The movements of the basis of maxilla 2 in Palaemon adspersus were examined using macro-video recordings, and the morphology of its setae was examined using both scanning and transmission electron microscopy. The basis of maxilla 2 performs stereotypical movements in the latero-medial plane and gently touches the food with a frequency of 3-5 Hz. The medial rim of the basis of maxilla 2 carries thr
Rearrangements of chromosome bands 12q13-15 are frequent in various benign mesenchymal and epithelial tumors, and the gene HMGA2 seems to be the most common target within this chromosome region. In the majority of cases, the rearrangements result in a fusion of the first three exons of HMGA2 with different translocation partners. Despite the large number of HMGA2 mutations that have been reported,
Popular Abstract in Swedish Avhandlingen har fokus på lungornas mekaniska egenskaper hos friska och vid akut lungskada och på metodutveckling för studier av lungmekanik. Kunskap om lungmekanik är av intresse inom intensivvården för att skräddarsy respirator-behandling och i lunglaboratoriet för diagnostik och utvärdering av patienter med olika typer av lungsjukdom. Vid respiratorbehandling kan föKnowledge about lung mechanics is of interest in intensive care to adjust mechanical ventilation and in the lung laboratory for diagnostics and evaluation of patients with various kinds of respiratory diseases. In mechanical ventilation a single inspiratory elastic pressure-volume (Pel/V) curve is difficult to interpret due to continuing re-expansion of collapsed lung units over a large pressure
In the framework of the ESO Large Programme ``First Stars'', veryhigh-quality spectra of some 70 very metal-poor dwarfs and giants wereobtained with the ESO VLT and UVES spectrograph. These stars are likelyto have descended from the first generation(s) of stars formed after theBig Bang, and their detailed composition provides constraints on issuessuch as the nature of the first supernovae, the eff
Swimming trajectories of length-matched deep-bodied and shallow-bodied crucian carp were quantified in the laboratory using motion analysis software and compared in terms of swimming velocity, turning behaviour and associated coefficients of variation. The mean velocities of the two morphs were similar, but slower than predicted, and there was no difference in turning behaviour. In line with predi
The RGD sequence is present in many extracellular matrix proteins and intracellular proteins, including caspases. Synthetic RGD peptides may affect adhesion, migration and tumour metastasis, or directly induce apoptosis. Several RGD peptides were synthesised, and their anti-adhesive and cytotoxic properties were analysed in vitro. The most active peptide (poly RGD) was also tested in vivo to asses
The nuclear-encoded chloroplast-localized Hsp21 is an oligomeric heat shock protein (Hsp), belonging to the protein family of small Hsps and @a-crystallins. We have investigated the effects of high temperature and oxidation treatments on the structural properties of Hsp21, both in purified recombinant form and in transgenicArabidopsis thalianaplants engineered to constitutively overexpress Hsp21.
The effects of hormone and growth factor signaling on gene expression contribute significantly to breast tumorigenesis and disease progression; however, the targets of signaling networks associated with deregulated growth are not well understood. We defined the dynamic transcriptional effects elicited in MCF7, T-47D, and MDA-MB-436 breast cancer cell lines by nine regulators of growth and differen
Implants of commercially pure titanium and polytetrafluoroethylene (PTFE) were inserted in the rat abdominal wall for 1, 6 or 12 wk. The foreign body reaction was evaluated by immunohistochemical quantification of monocytes/macrophages and by the thickness of the foreign-body capsule. At all time intervals, the majority of interfacial cells were ED1-positive while ED2-positive cells were localized
Aims Between 1998 and 2005, a number of definitions of the metabolic syndrome (MetS) have been proposed. The aim of this population-based cohort study was to compare prevalence rates and the prediction of cardiovascular disease (CVD) using different definitions of MetS. Methods A total of 5047 non-diabetic subjects (66% women), from the city of Malmo, Sweden, were followed. The incidence of fatal
The latest outburst of AG Peg has lasted for 150 years, which makes itthe slowest nova eruption ever recorded. During the time of IUEobservations (1978-1995) line profiles and intensity ratios of the N Vand C IV doublet components changed remarkably, and we discuss plausiblereasons. One of them is radiative pumping of Fe II which is investigatedby studying the fluorescence lines from pumped levels
Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning Kvartärtidens avlagringar döljer mycket och detaljerad information om palaeoklimatet och de lämpar sig därför väl för att modellera palaeoklimatets förändringar. Inlandsisar är av avgörande betydelse för klimatet under kvartärtiden. Deras tillväxt och avsmältning beror till stor del på klimatiska faktorer, såsom temperatur, nedeThis thesis presents results from studies on geomorphology, lithostratigraphy and ice flow patterns during the final termination and deglaciation of the last Scandinavian Ice Sheet in NE Germany. Ice flow patterns derived from till fabrics and glaciotectonical data indicate that short-lived marginal domes had formed during the advance and the retreat of the last Scandinavian Ice Sheet in NE German
The aim of this thesis is to study four important determinants for the prognosis of prosthodontic treatment, namely the patients expectations, personality traits, and satisfaction with treatment. The fourth aim is to relate the technical quality of the treatment to the patient's opinion about it. A specially designed questionnaire to explore expectations of treatment was sent to 489 patients await
OBJECTIVE: We sought to study changes in morphology and stent-graft configuration of descending thoracic aortic aneurysms after endovascular repair. METHODS: Twenty-three patients treated with custom-made stent-grafts were studied. The stent-graft consisted of continuous, stainless-steel Z stents mounted within a polyester graft. In the last 11 cases the stents were interconnected with 3 longitudi
The aim of this study was to estimate an influence of alpha-ketoglutarate (AKG) on volumetric bone density and geometrical and mechanical properties of the humerus in farm turkeys. All birds were kept under standard rearing conditions with constant access to water and appropriate feed, supplied in accordance with the stage of production cycle. Bone samples were collected 14 weeks after beginning o
