Amino acid (aa) neurotransmitters in synaptic afferents to hypothalamic GnRH-I neurons are critically involved in the neuroendocrine control of reproduction. Although in rodents the major aa neurotransmitter in these afferents is γ-aminobutyric acid (GABA), glutamatergic axons also innervate GnRH neurons directly. Our aim with the present study was to(More)
Bioassay guidance was used along the whole process including method development, isolation and identification of antibacterial neem (Azadirachta indica) oil compounds. The biomonitoring was performed by direct bioautography (DB), a combination of thin-layer chromatography (TLC) and antimicrobial detection. DB of neem oil showed one antibacterial zone that(More)
Local biomechanical effects play an important role in aneurysm formation and rupture. It is hypothesised that the main governing factors of the pathogenetic process are the temporal variation and spatial distribution of the flow induced wall shear stress (WSS). The present paper investigates the geometry of the carotid bifurcation, a typical location of(More)
We aim to introduce a novel, inverse method for in vivo material parameter identification of human abdominal aortic aneurysms (AAA), which could overcome one of the greatest sources of uncertainty in patient-specific simulations, and could also serve as a rapid, patient-calibrated, novel measure of aneurysm rupture risk. As an initial step, the(More)
