1. Catabolism of Pyrimidines in Yeast
Abstract : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. READ MORE

2. Impact of autocrine factors on physiology and productivity in Trichoplusia ni serum-free cultures
Abstract : The aim of this study was to increase the understanding of the mechanisms regulating cell proliferation and recombinant protein production in serum-free cultures of Trichoplusia ni (T. ni) insect cells.Conditioned medium (CM) was shown to contain both stimulatory and inhibitory factors (CM factors) influencing cell growth.

3. PCR-based detection of microorganisms in complex biological samples
Abstract : The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. READ MORE

4. Nutritional Limitations of a Green Protein Shift with Focus on Iron
Abstract : A dietary shift into plant-based diets (PBD) to reduce the climate footprint is advocated. Effects on nutrition and health from a modern PBD, composed of replacement products based on protein extracts are however currently unknown. READ MORE

5. Activation of human dendritic cells : role of the allergenic yeast Malassezia and NK cells
Abstract : Immature bone marrow derived dendritic cells (DCs) patrol the periphery of our body, where they encounter and take up foreign antigens. Once activated, DCs migrate to regional lymph nodes to present peptides derived from these antigens to naive T cells, and elicit different T helper (Th) cell responses. READ MORE
