- Background: It is unknown whether renal pathology lesions in immunoglobulin A nephropathy (IgAN) correlate with renal outcomes over decades of follow-up.Methods: In 1130 patients of the original Validation Study of the Oxford Classification for IgA Nephropathy (VALIGA) cohort, we studied the relationship between the MEST score (mesangial hypercellularity, M; endocapillary hypercellularity, E; segmental glomerulosclerosis, S; tubular atrophy/interstitial fibrosis, T), crescents (C) and other histological lesions with both a combined renal endpoint [50% estimated glomerular filtration rate (eGFR) loss or kidney failure] and the rate of eGFR decline over a follow-up period extending to 35 years [median 7 years (interquartile range 4.1-10.8)].Results: In this extended analysis, M1, S1 and T1-T2 lesions as well as the whole MEST score were independently related with the combined endpoint (P < 0.01), and there was no effect modification by age for these associations, suggesting that they may be valid in children and in adults as well. Only T lesions were associated with the rate of eGFR loss in the whole cohort, whereas C showed this association only in patients not treated with immunosuppression. In separate prognostic analyses, the whole set of pathology lesions provided a gain in discrimination power over the clinical variables alone, which was similar at 5 years (+2.0%) and for the whole follow-up (+1.8%). A similar benefit was observed for risk reclassification analyses (+2.7% and +2.4%).Conclusion: Long-term follow-up analyses of the VALIGA cohort showed that the independent relationship between kidney biopsy findings and the risk of progression towards kidney failure in IgAN remains unchanged across all age groups and decades after the renal biopsy.

- Effects of the addition of a cationic amino acid-based synthetic amphiphile, arginine N-lauroyl amide dihydrochloride (ALA), to a lipid-based transfection formulation have been investigated. It is shown that the inclusion of ALA results in a substantial enhancement of the transfection capability of lipoplexes prepared with liposomes of 1-palmitoyl-2-oleoyl-sn-glycero-3-ethylphosphocholine and cholesterol, which themselves mediate highly efficient transfection. A possible explanation for the increased biological activity is that ALA adsorbed to the surface of the DNA-lipid complexes is involved in triggering internalization. However, in order to identify possible additional factors underlying the enhanced transfection efficiency, the physical properties of formulations with and without ALA were characterized using cryo-transmission electron microscopy, dynamic light scattering, and an ethidium bromide intercalation assay. ALA seems to have limited influence on the initial internal structure of the complexes and the protection of DNA, but its presence is found to decrease the average effective size of the dispersed particles; this change in size may be important in improving the biological activity. Furthermore, ALA can act to influence the transfection efficiency of the formulation by promoting the release of DNA following internalization in the transfected cells.

- Background and PurposeNO deficiency and oxidative stress are crucially involved in the development or progression of cardiovascular disease, including hypertension and stroke. We have previously demonstrated that acute treatment with the newly discovered organic nitrate, 2-nitrate-1,3-dibuthoxypropan (NDBP), is associated with NO-like effects in the vasculature. This study aimed to further characterize the mechanism(s) and to elucidate the therapeutic potential in a model of hypertension and oxidative stress. Experimental ApproachA combination of ex vivo, in vitro and in vivo approaches was used to assess the effects of NDBP on vascular reactivity, NO release, NADPH oxidase activity and in a model of hypertension. Key ResultsEx vivo vascular studies demonstrated NDBP-mediated vasorelaxation in mesenteric resistance arteries, which was devoid of tolerance. In vitro studies using liver and kidney homogenates revealed dose-dependent and sustained NO generation by NDBP, which was attenuated by the xanthine oxidase inhibitor febuxostat. In addition, NDBP reduced NADPH oxidase activity in the liver and prevented angiotensin II-induced activation of NADPH oxidase in the kidney. In vivo studies showed that NDBP halted the progression of hypertension in mice with chronic angiotensin II infusion. This was associated with attenuated cardiac hypertrophy, and reduced NADPH oxidase-derived oxidative stress and fibrosis in the kidney and heart. Conclusion and ImplicationsThe novel organic nitrate NDBP halts the progression of angiotensin II-mediated hypertension. Mechanistically, our findings suggest that NDBP treatment is associated with sustained NO release and attenuated activity of NADPH oxidase, which to some extent requires functional xanthine oxidase.

- Autophagy is one of the major intracellular catabolic pathways, but little is known about the composition of autophagosomes. To study the associated proteins, we isolated autophagosomes from human breast cancer cells using two different biochemical methods and three stimulus types: amino acid deprivation or rapamycin or concanamycin A treatment. The autophagosome- associated proteins were dependent on stimulus, but a core set of proteins was stimulus- independent. Remarkably, proteasomal proteins were abundant among the stimulus- independent common autophagosome- associated proteins, and the activation of autophagy significantly decreased the cellular proteasome level and activity supporting interplay between the two degradation pathways. A screen of yeast strains defective in the orthologs of the human genes encoding for a common set of autophagosome- associated proteins revealed several regulators of autophagy, including subunits of the retromer complex. The combined spatiotemporal proteomic and genetic data sets presented here provide a basis for further characterization of autophagosome biogenesis and cargo selection.

- OBJECTIVE: Patients with non-muscle-invasive bladder cancer are traditionally followed by repeat cystoscopy and urine cytology. A fluorescence in situ hybridisation technique called UroVysion((R)) (UV) is now available for clinical diagnosis of urothelial cancer cells. The aim of the present study was to compare UV analysis with routine follow-up methods. METHODS: We studied an unselected cohort of patients undergoing cystoscopy follow-ups at two Swedish centres in 2004-2005. All patients were investigated by cystoscopy, cytology, and UV assay. The UV assay was evaluated with regards to sensitivity, specificity, and positive predictive value for tumour recurrence. RESULTS: In all, 159 cases were analysed. UV had a 30% overall sensitivity for the 27 biopsy-proven recurrences and 70% sensitivity for high-risk tumours (pT1 and carcinoma in situ [CIS]). The specificity of UV was 95%. UV detected all six CIS cases in the study and was predictive in two additional patients who developed CIS within 1 yr of inclusion. Cytology was positive in four of those eight CIS cases and atypical in the other four. CONCLUSIONS: The UV assay cannot replace cystoscopy for surveillance of patients with non-muscle-invasive bladder cancer, but it may be valuable as a supplement to traditional measures for detecting CIS. Before any conclusions can be drawn regarding the efficacy of novel markers of bladder cancer, they must be studied in bladder cancer patients undergoing endoscopic surveillance.

Annan publikation (populärvet., debatt m.m.)abstract
- Haunted by Shadows of the Future: ARTEFACTS identifierar föremål från slutet av1960-talet till slutet av 1970-talet som har ett personligt eller familjärt samband medmänniskorna och samhället under denna tid, och som innefattar en särskild känslaav tillhörighet, en önskan att vara en del av det moderna svenska samhälle som togform vid den tiden. Resultatet av detta kollektiva sökande är en samling artefakter,företeelser och föremål i hemmet, sammanflätade med rika personliga berättelser ochupptäckter. Dessa inbegriper en försäkringsförsäljares portfölj, en rullbandspelaresom fångade ett populärt radioprogram med en pratshow, en inspelning med enlandsflyktig somalisk författare, tidiga exemplar av plastleksaker, diabilder frånsemestrar, vykortssamlingar och super 8 filmer, textiltryck med popmönster ochmönster för klädesplagg, lokala grönplanteringar, en affärskedjas lansering av ettanti-varumärke, den revolutionerande ”du”-reformen, och andra samtida referenser,som ett svenskt kvinnomanifest och en populär oljevärmare från Iran. Stadsmuseetsvisningslägenhet i Tensta på Kämpingebacken 13, tjänar här som en tidskapsel somöppnar en hel värld bakom dessa YTTERST vardagliga föremål.
