2. 1. In search of the missing bias : Virtual reality based attentional bias modification for social anxiety

   Author : Lichen Ma; Per Carlbring; Martien Schrooten; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; attentional bias; attentional bias modification; social anxiety; virtual reality; dot-probe; attentional training; mixed reality; Psychology; psykologi;

   Abstract : Attentional bias modification (ABM) aims to attenuate social anxiety by directly modifying the underlying bias that generates and maintains problematic anxiety. Mixed results from previous ABM studies have spurred efforts to boost its effectiveness by introducing more robust bias modification protocols and new technologies. READ MORE

4. 2. The puzzle of lichen symbiosis : Pieces from Thamnolia

   Author : Ioana Onuț-Brännström; Hanna Johannesson; Leif Tibell; Anne Pringle; Uppsala universitet; []
   Keywords : Thamnolia; lichen; symbiosis; photobiont; mycobiont; phylogeography; MAT-loci; barcoding; NGS; genome; transcriptome; Ice Age; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

   Abstract : Symbiosis brought important evolutionary novelties to life on Earth. Lichens, the symbiotic entities formed by fungi, photosynthetic organisms and bacteria, represent an example of a successful adaptation in surviving hostile environments. Yet many aspects of the lichen symbiosis remain unexplored. READ MORE

5. 3. Oral lichen planus : studies of factors involved in differentiation, epithelial mesenchymal transition and inflammation

   Author : Karin Danielsson; Karin Nylander; Ylva Britt Wahlin; Linda Boldrup; Jesper Reibel; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oral lichen planus; differentiation; inflammation; autoimmune; premalign; odontologi; Odontology; patologi; Pathology;

   Abstract : Background: Lichen planus is a chronic inflammation of skin and mucosa with unknown cause. Oral Lichen Planus, OLP, affects around 2% of the population. Autoimmunity has been suggested as a possible cause as the disease has autoimmune features such as female predominance, cyclic nature and cytotoxic T-cell infiltrate. READ MORE

7. 5. Modeling lichen performance in relation to climate : scaling from thalli to landscapes

   Author : Anna V Jonsson Čabrajić; Kristin Palmqvist; Jon Moen; Per-Anders Esseen; Mikaell Ottosson-Löfvenius; Göran Ågren; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lichen; growth; model; micro-climate; hydration; activation; photosynthesis; respiration; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

   Abstract : Lichens can colonize nearly all terrestrial habitats on earth and are functionally important in many ecosystems. Being poikilohydric, their active growth periods are restricted to periods when the thallus is hydrated from atmospheric water sources, such as rain, fog and high relative humidity. READ MORE
