Legami in diaspora. Figli e madri nell'emigrazione dalla Romania
No full textQuando le madri lasciano il proprio Paese e vanno a lavorare altrove, spesso si trovano a dover affidare le cure, l’accudimento, la presenza che altrimenti riserverebbero ai propri figli ad altri, anche a chi è estraneo alla famiglia. Appare facile, in questi casi, giudicarle come madri egoiste e disattente, e colpevolizzarle per aver disatteso i propri ruoli di genere. Soprattutto quando le donne tornano malate di quella che è conosciuta oggi come ‘Sindrome Italia’. In questa ricerca tra Friuli e Moldavia, vengono esaminati i modi per creare e mantenere i legami in diaspora, dal punto di vista delle madri, ma soprattutto dei bambini e degli adolescenti. Tra Italia e Romania, Felicia Ciobanu, Egidiu Condac, Donatella Cozzi, Marco Fontana e Alessandro Zuliani propongono una serie di riflessioni intorno a chi parte, chi resta e chi torna per dare respiro alle singole storie di lontananza e abbandono
Presence and distribution of LHRH- and alpha-MSH-like immunoreactive nerve fibers in the epithalamus of the sheep.
No full textThe presence of luteinizing-hormone-releasing hormone (LHRH)-like and alpha-melanocyte-stimulating hormone (alpha-MSH)-like immunoreactive fibers, nerve terminals or cellular elements in the pineal gland of the sheep has been investigated by immunohistochemistry. No LHRH-or alpha-MSH-like immunoreactive fiber, nerve terminals or cellular elements have been demonstrated in the pineal organ of the sheep. However, LHRH- and alpha-MSH-like immunoreactive fibers are present in the posterior commissure. Immunoreactive LHRH and alpha-MSH nerve endings are evident in the medial and lateral habenular nuclei. Discrepancies with the results obtained in other mammals are indicative of species differences in the distribution of LHRH- and alpha-MSH-like immunoreactive material in the pineal region

Cell types in the pineal gland of the horse: an ultrastructural and immunocytochemical study.
No full textA combined ultrastructural and immunocytochemical study was performed on the pineal gland of the horse in order to identify the cell types present and describe their characteristics. Comparisons have been made with other mammals. Two main cell types are present: pinealocytes and glial cells. Pinealocytes display different degrees of electron density in the nucleus and the cytoplasm, yet no ultrastructural feature supports the idea of separate populations. Putative secretory materials are stored in vesicles related to the Golgi apparatus. A variety of electron-dense bodies are present in the cytoplasm. Interstitial cells responding to anti-GFAP (glial fibrillary acid protein) and anti-vimentin antibodies, but not to anti-neuronal 200-kD protein antibodies, are located close to the perivascular spaces and connective septa. Morphological and immunocytochemical features support classifying them as astrocytes, probably protoplasmic. The presence of a cavity lined with pericytes, putatively a remnant of the embryonic lumen of the organ, is a consistent finding and may relate to the third ventricle

No full textVIPergic innervation of the mammalian pineal gland
No full textThe present article reviews the literature relative to VIP- and PHI-containing nerve fibers in the pineal gland of mammals. The article summarizes data on the presence and distribution of the two peptides in the brain of mammals, their role in neuronal metabolism, and the significance and origin of VIPergic and PHIergic cerebrovascular nerve fibers. Special emphasis is placed on VIP- and PHI-containing nerves in the pineal gland. The morphology of the fibers, the nature of the innervation, and the distribution of immunoreactive nerves within the pineal gland are examined. The review discusses the nature of the classical and "central" innervation of the pineal gland. The possible site of origin of pinealopetal VIPergic and PHIergic fibers is investigated, with special reference to ganglia of the head, and particularly to the pterygopalatine, otic, and trigeminal ganglia. The nature of VIP (and PHI) receptors is examined with reference to the most recent acquisitions in the field. Based on the data, a role for VIP (and PHI) in pineal metabolism is discussed
The protein-phosphatase inhibitor okadaic acid mimics MSH-induced and melatonin-reversible melanosome dispersion in Xenopus laevis melanophores
No full textThe present study describes the ability of 315 nM okadaic acid to induce melanosome dispersion in cultured Xenopus laevis melanophores. This effect of okadaic acid is similar to that of a-melanocyte stimulating hormone (MSH) and can be reversed by melatonin treatment; it indicates that a member of the protein-phosphatase 1 or 2A families must be active for maintenance of the aggregated state. Higher concentrations of okadaic acid (1 microM) attenuate the response of Xenopus melanophores to melatonin leading to the hypothesis that melatonin action is mediated by the calcium/calmodulin activated phosphatase 2B. This hypothesis seems unlikely, however, since the calcium/calmodulin inhibitors TFP and W7 do not prevent melatonin-induced pigment aggregation, but instead induce aggregation on their own
Finance and investment in the Eurozone
No full textThis chapter reviews some of the core constraints that have developed in the Eurozone on investment and growth as a result of the shift towards economic liberalism. The chapter also advances some alternative policies for promoting growth and investment. The chapter starts with a review of the impact of financial liberalization on investment and growth in the Eurozone and of the Eurozone fiscal policy stance on investment and growth. In light of this background, Cozzi puts forward some progressive economic policies for growth and investment in the Eurozone
