Human immunodeficiency virus-2 (HIV-2) is less pathogenic than HIV-1, and the disease progression in HIV-2-infected individuals seems to be similar to that seen in HIV-1-infected long-term nonprogressors. Cell-mediated immune responses and the production of noncytotoxic CD8(+) T-cell antiviral factors (CAF) and beta-chemokines have been correlated to protection against HIV-1 and associated with as

Ectomycorrhizal (EM) fungi growing in symbiosis with tree seedlings have been found in laboratory experiments to stimulate weathering and the uptake of nutrients from silicate minerals. In the present study, we used the natural abundance of strontium isotopes to confirm that these fungi obtain strontium from biotite and microcline under field conditions. Minerals enriched in radiogenic Sr-87 were

A need for a hand-ergonomics training kit has been identified to increase critical thinking concerning choice of hand tools. This study deals with the design, use and evaluation of a hand-ergonomics training kit for use in ergonomics training programmes. The effects on awareness of hand ergonomics among training course participants have been evaluated by means of a questionnaire and interviews at

The remarkable variation in plumage and morphological characters in the redpoll complex Carduelis flammea-hornemanni has puzzled taxonomists for several decades. In contrast, molecular studies have not revealed any genetic differentiation among the phenotypic redpoll forms. This could either be a result of high present-day gene flow or morphological differentiation following a rapid and recent pop

Recent studies of semen quality in men from the general population gave rise to the hypothesis of an East-West gradient in semen quality in the Nordic-Baltic area, with the highest sperm counts in Estonia, Lithuania and Finland, and the lowest in Denmark (30% difference in mean concentration). Genetic, lifestyle-related and environmental factors - alone or in combination - were suggested to be res

It is well known that the effects of direct (lethal) predator-prey interactions propagate through food webs (the trophic cascade). However, in the present study we show for the first time that, parallel to the trophic cascade, there exists a behavioral cascade in the sense that behavioral responses, induced by the nonlethal presence of a top predator, are transmitted down the food chain over more

Background. Gynecologic examination is a common measure in reproductive health care. Many women experience the examination as a more or less negative event, with shortcomings in the examiner's behavior. The aim of the study was to describe, in terms of critical incidences, women's experiences concerning the personnel's behavior in the situation of gynecologic examination. Methods. The informants w

Previous time-use research suggests that it is highly relevant for an occupational therapist to estimate time use and occupational engagement in order to understand some of the determinants of wellbeing for people with schizophrenia. This article describes the development and the testing of the psychometric properties of an instrument, Profiles of Occupational Engagement in people with Schizophren
