2. 1. Le Fantôme de l’Opéra - Studies on Atoms and Electrons Beneath

   Author : Chang Liu; Lars G. M. Pettersson; Anders Nilsson; Anders Hellman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide reduction; Subsurface oxygen; X-ray spectroscopy; Density functional theory; CO desorption; teoretisk fysik; Theoretical Physics;

   Abstract : The carbon dioxide reduction reaction is a promising candidate to tackle ecological challenges of our age. This is due to its capability of reducing carbon dioxide emission generated from the combustion of fossil fuels by converting carbon dioxide into valuable hydrocarbons. READ MORE

4. 2. About hyaluronan in the hypertrophic heart : studies on coordinated regulation of extracellular matrix signalling

   Author : Urban Hellman; Anders Waldenström; Stellan Mörner; Anna Engström-Laurent; Lena Jonasson; Umeå universitet; []
   Keywords : hyaluronan; hyaluronan synthases; gene expression; extracellular matrix; cardiac hypertrophy; rat wistar; male ; cardiomyocytes; growth factors; fibroblasts; microvesicles; exosomes; MEDICINE; MEDICIN; Medicine; medicin;

   Abstract : Background. Myocardial hypertrophy is a risk factor for cardiovascular morbidity and mortality. Independent of underlying disease, the cardiac muscle strives in different ways to compensate for an increased workload. This remodelling of the heart includes changes in the extracellular matrix which will affect systolic and diastolic cardiac function. READ MORE

5. 3. Gastric Bypass : Facilitating the Procedure and Long-term Results

   Author : David Edholm; Magnus Sundbom; Per Hellman; Anders Thorell; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morbid obesity; Gastric bypass; Laparoscopy; Low-calorie diet; Magnetic resonance imaging; Magnetic resonance spectroscopy; Kirurgi; Surgery;

   Abstract : Gastric bypass achieves weight loss in the morbidly obese. Preoperative weight loss is used to reduce the enlarged fatty liver that otherwise reduces visibility during surgery. The purpose of gastric bypass is to provide patients with long-term weight loss. READ MORE

6. 4. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling

   Author : Nina Gennebäck; Stellan Mörner; Anders Waldenström; Urban Hellman; Ali J Marian; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac hypertrophy; HCM; gene expression; OPLS-DA; multivariate dataanalysis; cardiomyocytes; exosomes; microvesicles; Medicine; medicin;

   Abstract : Background: The aim of this thesis was to study transcription patterns and extracellular signalling of the hypertrophic heart to better understand the mechanisms initiating, controlling and maintaining cardiac hypertrophy.Cardiac hypertrophy is a risk factor for cardiovascular morbidity and mortality.

7. 5. Irreversible electroporation of pancreatic adenocarcinoma

   Author : Christopher Månsson; Britt-Marie Karlson; Anders Nilsson; Per Hellman; Sara Regnér; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic Neoplasms; Electroporation; Interventional Ultrasonography; CA 19-9.;

   Abstract : Pancreatic cancer (PC) is a severe diagnosis with poor prognosis. Radical surgery is the only treatment that can possibly lead to a cure, and even with surgery, the 5-year survival is only 20%–25%. The majority of patients cannot be resected due to metastases or having a tumour that is too advanced locally (LAPC) with encasement of blood-vessels. READ MORE
