2. On the molecular mechanism of LHCII proteolysis during photoacclimation of photosystem II
Abstract : Higher plants and green algae have a remarkable ability to respond to fluctuations in the light intensity. Plants adapted to low or high light regimes possess larger or smaller light-harvesting antennae respectively. READ MORE

4. Structural, thermal and thermodynamic properties of some Ln-Pd oxides and their behaviour as catalyst precursors
Abstract : The structural, thermal and thermodynamic properties of some Ln-Pd oxides of the Ln4Pd07 type are presented. The main results are; (i) Reduction of Ln4Pd07, either ex-situ by CO or in-situ by a synthetic car exhaust gas, results in a materialwith catalytic activity for car exhaust gas clean-up reactions.

5. Environmental Contaminants, Recombination and Cancer : Investigations on the molecular mechanisms of spontaneous and induced recombination in the hprt gene of Chinese hamster cells
Abstract : Recombination results in rearrangement of the genetic material contained in the chromosomes inherited from the mother and father and this process is also involved in repairing damage to the genome. Occasionally, the machinery that performs recombination malfunctions and this may lead to illegitimate recombination events which inactivate tumor suppressor genes or activate protooncogenes.
