Neural markers of a greater female responsiveness to social stimuli
ABSTRACT
Background. There is fMRI evidence that women are neurally predisposed to process infant laughter and crying. Other findings show that women might be more empathic and sensitive than men to emotional facial expressions. However, no gender difference in the brain responses to persons and unanimated scenes has hitherto been demonstrated.
Understanding the molecular process at the basis of polymerization processes of neurotoxic beta-amyloid
Abstract
Understanding the molecular process at the basis of polymerization processes of neurotoxic beta-amyloid can give important contributions for designing new therapies for Alzhemier Disease.
In this perspective, we have performed an in vitro study of the effects on B-amyloid fibrillogenesis of the natural pigment hypericin extracted from Hypericum perforatum (St. John’s worth). Our results show that, thanks to its structural characteristics and peculiar spectroscopic features, hypericin can be easily used to in vitro monitor the appearance of early aggregation states of B-amyloid peptides during the polymerization process and, more importantly, that hypericin can significantly affect and interfere with the early stages of polymerization process, playing the role of an effective aggregation inhibitor.
Acqua alta a Roma: ricostruita al computer la piena del Tevere
Autorità di Bacino del Tevere e CNR nel 2002 hanno simulato al computer gli effetti di un’eventuale esondazione del Tevere e le conseguenze che avrebbe sulle aree urbane di Roma: Ponte Milvio, Prati e Borgo quelle più a rischio
Un torrente d’acqua che inonda Ponte Milvio, prosegue per il Foro Italico, si snoda per Prati fino a lambire Castel Sant’Angelo e il rione Borgo. Una vera e propria catastrofe che si abbatte sulla Capitale, ma per fortuna solo per finta: si tratta infatti di una simulazione molto dettagliata che l’Istituto di Ricerca per la Protezione Idrogeologica (Irpi) del Consiglio Nazionale delle Ricerche (CNR) e Autorità di Bacino del Tevere hanno realizzato nel 2002 per verificare i danni di un simile evento.
Tevere WWF: per i nostri fiumi manca sia il coordinamento che i fondi
Le Autorità di bacino che avrebbero dovuto pianificare la difesa del suolo sul nostro territorio proprio per ridurre il diffuso dissesto idrogeologico sono senza fondi e senza dirigenza.
Tolerable levels for melamine established at a WHO meeting
GENEVA- International experts have established a tolerable daily intake (TDI) for melamine, the implicated chemical found recently in contaminated milk products. The TDI is the outcome of a meeting organized by the World Health Organization (WHO) held this week in Ottawa, Canada to address the issue. The TDI is lower than previous TDIs suggested for melamine by some national food safety authorities.
"We expect this could better guide the authorities in protecting the health of their public," said WHO Director for Food Safety, Dr Jørgen Schlundt, at the closing of the WHO Expert Meeting.

WHO/Bulletin - Young people with HIV taking big risks
GENEVA – Adolescents and young adults with HIV are at high risk of treatment failure and of transmitting the virus to their sexual partners, according to research published today in the international public health journal, the Bulletin of the World Health Organization.
The study, conducted in Haiti, showed that 12 months after beginning therapy, only 106 (73%) of 146 patients were still in medical care (the remainder having died or left therapy) and, of these, only 45% adhered well to life-prolonging antiretroviral treatment, 51% had virologic failure and 73% engaged in unsafe sex. Young people had twice the rate of virologic failure as older patients from the same clinic.
UNESCO and the Kingdom of Bahrain to establish centre for information and communication technology
UNESCO Director-General, Koïchiro Matsuura, and the Minister of Education of the Kingdom of Bahrain, Majed Bin Ali Al Noami, yesterday signed an agreement paving the way for the establishment of a state-of-the-art Centre for Information and Communication Technology to serve the Arab Region.
Voluntary universal annual testing and immediate treatment might have major impact on widespread HIV epidemics
26 November 2008, Geneva — A group of specialists in the World Health Organization (WHO) developed a mathematical model and published findings in the Lancet today to stimulate discussion, debate and further research. The model suggests that using annual, universal voluntary HIV testing followed by immediate ART (irrespective of clinical stage or CD4 count) reduces new cases by 95% within ten years.
Young journalists discussed culture of tolerance at media forum in Saint-Petersburg
The Third European Media Forum for Young Journalists Working for Electronic Media ‘Dialogue of Cultures’ took place from 11 to 12 November 2008 at the State Hermitage Museum in St Petersburg, Russia.
One the biggest museums of the world representing cultural heritage of the humanity gathered over 180 participants from 15 countries. Both young journalists and leading media professionals engaged in an intense dialogue over the key role of the mass media in overcoming stereotypes and fostering a culture of tolerance. Debates focused on emerging challenges of the modern society as well as possibilities of cultural and social exchange. Screening of the video materials brought by the participants boosted the discussions while visits to selected art exhibitions held in the Hermitage Museum provided a perfect background illustration of the Forum’s main theme.
