    Abstract : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. READ MORE

  5. 3. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening

    Author : Alejandro Vicente Carrillo; Heriberto Rodríguez-Martínez; Karl-Eric Magnusson; Rudolf Rigler; Vesa Loitto; Stefan Arver; Linköpings universitet; []

    Abstract : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. READ MORE

  6. 4. Decoding the language of transmission among vector-pathogen-host

    Author : Melika Hajkazemian; S. Noushin Emami; Richard Hopkins; Stockholms universitet; []

    Abstract : Vector-borne diseases account for over 17 percent of all infectious diseases and lead to more than 700,000 mortalities annually. Importantly, there is a complex interaction between infectious organisms and their host. READ MORE

  7. 5. Advancing Metabolic Engineering through Combination of Systems Biology and Adaptive Evolution

    Author : Kuk-ki Hong; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; galactose utilization; systems biology; Ras PKA signaling pathway; evolutionary engineering; pleiotropy of evolutionary strategies;

    Abstract : Understanding evolutionary strategies of microorganisms may provide opportunities foradvanced strain development with the aim to produce valuable bio-products from renewablebiomass resources. Through evolutionary processes, microorganisms can attain new traitsassociated with genetic changes that may be useful for the construction of improved strains. READ MORE
