The eye is a model organ for the local delivery of therapeutics. This proves beneficial when treating vitreous inflammation and other ophthalmic pathologies. The chronicity of certain diseases, however, limits the effectiveness of locally administered drugs. To maintain such treatments often requires frequent office visits and can result in increased risk of infection and toxicity to the patien...

delivery of exogenous materials such as nucleic acids, peptides, proteins, and drugs into cells is an important strategy in modern cellular and molecular biology. recently, the development of gene carriers for efficient gene transfer into cells has attracted a great attention. furthermore, lack of effective drug delivery is one of the major problems of cancer chemotherapy. many physical methods...

Drug-Eluting Stents (DES) have greatly impacted treatment methods for cardiovascular disease over the past ten years. Patients receiving DES treatments have a significantly reduced risk of in-stent restenosis, but other risks, such as particulate matter generation, have caused concern in recent years. Particulate matter can be generated by the manufacturing process or from the breakdown of any ...

the goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. the mesoporous silica nanoparticles were prepared by using tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); the prepared nanoparti...

although the conventional therapies have obviously improved the conditions of patients with cancer, some mechanisms of resistance have led scientists to use alternative agents that can penetrate in most solid tumors. furthermore, the success of cancer therapies depends on limiting the uptake of toxins to normal tissues and their selectivity to malignant cells. the involvement of natural and gen...

Ketorolac is a potent non-steroidal drug with potent analgesic and anti-inflammatory activity. Its oral administration is associated with a high risk of adverse effects such as irritation, ulceration and bleeding of gastrointestinal tract. The present study focuses on the development of controlled release drug delivery system of ketorolac microcapsules as one of the multi-particulate formulatio...
