Development of polymeric films embedded with liquid nanodomains.

Modified microemulsions (MEs), termed by us nanodomains (NDs), seem to be suitable vehicles for dermal drug delivery due to their high surface area and the interface enriched with membrane recognizing agents, penetration enhancers, and other components. However, liquid nanodomains do not provide a controlled release of the bioactive through the skin. Therefore, the main goal of our present study is to develop a film polymeric platform embedded with liquid nanovehicles for the controlled release of drugs.

Incorporation of curcumin in liquid nanodomains embedded into polymeric films for dermal application.

Liquid nanovehicles are gaining interest in drug delivery because of the high solubilization capacity of bioactives at their interface and enhanced permeation of compounds across physiological membranes. However, the dermal application of liquid nanovehicles is still limited. The goal of this research is to develop a dermal delivery system based on embedding of liquid nanovehicles into polymeric films, which will allow controlled release of the nanodroplets with the solubilized drug.

Structural Characterization of Reconstituted Bioactive-Loaded Nanodomains after Embedding in Films Using Electron Paramagnetic Resonance and Self-Diffusion Nuclear Magnetic Resonance Techniques.

Pharmaceutical applications of microemulsions (MEs) as drug delivery vehicles are recently gaining scientific and practical interests. Most MEs are able to solubilize bioactive molecules, but, at present, they cannot guarantee either controlled release of the drugs or significant advantage in the bioavailability of the bioactives. This study proposes to incorporate the modified ME structures, or nanodomains, into a natural polymeric film, to be used as a stable and capacious reservoir of drug-loaded nanodomains.

Serum Chromium Levels Are Higher in Peritoneal Dialysis than in Hemodialysis Patients.

An elevation in serum chromium levels in individuals treated with renal replacement therapy has been previously described, but chromium levels have not been systematically studied in patients treated with different dialysis modalities. The aim of this study was to compare serum chromium levels in patients treated with chronic peritoneal dialysis (PD) and hemodialysis (HD).We studied 169 chronic dialysis patients in a single medical center, of which 148 were treated with HD and 21 with PD.

[Management of patients with malignant obstructive jaundice using bile examination after external biliary drainage].

Aim: To determine optimal time of biliary tract decompression and bile reinfusion into gastrointestinal tract in patients with malignant obstructive jaundice.

Material And Methods: 179 medical records of patients with obstructive jaundice were analyzed in order to identify risk factors of postoperative complications. Prospective trial included bile examination in 34 patients with malignant obstructive jaundice.
