  2. 1. Evolution of signal form

    Author : Liselotte Jansson; Magnus Enquist; Gunilla Rosenqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi;

    Abstract : Visual signals, used for communication both within and between species, vary immensely in the forms that they take. How is it that all this splendour has evolved in nature? Since it is the receiver’s preferences that cause selective pressures on signals, elucidating the mechanism behind the response of the signal receiver is vital to gain a closer understanding of the evolutionary process.

  4. 2. 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

  5. 3. Protein Folding, Binding and Evolution : PDZ domains and paralemmins as model systems

    Author : Greta Hultqvist; Per Jemth; Ruth Nussinov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein folding; evolution; binding; allostery; Paralemmin; PDZ domain;

    Abstract : Proteins present at the synapse need to be multitasking in order to perform all vital functions in this limited space. In this thesis I have analyzed the function and evolution of such proteins, focusing on the PDZ domain and the paralemmin family. The PDZ domains bind to a wide variety of interaction partners.

  6. 4. Elliptical Adaptive Structuring Elements for Mathematical Morphology

    Author : Anders Landström; Jesús Angulo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : As technological advances drives the evolution of sensors as well as the systems using them, processing and analysis of multi-dimensional signals such as images becomes more and more common in a wide range of applications ranging from consumer products to automated systems in process industry. Image processing is often needed to enhance or suppress features in the acquired data, enabling better analysis of the signals and thereby better use of the system in question. READ MORE

  7. 5. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

    Author : Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. READ MORE
