Adolescent boys with asthma – a pilot study on embodied gendered habits

2012

Thomas Westergren,1 Ulla-Britt Lilleaas21Faculty of Health and Sport Science, Department of Health and Nursing Science, University of Agder, Grimstad, Norway; 2Faculty of Humanities and Education, Centre for Gender and Equality, University of Agder, Kristiansand, NorwayPurpose: Asthma is a common chronic disease with gender differences in terms of severity and quality of life. This study aimed to understand the gendered practices of male asthmatic adolescents in terms of living with and managing their chronic disease. The study applied a sociological perspective to identify the gender-related practices of participants and their possible consequences for health and disease.Patients and metho…

Biowaste in a circular bioeconomy in Mediterranean area: A case study of compost and vermicompost as growing substrates alternative to peat

2020

European policies are advocating a transition toward circular bio-economy, an economy aiming at reducing the dependence from fossil-based resources, limiting greenhouse gas emissions and environmental impacts. The aim of this paper is to assess the potential for circularity for bio-waste and related by-products, to highlight the role of compost and vermicompost in the circular bioeconomy and their use in the agricultural sector. Three different substrates were tested in the soilless cultivation of Salvia officinalis, a Mediterranean nutraceutical and healthy plant: vermicompost (40%), compost (40%) and peat (100%). The average values of the main biometric parameters were calculated and comp…

Evidence for mechanical and chemical alteration of iron-nickel meteorites on Mars: Process insights for Meridiani Planum

2011

The weathering of meteorites found on Mars involves chemical and physical processes that can provide clues to climate conditions at the location of their discovery. Beginning on sol 1961, the Opportunity rover encountered three large iron meteorites within a few hundred meters of each other. In order of discovery, these rocks have been assigned the unofficial names Block Island, Shelter Island, and Mackinac Island. Each rock presents a unique but complimentary set of features that increase our understanding of weathering processes at Meridiani Planum. Significant morphologic characteristics interpretable as weathering features include (1) a large pit in Block Island, lined with delicate iro…

Obese rats exhibit high levels of isoprostanes in acute pancreatitis

s / Pancreatology 12 (2012) 502–597 538 interference of Sam68 and SRSF1 expression cause a partial recovery of drug sensitivity. Conclusions: Our results show that chronic exposure of PDAC cells to gemcitabine leads to selection of a drug-resistant subpopulation overexpressing Sam68 and SRSF1. Importantly, the depletion of these proteins leads to a partial recovery of the sensibility to gemcitabine, suggesting that they may represent suitable molecular-targets to overcome drug resistance in PDAC.

Oligonucleotide probes detect splicing variants insituinDrosophilaembryos

1992

We describe a method for the in situ detection of specific splicing variants. The method is based on the use of antisense oligonucleotides designed to span splice junctions labelled with digoxigenin by terminal transferase tailing. We find that the spatial patterns of Ubx splicing variants Ia and IIa are similar in early embryos, but differ in late embryos. Variant IVa is only detected in the CNS (ps6) at stages 16 and 17. We also present evidence indicating that the first splicing event is cotranscriptional.

Phenguignardic acid and guignardic acid, phytotoxic secondary metabolites from Guignardia bidwellii.

2012

Bioactivity-guided isolation led to the identification of phenguignardic acid (2), a new phytotoxic secondary metabolite from submerged cultures of grape black rot fungus, Guignardia bidwellii. The compound is structurally related to guignardic acid (1), a dioxolanone moiety-containing metabolite isolated previously from Guignardia species. However, in contrast to guignardic acid, which is presumably synthesized from deamination products of valine and phenylalanine, the biochemical precursor for the biosynthesis of the new phytotoxin appears to be exclusively phenylalanine. Guignardic acid was also found in extracts of cultures from Guignardia bidwellii. The phytotoxic activities of both co…

Activation of the lectin pathway in murine lupus nephritis.

2004

In systemic lupus erythematosus (SLE), hypocomplementaemia and complement deposition have been described both in man and in experimental models. A major involvement of the classical pathway of complement activation has been demonstrated in this disease, however relatively little is known about the involvement of the lectin pathway. Therefore in the present study we have analyzed the activity of all three pathways of complement activation in murine models of SLE. In the mouse, MBL is expressed in two forms, namely MBL-A and MBL-C. In the present study young and old MRL-lpr and control MRL+/+ mice were compared for the levels of complement activity with specific attention for the lectin pathw…
