Translating Academic Drug Discovery Into Clinical Development: A Survey of the Awareness of Regulatory Support and Requirements Among Stakeholders in Europe.

Important discoveries by academic drug developers hold the promise of bringing innovative treatments that address unmet medical needs to the market. However, the drug development process has proved to be challenging and demanding for academic researchers, and regulatory challenges are an important barrier to implementing academic findings in clinical practice. European regulators offer varying degrees of support services to help drug developers meet regulatory standards and requirements.

How do Twitter users react to TV broadcasts dedicated to vaccines in Italy?

Background: Social media monitoring during TV broadcasts dedicated to vaccines can provide information on vaccine confidence. We analyzed the sentiment of tweets published in reaction to two TV broadcasts in Italy dedicated to vaccines, one based on scientific evidence [Presadiretta (PD)] and one including anti-vaccine personalities [Virus (VS)].

Methods: Tweets about vaccines published in an 8-day period centred on each of the two TV broadcasts were classified by sentiment.

Investigating paternal preconception risk factors for adverse pregnancy outcomes in a population of internet users.

Background: Paternal preconception risk factors such as smoking, exposure to environmental substances, medication use, overweight and advanced age correlate with the occurrence of malformations and birth defects in the offspring. Nonetheless, the prevalence of risk factors for adverse pregnancy outcomes in the male population has been scarcely investigated and no report on preconception interventions targeting prospective fathers is available. We conducted a web-based survey to measure the prevalence of paternal preconception risk factors for adverse pregnancy outcomes in an Italian population of Internet users.

Web-based surveillance of public information needs for informing preconception interventions.

Background: The risk of adverse pregnancy outcomes can be minimized through the adoption of healthy lifestyles before pregnancy by women of childbearing age. Initiatives for promotion of preconception health may be difficult to implement. Internet can be used to build tailored health interventions through identification of the public's information needs.

Women participating in a web-based preconception study have a high prevalence of risk factors for adverse pregnancy outcomes.

Background: Adverse pregnancy outcomes (APOs) can be increased by preconception risk factors and lifestyles.We measured the prevalence of preconception risk factors for APOs in a population of Italian women of childbearing age enrolled in a web-based study.

Methods: Participants were enrolled through a web platform (http://www.

A cohort study of a tailored web intervention for preconception care.

Background: Preconception care may be an efficacious tool to reduce risk factors for adverse pregnancy outcomes that are associated with lifestyles and health status before pregnancy. We conducted a web-based cohort study in Italian women planning a pregnancy to assess whether a tailored web intervention may change knowledge and behaviours associated with risks for adverse pregnancy outcomes.

Methods: The study was entirely conducted on the web on a cohort of Italian women of childbearing age.

Attitude of Italian physicians toward pertussis diagnosis.

Resurgence of pertussis has been observed in several countries whereas Italy continues to be a low incidence country. We hypothesize that the low reported incidence of pertussis in Italy could be biased by the attitude of physicians to suspect and diagnose pertussis in different age groups. We investigated the attitude of Italian physicians toward pertussis diagnosis through clinical scenarios.

The internet user profile of Italian families of patients with rare diseases: a web survey.

Background: The use of the Internet for searching and sharing health information and for health care interactions may have a great potential for families of children affected with rare diseases. We conducted an online survey among Italian families of patients with rare diseases with the objective to describe their Internet user profile, and to explore how Internet use affects their health decisions.

Methods: All members of UNIAMIO FIMR, a federation of associations of patients with rare diseases, were invited via mail to participate in an online questionnaire including questions on socio-demographic and clinical information, Internet use with a specific focus on health, and impact of web information on health behaviors.

Does googling for preconception care result in information consistent with international guidelines: a comparison of information found by Italian women of childbearing age and health professionals.

Background: Preconception counseling is effective in reducing the risk of adverse pregnancy outcomes. The Internet is commonly used by women and health professionals to search for health information. We compared the consistency of preconception information found on the Internet with the recommendations published by American Journal of Obstetrics and Gynecology (AJOG) simulating a web search by women of childbearing age and health professionals.

Recruitment of TIF1γ to chromatin via its PHD finger-bromodomain activates its ubiquitin ligase and transcriptional repressor activities.

The interplay between sequence-specific DNA-binding transcription factors, histone-modifying enzymes, and chromatin-remodeling enzymes underpins transcriptional regulation. Although it is known how single domains of chromatin "readers" bind specific histone modifications, how combinations of histone marks are recognized and decoded is poorly understood. Moreover, the role of histone binding in regulating the enzymatic activity of chromatin readers is not known.

A translational signature for nucleosome positioning in vivo.

In vivo nucleosomes often occupy well-defined preferred positions on genomic DNA. An important question is to what extent these preferred positions are directly encoded by the DNA sequence itself. We derive here from in vivo positions, accurately mapped by partial micrococcal nuclease digestion, a translational positioning signal that identifies the approximate midpoint of DNA bound by a histone octamer.

H4 acetylation does not replace H3 acetylation in chromatin remodelling and transcription activation of Adr1-dependent genes.

Histone acetylation regulates gene expression. Whether this is caused by a general increase in nucleosome fluidity due to charge neutralization or by a more specific code is still matter of debate. By using a set of glucose-repressed Adr1-dependent genes of Saccharomyces cerevisiae, whose transcription was previously shown to require both Gcn5 and Esa1, we asked how changes of histone acetylation patterns at the promoter nucleosomes regulate chromatin remodelling and activation.

Histone acetylation in gene regulation.

Genetic information is packaged in the highly dynamic nucleoprotein structure called chromatin. Many biological processes are regulated via post-translational modifications of key proteins. Acetylation of lysine residues at the N-terminal histone tails is one of the most studied covalent modifications influencing gene regulation in eukaryotic cells.

The ISWI and CHD1 chromatin remodelling activities influence ADH2 expression and chromatin organization.

Nucleosome remodelling complexes play a key role in gene activation in response to environmental changes by driving promoter chromatin to reach an accessible configuration. They also mediate genome-wide chromatin organization, although their role in processes other than activation-related chromatin remodelling are poorly understood. The Saccharomyces cerevisiae ADH2 gene represents an excellent model for understanding the role of chromatin structure and remodelling in gene regulation.

Common chromatin architecture, common chromatin remodeling, and common transcription kinetics of Adr1-dependent genes in Saccharomyces cerevisiae.

The chromatin structure of several Saccharomyces cerevisiae ADR1-dependent genes was comparatively analyzed in vivo in order to evaluate the role of promoter architecture in transcriptional control. In repressing conditions (high glucose) a nucleosome particle always obstructs the TATA box, immediately adjacent to an upstream-located nucleosome-free region containing a cluster of Adr1 binding sites. Upon derepression the TATA box-containing nucleosome is destabilized according to a mechanism shared by all of the genes studied.
