1. Studies on bacterial transmission pathways in a high endemic area, with a focus on Helicobacter pylori
Abstract : Even though half of the world’s population is infected with Helicobacter pylori, which causes gastritis, peptic ulcer and gastric cancer, the transmission routes of these bacteria remain unknown despite extensive epidemiological studies. Enterotoxigenic Escherichia coli (ETEC) and Vibrio cholerae are two of the most common causes of acute watery diarrhea in developing countries. READ MORE

2. 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

3. Exploring signaling pathways in endothelial mechanotransduction
Abstract : Mechanotransduction, the process by which cells sense and convert mechanical forces from their surroundings, plays a pivotal role in cellular function. For vascular endothelial cells, coping with the continuous and significant shear stress caused by blood flow is essential for the stability of the circulatory system. READ MORE

4. Emerging networks of power: Exploring sociotechnical pathways towards future electricity systems based on renewable energy technologies
Abstract : In the effort to fight climate change, electricity systems around the world are undergoing a transition from fossil-fuelled to renewable energy-based production of electricity. The transition can, however, be attained in several radically different ways, ranging from global or continental super-grids, via local smart-grids, to self-sufficient off-grid communities and households of electricity prosumers.

5. The involvement of degradation pathways and neuron-to-neuron transmission in Alzheimer’s disease
Abstract : Although the vast majority of Alzheimer’s disease (AD) cases are of the sporadic type, mutations causing the familial form have been the focus of AD research for decades. The disease is pathologically characterised by β-amyloid (Aβ) and tau protein aggregates in neuritic plaques and neurofibrillary tangles. READ MORE
