1. On cardiovascular responses to hypovolemic circulatory stress. An experimental study in man
Abstract : Aged subjects have a decreased tolerance to hypovolemia, which could contribute to their increased cardiovascular morbidity. One possible etiological factor might be an age-related reduction in the efficiency of the baroreceptor reflex axis. READ MORE

2. Cardiovascular responses to hypovolemic circulatory stress in women : With special reference to venous compliance and capacitance
Abstract : Acute haemorrhage is a leading cause of death in trauma. Young women (YW) seem more susceptible to hypovolemic circulatory stress than young men (YM), but the underlying mechanisms are not clear. READ MORE

3. Cardiovascular regulation in women with vasovagal syncope : With special reference to the venous system

Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. READ MORE

Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.
