  2. 1. Signaling pathways in the development of female germ cells

    Author : Deepak Adhikari; Kui Liu; Elisabet Stener-Victorin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ovary; primordial follicle; activation; mTORC₁; PI₃K; oocyte maturation; MPF; Cdk₁; medicinsk biokemi; Medical Biochemistry;

    Abstract : Primordial follicles are the first small follicles to appear in the mammalian ovary. Women are born with a fixed number of primordial follicles in the ovaries. Once formed, the pool of primordial follicles serves as a source of developing follicles and oocytes. READ MORE

  4. 2. Trapezius muscle fatigue and electromyographic frequency analysis

    Author : Tommy Öberg; Linköpings universitet; []
    Keywords : EMG; Spectrum; Frequency; Fatigue; Trapezius; Myalgia; MEDICINE; MEDICIN;

    Abstract : This study, comprising 6 separate articles, is concerned with different validity and reliability aspects of the electromyogram mean power frequency (MPF) as an estimator of localized musele fatigue in the trapezius muscle. A series of new, and partly controversial and problematic findings are reported. READ MORE

  5. 3. Ambulatory Monitoring and Analysis of Surface Electromyographic Signals in Ergonomic Field Studies - Methods and Applications

    Author : Leif Sandsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trapezius; ergonomic assessment tools; long-term recording; wearable systems; EMG; musculoskeletal disorders; work-related;

    Abstract : Factors contributing to and the mechanisms behind the development of work-related musculoskeletal disorders (WMSDs) are still not fully known. Increased knowledge in this area is necessary in order to recommend appropriate actions to counteract the increasing costs to society and reduce the individual suffering related to these problems.

  6. 4. Does acetylcholin play a role in mitosis of V79 Chinese hamster cells?

    Author : Cecilia Söderpalm-Berndes; Stephen M Wolniak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; Genetik; toxikologisk genetik; Genetic Toxicology;

    Abstract : The first stages of mitosis are governed by a cascade of phosphorylations brought about by the universal MPF kinase complex. From a regulatory point of view, less is known about late mitotic events. READ MORE

  7. 5. Separation of Biomass Components by Membrane Filtration - Process Development for Hemicellulose Recovery

    Author : Holger Krawczyk; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; hemicelluloses; pulp mill process water; alkaline extract; membrane filtration;

    Abstract : One of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. READ MORE
