- Dizziness is a common and often untreated symptom in the general population. The aim of this study was to investigate the effects of a combined cognitive-behavioral/vestibular rehabilitation (VR) program, using a randomized control design. A total of 29 participants were randomized to treatment consisting of psychoeducation, vestibular exercises, relaxation and cognitive interventions, or to serve as waiting list controls. Measures of dizziness-related handicap, dizziness-provoking movements, and daily diary registrations of dizziness symptoms at pre- and post-treatment showed statistically significant improvements in many domains, which translated to moderate effect sizes. These findings provide preliminary support for the combination of Cognitive-behavioral therapy (CBT) and VR methods in the treatment of dizziness.

- Palliative imatinib treatment has dramatically improved survival in patients with malignant gastrointestinal stromal tumours, particularly in patients with tumours harbouring activating KIT mutations. To evaluate the effectiveness of adjuvant imatinib after radical surgery, a consecutive series of patients with high-risk tumours (n=23) was compared with historic controls (n=48) who were treated with surgery alone. The mean follow-up period was over 3 years in both groups. Only 1 out of 23 patients (4%) in the adjuvant treatment group developed recurrent disease compared to 32 out of 48 patients (67%) in the control group. This preliminary study indicates that 1 year of adjuvant treatment with imatinib dramatically improves recurrence-free survival. Confirmation of these findings awaits the results of ongoing randomised studies.

- BACKGROUND & AIMS: Gain-of-function mutations in the KIT receptor tyrosine kinase gene and rare mutations in the platelet-derived growth factor receptor alpha (PDGFRA) gene are important events in gastrointestinal stromal tumor (GIST) development. Different mutations are reportedly associated with distinctive phenotypes and possibly clinical behavior. We investigated the correlation among mutation type, phenotype, and clinical course in a preimatinib, population-based series of GIST with long-term follow-up. METHODS: Genomic DNA from 177 GIST patients was analyzed for KIT exons 9, 11, 13, and 17 and PDGFRA exons 12 and 18 mutations using denaturating high-performance liquid chromatography and bidirectional sequencing. RESULTS: KIT exon 11 mutations were detected in 101 of 177 GIST (61 deletions, 23 missense mutations, and 17 duplications); wild-type (WT) KIT and PDGFRA were detected in 63; KIT exon 9 and exon 17 mutations in 6 and 1, respectively; and PDGFRA exons 12 and 18 mutations in 3 each.

Kostnadsfritt eller avgiftsbelagt boendestöd för personer med psykiska funktionshinder
- 2007
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Föreliggande rapport omfattar tre delstudier: - En kartläggning via enkätstudie av hur många kommuner i landet som tar ut en avgift för boendestöd - En intervjustudie med ett antal kommuner ang. deras ställningsstagande kring avgifter för boendestöd - En studie om kostnader och intäkter gällande avgifter för boendestöd Resultatet visade att en klar majoritet av de undersökta kommunerna inte tar ut någon avgift för boendestöd i vare sig ordinärt boende eller bostäder med särskild service. I studien om intäkter och kostnader för hanteringen av avgiftssystemet finns det en tendens för både större kostnader och därmed negativa vinster i kommuner med ett mindre antal individer som betalar en avgift för sitt boendestöd. Intervjuerna med kommuner om deras ställningstagande visade att det finns ett antal argument för att ta ut avgifter och ett antal argument för motsatsen. Dessa argument redovisas och rapporten med en rekommendation att inte avgiftsbelägga boendestöd för personer med psykiska funktionshinder Rapporten är nr 22 (av 24st) i Boendeprojektet som är ett riktat projekt inom ramen för kansliet för Nationell psykiatrisamordning. Projektmedel beviljades av Socialstyrelsen år 2005 för ett uppdrag inom satsningen på psykiatri och socialt stöd och omsorg för personer med psykisk sjukdom och/eller psykiska funktionshinder. Projektet har letts av David Brunt, Institutionen för vårdvetenskap och socialt arbete, Växjö universitet.

Precursor evaluation for in situ InP nanowire doping
- 2008

Tidskriftsartikel (refereegranskat)abstract
- The use of tetraethyltin (TESn) and dimethylzinc (DMZn) as in situ n- and p-dopant precursors during particle-assisted growth of InP nanowires is reported. Gate voltage dependent transport measurements demonstrate that the nanowires can be predictably synthesized as either n- or p-type. These doped nanowires can be characterized based on their electric field response and we find that n- type doping scales over a range from 10(17) to 10(19) cm(-3) with increasing input TESn dopant molar fraction. On the other hand, the p-type doping using DMZn saturates at low levels, probably related to a strong increase in nanowire growth rate with increasing DMZn molar fractions. By optimizing growth conditions with respect to tapering, axial pn-junctions exhibiting rectifying behavior were fabricated. The pn-junctions can be operated as light emitting diodes.

SNARE proteins mediate fusion between cytosolic lipid droplets and are implicated in insulin sensitivity.

Tidskriftsartikel (refereegranskat)abstract
- The accumulation of cytosolic lipid droplets in muscle and liver cells has been linked to the development of insulin resistance and type 2 diabetes. Such droplets are formed as small structures that increase in size through fusion, a process that is dependent on intact microtubules and the motor protein dynein. Approximately 15% of all droplets are involved in fusion processes at a given time. Here, we show that lipid droplets are associated with proteins involved in fusion processes in the cell: NSF (N-ethylmaleimide-sensitive-factor), alpha-SNAP (soluble NSF attachment protein) and the SNAREs (SNAP receptors), SNAP23 (synaptosomal-associated protein of 23 kDa), syntaxin-5 and VAMP4 (vesicle-associated membrane protein 4). Knockdown of the genes for SNAP23, syntaxin-5 or VAMP4, or microinjection of a dominant-negative mutant of alpha-SNAP, decreases the rate of fusion and the size of the lipid droplets. Thus, the SNARE system seems to have an important role in lipid droplet fusion. We also show that oleic acid treatment decreases the insulin sensitivity of heart muscle cells, and this sensitivity is completely restored by transfection with SNAP23. Thus, SNAP23 might be a link between insulin sensitivity and the inflow of fatty acids to the cell.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The aim of this retrospective population-based study, which was conducted before the introduction of imatinib, was to evaluate the role of surgery in patients with gastrointestinal stromal tumours (GISTs) and clarify which subgroups might benefit from adjuvant treatment. METHODS: Two hundred and fifty-nine patients with clinically detected GISTs were studied. Univariate and multivariate analyses were performed to identify predictors for recurrent disease and survival. RESULTS: Thirty of 48 patients with high-risk GISTs and all of those with overtly malignant tumours developed recurrent tumour after complete (R0) resection. Thirty-four of 38 first recurrences occurred within 36 months of surgery. No recurrence was observed after 72 months. R0 resection, achieved in 48 (80 per cent) of 60 patients with high-risk tumours, was significantly associated with a decreased risk of death from tumour recurrence (P = 0.008). CONCLUSION: Completeness of surgical resection is an independent prognostic factor in patients with high-risk GISTs. A period of adjuvant treatment with imatinib is recommended in patients with high-risk or overtly malignant GISTs who have undergone R0 resection and have a tumour-free interval of less than 6 years.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Because of the important role of membrane proteins in adhesion, invasion, and intracellular survival of pathogens in the host, membrane proteins are of potential interest in the search for drug targets or biomarkers. We have established a mass spectrometry-based method that allows characterization of the outer membrane protein (OMP) profile of clinical isolates from of the human gastric pathogen Helicobacter pylori. Subcellular fractionation and one-dimensional gel electrophoresis (1D-GE) analysis was combined with nano-liquid chromatography Fourier transform-ion cyclotron resonance mass spectrometry (nano-LC FT-ICR MS) and tandem mass spectrometry (MS/MS) analysis of fifteen H. pylori strains associated either with duodenal ulcers, gastric cancer, or isolated from asymptomatic H. pylori infected carriers. Over 60 unique membrane or membrane-associated proteins, including 30 of the 33 theoretically predicted OMPs, were identified from the strains. Several membrane proteins, including Omp11 and BabA, were found to be expressed by all strains. In the search for clinical markers we found that Omp26 was expressed by all disease-related strains but was only present in one out of five strains from asymptomatic carriers, which makes Omp26 a potential target for further investigation in the search for proteins unique to disease-related H. pylori strains. In addition, presence of Omp30 and absence of Omp6 seemed to be associated with H. pylori strains causing duodenal ulcer.

HpaA is essential for Helicobacter pylori colonization in mice
- 2006
-
Ingår i: Infect Immun. ; 74:2, s. 920-6
-
Tidskriftsartikel (refereegranskat)abstract
- Infection with the human gastric pathogen Helicobacter pylori can give rise to chronic gastritis, peptic ulcer, and gastric cancer. All H. pylori strains express the surface-localized protein HpaA, a promising candidate for a vaccine against H. pylori infection. To study the physiological importance of HpaA, a mutation of the hpaA gene was introduced into a mouse-adapted H. pylori strain. To justify that the interruption of the hpaA gene did not cause any polar effects of downstream genes or was associated with a second site mutation, the protein expression patterns of the mutant and wild-type strains were characterized by two different proteomic approaches. Two-dimensional differential in-gel electrophoresis analysis of whole-cell extracts and subcellular fractionation combined with nano-liquid chromatography-Fourier transform ion cyclotron resonance mass spectrometry for outer membrane protein profiling revealed only minor differences in the protein profile between the mutant and the wild-type strains. Therefore, the mutant strain was tested for its colonizing ability in a well-established mouse model. While inoculation with the wild-type strain resulted in heavily H. pylori-infected mice, the HpaA mutant strain was not able to establish colonization. Thus, by combining proteomic analysis and in vivo studies, we conclude that HpaA is essential for the colonization of H. pylori in mice.
