Download or read book Histaminergic neurotransmission as a gateway for the effects of the fat sensing molecule Oleoylethanolamide written by Alessia Costa and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The histaminergic system is a pleiotropic system that commands general states of metabolism and consciousness, including learning and memorizing both pleasurable and aversive events. Brain histamine mediates the central effects of a signal molecule produced in the intestine, namely oleoylethanolamide (OEA). OEA is released by the enterocytes in response to high fat intake and reduces eating, by indirectly activating a subpopulation of histaminergic neurons. In her thesis, she explored other potential interactions between these two systems in the pursuit of unexplored neuronal mechanisms that may shed light on the mode of action of psychoactive agents and possibly lead to the development of new drugs.
Download or read book Advanced Ground Based Real and Synthetic Aperture Radar written by Lapo Miccinesi and published by Firenze University Press. This book was released on 2022 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground-based/terrestrial radar interferometry (GBRI) is a scientific topic of increasing interest in recent years. The GBRI is used in several field as remote sensing technique for monitoring natural environment (landslides, glacier, and mines) or infrastructures (bridges, towers). These sensors provide the displacement of targets by measuring the phase difference between sending and receiving radar signal. If the acquisition rate is enough the GBRI can provide the natural frequency, e.g. by calculating the Fourier transform of displacement. The research activity, presented in this work, concerns design and development of some advanced GBRI systems. These systems are related to the following issue: detection of displacement vector, Multiple Input Multiple Output (MIMO) and radars with 3D capability.
Download or read book Isotopic fractionation study towards massive star forming regions across the Galaxy written by Laura Colzi and published by Firenze University Press. This book was released on 2022 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important tools to investigate the chemical history of our Galaxy and our own Solar System is to measure the isotopic fractionation of chemical elements. In the present study new astronomical observations devoted to the study of hydrogen and nitrogen fractionation (D/H and 14N/15N ratios) of molecules, towards massive star-forming regions in different evolutionary phases, have been presented. Moreover, a new detailed theoretical study of carbon fractionation, 12C/13C ratios, has been done. One of the main results was the confirmation that the 14N/15N ratio increases with the galactocentric distance, as predicted by stellar nucleosynthesis Galactic chemical evolution models. This work gives new important inputs on the understanding of local chemical processes that favor the production of molecules with different isotopes in star-forming regions.
Download or read book Functional validation of genetic variants identified by next generation sequencing in malformations of cortical development written by Dalila De Vita and published by Firenze University Press. This book was released on 2022 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malformations of cortical development (MCDs) result from a disruption in the process of the human brain cortex formation: currently, there are no pharmacological treatments for diffuse MCDs. Next-generation sequencing has accelerated the identification of MCDs causing genes: in some cases, functional studies are needed to clarify the role of genetic variants. The aim of this PhD project has been to apply a multidisciplinary approach to identify causative mutations in patients with MCDs, validate the pathogenic role of the identified mutations, and assess the effectiveness of novel in vitro treatment for mTOR pathway related MCDs.

This book was released on 2022 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work the central area of Corsica island was studied in order to reconstruct the tectono-metamorphic history of the continental and oceanic high pressure units that occupy the structurally deeper levels of the tectonic stacking of Alpine Corsica and their stratigraphic and structural relationship with the European margin (Hercynian Corsica). The study includes the geological mapping, the mesoscale and microscale structural analysis, the acquisition of chemical analyzes and micromaps with the microprobe, thermobarometric estimation through specific methodologies for metapelites, U-Th-Pb dating of zircons and allanites. The results obtained allows to reconstruct the geodynamic model of this sector of the Alpine belt from the Permian to the Burdigalian.
Download or read book Histamine in the brain written by Jian-Sheng Lin and published by Frontiers Media SA. This book was released on 2015-03-18 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain aminergic pathways are organized in parallel and interacting systems, which support a range of functions, from homoeostatic regulations to cognitive, and motivational processes. Despite overlapping functional influences, dopamine, serotonin, noradrenaline and histamine systems provide different contributions to these processes. The histaminergic system, long ignored as a major regulator of the sleep-wake cycle, has now been fully acknowledged also as a major coordinator of attention, learning and memory, decision making. Although histaminergic neurons project widely to the whole brain, they are functionally heterogeneous, a feature which may provide the substrate for differential regulation, in a region-specific manner, of other neurotransmitter systems. Neurochemical preclinical studies have clearly shown that histamine interacts and modulates the release of neurotransmitters that are recognized as major modulators of cognitive processing and motivated behaviours. As a consequence, the histamine system has been proposed as a therapeutic target to treat sleep-wake disorders and cognitive dysfunctions that accompany neurodegenerative and neuroinflammatory pathologies. Last decades have witnessed an unexpected explosion of interest in brain histamine system, as new receptors have been discovered and selective ligands synthesised. Nevertheless, the complete picture of the histamine systems fine-tuning and its orchestration with other pathways remains rather elusive. This Research Topic is intended to offer an inter-disciplinary forum that will improve our current understanding of the role of brain histamine and provide the fundamentals necessary to drive innovation in clinical practice and to improve the management and treatment of neurological disorders.

Download or read book Use of Microorganisms in the Removal of Pollutants from the Wastewater written by Giovanni Colica and published by Firenze University Press. This book was released on 2009 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aims of this thesis were to test the adsorption efficiency of cyanobacterial biomasses of polysaccharide producing strains and to realize a pilot plant for galvanic waste treatment based on biosorption. First of all the different strains were tested at laboratory scale with solutions containing one or more metals, in order to gradually approach the reality of galvanic industries, where several metals at different concentrations are present at the same time in the wastes. To realize the pilot plant we tried to combine the protocols established during laboratory experiments with the necessities of the final user, the industry, by designing and realizing three prototypes. It was moreover evaluated the possibility to recover the adsorbed metal in a form easy and convenient for recycling.
Download or read book Determinants of Mobility Disability in Older Adults Evidence from Population Based Epidemiologic Studies written by Marco Inzitari and published by Firenze University Press. This book was released on 2010 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gait and mobility are cardinal to maintain autonomy and independency in daily life, also for older persons. Changes in these functions might be critical in the transition towards disability and loss of autonomy during the aging process. The aim of the present work, which collects three years of research conducted between Italy and the United States, was to assess some of the main risk factors for the progressive impairment of mobility and gait in older adults living in the community. According to our results, abnormalities in the nervous and cardiovascular systems, even subtle, are associated with a subsequent worsening of these functions. These data might help to better understand the progressive development of disability in the elderly, and in the future might also have practical implications for prevention.
Download or read book Sub Wavelength Probing and Modification of Complex Photonic Structures written by Silvia Vignolini and published by Firenze University Press. This book was released on 2010 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis consists in the study and modification of complex photonic nano-structures. Nowadays, propagation of light in such materials is a rich and fascinating area of research, both for its fundamental implications and for its practical technological impact. To deeply investigate light propagation inside these structures a high spatial resolution technique is required, especially because intriguing effects often occur on length scales comparable with the diffraction-limit or involve coupling phenomena on this length scale. For this reason in this thesis a Scanning Near-Field Optical Microscope represents one the most straightforward tool both to study and locally modify complex photonic nano-structures from perfect periodic to completely random ones.

In this book, we tackle this problem by exploiting social network contributions. A comprehensive treatise of three linked problems on image annotation is presented, with a novel experimental protocol used to test eleven state-of-the-art methods. Three novel approaches to annotate, under stand the sentiment and predict the popularity of an image are presented. We conclude with the many challenges and opportunities ahead for the multimedia community.
Download or read book Hydrogen production using Purple Non Sulfur Bacteria PNSB cultivated under natural or artificial light conditions with synthetic or fermentation derived substrates written by Alessandra Adessi and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis was to verify the feasibility of the hydrogen production process with purple non sulfur bacteria both under sunlight irradiation in an up-scaled system and with the use of low cost substrates. Among the products offermentations tested the best results were obtained with a medium derived from vegetable wastes. The use of a genetically modified strain of Rhodopseudomonas palustris insensitive to ammonium opened the way towards the use of wastes with attainment of high hydrogen yields also in inhibiting conditions. The experimentation carried out under natural irradiation demonstrated the full feasibility of the process using sunlight instead of artificial light in a semi-pilot reactor: the production rates were the highest so far reported for comparable outdoor systems.
