Abstract
This study aimed to synthesize and characterize DTX-mPEG-PLA-NPs along with the development and validation of a simple, accurate, and reproducible method for the determination and quantification of DTX in mPEG-PLA-NPs. The prepared NPs were characterized using AFM, DLS, zetasizer, and drug release kinetic profiling. The RP-HPLC assay was developed for DTX detection. The cytotoxicity and anti-clonogenic effects were estimated using MTT and clonogenic assays, respectively, using both MCF-7 and MDA-MB-231 cell lines in a 2D and 3D culture system. The developed method showed a linear response, high precision, accuracy, RSD values of ≤2%, and a tailing factor ≤2, per ICH guidelines. The DTX-mPEG-PLA-NPs exhibited an average particle size of 264.3 nm with an encapsulation efficiency of 62.22%. The in vitro drug kinetic profile, as per the Krosmeyers-Peppas model, demonstrated Fickian diffusion, with initial biphasic release and a multistep sustained release over 190 h. The MTT assay revealed improved in vitro cytotoxicity against MCF-7 and MDA-MB-231 in the 2D cultures and MCF-7 3D mammosphere cultures. Significant inhibitions of the clonogenic potential of MDA-MB-231 were observed for all concentrations of DTX-mPEG-PLA-NPs. Our results highlight the feasibility of detecting DTX via the robust RP-HPLC method and using DTX-mPEG-PLA-NPs as a perceptible and biocompatible delivery vehicle with greater cytotoxic and anti-clonogenic potential, supporting improved outcomes in BC.

Abstract
Combining photothermal and chemotherapy is an emerging strategy for tumor irradiation in a minimally invasive manner, utilizing photothermal transduction agents and anticancer drugs. The present work developed a 2D carbon nanomaterial graphene oxide (GO)-based nanoplatform that converted to 3D colloidal spherical structures upon functionalization with an amphiphilic polymer mPEG-PLA (1, 0.5/1/2) and entrapped doxorubicin (Dox) physically. The Dox@GO(mPP) (1/0.5) NPs displayed the least particle size (161 nm), the highest stability with no aggregation, the highest Dox loading (6.3 %) and encapsulation efficiency (70 %). The therapeutic efficacy was determined in vitro and in vivo using murine (4 T1) and human triple-negative breast cancer cells (MDA-MB-231), and 4 T1-Luc-tumor bearing mouse models. The results demonstrated that the Dox@GO(mPP) (1/0.5) NPs treatment with laser (+L) (808 nm) was highly efficient in inducing apoptosis, cell cycle arrest (G2/M) phase, significant cytotoxicity, mitochondrial membrane depolarization, ROS generation, and photothermal effect leading to a higher proportion of cell death than free Dox, and Dox@GO(mPP) (1/0.5) NPs (-L). The anticancer studies in mice harboring the 4 T1-Luc tumor showed that combination of Dox@GO(mPP) (1/0.5) NPs (+L) effectively reduced tumor development and decreased lung metastasis. The developed nanoplatform could be a promising combination chemo-photothermal treatment option for triple-negative breast cancer.

Abstract
OBJECTIVE In this study, methoxy poly(ethylene glycol)-b-poly(D,L-lactide), or mPEG-PLA, was used as the smart thermoresponsive polymer in our mascara formulation. The utility of mPEG-PLA in a mascara formulation was investigated by a stepwise build-up in an oil in water (O/W) emulsion. The experimental results may pave the way to a strategy of developing more cosmetic formulation with thermoresponsive shape memory polymers (SMPs). METHOD mPEG-PLA was first incorporated in a simple emulsion for rheological evaluation such as shear flow viscosity and small deformation oscillation measurements over the relevant temperature settings to mascara application. Then, wax and pigment were incorporated to complete the basic formulation as an O/W mascara and evaluated rheologically as before. Finally, the formulation was applied by a heated mascara applicator to false lashes to evaluate its curing and lifting effect. RESULTS With 0.8% concentration of mPEG-PLA, the viscosity was able to increase from 0.20 Pas·s to 1.00 Pas·s. At 1.0% concentration of mPEG-PLA, the emulsion samples with mineral oil were evaluated from 55°C to 25°C for its storage modulus (G') and were found to have a consistent shear-thinning characteristic across all temperature range. The sample containing the polymer (M-1) arrived at a markedly higher elasticity when compared against the sample without (M-0). The same result holds true for the set of samples formulated with beeswax instead of mineral oil. When the formulations were applied with a heated mascara applicator on false eyelashes, the formulation containing mPEG-PLA was found to produce a more pronounced and longer-lasting curl. CONCLUSION This preliminary rheological study of an O/W mascara containing mPEG-PLA demonstrated that thermoresponsive SMP can be added to enhance the curl and lifting effect of a mascara formulation.

Abstract
Total alkaloids of Alstonia scholaris leaves (ASAs) are extracted from the lamp leaves, which have positive anti-inflammatory activity and remarkable effects in treating bronchitis. Due to its short half-life, we used a degradable mPEG-PLA to physically encapsulate the total alkali of the lamp stage, and prepared a sustained-release microsphere by double-emulsion method. The ASAs-loaded mPEG10000-PLA microspheres were screened for better performance by testing the morphology, average particle size, embedding rate and drug loading of different molecular weight mPEG-PLA microspheres, which can stably and continuously release for 15 days at 37 °C. The results of cytotoxicity and blood compatibility indicated that the drug-loaded microspheres have beneficial biocompatibility. Animal experiments showed that the drug-loaded microspheres had a beneficial anti-inflammatory effect. These results all indicated that mPEG-PLA is a controlled release carrier material suitable for ASAs.

Abstract
To investigate the effect of end-capped modification of mPEG-PLA with Boc-phenylalanine(BP) on pharmacokinetic characteristics of curcumin(CUR) loaded micelles, and then provide experimental evidence for prescription optimization. Healthy male SD rats were randomly divided into three groups and they were intravenously administered with a single injection of CUR-mPEG-PLA micelles, CUR-mPEG-PLA-BP micelles and reference formulations DMSO solution(n=6). The doses were 20 mg•kg⁻¹ in term of CUR. Blood samples were collected before and after administration, and the concentration of curcumin in blood plasma was determined by HPLC to draw time-concentration curve. Non-compartmental pharmacokinetic parameters were calculated by using DAS 2.0 software and statistical analysis was conducted between the different groups. The results indicated that the pharmacokinetic characteristics of CUR-mPEG-PLA micelles were similar to those of the free drug of CUR dissolved in DMSO, and the main pharmacokinetic parameters had no significant difference between the two groups. However, as compared with CUR-mPEG-PLA micelles, CUR-mPEG-PLA-BP micelles had a significantly increased area under the time-concentration curve(AUC), significantly prolonged half-life of elimination(tl/2) and mean residence time(MRT), and reduced total body clearance(Cl) (P<0.05). In conclusion, the amphipathic block copolymer of mPEG-PLA-BP could provide curcumin loaded micelles with preferable pharmacokinetic properties in vivo, and CUR-mPEG-PLA-BP micelles were worthy of further research and development.

Abstract
The aim of present study was to develop VIN-loaded mPEG-PLA nanoparticle systems. The VIN mPEG-PLA nanoparticles were prepared using an emulsion solvent evaporation method, and studied their particle size, morphology, encapsulation efficiency and drug-loading coefficient. Moreover, the nanoparticles were evaluated on the drug release behaviors in vitro and bioavailability in vivo. The results show that the spherical nanoparticles obtained were negatively charged with a zeta potential of about -23.4 mV and characterized ∼110 nm with a narrow size distribution. The encapsulation efficiency and drug loading of prepared NPs were 76.4 ± 6.3 and 9.2 ± 2.2% (n=5), respectively. The in vitro release showed that the percent of accumulated dissolution of VIN NPs in phosphate-buffered saline 6.8 over 24 h was <80%, which was almost 100% of VIN in commercial injections. The in vivo study indicated that systemic absorption of VIN was significantly enhanced by incorporating into mPEG-PLA NPs compared with VIN injection (2.87-fold in AUC0-t). The results suggested that the form of VIN in mPEG-PLA NPs could enter the body circulation to perform sustained release in vitro and in vivo.

Abstract
To investigate the physicochemical properties, immunosafety and chronic toxicity of monomethoxypoly(ethylene glycol)-b-poly(lactic acid) (mPEG-PLA), a copolymer used as a carrier for paclitaxel (PTX) delivery. The H-Nuclear Magnetic Resonance (H-NMR), dynamic light scattering and fluorescence probe technique were conducted to determine the physicochemical properties of mPEG-PLA copolymer. PTX-loaded polymeric micelles were characterized regarding their particle size, entrapment efficiency (EE), drug loading (DL), in vitro drug release and hemolysis rate. The complement activation in human serum and mast cells degranulation were performed by ELISA and RBL-2H3 cell line in vitro, respectively. The chronic toxicity study was carried out on beagle dogs. The optimized PTX-loaded mPEG-PLA (40/60) micelles showed a particle size of 37 nm and EE of 98.0% with a DL of 17.0% w/w. Transmission electron microscopy (TEM) analyses showed that mPEG-PLA (40/60) micelles have spherical shape with dense core. In vitro release study showed a sustained release for 24 h, and the hemolysis study revealed that mPEG-PLA (40/60) was a safe nanocarrier for intravenous administration. mPEG-PLA (40/60) showed a lower complement activation ability compared to mPEG-PLA (50/50) and Cremophor® EL (Cr EL). Furthermore, the chronic toxicity of PTX-loaded mPEG-PLA (40/60) micelles was significantly lower than those of mPEG-PLA (50/50) and Cr EL.

Abstract
Targeted drug delivery system for tumor cells is an appealing platform on enhancing the therapeutic effects and reducing the side effects of the drug. In this study, we developed folate-modified curcumin (Cur) loaded micelles (Cur-FPPs) for cancer chemotherapy. The targeting material, Folate-PEG3000-PLA2000, was synthesized by the amide bond formation reaction. And the Cur loaded micelles were prepared by thin-film hydration method with mPEG2000-PLA2000 (Cur-PPs) or mPEG2000-PLA2000 and Folate-PEG3000-PLA2000 (Cur-FPPs) as carrier. A central composite design (CCD) was used to optimize the formulation, and the optimized Cur-FPPs was prepared with the weight ratio of Folate-PEG3000-PLA2000 and mPEG2000-PLA2000 at 1:9. The average size of the mixed micelles was 70nm, the encapsulating efficiency and drug-loading were 80.73±0.16% and 4.84±0.01%, respectively. Compared with the Cur propylene glycol solution, the in vitro release of Cur from Cur-FPPs showed a sustained manner. Furthermore, the in vitro cytotoxicity and cellular uptake of Cur-FPPs were significantly enhanced towards MCF-7 and HepG2 cells. The pharmacokinetic studies in rats indicated that a 3-fold increase in the half-life was achieved for Cur loaded micelle formulations relative to solubilized Cur. All the results demonstrated that folate-modified Cur micelles could serve as a potential nanocarrier to improve the solubility and anti-cancer activity of Cur.
