Global gene expression profiles in skeletal muscle of monozygotic female twins discordant for hormone replacement therapy

2010

Summary Aging is accompanied by inexorable loss of muscle tissue. One of the underlying causes for this is the massive change in the hormonal milieu of the body. The role of a female sex steroid – estrogen – in these processes is frequently neglected, although the rapid decline in its production coincides with a steep deterioration in muscle performance. We recruited 54- to 62-year-old monozygotic female twin pairs discordant for postmenopausal hormone replacement therapy (HRT, n = 11 pairs; HRT use 7.3 ± 3.7 years) from the Finnish Twin Cohort to investigate the association of long-term, estrogen-based HRT with skeletal muscle transcriptome. Pathway analysis of muscle transcript profiles r…

Key processing precedes emotional categorization of Western music.

2005

To investigate whether key processing precedes the appraisal of valence in music, participants listened to pairs of clips of same or different valence, played either in the same key or one semitone apart. They judged whether the second clip expressed the same emotion as the first one. Our predictions were confirmed: the response times obtained were shorter when both clips were played in the same key than when they were played one semitone apart.

Structural and Hereditary Chaperonopathies: Mutation

2013

This chapter deals with structural and hereditary chaperonopathies. The chaperonopathies caused by mutations in: sHsp, chaperonin genes (Hsp60 or Cpn60, and CCT subunits), Hsp40/DnaJ, Hsp70, sacsin, and dedicated chaperones (e.g., those involved in microtubule biogenesis, in maintenance of the respiratory chain inside the mitochondria, and others in various cell compartments and tissues), are described and discussed.

Costanti e metamorfosi di un mito. Beatrice Cenci nell'Ottocento, da Shelley a Guerrazzi e oltre.

2011

Il saggio ripercorre la trasformazione in mito letterario della storia di Beatrice Cenci, le la sua straordinaria fortuna nel romanzo e nel teatro europei, con riferimento particolare alla sua presa sulla sensibilità romantica e inoltre al suo ruolo nell'immaginario risorgimentale. The essay deals with the transformation of Beatrice Cenci’ story in a literary myth, with special reference to its impact on the romantic sensitivity, on the collective imagination of Italian Risorgimento, and in the works by Shelley, Stendhal, Dumas and Guerrazzi,

Silybin enhances mitochondrial function and inhibits NFkB activation in murine nonalcoholic fatty liver disease

2010

Italian Journal of Anatomy and Embryology, Vol 115, No 1/2 (Supplement) 2010

2015

The NG2 proteoglycan is characteristically expressed by oligodendrocyte progenitor cells (OPC) and also by aggressive brain tumours highly resistant to chemo- and radiation therapy. Oligodendrocyte-lineage cells are particularly sensitive to stress resulting in cell death in white matter after hypoxic or ischemic insults of premature infants and destruction of OPC in some types of Multiple Sclerosis lesions. Here we show that the NG2 proteoglycan binds OMI/HtrA2, a mitochondrial serine protease which is released from damaged mitochondria into the cytosol in response to stress. In the cytosol, OMI/HtrA2 initiates apoptosis by proteolytic degradation of anti-apoptotic factors. OPC in which NG…

Redox signaling in acute pancreatitis

2015

Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…

Restitutionserscheinungen an pflanzlichen Meristemen nach Röntgenbestrahlung

1964

Young undifferentiated embryos ofEranthis hiemalis were treated with x-rays (1000–4000 r) and their further development was observed. In most of the 4000 r-group the division-activity is completely and irreversibly arrested, but the cell image remains unchanged. The embryos treated with doses between 1000 and 2000 r are also severely damaged, this time undergoing radical disorganization of the tissue, due to degeneration and necrosis. In these embryos small cell groups or even single cells are able to regain their mitotic potency. Meristematic centers (“embryoids”) arise and develop into normal or sometimes misformed viable adventive embryos. This restitution takes place only in x-rayed emb…

Hidden Mediterranean diversity: Assessing species taxa by molecular phylogeny within the opilionid family Trogulidae (Arachnida, Opiliones)

2009

This is the first comprehensive study to evaluate the relationships between the western palearctic harvestman families Dicranolasmatidae, Trogulidae and Nemastomatidae with focus on the phylogeny and systematics of Trogulidae, using combined sequence data of the nuclear 28S rRNA and the mitochondrial cytochrome b gene. Bayesian analysis and Maximum parsimony do not reliably resolve Dicranolasma as distinct family but place it on a similar phylogenetic level as several lineages of Trogulidae. Nemastomatidae and Trogulidae turned out to be monophyletic, as did genera Anelasmocephalus and Trogulus within the Trogulidae. The genera Calathocratus, Platybessobius and Trogulocratus each appeared p…
