1. ATP-Binding Cassette Efflux Transporters and Passive Membrane Permeability in Drug Absorption and Disposition
Abstract : Transport into and across the cells of the human body is a prerequisite for the pharmacological action of drugs. Passive membrane permeability and active transport mechanisms are major determinants of the intestinal absorption of drugs, as well as of the distribution to target tissues and the subsequent metabolism and excretion from the body.

2. A Passive Sampling System for Monitoring Metals in the Aquatic Environment
Abstract : Water monitoring is undertaken routinely as a requirement of water quality legislation. It is usual that water monitoring is undertaken through spot sampling. A passive sampling system has been developed for the aquatic environment that provides time-averaged (integrated) concentrations for metals. READ MORE

3. Atomic Spectroscopy on Fusion Relevant Ions and Studies of Light Impurities in the JET Tokamak
Abstract : The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. READ MORE

4. Lattice Boltzmann simulations of tracer diffusion in microswimmer suspensions
Abstract : Suspensions of microswimmers are a class of systems inherently out of equilibrium, due to the mechanical work continuously performed by a large number of active agents. Biological examples are plentiful, as many aquatic microorganisms have the ability to propel themselves. READ MORE

5. ALA and m-ALA in bicontinuous lipid formulations: -Characterization and Transdermal Delivery
Abstract : δ-Aminolevulinic acid (ALA) and its methyl ester (m-ALA) are both used in photodynamic therapy (PDT) of certain non melanoma skin cancers as the basal cell carcinoma (BCC). In PDT the cancer cells are destroyed by a photochemical reaction that occurs when a photosensitive molecule is irradiated with light of a certain wavelength. READ MORE
