1. Development and application of advanced electron microscopy techniques for materials in biological systems
Abstract : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. READ MORE

2. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes
Abstract : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. READ MORE

3. Molecular mechanisms of synaptic transmission and plasticity in spinal sensory pathways
Abstract : An intense, potentially tissue-damaging (noxious) stimulus may lead to enhanced pain sensation of subsequent noxious stimuli (hyperalgesia) and to the perceiving of innocuous stimuli as painful (allodynia). This is thought to result to a large extent from strengthening of synapses established by primary afferent fibers onto spinal cord dorsal horn neurons. READ MORE

4. Evaluation of UHT milk processed by direct steam injection and steam infusion technology
Abstract : UHT direct steam injection and steam infusion are widely used; however there is no comparison of their impact on milk components. This study evaluates the structural changes at different steps during the UHT processing of whole milk in a full-scale UHT plant by transmission electron microscopy (TEM) and particle size measurements, and follows the enzymatic activity.

5. Coordination of endocytosis at the synaptic periactive zone
Abstract : Neurons in the central nervous system communicate via specialized junctions called synapses. Neurotransmitter-filled vesicles are clustered at these junctions, where they are released in response to synaptic activity. To sustain reliable neurotransmission the synaptic vesicles are recycled locally. READ MORE
