1. Aspects of the human enteric nervous system : A study of the normal development and of Hirschsprung's disease
Abstract : Thirty patients with Hirschsprung's disease (HD) who underwent Rehbein's anterior resection, using a circular stapler to perform the anastomosis, were evaluated retrospectively. The postoperative complication rate and long-term functional outcome were similar to those reported by other investigators using the same and other techniques. READ MORE

2. Odour detection in the desert locust, Schistocerca gregaria: antennal structure and function
Abstract : The desert locust, Schistocerca gregaria, is a polymorphic insect that occurs in two morphological and physiological distinct phases, solitary and gregarious, depending on population density. The two phases are reversible at any developmental stage. The gregarious phase produces and uses stage-specific pheromones, that keep the swarm together. READ MORE

3. Identification of novel Wnt/PCP signaling regulators and their role in midbrain dopaminergic neuron development and Parkinson's disease
Abstract : Wnt signaling controls a wide spectrum of complex cell responses during prenatal development, in the adulthood and during disease. In this doctoral study, we have identified and explored novel regulatory components of Wnt/Planar Cell Polarity (PCP) pathway and their function in various cellular processes during embryogenesis and central nervous system (CNS) development.

4. Photoreceptor degeneration, second order neuron remodeling and glia reactivity in an in vivo and in vitro model of retinal neurodegeneration
Abstract : Photoreceptors have the ability to last during the entire lifespan of an individual. Being the first line of neurons in the visual transduction pathway, their health and maintenance is eminent for proper retinal function. However, photoreceptors are susceptible to neurodegenerative retinal dystrophies. READ MORE

5. Wnt signalling in the development of ventral midbrain dopaminergic neurons
Abstract : Dopaminergic (DA) neurons in the ventral midbrain (VM) are one of the major cell types lost in Parkinson's disease (PD). Proof-of-principle exists for cell replacement therapies for PD, but wider application is halted by the unavailability of abundant sources of DA neurons. Stem cells might constitute one of these sources. READ MORE
