Abstract
The gut microbiota plays a significant role in the pathogenesis and remission of inflammatory bowel disease. However, conventional antibiotic therapies may alter microbial ecology and lead to dysbiosis of the gut microbiome, which greatly limits therapeutic efficacy. To address this challenge, novel nanomicelles that couple inulin with levofloxacin via disulfide bonds for the treatment of salmonellosis were developed in this study. Owing to their H2S-responsiveness, the nanomicelles can target the inflamed colon and rapidly release levofloxacin to selectively fight against enteric pathogens. Moreover, the embedded inulin can serve as prebiotic fiber to increase the amount of Bifidobacteria and Lactobacilli in mice with salmonellosis, thus maintaining the intestinal mechanical barrier and regulating the balance of the intestinal flora. Therefore, multifunctional nanomicelles had a better curative effect than pure levofloxacin on ameliorating inflammation in vivo. The pathogen-targeted glycovesicle represents a promising drug delivery platform to maximize the efficacy of antibacterial drugs for the treatment of inflammatory bowel disease.

Abstract
Fungal infections of cornea are important causes of blindness especially in developing nations with tropical climate. However, the challenges associated with current treatments are responsible for poor outcome. Natamycin is the only FDA-approved antifungal drug to treat fungal keratitis, but unfortunately due to its poor water solubility, it is available as suspension. The marketed suspension (5% Natamycin) has rapid precorneal clearance, poor corneal permeability, a higher frequency of administration, and corneal irritation due to undissolved suspended drug particles. In our study, we developed clear and stable natamycin-loaded nanomicelles (1% Natcel) to overcome the above challenges. We demonstrated that 1% Natcel could permeate the cornea better than 5% suspension. The developed 1% Natcel was able to provide sustained release for up to 24 h. Further, it was found to be biocompatible and also improved the mean residence time (MRT) than 5% suspension in tears. Therefore, the developed 1% Natcel could be a potential alternative treatment for fungal keratitis.

Abstract
The goal of this investigation is to develop stable ophthalmic nanoformulations containing cannabidiol (CBD) and its analog cannabidiol-valine-hemisuccinate (CBD-VHS) for improved ocular delivery. Two nanoformulations, nanoemulsion (NE) and nanomicelles (NMC), were developed and evaluated for physicochemical characteristics, drug-excipient compatibility, sterilization, thermal analysis, surface morphology, ex-vivo transcorneal permeation, corneal deposition, and stability. The saturation solubility studies revealed that among the surfactants tested, Cremophor EL had the highest solubilizing capacity for CBD (23.3 ± 0.1 mg/mL) and CBD-VHS (11.2 ± 0.2 mg/mL). The globule size for the lead CBD formulations (NE and NMC) ranged between 205 and 270 nm while CBD-VHS-NMC formulation had a particle size of about 78 nm. The sterilized formulations, except for CBD-VHS-NMC at 40 °C, were stable for three months of storage (last time point tested). Release, in terms of CBD, in the in-vitro release/diffusion studies over 18 h, were faster from the CBD-VHS nanomicelles (38 %) compared to that from the CBD nanoemulsion (16 %) and nanomicelles (33 %). Transcorneal permeation studies revealed improvement in CBD permeability and flux with both formulations; however, a greater improvement was observed with the NMC formulation compared to the NE formulation. In conclusion, the nanoformulations prepared could serve as efficient topical ocular drug delivery platforms for CBD and its analog.

Abstract
The efficacy of injectable micellar carriers is hindered due to the disassembly of micelles into free surfactants in the body, resulting in their dilution below the critical micelle concentration (CMC). Copolymer micelles were developed to address this issue, containing a superhydrophilic zwitterionic block and a superhydrophobic block with a disulfide bond, which exhibited a CMC lower than conventional micellar carriers. Cleavable copolymers composed of 2-methacryloyloxyethyl phosphorylcholine (MPC) zwitterion and polycaprolactone CHLZW as the shell, with gold nanoparticles as their core, were studied to deliver doxorubicin to tumor cells while reducing the side effect of the free cytotoxic agent. The research focused on the impact of gold nanoparticles present in targeted TMT-micelles core on stability and in vivo bioavailability and sonotoxicity of the nanoparticles, as well as their synergistic effect on targeted chemotherapy. The nanomicelles prepared in this study demonstrated excellent biocompatibility and responsiveness to stimuli. PCL-SS-MPC nanomicelles displayed drug release in response to GSH and pH, resulting in high DOX release at GSH 10 mM and pH 5. Our findings, supported by MTT, flow cytometry, and confocal laser scanning microscopy, demonstrated that AuS-PM-TMTM-DOX micelles effectively induced apoptosis and enhanced cellular uptake in MCF7 and MDA-MB231 cell lines. The cytotoxic effects of AuS-PM-DOX/US on cancer cells were approximately 38 % higher compared to AuS-PM-DOX samples at a concentration of IC50 0.68 nM. This increase in cellular toxicity was primarily attributed to the promotion of apoptosis. The introduction of disulfide linkages in AuSNPs resulted in increased ROS production when exposed to ultrasound stimulation, due to a reduction in GSH levels. Compared to other commercially available nanosensitizers such as titanium dioxide, exposure of AuS-PM to ultrasound radiation (1.0 W/cm, 2 min) significantly enhanced cavitation effects and resulted in 3 to 5 times higher ROS production. Furthermore, laboratory experiments using human breast cancer cells (MDA-MB-231, MCF7) demonstrated that the toxicity of AuS-PM in response to ultrasound waves is dose-dependent. The findings of this study suggest that this formulated nanocarrier holds great potential as a viable treatment option for breast cancer. It can induce apoptosis in cancer cells, reduce tumor size, and display notable therapeutic efficacy.

Abstract
Cancer treatment is challenged due to immunosuppressive inflammatory tumour microenvironment (TME) caused by infiltration of tumour-promoting and inhibition of tumour-inhibiting immune cells. Here, we report the engineering of chimeric nanomicelles (NMs) targeting the cell proliferation using docetaxel (DTX) and inflammation using dexamethasone (DEX) that alters the immunosuppressive TME. We show that a combination of phospholipid-DTX conjugate and PEGylated-lipid-DEX conjugate can self-assemble to form sub-100 nm chimeric NMs (DTX-DEX NMs). Anti-cancer activities against syngeneic and xenograft mouse models showed that the DTX-DEX NMs are more effective in tumour regression, enhance the survival of mice over other treatment modes, and alter the tumour stroma. DTX-DEX NMs cause a significant reduction in myeloid-derived suppressor cells, alter the polarization of macrophages, and enhance the accumulation of cytotoxic CD4+ and CD8+ T cells in tumour tissues, along with alterations in cytokine expression. We further demonstrated that these DTX-DEX NMs inhibit the synthesis of prostaglandins, especially PGE2, by targeting the cyclooxygenase 2 that is partly responsible for immunosuppressive TME. Therefore, this study presents, for the first time, the engineering of lithocholic acid-derived chimeric NMs that affect the prostaglandin pathway, alter the TME, and mitigate tumour progression with enhanced mice survival.

Abstract
Glaucoma is known to be one of the principal causes of vision loss due to elevated intraocular pressure. Currently, latanoprost eye drops is used as first-line treatment for glaucoma; however, it possesses low bioavailability due to rapid precorneal clearance. A novel delivery system with a mucoadhesive property could overcome this problem. Therefore, we attempt to develop a combination of self-assembling latanoprost nanomicelles (Latcel) and a mucoadhesive polymer (N,O-carboxymethyl chitosan: N,O-CMC) to improve the corneal residence time. Latcel was developed using Poloxamer-407 by thin film hydration method, followed by the addition of N,O-CMC using simple solvation to obtain Latcel-CMC and characterized using various physicochemical characterization techniques. The particle size of Latcel-CMC was 94.07 ± 2.48 nm and a zeta potential of -16.03 ± 0.66 mV, with a sustained release for 24h whereas marketed latanoprost drops released 90 % of the drug within 1h. In vitro cytotoxicity studies, HET-CAM, and in vivo Draize test showed the biocompatibility of Latcel-CMC. Cellular uptake studies performed using fluorescein isothiocyanate (FITC) loaded nanomicelles in human corneal epithelial cells indicates the increased cellular uptake as compare to plain FITC solution. In vivo ocular residence time was evaluated in Wistar rats using Indocyanine green (ICG) loaded nanomicelles by an in vivo imaging system (IVIS), indicating Latcel-CMC (8h) has better residence time than plain ICG solution (2h). The Latcel-CMC showed improved corneal residence time and sustained release of latanoprost due to increased mucoadhesion. Thus, the developed N,O-Carboxymethyl chitosan based nanomicelles eye drop could be a better strategy than conventional eye drops for topical delivery of latanoprost to treat glaucoma.

Abstract
INTRODUCTION Research on nanotechnology in medicine has also involved the ocular field and nanomicelles are among the applications developed. This approach is used to increase both the water solubility of hydrophobic drugs and their penetration/permeation within/through the ocular tissues since nanomicelles are able to encapsulate insoluble drug into their core and their small size allows them to penetrate and/or diffuse through the aqueous pores of ocular tissues. AREAS COVERED The present review reports the most significant and recent literature on the use of nanomicelles, made up of both surfactants and amphiphilic polymers, to overcome limitations imposed by the physiology of the eye in achieving a high bioavailability of drugs intended for the therapeutic areas of greatest commercial interest: dry eye, inflammation, and glaucoma. EXPERT OPINION The results of the numerous studies in this field are encouraging and demonstrate that nanomicelles may be the answer to some of the challenges of ocular therapy. In the future, new molecules self-assembling into micelles will be able to meet the regulatory requirements for marketing authorization for their use in ophthalmic formulations.

Abstract
AIMS Rheumatoid arthritis (RA) is chronic inflammatory disorder mainly affects the lining of articular cartilage of synovial joints characterized by severe inflammation and joint damage. The expression of proteolytic enzymes like MMP-2 and Neutrophil Elastase (NE) worsens the RA condition. To address this concern, we have synthesized dual enzyme targeted chlorotoxin conjugated nanomicelles loaded with sivelestat as broad spectrum treatment for RA. MATERIALS AND METHODS Conjugation of the chlorotoxin over nanomicelle and incorporation of sivelestat in nanomicelle provide it dual targeting potential. The sivelestat loaded nanomicelle (SLM) evaluated for the drug release and in-vitro cytocompatibility. Further, investigated its in-vivo anti-arthritic potential on collagen-induced arthritis in wistar rats. KEY FINDINGS The microscopic observation of SLM showed spherical ball like appearance with size ranging from 190 to 230 nm. SLM showed good drug loading and encapsulation efficiency along with no cytotoxicity against healthy cell lines. In-vivo therapeutic assessment on collagen induced arthritis rat model showed potential chondroprotection. The microscopic visualization of articular cartilage by staining showed that it restores the cartilage integrity and lowers the expression of pro-inflammatory enzymes showed by Immunohistochemistry and Immunofluorescence. We observed that, it restrain the mediators of synovial inflammation by simultaneous inhibition of the proteolytic enzymes involved in swelling, cartilage destruction and joint damage which provides strong chondroprotection. SIGNIFICANCE We report that significant alleviation of inflammation and inhibition of proteolytic enzymes together might provide enhanced potential for the treatment and management of RA.

Abstract
Photodynamic therapy (PDT) is one common ROS-generating therapeutic method with high tumor selectivity and low side effects. But the GSH-upregulation often alleviates its therapeutic efficiency. Here, we proposed a new strategy of jointly depleting GSH to enhance the therapeutic effect of PDT by preparing a nanomicelle by self-assembly method from GSH-activated photosensitizer DMT, curcumin, and amphiphilic polymer TPGS.

Abstract
Arthritis is a chronic disease that affects, approximately, 1 % of the total global population. It is characterized by chronic inflammation, accompanied in most of the cases of motor disability and sever pain. The main therapies available have high risk of failure and advanced treatments are scarce and highly cost. In this scenario, search for effective, safe and low-cost treatments is quite desirable. Methyl gallate (MG) is a plant-derived phenolic compound described to present remarkable anti-inflammatory effect in experimental models of arthritis. Thus, in this study we formulated nanomicelles of MG using Pluronic (F-127) as matrix and evaluated in vivo the pharmacokinetic, biodistribution and its effect in the mice model of zymosan-induced arthritis. The nanomicelles were formed with a size 126 nm. The biodistribution showed a ubiquitous tissue deposition with a renal excretion. The pharmacokinetics showed elimination half-life of 1.72 h and a clearance of 0.006 L/h. The oral pretreatment with nanomicelles containing MG (3.5 or 7 mg/kg) demonstrated a reduction in total leukocytes, neutrophils, and mononuclear cells from the inflammation site. The data supports the use of methyl gallate nanomicelles as an alternative drug for arthritis. DATA AVAILABILITY: All the data of this study are transparent.

Abstract
Treatment of intervertebral disc (IVD) degeneration includes conservative and surgical strategies that have a high risk of recurrence. Consequently, tissue engineering represents a promising alternative treatment. This study aimed at healing damaged IVD with a bioimplant that can maintain the function of defected IVD. The developed IVD scaffold is composed of a fortified biocompatible gelatin-based hydrogel to mimic the ECM mechanical properties of IVD and to allow a sustained release of loaded bioactive agents. The hydrogel is laden with platelet-rich plasma (PRP) and simvastatin (SIM)-loaded mixed pluronics nanomicelles because of their regenerative ability and anti-inflammatory effect, respectively. The gelatin-based hydrogel attained swelling of 508.9 ± 7.9 % to 543.1 ± 5.9 % after 24 h. Increasing crosslinking degree of the hydrogel improved its mechanical elasticity up to 0.3 ± 0.1 N/mm2, and retarded its degradation. The optimum mixed nanomicelles had particle size of 84 ± 0.5 nm, a surface charge of -10 ± 7.1 mv, EE% of 84.9 %, and released 88.4 % of SIM after 21 days. Cytotoxicity of IVD components was evaluated using human skin fibroblast for 3 days. WST-test results proved biocompatibility of IVD scaffold. Subcutaneous implantation of the IVD scaffold was performed for 28 days to test in-vivo biocompatibility. Histological and histochemical micrographs depicted normal healing signs such as macrophages, T-cells, angiogenesis and granulation reactions. Introducing PRP in IVD improved healing process and decreased inflammation reactions. The developed multicomponent implant could be used as potential IVD scaffold with desirable mechanical properties, biocompatibility and healing process.

Abstract
Antiangiogenic therapy in combination with chemotherapeutic agents is an effective strategy for cancer treatment. However, this combination therapy is associated with several challenges including non-specific biodistribution leading to systemic toxicity. Biomaterial-mediated codelivery of chemotherapeutic and anti-angiogenic agents can exploit their passive and active targeting abilities, leading to improved drug accumulation at the tumor site and therapeutic outcomes. In this review, we present the progress made in the field of engineered biomaterials for codelivery of chemotherapeutic and antiangiogenic agents. We present advances in engineering of liposome/hydrogel/micelle-based biomaterials for delivery of combination of anticancer and anti-angiogenesis drugs, or combination of anticancer and siRNA targeting angiogenesis, and targeted nanoparticles. We then present our perspective on developing strategies for targeting angiogenesis and cell proliferation for cancer therapy.

Abstract
This study aimed to evaluate the effect of dual-frequency sonication in the presence of thalidomide angiogenesis inhibitor and nanomicelles containing doxorubicin on inhibiting the growth and angiogenesis of breast adenocarcinoma in BALB/c female mice. Sixty mice carrying the tumor were divided into 12 groups: (A) control, (B) 28 kHz and 3 MHz sonication, (C) thalidomide, (D) thalidomide and 28 kHz, (E) thalidomide and 3 MHz, (F) thalidomide and dual-frequency sonication, (G) doxorubicin, (H) nanomicelles containing doxorubicin, (I) nanomicelles containing doxorubicin and dual-frequency sonication, (J) thalidomide and doxorubicin, (K) thalidomide and nanomicelles containing doxorubicin, and (L) thalidomide and nanomicelles containing doxorubicin and dual-frequency sonication. The delay in the tumor growth and angiogenesis percent were extracted. Pathological and immunohistochemical studies were performed to confirm the treatment. The findings of tumor growth retardation parameters and animal survival were significantly different in group L from all groups (P < 0.05). The highest rate of inhibition was in group L with a 46% inhibition. In group L, 100% of the animals survived until day 49. In groups F, C, G, B, and A, all the animals survived 45, 42, 39, 32, and 30 days, respectively. Pathological results showed a decrease in tumor grade in groups K and L. Histopathological results demonstrate a decrease in group L angiogenesis compared to group C. These findings were consistent with the results of color Doppler ultrasound imaging. Dual-frequency sonication in the presence of thalidomide and doxorubicin-containing nanomicelles inhibits tumor growth and angiogenesis.

Abstract
Soluplus® nanomicelles have been widely reported in biomedical field for their excellent drug loading capacity and solubility enhancement ability. However, when administrated in vivo, the protein corona will be formed on Soluplus® nanomicelles, significantly affecting their drug delivery performance. Up to now, few studies examined the protein corona formation process and its impact factors of Soluplus® nanomicelles. The multiple proteins in biofluids may form protein corona in different modes due to their diversified properties. In this study, Bovine serum albumin (BSA), Lysozyme (Lyso) and Bovine hemoglobin (BHb) were chosen as model proteins to investigate the protein corona formation process of Soluplus® nanomicelles. By analyzing the polarity of the protein amino acid residues distributing microenvironments, the results showed that there were two different protein corona formation modes, i.e., surface adsorption and insertion, which were determined by the hydrophilicity of proteins. The hydrophobic BHb followed the insertion mode while hydrophilic BSA and Lyso followed the surface adsorption mode. Ultimately, upon protein corona formation, the size and surface chemistry of nanomicelles was significantly affected. We believe this study will provide a new research paradigm to the design and application of Soluplus® nanomicelles.

Abstract
Cerebral ischemia/reperfusion injury (CIRI) is closely related to mitochondrial dysfunction in astrocytes. Therefore, based on glucose transporter 1 (GLUT1), which is highly expressed in the brain tissue of rats with CIRI, we design a kind of brain-targeted dexmedetomidine (Man@Dex) nanomicelles. The results showed that Man@Dex not only had the advantages of small particle size, stability and non-toxicity, but also realized brain-targeted drug delivery. Primary astrocytes were cultured in vitro to construct CIRI cell model. It was found that Man@Dex could improve the activity of injured astrocytes. Man@Dex could exert antioxidant activity by inhibiting the reactive oxygen species (ROS) production of astrocytes, thus inhibiting the cytotoxicity induced by hypoxia and reoxygenation. Man@Dex could improve the ATP level and mitochondrial membrane potential (MMP) to protect mitochondrial function of damaged astrocytes. The CIRI rat model was constructed and confirmed by hematoxylin and eosin (HE), Triphenyl-2H-tetrazolium chloride (TTC) staining and nerve defect score. It indicated that Man@Dex could alleviate CIRI and improve MMP, which was beneficial to the recovery of brain injury in rats. This research provides a new theoretical basis and target for the development of brain-targeted nano-drugs of CIRI.

Abstract
Hepatocellular carcinoma (HCC) is one of the major cancers with high mortality rate. Traditional drugs used in clinic are usually limited by the drug resistance and side effect and novel agents are still needed. Macrolide brefeldin A (BFA) is a well-known lead compound in cancer chemotherapy, however, with poor solubility and instability. In this study, to overcome these disadvantages, BFA was encapsulated in mixed nanomicelles based on TPGS and F127 copolymers (M-BFA). M-BFA was conferred high solubility, colloidal stability, and capability of sustained release of intact BFA. In vitro, M-BFA markedly inhibited the proliferation, induced G0/G1 phase arrest, and caspase-dependent apoptosis in human liver carcinoma HepG2 cells. Moreover, M-BFA also induced autophagic cell death via Akt/mTOR and ERK pathways. In HepG2 tumor-bearing xenograft mice, indocyanine green (ICG) as a fluorescent probe loaded in M-BFA distributed to the tumor tissue rapidly, prolonged the blood circulation, and improved the tumor accumulation capacity. More importantly, M-BFA (10 mg/kg) dramatically delayed the tumor progression and induced extensive necrosis of the tumor tissues. Taken together, the present work suggests that M-BFA has promising potential in HCC therapy.

Abstract
Hesperetin (HSP) has excellent biological activities with poor water solubility which limits its clinical development. In this study, we successfully prepared a novel, self-assembled micelle based on Rebaudioside A (RA) for oral delivery of HSP with improved bioavailability and therapeutic effects. We found that RA and HSP could be formylated into nanomicelles with particle sizes of 4.541 nm ± 0.048 nm. HSP was readily encapsulated into RA micelles and this improved its water solubility (to 12.74 mg/mL ± 0.28 mg/mL). The MTT results showed that RA-HSP enhanced the cytotoxicity, the clonal formation inhibitory activity, and cell migration inhibitory activity of HSP in human breast cancer MDA-MB-231 cells. The mechanism results showed that RA-HSP induced cell apoptosis by inducing the production of reactive oxygen species (ROS), destroying the mitochondrial membrane potential (MMP), and inhibiting the PI3K/Akt signaling pathway. Moreover, RA-HSP enhanced the anticancer activity, increased the oral bioavailability and tissue distribution of HSP in vivo. Moreover, the mechanism studies in vivo found that HSP inhibited PI3K/Akt signaling pathway with low side effects. These findings indicate that RA micelle formulations have great potential in oral drug delivery systems for the delivery of hydrophobic drugs.

Abstract
Silver nanoparticles (AgNPs) are increasingly used in a wide range of products and as a consequence, the environmental concentration will inevitably increase in the near future. Many aquatic organisms have been shown to be sensitive to the toxic effects of silver, including oxidative stress mechanisms. In this study, we assessed the ability of silymarin (Silybum marianum) to counter the oxidative effects of AgNPs in Nile tilapia (Oreochromis niloticus). Fish were fed on the diets supplemented with 50 or 200 mg kg-1 of free or nanoencapsulated silymarin for 50 days. Subsequently, they were exposed via the water to three concentrations (0.05, 0.1, and 0.5 mg L-1) of AgNPs for 24 h, and the effects of this exposure assessed on blood plasma and liver oxidative status. Growth performance and most body indices measured were not affected by any of the experimental diets. There were no effects of free silymarin (FS) or nanoencapsulated silymarin (NS) on levels of plasma aspartate aminotransferase (AST), alanine transaminase (ALT), or on the total protein (TP). In contrast, malondialdehyde (MDA) content, glutathione peroxidase (GPx) activity, and plasma glucose (GLU) were all affected by the high dietary FS and NS treatments compared with controls. Prior to the AgNPs exposure, the levels of SOD and GPx activity were higher and MDA levels lower in the silymarin treatment groups compared to controls. Exposure to AgNPs resulted in a reduction in the levels of GPx and SOD activity and an increase in the level of MDA that was dependent on the exposure concentrations of AgNPs. Based on GPx, MDA, and GLU indices, both forms of silymarin decreased the toxicity of AgNPs, but NS supplementation was the most effective. Thus, we show dietary silymarin supplementation can reduce AgNP toxicity and nanoencapsulation increases its efficacy as an antioxidant.

Abstract
Integration of multiple therapies into one nanoplatform holds great promise to overcome the shortcomings of traditional single-modal therapy and achieve favorable antitumor efficacy. Herein, we constructed a dual receptor-targeting nanomicelle system with GSH-responsive drug release for precise fluorescence imaging and superior chemo-phototherapy of cancer. The synthetic amphiphilic hyaluronic acid derivative (FHSV) could self-assemble into nanomicelles in aqueous media. Then, paclitaxel (PTX) and photosensitizer IR780 iodide (IR780) were co-loaded into the micelles by a simple dialysis method. The resulting IR780/PTX/FHSV micelles with a particle size of 150.2 ± 6.9 nm exhibited excellent stability, GSH-responsive drug release and good photothermal/photodynamic efficacy. Once accumulated at the tumor sites, IR780/PTX/FHSV micelles efficiently entered tumor cells through receptor-mediated endocytosis and then rapidly release PTX and IR780 under GSH-rich tumor microenvironment. Upon NIR laser irradiation, IR780 produced local hyperthermia and sufficient reactive oxygen species to promote tumor cells apoptosis and necrosis. The results of in vitro and in vivo experiments consistently demonstrated that compared with single chemotherapy and phototherapy, the chemo-phototherapy could more efficiently kill tumor cells by synergistic antitumor effect. Therefore, our study provides a novel and efficient approach for multimodal treatment of malignant tumor.

Abstract
This work aimed to select an effective penetration enhancer (PE) for nail pretreatment, develop voriconazole (VOR)-loaded nanomicelles, and evaluate their ability to deliver VOR to the nail. A complete analysis of nail protein dynamics, bond rupture, and microstructure was performed. Alternative methods as electron paramagnetic resonance (EPR) and the Ellman's reagent (DTNB) assay were also evaluated. Nanomicelles were produced and characterized. The PE hydrated the hooves, following the order: urea ≈ cysteine ≈ glycolic acid < thioglycolic acid (TGA) < NaOH. SEM images and methylene blue assay showed enlarged pores and roughness of porcine hooves after incubation with NaOH and TGA. EPR was demonstrated to be the most sensitive technique. DTNB assay quantified higher thiol groups for samples treated with TGA (p < 0.05). A stratigraphic analysis with Raman spectroscopy demonstrated that hooves treated with TGA presented a higher SH/SS ratio at the edges, affecting protein secondary structure. In vitro permeation studies demonstrated significant VOR permeation (29.44 ± 6.13 µg/cm2), 10-fold higher than previous studies with lipid nanoparticles. After TGA pretreatment, VOR permeation was further enhanced (3-fold). TGA pretreatment followed by VOR-loaded nanomicelles demonstrates a promising approach for onychomycosis treatment. The novel methods for protein analysis were straightforward and helpful.

Abstract
Background Recently, we developed hydrophobically modified glycol chitosan (HGC) nanomicelles loaded with tacrolimus (TAC) (HGC-TAC) for the targeted renal delivery of TAC. Herein, we determined whether the administration of the HGC-TAC nanomicelles decreases kidney injury in a model of lupus nephritis. Lupus-prone female MRL/lpr mice were randomly assigned into three groups that received intravenous administration of either vehicle control, an equivalent dose of TAC, or HGC-TAC (0.5 mg/kg TAC) weekly for 8 weeks. Age-matched MRL/MpJ mice without Faslpr mutation were also treated with HGC vehicle and used as healthy controls. Results Weekly intravenous treatment with HGC-TAC significantly reduced genetically attributable lupus activity in lupus nephritis-positive mice. In addition, HGC-TAC treatment mitigated renal dysfunction, proteinuria, and histological injury, including glomerular proliferative lesions and tubulointerstitial infiltration. Furthermore, HGC-TAC treatment reduced renal inflammation and inflammatory gene expression and ameliorated increased apoptosis and glomerular fibrosis. Moreover, HGC-TAC administration regulated renal injury via the TGF-β1/MAPK/NF-κB signaling pathway. These renoprotective effects of HGC-TAC treatment were more potent in lupus mice compared to those of TAC treatment alone. Conclusion Our study indicates that weekly treatment with the HGC-TAC nanomicelles reduces kidney injury resulting from lupus nephritis by preventing inflammation, fibrosis, and apoptosis. This advantage of a new therapeutic modality using kidney-targeted HGC-TAC nanocarriers may improve drug adherence and provide treatment efficacy in lupus nephritis mice. ![]()

Abstract
Deferasirox (DFX) was formulated into oil-in-water microemulsions in the presence of pluronicto improve its oral bioavailability. The size of the DFX-loadedmicroemulsions system measured by dynamic light scattering (DLS) was about 9 nm. The anti-proliferative and anti-lipid peroxidation effects of DFX and DFX-loaded microemulsions were assessed on Human umbilical vein endothelial (HUVEC) cells. Our in vitro results showed that HUVEC cells are more susceptible to free DFX as compared to DFX-loaded microemulsions. Although both free and encapsulated DFX attenuated FeCl3-induced lipid peroxidation, after 6 and 12 h treatment, DFX-loaded microemulsions did not appear a better ameliorator than DFX. To compare the in vivo efficacy of free DFX and DFX-loaded microemulsions in iron- intoxicated rats, the animals were orally administered with 25 mg/kg DFX, or 25 mg/kg DFX microemulsions, respectively. In vivo gavage handling of free DFX significantly increased serum biochemical parameters. There was also a significant increase in lipid peroxidation in rats who received free DFX compared to those in the control rats. Treatment with DFX-loaded microemulsions restored the elevated levels of serum AST, ALT, and creatinine levels and also reduced liver MDA content. Histopathological analysis of renal and hepatic tissues was in line with the biochemical results. In conclusion, DFX-loaded microemulsions induce less toxicity than free DFX and appear a more desirable and safer drug carrier in combating the iron-overload complications. Theoretical simulations are performed to get better insight regarding interactions between DFX and surfactant F127.

Abstract
BACKGROUND Owing to the rich anticancer properties of flavonoids, there is a need for their incorporation into drug delivery vehicles like nanomicelles for safe delivery of the drug into the brain tumor microenvironment. OBJECTIVE This study, therefore, aimed to prepare the phospholipid-based Labrasol/Pluronic F68 modified nano micelles loaded with flavonoids (Nano-flavonoids) for the delivery of the drug to the target brain tumor. METHODS Myricetin, quercetin and fisetin were selected as the initial drugs to evaluate the biodistribution and acute toxicity of the drug delivery vehicles in rats with implanted C6 glioma tumors after oral administration, while the uptake, retention, release in human intestinal Caco-2 cells and the effect on the brain endothelial barrier were investigated in Human Brain Microvascular Endothelial Cells (HBMECs). RESULTS The results demonstrated that nano-flavonoids loaded with myricetin showed more evenly distributed targeting tissues and enhanced anti-tumor efficiency in vivo without significant cytotoxicity to Caco-2 cells and alteration in the Trans Epithelial Electric Resistance (TEER). There was no pathological evidence of renal, hepatic or other organs dysfunction after the administration of nanoflavonoids, which showed no significant influence on cytotoxicity to Caco-2 cells. CONCLUSION In conclusion, Labrasol/F68-NMs loaded with MYR and quercetin could enhance antiglioma effect in vitro and in vivo, which may be better tools for medical therapy, while the pharmacokinetics and pharmacodynamics of nano-flavonoids may ensure optimal therapeutic benefits.

Abstract
Strategies to take advantage of residual lignin from industrial processes are well regarded in the field of green chemistry and biotechnology. Quite recently, researchers transformed lignin into nanomaterials, such as nanoparticles, nanofibers, nanofilms, nanocapsules and nanotubes, attracting increasing attention from the scientific community. Lignin nanoparticles are seen as green way to use high-value renewable resources for application in different fields because recent studies have shown they are non-toxic in reasonable concentrations (both in vitro and in vivo assays), inexpensive (a waste generated in the biorefinery, for example, from the bioethanol platform) and potentially biodegradable (by fungi and bacteria in nature). Promising studies have tested lignin nanoparticles for antioxidants, UV-protectants, heavy metal absorption, antimicrobials, drugs carriers, gene delivery systems, encapsulation of molecules, biocatalysts, supercapacitors, tissue engineering, hybrid nanocomposites, wound dressing, and others. These nanoparticles can be produced from distinct lignin types and by different chemical/physical/biological methods, which will result in varied characteristics for their morphology, shape, size, yield and stability. Therefore, taking into account that the theme "lignin nanoparticles" is a trending topic, this present review is emerging and has the discuss the current status, covering from concepts, the formation mechanism, synthesis methods and applications, to the future perspectives and challenges linked to lignin-based nanomaterials, aiming at the viability and commercialization of this biotechnological product.

Abstract
To overcome the drawbacks of conventional delivery, this review spotlights a number of nanoscale drug delivery systems, including nanoparticles, liposomes, nano micelles, branched dendrimers, nanocapsules, and nanostructured lipid formulations for the targeted therapy of ovarian cancer. These nanoformulations offer numerous advantages to promote therapeutic drug delivery such as nontoxicity, biocompatibility, good biodegradability, increased therapeutic impact than free drugs, and non-inflammatory effects. Importantly, the development of specific ligands functionalized nanoformulations enable preferential targeting of ovarian tumors and eventually amplify the therapeutic potential compared to nonfunctionalized counterparts. Ovarian cancer is typically identified by biomarker assessment such as CA125, HE4, Mucin 1, and prostatic. There is, nevertheless, a tremendous demand for less costly, faster, and compact medical tools, both for timely detection and ovarian cancer control. This paper explored multiple types of tumor marker-based on nanomaterial biosensors. Initially, we mention different forms of ovarian cancer biomarkers involving CA125, human epididymis protein 4 (HE4), mucin 1 (MUC1), and prostate. It is accompanied by a brief description of new nanotechnology methods for diagnosis. Nanobiosensors for evaluating ovarian cancer biomarkers can be categorized based on electrochemical, optical, paper-based, giant magnetoresistive, and lab-on-a-chip devices.

Abstract
Periodontal diseases are worldwide chronic inflammatory conditions that are associated with heavy production of reactive oxygen species followed by damage of the tooth-supporting tissues. Although the mechanical approach of scaling and root planing (SRP) for removing of plaque is considered as the key element for controlling periodontitis, the anatomical complexity of the teeth hinders accessibility to deeper points. The aim of this study was to design a micellar nanocarrier of coenzyme Q10 (Q10) to support the management of moderate periodontitis. Q10 was formulated in nanomicelles (NMQ10) and evaluated regarding encapsulation efficiency, loading efficiency, percent yield, hydrodynamic size (Dh), polydispersity index (PDI), and zeta potential (ζ potential). NMQ10 was incorporated to in situ gelling systems and the in vitro release of Q10 was studied. A clinical study including evaluation of periodontal parameters and biochemical assay of total antioxidant capacity (T-AOC) and lipid peroxide was achieved. Results revealed that Q10 was efficiently entrapped in spherical-shaped stable NMQ10 with Dh, PDI, and ζ potential of 154.0 nm, 0.108, and - 31.67 mV, respectively. The clinical study revealed that SRP only exhibited improvement of the periodontal parameters. Also, assay of T-AOC and lipid peroxide revealed that their values diminished by 21.5 and 23.8%, respectively. On the other hand, SRP combined with local application of NMQ10 resulted in a significant management of the periodontal parameters, and likewise, the assayed biomarkers proved enhanced antioxidant activity over SRP alone. In conclusion, NMQ10 can be suggested as a promising nanosystem as an approach to support the management of chronic periodontitis. Such results could be used to conduct larger clinical studies.

Abstract
Lung cancer is one of the most common malignant tumors and emerged as one of the leading causes of cancer-related death worldwide. Surgical resection can be a curative treatment for early stage but the most of lung cancer patients are diagnosed at an advanced stage when the pulmonary tumor has been invaded beyond the respiratory system. Therefore, chemotherapy is suitable for curing metastasized tumor. Baicalin (BL) is a flavonoid which has been studied in the treatment of several types of cancer including lung cancer. However, its low solubility in water and non-specificity impede its practical utilization. Hence, we have reported a stearic acid and pluronic F68 conjugated nanomicelles (PF68-SA) system to improve therapeutic efficacy of BL. Solvent evaporation method was used to prepare the BL-loaded PF68-SA nanomicelles (BLNM). The designed BLNM were characterized for the particle size, surface charge, critical micelle concentration, colloidal stability, morphology, and total drug content. BLNM formulation showed improved toxicity of BL against A549 human lung cancer cells in cytotoxicity assay. Further, apoptosis study also depicted BLNM-induced cell death in A549 cells. Therefore, the synthesized fatty acid-modified polymeric nanomicellar system could be useful in overcoming the stability and low therapeutic efficacy issues of hydrophobic anticancer drugs like BL and delivering them to the cancer cells.

Abstract
Glioblastoma (GBM) is the most serious brain tumor and shows a high rate of drug resistance. Wnt signaling is a very important pathway in GBM that can activate/inhibit other pathways, such as apoptosis and autophagy. In this study, we evaluated the efficacy of a combination of temozolomide (TMZ) plus curcumin or nanomicellar-curcumin on the inhibition of GBM growth in vitro, via effects on autophagy, apoptosis, and the Wnt signaling pathway. Two concentrations of curcumin and nanomicellar-curcumin (i.e., 20 μM and 50 μM) alone, and in combination with TMZ (50 μM) were used to induce cytotoxicity in the U87 GBM cell line. Wnt signaling-, autophagy-, and apoptosis-related genes were assessed by quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) and Western blots. All treatments (except 20 μM curcumin alone) significantly decreased the viability of U87 cells compared to controls. Curcumin (50 μM), nanomicellar-curcumin alone and in combination with TMZ significantly decreased the invasion and migration of U87 cells. Autophagy-related proteins (Beclin 1, LC3-I, LC3-II) were significantly increased. Apoptosis-related proteins (Bcl-2 and caspase 8) were also significantly increased, while Bax protein was significantly decreased. The expression levels of Wnt pathway-associated genes (β-catenin, cyclin D1, Twist, and ZEB1) were significantly reduced.

Abstract
Preexposure prophylaxis (PrEP) using oral or vaginal microbicide is an emerging and effective strategy to prevent HIV transmission. Vaginal film is becoming more acceptable and a convenient dosage form compared to cream, gel and suppository. Extremely poor aqueous solubility of efavirenz (EFV) limits its use as vaginal microbicide. The aim of this study was to develop and evaluate a monomeric surfactant free, rapidly soluble vaginal film of EFV (EZ film). EZ film was prepared using a tetrafunctional block polymer (Tetronic 1107), carrageenan and polyvinyl alcohol (PVA) by solvent evaporation method. First, different solubilizers were screened for EFV solubility, in vitro cytotoxicity and cell membrane integrity assay on HeLa cells. Optimized film was characterized for solid state, mechanical strength, epithelial integrity, in vitro drug release in simulated vaginal fluid (SVF), simulated seminal fluid (SSF) and in vitro anti-HIV activity. Optimized EZ film showed a particle size of 48 ± 3.8 nm with PDI of 0.299. Differential scanning colorimetry (DSC) thermogram suggested the complete amorphization of EFV within the film. EZ film rapidly disintegrated (30 s) with complete release of EFV in SVF and SSF. The film was found to be non-toxic to HeLa cells and showed similar anti-HIV-1 activity as that of EFV in DMSO. EZ film did not show any significant change in the TEER value in HEC 1A cell line. Hence, the findings from the current study strongly suggest that the EZ film could be a cost-effective and convenient dosage form for PrEP of HIV.

Abstract
This study aimed to design the ideal nanonizing vehicle for poorly water-soluble model curcumin (CCM) using fattigation-platform nanotechnology, and to investigate the effects of fatty acid salts chain length on nanonizing CCM and its efficient delivery to different cancer cells. HSA-fatty acid conjugates were synthesized by EDC/NHS coupling. Fattigation-platform nanomicelles (NMs), prepared by film hydration, exhibited uniform and spherical morphology, although, each NM varied in particle size, zeta potential, and critical micelle concentration according to the types of fatty acid. Preliminary solubility studies of albumin conjugates with 5 types of fatty acid salts of different chain lengths revealed that C14 exhibited the highest solubilization of CCM. CCM-loaded HSA-C14 NMs demonstrated the highest drug content (5.35 ± 0.48%) and loading efficiency (95.93 ± 1.87%) compared to other NMs. It exhibited enhanced drug release rate and reduced micelle size in biorelevant dissolution medium. Interestingly, this solubilization approach was well applied in poorly water-soluble docetaxel trihydrate (DTX). Preliminary solubility results of DTX was also corresponded to the stable nanonization phenomenon in biorelevant dissolution medium. Compared to the CCM EtOH solution, HSA-C14 NMs showed higher internalization in cancer cell lines A549 and MCF-7, and consequently, exhibited significantly increased cytotoxicity against both cell lines. Therefore, this study provides a new solubilization approach for poorly water-soluble drugs using fatty acid salts of different chain lengths and their micellar formations via nanonization, which could be a promising tool for targeted cancer therapy using poorly water-soluble drugs.

Abstract
Hepatic fibrosis is one kind of liver diseases with a high mortality rate and incidence. The activation and proliferation of hepatic stellate cells (HSCs) is the most fundamental reason of hepatic fibrosis. There are no specific and effective drug delivery carriers for the treatment of hepatic fibrosis at present. We found that when hepatic fibrosis occurs, the expression of CD44 receptors on the surface of HSCs is significantly increased. Based on this finding, we designed silibinin-loaded hyaluronic acid (SLB-HA) micelles to achieve the treatment of hepatic fibrosis. Meanwhile, we constructed liver fibrosis rat model using Sprague–Dawley rats. We demonstrated that HA micelles had specific uptake to HSCs in vitro while avoiding the distribution in normal liver cells and the phagocytosis of macrophages. Importantly, HA micelles showed a significant liver targeting effect in vivo, especially in fibrotic liver which highly expressed CD44 receptors. In addition, SLB-HA micelles could selectively kill activated HSCs, having an excellent anti-hepatic fibrosis effect in vivo and a significant sustained release effect, and also had a good biological safety and biocompatibility. Overall, HA micelles represented a novel nanomicelle system which showed great potentiality in anti-hepatic fibrosis drugs delivery.

Abstract
Chemotherapeutic drugs frequently encounter multidrug resistance. ATP from mitochondria helps overexpression of drug efflux pumps to induce multidrug resistance, so mitochondrial delivery as a means of "repurposing'' chemotherapeutic drugs currently used in the clinic appears to be a worthwhile strategy to pursue for the development of new anti-drug-resistant cancer agents. TPP-Pluronic F127-hyaluronic acid (HA) (TPH), with a mitochondria-targeting triphenylphosphine (TPP) head group, was first synthesized through ester bond formation. Paclitaxel (PTX)-loaded TPH (TPH/PTX) nanomicelles exhibited excellent physical properties and significantly inhibited A549/ADR cells. After TPH/PTX nanomicelles entered acidic lysosomes through macropinocytosis, the positively charged TP/PTX nanomicelles that resulted from degradation of HA by hyaluronidase (HAase) in acidic lysosomes were exposed and completed lysosomal escape at 12 h, finally localizing to mitochondria over a period of 24 h in A549/ADR cells. Subsequently, TPH/PTX caused mitochondrial outer membrane permeabilization (MOMP) by inhibiting antiapoptotic Bcl-2, leading to cytochrome C release and activation of caspase-3 and caspase-9. In an A549/ADR xenograft tumor model and a drug-resistant breast cancer-bearing mouse model with lung metastasis, TPH/PTX nanomicelles exhibited obvious tumor targeting and significant antitumor efficacy. This work presents the potential of a single, nontoxic nanoparticle (NP) platform for mitochondria-targeted delivery of therapeutics for diverse drug-resistant cancers.

Abstract
Nanomaterials have been utilized for the drug delivery in the central nervous system (CNS), and many research investigators are currently focussing on this specified area. There has been a lot of advancement in the nanoparticle-mediated drug delivery to the brain. Neuronal injuries including spinal cord injury (SCI) and their targeted therapies are still in its infancy on this planet. SCI has been known to cause axonal damage followed by the loss of communication between CNS and other non-neuronal systems. SCI has been critically associated with prolonged inflammation, sensory dysfunction, and motor impairment in SCI patients. There has been a critical crosstalk in SCI and blood brain barriers (BBBs) for drug absorption and distribution in patients. There is a paucity of possible therapies for proper intervention of SCI due to selective permeability of the drugs across BBB. Nanomaterials are contemplated in the drug delivery system for SCI. In addition, self-assembled nanomicelles, lipid nanoparticles, and other co-polymers have now been explored for neuronal injuries. This review focuses on the promising approach and/or role of nanodrug delivery to target SCI in both in vitro and in vivo models.

Abstract
Although chemo-photodynamic therapy demonstrates promising synergetic therapeutic effect in malignant cancers, the currently available nanocarriers offer the limited capabilities for selective toxicity, drug release and tumor penetration. Herein, we developed photoactivatable nanomicelles, which are constructed by self-assembling of poly (ethylene glycol) (PEG)-stearamine (C18) conjugate (PTS) with a ROS-sensitive thioketal linker (TL) and co-loaded with doxorubicin (DOX) and photosensitizer pheophorbide A (PhA), for enhanced locoregional chemo-photodynamic therapy. Upon accumulation in tumor region, the resulting PTS nanomicelles loaded with Dox and PhA (PTS-DP) demonstrated reactive oxygen species (ROS) cascade responsive release of the DOX and PhA loaded inside. Initial intracellular release of DOX and PhA from the PTS-DP was triggered by the intrinsic presence of endogenous ROS within cancer cells. Furthermore, upon laser irradiation on the tumor region, enhanced singlet oxygen (1O2) was generated by PhA released initially in cancer cells, which in turns accelerated the cytoplasmic release of DOX through rapid dissociation of nanomicelles. The gradual elevation of local ROS level generated by light-activated PhA subsequent ROS-triggered release of DOX synergistically inhibited tumor growth and enhances the anti-tumor immunity. Findings of our study suggested that ROS-sensitive PTS nanomicelles could be a promising and innovative nanocarrier for locoregional chemo-photodynamic therapy.

Abstract
Although C6-Ceramide has attracted much attention as a possible tumor suppressor, the delivery of C6-Ceramide is still challenging due to its inherent hydrophobicity and insolubility. In this study we explored the use of a natural compound rubusoside (RUB) as a solubilizer to enhance the solubility of a fluorescence-labeled C6-Ceramide (NBD C6-Ceramide) and to characterize its pharmacokinetics and tissue distribution in an animal model. RUB significantly enhanced the solubility of NBD C6-Ceramide by forming nanomicelles, and efficiently delivered NBD C6-Ceramide in rats by oral and intravenous administration. RUB loaded 1.96 % of NBD C6-Ceramide in the nanomicelles and solubilized it to a concentration of 3.6 mg/mL in water. NBD C6-Ceramide in nanomicelles remained stable in aqueous solutions, allowing intravenous administration without the use of any organic solvents or surfactants. After oral administration, NBD C6-Ceramide rapidly rose to peak plasma concentrations within the first 90 min, distributed to tissues, and remained in vivo for more than 24 h. Tissular levels of NBD C6-Ceramide from high to low were associated with heart, lung, cerebellum, testicle, spleen, liver, kidney, and brain. Altogether, our study demonstrated that RUB-assisted nanomicelles can serve as an efficient and convenient delivery system for short-chain C6-Ceramide and enable in vivo evaluation of potential new cancer treatments.

Abstract
Here, a novel pH-responsive block copolymer, poly (ethylene glycol)-poly(ε-caprolactone)-poly(L-histidine) (PEG-PCL-PHis), was synthesized and designed for anti-cancer drug delivery with excellent biocompatible, biodegradable, and strong drug loading efficiency. 1H-NMR, IF-IR, and GPC were used to characterize the structure of the PEG-PCL-PHis copolymer. In addition, the morphology, particle size, Zeta potential, and critical micelle concentration (CMC) of different degree of polymerization were determined by transmission electron microscopy (TEM), dynamic light scattering granulometer (DLS), and fluorescence spectrometer, respectively. The strong affinity between the core of micelles and hydrophobic drug was manifested with 15.09% drug loading content and 84.65% entrapment efficiency. In vitro release of DOX from the block copolymer micelle demonstrated, the PEG-PCL-PHis copolymer micelle has stable and durable drug releasing ability accompanied with pH-sensitivity. From the mechanism of cellular uptake the micelles, the pathway of drug release was captured by confocal laser scanning microscope. These experiments demonstrated the safe delivery for anticancer medicine through this novel copolymer. In conclusion, the PEG-PCL-PHis copolymer micelle has great potential to become a safe drug carrier for cancer chemotherapy.

Abstract
Antibiotics are powerful weapons to fight against bacterial infections, while most of them lack of selective targeting towards pathological site which could restrict their antibacterial efficacy. To overcome this challenge, an antimicrobial levofloxacin(LF)was conjugated onto hyaluronic acid (HA) moieties via an o-phenylenediamine linker to prepare a NO-sensitive nanosystem (HA-NO-LF) in this study. The HA-NO-LF nanomicelles could enter host cells via a CD44 mediated endocytosis and release drug gradually upon exposure to endogenous NO. Furthermore, the more promising therapeutic effect of the nanomicelles in ameliorating inflammatory levels was observed in a mouse pneumonia model than that of LF. These results suggest that the HA-NO-LF nanomicelles may exert potent curative effect in infectious diseases.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy of pyrimethamine-loaded poloxamer 407 nanomicelles on Plasmodium berghei strain NICD in vivo. METHODS Pyrimethamine-loaded nanomicelles were prepared and their zeta potential, particle size and polydispersity index were measured. For antiplasmodial assessment, 54 mice were randomly divided into six groups. Four groups were infected intraperitoneally with P. berghei, whereas the two remaining groups did not receive the parasite (negative controls). Three of the P. berghei-infected groups received treatment with either pyrimethamine-loaded nanomicelles (2 mg/kg), pyrimethamine (2 mg/kg) or empty nanomicelles (2 mg/kg); the fourth group remained untreated (positive control). The parasitaemia rate, survival rate and histopathological changes in the liver, spleen and kidneys were examined and were compared with the negative and positive control groups. RESULTS The mean parasitaemia rate differed significantly between the nanoformulated pyrimethamine group and each of the other groups (P<0.05). Moreover, the survival rate of mice in the nanoformulated pyrimethamine group (7/9; 78%) was significantly higher compared with each of the other groups (P<0.01). The main histopathological changes, including hepatic necrosis in the liver, lymphoid hypoplasia in the spleen, and tubular nephrosis and perivascular and interstitial lymphocytic infiltration in the kidneys, were considerably lower in the nanoformulated pyrimethamine group than in the pyrimethamine and positive control groups. CONCLUSION Pyrimethamine-loaded nanomicelles showed potent antimalarial activity and can be considered as a potential candidate for further examination of their suitability as an antimalarial drug.

Abstract
Almost all functions of cells or organs rely on the activities of cellular enzymes. Indeed, the in-vivo activities that directly represent the cellular effects of enzymes in live organs are critical importance to appreciate the roles enzymes play in modulating physiological or pathological processes, although assessments of such in-vivo enzyme activity are more difficult than typical test-tube assays. Recently, we, for the first time, developed a direct and easy-handling method for HPLC analyzing the in-vivo activity of glucosylceramide synthase (GCS). GCS that converts ceramide into glucosylceramide is a limiting-enzyme in the syntheses of glycosphingolipids and is one cause of cancer drug resistance. In our method developed, rubusoside nanomicelles delivers fluorescence N-[6-[(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]hexanoyl]-d-erythro-sphingosine (NBD C6-ceramide) into mice, tissues uptake the cell-permeable substrate, and GCS converts it into NBD C6-glucosylceramide in all organs simultaneously. Further, HPLC analyzes the extracted NBD C6-glucosylceramide to assess alterations of the in-vivo GCS activities in tissues. This method can be broadly used to assess the in-vivo GCS activities in any kind of animal models to appreciate either the role GCS plays in diseases or the therapeutic efficacies of GCS inhibitors.

Abstract
INTRODUCTION Polymeric micelles represent nowadays an interesting formulative approach for ocular drug delivery, as they act as solubility enhancers of poorly soluble drugs and promote drug transport across cornea and sclera. In particular, in the last 5 years polymeric nanomicelles have been increasingly investigated to overcome some of the important challenges of the topical treatment of ocular diseases. AREAS COVERED The aim of this review was to gather up-to-date information on the different roles that polymeric micelles (commonly in the nanosize scale) can play in ocular delivery. Thus, after a general description of ocular barriers and micelles features, the attention is focused on those properties that are relevant for ophthalmic application. Finally, their efficacy in improving the ocular delivery of different classes of therapeutics (anti-inflammatory, immunosuppressant, antiglaucoma, antifungal, and antiviral drugs) are reported. EXPERT OPINION Although still a few, in vivo experiments have clearly demonstrated the capability of polymeric nanomicelles to overcome a variety of hurdles associated to ocular therapy, notably increasing drug bioavailability. However, there are still some very important issues to be solved, such as tolerability and stability; additionally, the role of micelles in drug uptake by the ocular tissues and their potential for the treatment of posterior eye diseases still need to be clarified/verified.

Abstract
Conventional chemotherapy suffers lack of bioavailability, selectivity and multidrug resistance (MDR). Nano-sized drug delivery systems (DDS) is developing aimed to solve several limitations of conventional drug delivery systems. These systems have been offered for targeting tumor tissue due to their long circulation time and improved drug solubility, retention (EPR) effect, and enhanced permeability. So, the aim of this research was the development and design of a novel targeted nanocarrier for cancer chemotherapy. For this reason, chitosan (CS) was first modified with a chain transfer agent (CTA) to create CS-CTA macroinitiator. Then, the controlled grafting polymerization of itaconic acid (IA) and dimethylaminoethyl methacrylate quaternary ammonium alkyl halide (DMAEMAQ) monomers were occurred using reversible addition-fragmentation chain transfer (RAFT) polymerization to generate CS-g-(PIA-co-PDMAEMAQ) nanomicelles. To follow the cancer cells, fluorescein dye was entrapped into the core of nanomicelles and methotrexate (MTX) anticancer drug as a target ligand was incorporated into the cationic segment of nanomicelles. The chemical structures, biocompatibility, MTX loading capacity, in-vitro cytotoxicity effects and drug targeting ability of the developed nanomicelles were also investigated. Finally, it is expected that the nanomicelles can be used as a novel platform for targeted delivery.

Abstract
Morin hydrate (MH) is a naturally occurring polyphenolic flavonol compound. It has been recently investigated for its many biological activities such as anti-inflammatory, anticancer, antioxidant, antiarthritic, antifertility, antiplasmodic and anticancer. Though these outcomes are very promising, its low aqueous solubility and oral bioavailability restrict its clinical uses. Therefore, in this study we report pluronic F68 and stearic acid conjugated (F68-SA) nanomicelles for increasing oral bioavailability of MH. The MH loaded F68-SA nanomicelles (MHNM) were prepared by the solvent evaporation method. The MHNM were extensively characterized for the size, surface charge, stability, morphology, critical micelle concentration, drug content, and in-vitro drug release. The cell viability assay depicted a significant increase in cytotoxicity of MH against A549 human lung cancer cells after incubating as MHNM. Exposure of A549 cells to MHNM induced cell apoptosis in the cells as observed in apoptosis studies. Pharmacokinetic studies in Sprague-Dawley rats revealed that MHNM significantly increased the oral bioavailability of MH as compared to pure drug. Therefore, the novel, surfactant-lipid based micellar system is an effective solubilizing and delivering system for oral administration of poorly water soluble drugs like MH.

Abstract
Peritoneal carcinomatosis (PC) is a fatal condition arising in the gastrointestinal tract. PC patients administered drugs locally in the tumor region, such as in intraperitoneal chemotherapy (IPCh), suffer from low drug retention time and tumor penetration. Herein, we synthesized a lithocholic acid (LCA)-conjugated disulfide-linked polyethyleneimine (ssPEI) micelle (LAPMi) nanoconstruct by covalently conjugating ssPEI and LCA, thereby forming positive charged nanomicellar structures loaded with paclitaxel (PTX) (LAPMi-PTX) for IPCh. The incorporation of a positive surface charge aided in prolonging the peritoneal retention time, presumably via ascites-induced protein corona formation, and the subsequent size expansion caused resistance against undesired clearance through lymphatic openings. Furthermore, preferential tumor penetration by LAPMi-PTX is attributable to the permeation-enhancing properties of LCA, and the subsequent tumor activatable drug release was induced by the presence of disulfide linkages. By integrating these properties, LAPMi exhibited prolonged peritoneal residence time, enhanced tumor permeation and chemotherapeutic effect evidenced by in vitro, tumor spheroid and in vivo studies. Importantly, our strategy enabled significant PC inhibition and increased the overall survival rate of tumor-bearing mice. In conclusion, we provided a new paradigm of intractable PC treatment by enabling the prolonged residence time of the nanoconstruct, thereby enhancing tumor penetration and anti-tumor therapy.

Abstract
Background Chemotherapeutic drugs used for cancer therapy frequently encounter multiple-drug resistance (MDR). Nanoscale carriers that can target tumors to accumulate and release drugs intracellularly have the greatest potential for overcoming MDR. Glucose transporter-1 (GLUT-1) and glutathione (GSH) overexpression in cancer cells was exploited to assemble aminoglucose (AG)-conjugated, redox-responsive nanomicelles from a single disulfide bond-bridged block polymer of polyethylene glycol and polylactic acid (AG-PEG-SS-PLA). However, whether this dual functional vector can overcome MDR in lung cancer is unknown. Results In this experiment, AG-PEG-SS-PLA was synthetized successfully, and paclitaxel (PTX)-loaded AG-PEG-SS-PLA (AG-PEG-SS-PLA/PTX) nanomicelles exhibited excellent physical properties. These nanomicelles show enhanced tumor targeting as well as drug accumulation and retention in MDR cancer cells. Caveolin-dependent endocytosis is mainly responsible for nanomicelle internalization. After internalization, the disulfide bond of AG-PEG-SS-PLA is cleaved in the presence of high intracellular glutathione levels, causing the hydrophobic core to become a polar aqueous solution, which subsequently results in nanomicelle disassembly and the rapid release of encapsulated PTX. Reduced drug resistance was observed in cancer cells in vitro. The caspase-9 and caspase-3 cascade was activated by the AG-PEG-SS-PLA/PTX nanomicelles through upregulation of the pro-apoptotic proteins Bax and Bid and suppression of the anti-apoptotic protein Bcl-2, thereby increasing apoptosis. Furthermore, significantly enhanced tumor growth inhibition was observed in nude mice bearing A549/ADR xenograft tumors after the administration of AG-PEG-SS-PLA/PTX nanomicelles via tail injection. Conclusions These promising results indicate that AG-PEG-SS-PLA/PTX nanomicelles could provide the foundation for a paradigm shift in MDR cancer therapy.

Abstract
Background Lung cancer stem cells (CSCs) are considered to be the seed of lung cancer, and CD133 is a marker of lung CSCs. Here, we developed gefitinib-loaded poly(ethylene glycol) 2000-distearoylphosphatidylethanolamine nanomicelles with CD133 aptamers (M-Gef-CD133) to eliminate CD133+ lung CSCs. Methods M-Gef-CD133 was prepared using a lipid-film-based approach. The targeting and activity of M-Gef-CD133 towards lung CSCs were evaluated. Results M-Gef-CD133 were small (25 nm) and showed enhanced cytotoxic effect towards CD133+ lung CSCs compared with non-targeted M-Gef and gefitinib. Notably, M-Gef-CD133 could significantly reduce tumor sphere formation and the percentage of CD133+ lung CSCs, indicating that it possesses selective toxicity against CD133+ lung CSCs. Conclusions The interaction of CD133 aptamers and CD133 shows promise in the delivery of gefitinib to CD133+ lung CSCs, and M-Gef-CD133 represents a promising treatment to target lung CSCs.

Abstract
Metastatic cancer is responsible for 90% of deaths in world. Usage of nano-carriers improve the delivery and efficacy of chemotherapeutic agents. Recent studies suggest that decoration of the surface of nano-carriers with various targeting agents may further improve their overall therapeutic efficacy. Using specified peptides in targeted drug delivery is a key point in recent researches. In this study, tumor metastasis targeting (TMT) homing peptide was applied as a targeting group to improve specific drug delivery to tumor cells. TMT peptide is conjugated to poly ethylene glycol-poly caprolactone (PEG-PCL) micellar nanoparticles as carriers for targeted delivery of cabazitaxel to metastatic breast cancer cells. Synthesis of PEG-PCL copolymer was performed by amidation reaction between carboxylic acid group of PEG and amine group of PCL. Nanomicelles were prepared via solvent evaporation method. TMT peptide was covalently conjugated onto nanomicelles through the amine group of PEG. TMT-PEG-PCL nanoparticles were analyzed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), dynamic light scattering (DLS), gel permeation chromatography (GPC) and nuclear magnetic resonance (NMR). Toxicity and cellular uptake of nanomicelles were investigated by in vitro cytotoxicity assays and confocal scanning microscopy in MCF-7 (non-metastatic breast cancer cells) and MDA-MB-231 (metastatic breast cancer cells). The final nanomicelles had about 110nm mean size and encapsulation efficiency of 82.5%. Treatment of metastatic breast cancer cells with targeted nanomicelles significantly increased the necrosis rate to 65%, compared to 33% in non-targeted nanomicelles and 8% in control group. The MDA-MB-231 cells treated with targeted nanomicelles exhibited a strong increase in the fluorescence intensity of coumarin in comparison to the cells treated with non-targeted nanomicelles (p<0.001). It could be concluded that the present carrier has the potential to be considered in treatment of metastatic breast cancer cells.

Abstract
In this study, poly(ethylene-co-vinyl alcohol) (EVOH) as a novel biocompatible polymeric scaffold was surface modified by succinylation to get EVOHS and further pegylated to improve structural properties using methoxypolyethylene glycol (5000 Da) succinate (PEGS) along with targeting with retinoic acid (RA) to get final modified active and passive targeted conjugate (PEGS-EVOHS-RA) to evaluate its ability in carrying and delivery of epirubicin to hepatocellular carcinoma cell lines in response to varying temperatures. In this regard, the PEGS-EVOHS-RA conjugate was prepared through the desired chemical reactions and its structure was confirmed using 1H-NMR and FT-IR spectra. The micelles were prepared from PEGS-EVOHS-RA by dialysis method. The Particle size and zeta potential were measured, and entrapment efficacy along with in vitro release efficiency in different temperatures were also studied. The structural morphology of optimized nanomicelle was studied by transmission electron microscopy micrographs. The desired final micelles were evaluated for their toxicity using MTT assay on HepG2 human hepatocellular carcinoma cell lines at normal (37 °C) and elevated temperature (45 °C). The results revealed that, as the hydrophilicity of micelles increased, all characteristic properties improved. Then, these micelles can be considered as potentially effective thermo responsive delivery systems for targeted delivery of cytotoxic agents to hepatocellular carcinoma.

Abstract
INTRODUCTION In recent years, nanomedicines have raised as a powerful tool to improve prevention, diagnosis and treatment of different pathologies. Among the most well investigated biomaterials, D-α-tocopheryl polyethylene glycol succinate (also known as TPGS) has been on the spot for the last decade. We therefore designed a method to biologically characterize TPGS-based nanomicelles by labeling them with 99mTc. METHODS Labeling process was performed by a direct method. The average hydrodynamic diameter of TPGS nanomicelles was measured by dynamic light scattering and radiochemical purity was assessed by thin layer chromatography. Imaging: a dynamic study was performed during the first hour post radioactive micelles administration in a gamma camera (TcO4- was also administered for comparative purposes). Then two static images were acquired in ventral position: 1h and 12h post injection. Blood pharmacokinetics of 99mTc-TPGS during 24h was performed. RESULTS Images revealed whole body biodistribution at an early and delayed time and semiquantification was performed in organs of interest (%Total counts: soft tissue 6.1±0.5; 3.9±0.1, Bone 1.2±0.2; 1±0.1, Heart 1.5±0.6; 0.7±0.3, Kidneys 16.6±1.3; 26.5±1.7, Liver 8.6±1.1; 11.1±0.1 for 1 and 12 h post injection respectively). CONCLUSION This work demonstrated that TPGS based nanomicelles are susceptible to be radiolabeled with 99mTc thus they can be used to perform imaging studies in animal models. Moreover radiolabeling of these delivery nano systems reveals their possibility to be used as diagnostic agents in the near future.

Abstract
To improve its poor aqueous solubility and stability, the potential chemopreventive agent quercetin was encapsulated in freeze-dried polymeric micelles by a thin film hydration and vacuum freeze-drying process before being used for glioma chemotherapy. The micelle characteristics, release profile, cellular uptake, intracellular drug concentration, transport across the blood-brain barrier, and antitumor efficiency in vivo were investigated. Results showed that the particle size of quercetin-loaded freeze-dried nanomicelles (QUE-FD-NMs) ranged from 20 to 80nm, with an efficiently sustained release profile. Increased intracellular uptake into Caco-2 cells with low cytotoxicity, efficient penetration of BBB, and powerful cytotoxicity on C6 glioma cells were observed. QUE-FD-NMs accumulated in tumor-bearing brain tissues and exhibited significant antitumor effects in vivo, which significantly benefited the survival of glioma-bearing mice. These findings suggest that freeze-drying micelles loaded with quercetin is a promising drug delivery method for glioma therapy.
