1. 1. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

   Författare :Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

   Sammanfattning : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. LÄS MER

3. 2. The effect of mechanical ventilation on the abdominal organs

   Författare :Silvia Marchesi; Miklós Lipcsey; Anders Larsson; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; abdominal organs; diffusion weighted imaging; magnetic resonance; perfusion; edema; inflammation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Sammanfattning : During mechanical ventilation (MV), the interplay between abdomen and thorax has been studied unilaterally focusing on the effect that an increased abdominal pressure would have on the thorax. Only a small cluster of studies offered a different perspective showing a lower inflammation and a better lymphatic clearance of edema in abdominal organs when spontaneous breathing was applied compared to MV.

4. 3. Cerebral Perfusion during Cardiopulmonary Bypass

   Författare :Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Impaired superior vena cava (SVC) cannula outflow during cardiopulmonary bypass (CPB) is a frequent issue, often manifested by only marginal changes in routine monitoring parameters. Nevertheless, significant impact on cerebral perfusion may result. LÄS MER

5. 4. Anal Fistula : Aspects of Aetiology, Diagnosis and Prognosis After Surgical Treatment

   Författare :Ulla-Maria Gustafsson; Wilhelm Graf; Torgny Svenberg; Uppsala universitet; []
   Nyckelord :Surgery; anal fistula; risk factors; endoanal advancement flap; anal incontinence; endoanal ultrasound; magnetic resonance imaging; gentamicin-collagen; micro perfusion; laser Doppler flowmetry; Kirurgi;

   Sammanfattning : Patients with idiopathic anal fistula (n=85) were compared with 215 control subjects, matched for age and sex, through a 180-item questionnaire. Obesity, smoking, constipation and bowel symptoms associated with IBS were more common in the patients. LÄS MER

7. 5. Perfusion computed tomography of the liver

   Författare :Katharina Brehmer; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Perfusion CT (P-CT) is a relatively new imaging technique that permits the visual and quantitative assessment of the micro- and macrocirculation of a target organ and focal lesions. P-CT has shown promising results in the evaluation of hyper-vascular tumors such as hepatocellular carcinoma (HCC). LÄS MER
