1. Contribution of polyfluoroalkyl phosphate esters (PAPs) and other precursor compounds to perfluoroalkyl carboxylates (PFCAs) in humans and the environment
Abstract : Per-and polyfluoroalkyl substances (PFAS) are anthropogenic compounds that have been spread all over the world. The use of fluorotelomer compounds, short-chained homologues, and other PFASs with perfluorinated moieties has emerged recent years. READ MORE

2. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure
Abstract : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. READ MORE

3. Cellular design of heparan sulfate : The NDST enzymes and their regulation
Abstract : Heparan sulfate proteoglycans are proteins with long, unbranched heparan sulfate (HS) polysaccharide chains attached to them. They are found on cell surfaces and in basement membranes where they exert their action by interacting with a wide range of enzymes and signaling molecules and are thereby involved in a range of various processes both during embryonic development and in adult physiology.

4. Functional Significance of Multiple Poly(A) Polymerases (PAPs)
Abstract : 3’ end cleavage and polyadenylation are important steps in the maturation of eukaryotic mRNAs. Poly(A) polymerase (PAP), the enzyme catalysing the addition of adenosine residues, exists in multiple isoforms. In this study the functional significance of multiple poly(A) polymerases have been investigated. READ MORE

5. Cellular regulation of heparan sulfate structure and function
Abstract : Heparan sulfate (HS) is a sulfated glycosaminoglycan found on cell surfaces and in the extracellular matrix as HS proteoglycans. HS is synthesized as a polymer of alternating glucuronic acid and N-acetylglucosamine units. READ MORE
