  1. 1. Probabilistic Programming for Birth-Death Models of Evolution

    Author : Jan Kudlicka; Johannes Borgström; Thomas B. Schön; Lawrence M. Murray; Bret Larget; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; probabilistic programming; birth-death models; statistical phylogenetics; particle filters; sequential Monte Carlo SMC ; Computer Science; Datavetenskap;

    Abstract : Phylogenetic birth-death models constitute a family of generative models of evolution. In these models an evolutionary process starts with a single species at a certain time in the past, and the speciations—splitting one species into two descendant species—and extinctions are modeled as events of non-homogenous Poisson processes.

  2. 2. Leukotriene C4 synthase : studies on oligomerization and subcellular localization

    Author : Jesper Svartz; Mats Söderström; Sven Hammarström; Colin Funk; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Leukotrienes (LTs) are polyunsaturated fatty acid derivatives formed by oxygenation of arachidonic acid via the 5-lipoxygenase (5-LO) pathway. Upon activation of inflammatory cells 5-LO is translocated to the nuclear envelope where it converts arachidonic acid to the unstable epoxide LTA4. READ MORE

  3. 3. Functional role of neural cell adhesion molecule in tumorigenesis and beta-cell function

    Author : Xiaojie Xian; Göteborgs universitet; []
    Keywords : N-CAM; pericytes; endothelial; tumor; PDGF-B; RipTag; ECM; exocytosis;

    Abstract : Cancer metastasis is the main lethal cause for cancer patients today. It has been demonstrated that angiogenesis is crucial for growth of both primary tumors and metastasis. READ MORE

  4. 4. Photoreceptor degeneration, second order neuron remodeling and glia reactivity in an in vivo and in vitro model of retinal neurodegeneration

    Author : Tanzina Mollick; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicin; Biomedicine;

    Abstract : Photoreceptors have the ability to last during the entire lifespan of an individual. Being the first line of neurons in the visual transduction pathway, their health and maintenance is eminent for proper retinal function. However, photoreceptors are susceptible to neurodegenerative retinal dystrophies. READ MORE

  5. 5. Retinal tumorigenesis and neurodegeneration : strategies to promote tumor cell death and support retinal cell survival to preserve vision

    Author : Tanzina Mollick; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Our vision is central to our quality of life enabling us to interact with our environment and lead productive lives. The ability to see begins in the retina, one of the paramount features of the eye, as it takes on the task of converting light signals to nerve impulses that are relayed to the visual centers of the brain.
