1. Probing intestinal permeability in man using different-sized, low-molecular-weight polyethyleneglycols and mathematical modelling
Abstract : Selective intestinal permeability as reflected by the urinary recovery of low-molecular-weight polyethylene glycols (PEG 400) of dlfferentsizes after oral administration was characterized with a mathematical filter-function. There was relative loss of both large and small PEG molecules on their way from the intestine to the urine. READ MORE

2. Particle interactions and internal tablet structure : Factors affecting the mechanical strength of pharmaceutical compacts
Abstract : A simple tablet model was utilised to identify parameters responsible for tablet compactibility. In this model tablets were considered as homogeneous and isotropic aggregates of individual spherical particles. If the particles were located close enough to each other, interparticulate bonds were assumed to be developed. READ MORE

3. Properties of stabilizers in colloidal dispersions
Abstract : Surfactants and polymers are frequently used as stabilizers in colloidal dispersions. Depending on their solubility and the interactions in their local environment, their tendency to remain adsorbed on a surface will differ. READ MORE

4. Growth and integrity of the small intestine in malnutrition and trauma
Abstract : The small intestine is an active metabolic organ constituting a functional and immunologic barrier to toxins and microbes in the intestinal lumen. Injuries are repaired by rapid cell replication, which depends on nutritional and humoral growth factors. Glutamine has been suggested to be the most important nutrient for the enterocytes. READ MORE

5. Characterisation of Aqueous Solutions, Liquid Crystals and Solid State of Non-ionic Polymers in Association with Amphiphiles and Drugs
Abstract : Cellulose ethers and polyethylene glycols are used in drug formulations as water swelling or water soluble matrices. Polar lipids, for example monoglycerides, and surfactants can be used to solubilise hydrophobic or amphiphilic drugs and to formulate potential drug delivery vehicles such as emulsions, liposomes and cubic phases.
