The legume goat's rue (Galega orientalis) and its microsymbiont Rhizobium galegae have an unusually strict host-bacteria specificity. The reason for this is not known. We have identified and analysed six genes in G. orientalis assumed to be involved in the recognition processes between legumes and rhizobia. The genes were isolated from a library made from nodulating roots. The genes were identifie
Popular Abstract in Swedish Alla har vi väl någon gång varit med om att datorer, dataprogram och datasystem inte fungerar som vi har tänkt oss. Inte sällan inträffar det fel och konstigheter som kan vara frustrerande och, i värsta fall, direkt farliga. Många gånger undrar man hur ett visst program eller system skall användas och hur de som har designat och byggt det har tänkt och resonerat. I sto
Background: Smoking and the use of smokeless tobacco have a detrimental impact on general and oral health. The relationship to dental caries is however still unclear. As caries is a multi-factorial disease with clear life-style, socio-economic and socio-demographic gradients, the tobacco use may be a co-variable in this complex rather than a direct etiological factor. Our aim was to analyze the im
Electrogoniometers are prone to crosstalk errors related to endblocks rotation (general crosstalk) and to the characteristics of each sensor (individual crosstalk). The aim of this study was to assess the crosstalk errors due to endblock misalignments and to propose a procedure to compensate for these errors in knee applications. A precision jig was used to simulate pure +/- 100 degrees flexion/ex
BackgroundPrediction of a woman's risk of a spontaneous preterm delivery (PTD) is a core challenge and an unresolved problem in today's obstetric practice. The objective of this study was to develop prediction models for spontaneous PTD (<37 weeks). MethodsA population-based register study of women born in Sweden with spontaneous onset of delivery was designed using Swedish Medical Birth Register
The properties of micro-porous ceramics are studied in the present work using a tunable diode-laser-based setup. The relative optical porosity is retrieved by using gas in scattering media absorption spectroscopy (GASMAS) - which yields the path length travelled by photons through the gas-filled pores - and frequency domain photon migration (FDPM) - which evaluates the mean optical path length (MO
European CH4 emissions are estimated for the period 2001-2006 using a four-dimensional variational (4DVAR) inverse modeling system, based on the atmospheric zoom model TM5. Continuous observations are used from various European monitoring stations, complemented by European and global flask samples from the NOAA/ESRL network. The available observations mainly provide information on the emissions fr
Mortality and morbidity have remained high in bacterial meningitis. Impairment of cerebral energy metabolism probably contributes to unfavorable outcome. Intracerebral microdialysis is routinely used to monitor cerebral energy metabolism, and recent experimental studies indicate that this technique may separate ischemia and non-ischemic mitochondrial dysfunction. The present study is a retrospecti
Chromosomal rearrangements resulting in the fusion of coding parts from two genes or in the exchange of regulatory sequences are present in approximately 20% of all human neoplasms. More than 1000 such gene fusions have now been described, with close to 100 of them in soft tissue tumours. Although little is still known about the functional outcome of many of these gene fusions, it is well establis
Neurofibroma is a benign tumor originating from Schwann cells in peripheral nerve sheaths and may occur as a sporadic tumor or as part of the dominantly inherited tumor syndrome NF1. NF1 is caused by constitutional mutations in the NF1 gene, located in chromosome band 17q11 Whereas the involvement of the NF1 gene in neurofibroma development in NF1 patients has been fairly well characterized, the s
* The ectomycorrhizal fungus Laccaria bicolor has the largest genome of all fungi yet sequenced. The large genome size is partly a result of an expansion of gene family sizes. Among the largest gene families are protein kinases and RAS small guanosine triphosphatases (GTPases), which are key components of signal transduction pathways. * Comparative genomics and phylogenetic analyses were used to e
For decades, unicellular yeasts have been general models to help understand the eukaryotic cell and also our own biology. Recently, over a dozen yeast genomes have been sequenced, providing the basis to resolve several complex biological questions. Analysis of the novel sequence data has shown that the minimum number of genes from each species that need to be compared to produce a reliable phyloge
The methodology for ready-made matrix-assisted laser desorption/ionization (MALDI) target plates covered with an optimized thin layer consisting of matrix and nitrocellulose has been developed. Piezoelectric microdispensing enabled sample depositions in a high-density array format of 2000 sample depositions on a conventionally sized target plate (45 x 47 mm). The sample depositions were made repro
The aim of this qualitative study was to identify and analyse the experiences of Swedish local health authority occupational therapists with regard to their participation in, and the implementation of, research. Data were collected from three focus-group interviews, with five different occupational therapists in each. The interviews were taped and transcribed and thereafter analysed using broad co
Today, most studies of genetic variation utilise molecular markers, making it possible to detect variation at the DNA level. This has greatly facilitated studies of genetic variation in population and evolutionary genetics, systematics and transmission genetics. By studying the inheritance of molecular markers in crosses, it is possible to map the markers, i.e. to determine their genomic positions
Economies in Transition (EiTs) exemplified by countries such as Poland, Ukraine, Belarus, Moldova etc. face many socio-economic and environmental challenges – energy security, high unemployment, poor transportation and municipal service infrastructure, and rural depopulation are common themes. Agricultural biofuel production offers a number of socio-economic co-benefits that can contribute to the
