Abstract
Background: A requirement for nanoparticle (NP) research is visualization of particles within cells and tissues. Limitations of electron microscopy and low yields of NP fluorescent tagging warrant the identification of alternative imaging techniques. Method: Confocal reflectance microscopy (CRM) in combination with fluorescence imaging was assessed for visualizing rhodamine B-conjugated silver and fluorescein isothiocyanate-conjugated lipid core-stearylamine NP uptake in vitro and in vivo. Results: CRM successfully identified cellular uptake and blood-brain barrier penetration of NPs owing to their distinguishing refractive indices. NP-dependent reflectance signals in vitro were dose and incubation time dependent. Finally, CRM facilitated the distinction between nonspecific fluorescence signals and NPs. Conclusion: These findings demonstrate the value of CRM for NP visualization in tissues, which can be performed with a standard confocal microscope.

Abstract
Central nervous system (CNS) diseases are the leading causes of death and disabilities in the world. It is quite challenging to treat CNS diseases efficiently because of the blood-brain barrier (BBB). It is a physical barrier with tight junction proteins and high selectivity to limit the substance transportation between the blood and neural tissues. Thus, it is important to understand BBB transport mechanisms for developing novel drug carriers to overcome the BBB. This paper introduces the structure of the BBB and its physiological transport mechanisms. Meanwhile, different strategies for crossing the BBB by using nanomaterial-based drug carriers are reviewed, including carrier-mediated, adsorptive-mediated, and receptor-mediated transcytosis. Since the viral-induced CNS diseases are associated with BBB breakdown, various neurotropic viruses and their mechanisms on BBB disruption are reviewed and discussed, which are considered as an alternative solution to overcome the BBB. Therefore, most recent studies on virus-mimicking nanocarriers for drug delivery to cross the BBB are also reviewed and discussed. On the other hand, the routes of administration of drug-loaded nanocarriers to the CNS have been reviewed. In sum, this paper reviews and discusses various strategies and routes of nano-formulated drug delivery systems across the BBB to the brain, which will contribute to the advanced diagnosis and treatment of CNS diseases.

Abstract
By virtue of their small size, nanomaterials can cross the blood-brain barrier and, when modified to target specific cells or regions, can achieve high bioavailability at the intended site of action. Modified nanomaterials are therefore promising agents for the diagnosis and treatment of neurodegenerative diseases such as Alzheimer's disease (AD). Here we review the roles and mechanisms of action of nanomaterials in AD. First, we discuss the general characteristics of nanomaterials and their application to nanomedicine. Then, we summarize recent studies on the diagnosis and treatment of AD using modified nanomaterials. These studies indicate that using nanomaterials is a potential strategy for AD treatment by slowing the progression of AD through enhanced therapeutic effects.

Abstract
Beta-carotene (BC), a red-colored pigment found in plants and animals, is one of the most extensively investigated carotenoids due to its provitamin-A, antioxidant, and anticancer properties. The anticancer activity of BC through oral administration is severely affected due to its low bioavailability and oxidative degradation. The present study aimed to formulate and characterize solid lipid nanoparticles (SLNs) of BC for enhanced bioavailability and therapeutic efficacy. Beta-carotene-loaded solid lipid nanoparticles (BC-SLNs) were prepared employing different combinations of glyceryl monostearate and gelucire. The characterization studies were performed for particle size, morphology, release behavior, and stability. BC-SLNs were also studied for in vitro cytotoxicity in human breast cancer cell lines (MCF-7) and pharmacokinetic studies in Wistar rats. The cytotoxicity studies confirmed that encapsulation of BC within the lipid bilayers of nanoparticles did not affect its anticancer efficacy. An improved anticancer activity was observed in BC-SLNs as compared to the free BC. BC-SLNs enhanced the bioavailability of BC on oral administration by sustaining its release from the lipid core and prolongation of circulation time in the body. Similarly, area under the curve (AUCtotal) enhanced 1.92-times more when BC was incorporated into SLNs as compared to free BC. In conclusion, solid lipid nanoparticles could be an effective and promising strategy to improve the biopharmaceutical properties of carotenoids for anticancer effects.

Abstract
Beta carotene (βC) loaded nanoparticles of zein (βC-NPs) were developed using modified phase separation technique. βC-NPs were prepared using different zein concentration and optimized formulation was selected on the basis of micromeritics properties and entrapment efficiency. Further, βC-NPs were evaluated for in vitro release, in vitro cell-survival, cellular localization and apoptosis induced in MCF-7 cells. The combined effect of the βC and its nanoparticulate counterpart with MTX was evaluated thereafter for cytotoxicity and apoptotic activity in MCF-7 cells. In comparison to free βC, the βC-NPs demonstrated noteworthy improvement in various biopharmaceutical attributes viz Cmax (∼2.3-folds), AUCtotal (2.7-folds), t1/2 (∼1.5 folds) and MRT (∼1.5 folds), further indicating the remarkable increment in oral bioavailability of βC after incorporation in zein nanoparticles. The anti-tumour potential of prepared βC-NPs and effects of free βC and βC-NPs were investigated upon anticancer efficacy of methotrexate (MTX) in experimentally induced breast cancer rat model. Protective role of βC on MTX-associated hepatic toxicity in wistar rats was also determined using haematological and histopathological approaches. In a nutshell, zein nanoparticles improved the cellular uptake, cytotoxicity and exhibited enhanced oral biopharmaceutical performance of βC. This combination regimen could also be promising platform to facilitate the therapeutic benefits of anticancer agents.

Abstract
The practical use of solid lipid nanoparticles (SLNs) in research has been highlighted in the literature, but few reports have combined SLNs with miRNA-based therapy and chemotherapy. We aimed to prepare cationic SLNs (cSLNs) to load anti-miR-21 oligonucleotide and pemetrexed for glioblastoma therapy in vitro. cSLNs were employed to encapsulate both pemetrexed and anti-miR-21 by a high-pressure homogenization method, and then the properties of cSLNs were characterized. We studied cellular uptake and cytotoxicity properties of cSLNs in U87MG cells. cSLNs were 124.9 ± 1.6 nm in size and 27.3 ± 1.6 mV in zeta potential with spherical morphology in the TEM image. cSLNs uptake by U87MG cells was increased significantly higher and more effective than free pemetrexed. These findings suggest that cSLNs represent a potential new approach for carrying both pemetrexed and anti-miR-21 for glioblastoma therapy.

Abstract
Aim: This work was intended to investigate the targeting potential of fructose-tethered lipid-polymeric hybrid nanoparticles (F-BC-MTX-LPHNPs) co-loaded with beta carotene (BC) and methotrexate (MTX) in breast cancer therapeutics and find out the possible protective role of BC on MTX-induced toxicity. Materials & methods: F-BC-MTX-LPHNPs were fabricated using self-assembled nano-precipitation technique. Fructose was conjugated on the surface of the particles. The in vitro cytotoxicity, sub-cellular localization and apoptotic activity of F-BC-MTX-LPHNPs were evaluated against MCF-7 breast cancer cells. The antitumor potential of F-BC-MTX-LPHNPs was further studied. Results & conclusion: Outcomes suggested that F-BC-MTX-LPHNPs induced the highest apoptosis index (0.89) against MCF-7 cells. Following 30 days of treatment, the residual tumor progression was assessed to be approximately 32%, in animals treated with F-BC-MTX-LPHNPs. F-BC-MTX-LPHNPs are competent to selectively convey the chemotherapeutic agent to the breast cancers. Beta carotene ameliorated MTX-induced hepatic and renal toxicity.

Abstract
New drug delivery systems are highly needed in research and clinical area to effectively treat gliomas by reaching a high antineoplastic drug concentration at the target site without damaging healthy tissues. Intranasal (IN) administration, an alternative route for non-invasive drug delivery to the brain, bypasses the blood-brain-barrier (BBB) and eliminates systemic side effects. This study evaluated the antitumor efficacy of farnesylthiosalicylic acid (FTA) loaded (lipid-cationic) lipid-PEG-PLGA hybrid nanoparticles (HNPs) after IN application in rats. FTA loaded HNPs were prepared, characterized and evaluated for cytotoxicity. Rat glioma 2 (RG2) cells were implanted unilaterally into the right striatum of female Wistar rats. 10days later, glioma bearing rats received either no treatment, or 5 repeated doses of 500μM freshly prepared FTA loaded HNPs via IN or intravenous (IV) application. Pre-treatment and post-treatment tumor sizes were determined with MRI. After a treatment period of 5days, IN applied FTA loaded HNPs achieved a significant decrease of 55.7% in tumor area, equal to IV applied FTA loaded HNPs. Herewith, we showed the potential utility of IN application of FTA loaded HNPs as a non-invasive approach in glioblastoma treatment.

Abstract
The present study was aimed to coencapsulate methotrexate (MTX) and aceclofenac (ACL) in fucose anchored lipid-polymer hybrid nanoparticles (Fu-LPHNPs) to achieve target specific and controlled delivery for developing therapeutic interventions against breast cancer. The effective combination therapy requires coadministration of drugs to achieve synergistic effect on tumor with minimum adverse effects. Present study investigates the potential of codelivery of MTX and ACL through LPHNPs in MCF-7 and triple negative breast cancer cells (MDA-MB-231). We obtained LPHNPs in the nanosize range (<150 nm) with better particle size distribution (<0.3). The entrapment and loading efficiency of MTX and ACL was calculated as 85-90% and 10-12%, respectively. The coumarin-6 LPHNP formulations showed rapid internalization within 2 h incubation with MCF-7 and MDA-MB-231 cells. With 8-10 times, greater bioavailability of drug-loaded LPHNPs than free MTX and ACL was obtained. Also, antitumor efficacy of MTX- and ACL-loaded LPHNPs was determined on DMBA-induced experimental breast cancer mouse model. This model showed better control over tumor growth with MTX- and ACL-loaded LPHNPs than the combination of MTX and ACL or MTX alone. ACL-loaded LPHNPs showed prophylactic and anticancer activity in DMBA-induced mouse model at higher dose (10 mg/kg). ACL-LPHNPs confer synergistic anticancer effect when administered in combination with MTX. In conclusion, ACL enhances the therapeutic and anticancer efficacy of MTX, when coencapsulated into fucose-anchored LPHNPs, as confirmed by cell viability and serum angiogenesis (IL-6, TNF-α, IL-1β, COX2, and MMP1) at both transcript and proteome level.

Abstract
OBJECTIVES We aimed to develop lipid-polyethylene glycol (PEG)-polymer hybrid nanoparticles, which have high affinity to tumour tissue with active ingredient, a new generation antineoplastic drug, farnesylthiosalicylic acid (FTA) for treatment of glioblastoma. METHOD Farnesylthiosalicylic acid-loaded poly(lactic-co-glycolic acid)-1,2 distearoyl-glycerol-3-phospho-ethanolamine-N [methoxy (PEG)-2000] ammonium salt (PLGA-DSPE-PEG) with or without 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) hybrid nanoparticles has been prepared and evaluated for in-vitro characterization. Cytotoxicity of FTA-loaded nanoparticles along with its efficacy on rat glioma-2 (RG2) cells was also evaluated both in vitro (in comparison with non-malignant cell line, L929) and in vivo. KEY FINDINGS Scanning electron microscopy studies showed that all formulations prepared had smooth surface and spherical in shape. FTA and FTA-loaded nanoparticles have cytotoxic activity against RG2 glioma cell lines in cell culture studies, which further increases with addition of DOTAP. Magnetic resonance imaging and histopathologic evaluation on RG2 tumour cells in rat glioma model (49 female Wistar rats, 250-300 g) comparing intravenous and intratumoral injections of the drug have been performed and FTA-loaded nanoparticles reduced tumour size significantly in in-vivo studies, with higher efficiency of intratumoral administration than intravenous route. CONCLUSION Farnesylthiosalicylic acid-loaded PLGA-DSPE-PEG-DOTAP hybrid nanoparticles are proven to be effective against glioblastoma in both in-vitro and in-vivo experiments.

Abstract
CNS disorders are on the rise despite advancements in our understanding of their pathophysiological mechanisms. A major hurdle to the treatment of these disorders is the blood-brain barrier (BBB), which serves as an arduous janitor to protect the brain. Many drugs are being discovered for CNS disorders, which, however fail to enter the market because of their inability to cross the BBB. This is a pronounced challenge for the pharmaceutical fraternity. Hence, in addition to the discovery of novel entities and drug candidates, scientists are also developing new formulations of existing drugs for brain targeting. Several approaches have been investigated to allow therapeutics to cross the BBB. As the molecular structure of the BBB is better elucidated, several key approaches for brain targeting include physiological transport mechanisms such as adsorptive-mediated transcytosis, inhibition of active efflux pumps, receptor-mediated transport, cell-mediated endocytosis, and the use of peptide vectors. Drug-delivery approaches comprise delivery from microspheres, biodegradable wafers, and colloidal drug-carrier systems (e.g., liposomes, nanoparticles, nanogels, dendrimers, micelles, nanoemulsions, polymersomes, exosomes, and quantum dots). The current review discusses the latest advancements in these approaches, with a major focus on articles published in 2015 and 2016. In addition, we also cover the alternative delivery routes, such as intranasal and convection-enhanced diffusion methods, and disruption of the BBB for brain targeting.

Abstract
The present study is designed to engineer fucose anchored methotrexate loaded solid lipid nanoparticles (SLNs) to target breast cancer. The developed nano-carriers were characterized with respect to particle size, PDI, zeta potential, drug loading and entrapment, in-vitro release etc. The characterized formulations were used to comparatively assess cellular uptake, cell-viability, apoptosis, lysosomal membrane permeability, bioavailability, biodistribution, changes in tumor volume and animal survival. The ex-vivo results showed greater cellular uptake and better cytotoxicity at lower IC50 of methotrexate in breast cancer cells. Further, we observed increased programmed cell death (apoptosis) with altered lysosomal membrane permeability and better rate of degradation of lysosomal membrane in-vitro. On the other hand, in-vivo evaluation showed maximum bioavailability and tumor targeting efficiency with minimum secondary drug distribution in various organs with formulated and anchored nano-carrier when compared with free drug. Moreover, sizeable reduction in tumor burden was estimated with fucose decorated SLNs as compared to that seen with free MTX and SLNs-MTX. Fucose decorated SLNs showed promising results to develop therapeutic interventions for breast cancer, and paved a way to explore this promising and novel nano-carrier which enables to address breast cancer.

Abstract
The present study was designed to engineer surface-anchored and methotrexate loaded lipobrid nano-constructs for targeting breast cancer. Ligands (fucose, galactose and mannose) anchored lipobrid nano-constructs were used to compare and assess delivery efficiency in breast cancer cell lines as well as in DMBA induced breast cancer animal model. The developed and characterized formulations were used to comparatively assess cellular uptake, cell-viability, apoptosis, lysosomal membrane permeability, bioavailability, bio-distribution, changes in tumor volume and animal survival. Our results show greater cellular uptake, cytotoxicity at low IC50, apoptosis with altered lysosomal membrane permeability and greater rate of degradation of lysosomal membrane. We saw better bioavailability and tumor targeting efficiency with minimum secondary organ drug distribution. The significant reduction was seen in tumor burden with ligand anchored lipobrids in comparison to plain and MTX-lipobrid formulations. In conclusion, fucose anchored MTX-lipobrid formulation showed promising results, and warrants to explore the development of therapeutic interventions for breast cancer.

Abstract
The present investigation reports the preparation, optimization, and characterization of surface engineered solid lipid nanoparticles (SLNs) encapsulated with doxorubicin (DOX). Salient features such as biocompatibility, controlled release, target competency, potential of penetration, improved physical stability, low cost and ease of scaling-up make SLNs viable alternative to liposomes for effective drug delivery. Galactosylation of SLNs instructs some gratifying characteristic, which leads to the evolution of promising delivery vehicles. The impendence of lectin receptors on different cell surfaces makes the galactosylated carriers admirable for targeted delivery of drugs to ameliorate their therapeutic index. Active participation of some lectin receptors in immune responses to antigen overlaid the application of galactosylated carriers in delivery of antigen and immunotherapy for treatment of maladies like cancer. These advantages revealed the promising potential of galactosylated carriers in each perspective of drug delivery. The developed DOX loaded galactosylated SLNs formulation was found to have particle size 239 ± 2.40 nm, PDI 0.307 ± 0.004, entrapment efficiency 72.3 ± 0.9%. Higher cellular uptake, cytotoxicity, and nuclear localization of galactosylated SLNs against A549 cells revealed higher efficiency of the formulation. In a nutshell, the galactosylation strategy with SLNs could be a promising approach in improving the delivery of DOX for cancer therapy.

Abstract
PURPOSE The debut study was aimed to develop Lactic acid (LA)-conjugated solid lipid nanoparticles (SLN-LA) bearing albendazole (ALB) and prednisolone (PRD) for effective management of neurocysticercosis (NCC). METHODS LA was coupled to SLN by post-insertion technique. SLNs were characterized for particle size and size distribution, shape, and percent drug entrapment efficiency. In vitro drug release kinetics, fluorescence study and in vitro transendothelial transport, hematological studies and pharmacokinetic studies were carried out to predict the fullest drug delivery potential. RESULTS Spherical SLNs (~100 nm) with good drug entrapments (~64 and ~78% for ALB and PRD, respectively) showed in vitro initial fast release (i.e., 20-40% drugs release in 4 h) followed by sustained release for more than 48 h. Fluorescence study and in vitro transendothelial transport depicted selective brain uptake of SLN-LA compared to SLN attributed to carrier mediated transport via monocarboxylic acid transporters (MCT - 1/2/3). Pharmacokinetic parameters such as AUC0-t and AUMC0-t and Cllast showed good drugs withholding capacity of SLNs. Organ distribution studies reflected high accumulation of drugs (ALB, 7.6 ± 0.31%; PRD, 5.21 ± 0.24%) in the brain after 24 h in case of SLN-LA as compared to plain drugs solution. SLN-LA in hematological studies revealed insignificant toxicity to blood cells. CONCLUSIONS The overall study paved the potential advances in brain targeting with synergistic acting drugs for effective management of NCC.

Abstract
Although many agents have therapeutic potentials for central nervous system (CNS) diseases, few of these agents have been clinically used because of the brain barriers. As the protective barrier of the CNS, the blood–brain barrier and the blood–cerebrospinal fluid barrier maintain the brain microenvironment, neuronal activity, and proper functioning of the CNS. Different strategies for efficient CNS delivery have been studied. This article reviews the current approaches to open or facilitate penetration across these barriers for enhanced drug delivery to the CNS. These approaches are summarized into three broad categories: noninvasive, invasive, and miscellaneous techniques. The progresses made using these approaches are reviewed, and the associated mechanisms and problems are discussed.

Abstract
Cholesterol-mediated cationic solid lipid nanoparticles (CSLNs) were formulated with esterquat 1 (EQ 1) and stearylamine as positively charged external layers on hydrophobic internal cores of cacao butter. These CSLNs were employed to deliver saquinavir (SQV) to the brain. The permeability of SQV across the blood-brain barrier (BBB) using SQV-loaded CSLNs (SQV-CSLNs) was estimated with an in vitro model of a monolayer of human brain-microvascular endothelial cells (HBMECs) regulated by human astrocytes. The results revealed that the average diameter of SQV-CSLNs diminished when the weight percentage of cholesterol and EQ 1 increased. The morphological images indicated a uniform size of SQV-CSLNs with compact lipid structure. In addition, an increasing weight percentage of cholesterol and EQ 1 enhanced the zeta potential of SQV-CSLNs. The fluorescent staining demonstrated that HBMECs could internalize SQV-CSLNs. An increase in the weight percentage of cholesterol and EQ 1 also promoted the uptake of SQV-CSLNs by HBMECs. Moreover, a high content of cholesterol and EQ 1 in SQV-CSLNs increased the BBB permeability of SQV. The cholesterol-mediated SQV-CSLNs can be an efficacious drug delivery system for brain-targeting delivery of antiviral agents.
