Written Corrective Feedback and the Development of L2 Learner Language : A longitudinal study of lower secondary EFL writing in Norway

Master´s thesis in English (EN501)Aiming to explore teacher written corrective feedback and learner errors qualitatively and longitudinally, the present study investigates two teachers’ WCF to errors in the written production of three lower secondary EFL students in Norway over the course of three school years. The study is divided in four parts: an error analysis of the students’ writing once every six months, a feedback analysis of the teachers’ WCF to errors in the same samples of writing, a tracking of possible improvement in selected types of errorsin subsequent writing (for error categories corrected by the teacher and revised by the student), and a semi-structured interview to include the teachers’ perspective and beliefs about WCF practice, both their own and in general. The study revealed that the participating students did not work enough with revision to benefit from the learning potential of the teachers’ WCF. Additionally, it seems that authentic teacher WCF is neither focused nor comprehensive, but rather somewhere in between

The 3Rs in Animal Welfare Bodies at Swedish Universities - Knowledge, Attitudes, Implementation

The implementation of the 3Rs (replacement, reduction and refinement) is emphasized in EU Directive 2010/63.16 task of the animal welfare bodies (AWB) is to strengthen animal welfare and develop the 3Rs at research animal facilities. In 2016, we surveyed the knowledge on, attitudes towards and implementation of the 3Rs within AWBs at eight major Swedish universities. Based on responses of 34 closed-ended questions from 44 of 90 AWB members, the overall attitude towards the 3Rs was positive. AWB members did not believe that the 3Rs slow down innovation or result in increased costs, and refinement was considered beneficial for research quality. AWB members were particularly positive towards refinement questions in the survey. A majority of the AWB members predicted that alternative methods will never replace animal use. Researchers as a group represented in the AWBs were significantly less positive towards the 3Rs compared to the group of veterinarians. The tasks of the AWBs, e.g., giving advice on the 3Rs and following up on animal use in projects, were often not carried out in the AWB or not known by the respondents. Our results indicate a need for more practical and regulatory guidance and support to the AWBs. To reach the goal of the EU Directive to phase out animal use in research and education, we suggest that technical expertise in replacement techniques is included in the AWBs. We emphasize the need to strengthen the awareness of the 3Rs among researchers at Swedish universities

Design and construction of the Tracking Written Learner Language (TRAWL) Corpus: A longitudinal and multilingual young learner corpus

This article describes the design and construction of the Tracking Written Learner Language (TRAWL) Corpus. The corpus combines several features that are all rare for learner corpora: it is longitudinal, following individual pupils over several years; it has data from young learners from school years 5 to 13 (ages 10–18); it is multilingual, containing learners’ texts in several L3s (French, German and Spanish), L2 English and L1 Norwegian; and it includes teacher comments on a number of the texts. In addition, some of the texts exist in both a first and a second revised version, all tied to a rich set of meta-data. Not only does such a corpus offer new possibilities for research on language acquisition in general; it can also be used to provide valuable insights for teachers, teacher training and policymaking within the national context of Norway. In this article, we describe the design of the TRAWL Corpus and outline its uses and benefits for the research community. We also describe the compilation process in the hope that it may inspire and enable others to build similar corpora for their own national contexts.publishedVersio

To explore patient perception of sexual quality of life (SQOL), an important category of QOL, in male and female patients with axial SpA (axSpA) after a 5 year follow-up. Methods. A broad spectrum of demographic, disease-related, treatment and SQOL data was collected at baseline and at the 5 year follow-up. SQOL was assessed by the SQOL-Female (SQOL-F) questionnaire. For statistical analysis, McNemar’s tests, paired t-tests and multiple regression analyses were applied. Results. A total of 245 axSpA patients (168 men and 77 women) from outpatient clinics were examined (mean age 46 years, mean disease duration 11.9 years at baseline). Compared with baseline, the patients had lower CRP, lower Maastricht Ankylosing Spondylitis Enthesitis Scores, lower BASFI scores, less use of smoking and significantly more patients were treated with biologic DMARDs at the 5 year follow-up. Patient perception of SQOL was basically unchanged at the 5 year follow-up despite a significantly increased proportion of comorbidities, including cardiovascular, endocrine and gastrointestinal disease. A decrease in SQOL after 5 years was observed only in patients exercising 65 years old. Conclusion. In our axSpA patients, no statistically significant changes in SQOL were observed over 5 years, despite a significant increase in comorbidities. Overall disease symptoms decreased, indicating better disease control. Increased use of biologic drugs at the 5 year follow-up may have contributed to this favourable outcome.acceptedVersio

Small intestinal CD103+ dendritic cells display unique functional properties that are conserved between mice and humans

A functionally distinct subset of CD103+ dendritic cells (DCs) has recently been identified in murine mesenteric lymph nodes (MLN) that induces enhanced FoxP3+ T cell differentiation, retinoic acid receptor signaling, and gut-homing receptor (CCR9 and α4β7) expression in responding T cells. We show that this function is specific to small intestinal lamina propria (SI-LP) and MLN CD103+ DCs. CD103+ SI-LP DCs appeared to derive from circulating DC precursors that continually seed the SI-LP. BrdU pulse-chase experiments suggested that most CD103+ DCs do not derive from a CD103− SI-LP DC intermediate. The majority of CD103+ MLN DCs appear to represent a tissue-derived migratory population that plays a central role in presenting orally derived soluble antigen to CD8+ and CD4+ T cells. In contrast, most CD103− MLN DCs appear to derive from blood precursors, and these cells could proliferate within the MLN and present systemic soluble antigen. Critically, CD103+ DCs with similar phenotype and functional properties were present in human MLN, and their selective ability to induce CCR9 was maintained by CD103+ MLN DCs isolated from SB Crohn's patients. Thus, small intestinal CD103+ DCs represent a potential novel target for regulating human intestinal inflammatory responses

Cleavage of the urokinase receptor (uPAR) on oral cancer cells: Regulation by transforming growth factor - beta1 (TGF-beta1) and potential effects on migration and invasion

Source at https://doi.org/10.1186/s12885-017-3349-7 Background: Urokinase plasminogen activator (uPA) receptor (uPAR) is up-regulated at the invasive tumour front of human oral squamous cell carcinoma (OSCC), indicating a role for uPAR in tumour progression. We previously observed elevated expression of uPAR at the tumour-stroma interface in a mouse model for OSCC, which was associated with increased proteolytic activity. The tumour microenvironment regulated uPAR expression, as well as its glycosylation and cleavage. Both full-length- and cleaved uPAR (uPAR (II-III)) are involved in highly regulated processes such as cell signalling, proliferation, migration, stem cell mobilization and invasion. The aim of the current study was to analyse tumour associated factors and their effect on uPAR cleavage, and the potential implications for cell proliferation, migration and invasion. Methods: Mouse uPAR was stably overexpressed in the mouse OSCC cell line AT84. The ratio of full-length versus cleaved uPAR as analysed by Western blotting and its regulation was assessed by addition of different protease inhibitors and transforming growth factor - β 1(TGF- β 1). The role of uPAR cleavage in cell proliferation and migration was analysed using real-time cell analysis and invasion was assessed using the myoma invasion model. Results: We found that when uPAR was overexpressed a proportion of the receptor was cleaved, thus the cells presented both full-length uPAR and uPAR (II-III). Cleavage was mainly performed by serine proteases and urokinase plasminogen activator (uPA) in particular. When the OSCC cells were stimulated with TGF- β 1, the production of the uPA inhibitor PAI-1 was increased, resulting in a reduction of uPAR cleavage. By inhibiting cleavage of uPAR, cell migration was reduced, and by inhibiting uPA activity, invasion was reduced. We could also show that medium containing soluble uPAR (suPAR), and cleaved soluble uPAR (suPAR (II-III)), induced migration in OSCC cells with low endogenous levels of uPAR. Conclusions: These results show that soluble factors in the tumour microenvironment, such as TGF- β 1, PAI-1 and uPA, can influence the ratio of full length and uPAR (II-III) and thereby potentially effect cell migration and invasion. Resolving how uPAR cleavage is controlled is therefore vital for understanding how OSCC progresses and potentially provides new targets for therapy

Patient-derived organoids reflect the genetic profile of endometrial tumors and predict patient prognosis

Background: A major hurdle in translational endometrial cancer (EC) research is the lack of robust preclinical models that capture both inter- and intra-tumor heterogeneity. This has hampered the development of new treatment strategies for people with EC. Methods: EC organoids were derived from resected patient tumor tissue and expanded in a chemically defined medium. Established EC organoids were orthotopically implanted into female NSG mice. Patient tissue and corresponding models were characterized by mor- phological evaluation, biomarker and gene expression and by whole exome sequencing. A gene signature was defined and its prognostic value was assessed in multiple EC cohorts using Mantel-Cox (log-rank) test. Response to carboplatin and/or paclitaxel was measured in vitro and evaluated in vivo. Statistical difference between groups was calculated using paired t-test. Results: We report EC organoids established from EC patient tissue, and orthotopic organoid-based patient-derived xenograft models (O-PDXs). The EC organoids and O-PDX models mimic the tissue architecture, protein biomarker expression and genetic profile of the original tissue. Organoids show heterogenous sensitivity to conventional chemotherapy, and drug response is reproduced in vivo. The relevance of these models is further supported by the identification of an organoid-derived prognostic gene signature. This signature is vali- dated as prognostic both in our local patient cohorts and in the TCGA endometrial cancer cohort. Conclusions: We establish robust model systems that capture both the diversity of endo- metrial tumors and intra-tumor heterogeneity. These models are highly relevant preclinical tools for the elucidation of the molecular pathogenesis of EC and identification of potential treatment strategies.publishedVersio

The prognostic effect of KRAS mutations in non-small cell lung carcinoma revisited: A norwegian multicentre study

Background: due to emerging therapeutics targeting KRAS G12C and previous reports with conflicting results regarding the prognostic impact of KRAS and KRAS G12C in non-small cell lung cancer (NSCLC), we aimed to investigate the frequency of KRAS mutations and their associations with clinical characteristics and outcome. Since mutation subtypes have different preferences for downstream pathways, we also aimed to investigate whether there were differences in outcome according to mutation preference for the Raf, PI3K/Akt, or RalGDS/Ral pathways. Methods: retrospectively, clinicopathological data from 1233 stage I–IV non-squamous NSCLC patients with known KRAS status were reviewed. KRAS’ associations with clinical characteristics were analysed. Progression free survival (PFS) and overall survival (OS) were assessed for the following groups: KRAS wild type (wt) versus mutated, KRAS wt versus KRAS G12C versus KRAS non-G12C, among KRAS mutation subtypes and among mutation subtypes grouped according to preference for downstream pathways. Results: a total of 1117 patients were included; 38% had KRAS mutated tumours, 17% had G12C. Among KRAS mutated, G12C was the most frequent mutation in former/current smokers (45%) and G12D in never smokers (46%). There were no significant differences in survival according to KRAS status, G12C status, among KRAS mutation subtypes or mutation preference for downstream pathways. Conclusion: KRAS status or KRAS mutation subtype did not have any significant influence on PFS or OS
