the development of efficient and safe carrier system to transfer dna into cells is essential in non-viral gene therapy. the aim of the present study was to evaluate the effect of linear polyetheneimine (lpei) (2500 da) on the physicochemical and biological properties of lipopolyplexes constructed from liposomes and lpei. materials and methods different lipopolymers were synthesized from lpei an...

Conveying the therapeutic agent to human eye has been a struggling task for formulators and scientists because of complicated arrangement eye. The agents needed deliver drugs specific sites require crossing various ocular barriers, which act as hitches drug delivery. Conventional preparations present in market do not achieve desired results due their lower bioavailability, less retention time, ...

Cosmetics attract most age groups from teenagers to old age. Cosmetic goods now contain a variety of nanoparticle and nanomaterial types. Nano cosmeceuticals have changed the era cosmetics as they advanced delivery mechanisms with task specifications. They are used in nail, hair, lip, skin care products by cosmetic giants including Estee Lauder, L’oreal, Nivea, Zelens, Derma Swiss, etc., patent...

Liposomes are widely used as drug delivery systems in different forms including osmotic pumps, infusion and IV injection. In spite of these, there is no data available about their behavior under convective flow (e.g. infusion or osmotic pumps) and upon stagnation in such drug delivery systems. As a part of a series of investigations in this area, the present study investigates the effects of vi...

Since 1980, when the idea of drug-delivery was proposed, various drug-carriers have been developed, including DNA, proteins, liposomes and several other polymer cages, consisting of many well established natural and synthetic nano-particles. All these drug-carriers can self-assemble in the body and can be manipulated for safer delivery into target tissues. By definition, nano-scale drug deliver...

In-vitro labeling of RBC with 99mTc is an intricate procedure and there is always a need foran alternate blood pool imaging agent. The aim of this study was to prepare an effective nanosized liposome (NLs) similar to human RBC for blood pool scintigraphy. This study formulatesPEG-NLs and non-PEG-NLs using film method plus high pressure homogenization technique.Biodistribution studies were perfo...

Free fatty acids and monoglycerides have long been known to possess broad-spectrum antibacterial activity that is based on lytic behavior against bacterial cell membranes. Considering the growing challenges of drug-resistant bacteria and the need for new classes of antibiotics, the wide prevalence, affordable cost, and broad spectrum of fatty acids and monoglycerides make them attractive agents...
