2. 21. Haptoglobin: Biosynthesis and Evolution

   Author : Krzysztof B. Wicher; Erik Fries; John W. M. Creemers; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; haptoglobin; cleavage; C1r-LP; evolution; vertebrate; endoplasmic; Golgi; complement; Molekylärbiologi; Molecular biology; Molekylärbiologi;

   Abstract : Haptoglobin (Hp) is a serum protein known for its ability to form a tight complex with hemoglobin (Hb) and thereby inhibiting the oxidative activity of Hb. Mammalian Hp is synthesized as a precursor (proHp) that undergoes proteolytic cleavage by a previously unidentified enzyme in the endoplasmic reticulum (ER). READ MORE

4. 22. Influenza neuraminidase assembly : Evolution of domain cooperativity

   Author : Diogo da Silveira Vieira da Silva; Robert Daniels; Ron Fouchier; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Influenza; neuraminidase; assembly; transmembrane domain; evolution; Biochemistry; biokemi;

   Abstract : Influenza A virus (IAV) is one of the most common viruses circulating in the human population and is responsible for seasonal epidemics that affect millions of individuals worldwide. The need to develop new drugs and vaccines against IAVs led scientists to study the main IAV surface antigens hemagglutinin (HA) and neuraminidase (NA). READ MORE

5. 23. Sleep disordered breathing : Natural evolution and metabolism

   Author : Ahmed Elmasry; Uppsala universitet; []
   Keywords : Medical sciences; snoring; sleep apnea; epidemiology; obesity; diabetes; catecholamines; hypertension; evolution; population-based; prospective; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Abstract : Sleep disordered breathing is manifested by snoring and repeated episodes of apneas and hypopneas. The induced hypoxia and sleep fragmentation are thought to be responsible for many metabolic disturbances.In 1984, 3,201 men aged 30 to 69 answered a questionnaire on snoring, sleep disorders and somatic diseases. In 1994, 2,668 of the survivors (89. READ MORE

6. 24. Evolution of cellular complexity and other remarkable features in Gemmataceae : Complex bacterial lineages defy prokaryotic trends

   Author : Mayank Mahajan; Siv G. E. Andersson; James O. McInerney; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; Planctomycetes; Gemmataceae; functional organization; signalling; protein interaction; peptidoglycan; membranes; cell division; radiation tolerance; Pfam; SCOP; comparative genomics; protein architecture; domain shuffling and orthologous clustering; Bioinformatics; Bioinformatik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Abstract : Bacteria of the family Gemmataceae belong the phylum Planctomycetes and are remarkable because of their complex cellular architectures, previously considered to be traits exclusive to eukaryotes. This thesis provides clues to the atypical cell envelope, the enhanced radiotolerance and the amazing cellular complexity of these bacteria. READ MORE

7. 25. Probabilistic Modelling of Domain and Gene Evolution

   Author : Sayyed Auwn Muhammad; Jens Lagergren; Bastien Boussau; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Phylogenomics; Evolution; Domain Evolution; Gene tree; Domain tree; Bayesian Inference; Markov Chain Monte Carlo; Homology Inference; Gene families; C2H2 Zinc-Finger; Reelin Protein; Computer Science; Datalogi;

   Abstract : Phylogenetic inference relies heavily on statistical models that have been extended and refined over the past years into complex hierarchical models to capture the intricacies of evolutionary processes. The wealth of information in the form of fully sequenced genomes has led to the development of methods that are used to reconstruct the gene and species evolutionary histories in greater and more accurate detail.
