2. 1. Stability of bacterial DNA in relation to microbial detection in teeth

   Author : Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

   Abstract : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. READ MORE

4. 2. Perturbance and Stimulation : using Nitrogen Addition and High-Throughput Sequencing to Study Fungal Communities in Boreal Forests

   Author : Andreas N. Schneider; Nathaniel Street; Vaughan Hurry; Torgny Näsholm; Colin Averill; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boreal forest; Scots pine; Norway spruce; ectomycorrhiza; saprotroph; fertilization; nitrogen; mycobiome; rhizosphere; decomposition; carbon; seedling establishment; forest management; clearcutting;

   Abstract : Fungal communities are major players in globally important nutrient cycling processes, and form symbioses with most terrestrial plants. In the nitrogen (N) limited Swedish boreal forest, ectomycorrhizal (EcM) fungi colonize most roots of the economically important and stand dominating conifer species, Norway spruce (Picea abies) and Scots pine (Pinus sylvestris), with significant implications for tree nutrition and decomposition processes.

5. 3. Dimension Reduction and Signal Decomposition for Genotype–Phenotype Relations

   Author : Rasmus Perby Henningsson; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematik; Bioinformatik; Dimensionsreduktion; Computational mathematics; Bioinformatics; Dimension reduction;

   Abstract : Over the last few decades, DNA sequencing has developed from costing billions of dollars to get the complete sequence of the human genome, to being a routine procedure performed in labs all around the world. This has transformed the field of experimental biology since measurements can be done at a level of detail that was not possible before. READ MORE

6. 4. Mycorrhizal guild functions and conservational values in boreal forests

   Author : Louis Mielke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : The immense diversity and biomass of ericoid-, ectomycorrhizal, and saprotrophic fungal guilds in boreal forest soils make them vital components of conservation and ecosystem processes, and in particular, many ectomycorrhizal fungi are considered species of conservation concern. However, amalgamated information on the functions and relationships of soil fungi to perceived forest conservation values, and how inter and intra-guild interactions affect the accretion and decomposition of soil organic matter is lacking.

7. 5. Mapping the proteome with data-driven methods: A cycle of measurement, modeling, hypothesis generation, and engineering

   Author : Filip Buric; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tensor factorization; mass spectrometry; model interpretation; sequence feature engineering; deep learning; proteomics; machine learning; data-independent acquisition; feature learning;

   Abstract : The living cell exhibits emergence of complex behavior and its modeling requires a systemic, integrative approach if we are to thoroughly understand and harness it. The work in this thesis has had the more narrow aim of quantitatively characterizing and mapping the proteome using data-driven methods, as proteins perform most functional and structural roles within the cell.
