- To identify genetic variants associated with head circumference in infancy, we performed a meta-analysis of seven genome-wide association studies (GWAS) (N = 10,768 individuals of European ancestry enrolled in pregnancy and/or birth cohorts) and followed up three lead signals in six replication studies (combined N = 19,089). rs7980687 on chromosome 12q24 (P = 8.1 x 10(-9)) and rs1042725 on chromosome 12q15 (P = 2.8 x 10(-10)) were robustly associated with head circumference in infancy. Although these loci have previously been associated with adult height(1), their effects on infant head circumference were largely independent of height (P = 3.8 x 10(-7) for rs7980687 and P = 1.3 x 10(-7) for rs1042725 after adjustment for infant height). A third signal, rs11655470 on chromosome 17q21, showed suggestive evidence of association with head circumference (P = 3.9 x 10(-6)). SNPs correlated to the 17q21 signal have shown genome-wide association with adult intracranial volume(2), Parkinson's disease and other neurodegenerative diseases(3-5), indicating that a common genetic variant in this region might link early brain growth with neurological disease in later life.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Vi som har skrivit denna artikel är alla verksamma inom forskningsmiljön Svenska med didaktisk inriktning (SMDI) vid Malmö högskola. Frågor om språkutveckling i bred bemärkelse står här i centrum. För närvarande är vi engagerade i projektet ”SMDI och lärande i medielandskapet 2.0”. Vår teoretiska plattform kan beskrivas som medieekologisk, vilket kortfattat uttryckt innebär att vi är intresserade av de mångfaldiga och komplexa relationerna mellan medier och kommunikativa kompetenser (Elmfeldt & Erixon 2007; Erixon 2012; Hayles 2002). Dessa relationer förstås därför inte, som så ofta annars i skolsammanhang, i termer av enkelriktad påverkan eller effekter (exempelvis datorns och internets negativa inverkan på skriftspråket). Vår huvudpoäng i denna artikel är att medie- och informationskunnighet, MIK, handlar om, borde handla om, framför allt två saker: språkutveckling och demokrati.

- Phosphatidylethanol (PEth) measurement in whole blood samples is established as a specific alcohol biomarker with clinical and forensic applications. Establishment of dried blood spots (DBSs) as a specimen for PEth determination offers several advantages and was the focus of this work. A liquid chromatography tandem mass spectrometry method using a 96-well format for sample preparation was developed and validated. PEth was extracted from DBSs by using isopropanol containing PEth-d5 as internal standard. The blood sampling used a commercial volumetric DBS device having a phosholipase D inhibitor incorporated to stop continuous PEth formation. The method quantified PEth in the range of 0.05-10 mu mol/L, with a bias and imprecision of less than 15%. In a clinical study (n = 25) using fingerprick blood, the volumetric device offered more precise quantifications (CV 4.6%) compared with the Whatman 903 Protein Saver card device (CV 16.6%). In another clinical study (n = 48), the use of dried venous and capillary blood, and liquid venous blood was compared under real-life conditions with samples sent by postal service. The capillary and venous DBS samples gave identical results while the liquid blood gave slightly higher values. Calculation of elimination half-life (PEth 16:0/18:1) in 31 cases based on two consecutive samples with 2-9 days in between gave results (mean 6.2 days) that agree with literature but several cases with values over 10 days. In conclusion, this study demonstrates that volumetric DBS is a valid specimen for determination of PEth blood concentrations, offering several advantages. Phosphatidylethanol, a specific alcohol biomarker, measured in dried blood spots was the focus of this work. A liquid chromatography tandem mass spectrometry method was developed, validated, and applied. The blood sampling used a volumetric DBS device. The volumetric device gave accurate and precise quantifications and the dried capillary blood gave the same results as that of venous blood. image

- Approaches exploiting trait distribution extremes may be used to identify loci associated with common traits, but it is unknown whether these loci are generalizable to the broader population. In a genome-wide search for loci associated with the upper versus the lower 5th percentiles of body mass index, height and waist-to-hip ratio, as well as clinical classes of obesity, including up to 263,407 individuals of European ancestry, we identified 4 new loci (IGFBP4, H6PD, RSRC1 and PPP2R2A) influencing height detected in the distribution tails and 7 new loci (HNF4G, RPTOR, GNAT2, MRPS33P4, ADCY9, HS6ST3 and ZZZ3) for clinical classes of obesity. Further, we find a large overlap in genetic structure and the distribution of variants between traits based on extremes and the general population and little etiological heterogeneity between obesity subgroups.

Tidskriftsartikel (refereegranskat)abstract
- Higher education institutions (HEIs) have a pivotal role in fulfilling the social dimension of sustainability and contributing to a complex changing society. To meet these challenges, Malmö University has in interdisciplinary groups researched the role of challenge-based learning (CBL) in relation to staff, students, disciplines, and stakeholders. This position paper is based on that work. Malmö University argues that with a CBL approach, HEIs will actively contribute to the building of a sustainable learning society through collaboration in education, research, and innovation. This paper theoretically explores the CBL approach as a collaborative learning exchange within HEIs and society at large. CBL is defined through eight key elements, clustered as entities of three domains: diversity and inclusion, co-creation and collaboration, and change agents and contextual challenges. These are discussed and empirically exemplified with the purpose to support designing, planning, and accomplishing CBL in teaching and learning in HE for a global learning society.

- Diets rich in fruit and vegetables promote health and delay the onset of diseases associated with oxidative stress. The benefit, especially of different berries, has been largely attributed to their content of numerous phytochemicals, and their effects in terms of antioxidant capacity are often evaluated chemically by different methods. We have instead used a highly relevant biological model, a modified CAP-e assay (Cell-based Antioxidant Protection in erythrocytes), to evaluate bioefficacy of antioxidants in Swedish berries. Extracts of twelve fruit and berries were analysed both by chemical and biological analyses: apple (Malus domestica, peel), bilberry (Vaccinium myrtillus), black currant (Ribes nigrum), purple chokeberry (Aronia prunifolia), cranberry (Vaccinium macrocarpon), elderberry (Sambucus nigra), lingonberry (Vaccinium vitis-idaea), raspberry (Rubus idaeus), rose hips (Rosa spp.), sea buckthorn (Hippohae rhamnoides), sloe (Prunus spinosa) and strawberry (Fragaria ananassa). Purple chokeberry, sloe and rose hips showed high antioxidant capacity in the chemical assays. Rose hips showed the highest degree of antioxidant protection also in the biological model, however, chokeberry and sloe showed medium or low protection. Furthermore, strawberry showed overall high protection in the biological assay but low antioxidant capacity in the chemical assays. The chemical and biological models showed different results and future studies of the biological model and in vivo situations are necessary
