Microarthropods mediate sperm transfer in mosses

Among flowering plants, animals commonly act as pollinators. We showed that fertile moss shoots attract springtails and mites, which in turn carry moss sperm, thereby enhancing the fertilization process. Previously, fertilization of mosses was thought to depend on the capacity of individual sperm to swim through a continuous water layer. The role of microarthropods in moss fertilization resembles

A randomised RSA study of Peri-apatite((TM)) HA coating of a knee prosthesis

Fifty knees scheduled for a total knee prosthesis were randomized in two groups. Both groups had a noncemented fixation of the porous-coated implants but one group received a prosthesis with ceramic coating on the porous surface of the implant. The knees were evaluated with RSA technique regarding micromotion the first two years. There were less micromotion in the coated group. The results indicat

Some indolic compounds as markers of the melanocyte activity

The melanocyte activity was studied by analysis of the urinary excretion of indolic and cysteinyldopa compounds. One eumelanin marker, 5,6-dihydroxy-indole-2-carboxylic acid was identified and quantified in normal urine. However, its low concentration and sensitivity to oxidation made it less suitable for clinical studies. A methylated derivative of this substance, 6-hydroxy-5-methoxyindole-2-carb

Plasma fibronectin supports neuronal survival and reduces brain injury following transient focal cerebral ischemia but is not essential for skin-wound healing and hemostasis

Fibronectin performs essential roles in embryonic development and is prominently expressed during tissue repair. Two forms of fibronectin have been Identified: plasma fibronectin (pFn), which Is expressed by hepatocytes and secreted In soluble form into plasma; and cellular fibronectin (cFn), an insoluble form expressed locally by fibroblasts and other cell types and deposited and assembled into t

Repeatability of sonographic measurements in clubfeet

Purpose: To assess the intra- and interobserver agreement of ultrasound assessment of clubfoot patho-anatomy in early childhood. Material and Methods: Seventeen clubfeet in 12 children were sequentially scanned by 2 examiners and repeat assessments were carried out independently. Three well-defined imaging planes were chosen to evaluate navicular displacement: the medial malleolus-navicular (MM-N)

Health care utilisation in a developing country -the case of Zambia

Popular Abstract in Swedish Syftet med denna avhandling är att bidra till vår förståelse för vårdutnyttjande och dess förklaringsfaktorer i utvecklingsländer, speciellt i sub-sahariska Afrika. Detta görs genom att fokusera på sjukvårdsutgifter och dess förklaringsfaktorer, samt valet att söka vård för att bota åkomman. Datamaterialete som används kommer från en hushållsundersökning från 1998 omfatThe aim of this thesis is to contribute to our understanding of health care utilisation and its determinants in developing countries, especially in sub-Saharan Africa. This is done by explicitly focusing on health care expenditures and its determinants as well as the choice to seek health care to cure the illness. Firstly, the focus is on a household’s expenditures for health care. The aim of this

Early TCR alpha beta expression promotes maturation of T cells expressing Fc epsilon RI gamma containing TCR/CD3 complexes

In a previous study we presented data indicating that the expanded population of CD4(-)CD8(-) (DN) alphabeta T cells in TCRalpha-chain-transgenic mice was partially if not entirely derived from gammadelta T cell lineage cells. The development of both gammadelta T cells and DN alphabeta T cells is poorly understood; therefore, we thought it would be important to identify the immediate precursors of

EEG depression and germinal layer haemorrhage in the newborn

Amplitude integrated EEG (aEEG) recordings from 32 mechanically ventilated infants, gestational age 32 weeks or less, were analysed. All recordings were started within 24 h of birth and continued for at least 50 h. Germinal layer haemorrhage (GLH) was diagnosed by repeated ultrasonography. In six infants neither GLH nor hypocalcaemia were diagnosed; aEEG in these infants rapidly became more active

Disseminated infection with Encephalitozoon intestinalis in AIDS patients: Report of 2 cases

Microsporidiosis must be regarded as a late opportunistic infection when HIV is advanced. In this article we describe 2 cases of disseminated infection with Encephalitozoon intestinalis. The first case had a local intestinal infection for > 1 y before it disseminated and microsporidia were found intracellularly in sputum. In the second case, spores were initially found in conjunctival cells, sinus

Management from four different perspectives

AIM: This study intended to illuminate nursing management in a developing organization from the perspectives of nurse managers, chief physicians, hospital directors and politicians. BACKGROUND: Increased responsibility in a changing health care system makes it important that nurses occupy advantageous positions so that they may safeguard and facilitate the development of their core area. METHODS:

Global Changes and European Terrestrial Ecosystems

Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. Despite the fact that the natural component of these changes has always occurred, today it's the anthropogenic component and its

Practices for preparing children for clinical examinations and procedures in Swedish pediatric wards.

This study sought to elucidate Swedish pediatric wards concerning the practice of informing children and their parents about clinical examinations and procedures. A semi-structured questionnaire was distributed to all 36 pediatric departments in Sweden, comprising of 83 wards. Fifty-eight (70%) of the wards responded. The results showed that 55 (95%) of the wards provided regular planned informati

Farmers as innovators

This working paper analyses the mindset and driving forces of innovators in the agricultural sector. The key drivers and incentives are different in this group than for the innovators from academic institution. Therefor the interaction with risk capital providers becomes problematic.

Behandling av artros. Etiologi och patofysiologi vid artros - terapeutiska konsekvenser

Artros (i engelskt språkbruk ”osteoarthritis”, ibland ”osteoarthrosis”) är en sjukdom med sakta förlopp och ibland gradvis försämring. Sjukdomen kan leda till total förstöring av leden och behov av operation med ersättning av leden med konstgjort material. För de flesta patienter med artros blir kirurgisk behandling dock aldrig nödvändig, besvären kan behandlas bra på annat sätt.Artros är inte en

Measured and predicted behaviour of steel beams and columns in fire

Analytical predictions of mechanical behaviour of fire-exposed steel structures are compared to experimental results obtained from three different research laboratories. Comparisons are made to axially free and restrained steel columns fire tested in Metz in France 1973-74, to simply supported steel beams fire tested in Germany and published in Stahlbau 1/1983 and to axially free and restrained st
