    Abstract : HIV-1 invades the central nervous system (CNS) early in the infectious course. It establishes a chronic progressive infection, and triggers an intrathecal immune response. If left untreated, a majority of patients will develop neurological complications, caused by opportunistic pathogens or HIV-1 itself. READ MORE

  5. 18. Acupuncture in Obstetrics and Anaesthesia

    Abstract : The aims of the present thesis (I-V) were to evaluate the analgesic and adverse effects of manual acupuncture for low-back and pelvic pain during pregnancy (I) and for labour pain (II-III), and also to study the effects of low-frequency electro acupuncture (EA) on clinical physiological responses to skin incision in anaesthetized patients (IV-V). Acupuncture in obstetric patients (I-III) Manual acupuncture in obstetric patients was found to relieve pain in one prospective randomised (I) and two retrospective (II-III) studies. READ MORE

  6. 19. The Role of Odor and Sensory Irritation in Human Chemical Sensitivity

    Author : Li Zheng; Birgitta Berglund; Staffan Hygge; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Odor and irritation detection; recognition; threshold; choice theory; intensity; chemical sensitivity; threshold; and sensitivity index.; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The main objective of this thesis is to apply complimentary psychophysical theories and methods to investigate human perception of odor and sensory irritation of chemical compounds present in indoor air. Three psychophysical theories: Signal Detection Theory (SDT), Threshold Theory and Luce’s Choice Theory (CT) were applied to measure detection and recognition of odor and sensory irritation of two odorous irritants (pyridine and formaldehyde) by using the method of constant stimuli.
