Although evidence exists that nitric oxide (NO) mediates neuroendocrine secretion in mammals, the involvement of NO in the neuroendocrine regulation of non-mammalian vertebrates has yet to be investigated in detail. The present review conveys several recent data, suggesting that NO plays a modulatory role in the caudal neurosecretory system (CNSS) of(More)
The paper presents a case study based on a system for the monitoring of daily functions in post-stroke rehabilitation patients. The system is capable of monitoring some daily life functions of the patient, by providing to the rehabilitation experts information about the correct or wrong activation of the monitored muscles during those specific functions.(More)
This paper presents the study and realization of a semi-automatic measurement system for the evaluation of the swallowing parameters through the processing of biomedical images, coming from videofluoroscopy. The system has been realized as a software system, developed in JAVA language by means of the ImageJ image processing library. The proposed system is(More)
Spectrum sensing is a key factor for either the development of Cognitive Radio or the implementation of instruments able to automatically monitor the radio spectrum. Within the process of spectrum sensing, segmentation aims to detect the boundaries of the transmission channels in a wide frequency range. The paper proposes a new spectrum segmentation method(More)
The development of the caudal neurosecretory system (CNSS) of the Nile tilapia, Oreochromis niloticus, has been investigated by means of UI/oCRF (urotensin I/ovine corticotropin-releasing factor) immunohistochemistry and transmission electron microscopy. UI-like immunoreactive perikarya and fibers are first detected in the caudal spinal cord of larval fish(More)
The intracellular distribution of neuronal nitric oxide synthase (nNOS) was studied in the caudal neurosecretory system of a teleost, Oreochromis niloticus (Cichlids), by means of post-embedding immunogold labeling with a polyclonal antibody directed against nNOS of human origin. Ultrastructural examination demonstrated that neuronal NOS-like molecules are(More)
Morphological features of the goldfish caudal neurosecretory system were investigated by means of immunohistochemical localization of urotensins I and II (UI and UII) and electron microscopic examination of the caudal neurosecretory neurons, the urophysis, and the synaptic neuropil. The aim of the work is to provide a detailed morphological description of(More)
This study provides evidence that, within the caudal neurosecretory system of the teleost Oreochromis niloticus, neurons express nitric oxide synthase (NOS)-like molecules. The presence of NOS-like molecules was demonstrated by means of NADPH-diaphorase (NADPHd) staining and NOS immunohistochemistry. In the caudal spinal cord, NOS-positive neurosecretory(More)
