiotic that is soluble in saliva pH; its bitter taste can be well sensed, decreasing the ability of the patient to get the drug. Thus, handling such a bitter taste is challenging in developing the oral formulation. A wide range of methods has been applied to tackle this problem. Cubosomes are considered nanoparticles forming cubic three-dimensional structures with a taste-masking effect. This research aimed to apply cubosomes to mask AZ's bitter taste. Experimental approach Cubosomes which contained AZ were obtained by applying the film hydration method. Design expert software (version 11) was then employed for optimizing cubosomes that contained the drug. The encapsulation efficiency, particle size as well as polydispersity index of drug-loaded cubosomes were then subjected to evaluation. Assessment of particle morphology was done through SEM. The antimicrobial qualities of AZ-loaded cubosomes were then assessed by utilizing the disc diffusion method. Then, the taste masking study was carried out by referring to human volunteers. Finding/Results AZ-loaded cubosomes were spherical in terms of shape and in the 166-272 nm range, with a polydispersity index of 0.17-0.33 and encapsulation efficiency of 80-92%. The results related to the microbial culture revealed that the antimicrobial qualities related to AZ-loaded cubosomes were like those of AZ. The results obtained by taste evaluation also revealed that the cubosomes could well mask the drug's bitter taste. Conclusion and implications These findings, thus, revealed that while the antimicrobial impact of AZ is not under the influence of loading in cubosomes, its taste could be well improved.

Abstract
In this study, an emulsion solvent evaporation method was used to produce Eudragit RL (ERL) nanoparticles (NPs) loaded with simvastatin (SIM) for the treatment of ulcerative colitis (UC). Accordingly, the effects of different formulation variables on the properties of NPs were evaluated using the Box-Behnken design. The optimized NPs were then coated by Eudragit FS30D (EFS30D). Drug release was studied in different physiological environments. Colitis was induced by 3% of acetic acid in rats, which received NPs of SIM (10 mg/kg/day), mesalazine (150 mg/kg/day), blank NPs and normal saline orally for 5 days. Macroscopic histopathological evaluation and biochemical analysis, including myeloperoxidase (MPO) activity and malondialdehyde (MDA) level in the colon tissues, were carried out in this study. The optimized SIM-ERL NPs showed the particle size of 182.48 ± 4.57 nm, the polydispersity index of 0.29 ± 0.12, the zeta potential of 26.45 ± 4.57 mV, drug loading % of 34.64 ± 0.48, the encapsulation efficiency % of 98.68 ± 0.69, and the release efficiency % of 35.78 ± 1.37. Coating the optimized NPs with EFS30D caused an increase in particle size and a decrease in the zeta potential of NPs. The optimized SIM-EFS30D/RL NPs improved the macroscopic and histopathological scores. Also, MPO activity and MDA level were reduced significantly by NPs, as compared to the control group. Therefore, this drug delivery system can be an alternative to the previous treatments of UC.

Abstract
In the present study, gefitinib loaded cellulose acetate butyrate nanoparticles (Gnb-NPs) were prepared and then incorporated into thermo-sensitive chitosan/β-glycerophosphate hydrogels for intratumoral administration in mice bearing breast cancer. Accordingly, Gnb-NPs were prepared using the solvent evaporation process and optimized by applying a two-level fractional factorial design. Properties of NPs, including particle size, zeta potential (ZP), polydispersity index (PdI), encapsulation efficiency (EE) % and drug loading (DL) %, were investigated; the optimized Gnb-NPs were then loaded in chitosan hydrogels (Gnb-NPs-Hydrogel). The formulated Gnb-NPs-Hydrogel was assessed in terms of gelling time, release behavior, injectability, swelling and degradation behavior. The anti-cancer efficacy of Gnb-NPs-Hydrogel was evaluated in vitro against the 4 T1 breast cancer cell line and in vivo in breast tumor bearing mice. The optimized formulation showed spherical particles with the size of 156.50 ± 2.40 nm, PdI of 0.20 ± 0.002, ZP of -4.90 ± 0.04 mV, EE of 99.77 ± 0.09 % and DL of 20.59 ± 0.05 %. Incorporating Gnb-NPs into the hydrogel led to the decrease of the drug release rate. Gnb-NPs-Hydrogel displayed a greater cytotoxic effect in comparison to the free Gnb and Gnb-Hydrogel in 4 T1 cancer cells. Furthermore,intratumorallyinjectedGnb-NPs-Hydrogel showed the strongest antitumor efficacy in vivo. The superior performance of Gnb-NPs-Hydrogel, thus, demonstrated its potential for the treatment of breast cancer.

Abstract
In this study, a novel wafer based on Hydroxypropyl methylcellulose (HPMC) was prepared as a wound dressing for the simultaneous delivery of phenytoin (PT) and insulin; evaluation of the cutaneous wound repair property was performed too. Due to its low water solubility, PT was encapsulated in polymeric micelles (PM) by the film hydration method at different polymer/drug ratios and characterized in terms of particle size (PS), polydispersity index (PdI), zeta potential (ZP), drug loading (DL) %, entrapment efficiency (EE) %, and drug release. Then, the optimized PT loaded PM (PT-PM) was embedded in the wafers prepared from the HPMC polymer, alone or in combination with Carbopol 940 (CB) and xanthan gum (XG). This wafer also contained a fixed amount of insulin (PT-PM-Insulin-wafer). The obtained wafers were evaluated in terms of morphology, water uptake ability, porosity, bioadhesion and hardness features. Finally, the efficacy of the PT-PM-Insulin-wafer was assessed in full-thickness excision wound models. The optimized PT-PM showed the PS of 84.05 ± 1.80 nm, PdI of 0.28 ± 0.22, ZP of -3.38 ± 0.26 mV, DL of 15.63 ± 0.01%, EE of 92.66 ± 0.08%, and the release efficiency of 59.95 ± 0.03%. The results obtained from the XRD studies of PT-PM also demonstrated the transition of the crystalline nature of the PT to the amorphous form, while FTIR studies showed some intermolecular interaction of PT and the Soluplus® copolymer chain. It was also found that the incorporation of XG into HPMC wafers influenced the microstructure, thus increasing the porosity, water uptake ability and bioadhesion. Compared with other groups, the PT-PM-Insulin-wafer group showed the enhancement of wound closure through increasing collagen deposition and re-epithelialization. The present study, therefore, revealed that the PT-PM-Insulin-wafer group might have very promising applications for wound healing.

Abstract
In the current study, a composite in-situ gel formulation containing aripiprazole (APZ) loaded transfersomes (TFS) was developed for the intranasal brain targeting of APZ. APZ loaded TFS were prepared by applying the film hydration method and optimized using an irregular factorial design. The prepared formulations were optimized based on different parameters including particle size, polydispersity index (PdI), zeta potential, encapsulation efficiency (EE) and release efficiency (RE). The optimized APZ-TFS were distributed in an ion-triggered deacetylated gellan gum solution (APZ-TFS-Gel) and evaluated in terms of pH, gelling time, rheological properties and in-vitro release study. The therapeutic efficacy of the best APZ-TFS-Gel was then tested in the mice model of schizophrenia induced by ketamine by evaluating various behavioral parameters. The optimized formulation showed the particle size of 72.12 ± 0.72 nm, the PdI of 0.19 ± 0.07, the zeta potential of -55.56 ± 1.9 mV, the EE of 97.06 ± 0.10%, and the RE of 70.84 ± 1.54%. The in-vivo results showed that compared with the other treatment groups, there was a considerable increase in swimming and climbing time and a decrease in locomotors activity and immobility time in the group receiving APZ-TFS-Gel. Thus, APZ-TFS-Gel was found to have desirable characteristics for therapeutic improvement.

Abstract
In this study, hesperidin (HPN) loaded polyacrylonitrile (PAN)/polyethylene oxide (PEO) electrospun nanofibers were prepared for use as wound dressing. Accordingly, HPN loaded hybrid nanofibers were generated via electrospinning. A full factorial design was then applied to evaluate the influence of formulation variables including PEO amount, HPN amount and total polymer amount on the nanofiber features. Fabricated membranes were evaluated in terms of morphology, diameter, entrapment efficiency (EE) %, drug loading (DL) %, release efficiency (RE) %, swelling % and mechanical properties. Analysis of the obtained data showed that the amount of PEO was the most effective factor impacting the swelling and release percentage; by raising the amount of PEO from 20% to 40%, the swelling % and release rate were considerably increased. The optimized nanofibers were found to be non-beaded, smooth and cylindrical with fiber diameter of 126.14 ± 23.96 nm, EE% of 38.58 ± 6.06, DL% of 5.36 ± 0.83, swelling % of 859.90 ± 33.49, RE % of 78.49 ± 0.21, UTS of 0.79 ± 0.13 MPa and Young's moduli of 20.91 ± 2.13 MPa. The physical state of HPN in optimized hybrid nanofibers was examined and the related XRD analysis revealed that HPN was either molecularly dispersed, or it existed in an amorphous state in the nanofibers. The in vivo studies also demonstrated that the wound healing rate in the case of HPN loaded nanofibers was higher when compared with other groups. Moreover, according to H&E and MT stain results, HPN loaded nanofibers did promote the regeneration of skin more effectively, as compared with HPN -free nanofibers. Overall, HPN loaded nanofibers mats prepared in this study have the potential to serve as wound dressings.

Abstract
BACKGROUND Using imatinib, a tyrosine kinase inhibitor drug used in lymphoblastic leukemia, has always had limitations due to its cardiotoxicity and hepatotoxicity side effects. The objective of this study is to develop a target-oriented drug carrier to minimize these adverse effects by the controlled release of the drug. METHODS KIT-5 nanoparticles were functionalized with 3-aminopropyltriethoxysilane and conjugated to rituximab as the targeting agent for the CD20 positive receptors of the B-cells. Then they were loaded with imatinib and their physical properties were characterized. The cell cytotoxicity of the nanoparticles was studied by MTT assay in Ramos (CD20 positive) and Jurkat cell lines (CD20 negative) and their cellular uptake was shown by fluorescence microscope. Wistar rats received an intraperitoneal injection of 50 mg/kg of the free drug or targeted nanoparticles for 21 days. Then the level of aspartate Aminotransferase (AST), alanine Aminotransferase (ALT), Alkaline Phosphatase (ALP) and Lactate Dehydrogenase (LDH) were measured in serum of animals. The cardiotoxicity and hepatotoxicity of the drug were also studied by hematoxylin and eosin staining of the tissues. RESULTS The targeted nanoparticles of imatinib showed to be more cytotoxic to Ramos cells rather than Jurkat cells. The results of the biochemical analysis displayed a significant reduction in AST, ALT, ALP, and LDH levels in animals treated with targeted nanoparticles, compared to the free drug group. By comparison with the free imatinib, histopathological results represented less cardiotoxicity and hepatotoxicity in the animals, which received the drug through the current designed delivery system. CONCLUSION The obtained results confirmed that the rituximab targeted KIT-5 nanoparticles are promising in the controlled release of imatinib and could decrease its cardiotoxicity and hepatotoxicity side effects.

Abstract
Cutaneous leishmaniasis is known as the most prevalent clinical form of leishmaniasis. It needs the development of new therapies due to the serious side-effects promoted by taking the current drugs. In the present study, dextran-behenic acid (DEX-BA) based nanomicelles were developed to direct the delivery of itraconazole (ITZ) to the macrophages and enhance its toxic effects against Leishmania parasites. DEX-BA was synthesized through the esterification of dextran with behenic acid. The critical micelle concentration of the newly developed conjugate was evaluated using pyrene as the fluorescent probe. The nanomicelles were generated by the dialysis method; then they were optimized by applying a Box-Behnken design. The effects of the dialysis temperature, polymer content, and sonication time on the characteristics of micelles were subsequently studied. Furthermore, in vitro efficacy against Leishmania major promastigotes and parasite-infected macrophages was evaluated. The optimized formulation showed the particle size of 195.16 ± 3.06 nm, the polydispersity index of 0.39 ± 0.01, the zeta potential of -16.29 ± 0.89 mV, the encapsulation efficiency % of 56.11 ± 4.9, and the release efficiency % of 51.29 ± 1.97. According to scanning electron microscopy, the nanomicelles were found to be nearly spherical in shape. ITZ-loaded nanomicelles showed the strongest anti-leishmanial activities when compared with the free ITZ and drug-free nanomicelles. It could be, therefore, concluded that ITZ-loaded nanomicelles might be useful as an alternative therapy for the treatment of cutaneous leishmania.

Abstract
A dual pH- and time-dependent polymeric coated capsule was developed to achieve the site specificity of simvastatin (SIM) release in the colon. To improve the SIM solubility, soluplus-based nanosuspension of the drug were prepared by applying the anti-solvent crystallization technique; this was then followed by lyophilization. Particle size, polydispersity index, and saturation solubility were evaluated. The optimized nanosuspension was combined with SLS and freeze-dried before filling into hard gelatin capsules. Drug release characteristics of the coated capsules were studied in HCl 0.1 N, the phosphate buffers 6.8 and 7.4, and the simulated colonic fluid (pH 6.8). The in-vitro cytotoxic effects of SIM nanoparticles against HT29 cells were then evaluated using the MTT assay. The prepared nanoparticles were spherical with a mean size of 261.66 nm, the zeta potential of -18.20 and the dissolution efficiency of 59.71%. X-ray diffraction and differential scanning calorimetry studies showed that the nanosizing technique transformed the crystalline drug into the more soluble amorphous form. The coated capsules had no release in the gastric media, providing the specific delivery of SIM in the colon. The cytotoxic effect of the SIM nanoparticles was significantly increased, as compared to the free SIM. The findings, therefore, showed that the coated capsules using the two polymers of ethyl cellulose and Eudragit S100 could be suitable for the colon target delivery of SIM.

Abstract
The objective of this study was to develop an in-situ gel containing lorazepam (LZM) loaded nanostructured lipid carriers (NLCs) for direct nose-to-brain delivery in order to increase drug therapeutic efficacy in the treatment of epilepsy. Accordingly, LZM loaded NLCs were formulated using emulsification solvent diffusion and evaporation method; then the effects of the formulation variables on different physicochemical characteristics of NLCs were investigated. Thermosensitive in-situ gels containing LZM-NLCs were prepared using a combination of chitosan and β-glycerol phosphate (β-GP). The anticonvulsant efficacy of LZM-NLCs-Gel was then examined using the pentylenetetrazole (PTZ) model. The optimised NLCs were spherical, showing the particle size of 71.70 ± 5.16 nm and the zeta potential of -20.06 ± 2.70 mV. The pH and gelation time for the chitosan solution with 15% (w/v) β-GP were determined to be 7.12 ± 0.03 and 5.33 ± 0.58 min, respectively. The in-vivo findings showed that compared with the control group and the group that received LZM-Gel, the occurrence of PTZ-induced seizures in the rats was significantly reduced by LZM-NLCs-Gel after intranasal administration. These results, therefore, suggested that the LZM-NLCs-Gel system could have potential applications for brain targeting through nasal route and might increase LZM therapeutic efficacy in the treatment of epilepsy.

Abstract
In the present study, imatinib-loaded transfersomal gel (imatinib-TFS-Gel) was developed to minimize the oral dosing frequency and side effects during rheumatoid arthritis (RA) therapy. Imatinib-loaded transfersomes (imatinib-TFS) were prepared by the film-hydration method. The effects of lecithin content, lecithin/ EA ratio, and the type of EA on the characteristics of the imatinib-TFS were studied using a D-optimal design. Morphology of imatinib-TFS was investigated using scanning electron microscopy. The optimized imatinib-TFS formulation was used to prepare imatinib-TFS-Gel with the aid of Carbopol 940 as the gelling agent. The Optimized imatinib-TFS had a spherical shape with the particle size of 140.53 ± 0.87 nm, polydispersity index of 0.44 ± 0.01, the zeta potential of -17.63 ± 0.65 mV, encapsulation efficiency of 98.70 ± 0.38%, and release efficiency of 81.26 ± 0.70 %. Ex-vivo skin permeation studies through the rat skin showed that the cumulative amount of imatinib permeated from imatinib-TFS-Gel was significantly higher than that from imatinib-Gel. The RA rat model indicated a substantial reduction in paw edema during the 14 days study following the application of imatinib-TFS-Gel as compared with imatinib-Gel. Therefore, imatinib-TFS-Gel can be considered as a promising drug delivery system for the treatment of RA.

Abstract
Gefitinib as an epidermal growth factor receptor tyrosine kinase inhibitor has strong potential in lung cancer therapy. However, a major challenge of using gefitinib is its toxicities. In the present study, we developed a dry powder inhaler dosage form containing gefitinib loaded glucosamine targeted solid lipid nanopaticles (Gef-G-SLNs) to locally transfer anticancer agent to the lung tumor. The Gef-G-SLNs were prepared by emulsion-solvent diffusion and evaporation method and optimized with irregular factorial design. The optimized nanoformulation was tested for action against A549 cells. Mannitol or lactose based dry powders were obtained from Gef-G-SLNs after spray drying and characterized using Anderson Cascade Impactor. The optimized formulation had drug loading of 33.29%, encapsulation efficiency of 97.31 ± 0.23%, zeta potential of -15.53 ± 0.47 mV, particle size of 187.23 ± 14.08 nm, polydispersity index of 0.28 ± 0.02 and release efficiency of 35.46 ± 2.25%. The Gef-G-SLNs showed superior anticancer effect compared to free gefitinib. The increased cellular uptake of G-SLNs in A549 cells was demonstrated compared with non-targeted SLNs using flow cytometry and fluorescence microscopy. The produced mannitol based microparticles showed suitable aerodynamic properties with an acceptable mass median aerodynamic diameter of 4.48 µm and fine particle fraction of 44.41%. Therefore, it can be concluded that this formulation represents promising drug delivery to treatment of lung cancer.

Abstract
The present study aimed to prepare and investigate the wound healing potential of carboxymethyl cellulose (CMC)-based wafers incorporated with resveratrol (RSV)-loaded cellulose acetate butyrate (CAB) NPs. Accordingly, RSV-CAB NPs were prepared using the solvent evaporation method. The effect of different formulation parameters (polymer content, surfactant concentration, and the volume ratio of aqueous phase to organic phase) on the properties of NPs was investigated using the Box-Behnken design. Then, the optimized NPs were incorporated in wafers comprising CMC combined with hydroxyl propyl methyl cellulose (HPMC) or chitosan. Hydration capacity, porosity, adhesive strength, and hardness of the prepared nanocomposite wafers were examined. Optimized formulation was spherical, showing the particle size, polydispersity index, zeta potential, encapsulation efficiency %, drug loading %, and release efficiency % of 248.5 nm, 0.38, - 1.59, 87.58, 25.94, and 67.10, respectively. The CMC-HPMC wafers exhibited higher porosity, hydration capacity, and adhesive performance, as compared with the CMC wafers alone and CMC-chitosan wafers. Wound healing test and histological evaluation in the excisional wounds of the rats showed that the RSV-NPs-wafers were more effective as a healing accelerator, in comparison to wafers without drug or those containing the free RSV. These results demonstrated the potential of the RSV-NPs-wafer in wound healing drug delivery applications. Graphical abstract.

Abstract
BACKGROUND Among the numerous bio-responsive polymeric drug delivery systems developed recently, redox-triggered release of molecular payloads have gained great deal of attention, especially in the field of anticancer drug delivery. In most cases, these systems rely on disulfide bonds located either in the matrix crosslinks, or in auxiliary chains to achieve stimuli-responsive drug release. These bonds keep their stability in extracellular environments, yet, rapidly break by thiol-disulfide exchange reactions in the cytosol, due to the presence of greater levels of glutathione. Polysaccharides are macromolecules with low cost, natural abundance, biocompatibility, biodegradability, appropriate physical and chemical properties, and presence of numerous functional groups which facilitate chemical or physical cross-linking. METHODS With regards to the remarkable advantages of polysaccharides, in the current study, various polysaccharide-based redox-responsive drug delivery systems are reviewed. In most cases the in vitro/in vivo effects of the developed system were also evaluated. RESULTS Considering the hypoxic and reducing nature of the tumor microenvironment, with several folds higher glutathione levels than the systemic tissues, redox-sensitive polymeric systems could be implemented for tumorspecific drug delivery and the results of the previous researches in this field indicated satisfactory achievements. CONCLUSION According to the reviewed papers, the efficiency of diverse redox-responsive polysaccharide-based nanoparticles with therapeutic payloads in cancer chemotherapy could be concluded. Nevertheless, more comprehensive studies are required to understand the exact intracellular and systemic fate of these nano-carriers, as well as their clinical efficacy for cancer treatment.

Abstract
Present investigation aimed to prepare, optimise, and characterise lipid nanocapsules (LNCs) for improving the solubility and bioavailability of efavirenz (EFV). EFV-loaded LNCs were prepared by the phase-inversion temperature method and the influence of various formulation variables was assessed using Box-Behnken design. The prepared formulations were characterised for particle size, polydispersity index (PdI), zeta potential, encapsulation efficiency (EE), and release efficiency (RE). The biocompatibility of optimised formulation on Caco-2 cells was determined using 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay. Then, it was subjected to ex-vivo permeation using rat intestine. EFV-loaded LNCs were found to be spherical shape in the range of 20-100 nm with EE of 82-97%. The best results obtained from LNCs prepared by 17.5% labrafac and 10% solutol HS15 when the volume ratio of the diluting aqueous phase to the initial emulsion was 3.5. The mean particle size, zeta potential, PdI, EE, drug loading%, and RE during 144 h of optimised formulation were confirmed to 60.71 nm, -35.93 mV, 0.09, 92.60, 7.39 and 55.96%, respectively. Optimised LNCs increased the ex vivo intestinal permeation of EFV when compared with drug suspension. Thus, LNCs could be promising for improved oral delivery of EFV.

Abstract
Background: A simple and sensitive reversed-phase high-performance liquid chromatography (HPLC) method based on liquid-liquid extraction was established and validated for determination of docetaxel (DTX) in plasma of rat. Materials and Methods: Samples were spiked with paclitaxel as the internal standard and the chromatographic separation was carried out using C18 HPLC column. The mobile phase consisted of a mixture of acetonitrile/water with the ratio of 60/40 v/v. The ultraviolet detector was operated at 230 nm, and the flow rate of mobile phase was 1 ml/min. The method was validated for linearity, precision, accuracy, recovery, and limit of quantification (LOQ). Then the method was applied to quantify DTX in the rat plasma after intravenous (IV) administration of the self-assembled micelles of folate-targeted Synpronic F127/cholesterol (FA-PF127-Chol) loaded with DTX and Taxotere® as the reference marketed solution of DTX. The blood samples were taken from the ophthalmic vein at predetermined time intervals after treatment. Results: Calibration curve was linear between the concentration ranges of 0.1–7.5 μg/ml with the relative standard deviation % and evaluating error % ranged from 2.263 to 15.53 and −12.75 to 12.7 for intra- and inter-day validity, respectively. The mean recovery of the drug after plasma extraction was 95.67 ± 0.99% for the concentration of 1 μg/ml. The LOQ and the limit of detection for DTX in serum were 100 ng/ml and 30 ng/ml, respectively. Conclusions: The results indicated that the developed method could be adopted for pharmacokinetic studies of DTX-loaded FA-PF127-Chol micelles and Taxotere® in rat.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease with complex pathology characterized by inflammation of joints, devastation of the synovium, pannus formation, bones and cartilage destruction and often is associated with persistent arthritic pain, swelling, stiffness and work disability. In conventional RA therapy, because of short biological half-life, poor bioavailability, high and frequent dosing is required. Thereby, these anti-RA medications, which unable to selectively target affected zone, may cause severe side effects in extra-articular tissues. Today, nanotechnology has emerged as promising tool in the development of novel drug delivery systems for the treatment and diagnosis of intractable diseases such as RA. Active targeting in RA nanomedicine has also been introduced a successful way for facilitating specific uptake of therapeutic agents by the disease cells. In this review, it is attempted to describe various targeted drug delivery systems (localized and receptor-based) used for RA diagnosis and therapy. Then, we highlight recent developments related to various non-viral gene delivery systems for RA gene therapy.

Abstract
Inhalable dry powders containing poly lactic-co-glycolic acid (PLGA) nanoparticles (NPs) were developed for the delivery of tadalafil (TAD) for treatment of life-treating pulmonary arterial hypertension. Taguchi design was employed to evaluate the effects of different formulation variables on the physicochemical characteristics of PLGA-NPs prepared using emulsion solvent evaporation method. Inhalable PLGA-NPs of TAD were successfully prepared by co-spray drying the PLGA-NPs with inert carriers. Physicochemical characteristics and in vitro deposition of the aerosolized drug were also evaluated. The optimized formulation was prepared using 7.5 mg of PLGA, 2.5 mg of TAD, sonication time of 6 min and 2% polyvinyl alcohol (PVA) as the stabilizer. The optimized aqueous/oil phase ratio for PLGA-NPs preparation was 10:1. Polymer/drug ratio was the most effective parameter on the release efficiency. Encapsulation efficiency, zeta potential and particle size of PLGA-NPs were more affected by aqueous/organic phase ratio. The spray dried powders containing PLGA-NPs had a mass median aerodynamic diameter (MMAD) in the range of 1.4–2.8 μm that was suitable for TAD delivery to the deep region of lung. The presence of L- leucine in mannitol containing formulations decreased the interparticulate forces between particles and increased significantly the process yield and fine particle fraction (FPF). The results indicated that prepared dry powders containing TAD-loaded PLGA-NPs were suitable for inhalation and has the potential for the treatment of pulmonary arterial hypertension.

Abstract
BACKGROUND Niosomes are non-ionic surfactant vesicles used as drug carriers for encapsulating both hydrophobic and hydrophilic drugs. The aim of this study is to evaluate the effect of different surfactants on the physical properties and stability of carvedilol niosomes designed to improve oral bioavailability. MATERIALS AND METHODS Different niosomal formulations were prepared using a film hydration method, with various mixtures of different non-ionic surfactants including Span 20, 40, and 60, and also Tween 20, 40, and 60, along with cholesterol. The physicochemical characteristics of the formulations were evaluated in vitro. RESULTS The drug encapsulation efficiency was reduced by using lauryl (C12) chain containing surfactants, that is, Span/Tween. Cholesterol content and drug entrapment were the main factors affecting the mean particle size of the niosomes. The drug release profiles from most of the formulations were fitted well with the Baker-Lonsdale model, indicating a diffusion-based drug release mechanism. Niosomes prepared from 50 and 40% of the cholesterol with 25 or 30% of Span/Tween 60 showed the highest stability due to their high transition temperature and solid state feature of these surfactants. CONCLUSIONS From the results obtained, it may be concluded that nanoniosomes are promising stable carriers for the oral delivery of carvedilol.

Abstract
Polymeric micelles (PMs) were formulated as nano carriers for docetaxel intended for both intravenous administration and improve therapeutic efficacy of the drug. The PMs were formulated using folic acid conjugated Synpronic F127-cholesterol copolymer and were optimised using a 2(3) full factorial design. The effects of different formulation variables were evaluated on the particle size, entrapment efficiency (EE), zeta potential and release efficiency of the micelles. The in vitro cytotoxicity of DTX-loaded FA targeted micelles was studied on B16F10 melanoma cells which over expressed FA receptor. Among the studied single factors, solvent type was the most effective parameter on the EE and release efficiency. Polymer/drug ratio had the most considerable effect on the particle size while, zeta potential was more affected by temperature. Finally, the PMs with polymer/drug ratio of 12 prepared at 25°C by dimethyl sulfoxide as the dialyzing solvent was shown to be the optimum formulation with desirability factor of 84.9%. The optimised formulation exhibited a particle size of 171.3 nm, 99.59% drug EE, zeta potential of -7.80 mV, drug release efficiency of about 70% at 144 h and polydispersity index of 0.32. The MTT assay indicated DTX-loaded FA targeted micelles were significantly more cytotoxic than non-targeted micelles and free drug.

Abstract
Melanoma is a life threatening disease with a growing incidence rate. It is estimated that 9840 patients will die from melanoma in 2014. Despite numerous attempts for treating metastatic melanoma, conventional therapies including systemic chemotherapy or immunotherapy, either as single agents or combined, have not been promising. The most cytotoxic agents have low molecular weight, which leads to rapid excretion, nonspecific distribution, and poor therapeutic index. Therefore, they may even increase toxicity due to their non-specific action on healthy tissue that can exacerbate the malady. To provide optimum effective concentration, multiple-dose drug administration is required, which again can increase the incidence of adverse effects. Recent developments in drug delivery systems are able to improve the drug efficacy and safety, and offer more promising approaches in treating melanoma. Recent researches have shed more light on the advantages of novel drug loaded carrier systems versus free drugs. Most of these animal studies, reported improvement in treatment efficacy and survival rate using novel carrier systems. This is related to the ability of these systems in enhancing the anticancer effect by modifying drug pharmacokinetics and biodistribution, selective target delivery of the agents to the diseased tissue and their ability to cross the biological barriers. In this paper, it is attempted to illustrate the potentials of novel strategies in treatment of melanoma incorporating drug delivery systems versus conventional therapies.

Abstract
The objective of the present study was to prepare a micellar polymeric carrier for the delivery of Docetaxel (DTX) as a kind of polysorbate free preparation. Pluronic F127 (PF127) was conjugated to cholesterol (Chol) via succinyl linkage and characterized by FTIR and HNMR. DTX-loaded polymeric micelles were prepared via film hydration method. Physicochemical properties of micelles including particle size, zeta potential, drug loading and release efficiency were studied. The critical micelle concentration (CMC) was determined using pyrene as a hydrophobic fluorescent probe. In vitro cytotoxicity of micelles was evaluated in B16F10 melanoma cells and HepG2 cell line. The FTIR and HNMR spectroscopy methods confirmed the conjugation of PF127 to cholesterol via succinyl linkage. The micelles were spherical under scanning electron microscope (SEM) with the mean particle size of 248.2 ± 8-278.8 ± 12.3 nm and zeta potential ranging from -17.2 ± 8.7 to -28.4 ± 12.7 mV. Drug loading efficiency was higher than 98%. The in vitro release study showed the sustained release behavior of DTX within 144 h. The CMC of the micelles was about 41.67 ± 0.17 µg/ml, which was significantly lower than the CMC of pure PF127 micelles. Compared with the free drug, DTX-loaded micelles showed higher cytotoxicity against B16F10 melanoma and HepG2 cell lines.

Abstract
The objective of the present study was to prepare a stable iv injectable formulation of ascorbic acid and α-tocopherol in preventing the cerebral ischemia. Different niosomal formulations were prepared by Span and Tween mixed with cholesterol. The physicochemical characteristics of niosomal formulations were evaluated in vitro. For in vivo evaluation, the rats were made ischemic by middle cerebral artery occlusion model for 30 min and the selected formulation was used for determining its neuroprotective effect against cerebral ischemia. Neuronal damage was evaluated by optical microscopy and transmission electron microscopy. The encapsulation efficiency of ascorbic acid was increased to more than 84% by remote loading method. The cholesterol content of the niosomes, the hydrophilicity potential of the encapsulated compounds, and the preparation method of niosomes were the main factors affecting the mean volume diameter of the prepared vesicles. High physical stability of the niosomes prepared from Span 40 and Span 60 was demonstrated due to negligible size change of vesicles during 6 months storage at 4-8(°)C. In vivo studies showed that ST60/Chol 35 : 35 : 30 niosomes had more neuroprotective effects against cerebral ischemic injuries in male rats than free ascorbic acid.
