1. 1. High Performance Breath Analysis

   Författare :Jonas Ljungblad; Mia Folke; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Sammanfattning : Alcohol breath testing on a larger scale will save lives. Alcohol abuse is a major contributor to death and disease. Alcohol intake affects the human body by significantly longer response time to external stimuli. In situations where the senses need to be on alert this delay can be the difference between life and death. LÄS MER

3. 2. Evaluations of measurement techniques in functional dyspepsia : electrogastrography, satiety drinking test and 14C-urea breath test

   Författare :Shahab Abid; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :functional dyspepsia; electrogastrography; 14C urea breath test; satiety drinking test;

   Sammanfattning : The overall aim of this thesis was to evaluate the clinical usefulness of certain measurement techniques that may be helpful in the understanding of functional dyspepsia (FD). Electrogastrography (EGG) parameters were evaluated and found unable to discriminate one specific motility disorder from other motility disorders of the gut. LÄS MER

4. 3. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry

   Författare :Mikael Gunnarsson; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; Kärnfysik; Nuclear physics; xylose.; glycocholic acid; urea; triolein; Dosimetry; Biokinetic; AMS; Accelerator mass spectrometry; 14C; Breath test;

   Sammanfattning : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. LÄS MER

5. 4. Development of allergic and respiratory symptoms in adolescence and early adulthood : Risk factors and gender differences

   Författare :Pia Kalm-Stephens; Kjell Alving; Andrei Malinovschi; Åsa Neuman; Gunn Engvall; Eva Rönmark; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescents; allergy; asthma; breath test; epidemiology; gender; health status indicator; incidence; nitric oxide; prevalence; wheeze.; Epidemiologi; Epidemiology; Lungmedicin; Lung Medicine; Pediatrik; Pediatrics;

   Sammanfattning : Background: Asthma and allergic diseases have increased in prevalence for several decades and affect a substantial number of individuals in everyday life, as well as their families and public healthcare resources. Subjects with asthma report impaired self-rated health. LÄS MER

7. 5. Respiratory drive assessment : an evaluation of the breath-by-breath occlusion pressure method in man

   Författare :Lars Gösta Hellström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : A simplified concept of respiratory drive is to consider it as the integrated "output" from the CNS to the respiratory "pump" muscles. This drive is a result of a complex central respiratory pattern generation, and can in abnormal situations, e.g. of pathological or pharmacological origin, be altered. LÄS MER
