Abstract
Disorders of the central nervous system (CNS) which include a wide range of neurodegenerative and neurological conditions have become a serious global issue. The presence of CNS barriers poses a significant challenge to the progress of designing effective therapeutic delivery systems, limiting the effectiveness of drugs, genes, and other therapeutic agents. Natural nanocarriers present in biological systems have inspired researchers to design unique delivery systems through biomimicry. As natural resource derived delivery systems are more biocompatible, current research has been focused on the development of delivery systems inspired by bacteria, viruses, fungi, and mammalian cells. Despite their structural potential and extensive physiological function, making them an excellent choice for biomaterial engineering, the delivery of nucleic acids remains challenging due to their instability in biological systems. Similarly, the efficient delivery of genetic material within the tissues of interest remains a hurdle due to a lack of selectivity and targeting ability. Considering that gene therapies are the holy grail for intervention in diseases, including neurodegenerative disorders such as Alzheimer's disease, Parkinson's Disease, and Huntington's disease, this review centers around recent advances in bioinspired approaches to gene delivery for the prevention of CNS disorders.

Abstract
This study reports the use of biocompatible and biodegradable polymers for the formulation and design of an implantable multipolymeric drug delivery device (MDDD) for the management of AIDS dementia complex (ADC), a debilitating condition affecting the cognitive, motor and behavioral systems in HIV+ individuals. A 3-factor Box-Behnken statistical design was employed for the optimization of nanoparticle and multipolymeric scaffold formulations. Fifteen formulations were generated using the Box-Behnken template, which were assessed for physicochemical and physicomechanical characterization. The optimised nanoparticle formulation yielded nanoparticles measuring 68.04nm in size and zeta potential (ZP) of -13.4mV was calculated for the colloidal system. In an attempt to further retard drug release and to formulate a device for implantation in the frontal lobe of the brain, nanoparticles were dispersed within a multipolymeric matrix. Matrix erosion was calculated at 28% for multipolymeric scaffold and a matrix resilience of 4.451% was observed 30 days post exposure to PBS, indicating slow degradation of the MDDD. In vivo studies showed 12.793ng/mL and 35.225ng/mL AZT level in plasma and CSF. In view of the physicomechanical properties, in vitro and in vivo drug release kinetics of MDDD makes it a potential candidate for the management of the ADC.

Abstract
Antrodia camphorata is a well-known medicinal mushroom in Taiwan and has been studied for decades, especially with focus on anti-cancer activity. Polysaccharides are the major bioactive compounds reported with anti-cancer activity, but the debates on how they target cells still remain. Research addressing the encapsulation of polysaccharides from A. camphorata extract (ACE) to enhance anti-cancer activity is rare. In this study, ACE polysaccharides were nano-encapsulated in chitosan-silica and silica (expressed as ACE/CS and ACE/S, respectively) to evaluate the apoptosis effect on a hepatoma cell line (Hep G2). The results showed that ACE polysaccharides, ACE/CS and ACE/S all could damage the Hep G2 cell membrane and cause cell death, especially in the ACE/CS group. In apoptosis assays, DNA fragmentation and sub-G1 phase populations were increased, and the mitochondrial membrane potential decreased significantly after treatments. ACE/CS and ACE/S could also increase reactive oxygen species (ROS) generation, induce Fas/APO-1 (apoptosis antigen 1) expression and elevate the proteolytic activities of caspase-3, caspase-8 and caspase-9 in Hep G2 cells. Unsurprisingly, ACE/CS induced a similar apoptosis mechanism at a lower dosage (ACE polysaccharides = 13.2 μg/mL) than those of ACE/S (ACE polysaccharides = 21.2 μg/mL) and ACE polysaccharides (25 μg/mL). Therefore, the encapsulation of ACE polysaccharides by chitosan-silica nanoparticles may provide a viable approach for enhancing anti-tumor efficacy in liver cancer cells.

Abstract
Due to their high chemical stability, lithium titanate (Li2TiO3) nanoparticles (LTT NPs) now are projected to be transferred into different nanotechnology areas like nano pharmacology and nano medicine. With the increased applications of LTT NPs for numerous purposes, the concerns about their potential human toxicity effects and their environmental impact are also increased. However, toxicity data for LTT NPs related to human health are very limited. Therefore we aimed to investigate toxicity potentials of various concentrations (0-1,000 ppm) of LTT NPs (<100 nm) in cultured primary rat hepatocytes. Cell viability was detected by [3-(4,5-dimethyl-thiazol-2-yl) 2,5-diphenyltetrazolium bromide] (MTT) assay and lactate dehydrogenase (LDH) release, while total antioxidant capacity (TAC) and total oxidative stress (TOS) levels were determined to evaluate the oxidative injury. DNA damage was analyzed by scoring liver micronuclei rates and by determining 8-oxo-2-deoxyguanosine (8-OH-dG) levels. The results of MTT and LDH assays showed that higher concentrations of dispersed LTT NPs (500 and 1,000 ppm) decreased cell viability. Also, LTT NPs increased TOS (300, 500 and 1,000 ppm) levels and decreased TAC (300, 500 and 1,000 ppm) levels in cultured hepatocytes. The results of genotoxicity tests revealed that LTT NPs did not cause significant increases of micronucleated hepatocytes and 8-OH-dG as compared to control culture. In conclusion, the obtained results showed for the first time that LTT NPs had dose dependent effects on oxidative damage and cytotoxicity but not genotoxicity in cultured primary rat hepatocytes for the first time.

Abstract
UNLABELLED The last decade has brought many examples of utilization of dendrimers as drug delivery systems; however, their possible application is limited because of inherent toxicity associated with them. This study discusses the influence of G1-G4 PAMAM-NH2 dendrimers on the process of hemostasis and integrity of endothelial monolayer. The global assay of coagulation and fibrinolysis was investigated spectrophotometrically by means of CL-test at 405 nm. Thrombin (0.5 I U/mL) and t-PA (240 ng/mL) were used to obtain clotting and lysis curve. The activity of thrombin was determined by means of chromogenic substrate S-2238. The influence of PAMAM dendrimers on the barrier properties of human primary aortal endothelium was assessed by means of method based on the measurements of the impedance changes of the cells. Observed multidirectional impact of dendrimers, without affecting the thrombin activity, on clot formation, its stabilization and fibrinolysis could be regarded as important when trying to use them clinically. It is crucial that examined PAMAM dendrimers did not lead to spontaneous aggregation of fibrinogen. Importantly, examined polymers have concentration- and generation-dependent adverse effect towards the endothelial monolayer. RESULT of described studies provide additional insight into PAMAM dendrimers toxicity associated with systemic administration and underscore the necessity for further research.

Abstract
PURPOSE To evaluate the effect of borneol on the brain targeting efficiency of aprotinin-conjugated poly (ethyleneglycol)-poly (L-lactic-co-glycolic acid) nanoparticles (Apr-NP) and the activity of huperzine A (Hup A) loaded nanoparticles to AD rats . METHOD Apr-NP was prepared by emulsion and solvent evaporation method. The uptake of Apr-NP alone or combined with borneol by brain capillary endothelial cells (BCECs) was evaluated by incorporating coumarin-6 as a tracer. In vivo imaging and the distribution of Hup A in the brain were measured to investigate the brain delivery of Apr-NP in rats, with or without the oral administration of borneol. Morris water maze was used to evaluate the memory improvement effect of Hup A loaded nanoparticles (Apr-NP-Hup). RESULTS Co-incubation with borneol could increase the uptake of nanoparticles by BCECs. Nanoparticles delivered into the rat brain were enhanced significantly by the co-administration of borneol. The pharmacological effects of Hup A loaded nanoparticles on improving the memory impairment of AD rats were greatly improved when combined with borneol. CONCLUSIONS Borneol is a promising enhancer for brain-targeting delivery systems. When co-administered with aprotinin-modified nanoparticles, borneol could improve the brain targeting efficiency of nanoparticles significantly.

Abstract
Multiple Sclerosis is a multifactorial disease with several pathogenic mechanisms and pathways. Successful MS management and medical care requires early accurate diagnosis along with specific treatment protocols based upon multifunctional nanotechnology approach. This paper highlights advances in nanotechnology that have enabled the clinician to target the brain and CNS in patient with multiple sclerosis with nanoparticles having therapeutic and imaging components. The multipartite theranostic (thera(py) + (diag)nostics) approach puts forth strong implications for medical care and cure in MS. The current nanotheranostics utilize tamed drug vehicles and contain cargo, targeting ligands, and imaging labels for delivery to specific tissues, cells, or subcellular components. A brief overview of nonsurgical nanorepair advances as future perspective is also described. Considering the potential inflammatory triggers in MS pathogenesis, a multifunctional nanotechnology approach will be needed for the prognosis.

Abstract
The interactions between dendrimers and different types of drugs are nowadays one of the most actively investigated areas of the pharmaceutical sciences. The interactions between dendrimers and drugs can be divided into: internal encapsulation, external electrostatic interaction, and covalent conjugation. In the present study, we investigated the potential of poly(amidoamine) (PAMAM) dendrimers for solubility of four iminodiacetic acid derivatives. We reported that PAMAM dendrimers contribute to significant solubility enhancement of iminodiacetic acid analogues. The nature of the dendrimer–drug complexes was investigated by 1H NMR and 2D-NOESY spectroscopy. The 1H NMR analysis proved that the water-soluble supramolecular structure of the complex was formed on the basis of ionic interactions between terminal amine groups of dendrimers and carboxyl groups of drug molecules, as well as internal encapsulation. The 2D-NOESY analysis revealed interactions between the primary amine groups of PAMAM dendrimers and the analogues of iminodiacetic acid. The results of solubility studies together with 1H NMR and 2D-NOESY experiments suggest that the interactions between PAMAM dendrimers of generation 1–4 and derivatives of iminodiacetic acid are based on electrostatic interactions and internal encapsulation.
