1. Boning up on Vitamin D : Observational Studies on Bone and Health
Abstract : The primary function of vitamin D in humans is to maintain sufficient circulating calcium concentrations. Low vitamin D levels could result in excessive calcium resorption from bone. Vitamin deficiency may therefore decrease bone mineral density (BMD), resulting in an increased risk of fracture. READ MORE

2. Mechanism of conditional repression of human osteocalcin gene activity by glucocorticoids
Abstract : Bone is one of the major target sites of steroid hormone action. Steroid hormones like cortisol, vitamin D and estradiol are responsible for principle events associated with bone formation and resorption. READ MORE

3. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies
Abstract : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. READ MORE

4. The structure and conformation of saccharides determined by experiment and simulation
Abstract : A computer program, CASPER, for sequence determination of oligosaccharides and regular polysaccharides using NMR-data, has been extended to support multiply branched structures. The program has been modified to allow the use of incomplete experimental data since spectral overlap can be a problem even at high fields. READ MORE

5. Development of biocatalytic processes for selective antioxidant production
Abstract : Feruloyl esterases (FAEs, EC 3.1.1.73) represent a subclass of carboxylic acid esterases that under normal conditions catalyze the hydrolysis of the ester bond between hydroxycinnamic acids (ferulic acid, sinapic acid, caffeic acid, p-coumaric acid) and sugar residues in plant cell walls.
