A seroepidemiological study on human parvovirus (B19) in Japan was undertaken with serum samples randomly collected from healthy Japanese populations (416 in 1973, 675 in 1984 and 508 in 1987/88). All samples were tested for anti-B19 IgG antibody by the indirect antigen-capture ELISA. The antibody prevalence for ages 0-9 years old in 1984 was significantly higher (16%) than that in 1973 (2%), w...
We analyzed a panel of cationic molecules secreted in the culture medium of human respiratory epithelial cells (REC) upon activation by IL-1β and different pathogen-associated molecular patterns. A 9 kDa fragment derived from β2-microglobulin (B2M) was identified and named shed 9 kDa B2M (sB2M-9). The primary structure of sB2M-9 was revealed to increase its pI value that potentially could play ...
BACKGROUND The majority of Swiss amphibians are threatened. There is a range of factors which have been discussed as possible causes for their decline, including plant protection products (PPPs). RESULTS The influence of PPPs on amphibian populations has not yet been studied to any great extent, neither for active ingredients nor for the wetting agents, breakdown products or tank mixtures. A ...
Mycotoxins are abiotic hazards produced by certain fungi that can grow on a variety of crops. Consequently, their prevalence in plant raw materials may be relatively high. The concentration of mycotoxins in finished products is usually lower than in raw materials. In this review, occurrence and toxicology of the main mycotoxins are summarised. Furthermore, methodological approaches for exposure...
OBJECTIVE To evaluate ascertainment of the onset of community transmission of influenza A/H1N1 2009 (swine flu) in England during the earliest phase of the epidemic through comparing data from two surveillance systems. DESIGN Cross sectional opportunistic survey. STUDY SAMPLES Results from self samples by consenting patients who had called the NHS Direct telephone health line with cold or f...
A retrospective, space-time study of whooping cough cases reported to the Public Health Agency of Barcelona, Spain between the years 2000 and 2011 is presented. It is based on 633 individual whooping cough cases and the 2006 population census from the Spanish National Statistics Institute, stratified by age and sex at the census tract level. Cluster identification was attempted using space-time...
Incident to a study of hemoglobin regeneration in the chronic, hemorrhagic anemia of dogs in this laboratory, the analysis for iron in biological materials became necessary. The difficulty experienced in such iron estimations has been reported by many authors. The variable and contradictory observations in the older literature and the multiplicity of complicated methods advocated for iron analy...
BACKGROUND We set out to identify the level of previous exposure to influenza A (H1N1) in unvaccinated healthcare workers (HCWs) at the peak of the pandemic outbreak in the UK, with control samples collected prior to the outbreak. METHODS Cross-sectional study (seroprevalence assessed before and at pandemic peak, with questionnaire data collected at peak of outbreak) in HCWs in Scotland. RE...
