The present review provides an overview of methods and techniques for studying interactions of micro- and nanoparticulate drug delivery system with mucus. Nanocarriers trapped by mucus are featuring a change in particle size and zeta potential that can be utilized to predict their mucus permeation behavior. Furthermore, interactions between nanoparticulate drug delivery systems and mucus layer ...

The objective of this study was to determine the impact of the learning curve of one surgeon on the term delivery rate following laparoscopic salpingostomy for tubal infertility. This was a retrospective audit of ongoing clinical practice, undertaken in two tertiary level infertility programmes. Subjects in this study were women undergoing surgery for total occlusion of the distal Fallopian tub...

Traditional drug delivery systems which are based on multiple dosing regimens usually pose many disadvantages such as poor compliance of patients and drug plasma level variation. To overcome the obstacles of traditional drug formulations, novel drug delivery system PCL-PEG-PCL hydrogels have been purposed in this study. Copolymers were synthesized by rapid microwave-assisted and conventional sy...

hydrogels are introduced to modem medicine as novel materials suitable for a variety ofbiomedical applications. studying hydrogels as novel biomaterials has become a fast-developingand exciting research field during the last two decades. these interesting biomaterials have found awide range of application including contact lenses, vehicles for drug delivery and scaffold in tissueengineering and...

ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

the increasing incidence of systemic candidiasis, which parallels the use of invasive and immunosuppressive medical procedures, necessitates development of rapid and cost effective tests for diagnosis of systemic candidiasis. therefore in this study 85 mice were first immunosuppressed by cyclophosphamide and then infected by candida albicans ncpf 3153. other 85 mice were employed as control. th...

Intravenous (IV) drug administration is preferable and IV access is quickly and most easily achieved via a peripheral cannula inserted into a large peripheral vein. If there are no visible peripheral veins, the external jugular vein should be considered. Lower limb veins should be avoided due to impairment of venous return below the diaphragm during cardiac arrest. Intravenous drug administrati...
