- The outcome of obstetric brachial plexus palsy depends on the severity of the lesion of the nerve fibers. The aim of the prospective study is to evaluate if differences in force used in downward traction on the fetal head correlate to the number of nerve roots affected. At final neurological examination at 18 months of age, complete neurological recovery occurred in 80 of 98 children (82%). Downward traction of the fetal head was applied more often and with greater force in the group with persistent damage. There was a significant correlation between the force used to the number of nerve roots affected. The risk of persistent obstetric brachial plexus palsy at age 18 months depended on obstetric management and increased significantly with increasing force used in downward traction of the fetal head.

- Nematode-trapping fungi enter the parasitic stage by developing specific morphological structures called traps. The global patterns of gene expression in traps and mycelium of the fungus Monacrosporium haptotylum were compared. The trap of this fungus is a unicellular spherical structure called the knob, which develops on the apex of a hyphal branch. RNA was isolated from knobs and mycelium and hybridized to a cDNA array containing probes of 2822 EST clones of M. haptotylum. Despite the fact that the knobs and mycelium were grown in the same medium, there were substantial differences in the patterns of genes expressed in the two cell types. In total, 23(.)3% (657 of 2822) of the putative genes were differentially expressed in knobs versus mycelium. Several of these genes displayed sequence similarities to genes known to be involved in regulating morphogenesis and cell polarity in fungi. Among them were several putative homologues for small GTPases, such as rho1, rac1 and ras1, and a rho GDP dissociation inhibitor (rdi1). Several homologues to genes involved in stress response, protein synthesis and protein degradation, transcription, and carbon metabolism were also differentially expressed. In the last category, a glycogen phosphorylase (gph1) gene homologue, one of the most upregulated genes in the knobs as compared to mycelium, was characterized. A number of the genes that were clifferentially expressed in trap cells are also known to be regulated during the development of infection structures in plant-pathogenic fungi. Among them, a gas1 (mas3) gene homologue (designated gks1), which is specifically expressed in appressoria of the rice blast fungus, was characterized.

- Patients on the waiting list for total hip replacement: a 1-year follow-up study Untreated osteoarthritis (OA) in the hip causes pain and reduced physical and social functioning. The aim of this study was to evaluate the effect of waiting time on health-related quality of life (HRQOL), functional condition and dependence on help at the time of surgery and during follow-up 1 year after surgery. A further aim was to elucidate possible differences between men and women. Two hundred and twenty-nine consecutively included patients with OA in the hip were interviewed when assigned to the waiting list, again 1 week prior to surgery with unilateral total hip replacement (THR), and 1 year after surgery. Health-related quality of life and function were measured using the Nottingham Health Profile, EuroQoL and the Western Ontario and McMaster Universities Osteoarthritis Index. The result showed that the average waiting time was 239 days, that 15% of the patients were operated on within 3 months, and that 21% had to wait more than 6 months. At the time of surgery, HRQOL had deteriorated significantly (p < 0.05) and the number of patients receiving support from relatives had increased from 31% to 58% during the wait. At the 1-year follow-up, both HRQOL and functional condition had improved significantly despite the wait, and the need for support from relatives had decreased to 11% (p < 0.001). In conclusion, long waiting time for THR is detrimental to patients HRQOL causing reduced functional condition, pain and increased need for support from relatives, which limit the independence in daily life.

Diskutera fysik i grupp! : Utgå från kontextrika problem
- 2007
-
Rapport (populärvet., debatt m.m.)abstract
- I denna bok berättar vi om våra erfarenheter från undervisning i form av gruppdiskussioner runt kontextrika (verklighetsanknutna) problem, vi ger tips på hur sådana problem kan konstrueras och vi delar med oss av exempel på kontextrika problem. Vi som skrivit denna bok har använt gruppdiskussioner runt kontextrika problem under några år i vår egen undervisning och vi tycker oss se att denna undervisning ofta fungerar bra. Vi har också deltagit i ett gemensamt forskningsprojekt med syftet att förstå hur användningen av gruppdiskussioner med kontextrika problem påverkar studenternas/elevernas förståelse av fysikaliska begrepp. Vi undersökte även hur problemen bör utformas för att intressera gymnasieeleverna. Resultaten från detta projekt utgör en bakgrund för boken.

O-O bond cleavage in dinuclear peroxo complexes of iron porphyrins : a quantum chemical study

- To gain insight into the mechanisms of O-2 activation and cleavage in metalloenzymes, biomimetic metal complexes have been constructed and experimentally characterized. One such model complex is the dinuclear peroxo complex of iron porphyrins observed at low temperature in a noncoordinating solvent. The present theoretical study examines the O-O bond cleavage in these complexes, experimentally observed to occur either at increased temperature or when a strongly coordinating base is added. Using hybrid density functional theory, it is shown that the O-O bond cleavage always occurs in a state where two low-spin irons (S = +/- 1/2) are antiferromagnetically coupled to a diamagnetic state. This state is the ground state when the strong base is present and forms an axial ligand to the free iron positions. In contrast, without the axial ligands, the ground state of the clinuclear peroxo complex has two high-spin irons (S = +/- 5/2) coupled antiferromagnetically. Thus, the activation barrier for O-O bond cleavage is higher without the base because it includes also the promotion energy from the ground state to the reacting state. It is further found that this excitation energy, going from 10 unpaired electrons in the high-spin case to 2 in the low-spin case, is unusually difficult to determine accurately from density functional theory because it is extremely sensitive to the amount of exact exchange included in the functional.
