CAPIRE E GESTIRE LA VIOLENZA NELLA SCHIZOFRENIA

2017

Il problema della violenza nelle persone affette da schizofrenia pone spinosi dilemmi clinici e sociali. Da una parte, il comportamento aggressivo nella schizofrenia può essere una pericolosa, anche se rara, complicanza della malattia. I medici sono tenuti ad anticipare, valutare, gestire e ridurre i rischi di violenza dei loro pazienti, con interventi e trattamenti adeguati. D’altra parte, pazienti psichiatrici capaci di decidere autonomamente, spesso riducono o sospendono il trattamento nel corso del tempo, il che è un loro diritto, e in ogni caso molte cause di violenza non possono essere trattate con i farmaci (Swanson et al., 2008a). Inoltre, concentrarsi semplicemente sul potenziale d…

Anàlisi de la violència filioparental en centres de menors : un estudi monogràfic

2019

espanolAntecedentes: El principal objetivo de este estudio era conocer las caracteristicas sociodemograficas, judiciales y psicologicas de los menores infractores que habian sido denunciados por violencia filio-parental, asi como elaborar posibles perfiles a partir de dichas caracteristicas. Metodo: Se analizaron expedientes judiciales correspondientes a 56 adolescentes del Centro de Educacion e Internamiento por Medida Judicial de Zaragoza –Espana–, que habian sido internados por violencia filio-parental en el periodo comprendido entre 2006 y 2016.Resultados: Los resultados indican una importante presencia de antecedentes por acogimiento en centros de proteccion de menores, hogares familia…

Study of the interactions between Broad bean wilt virus 1 and its host plants

Broad bean wilt virus 1 (BBWV-1) is the type member of the Fabavirus genus, in the Secoviridae family. BBWV-1 is worldwide distributed and infects important horticultural and ornamental crops causing considerable economic losses. However, information about the biological and molecular characteristics of BBWV-1 isolates is scarce. BBWV-1 is composed of two molecules of positive single-stranded RNA (ssRNA+) that are separately encapsidated in virions of icosahedral morphology. Each ssRNA+ encodes polyproteins which are processed by proteolytic cleavage into functional peptides. RNA1 (~ 5.8 kb) encodes for one polyprotein that renders proteins involved in viral replication: a protease cofactor…

Apoptosis in human unfertilized oocytes after intracytoplasmic sperm injection

2005

Objective To investigate the presence of programmed cell death in unfertilized oocytes after intracytoplasmic sperm injection (ICSI), assuming that previous apoptotic events could be correlated with the fertilization failure. Design Comparison of the rate of DNA fragmentation in human oocytes at different stages of maturation soon after pick-up (control) and in unfertilized oocytes after ICSI treatment. Setting In vitro fertilization (IVF) laboratory with extensive ICSI experience. Patient(s) Sixty-three patients undergoing assisted fertilization by ICSI. Intervention(s) Terminal deoxynucleotidyl transferase-mediated digoxigenin-dUTP nick-end labeling (TUNEL) assay and anticaspase-3 cleaved…

Pathogenic mechanisms of how human parvovirus breaks self-tolerance

2017

It is known that viral infections can cause acute, chronic, and autoimmune diseases (ADs). However, the mechanism of how a persistent viral infection contributes to ADs remains still unclear. In this thesis, pathological and immunological aspects of how common viruses can initiate autoimmunity were investigated, and human parvovirus B19 (B19V) was employed as a model virus. B19V non-structural protein 1 (NS1), a superfamily 3 (SF3) helicase, initiated DNA damage resulting in cellular apoptosis. The apoptotic bodies (ApoBods) induced by B19V NS1 were purified and characterized. These ApoBods contained viral NS1 proteins with modified autoimmune-associated self-antigens, e.g. DNA, Smith, Apol…

CHARACTERIZATION OF ATYPICAL CLAVIBACTER MICHIGANENSIS subsp. MICHIGANENSIS POPULATIONS IN GREENHOUSE TOMATOES IN ITALY

2012

The quarantine bacterium Clavibacter michiganensis subsp. michiganensis (Cmm) is the agent of tomato bacterial canker (TBC), one of the most destructive bacterial diseases of this crop, that causes severe economic losses worldwide. During a recent outbreak of TBC in Sicily (insular Italy), it was impossible to amplify the pat-1 gene by PCR with CMM5/CMM6 primers from affected greenhouse-grown plants from three farms, although Cmm-like colonies were consistently isolated. Microlog metabolic profile, 16S rDNA sequencing and the positive amplification of other Cmm DNA targets supported the identification of the strains as Cmm, suggesting the occurrence of a population lacking the virulence gen…

Characterizing the bacterial fish pathogen Flavobacterium columnare, and some factors affecting its pathogenicity

2010

Flavobacterium columnare is a bacterial pathogen of fresh water fish causing lethal columnaris disease worldwide. At Finnish fish farms, columnaris disease has occurred since the early 1980s, and is a serious problem in salmonid farming in Finland. Currently, the only effective treatment is with antibiotics. Factors related to the pathogenicity of F. columnare, transmission of columnaris disease and the immunity of salmonids to columnaris infections are poorly known. F. columnare strains isolated from Finnish fish farms were characterized geno- and phenotypically, virulence and transmission experiments were conducted, and the efficacy of two immunostimulants against columnaris infections in…

Microtubules and microfilaments in HSV-Infected rabbit-kidney cells.

1981

In rabbit kidney cells infected with strains of Herpes simplex virus producing either cell-rounding or polycaryocytosis. Vinblastine induced paracrystals. This could be shown by phase-contrast- and electron-microscopy. Infections were done under one-step-growth conditions or at low MOI. 90 per cent noninfected cells contained stress fibers as detected by Servablue R250-staining. Shortly after recruitment into polycaryocytes, stress fibres of normal length appearing in criss-cross arrangement can be seen in the periphery of these cells. Later they polymerize to very long fibers and finally they are partially destroyed. The time of destruction depends on the MOI employed. By using Actinomycin…

Vaginal infection of mice with HSV type 2 variant ER−: A new animal model for human primary genital HSV type 2 infections

1992

Abstract Studying the pathogenesis of vaginal infections in mice with two variants of Herpes simplex virus type 2 (HSV-2) strain ER we observed that both variants ER+ and ER− caused severe vaginitis but only ER+ invaded the CNS leading to lethal neurological disease. In contrast, mice infected with ER− cleared the virus from the vagina and recovered from infection. ER+ and ER− expressed equal levels of thymidine kinase (TK) indicating a TK-independent difference in neurovirulence. Using the non-neurovirulent variant ER−, we were able to investigate humoral immune responses late after infection. Vaginal infection with ER− suppressed serum antibody formation after a secondary systemic HSV-1 i…
