Contribution to the elucidation of the anti-inflammatory activity of Sesquiterpene Lactones
… the mechanism by which sesquiterpene lactones (SLs) inhibit DNA binding of the transcription factor NF-kB, the role of cysteine residues in its DNA binding domain was tested using single amino acid mutants of the p65 subunit. The results confirm that p65 is alkylated by SLs, and that the …

Finite element analysis of curl development in the selective laser sintering process
Selective laser sintering (SLS) is a rapid prototyping process, which operates by using a laser to locally heat an area within a layer of powder material, causing it to fuse together, creating a thin cross-section of solid material. 3D shapes are built by repeatedly depositing a layer of fresh …
