  2. 16. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular

    Author : Mia Stenberg; Patrik Andersson; Miriam Jacobs; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; industrial chemicals; in silico tools; molecular descriptors; non-dioxin-like PCBs; partial least-squares PLS ; principal component analysis PCA ; quantitative structure-activity relationship QSAR ; REACH; risk assessment RA ; statistical molecular design; structure-activity relationship SAR ;

    Abstract : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. READ MORE

  4. 17. Connective tissue contraction in wound healing : An experimental study in vivo and in vitro

    Author : M. Reza Ghassemifar; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Contraction of connective tissue is an important part of tissue repair that reduces the wound space and helps to decrease the formation of scar tissue, both of which are needed to restore tissue integrity. In the present study, certain cellular mechanisms that are active during connective tissue contraction were assessed and the influence of transforming growth factor-. READ MORE

  5. 18. Exploring the role of rheology in bolus flow using an in-vitro approach

    Author : Muhammad Waqas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extensional rheology; ultrasound viscometery; Bolus rheology; in vivo analysis; in vitro manometry; In-vitro simulations; degluitition; microstructure analysis; thickened fluids; Dysphagia;

    Abstract : Swallowing disorders, termed ‘dysphagia’, are more common in the elderly but can also affect younger persons. Approximately, 8% of the world’s population suffers from dysphagia. A Texture Modified Diet (TMD), which increases bolus viscosity to adjust for the sluggish bolus handling mechanism, is the most common intervention. READ MORE

  6. 19. Growth regulation in sarcomas : studies in vivo and in cell culture

    Author : Avni Abdiu; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Sarcomas are malignant tumors of mesenchymal origin, and can arise in soft-tissue and in bones. It has been suggested that the abnormal growth regulation in sarcoma cells may be due to an autocrine mechanism, in which the cells are stimulated by an endogenous production of growth factors.
