Hepatocellular carcinoma is one of the severest malignant tumors with high mortality in patients. Sorafenib, a first-line drug, is extensively used for treating hepatocellular carcinoma. However, the efficacy of this chemotherapy treatment is limited in clinically due to the obstacles including rapid drug clearance from blood circulation, tumor drug resistance, and obvious adverse effects. To address those problems mentioned above, pH-sensitive hyaluronic acid nanoparticles were synthesized by crosslinking hyaluronic acid with cisplatin and encapsulating with sorafenib...

Chronic tympanic membrane perforation is a tubotympanic disease caused by traumatic or inflammatory factors. To date, numerous therapeutic methods have been used to heal tympanic membrane perforations. However, stem cell-based therapies have been used only rarely for the regeneration of chronic tympanic membrane perforations, because tympanic membrane is always exposed to the external environment. Therefore, the use of latent stem cells to treat the tympanic membrane may be possible for the regeneration of chronic tympanic membrane perforations...

Due to their excellent biocompatibility and suitable elastic modulus, carbon-carbon composites have excellent prospects for a wide range of applications such as artificial joints and bone replacements. However, the hydrophobicity and poor bioactivity limit their application in bone repair and substitution. Herein, a two-step surface modification of carbon-carbon composites was proposed to overcome these disadvantages. A polydopamine (PDA) layer was first deposited on the surface of carbon-carbon composites, followed by covalent coupling with arginine-glycine-aspartic acid (RGD) in varying concentrations...

Copper nanoparticles stabilized with cashew (CG-CuNPs) were synthesized by reduction reaction using ascorbic acid and sodium borohydride, using the cashew gum (CG) as a natural polymer stabilizer. Dynamic light scattering, atomic force microscopy, Fourier-transform infrared spectroscopy, UV-Vis spectrophotometry, and x-ray diffraction were used to characterize the nanoparticles (CG-CuNPs), and copper was quantified by electrochemical measurement. The UV-vis spectra of the CG-CuNPs confirmed the formation of nanoparticles by appearance of a surface plasmon band at 580 nm after 24 h of reaction...

The recent developments in the area of using starch in ceramics cover such fields like ceramic powders synthesis, where starch can be a polymerizing agent in sol-gel method or substrate for carbon spheres in hydrothermal synthesis, traditional ceramics manufacturing in which starch and its derivatives are being used as binders, rheological modifiers or even strengthening agents, as well as porous ceramics and bioceramics where starch plays mostly a role of pore forming agent. Due to the low dimensional changes occurring during the consolidation process, starch can help to control porosity of the bioceramics, which leads to better mechanical properties of the final product...

In addition to serve as a physical scaffold, acellular scaffold should be involved in tissue repair processes such as hemostasis, inflammation, proliferation, and remodeling/regeneration as a bioactive material. The biological activities of acellular scaffold related to free amine groups may have a great influence on tissue repairing process after in situ implantation. In order to investigate the role of free amine groups in acellular scaffold on tissue repairing/regeneration process, the amine-blocked acellular scaffolds and amine-unblocked acellular scaffolds were prepared by using bovine pericardia...

Liver cancer is one of the most common malignant tumors. Chemotherapy drugs have been widely used in the anti-hepatoma research. However, low targeting efficiency and serious adverse reaction are their main drawbacks. Liver tumor was proved to have a slightly acidic microenvironment (pH 4.5-5.5) and many glycyrrhetinic-acid-specific binding sites. Therefore, in the present study, the glycyrrhetinic acid- and hydrazone bond-modified micelles were designed. mPEG-HZ-PLA and GA-PEG-PLA copolymer were synthesized to prepare glycyrrhetinic-acid-modified pH-sensitive polymeric micelles (GA-PEG-HZ-PLA)...
