1. Phylogenetic and taxonomic studies within Arthonia Ach. (Ascomycetes, Arthoniales)
Abstract : The taxonomy and phylogeny of the genus Arthonia was analysed. As a first step, a phylogenetic analysis was performed to test the monophyly of some of the infrageneric groups suggested by earlier authors. The results strongly support that Arthonia, Arthothelium and Arthoniaceae are paraphyletic. READ MORE

2. Spinal Acetylcholine Release : Mechanisms and Receptor Involvement
Abstract : Impulses coming from peripheries are modified in the spinal cord and transmitted to the brain. Several neurotransmitters have been involved in the processing of impulses in the spinal dorsal horn. Acetylcholine (ACh) is one of many neurotransmitters involved in the regulation of nociception in the spinal cord. READ MORE

3. Regulation by glutamate- and adenosine-receptors of dopamine and acetylcholine release from rat striatal slices
Abstract : The striatum, which is critically involved in sensory motor integration, receives an excitatory glutamatergic input from the cerebral cortex and the thalamus. The effects of the glutamatergic stimulation are modulated by dopamine (DA) released from a prominent dopaminergic input, acetylcholine (ACh) released from cholinergic interneurons and by the ubiquitous neuromodulator adenosine.

4. Modulation of acetylcholine release by serotonergic 5-HT1A and 5-HT1B receptors : a microdialysis study in the awake rat
Abstract : The aim of the thesis was to investigate the effects of the 5-HT1A receptor antagonist robalzotan (NAD-299) and the 5-HT1B receptor antagonist NAS-181 ((R)-(+)-2-(3-morpholinomethyl-2Hchromen-8-yl) oxymethyl-morpholine methanesulfonate) on cholinergic, glutamatergic and GABAergic neurotransmission in the rat brain in vivo. The extracellular levels of acetylcholine (ACh), glutamate (Glu) and GABA were monitored by microdialysis in the frontal cortex (FC) and ventral hippocampus (VHipp) in separate groups of awake rats.

5. Neuropeptides and neurotransmitters in keratocytes : importance in corneal wound healing processes
Abstract : Background: The cornea is the outermost transparent layer of the eye and it is responsible for the majorityof the eye’s total focusing power. Keratocytes are the resident cells of the corneal stroma and their function isto produce extracellular matrix components and to take part in corneal healing after injury, which may occurdue to trauma, infection or surgery.
