OBJECTIVES: The primary objective of this study was to examine how a group of Swedish teachers rate aspects of their working environment that can be presumed to have an impact on vocal behavior and voice problems. The secondary objective was to explore the prevalence of voice problems in Swedish teachers. METHOD: Questionnaires were distributed to the teachers of 23 randomized schools. Teaching st

PURPOSE OF REVIEW: The purpose of the review is to show the similarities between haemolytic disease of the foetus and newborn (HDFN) and foetal and neonatal alloimmune thrombocytopenia (FNAIT) and to describe the background and challenges related to the current endeavours of developing a prophylaxis against FNAIT. The rationale for this prophylaxis is similar to the prophylaxis which has been used

Background Ezrin is a cytoskeletal protein involved in tumour growth and invasion. Ezrin expression has been suggested to play a role in metastasis in paediatricosteosarcoma and rhabdomyosarcoma. Aim To evaluate the prognostic role of ezrin in a large series of soft tissue sarcoma of the extremities and trunk wall. Methods Ezrin expression was evaluated by immunohistochemistry on tissue microarray

The present review discusses two types of biological rhythms, namely, circadian rhythms and circannual rhythms. Humans possess a circadian rhythm of approximately 24 hours, which is regulated by neural and hormonal processes. The synchronisation of this rhythm with the solar day and night is maintained through entrainment mainly by light. Dark environments completely lacking windows may have a neg

I slutet av 1940-talet beslutade Sverige att ta emot ett begränsat antal icke-arbetsföra flyktingar. Denna artikel ger den internationella och nationella bakgrunden till detta beslut, beslut som gav upphov till framväxten av en specifik flyktingverksamhet inom socialtjänsten. Artikelns syfte är att med hjälp av ett historiskt perspektiv förstå bakgrunden till socialtjänstens arbete med flyktingar

BACKGROUND: Although 2-20% of breast cancer patients develop a contralateral breast cancer (CBC), prognosis after CBC is still debated. Using a unique patient cohort, we have investigated whether time interval to second breast cancer (BC2) and mode of detection are associated to prognosis. METHODS: Information on patient-, tumour-, treatment-characteristics, and outcome was abstracted from patien

Climbing fiber discharges within the rat cerebellar cortex have been shown to display synchrony, especially for climbing fibers terminating in the same parasagittal bands. In addition, Purkinje cells which have the smallest rostrocaudal separation also seem to have the highest degree of synchrony. But this has so far only been investigated for distances down to 250 mum. In the present study, we wa

This paper overviews traffic engineering problems encountered in the design of multiple networks. We mainly inspect the problem of introducing an n x 64kbit/s service into a non-hierarchial telephone network and focus on network dimensioning.

Granins are major constituents of dense-core secretory granules in neuroendocrine cells, but their function is still a matter of debate. Work in cell lines has suggested that the most abundant and ubiquitously expressed granins, chromogranin A and B (CgA and CgB), are involved in granulogenesis and protein sorting. Here we report the generation and characterization of mice lacking chromogranin B (
