Abstract
Folate receptor-targeted therapy has excellent prospects for the treatment of breast cancer. A non-toxic concentration of folate-conjugated palladium-based nanoparticles was used to target the overexpressed folate receptor on breast cancer cells. The folate-conjugated nanoparticles were tailored to accumulate selectively in cancer cells relative to normal cells via the folate receptor. The MDA-MB-231, MDA-MB-468, MCF-7 breast cancer cell lines, and MCF-10A normal cell lines were used in the study. Qualitative and quantitative analysis of nanoparticle cellular uptake and accumulation was conducted using transmission electron microscopy and inductively coupled plasma-optical emission spectroscopy. The findings proved that folate-conjugated palladium nanoparticles successfully and preferentially accumulated in breast cancer cells. We conclude that folate-conjugated palladium nanoparticles can be potentially used to target breast cancer cells for radiopharmaceutical applications.

Abstract
Continuous drug delivery modification is the scientific approach and is a basic need for the efficient therapeutic efficacy of active drug molecules. Polymer-drug conjugates have long been a hallmark of the drug delivery sector, with various conjugates on the market or in clinical trials. Improved drug solubilization, extended blood circulation, decreased immunogenicity, controlled release behavior, and increased safety are the advantages of conjugating drugs to the polymeric carrier like polyethylene glycol (PEG). Polymer therapies have evolved over the last decade, resulting in polymer-drug conjugates with diverse topologies and chemical properties. Traditional nondegradable polymeric carriers like PEG and hydroxy propyl methacrylate have been clinically employed to fabricate polymer-drug conjugates. Still, functionalized polymer-drug conjugates are increasingly being used to increase localized drug delivery and ease of removal. Researchers have developed multifunctional carriers that can "see and treat" patients using medicinal and diagnostic chemicals. This review focused on the various conjugation approaches for attaching the doxorubicin to different polymers to achieve enhanced therapeutic efficacy, that is, increased bioavailability and reduced adverse effects.

Abstract
Biodegradable conductive polymers are currently of significant interest in tissue repair and regeneration, drug delivery, and bioelectronics. However, biodegradable materials exhibiting both conductive and elastic properties have rarely been reported to date. To that end, an electrically conductive polyurethane (CPU) was synthesized from polycaprolactone diol, hexadiisocyanate, and aniline trimer and subsequently doped with (1S)-(+)-10-camphorsulfonic acid (CSA). All CPU films showed good elasticity within a 30% strain range. The electrical conductivity of the CPU films, as enhanced with increasing amounts of CSA, ranged from 2.7 ± 0.9 × 10(-10) to 4.4 ± 0.6 × 10(-7) S/cm in a dry state and 4.2 ± 0.5 × 10(-8) to 7.3 ± 1.5 × 10(-5) S/cm in a wet state. The redox peaks of a CPU1.5 film (molar ratio CSA:aniline trimer = 1.5:1) in the cyclic voltammogram confirmed the desired good electroactivity. The doped CPU film exhibited good electrical stability (87% of initial conductivity after 150 hours charge) as measured in a cell culture medium. The degradation rates of CPU films increased with increasing CSA content in both phosphate-buffered solution (PBS) and lipase/PBS solutions. After 7 days of enzymatic degradation, the conductivity of all CSA-doped CPU films had decreased to that of the undoped CPU film. Mouse 3T3 fibroblasts proliferated and spread on all CPU films. This developed biodegradable CPU with good elasticity, electrical stability, and biocompatibility may find potential applications in tissue engineering, smart drug release, and electronics. © 2016 Wiley Periodicals, Inc.

Abstract
We show that Staphylococcus epidermidis, a commensal bacterium in the human skin microbiome, produces short-chain fatty acids by glycerol fermentation that can induce adipogenesis. Although the antimicrobial and anti-inflammatory activities of short-chain fatty acids have been previously well characterized, little is known about the contribution of short-chain fatty acids to the adipogenic differentiation of adipose-derived stem cells (ADSCs). We show that ADSCs differentiated into adipocytes and accumulated lipids in the cytoplasm when cultured with butyric acid, a principal short-chain fatty acid in the fermentation metabolites of S. epidermidis. Additionally, a co-drug, butyric acid 2-(2-butyryloxyethoxy) ethyl ester (BA-DEG-BA), released active butyric acid when it was intradermally injected into mouse ears and induced ADSC differentiation, characterized by an increased expression of cytoplasmic lipids and perilipin A. The BA-DEG-BA-induced adipogenic differentiation was mediated via peroxisome proliferator-activated receptor gamma. Furthermore, intradermal injection of ADSCs along with BA-DEG-BA into mouse ears markedly enhanced the adipogenic differentiation of ADSCs, leading to dermal augmentation. Our study introduces BA-DEG-BA as an enhancer of ADSC adipogenesis and suggests an integral interaction between the human skin microbiome and ADSCs.

Abstract
PURPOSE Since the introduction of nanocarriers, the delivery of chemotherapeutic agents for treatment of patients with cancer has been possible with better effectiveness. The latest findings are also support that further enhancement in therapeutic effectiveness of these nanocarriers can be attained, if surface decoration with proper targeting agents is considered. METHODS This study aimed at treating a variety of 4T1 murine breast cancer cell line, mainly demonstrating high folate and TRAIL receptor expression of cancerous cells. The therapeutic efficacy of paclitaxel loaded Cremophore EL (Taxol®), paclitaxel loaded waterborne polyurethane nanomicelles (PTX-PU) and paclitaxel loaded waterborne polyurethane nanomicelles conjugated with folate (PTX-PU-FA) and TRAIL (PTX-PU-TRAIL) on treating 4T1 cell was also compared. RESULTS The findings that worth noting are: PTX-PU outperformed Taxol® in a Balb/C mouse model, furthermore, tumor growth was adequately curbed by folate and TRAIL-decorated nanomicelles rather than the unconjugated formulation. Tumors of mice treated with PTX-PU-FA and PTX-PU-TRAIL shrank substantially compared to those treated with Taxol®, PTX-PU and PTX-PU-TRAIL (average 573 mm(3) versus 2640, 846, 717 mm(3) respectively), 45 days subsequent to tumor inoculation. The microscopic study of hematoxylin-eosin stained tumors tissue and apoptotic cell fraction substantiated that the most successful therapeutic effects have been observed for the mice treated with PTX-PU-FA (about 90% in PTX-PU-FA versus 75%, 60%, 15% in PTX-PU-TRAIL, PTX-PU, and Taxol® group respectively). CONCLUSIONS Using folate-targeted nanocarriers to treat cancers characterized by a high level of folate ligand expression is well substantiated by the findings of this study.

Abstract
PURPOSE There is significant interest in the application of nanoparticles to deliver immunostimulatory signals to cells. We hypothesized that curdlan (immune stimulating polymer) could be conjugated to PLGA and nanoparticles from this copolymer would possess immunostimulatory activity, be non-cytotoxic and function as an effective sustained drug release system. METHODS Carbodiimide chemistry was employed to conjugate curdlan to PLGA. The conjugate (C-PLGA) was characterized using (1)H and (13)C NMR, FTIR, DSC and TGA. Nanoparticles were synthesized using an emulsion-solvent evaporation technique. Immunostimulatory activity was characterized in THP-1 derived macrophages. MTT assay and real-time impedance measurements were used to characterize polymer and nanoparticle toxicity and uptake in macrophages. Drug delivery capability was assessed across Caco-2 cells using rifampicin as a model drug. RESULTS Spectral characterization confirmed successful synthesis of C-PLGA. C-PLGA nanoparticles enhanced phosphorylated ERK production in macrophages indicating cell stimulation. Nanoparticles provided slow release of rifampicin across Caco-2 cells. Polymers but not nanoparticles altered the adhesion profiles of the macrophages. Impedance measurements suggested Ca(2+) dependent uptake of nanoparticles by the macrophages. CONCLUSIONS PLGA nanoparticles with macrophage stimulating and sustained drug delivery capabilities have been prepared. These nanoparticles can be used to stimulate macrophages and concurrently deliver drug in infectious disease therapy.

Abstract
The shape of polymer micelles is important for pharmaceutical applications as drug delivery. In this article, an approach inducing sphere-to-rod transition of multiblock polyurethane micelles has been developed through introducing a second hydrophilic component phosphatidylcholine group into the polymer chains. Time-resolved dynamic light scattering (DLS), combined with transmission electron microscopy (TEM), was employed to investigate the kinetics of morphology transition. Moreover, a dissipative particle dynamics (DPD) simulation method was applied to study the mechanism of sphere-to-rod transition. These experimental and simulation studies revealed that the hydrophilic phosphatidylcholine groups can create defects on the surfaces of spherical polyurethane micelles, thus, making positive contribution to adhesive collisions and leading to the fusion of spherical micelles into rod-like micelles. This finding provides new insight into the origins of rod-like polymer micelles, which is valuable for the design and preparation of novel polymeric drug carriers with tailored properties.

Abstract
Cyclodextrin-conjugated poly(lactic acid)-b-poly(ethylene glycol) (β-CD-PLA-mPEG), a well-defined amphiphilic copolymer, was synthesized by controlled ring-open copolymerization and click coupling reaction, in order to obtain a biocompatible drug delivery system with controlled release profiles. The β-CD-PLA-mPEG copolymer could self-assemble in aqueous solution to form micelles with a mean particle size of 173.4 nm, which will decrease to 159.2 nm after loaded with a kind of hydrophobic drug (indomethacin, IND). The IND-loaded β-CD-PLA-mPEG micelles show spherical shape within the nano-size scale under TEM imaging. Compared with that formed by PLA-mPEG, the micelles formed by β-CD-PLA-mPEG copolymer present higher drug loading efficiency and controlled release profile of IND, especially in the control of its initial burst release. Meanwhile, β-CD-PLA-mPEG copolymer exhibits low toxicity to cells. The micelles formed by β-CD-PLA-mPEG copolymer could be a promising controlled release system for various hydrophobic drugs.

Abstract
AIM In the present investigation, vancomycin (VCM) biodegradable nanoparticles were developed for oral administration, with the aim of improving its intestinal permeability. METHODS The vancomycin-loaded nanoparticles were prepared using double-emulsion solvent evaporation method. The prepared nanoparticles were characterized for their micromeritic and crystallographic properties, particle size, zeta potential, drug loading and release. Intestinal permeability of VCM nanoparticles was determined in different concentrations using SPIP technique in rats. RESULTS Particle sizes were between 450 nm and 466 nm for different compositions of VCM-PLGA nanoparticles. Entrapment efficiency ranged between 38.38% and 78.6% with negative zeta (ζ) potential. The FT-IR, XRPD and DSC results ruled out any chemical interaction between the drug and PLGA. Effective intestinal permeability values of VCM nanoparticles in concentrations of 200, 300 and 400 μg/ml were significantly higher than that of solutions at the same concentrations. CONCLUSION Our findings suggest that PLGA nanoparticles could provide a delivery system for VCM, with enhanced intestinal permeability.
