1. Design of solid dosage forms for mucosal vaccination - Investigations on the influence of excipients on product performance
Abstract : Most vaccines today are liquid formulations for parental administration. However, there are several drawbacks connected to these vaccines. Since injectable vaccines only induce systemic antibody responses, they are not effective against the various pathogens that affect mucosal surfaces with poor permeability for serum-derived antibodies, e.g. READ MORE

2. Skin hydration - How water and osmolytes influence biophysical properties of stratum corneum
Abstract : The outermost layer of skin (i.e., the stratum corneum, SC) is the interface that separates the water-rich inside of the body from the relatively dry external environment. SC forms an effective permeability barrier, which has to be overcome in transdermal drug delivery. READ MORE

3. Hydrolytic degradation of dental composites and effects of silane-treatment and filler fraction on compressive strength and thermal expansion of composites
Abstract : Some researchers have suggested that the weakest link of dental composites is the filler-matrix bond. However, due to incompleteness of information dealing with this bond and its stability in a humid environment, it was considered desirable to investigate the effect of water on this region, as well as the influence of filler bonding and filler fraction on compressive strength and thermal expansionExperimental composites containing different filler fractions of either silane-treated or untreated fillers were made.

4. Blood pressure-dependent changes in plasma volume, glycocalyx and platelet function during anaesthesia -Clinical and experimental studies
Abstract : Background: Worldwide, more than 300 million surgeries are performed each year. General anaesthesia provides the surgical patient with a state of controlled loss of sensation and awareness. It is common that general anaesthesia causes hypotension. Anaesthesia-induced hypotension is associated with haemodilution and increased plasma volume (PV). READ MORE
