- In this study, a previously evaluated guided Internet-based cognitive behavior therapy for social anxiety disorder (SAD) was adapted for mobile phone administration (mCBT). The treatment was compared with a guided self-help treatment based on interpersonal psychotherapy (mIPT). The treatment platform could be accessed through smartphones, tablet computers, and standard computers. A total of 52 participants were diagnosed with SAD and randomized to either mCBT (n = 27) or mIPT (n = 25). Measures were collected at pre-treatment, during the treatment, post-treatment and 3-month follow-up. On the primary outcome measure, the Liebowitz Social Anxiety Scale - self-rated, both groups showed statistically significant improvements. However, mCBT performed significantly better than mIPT (between group Cohen's d = 0.64 in favor of mCBT). A larger proportion of the mCBT group was classified as responders at post-treatment (55.6% versus 8.0% in the mIPT group). We conclude that CBT for SAD can be delivered using modern information technology. IPT delivered as a guided self-help treatment may be less effective in this format. (c) 2014 Elsevier Ltd.

- In this study, beta-glucan in samples of sifted flour from six barley varieties was sequentially extracted with water and NaOH obtaining three fractions: water-extractable (WE), NaOH- extractable (NaE) and residual (Res). beta-Glucan isolates were incubated with lichenase and oligomers released were analysed with high performance anion exchange chromatography coupled with pulsed amperometric detection (HPAEC-PAD). A higher ratio of 3-O-beta-cellobiosyl-D-glucose (DP3) to 3-O-beta-cellotriosyl-D-glucose (DP4) is reported in WE, NaE and Res fractions in variety SLU 7 (shrunken endosperm) compared to the other varieties, suggesting a more packed beta-glucan structure. Water-extractable and water-unextractable beta-glucan fractions were incubated with wheat extract and effects of wheat beta-glucanase on the structure was assessed after lichenase digestion and analysis with HPAEC-PAD. Findings suggest that wheat beta-glucanase manifests a selective hydrolysis towards beta-glucan with lower DP3/DP4 ratio and that beta-glucan of SLU 7 is composed of a population with higher DP3/DP4 ratio and hence with a more tighten structure which may be more resistant to enzymic action. Overall, the results obtained are of interest to characterise barleys differing in starch and dietary fibre composition, specifically shrunken endosperm barley SLU 7 in the perspective of its inclusion in the production of beta-glucan enriched foods.

- Age has a major effect on brain volume. However, the normative studies available are constrained by small sample sizes, restricted age coverage and significant methodological variability. These limitations introduce inconsistencies and may obscure or distort the lifespan trajectories of brain morphometry. In response, we capitalized on the resources of the Enhancing Neuroimaging Genetics through Meta-Analysis (ENIGMA) Consortium to examine age-related trajectories inferred from cross-sectional measures of the ventricles, the basal ganglia (caudate, putamen, pallidum, and nucleus accumbens), the thalamus, hippocampus and amygdala using magnetic resonance imaging data obtained from 18,605 individuals aged 3-90 years. All subcortical structure volumes were at their maximum value early in life. The volume of the basal ganglia showed a monotonic negative association with age thereafter; there was no significant association between age and the volumes of the thalamus, amygdala and the hippocampus (with some degree of decline in thalamus) until the sixth decade of life after which they also showed a steep negative association with age. The lateral ventricles showed continuous enlargement throughout the lifespan. Age was positively associated with inter-individual variability in the hippocampus and amygdala and the lateral ventricles. These results were robust to potential confounders and could be used to examine the functional significance of deviations from typical age-related morphometric patterns.

- In this study, 50% sifted barley flour from six different varieties and 50% refined wheat flour was used to bake bread. The flour mixture and the bread crumb and crust were analysed for content and composition of total dietary fibre, arabinoxylan, fructan, beta-glucan, starch and resistant starch. Total dietary fibre content and extractability were not changed significantly by bread making. The extractability of mixed linkage (1 -> 3), (1 -> 4)- beta-D-glucan (beta-glucan) increased with baking, while the average molecular weight of beta-glucan decreased. However in one variety, SW 7, higher average molecular weight was maintained and a different pattern was apparent in the molecular weight distribution. SLU 7 is thereby promising for inclusion in bread where a higher molecular weight of beta-glucan is preferred, especially since the content of beta-glucan in SLU 7 is high. The resistant starch formed positively correlated with amylose content. The high amylose variety yielded 2.9% resistant starch in the bread crumb, making an important contribution to total dietary fibre. (C) 2017 Elsevier Ltd. All rights reserved.

- Barley is a rich source of dietary fibre that can promote beneficial physiological effects. The carbohydrate composition in different barley varieties differs considerably and choice of variety is thus important. This study examined whether differences in carbohydrate composition observed in barley kernels of different varieties persisted in the sifted flour and in an extruded product. Six barley varieties were milled and extruded and dietary fibre and starch in the kernels, flour and extruded product were analysed. The starch content was found to be higher in flour and extruded product than in kernels. The content of arabinoxylan was higher in sifted flour than in kernels, but was decreased by extrusion. The extractability of arabinoxylan was increased by extrusion, while its average molecular weight was decreased. Extrusion also decreased the content of mixed-linkage (1 -> 3),(1 -> 4)-beta-D-glucan in all varieties, but increased its extractability. The six barley varieties were affected in much the same way by milling and extrusion, but clear differences could still be observed. For example, the arabinoxylan in variety SW 28708 was less affected and variety KVL 301 had much lower extractability (76% vs 91-98%) of mixed-linkage (1 -> 3),(1 -> 4)-beta-D-glucan after extrusion than the other varieties.

Genetic Studies of Pigmentation in Chicken
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Domestic animals have been selected by humans for thousands of years, which have drastically altered their genetic constitution and phenotypes. In this thesis, several of the most important genes causing pigmentation differences between the wild red junglefowl (Gallus gallus) and domestic chickens have been identified. Pigmentation phenotypes are easily scored, and the genes underlying these phenotypes are valuable models to study gene function and gene interaction. Dominant white colour is widespread among domestic chickens. The Dominant white allele specifically inhibits the expression of black (eumelanin) pigment and we identified several insertion/deletion mutations in the PMEL17 gene causing the different phenotypes controlled by this locus. The Silver allele on the other hand inhibits the expression of red (pheomelanin) colour and is a genetic variant of the SLC45A2 gene. Silver is the first pheomelanin-specific mutation(s) reported for this gene. An 8 kb deletion, including a conserved enhancer element, 14 kb upstream of the transcription factor SOX10 is causing the Dark brown phenotype. This phenotype restricts the expression of eumelanin and enhances red pheomelanin in specific parts of the plumage. These three gene identifications have extended the knowledge about genes affecting melanocyte function. Carotenoid-based pigmentation is of utmost importance in birds and other animals. The yellow skin allele in chicken allows deposition of carotenoids in skin and explains why most domestic chickens have yellow legs. We demonstrated that the yellow skin phenotype is caused by a tissue specific regulatory mutation in the gene for the enzyme beta-caroten dioxygenase 2 (BCDO2). This was the first identification of a specific gene underlying carotenoid-based pigmentation. Interestingly, the yellow skin haplotype was shown to originate from the grey junglefowl (Gallus sonneratii) and not the red junglefowl as expected, thus presenting the first conclusive evidence for a hybrid origin of the domestic chicken.

- Objective: To explore dieticians', occupational therapists' and physical therapists' attitudes, beliefs, knowledge and behaviour concerning evidence-based practice within a university hospital setting. Design: Cross-sectional survey. Setting. University hospital. Participants: All dieticians, occupational therapists and physical therapists employed at a Swedish university hospital (n = 306) of whom 227 (74%) responded. Main Outcome Measures: Attitudes towards, perceived benefits and limitations of evidence-based practice, use and understanding of clinical practice guidelines, availability of resources to access information and skills in using these resources. Results: Findings showed positive attitudes towards evidence-based practice and the use of evidence to support clinical decision-making. It was seen as necessary. Literature and research findings were perceived as useful in clinical practice. The majority indicated having the necessary skills to be able to interpret and understand the evidence, and that clinical practice guidelines were available and used. Evidence-based practice was not perceived as taking into account the patient preferences. Lack of time was perceived as the major barrier to evidence-based practice. Conclusions: The prerequisites for evidence-based practice were assessed as good, but ways to make evidence-based practice time efficient, easy to access and relevant to clinical practice need to be continuously supported at the management level, so that research evidence becomes linked to work-flow in a way that does not adversely affect productivity and the flow of patients. © The Author 2011.
