Targeting drugs to their sites of action is still a major challenge in pharmaceutical research. In this study, polylactic-co-glycolic acid (PLGA) immuno-nanoparticles were prepared for targeting invasive epithelial breast tumour cells. Monoclonal antibody (mAb) was used as a homing ligand and was attached to the nanoparticle surface either covalently or non-covalently. The presence of mAb on th...

Cancer stem cells (CSCs) have the ability to transform into bulk cancer cells, to promote tumor growth and establish tumor metastasis. To effectively inhibit tumor growth and prevent metastasis, treatments with conventional chemotherapy drugs should be combined with CSC targeted drugs. In this study, we describe the synthesis and characterization of a new amphiphilic polymer, hyaluronic acid-cy...

Heart disease is a common medical condition that affects hundreds of thousands of people each year in the United States alone. In response, scientists have spent decades researching technologies to treat this disease. Coronary stents are a technology developed to keep collapsing heart vessels open to promote proper blood flow and prevent further cardiovascular complications. Since the 1970s, th...

Polylactic acid (PLA) is considered a mature alternative to synthetic plastics made from petroleum by-products, possessing the advantages of good mechanical strength. However, it also has some disadvantages such as brittleness and low toughness. In order overcome improve these unfavorable properties, PLA/PBAT composites were prepared by blending PLA with Poly (butylene adipate-co-terephthalate)...

Lactic acid is an important biochemical product. With the global pollution caused by plastics, especially marine demand for lactic to produce polylactic has rapidly increased. However, high costs of raw materials and fermentation–separation processes have severely limited production. In this study, research trend on fermentation in recent years was analyzed a bibliometric survey, latest progres...

BACKGROUND Drug nano-carriers are one of the most important tools for targeted cancer therapy so that undesired side effects of chemotherapy drugs are minimized. In this area, the use of ultrasound can be helpful in controlling drug release from nanoparticles to achieve higher treatment efficiency. OBJECTIVE Here, we studies the effects of ultrasound irradiation on the release profile of 5-fl...

Staphylococcus aureus is an important cause of nosocomial and community-acquired infections in humans and animals, as well as the cause of mastitis in dairy cattle. Vaccines aimed at preventing S. aureus infection in bovine mastitis have been studied for many years, but have so far been unsuccessful due to the complexity of the bacteria, and the lack of suitable vaccine delivery vehicles. The c...
