6. Biosynthesis and physiological functions of N-acyl amino acids
Abstract : N-acyl amino acids are lipid signalling molecules that have recently been identified in biological systems. These lipids are structurally related to the endocannabinoids, although they do not activate cannabinoid receptors. READ MORE

7. Cellular effects after exposure to mixed beams of ionizing radiation
Abstract : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. READ MORE

8. Post-translational modifications in DNA base excision repair : The roles of CK2 and PARP-1
Abstract : Base lesions and DNA single-strand breaks (SSBs) are very common types of DNA damage. The base excision repair (BER) and single-strand break repair (SSBR) machineries both require a succession of enzymatic events in order to remove these types of endogenous lesions and to restore the DNA.

9. Peptidoglycan regulation of Drosophila immunity
Abstract : Innate immunity is an ancient defense system that distinguishes between self and non self and is present in both vertebrates and invertebrates. Peptidoglycan (PGN), a cell wall component shared by both gram-negative and gram-positive bacteria, is the major recognition molecule for the detection of bacteria in Drosophila. READ MORE

10. Interplay between Transcription and Homologous Recombination in the Presence of DNA Damage
Abstract : The biochemical processes of DNA repair, replication and recombination compete for the same substrate, the DNA molecule. This competition is natural, as each process requires the same template. In order to resolve possible conflicts between these processes, when they take place on a particular stretch of DNA, certain crosstalk is expected. READ MORE
