BACKGROUND No national study has investigated whether immigrant workers are less likely than U.S.-workers to seek medical treatment after occupational injuries and whether the payment source differs between two groups. METHODS Using the 2004-2009 Medical Expenditure Panel Survey (MEPS) data, we estimated the annual incidence rate of nonfatal occupational injuries per 100 workers. Logistic reg...

The present study was designed to investigate the effect of industrial pollution on the physical and mental health of the tannery workers as well as the related residential area’s people of Hagaribag in Dhaka city. One hundred and sixty (80 tannery workers and 80 residential area’s people) respondents were selected by purposive sampling method as samples for the present study. Three hypotheses ...

18 Inclusive-fitness theory highlights monogamy as a key driver of altruistic sib-rearing. Accordingly, 19 monogamy should promote the evolution of worker sterility in social insects when sterile workers 20 make for better helpers. However, a recent population-genetics analysis (Olejarz et al. 2015) found 21 no clear effect of monogamy on worker sterility. Here, we revisit this analysis. First,...

In today's world the agricultural sector employs half of the world's labour force with an estimated 1.3 billion workers active in agricultural production worldwide. The majority of agricultural workers are found in developing countries. A great majority are small scale farmers. They have been more often victims rather than beneficiaries of the green revolution, the technological development and...

BACKGROUND Agricultural workers are exposed to organic dust containing endotoxins, mites, and moulds. AIMS To compare the occurrence of ischaemic heart disease (IHD) among male and female livestock and agricultural workers with gainfully employed men and women in Sweden. METHODS Male and female livestock and agricultural workers were identified in the Swedish National Censuses of 1970 and 1...

To assess the prevalence and the characteristics of exercise-induced bronchoconstriction (EIB) in subjects occupationally exposed to organic dusts we performed a cross-sectional study including 152 exposed subjects (67 textile workers, 42 agricultural workers, and 43 bakers) and 72 unexposed controls. Evaluation of exposed and unexposed subjects included a questionnaire, skin prick tests to com...

This study reports on a survey conducted to explore the awareness and extent of utilization of The Essential Electronic Agricultural Library (TEEAL) database resources by academic staff at the faculty of Agriculture, University of Calabar, Nigeria. Structured Questionnaire was designed and used for data collection. Eighty copies of the questionnaire were randomly distributed to respondents in t...

A small cationic peptide (JH8944) was tested for activity against a number of pathogens of agricultural crops. JH8944 inhibited conidium growth in most of the tested plant pathogens with a dose of 50 μg/ml, although one isolate of Fusarium oxysporum was inhibited at 5 μg/ml of JH8944. Most conidia of Fusarium graminearum were killed within 6 hours of treatment with 50 μg/ml of JH8944. Germinati...

BACKGROUND In acute-care hospitals, no evidence of a protective effect of healthcare worker (HCW) vaccination on hospital-acquired influenza (HAI) in patients has been documented. Our study objective was to ascertain the effectiveness of influenza vaccination of HCW on HAI among patients. METHODS A nested case-control investigation was implemented in a prospective surveillance study of influe...

The importance of the nitrate (NO3-) transporter for yield and nitrogen-use efficiency (NUE) in rice was previously demonstrated using map-based cloning. In this study, we enhanced the expression of the OsNRT2.1 gene, which encodes a high-affinity NO3- transporter, using a ubiquitin (Ubi) promoter and the NO3--inducible promoter of the OsNAR2.1 gene to drive OsNRT2.1 expression in transgenic ri...
