2. 1. Innate and Conditioned Fear : Investigating Responses to Threat using Psychophysiology, Functional Magnetic Resonance Imaging, and Twin Methodology

   Author : Jörgen Rosén; Fredrik Åhs; Miguel Fullana; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Emotion; Imminent threat; Social threat; Twins; Face; Personal space; fMRI; Virtual reality; Amygdala.; Psychology; Psykologi;

   Abstract : Evolution has shaped systems in the human brain to respond to danger. Some of these systems are innate or hard-wired, while others are learned throughout the entire life span. One commonly studied type of learned threat, conditioned fear, is acquired from experiencing aversive consequences. READ MORE

4. 2. Physiological effects of conditioned medium and passage number on Spodoptera frugiperda Sf9 serum free cultures

   Author : Ingrid Svensson; Lena Häggström; Mats Martinelle; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Spodoptera frugiperda Sf9; insect cell cultures; conditioned medium; cell cycle phase dynamics; proteolytic activity; antibacterial activity; recombinant protein production; Bioteknik; Bioengineering; Bioteknik;

   Abstract : The aim of this study was to better understand the role of conditioned medium (CM) in Spodoptera frugiperda Sf9 insect cell proliferation and recombinant protein production using the baculovirus expression system. CM was found to stimulate cell proliferation. READ MORE

5. 3. Regulation of productivity in Trichoplusia ni and Spodoptera frugiperda Sf9 serum-free cultures

   Author : Karin Calles; Lena Häggström; Gunnel Dalhammar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Insect cells; BEVS; Spodoptera frugiperda; Sf9; Trichoplusia ni; BTI-Tn-5B1-4; specific productivity; conditioned medium; conditioned medium factors; cell cycle; synchronization; G2 M; Bioteknik; Bioengineering; Bioteknik;

   Abstract : The aim of this work has been to characterize the effects of conditioned medium (CM) on insect cell productivity and physiology in order to get a better understanding about the mechanisms that regulate productivity in serum-free media. Two cell lines have been investigated, Spodoptera frugiperda (Sf9) and Trichoplusia ni (T. ni, BTI-Tn-5B1-4). READ MORE
