Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE The purpose of this study was to develop an active targeting strategy to improve the therapeutic antitumor efficacy of oridonin (ORI), the main active ingredient in the medicinal herb Rabdosia rubescens. METHODS A modified spontaneous emulsification solvent diffusion method was used to

Doxorubicin-loaded electrospun poly(l-lactic acid)/mesoporous silica nanoparticles composite nanofibers for potential postsurgical cancer treatment.

Numai utilizatorii înregistrați pot traduce articole

A drug-loaded implantable scaffold is a promising alternative for the treatment of a tissue defect after tumor resection. In this study, mesoporous silica nanoparticles (MSNs) were used as carriers to load an anticancer drug - doxorubicin hydrochloride (DOX), and the DOX-loaded MSNs (DOX@MSNs) were

Tumor pH-responsive flower-like micelles of poly(L-lactic acid)-b-poly(ethylene glycol)-b-poly(L-histidine).

Polymeric micelles were constructed from poly(l-lactic acid) (PLA; M(n) 3K)-b-poly(ethylene glycol) (PEG; M(n) 2K)-b-poly(l-histidine) (polyHis; M(n) 5K) as a tumor pH-specific anticancer drug carrier. Micelles (particle diameter: approximately 80 nm; critical micelle concentration (CMC): 2

Tumour embolization of the Vx2 rabbit head and neck cancer model with Dextran hydrogel and Holmium-poly(L-lactic acid) microspheres: a radionuclide and histological pilot study.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Intra-arterial embolization of unresectable malignant tumours with biodegradable microspheres is an effective way of selective anti-tumour therapy. Promising candidates are Dextran hydrogel (Dex) microspheres for chemo-embolization and Holmium-166 poly(L-lactic acid) (166HoPLA)

Preferential tumor accumulation and desirable interstitial penetration of poly(lactic-co-glycolic acid) nanoparticles with dual coating of chitosan oligosaccharide and polyethylene glycol-poly(D,L-lactic acid).

Numai utilizatorii înregistrați pot traduce articole

Despite advances in polymeric nanoparticles (NPs) as effective delivery systems for anticancer drugs, rapid clearance from blood and poor penetration capacity in heterogeneous tumors still remain to be addressed. Here, a dual coating of poly (ethylene glycol)-poly (d,l-lactic acid) (PEG-PDLLA) and

Cellulose-graft-poly(l-lactic acid) nanoparticles for efficient delivery of anti-cancer drugs.

Numai utilizatorii înregistrați pot traduce articole

Cellulose based carriers have the potential for sustained release of drugs, which can protect drugs and deliver them to the target site. Herein, BA-loaded cellulose-graft-poly(l-lactic acid) nanoparticles (CE-g-PLLA/BA NPs) were fabricated by employing cellulose (CE) and poly(l-lactic acid) (PLLA)

Near-infrared fluorescence tumor imaging using nanocarrier composed of poly(L-lactic acid)-block-poly(sarcosine) amphiphilic polydepsipeptide.

Numai utilizatorii înregistrați pot traduce articole

A nanocarrier, lactosome, which is composed of poly(L-lactic acid)-block-poly(sarcosine), as a contrast agent for the liver tumor imaging was examined using the near infrared fluorescence (NIRF) optical imaging technique. Lactosome labeled with indocyanine green (ICG) showed a high escape ability

Biodegradable thermo-sensitive nanoparticles from poly(L-lactic acid)/poly(ethylene glycol) alternating multi-block copolymer for potential anti-cancer drug carrier.

Numai utilizatorii înregistrați pot traduce articole

In order to produce biodegradable thermo-sensitive nanoparticles, alternating multi-block copolymers (MBC) were synthesized by coupling dicarboxylated poly(ethylene glycol) (PEG; M(w) 2000) with poly(L-lactic acid) (PLLA)/PEG/PLLA triblock copolymers. Three different multi-block copolymers were

Bio-responsive chitin-poly(L-lactic acid) composite nanogels for liver cancer.

Numai utilizatorii înregistrați pot traduce articole

Hepatic carcinoma (HCC) is one of the most common cancer and its treatment has been considered a therapeutic challenge. Doxorubicin (Dox) is one of the most important chemotherapeutic agents used in the treatment for liver cancer. However, the efficacy of Dox therapy is restricted by the

Solid tumor chemotherapy and in vivo distribution of fluorouracil following administration in poly(L-lactic acid) microspheres.
