Further spread of West Nile virus in Italy.

2010

Following two consecutive years of West Nile virus (WNV) circulation in Italy, new foci of infection were observed in August 2010 in Sicily and Molise in southern and central Italy, respectively. These incidents were far from the previous infected area in northern Italy, thereby confirming the ability of WNV to spread to new areas and affect new host populations. © Istituto G. Caporale 2010.

Adoption of digital innovations in rural enterprises during COVID-19

2021

The COVID-19 pandemic has rapidly affected the operating conditions of enterprises. Traditional customers and operational models are changing radically in the short term. Digitalisation and digital methods provide an opportunity to re-organise working methods and create a new kind of business to replace old methods and business models. Compared to urban enterprises, rural enterprises have less experience with digital tools and are less likely to adopt digital innovations. This makes rural enterprises especially vulnerable. The purpose of this study is to provide insights into how micro-enterprises and small and medium-sized enterprises in rural areas have addressed the COVID-19 pandemic, th…

Stay at Home and Teach: A Comparative Study of Psychosocial Risks Between Spain and Mexico During the Pandemic

2020

Context The emergency situation caused by coronavirus disease 2019 (COVID-19) has affected different facets of society. Although much of the attention is focused on the health sector, other sectors such as education have also experienced profound transformations and impacts. This sector is usually highly affected by psychosocial risks, and this could be aggravated during the current health emergency. Psychosocial risks may cause health problems, lack of motivation, and a decrease of effectiveness at work, which in turn affect the quality of teaching. Despite their importance, there are hardly any studies that analyze psychosocial risks of non-university teachers during a health emergency su…

Norovirus infections and seroprevalence of genotype gii.4-specific antibodies in a spanish population

2015

Genotype II.4 noroviruses (NoVs) are a leading cause of epidemic acute gastroenteritis in children and adults worldwide. The prevalence of different NoV genotypes causing outbreaks and sporadic cases of acute gastroenteritis in the region of Valencia, Spain, during a 4-year period (2008–11) was investigated. NoVs were detected in 42 out of 55 (76.3%) outbreaks and in 26 out of 332 (7.8%) sporadic cases of acute gastroenteritis. Genogroup GII strains were predominant in outbreaks and sporadic cases. Different genotype GII.4 variants were found (Yerseke_2006a, Den Haag_2006b, Apeldoorn_2007, and New Orleans_2009), with the latter variant detected most frequently (35.3%). A recombinant P domai…

Screening for inhibitors of HIV gp120-CD4 binding using an enzyme-linked immunoabsorbent assay.

1993

Binding of the HIV-1 major viral surface glycoprotein, gp120, to the major cell receptor, CD4, is essential for HIV infection of the target cell and syncytium formation. An enzyme-linked immunoassay using solid phase CD4 was used to quantitate the binding of HIV-1 gp120 to CD4, and to assess the activity and mechanism of action of putative inhibitors of that reaction. Monoclonal antibodies to the gp120 binding site on CD4 (e.g., Leu3a) blocked gp120 binding, while monoclonal antibodies to other portions of CD4 (e.g. OKT4) did not. Both aurintricarboxylic acid and sulfonated polysaccharides (e.g., dextran sulfate) blocked CD4-gp120 interactions by binding to the CD4 component. Human polyclon…

Conformational and linear epitopes on virus-like particles of human papillomavirus type 33 identified by monoclonal antibodies to the minor capsid pr…

1995

The organization of epitopes on the minor capsid protein L2 of human papillomavirus (HPV) type 33 has been analysed using three monoclonal antibodies (MAbs) generated against a large fragment of the L2 protein (amino acids 82-259) expressed as a glutathione S-transferase fusion protein. The topology of the L2 epitopes has been investigated with respect to the structure of HPV-33 virus-like particles (VLPs). Two of the MAbs reacted with linear epitopes which were mapped to amino acids 153-160 and 163-170, respectively. These epitopes were accessible in denatured but not in native VLPs consisting of L1 and L2, suggesting an internal location. The third antibody was unable to detect denatured …

COVID-19 Vaccination Willingness and Hesitancy in Patients With Inflammatory Bowel Diseases: Analysis of Determinants in a National Survey of the Ita…

2021

The coronavirus disease 2019 (COVID-19) pandemic has not finished yet, and the most promising option towards its ending is widespread vaccination. Because patients with inflammatory bowel diseases (IBDs), namely Crohn’s disease (CD) and ulcerative colitis (UC), often require immune-modifying treatment, which might increase the risk of opportunistic infection,1 their vaccination history for several infectious diseases is routinely checked, and when inadequate, vaccination is performed at diagnosis or ideally before immune suppressive treatment is started.1 However, IBD patients were not found to be at an increased risk of developing COVID-19 or of experiencing a more severe disease course.2
