Reproductive outcome in a cohort of male and female rubber workers: a registry study.

PURPOSE: To investigate whether blue-collar employment in the Swedish rubber industry from 1973 onwards had a negative impact on reproductive health. METHODS: Pairs of mother and child, and triads of father-mother-child were obtained through linkage of a cohort of 18,518 rubber factory employees with the Swedish Population Registry. Birth outcomes were obtained from the Medical Birth Register for

En Fysikbro för kontakter mellan forskare och skola

Skolans undervisning i naturvetenskap kan lägga grunden för intresse och vidare studier inom de naturvetenskapliga och tekniksa ämnena, och strävar också efter att get en god allmänbildning som medborgarkunskap. I oktober 2011 anordnade NRCF ett nationell Fysikbromöte i Göteborg för att bygga broar mellan fysiker och gymnasielärare kring olika frågor.

A vertebral fracture in childhood is not a risk factor for disc degeneration but for Schmorl's nodes: a mean 40-year observational study.

STUDY DESIGN: Observational cohort study. OBJECTIVE: To evaluate by MRI whether a vertebral fracture during childhood is a risk factor for degeneration of adjacent discs. SUMMARY OF BACKGROUND DATA: Several studies infer that trauma is a major cause of disc degeneration. Only 1 study has by magnetic resonance imaging (MRI) evaluated disc degeneration in children with a former thoracic or lumbar ve

Determination of Radiative Lifetimes In Neutral Arsenic Using Time-resolved Laser Spectroscopy In the Vuv Region

Inspired by the recent Hubble Space Telescope first observations of arsenic in an astrophysical object we have determined the natural radiative lifetime of the upper states of two of the three resonance lines of As I. Short pulse laser excitation at 193.7 and 197.2 nm was achieved using different non-linear optical mixing schemes. Using time-resolved spectroscopy we obtain tau(4p(2)5s P-4(3/2))=4.

Maternal drug use during pregnancy and asthma risk among children.

Maternal use of some drugs, notably paracetamol and drugs for gastroesophageal reflux, has been associated with an increased risk of childhood asthma in the child. We wanted to analyze these associations with consideration to the confounding of maternal asthma.

Serum levels of a subset of cytokines show high interindividual variability and are not altered in rats transgenic for Huntington´s disease.

To evaluate whether cytokines are altered in peripheral blood of rats transgenic for the human Huntington´s disease mutation we investigated serum levels of GRO/KC, IL-1β, IL-13 and TNF-α at a symptomatic stage at 12 months of age. Overall serum levels of these cytokines were not significantly changed between transgenic HD rats and controls. Moreover, we observed a high interindividual variability
